[0046] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0047] In the related art, before bending the bonding area of the display panel, a layer of glue is coated on the bonding area to improve the impact resistance of the bent area after bending. However, since the glue contacts the side wall of the polarizer in the display module during coating, and this contact causes the glue to climb upward along the side wall of the polarizer under the action of capillary effect, resulting in a problem of too thick glue layer at this position, and further causing the bent thick position of the display panel to be prone to fracture, and the closer the polarizer is to the bending starting point, the higher the risk.

[0048] In view of this, the embodiments of the present application propose a display module and a display device, aiming to solve the problem that the bent part of the display module breaks during bending and improve the yield of the display module.

[0049] Refer to Figure 1 and Figure 3 As shown, a display module disclosed in an embodiment of the present application includes a display panel 10, a polarizer 20, and a reinforcing layer 30.

[0050] Specifically, refer to Figure 1 and Figure 3 As shown, the display panel 10 may include a main body part 11 and a bent part 12. The bent part 12 is located on one side of the main body part 11 and is connected to the main body part 11. Among them, the main body part 11 may include a display area of the display panel 10 and a non-display area surrounding the display area. In the display area, the display panel can emit light to realize the display of graphic content; the bent part 12 may include a bonding area of the display panel. Devices such as the driving chip of the display panel may be arranged in the bonding area, and the part where the driving chip is located in the bonding area will be located on the backlight side of the display panel 10 after being bent. In the embodiment of the present application, a heat dissipation film layer is also provided on the backlight side of the main body part 11 of the display panel 10.

[0051] At the same time, the display panel 10 in the embodiment of the present application may be an active light-emitting display panel, such as an Organic Light Emitting Diode (OLED) display panel, an Active Matrix Organic Light Emitting Diode (AMOLED) display panel, a Passive Matrix OLED display panel, a Quantum Dot Light Emitting Diodes (QLED) display panel, etc.

[0052] The display panel 10 in the embodiments of the present application may also be a liquid crystal display panel. The present application does not limit the type of the display panel, which may be a vertical electric field type liquid crystal display panel, such as a Twisted Nematic (TN) type liquid crystal display panel or a Multidomain Vertical Alignment (MVA) type liquid crystal display panel, or may also be a horizontal electric field type liquid crystal display panel, such as a Fringe Field Switching (FFS) type liquid crystal display panel or an In-Plane Switching (IPS) type liquid crystal display panel.

[0053] Referring Figure 3 As shown, the polarizer 20 is disposed on the light-emitting side of the display panel 10, and the polarizer 20 covers at least the display area in the main body portion 11 of the display panel 10. The polarizer 20 can improve the contrast and clarity of the display module and reduce reflection and glare by controlling the polarization direction of light. The polarizer 20 generally includes a polarization layer, a protective layer, and an adhesive layer, wherein the polarization layer functions to change the polarization direction of light, the protective layer functions to protect the polarization layer, and the adhesive layer functions to connect with the display panel 10.

[0054] Referring Figure 3 As shown, the reinforcing layer 30 includes a first portion 31 and a second portion 32 that are connected to each other, wherein the position of the first portion 31 corresponds to the position of the main body portion 11 in the display panel 10, and the position of the second portion 32 corresponds to the position of the bent portion 12 in the display panel 10. That is, the first portion 31 covers the main body portion 11, the second portion 32 covers the bent portion 12, and the first portion 31 completely coincides with the main body portion 11, and the second portion 32 completely coincides with the bent portion 12. It should be noted that in actual processes, the first portion 31 and the main body portion 11 and the second portion 32 and the bent portion 12 cannot completely coincide, so as long as the two overlap within a certain tolerance value, they can be regarded as coinciding.

[0055] At the same time, the second portion 32 can follow the bending of the bent portion 12, and after the bent portion 12 is bent, in the direction perpendicular to the normal direction of the main body portion 11, the second portion 32 is located on the side of the bent portion 12 away from the main body portion 11. After the reinforcing layer 30 is formed, the polarizer 20 can be connected to the display panel 10. At this time, the first portion 31 is located between the polarizer 20 and the display panel 10; the second portion 32 covering the bent portion 12 can enhance the impact resistance of the bent portion 12.

[0056] In an embodiment of the present application, at the edge position of the polarizer 20 close to the bent portion 12, the surface of the first portion 31 away from the main body portion 11 is flush with the surface of the second portion 32 away from the bent portion 12.

[0057] Specifically, the edge position of the polarizer 20 close to the bent portion 12 can also be understood as the starting point of the bent portion 12. At this position, the surface of the first portion 31 away from the main body portion 11 is flush with the surface of the second portion 32 away from the bent portion 12. That is to say, the thicknesses of the first portion 31 and the second portion 32 of the reinforcing layer 30 are the same at this position (in actual process, the thicknesses of the first portion 31 and the second portion 32 can be regarded as the same within a tolerance value of 1%). And in the embodiment of the present application, after the reinforcing layer 30 is formed on the display panel 10, the polarizer 20 is then connected to the main body portion 11 of the display panel 10. In this way, during the formation of the reinforcing layer 30, the reinforcing layer 30 cannot climb along the side wall of the polarizer 20, resulting in a situation where the thickness of part of the reinforcing layer 30 is too thick, thereby solving the problem that the bent portion 12 of the display module breaks during bending and improving the yield of the display module.

[0058] Refer to Figure 3 As shown, in an embodiment of the present application, the display module may further include a cover plate 40. The cover plate 40 is disposed on the side of the polarizer 20 away from the display panel 10, and the cover plate 40 is connected to the polarizer 20 through an optical adhesive 50.

[0059] In one embodiment, refer to Figure 3 As shown, the material of the reinforcing layer 30 may include an adhesive material. For example, the material of the reinforcing layer 30 may be selected as a photosensitive adhesive. At this time, the polarizer 20 and the display panel 10 can be connected through the first portion 31 of the reinforcing layer 30. That is to say, in this embodiment, the polarizer 20 may not include an adhesive layer, and the polarizer 20 can be directly connected to the display panel 10 through the reinforcing layer 30 with bonding ability.

[0060] During specific preparation, a photosensitive adhesive may be coated on the main body portion 11 and the bent portion 12 of the display panel 10 to form the first portion 31 and the second portion 32 of the reinforcing layer 30 respectively, and no curing treatment is performed after coating; then the polarizer 20 without an adhesive layer can be attached to the main body portion 11 of the display panel 10, and the entire display module is irradiated with ultraviolet light to cure the photosensitive adhesive, and then the subsequent devices of the display module are prepared and the bending of the bent portion 12 is completed. Among them, refer to Figure 4 As shown, when connecting the polarizer 20 and the display panel 10, the edge of the polarizer 20 close to the bent portion 12 can be made to coincide with the edge of the main body portion 11 close to the bent portion 12, which can achieve the effect of reducing the lower border of the display module.

[0061] In this way, since the reinforcing layer 30 is formed before the polarizer 20 is connected to the display panel 10 and is located at the edge of the polarizer 20 near the bent portion 12, and the surface of the first portion 31 away from the main body portion 11 is flush with the surface of the second portion 32 away from the bent portion 12, there will be no problem of excessive thickness in the second portion 32 of the reinforcing layer 30. Furthermore, the problem of breakage occurring in the bent portion 12 of the display module during bending can be solved, improving the yield rate of the display module. At the same time, the connection between the polarizer 20 and the display panel 10 is realized by using the first portion 31 of the reinforcing layer 30, which can reduce the manufacturing cost of the display module.

[0062] In addition, referring to Figure 5 As shown, in order to further enhance the impact resistance of the bent portion 12, a support material 60 can also be filled in the accommodation area formed between the bent portion 12 and the main body portion 11 after bending, so as to provide a supporting force for the side of the bent portion 12 close to the main body portion 11 by using the support material 60. It should be noted that the support material 60 needs to completely fill the accommodation area, and the support material 60 can be selected as a thermosetting adhesive.

[0063] In one embodiment, referring to Figure 6 As shown, the material of the reinforcing layer 30 can include a flexible transparent material. For example, the material of the reinforcing layer 30 can be selected as PET (polyethylene terephthalate) or PI (polyimide), etc. At this time, the reinforcing layer 30 does not have bonding ability. Therefore, the polarizer 20 and the first portion 31 of the reinforcing layer 30, as well as the reinforcing layer 30 and the display panel 10, need to be connected through an adhesive layer, and the material of the adhesive layer can be selected as a pressure-sensitive adhesive. Among them, the thickness of the reinforcing layer 30 is equal to the thickness of the glue coated on the bent portion 12 in the related art.

[0064] In the specific preparation, the reinforcing layer 30 can be first connected to the display panel 10 through an adhesive layer, where the first portion 31 of the reinforcing layer 30 corresponds to the main body portion 11 of the display panel 10, and the second portion 32 of the reinforcing layer 30 corresponds to the bent portion 12 of the display panel 10. Then, the polarizer 20 and the first portion 31 of the reinforcing layer 30 are connected through an adhesive layer, and the subsequent components of the display module are prepared and the bending of the bent portion 12 is completed. Among them, referring to Figure 4 As shown, when connecting the polarizer 20 and the display panel 10, the edge of the polarizer 20 close to the bent portion 12 can be made to coincide with the edge of the main body portion 11 close to the bent portion 12, which can play the role of reducing the lower border of the display module.

[0065] In this way, since the reinforcing layer 30 is formed before the polarizer 20 is connected to the display panel 10 and is located at the edge position of the polarizer 20 close to the bent portion 12, the surface of the first portion 31 away from the main body portion 11 is flush with the surface of the second portion 32 away from the bent portion 12. Therefore, there will be no problem of excessive thickness in the second portion 32 of the reinforcing layer 30, thus solving the problem that the bent portion 12 of the display module breaks during bending and improving the yield of the display module. At the same time, since the reinforcing layer 30 is made of a flexible transparent material, the bent portion 12 of the display panel 10 can have stronger impact resistance.

[0066] In addition, referring to Figure 7 As shown, in order to further enhance the impact resistance of the bent portion 12, a support material 60 can also be filled in the accommodating area formed between the bent portion 12 and the main body portion 11 after the bent portion 12 is bent, so as to provide a supporting force for the side of the bent portion 12 close to the main body portion 11 by using the support material 60. It should be noted that the support material 60 needs to completely fill the accommodating area, and the support material 60 can be selected as a thermosetting adhesive.

[0067] It can be understood that in the above embodiment, the first portion 31 and the second portion 32 can be integrally formed, that is, the first portion 31 and the second portion 32 are formed simultaneously and connected as a whole, so as to avoid cracks between the first portion 31 and the second portion 32, which may affect the subsequent bending of the bent portion 12 or cause the intrusion of water and oxygen.

[0068] In an alternative embodiment, the embodiment of the present application further provides a display module, which includes a display panel 10, a polarizer 20, and a reinforcing layer 30.

[0069] Specifically, the reinforcing layer 30 is disposed on the bent portion 12 of the display panel 10. The reinforcing layer 30 can be bent along with the bent portion 12, and after the bent portion 12 is bent, the reinforcing layer 30 is located on the side of the bent portion 12 away from the main body portion 11. Specifically, the reinforcing layer 30 covers the bent portion 12 to improve the impact strength of the bent portion 12. And in the embodiment of the present application, at the edge position of the polarizer 20 close to the bent portion 12, the surface of the polarizer 20 away from the main body portion 11 is flush with the surface of the reinforcing layer 30 away from the bent portion 12. That is to say, at the starting point position of the bent portion 12, the thickness of the reinforcing layer 30 is the same as the thickness of the polarizer 20 (in actual process, the thicknesses of the reinforcing layer 30 and the polarizer 20 can be regarded as the same within a tolerance value of 1%).

[0070] Referring to Figure 8 and Figure 9As shown, in one embodiment, the reinforcing layer 30 and the polarizer 20 can be integrally formed. That is to say, the reinforcing layer 30 in this embodiment belongs to a part of the polarizer 20, or the polarizer 20 in this embodiment includes an extension section, which is the reinforcing layer 30. Among them, between the polarizer 20 and the main body portion 11 of the display panel 10 and between the reinforcing layer 30 and the bent portion 12 of the display panel 10, they are connected through an adhesive layer 21 (such as Figure 11 ). The adhesive layer 21 can be an adhesive layer included in the polarizer 20 itself, and the material of the adhesive layer can be a pressure-sensitive adhesive.

[0071] In specific preparation, the polarizer 20 including the reinforcing layer 30 can be directly attached to the display panel 10, where the polarizer 20 corresponds to the main body portion 11 of the display panel 10, and the reinforcing layer 30 corresponds to the bent portion 12 of the display panel 10 to protect the bent portion 12, and then the subsequent devices of the display module are prepared and the bending of the bent portion 12 is completed. Among them, referring to Figure 4 As shown, when connecting the polarizer 20 and the display panel 10, the edge of the polarizer 20 close to the bent portion 12 can be made to coincide with the edge of the main body portion 11 close to the bent portion 12, so as to achieve the effect of reducing the lower border of the display module.

[0072] In this way, since the reinforcing layer 30 is formed simultaneously when the polarizer 20 and the display panel 10 are connected, and at the edge position of the polarizer 20 close to the bent portion 12, the surface of the polarizer 20 away from the main body portion 11 is flush with the surface of the reinforcing layer 30 away from the bent portion 12, there will be no problem of excessive thickness in the reinforcing layer 30, thus solving the problem that the bent portion 12 of the display module breaks during bending and improving the yield of the display module; at the same time, the reinforcing layer 30 and the polarizer 20 are integrally formed, which makes it unnecessary to separately prepare the reinforcing layer 30 for the display module, thereby reducing the preparation steps.

[0073] In addition, referring to Figure 10 As shown, in order to further enhance the impact resistance of the bent portion 12, a support material 60 can also be filled in the accommodating area formed between the bent portion 12 and the main body portion 11 after bending to provide a supporting force for the side of the bent portion 12 close to the main body portion 11 by using the support material 60. It should be noted that the support material 60 needs to completely fill the accommodating area, and the support material 60 can be selected as a thermosetting adhesive.

[0074] In this embodiment, since the reinforcing layer 30 needs to be bent along with the bent portion 12, and the reinforcing layer 30 is integrally formed with the polarizer 20, a plurality of through holes can be formed in the reinforcing layer 30, thereby reducing the bending modulus of the reinforcing layer 30, so that the reinforcing layer 30 can be better bent along with the bent portion 12, and reducing the occurrence of fracture of the reinforcing layer 30 during bending. Among them, the plurality of through holes can be evenly distributed on the reinforcing layer 30. For example, the plurality of through holes can be arranged in an array at equal intervals, or the plurality of through holes can also be arranged in a staggered row and column distribution. The shape of the through holes can include strip-shaped, circular, diamond-shaped, square, and polygonal, and those skilled in the art can set according to actual needs.

[0075] In an alternative embodiment, referring to Figure 11 As shown, in the embodiment of the present application, a display module is further provided. In this display module, no reinforcing layer 30 is provided at the bent portion 12 of the display panel 10.

[0076] Specifically, in this embodiment, after connecting the polarizer 20 to the main body portion 11 of the display panel 10, the preparation of the subsequent devices of the display module can be continued and the bending of the bent portion 12 can be performed, and then a support material 60 is filled in the accommodation area formed by the bent portion 12 and the main body portion 11 after bending, so as to use the support material 60 to improve the impact resistance of the bent portion 12. The support material 60 can be selected as a thermosetting adhesive. This can also avoid the situation that the thickness of part of the reinforcing layer 30 is too thick, resulting in fracture of the bent portion 12 during bending, thereby improving the yield rate of the display module. In addition, in this embodiment, the edge of the polarizer 20 close to the bent portion 12 can also be made to coincide with the edge of the main body portion 11 close to the bent portion 12, which can play a role in reducing the lower border of the display module.

[0077] Figure 12 The step flowchart of a preparation method of a display module is shown. Referring to Figure 12 As shown, the embodiment of the present application also discloses a preparation method of a display module, and the preparation method includes:

[0078] Step 201: Provide a display panel 10.

[0079] Specifically, the display panel 10 may include a main body portion 11 and a bent portion 12. The bent portion 12 is located on one side of the main body portion 11 and is connected to the main body portion 11. Among them, the main body portion 11 may include a display area of the display panel 10 and a non-display area surrounding the display area. In the display area, the display panel can emit light to realize the display of graphic content; the bent portion 12 may include a bonding area of the display panel. Devices such as the driving chip of the display panel can be arranged in the bonding area, and the part where the driving chip is located in the bonding area will be located on the backlight side of the display panel 10 after being bent.

[0080] Step 202: Form a strengthening layer 30 on the light-emitting part of the display panel 10.

[0081] Specifically, the strengthening layer 30 includes a first part 31 and a second part 32 which are connected to each other. The position of the first part 31 corresponds to the position of the main body part 11 in the display panel 10, and the position of the second part 32 corresponds to the position of the bent part 12 in the display panel 10. That is, the first part 31 covers the main body part 11, and the second part 32 covers the bent part 12. And the first part 31 completely coincides with the main body part 11, and the second part 32 completely coincides with the bent part 12. It should be noted that in the actual process, the first part 31 and the main body part 11, and the second part 32 and the bent part 12 cannot completely coincide. Therefore, as long as the two overlap within a certain tolerance value, they can be regarded as coinciding.

[0082] At the same time, the second part 32 can be bent along with the bent part 12. After the bent part 12 is bent, in the direction perpendicular to the normal direction of the main body part 11, the second part 32 is located on the side of the bent part 12 away from the main body part 11. After the strengthening layer 30 is formed, the polarizer 20 can be connected to the display panel 10. At this time, the first part 31 is located between the polarizer 20 and the display panel 10; the second part 32 covering the bent part 12 can enhance the impact resistance of the bent part 12.

[0083] Step 203: Attach the polarizer 20 to the side of the strengthening layer 30 away from the substrate 10.

[0084] Specifically, the polarizer 20 is arranged on the light-emitting side of the display panel 10, and the polarizer 20 covers at least the display area in the main body part 11 of the display panel 10.

[0085] At the same time, at the edge position of the polarizer 20 close to the bent part 12, the surface of the first part 31 away from the main body part 11 is flush with the surface of the second part 32 away from the bent part 12.

[0086] Among them, the edge position of the polarizer 20 close to the bent portion 12 can also be understood as the starting point of the bent portion 12. At this position, the surface of the first portion 31 away from the main body portion 11 is flush with the surface of the second portion 32 away from the bent portion 12. That is, the thicknesses of the first portion 31 and the second portion 32 of the reinforcing layer 30 are the same at this position (in actual processes, the thicknesses of the first portion 31 and the second portion 32 can be regarded as the same within a tolerance value of 1%). Moreover, in the embodiment of the present application, after the reinforcing layer 30 is formed on the display panel 10, the polarizer 20 is then connected to the main body portion 11 of the display panel 10. In this way, during the formation of the reinforcing layer 30, the reinforcing layer 30 cannot climb along the side wall of the polarizer 20, which may otherwise cause the situation where the thickness of part of the reinforcing layer 30 is too thick, thus solving the problem that the bent portion 12 of the display module breaks during bending and improving the yield of the display module.

[0087] Based on the same inventive concept, the embodiment of the present application discloses a display device, including any one of the display panels described above in the embodiments of the present application.

[0088] Specifically, the display device may include a computer monitor, a television, a billboard, a laser printer with a display function, a telephone, a mobile phone, a personal digital assistant (PDA), a laptop computer, a digital camera, a portable video camera, a viewfinder, a vehicle, a large-area wall, a screen in a theater, or a stadium sign, etc.

[0089] It should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0090] It should also be noted that in this text, the orientation or positional relationships indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the present application. In addition, relative terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations, nor can they be construed as indicating or implying relative importance. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or terminal device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or terminal device comprising the element.
