Moreover, the upper surface of the base material is provided with a hardening processing layer and the lower surface of the base material is provided with printing decorative ink. The capacitive touch screen provided by the utility model has the characteristics of the capacitive touch screen, has low cost, is also flexible and has the advantages under the requirements of a curved surface panel product.

Description

The flexible capacitance type touch-screen
Technical field
The utility model 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 types, comprises resistance-type, condenser type, infrared and surface acoustic wave type touch-screen.
Past, because structure and the restriction that drives 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 the 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, the costing an arm and a leg of this two types of capacitive touch screens.In addition, consumption hopes 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 utility model provides the flexible capacitance type touch-screen, has the characteristics of capacitive touch screen, and cost is low, and secondly, flexibility has advantage under the requirement of curved surface panel product.To achieve these goals, the utility model has adopted following technical scheme:
The flexible capacitance type touch-screen is made up of flexible panel and flexible electric capacity inductive layer, and the base material of flexible panel is a polycarbonate, and the upper surface of base material is the cure process layer, and the lower surface of base material is a printed decoration printing ink.Flexible electric capacity inductive layer is the flexible and transparent conductive material with capacitive sensing pattern, can be that self-capacitance also can be mutual capacitance.
The flexible panel of flexible capacitance type touch-screen prepares process, and base material adopts large stretch of polycarbonate, and the upper surface at base material carries out cure process then, and lower surface is decorated the humour printing, and is last, cuts into needed small pieces, obtains panel.No matter be material cost or process aspect, its cost reduces.Secondly, after this flexible panel and the combination of flexible electric capacity inductive layer, it has soft characteristic, can satisfy the curved surface requirement.

Embodiment
In order to be described in detail the These characteristics of the utility model patent, advantage and principle of work below in conjunction with Figure of description and embodiment the utility model is done further explanation, but the scope that the utility model is protected are 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 chip for driving of controlling touch-screen and the FPC that connects touch-screen and chip for driving, and 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 is as shown in Figure 2, comprises that operation A is to E.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 a glass, and, be to need small pieces printing (like operation E), directly cause the cost of present capacitive touch screen high for proof strength.Fig. 3 is the synoptic diagram that present capacitive touch screen is used for the curved-surface structure product, is need curved surface be processed in face glass (1), and this will further improve the cost of touch-screen.
Fig. 4 is the flexible capacitance type touch-screen synoptic diagram of the utility model.The flexible capacitance type touch-screen is made up of flexible panel (3) and flexible electric capacity inductive layer (4).The base material that flexible panel (3) is is a polycarbonate, carries out cure process at the upper surface of base material, carries out the decorative ink printing at the lower surface of base material.Flexible electric capacity inductive layer (4) is the flexible and transparent conductive material with capacitive sensing pattern, can be that self-capacitance also can be mutual capacitance.Wherein self-capacitance and mutual capacitance mode, personnel are very familiar to its technology in the industry.The preparation section flow process of panel (3) comprises A ' to C ', and is 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, and efficient is high, and cost is low, and the cost of raw material own is low, therefore, can reduce the cost of capacitive touch screen.The flexible capacitance type touch-screen of the utility model, the base material that its panel (3) and capacitive sensing layer (4) all are all is a flexible material, therefore, it realizes the product curved surfaceization than being easier to, and satisfies market demands.
