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 disclosure discloses a liquid crystal display panel and a compensation method thereof. The compensation method firstly acquires a plurality of consecutive and alternating odd-numbered frame grayscale data and even-numbered frame grayscale data, then determines a minimum grayscale difference, and determines a gamma voltage difference corresponding to the grayscale difference according to a curve of a relation between grayscales and gamma voltages, followed by obtaining a correction value for a common voltage based on the gamma voltage difference. The flicker phenomena can be improved by adjusting the common voltage only once with the correction value.
