Embodiment 1

[0009] Prepare a glass substrate with a thickness of 0.2mm, and perform chemical strengthening treatment on it to enhance the strength of the glass substrate; (2) Coat a layer of ITO film with a thickness of 100mm on the lower surface of the glass substrate. A capacitive sensing structure composed of transparent conductive patterns on the lower surface is set in the touch ITO film layer, and a touch sensing layer pattern is made; (3) A BM layer with a thickness of 0.3um is electroplated on one side of the upper surface of the glass substrate, and customized (4) Coating a transparent layer with a thickness of 0.1um on one side of the upper surface of the BM layer, and doing customized anti-scratch treatment, anti-fingerprint treatment, and gap treatment; The ultra-thin front of the ultra-thin mobile phone is plated with BM's OGS touch screen.

Embodiment 2

[0011] Prepare a glass substrate with a thickness of 1.1mm, and perform chemical strengthening treatment on it to enhance the strength of the glass substrate; (2) Coat a layer of ITO film with a thickness of 300 μm on the lower surface of the glass substrate. A capacitive sensing structure composed of transparent conductive patterns on the lower surface is set in the touch ITO film layer, and a touch sensing layer pattern is made; (3) A BM layer with a thickness of 1.5um is plated on one side of the upper surface of the glass substrate and customized (4) Coating a transparent layer with a thickness of 1mm on one side of the upper surface of the BM layer, and doing customized anti-scratch treatment, anti-fingerprint treatment, and gap treatment; thus, the front electroplated BM The OGS touch screen can be used to touch the display screen of a computer.

Embodiment 3

[0013] Prepare a glass substrate with a thickness of 0.5mm, and perform chemical strengthening treatment on it to enhance the strength of the glass substrate; (2) Coat a layer of ITO film with a thickness of 200 µm on the lower surface of the glass substrate. A capacitive sensing structure composed of transparent conductive patterns on the lower surface is set in the touch ITO film layer, and a touch sensing layer pattern is made; (3) A BM layer with a thickness of 0.7um is plated on one side of the upper surface of the glass substrate and customized (4) Coating a transparent layer with a thickness of 0.5um on one side of the upper surface of the BM layer, and doing customized anti-scratch treatment, anti-fingerprint treatment, and gap treatment; BM's OGS touch screen can be used in mobile phones, tablets, navigators, etc.

Abstract

The invention discloses a method for manufacturing an OGS (one glass solution) touch screen by means of electroplating a BM (black matrix) on the front surface thereof. The method includes steps of (1), manufacturing a glass substrate and chemically enhancing and treating the glass substrate to improve the strength of the glass substrate; (2), plating a single-point touch ITO (indium tin oxide) film layer on the lower surface of the glass substrate; (3), electroplating BM layers on one side of the upper surface of the glass substrate; (4), coating a transparent layer on one side of the upper surface of each BM layer. The method has the advantages of high yield, low cost and simplicity in process.

Description

technical field [0001] The invention relates to a method for preparing a touch screen, in particular to a method for preparing an OGS touch screen with BM electroplated on the front. Background technique [0002] OGS (One Glass Solution) touch screen is a technology that directly forms ITO conductive film and sensors on the protective glass. A single piece of glass does double duty as both the protective glass and the touch sensor. The existing OGS touch screen adopts the structure of making BM (Black Matrix black matrix pattern) on the back of the glass and then making ITO lines. For example, the application number 201310170033.6 discloses a preparation method of OGS touch screen: making a light-shielding layer film on the surface of the glass cover; For the light-shielding layer film, realize the patterned light-shielding layer film frame by photolithography; make a transparent insulating layer; make a transparent conductive layer and pattern a transparent conductive patt...
