Optionally, as shown in figure 4, connecting bridge 6 covers transmission region 2.Connecting bridge 6 is located at transparent electrode layer 41, that is, connects
Bridge 6 is transparent material, when connecting bridge 6 covers transmission region 2, be can be avoided since transparent electrode layer 41 is in transmission region 2
Patterning and the problem that causes the transmitance in transmission region 2 inconsistent, improve the homogeneity that light penetrates in transmission region 2.
Optionally, as shown in Fig. 2, 2 no overlap of transparent electrode layer 41 and transmission region.In structure shown in Fig. 2, transparent area
Not set transparent electrode layer 41 at domain 2 further increases light transmission under the premise of light penetrates homogeneity in guaranteeing transmission region 2
Light transmission rate in region 2.
Optionally, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, each first touch control electrode 401 is close to one end of first edge P1
Vacantly, i.e. the top of each first touch control electrode 401 is not connected to arbitrary signal line in structure shown in Fig. 2 and Fig. 4；Each first
Touch control electrode 401 is electrically connected to corresponding touch control electrode signal wire (not shown), touch-control close to one end of second edge P2
Electrode signal line is electrically connected to driving chip (not shown).
Specifically, in Fig. 2 and Fig. 4, since corresponding first touch control electrode 401 of transmission region 2 is located at transmission region 2
Lower section, therefore, first touch control electrode 401 can not be attached with the signal wire in 1 top frame region of display area, because
This is arranged each first touch control electrode 401 and will not to guarantee the consistency of the transmitted signal of each first touch control electrode 401
In upper end connection signal line, i.e., hanging setting, only in lower end connection signal line, i.e., each first touch control electrode 401 is close to second
The end point of edge P2 is connected to corresponding touch control electrode signal wire, thus realize the first touch control electrode 401 and driving chip it
Between signal transfer functions.
Optionally, the both ends of each second touch control electrode 402 are electrically connected to corresponding touch control electrode signal wire.

One end of pole 402 is hanging, and other end is electrically connected to corresponding touch control electrode signal wire, to realize the transmission of touching signals, this
When, the first touch control electrode 401 and second touch control electrode 402 are unilateral driving, and the first touch control electrode 401 is driving electrodes, the
Two touch control electrodes 402 are induction electrode；Alternatively, the first touch control electrode 401 is induction electrode, second touch control electrode 402 is driving
Electrode.It should be noted which end is hanging for each second touch control electrode 402, which end connection touching signals line is equal
Can, it can according to need and be configured, for example, 402 left end of second touch control electrode of all odd-numbered lines is hanging, right end connects touch-control
Signal wire, 402 left end of second touch control electrode connection touching signals line, the right end of all even number lines are hanging.
Optionally, display panel is flexible display panels.When display panel is flexible display panels, the thickness of display panel
Available space is bigger on degree direction, and therefore, transparent electrode layer 41 can be set thicker, at this point, the resistance of transparent electrode layer 41
Rate is low, and the ability that transparent electrode layer 41 is formed by the first touch control electrode 401 transmission signal is stronger, therefore, uses unilateral driving
Mode will not lead to the deterioration of touch-control performance, therefore, the side of the unilateral driving of the first touch control electrode 401 in the embodiment of the present invention
Case is more applicable for flexible display panels.

Specifically, in Fig. 5, make since the transparent electrode layer 41 of 2 top of transmission region is not re-used as the first touch control electrode
With, and it is for connection to the first touch control electrode block 51 and second touch control electrode block 52 of 2 left and right sides of transmission region, such first
Length between touch control electrode block 51 and the first touch control electrode 401 for realizing capacity coupled face edge reduces, equally
The reason of, for realizing the length at capacity coupled face edge between second touch control electrode block 52 and the first touch control electrode 401
It reduces, so as to cause the first touch control electrode block 51 and second touch control electrode block 52, in touch-control, generated curent change becomes smaller
, therefore in order to compensate for the first touch control electrode block 51 and second touch control electrode block 52 in touch-control generated curent change, make
First touch control electrode block 51 and/or second touch control electrode block 52 are used as the first special-shaped electrode block 71, with the first special-shaped electrode block 71
Touch control electrode block corresponding to the first adjacent touch control electrode 401 is arranged between the two at least as the second special-shaped electrode block 72
One edge increases the length at face edge between the two in such a way that dentalation phase interfix refers to setting, that is, improves the
One special-shaped electrode block 71 generated curent change in touch-control, so as to improve the touch-control performance at transmission region 2.
