Pixel driving circuit, driving method of pixel driving circuit and display panel

Abstract

The invention discloses a pixel driving circuit, a driving method of the pixel driving circuit and a display panel. The pixel driving circuit comprises: a driving module used for providing driving current for a light-emitting module, wherein the light-emitting module is used for emitting light in response to the driving current; a data writing module which is used for providing data voltage for the driving module; a storage module which is used for maintaining the potential of the driving module; a compensation suppression module which is used for compensating the threshold voltage of the driving module and suppressing the leakage current of the driving module; and an initialization module which is used for initializing the driving module through the compensation suppression module. The compensation suppression module can reduce the leakage current of the control end of the driving module passing through the compensation suppression module, so that the leakage current phenomenon of the control end of the driving module can be improved. Meanwhile, a leakage current path can be prevented from being formed between the driving module and the initialization module, the leakage current phenomenon of the control end of the driving module is further reduced, the stability of the pixel driving circuit is improved, and therefore the display image quality of the display panel is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a pixel driving circuit, a driving method of the pixel driving circuit, and a display panel. Background technique [0002] Active-matrix organic light emitting diode (AMOLED) display panels have been widely used in the display field because they are superior to liquid crystal display panels in terms of display color saturation, power consumption, and bending. During the display process of the AMOLED display panel, the pixel driving circuit drives the light emitting device to emit light. In the prior art, the pixel driving circuit includes a driving transistor, and the gate of the driving transistor has a leakage current phenomenon, and the stability is relatively poor, resulting in unstable luminance of the light emitting device, thereby affecting the display quality of the AMOLED display panel.
