Abstract: A brightness correcting method of a display panel and a brightness correcting device are disclosed. The method divides a displayed image of the display panel into a first area and a plurality of second areas disposed surrounding the first area. A brightness correction factor of each of the second areas is obtained according to a brightness of the first area and a brightness of each of the second areas. An optical compensation value is adjusted according to the brightness correction factor. The method corrects a brightness of the display panel to allow uniformity of overall brightness of the display panel to meet requirements.

Abstract: The present invention discloses a display panel grayscale compensation method, a grayscale compensation device, and a grayscale compensation system. The grayscale compensation method, by acquiring at least one set of image data corresponding to bonding point grayscale values of the display panel, and by dividing the display panel into a main display region and sub-display regions through the image data, can determine grayscale compensation values corresponding to pixels in the sub-display region according to the average gamma value of each sub-display region, which can increase precision of a single grayscale compensation of the pixels in the display panel.
