[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] As mentioned in the background technology, in order to meet the folding requirements, the folding display device is made of flexible materials and is relatively thin in thickness. Its cover plate cannot be directly fixed to the middle frame, and a pressure strip is required to protect and fix the display module around. However, the inventors have found that the display device needs to reserve a large area to ensure reliable bonding between the pressure strip and the middle frame. In addition, in order to prevent the slippage of the film layer during assembly and folding from being affected by the interference between the display module and the pressure strip, a space for avoidance needs to be reserved between the display module and the pressure strip. Therefore, the current display device has the problem of wide frame and low protection performance.

[0028] In view of this, the embodiments of the present application are directed to providing a display device and a display apparatus to solve the problems of wide borders and low protection performance of the display device.

[0029] Figure 1 FIG. 1 is a schematic diagram of the structure of a display device provided by an embodiment of the present application. Figure 1 As shown, the display device 100 includes: a display module 101; a middle frame 102, at least a portion of the middle frame 102 is arranged around the display module 101; and a fixed structure, at least a portion of the fixed structure is located between the middle frame 102 and the display module 101; the fixed structure includes a first fixed structure 103 and a second fixed structure 104 arranged adjacent to each other, the first fixed structure 103 is located on a side of the second fixed structure 104 close to the display module 101, and the elastic modulus of the first fixed structure 103 is smaller than the elastic modulus of the second fixed structure 104.

[0030] Specifically, the middle frame 102 surrounds the display module 101 and plays a role in supporting and protecting the display module 101. The fixed structure is used to fix the middle frame 102 and the display module 101, and the fixed structure is divided into two layers. Among them, the first fixed structure 103 is close to the display module 101, and its elastic modulus is small, relatively soft, and can withstand certain deformation. When the display module 101 is assembled or folded, the first fixed structure 103 will not affect the slippage of the membrane layer in the display module 101 while protecting the display module 101. The second fixed structure 104 is located on the side of the first fixed structure 103 away from the display module 101. Its elastic modulus is large and relatively hard, and can provide sufficient support and protection for the display module 101.

[0031] In the related art, a certain escape space needs to be provided between the display module 101 and the middle frame 102 to prevent damage to the display module 101 when the display module 101 is assembled or folded. However, the present solution can fix the display module 101 and the middle frame 102 without reserving an escape space by providing a fixing structure with a soft inner part and a hard outer part, thereby making the frame of the display device 100 narrower.

[0032] The technical solution of this embodiment is to set a fixed structure between the display module 101 and the middle frame 102 to fix and protect the display module 101. The first fixed structure 103 has a small elastic modulus and can be bent to a certain extent. The display module 101 can be folded without reserving avoidance space, and the display module 101 can be fixed more tightly on the middle frame 102. The second fixed structure 104 has a large elastic modulus and can provide support to protect the display module 101 from damage by impact and vibration. Therefore, the technical solution provided in the embodiment of the present application can reduce the border width of the display device 100, and can improve the protection performance of the display module 101, and further improve the appearance and user experience.

[0033] Figure 2 FIG. 2 is a schematic diagram of the structure of a display device provided by another embodiment of the present application. Figure 2 As shown, the display device 100 further includes a glue layer 105 located between the fixing structure and the middle frame 102 .

[0034] Specifically, an adhesive layer 105 is provided between the fixed structure and the middle frame 102 for bonding the fixed structure and the middle frame 102. Exemplarily, the adhesive layer 105 covers the side surface of the fixed structure and the surface of the fixed structure close to the back of the display module 101, ensuring that the surface of the middle frame 102 facing the display module 101 is bonded to the fixed structure through the adhesive layer 105.

[0035] In this embodiment, by providing an adhesive layer 105 between the fixed structure and the middle frame 102, the connection strength between the fixed structure and the middle frame 102 is enhanced, so that the display module 101 is more stable in the display device 100 and is not easily moved or fallen off due to external forces. The adhesive layer 105 can absorb and disperse external impact forces to protect the display module 101 from damage. The adhesive layer 105 covers the side of the fixed structure and the surface close to the back of the display module 101, which can play a sealing role, prevent foreign matter such as moisture and dust from entering the interior of the display module 101, and protect the internal components. Therefore, the technical solution of this embodiment is conducive to improving the reliability of the display device 100.

[0036] Figure 3 FIG. 2 is a schematic diagram of the structure of a display device provided by another embodiment of the present application. Figure 3 As shown, the first fixing structure 103 covers the edge area of ​​the display module 101, and the second fixing structure 104 covers at least a portion of the surface of the first fixing structure 103 away from the first fixing structure 103; preferably, on the display side 1011 of the display module 101, the edge of the second fixing structure 104 away from the middle frame 102 is located on the side of the edge of the first fixing structure 103 away from the middle frame 102 close to the middle frame 102; preferably, on the display side 1011 of the display module 101, the edge of the second fixing structure 104 away from the middle frame 102 and the first fixing structure 1 03, the distance d1 between the edge away from the middle frame 102 is in the range of 0.05-0.1 mm; preferably, on the back panel side 1012 of the display module 101, the edge of the second fixed structure 104 away from the middle frame 102 is located on the side of the edge of the first fixed structure 103 away from the middle frame 102 close to the middle frame 102; preferably, on the back panel side 1012 of the display module 101, the distance d1 between the edge of the second fixed structure 104 away from the middle frame 102 and the edge of the first fixed structure 103 away from the middle frame 102 is in the range of 0.05-0.1 mm.

[0037] Specifically, the first fixing structure 103 covers the edge area of ​​the display module 101, that is, the first fixing structure 103 tightly surrounds the edge of the display module 101, providing direct fixation and protection for the display module 101. The second fixing structure 104 covers part or all of the surface of the first fixing structure 103, providing support and further fixation, and ensuring the stability of the display module 101.

[0038] For example, on the display side 1011 of the display module 101, the second fixing structure 104 partially covers the first fixing structure 103. Figure 3, on the display side 1011 of the display module 101, the edge of the second fixed structure 104 is close to the side of the middle frame 102 relative to the edge of the first fixed structure 103. The distance d1 between the edge of the second fixed structure 104 away from the middle frame 102 and the edge of the first fixed structure 103 away from the middle frame 102 ranges from 0.05 to 0.1 mm. Exemplarily, the distance d1 between the edge of the second fixed structure 104 away from the middle frame 102 and the edge of the first fixed structure 103 away from the middle frame 102 can be set to 0.05 mm, 0.06 mm or 0.09 mm. Exemplarily, on the back panel side 1012 of the display module 101, the second fixed structure 104 partially covers the first fixed structure 103. On the back panel side 1012 of the display module 101, the edge of the second fixed structure 104 is close to the side of the middle frame 102 relative to the edge of the first fixed structure 103. The distance d1 between the edge of the second fixed structure 104 away from the middle frame 102 and the edge of the first fixed structure 103 away from the middle frame 102 ranges from 0.05 to 0.1 mm. Exemplarily, the distance d1 between the edge of the second fixed structure 104 away from the middle frame 102 and the edge of the first fixed structure 103 away from the middle frame 102 can be set to 0.06 mm, 0.08 mm or 0.1 mm. The preferred distance range is that the existing manufacturing process can accurately control and achieve, and ensures that the fixed structures do not interfere with each other when folded, while providing sufficient support and fixing.

[0039] In this embodiment, the first fixing structure 103 tightly covers the edge of the display module 101, and the second fixing structure 104 covers the first fixing structure 103, forming a multi-level protection mechanism, which effectively enhances the fixation and protection of the display module 101. In addition, this embodiment provides a preferred width range of the second fixing structure 104 covering the first fixing structure 103, which is conducive to further reducing the border width of the display device 100.

[0040] Figure 4 FIG. 2 is a schematic diagram of the structure of a display device provided by another embodiment of the present application. Figure 4As shown, on the display side 1011 and / or the back panel side 1012 of the display module 101, the thickness d2 of the first fixing structure 103 is less than or equal to 0.05 mm; preferably, in the direction x from the middle frame 102 to the display module 101, the thickness d3 of the first fixing structure 103 ranges from 0.3 to 0.5 mm; preferably, on the display side 1011 and / or the back panel side 1012 of the display module 101, the thickness d4 of the second fixing structure 104 ranges from 0.2 to 0.25 mm; preferably, on the display side of the display module and / or the back panel side, the thickness range of the fixed structure is 0.25-0.3 mm; preferably, in the direction x pointing from the middle frame 102 to the display module 101, the thickness d5 of the second fixed structure 104 is greater than 0.2 mm; preferably, on the display side 1011 of the display module 101, the width d6 of the display module 101 covered by the first fixed structure 103 is greater than 0.5 mm; preferably, on the back panel side 1012 of the display module 101, the width d6 of the display module 101 covered by the first fixed structure 103 is greater than 0.5 mm.

[0041] Specifically, see Figure 4 , on the display side 1011 and / or the back panel side 1012 of the display module 101, the thickness d2 of the first fixed structure 103 is less than or equal to 0.05 mm. Exemplarily, the thickness d2 of the first fixed structure 103 can be set to 0.01 mm, 0.03 mm or 0.04 mm. This thickness range ensures that the first fixed structure 103 has both a certain strength and sufficient flexibility to adapt to the folding operation. In the direction x from the middle frame 102 to the display module 101, the thickness d3 of the first fixed structure 103 ranges from 0.3 to 0.5 mm. Exemplarily, the thickness d3 of the first fixed structure 103 can be set to 0.35 mm, 0.45 mm or 0.5 mm. This thickness range ensures that the first fixed structure 103 provides sufficient protection for the display module 101, conforms to the existing manufacturing process, is easy to implement and maintains consistency, is conducive to maintaining the thinness of the display device 100, and improves the user experience.

[0042] On the display side 1011 and / or the back panel side 1012 of the display module 101, the thickness d4 of the second fixed structure 104 ranges from 0.2 to 0.25 mm. Exemplarily, the thickness d4 of the second fixed structure 104 can be set to 0.2 mm, 0.22 mm or 0.25 mm. In the direction x from the middle frame 102 to the display module 101, the thickness d5 of the second fixed structure 104 is greater than 0.2 mm. Exemplarily, the thickness d5 of the second fixed structure 104 can be set to 0.25 mm, 0.45 mm or 0.5 mm. The second fixed structure 104 is thicker than the first fixed structure 103 and can provide a stronger support. Exemplarily, on the display side 1011 and / or the back panel side 1012 of the display module 101, the thickness d8 of the fixed structure ranges from 0.25 to 0.3 mm. The thickness can be adjusted by adjusting the thickness of the first fixed structure 103 and the second fixed structure 104, respectively, to ensure the functionality of the fixed structure.

[0043] On the display side 1011 of the display module 101, the width d6 of the first fixing structure 103 covering the display module 101 is greater than 0.5 mm, which can ensure that the first fixing structure 103 provides sufficient protection at the edge of the display module 101. On the back panel side 1012 of the display module 101, the width d6 of the first fixing structure 103 covering the display module 101 is also greater than 0.5 mm. It can ensure that the first fixing structure 103 provides uniform fixation and protection on the back panel side 1012. Exemplarily, the width d6 of the first fixing structure 103 covering the display module 101 can be set to 0.55 mm, 0.6 mm or 0.75 mm.

[0044] For example, Figure 5 FIG. 2 is a schematic diagram of the structure of a display device provided by another embodiment of the present application. Figure 5 As shown, in the direction y from the back panel side 1012 of the display module 101 to the display side 1011, the display module 101 includes a copper foil 1016, a display panel 1015, a polarizer 1014 and a cover plate 1013. Specifically, the width d7 of the first fixing structure 103 covering the copper foil 1016 is greater than 0.5 mm.

[0045] In this embodiment, the preferred thickness (or width) range of the first fixing structure 103 and the second fixing structure 104 covering the edge area of ​​the display module 101 is given, ensuring that the first fixing structure 103 has sufficient strength to fix and protect the display module 101 while maintaining flexibility; and ensuring that the second fixing structure 104 can provide strong support to protect the display module 101 from being easily damaged when subjected to external pressure. This arrangement further reduces the frame width of the display device 100, ensures that the edge of the display module 101 is evenly protected, reduces the risk of edge damage, and further helps to improve the reliability of the display device 100.

[0046] Figure 6 FIG. 2 is a schematic diagram of the structure of a display device provided by another embodiment of the present application. Figure 6 As shown, the first fixing structure 103 covers the edge area of ​​the display module 101 ; in the direction y from the back panel side 1012 of the display module 101 to the display side 1011 , the second fixing structure 104 is located on the side of the first fixing structure 103 away from the display module 101 .

[0047] Specifically, the first fixed structure 103 covers the edge area of ​​the display module 101, providing direct fixation and protection for the display module 101. In the direction y from the back panel side 1012 of the display module 101 to the display side 1011, the second fixed structure 104 is arranged on the side of the first fixed structure 103 away from the display module 101, which can provide fixation and protection for the display module 101. In the direction x from the middle frame 102 to the display module 101, the two sides of the first fixed structure 103 are in direct contact with the middle frame 102 and the display module 101 respectively. This arrangement further enhances the flexibility of the fixed structure to adapt to the folding operation. The technical solution of this embodiment is conducive to further reducing the border width of the display device 100 and improving the reliability of the display device 100.

[0048] Figure 7 FIG. 2 is a schematic diagram of the structure of a display device provided by another embodiment of the present application. Figure 7 As shown, the first fixed structure 103 covers the side surface of the display module 101 and a portion of the back surface of the display module 101; in the direction y from the back panel side 1012 of the display module 101 to the display side 1011, the second fixed structure 104 is located on one side of the first fixed structure 103, and the second fixed structure 104 covers a portion of the surface of the display module 101 located on the display side 1011.

[0049] Specifically, the difference between this embodiment and the above-mentioned embodiments is that the first fixing structure 103 only covers the side and part of the back of the display module 101, while the second fixing structure 104 covers part of the surface of the display module 101 located on the display side 1011. The cover plate 1013 located on the display side 1011 of the display module 101 usually remains stable when the display device 100 is folded or unfolded, and does not interfere with the middle frame 102. Therefore, the first fixing structure 103 is not provided on the light-emitting surface, but the second fixing structure 104 is provided to enhance the strength of the screen structure, which is further conducive to the display device 100 to achieve lightness and thinness. Moreover, in the direction x from the middle frame 102 to the display module 101, the two sides of the first fixing structure 103 are in direct contact with the middle frame 102 and the display module 101 respectively to adapt to the folding operation. Therefore, the technical solution of this embodiment is conducive to further reducing the frame width of the display device 100 and improving the reliability of the display module 101.

[0050] Figure 8 FIG. 2 is a schematic diagram of the structure of a display device provided by another embodiment of the present application. Figure 8 As shown, the first fixed structure 103 includes a first part 1031 and a second part 1032 which are arranged at intervals, the first part 1031 is located on the back panel side 1012 of the display module 101, the second part 1032 is located on the display side 1011 of the display module 101, and the second fixed structure 104 is arranged around the display module 101, the second fixed structure 104 covers the surface of the first part 1031 away from the display module 101, and the second fixed structure 104 covers the surface of the second part 1032 away from the display module 101; preferably, the surface of the second fixed structure 104 facing the display module 101, the surface of the first fixed structure 103 facing the second fixed structure 104, and the side of the display module 101 are surrounded to form a cavity 106.

[0051] Specifically, the first portion 1031 is located on the back panel side 1012 of the display module 101, and the first portion 1031 covers a portion of the back surface of the display module 101. The second portion 1032 is located on the display side 1011 of the display module 101, and the second portion 1032 covers a portion of the light emitting surface of the display module 101. The second fixing structure 104 is disposed around the display module 101, and covers two portions of the surface of the first fixing structure 103 that are away from the display module 101, and together with the first fixing structure 103, provides protection for the display module 101 in layers.

[0052] The surface of the second fixing structure 104 facing the display module 101, the surface of the first fixing structure 103 facing the second fixing structure 104, and the side of the display module 101 are together formed to form a cavity 106, which is conducive to optimizing structural strength and reducing weight. Exemplarily, the cross-sectional shape of the cavity 106 is semicircular. Of course, the cross-sectional shape of the cavity 106 can also be other regular or irregular shapes, and this application does not make specific restrictions on this.

[0053] The technical solution of this embodiment provides direct fixation and protection for the display module 101 by dividing the first fixing structure 103 into two parts and covering the edge areas of the two opposite surfaces of the display module 101. The second fixing structure 104 covers the surface of the first fixing structure 103, providing double protection for the display module 101 and reducing the risk of damage caused by external impact or pressure. The design of the cavity 106 is conducive to better distribution of stress during the folding or bending operation of the display device 100, reducing direct pressure on the display module 101, thereby reducing the possibility of damage.
