Abstract:
A backlight modulation circuit includes an illumination controlling signal generating circuit, an illumination control signal separating circuit, and an illumination modulation circuit. The illumination controlling signal generating circuit is configured for receiving an modulation signal and generating an illumination controlling signal according to the modulation signal. The illumination control signal separating circuit is configured for separating the illumination controlling signal into a first modulation signal and a second modulation signal. The illumination modulation circuit is configured for modulating illumination of a backlight module according to the first and second modulation signals.
