[0048] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0049] Figure 1 It is a schematic structural diagram of a display module provided by an embodiment of the present application. Referring to Figure 1 , the display module 10 may include: a display panel 101 and a support component 102 located on the non-display side of the display panel 101.

[0050] Figure 2 It is a top view of a display panel provided by an embodiment of the present application. Referring to Figure 2It can be seen that the display panel 101 can have a non-bending area 101a and a bending area 101b. The non-bending area 101a can also be referred to as a normal display area, and the bending area 101b can also be referred to as a bending display area.

[0051] Among them, the support component 102 has a plate-like structure, and the support component 102 includes a first support structure 1021 and a second support structure 1022. Among them, the orthographic projection of the first support structure 1021 on the display panel 101 is located in the non-bending area 101a and is used to support the non-bending area 101a. The orthographic projection of the second support structure 1022 on the display panel 101 is located in the bending area 101b and is used to support the bending area 101b.

[0052] Reference Figure 1 It can be seen that the first support structure 1021 at least includes a first film layer 10211. The density of the material of the first film layer 10211 is less than the density threshold. Since the density of the material of the first film layer 10211 included in the first support structure 1021 is less than the density threshold, the weight of the first support structure 1021 is relatively light, which can avoid the heavy weight of the display module 10 from affecting the thinness and lightness of the display module 10.

[0053] In summary, the embodiment of the present application provides a display module, which includes a display panel and a support component located on the non-display side of the display panel. By arranging the support component on the non-display side of the display panel, the display panel can be effectively supported, and the support effect is good. Moreover, for the first support structure in the support component that supports the non-bending area of the display panel, the density of the material of the first film layer included in the first support structure is small, so that the weight of the support component can be relatively light, which can avoid the heavy weight of the display module from affecting the thinness and lightness of the display module.

[0054] Optionally, the density threshold can be 2 g / cm 3 (grams per cubic centimeter). That is, the density of the material of the first film layer 10211 can be less than 2 g / cm 3 .

[0055] As a first optional implementation manner, reference Figure 1, the first support structure 1021 may further include a second film layer 10212 stacked with the first film layer 10211. The density of the material of the second film layer 10212 is greater than that of the material of the first film layer 10211. That is to say, in addition to including the first film layer 10211 with a lighter weight, the first support structure 1021 may further include the second film layer 10212 with a heavier weight, thereby ensuring the effective support of the first support structure 1021 for the non-bending area 101a of the display panel 101. In addition, the thickness of the second film layer 10212 may be less than or equal to the thickness of the first film layer 10211. That is to say, the second film layer 10212 with a heavier weight in the first support structure 1021 is thinner, which can avoid the overweight of the first support structure 1021 and ensure the thinness and lightness of the display module 10.

[0056] Optionally, the density of the material of the second film layer 10212 may be greater than 3 g / cm 3 . For example, greater than 5 g / cm 3 .

[0057] Optionally, the thickness range of the first film layer 10211 may be 20 μm (micrometers) to 300 μm, and the thickness range of the second film layer 10212 may be 10 μm to 50 μm.

[0058] In this first implementation manner, the material of the first film layer 10211 may be a hard resin (such as polymethyl methacrylate, or acrylic) or an epoxy resin. Of course, it may also be a carbon fiber board. The material of the second film layer 10212 may be a metal material, such as stainless steel (steel use stainless, SUS) or titanium alloy.

[0059] Among them, if the material of the first film layer 10211 is polymethyl methacrylate or epoxy resin, the first film layer 10211 may be fabricated by a coating process. For example, the liquid material is first coated on the surface of the second film layer 10212, and then the liquid material is cured to obtain the first film layer 10211 stacked with the second film layer 10212. If the material of the first film layer 10211 is a carbon fiber board, the first film layer 10211 may be directly formed, and then the first film layer 10211 is adhered to the second film layer 10212 through a pressure-sensitive adhesive (PSA).

[0060] As a second optional implementation manner, referring to Figure 3 , the surface of the second film layer 10212 close to the first film layer 10211 has a plurality of first grooves A1. The first part of the first film layer 10211 is located in the plurality of first grooves A1, and the second part of the first film layer 10211 is located on the surface of the second film layer 10212 provided in the plurality of first grooves A1.

[0061] By designing a plurality of first grooves A1 on the surface of the second film layer 10212 and making a first portion of the first film layer 10211 located within the plurality of first grooves A1, the adhesion between the first film layer 10211 and the second film layer 10212 can be improved, ensuring the reliability of the support assembly 102.

[0062] Figure 4 It is a top view of a second film layer provided by an embodiment of the present application. Refer to Figure 4 , the plurality of first grooves A1 can be strip-shaped grooves, and at least some of the plurality of first grooves A1 are arranged along the first direction X and extend along the second direction Y. The second direction Y can intersect the first direction X. Of course, the plurality of first grooves A1 can also not be strip-shaped grooves. For example, Figure 5 in, the plurality of first grooves A1 can be arranged in an array on the surface of the second film layer 10212.

[0063] In the embodiment of the present application, the depth of the first groove A1 can be less than the thickness of the second film layer 10212. That is to say, the first groove A1 is not a through groove, so that the contact surface between the first film layer 10211 and the second film layer 10212 includes not only the side surface but also the bottom surface of the first groove A1, increasing the contact area between the first film layer 10211 and the second film layer 10212 and improving the adhesion between the first film layer 10211 and the second film layer 10212.

[0064] In this second implementation manner, the material of the first film layer 10211 can be a hard resin (such as polymethyl methacrylate, or acrylic) or an epoxy resin. The material of the second film layer 10212 can be a metal material, such as SUS or titanium alloy.

[0065] Among them, the first film layer 10211 can be fabricated by a coating process. For example, first fill and infiltrate a liquid material into the plurality of first grooves A1 of the second film layer 10212, and coat the liquid material on the surface of the second film layer 10212 provided with the plurality of first grooves A1, and then cure the liquid material to obtain the first film layer 10211 laminated with the second film layer 10212.

[0066] Optionally, the range of the thickness h1 of the support assembly 102 can be from 100 μm to 300 μm. Among them, the thickness of the support assembly 102 is the sum of the thickness of the first film layer 10211 and the thickness of the second film layer 10212. The range of the thickness h11 of the second portion of the first film layer 10211 located on the surface of the second film layer 10212 provided with the plurality of first grooves A1 is from 20 μm to 200 μm. The range of the thickness h12 of the second film layer 10212 is from 20 μm to 200 μm.

[0067] Reference Figure 3 It can be seen that the shape of the orthographic projection of the first groove A1 on the reference plane can be trapezoidal. Among them, the reference plane can be perpendicular to the extension direction of the first groove A1 and perpendicular to the surface of the second film layer 10212.

[0068] Among them, the length of the first groove near the opening of the first groove is less than the length away from the opening of the first groove. The ranges of the length r1 of the first groove near the opening of the first groove and the length r2 away from the opening of the first groove are both 0.1 mm to 5 mm, and the distance r3 (the groove depth of the first groove) between the side of the first groove near the groove opening and the side away from the opening of the first groove ranges from 20 μm to 100 μm. The distance r4 between the axes of two adjacent first grooves ranges from 0.5 mm to 10 mm.

[0069] Of course, in addition to being trapezoidal, the shape of the orthographic projection of multiple first grooves A1 on the reference plane can also be other shapes, such as Figure 6 a rectangle, Figure 7 a strip with arc-shaped ends or Figure 8 a parallelogram (or rhombus), etc. The embodiments of the present application do not limit this. Among them, when the first groove A1 is a parallelogram, the angle range between one side of the first groove A1 and the surface of the second film layer 10212 can be 30° (degrees) to 150°.

[0070] As a third alternative implementation, referring to Figure 9 and Figure 10 , the second film layer 10212 includes a stacked third sub-film layer 102121 and a fourth sub-film layer 102122. The surface of the third sub-film layer 102121 close to the fourth sub-film layer 102122 has a second groove A2. The fourth sub-film layer 102122 has a strip-shaped first through hole B1. The first through hole B1 communicates with the second groove A2, and the axis of the first through hole B1 and the axis of the second groove A2 are collinear.

[0071] Among them, the first part of the first film layer 10211 can be located in the second groove A2 and the first through hole B1, and the second part of the first film layer 10211 is located on the surface of the fourth sub-film layer 102122 away from the third sub-film layer 102121. The orthographic projection of the first film layer 10211 on the reference plane is in an I shape. The reference plane is perpendicular to the extension direction of the through hole and perpendicular to the surface of the second film layer 10212.

[0072] By making the orthographic projection of the first film layer 10211 on the reference plane in an I shape, the contact area between the first film layer 10211 and the second film layer 10212 can be increased, ensuring the adhesion between the first film layer 10211 and the second film layer 10212.

[0073] In this third implementation, the material of the first film layer 10211 can be a hard resin (such as polymethyl methacrylate, or acrylic) or an epoxy resin. The material of the second film layer 10212 can be a metallic material, such as SUS or a titanium alloy.

[0074] Among them, the second film layer 10212 can be fabricated in two parts (fabricating the third sub-film layer 102121 and the fourth sub-film layer 102122 respectively), and then the third sub-film layer 102121 and the fourth sub-film layer 102122 are bonded by a pressure-sensitive adhesive. Thus, the process of fabricating the support assembly 102 includes: etching the surface of the first sheet to form the second groove A2 to obtain the third sub-film layer 102121; etching the second sheet to form the first through hole B1 to obtain the fourth sub-film layer 102122; bonding the third sub-film layer 102121 and the fourth sub-film layer 102122 and making the first through hole B1 communicate with the second groove A2; filling and infiltrating the liquid material into the second groove A2 through the first through hole B1. The liquid material can fill the second groove A2 and the first through hole B1, and the liquid material is also located on the surface of the fourth sub-film layer 102122 away from the third sub-film layer 102121; performing a curing treatment on the liquid material to obtain the first film layer 10211 laminated with the second film layer 10212.

[0075] Optionally, the thickness h2 of the support assembly 102 can range from 100 μm to 300 μm. The thickness s1 of the portion of the first film layer 10211 located in the second groove A2 (i.e., the depth of the second groove A2) ranges from 20 μm to 50 μm. The thickness s2 of the portion of the first film layer 10211 located in the first through hole B1 (the thickness of the fourth sub-film layer 102122) ranges from 20 μm to 50 μm. The thickness s3 of the portion of the first film layer 10211 located on the surface of the fourth sub-film layer 102122 away from the third sub-film layer 102121 ranges from 20 μm to 50 μm. The length L1 of the projection of the portion of the first film layer 10211 located in the second groove A2 on the reference plane can be greater than 1 / 3 of the length L2 of the projection of the portion of the first film layer 10211 located on the surface of the fourth sub-film layer 102122 away from the third sub-film layer 102121 on the reference plane, and less than the length L2 of the projection of the portion of the first film layer 10211 located on the surface of the fourth sub-film layer 102122 away from the third sub-film layer 102121 on the reference plane, that is, 1 / 3L2 < L1 < L2.

[0076] As a fourth optional implementation, refer to Figure 11, the first film layer 10211 may include a first sub-film layer 102111 and a second sub-film layer 102112, and the first sub-film layer 102111 and the second sub-film layer 102112 may be respectively located on both sides of the second film layer 10212.

[0077] Optionally, the thickness h3 of the support component 102 may range from 100 μm to 300 μm. The thickness of the support component 102 is the sum of the thickness of the first film layer 10211 and the thickness of the second film layer 10212. The thickness of the second film layer 10212 may range from 20 μm to 50 μm.

[0078] In this fourth implementation manner, the material of the first film layer 10211 may be a hard resin (such as polymethyl methacrylate, or acrylic) or an epoxy resin. Of course, it may also be a carbon fiber board. The material of the second film layer 10212 may be a metal material, such as SUS or a titanium alloy.

[0079] Wherein, if the material of the first film layer 10211 is polymethyl methacrylate or an epoxy resin, the first film layer 10211 may be fabricated by a coating process. For example, the liquid material is first coated on two surfaces of the second film layer 10212, and then the liquid material is cured to obtain the first sub-film layer 102111 and the second sub-film layer 102112 located on both sides of the second film layer 10212. If the material of the first film layer 10211 is a carbon fiber board, the first sub-film layer 102111 and the second sub-film layer 102112 may be directly formed, and then the first sub-film layer 102111 is adhered to one surface of the second film layer 10212 through a pressure-sensitive adhesive, and the second sub-film layer 102112 is adhered to the other surface of the second film layer 10212 through a pressure-sensitive adhesive.

[0080] In the embodiments of the present application, the material of the second support structure 1022 of the support component 102 may be the same as the material of the second film layer 10212, and the second film layer 10212 of the second support structure 1022 and the first support structure 1021 may be an integral structure. Since generally, the elastic modulus of the material of the second film layer 10212 is greater than the modulus threshold, that is, the elastic modulus of the material is relatively large and the flexibility is relatively poor. Thus, referring to Figure 4 and Figure 5 , a plurality of second through holes B2 arranged in a staggered manner may be designed on the second support structure 1022, so as to be able to reduce the bending stress of the display module 10 located in the bending area 101b, and be able to avoid defects such as delamination of the film layer and device failure of the display module 10 located in the bending area 101b. The yield rate of the display module 10 is relatively high and the display effect is relatively good.

[0081] Of course, the material of the second support structure 1022 may also be different from that of the second film layer 10212, and the elastic modulus of the material of the second support structure 1022 may be less than the modulus threshold. This material can be obtained by filling and curing a liquid material. Since the elastic modulus of the material of the second support structure 1022 is small, that is, the material of the second support structure 1022 is a flexible material. The design of the flexible material can also reduce the bending stress of the display module 10 in the bending area 101b, avoid defects such as delamination of the film layer and device failure of the display module in the bending area 101b, and the yield rate of the display module 10 is high and the display effect is good.

[0082] Optionally, the material of the second support structure 1022 may be a flexible polymer filler or an elastic polymer. The elastic modulus of this material ranges from dozens to hundreds of Mpa, which is much smaller than the elastic modulus of the material of the second film layer 10212 (the elastic modulus of the material of the second film layer 10212 ranges from 3 GPa (gigapascals) to 6 GPa). Therefore, the material of the second support structure 1022 is softer than the material of the second film layer 10212, and the stress during bending is smaller, which can avoid delamination or fracture of the film layer of the display module in the bending area 101b. Optionally, the material of the second support structure 1022 may be one of thermoplastic polyurethane elastomer (TPU), polymethylmethacrylate (PMMA), and silicone rubber. For example, the material of the second support structure 1022 is UV-curable PMMA, and the preparation process is simple, and its elastic modulus is below 500 Mpa.

[0083] In the embodiment of the present application, referring to Figure 2 , the bending area 101b may include a first bending area 101b1 and a second bending area 101b2. The extending direction of the first bending area 101b1 intersects with the extending direction of the second bending area 101b2. For example, the first bending area 101b1 extends along the second direction Y, and the second bending area 101b2 extends along the first direction X. The overlapping area of the first bending area 101b1 and the second bending area 101b2 constitutes a double bending area a. That is, the display panel 101 may be a bi-fold display panel. Of course, the bending area 101b may also only include one bending area 101b, and the display panel 101 may be a single-fold display panel. The embodiment of the present application does not limit this.

[0084] If the display panel 101 is a two-way foldable display panel, since the double bending area a needs to bear alternating stresses in two directions relative to the single bending areas (the areas of the first bending area 101b1 and the second bending area 101b2 except for the double bending area a), it is easy to have problems such as module delamination or failure of light-emitting devices in the display panel. Thus, referring to Figure 12 , the size of the second through hole B2 in the double bending area a can be made smaller than that of the second through hole B2 in the single bending area. By designing the size of the second through hole B2 in the double bending area a to be smaller, the double bending area a can better bear the alternating stresses in two directions, ensuring the yield rate of the support assembly 102.

[0085] In the embodiment of the present application, referring to Figure 13 , the display module 10 may further include: a protective layer 103 located on the non-display side of the support assembly 102 close to the display panel 101, a buffer layer 104 located between the protective layer 103 and the support assembly 102, and a polarizer (POL) 105, an optically clear adhesive (OCA) 106, and a cover film 107 that are stacked on the display side of the display panel 101. In addition, adjacent film layers can be bonded by the optical adhesive 106 or the pressure-sensitive adhesive.
