A kind of integrated type capacitive touch screen
Technical field
The utility model relates to touch-screen production field, particularly a kind of integrated type 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 complex structure, and materials'use is many.Under fierce market competition, the integrated type touch-screen OGS(one glass solution being derived) structure, as shown in Figure 1, it is integrated directly into conducting surface on glass cover-plate 11, glass cover-plate 11 adopts the mode of printing that black light resistance or ink 12 are printed on glass cover-plate 11, and then the mode with sputter is attached on the glass cover-plate 11 that prints black light resistance or ink 12 by ITO line layer 13.OGS can reduce the cost of labor in a sheet glass, a slice transparent optical cement cost and manufacture process effectively, but in existing structural design, black light resistance or ink have increased by a difference in height, this difference in height easily because the burr of ink or black light resistance and out-of-flatness etc. cause ITO circuit to disconnect, causes the loss of function yield in climbing place 14.The touch screen structure of this kind of structure must first have been finished ink or black light resistance layer simultaneously, then removes to run gold-tinted processing procedure and make ITO line layer.Owing to will passing through gold-tinted processing procedure, therefore higher to the acid and alkali-resistance requirement of ink and black light resistance, therefore on material is selected, be subject to limitation, and increase cost.
Summary of the invention
The purpose of this utility model is to provide a kind of and can effectively addresses the above problem, and improves product yield, the integrated type capacitive touch screen reducing production costs.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of integrated type capacitive touch screen, comprise glass cover-plate, ITO line layer, and be printed on ink or black light resistance on glass cover-plate; It is characterized in that: described ink or black light resistance are printed on glass cover-plate front, described ITO line layer is formed on glass cover-plate reverse side by running gold-tinted sputter.
Preferably, for guaranteeing touch feeling and the protection ink of user when using touch-screen, described ink or black light resistance are provided with a protective seam.
Adopt technique scheme, integrated type capacitive touch screen described in the utility model, by ink or black light are hindered to the two sides of being located at respectively glass cover-plate with ITO line layer, can avoid because the yield loss of the ITO broken string that climbing problem causes; The preparation process of this structure order can have been made after ITO line layer for first glass cover-plate runs gold-tinted simultaneously, then does ink layer to considering resistance to acids and bases in the selection of ink, has reduced cost.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 2, a kind of integrated type capacitive touch screen, comprises glass cover-plate 21, ITO line layer 22, is printed on ink or black light resistance 23 on glass cover-plate 21; It is positive that ink or black light resistance 23 are printed on glass cover 21 plates, and described ITO line layer 22 is formed on glass cover-plate 21 reverse side by running gold-tinted sputter.
As shown in Figure 3, for guaranteeing touch feeling and the protection ink of user when using touch-screen, described ink or black light resistance 23 are provided with a protective seam 24.
The utility model, by ink or black light are hindered to the two sides of being located at respectively glass cover-plate with ITO line layer, can be avoided because the yield loss of the ITO broken string that climbing problem causes; The preparation process of this structure order can have been made after ITO line layer for first glass cover-plate runs gold-tinted simultaneously, then does ink layer to considering resistance to acids and bases in the selection of ink, has reduced cost.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; within not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
