Description

Technical field [0001] The present application belongs to the technical field of display, and more particularly to a pixel driving circuit, a driving method, a display panel, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) is increasingly widely used in display areas due to its advantages of active illuminating, visual angle, fast, color gamut and low power consumption. [0003] However, the inventors of this application have found that the OLED display panel will show the color polarization phenomenon that is biaed or biased when the low brightness is displayed, and there is a problem that the display effect is poor. Inventive content [0004] The present application embodiment provides a pixel driving circuit, a driving method, a display panel, and a display device, which can be applied to the OLED display, which can solve the color shift problem of the OLED display panel and improve the display effect. [0005] In the first aspect, the ...
