Abstract

A 6-b digital source driver has been developed. CA (computer application) TFT-LCD (thin-film transistor liquid crystal display) panels driven by this driver can simultaneously display 6-b (64 gray level) images with 262144 colors. A system has been developed that can produce both CA and AV (audio-visual) images by compressing 8-b video data into 6-b data using the interframe modulation method. This study has demonstrated success in developing technology that can generate natural color on a CA TFT-LCD display. Through this technology, it has been shown that conventional CA and AV panel functions can be combined in a single CA-type display.<>
