Abstract

The invention provides a brightness compensation method, device and system of a display panel, the display panel and a medium. The brightness compensation method comprises the following steps: acquiring a display image of a display panel; determining at least one to-be-compensated area in the display panel according to the display image; wherein each to-be-compensated area comprises a plurality ofpixels; and for each to-be-compensated region, determining a region brightness compensation value of the to-be-compensated region, and performing brightness compensation on each pixel in the to-be-compensated region according to the region brightness compensation value. Regional compensation of the display panel is achieved, and the display panel is suitable for some situations where the center area cannot be adopted for overall compensation.

Description

technical field [0001] The present application relates to the field of display technology, in particular, the present application relates to a brightness compensation method, device, system, display panel and medium of a display panel. Background technique [0002] The current Demura algorithm for brightness compensation of the display panel uses the brightness of the entire screen for comprehensive consideration, selects the central area as the target brightness, and calculates the compensation parameters based on the brightness of other surrounding areas. [0003] However, the above compensation method is not suitable for specific areas formed by the special shape of the display panel, such as AA hole (display hole indicating the AA area is the effective display area), notch (groove), camera area in the display screen of the camera under the screen, etc. For the mura area of ​​special-shaped screens, if the above compensation method is used to compensate for a specific are...
