Abstract

The invention discloses a display panel compensation method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a panel target brightness value according to a preset amplification proportion and panel set brightness when a screen fingerprint recognition mode or an HDR mode is entered; calculating a panel target current value according to the gray-scale value of the input image, the panel resolution and the RGB average pixel ratio; calculating a compensation reference value according to the panel target current value and the panel target brightness value; constructing a relation model between the input image gray-scale value and the output image gray-scale value according to the compensation reference value; and calculating a compensation gray-scale value of an output image according to the gray-scale value of the input image and the relation model. According to the technical scheme, when the panel enters the screen fingerprint recognition mode or the HDR mode, the brightness of the display panel can be adjusted and can break through the maximum limit, and the brightness and color of a display picture are uniform and consistent and cannot be changed along with the magnitude of current.

Description

technical field [0001] The present application relates to the field of display control, in particular to a compensation method, device, electronic equipment and storage medium for a display panel. Background technique [0002] With the development of semiconductor technology, the phenomenon of voltage drop or rise often occurs in the integrated circuit of the display device, and this phenomenon is usually called power supply voltage drop (IR-Drop). Due to the existence of IR-Drop, the magnitude of the current in different regions of the display panel is different, resulting in uneven brightness and color of the displayed image. [0003] In the prior art, the traditional IR-Drop Compensation method (IRC) can make the brightness and color of the display panel consistent no matter how much current the panel is in. However, when the screen fingerprint recognition function or HDR (High-Dynamic Range, high dynamic range image) needs to be applied, and the display panel needs to p...
