When in the electronic device that touch panel 100 is applied to display function, touch panel 100 corresponds to electronic device
Display picture can define viewing area 103, viewing area 103 is contained in central area 101.Electronic device may be provided with pair
The ink layer that the region between central area 101 and viewing area 103 should be covered, to avoid centrally located area 101 and viewing area 103 it
Between region in element observed by the user of electronic device.
Such as Fig. 1, touch panel 100 can also define an ink layer tolerance line 104, ink layer tolerance line 104 and display
The distance between the adjacent one side in area 103 is the ink layer margin of tolerance that its edge allows in fitting, ink layer tolerance line
Between 104 centrally located areas 101 and viewing area 103.
In one embodiment, in the region between third cabling 1721 and centrally located area 101, with viewing area 103
Second sensing electrode 131 is least partially overlapped on the substrate 11, and the overlapping portion of third cabling 1721 and the second sensing electrode 131
Divide mutually insulated.
In one embodiment, each third cabling 1721 is respectively positioned on one of ink layer tolerance line 104 far from viewing area 103
The second sensing electrode 131 in region between side, third cabling 1721 and centrally located area 101 and ink layer tolerance line 104
It is least partially overlapped on the substrate 11, and the lap mutually insulated of third cabling 1721 and the second sensing electrode 131, to keep away
Exempt from ink layer and exposes third cabling 1721 because fitting generates tolerance.Therefore, third cabling 1721 not may be positioned only at peripheral region
102, it can also be at least partially disposed in the region between central area 101 and viewing area 103.
In one embodiment, in the region between centrally located area 101 and ink layer tolerance line 104, is not only ensured
Three cablings 1721 can be covered by ink layer, also add the wiring space of third cabling 1721, make the of third cabling 1721
Two parts 1702 in peripheral region 102 there is enough spaces to be able to prolong along first direction (X-direction in Fig. 1) in third cabling 1721
It is long, meanwhile, third connection gasket 1821 peripheral region 102 also have enough spaces be increased its along first direction length.
Therefore, in the case where the width of third connection gasket 1821 (Y-direction in Fig. 1) in a second direction is constant, second
1702 are divided to increase achievable each along the length of first direction with corresponding third connection gasket 1821 along extending for first direction
The increase of overlapping area of the second part 1702 of third cabling 1721 with corresponding third connection gasket 1821 on the substrate 11, subtracts
Small required precision of second through-hole 162 on processing procedure effectively avoids third cabling 1721 from overlapping mistake with third connection gasket 1821
Accidentally, the use because of high precision apparatus is avoided to increase manufacturing cost.
Since electronic device may be provided with the ink layer in the region between corresponding covering central area 101 and viewing area 103, because
This, even if in region between 1721 centrally located area 101 of third cabling and viewing area 103 or centrally located area 101 and oil
In region between layer of ink tolerance line 104, third cabling 1721 will not be observed by user.
In one embodiment, although the third connection gasket 1821 of touch panel 100 in a first direction (X-direction in Fig. 1)
Length is increased, but since the 4th cabling 1722 and the 4th connection gasket 1822 are that (as shown in figures 1 and 3) is arranged in same layer,
Therefore, the length of the 4th connection gasket 1822 (X-direction in Fig. 1) in a first direction should not be too large, to avoid occupying the 4th too much
The wiring space of cabling 1722.In the present embodiment, the length of the 4th connection gasket 1822 (X-direction in Fig. 1) in a first direction is small
In the length of third connection gasket 1821 (X-direction in Fig. 1) in a first direction.
As shown in Figure 1, in the present embodiment, the length of the 4th connection gasket 1822 (X-direction in Fig. 1) in a first direction is less than
The length of third connection gasket 1821 (X-direction in Fig. 1) in a first direction, therefore, in order to not influence the arrangement of the 4th cabling 1722
Space, in one embodiment, when third connection gasket 1821 and the 4th connection gasket 1822 are at least partially disposed at the same of touch panel 100
When a side, every 1 the 4th connection gasket 1822 in the side is more leaned on compared to each third connection gasket 1821 of same side
Nearly driving circuit 19.
Therefore, it is more leaned on compared to each second part 1702 of same side in each Part IV 1704 of the side
Nearly driving circuit 19, the 4th cabling 1722, which needs not move through third connection gasket 1821, can be connected to driving circuit 19, will not should be
The increase of the length of third connection gasket 1821 in a first direction causes wiring space to reduce.
It will illustrate the touch panel 100 of first embodiment of the invention with specific data as follows.
Referring again to Fig. 1 and Fig. 2.In the present embodiment, between central area 101 and the adjacent side of viewing area 103
Distance definition is D1, D1=250 μm.The distance definition of central area 101 and adjacent ink layer tolerance line 104 is D2, D2=150
μm.The tolerance model that the distance between ink layer tolerance line 104 and adjacent one side of viewing area 103 allow when being bonded for ink layer
It encloses, in the present embodiment, the margin of tolerance that ink layer allows when being bonded is D1-D2=100 μm.
The first part 1701 of third cabling 1721 is at least partly arranged in central area 101 and ink layer tolerance line 104
Between, then self-corresponding first part 1701 extends second part 1702 to the direction far from central area 101.Therefore, first
1701 arrangement space is divided to be at least D2=150 μm, in one embodiment, near a third of ink layer tolerance line 104
The first part 1701 of cabling 1721 is 50 μm at a distance from ink layer tolerance line 104, wherein the of one article of third cabling 1721
Two parts 1702 along first direction development length be D3, D3=250 μm.
In one embodiment, the area that first part 1701 not only can be between central area 101 and ink layer tolerance line 104
Arrange in domain, first part 1701 can also wrap to arrange in peripheral region 102, with the third connection gasket 1821 of peripheral region perpendicular to
It is overlapped on the direction of substrate 11.
Third connection gasket 1821 along first direction development length be D4, D4=235 μm.Second through-hole 162 is along first party
To development length be D5, D5=50 μm.In the present embodiment, second part 1702 and third connection gasket 1821 are perpendicular to base
The length of overlapping on the direction of plate 11 be D6, D6=200 μm.That is, the second through-hole 162 can open up ranging from
200μm。
Referring again to Fig. 1 and Fig. 3, in the present embodiment, peripheral region 102 is D7=240 μm along the length of first direction,
Part III 1703, Part IV 1704 and the 4th connection gasket 1822 of 4th cabling 1722 are respectively positioned on peripheral region 102.At this
In embodiment, the 4th connection gasket 1822 is D8=110 μm along the length of first direction, then the 4th cabling 1722 is in peripheral region 102
Length along the arrangement space of first direction is D9=D7-D8=130 μm.
It can be seen that third connection gasket 1821 is more than the 4th connection gasket 1822 along first direction along the length D4 of first direction
Length D8, connected up since at least partly region of central area 101 is utilized in third cabling 1721, in the present embodiment,
Three cablings 1721 along the wiring space of first direction be 102 region of peripheral region plus central area 101 and ink layer tolerance line 104 it
Between region, that is, third cabling 1721 along the wiring space of first direction length be D2+D7=390 μm.
Therefore, in the case of the line width and constant line-spacing of the first part 1701 of third cabling 1721, third cabling
1721 second part 1702 also has more spaces to be extended.At the same time, third connection gasket 1821 in a second direction
In the case that the width of (Y-direction in Fig. 1) is constant, the extension of second part 1702 is with corresponding third connection gasket 1821 along first
The second part 1702 that the length in direction increases achievable each third cabling 1721 exists with corresponding third connection gasket 1821
The increase of overlapping area on the direction of substrate 11 reduces required precision of second through-hole 162 on processing procedure, effectively
