Abstract

The invention provides a pixel circuit, a driving method thereof, and a display device. The pixel circuit includes a reset module, a write module, a drive module, a control module, a light emitting module and a compensation module; the reset module is connected to the first node, the second node and the drive module, and the write module is connected to the first node, the The second node, the drive module is connected to the control module, the drive module is connected to the first node, the second node, the reset module, the write module and the control module, the control module is connected to the third node, the first node, the write module, and the drive module It is connected with the light emitting module, the light emitting module is connected with the control module, and the compensation module is connected with the third node. The pixel circuit, its driving method, and the display device provided by the present invention avoid the flickering phenomenon of the first frame of the display screen after the product is turned on, so that the first frame of the display screen does not appear abnormal display, thereby improving the product quality. display effect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel circuit, a driving method thereof, and a display device. Background technique [0002] Due to the influence of the pixel compensation circuit of traditional organic light-emitting diode (Organic Light-Emitting Diode, referred to as: OLED) products, abnormal charging of the product often occurs in the first frame time after startup. [0003] In the pixel circuit in the prior art, when the product is powered on and started, the driving voltage jumps. For example, the driving voltage jumps from 0V to 4.6V. The first frame of the display screen has a flickering phenomenon, which makes the first frame of the display screen display abnormally, thus affecting the display effect of the product. Contents of the invention [0004] The present invention provides a pixel circuit, a driving method thereof, and a display device, which are used to avoid the flickering phenom...
