Abstract
The present invention provides a brightness compensation method of a Mura area and a design method of a Mura pixel dot brightness. By searching the right and lower normal pixel dots which are closest to the designated Mura pixel dot, and respectively recording the brightnesses of the right and lower normal pixel dots, and the distances between the right and lower normal pixel dots and the designated pixel dot, with combination of the brightnesses of the left and upper normal pixel dots adjacent to the designated Mura pixel dot, the weighted operation is executed to the brightnesses of the normal pixel dots at the right side, the lower side, the left side and the upper side to obtain the ideal brightness of the designated Mura pixel dot, and replace the original brightness of the designated Mura pixel dot with the obtained ideal brightness. Then, the brightness compensation of the Mura area is accomplished. The brightness of the Mura area after compensation is smoothly transited.
