Manufacturing method of touch screen and touch screen

Abstract

The present invention is applicable to the technical field of touch screens, provides a method for manufacturing a touch screen and a touch screen obtained by the method, and aims to solve how to increase the touch area of ​​a touch screen and realize touch control in the prior art. The technical problem of borderless control screen. The manufacturing method of the touch screen includes the following steps: providing a substrate; setting a conductive material; pattern etching; binding a flexible circuit board; attaching a cover plate; attaching a display screen; The wiring area is bent at the connection, so that the front leads and the flexible circuit board are bent and adhered to the surface of the display screen. By forming the touch pattern lines and front leads on the first surface of the substrate and forming the back leads on the second surface, bending the front leads and the flexible circuit board and attaching them to the surface of the display screen, so that the touch pattern lines are formed The touch area of ​​the touch screen is the effective touch area of ​​the touch screen, thereby obtaining a touch screen with no borders all around, which greatly increases the effective touch area of ​​the touch screen.

Description

technical field [0001] The invention belongs to the technical field of touch screens, and in particular relates to a manufacturing method of a touch screen and a touch screen obtained by the method. Background technique [0002] At present, capacitive touch screens basically occupy the entire mobile phone touch screen market, and larger screen ratios, ultra-narrow bezels or no bezels can provide a good touch experience, and are increasingly sought after by people. Especially for smart wearable devices, due to their small touch area, how to effectively use the small touch area has become one of the urgent problems to be solved, so ultra-narrow bezel or even bezel-less touch has emerged as the times require. [0003] In the structure of the existing touch screen, the wiring of the conductive film layer in the window area runs from the left and right edges of the touch screen, and then concentrates on the binding area to connect with the flexible circuit board. Since the left a...
