Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Fiscal Year
	The Company’s fiscal year ends on the last Saturday in December. The fiscal years ended December 27, 2014, December 28, 2013 and December 29, 2012 include 52 weeks, and are referred to as fiscal years 2014, 2013 and 2012, respectively, herein.
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, a majority owned 93% subsidiary, Kowon Technology Co., Ltd. (Kowon), located in Korea, a majority owned 58% subsidiary, Intoware Ltd. (Intoware), located in the United Kingdom, (formerly known as Ikanos Consulting Limited) and a majority owned 80% subsidiary, eMDT America Inc (eMDT), located in California (collectively the Company). All intercompany transactions and balances have been eliminated. Amounts of Kowon, Intoware and eMDT not attributable to the Company are referred to as noncontrolling interests in the consolidated statements of operations and consolidated statements of comprehensive loss. Investments in business entities in which the Company does not have control but has the ability to exercise significant influence over operating and financial policies are accounted for by the equity method.
	In 2013, the Company paid approximately $3.7 million to acquire an additional 15% ownership in its Kowon subsidiary which raised its ownership from 78% to 93%. The Company ceased its production activities at its Kowon facility in 2013 but as of December 27, 2014, the closure of this facility did not meet the criteria for assets held for sale.
	Revenue Recognition
	The Company recognizes revenue if four basic criteria have been met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred and services rendered; (3) the price to the buyer is fixed or determinable; and (4) collectability is reasonably assured. The Company does not recognize revenue for products prior to customer acceptance unless it believes the product meets all customer specifications and the Company has a history of consistently achieving customer acceptance of the product. Provisions for product returns and allowances are recorded in the same period as the related revenues. The Company analyzes historical returns, current economic trends and changes in customer demand and acceptance of product when evaluating the adequacy of sales returns and other allowances. Certain product sales are made to distributors under agreements allowing for a limited right of return on unsold products. Sales to distributors are primarily made for sales to the distributors' customers and not for their stocking of inventory. The Company delays revenue recognition for its estimate of distributor claims of right of return on unsold products based upon its historical experience with the Company’s products and specific analysis of amounts subject to return based upon discussions with the Company’s distributors or their customers.
	The Company recognizes revenues from long-term research and development contracts on the percentage-of-completion method of accounting as work is performed, based upon the ratio of costs or hours already incurred to the estimated total cost of completion or hours of work to be performed. Revenue recognized at any point in time is limited to the amount funded by the U.S. government or contracting entity. The Company accounts for product development and research contracts that have established prices for distinct phases as if each phase were a separate contract. In some instances, the Company is contracted to create a deliverable which is anticipated to be qualified and go into full rate production stages. In those cases, the revenue recognition methodology will change from the percentage of completion method to the units-of-delivery method as new contracts are received after formal qualification has been completed. Under certain of its research and development contracts, the Company recognizes revenue on a milestone methodology.  This revenue is recognized when the Company achieves specified milestones based on its past performance.
	The Company classifies amounts earned on contracts in progress that are in excess of amounts billed as unbilled receivables and classifies amounts received in excess of amounts earned as billings in excess of revenues earned. The Company invoices based on dates specified in the related agreement or in periodic installments based upon its invoicing cycle. The Company recognizes the entire amount of an estimated ultimate loss in its financial statements at the time the loss on a contract becomes known.
	Research and Development Costs
	Research and development expenses are incurred in support of internal display product development programs or programs funded by agencies or prime contractors of the U.S. government and commercial partners. Research and development costs include staffing, purchases of materials and laboratory supplies, circuit design costs, fabrication and packaging of experimental display products, and overhead, and are expensed immediately.
	Cash and Equivalents and Marketable Securities
	The Company considers all highly liquid, short-term debt instruments with original maturities of three months or less to be cash equivalents.
	Marketable debt securities consist primarily of commercial paper, medium-term corporate notes, and United States government and agency backed securities. The Company classifies these marketable debt securities as available-for-sale at fair value in “Marketable debt securities, at fair value.” The investments in Vuzix Corporation (Vuzix) and GCS Holdings are included in "Other Assets" as available-for-sale and at fair value. The Company records the amortization of premium and accretion of discounts on marketable debt securities in the results of operations.
	The Company uses the specific identification method as a basis for determining cost and calculating realized gains and losses with respect to marketable debt securities. The gross gains and losses realized related to sales of marketable debt securities were not material during fiscal years 2014, 2013 and 2012.
	Inventory
	Inventory is stated at the lower of cost (determined on the first-in, first-out method) or market and consists of the following at December 27, 2014 and December 28, 2013:

		$	4,081,886			$	3,078,055
	Property, plant and equipment
	Property, plant and equipment are recorded at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the assets, generally 3 to 10 years. Leasehold improvements and leased equipment are amortized over the shorter of the term of the lease or the useful life of the improvement or equipment. As discussed below, obligations for asset retirement are accrued at the time property, plant and equipment is initially purchased or as such obligations are generated from use.
	Intangible assets
	At December 27, 2014 intangible assets consisted of patents. At December 28, 2013, intangible assets include patents, customer relationships, developed technology and trademarks. Customer relationships represent the fair value of the underlying relationships with customers. Developed technology represents the fair value of technology as it exists in current products and has value through its continued use or reuse. The trademark represents the brand and name recognition associated with the marketing of products and was determined to have a finite life.
	Identifiable intangible assets are amortized using the straight-line method over the estimated useful lives of the assets, generally three to seven years.
	Product Warranty
	The Company generally sells products with a limited warranty of product quality and a limited indemnification of customers against intellectual property infringement claims related to the Company’s products. The Company accrues for known warranty and indemnification issues if a loss is probable and can be reasonably estimated, and accrues for estimated incurred but unidentified issues based on historical activity. As of December 27, 2014 and December 28, 2013, the Company had warranty reserves of $0.7 million. For the fiscal years 2014, 2013 and 2012 warranty claims and reversals were approximately $0.4 million, $0.8 million and $2.2 million, respectively.
	Asset Retirement Obligations
	The Company recorded asset retirement obligations (ARO) liabilities of $0.3 million at December 27, 2014 and December 28, 2013, respectively. This represents the legal obligations associated with retirement of the Company’s assets when the timing and/or method of settling the obligation are conditional on a future event that may or may not be within the control of the Company.

	Income Taxes
	The consolidated financial statements reflect provisions for federal, state, local and foreign income taxes. The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, as well as operating loss and tax credit carryforwards. The Company measures deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company provides valuation allowances if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
	Foreign Currency
	Assets and liabilities of non-U.S. operations where the functional currency is other than the U.S. dollar are translated from the functional currency into U.S. dollars at year end exchange rates, and revenues and expenses at average rates prevailing during the year. Resulting translation adjustments are accumulated as part of accumulated other comprehensive income. Transaction gains or losses are recognized in income or loss in the period in which they occur.
	Net (Loss) Income Per Share
	Basic net (loss) income per share is computed using the weighted-average number of shares of common stock outstanding during the period less any unvested restricted shares. Diluted earnings per common share is calculated using weighted-average shares outstanding and contingently issuable shares, less weighted-average shares reacquired during the period. The net outstanding shares are adjusted for the dilutive effect of shares issuable upon the assumed conversion of the Company’s common stock equivalents, which consist of outstanding stock options and unvested restricted stock.
	Weighted-average common shares outstanding used to calculate earnings per share, is as follows:
		2014			2013			2012
	Weighted-average common shares outstanding—basic	62,638,675			62,347,852			63,617,680
	Stock options and nonvested restricted common stock	—			—			—
	Weighted-average common shares outstanding—diluted	62,638,675			62,347,852			63,617,680
	The following were not included in weighted-average common shares outstanding- diluted because they are anti-dilutive or performance conditions have not been met at the end of the period.
		2014			2013			2012
	Nonvested restricted common stock	2,551,631			3,024,148			2,283,048
	Stock options	130,500			558,850			983,680
	Total	2,682,131			3,582,998			3,266,728
	Not included in weighted average common shares outstanding-diluted are the warrants to purchase 200,000 shares of the
	Company’s common stock for $3.49 per share.
	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to concentration of credit risk other than marketable securities consist principally of trade accounts receivable and the note receivable from IQE, plc. Trade receivables are primarily derived from sales to manufacturers of consumer electronic devices and wireless components or military applications.
	The Company primarily invests its excess cash in government backed and corporate financial instruments that management believes to be of high credit worthiness, which bear lower levels of relative credit risk. The Company relies on rating agencies to ascertain the credit worthiness of its marketable securities and, where applicable, guarantees by the Federal Deposit Insurance Company. The Company sells its products to customers worldwide and generally does not require collateral. The Company maintains a reserve for potential credit losses.
	Fair Value of Financial Instruments
	Financial instruments consist of current assets (except inventories, income tax receivables and prepaid assets) and certain current liabilities. Current assets (excluding marketable securities which are recorded at fair value) and current liabilities are carried at cost, which approximates fair value.
	Stock-Based Compensation
	The fair value of stock option awards is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. There were no stock options granted in fiscal years 2014, 2013 or 2012.
The fair value of nonvested restricted common stock awards is generally the market value of the Company’s equity shares on the date of grant. The nonvested restricted common stock awards require the employee to fulfill certain obligations, including remaining employed by the Company for one, two or four years (the vesting period) and in certain cases also require meeting either performance criteria or the Company’s stock achieving a certain price. The performance criteria primarily consist of the achievement of established milestones. For nonvested restricted common stock awards which solely require the recipient to remain employed with the Company, the stock compensation expense is amortized over the anticipated service period. For nonvested restricted common stock awards which require the achievement of performance criteria, the Company reviews the probability of achieving the performance goals on a periodic basis. If the Company determines that it is probable that the performance criteria will be achieved, the amount of compensation cost derived for the performance goal is amortized over the service period. If the performance criteria are not met, no compensation cost is recognized and any previously recognized compensation cost is reversed. The Company recognizes compensation costs on a straight-line basis over the requisite service period for time vested awards.
In 2013, the Company granted compensation awards to its Chief Executive Officer that consisted of two grants of 150,000 shares of restricted stock each. One of the grants will vest at the end of the first 10 consecutive trading day period following the grant date during which the Company’s common stock trades at a price per share equal to or greater than $6.00. The other award will vest at the end of the first 10 consecutive trading day period following the grant date during which the Company’s common stock trades at a price per share equal to or greater than $7.00. In 2012, the Company granted compensation awards to its Chief Executive Officer that consisted of a grant of 260,000 shares of restricted stock and a grant of 380,000 shares of phantom stock to be settled in cash. The 260,000 shares of restricted stock and the 380,000 shares of phantom stock will vest at the end of the first 10 consecutive trading day period following the grant date during which the Company’s common stock trades at a price per share equal to or greater than $5.25, prior to September 12, 2016. The vesting of the awards upon achieving a closing stock price of $6.00, $7.00 and $5.25 for 10 consecutive days is considered a market condition. The accounting for the 150,000, 150,000 and 260,000 shares requires the fair market value of the shares to be determined on the grant day and then this fair market value is expensed straight-line over the derived service period. The accounting for the phantom stock award requires the Company to periodically assess the fair market value of the award, with increases or decreases in the fair market value being reflected in the statements of operations.
In 2013, the Company granted a compensation award to its Chief Executive Officer that consisted of a grant of 300,000 shares of restricted stock that will vest upon the Company shipping 50,000 units of a new display. The compensation cost of this award will be recognized over the period the Company ships the displays. As of December 27, 2014, these awards were not yet earned and no compensation expense has been recorded.
Comprehensive Loss
Comprehensive loss is the total of net (loss) income and all other non-owner changes in equity including such items as unrealized holding (losses) gains on marketable equity and debt securities classified as available-for-sale and foreign currency translation adjustments.
The components of accumulated other comprehensive income are as follows:
	Cumulative				Unrealized Holding			Accumulated Other

Balance as of December 27, 2014	$	1,534,075			$	1,592,164		$	3,126,239
Impairment of Long-Lived Assets
The Company periodically reviews the carrying value of its long-lived assets to determine if facts and circumstances suggest that they may be impaired or that the amortization or depreciation period may need to be changed. The carrying value of a long-lived asset is considered impaired when the anticipated identifiable undiscounted cash flows from such asset are less than its carrying value. For assets that are to be held and used, impairment is measured based upon the amount by which the carrying amount of the asset exceeds its fair value. The carrying value of the Company’s long-lived assets was $4.6 million at December 27, 2014.
Recently Issued Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606). The reporting standard requires the Company to identify the performance obligations in a contract, determine the transaction price, allocate the transaction price to each of the obligations and then recognizes the transaction price as the obligations are fulfilled. The standard also requires certain new disclosures. The standard is effective for annual and interim reporting periods beginning after December 15, 2016. The Company is currently assessing the potential impact of the adoption of ASU 2014-09 on its consolidated financial statements.
Statement of Comprehensive Income
During the twelve months ended December 27, 2014, the change in the Company's accumulated other comprehensive income was the net of $(1.1) million cumulative translation adjustment and $0.7 million unrealized holding gains on marketable securities.

	Fair Value Measurements
	Under accounting guidance, financial instruments are categorized as Level 1, Level 2 or Level 3 based upon the method by which their fair value is computed. An investment is categorized as Level 1 when its fair value is based on unadjusted quoted prices in active markets for identical assets that the Company has the ability to access at the measurement date. An investment is categorized as Level 2 if its fair market value is based on quoted market prices for similar assets in active markets, quoted prices for identical or similar assets in markets that are not active, based on observable inputs such as interest rates, yield curves, or derived from or corroborated by observable market data by correlation or other means. An investment is categorized as Level 3 if its fair value is based on assumptions developed by the Company about what a market participant would use in pricing the assets.
	The Company’s investments are either held by brokers or in the case of publicly-held corporation, by the Company. The brokers who hold the Company’s investments provide periodic reporting on both the cost and fair value of the securities. The Company performs various procedures to corroborate the fair value provided by the brokers. Debt securities reflected in the table below include investments such as certificates of deposit, commercial paper, corporate bonds, government bonds, and money market fund deposits. When the Company uses observable market prices for identical securities that are traded in less active markets, its debt investments are classified as Level 2. When observable market prices for identical securities are not available, the Company prices our debt investments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models, such as a discounted cash flow model, with all significant inputs derived from or corroborated with observable market data. Non-binding market consensus prices are based on quotes from brokers. The discounted cash flow model uses observable market inputs, such as US treasury-based yield curves.
	The following table details the fair value measurements within the fair value hierarchy of the Company’s financial assets:

	The corporate debt consists of floating rate notes with a maturity that is over multiple years but has interest rates which are reset every three months based on the then current three month London Interbank Offering Rate (3 month Libor). The Company determines the fair market values of these corporate debt instruments through the use of a model which incorporates the 3 month Libor, the credit default swap rate of the issuer and the bid and ask price spread of same or similar investments which are traded on several markets.
	The carrying amounts of cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value because of their short term nature. The carrying amount of accrued liabilities is classified as Level 2 in the fair value hierarchy.

	The Company reviews its marketable debt securities on a quarterly basis for the presence of other-than-temporary impairment (OTTI).
	If the Company determines that an OTTI has occurred it further estimates the amount of OTTI resulting from a decline in the credit worthiness of the issuer (credit-related OTTI) and the amount of non credit-related OTTI. Noncredit-related OTTI can be caused by such factors as market illiquidity. Credit-related OTTI is recognized in earnings while noncredit-related OTTI on securities not expected to be sold is recognized in other comprehensive income (OCI). The Company did not record any OTTI for the fiscal years 2014, 2013 and 2012.

Stockholders' Equity and Stock-Based Compensation	Stockholders’ Equity and Stock-Based Compensation
	In March 2013, the Company’s Board of Directors authorized the repurchase of up to $30 million of the Company’s common stock in open market or negotiated transactions through March 2014. Since the plan’s inception through December 27, 2014, the Company has purchased 2,241,121 shares of its common stock for $8,290,573.
	The Company has stock-based awards outstanding under two plans. In 2001, the Company adopted a 2001 Equity Incentive Plan (the Equity Plan). The Equity Plan authorized 7,100,000 shares of common stock, to be issued to employees, non-employees, and members of the Board of Directors (the Board). The Equity Plan had a ten year life and therefore no new equity awards may be issued under this plan. In 2010, the Company adopted a 2010 Equity Incentive Plan (the 2010 Equity Plan) which authorized the issuance of shares of common stock to employees, non-employees, and the Board. The 2010 Equity Plan has been subsequently amended to increase the number of authorized shares. The number of shares authorized is 500,000 plus the number of shares of common stock which were available for grant under the Equity Plan, the number of shares of common stock which were the subject of awards outstanding under the Equity Plan and are forfeited, terminated, canceled or expire after the adoption of the 2010 Equity Plan and the number of shares of common stock delivered to the Company either in exercise of an Equity Plan award or in satisfaction of a tax withholding obligation. The option price of statutory incentive stock options shall not be less than 100% of the fair market value of the stock at the date of grant, or in the case of certain statutory incentive stock options, at 110% of the fair market value at the time of the grant. The option price of nonqualified stock options is determined by the Board or Compensation Committee. Options must be exercised within a ten-year period or sooner if so specified within the option agreement. The term and vesting period for restricted stock awards and options granted under the 2010 Equity Plan are determined by the Board’s compensation committee.
	During the six months ended June 28, 2014, the 2010 Equity Plan was amended to increase the number of authorized shares by 1.9 million. The Company has available approximately 3.0 million shares of common stock available for issuance under the Company’s 2010 Equity Plan in excess of shares of common stock which have already been reserved for under previously issued equity awards.
	Stock Options
	A summary of stock option activity under the stock award plans as of December 27, 2014 and changes during the twelve month period is as follows:
		2014
		Shares		Weighted
				Average
				Exercise
				Price
	Balance, beginning of year	558,850		$	5.09

	Options exercised	(36,750	)	3.75
	Balance, end of year	130,500		$	3.49
	Exercisable, end of year	130,500
	The Company has 130,500 stock options outstanding at December 27, 2014 which will expire by May 19, 2015 and have exercise prices that range from $3.15 to $3.87. The aggregate intrinsic value of the options at December 27, 2014 was approximately $13,000. No stock options were issued in 2014, 2013 or 2012. The intrinsic value of options exercised in 2014, 2013 and 2012 was approximately $26,000, $0 and $0, respectively. The Company has issued warrants to purchase 200,000 shares of the Company’s stock at $3.49. During the year ended December 29, 2012, the warrants became fully vested.
	Cash received from option exercises under all share-based payment arrangements was approximately $0.1 million for fiscal year 2014. No tax benefits were realized during the three year period ended 2014 due to the existence of tax net operating loss carryforwards.
	NonVested Restricted Common Stock
	The Company has issued shares of nonvested restricted common stock to certain employees. Each award requires the employee to fulfill certain obligations, including remaining employed by the Company for one, two or four years (the vesting period) and in certain cases also meeting performance criteria. A summary of the activity for nonvested restricted common stock awards as of December 27, 2014 and changes during the twelve months then ended is presented below:
		Shares		Weighted
				Average
				Grant
				Fair Value
	Balance, December 28, 2013	2,974,148		$	4.25
	Granted	523,000		4.01
	Forfeited	(102,400	)	3.33
	Vested	(843,117	)	3.73
	Balance, December 27, 2014	2,551,631		$	4.41
	Included within the nonvested restricted common stock table above is 50,000 awards granted for which the performance conditions have yet to be determined and therefore a grant date has not yet been established for the award.  No stock based compensation expense has been recorded relating to this award during the three and twelve month period ended December 27, 2014.
	The forfeitures in 2014 were primarily due to fact that the performance criteria were not met related to these awards.
	Stock-Based Compensation
	The following table summarizes stock-based compensation expense related to employee stock options and nonvested restricted common stock awards for the fiscal years 2014, 2013 and 2012 (no tax benefits were recognized):
		2014			2013		2012
	Cost of component revenues	$	766,221		$	414,842	$	513,789

	Total	$	4,827,772		$	4,203,408	$	4,486,990
	Total unrecognized compensation expense for the nonvested restricted common stock as of December 27, 2014 totals $3.5 million and is expected to be recognized over a period of two years.

	The benefit for income taxes for the fiscal year ended 2014 of $0.2 million represents the net of state and foreign withholding tax.
	Deferred income taxes are provided to recognize the effect of temporary differences between tax and financial reporting. Deferred income tax assets and liabilities consist of the following:

	As of December 27, 2014, the Company has available for tax purposes federal net operating loss carryforwards (NOLs) of $65.0 million expiring through 2033. The Company has recognized a full valuation allowance on its net deferred tax assets as the Company has concluded that such assets are not more likely than not to be realized. The $10.6 million increase in valuation allowance during fiscal year 2014 was primarily due to an increase in net operating loss carryforwards. The 3.7 million increase in valuation allowance during fiscal year 2013 was primarily due to net operating losses generated of $8.6 million and the sale of III-V assets. The Company has not historically recorded, nor does it intend to record the tax benefits from stock awards until realized. Unrecorded benefits from stock awards approximated $10.3 million at December 27, 2014.
	The Company has suspended operations and terminated the majority of employees at its Korean subsidiary, Kowon. The assets, primarily buildings and land, have been put up for sale. It is more likely than not that the Company's share of the net book value of its Korean investment would be repatriated to the U.S. resulting in a Korean withholding tax of $1.3 million. As a result of the Company no longer being permanently reinvested in Korea, a deferred tax liability for the unremitted earnings in the Korean subsidiary has been booked for $2.9 million.
	In September 2013, the U.S. Department of the Treasury and the Internal Revenue Service released final regulations relating to guidance on applying tax rules to amounts paid to acquire, produce or improve tangible personal property as well as rules for materials and supplies. The Company is currently assessing these rules and the impacts to the financial statements, if any.
	The Company’s income tax returns have not been examined by the Internal Revenue Service and are subject to examination for all years since 2001. State income tax returns are generally subject to examination for a period of three to five years after filing of the respective return. The state impact of any federal changes remains subject to examination by various states for a period of up to one year after formal notification to the states.
	International jurisdictions have statutes of limitations generally ranging from three to seven years after filing of the respective return. Years still open to examination by tax authorities in major jurisdictions include Korea (2006 onward), Japan (2006 onward), Hong Kong (2008 onward) and United Kingdom (2011 onward). The Company is not currently under examination in these jurisdictions.

During the year ended December 28, 2013, the Company transferred the manufacturing operations of Kowon to the Company's manufacturing facility in the United States and sold its III-V product line including its investment in KTC. As a result of these transactions, the Company has reorganized its operations to align with its new strategy to primarily focus on developing its wearable computing systems and its reflective display products. Accordingly, the Company has determined it has two reportable segments, FDD, the manufacturer of its reflective display products for test and simulation products, and Kopin, which is comprised of Kopin Corporation, Kowon, Intoware and eMDT.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 27, 2014
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, a majority owned 93% subsidiary, Kowon Technology Co., Ltd. (Kowon), located in Korea, a majority owned 58% subsidiary, Intoware Ltd. (Intoware), located in the United Kingdom, (formerly known as Ikanos Consulting Limited) and a majority owned 80% subsidiary, eMDT America Inc (eMDT), located in California (collectively the Company). All intercompany transactions and balances have been eliminated. Amounts of Kowon, Intoware and eMDT not attributable to the Company are referred to as noncontrolling interests in the consolidated statements of operations and consolidated statements of comprehensive loss. Investments in business entities in which the Company does not have control but has the ability to exercise significant influence over operating and financial policies are accounted for by the equity method.
	In 2013, the Company paid approximately $3.7 million to acquire an additional 15% ownership in its Kowon subsidiary which raised its ownership from 78% to 93%. The Company ceased its production activities at its Kowon facility in 2013 but as of December 27, 2014, the closure of this facility did not meet the criteria for assets held for sale.
Revenue Recognition	Revenue Recognition
	The Company recognizes revenue if four basic criteria have been met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred and services rendered; (3) the price to the buyer is fixed or determinable; and (4) collectability is reasonably assured. The Company does not recognize revenue for products prior to customer acceptance unless it believes the product meets all customer specifications and the Company has a history of consistently achieving customer acceptance of the product. Provisions for product returns and allowances are recorded in the same period as the related revenues. The Company analyzes historical returns, current economic trends and changes in customer demand and acceptance of product when evaluating the adequacy of sales returns and other allowances. Certain product sales are made to distributors under agreements allowing for a limited right of return on unsold products. Sales to distributors are primarily made for sales to the distributors' customers and not for their stocking of inventory. The Company delays revenue recognition for its estimate of distributor claims of right of return on unsold products based upon its historical experience with the Company’s products and specific analysis of amounts subject to return based upon discussions with the Company’s distributors or their customers.
	The Company recognizes revenues from long-term research and development contracts on the percentage-of-completion method of accounting as work is performed, based upon the ratio of costs or hours already incurred to the estimated total cost of completion or hours of work to be performed. Revenue recognized at any point in time is limited to the amount funded by the U.S. government or contracting entity. The Company accounts for product development and research contracts that have established prices for distinct phases as if each phase were a separate contract. In some instances, the Company is contracted to create a deliverable which is anticipated to be qualified and go into full rate production stages. In those cases, the revenue recognition methodology will change from the percentage of completion method to the units-of-delivery method as new contracts are received after formal qualification has been completed. Under certain of its research and development contracts, the Company recognizes revenue on a milestone methodology.  This revenue is recognized when the Company achieves specified milestones based on its past performance.
	The Company classifies amounts earned on contracts in progress that are in excess of amounts billed as unbilled receivables and classifies amounts received in excess of amounts earned as billings in excess of revenues earned. The Company invoices based on dates specified in the related agreement or in periodic installments based upon its invoicing cycle. The Company recognizes the entire amount of an estimated ultimate loss in its financial statements at the time the loss on a contract becomes known.
Research and Development Costs	Research and Development Costs
	Research and development expenses are incurred in support of internal display product development programs or programs funded by agencies or prime contractors of the U.S. government and commercial partners. Research and development costs include staffing, purchases of materials and laboratory supplies, circuit design costs, fabrication and packaging of experimental display products, and overhead, and are expensed immediately.
Cash and Cash Equivalents	Cash and Equivalents and Marketable Securities
	The Company considers all highly liquid, short-term debt instruments with original maturities of three months or less to be cash equivalents.
Marketable Securities	Marketable debt securities consist primarily of commercial paper, medium-term corporate notes, and United States government and agency backed securities. The Company classifies these marketable debt securities as available-for-sale at fair value in “Marketable debt securities, at fair value.” The investments in Vuzix Corporation (Vuzix) and GCS Holdings are included in "Other Assets" as available-for-sale and at fair value. The Company records the amortization of premium and accretion of discounts on marketable debt securities in the results of operations.
	The Company uses the specific identification method as a basis for determining cost and calculating realized gains and losses with respect to marketable debt securities. The gross gains and losses realized related to sales of marketable debt securities were not material during fiscal years 2014, 2013 and 2012
Inventory	Inventory
	Inventory is stated at the lower of cost (determined on the first-in, first-out method) or market and consists of the following at December 27, 2014 and December 28, 2013:
		2014				2013
	Raw materials	$	2,057,202			$	1,441,569
	Work-in-process	1,551,799				1,003,540
	Finished goods	472,885				632,946
		$	4,081,886			$	3,078,055
Property, Plant and Equipment	Property, plant and equipment
	Property, plant and equipment are recorded at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the assets, generally 3 to 10 years. Leasehold improvements and leased equipment are amortized over the shorter of the term of the lease or the useful life of the improvement or equipment. As discussed below, obligations for asset retirement are accrued at the time property, plant and equipment is initially purchased or as such obligations are generated from use.
Intangible Assets	Intangible assets
	At December 27, 2014 intangible assets consisted of patents. At December 28, 2013, intangible assets include patents, customer relationships, developed technology and trademarks. Customer relationships represent the fair value of the underlying relationships with customers. Developed technology represents the fair value of technology as it exists in current products and has value through its continued use or reuse. The trademark represents the brand and name recognition associated with the marketing of products and was determined to have a finite life.
	Identifiable intangible assets are amortized using the straight-line method over the estimated useful lives of the assets, generally three to seven years.
Product Warranty	Product Warranty
	The Company generally sells products with a limited warranty of product quality and a limited indemnification of customers against intellectual property infringement claims related to the Company’s products. The Company accrues for known warranty and indemnification issues if a loss is probable and can be reasonably estimated, and accrues for estimated incurred but unidentified issues based on historical activity. As of December 27, 2014 and December 28, 2013, the Company had warranty reserves of $0.7 million. For the fiscal years 2014, 2013 and 2012 warranty claims and reversals were approximately $0.4 million, $0.8 million and $2.2 million, respectively.
Asset Retirement Obligations	Asset Retirement Obligations
	The Company recorded asset retirement obligations (ARO) liabilities of $0.3 million at December 27, 2014 and December 28, 2013, respectively. This represents the legal obligations associated with retirement of the Company’s assets when the timing and/or method of settling the obligation are conditional on a future event that may or may not be within the control of the Company.
		2014				2013
	Beginning balance	$	329,435			$	322,477
	Additions	—				—
	Charges	—				—
	Accretion and exchange rate change	(18,248		)		6,958
	Ending balance	$	311,187			$	329,435
Income Taxes	Income Taxes
	The consolidated financial statements reflect provisions for federal, state, local and foreign income taxes. The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, as well as operating loss and tax credit carryforwards. The Company measures deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company provides valuation allowances if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
Foreign Currency	Foreign Currency
	Assets and liabilities of non-U.S. operations where the functional currency is other than the U.S. dollar are translated from the functional currency into U.S. dollars at year end exchange rates, and revenues and expenses at average rates prevailing during the year. Resulting translation adjustments are accumulated as part of accumulated other comprehensive income. Transaction gains or losses are recognized in income or loss in the period in which they occur.
Net (Loss) Income Per Share	Net (Loss) Income Per Share
	Basic net (loss) income per share is computed using the weighted-average number of shares of common stock outstanding during the period less any unvested restricted shares. Diluted earnings per common share is calculated using weighted-average shares outstanding and contingently issuable shares, less weighted-average shares reacquired during the period. The net outstanding shares are adjusted for the dilutive effect of shares issuable upon the assumed conversion of the Company’s common stock equivalents, which consist of outstanding stock options and unvested restricted stock.
	Weighted-average common shares outstanding used to calculate earnings per share, is as follows:
		2014			2013			2012
	Weighted-average common shares outstanding—basic	62,638,675			62,347,852			63,617,680
	Stock options and nonvested restricted common stock	—			—			—
	Weighted-average common shares outstanding—diluted	62,638,675			62,347,852			63,617,680
	The following were not included in weighted-average common shares outstanding- diluted because they are anti-dilutive or performance conditions have not been met at the end of the period.
		2014			2013			2012
	Nonvested restricted common stock	2,551,631			3,024,148			2,283,048
	Stock options	130,500			558,850			983,680
	Total	2,682,131			3,582,998			3,266,728
	Not included in weighted average common shares outstanding-diluted are the warrants to purchase 200,000 shares of the
	Company’s common stock for $3.49 per share.
Concentration of Credit Risk	Concentration of Credit Risk
	Financial instruments that potentially subject the Company to concentration of credit risk other than marketable securities consist principally of trade accounts receivable and the note receivable from IQE, plc. Trade receivables are primarily derived from sales to manufacturers of consumer electronic devices and wireless components or military applications.
	The Company primarily invests its excess cash in government backed and corporate financial instruments that management believes to be of high credit worthiness, which bear lower levels of relative credit risk. The Company relies on rating agencies to ascertain the credit worthiness of its marketable securities and, where applicable, guarantees by the Federal Deposit Insurance Company. The Company sells its products to customers worldwide and generally does not require collateral. The Company maintains a reserve for potential credit losses.
Fair Value of Financial Instruments	Fair Value of Financial Instruments
	Financial instruments consist of current assets (except inventories, income tax receivables and prepaid assets) and certain current liabilities. Current assets (excluding marketable securities which are recorded at fair value) and current liabilities are carried at cost, which approximates fair value.
Stock-Based Compensation	Stock-Based Compensation
	The fair value of stock option awards is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. There were no stock options granted in fiscal years 2014, 2013 or 2012.
	The fair value of nonvested restricted common stock awards is generally the market value of the Company’s equity shares on the date of grant. The nonvested restricted common stock awards require the employee to fulfill certain obligations, including remaining employed by the Company for one, two or four years (the vesting period) and in certain cases also require meeting either performance criteria or the Company’s stock achieving a certain price. The performance criteria primarily consist of the achievement of established milestones. For nonvested restricted common stock awards which solely require the recipient to remain employed with the Company, the stock compensation expense is amortized over the anticipated service period. For nonvested restricted common stock awards which require the achievement of performance criteria, the Company reviews the probability of achieving the performance goals on a periodic basis. If the Company determines that it is probable that the performance criteria will be achieved, the amount of compensation cost derived for the performance goal is amortized over the service period. If the performance criteria are not met, no compensation cost is recognized and any previously recognized compensation cost is reversed. The Company recognizes compensation costs on a straight-line basis over the requisite service period for time vested awards.
	In 2013, the Company granted compensation awards to its Chief Executive Officer that consisted of two grants of 150,000 shares of restricted stock each. One of the grants will vest at the end of the first 10 consecutive trading day period following the grant date during which the Company’s common stock trades at a price per share equal to or greater than $6.00. The other award will vest at the end of the first 10 consecutive trading day period following the grant date during which the Company’s common stock trades at a price per share equal to or greater than $7.00. In 2012, the Company granted compensation awards to its Chief Executive Officer that consisted of a grant of 260,000 shares of restricted stock and a grant of 380,000 shares of phantom stock to be settled in cash. The 260,000 shares of restricted stock and the 380,000 shares of phantom stock will vest at the end of the first 10 consecutive trading day period following the grant date during which the Company’s common stock trades at a price per share equal to or greater than $5.25, prior to September 12, 2016. The vesting of the awards upon achieving a closing stock price of $6.00, $7.00 and $5.25 for 10 consecutive days is considered a market condition. The accounting for the 150,000, 150,000 and 260,000 shares requires the fair market value of the shares to be determined on the grant day and then this fair market value is expensed straight-line over the derived service period. The accounting for the phantom stock award requires the Company to periodically assess the fair market value of the award, with increases or decreases in the fair market value being reflected in the statements of operations.
	In 2013, the Company granted a compensation award to its Chief Executive Officer that consisted of a grant of 300,000 shares of restricted stock that will vest upon the Company shipping 50,000 units of a new display. The compensation cost of this award will be recognized over the period the Company ships the displays. As of December 27, 2014, these awards were not yet earned and no compensation expense has been recorded.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Loss
	Comprehensive loss is the total of net (loss) income and all other non-owner changes in equity including such items as unrealized holding (losses) gains on marketable equity and debt securities classified as available-for-sale and foreign currency translation adjustments.
	The components of accumulated other comprehensive income are as follows:
		Cumulative				Unrealized Holding			Accumulated Other
		Translation				Gain (Loss) on			Comprehensive
		Adjustment				Marketable			Income
						Securities
	Balance as of December 31, 2011	$	1,319,870			$	2,826,154		$	4,146,024
	Changes during year	2,222,234				144,534			2,366,768
	Balance as of December 29, 2012	3,542,104				2,970,688			6,512,792
	Changes during year	(1,017,403		)		(2,053,392		)	(3,070,795		)
	Balance as of December 28, 2013	2,524,701				917,296			3,441,997
	Changes during year	(990,626		)		674,868			(315,758		)
	Balance as of December 27, 2014	$	1,534,075			$	1,592,164		$	3,126,239
Impairment Long-Lived Assets	Impairment of Long-Lived Assets
	The Company periodically reviews the carrying value of its long-lived assets to determine if facts and circumstances suggest that they may be impaired or that the amortization or depreciation period may need to be changed. The carrying value of a long-lived asset is considered impaired when the anticipated identifiable undiscounted cash flows from such asset are less than its carrying value. For assets that are to be held and used, impairment is measured based upon the amount by which the carrying amount of the asset exceeds its fair value. The carrying value of the Company’s long-lived assets was $4.6 million at December 27, 2014.
Recently Adopted Accounting Pronouncements	Recently Issued Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606). The reporting standard requires the Company to identify the performance obligations in a contract, determine the transaction price, allocate the transaction price to each of the obligations and then recognizes the transaction price as the obligations are fulfilled. The standard also requires certain new disclosures. The standard is effective for annual and interim reporting periods beginning after December 15, 2016. The Company is currently assessing the potential impact of the adoption of ASU 2014-09 on its consolidated financial statements.
	Statement of Comprehensive Income
	During the twelve months ended December 27, 2014, the change in the Company's accumulated other comprehensive income was the net of $(1.1) million cumulative translation adjustment and $0.7 million unrealized holding gains on marketable securities.
