Abstract
The utility model discloses a touch screen with low reflectivity, which comprises a touch screen body. A first phase coating is adhered onto the upper surface of the touch screen body, a polarizer is adhered onto the upper surface of the first phase coating, a second phase coating is adhered onto the lower surface of the touch screen body, and an anti-reflection film is adhered onto the lower surface of the second phase coating. The touch screen with low reflectivity leads light source of a liquid crystal screen on an electronic product to be unified into light capable of passing one certain direction of the polarizer, converts partial reflected light of external light entering inside of the touch screen into light incapable of passing a polarizer direction, and accordingly leads the electronic product equipped with the touch screen to be fundamentally unaffected by light reflection when in outdoor use, thereby leading image displayed by a display screen of the electronic device to be clearly seen.

Background technology
The tradition four-wire resistance type touch screen is made up of ito thin film and ito glass, and ITO is a kind of weakly conducting medium (having another name called tin indium oxide).Two conductive layer combination of ito thin film and ito glass form the workplace of touch-screen, the workplace that is touch-screen is made up of two-layer ITO conductive layer, two-layer ITO conductive layer is middle by the isolating points that is evenly distributed at interval, produce flexural deformation when press in the force outside the upper strata ito thin film is subjected to and contact with the lower floor ito glass and make ITO conductive layer conducting up and down, just can realize the function of location recognition by the magnitude of voltage of ITO layer firing point position about the measurement.The ITO conductive layer surface obtains a voltage field that is evenly distributed in order to make up and down, and every layer of ITO layer is printed on pair of parallel silver line, every corresponding electrode of silver-colored line, and totally four electrodes are drawn by the FPC connection.
If the electrode of two silver-colored lines on the definition ito thin film is Y+ and Y-, then the electrode of two silver-colored lines on the ito glass is exactly X+ and X-, when on the electrode pair of Y direction, applying a voltage of determining, the directions X electrode pair does not apply voltage, the magnitude of voltage of Y direction voltage field is monitored out by the X electrode tip during click, thereby reaches the position of identifying the Y direction, in like manner applies voltage is identified directions X by the Y electrode position at the directions X electrode pair, obtain the X of contact at last, the Y coordinate figure.
The tradition four-wire resistance type touch screen is by common PET base material I TO film and common ito glass is two-layer combines, it on the structure double-layer structure, between two-layer by isolating points at interval, ambient light can form a certain proportion of reflected light at every layer, reflected light can disturb the vision of human eye, the strong more then reflected light of ambient light is also strong more, and is just big more to the interference of vision.The electronic product that therefore traditional four-wire resistance type touch screen is used is difficult to see the image of electronic product itself when using out of doors.
The utility model content
The utility model embodiment technical matters to be solved is, a kind of touch-screen of antiradar reflectivity is provided, thereby also can see the image of electronic product itself when making the electronic product of touch-screen applications use out of doors easily.
In order to solve the problems of the technologies described above, the utility model embodiment provides a kind of antiradar reflectivity touch-screen, and it comprises the touch-screen main body, posts first membrane phase at the upper surface of described touch-screen main body, and described first membrane phase upper surface posts polaroid; Lower surface in described touch-screen main body posts second membrane phase.
Particularly, described touch-screen main body comprises conductive membrane layer and conductive glass layer, and described first membrane phase is attached to the upper surface of described conductive membrane layer; Described second membrane phase is attached to the lower surface of described conductive glass layer.
More specifically, described conductive membrane layer is the tin indium oxide conductive membrane layer, and described conductive glass layer is the indium tin oxide-coated glass layer.
Described polaroid is a linear polarizer plate, and polarizing angle is 135 degree or 45 degree; Thickness is 0.2mm.The phasic difference of the described first phasic difference film and second membrane phase is 1/4; Thickness is 0.05mm.Described second membrane phase lower surface posts anti-reflection film, and its thickness is in the scope of 0.1mm to 0.2mm.
Implement the utility model embodiment, has following beneficial effect: because the utility model has pasted polaroid and membrane phase at the upper surface of traditional touch-screen, lower surface has pasted membrane phase and anti-reflection film, making that the light source of electronic product LCD screen is unified into can be by the light of a certain specific direction of polaroid, and part enter that the reflected light of the external light in the touchscreen has been transformed into can not be by the light of polaroid direction; So just make the electronic product that has touch-screen not be subjected to the influence of light reflection when using out of doors substantially, also can see the image of electronic product itself easily.
Description of drawings
Fig. 1 is the sectional view of a kind of antiradar reflectivity touch-screen of the utility model embodiment.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment of the present utility model provides a kind of four-wire resistance type touch screen that external light is had antiradar reflectivity (reflectivity is less than 1%) effect.It has increased by four layers of optical material on the touch-screen basis of conventional film to glass structure, wherein two-layer optical material (polaroid and phasic difference film) is attached to the front of traditional structure touch-screen, and two-layer in addition optical material (phasic difference film and anti-reflection film) is attached to the back side of traditional structure touch-screen.
With reference to Fig. 1, a kind of antiradar reflectivity touch-screen of the present utility model, it comprises the touch-screen main body of being made up of ito thin film layer 11 and ito glass layer 12, wherein ITO is a kind of weakly conducting medium (having another name called tin indium oxide); Upper surface at described ito thin film layer 11 posts first membrane phase 2, and described first membrane phase upper surface posts polaroid 3; Lower surface at described ito glass layer 12 posts second membrane phase 4, and these second membrane phase 4 lower surface posts anti-reflection film 5.Between ito thin film layer 11 and ito glass layer 12, there is lead (FPC) 6 to draw.
Above-mentioned antiradar reflectivity touch-screen is used in combination with the LCD liquid crystal display, and the antiradar reflectivity touch-screen is placed on the top of LCD liquid crystal display, and the anti-reflection film 5 at the antiradar reflectivity touch-screen back side contacts with the LCD liquid crystal display.
