Abstract

Disclosed herein is a stepwise-voltage compensated driving method for vertical aligned LCD, where applied voltage for Blue (B), Green (G), Red (R) color is set to different amplitude and slicing step of gray level. This driving method is optimized for a normally black (NB) vertical aligned color LCD, which has different T-V (transmittance-voltage) curve for each B, G, R color. Steep-ness of each color is different and Blue is the steepest, Green is next, and Red is the slowest.
