Pixel circuit, driving method of pixel circuit, and display device

Abstract

The invention provides a pixel circuit, a driving method of the pixel circuit, and a display device. The pixel circuit comprises a resetting module, a writing-in module, a driving module, a control module, a light emitting module and a compensating module, wherein the resetting module is connected to a first node, a second node and the driving module; the writing-in module is connected to the first node, the second node, the driving module and the control module; the driving module is connected to the first node, the second node, the resetting module, the writing-in module and the control module; the control module is connected to a third node, the first node, the writing-in module, the driving module and the light emitting module; the light emitting module is connected to the control module; and the compensating module is connected to the third node. According the pixel circuit, the driving method of the pixel circuit, and the display device provided by the invention, a splash-screen phenomenon appearing in the first frame of display picture after a product is started up can be prevented, so that abnormal display of the first frame of display picture is prevented, and subsequently, the display effect of the product is enhanced.

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...
