Abstract
The present invention provides a method of selecting a gamma reference voltage. The method is used to switch the picture to a first grey scale. The second grey scale and its luminance of a plurality of regions of a liquid crystal display panel are determined by a sensor, and the gamma voltage corresponding to the second grey scale is stored into a bank to output. The bank signal is input to a reference voltage.
