Fundamental purpose of the present utility model provides a kind of improved touch panel structure provided, it is that superimposition is provided with a plane formula decorative layer on this contact panel, making on the space of a whole page of contact panel own is that oneself possesses Decorative frame, therefore can obtain one when configuration is used and be the essence even curface, to bring up external form attractive in appearance and the good sense of touch of tool with casing.

The utility model time purpose provides a kind of improved touch panel structure provided, it is to be provided with most superincumbent layers such as comprising plane formula decorative layer and wearing layer in contact panel top superimposition, except that the abrasion performance of the working surface that can increase contact panel, scratch resistant damage usefulness, and can be by these most superincumbent layers to disperse pressing stress to what contact panel applied, avoid strain infringement, promote serviceable life the conductive layer of contact panel.

According to the present invention, a kind of improved touch panel structure provided, its tool one transparent pliability presses film, one top conducting film, an one below conducting film and a transparency carrier, this top conducting film is set on this basal surface that presses film, this below conducting film then is set at the upper surface of this flexible base plate, last, the below conducting film in the middle of the two with most separating balls will be separated from each other certain interval and subtend configuration, and be provided with the insulation cementing layer and will glue together each other and splice into a plate body in the periphery of this two conducting films configuring area, signal on this conducting film is sent to a soft winding displacement and a signal processing circuit by the silver-colored guide passage that electricity is connected on lateral edge, it is characterized in that: in aforementioned press the film upper surface in regular turn upwards superimposition be arranged to a rare plane formula decorative layer and a table coating, and this plane formula decorative layer is provided with the decoration architrave in the peripheral part, the central part of this decorative layer is a transparent region.

Wherein, the transparent region of aforementioned decorative layer central part also is a hollow out zone.

Wherein, the upper surface that also comprises this table coating has the dura mater coating.

The beneficial effects of the utility model are:

Of the present utility model improved touch panel structure provided, it is that superimposition is provided with a plane formula decorative layer on this contact panel, making on the space of a whole page of contact panel own is that oneself possesses Decorative frame, therefore can obtain one when configuration is used and be the essence even curface, to bring up external form attractive in appearance and the good sense of touch of tool with casing.

Of the present utility model improved touch panel structure provided, it is to be provided with most superincumbent layers such as comprising plane formula decorative layer and wearing layer in contact panel top superimposition, except that the abrasion performance of the working surface that can increase contact panel, scratch resistant damage usefulness, and can be by these most superincumbent layers to disperse pressing stress to what contact panel applied, avoid strain infringement, promote serviceable life the conductive layer of contact panel.

The utility model is not limited to the above form; clearly; with regard to haveing the knack of this technology personage; after the above-mentioned explanation of reference; more improvement and variation can be arranged, be with, all have in that identical creation spirit is following do relevant any modification of the present utility model or change; all must be included in the category of the utility model intention protection, and give Chen Ming.And will go on to say with a specific embodiment after being next to, further to illustrate character of innovation of the present utility model.

Embodiment

To shown in Figure 2, the contact panel of the utility model embodiment is to comprise a transparent pliability to press film 1, a top conducting film 2, a below conducting film 3, a transparency carrier 4, a plane formula decorative layer 5 and a table coating 6 as back accompanying drawing 1; This top conducting film 2 is set on this basal surface that presses film 1 in the mode of metal evaporation tin indium oxide (hereinafter to be referred as ITO), and this below conducting film 3 also is arranged on the upper surface of this substrate 4 by the mode with metal evaporation ITO, last, below conducting

film

2,3 in the middle of the two with most separating balls 42 will be separated from each other certain interval and subtend configuration, and in this two conducting film 2, the periphery of 3 configuring areas is provided with insulation cementing layer 43 and will glues together winding each other and become a transparent plate body, and the signal on these conducting films is to be sent to a soft winding displacement 45 and signal processing circuit (not being shown in drawing) by the silver-colored guide passage 44 that electricity is connected on lateral edge; In addition, press in aforementioned that superimposition is provided with this plane formula decorative layer 5 on the film 1, be provided with the decoration architrave 51 of special decorative pattern or color in the peripheral part of this plane formula decorative layer 5, to cover the peripheral architrave position in this contact panel inoperative zone, the central part of this decorative layer then is a transparent region 52; Again in the upper surface of aforementioned decorative layer 5 this table coating 6 that is sticked, and the working surface (being upper surface) in this table coating has dura mater coating (hard coat), for example be to utilize high rigidity UV cured coating coating former, make this working surface strengthen the anti-zoned anti-performance that stains that injures thus, remove covering of this this table coating 6 also can fix on the aforementioned decorative layer 5 print decorative pattern and the color of establishing, avoid fading or coming off.

Setting as said structure, contact panel of the present utility model will be glued at display screen the place ahead of electrical equipment and use, because oneself possesses Decorative frame is arranged on the space of a whole page of this contact panel own, therefore the cover of upholstery frame need not be set in addition in the edge, and because this contact panel is a smooth panel, therefore can obtain one after installing and be the smooth appearance surfaces of essence (as shown in Figure 3), so appearance and modeling can have globality aesthetic feeling and good sense of touch concurrently with casing; In addition, the utility model presses film 1 top in this and also has the slim sticking material material of multilayer such as decorative layer 5 and table coating 6, therefore contact panel carry out press running the time, aforementioned each superincumbent layer except that pressing this dispersion of stress appropriateness so long, also but negative catalysis presses the strain of ITO conducting film 2 of position (referring to Fig. 4, shown in Figure 5), to avoid this conductive film structure impaired, structure setting that again should the majority superincumbent layer also can not influence this susceptibility that presses operation or precision, because no matter be for single layer structure or sandwich construction, all same invariably a upper and lower displacement amount that presses this ITO conducting film 2 in the operation, but the significantly strain of negative catalysis ITO conducting film of structure setting that should the majority superincumbent layer, thereby the damage that reduces the ITO conductive film structure there is the great effect of improving.
