Problems solved by technology

However, limited by the material and process, the OLED display is prone to display uneven mura in the case of low brightness and low gray scale.
[0003] If the minimum brightness of the OLED display is increased to avoid the problem of uneven display mura, it will cause glare when the electronic device is used in a dark environment

Abstract

The present disclosure relates to a method and device for adjusting brightness of a display screen, including: determining the target brightness of the display screen; when the target brightness is lower than a brightness adjustment threshold, adjusting the display screen to a first brightness, the second a brightness greater than the brightness adjustment threshold; a preset adjustment method is used to turn off part of the display sub-pixels of the display screen, and the part of display sub-pixels are symmetrically distributed in the display screen. The method and device for adjusting the brightness of a display screen according to the embodiments of the present disclosure can avoid the problem that the display screen is prone to uneven display mura in the case of low brightness and low grayscale, and can also alleviate the problem of electronic equipment being used in a dark environment. glaring question.

Description

technical field [0001] The present disclosure relates to the field of terminal technologies, and in particular to a method and device for adjusting brightness of a display screen. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display screen has the advantages of wide color gamut, low power consumption, light and thin, and is widely used in electronic equipment. However, limited by materials and processes, OLED displays are prone to the problem of uneven display mura in the case of low brightness and low grayscale. [0003] If the minimum brightness of the OLED display is increased to avoid the problem of uneven display mura, it will cause glare when the electronic device is used in a dark environment. Contents of the invention [0004] In order to overcome the problems existing in the related technologies, the present disclosure provides a method and device for adjusting the brightness of a display screen. [0005] Accord...
