Embodiment Construction

[0032] In order to facilitate the understanding of those skilled in the art, the principle of the present invention will be further described in detail below in conjunction with specific embodiments.

[0033] Such as Figure 1-Figure 5 As shown, the present invention discloses a method for manufacturing an OGS touch screen. The method for manufacturing an OGS touch screen includes the following steps:

[0034] (1) For the glass substrate 1, a traditional cleaning machine can be used. First, use a water solvent with a cleaning agent content of about 5% to brush twice through the hair wheel, and then perform ultrasonic cleaning with DI water (ion pure water) , and then brushed with DI water, rinsed, and dried;

[0035] (2) Vacuum sputtering coats a layer of niobium oxide Nb2O5 of about 70 - 150 Å on the back of the cleaned and dried glass substrate 1 as an electrode shadow removal layer;

[0036] (3) Then vacuum coat the back of the erasing layer, set the temperature at 400-50...

Abstract

The invention discloses a manufacturing method of an OGS touch screen. The manufacturing method comprises the following steps: a. a shadow-removing layer is sputtered on the back of a glass substrate through the method of vacuum coating; b. a conductive layer is sputtered on the back of the shadow-removing layer through the method of vacuum coating; c. an electrode pattern and driving routings are manufactured through an exposure process or a silkscreen process; d. an ink layer for covering the routings is printed on the back of the glass substrate, and thus an outer frame pattern is formed; e. a conductive ink layer is printed on a blank area of a conductive metal foot; f. silver pasted lines are printed on the conductive ink layer; g. the shape of the touch screen is processed, PFC lead feet are pasted on the silver pasted lines, and thus the touch screen is finished. According to the manufacturing method of the OGS touch screen, the conductive layer is arranged on the surface of the glass substrate directly, the conductive ink is conducted, therefore, the problems of breakage of the coating film layers caused by coating film steps and breakage of the FPC hot-pressed conducting layer are solved, the gluing yield is improved, and the touch screen is durable.

Description

technical field [0001] The invention relates to a touch screen, in particular to a method for manufacturing an OGS touch screen. Background technique [0002] In the capacitive touch screen market, the main technology of the projected capacitive touch panel for multi-touch applications is composed of Cover Lens (cover plate) + Sensor (functional chip). At present, a new structure OGS (One Glass Solution) appears on the market, which is characterized by integrating Cover Lens and Sensor into a piece of glass. This saves a piece of glass, greatly reduces product cost, and also makes the touch screen with higher transmittance and thinner. [0003] At present, the production method of OGS mainly includes the first step: glass cleaning and the second step: black frame production. In the process of black frame production, the exposure operation method mainly uses organic photoresist as the material at present. This process requires the coating thickness of the black frame materi...
