Further, if the segment signal line in the first signal wire 251 is the signal wire of odd-numbered line, remainder signal wire
For the even line signal line adjacent with odd-numbered line, if the quantity of the first signal wire 251 is equal with the quantity of secondary signal line 252,
And be located at the first area of contact panel with the position that the first signal wire 251 electrically connects with touch control electrode on contact panel 23, then
First signal wire 251 and secondary signal line 252 periphery cabling area 21 cabling distribution and the signal wire 251 of embodiment 2 first and
Cabling of the secondary signal line 252 in periphery cabling area 21 be specially:
First signal wire 251 is set with metal level 11 with layer, and is electrically connected with drive circuit 24, and the first signal wire 251 is logical
The first via 121 for crossing insulating barrier 12 electrically connects with the second touch control electrode 232 of transparent conductive film layer 13, wherein, the first signal
The region that line 251 electrically connects with the second touch control electrode 232 of transparent conductive film layer 13 is located at the second area 32 of contact panel.The
Binary signal line 252 is set with transparent conductive film layer 13 with layer, the first touch-control electricity of secondary signal line 252 and transparent conductive film layer 13
Pole 231 electrically connects, wherein, the region position that secondary signal line 252 electrically connects with the second touch control electrode 232 of transparent conductive film layer 13
In the first area 31 of contact panel, secondary signal line 252 is by the second via 122 of insulating barrier 12, with the electricity of drive circuit 24
Connection.And first the projection in periphery cabling area 21 in vertical direction of signal wire 251 and secondary signal line 252 at least partly
It is overlapping.
The embodiment of the present invention is to the signal wire in the first signal wire 251 and the corresponding periphery cabling area 21 of secondary signal line 252
Middle odd line signal line or even line signal line be not further to be limited.
Further, in embodiments of the present invention, no matter the corresponding periphery of the first signal wire 251 and secondary signal line 252 is walked
Odd line signal line or even line signal line in signal wire in line area 21, the first signal wire 251 exist with secondary signal line 252
Projection in the cabling area of periphery in vertical direction can at least partly overlap.
Based on same inventive concept, the embodiment of the present invention also provides a kind of touch control display apparatus, and touch control display apparatus includes
Contact panel in the embodiment of the present invention.
Further, the touch control display apparatus can be:Mobile phone, tablet personal computer, display, to compare this computer etc. any
Product or part with display function.
A kind of preparation method of contact panel provided in an embodiment of the present invention is illustrated in figure 8, this method includes:
Step 101, provide first substrate;
Step 102, the forming metal layer on surface in first substrate, patterned metal layer, form the first signal wire;
Step 103, insulating barrier is formed on the surface of metal level, patterned insulation layer, form the first mistake on the insulating layer
Hole and the second via,
Step 104, transparent conductive film layer is formed on the insulating layer, patterned transparent conductive film layer, form the first touch-control electricity
Pole, second touch control electrode and secondary signal line, wherein, the first signal wire is electrically connected with the first touch control electrode by the first via,
Secondary signal line electrically connects with second touch control electrode, and is arranged on the first signal wire and secondary signal of contact panel phase homonymy
Projection of the line in first substrate vertical direction is least partially overlapped.
