Carry out touch-control sensing.Those skilled in the art can also realize more touch control manners, and it will not be described here.
Each touch-control cabling includes the first sub- cabling 221, the second sub- cabling 223 and the sub- cabling 222 of bending.First son is walked
Line 221 is located at the first surface 203 of the array substrate 206.One end of the sub- cabling 221 of described the first of each touch-control cabling connects
Touch control electrode 210.The other end of the sub- cabling 221 of the first of each touch-control cabling is parallel to each other.Second sub- cabling 223 is located at the battle array
The second surface 205 of column substrate 206.One end of described second sub- cabling 223 of each touch-control cabling connects the flexible electrical
Road plate 230.Described second sub- cabling 223 of each touch-control cabling is parallel to each other.Each second sub- cabling 223 passes through connection pad
240 are connected to the flexible circuit board 230, and each connection pad 240 is located at the second surface 205 of the array substrate 206.Bending
Sub- cabling 222 is bent to the described second sub- cabling 223 from the described first sub- extension of cabling 221.The bending of each touch-control cabling
Sub- cabling 222 is parallel to each other.The crooked process radius for bending sub- cabling is general≤0.5mm, it is de- for the weld pad that prevents bending from causing the back side
It falls, the length for bending sub- cabling 222 need to be greater than 2mm.The length of cabling 223 is without specific limitation.Specifically, bending is walked
The first surface 203 for extending perpendicularly to the array substrate 206 and second surface 205 (as shown in Figure 4) of line 222.
It is appreciated that the width (such as 10 to 20 microns) of touch-control cabling is much smaller than flexible circuit board 230 and connection pad 240
Width, therefore, touch-control cabling is more resistant to bending.The present invention avoids bending from being related to flexible electrical by mode as shown in Figures 2 to 5
Road plate 230 and connection pad 240, and then prevent the metal fracture generated due to flexible circuit board 230 and the bending of connection pad 240 or bending de-
It falls, further improves the touch function of touch panel.In addition, by above-mentioned set-up mode, so that by 201 shape of touch control electrode array
At the distance between boundary to the boundary of touch panel 202 of touch area reduced compared to the prior art, for example, can
So that the distance between the boundary of the touch area to boundary of the touch panel be greater than 1.5 millimeters less than 2.5 millimeters,
And then realize display device narrow frame.
In some change case of the invention, at least bend sub- cabling can be it is patterned, but the present invention not with this
It is limited, the other parts of touch-control cabling can also be patterned.Sub- cabling is bent not by Fig. 6 to Fig. 9 description separately below
With patterned embodiment.
Referring first to Fig. 6 and Fig. 7, bending sub- cabling 222 has along the more of sub- 222 extending direction of the cabling arrangement of the bending
A through-hole 229.Through-hole 229 has rectangle (such as Fig. 6), diamond shape (such as Fig. 9), circle, elliptical shape.Further, bending is walked
The boundary of line 222 can be adapted to reduce the width for bending sub- cabling 222 with the boundary of through-hole 229.
Further, in Fig. 6 and embodiment shown in Fig. 7, the sub- cabling 222 of each bending from the array substrate
The part that is bent to the second surface of first surface and/or each sub- cabling 222 of bending from the array substrate
The part that second surface is bent to the first surface has 229 (the dotted line institute of the part of bending such as Fig. 6 and Fig. 7 of through-hole
Show).In this way, the width for bending the part that sub- cabling 222 is bent can be made minimum, thus improves and bend sub- cabling 222
Bending resistance.It, can be only in the bending part setting through-hole for bending sub- cabling 222 to subtract in a change case of Fig. 6 and Fig. 7
Few making technology bring scale error, and reduce since entire touch-control cabling patterning bring resistance increases, and then reduce
Touching signals delay, reinforces touch function.In there are some embodiments, through-hole only is set in the bending part of such as Fig. 6 and Fig. 7
229。
In the following, bending sub- cabling 222 with fold-line-shaped pattern referring to Fig. 8 and Fig. 9.For example, it may be as shown in Figure 8
Linear type broken line pattern or arc line shaped broken line pattern as shown in Figure 9, the present invention are not limited thereto.Make to bend sub- cabling 222
The width that part bends sub- cabling 222 can be reduced with fold-line-shaped pattern.
Further, in Fig. 8 and embodiment shown in Fig. 9, the sub- cabling 222 of each bending from the array substrate
The width of part that is bent to the second surface of first surface and/or each sub- cabling of bending from the array substrate
The width of part that is bent to the first surface of second surface be the sub- cabling of bending the minimum widith (part of bending
As shown in the dotted line of Fig. 8 and Fig. 9).In this way, the width for bending the part that sub- cabling 222 is bent can be made minimum, thus
Improve the bending resistance for bending sub- cabling 222.
The sub- cabling of patterned bending shown in Fig. 6 to Fig. 9 includes but is not limited to that the technologies such as photoetching, coining, transfer are realized.
Compared with prior art, the present invention improves pixel array and shows indistinct black line by improving pixel arrangement
Or to lead to the problem of shown straight line jagged.The present invention can also be alleviated shown jagged when showing oblique line
Problem.
It is particularly shown and described exemplary embodiments of the present invention above.It should be understood that the present invention is not limited to institute
Disclosed embodiment, on the contrary, it is intended to cover comprising various modifications within the scope of the appended claims and equivalent set
It changes.
