Abstract
The invention discloses a method for fabricating a white OGS (One Glass Solution) touch screen, and the fabricating method comprises the following steps of a) performing coating and shadow elimination to a glass substrate; b) silk-screen printing a first white ink layer in the frame region of the lower surface of the glass substrate; a steel wire gauze adopted during silk-screen printing is no less than 420 meshes and the printed white ink adopts screen printing ink which bears the temperature more than 230 degrees centigrade; c) silk-screen printing a second white ink layer on the lower surface of the first white oil ink layer; the steel wire gauze adopted during silk-screen printing is no less than 420 meshes and the printed white ink adopts screen printing ink which bears the temperature more than 230 degrees centigrade; d) fabricating an ITO layer in a transparent region at the bottom of the glass substrate through a yellow light process; the ITO layer is in a single-layer multiple-point caterpillar structure; e) silk-screen printing a gray oil ink layer on the lower surface of the second white oil ink layer; printing the white oil ink layer through the steel wire gauze with the high mesh number, thereby improving uniformity of the white oil ink layer and reducing thickness of the white oil ink layer; the white oil ink layer cannot become yellow by adopting heat-resistant screen printing ink after high-temperature processing, and thus the yield rate of the white OGS touch screen is increased.
Description
Technical field
The present invention relates to touch screen technology field, specifically a kind of method for making of white OGS touch screen.
Background technology
Along with the development of science and technology, intelligent electronic device, as mobile phone, panel computer, is seen everywhere in life, these equipment mostly use touch-screen to gather and the instrument of identifying information as it, touch-screen is frivolous with it, manipulates the advantages such as simple, obtains and applies more and more widely.
Wherein capacitive touch screen application is the most general, and the capacitance plate of main flow comprises two kinds: based on the capacitive touch screen of glass material and the capacitive touch screen based on Film material.Based on glass material capacitive touch screen because of its cost low, the advantage such as with short production cycle, in the ratio that the market share of capacitive touch screen is higher.
Simultaneously the touch-screen of OGS (One Glass Solution) structure realizes touch-screen cover plate and sensing function on one block of glass, save at least one sheet glass base material and bonding process, reduce production cost, shorten technological process, make touch-screen product more frivolous, therefore occupy the very large market advantage in touch-screen field.At present, on market, most of OGS touch screen is black touch-screen, and for white OGS touch screen, its white ink there will be the phenomenon of ink colors jaundice under the high temperature conditions, white OGS touch screen is caused to produce yield low, very difficult realization production in enormous quantities truly.
Summary of the invention
The object of the present invention is to provide a kind of method for making of white OGS touch screen, the method can reduce the manufacture difficulty of white OGS touch screen, avoids occurring yellowing phenomenon, improves the production yield of product.
The technical solution adopted for the present invention to solve the technical problems is:
A method for making for white OGS touch screen, comprises following steps:
A) carry out plated film to glass substrate to disappear shadow process;
B) at the rim area serigraphy first white ink layer of glass substrate lower surface, woven wire >=420 order that serigraphy adopts, white ink adopts the ink for screen printing of tolerance more than 230 DEG C temperature;
C) at the lower surface serigraphy second white ink layer of the first white ink layer, woven wire >=420 order that serigraphy adopts, white ink adopts the ink for screen printing of tolerance more than 230 DEG C temperature;
D) make ITO layer by the photic zone of gold-tinted technique bottom glass substrate, ITO layer is individual layer multiple spot caterpillar structure;
E) in the lower surface serigraphy gray oil layer of ink of the second white ink layer, woven wire >=360 order that serigraphy adopts.
Further, described glass substrate adopts the Asahi Glass two generation glass of 0.7mm.
Further, the inside edge of described second white ink layer extends out 0.5mm relative to the inside edge of the first white ink layer, and the second white ink layer and the first white ink layer form step in inner side.
The invention has the beneficial effects as follows, by the woven wire of high order number printing white ink layer, improve the homogeneity of white ink layer and reduce the thickness of white ink layer; Adopt high temperature resistant ink for screen printing that white ink layer can not be turned yellow after pyroprocessing, meanwhile, ITO layer adopts individual layer multiple spot caterpillar structure, only needs one gold-tinted technique, decrease the number of times of white ink layer contact high temperature, improve the production yield of white OGS touch screen.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is schematic diagram of the present invention.
Embodiment
As shown in Figure 1, the invention provides a kind of method for making of white OGS touch screen, comprise following steps:
A) carry out plated film to glass substrate 1 to disappear the penetrability of shadow process, reinforcing glass substrate, glass substrate 1 can adopt the Asahi Glass two generation glass of 0.7mm;
B) at the rim area serigraphy first white ink layer 2 of glass substrate 1 lower surface, woven wire >=420 order that the serigraphy of this step adopts, white ink adopts the ink for screen printing of tolerance more than 230 DEG C temperature;
C) at the lower surface serigraphy second white ink layer 3 of the first white ink layer 2, woven wire >=420 order that the serigraphy of this step adopts, white ink adopts the ink for screen printing of tolerance more than 230 DEG C temperature; The inside edge of the second white ink layer 3 extends out 0.5mm relative to the inside edge of the first white ink layer 2, and the second white ink layer 3 and the first white ink layer 2 form step in inner side;
D) make ITO layer 4 by the photic zone of gold-tinted technique bottom glass substrate 1, ITO layer 4 is individual layer multiple spot caterpillar structure;
E) in the lower surface serigraphy gray oil layer of ink 5 of the second white ink layer 3, white OGS touch screen is obtained, woven wire >=360 order that the serigraphy of this step adopts.
By the woven wire of high order number printing white ink layer, improve the homogeneity of white ink layer and reduce the thickness of white ink layer; The ink for screen printing that first white ink layer 2 and the second white ink layer 3 adopt is preferably the ink for screen printing of tolerance 230 ~ 250 DEG C of temperature, white ink layer can not be turned yellow after pyroprocessing, simultaneously, ITO layer 4 adopts individual layer multiple spot caterpillar structure, only need one gold-tinted technique, decrease the number of times of white ink layer contact high temperature; Second white ink layer 3 and the first white ink layer 2 form step in inner side, reduce the climbing difficulty of ITO layer, thus reduce the difficulty of touch-screen process for integrally manufacturing; Gray oil layer of ink adopts the woven wire printing of medium above order number, ensures the overall obscurity of OGS touch screen and the uniformity coefficient of overall ink; Adopt this method can improve the production yield of white OGS touch screen.
