Production method of temperature-resistant pressure-resistant capacitive touch screen panel

Abstract

The invention discloses a production method of a temperature-resistant pressure-resistant capacitive touch screen panel. The production method includes the steps: firstly, cleaning and drying a glass substrate; secondly, forming a removable local shade layer; thirdly, vacuum-plating a black titanium carbide film or black titanium carbonitride film; fourthly, vacuum-plating a silica film on the surface of the titanium carbide film or titanium carbonitride film; fifthly, removing the local shade layer and the portions of the films thereon to obtain the glass substrate with a metal film wire black-film masking frame and a transparent visual area; sixthly, on the back of the glass substrate, forming a transparent ITO (indium tin oxide) conducting film on the transparent visual area, forming a metal film wire connected with the transparent ITO conducting film on the black film masking frame, and forming an OC (over coat) protective layer on the metal film wire; and seventhly, forming the touch screen panel. The temperature-resistant pressure-resistant capacitive touch screen panel is capable of effectively resisting high temperature and high pressure, bonding yield of the touch screen panel and a flexible circuit board is increased, and production cost of OGS (one glass solution) capacitive touch screen modules is reduced greatly.

Description

technical field [0001] The invention relates to a method for manufacturing a capacitive touch screen panel, in particular to a method for manufacturing a temperature-resistant and pressure-resistant capacitive touch screen panel. Background technique [0002] At present, there is a product in the projected capacitive touch screen market that uses a single glass touch panel to replace the touch sensor and cover glass. People are used to calling it "OGS"-- -one glass solution. [0003] The expensive production cost of capacitive touch screen is the main pressure of enterprise competition. The "OGS" capacitive touch screen saves a piece of glass from the structure, which greatly reduces the production cost. At the same time, the touch screen panel can be made lighter and thinner. A piece of glass structure can reduce the reflectivity of projected light, so that the display of the touch screen is clearer. [0004] Any capacitive touch screen must use a metal film wire with a c...

Problems solved by technology

Such binding conditions often cause the organic black photoresist layer or ink layer used to shield the metal film wires to be unable to withstand and rupture, causing the flexible circuit board and the metal film wires of the touch screen to be misaligned, so that the touch screen module is well bound. The efficiency is greatly reduced, and the efficiency and cost of production are also greatly affected.
