Abstract
The utility model discloses a capacitance type touch screen which is formed by a tempered glass panel, a decoration layer, a comb-shaped transparent electric conduction pattern layer and a protection layer in an integrated mode, wherein the decoration layer, the comb-shaped transparent electric conduction pattern layer and the protection layer are successively stacked below the tempered glass panel, and the comb-shaped transparent electric conduction pattern layer is an array distribution transparent electric conduction film. As the capacitance type touch screen is formed by the tempered glass panel, the decoration layer, the comb-shaped transparent electric conduction pattern layer and the protection layer in an integrated mode, the decoration layer, the comb-shaped transparent electric conduction pattern layer and the protection layer are successively stacked below the tempered glass panel, and therefore glass of a sensing layer of a traditional capacitance type touch screen is omitted. In addition, the comb-shaped transparent electric conduction pattern layer is the array distribution transparent electric conduction film, and therefore the complex structure of electric conduction patterns of the traditional capacitance type touch screen is avoided. The touch screen structure is simplified, size is light and thin, material is saved, and cost is low.
Description
Technical field
The utility model relates to a kind of capacitive touch screen.
Background technology
Touch-screen is a kind of remarkable input equipment that improves man machine operation interface, have intuitively, simply, advantage efficiently.Touch-screen obtains a wide range of applications in many electronic products, such as mobile phone, PDA, multimedia, public information inquiry system etc.Touch-screen mainly contains following four classes, comprises resistance-type, condenser type, infrared type and surface acoustic wave touch screen.Wherein, capacitive touch screen is owing to have excellent performance, such as, there is not the mechanical motion wear problem in the screen, even and simple in structure, transmittance is high, the linearity good, dustproof, fire prevention, scratch resistantly also have a stable performance etc. in worst environment, has become the main flow in market.And the sharpest edges of capacitive touch screen are that it has the multi-point touch function, have greatly improved operating characteristic and the result of use of electronic product.
According to structure, the main flow capacitive touch screen is divided into two kinds at present, and a kind of is glass capacitive formula touch-screen, and another kind is the Film(film) capacitive touch screen.The structure of these two kinds of capacitive touch screens all is comprised of strengthened glass panel and capacitive sensing layer, and difference mainly is the capacitive sensing layer.The capacitive sensing layer of glass capacitive screen is the glass with specific capacitor induction pattern, and the capacitive sensing layer of Film capacitive touch screen is the flexible and transparent conductive material with specific capacitor induction pattern.Fig. 1 is the structural representation of conventional condenser touch-screen.This capacitive touch screen comprises tempered glass 1, optical lens gelatin 2 and capacitive sensing layer 3.In fact, capacitive touch screen also comprises the driving chip of controlling touch-screen and connects touch-screen and the flexible circuit board of driving chip that for the purpose of simplifying the description, these two parts do not illustrate in this application.The capacitive sensing layer of conventional condenser touch-screen comprises glass 4 and glass surface conductive pattern 5, but, this conductive pattern 5 is complexs of Various Complex structure, and it comprises vertical transparent conductive film, horizontal transparent conductive film, insulation, metal bridging and edge plain conductor etc.In order to obtain the conductive pattern of conventional condenser touch-screen, need a lot of operations of experience.For these traditional capacitive touch screens, combined by sandwich construction, cause complex structure, thickness very large, with high costs.
Summary of the invention
For overcoming the defective of prior art, the technical problems to be solved in the utility model has provided the capacitive touch screen that a kind of simplified structure, volume are frivolous, save material, cost.
The technical solution of the utility model is: this capacitive touch screen; it is formed by strengthened glass panel and the decorative layer, pectination transparent conductive patterns layer, the protective seam that stack gradually under strengthened glass panel, and pectination transparent conductive patterns layer is the pectination transparent conductive film of array distribution.
Because this capacitive touch screen is formed by strengthened glass panel and the decorative layer, pectination transparent conductive patterns layer, the protective seam that stack gradually under strengthened glass panel, thereby omitted the glass of the inductive layer of conventional condenser touch-screen; And because pectination transparent conductive patterns layer is the pectination transparent conductive film of array distribution, thereby avoided the labyrinth of the conductive pattern of traditional capacitance inductive layer; So simplified touch screen structure, volume frivolous, save material, cost.

Fig. 1 is the structural representation of traditional capacitive touch screen;
Fig. 2 is the structural representation according to capacitive touch screen of the present utility model.
Fig. 3 is the skeleton view according to pectination transparent conductive patterns layer of the present utility model.
Embodiment
The below is described in further detail the technical solution of the utility model.
Shown in Fig. 2-3; this capacitive touch screen; it is formed by strengthened glass panel 6 and the decorative layer 7, pectination transparent conductive patterns layer 8, the protective seam 9 that stack gradually under strengthened glass panel, and pectination transparent conductive patterns layer 8 is pectination transparent conductive films of array distribution.
Because this capacitive touch screen is formed by strengthened glass panel and the decorative layer, pectination transparent conductive patterns layer, the protective seam that stack gradually under strengthened glass panel, thereby omitted the glass of the inductive layer of conventional condenser touch-screen; And because pectination transparent conductive patterns layer is the pectination transparent conductive film of array distribution, thereby avoided the labyrinth of the conductive pattern of traditional capacitance inductive layer; So simplified touch screen structure, volume frivolous, save material, cost.
Preferably, strengthened glass panel is silicate glass panel or aluminate glass panel, and its thickness is 0.55 ~ 2mm.This strengthened glass panel is through chemical enhanced better, and its flexural strength surpasses 400MPa.
Preferably, decorative layer is BM resin decorating layer or ink lay.
Preferably, pectination transparent conductive patterns layer is ITO layer, wire netting, nano-silver layer, graphene layer and carbon nanotube layer.
Preferably, protective seam is film, coating or organic film.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment all still belong to the protection domain of technical solutions of the utility model.
