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; coating a conductive material; pattern etching, forming a touch pattern line in the touch area and forming a lead wire electrically connected to the touch pattern line at one end in the line area; Fixing the flexible circuit board; attaching the cover plate; attaching the display screen; bending the edge, bending the circuit area along the connection between the touch area and the circuit area, and at least making the first lead wire bend and attach to the surface of the display screen. The first lead wire and the flexible circuit board are bent and attached to the surface of the display screen, so that the touch area formed with the touch graphic circuit is the effective touch area of ​​the touch screen, thereby obtaining a borderless touch screen, The effective touch area of ​​the touch screen is greatly increased.

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...
