Abstract

The invention discloses a display substrate, its brightness adjustment method, and a display device; the display substrate includes: a base substrate, and a plurality of pixel units arranged on the base substrate; the display substrate further includes: a first A detection unit, there are multiple first detection units and they are all arranged in the effective display area of ​​the display substrate; each of the first detection units is arranged corresponding to at least one of the plurality of pixel units, for detecting the ambient light intensity of the corresponding pixel unit; a processing unit for generating a first control signal according to the ambient light intensity respectively corresponding to the plurality of pixel units, and adjusting the Display brightness of the plurality of pixel units. The invention performs environment-based brightness adjustment for each pixel unit, solves the problem of uneven brightness of a display device, and improves display effect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a brightness adjustment method thereof, and a display device. Background technique [0002] Currently, various types of display devices have been widely used in various fields. Among them, the display brightness has an important influence on the display effect of the display device, so some existing display devices have a brightness adjustment function. However, the existing display devices that can automatically adjust the brightness generally use light sensors to detect ambient light. The number of sensors on the display device is limited, and most of them are located around the display device. They can only detect the ambient light around the sensor, and cannot display finely. Each area of ​​the device, which causes the problem of uneven brightness in the central area and surrounding areas of the display device, which affects the display effect. ...
