Abstract

A display driver configured to drive a display panel is provided. The display panel displays an image frame in a first display mode or a second display mode. The display driver includes a first display driving channel and a second display driving channel. The first and the second display driving channels are configured to drive the display panel to display the image frame by using a sub-pixel rendering method. In the second display mode, the second display driving channel drives sub-pixels on the display panel to display corresponding grayscales by using a plurality of gamma voltages. A voltage value of at least one gamma voltage among the gamma voltages is determined according to an arrangement of the sub-pixels on the display panel.
