Manufacturing method of touch screen and touch screen

Abstract

The invention is suitable for the technical field of touch control screens, and provides a method for manufacturing a touch control screen and the touch control screen obtained with the method for manufacturing the touch control screen. The method and the touch control screen achieve the aims that in the prior art, the touch control area of a touch control screen is enlarged, and a frame of the touch control screen is omitted. The method for manufacturing the touch control screen includes the following steps: providing a substrate; arranging conductive materials; etching patterns, forming a touch control pattern circuit in a touch control region, forming a front face lead electrically connected with the touch control pattern circuit in a circuit region, and forming a back face lead on the second surface, wherein the back face lead is electrically connected with the touch control pattern circuit; binding a flexible circuit board; attaching a cover plate. The touch control pattern circuit and the front face lead are formed on the first surface of the substrate, and the back face lead is formed on the second surface of the substrate so that the touch control region where the touch control pattern circuit is formed can be an effective touch control region of the touch control screen, the touch control screen without a frame is accordingly obtained, and the effective touch control area of the touch control screen is greatly enlarged.

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...
