Abstract

The invention provides a pixel driving circuit, a driving method thereof and a display device. The circuit comprises a first switch circuit, a second switch circuit, a third switch circuit, a pull-down switch circuit, a driving switch circuit, a first capacitor and a second capacitor, the first capacitor and the second capacitor are coupled. Voltage of the control end of the driving switch circuitis pulled up twice on the basis of a high-level signal. The control end of the driving switch circuit obtains sufficient driving voltage; and the first end and the second end of the driving switch circuit are controlled to be conducted, so that the signal output end outputs a high-level signal, the problem of abnormal picture display caused by insufficient driving voltage of the driving switch circuit can be avoided, the area of the TFT panel does not need to be increased, and the driving circuit is suitable for a narrow-bezel display screen.

Description

technical field [0001] The present invention relates to the technical field of display screens, in particular to a pixel driving circuit, a driving method thereof, and a display device. Background technique [0002] With the development of the flat panel display technology, a new technology of directly manufacturing the gate driver of the flat panel display device on the glass substrate through mask plate coating technology——GIP (Gate in Panel, door panel) technology has emerged. This technology integrates the scanning chip on the display panel, so as to save the scanning chip, reduce the material cost, reduce the process steps and shorten the process time, thereby reducing the panel cost and realizing the purpose of narrower frame. [0003] At present, the GIP pixel circuit generates scanning signals by receiving DC and clock signals. The DC and clock signals generally only have high-level signals and low-level signals. If N-type TFT (Thin-Film-Transistor, Membrane switch ...
