[embodiment]
As shown in Figure 1, be the structural representation of touch-screen.Touch-screen comprises two layers of substrate 1,3 and is located at touch sensitive layer 2 between the two layers of substrate 1,3.The outside of substrate 1,3 can also increase protective seam etc.2 of touch sensitive layer are connected to the touch signal treatment circuit by signal wire.Normally a kind of structure of transparent conductive layer of touch sensitive layer 2.
As shown in Figure 2, be a kind of floor map of traditional structure of transparent conductive layer.This structure of transparent conductive layer comprises a plurality of first direction electrodes 110 and a plurality of second direction electrode 120, and wherein the bearing of trend of first direction electrode 110 and second direction electrode 120 is mutually orthogonal.First direction electrode 110 comprises a plurality of first direction conductive units 112 of arranging along first direction, and per two adjacent first direction conductive units 112 are connected by one section conductor wire 130 on first direction.Second direction electrode 120 comprises the second direction conductive unit 122 at a plurality of intervals, and per two adjacent second direction conductive units 122 are cut off by conductor wire 130 on second direction.Shown in Figure 2 is a kind of traditional connected mode, promptly adopts a conducting bridge 140 that second direction conductive unit 122 is coupled together.
Fig. 3 is the partial enlarged drawing of A part among Fig. 2.Wherein the shape of first conductive unit 112 and second conductive unit 122 can as prismatic, hexagon or other suitable shapes, be decided as required for multiple.
Fig. 4 is the partial structurtes synoptic diagram of the structure of transparent conductive layer of an embodiment in the conducting bridge part.With respect to the single bridge construction among Fig. 3, the structure of transparent conductive layer of present embodiment adopts two conducting bridges 240 to connect second direction conductive unit 222.Conducting bridge 240 comprises and is set up in the insulation course 242 between adjacent two second direction conductive units 222 and is located at metal bridge 244 on the insulation course 242 that metal bridge 244 electrically connects two adjacent second direction conductive units 222.Among other embodiment, metal bridge 244 also can be replaced by other conductive material.
In the present embodiment, first direction conductive unit 212 and second direction conductive unit 222 are made by the tin indium oxide material, and the conductor wire 230 that connects adjacent first direction conductive unit 212 on first direction also adopts the tin indium oxide material to make.
As shown in Figure 4, in the present embodiment, the quantity of the conducting bridge 240 of structure of transparent conductive layer is two.Between two conducting bridges 240 parallel and each other at interval distance greater than the length of conductor wire 230.Among other embodiment, the quantity of conducting bridge also can be for more than three, and parallel and equidistant distribution between a plurality of conducting bridge.Certainly, can not be equally spaced between a plurality of conducting bridge yet.
At traditional single bridge construction easy problem that lost efficacy in manufacturing process, plural conducting bridge is set between the second direction conductive unit, can be between a plurality of conducting bridges simultaneously as conductor wire, also can be standby each other, thereby can reduce the probability that conducting bridge lost efficacy, improved the yield rate of touch-screen.Because metal bridge 244 is that to etch away other parts of justifying metal formed, can't reduce make efficiency and increase cost so keep more metal bridge.
Further, in the structure of transparent conductive layer of present embodiment, also connect between the adjacent first direction conductive unit 212 by metal wire sections 250.The transparency conducting layer that adopts the tin indium oxide material to make, in manufacture process, first direction electrode 210 and second direction conductive unit 222 at interval form simultaneously, general employing obtains the transparency conducting layer etching of monoblock, therefore first direction conductive unit 212 and the conductor wire 230 that connects two adjacent first direction conductive units 212 are one, all are tin indium oxide material layers.Owing to the line between two conductive units generally is narrower, and the resistivity of transparent conductive material is generally bigger, so the resistance of the conductor wire 230 of tin indium oxide material is bigger, can influence the response speed of touch-screen.Increase metal wire sections 250 and connect the first direction conductive unit, can reduce the resistance of junction, improve the response speed of touch-screen.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
