Problems solved by technology

[0002] In the pixel driving circuit of Active-matrix (AM) display products, since the storage capacitor is easy to leak through some paths, it is difficult to maintain a stable gate potential of the driving transistor during the light-emitting process, so that the Organic Light-Emitting Diode (Organic Light- Emitting Diode, OLED), quantum dots and other light-emitting elements are difficult to maintain a stable brightness to emit light, resulting in flickering and other phenomena that reduce the display effect

Abstract

The embodiment of the invention provides a pixel driving circuit, a driving method thereof, an array substrate and a display device. The pixel driving circuit comprises a driving module, a storage module, a light-emitting module and a first electric leakage suppression module, and the first electric leakage suppression module is electrically connected with a first node, a second node, a grid signal end and a second power supply end. The processor is configured to switch on the first node and the second node in response to a working level input by the gate signal end in a data writing stage so as to write the data voltage into the first node and store the data voltage, and switch off the electric connection between the first node and the second node in response to a non-working level input by the gate signal end in a light emitting stage; and the leakage current between the first node and the second node is reduced through the stored data voltage. Therefore, the potential of the first node can be better maintained, namely, the driving current can be more stable, so that the flicker phenomenon is improved, and the display effect is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a pixel driving circuit, a driving method thereof, an array substrate and a display device. Background technique [0002] In the pixel driving circuit of Active-matrix (AM) display products, since the storage capacitor is easy to leak through some paths, it is difficult to maintain a stable gate potential of the driving transistor during the light-emitting process, so that the Organic Light-Emitting Diode (Organic Light- Emitting Diode (OLED), quantum dots and other light-emitting elements are difficult to maintain stable brightness to emit light, resulting in flickering and other phenomena that reduce the display effect. Contents of the invention [0003] In view of the shortcomings of the existing methods, the present application proposes a pixel driving circuit, its driving method, an array substrate and a display device, so as...
