The flexible display panel 100 provided by an embodiment of the present application includes a first flexible display layer 10 and a second flexible display layer 30 which are stacked, where the first flexible display layer 10 includes a plurality of first pixel modules 11, the second flexible display layer 30 includes a plurality of second pixel modules 31, and the first pixel modules 11 and the second pixel modules 31 are used for emitting light, so as to realize that the flexible display panel 100 displays an image. As shown in fig. 2, when the flexible display panel 100 is stretched and deformed, the second pixel module 31 is disposed corresponding to the first gap 12, and light from the second pixel module 31 can exit through the first gap 12.
Since the size of the first gap 12 in the force-receiving direction increases when the flexible display panel 100 is deformed by stretching, the density of the arrangement of the first pixel modules 11 decreases, and the flexible display panel 100 has a reduced resolution. And the flexible display panel 100 that this application provided, through setting up the second flexible display layer 30 that includes a plurality of second pixel modules 31, when flexible display panel 100 is by tensile deformation, second pixel module 31 corresponds the setting with first clearance 12, the light from second pixel module 31 can pass through first clearance 12 outgoing, made up first pixel module 11 because of the resolution ratio reduction phenomenon that the tensile caused, so, the resolution ratio after flexible display panel 100 is by tensile deformation has been improved to a certain extent, flexible display panel 100's display performance has been improved, and make flexible display panel 100 can buckle, stretch, realize more deformation forms, promote user's experience.
In this embodiment, the first pixel module 11 and the second pixel module 31 may be, but not limited to, an organic light emitting device or a liquid crystal display device.
In the present embodiment, as shown in fig. 3, a second gap 32 is formed between adjacent second pixel modules 31. The first pixel module 11 and the second pixel module 31 have substantially the same structure. When the flexible display panel 100 is not stretched and deformed, the second pixel modules 31 and the first pixel modules 11 are arranged in a one-to-one correspondence manner, the first gaps 12 and the second gaps 32 are arranged in a one-to-one correspondence manner, and the second pixel modules 31 are hidden at the lower sides of the first pixel modules 11, so that the display effect of the first pixel modules 11 is not affected. As shown in fig. 2, when the flexible display panel 100 is stretched and deformed, the second pixel module 31 moves and is misaligned relative to the first pixel module 11, so that the second pixel module 31 is disposed corresponding to the first gap 12, and the resolution reduction phenomenon of the first pixel module 11 caused by stretching is compensated.
It is understood that the second pixel module 31 is shifted and dislocated relative to the first pixel module 11, including the situation where the first pixel module 11 is shifted and the second pixel module 31 is not shifted, so that the second pixel module 31 is dislocated; the first pixel module 11 does not move and the second pixel module 31 moves, so that a misalignment situation occurs; and a case where the first pixel module 11 and the second pixel module 31 are moved by different distances, respectively, and thus are misaligned.
It is understood that when the flexible display panel 100 is not deformed by stretching, the first gap 12 may be 0, that is, adjacent first pixel modules 11 may contact each other. It is understood that when the flexible display panel 100 is not deformed by stretching, the second gap 32 may be 0, that is, adjacent second pixel modules 31 may contact each other. It is understood that the shape and size of the first pixel module 11 and the second pixel module 31 are not limited to be substantially the same, for example, the shape and size of the first pixel module 11 may be different from the second pixel module 31. It can be understood that, when the flexible display panel 100 is not stretched and deformed, the second pixel modules 31 and the first pixel modules 11 are not limited to be arranged in a one-to-one correspondence, for example, in an alternative embodiment, when the flexible display panel 100 is not stretched and deformed, the second pixel modules 31 are arranged in a staggered manner relative to the first pixel modules 11, that is, the second pixel modules 31 are arranged in correspondence to the first gaps 12, because the first gaps 12 are not yet increased at this time, the second pixel modules 31 are not likely to affect the display effect of the first pixel modules 11, and in the process of stretching and deforming the flexible display panel 100, the first pixel modules 11 move along the force-receiving direction, the size of the first gaps 12 in the force-receiving direction is increased, the second pixel modules 31 are still arranged in correspondence to the first gaps 12, and light emitted from the second pixel modules 31 can be emitted through the first gaps 12.
Specifically, the first flexible display layer 10 further includes a first flexible substrate 13 and a first stretchable connecting line 15, the plurality of first pixel modules 11 are fixed and disposed on the first flexible substrate 13 at intervals, and the first flexible substrate 13 is located between the first pixel modules 11 and the second flexible display layer 30. The adjacent first pixel modules 11 are fixedly connected by a first stretchable connecting line 15, and the first stretchable connecting line 15 is used for establishing electrical connection between the adjacent first pixel modules 11. The first flexible substrate 13 is used for carrying the first stretchable connecting line 15 and the first pixel module 11, and meanwhile, the first flexible substrate 13 can be deformed by being stressed to meet the flexibility characteristic of the flexible display panel 100.
In the present embodiment, the first stretchable connecting line 15 is disposed in a wave shape, so that when the flexible display panel 100 is stretched and deformed, resulting in an increase in the distance between the adjacent first pixel modules 11 (i.e., the first gap 12), a buffer space can be provided for the first stretchable connecting line 15, so that the first stretchable connecting line 15 is not easily broken. It is to be understood that the first stretchable connecting line 15 is not limited to be provided in a wave shape, for example, the first stretchable connecting line 15 may also be provided in a horseshoe shape, a zigzag shape, or the like.
The first flexible substrate 13 includes a plurality of first fixing portions 131 and a plurality of first elastic portions 133 connected to each other, the first pixel module 11 is disposed on the first fixing portions 131, and the first fixing portions 131 are used for bearing the first pixel module 11. The first stretchable connecting line 15 is embedded on the first elastic portion 133, and both the first elastic portion 133 and the first stretchable connecting line 15 are made of a transparent material. The first elastic portion 133 can be deformed by a force, and drives the first fixing portion 131 to move, so that the first pixel module 11 moves, and the flexible display panel 100 has a stretching property. In the present embodiment, since the first elastic portion 133 is made of a light-transmitting material, the first elastic portion 133 has a light-transmitting property, and when the flexible display panel 100 is stretched and deformed, light from the second pixel module 31 can be emitted from the first gap 12 through the first elastic portion 133. Moreover, the first stretchable connecting wire 15 embedded in the first elastic portion 133 can not block the light from the second pixel module 31, thereby facilitating the light of the second pixel module 31 to exit from the first elastic portion 133.
It is understood that the first stretchable connecting line 15 is not limited to be made of a light-transmitting material, for example, in an alternative embodiment, the arrangement position of the first stretchable connecting line 15 may be changed, so that the first stretchable connecting line 15 does not affect the light emitted from the second pixel module 31.

The second flexible substrate 33 is used for carrying the second stretchable connecting line 35 and the second pixel module 31, and meanwhile, the second flexible substrate 33 can be stretched to deform, so as to meet the flexibility characteristic of the flexible display panel 100. The second stretchable connecting line 35 is used to establish electrical connection between the adjacent second pixel modules 31.
In this embodiment, the second stretchable connecting line 35 is disposed in a wave shape, so that when the flexible display panel 100 is stretched and deformed to increase the distance between the adjacent second pixel modules 31, a buffer space is provided for the second stretchable connecting line 35, so that the second stretchable connecting line 35 is not easily broken. It is to be understood that the second stretchable connecting line 35 is not limited to be arranged in a wave shape, for example, the second stretchable connecting line 35 may also be arranged in a horseshoe shape, a zigzag shape, or the like.
The second flexible substrate 33 includes a plurality of second fixing portions 331 and a plurality of second elastic portions 333, the second pixel module 31 is disposed on the second fixing portions 331, and the second stretchable connecting wire 35 is embedded on the second elastic portions 333. The second fixing portion 331 is used for carrying the second pixel module 31. The second elastic portion 333 is used to enable the second flexible substrate 33 to be stretched and deformed to drive the second fixing portion 331 to move, so as to drive the second pixel module 31 to displace.
It is understood that the second stretchable connecting line 35 may not be made of a light-transmissive material.
In this embodiment, the elastic modulus of the first elastic part 133 is greater than that of the second elastic part 333, so that the second pixel module 31 can move and shift relative to the first pixel module 11 after the flexible display panel 100 is stretched and deformed.
It is to be understood that the elastic modulus of the first elastic portion 133 is not limited to be larger than the elastic modulus of the second elastic portion 333, for example, the elastic modulus of the first elastic portion 133 may be smaller than the elastic modulus of the second elastic portion 333, that is, the second pixel module 31 can move and shift relative to the first pixel module 11 after the flexible display panel 100 is stretched and deformed.

In this way, the first elastic part 133 and the second elastic part 333 are designed in a gradient manner such that the elastic modulus of the first elastic part 133 is greater than the elastic modulus of the second elastic part 333.
It is understood that the pattern of the patterned first elastic part 133 may also be as shown in fig. 5, and the pattern of the patterned second elastic part 33 may also be as shown in fig. 4. It is understood that fig. 4 and 5 only show two possible patterning manners for example, and the patterned patterns of the first elastic portion 133 or the second elastic portion 33 may be other patterns.
It is understood that the first and second elastic parts 133 and 333 are not limited to being simultaneously prepared by a patterning method, for example, in an embodiment, the first elastic part 133 is prepared by a patterning method. In one embodiment, the second elastic part 333 is prepared by a patterning method.
It is understood that, in the modified embodiment, the second elastic part 333 may be omitted, that is, the first flexible substrate 13 has elasticity, and the second flexible substrate 33 has no elasticity, and the second pixel module 31 on the second flexible substrate 33 is disposed to be aligned with the position of the first gap 12 after the flexible display panel 100 is stretched and deformed, so that when the flexible display panel 100 is stretched and deformed, the first pixel module 11 moves along the force-bearing direction, and even if the second pixel module 31 does not move, the second pixel module 31 can still be disposed corresponding to the first gap 12, so that the light emitted from the second pixel module 31 can be emitted through the first gap 12.
In the present embodiment, the first and second stretchable connecting lines 15 and 35 are made by a nano-scale multi-layer gradient process in which the elastic modulus of the first stretchable connecting line 15 is different from that of the second stretchable connecting line 35.
In the present embodiment, the first stretchable connecting line 15 and the second stretchable connecting line 35 include at least two layers stacked. As shown in fig. 6, taking the first stretchable connecting wire 15 as an example, the first stretchable connecting wire 15 includes a plurality of elastic layers 151 and conductive layers 153 stacked together, wherein the elastic layers 151 are made of an elastic material, for example, but not limited to, Polydimethylsiloxane (PDMS), thermoplastic polyurethane elastomer (TPU), or a high polymer material with a shape memory function. The conductive layer 153 is made of a conductive material, for example, in the present embodiment, the material of the first stretchable connecting wire 15 at least includes one of a nano silver wire, a conductive silver paste, or graphene.

It is understood that, in the present embodiment, the structure of the second stretchable connecting line 35 is similar to that of the first stretchable connecting line 15, and the material of the second stretchable connecting line 35 at least includes one of a nano silver wire, a conductive silver paste, and graphene. It is understood that the materials of the first stretchable connecting line 15 and the second stretchable connecting line 35 may not be limited to the above-mentioned materials, and materials capable of enhancing the stretching property or the electrical conductivity of the first stretchable connecting line 15 and the second stretchable connecting line 35 are within the scope of the present application.

The sensor 210 is configured to detect whether the second flexible display layer 30 is misaligned with respect to the first flexible display layer 10, and the processor 220 is configured to control the second flexible display layer 30 to display when the sensor 210 detects that the second flexible display layer 30 is misaligned with respect to the first flexible display layer 10.

For example, when the flexible display panel 100 is stretched and the first sensing module 211 detects that the second pixel module 31 moves to be dislocated relative to the first pixel module 11 by a dislocating distance greater than or equal to the set distance, the processor 220 controls to light the second flexible display layer 30; when the flexible display panel 100 is restored to the unstretched state, and the first sensing module 211 detects that the second pixel module 31 moves to be dislocated relative to the first pixel module 11 by a dislocating distance smaller than the set distance, the processor 220 controls to turn off the second flexible display layer 30.
