Line inversion-based mobile TFT-LCD driver IC with accurate quadruple-gamma-curve correction

Line inversion-based mobile TFT-LCD driver IC with novel quadruple-gamma-curve correction is presented. The driver IC allows for a cost-effective accurate curve correction for multiple gamma values of ??1.0, ??1.8, ??2.2, and ??2.5 by adopting novel voltage-symmetric gray curve synthesis and variable reference resistor-tap biasing schemes. A test chip in a 6 V/0.7-??m triple-well CMOS process indicated a gray voltage error of ??8 mV with gray-to-gray error difference under ??3 mV
