A low power (lower than 50mW) and high resolution (332ppi) VGA LCD with integrated 6‐bit digital data drivers has been developed using CLC (CW‐Laser Lateral Crystallization) technology. Logic operations at 3V and low power analog buffer circuits are realized by improved uniformity of TFT characteristics. Integration of digital drivers with line‐at‐a‐time driving scheme is achieved by fine lithography technology (2μm pitch wiring).
