Abstract
A display driving circuit configured to drive a display panel to display a video is provided. The display driving circuit includes a compensating circuit and a gamma voltage generating circuit. The compensating circuit is configured to receive a voltage compensating map of each frame of the video and a pixel line address. The compensating circuit determines a voltage compensating value of each pixel line according to the voltage compensating map of each frame and the pixel line address. The compensating circuit generates a compensated gamma curve of each pixel line. The gamma voltage generating circuit is coupled to the compensating circuit. The gamma voltage generating circuit is configured to generate a gamma voltage of each pixel line according to the compensated gamma curve.
