[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of the present application provides a display component, including:

[0037] The carrying assembly 1 is configured to carry the flexible display module 3 and drive the flexible display module 3 to bend or fold;

[0038] At least two support layers 2 are stacked in sequence on the bearing assembly 1, each support layer 2 is bendable and has a resilient property, and each support layer 2 has a hollow pattern; the hollow patterns of the support layers 2 are different in at least one of the following properties: the area of ​​the hollow portion 20, the shape of the hollow portion 20, and the position of the hollow portion 20;

[0039] The flexible display module 3 is located on a side of the at least two supporting layers 2 facing away from the bearing assembly 1 .

[0040] In the display assembly provided in the embodiment of the present application, a whole layer of support layer 2 is used as the screen support structure between the bearing assembly 1 and the flexible display module 3, which can achieve good bending performance in the bending or folding hinge area and provide good flatness when the screen is unfolded. It is a flexible screen support solution with good performance and yield. In addition, compared with only setting a single support layer 2, at least two layers of support layers 2 are developed in a three-dimensional direction, that is, the support for the flexible screen can be improved by multi-layer stacking, and the bending and support can be flexibly adjusted by different settings of the hollow parts 20 of each support layer 2, further effectively improving the bending performance and support performance of the support as a whole, thereby achieving a more excellent screen support technical effect and solving the demand for the screen module support structure of the curved and folding terminal display product.

[0041] In some embodiments, each support layer 2 is a stainless steel material layer (SUS). The stainless steel material layer (SUS) is bendable and has a rebound property, and has good properties such as high hardness, good toughness, high temperature resistance and corrosion resistance, and is a good material for the flexible screen support layer 2.

[0042] In some embodiments, Figure 1 , Figure 2 and Figure 4 As shown, the display component is a folding display component, wherein the supporting component 1 includes a first middle frame 11 and a second middle frame 12, and a hinge component 13 located between the first middle frame 11 and the second middle frame 12, and the first middle frame 11 and the second middle frame 12 can be rotated around the hinge component 13 respectively to achieve folding or unfolding, so as to drive the flexible display module 3 to fold.

[0043] Of course, the display component may also be a bendable component or a rollable component to drive the flexible display module 3 to bend or roll.

[0044] Exemplarily, the at least two supporting layers 2 may include two supporting layers 2 ; or, the at least two supporting layers 2 may include three or four layers, and of course may also include more supporting layers 2 .

[0045] Exemplarily, the thickness of each support layer 2 is 0.01 mm-0.15 mm.

[0046] Specifically, the thickness of each support layer 2 and the number of support layers 2 can be selected according to factors such as the thickness requirement for actual support and the processing technology level of the support layer 2.

[0047] In some embodiments, the hollow pattern of each supporting layer 2 includes at least one hollow area, and the hollow area includes a plurality of hollow portions 20 distributed in an array.

[0048] Exemplarily, the hollow area of ​​the support layer 2 is a region consisting of hollow portions 20 distributed in an array, for example, Figure 6 and Figure 7 The area formed by the hollow parts 20 included in each dotted frame is a hollow area 200; specifically, the hollow area 200 can be set at the position where the support layer 2 needs to be bent or folded, and the number and location of the hollow area 200 can correspond to the number and location of the bending area of ​​the flexible display module. Figure 6 As shown, the flexible display module is a foldable display device having a bending portion, and the support layer 2 can be provided with a hollow area 200 at the position of the bending portion; or Figure 7 As shown, the flexible display module has three bending parts, and the support layer 2 can be provided with three hollow areas 200 at the positions of the three bending parts. Of course, the hollow parts 20 can also be provided on the entire area (bending area and non-bending area) of the support layer 2, for example Figure 1 , Figure 2 and Figure 4 As shown in FIG. 1 , at this time, the hollow portions 20 on the entire area of ​​the support layer 2 form a hollow area.

[0049] Specifically, the array-distributed hollow portions 20 can ensure the overall support performance of each support layer 2, and make each support layer 2 have better flexibility and improve its bending and folding performance. In addition, the pattern of the array-distributed hollow portions 20 is relatively simple, easy to process and manufacture, and low in cost.

[0050] For example, the hollow portions 20 in each support layer 2 may have the same shape, specifically, a strip shape, such as Figure 3 and Figure 5 The hollow portion 20 shown in the figure, the extending direction of the strip is consistent with the bending or folding axis direction of the flexible display module; that is, the hollow portion 20 in each supporting layer 2 is a strip hollow portion 20, and the extending direction of the strip hollow portion 20 is consistent with the bending or folding axis direction of the flexible display module. Specifically, "the direction is consistent" includes both complete parallelism and a certain error. For example, the angle between the extending directions of the two is less than a certain angle, for example, the angle is less than 10 degrees.

[0051] Take the folding display component as an example. Figure 1 , Figure 2 and Figure 4As shown, the first middle frame 11 and the second middle frame 12 rotate around the shaft assembly 13 to drive the flexible display module 3 to fold or unfold, and the axis direction of the bending or folding of the flexible display module 3 is the direction parallel to the shaft in the shaft assembly 13. Alternatively, when the display assembly is a rollable assembly, the axis direction is the direction parallel to the scroll axis.

[0052] Specifically, the extension direction of the hollow portion is consistent with the axis direction of the bending or folding, which can effectively improve the bending and folding performance of the support layer, thereby improving the overall bending yield and effect of the display component.

[0053] In some embodiments, the areas of the hollow portions 20 in the support layers 2 are different.

[0054] For example, Figure 3 As shown in (a) and (b), the hollow portion 20 of each supporting layer 2 is a strip-shaped hollow portion 20 whose extension direction is consistent with the axial direction of the bending or folding, and the strip-shaped hollow portion 20 of each supporting layer 2 has the same width C, different lengths A, and thus different areas.

[0055] Of course, the widths C of the strip-shaped hollow portions 20 of the support layers 2 may be different, and the lengths A may be the same or different, for example. Figure 1 and Figure 2 As shown in , the area of ​​the hollow portion 20 is different.

[0056] Specifically, the larger the area of ​​the hollow portion 20 of each hollow region 200 in the support layer 2 is, the better its bending performance is. Furthermore, the area of ​​the hollow portion 20 of each support layer 2 can be designed according to the requirements of the bending performance of each support layer 2.

[0057] For example, Figure 1 and Figure 2 As shown, the area of ​​the hollow portion 20 of each support layer 2 increases in sequence from the inner side to the outer side of the flexible display module 3 when it is bent or folded. Specifically, the "inner side" refers to the side of the surface hidden inside after bending or folding; the "outer side" refers to the side of the surface exposed outside after bending or folding.

[0058] For example, Figures 1 to 3 As shown, the hollow portions 20 in each supporting layer 2 correspond to each other, and the orthographic projections of the corresponding hollow portions 20 on the flexible display module 3 at least partially overlap; that is, the distribution positions of the hollow portions 20 in each supporting layer 2 are the same.

[0059] For example, the centers of the orthographic projections of the corresponding hollow portions 20 in each supporting layer 2 on the flexible display module 3 coincide with each other. Alternatively, at least part of the boundaries of the corresponding hollow portions 20 in each supporting layer 2 may be aligned.

[0060] For example, taking the strip-shaped hollow portion as an example, Figure 3 As shown in (a) and (b), the strip-shaped hollow portions 20 of each supporting layer 2 have the same width C and different lengths A, and the two boundaries of the corresponding hollow portions in each supporting layer 2 are aligned in the width C direction, and the midpoints are aligned in the length A direction. Of course, the length A and width C of the strip-shaped hollow portions 20 of each supporting layer 2 may be different, in which case the midpoints of the corresponding hollow portions 20 in each supporting layer 2 are aligned in the length A and width C directions.

[0061] For example, Figure 1 and Figure 2 As shown, the orthographic projection of the hollow portion 20 of the supporting layer 2 close to the inner side of the bend or fold on the flexible display module 3 is located within the orthographic projection of the hollow portion 20 of the supporting layer 2 close to the outer side of the bend or fold on the flexible display module 3.

[0062] Specifically, when the display assembly is bent or folded, Figure 1 and Figure 2 As shown, the flexible display module 3 and the support layer 2 are bent or folded as the bearing assembly 1 is bent or folded. Among the support layers 2, the support layer 2 near the outer side where the bending or folding occurs has a larger tensile deformation and a greater demand for tensile performance, while the support layer 2 near the inner side where the bending or folding occurs has a lower demand for tensile performance. In the implementation of the present application, the support layer 2 near the outer side where the bending or folding occurs has a relatively larger hollow portion 20 area, and the support layer 2 near the inner side where the bending or folding occurs has a relatively smaller hollow portion 20 area, which can improve the bending performance of the support layer 2 and provide good support for the flexible display module 3 when the screen is unfolded.

[0063] Take the foldable display assembly as an example, for example, the foldable display assembly includes two support layers 2. Specifically:

[0064] like Figure 1 As shown, in the inward folded form, the flexible display module 3 and each supporting layer 2 are located between the first middle frame 11 and the second middle frame 12 of the supporting component 1; among the two layers of supporting layers 2, the supporting layer 2 close to the supporting component 1 is located on the outside of the fold, and its tensile performance requirements are greater. The supporting layer 2 has a larger hollow portion 20, and the supporting layer 2 close to the flexible display module 3 is located on the inside of the fold, and its bending requirements are relatively lower. The supporting layer 2 has a smaller hollow portion 20, which mainly provides support when the screen is unfolded.

[0065] like Figure 2As shown, when in the outward folded form, the flexible display module 3 and each supporting layer 2 are sequentially wrapped around the outside of the first middle frame 11 and the second middle frame 12; among the two layers of supporting layers 2, the supporting layer 2 close to the flexible display module 3 is located on the outside of the fold, and its tensile performance requirements are greater. The supporting layer 2 has a larger hollow portion 20, and the supporting layer 2 close to the supporting component 1 is located on the inside of the fold, and its bending requirements are relatively lower. The supporting layer 2 has a smaller hollow portion 20, which mainly provides support when the screen is unfolded.

[0066] Further, taking a foldable mobile phone as an example, its display assembly includes two support layers 2, such as Figure 3 As shown in (a) and (b) in the figure, the hollowed-out portion 20 of each support layer 2 is in the shape of a strip that extends in the same direction as the folding axis, with the direction of the strip hollowed-out portion 20 extending as the row direction, and the hollowed-out portions 20 in adjacent rows are staggered. Specifically, the length A of the hollowed-out portion 20 can be in the range of 1mm-10mm, the width C of the hollowed-out portion 20 can be in the range of 0.1mm-1mm, the spacing B between adjacent hollowed-out portions 20 along the length direction of the hollowed-out portion 20 can be 0.1mm-10mm, and the spacing D between adjacent rows of hollowed-out portions 20 along the width direction of the hollowed-out portion 20 can be 0.1mm-1mm. For example, the patterns of the hollowed-out portions 20 of the two layers of support layers 2 can be as follows: Figure 3 As shown in (a) and (b) in FIG. Figure 3 As shown in (a), the length A of the hollow portion 20 in a support layer 2 is 4.3 mm, and the spacing B between adjacent hollow portions 20 along the length direction of the hollow portion 20 is 1.1 mm; Figure 3 As shown in (b), the length A of the hollow portion 20 in the other supporting layer 2 is 5.3 mm, and the spacing B between adjacent hollow portions 20 along the length direction of the hollow portion 20 is 0.1 mm; the width C of the hollow portions 20 of the two supporting layers 2 and the spacing D between adjacent rows of hollow portions 20 along the width direction are equal. Specifically, the width C of the hollow portion 20 can be 0.2 mm, and the spacing D between adjacent hollow portions 20 along the width direction can be 0.1 mm.

[0067] In other embodiments, Figure 5 As shown in (a) and (b), the hollow area of ​​each supporting layer 2 includes a plurality of hollow portions 20 distributed in an array, but the distribution positions of the hollow portions 20 of each supporting layer 2 are different.

[0068] For example, Figure 4 As shown, the hollow portions 20 of each support layer 2 are staggered in orthographic projection on the flexible display module 3. That is, the hollow portions 20 in each support layer 2 are staggered and stacked without overlapping each other.

[0069] For example, the patterns of the hollow portions 20 in each supporting layer 2 may be designed to be complementary.

[0070] Specifically, the hollow parts of each supporting layer are arranged in an alternating manner, and the patterns of the hollow parts have a complementary effect. This scheme can be applied to both inward-folding and outward-folding display components. The complementary pattern design can solve the defect of insufficient support of a single-layer supporting layer, and at the same time can improve the overall bending performance of each supporting layer.

[0071] For example, Figure 5 As shown in (a) and (b) of the figure, the hollow portions 20 of each support layer 2 have the same shape and area. For example, the hollow portions 20 of each support layer 2 are all strip-shaped hollow portions 20 whose extension direction is consistent with the axis direction of the bending or folding, and the length A and width C of the strip-shaped hollow portions 20 of each support layer 2 are equal. Of course, in other embodiments, the shapes and / or areas of the hollow portions 20 of each support layer 2 may also be different.

[0072] Specifically, the hollow portions 20 of each supporting layer 2 have the same shape and area, which can ensure good complementarity between the supporting layers 2 and facilitate unified processing and manufacturing of the supporting layers 2, thereby reducing costs.

[0073] Specifically, taking a foldable mobile phone as an example, its display assembly includes two support layers 2, such as Figure 5 As shown in (a) and (b), the hollow portions 20 of the two support layers 2 have the same shape and area, but the two hollow portions 20 are arranged alternately; the hollow portions 20 of each support layer 2 are in the shape of strips in the same extension direction as the folding axis, and the hollow portions 20 of adjacent rows are arranged alternately with the extension direction of the strip hollow portions 20 as the row direction. Specifically, the length A of the hollow portions 20 can be in the range of 1mm-10mm, the width C of the hollow portions 20 can be in the range of 0.1mm-1mm, the spacing B between adjacent hollow portions 20 along the length direction of the hollow portions 20 can be 1mm-10mm, and the spacing D between adjacent rows of hollow portions 20 along the width direction of the hollow portions 20 can be 0.1mm-1mm. For example, in each supporting layer 2, the length A of the hollow portion 20 is 2.3 mm, the spacing B between adjacent hollow portions 20 along the length direction of the hollow portion 20 is 3.1 mm, the width C of the hollow portion 20 is 0.2 mm, and the spacing D between adjacent rows of hollow portions 20 along the width direction is 0.1 mm.

[0074] In some embodiments, the shapes of the hollow portions 20 in each support layer 2 may also be different; the shape of the hollow portions 20 may include a strip shape (such as Figure 3 and Figure 5 ), rectangle (as shown in Figure 6 and Figure 7 ), diamond (as shown in Figure 8 as shown in ), elliptical (as shown in Fig. 9 At least one of the shapes shown in ).

[0075] Specifically, the shape of the above-mentioned hollow portion has an extension direction, for example, the extension direction of the long side of a strip or rectangle, the extension direction of the longer diagonal of a rhombus, and the long axis direction of an ellipse; the hollow portions of these shapes are similar to the arrangement of the strip-shaped hollow portions in the above-mentioned embodiments, and their extension directions are consistent with the extension direction of the rotating shaft of the flexible display panel. Of course, in the present application, the hollow portions 20 of each supporting layer 2 are not limited to the above-mentioned shapes, for example, their shapes may also include unconventional shapes such as S-shape and Y-shape.

[0076] In some embodiments, Figure 1 , Figure 2 and Figure 4 As shown, the display component provided in the embodiment of the present application also includes a foam adhesive layer (not shown in the figure) located between the at least two supporting layers 2 and the flexible display module 3, and a supporting layer 2 close to the flexible display module 3 is bonded to the flexible display module 3 through the foam adhesive layer.

[0077] Furthermore, a support layer 2 close to the bearing assembly 1 can be bonded to the bearing assembly 1 by adhesive. For example, a support layer 2 close to the bearing assembly 1 is bonded to the first middle frame 11, the second middle frame 12 and the shaft assembly 13 by glue or double-sided tape.

[0078] For example, adjacent support layers 2 may be bonded together by gluing, that is, all support layers 2 are bonded together to form a whole; or, the at least two support layers 2 may be integrally formed. Specifically, this solution is applicable to the support layer solutions given in the above embodiments, and is particularly applicable to the embodiment in which the hollow portions of the above support layers are alternately arranged, because in the scheme in which the hollow portions of the support layers are alternately arranged, it is necessary to avoid the displacement between the layers as much as possible to ensure the complementarity of the patterns of the hollow regions.

[0079] Of course, exemplary, adjacent support layers 2 may not be connected to each other, so as to maintain the freedom of each support layer 2 to obtain better tensile properties.

[0080] In addition, an embodiment of the present application further provides a display device, which includes any of the display components described above.

[0081] Specifically, in the display assembly provided in the embodiment of the present application, the flexible display module may include a flexible display screen, structures such as a protective cover plate and a protective film located on the front of the display screen, and structures such as a heat dissipation module located on the back of the display screen.

[0082] For example, the non-display area of ​​the edge of the protective cover can be bonded to the edge of the supporting component by foam glue; taking the folding display component as an example, since the hinge assembly divides the first middle frame and the second middle frame, the edges of the first middle frame and the second middle frame can be respectively bonded to the edge of the protective cover by "C"-shaped foam glue.

[0083] Specifically, the flexible display screen may be an OLED panel.

[0084] Specifically, the display device provided in the embodiment of the present application may further include a rear housing located on a side of the bearing assembly away from the flexible display module, a main circuit board and other functional modules, etc. All of them will not be described in detail here.

[0085] Specifically, the display device can be applied to display devices such as tablet computers and mobile phones.

[0086] It should be noted that in some embodiments of the present disclosure, the display assembly and the display device may also include other structures, which may be determined according to actual needs, and the embodiments of the present disclosure are not limited to this. In addition, the size and material selection of each structure provided in the embodiments of the present disclosure are not limited to the above embodiments, and their basic requirements can be referred to the description above, which will not be repeated here. Furthermore, the drawings of the present application are only schematic diagrams, and the size and proportion of each part of the structure in the figure do not represent the actual size proportion of each structure.

[0087] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
