Abstract
The invention discloses a capacitive touch screen which is integrally formed by a tempered glass panel, an adornment layer, a comb-shaped transparent conductive pattern layer and a protective layer, wherein the adornment layer, the comb-shaped transparent conductive pattern layer and the protective layer are sequentially stacked under the tempered glass panel, wherein the comb-shaped transparent conductive pattern layer is a comb-shaped transparent conductive film distributed in an array way. As the capacitive touch screen is integrally formed by the tempered glass panel as well as the adornment layer, the comb-shaped transparent conductive pattern layer and the protective layer which are sequentially stacked under the tempered glass panel, glass of a sensing layer of the conventional capacitive touch screen is omitted; the comb-shaped transparent conductive pattern layer is the comb-shaped transparent conductive film distributed in the array way, so that a complex structure of conductive patterns of the conventional capacitive sensing layer is avoided; and therefore, the capacitive touch screen is light in weight and thin in size and has the advantages of simplifying the structure, saving materials and reducing the cost.
Description
Technical field
The present invention 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 problem to be solved in the present invention has provided the capacitive touch screen that a kind of simplified structure, volume are frivolous, save material, cost.
Technical scheme of the present invention 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 invention.
Fig. 3 is the skeleton view according to pectination transparent conductive patterns layer of the present invention.
Embodiment
The below is described in further detail technical scheme of the present invention.
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 invention; be not that the present invention is done any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment all still belong to the protection domain of technical solution of the present invention.
