Abstract
A control apparatus for driving a display panel and a method thereof are provided. The control apparatus includes an image flickering detector and a chopper selector. The image flickering detector detects whether a present image pattern displayed on the display panel is flickering or not. The chopper selector selects a first chopper mode from a plurality of chopper modes for adjusting gamma voltages of a display image data, and detects whether the present image displayed on the display panel according to the display image data is flickering or not by the image flickering detector. The chopper selector selects a second chopper mode to adjust the gamma voltages of the display image data in response to the present image being flickering. The first chopper mode is different from the second chopper mode.
