Abstract

The disclosure provides a pixel driving circuit, a driving method, and a display device, which are applied to the field of display technology. The pixel driving circuit includes a first switching element, a second switching element, a third switching element, a fourth switching element, a fifth switching element, a sixth switching element, a driving transistor, and a storage capacitor. According to the disclosure, the short-term afterimage problem caused by a hysteresis effect is improved, the display quality is improved, the influence of a threshold voltage of the driving transistor on a driving current is also eliminated and therefore, the uniformity of display luminance of each pixel is ensured.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a pixel driving circuit, a pixel driving method, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED), as a current-mode light-emitting device, is increasingly being used because of its characteristics such as self-luminescence, fast response, wide viewing angle and the ability to be fabricated on flexible substrates. In the field of high-performance display. An OLED display is a display made of organic light-emitting diodes. Due to its self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response, flexible panels, wide operating temperature range, simple structure and manufacturing process, etc., it is considered to be the next A generation of emerging application technologies for flat panel displays. [0003] At present, due to the hysteresis effect of the drive transistor in the p...
