Abstract
A method of generating frame control signals for reducing reaction time comprises following steps: analyzing an input frame signal; generating a first reference liquid crystal control signal of a frame; setting a second liquid crystal control signal range and thereby generating a second reference liquid crystal control signal; generating a second backlight control signal according to the first reference liquid crystal control signal and the second reference liquid crystal control signal; and generating a second liquid crystal control signal of each pixel according to the second backlight control signal. By confining the second backlight control signal to the second liquid crystal control signal range, the reaction time of the liquid crystals is reduced and the frame quality of LCD devices is enhanced.
