Abstract
The utility model discloses a resistance type touch screen, which is in a four-layer structure including a PET protective layer, an upper conducting layer, a lower conducting layer and a tempered glass layer. The upper surface of the PET protective layer is hardened, and a non-window area on the lower surface of the PET protective layer is provided with a color film decorative frame which is prepared by physical vacuum plating; and the tempered glass is common soda-lime glass through strengthening treatment. By adopting the structure, the touch screen has more abundant colors, attractive appearance and stronger integral compression and impact resistance.
Description
[technical field]
The utility model is mainly used in the touch-screen of various electronic equipments, especially handset touch panel.
[background technology]
Touch-screen is a kind of remarkable input equipment that improves man machine operation interface, have intuitively, simply, advantage efficiently.Touch-screen has obtained to use widely in many electronic products, such as mobile phone, PDA, multimedia, public information inquiry system etc.In the past, various types of touch-screens constantly occur, and comprise resistance-type, condenser type, infrared and surface acoustic wave type touch-screen.Wherein, resistive touch screen is to use the most general touch screen technology in the market.
Resistive touch screen is to utilize pressure sensitive to control.When finger or felt pen click touch screen, upper and lower two conductive layers produce contact in this position, the resistance of system is changed, cause producing signal respectively on X-axis and the Y-axis both direction, controller according to the calculated signals of measuring go out contact point position coordinates (X, Y), final, main frame explain the position coordinates that controller provides (X, Y) and carry out events corresponding.At present, the upper and lower conductive layer of resistive touch screen exists film-film, film-glass or glass-glass structure.In order to protect the plain conductor at conductive layer and covering conductive layer edge, need on last conductive layer, increase protective seam; In order to strengthen the rigidity of touch-screen, the abundant transparent material of one deck need be increased, under lower conductiving layer such as poly-carbon resin, acrylic board, glass etc.
On above-mentioned protective seam, there are form and non-window area.Past in the non-window area of protective seam, is to adopt screen printing mode to cover the printing ink of particular color as Decorative frame.These printing ink mainly are made up of organic binder bond and pigment, usually occur fading, variable color, many-sided problem such as picture and text are unintelligible, adhesion is not good enough.
In above-mentioned touch-screen, although increased abundant transparent material under lower conductiving layer, their mechanicalness and stability are all not ideal enough, and influence the transmitance of touch-screen.
[utility model content]
The utility model has been done improvement at the deficiencies in the prior art, makes the color of touch-screen abundant, outward appearance is beautiful, environmental stability is high, resistance to compression and impact strength excellence.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of resistive touch screen has four-layer structure, by on fall down to be followed successively by PET protective seam (1), go up conductive layer (2), lower conductiving layer (3) and tempered glass layer (4).
Wherein, described PET protective seam (1) is divided into viewfinder area (5) and non-viewfinder area (6), and material is PET, and upper surface has prepared the film modified frame of color through cure process at non-viewfinder area (6).PET protective seam, material are the PET of upper surface through cure process, have the anti-scratch function.The lower surface of protective seam adopts physical vacuum coating technology, prepares color film Decorative frame in its non-window area.This color film is made up of metal film or the staggered multilayer inorganic thin film of high and low refractive index.Different colors can be by regulating the material and the thickness of film, owing to interference effect realizes.
Adopt tempered glass under lower conductiving layer, tempered glass is common reinforcement soda-lime glass, and its thickness is 0.3-3mm.
After the utility model has adopted technique scheme, compared with prior art, have following beneficial effect: the color film preparation of protective seam is to adopt physical vacuum coating technology, and this has improved the adhesion of film and protective seam; The color film is made up of metal film or multilayer inorganic thin film, organic relatively printing ink, and its environmental stability is very high; By material and the thickness of regulating each layer inorganic thin film, can make protective seam manifest random color, therefore, the color of touch-screen is abundanter, and outward appearance is beautiful; Under lower conductiving layer, adopt tempered glass, not only improved the rigidity and the transmitance of touch-screen, and the resistance to compression of touch-screen and impact strength raising, satisfy user demand.
