Abstract
The invention provides a projection-type capacitive multi-touch screen comprising top ITO glass, optical cement and a bottom sensor. The top ITO glass forms a top cover for the touch screen, serves as a touch face for a user to touch, and also functions as an upper circuit part of the touch screen. The top ITO glass is composed of printed sliver paste and ITO-etched connected wires. The optical cement is used for adhering the top ITO glass and the bottom sensor. The bottom sensor is a conducting circuit board used for wiring and serves as a lower circuit part of the touch screen. The projection-type capacitive multi-touch screen is low in cost, small in thickness so that design space of a whole machine is more widened, and high in touch sensitivity.
Description
Technical field
The present invention relates to a kind of touch-screen, particularly a kind of projecting type capacitor multi-point touch panel.
Background technology
All be LENS+GLASS SENSOR structure or LENS+FILM SENSOR structure at every projection-type capacitive touch screen on the market at present.Concrete structure consists of: be made of top panel (GLASS or PET material)+optical cement+bottom SENSOR (the SENSOR material can be ITO FILM or ITO GLASS).
Each structure function is as follows:
1. top panel (GLASS or PET material)---the cover of touch-screen, the user puts tactile surface of contact;
2. optical cement---the high transparent solid-state or liquid glue of gluing panel and SENSOR;
3. the conducting wire plate of bottom SENSOR---PET or GLASS base material is used for wiring topology.
When the user points a little tactile panel, will electric capacity in parallel in the SESNOR circuit, thereby the total capacitance of SENSOR on this sweep trace changed.Special-purpose control IC will calculate according to the capacitance variations before and after the scanning coordinate position of touch point, is presented on the screen.
The defective of conventional art is: complex process, need high-end devices and laminated material, and affect production efficiency and production capacity, the price of the capacitance touch screen that processes is quite high.
Summary of the invention
In order to overcome the technical matters that exists in the prior art, the invention provides following technical scheme:
A kind of projecting type capacitor multi-point touch panel, described electric capacity multi-point touch panel is made of top ITO GLASS, optical cement, bottom SENSOR, described top ITO GLASS is the cover of touch-screen, the user puts tactile surface of contact, also is the upper circuit part of touch-screen simultaneously, by the printing of silver slurry and ITO etching in conjunction with wiring, described optical cement is used for bonding top ITO GLASS and bottom SENSOR, described bottom SENSOR is the conducting wire plate, is used for wiring topology, is the lower circuit part of touch-screen.
As the preferred technical solution of the present invention, the material of described bottom SENSOR is ITO FILM or ITO GLASS.
The contrast prior art, the beneficial effect that the present invention brings is: cost is lower; Whole screen thin thickness, larger expansion the design space of complete machine; Touch sensitivity is high.

Embodiment
The below is to elaborating preferred embodiment of the present invention by reference to the accompanying drawings, 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 made more explicit defining.
Extremely shown in Figure 2 such as Fig. 1, a kind of projecting type capacitor multi-point touch panel, described electric capacity multi-point touch panel is made of top ITO GLASS 1, optical cement 2, bottom SENSOR 3, described top ITOGLASS 1 is the cover of touch-screen, the user puts tactile surface of contact, also be the upper circuit part of touch-screen simultaneously, by silver slurry printing and ITO etching in conjunction with wiring, described optical cement 2 is used for bonding top ITO GLASS 1 and bottom SENSOR3, described bottom SENSOR 3 is the conducting wire plate, be used for wiring topology, be the lower circuit part of touch-screen.The material of described bottom SENSOR 3 is ITO FILM or ITO GLASS.
Projecting type capacitor multi-point touch panel of the present invention, holistic cost are compared other structures and have been descended significantly, and obtain on the result of use significantly to promote, and this is so that some middle and high end quality products also can enter the ranks of mass consumption.
The above; it only is one of the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
Claims (2)
