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 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 touch screen performance.
The utility model content
The technical problems to be solved in the utility model is, a kind of capacitive touch screen wiring is provided, and solves the high defective of line resistance that existing capacitive touch screen wiring exists aberration, the local broken string of lead and 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, 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 this dielectric film is positioned on the substrate surface at the contiguous place of this nesa coating, and described metal bridging rete connects the second group of lead nesa coating that is provided with at interval in the nesa coating both sides of described first group of lead across described dielectric film to be made it to become second group of continuous lead and cover substrate surface between this connected second group of lead nesa coating and this dielectric film.
In capacitive touch screen wiring of the present utility model, described metal bridging rete is one or more layers of metal level or metal alloy layer.
In capacitive touch screen wiring of the present utility model, described dielectric film is shaped as rectangle, square or one of oval.

Implement capacitive touch screen wiring of the present utility model, compared with the prior art, its beneficial effect is:
1. the transparent conductive film layer of two groups of leads can be made simultaneously, has avoided making the aberration that causes respectively, has improved the product quality of touch-screen;
2. metal bridging rete is thicker, is not prone to the broken string phenomenon, has improved the continuity of second group of lead;
3. the line resistance of metal bridging rete has reduced the line resistance of second group of lead much smaller than the line resistance of transparent lead rete, has improved the performance of touch-screen;
4. contiguous second group of lead nesa coating one lateral edges of dielectric film and do not contact second group of lead nesa coating, perk can not appear in the dielectric film edge, so metal bridging rete can not break at the edge of dielectric film, has improved yield of products.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural plan figure of the node of a kind of embodiment of the utility model capacitive touch screen wiring.
Fig. 2 is an A-A sectional view among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, capacitive touch screen wiring of the present utility model comprises nesa coating and the dielectric film that is arranged on the glass substrate 1 respectively two groups of leads arranging along X, Y both direction.The nesa coating 4 of first group of lead is provided with continuously, the nesa coating 2 of second group of lead is the space segmentation setting with the nesa coating 4 of first group of lead, dielectric film 3 covers the nesa coating 4 of first group of lead of two groups of lead infalls, the edge of dielectric film 3 is positioned on the surface of these nesa coating 4 contiguous substrates of locating 1, metal bridging rete 5 is set, this metal bridging rete 5 connects second group of lead nesa coating 2 that nesa coating 4 both sides that are positioned at first group of lead are provided with at interval across dielectric film 3 makes it to become second group of continuous lead, and this metal bridging rete 5 covers the surface of the substrate 1 between these connected second group of lead nesa coatings 2 and this dielectric film 3 simultaneously.So promptly finished two groups of leads mutually insulated, complete, because dielectric film 3 do not contact second group of lead nesa coating 2, the edge of dielectric film 3 can perk, so metal bridging rete 5 can not break in the edge of dielectric film 3.The end of metal bridging rete 5 intactly is connected with second group of lead nesa coating 2, for the quality of connection of raising and assurance metal bridging rete 5 and second group of lead nesa coating 2 has been created condition.
Metal bridging rete can be adopted as the metal level or the metal alloy layer of one deck, two-layer, three layers or multilayer.Its thickness is much larger than the thickness of transparent conductive film layer, therefore, adopt metal bridging rete to carry out wire jumper, be not easy to produce the broken string phenomenon, and the line resistance of metallic diaphragm is much smaller than the line resistance of transparent conductive film layer, so bridging jumper wire construction of the present utility model has reduced the line resistance of second group of lead, thereby has improved the performance of touch-screen.
