Abstract
The invention discloses an OGS touch screen and belongs to the field of touch screens. The OGS touch screen solves the problem that the thickness of an ink frame layer leads to low quality of an ITO film. The OGS touch screen comprises a metal frame layer, a glass substrate, a shadow elimination film and an ITO conductive layer, wherein the shadow elimination film and the ITO conductive layer are arranged on the same side of the glass substrate, and the metal frame layer is arranged on the other side, opposite to the shadow elimination film and the ITO conductive layer, of the glass substrate. The metal frame layer is arranged on the other side, opposite to the side where the shadow elimination film and the ITO conductive layer are located, of the glass substrate, so that when the shadow elimination film is deposited, the phenomenon that a step effect is formed due to the thickness of the metal frame layer and accordingly the shadow elimination film fractures can be avoided.
Description
Technical field
The present invention 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 during deposition ITO film.
Summary of the invention
The object that the present invention will reach is to provide a kind of OGS touch-screen, can prevent the fracture of ITO film during making, can use the temperature deposition ITO conductive film layer that surpasses 230 ℃ simultaneously.
In order to achieve the above object, the present invention 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 on glass substrate the another side with respect to the shadow film that disappears, ITO conductive layer.
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 OGS touch-screen is arranged in order according to the order of 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, 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 on the first frame silk-screen layer the another side with respect to protective seam.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 is located on metal edge frame layer on top layer.
Further, described top layer is alundum (Al2O3) layer.
Adopt after technique scheme, tool of the present invention has the following advantages:
Metal edge frame layer is located on glass substrate the another side with respect to the shadow film that disappears, ITO conductive layer place one side, the step effect fracture that can avoid ITO film to form because of ink frame layer thickness during deposition ITO film.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the explosive view of each layer in an embodiment of the present invention.
Embodiment
Attachedly Figure 1 shows that a kind of embodiment of the present invention.
A kind of OGS touch-screen, comprise metal edge frame layer 2, glass substrate 3, niobium pentaoxide layer 4, ITO conductive layer 6, top layer 1, silicon dioxide layer 5, OC insulation course 7, metallic diaphragm 8, protective seam 9, the first frame silk-screen layer 10, the second frame silk-screen layer 11, niobium pentaoxide layer 4, silicon dioxide layer 5 forms the shadow film that disappears jointly, shadow film disappears, ITO conductive layer 6 is located at the same face on glass substrate 3, metal edge frame layer 2 is located on glass substrate 3 with respect to the shadow film that disappears, the another side of ITO conductive layer 6, each layer of OGS touch-screen is according to top layer 1, metal edge frame layer 2, glass substrate 3, niobium pentaoxide layer 4, silicon dioxide layer 5, ITO conductive layer 6, OC insulation course 7, metallic diaphragm 8, protective seam 9, the first frame silk-screen layer 10, the order of the second frame silk-screen layer 11 is arranged in order, adjacent two layers fits tightly, twice frame silk-screen after-vision effect is better.
Top layer is alundum (Al2O3), i.e. sapphire layer, and hardness is high, and scratch resistance ability is strong, uses hard material in order to protect metal edge frame.Protective seam adopts silicon dioxide.
The manufacture craft of above-mentioned OGS touch-screen, comprise the steps, in the one side of glass substrate, use temperature (also can adopt other values in 280 ℃, 320 ℃ or 280 ℃-320 ℃) the reactive sputter-deposition metallic compound TiCN (or TiN) of 300 ℃ and use etch process to make to form metal edge frame layer; On metal edge frame layer, cover alundum (Al2O3) as top layer; At the another side of glass substrate, use temperature (also can adopt other values in 215 ℃, 225 ℃ or 215 ℃-225 ℃) deposition one deck niobium pentaoxide of 210 ℃; On niobium pentaoxide, cover layer of silicon dioxide and niobium pentaoxide and jointly form the shadow film that disappears; Sputter tin indium oxide use the annealing temperature of 350 ℃ (also can adopt other values in 340 ℃, 360 ℃ or 340 ℃-360 ℃) process to form ITO conducting film, etched circuit on ITO conducting film on the shadow film that disappears; On ITO conducting film, cover the insulation of OC insulation course; On OC insulating film layer, use temperature (also can adopt other values in 215 ℃, 225 ℃ or 215 ℃-225 ℃) the deposition layer of metal rete of 210 ℃, etching gap bridge and circuit on metallic diaphragm; On metallic diaphragm, cover layer of silicon dioxide as protective seam; Carry out twice frame silk-screen and make OGS touch sensor; The one side of using OCA optical cement that display screen is fitted in to OGS touch sensor band matcoveredn is made OGS touch-screen.
Metal edge frame layer is located on glass substrate the another side with respect to the shadow film that disappears, ITO conductive layer place one side, the step effect fracture that can avoid ITO film to form because of ink frame layer thickness during deposition ITO film.
