Abstract
A backlight control system and method are disclosed. An overdrive device modifies a backlight duty signal according to a current-frame backlight duty signal and a previous-frame backlight duty signal. In one embodiment, the overdrive device is implemented with a lookup table that outputs the modified backlight duty signal. The backlight driven by the modified backlight duty signal then emits light to a display panel, thereby increasing a response time of the backlight.
