Background technology
Capacitive touch screen is as a kind of new human-computer interaction device, and because of its input mode simply and easily, be widely used in the fields such as mobile phone, vehicle-carrying display screen, public information inquiry system, market outlook are very wide.
OGS bridging touch-screen is because product thickness is thin, cost is low, touch-control sensitivity is good, become the main product of capacitive touch screen in the market, but along with touch-screen uses the continuous expansion in field, the performance of OGS bridging touch-screen is had higher requirement.
Bridging touch-screen is in the market all adopt structure of singly putting up a bridge, and namely only there is a bridging structure between different passage, touch-screen has hundreds of bridging points, and therefore, as long as one of them is put up a bridge, bad point appears in point, and monoblock touch-screen will lose value.Therefore how improving the stability of point of putting up a bridge, thus improve the stability of producing product in yield and user's use procedure, is bridging touch-screen urgent problem.
Utility model content
The purpose of this utility model is to overcome defect of the prior art, and provide a kind of two bridging structures of OGS capacitive touch screen, adopt touch-screen prepared by this structure, touch-control is sensitive, good stability, and yield is high.
For achieving the above object, the utility model adopts following design proposal:
Two bridging structures for OGS capacitive touch screen, it comprises: glass substrate; If multiple cross one another X electrode on the glass substrate and Y electrode; wherein each X electrode comprises two electrode modules; two electrode modules of described X electrode form one and drive passage; each Y electrode comprises an electrode module; an electrode module of described Y electrode forms an induction channels; described Y electrode connects continuously; X electrode disconnects at the infall with Y electrode; by bridging anatomical connectivity, described bridging structure sequentially comprises insulation course, bridging conductive film layer and protection ink layer from top to bottom.
Preferably, described X electrode or Y electrode are at least one in ito thin film layer, graphene film layer.
Preferably, described bridging conductive film layer is at least one in Al-Doped ZnO, boron-doping zinc paste.
Preferably, the length of described insulation course is 50-400um, and width is 50-300um, and thickness is 5-25um.
Preferably, described bridging conductive film layer length is 70-500um, and width is 10-200um, and thickness is 1-15um.
Preferably, described protection ink layer length is 80-600um, and width is 20-250um, and thickness is 5-20um.
Compared with prior art, the utility model adopts two bridging structure, and after one group of bridging structure is ineffective, another group bridging structure of same passage still can work, thus improves the product stability produced in yield and use procedure.Meanwhile, bridging point more single bridging structure of two bridging structure is many one times, and therefore touch-control sensitivity is better, user can be made to obtain better sense of touch and enjoy.
