Abstract
The utility model discloses a novel touch screen, comprising a PU printing ink layer, an ITO electro-conductive glass layer, an optic glue layer and a transparent conductive thin layer. The PU printing ink layer is sprayed on an upper surface of the ITO electro-conductive glass layer; a lower surface of the ITO electro-conductive glass layer is in fixed connection with the transparent conductive thin layer through the optic glue layer. The novel touch screen has reduced forming layers; the costs of a whole touch screen are minimized; manufacture processes and difficulty are substantially reduced; and meanwhile reaction is more sensitive.
Description
Technical field
The utility model relates to the liquid crystal indicator technical field, relates in particular a kind of capacitive touch screen.
Background technology
Touch-screen is called again " touch screen ", " contact panel ", it is a kind of induction type liquid crystal indicator that receives the input signals such as contact, when having contacted the graphic button on the screen, haptic feedback system on the screen can drive various hookup mechanisms according to the formula of in advance programming, can be in order to the push button panel of dessert machine tool formula, and produce lively visual and sound effects by liquid crystal display picture.Touch-screen is as a kind of up-to-date computer input apparatus, and it is simple, convenient, the most natural present a kind of man-machine interaction mode.Touch-screen is divided into again resistance-type and condenser type, the touch-screen of resistance-type is with low cost, and range of application is more extensive, and for example number of patent application is that the Chinese invention patent of CN201110444549.6 discloses a kind of capacitance touch screen, such touch-screen, the used number of plies is too much, so that the cost of whole touch-screen promotes greatly, is unfavorable for selling, weakened the competitive power in its market, in addition, go back so that the reaction velocity of touch-screen reduces greatly, sensitive not.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art part, and a kind of novel touch screen is provided.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: novel touch screen, consisted of by PU ink lay, ITO conductive glass layer, optics glue-line and transparent conductive film layer, described PU ink lay is sprayed on the upper surface of described ITO conductive glass layer, and the lower surface of described ITO conductive glass layer is fixedly connected with described transparent conductive film layer by the optics glue-line.
For the cost of manufacture that reduces touch-screen, improve its sensitivity, the touch-screen that is made of PU ink lay, ITO conductive glass layer, optics glue-line and transparent conductive film layer that order arranges, best results are found in the test of the applicant by repeatedly.
As preferably, the thickness of described ITO electropane is 0.4-1.1mm.
As preferably, described PU ink film thickness is 15-20 μ m.
As preferably, described optical cement layer thickness is 50-150 μ m.
As preferably, described transparent conductive film layer thickness is 13-20 μ m.
As preferably, described PU ink film thickness is 18 μ m.
As preferably, the thickness of described ITO electropane is 0.4mm.
As preferably, described optical cement layer thickness is 100 μ m.
As preferably, described transparent conductive film layer thickness is 0.13mm.
The utility model beneficial effect is: the number of plies reduces, so that the cost of whole touch-screen significantly reduces, the technique of its making, difficulty also significantly reduce, simultaneously, so that reaction is more sensitive.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Among the figure:
The 1-PU ink lay;
The 2-ITO conductive glass layer;
