[0001] The present application relates to the field of display technology, and in particular to a display module and a display device. Background Art

[0002] With the update and iteration of display technology, consumers' demand for display panels has become more diversified and personalized. Flexible displays have attracted much attention due to their bendability, foldability and flexibility. Among them, rollable displays, as one of the development trends of flexible display technology, can not only meet consumers' pursuit of large screens and wide viewing angles, but also have a small size and are easy to carry.

[0065] See also Figures 1 to 3 , Figure 1A schematic diagram of the structure of a display module in an embodiment of the present application is shown. A display module 10 provided in an embodiment of the present application includes: a rotating shaft 100 and a flexible display panel 200, the outer periphery of the rotating shaft 100 includes a curved surface 110 and a cross section 120, the radius of the curved surface 110 gradually increases in the circumferential direction of the rotating shaft 100, the cross section 120 is connected between the head end and the end of the curved surface 110, the flexible display panel 200 includes a cover plate 210, a flexible screen body 220 and a functional layer 230, the cover plate 210 has a first area 211 and a second area 212 arranged along a first direction. Domain 212, the flexible screen body 220 is arranged on one side of the cover plate 210 and is located in the first area 211, the functional layer 230 is arranged on the side of the cover plate 210 close to the flexible screen body 220 and is located in the second area 212, the functional layer 230 is wound around at least part of the periphery of the curved surface 110 along the circumference of the rotating shaft 100, and the flexible display panel 200 has a rolled state. In the rolled state, the flexible screen body 220 is at least partially wound around the periphery of the second area 212 of the cover plate 210 along the circumference of the rotating shaft 100.

[0066] In the display module 10 of this embodiment, the functional layer 230 is wound around at least a portion of the periphery of the curved surface 110 along the circumference of the rotating shaft 100, and the second area 212 of the cover plate 210 is wound around the periphery of the functional layer 230 along the circumference of the rotating shaft 100. The second area 212 of the cover plate 210 located on the periphery of the functional layer 230 is fixed to the curved surface 110 on the periphery of the rotating shaft 100 through the functional layer 230. The flexible display panel 200 has a rolled state. In the rolled state, the flexible display panel 200 has the flexible screen body 220 at least partially rolled around the outer periphery of the second area 212 of the cover plate 210 along the circumference of the rotating shaft 100, and the first area 211 of the cover plate 210 is rolled around the outer periphery of the flexible screen body 220 along the circumference of the rotating shaft 100. Since the first area 211 of the cover plate 210 and the second area 212 of the cover plate 210 belong to two parts of the same cover plate 210, the first area 211 of the cover plate 210 rolled around the outer periphery of the flexible screen body 220 is always tightened, and the first area 211 of the cover plate 210 will apply a radial force pointing to the center of the rotating shaft to the flexible screen body 220 to press the flexible screen body 220, limit the reverse warping of the flexible screen body 220, and thereby reduce the risk of peeling of each film layer in the flexible screen body 220.

[0067] To summarize, the display module 10 in this embodiment fixes the second area 212 of the cover plate 210 on the curved surface 110 on the periphery of the rotating shaft 100, so that the first area 211 of the cover plate 210 wound on the periphery of the flexible screen body 220 is always tensioned, so as to press the flexible screen body 220 with the help of the first area 211 of the cover plate 210, limit the reverse warping of the flexible screen body 220, and reduce the risk of peeling of each film layer in the flexible screen body 220.

[0068] It should be noted that, since the problem of reverse warping of the flexible screen 220 is solved in this embodiment by adopting an outer cover plate 210 and setting a functional layer 230 on the second area 212 of the cover plate 210, the size of the existing flexible screen 220 is not adjusted during the whole process, so the typesetting rate of the flexible screen 220 during the processing will not be affected.

[0069] See also Figure 2 and Figure 3 In some embodiments, the cross section 120 is parallel to the radial direction of the curved surface 110 at the maximum radius position.

[0070] In this embodiment, by making the cross section 120 parallel to the radial direction of the maximum radius of the curved surface 110 , the length of the flexible screen 220 wound around the outer periphery of the second region 212 of the cover plate 210 along the circumferential direction of the rotating shaft 100 can be increased.

[0071] In some embodiments, the flexible display panel 200 includes a supporting film layer 240 , and the supporting film layer 240 is disposed on a side of the flexible screen body 220 facing away from the cover plate 210 .

[0072] In this embodiment, the supporting film layer 240 is arranged on the side of the flexible screen body 220 away from the cover plate 210, so that the flexible display panel 200 in the rolled state can be rolled up along the circumference of the rotating shaft 100, and the supporting film layer 240 is rolled up on at least a part of the periphery of the second area 212 of the cover plate 210, and the flexible screen body 220 is rolled up on the periphery of the supporting film layer 240, and then the flexible screen body 220 is supported by the supporting film layer 240 to prevent the flexible screen body 220 from being damaged when rolled up.

[0073] In some embodiments, in the rolled state, the supporting film layer 240 is rolled around at least a portion of the outer circumference of the second region 212 of the cover plate 210 .

[0074] In some embodiments, the flexible display panel 200 includes a protective film layer 250 , and the protective film layer 250 is disposed on a side of the supporting film layer 240 facing away from the flexible screen body 220 .

[0075] In this embodiment, the protective film layer 250 is arranged on the side of the supporting film layer 240 away from the flexible screen body 220, so that the flexible display panel 200 in the curled state is wound around at least part of the outer periphery of the second area 212 of the cover plate 210 along the circumference of the rotating shaft 100, and the supporting film layer 240 is wound around the outer periphery of the protective film layer 250, thereby facilitating the isolation of the supporting film layer 240 and the cover plate 210 with the help of the protective film layer 250, thereby protecting the cover plate 210, preventing the supporting film layer 240 from scratching the cover plate 210, and avoiding light leakage from the flexible screen body 220.

[0076] In some embodiments, in the rolled state, the protection film layer 250 is rolled around at least a portion of the outer circumference of the second region 212 of the cover plate 210 .

[0077] See also Figures 2 to 3 In some embodiments, the functional layer 230 includes a first adhesive layer 231 , and the first adhesive layer 231 and the flexible screen body 220 are arranged at intervals along the first direction.

[0078] In this embodiment, by configuring the functional layer 230 to include the first adhesive layer 231 , the second region 212 of the cover plate 210 can be bonded to the curved surface 110 by means of the first adhesive layer 231 , thereby improving the firmness of the connection between the second region 212 of the cover plate 210 and the curved surface 110 .

[0079] In some embodiments, the first adhesive layer 231 is arranged along the first direction close to one side of the flexible screen body 220, and is spaced apart from the cross section 120 along the direction in which the radius of the curved surface 110 gradually decreases. The first adhesive layer 231 is arranged along the first direction away from one side of the flexible screen body 220, and is wound around the curved surface 110 along the direction in which the radius of the curved surface 110 gradually decreases.

[0080] In this embodiment, by arranging the first adhesive layer 231 on one side of the flexible screen body 220 along the first direction and the cross section 120 to be arranged at intervals in the direction in which the radius of the curved surface 110 gradually decreases, the first adhesive layer 231 on one side of the flexible screen body 220 along the first direction and the cross section 120 can be staggered in the direction in which the radius of the curved surface 110 gradually decreases, so that the cover plate 210 whose projection on the curved surface 110 is located between the side of the first adhesive layer 231 on the flexible screen body 220 along the first direction and the cross section 120 and the curved surface 110 forms a receiving groove (not marked), thereby facilitating that in the flexible display panel 200 in the rolled state, when the side of the flexible screen body 220 close to the first adhesive layer 231 along the first direction is misaligned in the circumferential direction of the rotating shaft 100, the side of the flexible screen body 220 close to the first adhesive layer 231 along the first direction is prevented from interfering with the cross section 120 and the second adhesive layer 260.

[0081] In some embodiments, the first adhesive layer 231 is close to one side of the flexible screen body 220 along the first direction, and the distance between the cross section 120 in the direction in which the radius of the curved surface 110 gradually decreases is a first value D1, and the spacing between the first adhesive layer 231 and the flexible screen body 220 is a second value D2 in the first direction, and the first value D1 is less than or equal to the second value D2.

[0082] In this embodiment, by setting the side of the first adhesive layer 231 close to the flexible screen body 220 along the first direction, the distance between the cross section 120 in the direction in which the radius of the curved surface 110 gradually decreases is set to a first value D1, which is less than or equal to the spacing between the first adhesive layer 231 and the flexible screen body 220, and the dimension in the first direction is set to a second value D2. The cross section 120 and the side of the flexible screen body 220 close to the first adhesive layer 231 along the first direction can be arranged in sequence along the direction in which the radius of the curved surface 110 gradually increases.

[0083] In some embodiments, when the first value D1 is equal to the second value D2, in the curled state, the flexible screen body 220 contacts the cross section 120 along the first direction on one side close to the first adhesive layer 231, and the flexible screen body 220 is wound around at least part of the periphery of the second area 212 of the cover plate 210 along the direction in which the radius of the curved surface 110 gradually increases along the side away from the first adhesive layer 231 along the first direction.

[0084] In some embodiments, when the first value D1 is less than the second value D2, in the curled state, the side of the flexible screen body 220 close to the first adhesive layer 231 along the first direction is arranged at intervals with the cross section 120 along the direction in which the radius of the curved surface 110 gradually increases, and the side of the flexible screen body 220 away from the first adhesive layer 231 along the first direction is wound around at least part of the periphery of the second area 212 of the cover plate 210 along the direction in which the radius of the curved surface 110 gradually increases.

[0085] In this embodiment, by arranging the side of the flexible screen body 220 close to the first adhesive layer 231 along the first direction and spacing it with the cross section 120 along the direction in which the radius of the curved surface 110 gradually increases, the flexible screen body 220 that is misaligned in the circumferential direction of the rotating shaft 100 can be accommodated by means of the gap between the side of the flexible screen body 220 close to the first adhesive layer 231 along the first direction and the cross section 120, thereby preventing the side of the flexible screen body 220 close to the first adhesive layer 231 along the first direction from interfering with the cross section 120.

[0086] In some embodiments, one side of the first adhesive layer 231 away from the flexible screen body 220 along the first direction is flush with one side of the cover plate 210 in the first direction, and one side of the flexible screen body 220 away from the first adhesive layer 231 along the first direction is flush with the other side of the cover plate 210 in the first direction.

[0087] See also Figures 2 to 3 In some embodiments, along the first direction, the side of the supporting film layer 240 close to the first adhesive layer 231 extends out of the flexible screen body 220, and the extension length is a third value D3, the third value D3 is less than the second value D2, the first value D1 is equal to the third value D3, and the side of the protective film layer 250 close to the first adhesive layer 231 along the first direction is flush with the side of the supporting film layer 240 close to the first adhesive layer 231 along the first direction.

[0088] In this embodiment, by setting the side of the supporting film layer 240 close to the first adhesive layer 231 along the first direction to extend out of the flexible screen body 220, and the extension length is a third value D3, and the third value D3 is less than the second value D2, so that when the flexible display panel 200 is in a rolled state, with the help of the protective film layer 250, the side of the supporting film layer 240 close to the first adhesive layer 231 along the first direction contacts the section 120, and the side of the flexible screen body 220 wound on the outer periphery of the supporting film layer 240 close to the first adhesive layer 231 along the first direction is in contact with the section 120, so as to position the side of the flexible screen body 220 wound on the outer periphery of the supporting film layer 240 close to the first adhesive layer 231 along the first direction and the section 120, thereby ensuring that the section 120 and the side of the flexible screen body 220 close to the first adhesive layer 231 along the first direction are arranged in sequence along the direction in which the radius of the curved surface 110 gradually increases.

[0089] In some embodiments, in the curled state, the protective film layer 250 is close to the side of the first adhesive layer 231 along the first direction and contacts the cross section 120. The protective film layer 250 is away from the side of the first adhesive layer 231 along the first direction and is wound around at least part of the periphery of the second area 212 of the cover plate 210 in the direction in which the radius of the curved surface 110 gradually increases. The supporting film layer 240 is close to the side of the first adhesive layer 231 along the first direction and contacts the cross section 120. Along the first direction, the supporting film layer 240 is away from the side of the first adhesive layer 231 and is wound around the periphery of the protective film layer 250 in the direction in which the radius of the curved surface 110 gradually increases. The flexible screen body 220 is away from the side of the first adhesive layer 231 and is wound around the periphery of the supporting film layer 240 in the direction in which the radius of the curved surface 110 gradually increases.

[0090] In this embodiment, since the distance between the side of the supporting film layer 240 close to the first adhesive layer 231 along the first direction and the side of the first adhesive layer 231 close to the flexible screen body 220 along the first direction is smaller than the distance between the first adhesive layer 231 and the flexible screen body 220 in the first direction, when the side of the protective film layer 250 close to the first adhesive layer 231 along the first direction contacts the section 120 and the side of the supporting film layer 240 close to the first adhesive layer 231 along the first direction contacts the section 120, the flexible screen body 220 wound on the outer periphery of the supporting film layer 240 close to the first adhesive layer 231 along the first direction is arranged at intervals with the section 120 along the circumferential direction of the rotating shaft 100.

[0091] In some embodiments, the third value D3 is between 100 um and 500 um.

[0092] In some embodiments, a side of the supporting film layer 240 close to the first adhesive layer 231 along the first direction and a side of the flexible screen body 220 close to the first adhesive layer 231 along the first direction are spaced apart by D13 along the first direction, and D13 is between 200um and 500um.

[0094] In this embodiment, by setting the size of the second area 212 of the cover plate 210 in the first direction to a fourth value D4, the fourth value D4 is less than or equal to the sum of the size of the curved surface 110 in the circumferential direction of the rotating shaft 100 and the fifth value, the length of the first adhesive layer 231 wound on the curved surface 110 in the direction in which the radius of the curved surface 110 gradually decreases can be increased.

[0095] See also Figure 4 In some embodiments, the fourth value D4 is equal to the sum of the size of the curved surface 110 in the circumferential direction of the rotating shaft 100 and the fifth value.

[0096] In this embodiment, by setting the fourth value D4 equal to the sum of the circumferential dimension of the curved surface 110 in the rotating shaft 100 and the fifth value, the first adhesive layer 231 can contact the cross section 120 after being wound on the curved surface 110 along the first direction away from the side of the flexible screen body 220 along the direction in which the radius of the curved surface 110 gradually decreases.

[0097] In some embodiments, in the curled state, the first adhesive layer 231 is away from the side of the flexible screen body 220 along the first direction and contacts the cross section 120, and the protective film layer 250 is away from the side of the first adhesive layer 231 along the first direction and is wound around the outer periphery of the second area 212 of the cover plate 210 in the direction in which the radius of the curved surface 110 gradually increases.

[0098] In this embodiment, the protective film layer 250 is close to the first adhesive layer 231 along the first direction and contacts the cross section 120, and the protective film layer 250 is away from the first adhesive layer 231 along the first direction and is wound around the outer periphery of the second area 212 of the cover plate 210 in the direction in which the radius of the curved surface 110 gradually increases.

[0099] In some embodiments, the thickness D14 of the cover plate 210 is between 15 um and 60 um.

[0100] In some embodiments, the elongation at break of the cover plate 210 is greater than 5%.

[0101] See also Figures 1 to 3 In some embodiments, the fourth value D4 is between 1 / 8 and 3 / 4 of the sum of the size of the curved surface 110 in the circumferential direction of the rotating shaft 100 and the fifth value.

[0102] In this embodiment, by setting the fourth value D4 between 1 / 8 and 3 / 4 of the sum of the circumferential dimension of the curved surface 110 on the rotating shaft 100 and the fifth value, after the first adhesive layer 231 is wound around the curved surface 110 in a direction in which the radius of the curved surface 110 gradually decreases, a gap is provided between the side of the first adhesive layer 231 that is away from the flexible screen body 220 along the first direction and the cross section 120.

[0103] In some embodiments, along the first direction, a gap is provided between the side of the first adhesive layer 231 facing away from the flexible screen body 220 and the cross section 120 .

[0104] In some embodiments, in the curled state, along the direction in which the radius of the curved surface 110 gradually increases, the protective film layer 250 is sequentially wound from the section 120 around the periphery of the curved surface 110 between the first adhesive layer 231 and the section 120 and the periphery of the second area 212 of the cover plate 210 .

[0105] See also Figures 1 to 3 In some embodiments, the flexible display panel 200 includes a second adhesive layer 260, which is disposed on a side of the protective film layer 250 away from the supporting film layer 240. A dimension D6 of the second adhesive layer 260 in the first direction is less than or equal to a dimension D7 of a gap between the first adhesive layer 231 and the cross section 120 along the first direction away from the flexible screen body 220, and a direction in which the radius of the curved surface 110 gradually decreases. A dimension D8 of the protective film layer 250 in the first direction is greater than a dimension D6 of the second adhesive layer 260 in the first direction.

[0106] In this embodiment, in the curled state, along the direction in which the radius of the curved surface 110 gradually increases, the second adhesive layer 260 is wound around the periphery of the curved surface 110 between the first adhesive layer 231 and the section 120, the protective film layer 250 is wound around the periphery of the second adhesive layer 260, the supporting film layer 240 is wound around the periphery of the protective film layer 250, the flexible screen body 220 is wound around the periphery of the supporting film layer 240, and the flexible screen body 220 is fixed to the curved surface 110 between the first adhesive layer 231 and the section 120 via the second adhesive layer 260. The fixing effect of the second adhesive layer 260 limits the reverse warping of the flexible screen body 220 and reduces the risk of peeling of each film layer in the flexible screen body 220.

[0107] In some embodiments, in the curled state, the second adhesive layer 260 is wound around the periphery of the curved surface 110 between the first adhesive layer 231 and the cross section 120 along the direction in which the radius of the curved surface 110 gradually increases, and the protective film layer 250 is wound around the periphery of the second adhesive layer 260 and the periphery of the second area 212 of the cover plate 210 in sequence.

[0108] See also Figure 1 and Figure 5 In some embodiments, the distance between the side of the second adhesive layer 260 facing away from the cover plate 210 and the side of the cover plate 210 facing away from the second adhesive layer 260 is a sixth value D9. In the direction in which the radius of the curved surface 110 gradually increases, the difference between the maximum radius of the curved surface 110 and the minimum radius of the curved surface 110 is a seventh value D10. The difference between the sixth value D9 and the seventh value D10 is between -20um and 20um.

[0109] In the conventional flexible display panel 200, a first area 211 of the cover plate 210 and a second area 212 of the cover plate 210 form a radial step difference along the maximum radius of the curved surface 110 at the section 120. In this embodiment, by setting the difference between the sixth value D9 and the seventh value D10 to be between -20um and 20um, the step difference formed at the section 120 between the first area 211 of the cover plate 210 and the second area 212 of the cover plate 210 can be reduced, thereby reducing the risk of black spots being generated at the step difference between the first area 211 of the cover plate 210 and the second area 212 of the cover plate 210 in the flexible screen body 220 wound around the outer periphery of the second area 212 of the cover plate 210.

[0111] In some embodiments, the distance between the side of the first adhesive layer 231 facing away from the cover plate 210 and the side of the cover plate 210 facing away from the second adhesive layer 260 is an eighth value D11, and the eighth value D11 is equal to the thickness D12 of the second adhesive layer.

[0112] See also Figure 6 In some embodiments, the functional layer 230 includes a supporting layer 232, which is located on one side of the flexible screen body 220 in the first direction and contacts the flexible screen body 220, and the supporting layer 232 is bonded to the side of the cover plate 210 close to the flexible screen body 220, and the side of the supporting layer 232 facing away from the second area 212 of the cover plate 210 is flush with the side of the flexible screen body 220 facing away from the first area 211 of the cover plate 210; the side of the supporting layer 232 facing away from the flexible screen body 220 along the first direction is flush with the side of the cover plate 210 in the first direction, and the side of the flexible screen body 220 facing away from the supporting layer 220 along the first direction is flush with the other side of the cover plate 210 in the first direction.

[0113] In this embodiment, in the curled state, along the direction in which the radius of the curved surface 110 gradually increases, the support layer 232 is wound from the cross section 120 around the outer circumference of the rotating shaft 100 for at least one circle, and the flexible screen body 220 is wound around the outer circumference of the second area 212 of the cover plate 210. Since the support layer 232 is wound around the outer circumference of the rotating shaft 100 for at least one circle, the curling radius of the flexible screen body 220 is increased, and the risk of warping of the flexible screen body 220 after curling is reduced.

[0114] It should be additionally explained that the material of the support layer 232 includes foam.

[0115] In some embodiments, in a direction in which the radius of the curved surface 110 gradually increases, the support layer 232 is wound around the outer circumference of the rotating shaft 100 from the cross section 120 .

[0116] In some embodiments, at least one circle of support layer 232 is wound around the outer circumference of the rotating shaft 100 .

[0117] In this embodiment, by winding at least one circle of the support layer 232 around the outer circumference of the rotating shaft 100, the curling radius of the flexible screen body 220 can be increased, and the risk of warping of the curled flexible screen body 220 can be reduced.

[0118] In some embodiments, two opposite sides of the supporting film layer 240 in the first direction are flush with two opposite sides of the cover plate 210 in the first direction.

[0119] In this embodiment, the side of the support layer 232 facing away from the cover plate 210 is flush with the side of the flexible screen body 220 facing away from the cover plate 210. In the curled state, along the direction in which the radius of the curved surface 110 gradually increases, the support film layer 240 is wound around the periphery of the rotating shaft 100 from the cross section 120, and the support layer 232 and the flexible screen body 220 are wound around the periphery of the support layer 232 in sequence. The second area 212 of the cover plate 210 is wound around the periphery of the support layer 232, and the first area 211 of the cover plate 210 is wound around the periphery of the flexible screen body 220.

[0121] In this embodiment, in the curled state, along the direction in which the radius of the curved surface 110 gradually increases, the protective film layer 250 is wound around the outer periphery of the rotating shaft 100 from the cross section 120 , and the supporting film layer 240 is wound around the outer periphery of the protective film layer 250 from the cross section 120 .

[0122] The present application also proposes a display device, comprising any one of the display modules 10 described above.

[0123] In the display device of this embodiment, the functional layer 230 is wound around at least a portion of the periphery of the curved surface 110 along the circumference of the rotating shaft 100, and the second area 212 of the cover plate 210 is wound around the periphery of the functional layer 230 along the circumference of the rotating shaft 100. The second area 212 of the cover plate 210 located at the periphery of the functional layer 230 is fixed to the curved surface 110 on the periphery of the rotating shaft 100 via the functional layer 230. The flexible display panel 200 has a rolled state. In the rolled state, the flexible display panel 200 has the flexible screen body 220 at least partially rolled around the outer periphery of the second area 212 of the cover plate 210 along the circumference of the rotating shaft 100, and the first area 211 of the cover plate 210 is rolled around the outer periphery of the flexible screen body 220 along the circumference of the rotating shaft 100. Since the first area 211 of the cover plate 210 and the second area 212 of the cover plate 210 belong to two parts of the same cover plate 210, the first area 211 of the cover plate 210 rolled around the outer periphery of the flexible screen body 220 is always tightened, and the first area 211 of the cover plate 210 will apply a radial force pointing to the center of the rotating shaft to the flexible screen body 220 to press the flexible screen body 220, limit the reverse warping of the flexible screen body 220, and thereby reduce the risk of peeling of each film layer in the flexible screen body 220.

[0124] To summarize, the display device in this embodiment fixes the second area 212 of the cover plate 210 on the curved surface 110 on the periphery of the rotating shaft 100, so that the first area 211 of the cover plate 210 wound on the periphery of the flexible screen body 220 is always stretched tight, so as to press the flexible screen body 220 with the help of the first area 211 of the cover plate 210, limit the reverse warping of the flexible screen body 220, and reduce the risk of peeling of each film layer in the flexible screen body 220.
