SIDE-EDGE NON-UNIFORM DUTY RATIO BACKLIGHT DRIVING METHOD

摘要

A side-edge non-uniform duty ratio backlight driving method includes: conducting a simulation operation of driving a side-edge backlight module on the basis of uniform duty ratio according to predetermined liquid crystal panel signal and backlight scanning timing before an actual operation of driving the backlight module is performed; conducting analysis of the number of zones where an interference signal appears when each backlight sections is lit in the simulative operation and distance of the interference signal and ranking the backlight sections according to strength of cross-talking so that a backlight section having less strong cross-talking is set with a higher rank; and carrying out a driving operation according to predetermined scanning timing of the liquid crystal panel signal and the backlighting in actually driving a side-edge backlight module in such a way that a high duty ratio of backlight driving is set to a high-rank backlight section in lighting.
