Exhibit 99.1
               TRIDENT MICROSYSTEMS REPORTS FINANCIAL RESULTS FOR
                        THIRD QUARTER OF FISCAL YEAR 2003

Sunnyvale, Calif. --- April 22, 2003: Trident Microsystems, Inc. (NASDAQ:
TRID-news) reported today its financial results for the third quarter of fiscal
year 2003 which ended March 31, 2003. The Company announced that its net sales
for the third quarter were $11,614,000, a decrease of 13% from the $13,283,000
for the prior quarter and a decrease of 60% from $28,839,000 for the same
quarter of the prior fiscal year. The net loss for the third quarter of fiscal
year 2003 was $7,543,000 or $0.55 per share compared to a net loss of
$6,802,000, or $0.50 per share for the prior quarter and a net loss of
$2,076,000, or $0.15 per share for the same quarter of the prior fiscal year.
Included in the net loss for the third quarter of fiscal year 2003 was
$2,821,000 in loss on investments. The operating loss for the third quarter,
which excludes this loss on investments, was $4,264,000.

"Our graphics revenue for the March quarter remained disappointing as we had
expected. During the past year our graphics business has declined as a result of
execution delays in new product introduction, missed design win cycles as well
as rapid PC platform transition from Intel Pentium-3 to Pentium-4 processors,"
said Mr. Frank Lin, Trident's President and CEO. "Going forward, we remain
cautious and do not expect our graphics revenue to improve over the next few
quarters. The Board and management are also actively reviewing alternatives for
improving operations as well as other strategic alternatives for the Company."

"For our Digital Media Business Unit, we are glad to report strong revenue of
$7.0 million for the DPTV product line for the March quarter, an increase of 3%
from $6.8 million for the prior quarter. In this quarter we saw more significant
growth in the Taiwan (69% growth) and Korea (41% growth) markets, but
experienced some seasonal slowdown in the China market. The Taiwan and Korea
markets now account for about 39% of total DPTV revenue. Overall, we continue
our strong efforts in building up our worldwide market positions in
CRT-progressive TVs, Projection TVs, LCD TVs, Plasma TVs, and TV Boxes. The
DPTV-powered TV products from industry leaders such as Projection TV from
Changhong, LCD TVs from Samsung, Plasma TVs from Sampo, TV Boxes from ViewSonic,
etc. continue to be strong in their individual market segments. More
significantly the new generation of DPTV-family, DPTV(TM)3DPRO, which delivers
cinema-realistic motion and still images for high-performance LCD, Projection,
and Plasma TVs is now in mass production. This product further solidifies our
leadership position in the digital video processing market. For the June
quarter, we expect to see a similar flat quarter for the Digital Media Business
Unit due to a seasonal slowdown in China. However, we anticipate our DPTV
revenue will resume its strong growth in the second half of calendar year 2003."
