Description

A kind of transparent three-dimensional touch screen structure

Technical field

This utility model is related to touch-control field, and in particular to a kind of transparent three-dimensional touch screen structure.

Background technology

Traditional capacitance plate has obtained extraordinary application with the development of smart mobile phone, while capacitance plate also enriches intelligence The input mode of energy terminal, it has obtained the welcome of users by which than keyboard in the way of more friendly.But capacitance plate is a kind of The touch technology of two dimension, Apple introduce pressure transducer and realize three-dimensional touch.Three-dimensional touch from first occur since receive Extensive attention is arrived, we not only can be able to input signal in two dimension, while the big of pressure can be passed through in third dimension It is little to be input into.But current pressure transducer is a kind of device detached with capacitance plate, and cannot be realized transparent.This and intelligence The lightening developing direction of energy terminal such as smart mobile phone mutually deviates from.

This utility model adopts a kind of transparent three-dimensional touch screen structure, and pressure transducer is combined with capacitive touch screen Into an entirety, this three-dimensional touch structure technology is fully transparent, can be fitted with display screen to aspect very much, while this Monolithic three-dimensional touch-control structure technology can meet the lightening developing direction of electronic product.

Utility model content

In view of this, the purpose of this utility model is to overcome defect of the prior art, there is provided a kind of transparent three-dimensional is touched Control screen structure；Include transparent substrates, the first transparency conducting layer, dielectric layer, the second transparency conducting layer, optical cement from lower to upper successively Layer, the 3rd transparency conducting layer and protective layer；Second transparency conducting layer, optical cement layer and the 3rd transparency conducting layer composition electric capacity Formula touch screen, the first transparency conducting layer and dielectric layer form pressure transducer.

Further, first transparency conducting layer, the second transparency conducting layer and the 3rd transparency conducting layer are by Graphene material Material is prepared from.

Further, the dielectric layer be PDMS, silica gel, the one kind in UV glue；The thickness of dielectric layer is 10-500 μm.

The beneficial effects of the utility model are：A kind of transparent three-dimensional touch screen structure disclosed in this utility model, can Pressure transducer and capacitive touch screen are combined into into an entirety, this three-dimensional touch structure technology be it is fully transparent, Can fit with display screen just very much, while this monolithic three-dimensional touch-control structure technology can meet the lightening development of electronic product Direction.

Description of the drawings

With reference to the accompanying drawings and examples this utility model is further described：

Fig. 1 is structural representation of the present utility model；

Fig. 2 is Making programme figure of the present utility model.

Specific embodiment

Fig. 1 is structural representation of the present utility model, and Fig. 2 is Making programme figure of the present utility model, as illustrated, this reality Apply the transparent three-dimensional touch structure in example；From lower to upper successively include transparent substrates 1, the first transparency conducting layer 2, dielectric layer 3, Second transparency conducting layer 4, optical cement layer 5, the 3rd transparency conducting layer 6 and protective layer 7；Second transparency conducting layer, optical cement Layer and the 3rd transparency conducting layer constitute capacitive touch screen, and the first transparency conducting layer and dielectric layer form pressure transducer；Second Transparency conducting layer 4, optical cement layer 5, the 3rd transparency conducting layer 6 can constitute mutual capacitance type capacitance plate, and mutual capacitance type capacitance plate can adopt CFF (COVER+FILM+FILM) structure is realized；Certainly, the first transparency conducting layer 2, the second transparency conducting layer 4 and the 3rd electrically conducting transparent Layer 6 forms the figure of Inductance and Capacitance matrix by laser ablation into compulsory figure, coordinates outside necessary circuitry to realize planar Touch-control, electric field emission layer of the 3rd transparency conducting layer 6 as touch screen, receiving layer of second transparency conducting layer 4 as touch screen, And then the second transparency conducting layer 4, optical cement layer 5, the 3rd transparency conducting layer 6 composition conventional capacitive touchscreen, realize planar Touch-control, the structure belong to prior art, will not be described here, and the dielectric layer 3 is prepared from using elastomeric material；Described The surface of one transparency conducting layer is by being laser-etched with the compulsory figure to form self-induction electric capacity；First transparency conducting layer 2 is being subject to Deforming upon during the power in normal to screen direction makes to be arranged at the first transparency conducting layer 2 as the matrix type reception electricity for receiving electric field Pole produces faradic current, is converted into pressure size signal, i.e. the first transparency conducting layer 2 as the 3rd according to faradic size The emission layer and receiving layer of dimension (i.e. pressure transducer)；When finger is contacted, signal transmitting layer sends electric field, finger contact area Different voltages or current signal are received in receiving layer (i.e. the second transparency conducting layer 4), so as to realize plane touch-control；And the One transparency conducting layer 2 and dielectric layer 3 can decomposition pressure formula sensor, when external power source is to the first 2 galvanization of transparency conducting layer, meeting Certain electric field is produced, the degree of finger down is different, and the electric current exported in causing this layer produces matrix type receiving electrode and produces sense Induced current changes, and then exports analysis, so as to realize pressure sensing.

In the present embodiment, first transparency conducting layer 2, the second transparency conducting layer 4 and the 3rd transparency conducting layer 6 are by stone Black alkene material is prepared from；Using the characteristics such as the good electric conductivity of Graphene, frivolous property, very high transmitance, flexibility, Cai Nengshi Existing flexible and transparent three-dimensional touch.

In the present embodiment, the dielectric layer is PDMS, silica gel, the one kind in UV glue；The thickness of dielectric layer is 10-500 μm, Reply effect of the thickness beneficial to dielectric layer, and mechanics transmission is sensitiveer；The present embodiment is preferably 250 μm of PDMS material (i.e. Polydimethylsiloxane), the dielectric layer can both be dielectric barrier, also can play a part of buffering during pushing, So that pressure is unlikely to destroy three-dimensional touch screen.

Finally illustrate, above example is only unrestricted to illustrate technical scheme, although with reference to compared with Good embodiment has been described in detail to the present invention, it will be understood by those within the art that, can be to the skill of the present invention Art scheme is modified or equivalent, and without deviating from the objective and scope of technical solution of the present invention, which all should be covered at this In the middle of the right of invention.
