AI Technical Summary

Technical Problem

Due to the poor brightness compensation effect caused by image brightness distortion of the display panel, the existing technology uses a multi-camera solution, which increases production costs.

Method used

The display panel is photographed using an image-taking component to obtain brightness data and viewing angle of the area to be corrected. Brightness compensation is performed by correcting the brightness data, and a database of the mapping relationship between display features and viewing angle is established. Brightness correction is performed by using the angle between the optical center of the lens of the image-taking component and the normal of the display panel.

Benefits of technology

It solves the problem of image brightness distortion caused by insufficient camera working distance, improves the accuracy and effect of brightness compensation, and reduces production costs.

Abstract

This application discloses a brightness compensation method and apparatus for a display panel, a readable storage medium, and a display device. The display panel is divided into at least one region, including a region to be corrected. The brightness compensation method includes: taking a picture of the display panel displaying a preset grayscale image using an imaging component to obtain an image of the region to be corrected at the preset grayscale; obtaining brightness data of the region to be corrected from the image of the region to be corrected at the preset grayscale; obtaining the viewing angle of the region to be corrected, wherein the viewing angle is the angle between the line connecting the optical center of the lens of the imaging component and the center of the region and the normal of the display panel; correcting the brightness of the region to be corrected based on the viewing angle to obtain corrected brightness data of the region to be corrected; and performing brightness compensation on the display panel based on the corrected brightness data of the region to be corrected. This application solves the problem that image brightness distortion of the display panel affects the compensation effect.
