Abstract

The invention provides a touch screen preparation method, which comprises the following steps of providing a conducting film of which the surface is provided with a patterned touch electrode; coating photoresist on the side, provided with the touch electrode, of the conducting film for forming a photoresist layer; exposing the photoresist layer through photomask with a preset pattern under illumination to obtain the exposed photoresist layer; developing the exposed photoresist layer, and obtaining a groove which is positioned at the edge of the touch electrode and is connected with the touch electrode from the photoresist layer; filling and solidifying conducting materials in the groove, and forming the conducting materials into the groove into a lead wire; removing the photoresist layer for exposing the lead wire. According to the touch screen preparation method, the photoresist layer is exposed and developed for generating the groove, and the conducting materials are filled into the groove for forming the lead wire, compared with a manner of directly printing a lead wire, the lead wire obtained by utilizing an exposure and development technology is finer in circuit, and the design requirements of narrow bezel touch screens are met.

Description

technical field [0001] The invention relates to touch screen technology, in particular to a touch screen preparation method. Background technique [0002] A touch screen is an inductive device that can receive input signals such as touch. The touch screen has endowed information interaction with a new look and is an attractive new information interaction device. It is widely used as an input terminal in electronic products such as mobile phones, TV sets, and tablet computers. With the increasing demand for the appearance and aesthetics of electronic products (minimizing the frame and maximizing the window), the narrow frame touch screen is slowly becoming a fashion design trend. [0003] The frame of the touch screen has multiple leads connected to the conductive patterns in the visible area of ​​the touch screen. In order to realize the narrowing of the frame of the touch screen, the lead wires need to minimize the line width and distance. Generally, the lead wires of a t...
