Embodiment
Below will be with reference to the graphic the present invention of description who encloses for reaching employed technological means of purpose and effect, and below graphic cited embodiment be merely aid illustration, 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 sketch map 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, and this resistance-type panel can be four-wire resistance type and also can be five wire resistance types, and does not exceed with according to the invention.
See also shown in Figure 2ly again, be the sketch map 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, and two wherein relative Communication signal wires are one group, and 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 makes static be passed to ground wire 14 laterally by inside, makes it be able to guide out from ground wire 14.
See also shown in Figure 3ly again, be the sketch map 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.
See also shown in Figure 4ly again, be the sketch map of flexible circuit board inner tip discharging structure.It shown in the figure flexible circuit board 30; Its inside has a plurality of Communication signal wires 10 and at least one side of the right and left outermost is formed with a ground wire 14; And plural number is to point discharge structure 12; It is formed separately on two adjacent Communication signal wires 10 and adjacent Communication signal wire 10 and ground wire 14, and each is to tool one clearance D between the point discharge structure 12.
See also again shown in Figure 5, Communication signal wire 10 and ground wire 14 Communication signal wire 10 and the ground wire 14 palpuses corresponding connection inner that this flexible circuit board 30 is inner with this touch panel (seeing also shown in Figure 1); In other words; Communication signal wire 10 on the pin end 31 of this flexible circuit board 30 and ground wire 14 its quantity and installation position must be to the Communication signal wire 10 on should the connectivity port (not shown) of touch panel and the quantity and the installation positions of ground wire 14; When so the pin end 31 of this flexible circuit board 30 is connected with the connectivity port of this touch panel; Static in the touch panel can be derived touch panel by above-mentioned connection, and it is minimum to make touch panel dropped to by the influence of static.
The pin end 31 of this flexible circuit board 30 and the wire connecting ends of this touch panel 21 electrically connect with conducting resinl, and another pin end 32 and the wire connecting ends mouth 41 of this liquid crystal panel 40 of this flexible circuit board 30 electrically connects.
But the above is merely embodiments of the invention, when can not with the scope implemented of qualification the present invention.The equalization of promptly doing according to claim of the present invention generally changes and modifies, and all should still belong in the scope that patent of the present invention contains.
