Abstract

Embodiments of the present application provide a pixel driving circuit, a display panel, a display device, and a pixel driving method. The pixel drive circuit includes: a first switch module, the first end, the second end, and the control end are respectively electrically connected to the data signal line, the first node, and the first gate signal line; the charge storage module, the first end, the second The two terminals are respectively electrically connected to the first node and the second node; the drive module, the first terminal, the second terminal, and the control terminal are respectively electrically connected to the first level terminal, the second node, and the first node; the second switch module is electrically connected to the second node. The first terminal, the second terminal, the third terminal and the control terminal are respectively electrically connected to the initialization signal line, the third node, the second node, and the second gate signal line, and the third node serves as the third terminal of the charge storage module. The embodiment of the present application realizes the compensation of the light-emitting device OLED, and reduces or eliminates the problem of uneven luminescence caused by the aging effect of the light-emitting device OLED.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a pixel driving circuit, a display panel, a display device, and a pixel driving method. Background technique [0002] In the design of AMOLED (Active-matrix organic light emitting diode, active-matrix organic light-emitting diode) large-size display, the uneven brightness of the product not only depends on the driving TFT (Thin Film Transistor, Thin Film Field-Effect Transistor), but also the light-emitting device OLED (Organic Light-Emitting Diode (organic light-emitting diode) also affects the final display effect. [0003] At present, the driving TFT is generally compensated by an electrical compensation method, through which the influence of the threshold voltage Vth and the mobility of the driving TFT on the display effect can be effectively reduced. However, the light-emitting device OLED will have aging phenomenon after long...
