Divide the region for carving seam 14 and partially electronically conductive pattern 13." region of conductive pattern 13 " described in present specification is entirely conductive
The region that pattern 13 is covered.
When the transmitance difference for carving 14 regions of seam and the region of transparent conductive patterns 13 is less than 1%, transparent conductive patterns
13 is i.e. invisible, is that inventor is drawn by substantial amounts of experiment.It is unit that inventor, which chooses human eye and differentiates smallest dimension 0.1mm,
Length, the circular area of the square or a diameter of unit length by unit length of the length of side is unit area, by unit

Table 3
It can be seen that from the data of table 1, table 2, table 3：The transmitance for carving 14 regions of seam and the region of transparent conductive patterns 13 is poor
Different when being less than 1%, figure is invisible, and transmitance difference figure observability more than 1% is gradually obvious.
How to realize that the transmitance difference for carving 14 regions of seam and the region of transparent conductive patterns 13 is less than 1%, there are different implementations
Mode, is given below several preferred modes and is illustrated.
As a preferred embodiment, as shown in Figure 2 a, the electrically conducting transparent figure for the contact panel 10 that the present invention is provided
Case 13 can further comprise electrode wires 21 and electrode 22, and electrode wires 21 are connected with electrode 22, between electrode wires 21, electrode 22
14 are stitched with carving.Region 210 is the surface any region of contact panel 10, and it is the face that seam 14 is carved in region 120 to carve seam dutycycle X
The long-pending ratio with the area of region 120, Ta is the transmitance in 14 regions of quarter seam in the region 210, and Tb leads to be transparent in region 210
The transmitance in the region of electrical pattern 13.
For purposes of illustration only, exemplified by using glass as transparent substrates 11, the transmitance value of glass is 95%, is being carved in seam 14,
Only there are transparent substrates 11, therefore its transmitance is 95%；As shown in Figure 1 d, the transmitance in the region of transparent conductive patterns 13 is
90%, at the invisible border of figure, it is 20% that its abscissa, which carves seam dutycycle, and transmitance difference is just 1%；Electrically conducting transparent figure
The transmitance in the region of case 13 is 86%, at the invisible border of figure, and its abscissa is 11.7%, and now transmitance difference is 1%.
When the transmitance in the region of transparent conductive patterns 13 is 80%, quarter seam dutycycle appearance after 6.6% is visible, now transmitance difference
It is similarly 1%.
Also, when can also be seen that from Fig. 1 d data when 13 region transmitance increase of transparent conductive patterns, occur without figure
The visible maximum for carving seam dutycycle also increases therewith.According to calculating, when carving seam dutycycle design load no more than estimated value, i.e.,
Figure can be improved visible.The specific different estimated values for carving seam dutycycle X are as listed by table 4：
Table 4
It can be drawn by above-mentioned data and calculating, the quarter seam dutycycle of transparency conducting layer 12When, X
To carve 14 areas of seam and the ratio of unit area in unit area, 1% is the maximum of transmitance difference when figure is invisible, Ta
For it is described carve seam 14 regions transmitance, Tb be the region of transparent conductive patterns 13 transmitance, the region of transparent conductive patterns 13 with

Electrode wires 210 as shown in Figure 2 b（It is not shown）, 211,212, respectively including the first terminal 210a, 211a, 212a and
Second terminal 210b, 211b, 212b, the first terminal 210a, 211a, 212a are connected with electrode 220,221,222, Second terminal
210b, 211b, 212b are located at transparent substrates 11（It is not shown）Edge.First electrode line region 24a close to the first terminal 210a,
211a, 212a, electrode wires second area 24b is close to Second terminal 210b, 211b, 212b.In the 24a of electrode wires first area

In second electrode line region 24b quarter seam density variation, i.e. first electrode line region 24a in electrode wires inside have one or
It is multiple to carve seam.
Electrode wires 210 include the first terminal 210a and Second terminal 210b, the first terminal 210a and electrode as shown in Figure 2 c
220 are connected, and Second terminal 210b is located at transparent substrates 11（It is not shown）Edge.Electrode wires 211 include the first terminal 211a and the
Two-terminal 211b, the first terminal 211a is connected with electrode 221, and Second terminal 211b is located at the edge of transparent substrates 11, first electrode
Line region 24a is close to the first terminal 210a and 211a, and second electrode line region 24b is close to Second terminal 210b, 211b.Positioned at
There is multiple carve to stitch 210c, the electrode wires 211 positioned at first electrode area 24a have in one electrode wires region 24a electrode wires 210
There is one to carve seam 211c.The width that quarter slit width degree between electrode wires 210,211,212 stitches 210c and 211c with carving is essentially identical.
It is to optimize electrode structure to control the another way for carving seam dutycycle, reduces electrode wires number, and then seam is carved in reduction
Seam dutycycle is carved in number, reduction.
For the ease of carrying out comparative illustration, mode and optimal way will be had simultaneously.Existing mode as shown in Figure 3 a,
Electrode wires 21 include first electrode line 31 and second electrode line 32, and electrode 22 includes first electrode 33 and second electrode 34, first
Electrode 33 is spaced apart from each other with second electrode 34 along panel broadside or narrow edge direction, and defines this direction for line direction.First
Electrode wires 31 are connected with first electrode 33, and second electrode line 32 is connected with second electrode 34.First electrode 33 is hung down along with line direction
Straight column direction distribution is multiple, and second electrode 34 is per column distribution one.
As shown in Figure 3 b, first electrode 33 further comprises the first sub-electrode 33a and 33b, the first sub-electrode to optimal way
33a and 33b are spaced apart from each other along column direction.First electrode line 31 further comprises the first sub-electrode line 31a and 31b, point
It is not connected with the first sub-electrode 33a and 33b.Second electrode 34 further comprises the second sub-electrode 34a and 34b, the second sub-electrode

34a and 34b are staggered for pole, i.e., not in same row or column.Likewise, the first sub-electrode 33b of first electrode 33 and adjacent the
The the second sub-electrode 34a and sub-electrode 34b of two electrodes 34 are also staggered.
To embody the technique effect of optimal way, spy is given an example with concrete numerical value：If each column has in existing mode
There are 24 first electrodes and 1 second electrode, then optimal way reaches that identical touch-control effect needs each column to need 12 first
Electrode and 2 second electrodes, both there is 14 row, then corresponding electrode wires number is as shown in table 5：
| Each column first electrode line number mesh | Each column second electrode line number mesh | Total columns | Electrode wires sum | |
| Existing mode | 24 | 1 | 14 | 350 |
| Optimal way | 12 | 2 | 14 | 196 |
