The flexible display screen that embodiment provides can make full use of the space in seal ring thickness direction, to subtract when carrying out conduct piece wiring
The small quantity that conduct piece is arranged along border width direction, this makes it possible to while not increasing display device border width,
Ensure that flexible lead wire 1 realizes complete binding with circuit board 2.In other words, in the case that border width is certain, the utility model is real
The flexible display screen for applying example offer is applied to flexible display apparatus, enables to the lead that display device array is drawn more
Realize binding.
It is understood that the signal that trace layer is transmitted in the utility model embodiment can be answered according to flexible display screen
Environment is different.Such as：The flexible display screen that the utility model embodiment provides is applied in the array substrate of display device,
The signal that each trace layer is transmitted in flexible lead wire 1 is source-drain electrode signal.
And in order to enable short circuit do not occur for each trace layer in flexible lead wire 1, mutually insulated between multiple trace layers.Such as figure

Specifically including has insulating layer between two neighboring trace layer, and the end face structure that each insulating layer is located at trace layer exit is exhausted
The end face structure on edge inclined-plane, the exit of each trace layer is conductive inclined-plane, and conductive inclined-plane and the trace layer of trace layer deviate from rank
The insulation inclined-plane for the insulating layer that the surface in halfpace face is contacted, which is formed, connects inclined-plane, between the ladder table top of two neighboring trace layer
There are one connect inclined-plane for tool, it can be seen that, in the utility model embodiment flexible lead wire 1, the electricity between two neighboring binding face
The plate inclined-plane corresponding connection inclined-plane between the ladder table top of two neighboring trace layer in road is opposite, so that flexible lead wire 1 and electricity
When road plate 2 interacts, the active force that flexible lead wire 1 acts on the circuit board 2 can be divided by circuit board inclined-plane
The active force in vertical direction (perpendicular to the binding face of circuit board 2) and horizontal direction, to reduce circuit board 2 in the horizontal direction
The displacement of generation, while the active force that circuit board 2 acts on flexible lead wire 1 is divided into vertical direction and water by connecting inclined-plane
Square to active force, to reduce the position that flexible lead wire 1 occurs in the horizontal direction.
In view of the stability of flexible lead wire 1, as shown in figure 3, when ladder-like arrangement is presented in multiple trace layers, Duo Geyin

As shown in Figure 9 and Figure 10, when the utility model embodiment provide flexible display screen be applied to display device in,
When display device is bent towards display surface direction (bending direction is as shown in Fig. 9 arrow directions), each of flexible lead wire 1 draws
The force direction that line contact is applied towards the corresponding each binding face of circuit board 2 towards Figure 10 upper right, and according to
Force resolution towards the active force of upper right it is found that can be decomposed into upward active force in Figure 10, and effect to the right
Power, and due to the circuit board inclined-plane correspondence between two neighboring binding face and the company between the ladder table top of two neighboring trace layer
Connect inclined-plane have adjust gap so that circuit board 2 by Figure 10 upper rights active force when, can be by suffered active force
Being converted to the active force for promoting circuit board 2 to movement on the right side of Figure 10 so that the gap width for adjusting gap increases, this makes it possible to
Circuit board 2 is reduced because of stress caused by display device bending.
In view of the circuit board inclined-plane between two neighboring binding face correspond to the ladder table top of two neighboring trace layer it
Between connection inclined-plane it is opposite when, the circuit board inclined-plane between two neighboring binding face corresponds to the ladder platform with two neighboring trace layer
Connection inclined-plane between face, which has, adjusts gap, stress caused by circuit board 2 when can reduce display device bending, and is drawing
In the case of the extraction end area of line layer is increased, in display device towards when being bent away from the direction of display surface, even if circuit board 2
Circuit board inclined-plane and be correspondingly connected with contact of incline plane, can also reduce impact force of the circuit board 2 to the exit of trace layer.Separately
Outside, in the case of the extraction end area of trace layer is increased, the cross section equivalent to increase trace layer so that each trace layer
Resistance reduce, to improve the accuracy of signal transmission.
As shown in figure 4, in the flexible display screen that the utility model embodiment provides, what is gone out given in flexible lead wire 1 draws
