Abstract
The utility model discloses a kind of capacitive touch screen, the touch-screen is followed successively by from top to bottom：Substrate, ink layer, insulating barrier, transparency conducting layer；The insulating layer pattern is three frame shapes, in touch-screen bottom without sealing, and sets 3/4 circular hollow slots in Kuang Xing corners.Capacitive touch screen of the present utility model is the circular hollow slots of corner's setting 3/4 in insulating layer pattern, and insulating barrier edge-smoothing transition, eliminate the vertical height drop produced between transparency conducting layer and substrate, compared with prior art, because insulating barrier corner pattern is away from visible area, and seamlessly transit and reduce vertical drop, the bubble produced when greatly reducing transparency conducting layer with baseplate-laminating piles up insulating barrier turning phenomenon, improve touch-screen production yield, cost is reduced, the sense organ of user is not influenceed and is used.
Description
Technical field
The utility model belongs to touch screen technology field, more particularly to a kind of capacitive touch screen.
Background technology
With continuing to develop for science and technology, touch-screen is used as a kind of simple, easily man-machine interaction mode, extensive use
In the every field of our daily lifes, such as mobile phone, media player, navigation system, digital camera, photo frame, PDA, game
Equipment, display, electrical equipment control, Medical Devices etc..Touch technology opens the new model of the interpersonal interactive operation of mobile terminal, low
Cost, high-quality have turned into touch-screen industry inevitable development trend.
At present, when capacitive touch screen is made, frame ink is typically all first covered in the substrate of touch-screen
On, then the Sensor with insulating barrier is fitted with substrate, because elder generation covers frame ink on substrate, while insulating barrier
There is certain thickness, make the drop for having on a height between Sensor and substrate, so when attaching process is carried out, easily
Appear in insulating pattern corner and the accumulation of bubble occur, cause the yields of touch-screen low, so as to have impact on production cost.
The content of the invention
The utility model devises a kind of capacitive touch screen to overcome the deficiencies in the prior art, to overcome during laminating
The bubble for appearing in insulating pattern corner piles up situation, improves product yield, reduces production cost.
To achieve these goals, the utility model is adopted the following technical scheme that：
A kind of capacitive touch screen, the touch-screen is followed successively by from top to bottom：Substrate, ink layer, insulating barrier, electrically conducting transparent
Layer；
The insulating layer pattern is three frame shapes, and sets 3/4 circular hollow slots in Kuang Xing corners.
The substrate is glass baseplate or PET base material.
The ink layer is formed in the bezel locations on substrate and outside touch screen window.
The ink layer is shading non-conductive ink.
The ink layer is arranged with OCA glue, and substrate can be made to be fitted with transparency conducting layer.
The insulating layer pattern is three frame shapes, and in touch-screen bottom without sealing, and it is circular to set 3/4 in Kuang Xing corners
Hollow slots, make the insulating pattern of corner away from touch-screen visible area.
The insulating barrier edge-smoothing transition, eliminates the vertical height drop produced between transparency conducting layer and substrate.
The insulating barrier is SiO2 layers, and its thickness is 8 ~ 12um.
The transparency conducting layer is covered on the insulating layer, and the transparency conducting layer in touch screen window region is formed and is used for
The circuit pattern of the touch-screen contact position is detected, the transparency conducting layer in touch-screen frame region is formed and circuit diagram
The conducting wire of case connection.
Understand that capacitive touch screen of the present utility model is the corner in insulating layer pattern via above-mentioned technical scheme
3/4 circular hollow slots, and insulating barrier edge-smoothing transition are set, the vertical height produced between transparency conducting layer and substrate is eliminated
Drop, compared with prior art, because insulating barrier corner pattern is away from visible area, and seamlessly transits and reduces vertical height
Difference, the bubble produced when greatly reducing transparency conducting layer with baseplate-laminating piles up insulating barrier turning phenomenon, improves touch-screen
Production yield, reduces cost, the sense organ of user is not influenceed and is used.
