30.1: A 6-bit-Color VGA Low-Temperature Poly-Si TFT-LCD with Integrated Digital Data Drivers

A 4.7-in. VGA low temperature poly-Si TFT-LCD with integrated a 6-bit digital data driver has been developed. New SC-DAC with γ-compensation function has realized a good gray scale and very low power consumption. We have succeeded in realizing a full digital interface with TTL level in the TFT driver to a conventional VGA controller for the first time.
