Abstract
The invention provides a novel flat touch screen, which comprises a top PET (Polyethylene Terephthalate) panel, optical cement, an upper ITO (Indium Tin Oxide) FILM, an adhesive, a separation points and lower irregularly-shaped ITO GLASS, wherein the small formed ITO FILM is firstly attached to the ITO GLASS and then the top PET panel is attached to the ITO FILM. The novel flat touch screen has the advantages of simpler and more convenient structure, high strength requirement, relatively low cost, high production efficiency and product structure not affecting the appearance after assembly of a shell.
Description
Technical field
The present invention relates to touch-screen, particularly a kind of novel pure plane touch screen.
Background technology
At present at the pure flat class touch-screen of every special-shaped profile on the market two kinds of forms are arranged:
First kind: four-layer structure (popular saying) is actual to be eight layers of structure, namely is made of the special-shaped support glass in top PET panel+optical cement+top ITO FILM+ viscose glue+dot interlace+bottom ITO FILM+ optical cement+bottom.
Each structure function:
1. top PET panel--the cover of-touch-screen, the user puts tactile surface of contact
2. optical cement--the high transparent glue of-gluing panel and top ITO FILM
3. the conducting wire plate of top ITO FILM---PET base material is used for wiring topology
4. viscose glue--the glue of-gluing top ITO FILM and bottom ITO FILM
5. dot interlace---being printed on the little site on ITO FILM surface, bottom, point rises when touching operation and supports and insulating effect
6. the conducting wire plate of bottom ITO FILM---PET base material is used for wiring topology
7. optical cement--the high transparent glue of-gluing special-shaped support glass in bottom and bottom ITO FILM
8. the special-shaped support glass in bottom---be used for supporting the high transparent toughened glass of whole touch screen
In second: three layers of patch structure (popular saying) are 6 layers actually, are made of top PET panel+optical cement+top ITO FILM+ viscose glue+viscose glue+bottom ITO GLASS+ patch
Each structure function:
1. top PET panel--the cover of-touch-screen, the user puts tactile surface of contact
2. optical cement--the high transparent glue of-gluing panel and top ITO FILM
3. the conducting wire plate of top ITO FILM---PET base material is used for wiring topology
4. the glue of the special-shaped ITO GLASS in viscose glue---gluing top ITO FILM and bottom
5. dot interlace---being printed on the little site on bottom ITO FILM (GLASS) surface, point rises when touching operation and supports and insulating effect
6. the conducting wire plate of bottom ITO GLASS---glass baseplate is used for wiring topology
7. patch---pad is filled up the special-shaped part of screen body in PET panel bottom
Basic functional principle:
When the user puts when touching panel, panel and top ITO FILM sink, touch bottom ITO FILM or ITO GLASS after, can produce an electric signal, be carried in the position that application-specific integrated circuit on the mainboard can detect this signal and calculate this contact this moment, is presented on the screen.
The drawback of the pure plane touch screen that four-layer structure is novel:
1. complex structure influences and produces yield
2. the number of plies is tired many, the whole screen of influence transmittance
3. because of the many thickness of the number of plies also increase thereupon, the design space of having limited complete machine greatly
The drawback of the pure plane touch screen that three layers of patch structure is novel:
Because having adopted the patch filling, screen body bulk strength weakens, and whole screen installation back PET face version occur easily because of fill up height can't 100% coupling casing at the impression of edge joint position appearance, influence outward appearance.
Summary of the invention
In order to overcome the technical matters that exists in the prior art, better improve and produce yield, improve whole screen transmittance, expand the complete machine design space, and the casing suitability, the invention provides a kind of novel pure plane touch screen, its structure is easier, requirement of strength height, but cost is cheap relatively, the higher and product structure that do not influence outward appearance behind the installation shell of production efficiency.
To achieve these goals, the invention provides following technical scheme:
A kind of novel pure plane touch screen comprises
Top PET panel: the cover of touch-screen is used for the user and puts tactile surface of contact;
Optical cement: the high transparent glue of gluing top PET panel and top ITO FILM;
The conducting wire plate of top ITO FILM:PET base material is used for wiring topology;
Viscose glue: the glue of the special-shaped ITO GLASS in gluing top ITO FILM and bottom;
Dot interlace: be printed on the little site on bottom ITO FILM (GLASS) surface, point rises when touching and supports and insulating effect;
The special-shaped ITO GLASS:GLASS CNC of elder generation in bottom cuts sputter ITO after the required profile, does the conducting wire plate of strengthening the glass baseplate of handling afterwards again; Be used for wiring topology;
ITO FILM and the ITO GLASS of small pieces moulding are fitted earlier, stick on top PET panel at ITO FILM then.
The beneficial effect that the present invention brings is:
1. than four-layer structure remarkable advantages is arranged on whole screen transmittance, transmittance has risen to 85% from 75%.
2. on whole screen thickness, than four-layer structure remarkable advantages is arranged, reduce on year-on-year basis 0.25MM or more than.
3. than four-layer structure remarkable advantages is arranged on whole screen manufacturing process and yield, yield has promoted 10% on year-on-year basis.
4. on integrated cost, than four-layer structure remarkable advantages is arranged.
5. than three layers of patch structure remarkable advantages is arranged in intensity and installation effect, because its profile can be made abnormally-structured, mobile phone or other equipment casings so can better fit, it is more personalized to make it product, more meet modern aesthetic, comprise that some handheld terminal profiles can accomplish more to meet ergonomics.

Embodiment
Below to by reference to the accompanying drawings preferred embodiment of the present invention being elaborated, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
To shown in Figure 2, a kind of novel pure plane touch screen comprises as Fig. 1
Top PET panel 1: the cover of touch-screen is used for the user and puts tactile surface of contact;
Optical cement 2: the high transparent glue of gluing top PET panel 2 and top ITO FILM 4;
The conducting wire plate of top ITO FILM 3:PET base material is used for wiring topology;
Viscose glue 4: the glue of the special-shaped ITO GLASS 6 in gluing top ITO FILM3 and bottom;
Dot interlace 5: be printed on the little site on ITO FILM surface, bottom, point rises when touching and supports and insulating effect;
