[0044] The technical solutions of the embodiments of the present application will be described clearly and completely in the following description with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0045] ​In related technologies, in view of the heat dissipation problem of OLED display screens, researchers have carried out a series of innovative researches from the aspects of materials and structures. In terms of materials, better heat-conducting metals or composite materials are used as the substrate or backplane of the display screen to improve the conduction efficiency of heat. In terms of structure, more reasonable heat dissipation structures are designed, such as adding heat dissipation fins, optimizing the layout of heat dissipation holes, etc., to increase the heat dissipation area and improve the heat dissipation efficiency. In addition to the innovation of materials and structures, researchers have also explored various heat dissipation technologies to meet the heat dissipation needs of OLED vehicle-mounted displays. Among them, liquid cooling technology has become a research hotspot due to its high heat dissipation efficiency and good stability. Liquid cooling technology realizes efficient heat dissipation by setting up cooling liquid circulation channels on the back of the display screen and using the flow of liquid to carry away heat. In addition, heat pipe technology, phase change material technology, etc. have also been applied to the heat dissipation of OLED vehicle-mounted displays, and good heat dissipation effects have been achieved.

[0046] In order to ensure the overall stability of the flexible display product, two support members are arranged on the back of the display module of the slidable flexible display product for protection. The first support member is used to protect the display module, and the second support member is used to fix the whole machine.

[0047] At present, the heat is easily concentrated in a local area of the second support member, and the heat cannot be well conducted in the second support member, which affects the heat uniformity of the display module.

[0048] Therefore, embodiments of the present application provide a display module and a display device, which aim to improve the heat uniformity of the display module.

[0049] Reference Figure 1 As shown in FIG. 1, a display module disclosed by embodiments of the present application includes a light-emitting panel 10 and a support member located on one side of the light-emitting panel.

[0050] Specifically, the light-emitting panel 10 includes a bending area A and a non-bending area B located on at least one side of the bending area A. The bending area A refers to an area whose shape changes when the display module is folded or bent, and the non-bending area B refers to an area whose shape does not change when the display module is folded or bent. It can be understood that in the embodiments of the present application, the display module is a slidable product, that is, the display module can slide under the action of a driving mechanism; the display area of the display module can overlap with the non-bending area B1 on the left side of the bending area A, that is, the non-bending area B1 can display picture content; the bending area A is an area where the light-emitting panel 10 participates in the deformation of the slidable product; and the non-bending area B2 on the right side of the bending area A is an area connected with the driving mechanism.

[0051] The light-emitting panel 10 refers to a device in a display module that can emit light of different colors. Image content can be displayed using the light-emitting panel 10. Specifically, the light-emitting panel 10 may include a layer of light-emitting devices, a polarizer, and a cover plate 30, etc., stacked sequentially (it can be understood that the polarizer and cover plate 30, etc., are all located on the light-emitting side of the light-emitting device layer). In some embodiments, the light-emitting panel 10 may also include a color filter layer and a touch layer.

[0052] The support member is disposed on the backlight side of the light-emitting panel 10, that is, the support member is disposed on the side of the light-emitting device layer away from the cover plate 30. In the embodiment of this application, the support member includes a first support layer 21 and a second support layer 22. The first support layer 21 is disposed on one side of the light-emitting panel 10, and the second support layer 22 is disposed on the side of the first support layer 21 away from the light-emitting panel 10.

[0053] The thickness of the first support layer 21 (i.e., the dimension of the first support layer 21 in the light-emitting direction of the light-emitting panel 10) is greater than or equal to 50 μm and less than or equal to 150 μm. For example, the thickness of the first support layer 21 can be 50 μm, 80 μm, 100 μm, 120 μm, 150 μm, etc. The material of the first support layer 21 can be stainless steel.

[0054] Meanwhile, the first support layer 21 includes a first patterned portion 211 and at least one first non-patterned portion 212. The first patterned portion 211 corresponds to the bending area A of the light-emitting panel 10, and the first non-patterned portion 212 corresponds to the non-bending area B1 of the light-emitting panel 10. That is, the orthographic projection of the first patterned portion 211 on the light-emitting panel 10 is located within the bending area A or overlaps with the bending area A; the orthographic projection of the first non-patterned portion 212 on the light-emitting panel 10 is located within the non-bending area B1 or overlaps with the non-bending area B1.

[0055] The elastic modulus of the first patterned portion 211 is greater than or equal to 50 MPa and less than or equal to 500 MPa. For example, the elastic modulus of the first patterned portion 211 can be 50 MPa, 100 MPa, 200 MPa, 300 MPa, 500 MPa, etc. The elastic modulus of the first non-patterned portion 212 is greater than or equal to 2 GPa and less than or equal to 6 GPa. For example, the elastic modulus of the first non-patterned portion 212 can be 2 GPa, 3 GPa, 4 GPa, 5 GPa, 6 GPa, etc.

[0056] It should be noted that after the support component is patterned, the deformation resistance of the first patterned part 211 will also change accordingly; the elastic modulus of the first patterned part 211 here refers to the equivalent elastic modulus of this part of the structure.

[0057] The thickness of the second support layer 22 (i.e. the dimension of the second support layer 22 in the light-emitting direction of the light-emitting panel 10) is greater than or equal to 200 μm and less than or equal to 800 μm. Exemplarily, the thickness of the second support layer 22 can be 200 μm, 300 μm, 400 μm, 600 μm, 800 μm, etc. The material of the second support layer 22 can be stainless steel.

[0058] Meanwhile, the second support layer 22 comprises a second patterned portion 221 and at least one second non-patterned portion 222, the second patterned portion 221 corresponding to the bending area A of the light-emitting panel 10, and the second non-patterned portion 222 corresponding to the non-bending area B1 of the light-emitting panel 10. That is, the orthographic projection of the second patterned portion 221 on the light-emitting panel 10 is located in the bending area A or overlaps with the bending area A; and the orthographic projection of the second non-patterned portion 222 on the light-emitting panel 10 is located in the non-bending area B1 or overlaps with the non-bending area B1.

[0059] The elastic modulus of the second patterned portion 221 is greater than or equal to 50 MPa and less than or equal to 500 MPa. Exemplarily, the elastic modulus of the second patterned portion 221 can be 50 MPa, 100 MPa, 200 MPa, 300 MPa, 500 MPa, etc. The elastic modulus of the second non-patterned portion 222 is greater than or equal to 2 GPa and less than or equal to 6 GPa. Exemplarily, the elastic modulus of the second non-patterned portion 222 can be 2 GPa, 3 GPa, 4 GPa, 5 GPa, 6 GPa, etc.

[0060] It should be noted that the anti-deformation capability of the second patterned portion 222 will change after the support is patterned; the elastic modulus of the second patterned portion 222 here refers to the equivalent elastic modulus of the portion structure.

[0061] In addition, the first patterned portion 211 and the first non-patterned portion 212 of the first support layer 21, and the second patterned portion 221 and the second non-patterned portion 22 of the second support layer 22 are all discontinuous structures, but this will result in that the heat of the light-emitting panel 10 cannot be well transferred in the support, affecting the heat uniformity of the display module.

[0062] To this end, in the embodiment of the present application, the first transition part 213 is arranged between the first pattern part 211 and the first non-pattern part 212, and the two sides of the first transition part 213 are connected with the first pattern part 211 and the first non-pattern part 212 respectively. The first transition part 213 can be made of the same material as the first support layer 21, and the first transition part 213 is arranged between the first pattern part 211 and each first non-pattern part 212. For example, the first support layer 21 includes the first pattern part 211 and the first non-pattern parts 212 located on both sides of the first pattern part 211, and the first transition part 213 is arranged between the first pattern part 211 and the first non-pattern parts 212 on both sides.

[0063] Meanwhile, the second transition part 223 is arranged between the second pattern part 221 and the second non-pattern part 222, and the two sides of the second transition part 223 are connected with the second pattern part 221 and the second non-pattern part 222 respectively. The second transition part 223 can be made of the same material as the second support layer 22, and the second transition part 223 is arranged between the second pattern part 221 and each second non-pattern part 222. For example, the second support layer 22 includes the second pattern part 221 and the second non-pattern parts 223 located on both sides of the second pattern part 221, and the second transition part 223 is arranged between the second pattern part 221 and the second non-pattern parts 223 on both sides.

[0064] By using the first transition part 213 to connect the first pattern part 211 and the first non-pattern part 212 of the first support layer 21 and using the second transition part 223 to connect the second pattern part 221 and the second non-pattern part 222 of the second support layer 22, the heat generated by the light-emitting panel 10 can be transferred through the first support layer 21 and the second support layer 22 and finally dissipated from the display module, thereby improving the heat dissipation performance of the display module.

[0065] In an embodiment, the first non-pattern part 212, the first pattern part 211 and the first transition part 213 can be integrally formed, and the second non-pattern part 222, the second pattern part 221 and the second transition part 223 can be integrally formed. In this way, the first support layer 21 and the second support layer 22 can form a full-surface support for the light-emitting panel 10, thereby better improving the heat dissipation performance of the display module.

[0066] In an embodiment, the length of the first transition portion 213 and the second transition portion 223 is greater than or equal to 0.5 mm and less than or equal to R / 2, where R represents the bending radius of the light-emitting panel. In this way, the first transition portion 213 and the second transition portion 223 can be prevented from being excessively bent. In actual applications, the first transition portion 213 and the second transition portion 223 can need to be determined according to the processing technology and the assembly process.

[0067] In an alternative embodiment, the embodiments of the present application also provide a display module, in which the elastic modulus of the first transition portion 213 gradually increases from one end connected to the first pattern portion 211 to one end connected to the first non-pattern portion 212, and the elastic modulus of the second transition portion 222 gradually increases from one end connected to the second pattern portion 221 to one end connected to the second non-pattern portion 222.

[0068] Specifically, since the elastic modulus of the first non-pattern portion 212 and the second non-pattern portion 222 is much greater than the elastic modulus of the first pattern portion 211 and the second pattern portion 221, and a sudden change in the elastic modulus can cause the display module to produce a crease, by setting the first transition portion 213 and the second transition portion 223 to have a gradually changing elastic modulus, the problem of a sudden change in the elastic modulus from the first non-pattern portion 212 to the first pattern portion 211 and from the second non-pattern portion 222 to the second pattern portion 221 can be reduced. The elastic modulus of the first transition portion 213 and the second transition portion 223 can increase from 500 MPa to 2 GPa.

[0069] The gradual change in the elastic modulus of the first transition portion 213 and the second transition portion 223 can be achieved by patterning the first transition portion 213 and the second transition portion 223. In specific applications, the patterning can be performed by opening holes in the first transition portion 213 and the second transition portion 223, and the holes can be arranged in a certain pattern (for example, in an array). The shape of the holes (referring to the shape of the normal projection of the holes on the light-emitting panel 10) can include a strip shape, a circular shape, a diamond shape, an oval shape, and the like.

[0070] In an embodiment, the pattern of the second transition portion 223 is the same as the pattern of the second pattern portion 221. It can be understood that the second pattern portion 221 itself has a pattern, and the pattern on the second pattern portion 221 can be a plurality of holes. Therefore, the same pattern can be formed on the second transition portion 223, that is, the same holes as those on the second pattern portion 221 can be opened on the second transition portion 223. In this way, the patterning process of the second transition portion 223 and the second pattern portion 221 can be facilitated, and the two portions do not need to be patterned separately.

[0071] In an embodiment, the pattern of the second transition portion 223 can also be different from the pattern of the second pattern portion 221. Since the elastic modulus of the second transition portion 223 gradually increases from the end connected to the second pattern portion 221 to the end connected to the second non-pattern portion 222, in order to meet this requirement, the pattern of the second transition portion 223 can be independently designed, and in this case, the pattern of the second transition portion 223 is different from the pattern of the second pattern portion 221.

[0072] In an embodiment, the pattern of the second transition portion 223 can include a plurality of openings. In the embodiment of the present application, the plurality of openings of the second transition portion 223 are arranged in multiple rows from the end connected to the second pattern portion 221 to the end connected to the second non-pattern portion 222, and the size of the openings gradually increases in the direction from the end connected to the second non-pattern portion 222 to the end connected to the second pattern portion 221. It can be understood that the larger the size of the openings, the smaller the elastic modulus of the corresponding position of the second transition portion 223, and thus the gradual change of the size of the openings can achieve the gradual change of the elastic modulus of the second transition portion 223. It should be noted that the size of the openings is defined differently according to the shape of the openings. For example, if the shape of the openings is long strip-shaped, the size of the openings refers to the length of the openings; if the shape of the openings is circular, the size of the openings refers to the diameter of the openings; if the shape of the openings is diamond-shaped or oval-shaped, the size of the openings refers to the area of the orthographic projection of the openings on the light-emitting panel 10.

[0073] In an embodiment, the pattern of the second transition portion 223 can include a plurality of openings. And in the direction from the end connected to the second non-pattern portion 222 to the end connected to the second pattern portion 221, the second transition portion 223 can be divided into a plurality of units 2230, and at least one row of openings is arranged in each unit 2230. The size of the openings in each unit 2230 is the same, and the size of the openings in the unit 2230 farther away from the second non-pattern portion 222 is larger.

[0074] For example, four rows of openings are arranged in each unit 2230, and the size of the openings is the same. The unit closest to the second non-pattern portion 222 is the first unit, and the size of the openings in the first unit is a; the second unit is adjacent to the first unit, and the size of the openings in the second unit is 2a; and thus by gradually increasing the size of the openings in each unit, the gradual change of the elastic modulus of the second transition portion 223 can be achieved.

[0075] In an alternative embodiment, the embodiment of the present application also provides a display module, in which the pattern of the first pattern portion 211 includes a plurality of first openings, and the pattern of the second pattern portion 221 includes a plurality of second openings.

[0076] Specifically, since the second support layer 22 is farther away from the light-emitting panel than the first support layer 21, when the light-emitting panel 10 is bent, the second support layer 22 has a greater bending disturbance than the first support layer 21, and thus the second pattern portion 221 of the second support layer 22 needs to have a smaller elastic modulus. To this end, in the embodiment of the present application, the first opening size of the first pattern portion 211 is greater than the second opening size of the second pattern portion 221.

[0077] Exemplarily, the ratio of the size of the second opening to the size of the first opening is 8:1. Setting the ratio of the size of the second opening to the size of the first opening in this range can make the first support layer 21 and the second support layer 22 have better bending performance.

[0078] In an embodiment, the length of the first opening is greater than or equal to 6 mm and less than or equal to 12 mm, the width of the first opening is greater than or equal to 0.1 mm and less than or equal to 0.5 mm, and the spacing between the first openings can be greater than or equal to 0.1 mm and less than or equal to 0.5 mm.

[0079] The length of the second opening is greater than or equal to 50 mm and less than or equal to 70 mm, the width of the second opening is greater than or equal to 0.3 mm and less than or equal to 1.0 mm, and the spacing between the second openings can be greater than or equal to 0.5 mm and less than or equal to 3.0 mm.

[0080] In an alternative embodiment, the embodiment of the present application also provides a display module, in which the orthographic projection of the first support layer 21 on the first plane K overlaps the orthographic projection of the light-emitting panel 10 on the first plane K, and the orthographic projection of the second support layer 22 on the first plane K is located within the orthographic projection of the first support layer 21 on the first plane K.

[0081] Specifically, the first plane K is parallel to the plane in which the light-emitting panel 10 is located, and thus the orthographic projection of the first support layer 21 on the first plane K overlapping the orthographic projection of the light-emitting panel 10 on the first plane K means that the size of the first support layer 21 is substantially the same as the size of the light-emitting panel 10; the orthographic projection of the second support layer 22 on the first plane K being located within the orthographic projection of the first support layer 21 on the first plane K means that the size of the second support layer 22 is smaller than the size of the first support layer 21 and the light-emitting panel 10. In this way, the second support layer 22 is less likely to be damaged when bent, which is conducive to improving the service life of the display module.

[0082] In an embodiment, a spacer layer 40 is arranged on the outer periphery of the light-emitting panel 10, the first support layer 21 and the second support layer 22.

[0083] Specifically, since the size of the cover plate 30 is generally larger than the size of the light-emitting panel 10, and the size of the light-emitting panel 10 and the first support layer 21 is larger than the size of the second support layer 22, a space is formed at the outer periphery of the light-emitting panel 10, the first support layer 21 and the second support layer 22. In the embodiment of the present application, the spacer layer 40 is formed by filling the space with an elastic material (for example, glue), so that the display module can be buffered to a certain extent from the impact from the side, thereby reducing the damage caused by the impact to the display module, and prolonging the service life of the display module.
