The bendable folding part 66 is extended on property substrate 61 and from the binding portion 65.
The binding portion 65 includes the first binding portion 651, the second binding portion 652.The first binding portion 651 and described
Separated between two binding portions 652 with interval trough 67.Reduce an interval trough 67 relative to conventional designs, so as to reduce described
The width in binding portion 65, can reach cost-effective purpose.
The line channel 62 includes first line passage 621, the tertiary circuit passage 623 and second being arranged side by side successively
Line channel 622.First circuit path 621 and the tertiary circuit passage 623 are located at the first binding portion 651, institute
State the second line channel 622 and be located at the second binding portion 652, and, the circuit projection of three line channels does not intersect.
Based on this, the circuit in each passage of the bendable folding part 66 could be provided as bilayer, therefore, the bendable folding part
The channel width shared by circuit in 66 is that the first line passage 621,623 and second circuit of tertiary circuit passage lead to
Channel width shared by the half of circuit total quantity in road 622.Relative to it is known it is used it is described can 66 individual layer of turn of bilge
Cabling designs, and reduces width of the bendable folding part 66 in X-direction.It can reduce used in the bending part 66 when installing complete machine
Through hole, and then saving space can make other more flexible designs of assembly parts size.Meanwhile the circuit projection in the line channel 62
Do not intersect design, the first line passage 621 described in the binding portion 65,623 and second circuit of tertiary circuit passage
Circuit in passage 622 is bilayer arrangement, occupies the width of the binding portion 65 in the Y direction by the first line passage
621st, the half of the circuit total quantity in 623 and second line channel 622 of tertiary circuit passage is uniformly divided in the binding portion 65
Cloth determines, makes the height reduction of the binding portion 65 in the Y direction relative to conventional designs, and then make the flexible circuit board 60
Crooked place moves down, and opposite adds the length of the bendable folding part 66 in the Y direction, and then can make the more flexible operation of installation.
In another embodiment, can also partly be used as needed positioned at the circuit of the binding portion 65 and the bendable folding part 66
Double-decker, in this way, difficulty of processing can be reduced while the size of the flexible circuit board 60 is reduced.
The flexible circuit board 60 is electrically connected with the pixel control layer 80 by way of binding, when being bound,

Circuit that second induction electrode lead 832 is electrically connected in the tertiary circuit passage 623, the driving electrodes lead 84 are electrically connected
Circuit in second line channel 622.
The base material of the flexible circuit board 60 is copper foil, the first line passage 621, the tertiary circuit passage of the inside
623 and the second circuit in line channel 622 equivalent to copper foil circuit.The line width of present process capability routine copper foil cabling in the industry
Line-spacing is 60/60mm, and limit line the wide line is away from for 40/40mm.The base material of the pixel control layer 80 is PET, the sense of the inside
Contact conductor 83 is answered to be generally elargol cabling with the driving electrodes lead 84, elargol cabling processing technology is more, can use erosion
Carving technology or photosensitive silver process, line width line-spacing can accomplish 30/30mm, even more carefully.
The width of the every induction electrode lead 83 is less than or equal to 0.1mm in the present embodiment；Every driving electrodes
The width of lead 84 is less than or equal to 0.03mm, therefore, the every induction electrode lead 83 and the every driving electrodes lead
84 projection intersection areas are less than or equal to 0.1*0.03, and i.e. intersection area is less than or equal to 0.003mm two-by-two2.So in the touch-control sense
Survey 80 enterprising walking line of layer to intersect, intersection area can be smaller than the cross facet intersected in the 60 enterprising walking line of flexible circuit board
Product, intersects moreover, can be also better than in performance in 60 upward wiring of flexible circuit board.In addition, in pixel control layer (especially
The pixel control layer of double-decker) on, induction electrode lead and the difficulty that driving electrodes lead intersects in projection well below
Flexible circuit board upward wiring intersects, therefore, it is easier to it is processed.
Above-mentioned touch screen 100, relative to known example, cabling crossover location is changed by designing originally in the flexible circuit board 60
To design the binding that in the pixel control layer 80, can make the flexible circuit board 60 that there is narrower bendable folding part 66, smaller
Portion 65 and the cabling intersection area of smaller, while performance is ensured, crooked place moves down, make it is easy for installation flexibly, reduce it is soft
Through hole used in plate, has saved complete machine space-saving processing procedure cost, meanwhile, the difficulty of processing is reduced, improves production efficiency.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses a kind of embodiment of the utility model, its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
