Problems solved by technology

[0004] Due to the complex process and huge equipment investment in the thin film transistor display panel industry, the production cost is very high. With the fierce competition in the market, reducing the production cost of the screen is the inevitable development direction of the flat panel display industry, and most of the old thin film transistor display The panel production line is only suitable for the production process of red, green and blue primary color technology, and there is no production equipment and workshop space related to transparent photoresist

Embodiment Construction

[0055] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] Such as figure 1 and figure 2 As shown, an embodiment of the present invention provides a method for manufacturing an active switch array substrate, including the following steps:

[0057]Step S100, forming a first metal layer on a substrate 100, and etching the first metal layer to form the gate 1 of the active switch;

[0058] Step S200, depositing an insulating layer 2 on the substrate 100 and the gate 1;

[0059] Step S300, depositing an active layer 3 and an ohmic contact layer 4 on the insulating layer 2;

[0060] Step S400, depositing a second me...

Abstract

The invention is suitable for the technical field of display screens, and provides an active switch array substrate and a manufacturing method thereof and a display panel. The coating, exposure and development process of transparent photoresistance is not required in the manufacturing process of the substrate, and film forming operation of a second insulating layer is not required; and a photoresist layer is not required to be removed subsequently and the photoresist layer is reserved on the panel and the subsequent pixel electrode manufacturing process is continued. Therefore, the equipment investment cost for producing the transparent photoresistance and the subsequent mask plate cost can be saved by producing the substrate and the display panel having the substrate, and a white, red, green and blue four-color technical panel can be produced under the condition of slightly changing the red, green and blue three-color production line; meanwhile, the production time can be shortened, the production cost can be reduced and the efficiency and the productivity of the production line can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of display screens, and in particular relates to an active switch array substrate, a manufacturing method thereof, and a display panel. Background technique [0002] More and more display panel manufacturers use the process of making color filter film (Color Filter on Array, COA) on the array of thin-film transistor (Thin-film transistor, referred to as TFT) and white, red, green and blue four colors (white, red, green, blue, referred to as WRGB) technology. Among them, the COA process can improve the image quality of the curved surface of the display panel or simplify the structure of the upper plate (for example: simplify the planarization layer (Over Coat, OC) structure of the upper plate of the liquid crystal mode (In-Plane Switching, referred to as IPS) ); and WRGB technology can improve panel penetration, reduce panel energy consumption and save backlight costs. [0003] The array process (Array) pro...
