Abstract
The utility model provides a capacitance type touch screen which is composed of a top polyethylene glycol terephthalate (PET) panel, optical cement and a bottom sensor, wherein the top PET panel is a surface cover of the touch screen and a contact surface used for point contact of a user, the top PET panel and the bottom sensor are adhered through the optical cement, and the bottom sensor is a conductive wire circuit board made of PET or glass base materials and is used for distribution of circuits. The capacitance type touch screen achieves structure simplicity and convenience, and is low in production cost, high in the yield of good products, large in productivity, and suitable for mass requirements of mid-range consumers.
Description
Technical field
The present invention relates to a kind of touch-screen, particularly a kind of capacitive touch screen.
Background technology
All be glass structure at every projection-type capacitive touch screen panel on the market at present, the projection-type capacitive touch screen structure is made of top glass panel+optical cement+bottom sensor (the sensor material can be ITO film or ito glass).
Each structure function:
1. top glass panel---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. bottom sensor---the conducting wire plate of PET or glass baseplate is used for wiring topology
Basic functional principle:
When the user points a little tactile panel, will electric capacity in parallel in sensor 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 drawback of glass panel structure projection-type capacitive touch screen:
The complex process that face glass and sensor are fitted needs high-end devices and laminated material, affects production efficiency and production capacity, and because the cost of face glass is high, complex process is so the capacitance touch screen price that is processed into is also quite high.
The advantage of glass panel structure projection-type capacitive touch screen:
Because glass panel structure, so better on outward appearance transmittance and touch texture.
Summary of the invention
In order to overcome the technical matters that exists in the prior art, better improve and produce yield, reduce cost, expand the overall design space, it is easier to the invention provides a structure, and production cost is cheaper, yield is higher, and production capacity is larger, is more suitable for the structure of middle-end consumer's heavy demand.
To achieve these goals, the invention provides following technical scheme:
A kind of capacitive touch screen, consisted of by top PET panel, optical cement and bottom sensor, described top PET panel is the cover of touch-screen, be used for the user and put tactile surface of contact, described optical cement gluing face top PET panel and bottom sensor, described bottom sensor is the wire line plate of PET or sensor substrate, is used for wiring topology.
The beneficial effect that the present invention brings is:
1. on cost, than glass panel structure obvious advantage is arranged.
2. than glass panel structure obvious advantage is arranged on whole screen thickness, PET is the thinnest can to accomplish 0.188MM, and the present the thinnest 0.4MM that generally can only arrive of glass, and expensive.
3. on whole screen manufacturing process and yield, than glass panel structure obvious advantage is arranged, need not special-purpose abutted equipment, manually-operated and can satisfy the applying requirement, yield can reach more than 90%.

Fig. 2 is structure right view of the present invention
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 capacitive touch screen, consisted of by top PET panel 1, optical cement 2 and bottom sensor 3, described top PET panel 1 is the cover of touch-screen, be used for the user and put tactile surface of contact, described optical cement 2 gluing face top PET panel 2 and bottom sensor 3, described bottom sensor 3 is the wire line plate of PET or glass baseplate, is used for wiring topology.
The present invention is because adopted the PET panel construction, the holistic cost of projection-type capacitive touch screen has descended significantly, this is so that vast low and middle-end consumer also can enjoy convenient and joyful that the high-end science and technology in forward position brings, for popularizing and improving popular cultural life and opened up a platform.
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.
