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.
