LIQUID CRYSTAL DISPLAYS WITH SEQUENTIAL DRIVE SCHEMES

摘要

A method of driving a liquid crystal display pixel comprises (i) driving the pixel to a reference state (30a, 32a, 34a) , (ii) driving the pixel to a first overdrive voltage derived from a desired pixel drive level (30b, 32b, 34b) , (in) driving the pixel to a second voltage derived from the desired pixel drive level (30c, 32c, 34c) ; and (iv) illuminating the pixel using a backlight (R, G, B) . These steps are repeated a plurality of times for each colour addressing operation, each repetition comprising an addressing phase. The illumination uses a different backlight colour output for each phase (30, 32, 34) .
