The area of wiring region B.
Referring to Fig. 8, another embodiment construction of touch panel of the present invention is wherein painted, with Fig. 7 corresponding embodiments
Difference lies in wherein first transmission line 51 and second transmission line 52 are respectively positioned on wiring region B, first transmission line 51 and second transmission line
52, which can be used the relatively low metal material of impedance, forms.In this way, the transmission line for connecting the first touch control electrode 41 is respectively arranged at
The front and back of transparent substrate 30 reduces the quantity of transmission line arranged side by side, can reduce the area of wiring region B.Into one
Step, the upright projection of first transmission line 51 and second transmission line 52 on transparent substrate 30 at least partly overlaps, and passes through increase
Overlapping region area further reduces the area of wiring region B.
In addition, in the corresponding embodiments of Fig. 8, first transmission line 51 and second transmission line 52 are vertical on transparent substrate 30
Projection can not overlap, only its respectively place wiring region at least partly overlap.Referring to Fig. 9, Fig. 9 paints the first transmission
Another embodiment of 52 place wiring region of line 51 and second transmission line, including the first wiring region B1 and one second wiring region B2, the
One transmission line 51 is located at the first wiring region B1, and second transmission line 52 is then to be located at the second wiring region B2, wherein first transmission line 51
Substantially not fully being overlapped with upright projection of the second transmission line 52 on transparent substrate 30 (can adopt and staggeredly overlap or interlock
But misaligned mode is arranged), and 52 corresponding first wiring region B1 and second of first transmission line 51 and second transmission line
Upright projections of the wiring region B2 on transparent substrate 30 at least partly overlaps, and is so reduced by increasing overlapping region area
The area of wiring region B.
It is electrical respectively with first transmission line 51 and second transmission line 52 in the previous embodiment of touch panel of the present invention
Different the first touch control electrode 41 of plural item for being connected to same extending direction carrys out the reality for example, as depicted in Fig. 2 to Fig. 8
Apply example construction and all belong to this embodiment, plural number first transmission line 51 and second transmission line 52 therein be electrically connected in
The different first direction electrode 41 of plural item.Only embodiments of the present invention are not limited thereto, and in other words, can regard touch surface
The touch control electrode 40 of plate, the outgoing line position of first direction electrode 41 and second direction electrode 42 or mode, reasonable disposition are electric respectively
Property is connected to the transmission line of first direction electrode 41 and second direction electrode 42 to reduce the area of wiring region.As shown in Figure 10
It is the configuration mode of alternatively possible transmission line, difference lies in second transmission line 52 is set to Fig. 8 corresponding embodiments
The front 31 of bright substrate 30, and it is electrically connected at second direction electrode 42,52 part of second transmission line is set under the A of Touch Zone
Side, further around cross Touch Zone A left side, and be similarly positioned in the first transmission line 51 of Touch Zone A left sides in transparent substrate 30
On upright projection at least partly overlap, reduced by increasing first transmission line 51 and 52 overlapping region area of second transmission line
The area of wiring region.
In addition, in the aforementioned embodiment, first direction electrode 41 only connects transmission line with second direction electrode 42 with one end,
Namely single-ended outlet, but in other embodiments, each first direction electrode 41 and second direction electrode 42 can its two
End is separately connected transmission line, to reduce signal decaying, improves touch-control sensitivity.When by the way of this bilateral outlet, pass
The set-up mode of defeated line can refer to present invention, be flexibly set to transparent substrate 30 the back side 32 or front 31 and the back of the body
Face 32, and overlapped at least part of second transmission line 52 with first transmission line 51 or first transmission line 51 using touch control electrode 40
Mode reduce the area of wiring region.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent substitution, improvement and etc. done should be included within the scope of protection of the invention god.
