[0027] Example 1

[0028] FIG. 2 is a top view schematic diagram showing a plurality of pixel cells in a non-stretched state in a first display area according to a first embodiment of the present application. FIG. 3 is a top view schematic diagram showing a plurality of pixel cells in a stretched state in a first display area according to a first embodiment of the present application. As shown in FIG. 1 to FIG. 3, in a first aspect, a first embodiment of the present application provides an extensible display panel, which includes a plurality of pixel cells 100 and a plurality of extensible bridges 200, and each of the extensible bridges 200 is connected to two adjacent pixel cells 100. Here, a periphery 101 of the pixel cell 100 includes at least one first edge 102 and a second edge 103 other than the at least one first edge 102, and the pixel cell 100 is connected to the extensible bridge 200 at the first edge 102. The extensible display panel further includes an anti-deformation layer 300 disposed around at least a portion of the first edge 102 .

[0029] The extensible display panel provided in the present application includes an extensible state and a non-extensible state, when the extensible display panel is in an extensible state, the extensible bridge 200 is in an extensible state, and the extensible bridge 200 connected to the pixel cell 100 applies stress to the pixel cell 100, and the extensible display panel further includes an anti-deformation layer 300, which supports the edge 101 of the pixel cell 100, and thus has the function of preventing the shape of the edge 101 of the pixel cell 100 from changing, thereby improving the problem of the shape of the edge 101 of the pixel cell 100 changing due to the extensible bridge 200 applying stress to the pixel cell 100, and thus improving the display effect of the extensible display panel and increasing the reliability of the extensible display panel.

[0030] In some embodiments of the present application, the deformation prevention layer 300 has a first elastic modulus and the extensible bridge 200 has a second elastic modulus, where the first elastic modulus is greater than the second elastic modulus.

[0031] In the extensible display panel provided by the present application, since the first elastic modulus is greater than the second elastic modulus, the deformation prevention function of the anti-deformation layer 300 is greater than the deformation prevention function of the extensible bridge 200, thereby further improving the supporting function of the anti-deformation layer 300 for the edge 101 of the pixel cell 100, solving the problem of deformation of the pixel cell 100 in an extensible state, further improving the display effect of the extensible display panel, and increasing the reliability of the display panel.

[0032] In some embodiments of the present application, the material of the deformation prevention layer 300 is a metal material.

[0033] The stretchable display panel provided by the present application can reduce the parasitic capacitance between the pixel cells 100 due to the excellent anti-deformation function of the metal material, thereby improving the display effect of the stretchable display panel.

[0034] In some embodiments of the present application, the material of the deformation prevention layer 300 is an insulating material.

[0035] In the stretchable display panel provided by the present application, the stretchable display panel has a non-stretched state, and in the non-stretched state, the stretchable bridge 200 can be in a meandering state, which may reduce the distance between the stretchable bridge 200 and the anti-deformation layer 300, even cause contact, and even cause a short circuit. The present application makes the material of the anti-deformation layer 300 an insulating material, thereby improving the stability of use of the stretchable display panel and extending its lifespan.

[0036] In some embodiments of the present application, the pixel cell 100 has a third modulus of elasticity, the first modulus of elasticity being greater than the third modulus of elasticity, and the third modulus of elasticity being greater than the second modulus of elasticity.

[0037] In the stretchable display panel provided by the present application, since the third elastic modulus is greater than the second elastic modulus, the deformation prevention function of the pixel cell 100 is greater than the deformation prevention function of the stretchable bridge 200, thereby further improving the problem of deformation of the pixel cell 100 in a stretched state, further improving the display effect of the display panel, and further enhancing the reliability of the display panel.

[0038] In some embodiments of the present application, when in a non-stretched state, the shape of the periphery 101 of the pixel cell 100 is rectangular, wherein the second edge 103 includes four edge corners 1031, and wherein the anti-deformation layer 300 surrounds the four edge corners 1031.

[0039] In the extensible display panel provided by the present application, the four rectangular corners 1031 play an important role in defining the shape of the edge 101 of the pixel cell 100. Therefore, the present application avoids the first edge 102 from the four rectangular corners 1031 and has the anti-deformation layer 300 surround the four rectangular corners 1031, thereby further strengthening the support function of the anti-deformation layer 300 for the edge 101 of the pixel cell 100, improving the problem of deformation of the pixel cell 100 in an extended state, further improving the display effect of the display panel, and further increasing the reliability of the extensible display panel.

[0040] In some embodiments of the present application, when in a non-stretched state, Four corners 1031 home of One edge corner 1031 is adjacent to the pixel cell 100. Four corners 1031 home of It is disposed opposite one edge corner portion 1031 .

[0041] In the stretchable display panel provided by the present application, the first edge 102 is disposed on the side of the rectangle so as to avoid the four edge corners 1031 of the rectangle. Four corners 1031 home ofOne edge corner 1031 is adjacent to the pixel cell 100. Four corners 1031 home of Since the extensible bridge 200 is disposed opposite one edge corner 1031, compared to a structure in which the sides of two adjacent pixel cells 100 are disposed opposite each other, the structure in which the corners of two adjacent pixel cells 100 are disposed opposite each other can extend the distance between both ends of the extensible bridge 200 at the same pixel density, thereby improving the maximum extensible length of the extensible display panel and improving the extensible characteristics of the extensible display panel.

[0042] In some embodiments of the present application, when in the stretched state, Four corners 1031 home of One edge corner 1031 is adjacent to the pixel cell 100. Four corners 1031 home of It is disposed opposite one edge corner portion 1031 .

[0043] Continuing to refer to FIG. 2, when in a non-stretched state, the extensible bridge 200 connecting two adjacent pixel cells 100 in a first direction X is in a bent state, and the extensible bridge 200 connecting two adjacent pixel cells 100 in a second direction Y is in a bent state, the maximum spacing between the pixel cells 100 in the first direction X is a, and the maximum spacing between the pixel cells 100 in the second direction Y is b.

[0044] Continuing with reference to FIG. 3, when the extensible display panel is stretched in a second direction Y, the extensible bridges 200 connecting two adjacent pixel cells 100 in the first direction X are in a bent state, and the extensible bridges 200 connecting two adjacent pixel cells 100 in the second direction Y are in a flat (or nearly flat) state, and the maximum spacing of the pixel cells 100 in the first direction X is a1, and the maximum spacing of the pixel cells 100 in the second direction Y is b1, where a1 is equal to a, b1 is equal to b, and c1 is greater than c.

[0045] That is, when the extensible display panel is in an extensible state, the distance between two adjacent pixel cells 100 in the extensible direction becomes larger, but the shape and area of ​​the pixel cells 100 do not change due to the restrictive effect of the deformation prevention layer, that is, the shape of the pixel cell 100 in the extensible state is the same as the shape of the pixel cell 100 in the non-extensible state. The area of ​​the pixel cell 100 in the extensible state is the same as the area of ​​the pixel cell 100 in the non-extensible state. This can improve the display effect of the extensible display panel and increase the reliability of the display panel.

[0046] In some embodiments of the present application, the display panel includes a display area 10 and a non-display area 20, and the non-display area 20 surrounds the display area 10. Here, the display area 10 includes a first display area 11 and a second display area 12, and a plurality of pixel cells 100 are arranged in both the first display area 11 and the second display area 12, and the second display area 12 surrounds the first display area 11, and a periphery 101 of each pixel cell 100 in the first display area 11 includes four first edges 102.

[0047] In the extensible display panel provided by the present application, a plurality of pixel cells 100 are also arranged in the second display area 12, and the second display area 12 surrounds the first display area 11, so that other pixel cells 100 are also arranged around the pixel cell 100 at the extreme end of the periphery 101 of the first display area 11. In the prior art, the extension direction of the extensible display panel includes at least two directions, a first direction X and a second direction Y, i.e., each pixel cell 100 in the first display area 11 needs to be connected with at least four other pixel cells 100, and therefore each pixel cell 100 in the first display area 11 needs to include at least four first edges 102. In the present application, the periphery 101 of each pixel cell 100 in the first display region 11 includes four first edges 102, thereby minimizing the number of the first edges 102 in the first display region 11, thereby maximizing the periphery 101 of each pixel cell 100 other than the first edges 102, thereby providing more space for the installation of the deformation prevention layer 300, further strengthening the support function of the deformation prevention layer 300 for the periphery 101 of the pixel cell 100, improving the problem of deformation of the pixel cell 100 in an extended state, further improving the display effect of the display panel, and further increasing the reliability of the stretchable display panel.

[0048] In some embodiments of the present application, in the pixel cell 100 in the first display area 11, the two first edges 102 are Square The first edge 102 is located on one side of the first edge 102. Square The deformation prevention layer 300 is located on the other side. Square Enclose the other two sides.

[0049] In the stretchable display panel provided by the present application, the deformation prevention layer 300 not only surrounds the four edge corners 1031 of the rectangle, but also SquareSince it also surrounds the other two sides, the installation area of ​​the anti-deformation layer 300 can be increased, the support function of the anti-deformation layer 300 for the edge 101 of the pixel cell 100 is further strengthened, the problem of deformation of the pixel cell 100 in an elongated state is alleviated, the display effect of the display panel is further improved, and the reliability of the stretchable display panel is further increased.

[0050] In addition, in the non-stretched state, the shape of the pixel cell 100 may be other than a rectangle, for example, a circle or a polygon other than a rectangle. In the non-stretched state, when the shape of the pixel cell 100 is a circle, the deformation prevention layer 300 may be disposed around all of the periphery 101 of the pixel cell 100 other than the first edge 102. In the non-stretched state, when the shape of the pixel cell 100 is a polygon other than a rectangle, the deformation prevention layer 300 is disposed around all of the edge corners 1031 of the polygon.

[0051] The shape of the periphery 101 of the deformation prevention layer 300 may be arc-shaped or linear.

[0052] In a second aspect, Example 1 of the present application further provides a display device, the display device including a housing and any one of the above-mentioned extensible display panels, wherein the housing has an accommodation space, the extensible display panel is disposed in the accommodation space, and the housing is extensible.

[0053] Example 2

[0054] FIG. 4 is a top view schematic diagram showing a plurality of pixel cells in a non-stretched state in a first display area according to a second embodiment of the present application. FIG. 5 is a top view schematic diagram showing a plurality of pixel cells in a stretched state in a first display area according to a second embodiment of the present application. As shown in FIG. 1, FIG. 4 and FIG. 5, in a first aspect, the second embodiment of the present application provides an extensible display panel, which includes a plurality of pixel cells 100 and a plurality of extensible bridges 200, and each of the extensible bridges 200 is connected to two adjacently arranged pixel cells 100. Here, a periphery 101 of the pixel cell 100 includes at least one first edge 102 and a second edge 103 other than the at least one first edge 102, and the pixel cell 100 is connected to the extensible bridge 200 at the first edge 102. The extensible display panel further includes an anti-deformation layer 300 disposed around at least a portion of the first edge 102 .

[0055] In addition, the structure of the stretchable display panel provided in the second embodiment of the present application is similar to the structure of the stretchable display panel provided in the first embodiment of the present application, for example, in a non-stretched state, the shape of the periphery 101 of the pixel cell 100 is a rectangle, the second edge 103 includes four edge corners 1031, and the deformation prevention layer 300 surrounds the four edge corners 1031. Four corners 1031 home of One edge corner 1031 is adjacent to the pixel cell 100. Four corners 1031 home of When in the extended state, the pixel cell 100 is disposed opposite one of the edge corners 1031. Four corners 1031 home of One edge corner 1031 is adjacent to the pixel cell 100. Four corners 1031 home of It is disposed so as to face one edge corner 1031. In the second embodiment of the present application, the description of the same parts will be omitted.

[0056] The difference is that the display panel includes a display area 10, which includes a first display area 11 and a second display area 12, both of which have a plurality of pixel cells 100 arranged therein, and the second display area 12 surrounds the first display area 11, where a periphery 101 of each pixel cell 100 in the first display area 11 includes eight first edges 102.

[0057] In the stretchable display panel provided by the present application, the periphery 101 of each pixel cell 100 in the first display area 11 includes eight first edges 102, and the more the number of first edges 102, the more the number of the stretchable bridges 200, thereby improving the stretchable feel of the stretchable display panel and enhancing the user experience.

[0058] In some embodiments of the present application, in the pixel cell 100 in the first display area 11, two of the first edges 102 are disposed on each of the sides of the quadrilateral.

[0059] In the extensible display panel provided by the present application, two first edges 102 are arranged on each side of the rectangle, so that the positions of the first edges 102 on the periphery 101 of the pixel cells 100 are set more regularly, and thus the arrangement manner of the extensible bridges 200 is more regular, so that the extensible display panel in the stretched state has more uniform stretch amounts in different regions, which is advantageous to improving the display quality of the extensible display panel in the stretched state.

[0060] In some embodiments of the present application, two of the first edges 102 are disposed on either side of each edge corner 1031 .

[0061] Continuing to refer to FIG. 4, when in a non-extended state, the extensible bridge 200 connecting two adjacent pixel cells 100 in a first direction X is in a bent state, and the extensible bridge 200 connecting two adjacent pixel cells 100 in a second direction Y is in a bent state, the maximum spacing between the pixel cells 100 in the first direction X is a, and the maximum spacing between the pixel cells 100 in the second direction Y is b.

[0062] Continuing with reference to FIG. 5, when the extensible display panel is stretched in a second direction Y, the extensible bridges 200 connecting two adjacent pixel cells 100 in the first direction X are in a bent state, and the extensible bridges 200 connecting two adjacent pixel cells 100 in the second direction Y are in a flat (or nearly flat) state, and the maximum spacing of the pixel cells 100 in the first direction X is a1, and the maximum spacing of the pixel cells 100 in the second direction Y is b1, where a1 is equal to a, b1 is equal to b, and c1 is greater than c.

[0063] That is, when the extensible display panel is in an extensible state, the spacing between two adjacent pixel cells 100 in the extensible direction becomes larger, but the shape and area of ​​the pixel cells 100 do not change due to the limiting effect of the anti-deformation layer, thereby improving the display effect of the extensible display panel and enhancing the reliability of the display panel.

[0064] In a second aspect, Example 2 of the present application further provides a display device, the display device including a housing and any one of the above-mentioned extensible display panels, wherein the housing has an accommodation space, the extensible display panel is disposed in the accommodation space, and the housing is extensible.

Here, a periphery 101 of the pixel cell 100 includes at least one first edge 102 and a second edge 103 other than the at least one first edge 102, and the pixel cell 100 is connected to the extensible bridge 200 at the first edge 102. The extensible display panel further includes an anti-deformation layer 300 disposed around at least a portion of the first edge 102 .

[0067] It should be noted that the structure of the extensible display panel provided in Example 3 of the present application is similar to that of the extensible display panel provided in Example 1 of the present application, for example, in a non-extensible state, the shape of the periphery 101 of the pixel cell 100 is a rectangle, the four edge corners 1031 of the rectangle are the periphery 101 other than the first edge 102, and the deformation prevention layer 300 surrounds the four edge corners 1031 of the rectangle. In Example 3 of the present application, the description of the same parts will be omitted.

[0068] The difference is that when in a non-stretched state, Four sides home of One side of the pixel cell 100 is adjacent to another pixel cell 100. Four sides home of It is placed opposite one side.

[0069] In the extensible display panel provided by the present application, any one of the pixel cells 100 Four sides home of One side of the pixel cell 100 is adjacent to another pixel cell 100. Four sides home ofSince the pixel cells 100 are arranged opposite one side, they can have an array arrangement manner in which they are arranged in a matrix, which is advantageous in improving the manufacturing efficiency of the extensible display panel and reducing production costs.

Here, the display area 10 includes a first display area 11 and a second display area 12, and a plurality of pixel cells 100 are arranged in both the first display area 11 and the second display area 12, and the second display area 12 surrounds the first display area 11, and a periphery 101 of each pixel cell 100 in the first display area 11 includes four first edges 102.

[0072] In the extensible display panel provided by the present application, a plurality of pixel cells 100 are also arranged in the second display area 12, and the second display area 12 surrounds the first display area 11, so that other pixel cells 100 are also arranged around the pixel cell 100 at the extreme end of the periphery 101 of the first display area 11. In the prior art, the extension direction of the extensible display panel includes at least two directions, a first direction X and a second direction Y, i.e., each pixel cell 100 in the first display area 11 needs to be connected with at least four other pixel cells 100, and therefore each pixel cell 100 in the first display area 11 needs to include at least four first edges 102. In the present application, the periphery 101 of each pixel cell 100 in the first display region 11 includes four first edges 102, thereby minimizing the number of the first edges 102 in the first display region 11, thereby maximizing the periphery 101 of each pixel cell 100 other than the first edges 102, thereby providing more space for the installation of the deformation prevention layer 300, further strengthening the support function of the deformation prevention layer 300 for the periphery 101 of the pixel cell 100, improving the problem of deformation of the pixel cell 100 in an extended state, further improving the display effect of the display panel, and further increasing the reliability of the stretchable display panel.

[0073] In some embodiments of the present application, in the pixel cell 100 in the first display area 11, one of the first edges 102 is disposed on each of the sides of the rectangle.

[0074] In the extensible display panel provided by the present application, two first edges 102 are arranged on each side of the rectangle, so that the positions of the first edges 102 on the periphery 101 of the pixel cells 100 are set more regularly, and thus the arrangement manner of the extensible bridges 200 is more regular, so that the extensible display panel in the stretched state has more uniform stretch amounts in different regions, which is advantageous to improving the display quality of the extensible display panel in the stretched state.

[0075] Continuing to refer to FIG. 6, when in a non-extended state, the extensible bridge 200 connecting two adjacent pixel cells 100 in a first direction X is in a bent state, and the extensible bridge 200 connecting two adjacent pixel cells 100 in a second direction Y is in a bent state, the maximum spacing between the pixel cells 100 in the first direction X is a, and the maximum spacing between the pixel cells 100 in the second direction Y is b.

[0076] Continuing with reference to FIG. 7, when the extensible display panel is stretched in a second direction Y, the extensible bridges 200 connecting two adjacent pixel cells 100 in the first direction X are in a bent state, and the extensible bridges 200 connecting two adjacent pixel cells 100 in the second direction Y are in a flat (or nearly flat) state, and the maximum spacing of the pixel cells 100 in the first direction X is a1, and the maximum spacing of the pixel cells 100 in the second direction Y is b1, where a1 is equal to a, b1 is equal to b, and c1 is greater than c.

[0077] That is, when the extensible display panel is in an extensible state, the spacing between two adjacent pixel cells 100 in the extensible direction becomes larger, but the shape and area of ​​the pixel cells 100 do not change due to the limiting effect of the anti-deformation layer, thereby improving the display effect of the extensible display panel and enhancing the reliability of the display panel.

[0078] In a second aspect, Example 3 of the present application further provides a display device, the display device including a housing and any one of the above-mentioned extensible display panels, wherein the housing has an accommodation space, the extensible display panel is disposed in the accommodation space, and the housing is extensible.

The extensible display panel further includes an anti-deformation layer 300 disposed around at least a portion of the first edge 102 .

[0081] In addition, the structure of the extensible display panel provided by the fourth embodiment of the present application is similar to the structure of the extensible display panel provided by the third embodiment of the present application.

Four sides home of One side of the pixel cell 100 is adjacent to another pixel cell 100. Four sides home of In the fourth embodiment of the present invention, the description of the same parts will be omitted.

[0082] The difference is that the display panel includes a display area 10, which includes a first display area 11 and a second display area 12, both of which have a plurality of pixel cells 100 arranged therein, and the second display area 12 surrounds the first display area 11, where a periphery 101 of each pixel cell 100 in the first display area 11 includes eight first edges 102.

[0083] In the stretchable display panel provided by the present application, the periphery 101 of each pixel cell 100 in the first display area 11 includes eight first edges 102, and the more the number of first edges 102, the more the number of the stretchable bridges 200, thereby improving the stretchable feel of the stretchable display panel and enhancing the user experience.

[0084] In some embodiments of the present application, in the pixel cell 100 in the first display area 11, two of the first edges 102 are disposed on each of the sides of the quadrilateral.

[0085] In the extensible display panel provided by the present application, two first edges 102 are arranged on each side of the rectangle, so that the positions of the first edges 102 on the periphery 101 of the pixel cells 100 are set more regularly, and thus the arrangement manner of the extensible bridges 200 is more regular, so that the extensible display panel in the stretched state has more uniform stretch amounts in different regions, which is advantageous to improving the display quality of the extensible display panel in the stretched state.

[0086] In some embodiments of the present application, two of the first edges 102 are disposed on either side of each edge corner 1031 .

[0089] That is, when the extensible display panel is in an extensible state, the spacing between two adjacent pixel cells 100 in the extensible direction becomes larger, but the shape and area of ​​the pixel cells 100 do not change due to the limiting effect of the anti-deformation layer, thereby improving the display effect of the extensible display panel and enhancing the reliability of the display panel.
