Abstract

The invention provides a method for manufacturing a touch screen and the touch screen, relates to the field of display, and aims to solve the technical problem that a process for manufacturing the touch screen is complicated in the prior art. The method for manufacturing the touch screen comprises the following steps of: depositing metal on a substrate, and forming a metal layer pattern by a first composition process, wherein the metal layer pattern comprises a bridging line of a display area; performing inkjet printing on the substrate with the metal layer pattern by using a first protection material to deposit the first protection material on the bridging line so as to form a first protection layer pattern; depositing a transparent conducting material on the substrate with the first protection layer pattern, and forming a transparent conducting layer pattern by a second composition process; and depositing an insulating material on the substrate with the transparent conducting layer pattern, and forming a second protection layer pattern by a third composition process. By the method, the process of manufacturing the touch screen can be simplified.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a manufacturing method of a touch screen and the touch screen. Background technique [0002] There are two types of touch screens: resistive and capacitive. Since the capacitive touch screen has high sensitivity, long life, and supports multi-touch, it has become the mainstream touch technology nowadays. The capacitive touch screen is divided into self-inductance touch screen and mutual inductance touch screen. The following introduces several methods of making interactive touch screens: [0003] 1. Double-layer indium tin oxide ITO (or other transparent conductive layer patterns) touch screen: 5Mask (reticle) mode [0004] The horizontal ITO layer and the vertical ITO are deposited twice and masked twice respectively. The horizontal ITO and the vertical ITO are separated by insulating layers such as SiNx (silicon nitride) or OC (organic insulating layer), and finally a pr...
