Abstract
The invention provides a flexible capacitive touch screen which comprises a panel and a capacitive sensing layer, wherein the panel is prepared by polycarbonate in the process that the upper surface of the polycarbonate is subjected to hardening treatment, the lower surface of the polycarbonate is printed with decorative printing ink; and the capacitive sensing layer is a flexible transparent conductive material provided with capacitive sensing patterns. The flexible capacitive touch screen has characteristics of a capacitive touch screen, is low in cost and has the advantages of flexibility under the requirement of a curved surface panel product.
Description
Technical field
The present invention relates to 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 has obtained to use widely 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 and surface acoustic wave type touch-screen.
Past, because structure and drive the restriction of cost, and many-sided shortcoming such as touch-control distortion, the utilization scope of capacitive touch screen is very narrow.Afterwards, owing to updating of structure and signal processing technology, capacitive touch screen constantly rose, and typical case's representative is that Apple releases iPhone mobile phone and iPad panel computer.And the sharpest edges of capacitive touch screen are that it has the multi-point touch function, have improved operating characteristic and the result of use of electronic product greatly.
According to structure, the capacitive touch screen of main flow is divided into two kinds at present, and a kind of is the glass capacitive touch screen, and another kind is the Film capacitive touch screen.The structure of these two kinds of capacitive touch screens all is made up of face glass and capacitive sensing layer, and difference mainly is the capacitive sensing layer.The capacitive sensing layer of glass capacitance plate is the glass with capacitive sensing pattern, and the capacitive sensing layer of Film capacitive touch screen is the flexible and transparent conductive material with capacitive sensing pattern.Traditional relatively resistance screen, this two classes capacitive touch screen expensive.In addition, consumption wishes that capacitive touch screen has curved surfaceization.In order to satisfy the curved surface requirement, the cost of capacitive touch screen is higher at present.Need to develop the low-cost demand that a kind of new technology satisfies touch-screen, secondly curved surface demand.
Summary of the invention
The invention provides the flexible capacitance type touch-screen, have the characteristics of capacitive touch screen, and cost is low, secondly, flexibility has advantage under the requirement of curved surface panel product.To achieve these goals, the present invention has adopted following technical scheme:
The flexible capacitance type touch-screen, formed by panel and capacitive sensing layer, wherein panel is by the polycarbonate upper surface cure process and that carry out the printing of lower surface decorative ink, the capacitive sensing layer is the flexible and transparent conductive material with capacitive sensing pattern, and its capacitance induction principle can be that self-capacitance also can be mutual capacitance.
The panel preparation process of flexible capacitance type touch-screen is, large stretch of polycarbonate, and the upper surface cure process, the lower surface printing cuts into needed small pieces then, obtains panel.No matter be material cost or process aspect, its cost reduces.Secondly, after this panel and the combination of capacitive sensing layer, it has soft characteristic, can satisfy the curved surface requirement.

Embodiment
In order to be described in detail the These characteristics of patent of the present invention, advantage and principle of work, the present invention is described further below in conjunction with specification drawings and specific embodiments, but the scope that the present invention protects is not limited thereto.
Fig. 1 is the structural representation of present capacitive touch screen.Capacitive touch screen comprises face glass (1) and capacitive sensing layer (2).Reality, capacitive touch screen also comprise the driving chip of controlling touch-screen and connect touch-screen and the flexible circuit board of driving chip that these two parts are not shown in this patent.For present capacitive touch screen, in order to guarantee the intensity of touch-screen, face glass (1) is to adopt tempered glass, and its preparation flow comprises that operation A is to E as shown in Figure 2.The detailed process of operation is, A---glass raw material, B---glass raw material cuts into small pieces, C---and small pieces carry out sharp processing, D---chemical enhanced formation tempered glass, E---tempered glass lower surface carry out repeatedly decorative ink printing and obtain face glass (1).In the preparation process of reality, also have other a lot of aided processes, here do not list.Because the material of face glass (1) is glass, and for proof strength, be to need small pieces printing (as operation E), directly cause the cost of present capacitive touch screen high.Fig. 3 is the synoptic diagram that present capacitive touch screen is used for the curved-surface structure product, is face glass (1) need be processed into curved surface, and this will further improve the cost of touch-screen.
Fig. 4 is flexible capacitance type touch-screen synoptic diagram of the present invention.The flexible capacitance type touch-screen, formed by panel (3) and capacitive sensing layer (4), wherein panel (3) is by the polycarbonate upper surface cure process and carry out the decorative ink printing at lower surface, capacitive sensing layer (4) is the flexible and transparent conductive material with capacitive sensing pattern, and its capacitance induction principle can be that self-capacitance also can be mutual capacitance.Wherein self-capacitance and mutual capacitance principle, personnel are very familiar to its technology in the industry.The preparation section flow process of panel (3) comprises that A ' is to C ', as shown in Figure 5.The detailed process of operation is A '---have the polycarbonate starting material of upper surface cure process, the lower surface of B '---large stretch of polycarbonate prints various decorative inks, C '---cuts into small pieces acquisition panel (3).This panel (3) can adopt large stretch of printing, the efficient height, and cost is low, and the cost of raw material own is low, therefore, can reduce the cost of capacitive touch screen.Flexible capacitance type touch-screen of the present invention, the base material that its panel (3) and capacitive sensing layer (4) all are all is flexible material, therefore, it realizes the product curved surfaceization than being easier to, and satisfies market demands.
