Abstract
The invention provides a capacitive touch screen with a circuit on a panel. The touch screen is composed of a top ITO GLASS (indium tin oxide glass), an optical clear adhesive and a bottom SENSOR, and the top ITO GLASS is connected with the bottom SENSOR through an FPC (flexible printed circuit) and glued through the optical clear adhesive. The capacitive touch screen is simple in process structure, low in production cost and high in sensitivity.
Description
Technical field
The present invention relates to a kind of touch-screen, particularly a kind of capacitance touch screen of panel band circuit.
Background technology
All be hot pressing (the SENSOR material can be ITO FILM or ITO GLASS) on SENSOR at every projection-type capacitive touch screen FPC on the market at present.Structure is made of top panel, optical cement, bottom SENSOR and FPC, basic functional principle is: 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 touch-screen that traditional handicraft makes, its defective is: complex process, need high-end devices and laminated material, affect production efficiency and production capacity, the product price of producing 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 capacitance touch screen of panel band circuit, described touch-screen is made of top ITO GLASS, optical cement, bottom SENSOR, described top ITO GLASS is connected with bottom SENSOR by FPC, and described top ITO GLASS and bottom SENSOR are by the optical cement gluing.
As the preferred technical solution of the present invention, described top ITO GLASS is the panel of touch-screen, is the upper circuit part of touch-screen, by silver slurry printing and ITO etching in conjunction with wiring.
As the preferred technical solution of the present invention, described bottom SENSOR is that PET or GLASS are the conducting wire plate of base material, is used for wiring topology, is the lower circuit part of touch-screen.
The contrast prior art, the beneficial effect that the present invention brings is: process structure is simple, and production cost is low, and is highly sensitive.

Fig. 2 is Fig. 1 right view
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 capacitance touch screen of panel band circuit, described touch-screen is made of top ITO GLASS 1, optical cement 2, bottom SENSOR 3, described top ITO GLASS 1 is connected with bottom SENSOR 3 by FPC 4, and described top ITO GLASS 1 and bottom SENSOR 3 are by optical cement 2 gluings.Described top ITO GLASS 1 is the panel of touch-screen, is the upper circuit part of touch-screen, by silver slurry printing and ITO etching in conjunction with wiring.Described bottom SENSOR 3 is that PET or GLASS are the conducting wire plate of base material, is used for wiring topology, is the lower circuit part of touch-screen.
Comprehensive above-mentioned seeing, because adopt panel heat pressing process and GF structure, the holistic cost of projection-type capacitive touch screen is compared other structures and has been descended significantly, and obtains 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.
