Abstract

The invention provides a display base plate and a control method thereof, and a display device. The display base plate comprises a substrate base plate, a photosensitive circuit formed on the substrate base plate and a plurality of pixel units. Each pixel unit comprises a plurality of sub-pixels. The photosensitive circuit comprises a photosensitive component used for detecting sub-pixel luminance, and an orthographic projection area of the photosensitive component on the substrate base plate is not superposed with the orthographic projection area of the sub-pixels on the substrate base plate.By using the display substrate and the control method thereof, and the display device, a display effect of the display device can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a control method thereof, and a display device. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, display devices have become inaccessible devices in people's daily life. In the related art, due to the instability of the manufacturing process of the display substrate, there are differences in the threshold voltage, mobility, and driving voltage of the electroluminescent element of the driving transistor among multiple pixels, thereby causing the driving current of the electroluminescent element The difference makes the electroluminescence elements in each pixel unit have inconsistent luminance, that is, the Mura phenomenon, which reduces the display effect of the display device. Contents of the invention [0003] Embodiments of the present invention provide a d...
