The applicant provides a solution to the problems of the prior art through intensive research.
Fig. 1 is a schematic plan view of a stretchable display panel according to an embodiment of the present invention, fig. 2 is a schematic cross-sectional structure diagram of the stretchable display panel according to the embodiment of the present invention in a first stretching state, and fig. 3 is a schematic cross-sectional structure diagram of the stretchable display panel according to the embodiment of the present invention in a second stretching state.
As shown in fig. 1 to 3, the stretchable display panel 100 according to the embodiment of the present invention includes: a plurality of light emitting devices 10, a plurality of first reflective layer groups 01, and a plurality of second reflective layer groups 02.
The first reflection layer group 01 is located at one side of the light emitting surface of the film layer where the light emitting device 10 is located and includes a plurality of first reflection sheets 11, and the second reflection layer group 02 is located at one side of the light emitting surface of the film layer where the light emitting device 10 is located and includes a plurality of second reflection sheets 12. The first reflective layer group 01 and the second reflective layer group 02 may be configured to reflect at least a portion of light emitted from the light emitting device 10.
As shown in fig. 2 and 3, the inclination angles of the first reflective sheets 11 in the first reflective layer group 01 are different between the first stretched state and the second stretched state of the stretchable display panel 100. For example, as shown in fig. 2 and 3, when the stretchable display panel 100 is in the first stretched state, an included angle between the first reflective sheet 11 and the first direction Y is α; when the stretchable display panel 100 is in the second stretched state, an included angle between the first reflective sheet 11 and the first direction Y is α 2, α 1 ≠ α 2. Wherein, the first direction Y is a thickness direction of the stretchable display panel.
As shown in fig. 2 and 3, the inclination angles of the second reflective sheets 12 in the second reflective layer group 02 are different between the first stretched state and the second stretched state of the stretchable display panel 100. For example, as shown in fig. 2 and fig. 3, when the stretchable display panel 100 is in the first stretched state, an included angle between the second reflective sheet 12 and the first direction Y is α 3; when the stretchable display panel 100 is in the second stretched state, an included angle between the second reflective sheet 12 and the first direction Y is α 4, α 3 ≠ α 4.
Wherein the distance between adjacent light emitting devices 10 in the display panel 100 is different in the first stretched state and in the second stretched state. For example, the distance between adjacent light emitting devices 10 in the display panel 100 is smaller in the first stretched state and larger in the second stretched state.
In this embodiment, as shown in fig. 1, the first reflective layer group 01 and the second reflective layer group 02 are surrounded around the light-emitting device 10. In the first reflection layer group 01 and the second reflection layer group 02 surrounding the same light emitting device 10, the second reflection layer group 02 is located on a side of the first reflection layer group 01 away from the light emitting device 10. That is, the second reflective sheet 12 is farther from the light emitting device 10 with respect to the first reflective sheet 11. Since the reflective sheet is disposed around the light emitting device 10, the large-angle light emitted from the light emitting device 10 may be reflected by the reflective sheet to be emitted as the emergent light of the stretchable display panel 100, so as to increase the final emitting area of the light emitted from the light emitting device 10.
As shown in fig. 2 and 3, in the same stretching state, an included angle between the first reflective sheet 11 and the first direction Y is greater than an included angle between the second reflective sheet 12 and the first direction Y; the first direction Y is perpendicular to the plane of the light emitting device 10. That is, when the stretchable display panel 100 is in the same stretched state, the included angle between the second reflective sheet 12 farther from the light emitting device 10 and the first direction Y is smaller, that is, α 3 < α 1, α 4 < α 2.
It should be noted that the stretching will make the first reflection sheets 11 in the first reflection layer group 01 more horizontal, that is, the stretching will make the included angle between the first reflection sheets 11 in the first reflection layer group 01 and the first direction Y larger. Likewise, the stretching will make the second reflective sheets 12 in the second reflective layer group 02 more toward the horizontal state, that is, the stretching will make the included angle between the second reflective sheets 12 in the second reflective layer group 02 and the first direction Y larger.
When the stretchable display panel 100 is stretched more, the distance between the adjacent light emitting devices 10 becomes larger, and if the grain sensation of the display is to be eliminated, the light emitting area of the sub-pixel corresponding to each light emitting device 10 should be further increased. Therefore, the reflective sheet 12, which is further away from the light emitting device 10, is required to reflect the large-angle light emitted from the light emitting device 10 to increase the final emitting area of the light emitted from the light emitting device 10.
In the embodiment of the present application, if the included angle between the reflective sheet farther from the light emitting device 10 and the first direction Y is set to be smaller, the inclined angle of the farther reflective sheet can better reflect the large-angle light emitted by the light emitting device 10 when the stretchable display panel 100 is stretched to a greater extent.
Since the first reflective sheet 11 and the second reflective sheet 12 have different reflection effects on the light emitted from the light emitting device 10 due to different tilt angles, the first reflective sheet 11 and the second reflective sheet 12 may respectively play a main reflection role on the light emitted from the light emitting device 10 when the stretchable display panel 100 is in different stretching states. Therefore, when the stretchable display panel 100 is in different stretching states, the reflective sheets capable of reflecting the large-angle light emitted by the stretchable display panel 100 exist, and the problem of visual effect difference does not exist in the stretchable display panel 100 in different stretching states. The following description will be given by taking fig. 2 and 3 as examples.
When the stretchable display panel 100 is in the first stretched state as shown in fig. 2, an included angle α 1 between the first reflective sheet 11 in the first reflective layer group 01 and the first direction Y is greater than an included angle α 3 between the second reflective sheet 12 in the second reflective layer group 02 and the first direction Y. In this state, the large-angle light L1 emitted by the light emitting device 10 is reflected by the first reflective sheet 11, and thus is emitted as the emitting light of the stretchable display panel 100, increasing the final emitting area of the light emitted by the light emitting device 10, and further enabling the stretchable display panel 100 to normally display.
When the stretchable display panel 100 is in the second stretched state as shown in fig. 3, an included angle between the first reflective sheet 11, the second reflective sheet 12 and the first direction Y is larger than an included angle between the first reflective sheet 11, the second reflective sheet 12 and the first direction Y in the first stretched state, and an included angle α 2 between the first reflective sheet 11 and the first direction Y in the second stretched state is larger than an included angle α 4 between the second reflective sheet 12 and the first direction Y. In this state, the first reflective sheet 11 tends to be in a horizontal state, the reflective capability of the large-angle light L1 emitted by the light emitting device 10 is weakened, and the large-angle light L1 emitted by the light emitting device 10 is reflected by the second reflective sheet 12, so as to be emitted as the emitting light of the stretchable display panel 100, increase the final emitting area of the light emitted by the light emitting device 10, and further enable the stretchable display panel 100 to normally display.
The inventors have found, through analysis of the stretchable display panel 100 and the operation process thereof, that after the stretchable display panel 100 is stretched, the pixel pitch may increase, voids may exist between the light emitting devices 10, and voids may exist between the display units, so that the stretchable display panel 100 has a granular feeling at the pixel boundary during display, which seriously affects the display performance of the stretchable display panel 100.
Based on the above-mentioned problems and the analysis of the cause of the above-mentioned problems, in the present embodiment, the first reflection group 01 and the second reflection group 02 surrounding the light emitting device 10 are provided, and the second reflection group 02 is located on the side of the first reflection group 01 away from the light emitting device 10. The first reflection set 01 and the second reflection set 02 are respectively provided with a plurality of first reflection sheets 11 and a plurality of second reflection sheets 12, and an angle between the first reflection sheet 11 and the first direction Y is larger than an angle between the second reflection sheet 12 and the first direction Y. The large-angle light emitted by the light emitting device 10 is emitted to the region outside the light emitting device 10, and the first reflective sheet 11 in the first reflective layer group 01 and the second reflective sheet 12 in the second reflective layer group 02 can reflect the large-angle light of the stretchable display panel 100 in the first stretching state and the second stretching state respectively for display, so that the problem of increasing the gap between the light emitting devices 10 during stretching is solved, the display performance of the stretchable display panel 100 is improved, and the normal display of the stretchable display panel 100 is realized.
As shown in fig. 1 to fig. 3, the stretchable display panel 100 provided in the embodiment of the invention further includes an elastic body 14, and the elastic body 14 wraps the first reflective layer group 01 and the second reflective layer group 02.
When the elastic body 14 is stretched, the first reflective layer group 01 and the second reflective layer group 02 wrapped by the elastic body 14 are stretched, the first reflection sheet 11 in the first reflection layer group 01 and the second reflection sheet 12 in the second reflection layer group 02 are similarly stretched to change the inclination angle. It can be understood that the inclination angles of the first reflective sheet 11 and the second reflective sheet 12 are changed along with the degree of the elastic body 14 being stretched, so that when the stretchable display panel 100 is in different stretching states, there are reflective sheets capable of reflecting the light rays with large angles emitted by the light emitting device 10, and further, the stretchable display panel 100 does not have the problem of visual effect difference in different stretching states, the display performance of the stretchable display panel 100 is improved, and normal display of the stretchable display panel 100 is realized.
As shown in fig. 1 to 3, the elastic body in the stretchable display panel 100 according to the embodiment of the present invention further wraps the light emitting device 10. The elastic body 14 wraps the light emitting device 10, not only to space adjacent light emitting devices 10, but also to serve as a protective film layer of the light emitting device 10.
In the present embodiment, the elastic body 14 is disposed on the stretchable display panel 100, and the light emitting device 10, the first reflective layer group 01, and the second reflective layer group 02 are wrapped by the elastic body 14. The elastic body 14 may keep the stretchable display panel 100 in a stretched state and may also ensure that the stretchable display panel 100 is restored to its original shape when the stretched state is released. It can be understood that the elastic body 14 is arranged to wrap the light emitting device 10, the first reflective layer group 01 and the second reflective layer group 02 at the same time, so that the deformation and the distance of the light emitting device 10, the first reflective layer group 01 and the second reflective layer group 02 can be relatively consistent, and the reflective sheet in the reflective layer group can play a role in reflection, so that large-angle light emitted by the light emitting device 10 is reflected into the display unit, the condition that the display unit has a gap during stretching is improved, the display performance of the stretchable display panel 100 is improved, and normal display of the stretchable display panel 100 is realized.
The elastic body 14 may be formed of a resin, and the component of the resin used for the elastic body 14 may be an epoxy or silicone rubber.
In one embodiment of the present invention, the first reflective sheet 11 in the first reflective layer group 01 of the stretchable display panel 100 is at least one of a metal-plated foil sheet and a metal-plated copper sheet, and the second reflective sheet 12 in the second reflective layer group 02 of the stretchable display panel 100 is at least one of a metal-plated foil sheet and a metal-plated copper sheet.
In this embodiment, the reflective sheet is at least one of a metal-plated foil sheet and a metal-plated copper sheet, and the metal-plated foil sheet and the metal-plated copper sheet have a better light reflection effect. Thereby enabling more high angle light to be reflected for display.
Optionally, in an implementation manner of the embodiment of the present invention, the first reflective sheets 11 in the first reflective layer group 01 and the second reflective sheets 12 in the second reflective layer group 02 are made of the same material, and are both metal-plated foils.
Optionally, in another implementation manner of the embodiment of the present invention, the first reflective sheet 11 in the first reflective layer group 01 and the second reflective sheet 12 in the second reflective layer group 02 are made of the same material, and are both metal-plated copper sheets.
The first reflector plate 11 in the first reflector layer group 01 and the second reflector plate 12 in the second reflector layer group 02 are made of the same material, so that not only can the large-angle light emitted by the light-emitting device 10 be reflected, but also the first reflector plate 11 and the second reflector plate 12 can be simultaneously made, the implementation is easy, and the cost is saved.
As shown in fig. 1, an embodiment of the present invention provides a stretchable display panel 100, the number of first reflective sheets 11 in a first reflective layer group 01 of the stretchable display panel 100 is the same as the number of second reflective sheets 12 in a second reflective layer group 02, and an area of the first reflective sheets 11 in the first reflective layer group 01 is smaller than an area of the second reflective sheets 12 in the second reflective layer group 02.
In this embodiment, the same number of the first reflective sheets 11 and the second reflective sheets 12 are disposed on the stretchable display panel 100, and the area of the disposed first reflective sheets 11 is smaller than that of the disposed second reflective sheets 12.
In this embodiment, since the number of the first reflective sheets 11 is the same as that of the second reflective sheets 12, the display panel 100 has the same number of reflective sheets in both the first stretching state and the second stretching state to reflect the high-angle light emitted from the same light emitting device 10. It is ensured that the display panel 100 is in different stretching states, and the luminance of the sub-pixels corresponding to the light emitting devices 10 therein is substantially consistent.
Fig. 4 is a schematic plan view of a stretchable display panel according to an embodiment of the present invention.
As shown in fig. 4, an embodiment of the present invention provides a stretchable display panel 100, the number of first reflective sheets 11 in a first reflective layer group 01 of the stretchable display panel 100 is less than the number of second reflective sheets 12 in a second reflective layer group 02, and the area of the first reflective sheets 11 in the first reflective layer group 01 is the same as the area of the second reflective sheets 12 in the second reflective layer group 02.
The light emitted from the light emitting device 10 may be more lost when reaching the second reflective sheet 12 farther than when reaching the first reflective sheet 11 closer. In this embodiment, since the area of the second reflective sheet 12 is larger than the area of the first reflective sheet 11, when the display panel 100 is in the second stretching state with a larger stretching degree, the second reflective sheet with a larger area reflects the large-angle light emitted by the light emitting device 10, so that the loss when the light emitted by the light emitting device is transmitted farther can be compensated, and it is ensured that the display panel 100 is in different stretching states, and the light emitting luminances of the sub-pixels corresponding to the light emitting device 10 are substantially the same.
As shown in fig. 1 and 4, in the stretchable display panel 100 according to the embodiment of the invention, an orthographic projection of the light emitting device 10 is a circle, an orthographic projection of the first reflective layer group 01 is a first ring shape, and an orthographic projection of the second reflective layer group 02 is a second ring shape along a thickness direction of the stretchable display panel 100.
In the present embodiment, the front projection of the light emitting device 10 is set to be circular, and the front projection of the first reflective layer group 01 and the front projection of the second reflective layer group 02 are set to be a first ring shape and a second ring shape, respectively. When the stretchable display panel 100 is stretched, the light emitting device 10, the first reflective sheet 11 in the first reflective layer group 01, and the second reflective sheet 12 in the second reflective layer group 02 are rotated, and large-angle light emitted from the light emitting device 10 is rotated as the light emitting device 10 is rotated.
In this embodiment, the orthographic projection of the light emitting device 10 is circular, and the orthographic projection of the first reflective layer group 01 and the orthographic projection of the second reflective layer group 02 are respectively a first ring shape and a second ring shape. Even if the light emitting device 10, the first reflective sheet 11 in the first reflective layer group 01, and the second reflective sheet 12 in the second reflective layer group 02 have different rotation angles, the reflection effect of the first reflective sheet 11 on the large-angle light is not changed and the reflection effect of the second reflective sheet 12 on the large-angle light is not changed.
Optionally, the center of the first ring, the center of the second ring and the center of the circle of the stretchable display panel 100 coincide. That is, the center of the orthographic projection of the light emitting device 10, the center of the orthographic projection of the first reflective layer group 01, and the center of the orthographic projection of the second reflective layer group 02 coincide with each other.
As shown in fig. 1, an embodiment of the present invention provides a stretchable display panel 100, wherein, in a first reflective layer group 01 and a second reflective layer group 02 surrounding the same light emitting device 10 when the stretchable display panel 100 is in an unstretched state, a distance between the first reflective layer group 01 and the second reflective layer group 02 is d1, and d1 is 20 μm and 100 μm.
Alternatively, in the present embodiment, as shown in fig. 1, in the first reflective layer group 01 and the second reflective layer group 02 surrounding the same light emitting device 10, the distance between the first reflective layer group 01 and the second reflective layer group 02 is 50 μm.
Fig. 5 is a schematic plan view of a stretchable display panel according to an embodiment of the present invention, fig. 6 is a schematic cross-sectional structure of the stretchable display panel according to the embodiment of the present invention in a first stretched state, fig. 7 is a schematic cross-sectional structure of the stretchable display panel according to the embodiment of the present invention in a second stretched state, and fig. 8 is a schematic cross-sectional structure of the stretchable display panel according to the embodiment of the present invention in a third stretched state.
As shown in fig. 5, the stretchable display panel 100 according to the embodiment of the invention further includes a third reflective layer group 03 surrounding the light emitting device 10, and the third reflective layer group 03 is located on a light emitting surface side of a film layer on which the light emitting device 10 is located and includes a plurality of third reflective sheets 13. The third reflective layer group 03 may be configured to reflect at least a portion of light emitted from the light emitting device 10.
As shown in fig. 6 and 7, in the first stretched state, the second stretched state, and the third stretched state of the stretchable display panel 100, the inclination angle of the third reflective sheet 13 in the third reflective layer group 03 is different. For example, as shown in fig. 6 and 7, when the stretchable display panel 100 is in the first stretched state, an included angle between the third reflective sheet 13 and the first direction Y is α 5; when the stretchable display panel 100 is in the second stretched state, an included angle between the third reflective sheet 13 and the first direction Y is α 6; when the stretchable display panel 100 is in the third stretched state, an included angle between the third reflective sheet 13 and the first direction Y is α 7, α 5 ≠ α 6, α 6 ≠ α 7, and α 5 ≠ α 7.
Among them, the distance between adjacent light emitting devices 10 in the display panel 100 is different in the third stretched state and in the first stretched state, i.e., the second stretched state. For example, the distance between the adjacent light emitting devices 10 in the display panel 100 is larger in the third stretched state and smaller in the second stretched state, and the distance between the adjacent light emitting devices 10 in the display panel 100 is larger in the second stretched state and smaller in the first stretched state.
In the present embodiment, as shown in fig. 5, the first reflective layer group 01, the second reflective layer group 02, and the third reflective layer group 03 surround the light-emitting device 10. Of the first reflective layer group 01, the second reflective layer group 02, and the third reflective layer group 03 surrounding the same light-emitting device 10, the third reflective layer group 03 is located on a side of the second reflective layer group 02 away from the first reflective layer group 01. That is, the third reflection sheet 13 is farther from the light emitting device 10 than the first reflection sheet 11 and the second reflection sheet 12. Since the reflective sheet is disposed around the light emitting device 10, the large-angle light emitted from the light emitting device 10 may be reflected by the reflective sheet to be emitted as the emergent light of the stretchable display panel 100, so as to increase the final emitting area of the light emitted from the light emitting device 10.
As shown in fig. 6 and 7, in the same stretching state, an included angle between the third reflective sheet 13 in the third reflective layer group 03 and the first direction Y is smaller than an included angle between the second reflective sheet 12 in the second reflective layer group 02 and the first direction Y; the first direction Y is perpendicular to the plane of the light emitting device 10. That is, when the stretchable display panel 100 is in the same stretched state, the included angle between the third reflective sheet 13 farther from the light emitting device 10 and the first direction Y is smaller, that is, α 5 < α 3, α 6 < α 4.
Note that stretching will make the third reflective sheets 13 in the third reflective layer group 03 more toward the horizontal state, that is, stretching will make the inclination angle of the third reflective sheets 13 in the third reflective layer group 03 larger.
When the stretchable display panel 100 is changed from the second stretched state to the third stretched state, and the stretching degree thereof is increased, the distance between the adjacent light emitting devices 10 becomes larger, so that the third reflective sheet 13, which is further away from the light emitting devices 10, is required to reflect the large-angle light emitted from the light emitting devices 10, so as to further increase the final emitting area of the light emitted from the light emitting devices 10.
The following description will be given by taking fig. 6, 7, and 8 as an example.
When the stretchable display panel 100 is in the first stretched state as shown in fig. 6, an included angle α 5 between the third reflective sheet 13 in the third reflective layer group 03 and the first direction Y is smaller than an included angle α 3 between the second reflective sheet 12 in the second reflective layer group 02 and the first direction Y; an included angle α 1 between the first reflective sheet 11 in the first reflective layer group 01 and the first direction Y is greater than an included angle α 3 between the second reflective sheet 12 in the second reflective layer group 02 and the first direction Y. In this state, the large-angle light L2 emitted by the light emitting device 10 is reflected by the first reflective sheet 11, and thus is emitted as the emitting light of the stretchable display panel 100, increasing the final emitting area of the light emitted by the light emitting device 10, and further enabling the stretchable display panel 100 to normally display.
When the stretchable display panel 100 is in the second stretched state as shown in fig. 7, the included angles between the third reflective sheet 13, the second reflective sheet 12, and the first reflective sheet 11 and the first direction Y are larger than the included angles between the third reflective sheet 13, the second reflective sheet 12, and the first reflective sheet 11 and the first direction Y in the first stretched state, an included angle α 6 between the third reflective sheet 13 and the first direction Y in the second stretched state is smaller than an included angle α 4 between the second reflective sheet 12 and the first direction Y, and an included angle α 2 between the first reflective sheet 11 and the first direction Y in the second stretched state is larger than an included angle α 4 between the second reflective sheet 12 and the first direction Y. In this state, the first reflective sheet 11 tends to be in a horizontal state, the reflective capability of the large-angle light L2 emitted by the light emitting device 10 is weakened, and the large-angle light L2 emitted by the light emitting device 10 is reflected by the second reflective sheet 12, so as to be emitted as the emitting light of the stretchable display panel 100, increase the final emitting area of the light emitted by the light emitting device 10, and further enable the stretchable display panel 100 to normally display.
When the stretchable display panel 100 is in the third stretched state as shown in fig. 8, the included angles between the third reflective sheet 13, the second reflective sheet 12, and the first reflective sheet 11 and the first direction Y become larger than the included angles between the third reflective sheet 13, the second reflective sheet 12, and the first reflective sheet 11 and the first direction Y in the second stretched state, the included angle α 7 between the third reflective sheet 13 and the first direction Y in the second stretched state is smaller than the included angle between the second reflective sheet 12 and the first direction Y, and the included angle between the first reflective sheet 11 and the first direction Y in the second stretched state is larger than the included angle between the second reflective sheet 12 and the first direction Y. In this state, the first reflective sheet 11 and the second reflective sheet 12 both tend to be in a horizontal state, the reflection capability of the large-angle light L2 emitted by the light emitting device 10 is weakened, and the large-angle light L2 emitted by the light emitting device 10 is reflected by the third reflective sheet 13, so as to be emitted as the emitted light of the stretchable display panel 100, increase the final emitting area of the light emitted by the light emitting device 10, and further enable the stretchable display panel 100 to normally display.
In this embodiment, a first reflection group 01, a second reflection group 02, and a third reflection layer group 03 surrounding the same light emitting device 10 are provided, and the third reflection layer group 03 is located on a side of the second reflection layer group 02 away from the first reflection layer group 01. A plurality of third reflective sheets 13 are disposed in the third reflective layer group 03, and an included angle between each of the third reflective sheets 13 and the first direction Y is smaller than an included angle between each of the first reflective sheet 11 and the second reflective sheet 12 and the first direction Y. When the stretchable display panel 100 is stretched to a greater extent, the first reflective sheet 11 in the first reflective layer group 01 and the second reflective sheet 12 in the second reflective layer group 02 tend to be in a horizontal state, the reflective capability of the light emitting device 10 to emit high-angle light is weakened, and the high-angle light emitted by the light emitting device 10 is reflected by the third reflective sheet 13 in the third reflective layer group 03 for display, so that the problem that the gap between the light emitting devices 10 is increased during stretching is solved, the display performance of the stretchable display panel 100 is improved, and normal display of the stretchable display panel 100 is realized.
As shown in fig. 6 to 8, in the same stretching state, the difference between the angles between the third reflective sheet 13 and the second reflective sheet 12 and the first direction Y is smaller than the difference between the angles between the second reflective sheet 12 and the first reflective sheet 11 and the first direction Y. That is, (α 1-. Alpha.3) > (α 3-. Alpha.5), (α 2-. Alpha.4) > (α 4-. Alpha.6). For example, as shown in fig. 6 to 8, the farther the reflective sheet is from the light emitting device 10, the greater the tendency of the reflective sheet to stand upright. That is, when the stretchable display panel 100 is in the same stretched state, the inclination angle of the third reflective sheet 13 farther from the light emitting device 10 is smaller, and when the stretchable display panel 100 is stretched more, the inclination angle of the farther reflective sheet can better reflect the large-angle light emitted by the light emitting device 10. Thereby improving the visual effect problem in the stretching process, improving the display performance of the stretchable display panel 100, and realizing the normal display of the stretchable display panel 100.
Fig. 9 is a schematic diagram of a stretchable display device according to an embodiment of the present invention.

It can be understood that the stretchable display device provided in the embodiment of the present invention may be a display device with a display function, such as a computer, a television, a vehicle, a wearable device, an artificial intelligence device, and the present invention is not limited in this respect.
The stretchable display device provided by the embodiment of the invention establishes a split reflection scheme by arranging a multi-turn reflection layer group around the light emitting device 10 and arranging a plurality of reflection sheets in the reflection layer group. When the stretchable display device is in different stretching states, large-angle light emitted by the light emitting device 10 can be reflected by the reflectors in different reflecting layer groups and then used for displaying, the visual effect problem of the display device in the stretching process is solved, the display performance of the stretchable display device is improved, and normal display of the stretchable display device is realized.
