Description
Technical field
The utility model relates to touch-screen field, particularly a kind of OGS touch-screen.
Background technology
The frame technique that at present OGS capacitive touch screen generally adopts is serigraphy or BM photoresist (with ITO layer at the same face), can substantially meet the request for utilization of OGS touch-screen, but the homogeneity of frame is poor, thickness is thicker, follow-up manufacturing process is brought to difficulty, easily because the step effect that the thickness of ink frame layer forms causes rete fracture, not high from the yields of product when deposition ITO film.
Summary of the invention
The object that the utility model will reach is to provide a kind of OGS touch-screen, can prevent the fracture of ITO film when making, can use the temperature deposition ITO conductive film layer that exceedes 230 DEG C simultaneously.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of OGS touch-screen, it is characterized in that: comprise metal edge frame layer, glass substrate, the shadow film that disappears, ITO conductive layer, disappear shadow film, ITO conductive layer is located at the same face on glass substrate, and metal edge frame layer is located at the another side with respect to the shadow film that disappears, ITO conductive layer on glass substrate.
Further, the shadow film that disappears described in comprises niobium pentaoxide layer and silicon dioxide layer.
Further; described OGS touch-screen also comprises OC insulation course, metallic diaphragm, protective seam, the first frame silk-screen layer; each layer of the OGS touch-screen order according to metal edge frame layer, glass substrate, niobium pentaoxide layer, silicon dioxide layer, ITO conductive layer, OC insulation course, metallic diaphragm, protective seam, the first frame silk-screen layer is arranged in order, and adjacent two layers fits tightly.
Further, described OGS touch-screen also comprises the second frame silk-screen layer, and the second frame silk-screen layer is located at the another side with respect to protective seam on the first frame silk-screen layer.Twice frame silk-screen after-vision effect is better.
Further, described OGS touch-screen also comprises top layer, and the another side with respect to glass substrate on metal edge frame layer is located on top layer.
Further, described top layer is alundum (Al2O3) layer.
Adopt after technique scheme, the utlity model has following advantage:
Metal edge frame layer is located at the another side with respect to the shadow film that disappears, ITO conductive layer place one side on glass substrate, the step effect fracture that can avoid ITO film to form because of ink frame layer thickness when deposition ITO film.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail:
