Abstract

The invention relates to the technical field of display, and especially relates to a pixel circuit, a driving method, and a display device. The pixel circuit can comprise a first switching element, adriving transistor, a storage capacitor, a second switching element, and a light-sensitive element. The pixel circuit is large in compensation range, and ensures uniformity of display brightness of each pixel.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a pixel circuit, a driving method, and a display device. Background technique [0002] In the pixel circuit, due to the instability of the manufacturing process, there are differences in the threshold voltage, mobility, and driving voltage of the electroluminescent element among multiple pixels, resulting in differences in the driving current of the electroluminescent element. , so that the luminous brightness of the electroluminescent elements in each pixel unit is inconsistent, and then the brightness uniformity of the display screen is reduced. [0003] At present, commonly used methods for compensating pixels include internal compensation and external compensation, wherein external compensation includes external electrical compensation and external optical compensation. Internal compensation refers to the method of using sub-circuits built with transistors to ...
