[0072] In this embodiment, the adapter frame is arranged between the back plate and the display panel as a component of the display module, and is connected to the external support structure of the display module. In this way, on the one hand, the adapter frame can occupy less assembly space, and on the other hand, the adapter frame in the display module can achieve more reliable external and internal support. In addition, compared with the method of installing the base adapter frame on the entire outside of the display device in the related art, this embodiment can save the installation of the external adapter frame of the display device, thereby saving related labor costs.

[0073] refer to Figure 1 In some embodiments, the back panel 10 may have a first edge extending along a first direction s and a second edge extending along a second direction r. The adapter frame 30 is located inside the corner where the first edge and the second edge intersect. The first direction s and the second direction r may form a preset angle with each other, for example, a 90-degree angle, that is, the first direction s is perpendicular to the second direction r, thereby forming a right-angled corner.

[0074] exist Figure 1 In the embodiment, the back plate 10 is rectangular in shape as a whole, and has a first edge 12 on the left and right sides and a second edge 13 on the upper and lower sides.

In other embodiments, two adapter frames 30 may also be arranged at the two corners respectively formed by the second edge 13 on the upper side and the first edges 12 on the left and right sides for connection with an external support structure.

[0075] exist Figure 1In the embodiment, the display module 40 may further include a first frame 41 and a second frame 42. The first frame 41 may be disposed at the first edge of the back plate 10, and may position and protect the back plate 10, the adapter frame 30, the display panel 43, and other structures between the back plate 10 and the display panel 43 on the left and right sides of the display module. The second frame 42 may be disposed at the second edge of the back plate 10, and may support and protect the back plate 10, the adapter frame 30, the display panel 43, and other structures between the back plate 10 and the display panel 43 on the lower side and the front side of the display module.

[0076] refer to Figure 3 In some embodiments, the display module 40 may further include other structures between the display panel 43 and the back plate 10. For example, when a liquid crystal display panel is used as the display panel 43, the display module 40 may further include devices for realizing backlight, such as a reflective paper 44, a light bar, an optical film layer 45, and a printed circuit board (PCB) holder 46. The reflective paper 44 is located between the adapter 30 and the display panel 43, and is supported by the adapter 30, which can realize the function of the bottom reflective layer. The light bar can be located at the outer edge of the plane of the optical film layer 45 to provide a side-entry light source to the optical film layer. The optical film layer 45 is located between the display panel 43 and the reflective paper 44, and can realize functions such as light guiding, light homogenization, and light focusing as needed. The PCB holder 46 is located between the reflective paper 44 and the back plate 10, and is arranged adjacent to the second frame 42, and can be used to hold the PCB board of the display module 40.

[0077] Figure 4A and Figure 4B They are schematic diagrams of the three-dimensional structure of an adapter frame in one embodiment of a display module according to the present disclosure from front and rear perspectives. Figure 5A It is a schematic diagram of a cross section of an assembly structure of a display module according to an embodiment of the present disclosure along a direction parallel to a first direction and perpendicular to a back plate. Figure 5B yes Figure 5A Schematic diagram of the partial cross-sectional structure of the . Figure 6 and Figure 7 They are partial schematic diagrams of the assembly structure of an embodiment of a display module according to the present disclosure and a fixed base at a forward viewing angle and a downward viewing angle, respectively.

[0078] refer to Figure 2 The external support structure on the side of the back plate 10 away from the display panel 43 may include a wall-mounted structure. The wall-mounted structure may include a mounting plate 80 corresponding to the middle of the back plate 10 and wall mounts 60 located on the left and right sides of the mounting plate 80. The mounting plate 80 may be provided with a plurality of connection holes for fixing the connection parts for mounting, such as screws, etc. In cooperation with this, Figure 1A plurality of hooking holes 11 for hooking and matching with the connecting piece may also be provided in the middle of the middle back plate 10. The cross-sectional shape of the hooking hole 11 may be set to a circle with two intersecting boundaries, and the diameter of the circle located on the sky side is smaller than the diameter of the circle located on the ground side, so that the connecting piece fixed on the hooking plate 80 can enter from the part of the hooking hole 11 corresponding to the circular cross section on the ground side, and be hooked on the part of the hooking hole 11 corresponding to the circular cross section on the sky side.

[0079] refer to Figure 4A , Figure 5A and Figure 5B In some embodiments, the adapter frame 30 includes: a first frame 31 and a plurality of mounting grooves 38. The first frame 31 is arranged adjacent to the first edge along the first direction s, and the plurality of mounting grooves 38 are located on a side of the first frame 31 adjacent to the display panel 43. The display module 40 may include a plurality of magnetic bodies 50. The plurality of magnetic bodies 50 are respectively arranged in the plurality of mounting grooves 38 along the first direction s, and can adsorb the wall mount 60 by magnetic force.

[0080] The wall mount 60 can be made of ferromagnetic metal (such as iron, nickel, cobalt, etc.) or alloy. The magnetic body 50 can be a magnet, etc. The adapter 31 can be made of non-ferromagnetic metal or non-metallic material to avoid affecting the adsorption effect of the magnetic body 50 on the wall mount 60. When multiple magnetic bodies 50 are arranged in the mounting groove 38 at intervals along the first direction s, the multiple magnetic bodies 50 can simultaneously form a more stable and reliable adsorption effect on the wall mount 60 located on the side of the back plate away from the display panel.

[0081] exist Figure 4A and Figure 4B In the embodiment, the first frame 31 may be in a straight strip shape along the first direction s so as to occupy less space in the second direction r. The plurality of mounting grooves 38 may be formed by crossing a plurality of reinforcing ribs. Figure 4A In some embodiments, the adapter frame 30 further includes: a plurality of first reinforcing ribs 33 and a plurality of second reinforcing ribs 34. The plurality of first reinforcing ribs 33 are located on the surface of the first frame body 31 and extend along the first direction s, and the plurality of second reinforcing ribs 34 are located on the surface of the first frame body 31 and extend along the second direction r. The plurality of second reinforcing ribs 34 cross and connect with the plurality of first reinforcing ribs 33 to form the plurality of mounting grooves 38. The mutually crossed first reinforcing ribs 33 and second reinforcing ribs 34 can effectively improve the strength and rigidity of the first frame body 31.

[0082] refer to Figure 4AThe second surface B of the adapter frame 30 includes the end surface of the plurality of second reinforcing ribs 34 adjacent to the display module 40 and the end surface of the plurality of first reinforcing ribs 33 adjacent to the display module 40. The end surface of the plurality of second reinforcing ribs adjacent to the display module and the end surface of the plurality of first reinforcing ribs adjacent to the display module can be located in the same plane. The plane can be at an acute angle with the surface of the back plate 10 along the second direction r, and can support the portion of the reflective paper 44 close to the first frame 41 on both sides to prevent the reflective paper from collapsing. The middle part of the reflective paper 44 is supported by the back plate surface, while the portion of the reflective paper close to the first edge of the back plate is tilted and bent relative to the middle part toward the display panel, so as to obtain a lateral reflection effect.

[0083] The adapter frame 30 of this embodiment can not only support the display module by connecting with the external support structure of the display module, but also support the reflective paper inside the display module. Compared with the base adapter frame outside the display device in the related art, this embodiment reasonably arranges the spatial structure through the adapter frame, reduces redundant structural components, saves costs, and is more concise in structure, occupies less space, thereby obtaining a thinner display device.

[0084] In order to determine the relative position between the adapter frame 30 and the first frame 41 during assembly, refer to Figure 1 , Figure 4A and Figure 4B In some embodiments, the adapter frame 30 may further include a limit block 39. The limit block 39 is disposed on the first frame body 31 and protrudes relative to the first frame body 31 along the second direction r toward the first edge. The limit block 39 may be engaged with the first frame 41 to limit the relative position of the adapter frame 30 and the first frame 41. Figure 4A and Figure 4B In some embodiments, a limiting hole may be provided in the limiting block 39, and a protrusion may be provided at a position of the first frame 41 corresponding to the limiting block 39, and the protrusion may be inserted into the limiting hole to achieve the clamping fixation of the two. After the first frame and the back plate are assembled, the clamping position of the limiting block and the first frame may be used to position the adapter frame 30, thereby improving the assembly accuracy of the adapter frame 30.

[0085] refer to Figure 3-5B In some embodiments, the adapter frame 30 may further include: a second frame 32. The second frame 32 is connected to the first frame 31 and is arranged adjacent to the second edge along the second direction r. The second frame 32 may abut against the second frame 42. Figure 4A and Figure 4BIn the embodiment, the second frame 32 may be in a straight strip shape along the second direction r, thereby forming an L shape with the first frame 31, and the right-angled portion of the L shape at least partially fits with the right-angled corner of the back panel, thereby supporting and protecting the corner of the back panel.

[0086] exist Figure 4B In the embodiment, the first surface A of the adapter frame 30 is a plane, so that the surface of the back plate forms a larger surface contact relationship, so that the adapter frame 30 and the back plate can be more firmly combined. The first surface A may include a surface of the first frame body 31 adjacent to the back plate and a surface of the second frame body 32 adjacent to the back plate that are seamlessly connected.

[0087] refer to Figure 4A-Figure 5B A mounting groove 37 for mounting with the wall mount 60 may be provided on the end surface of the second frame 32 away from the first frame 31. Figure 5A and Figure 5B In the figure, a U-shaped bend 61 can be formed at the bottom of the wall bracket 60, and the U-shaped bend 61 can be inserted into the hanging groove 37 from the end surface of the second frame body 32 away from the first frame body 31. In this way, together with the adsorption effect of multiple magnetic bodies 50 on the wall bracket 60, a more stable and reliable connection and support relationship can be formed between the adapter frame 30 and the wall bracket 60.

[0088] exist Figure 4A In the embodiment, the orthographic projections of the multiple magnetic bodies 50 on the end face of the second frame 32 away from the first frame 31 can be at least partially overlapped with the orthographic projections of the hanging grooves 37 on the end face, especially within the orthographic projections of the hanging grooves 37 on the end face. This can ensure that the hanging force between the adapter frame 30 and the wall bracket 60 is consistent with the friction force generated by the adsorption force of the magnetic bodies 50 on the wall bracket 60, thereby further improving the supporting effect.

[0089] In order to form the hanging groove 37, a protruding structure 37a protruding toward the display panel can be formed on the second frame 32, and the hanging groove 37 is formed in the protruding structure 37a. The protruding structure 37a is connected to the portion of the first frame 31 adjacent to the second frame through a reinforcing rib 37b to improve the connection strength and rigidity between the first frame 31 and the second frame 32.

[0090] refer to Figure 4A , Figure 4B , Figure 6 and Figure 7 In some embodiments, the external support structure may include a bottom support seat 70, and a mounting hole group may be provided on the end surface of the second frame 32 away from the first frame 31 (i.e., the end surface adjacent to the second edge). The mounting hole group includes at least two mounting holes 36 for connecting to the bottom support seat 70. The mounting holes 36 may be fixedly connected to the bottom support seat 70 by a connecting member (such as a screw, etc.). Figure 6 and Figure 7 In the embodiment, the bottom support frame 70 can achieve an overall supporting function for the display module 40 through the fixed connection between the mounting hole 36 and the bottom support frame 70 .

[0091] exist Figure 7 In the embodiment, the bottom support frame 70 may include a connecting portion 71 and two supporting portions 72. The connecting portion 71 may abut against the second frame 42 and have a connecting structure, such as a through hole, that cooperates with at least two mounting holes 36. The two supporting portions 72 are fixedly connected to the connecting portion 71, and the two supporting portions 72 may be at a preset angle, such as 90 degrees or 120 degrees, to each other. For the display module 40, the left and right corners thereof may be supported by two bottom support frames 70 respectively, and the two supporting portions 72 are located on a side away from the display module 40 relative to the connecting portion 71.

[0092] refer to Figure 4A , Figure 4B and Figure 7 , at least two mounting holes 36 may be spaced apart along the second direction r. The mounting holes may be threaded holes that can be threadedly matched with screws. At least two mounting holes 36 may be located in the same straight line. For more than three mounting holes 36, they may also be located in different straight lines to form a more stable support surface. Figure 4A , Figure 4B and Figure 7 In the embodiment, at least two mounting holes 36 are three mounting holes 36, and the connecting lines of the three mounting holes 36 form an obtuse triangle. In this way, a more stable triangular support can be formed, and the width of the obtuse triangle in the direction perpendicular to the back plate occupies less space, meeting the installation requirements of a thinner display module.

[0093] Since the second frame 32 needs to form a supporting function with at least one of the bottom support frame 70 and the wall bracket 60, in order to improve the structural strength and rigidity of the second frame 32 itself, refer to Figure 4A In some embodiments, the adapter frame 30 may further include a plurality of third reinforcing ribs 35. The plurality of third reinforcing ribs 35 are located on the surface of the second frame body 32 and extend along the first direction s. At least part of the plurality of third reinforcing ribs 35 may be located between each two adjacent mounting holes 36 of the at least two mounting holes 36.

[0094] To form at least two mounting holes 36, at least two protruding structures 36a protruding toward the display panel may be formed on the second frame 32, and a mounting hole 36 may be formed in each protruding structure 36a. The third reinforcing rib 35 may be located between two adjacent protruding structures 36a.

[0095] The embodiments of the display module disclosed above can be applied to various display devices. Accordingly, the present disclosure also provides a display device, including any embodiment of the display module described above. The display device can be a display, a television, etc.
