Background technology
The wiring of touch-screen comprises two groups of leads that intersect in length and breadth along directions X and Y direction, and there is following defective in existing touch screen wiring structure:
1, two groups of leads of directions X and Y direction are space crossed, in manufacturing process, need to make earlier one group of lead conducting film of bottom, make dielectric film then, make the one group of lead conducting film in upper strata again.Because the nesa coating of two groups of leads must be made respectively, can cause the color distortion of two-layer conducting film, reduce the product quality of touch-screen;
2, because the lead conducting membrane material adopts transparent material, and rete is thinner, the phenomenon that breaks appears in bridging rete above the crossing crunode place of two groups of leads is positioned at easily, causes the local broken string of lead;
3, the line resistance of lead conducting film is higher, reduces the sensitive performance of touch-screen.
The utility model content
The technical problems to be solved in the utility model is, a kind of capacitive touch screen wiring structure is provided, and solves the high defective of line resistance that existing capacitive touch screen wiring structure exists aberration, the local broken string of lead, lead conducting film.
The technical scheme that its technical matters that solves the utility model adopts is: construct a kind of capacitive touch screen wiring structure, comprise and be arranged in glass substrate upper edge X, the nesa coating and the dielectric film of two groups of leads that the Y direction is arranged, it is characterized in that, also comprise metal bridging rete, the nesa coating of first group of lead is provided with continuously in described two groups of leads, the nesa coating of second group of lead is the space segmentation setting with the nesa coating of described first group of lead, described dielectric film covers the nesa coating of described first group of lead of described two groups of lead infalls, the edge of the nesa coating of second group of lead and the substrate surface of described infall, second group of lead nesa coating that the nesa coating both sides that described metal bridging rete is positioned at described first group of lead across described dielectric film connection are provided with at interval makes it to become second group of continuous lead.
In capacitive touch screen wiring structure of the present utility model, described metal bridging rete is one or more layers of metal level or metal alloy layer.
