Abstract

The application discloses an array substrate, a manufacturing method thereof, and a display panel. In this application, the source pattern and the drain pattern are designed to be directly formed on the dielectric layer, and the traditional flat layer and passivation layer are replaced by the dielectric layer, and the drain pattern is also used as the anode pattern of the OLED device, thereby reducing the The photomask process, and the dielectric layer is made of a light-shielding material, which can protect the channel layer of the TFT from being affected by light, and is beneficial to ensure its stable performance.

Description

technical field [0001] The present application relates to the display field, in particular to an array substrate, a manufacturing method thereof, and a display panel. Background technique [0002] Currently, the TFT (Thin Film Transistor, thin film transistor) whose channel layer is made of metal oxide (Oxide) semiconductor has been widely used in OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panels, in which the top gate Type TFT has become the industry's first choice due to its small parasitic capacitance. However, the preparation of the array substrate (Array substrate) with gate-type TFTs on top requires many mask (Mask) processes, resulting in complicated manufacturing processes, which cannot reduce production costs, and the channel layer is easily affected by light and has unstable performance. Contents of the invention [0003] In view of this, the present application provides an array substrate, a manufacturing method thereof, and a dis...
