Problems solved by technology

[0005] The object of the present invention is to provide a method for manufacturing driving wires, a display panel and a method for manufacturing a display panel, so as to solve the problem of complex process for preparing array substrates, high production cost and the existence of wires made by etching in the prior art. Undercut phenomenon, the data lines or gate lines on the array substrate often have short circuit or open circuit, which leads to the inability to solve the technical problems of high resistance of the conductive layer and large parasitic capacitance of the conductive layer

Abstract

The invention provides a manufacturing method of a driving wire, a display panel and a manufacturing method of the display panel. The manufacturing method of the driving wire comprises the following steps: covering a metal film on an array substrate, and pressing the metal film on the array substrate; and performing yellow photoetching on the metal film to form a patterned driving wire. According to the invention, the array substrate and the metal film are laminated together, and the metal film is subjected to the subsequent yellow photoetching process to obtain the desired patterned driving wire, so the undercutting phenomenon of the wire manufactured by the existing etching mode is overcome, and the defects of short circuit or open circuit and the like are avoided; in addition, due to the fact that the thick copper technology is achieved on the array substrate through the manufacturing method, the small-resistance design of driving wiring is achieved, the manufacturing process is simplified, stray capacitance can be reduced, and the product specification can be improved.

Description

technical field [0001] The present invention relates to the field of display, in particular to a manufacturing method of driving wiring, a display panel and a manufacturing method of the display panel. Background technique [0002] With the advancement of technology and the development of the times, people have higher and higher requirements for mobile phone display screens. The current mainstream hard screen display can no longer meet the needs of the market. [0003] In the prior art, array substrates include conductive layer structures such as data lines or gate lines, which are mostly produced by evaporation or sputtering. Layer parasitic capacitance is large. In order to solve this problem, if the method of directly increasing the thickness of the prepared data line or gate line is adopted, undercutting is easy to occur when etching the metal layer to form a patterned data line or gate line, and the manufacturing process is difficult; The insulating layer in the midd...
