Embodiment Construction

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] A manufacturing method of black insulating film frame for OGS touch screen. Stripping technology is used to realize the patterning of black insulating film to form a process scheme of black insulating film frame. The black insulating film can be selected from a variety of materials, preferably black nickel oxide ( The NiO film is a black insulating film, and the specific process includes: cleaning→gluing→exposure→development, hardening→sputtering NiO black insulating film→removal and peeling→inspection; the specific steps are as follows:

[0030] It includes the following steps:

[0031] (1) Cleaning, insert the cover glass into the lye tank made of titanium alloy for ultrasonic lye pre-cleaning, cleaning time: 15-20 minute...

Abstract

The invention discloses a manufacturing method of a black insulating film frame of an OGS (one glass solution) touch screen. The method comprises the following step that an inorganic black insulating film is manufactured by a vacuum sputtering deposition method, and a black light-shielding area meeting the requirement on a product is realized by combining stripping technology, wherein the transmittance rate is less than 0.1 percent, the resistivity is higher than 10 <11> omega. cm and the thickness is less than 0.5 micron. The quality and the appearance of an OGS product can be improved by the method, the reject rate caused in a production process is reduced, the production efficiency is improved, the other current technical conditions are not changed, the electric property effect is sable, and the problem that the light-shielding layer interferes with signal is solved.

Description

Technical field [0001] The invention relates to the field of touch screens, in particular to a method for manufacturing a black insulating film frame of an OGS touch screen. Background technique [0002] Capacitive touch screens are a new generation of touch screen products after resistive touch screens. Its performance has a qualitative leap over the previous generation products. It is not only responsive, supports multi-touch, and has a long life. The new generation of OGS products is a new development direction for capacitive touch screens. From a technical perspective, OGS technology has a simpler structure than the current mainstream G / G touch technology, which is lighter, thinner, and has better light transmittance; A piece of glass substrate and the laminating process help reduce production costs and improve product yield. [0003] At present, the common manufacturing methods of OGS touch screen modules are as follows figure 1 As shown, a black photosensitive material (BM) ...
