Abstract
Abstract—We have developed a 6‐bit D/A converter and amplifier integrated low‐temperature poly‐Si TFT‐LCD in which an integrated signal‐line driver is driven by a 5‐V power supply. We have employed a D/A converter including a new capacitor array and an original amplifier comprised of serially connected comparators to achieve high accuracy. The D/A converter performs gamma correction using upper significant bits of input data. Control signals for these circuits were generated by the integrated timing circuit. These advances in integration have been achieved for the first time using 3‐μm design rule and improved LTPS TFT technologies and provide an advanced display system with lower power consumption, smaller module size, and higher durability.
