Abstract
A backlight driving method is provided to include generating switching signals based on an internal synchronization control (ISC) signal related to refreshing of images on the display, a clock signal, and delay commands contained in a serial input signal that further contains an image stream. A time delay of each switching signal with respect to the ISC signal is determined by the clock signal and a respective delay command, and the time delays of the switching signals are different from one another. The method further includes generating driving signals based on the ISC signal, the clock signal and the serial input signal; and outputting the signals thus generated, to drive the backlight module to emit light in a line scan manner.
