In barrier water oxygen to damage caused by luminescent device, and then be conducive to be promoted the performance reliability of flexible display panels 100.
Optionally, please continue to refer to Fig. 4, flexible display panels 100 further include support portion 23, in the second condition, support
First face 231 in portion 23 is located at the array layer 50 in reflexed area 32 far from 10 side of flexible base board.
Specifically, flexible display panels 100 further include having support portion 23, in the second condition, the first face of support portion 23
231 are located at the array layer 50 in reflexed area 32 far from the side of flexible base board 10, for playing support to the reflexed area 32 after bending
With the effect of protection, after flexible display panels are depressed, which can guarantee the second metal in reflexed area 32
Layer 22 does not change with the deformation of body region 30, i.e. the position of second metal layer 22 is fixed, along perpendicular to 10 institute of flexible base board
In the direction of plane, the first metal layer 21 as caused by the pressing of body region display panel is subjected to displacement, so as to cause the first gold medal
Belong to layer 21 to be subjected to displacement with respect to second metal layer 22, the distance between the first metal layer 21 and second metal layer 22 reduce, capacitor
Become larger, to realize the detection to touch pressure.It should be noted that Fig. 4 is only schematically to embody support portion 23 and anti-
Relative positional relationship between the array layer of folding area 32 does not represent actual size.
It should be noted that in some other embodiment of the application, in the second condition, the array layer in reflexed area
It may also include OCA (Optically Clear Adhesive) glue between body region, using OCA glue by space between the two
It is filled, so as to effectively avoid impurity from entering the measurement of influence capacitor in the space.
Optionally, Fig. 9 and Figure 10 are please referred to, a kind of DD ' that Fig. 9 show display panel provided by Fig. 7 embodiment is cut
Face figure, Figure 10 show a kind of main view of display panel provided by Fig. 7 embodiment, i.e. Figure 10 is Fig. 7 along first direction
Main view；Support portion 23 further includes the second face 232, and in a third condition, the second face 232 of support portion 23 is located at extension area 31
Flexible base board 10 is far from array layer side；The third state is the flexibility positioned at the flexible base board 10 of extension area 31 towards extension area 31
Substrate 10 is bent far from the side of array layer.
Specifically, the second face of support portion 23 is located at the flexible base board 10 of extension area 31 far from the side of array layer 50, such as
This, support portion 23 can effectively prevent the array layer 50 of extension area 31 to 30 flexible base board 10 of body region far from array layer 50 one
Side reflexed, so that the array layer 50 to extension area 31 plays preferable fixed function.In this way, support portion 23 can not only support
Second metal layer 22, make second metal layer 22 will not due to pressing display panel body region and relative displacement occurs and (such as asks
Referring to fig. 4), additionally it is possible to support the corresponding array layer 50 of the extension area under the third state.It should be noted that Fig. 9 is only schematic
Ground gives the relative positional relationship of flexible base board 10 Yu array layer 50, does not represent the practical film layer structure and ruler of array layer 50
It is very little.In addition, referring to Figure 10, when pressing main part 30, the array layer in reflexed area 32 is fixed, and main part 30 is by phase
Relative displacement is occurred for the array layer in reflexed area 32, so that the in the first metal layer and reflexed area 32 in body region 30
Distance changes between two metal layers, so that the capacitor C formed therebetween occurs to become corresponding change, to realize
The pressure detecting function of flexible display panels 100.
Optionally, it is less than referring to figure 4. with Figure 10, support portion 23 in the area of the orthographic projection of 10 place plane of flexible base board
Equal to reflexed area 32 array layer 50 10 place plane of flexible base board orthographic projection area.
Specifically, it when the application is fixed using support portion 23 come the second metal layer 22 to reflexed area 32, only needs true
The orthographic projection that support portion 23 is protected in 10 place plane of flexible base board covers second metal layer 22, i.e., rises to second metal layer 22
It is acted on to comprehensive support, even if flexible display panels 100 are also ensured that 22 phase of second metal layer by pressed by external force at this time
Flexible base board 10 will not be subjected to displacement.Under the premise of herein, when by support portion 23 10 place plane of flexible base board positive throwing
The area of shadow is less than or equal to the array layer 50 in reflexed area 32 in the area of the orthographic projection of 10 place plane of flexible base board, support portion
23 can either play preferable supporting role to second metal layer 22, while its area is also unlikely to too big, to be conducive to save
About production cost.
Optionally, the elasticity modulus of support portion 23 is E, E >=1GPa.
Specifically, as elastic modulus E >=1GPa of support portion 23, support portion 23 is rigid material, so that reflexed area
32 and the array layer of extension area 31 have certain rigid power-assisted, thus it is advantageously ensured that reflexed area 32 and extension area 31 it is soft
Property substrate 10 be not easy because external force and deformation occurs.
It should be noted that in some other embodiments of the application, the array layer 50 of support portion 23 and reflexed area 32
Between may also include protective layer, meanwhile, protective layer can also be protected between the array layer 50 of support portion 23 and extension area 21, the protection
Layer can play the role of buffering, avoid array layer and directly contact with the support portion of rigidity and impact to array layer.
