Embodiment Construction

[0024] It can be seen from the background art that the compensation effect of the current brightness compensation method still needs to be improved.

[0025] The brightness compensation method currently used is: collect brightness data under preset brightness through Demura equipment. The preset brightness can be normal brightness or standard brightness set by the manufacturer or user, and then generate brightness compensation data based on the collected brightness data. According to the The brightness compensation data compensates the display panel to achieve the purpose of eliminating mura. The analysis found that the brightness compensation data of this brightness compensation method is only determined in the preset brightness mode, so the compensation result for the display screen at the preset brightness is the most accurate; and after the user lowers the brightness during use, There will be a problem that the compensation effect is weakened or even invalidated, and the u...

Abstract

The invention provides a screen body brightness compensation system and method and electronic equipment, and the system comprises a first obtaining module which is used for obtaining first brightnesscompensation data, and the first brightness compensation data is the brightness compensation data of a screen body under the preset brightness; the system also comprises a failure brightness acquisition module, the failure brightness acquisition module is used for calling the first brightness compensation data to perform first brightness compensation on the screen body with the brightness lower than the preset brightness to acquire failure brightness, and the failure brightness is the brightness of the screen body corresponding to the condition that the compensation effect of the first brightness compensation is lower than the expected effect; the system further comprises a second acquisition module, the second acquisition module is used for acquiring second brightness compensation data ofthe screen body under the failure brightness; and the system also comprises a compensation module, the compensation module is used for calling the first brightness compensation data or the second brightness compensation data based on the current brightness of the screen body to perform real-time brightness compensation on the screen body. According to the invention, the compensation effect of thescreen body under different brightness can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a screen brightness compensation system and method, and electronic equipment. Background technique [0002] Currently, the display panel has a Mura phenomenon. Mura refers to the non-uniform display of the display panel. The reasons include: affected by the process level, the purity of raw materials, etc., it is difficult to maintain the same electrical parameters such as the threshold voltage or electron mobility of transistors in different regions. [0003] In order to compensate for the mura phenomenon caused by defects in the manufacturing process, brightness compensation is generally used to correct the display brightness in the display panel, thereby eliminating the mura phenomenon. [0004] However, the effect of the current brightness compensation method on correcting the display brightness in the display panel still needs to be improved. Con...
