In addition, the end concentrated setting that the present embodiment can make the second wire 150 extend to shading region A2 extends to the side of the end of shading region A2 at the first wire 140, engage with a signal transmission circuit in order to the first wire 140 and the second wire 150, but the present invention is not limited thereto.In another embodiment, the end of the first wire 140 and the end of the second wire 150 can engage from different signal transmission circuits respectively.So, together with the first wire 140 and the second wire 150 can be adjacent at the end of shading region A2.
In addition, though first electrode 120 of above-described embodiment and the second electrode 130 all represent with tandem kenel, the present invention is not limited thereto.Figure 11 is the upper schematic diagram of a kind of contact panel of another embodiment of the present invention.Please refer to Figure 11, contact panel 300 is approximately identical to contact panel 100, and identical element represents with identical label, repeats no more in this.Main Differences is, at least one of them the shape of each first electrode 120A of the present embodiment and each second electrode 130A is strip.As shown in figure 11, the shape of each first electrode 120A and each second electrode 130A can be all strip.
In addition, contact panel 300 comprises two bonding lands A31, A32.Relative two ends of each first electrode 120A are connected with first wire 140 separately, and be concentrated in the A31 of bonding land with the first wire 140 that the relative end near bonding land A31 of the first electrode 120A connects, and be concentrated in the A32 of bonding land with the first wire 140 that the relative end near bonding land A32 of the first electrode 120A connects.On the other hand, relative two ends of each second electrode 130A are connected with second wire 150 separately, and be concentrated in the A31 of bonding land with relative the second wire 150 connected near the second electrode 130A of bonding land A31, and be concentrated in the A32 of bonding land with relative the second wire 150 connected near the second electrode 130A of bonding land A32.
In the present embodiment, the width of each first electrode 120A is same as the width of each second electrode 130A, but is not limited thereto.In another embodiment, the width of each first electrode 120A can be different from the width of each second electrode 130A.For example, the width that can make the drive electrode (the wherein one of the first electrode 120A and the second electrode 130A) transmitting drive singal is greater than to transmit the width of the receiving electrode (the wherein another one of the first electrode 120A and the second electrode 130A) of sensing signal, and the space between adjacent two receiving electrodes can arrange test pattern (dummypattern), with the light transmittance that homogenizing is interregional, contact panel is made to have more uniform visual effect.
In sum, in the embodiment stated on the invention, the first electrode and the second electrode are arranged on thickness can lower than on the polyimide bearing bed of 50 μm, and therefore the integral thickness of contact panel can reduce effectively.In addition, insulation course due to contact panel is sequential like film and is be covered in the photic zone at the first electrode and the second electrode place by entire surface, wherein the first electrode and the second electrode lay respectively at relative two of insulation course on the surface, and therefore the above embodiments of the present invention can avoid the disconnection problem that the intersection of the first electrode and the second electrode is caused because of cross-line.Therefore the contact panel of the above embodiment of the present invention can be relatively frivolous and reliability is good.
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
