Abstract

The invention discloses an array substrate, a manufacturing method of the array substrate and a display panel. The array substrate comprises: a substrate; the pixel driving circuit is arranged on the substrate, the pixel driving circuit comprises a driving transistor and a first transistor, the first transistor is located on a grid leakage path of the driving transistor, and the threshold voltage of the first transistor is larger than that of the driving transistor. The threshold voltage of the first transistor is set to be greater than the threshold voltage of the driving transistor, so that the leakage current of the first transistor in a turn-off state is relatively small, the leakage current on a grid leakage path of the driving transistor where the first transistor is located can be reduced, the grid potential holding time of the driving transistor is prolonged, and the driving efficiency is improved. Therefore, the driving current formed by the driving transistor is relatively stable, the flicker phenomenon of the display panel is reduced, and the display image quality of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of display, and in particular, to an array substrate, a method for manufacturing the array substrate, 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. Contents of the invention [0003] The invention provides a...
