ABSTRACT:
Gray scale distribution of an input image signal is obtained through statistics to determine the contrast characteristic of the input image signal. Based on the gray scale distribution, by a look up table, corresponding gamma setting values are derived and stored in a register. The register outputs the stored gamma setting values to a gray scale voltage generation circuit to adjust the gray scale voltage. Therefore, the display contrast and display quality are improved.
