Embodiment

Be depicted as the preferred embodiment of the utility model like Fig. 1 to Fig. 6 D; And in following examples, will explain as case with capacitance type touch-control panel; But the utility model practical range is not limited to use capacitance type touch-control panel; For example use electric resistance touch-control panel or electromagnetic touch-control panel also applicable, close first Chen Ming.

In first embodiment, this contact panel structure from top to bottom comprises on one transparency carrier 10, a color frame 20, a touch-control sensor 30 and transparency carrier 40 once in regular turn; Wherein, This upper and lower transparency carrier the 10, the 40th adopts to have the transparent material of essence; Its material is to be selected from sheets of glass or other various bendable thin plates; For example: polycarbonate (PC), polyester (PET), polymethylmethacrylate (PMMA) or cycloolefin co-polymer (C0C) ... etc.; But the material ranges of implementing is not exceeded with previous materials, and all kinds of soft or rigid, transparent or semitransparent substrates all are suitable for, and particularly this upper and

lower transparency carrier

10,40 can use light sheet material identical or inequality.And the composition of this color frame 20 can be printing ink, color photoresistance, organic material or inorganic material; But enforceable material ranges is not as limit; Previous materials is arranged at the basal surface peripheral part of transparency carrier 10 on this by technological means such as printing, coating, metal evaporations; Only practical range does not exceed with above-mentioned technological means, the opaque film that this color frame 20 forms about the about 1 μ m of a thickness.This touch-control sensor 30; Is embodiment at this to select the capacitance touching control inductor for use; And it comprises an X axle inductive layer 30a, a Y axle inductive layer 30b and an insulation course 30c; This insulation course 30c is located between X, Y axle inductive layer 30a, the 30b two inductive layers is provided with being insulated, and makes X, Y axle inductive layer ground connection and be connected to a control circuit (not being shown in figure) respectively, and aforementioned

inductive layer

30a, 30b are to use tin indium oxide (ITO) film; This insulation course 30c is the viscose thin layer of an insulativity, and

inductive layer

30a, 30b and insulation course 30c are the transparent thin layer of essence; Again the X axle inductive layer 30a up of this touch-control sensor 30 directly processing and fabricating aforementioned be provided with color frame 20 on the first type surface of transparency carrier 10; And this touch-control sensor 30 below Y axle inductive layer 30b also be set directly at the upper major surface of aforementioned down transparency carrier 40, carry out applying one on top of another in two

inductive layer

30a, 30b again at a distance from establishing this insulation course 30c then; Be configured in the lower face of aforementioned transparency carrier 10 and color frame 20 because of this touch-control sensor 30; And make the Communication signal wire part at its edge just can correspondence be arranged at aforementioned color frame below; So but this color frame 20 of mat reaches the purpose of beautifying panel appearance to cover the Communication signal wire part at this touch-control sensor edge.

The contact panel of forming according to aforementioned components is to utilize a cementing layer 91 and paste and be assemblied in a display screen 92 the place aheads and use (detailed as shown in Figure 2), lets the user can see through indication on these display screen 92 pictures to touch or to push on this panel ad-hoc location to carry out the signal input; And during input operation; Finger or conductor by the user touch the moment on this contact panel surface; This capacitance touching control inductor 30 will produce the electric capacity signal of an induction; Can confirm the position of finger or conductor then by the variation that detects the sensor signal value, reach the purpose of signal input in view of the above.The previous embodiment of the utility model and the contact panel structure of convention are compared; Can find; The color frame 20 of the utility model, inductive layer 30a up are formed directly on the transparency carrier 10; Below inductive layer 30b also directly be produced on down on the transparency carrier 40, and then, can omit the substrate of convention contact panel and the comprehensive gluing processing procedure between facing board and each inductive layer with the two applying of insulating; Therefore not only can cut down finished cost, improve the product yield, have the advantage of promoting the product optical characteristics and helping the design of product thin type simultaneously concurrently.

Moreover; Follow the basic structure of aforementioned first embodiment can be in response to this contact panel in different service conditions and the change of making adjustment; For example be: in second embodiment that Fig. 3 showed; Be according to the structure of aforementioned first embodiment and its down the lower surface of transparency carrier 40 ground plane 50 is set again; This ground plane 50 can adopt transparent conductive material to process, for example: and materials such as tin indium oxide (ITO) or indium zinc oxide, but this ground plane 50 of mat keeps the interference of earthing potential counterchecking electromagnetic wave noise to this this touch-control sensor 30.In the 3rd embodiment that Fig. 4 A is shown; Be transparency carrier 10 and color frame 20 according to the structure of aforementioned first embodiment and on this first type surface and this touch-control sensor above a protective clear layer 60 is set between the inductive layer 30a; With enhancement coincide the planarization pasted, avoid the residual problem of gassing at the edge of this color frame 20; And these protective seam 60 materials can be selected from materials such as silicon nitride, silicon dioxide, type photoresistance, but the material ranges of implementing is not exceeded with previous materials; In Fig. 4 B, show the another kind combination style of the 3rd embodiment, except that being provided with protective clear layer 60, more the lower surface of transparency carrier 40 is provided with a ground plane 50 under it.

In addition; The 4th embodiment that is shown at Fig. 5 A; Be according to the structure of aforementioned first embodiment and be provided with a function film 70 at the upper surface of this transparency carrier 10; This function film 70 can be one deck sprayed film or hard coating film, uses the reflecting rate that reduces the contact panel surface, or promotes the hardness and the scrape abrasion resistance of panel surface; This function film 70 can also be the film that one deck possesses the light regulatory function again; For example be to regulate film, use the looking forward or upwards property of promoting this display screen by one of optical thin films such as side's property film such as polarization film, phase-contrast film or optics or the laminated light that combines of the film more than two kinds; Other combination style that in Fig. 5 B to Fig. 5 D, shows the 4th embodiment except that being provided with function film 70, also increasing respectively and is provided with one of protective clear layer 60, ground plane 50, and be provided with simultaneously protective clear layer 60 and ground plane 50 the two.

The utility model is not limited to the above form; Clearly with reference to after the above-mentioned explanation; The improvement and the variation of more how technological isotropism can be arranged, and this for example is: can be according to the structure of aforementioned arbitrary embodiment, and this transparency carrier 10 is except the configuration that can use the plane formula plate body; Also can be in response to the different demands of installing and using occasion of contact panel; Adopt one to have the plate body of curved surfaces or the plate body of other various non-planar (shown in Fig. 6 A to Fig. 6 D) and change ..., and these are more established and all reach and the same or similar usefulness of previous embodiment, so should be identical with the true matter of the utility model aforementioned techniques; Therefore, all have in following any modification or change of making relevant the utility model of identical creation spirit, all must be included in the category of the utility model intention protection.
