The array substrate of the present invention is applied to a display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate and a manufacturing method thereof, a driving transistor, and a display panel. Background technique [0002] An organic light-emitting diode (English: Organic Light-Emitting Diode; abbreviation: OLED) display panel includes an array substrate. The array substrate includes: a base substrate, on which a plurality of pixel regions arranged in an array are arranged, and each pixel region is provided with an OLED and a pixel circuit, and the pixel circuit is used to control the OLED to emit light. [0003] In one pixel area, the pixel circuit may include a switching transistor and a driving transistor, both of which are polysilicon transistors. The source and gate of the switching transistor are connected to the control integrated circuit (English: Integrated Circuit; IC for short), the drain of the switching transistor is connected to the gate of the dr...
