OKI Enhances Lineup of High Performance Driver LSIs for Full High-definition LCD TVs
Volume production to follow for three new products with High-speed drive, multi gray-scales and low heat generation
Tokyo, Japan, May 21, 2007 -- Oki Electric Industry Co., Ltd. (TSE: 6703) today announced it will enhance its product lineup for high-performance LSIs used in full high-definition(*1) LCD TVs. The three new driver LSIs, MT3126, MT3131, and MT3139, all include features with high-speed drive, multi gray-scales and low heat generation. The models will be shipped in sequence from May 2007.
"With this new series, full high-definition LCD TVs can be compliant to advanced technologies, enabling higher quality TVs," said Takaki Yamada, President of Silicon Microdevice Company at Oki Electric Industry. "We will provide these three models that achieve high-speed drive, multi gray-scales and low heat generation worldwide from May 2007 in sequence. Our aim is to increase our share in the driver LSI market for LCD TVs."
The three models announced today feature drive speed that is doubled from 60Hz, the speed used for conventional W-XGA(*2) LCD TVs, to 120Hz, thus improving the response time of LCD pixels. The shift from conventional 8bit multi gray-scales (for 16 million color display) is expected to improve to 10bit multi gray-scales (for 1 billion color display) for more precise color display. What is more, OKI succeeded in enabling this 10bit multi gray-scales without a large cost increase, by using a newly developed DAC (digital to analog converter) circuit. In addition, using its own unique circuit technology, OKI was able to reduce heat generation by 35% thus eliminating the heat issue in the driver LSIs as LCD TVs become larger and faster.
