[0036] In order to better understand the present application, the display module and display device of the embodiment of the present application are described in detail below with reference to Figures 1 to 11.

[0037] Please refer to FIG. 1 and FIG. 2 . FIG. 1 is a schematic structural diagram of a display module 10 provided in an embodiment of the present application; FIG. 2 is a cross-sectional view of FIG. 1 taken along line AA in an example.

[0038] As shown in Figures 1 and 2, an embodiment of the first aspect of the present application provides a display module 10, which has a bending area WA and a non-bending area YA located on at least one side of the bending area WA in a first direction X. The display module 10 includes a support layer 100 and a flexible display panel 200. The support layer 100 includes a first sub-portion 110 and a second sub-portion 120 connected side by side along the first direction X. At least a portion of the first sub-portion 110 is located in the bending area WA, and the second sub-portion 120 is located in the non-bending area YA. The width of the first sub-portion 110 in the second direction Y is less than the width of the second sub-portion 120 in the second direction Y, and the second direction Y intersects the first direction X. The flexible display panel 200 is disposed on one side of the support layer 100 in the thickness direction Z.

[0039] In the display module 10 provided in the embodiment of the present application, the display module 10 has a bending area WA and a non-bending area YA, and the display module 10 can be bent in the bending area WA. The display module 10 includes a support layer 100 and a flexible display panel 200. The support layer 100 is used to provide support for the flexible display panel 200, and the flexible display panel 200 is used to achieve a bendable display of the display module 10. The support layer 100 includes a first sub-portion 110 and a second sub-portion 120. The first sub-portion 110 is located in the bending area WA, and the second sub-portion 120 is located in the non-bending area YA. The width of the first sub-portion 110 is smaller than the width of the second sub-portion 120, that is, the width of the portion of the support layer 100 located in the bending area WA is smaller than the width of the portion located in the non-bending area YA. When the display module 10 is bent, it can improve the problem of easy peeling of the support layer 100 and the flexible panel at the edge of the bending area WA caused by the stress concentration applied by the first sub-section 110 to the flexible display panel 200, and improve the problem of the film layer of the display module 10 breaking inward from the edge of the bending area, thereby improving the performance of the display module 10.

[0040] Optionally, there are two non-bending areas YA, with the two non-bending areas YA located on either side of the bending area WA in the first direction X. The two non-bending areas YA are brought closer to or further away from each other via the bending area WA. Optionally, there are two second sub-sections 120, with the two second sub-sections 120 connected to either side of the first sub-section 110 in the first direction X. A second sub-section 120 is provided for each non-bending area YA.

[0041] Optionally, the first sub-section 110 and the second sub-section 120 are integrally provided. The first sub-section 110 and the second sub-section 120 are parts of different regions on the support layer 100 that are integrally provided.

[0042] The display module 10 can be folded inward or outward using the bending area WA and the non-bending area YA. When the display module 10 is folded inward, the flexible display panel 200 is folded between the two second sub-sections 120 of the support layer 100. When the display module 10 is folded outward, the two second sub-sections 120 of the support layer 100 are folded between the flexible display panels 200. The display module 10 also has a flattened state, in which the support layer 100 and the flexible display panel 200 are stacked along the thickness direction Z.

[0043] There are many ways to set up the support layer 100, and the support layer 100 includes a layer of support plate 101. Alternatively, for example, as shown in Figure 3, the support layer 100 includes multiple support plates 101 such as foam, support structure plates, etc., and the support plates can be steel plates or carbon fiber plates. It can be that at least one support plate 101 includes a first sub-section 110 and a second sub-section 120, or it can be that multiple support plates 101 include a first sub-section 110 and a second sub-section 120. The multiple support plates 101 can be bonded by an adhesive layer (not shown in the figure). Optionally, when the support layer 100 includes multiple support plates 101, and one of the multiple support plates 101 includes a first sub-section 110 and a second sub-section 120, the support plate 101 on the side away from the flexible display panel 200 among the multiple support plates 101 can include the first sub-section 110 and the second sub-section 120. This is to improve the problem that the outermost support plate 101 is easy to peel off.

[0044] In other embodiments, the supporting layer 100 may include all the structural layers located on the non-display side of the flexible display panel 200, or the supporting layer 100 may include part of the structural layers located on the non-display side of the flexible display panel 200. As long as it is a structural layer located on the non-display side of the flexible display panel 200, it can be set to include the first sub-section 110 and the second sub-section 120.

[0045] Optionally, as shown in FIG5 , the first sub-portion 110 is located in the bending area WA, and the second sub-portion 120 is located in the non-bending area YA. The length of the first sub-portion 110 in the first direction X can be equal to the length of the bending area WA in the first direction X. The length of the second sub-portion 120 in the first direction X can also be equal to the length of the non-bending area YA in the first direction X.

[0046] In other optional embodiments, as shown in Figure 1, the length L1 of the first sub-section 110 in the first direction X is greater than the length L2 of the bending area WA in the first direction X, and part of the first sub-section 110 extends from the bending area WA to the non-bending area YA and is interconnected with the second sub-section 120.

[0047] In these optional embodiments, the length of the first sub-portion 110 is greater than the length of the bending area WA, which can improve the problem of force concentration in the portion of the flexible display panel 200 located in the non-bending area YA but close to the bending area WA, and better improve the problem of easy peeling of the supporting layer 100 and the flexible display panel 200 during the bending process of the display module 10.

[0048] Furthermore, when the display module 10 is used in a display device, the display device also includes a hinge, and the flexible display panel 200 and the support layer 100 are connected to the hinge and are bendable around the hinge. The support layer 100 often needs to cooperate with the hinge. For example, the first sub-portion 110 is connected to the hinge, and the length of the first sub-portion 110 is greater than the length of the bending area WA. When the support layer 100 and the flexible display panel 200 are bent around the hinge, the force concentration on the flexible display panel 200 can be improved, and the problem of adhesion failure between the support layer 100 and the flexible display panel 200 in the bending area WA can be improved.

[0049] Optionally, the ratio of the extension of the first sub-section 110 in the first direction X to the extension of the bending area WA in the first direction X is greater than 1 and less than or equal to 1.2. For example, the ratio of the extension of the first sub-section 110 in the first direction X to the extension of the bending area WA in the first direction X is 1.1, 1.15, 1.2, etc. That is, when the length of the first sub-section 110 in the first direction X is L1 and the length of the bending area WA is L2, L1 and L2 satisfy: L2<L1≤1.2L2.

[0050] In these optional embodiments, when L1 and L2 satisfy the above relationship, it can not only improve the problem that the supporting capacity of the supporting layer 100 is affected by the excessive length of the first sub-section 110 with a smaller width; it can also improve the problem that the supporting layer 100 and the flexible display panel 200 are easily peeled off during the bending process of the display module 10 due to the insufficient length of the first sub-section 110.

[0051] Optionally, the first sub-portion 110 is retracted inwardly from the second sub-portion 120 on one side of the second direction Y, so that the width of the first sub-portion 110 is smaller than the width of the second sub-portion 120 .

[0052] In other optional embodiments, the first sub-section 110 has two first side edges 111 arranged opposite to each other in the second direction Y, and the second sub-section 120 has two second side edges 121 arranged opposite to each other in the second direction Y, and in the second direction Y, the two first side edges 111 are located between the two second side edges 121.

[0053] In these optional embodiments, the two first side edges 111 of the first sub-section 110 are located between the two second side edges 121 of the second sub-section 120, that is, the two first side edges 111 of the first sub-section 110 are retracted into the second side edges 121, and each first side edge 111 is located on the side of each second side edge 121 toward the center of the supporting layer 100 in the second direction Y, which can improve the problem of easy peeling between the flexible display panel 200 and the supporting layer 100 near each first side edge 111.

[0054] Optionally, on both sides of the supporting layer 100 in the second direction Y, the distance between the first side 111 and the second side 121 on one side in the second direction Y is equal to the distance between the first side 111 and the second side 121 on the other side in the second direction Y. For example, as shown in FIG5 , based on the center line of the supporting layer 100 extending in the first direction X, the supporting layer 100 is divided into left and right sides in the second direction Y. The indentation dimension d1 of the left first side 111 relative to the left second side 121 is the same as the indentation dimension d2 of the right first side 111 relative to the right second side 121, so that the force on the flexible display panel 200 is more balanced.

[0055] Optionally, on the same side of the support layer 100, the first side 111 is connected to the second side 121 through the first inclined edge 112, and the distance between the first inclined edges 112 connected to both ends of the same first side 111 gradually increases in the direction close to the edge of the support layer 100.

[0056] In these optional embodiments, the first side 111 and the first inclined sides 112 connected thereto at both ends form a groove, which is recessed toward the middle of the support layer 100 in the second direction Y. As the distance between the first inclined sides 112 connected to both ends of the same first side 111 gradually increases, the size of the groove gradually increases in the direction approaching its opening. This allows the first side 111 to gradually retract as it retracts toward the second side 121, reducing stress concentration issues. It also facilitates the preparation and molding of the support layer 100.

[0057] The first inclined edge 112 can be shaped in a variety of ways. For example, the first inclined edge 112 may be linear, with an obtuse angle between the first inclined edge 112 and the first side edge 111. Alternatively, the first inclined edge 112 may be connected to the first side edge 111 via an arc transition edge, facilitating the preparation of the support layer 100. Alternatively, as shown in FIG4 , the first inclined edge 112 may extend along an arc.

[0058] In some optional embodiments, the width of the first sub-portion 110 in the second direction Y and the width of the second sub-portion 120 in the second direction Y are both greater than the width of the flexible display panel 200 in the second direction Y. The first side edge 111 and the second side edge 121 on the same side of the supporting layer 100 have a first distance H1 in the second direction Y, and the second side edge 121 and the edge of the flexible display panel 200 have a second distance H2 in the second direction Y. The ratio of the first distance to the second distance is 0.2 to 0.8. For example, the ratio of the first distance H1 to the second distance H2 is 0.4, 0.5, 0.7, etc.

[0059] Optionally, the width of the first sub-section 110 in the second direction Y may be the minimum width of the first sub-section 110 in the second direction Y. For example, the width of the first sub-section 110 in the second direction Y is the minimum distance between the two first side edges 111 of the first sub-section 110. Similarly, the width of the second sub-section 120 in the second direction Y is the minimum width of the second sub-section 120 in the second direction Y. For example, the width of the second sub-section 120 in the second direction Y is the distance between the two second side edges 121.

[0060] In these optional embodiments, the width of the first sub-portion 110 and the width of the second sub-portion 120 are both greater than the width of the flexible display panel 200, so that the supporting layer 100 can provide better protection for the flexible display panel 200. The ratio of the first distance H1 to the second distance H2 satisfies the above relationship. On the one hand, it can improve the problem of the supporting layer 100 and the flexible display panel 200 being easily separated due to a too small first distance H1; on the other hand, it can improve the problem of the first sub-portion 110 being too large inwardly retracted due to an excessive first distance H1, which affects the support of the supporting layer 100 for the flexible display panel 200.

[0061] Optionally, the first distance H1 is 0.1 mm to 0.4 mm. For example, the first distance H1 is 0.1 mm, 0.3 mm or 0.4 mm, so that the support layer 100 can provide good support to the flexible display panel 200 and improve the problem of easy peeling between the support layer 100 and the flexible display panel 200.

[0062] Optionally, the second distance H2 is 0.2 mm to 0.5 mm, for example, the second distance H2 is 0.2 mm, 0.3 mm or 0.5 mm, so that the support layer 100 can provide good support to the flexible display panel 200 and also improve the size of the display module 10 caused by the support layer 100 being too large.

[0063] Optionally, opposite edges of the support layer 100 in the first direction X and opposite edges of the flexible display panel 200 in the first direction X are flush with each other, so that the support layer 100 can provide good support for the flexible display panel 200 .

[0064] Optionally, referring to Figures 6 to 8 , the display module 10 further includes a light-transmitting functional layer 300, which is located on the side of the flexible display panel 200 facing away from the support layer 100. In these optional embodiments, the support layer 100 is provided on the non-display side of the flexible display panel 200, and the light-transmitting functional layer 300 is provided on the display side of the flexible display panel 200. The light-transmitting functional layer 300 and the support layer 100 cooperate to provide relatively comprehensive protection for the flexible display panel 200. The light-transmitting functional layer 300 can be disposed in a variety of ways. For example, the edges of the light-transmitting functional layer 300 on both sides in the second direction Y protrude from the flexible display panel 200, or the edges of the light-transmitting functional layer 300 on both sides in the first direction X are flush with the flexible display panel 200.

[0065] In other optional embodiments, the light-transmitting functional layer 300 includes a third sub-portion 310 located in the bending area WA and a fourth sub-portion 320 located at least partially in the non-bending area YA, and the width of at least part of the third sub-portion 310 in the second direction Y is smaller than the width of the fourth sub-portion 320 in the second direction Y.

[0066] In these optional embodiments, the width of the third sub-portion 310 located in the bending area WA on the light-transmitting functional layer 300 is smaller than the width of the fourth sub-portion 320 located in the non-bending area YA, which can improve the problem of easy peeling of the flexible display panel 200 and the light-transmitting functional layer 300 in the bending area WA during the bending process.

[0067] Optionally, the light-transmitting functional layer 300 may include at least one of a cover plate, a polarizer, and a touch film layer. This embodiment of the present application uses the light-transmitting functional layer 300 as an example of a cover plate. In other embodiments, the light-transmitting functional layer 300 may also be a polarizer, a touch film layer, or other structural layer located on the side of the flexible display panel 200 facing away from the support layer 100. Optionally, the touch film layer includes touch traces. When the light-transmitting functional layer 300 includes a third sub-section 310 and a fourth sub-section 320, the touch traces are distributed within the third sub-section 310 and the fourth sub-section 320.

[0068] Optionally, the third sub-portion 310 and the fourth sub-portion 320 are integrally provided. The third sub-portion 310 and the fourth sub-portion 320 are parts of different regions on the integrally provided light-transmitting functional layer 300 .

[0069] Optionally, the length of the third sub-portion 310 in the second direction Y may be the same as or different from the length of the bending area WA in the second direction Y, and the length of the fourth sub-portion 320 in the second direction Y may be the same as or different from the length of the non-bending area YA in the second direction Y.

[0070] For example, the length of the third sub-portion 310 in the first direction X is less than the length of the bending area WA in the first direction X, and a portion of the fourth sub-portion 320 extends from the non-bending area YA to the bending area WA and is interconnected with the third sub-portion 310. In these optional embodiments, the length of the third sub-portion 310 is less than the length of the bending area WA, so that the light-transmitting functional layer 300 can provide better protection for the flexible display panel 200 in the bending area WA and improve the problem of easy peeling between the flexible display panel 200 and the light-transmitting functional layer 300.

[0071] Optionally, the ratio of the length of the third sub-portion 310 in the first direction X to the length of the bending area WA in the first direction X is greater than or equal to 2 / 3. For example, the ratio of the length of the third sub-portion 310 in the first direction X to the length of the bending area WA in the first direction X is 2 / 3, 5 / 6, 7 / 8, etc. For example, the length of the third sub-portion 310 is L3, the length of the bending area WA is L2, and L2 and L3 satisfy the following: 2 / 3L2≤L3<L2. This improves the problem of the third sub-portion 310 being too short, which may cause easy peeling between the flexible display panel 200 and the light-transmitting functional layer 300.

[0072] Optionally, the width of the third sub-section 310 is smaller than the width of the fourth sub-section 320, and one side of the third sub-section 310 in the second direction Y may be retracted relative to the fourth sub-section 320 to improve the problem of easy peeling between the flexible display panel 200 and the light-transmitting functional layer 300 near the edge.

[0073] In other optional embodiments, the third sub-section 310 has two third sides 311 arranged opposite to each other in the second direction Y, and the fourth sub-section 320 has two fourth sides 321 arranged opposite to each other in the second direction Y, and in the second direction Y, the two third sides 311 are located between the two fourth sides 321.

[0074] In these optional embodiments, the two third sides 311 of the third sub-section 310 are located between the two fourth sides 321 of the fourth sub-section 320, that is, the two third sides 311 of the third sub-section 310 are both retracted into the fourth side 321, and each third side 311 is located on the side of each fourth side 321 toward the center of the light-transmitting functional layer 300 in the second direction Y, which can improve the problem of easy peeling between the flexible display panel 200 and the light-transmitting functional layer 300 near each third side 311.

[0075] The third side 311 is retracted relative to the fourth side 321, or the third side 311 is retracted relative to the fourth side 321, which means that: among the third side 311 and the fourth side 321 on the same side of the light-transmitting functional layer 300 in the second direction Y, the third side 311 is located on the side of the fourth side 321 that faces the center of the light-transmitting functional layer 300 in the second direction Y. Similarly, the first side 111 is retracted relative to the second side 121, or the first side 111 is retracted relative to the second side 121, which means that: among the first side 111 and the second side 121 on the same side of the support layer 100 in the second direction Y, the first side 111 is located on the side of the second side 121 that faces the center of the light-transmitting functional layer 300 in the second direction Y.

[0076] In some optional embodiments, on both sides of the light-transmitting functional layer 300 in the second direction Y, a distance D1 between the third side 311 and the fourth side 321 on one side in the second direction Y is equal to a distance D2 between the third side 311 and the fourth side 321 on the other side in the second direction Y. That is, on the same side of the light-transmitting functional layer 300 in the second direction Y, the inward retraction dimensions of the third side 311 relative to the fourth side 321 are the same, thereby making the force applied to the flexible display panel 200 more balanced.

[0077] In some optional embodiments, on the third side 311 and the fourth side 321 on the same side of the light-transmitting functional layer 300, the third side 311 is connected to the fourth side 321 through the second inclined edge 312, and in the direction close to the edge of the light-transmitting functional layer 300, the distance between the second inclined edges 312 connected to the two ends of the same third side 311 gradually increases.

[0078] In these optional embodiments, the third side 311 and the second inclined sides 312 connected to its two ends form a groove, which is recessed toward the middle of the light-transmitting functional layer 300 in the second direction Y. As the distance between the second inclined sides 312 connected to the two ends of the same third side 311 gradually increases, the size of the groove gradually increases in the direction approaching its opening. On the one hand, this allows the third side 311 to gradually retract as it retracts into the fourth side 321, reducing stress concentration issues; on the other hand, it facilitates the preparation and molding of the light-transmitting functional layer 300.

[0079] Optionally, the second inclined edges 312 can be arranged in a variety of ways. For example, the second inclined edges 312 may be linear, with the angle between the interconnected second inclined edges 312 and the third side edge 311 being an obtuse angle. Alternatively, each second inclined edge 312 may be interconnected with the third side edge 311 via a smooth transition edge, facilitating the preparation of the light-transmitting functional layer 300. Alternatively, the extension trajectory of the second inclined edges 312 may be arc-shaped.

[0080] In some optional embodiments, the width of the third sub-section 310 in the second direction Y and the width of the fourth sub-section 320 in the second direction Y are both greater than the width of the flexible display panel 200 in the second direction Y. On the same side of the light-transmitting functional layer 300, the third side 311 and the fourth side 321 have a third distance H3 in the second direction Y, and the fourth side 321 and the edge of the flexible display panel 200 have a fourth distance H4 in the fourth direction. The ratio of the third distance H3 to the fourth distance H4 is 0.1 to 0.8, for example, the ratio of the third distance H3 to the fourth distance H4 is 0.1, 0.6, 0.8, etc.

[0081] Optionally, the width of the third sub-section 310 in the second direction Y is the minimum width of the third sub-section 310 in the second direction Y, and the width of the third sub-section 310 in the second direction Y is the distance between the two third side edges 311 of the third sub-section 310. Optionally, the width of the fourth sub-section 320 in the second direction Y is the minimum width of the fourth sub-section 320 in the second direction Y, and the width of the fourth sub-section 320 in the second direction Y is the distance between the two fourth side edges 321.

[0082] In these optional embodiments, the width of the third sub-portion 310 and the width of the fourth sub-portion 320 are both greater than the width of the flexible display panel 200, so that the light-transmitting functional layer 300 can provide better protection for the flexible display panel 200. The ratio of the third distance H3 to the fourth distance H4 satisfies the above relationship. On the one hand, it can improve the problem of the light-transmitting functional layer 300 and the flexible display panel 200 being easily separated due to a too small third distance H3; on the other hand, it can improve the problem of the third sub-portion 310 being too retracted due to an excessive third distance H3, which affects the protection of the light-transmitting functional layer 300 for the flexible display panel 200.

[0083] Optionally, the value of the third distance H3 is 0.2 mm to 1.0 mm, for example, the value of the third distance is 0.2 mm, 0.5 mm, 1.0 mm, etc., so that the light-transmitting functional layer 300 can not only provide good protection to the flexible display panel 200, but also improve the problem of easy peeling between the light-transmitting functional layer 300 and the flexible display panel 200.

[0084] Optionally, the value of the fourth distance H4 is 1.0 mm to 2.0 mm, for example, the value of the fourth distance H4 is 1.0 mm, 1.3 mm, 2.0 mm, etc., so that the light-transmitting functional layer 300 can not only provide good protection for the flexible display panel 200, but also improve the size of the light-transmitting functional layer 300 so that the size of the display module 10 is too large.

[0085] In some optional embodiments, the first sub-portion 110 and the third sub-portion 310 are both arranged to protrude from the flexible display panel 200 along the second direction Y, and in the second direction Y, the size of the first sub-portion 110 protruding from the flexible display panel 200 is smaller than the size of the third sub-portion 310 protruding from the flexible display panel 200.

[0086] In these optional embodiments, the size of the first sub-section 110 extending out of the flexible display panel 200 is smaller than the size of the third sub-section 310 extending out of the flexible display panel 200, that is, the width of the first sub-section 110 is smaller than the width of the third sub-section 310, so that the light-transmitting functional layer 300 can provide better protection to the flexible display panel 200.

[0087] In some optional embodiments, the second sub-portion 120 and the fourth sub-portion 320 are both arranged to protrude from the flexible display panel 200 along the second direction Y, and in the second direction Y, the size of the second sub-portion 120 protruding from the flexible display panel 200 is smaller than the size of the fourth sub-portion 320 protruding from the flexible display panel 200.

[0088] In these optional embodiments, the size of the second sub-section 120 extending out of the flexible display panel 200 is smaller than the size of the fourth sub-section 320 extending out of the flexible display panel 200, that is, the width of the second sub-section 120 is smaller than the width of the fourth sub-section 320, so that the light-transmitting functional layer 300 can provide better protection to the flexible display panel 200.

[0089] There are various ways to set the number of light-transmitting functional layers 300. The number of light-transmitting functional layers 300 can be one. In other embodiments, as shown in Figures 8 and 9, the number of light-transmitting functional layers 300 is two or more, and at least one of the two or more light-transmitting functional layers 300 includes a third sub-section 310 and a fourth sub-section 320. It is sufficient that at least one light-transmitting functional layer 300 includes the third sub-section 310 and the fourth sub-section 320. Optionally, two adjacent light-transmitting functional layers 300 can be bonded to each other via an adhesive layer 400.

[0090] Optionally, as shown in FIG8 , two or more light-transmitting functional layers 300 each include a third sub-portion 310 and a fourth sub-portion 320 , so as to better improve the problem of easy peeling between the flexible display panel 200 and the light-transmitting functional layer 300 .

[0091] When there are two or more light-transmitting functional layers 300 , the light-transmitting functional layer 300 may be a cover plate, and the number of the cover plates may be two or more; or the light-transmitting functional layer 300 may include at least two of a cover plate, a polarizer, and a touch film layer.

[0092] When there are two or more cover plates, the two or more cover plates all include the third sub-portion and the fourth sub-portion; or, the cover plate farthest from the flexible display panel includes the third sub-portion and the fourth sub-portion.

[0093] In other optional embodiments, as shown in FIG9 , the light-transmitting functional layer 300 farthest from the flexible display panel 200 includes a third sub-portion 310 and a fourth sub-portion 320. The light-transmitting functional layer 300 farthest from the flexible display panel 200 is more easily peeled off from other light-transmitting functional layers 300 or the flexible display panel 200. Setting the light-transmitting functional layer 300 farthest from the flexible display panel 200 to include the third sub-portion 310 and the fourth sub-portion 320 can better alleviate the problem of easy peeling between the light-transmitting functional layer 300 and the flexible display panel 200.

[0094] Referring to Figures 9 to 13 , an embodiment of the second aspect of the present application further provides a display module 10 having a bending area WA and a non-bending area YA located on at least one side of the bending area WA in a first direction X. The display module 10 includes a flexible display panel 200 and a light-transmitting functional layer 300. The light-transmitting functional layer 300 is located on one side of the flexible display panel 200. The light-transmitting functional layer 300 includes a third sub-portion 310 located in the bending area WA and a fourth sub-portion 320 located at least partially in the non-bending area YA. The width of at least a portion of the third sub-portion 310 in the second direction Y is smaller than the width of the fourth sub-portion 320 in the second direction Y.

[0095] In these embodiments, the width of the third sub-portion 310 located in the bending area WA on the light-transmitting functional layer 300 is smaller than the width of the fourth sub-portion 320 located in the non-bending area YA, which can improve the problem of easy peeling of the flexible display panel 200 and the light-transmitting functional layer 300 in the bending area WA during the bending process.

[0096] The configuration of the light-transmitting functional layer 300 is the same as the light-transmitting functional layer 300 provided in any embodiment of the first aspect, and will not be repeated here.

[0097] The third aspect of the present application also provides a display device comprising a display module according to any of the first and second aspects. Since the display device provided by the second aspect includes the display module according to any of the first aspects, the display device provided by the second aspect has the same beneficial effects as the display module according to any of the first aspects, and thus will not be further elaborated here.

[0098] The display device in the embodiments of the present application includes but is not limited to mobile phones, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control systems, smart landline phones, consoles, and other devices with display functions.

[0099] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
