Embodiment
For reaching employed technological means of purpose and effect, and following graphic cited embodiment only is an aid illustration hereinafter with reference to the graphic the present invention of description who encloses, and in order to understanding, but that technological means of the present invention is not limited to is cited graphic.
See also shown in Figure 1ly, be the schematic diagram of preferred embodiment of the present invention.This touch panel 20 shown in the figure is a four-wire resistance type, the inside of this touch panel 20 is laid with four Communication signal wires 10 and a ground wire 14, this ground wire 14 is around the outermost that is arranged at these four Communication signal wires 10, and the two-end-point of this ground wire 14 is positioned at the end points outermost of these four Communication signal wires 10, is being formed with plural number between the two adjacent Communication signal wires 10 and between adjacent Communication signal wire 10 and the ground wire 14 to point discharge structure 12 respectively.
This point discharge structure 12 forms in Communication signal wire 10 both sides in pairs, these point discharge structure 12 monolateral ground wire 14 1 sides that form in, and in the position that is formed with point discharge structure 12, its each bar Communication signal wire 10 and ground wire 14 all can be formed with point discharge structure 12 at same horizontal level, and each is to tool one clearance D between the point discharge structure 12, the distance of each clearance D is identical, the touch panel 20 that the present invention used can be condenser type or resistance-type, this resistance-type panel can be four-wire resistance type and also can be five wire resistance types, and does not exceed with of the present invention.
See also shown in Figure 2ly again, be the schematic diagram of point discharge structure first form of the present invention.Shown in the figure, one Communication signal wire, 10 bilateral symmetry are formed with some point discharge structures 12, and this point discharge structure 12 is a standing shape, and form in relatively between two Communication signal wires 10, this point discharge structure 12 is mainly the triangular structure of identical size, or can be acicular texture etc.Also can be formed with the point discharge structure between this Communication signal wire 10 and this ground wire 14, some a plurality of point discharge structures 12 of this each bar Communication signal wire 10 and this ground wire 14 can form on the same horizontal level.In other words, having on the position that this point discharge structure 12 is set, Communication signal wire 10 on its same horizontal level and ground wire 14 all are formed with this point discharge structure 12, and at ground wire 14 1 ends, this point discharge structure 12 is a monolateral side that forms in this ground wire 14 towards Communication signal wire 10, two wherein relative Communication signal wires are one group, each 12 on group point discharge structure has clearance D, and the distance of each clearance D is identical, this clearance D can make static be passed to opposite side point discharge structure 12 by a side point discharge structure 12, and make static be passed to ground wire 14 laterally by inside, make it be able to guide out from ground wire 14.
See also shown in Figure 3ly again, be the schematic diagram of point discharge structure second form of the present invention.Present embodiment is that wiring that Communication signal wire 10 is done right angle bending is when being provided with, arbitrary limit, angle of cut place at these Communication signal wire 10 right angles is formed with a point discharge structure 12, in other words, promptly be the point discharge structure 12 that is shaped on angle of cut end 15 arbitrary limits of the vertical edges in the right angle outside and horizontal sides.
