Problems solved by technology

[0003] However, as the service life of the display panel increases, there will be a difference in brightness between the secondary screen of the display panel and the main screen of the display panel (that is, the display area of ​​the display panel other than the secondary screen), resulting in a poor display effect of the display panel.

Abstract

The embodiment of the invention provides a compensation method and device of a display panel and a computer readable storage medium. The display panel comprises a first display area and a second display area. The method comprises the following steps: acquiring a plurality of first brightness compensation values of different gray scales, a plurality of second brightness compensation values of different temperatures and a plurality of third brightness compensation values of different brightness levels under different use durations in advance; determining a first brightness compensation value of the current gray scale, a second brightness compensation value of the current temperature and a third brightness compensation value of the current brightness level under the current use duration when the current use duration is greater than or equal to the first duration threshold value; according to the determined first brightness compensation value, the second brightness compensation value and the third brightness compensation value, determining a data voltage compensation amount or a duty ratio of a light-emitting control signal; and performing brightness compensation on the first display area based on the data voltage compensation amount or the duty ratio of the light-emitting control signal. According to the embodiment of the invention, the brightness attenuation difference between the first display area and the second display area can be eliminated.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a compensation method, device and computer-readable storage medium for a display panel. Background technique [0002] With the rapid development of display panels, users have higher and higher requirements for screen-to-body ratio, so that the full-screen display of display panels has attracted more and more attention from the industry. At present, the design of Under Display Camera or Camera Under Panel (UDC or CUP) appears. The under-display camera means that the front camera is located under the display panel and does not affect the display function of the display panel. For example, when the user does not use the front camera, the display area above the front camera (referred to as UDC area or CUP area, also known as the secondary screen) can display images normally; when the user uses the front camera, the display area above the front camera Regions m...
