1-billion-color TFT LCD TV with full HD format

To develop data driver LSIs for over a 1-billion-color TFT-LCD TV with full HD (1920/spl times/1080) format, key issues in the driver architecture as well as circuit design and TFT-LCD panel issues for realizing true 1024 gray level images are discussed. We present our recent results of the 10-bit gray scale TFT-LCD data driver applied to 42-inch diagonal 1-billion-color TFT-LCD TV with full HD format. We verified that the picture with 10-bit shades of gray is much more natural than that with 8-bit shades of gray.
