Abstract

The present invention provides an array substrate, a display device and a driving method thereof, relates to the technical field of display, and can improve the problem that the compensation signal isnot accurate due to the inaccuracy of the signal received on the detection IC due to the weak compensation signal in the prior art. The array substrate comprises a plurality of sub-pixels; each of the sub-pixels is correspondingly provided with a photo-sensing detecting component, the photo-sensing detecting component comprises a photosensitive element and a signal reading element, the photosensitive component is connected to a first voltage end and a second voltage end and used for detecting the luminance of the sub-pixel and transmitting an electrical signal corresponding to the luminance of the sub-pixel to an output end of the photosensitive element, the signal reading element is also is connected to the output end and a signal reading line, and used for reading an electrical signal output by the output end and transmitting the electrical signal to the signal reading line; and wherein the sub-pixels at least partially correspond to the photosensitive elements in the photo-sensingdetecting components arranged correspondingly to the sub-pixels.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display device and a driving method thereof. Background technique [0002] Organic Light Emitting Diode (OLED) display is one of the hotspots in the current research field. Compared with Liquid Crystal Display (LCD), OLED has low energy consumption, self-illumination, wide viewing angle and fast response speed. Etc. [0003] However, due to the process, materials and design of OLED display devices, it is easy to cause the threshold voltage of the driving thin film transistor to drift and the mobility (electron mobility) to fluctuate, resulting in different driving currents and uneven brightness of the display screen. . [0004] Based on this, in the prior art, an electrical compensation method is usually used to compensate for threshold voltage drift and mobility fluctuation, so as to ensure the uniformity of the driving current. Compensation cir...
