               TRIDENT MICROSYSTEMS REPORTS FINANCIAL RESULTS FOR
                       SECOND QUARTER OF FISCAL YEAR 2004

Sunnyvale, Calif, --- January 22, 2004: Trident Microsystems, Inc. (NASDAQ:
TRID) reported today its financial results for the second quarter of fiscal year
2004 ended December 31, 2003. The Company announced that its net sales for the
second quarter, primarily contributed by TTI, an 83% owned subsidiary, were
$16,227,000, an increase of 65% from $9,832,000 for the prior quarter and an
increase of 22% from $13,283,000 for the same quarter of the prior fiscal year.
The year ago period included sales of graphics products, which have been
discontinued. $15,889,000 of net sales for the quarter ended December 31, 2003
were primarily from digital media sales, this compares to digital media sales
for the prior quarter of $9,209,000, an increase of 73%, and digital media sales
for the same quarter of the prior fiscal year of $7,157,000, an increase of
122%. Trident's revenue includes 100% of the revenue of TTI, and an adjustment
is made for the minority interest in TTI before calculation of earnings and
earnings per TMI share.

Net income in the second quarter of fiscal year 2004 after taking into account
minority ownership of TTI was $1,432,000, or $0.06 per diluted share after a
three-for-two stock split on December 12, 2003. This compares to a net income
$4,679,000, or $0.19 per diluted share in the prior quarter, which includes a
pre-tax gain of $7.6 million related to the restructuring of the Graphics
Division and to the sales of 6.8% of the equity of our subsidiary, TTI, and of
one-third of our interest of XGI stock, and a net loss $6,802,000 or $0.33 for
the same quarter of the prior fiscal year. Per share amounts have been adjusted
to reflect the recent three-for-two stock split.

"Although I am pleased with the December quarter results, the results were a
mixed blessing. We exceeded our expectations for the December quarter, which was
forecasted to grow 25-35% over the prior quarter. The additional growth was
stronger due in part to China's TV makers requiring early delivery to meet
demand for a Chinese New Year that falls earlier this year than normal. We
believe this will skew our quarter over quarter results. We have always expected
seasonality in our March quarter but with the strength of the December quarter,
we are certain the March quarter will be a down quarter. However, we believe
that revenue will meet or exceed market expectations," said Frank Lin, Trident's
President and CEO.

"Second quarter revenue for TTI was $15.9M million. This represents an increase
of 73% over the prior quarter. During the second quarter, revenues from our
LCDTV and PDP products more than doubled, exceeding our projections, and the
progressive CRT TV business in China also experienced stronger demand than our
original expectation. In the second quarter, progressive CRT TV revenue grew
55%, and LCDTV and PDP revenue grew 137%. The CRT TV revenue now accounts for
61% of the total revenue as compared with 68% in the first quarter, and the
LCDTV and PDP revenue accounts for

37% of the total revenue as compared with 27% in the first quarter," said JH
Chang, President of TTI. "Due to an earlier Chinese New Year which is January 22
in 2004 versus early February as in typical years, China TV manufacturers have
pulled in some of their orders from January to December. During the December
quarter, we announced our new HiDTV product line for the emerging HDTV market.
We believe this is the industry's first SoC chip to fully integrate HDTV
audio/video decoding, analog video processing and TV features/ requirements all
into a single chip. We showcased a fully functional HiDTV prototype in the
Consumer Electronics Show (CES) in Las Vegas two weeks ago. The full-featured
HiDTV product demonstration was very successful and had received very
enthusiastic responses from many TV OEM customers worldwide. We believe our
HiDTV chip, with the highest integration level and the best quality, will be a
very competitive and winning product for the HDTV market. The HiDTV chip is
expected to start bringing in revenue in the second half of the calendar year
2004. During the December quarter, we announced additional DPTV design wins at
Sampo and Daewoo Electronics. Recently, we also announced DPTV design-wins at
Konka and Samsung Electronics. It demonstrates that our DPTV design win momentum
continues strong especially for the new DPTV-SVP product. We hope we can
announce more top-tier OEM design wins in the near future."

The Company also announced that it will hold a conference call to discuss the
earnings, which will occur on Thursday, January 22, 2004 at 2:30 p.m. Pacific
