The backlight module and the diffuser can be arranged at intervals on the back panel, and the light-emitting side of the backlight module faces the diffuser so that the light from the backlight module is evenly scattered through the diffuser to improve the display effect and visual comfort of the display module. However, the connection between the diffuser and the back panel is unstable, and the diffuser is prone to offset. Utility Model Content

[0003] The embodiments of the present application provide a display device, which can solve the technical problems that the connection between the diffusion plate and the back plate is unstable and the diffusion plate is prone to deviation.

[0005] The back plate comprises a main body, a connecting portion and a frame connected to each other; the connecting portion is arranged around the outside of the main body, the outer surface of the connecting portion is connected to the frame, and the frame extends toward the front side of the main body;

[0006] A backlight module is arranged at the front side of the main body, and a light emitting side of the backlight module faces the front side of the main body;

[0007] A connecting member is arranged on the surface of the connecting portion away from the main body; the surface of the connecting member facing the connecting portion has a fitting surface, and the fitting surface is at least used to fit with the surface of the connecting portion away from the main body; the surface of the connecting member away from the connecting portion has an abutting surface;

[0008] A diffusion plate, wherein the first portion of the diffusion plate is arranged parallel to and opposite to the backlight module, the second portion of the diffusion plate abuts against the abutting surface, and the area of ​​the second portion of the diffusion plate is larger than the area of ​​the portion of the diffusion plate parallel to and opposite to the connecting portion.

[0009] In the display device of the embodiment of the present application, the backlight module and the diffuser are arranged on the front side of the main body, and the light-emitting side of the backlight module faces the first part of the diffuser so as to evenly scatter the light from the backlight module through the diffuser. The connector can be arranged on the surface of the connecting part away from the main body, and the surface of the connecting part away from the connecting part has an abutting surface, and the abutting surface abuts against the second part of the diffuser, so that the second part of the diffuser can be fixed to the connecting part through the connector.

[0010] In the related art, the diffuser plate directly abuts against the connection part, and the contact area between the diffuser plate and the connection part is equal to the area of ​​the parallel opposite parts of the diffuser plate and the connection part. In the embodiment of the present application, at least part of the abutting surface can be located on the inner side of the connection part, so that the area of ​​the second part of the diffuser plate can be increased, so that the area of ​​the second part of the diffuser plate is larger than the area of ​​the parallel opposite parts of the diffuser plate and the connection part, so that the contact area of ​​the diffuser plate can be increased, the stability of the connection between the diffuser plate and the back plate can be improved, and the possibility of the diffuser plate being offset can be reduced.

[0011] In some embodiments of the present application, at least a portion of the abutment surface is located on the inner side of the connecting portion;

[0012] In the direction close to the frame, the edge of the abutting surface is flush with the edge of the diffuser plate; or, in the direction close to the frame, the distance between the edge of the abutting surface and the frame is smaller than the distance between the edge of the diffuser plate and the frame.

[0013] In this way, when the edge of the abutting surface is flush with the edge of the diffuser plate, it can ensure parallel alignment between the abutting surface and the diffuser plate in the direction close to the frame, increase the contact area between the diffuser plate and the abutting surface of the connector, and improve the stability of the connection between the diffuser plate and the connector.

[0014] Alternatively, when the distance between the edge of the abutting surface and the frame is smaller than the distance between the edge of the diffuser plate and the frame, not only can the contact area between the diffuser plate and the abutting surface of the connecting piece be increased, thereby improving the stability of the connection between the diffuser plate and the connecting piece, but also the gap between the diffuser plate and the frame can be effectively reduced, thereby improving the firmness and stability of the connection between the diffuser plate and the back panel.

[0015] In some embodiments of the present application, taking a plane parallel to the diffuser plate as a cross section, the cross-sectional area of ​​the connector gradually increases in a direction from the fitting surface to the abutting surface.

[0016] With such arrangement, the surface of the connecting piece facing the connecting portion has a fitting surface for fitting with the surface of the connecting portion facing away from the main body, thereby improving the stability and firmness of the connection between the connecting piece and the connecting portion.

[0017] In the case of a plane parallel to the diffuser plate as a cross section, the cross-sectional area of ​​the connector gradually increases from the fitting surface to the abutting surface, thereby increasing the contact area between the connector and the diffuser plate and improving the stability of the connection between the diffuser plate and the connector.

[0019] A fixing piece is arranged in the fixing groove, and the connecting piece is fixed relative to the connecting portion through the fixing piece.

[0020] In this arrangement, by providing a fixing groove on the connecting piece, the notch of the fixing groove faces the diffuser plate, and a fixing piece is provided in the fixing groove, thereby reducing the interference of the fixing piece on the diffuser plate, and also allowing the connecting piece to be relatively fixed to the connecting part through the fixing piece, thereby ensuring the stability and firmness of the connection.

[0021] Furthermore, by providing the fixing groove and the fixing piece, the fixing between the connecting piece and the connecting portion is made simpler and more effective, thereby improving the installation efficiency of the connecting piece.

[0022] In some embodiments of the present application, the fixing member is configured as a fixing bolt;

[0023] The nut of the fixing bolt is located in the fixing groove, the threaded section of the fixing bolt passes through the connecting piece, and the threaded section of the fixing bolt is threadedly connected to the connecting part.

[0024] In this arrangement, by configuring the fixing member as a fixing bolt, the nut is located in the fixing groove, the threaded section passes through the connecting member, and the threaded section is threadedly connected to the connecting part, thereby ensuring the stability and firmness of the connection.

[0025] Furthermore, by providing the fixing member as a fixing bolt, the fixation between the connecting member and the connecting portion is made more flexible, so that the position and tightness of the connecting member can be adjusted by threaded connection.

[0061] As described in the background technology, the display device in the related art may include a back plate, a backlight module and a diffusion plate, and the back plate may include a main body, a connecting portion and a frame connected to each other. The connecting portion may be arranged around the outside of the main body, and the outer surface of the connecting portion is connected to the frame, and the frame extends toward the front side of the main body. The backlight module may be arranged on the front side of the main body, and the diffusion plate may be connected to the connecting portion, so that the backlight module and the diffusion plate may be arranged at intervals, and the light-emitting side of the backlight module faces the diffusion plate, so as to evenly scatter the light from the backlight module through the diffusion plate, thereby improving the display effect and visual comfort of the display module.

[0062] However, due to the limitations of the backplane size and the arrangement of the lamp beads in the display module, for example, in a high-partition miniLED (i.e., mini Light Emitting Diode) display module, the distance between the outer lamp beads and the display area is small, which makes the width of the connection part small, and the contact area between the diffuser plate and the connection part is small, making the connection between the diffuser plate and the backplane unstable, and the diffuser plate is prone to offset, etc. In addition, since the support area of ​​the connection part for the diffuser plate is small, the diffuser plate is prone to collapse, etc., thereby affecting the stability of the diffuser plate.

[0063] In view of this, in the display device of the embodiment of the present application, the backlight module and the diffuser are arranged on the front side of the main body, and the light-emitting side of the backlight module faces the first part of the diffuser so as to evenly scatter the light from the backlight module through the diffuser. The connecting member can be arranged on the surface of the connecting part away from the main body, and the surface of the connecting member away from the connecting part has an abutting surface, and the abutting surface abuts against the second part of the diffuser, so that the second part of the diffuser can be fixed to the connecting part through the connecting member.

[0064] In the related art, the diffuser plate directly abuts against the connection part, and the contact area between the diffuser plate and the connection part is equal to the area of ​​the parallel opposite parts of the diffuser plate and the connection part. In the embodiment of the present application, at least part of the abutting surface can be located on the inner side of the connection part, so that the area of ​​the second part of the diffuser plate can be increased, so that the area of ​​the second part of the diffuser plate is larger than the area of ​​the parallel opposite parts of the diffuser plate and the connection part, so that the contact area and support area of ​​the diffuser plate can be increased, the possibility of collapse of the diffuser plate can be reduced, the stability of the connection between the diffuser plate and the back plate can be improved, and the possibility of deviation of the diffuser plate can be reduced.

[0071] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions 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 are within the scope of protection of this application.

[0072] Reference Figure 1-Figure 3 The embodiment of the present application provides a display device, including a back plate 100 and a display module. The backlight side of the display module faces the back plate 100, and the light-emitting side of the display module faces the front side of the back plate 100. The back plate 100 can at least be used to support and protect the display module, reducing the possibility of deformation and damage of the display module.

[0073] In some possible implementations, the back plate 100 may be made of metal, plastic or other materials. The back plate 100 has good strength and stability to ensure the stability and durability of the overall structure of the display device.

[0074] Reference Figure 2 and Figure 3 Exemplarily, the back plate 100 may include a main body 110 . The main body 110 may serve as a main overall structure of the back plate 100 , and the back plate 100 may support and fix the backlight module 300 through the main body 110 .

[0075] For example, the front side of the main body 110 may be connected to the backlight module 300 so that the light emitting side of the backlight module 300 faces the front side of the main body 110 and the light emitting direction of the backlight module 300 faces away from the main body 110 .

[0076] The back plate 100 may include a connection portion 120 and a frame 130. The connection portion 120 may be disposed around the outside of the main body 110, and the outer surface of the connection portion 120 may be connected to the frame 130. The frame 130 may be fixed to the back plate 100 through the connection portion 120, and the frame 130 may extend toward the front side of the main body 110.

[0077] The connection part 120 can be arranged parallel to the display module. In the thickness direction of the display module, the connection part 120 can be arranged on the light-emitting side of the display module. The surface of the connection part 120 away from the display module can at least be used to connect to the diffuser plate 200 and other structures, so that the diffuser plate 200 can be arranged parallel to the display module.

[0078] Exemplarily, the display device may include a connector 400. The connector 400 may be disposed on a surface of the connector 120 that faces away from the body 110. The surface of the connector 400 that faces away from the connector 120 may have an abutment surface 440, at least part of which is located inside the connector 120.

[0079] The display device may include a diffuser plate 200. The diffuser plate 200 may be fixed relative to the connection portion 120 via a connector 400. The first portion of the diffuser plate 200 is arranged parallel to and opposite to the backlight module 300, so that the diffuser plate 200 evenly scatters the light from the backlight module 300, thereby improving the display effect and visual comfort of the display module.

[0080] Exemplarily, the second portion of the diffuser plate 200 may abut against the abutting surface 440 of the connector 400 to support and fix the diffuser plate 200 via the abutting surface 440 , and the area of ​​the second portion of the diffuser plate 200 may be larger than the area of ​​the portion of the diffuser plate 200 parallel to the connecting portion 120 .

[0081] It should be noted that, in the related art, the diffuser plate 200 directly contacts the connection portion 120 , and the contact area between the diffuser plate 200 and the connection portion 120 is equal to the area of ​​the parallel opposing portions of the diffuser plate 200 and the connection portion 120 .

[0082] In the embodiment of the present application, at least a portion of the abutment surface 440 can be located on the inner side of the connecting portion 120, thereby increasing the area of ​​the second portion of the diffuser plate 200, so that the area of ​​the second portion of the diffuser plate 200 is larger than the area of ​​the parallel relative portions of the diffuser plate 200 and the connecting portion 120, thereby increasing the contact area and support area of ​​the diffuser plate 200, reducing the possibility of collapse of the diffuser plate 200, improving the stability of the connection between the diffuser plate 200 and the back plate 100, and reducing the possibility of deviation of the diffuser plate 200.

[0083] In some possible embodiments, at least two of the main body 110, the connecting portion 120 and the frame 130 in the back panel 100 may be integrally formed by stamping or the like, so as to make the structure of the back panel 100 more stable, reduce the possibility of deformation of the back panel 100, and improve the stability of the support and connection of the back panel 100 to the display module and the diffuser plate 200.

[0084] Exemplarily, the back panel 100 may be formed by splicing a plurality of components to facilitate the formation process of the back panel 100 . For example, at least two of the main body 110 , the connecting portion 120 and the frame 130 in the back panel 100 may be connected and fixed by splicing or the like.

[0085] For example, the display device may have a top side and a bottom side that are arranged opposite to each other, and a left side and a right side that are arranged opposite to each other. The back plate 100 may include four parts that are spliced ​​and fixed to each other, and the four parts may be located at the top side of the display device, the bottom side of the display device, the left side of the display device, and the right side of the display device, respectively, so as to make the formation process of the back plate 100 more convenient.

[0086] When the display device is placed in a vertical direction, the sky side of the display device is set as the side of the display device facing upward, the ground side of the display device is set as the side of the display device facing downward, the left side of the display device is set as the side of the display device facing left, and the right side of the display device is set as the side of the display device facing right.

[0087] Reference Figure 4 and Figure 5 ,as well as Figure 6 and Figure 7 In some possible implementations, the connector 400 may be detachably connected to the connecting portion 120. By detachably connecting the connector 400 to the connecting portion 120, the connection between the connector 400 and the connecting portion 120 may be more flexible and convenient to disassemble.

[0088] Furthermore, by detachably connecting the connector 400 to the connecting portion 120, different diffuser plates 200 can be installed on the back panel 100 by replacing connectors 400 of different specifications and models, so that the back panel 100 can be adapted to different diffuser plates 200, thereby improving the scope of application of the back panel 100 and improving the interoperability of the back panel 100.

[0089] For example, refer to Figure 8 and Fig. 9 ,as well as Fig.10 and Fig.11 When the distance between the diffuser plate 200 and the display module changes, connectors 400 of different specifications can be installed on the connecting portion 120, so that the distance between the abutting surface 440 and the connecting portion 120 in the thickness direction of the display module can be adjusted, so that the distance between the diffuser plate 200 and the display module can be changed by adjusting the connector 400, making the back plate 100 more widely used.

[0090] Exemplarily, the surface of the connector 400 facing the connecting portion 120 may have a fitting surface 450 , which can at least be used to fit with the surface of the connecting portion 120 facing away from the main body 110 , thereby improving the stability and firmness of the connection between the connector 400 and the connecting portion 120 .

[0091] Taking the plane parallel to the diffuser 200 as the cross section, the cross-sectional area of ​​the connector 400 can be gradually increased in the direction from the fitting surface 450 to the abutting surface 440. This arrangement can increase the contact area between the connector 400 and the diffuser 200 and improve the stability of the connection between the diffuser 200 and the connector 400.

[0092] The connector 400 may be an annular connector 400 . The annular connector 400 may be disposed inside the frame 130 , with the outer side of the annular connector 400 facing the inner surface of the frame 130 , and the inner side of the annular connector 400 facing away from the inner surface of the frame 130 .

[0093] The annular connecting member 400 may be integrally formed to make the structure of the annular connecting member 400 more stable.

[0094] Alternatively, the annular connector 400 may include four parts that are spliced ​​and fixed to each other, and the four parts may be respectively located on the sky side of the display device, the ground side of the display device, the left side of the display device, and the right side of the display device, so as to make the formation process of the annular connector 400 more convenient.

[0095] It is easy to understand that the connecting portion 120 may include four parts that are spliced ​​and fixed to each other. The four parts may be respectively located on the sky side of the display device, the ground side of the display device, the left side of the display device, and the right side of the display device. Each part may be set as a strip-shaped connecting portion 120.

[0096] Reference Figure 8 and Fig. 9 The connecting member 400 may include four parts that are spliced ​​and fixed to each other. The four parts may be respectively located on the sky side of the display device, the ground side of the display device, the left side of the display device, and the right side of the display device. The four parts of the connecting member 400 may be arranged one by one corresponding to the four parts of the back panel 100. Each part may be arranged as a strip-shaped connecting member 400, thereby making the installation process of the connecting member 400 and the connecting portion 120 more convenient.

[0097] Taking the display device side as an example, the strip connector 400 can be detachably connected to the strip connector 120. The extension direction of the strip connector 400 can be arranged parallel to the extension direction of the strip connector 120, and the strip connector 400 can be arranged parallel to the extension direction of the frame 130.

[0098] When the connector 400 needs to be connected to the back panel 100, the strip connectors 400 located in different directions can be connected to the corresponding strip connecting parts 120 first, and then the multiple components of the back panel 100 can be spliced ​​together to form the back panel 100, thereby making the formation process of the back panel 100 more convenient.

[0099] Reference Figure 8 and Fig. 9 In some possible implementations, the connector 400 may be provided with a fixing groove 410 , and the notch of the fixing groove 410 may face the diffuser 200 . A fixing member 411 may be provided in the fixing groove 410 , and the connector 400 may be fixed relative to the connecting portion 120 through the fixing member 411 .

[0100] By setting a fixing groove 410 on the connecting member 400, with the notch of the fixing groove 410 facing the diffuser plate 200, and setting a fixing member 411 in the fixing groove 410, the interference of the fixing member 411 on the diffuser plate 200 can be reduced, and the fixing member 411 can be prevented from affecting the installation and fixation of the diffuser plate 200. The connecting member 400 can also be relatively fixed to the connecting part 120 through the fixing member 411, thereby ensuring the stability and firmness of the connection.

[0101] Furthermore, by providing the fixing groove 410 and the fixing member 411 , the connector 400 can be relatively fixed to the connecting portion 120 via the fixing member 411 , making the fixing between the connector 400 and the connecting portion 120 more convenient and effective, thereby improving the installation efficiency of the connector 400 .

[0102] Exemplarily, the fixing member 411 may be a fixing bolt. The nut of the fixing bolt may be located in the fixing groove 410, the threaded section of the fixing bolt may pass through the connecting member 400, and the threaded section of the fixing bolt may be threadedly connected to the connecting portion 120, thereby ensuring the stability and firmness of the connection between the connecting member 400 and the connecting portion 120.

[0103] By setting the fixing member 411 as a fixing bolt, the connecting member 400 and the connecting part 120 are connected by the fixing bolt, so that the fixation between the connecting member 400 and the connecting part 120 can be made more flexible, so that the position and tightness of the connecting member 400 can be adjusted by threaded connection.

[0104] Exemplarily, the fixing member 411 can be fixed relative to the connecting portion 120 by means of a snap connection, etc. This arrangement can make the connection process between the connecting member 400 and the connecting portion 120 more convenient, and improve the installation efficiency of the connecting member 400.

[0105] It is easy to understand that the number of the fixing grooves 410 can be set to multiple, and the multiple fixing grooves 410 can be sequentially spaced along the extension direction of the connecting member 400. The fixing grooves 410 can be used to accommodate one or more fixing members 411, so that the connecting member 400 can be relatively fixed to the connecting portion 120 through the multiple fixing members 411, so that the connection between the connecting member 400 and the connecting portion 120 is more stable.

[0106] In some possible implementations, in a direction close to the frame 130 , an edge of the abutting surface 440 and an edge of the diffusion plate 200 may be arranged flush.

[0107] This arrangement can ensure parallel alignment between the abutting surface 440 and the diffuser plate 200 in the direction close to the frame 130, increase the contact area between the diffuser plate 200 and the abutting surface 440 of the connector 400, and improve the stability of the connection between the diffuser plate 200 and the connector 400.

[0108] Alternatively, in the direction approaching the frame 130 , the distance between the edge of the abutting surface 440 and the frame 130 may be smaller than the distance between the edge of the diffusion plate 200 and the frame 130 .

[0109] This arrangement can not only increase the contact area between the diffuser plate 200 and the abutment surface 440 of the connector 400, thereby improving the stability of the connection between the diffuser plate 200 and the connector 400, but also effectively reduce the gap between the diffuser plate 200 and the frame 130, thereby improving the firmness and stability of the connection between the diffuser plate 200 and the back plate 100.

[0110] Reference Figure 8 and Fig. 9 In some possible implementations, the connector 400 may be provided with an extension portion 420, which may be located on a side of the connector 400 away from the frame 130. The extension portion 420 may have an extension surface, which may be located in the same plane as the abutment surface 440, and the extension surface may abut at least a portion of the diffuser 200.

[0111] In this way, the connector 400 can be provided with an extension portion 420, which is located on the side of the connector 400 away from the frame 130. The extension portion 420 has an extension surface, and the extension surface and the abutment surface 440 are located in the same plane. The extension surface abuts against at least a portion of the diffuser plate 200, thereby further increasing the area of ​​the second portion of the diffuser plate 200 and enhancing the stability and firmness between the connector 400 and the diffuser plate 200.

[0112] For example, the connection member 400 may be provided with a bending portion 430 . A first end of the bending portion 430 may be connected to an end of the connection member 400 away from the frame 130 , and a second end of the bending portion 430 may extend away from the diffusion plate 200 .

[0113] The display module may include a reflective sheet 431. The reflective sheet 431 is attached to the surface of the bent portion 430 away from the frame 130, and at least part of the reflective sheet 431 may face the light emitting side of the backlight module 300, thereby enhancing the reflection and propagation effect of light, making the light reflection of the display module more uniform and efficient.

[0114] In some embodiments of the present application, the extension direction of the bending portion 430 can be inclined relative to the thickness direction of the diffuser plate 200, the second end of the bending portion 430 can be away from the connecting member 400 relative to the first end of the bending portion 430, and the second end of the bending portion 430 can be located on the outside of the backlight module, thereby making the reflection effect of light inside the display module more uniform and efficient.

[0115] It is easy to understand that the bending portion 430 can be arranged on the side of the extension portion 420 away from the connector 400. The connector 400, the extension portion 420 and the bending portion 430 can be integrally formed to make the structure of the connector 400, the extension portion 420 and the bending portion 430 more stable.

[0116] Reference Figure 8 and Fig. 9 ,as well as Fig.10 and Fig.11 In some possible implementations, the installation process of the diffusion plates 200 of different specifications can be realized by changing the connecting pieces 400 of different thicknesses, so that the application range of the back plate 100 is wider.

[0117] For example, refer to Figure 8 and Fig. 9 When the distance between the backlight module 300 and the diffuser plate 200 is large, a thicker connector 400 can be connected to the connecting portion 120 so that the distance between the abutting surface 440 of the connector 400 and the connecting portion 120 is large, thereby enabling the diffuser plate 200 to be fixed to the back plate through the thicker connector 400.

[0118] Reference Fig.10 and Fig.11 When the distance between the backlight module 300 and the diffuser plate 200 is small, a connector 400 with a smaller thickness can be connected to the connecting portion 120 so that the distance between the abutting surface 440 of the connector 400 and the connecting portion 120 is smaller, thereby enabling the diffuser plate 200 to be fixed to the back plate through the connector 400 with a smaller thickness.

[0119] In summary, in the display device of the embodiment of the present application, the backlight module 300 and the diffuser plate 200 are arranged on the front side of the main body 110, and the light-emitting side of the backlight module 300 faces the first part of the diffuser plate 200, so that the light from the backlight module 300 is evenly scattered through the diffuser plate 200. The connector 400 can be arranged on the surface of the connecting portion 120 away from the main body 110, and the surface of the connector 400 away from the connecting portion 120 has an abutting surface 440, and the abutting surface 440 abuts against the second part of the diffuser plate 200, so that the second part of the diffuser plate 200 can be fixed to the connecting portion 120 through the connector 400.

[0120] In the related art, the diffuser plate 200 directly abuts against the connection portion 120, and the contact area between the diffuser plate 200 and the connection portion 120 is equal to the area of ​​the parallel opposing portions of the diffuser plate 200 and the connection portion 120. In the embodiment of the present application, at least part of the abutting surface can be located on the inner side of the connection portion 120, so that the area of ​​the second portion of the diffuser plate 200 can be increased, so that the area of ​​the second portion of the diffuser plate 200 is larger than the area of ​​the parallel opposing portions of the diffuser plate 200 and the connection portion 120, so that the contact area of ​​the diffuser plate 200 can be increased, the stability of the connection between the diffuser plate 200 and the back plate 100 can be improved, and the possibility of the diffuser plate 200 being offset can be reduced.

[0121] An embodiment of the present application provides a display device, including a back plate 100 , a backlight module 300 , a connector 400 and a diffusion plate 200 .

[0122] The back panel 100 includes a main body 110 , a connecting portion 120 and a frame 130 which are connected to each other. The connecting portion 120 is arranged around the outside of the main body 110 , and the outer surface of the connecting portion 120 is connected to the frame 130 . The frame 130 extends toward the front side of the main body 110 .

[0123] The backlight module 300 and the diffuser plate 200 are disposed on the front side of the main body 110 , the light emitting side of the backlight module 300 faces the first portion of the diffuser plate 200 , and the second portion of the diffuser plate 200 is fixed to the connecting portion 120 via the connector 400 .

[0124] The second portion of the diffuser plate 200 abuts against the abutting surface of the connecting member 400 , and the area of ​​the second portion of the diffuser plate 200 is larger than the area of ​​the portion of the diffuser plate 200 that is parallel to and opposite to the connecting portion 120 .
