Abstract

The embodiment of the invention discloses a display panel brightness correction method and device. The method comprises: dividing a display image of a display panel into a first area and a plurality of second areas arranged on the periphery of the first area; obtaining a brightness correction coefficient of each second area according to the brightness of the first area and the brightness of each second area; and adjusting an optical compensation value according to each brightness correction coefficient. Therefore, the brightness of the display panel is corrected, so that the uniformity of the overall brightness of the display panel meets the requirement.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method and device for correcting brightness of a display panel. Background technique [0002] At present, in the modern communication industry, the market demand for mobile phones, TVs, tablets, notebooks, digital cameras and other products is increasing, and various display devices are also developing towards high resolution. Therefore, the uniformity of the overall brightness of the display panel also faces some new requirements. [0003] Among them, due to differences in transient voltage and gamma voltage at the center and corner of the liquid crystal display panel, the uniformity of the overall brightness of the display panel is not up to standard, and cannot meet the requirements for the uniformity of the overall brightness of the display panel. The areas where the uniformity of the overall brightness of the display panel does not meet the standard are general...
