Abstract

The invention provides a pixel driving circuit, a pixel driving method, a display panel and a display device. The pixel driving circuit comprises a first pixel driving unit and a second pixel driving unit, wherein the first pixel driving unit comprises a first driving transistor, a first storage unit and a first driving control unit, the first driving control unit controls the jumping compensation on threshold voltage of the first driving transistor through exerting jumping voltage on data voltage in the first compensation stage, the second pixel driving unit comprises a second driving transistor, a second storage unit and a second driving control unit, and the second driving control unit controls the jumping compensation on threshold voltage of the second driving transistor through exerting the jumping voltage on the data voltage in the second compensation stage, and controls the luminescence of a second luminous element. The aperture opening ratio and the cost of a pixel unit can be greatly reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel driving circuit, a method, a display panel and a display device. Background technique [0002] AMOLED (Active Matrix / Organic Light Emitting Diode, Active Matrix Organic Light Emitting Diode) display is one of the hot spots in the field of flat panel display research. Organic light-emitting diodes (OLEDs) have the advantages of low energy consumption, low production cost, self-illumination, wide viewing angle and fast response speed. Pixel drive circuit design is the core technical content of AMOLED display, which has important research significance. [0003] In AMOLED displays, a stable current is required to control OLED light emission. Due to the process and device aging, the threshold voltage (Vth) of the driving transistor of each pixel in the AMOLED display will drift, which causes the current flowing through each pixel OLED to change due to the change of ...
