In the related art foldable display device, a supporting plate is generally disposed on the opposite side of the display side of the flexible display module, and a plurality of hollow patterns (Pattern) are disposed in a bending region of the supporting plate to meet the bending performance of the foldable display device. However, since the arrangement of the hollow patterns in the odd-numbered rows is the same as the arrangement of the hollow patterns in the even-numbered rows is the same as the arrangement of the hollow patterns in the odd-numbered rows is different from the arrangement of the hollow patterns in the even-numbered rows, the m-th (m is a positive integer) linking part which starts from the odd-numbered rows (located between two hollow patterns in the same row) is located on the same straight line, and the m-th (m is a positive integer) linking part which starts from the even-numbered rows is also located on the same straight line. During the bending process, the bending stress will be gathered on the straight line and cannot be released, thereby generating a film print. In the related art, the film printing is covered by increasing the thickness of the glue on the surface of the hollow pattern of the bending region or covering a layer of support plate without the hollow pattern on the surface of the support plate with the hollow pattern, but both schemes increase the weight of the folding display device and cannot meet the development trend of pursuing lightness and thinness.
In order to solve the above technical problems in the related art, an embodiment of the present disclosure provides a supporting plate (e.g., a stainless steel plate, SUS) for supporting a flexible display module, as shown in fig. 1 to 5, the supporting plate includes a bending area BA, the bending area BA includes a plurality of hollow patterns 101 arranged in an array, a joint portion 102 is provided between two adjacent hollow patterns 101 in a same row, and at least the joint portions 102 in three adjacent rows are staggered in a column direction Y.
In the above-mentioned backup pad that this disclosed embodiment provided, through improving the mode of arranging of fretwork pattern 101 for linking portion 102 in at least adjacent triplex staggers the setting in row direction Y, thereby has reduced linking portion 102 and has lain in the probability on the collinear, does benefit to the evenly distributed of bending stress from this, can effectively solve the die mark problem. Moreover, the thickness of the glue in the related technology does not need to be increased or a supporting plate is additionally arranged, so that the weight of the product is not increased, and the light and thin design is favorably realized.
In some embodiments, in the above-mentioned support plate provided in the embodiments of the present disclosure, as shown in fig. 3 to 5, the bending area BA may further include: and a groove 103, wherein the groove 103 is positioned at least part of the row gap G of the hollow pattern 101. The existence of the groove 103 provides a dispersion channel for the bending stress at the joint portion 102, thereby preventing the bending stress from being excessively concentrated at the joint portion 102, and thus, the stamping problem can be effectively solved. In addition, it should be understood that the thickness h of the support plate at the groove 103, as shown in fig. 4 and 5 1 Is less than the thickness h of the support plate outside the groove 103 and the hollowed-out pattern 101 2 Therefore, the arrangement of the groove 103 can reduce the overall weight of the support plate, and the development trend of light and thin is met. Optionally, the depth h of the recess 103 3 The thickness h of the support plate outside the groove 103 and the hollowed-out pattern 101 can be less than or equal to 2 Half of the thickness h of the support plate in the recess 103 1 The thickness h of the support plate outside the groove 103 and the hollow pattern 101 is more than or equal to 2 And thus the modulus of the support plate can be ensured while effectively dispersing bending stress. Alternatively, as shown in fig. 3, 6, 7 and 10, the groove 103 may penetrate through the bending area BA in the row direction X, or, as shown in fig. 8 and 9, the groove 103 may not penetrate through the bending area BA in the row direction X, and is not particularly limited herein.
In some embodiments, in the support plate provided in the embodiments of the present disclosure, as shown in fig. 6 to 10, each adjacent three rows of the hollow patterns 101 are in one group, and the groove 103 is located at a group gap G' of the hollow patterns 101. Since the connecting portions 102 in at least three rows are arranged in a staggered manner in the column direction Y, the area of at least three rows does not generate a die mark due to bending stress, and therefore, the grooves 103 can be arranged at the group gap G' of every adjacent three rows of the hollow patterns 101, so that the bending stress is further dispersed, and the risk of generating the die mark is reduced. In addition, even though the joint portions 102 in the remaining rows except the three rows are located on the same straight line, the bending stress at the joint portions 102 in every adjacent three rows can be effectively diffused to the adjacent grooves 103 at two sides, so that the distribution of the bending stress is more uniform, and the probability of occurrence of stamping is further reduced. Certainly, in specific implementation, the number of rows of the hollow patterns 101 in each group is not limited to one group of three adjacent rows of the hollow patterns 101, and may also be flexibly set according to actual needs.
In some embodiments, in the above-described support plate provided by the embodiments of the present disclosure, as shown in fig. 3, 6, and 7, all the engaging portions 102 are arranged in a staggered manner in the column direction Y, so that the engaging portions 102 are uniformly distributed in the bending area BA, thereby achieving more uniform distribution of bending stress.

In fig. 8 to 10, each adjacent 5 rows of the hollow patterns 101 are in a cycle period, and the connecting portions 102 in the same cycle period are arranged in a staggered manner in the column direction Y. Since the respective joint portions 102 are arranged in a staggered manner in the column direction Y in the same cycle period, the bending stress can be uniformly distributed in the same cycle period. And the hollow patterns 101 in more than 3 adjacent rows are arranged as a cycle period, so that enough space can be provided for buffering the bending stress, and the distribution of the bending stress is more uniform.
In some embodiments, in the above-described support plate provided by the embodiments of the present disclosure, as shown in fig. 8 to 10, the length L of the engaging portion 102 in the row direction X is 1 The same, and the lengths L of the hollow patterns 101 between any two adjacent linking parts 102 in the same row in the row direction X 2 The same to facilitate the staggered arrangement of the engagement portions 102. Alternatively, as shown in fig. 11, it is also possible to set the length L in the row direction X of the adjacent joint portion 102 in the column direction Y 1 Different from and between any two adjacent connection parts 102 in the same rowThe length L of the hollow pattern 101 in the row direction X 2 In contrast, the offset arrangement of the engagement portions 102 is realized.
Note that, in fig. 3, 6 to 11, only a partial enlarged view of the bending area BA is schematically shown, and therefore, only one engaging portion 102 is shown in one row, and in an actual product, there may be a plurality of engaging portions 102 arranged in a staggered manner in each row of the bending area BA.
In some embodiments, in the support plate provided in the embodiments of the present disclosure, as shown in fig. 3, 6 to 11, the hollow pattern 101 includes an end portion 1011, the end portion 1011 is disposed in contact with the connecting portion 102, and a contact surface of the end portion 1011 and the connecting portion 102 is an arc surface. The cambered surface is more favorable for dispersing bending stress, and avoids stamping caused by the concentration of the bending stress. The length L of the joint portion 102 in the row direction X 1 Can be defined as the distance between the two ends 1011 that contact the joint 102 in the row direction X.
In some embodiments, in the support plate provided in the embodiments of the present disclosure, as shown in fig. 3, 6 to 11, the end portions 1011 at two sides of the same connecting portion 102 have the same shape, which not only facilitates the making of the hollow pattern 101, but also is beneficial to ensuring the uniform distribution of the bending stress at two sides of the connecting portion 102. Alternatively, as shown in fig. 3, 9 to 11, all the end portions 1011 may be provided in the same shape; alternatively, as shown in fig. 6 to 8, the odd-numbered line ends 1011 may have the same shape, the even-numbered line ends 1011 may have the same shape, and the odd-numbered line ends 1011 may have a shape different from the shape of the even-numbered line ends 1011. Through the combination of the end 1011 of the above shape, the modulus of the support plate can be effectively adjusted to meet different bending requirements.
In some embodiments, in the support plate provided in the embodiments of the present disclosure, as shown in fig. 12 to 14, the modulus of the support plate may also be adjusted by providing different shapes of the end portions 1011 on both sides of the same engagement portion 102. Optionally, in a specific implementation, the modulus of the supporting plate may also be adjusted by adjusting the length and density of the hollow pattern 101, which is not limited herein.

In some embodiments, in the support plate provided in the embodiments of the present disclosure, as shown in fig. 3, 6 to 14, the shape of the end 1011 may be a water drop shape, a U shape, a capsule shape, or the like, which is convenient to manufacture and can effectively adjust the modulus of the support plate. Of course, in practical implementation, the shape of the end 1011 may be other shapes known to those skilled in the art, and is not limited herein.
In some embodiments, in the support plate provided by the embodiments of the present disclosure, as shown in fig. 3, 6 to 14, the edge F of the bending area BA extending along the column direction Y is not continuously disposed. Specifically, the edge F of the bending area BA extending along the column direction Y is disposed at the hollow pattern 101 in a broken manner, and is disposed continuously at the row gap G of the hollow pattern 101, so that the edge F of the bending area BA extending along the column direction Y is disposed discontinuously. The discontinuous edge F of the bending area BA increases the elasticity of the bending area BA, and is beneficial to improving the rebound resilience and the flatness of the unfolding of the bending area BA.
In some embodiments, in the support plate provided in the embodiments of the present disclosure, as shown in fig. 3, 6 to 14, an extending direction (corresponding to the row direction X) of the hollow pattern 101 is parallel to the bending axis S of the bending area BA, so that the support plate is easy to bend when folded and can quickly return to a flat state when unfolded.
In some embodiments, in the support plate provided in the embodiments of the present disclosure, as shown in fig. 1 and 2, the support plate may further include a non-bending region UBA, where the non-bending region UBA is located on both sides of the bending region BA parallel to the bending axis S, so that the folding performance of the support plate is satisfied through the bending region BA, and the non-bending region UBA may not be provided with the hollow pattern 101 and the groove 103, so that the support performance of the support plate is satisfied through the non-bending region UBA. In some embodiments, in order to meet the weight reduction requirement and achieve light weight, a blind hole may also be disposed in the unbending region UBA. Alternatively, the areas of the two non-bending areas UBA may be the same, i.e. the bending area BA is located in the central area of the support plate.

Specifically, an embodiment of the present disclosure provides a display device, as shown in fig. 15, including: backup pad 001 and flexible display module 002, backup pad 001 is above-mentioned backup pad 001 that this disclosed embodiment provided, and backup pad 001 laminates in the opposite side of the demonstration side of flexible display module 002. Optionally, the supporting plate 001 is attached to the opposite side of the display side of the flexible display module 002 through an adhesive layer 003. The whole face setting of bondline 003 can be carried out, optionally, in order to make the preparation technology of bondline 003 simpler, and guarantee that the planarization of bondline 003 is better, also can only set up bondline 003 at non-bending region UBA, do not set up bondline 003 at bending region BA promptly, because backup pad 001 is the stereoplasm, only laminate backup pad 001 at non-bending region UBA and flexible display module 002, backup pad 001 still can play better supporting role to flexible display module 002 at bending region BA.
In addition, in the assembling process of the supporting plate 001 and the flexible display module 002, there is a possibility that a large assembling deviation occurs, and at this time, in order to reduce the rejection rate, the supporting plate 001 needs to be removed and then reassembled with the flexible display module 002. Based on this, the adhesive layer 003 may be selected from uv-curable adhesive, double-sided adhesive, pressure-sensitive adhesive, hot melt adhesive, or the like. When the bonding layer 003 is an ultraviolet-reduced adhesive, the ultraviolet-reduced adhesive can be irradiated by ultraviolet light to reduce the viscosity of the ultraviolet-reduced adhesive so as to remove the support plate 001. When the adhesive layer 003 is a double-sided tape, the support plate 001 can be directly peeled off, and the support plate 001 can be easily removed. When the adhesive layer 003 is a pressure-sensitive adhesive, the tackiness of the pressure-sensitive adhesive can be reduced by changing the pressure so as to remove the support plate 001. When the adhesive layer 003 is a hot melt adhesive, the viscosity of the hot melt adhesive can be reduced by heating so that the support plate 001 can be removed.
