Abstract
The present disclosure provides a gamma correction system and method. In the present disclosure, a gamma correction method used for a display panel of a liquid crystal display includes: measuring actual brightness values of preset highest grayscale and lowest grayscale of a central region of the display panel; calculating target brightness values of respective preset tie-point grayscales of the central area based on the actual brightness values, wherein the respective preset tie-point grayscale are located between the preset highest grayscale and the lowest grayscale; adjusting the respective preset tie-point grayscale of the central region and regions of both sides respectively according to the target brightness values, and computing compensating grayscale values of the adjusted respective preset tie-point grayscale; storing the compensating grayscale values, and correcting the gamma curves of the central region and the regions of both sides by using the stored compensating grayscale values.
