Abstract
An anti-flicker and motion-blur improvement method includes selecting one of display modes, obtaining a vertical synchronization signal and a data clock signal, and setting waveforms of a backlight driving signal in a vertical blanking interval and a data scan interval according to the display mode to make a motion blur effect correspond to the display mode. A voltage regulation signal is generated according to the display mode. A duty cycle of the voltage regulation signal is set as a first duty cycle in a dynamic image display mode. The duty cycle of the voltage regulation signal is set as a second duty cycle in a still image display mode. A backlight driving current corresponding to the backlight driving signal is generated via the voltage regulation signal. A current setting port generates a constant current. Accordingly, the present invention can improve the motion blur phenomenon by simplifying the backlight control circuit.
