Abstract

An integrated circuit for driving a display panel is provided. The integrated circuit includes a gamma mapping circuit and a mura compensation circuit. The gamma mapping circuit is configured to receive a gray level of an image data, map the gray level to a gamma code according to at least one gamma table, and output the gamma code. The mura compensation circuit is configured to receive the gamma code, and compensate the gamma code according to at least one de-mura table to generate a compensation result after the gamma mapping circuit performs the step of mapping the gray level to the gamma code. The integrated circuit drives the display panel according to the compensation result. In addition, a method for driving a display panel is also provided.
