The novel integrated capacitive touch screen further comprises a step buffer layer gradually plated on the black film to reduce right-angle head gaps in the black film, and the ITO layer and the metal wire layer are gradually plated and formed with the step buffer layer as a foundation bed. Compared with the prior art, the novel integrated capacitive touch screen has the advantages of being simple and reasonable in structure, optimizing an one glass solution (OGS) structure, and improving the stability of a product and the like.
Description
Technical field
The utility model relates to photoelectricity industry design field, relates in particular a kind of novel all-in-one capacitive touch screen.
Background technology
Existing capacitive touch screen, the problem such as structure is varied, and cost requirement is also higher, is mainly reflected in etching technique and labyrinth, and materials'use is many.Under the market competition of fierceness, be derived integrated capacitor formula touch-screen OGS(one glass solution) structure 9, see also shown in Figure 1, it is integrated directly into conducting surface above the glass cover-plate 91, glass cover-plate 91 adopts the mode of printing that black film 92 is printed on above the glass cover-plate 91, and this ITO layer 93 and metal line layer 94 then are to be attached to above the glass cover-plate 91 that prints black film 92 in the mode of gradually plating.
OGS can reduce a sheet glass effectively, cost of labor in a slice transparent optical cement cost and the manufacture process, but the printing of existing structural design aspect black film 92, increased the difference in height of 4-10um, so so that there is the step drop in the gradually plating plane of ITO, cause easily the fracture of ITO layer 93, finally directly have influence on the reliability of product and functional.
In view of this, the inventor has this case to produce for the defects further investigation of existing capacitive touch screen then.
The utility model content
The purpose of this utility model is to provide a kind of novel all-in-one capacitive touch screen, and the ITO layer ruptures easily in the existing OGS structure condenser type touch-screen to solve, and has influence on reliability and functional problem of product.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of novel all-in-one capacitive touch screen comprises glass cover-plate, is printed on the black film on the glass cover-plate and gradually plates ITO layer and the metal line layer that is formed on glass cover-plate black film one side; Wherein, this novel all-in-one capacitive touch screen also is included in and gradually is plated to type on the black film to reduce the step cushion in the drop gap, right angle in the black film, and this ITO layer and metal line layer gradually are plated to type take the step cushion as bedding.
Further, this step cushion is silicon dioxide layer.
After adopting said structure, the integrated capacitor formula touch-screen that the utility model relates to, it is by being formed with a step cushion that can reduce drop gap in right angle in the black film, and mold ITO layer and metal line layer take the step cushion as substrate, it is more even so can effectively to improve ITO layer resistance, and has reduced the hidden danger of drop position ITO fracture.Compared with prior art, the utlity model has the effects such as simple and reasonable, optimization OGS structure and improving product stability.

ITO layer 3 metal line layer 4
OGS structure 9 glass cover-plates 91
Black film 92 ITO layers 93
Metal line layer 94.
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figure 2 to Figure 3, a kind of novel all-in-one capacitive touch screen 100 that the utility model relates to, it comprises glass cover-plate 1, black film 2, ITO layer 3 and metal line layer 4, this black film 2 is printed on the glass cover-plate 1,4 of this ITO layer 3 and metal line layers are to adopt the mode of gradually plating to be formed on glass cover-plate 1 black film 2 those sides, said structure is for OGS structure commonly used, so give unnecessary details no longer in detail.
Improvement of the present utility model is: this integrated capacitor formula touch-screen 100 also comprises step cushion 5, this step cushion 5 gradually is plated to type on black film 2, thereby play the effect that reduces the drop gap, right angle in the black film 2,4 of this ITO layer 3 and metal line layers gradually are plated to type take step cushion 5 as bedding.Preferably, this step cushion 5 is silicon dioxide layer.
Like this, the utility model is by being formed with a step cushion 5 that can reduce drop gap in right angle in the black film 2, and mold ITO layer 3 and metal line layer 4 take step cushion 5 as substrate, so can effectively improve ITO layer 3 resistance, make it more even, and reduced the hidden danger of drop position ITO fracture.Compared with prior art, the utlity model has the effects such as simple and reasonable, optimization OGS structure and improving product stability.
The forming process that the utility model relates to integrated capacitor formula touch-screen is: carry out the printing of black film 2 take glass cover-plate 1 as substrate, this black film 2 is controlled between the 4-8um, the outward appearance that forms human-computer interaction interface after the baking is beautified coating, then will adopt through the product of printing the mode of gradually plating to form the layer of silicon dioxide layer at black film 2, so this silicon dioxide layer can be filled up the stepped area of black film 2, as shown in Figure 3, and the formation camber line, this drop will become progressive form; 4 of last ITO layer 3 and metal line layers gradually plate take silicon dioxide layer as bedding and the operation such as Etching, make the OGS product.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
