Abstract
The invention discloses a capacitive touch screen. The capacitive touch screen comprises a screen body, and is characterized in that the screen body is made of an ITOFILM (indium tin oxide film) material; one side of the screen body is adhered to a display through an adhesive layer. Furthermore, the adhesive layer is OCA (optical clear adhesive), silica gel or acrylic adhesive. A silver paste circuit and an ITO wiring circuit are printed on the screen body. According to the capacitive touch screen, the original multilayer structure is replaced by an ITOFILM; an LCD (liquid crystal display) or a TFT (thin film transistor) is adhered to the ITOFILM screen body through the OCA and the like; meanwhile, the silver paste circuit and the ITO circuit are printed on the upper surface of the ITOFILM screen body. By the design, the cost of the touch screen is greatly reduced; the overall thickness is smaller than that of other structures; the design space of an overall product is expanded greatly. In addition, the capacitive touch screen has a good using effect, and the service life is guaranteed.
Description
Technical field
The invention belongs to touch-screen field, specifically, relate to a kind of capacitive touch screen.
Background technology
Along with scientific and technological development, the progress of technology, touch-screen is widely used on the electronic products such as mobile phone, GPS, panel computer.Be all LENS+GLASS SENSOR structure at every projection-type capacitive touch screen on the market at present, LENS+FILM SENSOR structure.Said structure can be ITO FILM or ITO GLASS by top panel (GLASS or PET material), optical cement, bottom SENSOR(SENSOR material) form.
The material of top panel is GLASS or PET material, but the complex process of GLASS panel and SENSOR laminating needs high-end devices and laminated material, affect production efficiency and production capacity, so cause the touch-screen cost of GLASS panel high, complex process, price is also quite high.PET material is in outward appearance and touch texture and surperficial scratch-resistant hardness, more a bit weaker than GLASS panel, affects result of use and the serviceable life of touch-screen.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defect, provide a kind of simple in structure, cheap, result of use is good and the capacitive touch screen of long service life.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of capacitive touch screen, comprises screen body, the display be made up of ITO FILM material material; And be located between described screen body and display and the viscose glue laminating that both are bonded together.
Say further:
Described adhesive-layer is OCA optical cement, silica gel or acrylic glue.
Described screen body has been provided with silver slurry circuit and ITO wiring route.
Furthermore:
Described display is LCD or TFT display.
Owing to having adopted technique scheme, compared with prior art, one deck ITO FILM of the present invention substitutes original sandwich construction knot, and on ITO FILM screen body, sticks LCD or TFT by OCA optical cement etc., meanwhile, can be printed by silver slurry circuit and ITO wiring route can carry out in the above.Such design, significantly reduces the cost of touch-screen, and other the structure of Thickness Ratio of entirety is thin, has greatly expanded the design space of complete machine.In addition, result of use of the present invention is good, and has ensured serviceable life.
Below in conjunction with the drawings and specific embodiments, the invention will be further described simultaneously.
brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the present invention.
In figure: 1-display; 2-adhesive-layer; 3-shields body.
Embodiment
Embodiment 1:
As shown in Figure 1, a kind of capacitive touch screen, comprises screen body 3, and described screen body 3 is made up of ITO FILM material material.One side of screen body 3 is sticked display 1 by adhesive-layer 2.
In the present embodiment, substitute original sandwich construction by one deck ITO FILM and tie, and by sticking display on adhesive-layer ITO FILM screen body, meanwhile, can on ITO FILM, carry out being printed by silver slurry circuit and ITO wiring route.Such design, significantly reduces the cost of touch-screen, and other the structure of Thickness Ratio of entirety is thin, has greatly expanded the design space of complete machine.In addition, result of use of the present invention is good, and has ensured serviceable life.
Embodiment 2:
All the other are identical with described embodiment 1, and difference is, described adhesive-layer 2 is OCA optical cement, silica gel or acrylic glue.Meanwhile, on screen body 3, be printed with silver slurry circuit and ITO wiring route.
What in the present embodiment, adhesive-layer adopted is the one in OCA optical cement, silica gel or acrylic glue.Wherein, best embodiment is to adopt OCA optical cement.
Embodiment 3:
All the other are identical with described embodiment 1, and difference is, described display 1 is LCD or TFT display.
In the present embodiment, LCD or TFT display technology maturation, display effect is good, and cost is not high yet, is desirable display material.
The present invention is not limited to above-mentioned preferred implementation, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or akin technical scheme with the present invention, all belongs to protection scope of the present invention.
