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

The invention relates to a display screen brightness adjusting method and a device for a display screen. The method comprises the steps that the target brightness of the display screen is determined;when the target brightness is lower than a brightness adjustment threshold value, the display screen is adjusted to first brightness, and the first brightness is larger than the brightness adjustmentthreshold value; and a part of display sub-pixels of the display screen is turned off by adopting a preset adjustment mode, wherein the part of display sub-pixels are symmetrically distributed in thedisplay screen. According to the display screen brightness adjustment method and device provided by the embodiment of the invention, the problem that the display screen is prone to display non-uniform mura under the conditions of low brightness and low gray scale can be prevented, and the problem that electronic equipment is dazzling when used in a dark environment can also be relieved.
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...
