Problems solved by technology

[0008] 5. Both AMOLED and SUPERAMOLED have a very wide color gamut, but color cast
In the existing driving circuit, there is non-uniformity in the threshold voltage of the driving thin-film transistor of each pixel driving the light-emitting diode, which leads to the fact that even if the same driving voltage is applied to the gate of each driving thin-film transistor, it will flow through each OLED The current may also be different, thus affecting the display effect

Abstract

Disclosed are a pixel compensation circuit and a drive method thereof, an array substrate and a display device. The pixel compensation circuit comprises a reset module (201), a drive module (202), a compensation module (203) and a light-emitting control module (204); the reset module (201) is connected with a reset signal line and the drive module, and is configured to reset the drive module according to a reset signal input by the reset signal line; the drive module (202) is configured to output a drive current to drive light-emitting display of a display device; the compensation module (203) is connected with a signal control line, a data line and the drive module, and is configured to perform threshold voltage compensation and data write-in for the drive module under the control of a signal control signal input by the signal control line; and the light-emitting control module (204) is connected with a light-emitting control line, the drive module and the anode of the display device, and is configured to control the drive module to drive the light-emitting display of the display device according to a light-emitting control signal input by the light-emitting control line. The pixel compensation circuit can effectively prevent an influence of a threshold voltage on a drive current, and the pixel compensation circuit has less signal lines so that the fact that the pixel compensation circuit is used in mask design of a TFT substrate in a high-resolution display screen is facilitated.

Description

technical field [0001] The present disclosure relates to the field of active-matrix organic light-emitting diode displays, and more specifically, to a pixel compensation circuit for active-matrix organic light-emitting diode panel displays and a driving method thereof, an array substrate including the pixel compensation circuit, and a corresponding display device. Background technique [0002] AMOLED (Active-matrixorganiclight-emittingdiode, active-matrix organic light-emitting diode or active-matrix organic light-emitting diode) is a display technology used in TVs and mobile devices. The use of AMOLED technology as a display screen has been loved by customers and has been well received. At the same time, it has also opened up the next display technology AMOLED involving LTPS-LCD (Low Temperature Poly-silicon Liquid Crystal Display). [0003] Compared with traditional display technology, AMOLED has the following advantages: [0004] 1. Compared with the liquid crystal cell...
