Embodiment Construction

[0079] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0080]At present, self-luminous display devices (such as organic light emitting diode (OLED) display panels) all have the problem of brightness attenuation. Moreover, according to the display content and usage time of the pixels, the brightness attenuation degree of different pixels is different. It generally manifests as: the brightness of the pixel in the constant bright state has a large degree of brightness attenuation. At this time, the pixel with a large brightness attenuation degree will leave an afterimage in the display area, commonly known as "burn-in", which will affect the display performance of the display panel. . For example, a mobile terminal with a folding screen usually has multiple display partitions. During i...

Abstract

The application discloses a brightness compensation method and device for a display panel, a display panel, and a storage medium, and belongs to the field of display technology. The method includes: obtaining the usage parameters of each display partition in the display panel, the display panel has multiple display partitions, the usage parameters are used to reflect the historical usage of the display partitions, and the usage parameters at least include: backlight parameters; Based on the mapping relationship between the use parameters and the brightness attenuation coefficient, respectively obtain the first brightness attenuation coefficient of each display partition, and the first brightness attenuation coefficient of the display partition is used to reflect the brightness attenuation degree of the display partition; based on the display The first brightness attenuation coefficient of the partition is used to perform brightness compensation on the display partition. The present application simplifies the difficulty of obtaining parameters and the complexity of compensation, and improves the accuracy of brightness compensation. This application is used to compensate the brightness of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a brightness compensation method and device for a display panel, a display panel, and a storage medium. Background technique [0002] During the use of the display panel, the display device in the display panel will have aging problems, which will lead to the problem of brightness attenuation of the display panel. Moreover, according to the usage of the display devices at different positions, the aging degrees of the display devices at different positions are different, resulting in different brightness attenuation degrees of the display devices at different positions, which affects the display uniformity of the display panel. Therefore, performing brightness compensation on the display panel is of great significance for improving the display uniformity of the display panel. [0003] In related technologies, the brightness of each pixel in the display panel at different...
