[0024] In order to reduce the correction time of the display device, the inventor of the present invention discloses a brightness correction method in Taiwan Patent Application No. 098125483, which uses a conversion function to perform coordinate conversion, and converts the original pixel brightness and gray scale The exponential relationship, after coordinate conversion, is transformed into a linear relationship in the new coordinates. In this way, the linear interpolation method can be used to deduce the relationship between brightness and gray level in each sampling pixel that has not been actually measured, and become a linear correction function exclusive to each sampling pixel. Then, by comparing the linear correction function of the sampled pixel with the linear correction function of the reference pixel, the relationship between each grayscale value of each sampled pixel and the adjusted new grayscale value can be judged, that is, the brightness correction value δE, an...
