Abstract

According to a pixel driving circuit and a display panel provided by the invention, the pixel driving circuit of a 5T1C structure is adopted to effectively compensate the threshold voltage of a driving transistor in each pixel, so that the electric leakage power consumption of the pixel driving circuit during threshold voltage extraction can be effectively reduced, and the compensation precision of the pixel driving circuit is further improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a pixel driving circuit and a display panel. Background technique [0002] As a new generation display technology, AMOLED (Active Matrix Organic Light Emitting Display) has higher contrast ratio, faster response speed and wider viewing angle, and has been widely used in the field of high-performance display. In terms of driving mode, AMOLED is a current-driven type, which is sensitive to the electrical variation of the transistor. The uniformity and drift of the threshold voltage Vth of the transistor affect the accuracy and uniformity of the screen display. In order to solve this problem, it is usually introduced Pixel compensation circuit. [0003] Printed display technology is one of the important directions for the development of AMOLED display. However, the start-up voltage of printed OLED devices is relatively low, and traditional pixel compensation circuits are...
