Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly to a display module and a display device. Background Technology

[0002] With the rapid development of display devices, foldable displays have gradually become popular. In existing foldable displays, a support plate is set on one side of the display panel to ensure that the surface of the foldable display panel does not deform. However, the support plate in the existing technology leaves obvious bending marks when bent, and is prone to bending fatigue in the bendable area, leading to breakage of the support plate. Summary of the Invention

[0003] This invention provides a display module and display device that improve the flexibility of the support plate during bending and enhance the bending performance of the support plate.

[0004] In a first aspect, embodiments of the present invention provide a display module, the display module including a bendable area and a non-bendable area;

[0005] The display module further includes a display panel and a support plate, wherein the support plate is located on the non-light-emitting side of the display panel;

[0006] The support plate includes a base and at least one set of support structures;

[0007] The support structure group is embedded in the matrix, and the support structure group includes multiple support structures;

[0008] The extension direction of the support structure intersects with the first direction, and the material of the support structure includes a reversible material; the first direction is the extension direction of the bendable region.

[0009] Secondly, embodiments of the present invention also provide a display device, including any of the display modules described in the first aspect.

[0010] The display module provided by this invention includes a bending area and a non-bending area. The display module also includes a display panel and a support plate, with the support plate located on the non-light-emitting side of the display panel. The support plate includes a substrate and at least one set of support structures. The support structure sets are embedded in the substrate and include multiple support structures. The extending direction of the support structures intersects with a first direction, and the material of the support structures includes a reversible material. The first direction is the extending direction of the bending area. Thus, when the support plate is bent, the support structures embedded in the substrate deform.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this invention. Obviously, the described embodiments are only some embodiments of this invention, not all embodiments. Based on the basic concepts disclosed and indicated in the embodiments of this invention, all other embodiments obtained by those skilled in the art are within the scope of protection of this invention.

[0028] Figure 1 This is a schematic diagram of the structure of a display module provided in an embodiment of the present invention. Figure 2 yes Figure 1 A simplified diagram of a cross-sectional structure along the A-A' direction. Figure 3 yes Figure 1 A simplified cross-sectional diagram along the B-B' direction. See also... Figures 1-3 The display module includes a bendable area AA and a non-bendable area AB. The display module also includes a display panel 10 and a support plate 20, with the support plate 20 located on the non-light-emitting side of the display panel 10. The support plate 20 includes a substrate 210 and at least one set of support structure groups 220. The support structure groups 220 are embedded within the substrate 210 and include multiple support structures 221. The extending direction of the support structures 221 intersects a first direction X, and the material of the support structures 221 includes a reversible material. The first direction X is the extending direction of the bendable area AA.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the display module can be a foldable display module, including a bendable area AA and a non-bendable area AB, wherein the non-bendable area AB can be located on both sides of the bendable area AA. In the flattened state, both the bendable area AA and the non-bendable area AB are flat and located on the same horizontal plane. At this time, the radii of curvature of both the non-bendable area AB and the bendable area AA are infinite, and their radii of curvature are equal. In the bent state, the bendable area AA bends around the bending axis a, and the non-bendable areas AB located on both sides of the bendable area AA can achieve the folding of the display module through the bending axis a. At this time, the non-bendable area AB is flat, and its radius of curvature is still infinite. The bendable area AA bends around the bending axis a at a certain angle, and its radius of curvature is the bending radius of the bendable area AA. Furthermore, the radius of curvature of the non-bendable area AB is greater than the radius of curvature of the bendable area AA.

[0030] It is understood that, in order to illustrate the bending center of the bending region AA, the bending axis a is introduced in this embodiment of the invention. Those skilled in the art will readily realize that in actual products, the bending axis a is not a solid structure, and the bending axes of different film layers in the bending region AA may have a certain degree of offset. Therefore, the bending axis a mentioned in this embodiment of the invention represents a virtual approximate range.

[0031] The display module also includes a display panel 10 and a support plate 20. Exemplarily, the display panel 10 may include an array substrate, a light-emitting layer, an encapsulation layer, and a touch layer (not shown in the above figures) stacked sequentially. This embodiment of the invention does not limit the specific type of the display panel 10; for example, the display panel may be a liquid crystal display panel, an organic light-emitting display panel, or a Mini-LED, etc. Exemplarily, the array substrate may include a driving circuit, the light-emitting layer may include multiple light-emitting elements, and the driving circuit is electrically connected to the light-emitting elements to drive them to emit light. The specific configuration of the driving circuit may differ depending on the driving method of the light-emitting elements. Specifically, when the driving method of the light-emitting elements is active driving, the driving circuit may include multiple thin-film transistors to drive the light-emitting elements to emit light; when the driving method of the light-emitting elements is passive driving, the driving circuit may include cathode signal lines and anode signal lines to provide the light-emitting elements with the cathode and anode signals required for light emission, thereby driving the light-emitting elements to emit light and realizing the display of the display panel 10. The support plate 20 is located on the non-light-emitting side of the display panel 10 and is used to support the display panel 10. When the display module is bent, the support plate 20 supports the bending of the display panel 10, therefore the support plate 20 needs to have good bending performance. In the prior art, the support plate is usually made of steel as the support material. When the steel support plate is bent, the bending marks in the bendable area are more obvious, and bending fatigue is prone to occur during repeated bending, leading to the breakage of the support plate.

[0032] Therefore, in this embodiment of the invention, at least one set of support structure groups 220 is embedded in the base 210 of the support plate 20, and the support structure group 220 includes a plurality of support structures 221. For example, as shown... Figure 3 In the illustrated embodiment, multiple support structures 221 can be located on the same plane, and the plane containing the multiple support structures 221 can be parallel to the plane containing the support plate 20 in its flattened state. In other embodiments, for example, multiple support structures 221 can be located on the same plane, and the plane containing the multiple support structures 221 can intersect the plane containing the support plate 20 in its flattened state, or multiple support structures 221 can be located on different planes. The material of the support structure 221 includes a reversible material. The reversible material has reversibility; when the support structure 221 is bent and deformed, it will recover its original shape under external environmental stimulation. Since the extension direction of the support structure 221 intersects with the first direction X, and the first direction X is the extension direction of the bendable region AA, when the support plate 20 is bent and the support structure 221 is deformed, under external environmental stimulation, the support structure 221 whose extension direction intersects with the first direction X will recover its original shape, thus providing support for the support plate 20. The support structure 221 provides a tensile force opposite to the bending direction. Under external environmental stimuli, although the support structure 221 will recover its original shape, the tensile force provided by the support structure 221 is relatively small, preventing it from fully returning to its original shape. This means the support plate 20 remains bent, thus improving the flexibility of the support plate 20 during bending, minimizing bending marks, and reducing the risk of bending fatigue and breakage during repeated bending, thereby improving the bending performance of the support plate 20. For example, the support structure 221 can include thermotropic reversible materials, phototropic reversible materials, or magnetotropic reversible materials, etc. Specifically, when the support structure 221 includes a thermotropic reversible material, the support structure 221 bends with the support plate 20 and recovers its original shape after the external temperature reaches a set temperature, providing the support plate 20 with a tensile force opposite to the bending direction; when the support structure 221 includes a phototropic reversible material, the support structure 221 bends with the support plate 20 and recovers its original shape under light conditions, providing the support plate 20 with a tensile force opposite to the bending direction; when the support structure 221 includes a magnetotropic reversible material, the support structure 221 bends with the support plate 20 and recovers its original shape under magnetic conditions, providing the support plate 20 with a tensile force opposite to the bending direction, and so on. This invention does not limit the specific reversible material of the support structure 221; those skilled in the art can set it as needed.

[0033] It should be noted that, Figure 2 and Figure 3The example given is an example of the original shape of the support structure 221 being a long strip, but this is not a limitation. In other embodiments, the support structure 221 can also be other shapes, and those skilled in the art can set them as needed.

[0034] Understandable Figure 1 The illustration uses only an example where the bendable area AA is located in the middle area of ​​the display module. In other embodiments, Figure 4 This is a schematic diagram of the structure of a display module provided in an embodiment of the present invention, as shown below. Figure 4 As shown, the bendable area AA can also be located in the diagonal area of ​​the display module. The embodiments of the present invention do not limit the specific location of the bendable area AA, and those skilled in the art can set it as needed.

[0035] In summary, this embodiment of the invention embeds at least one set of support structures within the substrate of a support plate. Each support structure set includes multiple support structures, the extension direction of which intersects with a first direction, which is the extension direction of the bendable region. The support structures include a reversible material with reversible properties. When the support plate is bent, causing deformation of the embedded support structures, under external environmental stimuli, the support structures whose extension direction intersects with the extension direction of the bendable region will recover their original shape, providing the support plate with a tensile force opposite to the bending direction. Because the tensile force provided by the support structures is relatively small, the support structures will not return to their original shape; that is, the support plate remains in a bent state. This improves the flexibility of the support plate during bending, reduces the bending marks on the support plate, and enhances the bending performance of the support plate.

[0036] Optional, see below Figures 1-3 Within the same support structure group 220, multiple support structures 221 extend in the same direction and are evenly spaced along the first direction X. For example, as shown... Figure 1 and Figure 2 In the illustrated embodiment, a set of support structure groups 220 is embedded within the substrate 210. Multiple support structures 221 within the support structure group 220 extend in the same direction, and all of these directions intersect with the first direction X. That is, the angle between the extension direction of each support structure 221 and the first direction X is the same, thus ensuring that each support structure 221 provides the same tensile force to the support plate 20. Furthermore, the multiple support structures 220 are evenly spaced along the first direction X, resulting in a uniform distribution of the tensile force provided by the support structure group 220 to the support plate 20 along the first direction X. This makes the stress on the support plate 20 more uniform in the first direction X, further improving the bending performance of the support plate 20.

[0037] Optional, Figure 5 yes Figure 1 A simplified cross-sectional diagram along the C-C' direction. See also... Figure 1 , Figure 3 and Figure 5 The support structure 221 includes a first support structure portion 221a located in the bendable region AA and a second support structure portion 221b located in the non-bending region AB. The cross-sectional area of ​​the first support structure portion 221a is equal to the cross-sectional area of ​​the second support structure portion 221b. Specifically, after cutting along the plane containing the first direction X and the thickness direction of the support plate 20, the exposed area of ​​the support structure 221 is the cross-sectional area of ​​the support structure 221. Since the cross-sectional area of ​​the first support structure portion 221a is equal to the cross-sectional area of ​​the second support structure portion 221b, the portion of the support structure 221 located in the bendable region AA and the portion located in the non-bending region AB have the same shape and size. In other words, the tensile force provided by the support structure 221 to the support plate 20 in the bendable region AA and the non-bending region AB is evenly distributed, making the force on the support plate 20 more uniform in the extension direction of the support structure 221, thus further improving the bending performance of the support plate 20.

[0038] Optional, Figure 6 This is a schematic diagram of another display module provided in an embodiment of the present invention. Figure 7 yes Figure 6 A simplified diagram of a cross-sectional structure along the D-D' direction. Figure 8 yes Figure 6 A simplified cross-sectional diagram along the E-E' direction is shown below. Figure 6 , Figure 7 and Figure 8 The support structure 221 includes a first support structure portion 221a located in the bendable region AA and a second support structure portion 221b located in the non-bendable region AB. The cross-sectional area of ​​the first support structure portion 221a is smaller than the cross-sectional area of ​​the second support structure portion 221b.

[0039] Specifically, after cutting along the plane containing the first direction X and the thickness direction of the support plate 20, the exposed area of ​​the support structure 221 is the cross-sectional area of ​​the support structure 221. Considering that when the display module returns from a bent state to a flat state, a larger force needs to be applied to the non-bent area AB of the display module to make the non-bent area AB drive the bendable area AA to return to flatness, the cross-sectional area of ​​the first support structure portion 221a can be set to be smaller than the cross-sectional area of ​​the second support structure portion 221b. That is, the cross-sectional area of ​​the support structure 221 located in the bendable area AA is smaller than the cross-sectional area of ​​the support structure 221 located in the non-bent area AB. The larger the cross-sectional area of ​​the support structure 221, the greater the tensile force provided by the support structure 221. Consequently, the tensile force provided by the support structure 221 for the non-bent area AB is greater than the tensile force provided for the bendable area AA. In this way, the recovery speed of the display module from a bent state to a flat state is improved, enhancing the user experience.

[0040] For example, based on the above embodiments, see below. Figure 7 and Figure 8 Along the arrangement direction of the plurality of support structures 221, the width of the first support structure portion 221a is less than the width of the second support structure portion 221b, and / or, along the thickness direction of the support plate 20, the thickness of the first support structure portion 221a is less than the thickness of the second support structure portion 221b.

[0041] Specifically, the cross-sectional area of ​​the support structure 221 is the product of the width of the support structure 221 along the arrangement direction of the plurality of support structures 221 and the thickness of the support structure 221 along the thickness direction of the support plate 20. This can be achieved by setting the width of the first support structure portion 221a to be smaller than the width of the second support structure portion 221b along the arrangement direction of the plurality of support structures 221, thus making the cross-sectional area of ​​the first support structure portion 221a smaller than the cross-sectional area of ​​the second support structure portion 221b; or by setting the thickness of the first support structure portion 221a to be smaller than the thickness of the second support structure portion 221b along the thickness direction of the support plate 20, thus making the cross-sectional area of ​​the first support structure portion 221a smaller than the cross-sectional area of ​​the second support structure portion 221b. The area is smaller than the cross-sectional area of ​​the second support structure portion 221b; or by setting the width of the first support structure portion 221a to be smaller than the width of the second support structure portion 221b along the arrangement direction of the multiple support structures 221, and the thickness of the first support structure portion 221a to be smaller than the thickness of the second support structure portion 221b along the thickness direction of the support plate 20, so that the cross-sectional area of ​​the first support structure portion 221a is smaller than the cross-sectional area of ​​the second support structure portion 221b, thereby making the tension provided by the support structure 221 for the non-bending area AB greater than the tension provided for the bendable area AA, improving the recovery speed of the display module from a bent state to a flat state, and improving the user experience.

[0042] Optional, Figure 9 This is a schematic diagram of another display module provided in an embodiment of the present invention. Figure 10 yes Figure 9 A simplified diagram of a cross-sectional structure along the F-F' direction. (Example) Figure 9 and Figure 10 As shown, the support plate 20 also includes a buffer structure assembly 230. The buffer structure assembly 230 is embedded in the substrate 210 and located on at least one side of the support structure assembly 220. The buffer structure assembly 230 includes a plurality of buffer structures 231, the elastic modulus of which is greater than that of the substrate 210.

[0043] Specifically, the support plate 20 also includes a buffer structure assembly 230, which is embedded within the base 210. The buffer structure assembly 230 includes multiple buffer structures 231. For example, Figure 10 In the illustrated embodiment, multiple buffer structures 231 may be located on the same plane, and the plane containing the multiple buffer structures 231 may be parallel to the plane containing the support plate 20 in its flattened state. In other embodiments, for example, multiple buffer structures 231 may be located on the same plane, and the plane containing the multiple buffer structures 231 may intersect with the plane containing the support plate 20 in its flattened state, or multiple buffer structures 231 may be located on different planes. The buffer structure group 230 is located on at least one side of the support structure group 220. For example, when the support plate 20 includes a group of support structure groups 220, the buffer structure group 230 may be located on the side of the support structure group 220 away from the display panel 10. Thus, when the support plate 20 is subjected to an impact force, the buffer structure group 230 is closer to the impacted location and can better absorb the impact force. The elastic modulus of the buffer structure 231 is greater than the elastic modulus of the substrate 210. For example, the material of the substrate 210 can be a mixed resin, thereby reducing the overall weight of the support plate 20. Furthermore, by setting the elastic modulus of the buffer structure 231 to be greater than that of the substrate 210, on the one hand, the buffer structure 231 with a larger elastic modulus is less prone to deformation when the support plate 20 is subjected to impact, thus improving the impact resistance of the support plate 20. On the other hand, the larger elastic modulus of the buffer structure 231, i.e., the greater stiffness of the buffer structure 231, can enhance the overall strength of the support plate 20 and improve its support effect on the display panel 10.

[0044] Based on the above embodiments, see below. Figure 9 Multiple buffer structures 231 are arranged in an array along the first direction X and the second direction Y. The second direction Y is the direction from the bendable region AA to the non-bendable region AB.

[0045] Specifically, multiple buffer structures 231 are arranged in an array along the first direction X and the second direction Y. That is, in the flattened state, multiple buffer structures 231 are evenly arranged on the plane where the support plate 20 is located, so that the impact resistance effect at each position on the impact-resistant surface of the support plate 20 is similar, further improving the impact resistance performance of the support plate 20.

[0046] Figure 11 This is a schematic diagram of another display module provided in an embodiment of the present invention. See also... Figure 11 The arrangement density of multiple buffer structures 231 in the bendable region AA is less than the arrangement density of multiple buffer structures 231 in the non-bendable region AB.

[0047] Specifically, such as Figure 11 As shown, in this embodiment of the invention, when the display module is bent, the non-bending area AB bends around the bending axis a, that is, the non-bending area AB remains flat, while the bendable area AA bends. Therefore, it is necessary to ensure that the bending performance of the part of the support plate 20 located in the bendable area AA is good. Since the elastic modulus of the buffer structure 231 is greater than that of the substrate 210, when the support plate 20 corresponding to the bendable area AA is provided with more buffer structures 231, the interval between adjacent buffer structures 231 in the bendable area AA will be smaller, and the buffer structures 231 with greater stiffness will squeeze each other, making it difficult for the support plate 20 to bend in the bending area AA. Furthermore, by setting the arrangement density of multiple buffer structures 231 in the bendable area AA to be less than that in the non-bendable area AB, the spacing between adjacent buffer structures 231 in the bendable area AA of the support plate 20 is larger. Consequently, when the bendable area AA is bent, adjacent buffer structures 231 are less likely to come into contact, or the compressive force between buffer structures 231 is smaller, making the support plate 20 easier to bend. This improves the bending performance of the support plate 20 in the bendable area AA while ensuring the overall strength of the support plate 20.

[0048] Figure 12 This is a schematic diagram of another display module provided in an embodiment of the present invention. See also... Figure 12 Along the second direction Y, the arrangement density of multiple buffer structures 231 gradually decreases. The second direction Y is the direction from the bendable area AA to the non-bendable area AB.

[0049] Specifically, to ensure good bending performance of the support plate 20 located in the bendable area AA, the density of the multiple buffer structures 231 can be gradually reduced along the direction from the bendable area AA to the non-bending area AB. Because of the greater degree of bending, adjacent buffer structures 231 in this area are more likely to come into contact, or in other words, the compressive force after contact is greater. Conversely, because of the smaller degree of bending, adjacent buffer structures 231 in this area are less likely to come into contact, or in other words, the compressive force after contact is smaller. Therefore, by setting the spacing between adjacent buffer structures 231 to be the largest in the area with the greatest degree of bending and the smallest in the area with the least degree of bending, the bending performance of the support plate 20 can have a gradual effect. That is, the bending performance is best in the area with the greatest degree of bending, and the support effect is best in the area with the least degree of bending, thus improving the user experience.

[0050] Optionally, based on the above embodiments, the buffer structure 231 includes a buffer rubber ball. Specifically, since the spherical surface in the spherical structure is arched in all directions, when pressure is applied to any position of the spherical structure, the pressure can be evenly distributed to the surrounding spherical surface, thereby withstanding greater pressure. Thus, by setting the buffer structure 231 to include a buffer rubber ball, the impact resistance of the support plate 20 can be further improved.

[0051] Figure 13 yes Figure 9 Another schematic diagram of the cross section along F-F'. See also Figure 9 and Figure 13 The support plate 20 includes at least two sets of support structure groups 220. Multiple support structures 231 in the same support structure group 220 extend in the same direction, and multiple support structures in different support structure groups 220 extend in the same direction.

[0052] Specifically, the support plate 20 includes at least two sets of support structure groups 220, which are spaced apart along the thickness direction of the support plate 20. When the support plate 20 is bent, causing the embedded support structure 221 to deform, under the stimulation of the external environment, the at least two sets of support structure groups 220 along the thickness direction of the support plate 20 provide a tensile force opposite to the bending direction to the support plate 20, further improving the flexibility of the support plate 20 during bending and improving the bending performance of the support plate. In addition, the extension directions of multiple support structures 231 in the same support structure group 220 are the same, and the extension directions all intersect with the first direction X, that is, the angle between the extension direction of each support structure 221 and the first direction X is the same. Consequently, the tensile force provided by each support structure 221 in the same support structure group 220 to the support plate 20 is the same, so that the tensile force provided by multiple support structures 220 to the support plate 20 is evenly distributed in the plane of the support plate 20. The extension directions of multiple support structures in different support structure groups 220 are the same, that is, in the thickness direction of support plate 20, the tension provided by different support structure groups 220 is the same, which makes the force on support plate 20 more uniform in the thickness direction of support plate 20, and further improves the bending performance of support plate 20.

[0053] Based on the above embodiments, see below. Figure 13 The support plate 20 also includes a buffer structure assembly 230, which is embedded in the substrate 210. At least two sets of support structure assemblies 220 are located on the side of the buffer structure assembly 230 closer to the display panel 10.

[0054] Specifically, at least two sets of support structure groups 220 are located on the side of the buffer structure group 230 closer to the display panel 10, that is, the buffer structure group 230 is located on the side of the at least two sets of support structure groups 220 away from the display panel 10. When the support plate 20 is subjected to impact force, the buffer structure group 230 is closer to the impacted position and can better absorb the impact force, further improving the impact resistance of the support plate 20.

[0055] Figure 14 Yes, yes Figure 9 See another schematic diagram of the cross section along F-F'. Figure 14 The support plate 20 also includes a buffer structure assembly 230, which is embedded within the substrate 210. At least two sets of support structure assemblies 220 include a first support structure assembly 2201 and a second support structure assembly 2202. The first support structure assembly 2201 is located on the side of the buffer structure assembly 230 closer to the display panel 10, and the second support structure assembly 2202 is located on the side of the buffer structure assembly 230 away from the display panel 10.

[0056] Specifically, at least two sets of support structure groups 220 are arranged at intervals along the thickness direction of the support plate 20, and the first support structure group 2201 and the second support structure group 2202 are located on both sides of the buffer structure group 230, respectively. When the support plate 20 is bent and the embedded support structure 221 is deformed, under external stimulation, the support structure group 220 on different sides of the buffer structure group 230 along the thickness direction of the support plate 20 provides a tensile force opposite to the bending direction, thereby making the support plate 20 with the buffer structure group 230 easier to bend. While ensuring the impact resistance and overall strength of the support plate 20, the bending performance of the support plate 20 is improved.

[0057] Optionally, based on the above embodiments, see also... Figure 1 The angle between the extension direction of the support structure 221 and the first direction X is α, where α satisfies: 30° ≤ α ≤ 150°. Specifically, when the extension direction of the support structure 221 intersects the first direction X, the support structure 221 can provide a tensile force opposite to the bending direction to the support plate 20 as it recovers its original shape. However, when the extension direction of the support structure 221 is parallel to the first direction X, the bending of the support plate 20 cannot cause the support structure 221 to deform, and therefore, under external stimuli, the support structure 221 cannot provide a tensile force to the support plate 20. Therefore, the angle between the extension direction of the support structure 221 and the first direction X cannot be 0° or 180°. Furthermore, considering that if the angle between the extension direction of the support structure 221 and the first direction X is too small or too large, the tensile force provided by the support structure group 220 in the opposite direction of bending will be too small and insufficient to improve the flexibility of the support plate 20. Therefore, by setting the angle α between the extension direction of the support structure 221 and the first direction X to satisfy: 30°≤α≤150°, the support structure group 220 provides a larger tensile force in the opposite direction of bending to the support plate 20 when restoring its original shape, ensuring that the flexibility of the support plate 20 during bending is improved, reducing the bending marks of the support plate 20, and improving the bending performance of the support plate 20.

[0058] It should be noted that when the extension direction of the support structure 221 is perpendicular to the first direction X, i.e., α = 90°, the support structure group 220 provides the maximum tension to the support plate 20 when restoring its original shape.
