[0008] The extension portion is inserted into the mounting hole and the fixing hole;

[0009] The fixed head abuts against the surface of the backlight module facing away from the back plate, and the multiple movable parts abut against the surface of the back plate facing away from the backlight module; or, the fixed head abuts against the surface of the back plate facing away from the backlight module, and the multiple movable parts abut against the surface of the backlight module facing away from the back plate.

[0010] The display device of the embodiment of the present application includes a back plate, a backlight module and a fixing member, wherein the back plate and the backlight module are relatively fixed by the fixing member. The fixing member includes a fixing head, an extension portion and a plurality of movable portions. The fixing head can be connected to a first end of the extension portion, the plurality of movable portions can be connected to a second end of the extension portion, the plurality of movable portions are arranged around the circumference of the extension portion, and the plurality of movable portions are close to or away from each other.

[0011] When the back plate and the backlight module are relatively fixed by the fixing member, the multiple movable parts can be brought close to each other, and then the multiple movable parts close to each other are passed through the fixing hole and the mounting hole. Then the multiple movable parts are moved away from each other, so that the fixing head can abut against one of the backlight module and the back plate, and the multiple movable parts away from each other can abut against the other of the backlight module and the back plate, so that the back plate and the backlight module are relatively fixed by the fixing member, making the connection method of the backlight module and the back plate simpler, thereby improving the assembly efficiency of the display device.

[0012] In some embodiments of the present application, the fixing member includes a plurality of elastic parts, and the plurality of elastic parts are arranged corresponding to the plurality of movable parts;

[0013] The first end of the elastic part is connected to the second end of the extending part, the second end of the elastic part is close to or far away from the central axis of the extending part, and the second end of the elastic part is connected to the movable part.

[0014] With such arrangement, when the back plate and the backlight module are relatively fixed by the fixing member, the second end of the elastic part can be brought close to the central axis of the extension part, so that the elastic part drives the multiple movable parts to approach each other, so that the multiple movable parts approaching each other can pass through the fixing hole and the mounting hole;

[0015] When the multiple movable parts close to each other pass through the fixing hole and the mounting hole, the second end of the elastic part is reset and moves away from the central axis of the extension part, thereby driving the multiple movable parts away from each other through the elastic part, so that the multiple movable parts away from each other can abut against the back panel or backlight module.

[0016] In some embodiments of the present application, the movable portion is disposed on a side of the elastic portion away from the central axis of the extending portion;

[0017] The movable portion has a guide surface, and in a direction close to the fixed head, the guide surface is inclined toward a direction away from the central axis of the extending portion.

[0019] When the back panel and the backlight module are relatively fixed by the fixing parts, the movable part is gradually moved closer to the back panel and the backlight module, so that the guide surface of the movable part can abut against the inner wall of the mounting hole or the inner wall of the fixing hole, and the movable part can move toward the central axis of the extension part through the guiding surface, so that the multiple movable parts are close to each other, thereby making the connection process of the backlight module and the back panel through the fixing parts more convenient.

[0020] In some embodiments of the present application, the movable portion has a fitting surface, and the fitting surface is used to abut against the backlight module or the back plate;

[0021] The fitting surface is connected to the guide surface, and the fitting surface is perpendicular to the central axis.

[0022] With such arrangement, when the multiple movable parts that are close to each other pass through the fixing hole and the mounting hole, the second end of the elastic part is reset and moves away from the central axis of the extension part, thereby driving the multiple movable parts to move away from each other through the elastic part. The multiple movable parts that are away from each other can abut against the back panel or the backlight module through the fitting surface, so that the fitting between the movable parts and the back panel or the backlight module is more stable.

[0023] In some embodiments of the present application, the fixing head has a pressing surface and a curved surface;

[0024] The pressing surface is used to abut against the backlight module or the back plate, and the arc surface is convexly arranged relative to the pressing surface.

[0025] With such arrangement, when the back plate and the backlight module are relatively fixed by the fixing member, the arc surface can be pressed, thereby pushing the fixing head close to the back plate or the backlight module through the arc surface. When the multiple movable parts close to each other pass through the fixing holes and the mounting holes, the pressing surface of the fixing head can abut against the back plate or the backlight module, thereby making the abutment between the fixing head and the back plate or the backlight module more stable.

[0028] In some embodiments of the present application, at least one of the fixed head, the extending portion and the movable portion is made of insulating material.

[0029] With such an arrangement, at least one of the fixed head, the extension part and the movable part is made of insulating material, thereby reducing the possibility of conduction between the fixing part and other structures, and reducing the possibility of the back panel and the backlight module being electrically connected to other structures through the fixing part.

[0032] In this arrangement, in the thickness direction of the back plate, the orthographic projection of the fixing hole on the plane where the back plate is located is located inside the orthographic projection of the mounting hole on the plane where the back plate is located;

[0033] When the back panel and the backlight module are relatively fixed by the fixing parts, the fixing head is pressed to allow multiple movable parts to enter the mounting hole. The size of the mounting hole is larger than the size of the fixing hole, so that the mounting hole can play a certain guiding role, making the process of multiple movable parts passing through the mounting hole and the fixing hole more convenient.

[0062] As described in the background technology, refer to Figure 1 In the related art, the display device includes a back plate 100 and a backlight module 200. The backlight side of the backlight module 200 faces the back plate 100. The backlight module 200 can be fixed relative to the back plate 100 by means of screws 10. For example, when the backlight module needs to be fixed relative to the back plate by means of screws, a mounting hole can be formed on the back plate, a through hole can be formed in the backlight module, and then an internal thread can be formed on the inner wall of the mounting hole by means of tapping.

[0063] The threaded section of the screw can then be passed through the through hole of the backlight module so that the threaded section of the screw can be matched with the internal thread of the mounting hole of the back plate, so that the backlight module and the back plate can be fixed by the screw. However, in the above connection method, it is necessary to drill and tap the back plate, and it is necessary to use a tool such as a screwdriver to connect the threaded section of the screw with the back plate thread, which makes the connection method of the backlight module and the back plate complicated and the assembly efficiency of the display device is low.

[0064] In view of this, the display device of the embodiment of the present application includes a back plate, a backlight module and a fixing member, wherein the back plate and the backlight module are relatively fixed by the fixing member. The fixing member includes a fixing head, an extension portion and a plurality of movable portions. The fixing head can be connected to the first end of the extension portion, the plurality of movable portions can be connected to the second end of the extension portion, the plurality of movable portions are arranged around the circumference of the extension portion, and the plurality of movable portions are close to or away from each other.

[0065] When the back plate and the backlight module are relatively fixed by the fixing member, the multiple movable parts can be brought close to each other, and then the multiple movable parts close to each other are passed through the fixing hole and the mounting hole. Then the multiple movable parts are moved away from each other, so that the fixing head can abut against one of the backlight module and the back plate, and the multiple movable parts away from each other can abut against the other of the backlight module and the back plate, so that the back plate and the backlight module are relatively fixed by the fixing member, making the connection method of the backlight module and the back plate simpler, thereby improving the assembly efficiency of the display device.

[0072] 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.

[0073] Reference Figure 2-Figure 4 The embodiment of the present application provides a display device, including a back plate 100, a backlight module 200 and a fixing member 300. The backlight side of the backlight module 200 faces the back plate 100, and the back plate 100 and the backlight module 200 are relatively fixed by the fixing member 300.

[0074] In some possible implementations, the back plate 100 can at least be used to support and protect the backlight module 200, reducing the possibility of deformation and damage of the backlight module 200. The back plate 100 can 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.

[0075] Exemplarily, the back plate 100 may be provided with a fixing hole 110. The fixing hole 110 may be used to connect the fixing member 300. The number of the fixing holes 110 may be set to multiple, and the multiple fixing holes 110 may be set at the edge of the back plate 100. The multiple fixing holes 110 may also be set at the corners of the back plate 100 to reduce the interference of the fixing member 300 located in the fixing hole 110 with other structures of the display device.

[0076] The backlight module 200 may be configured as a light panel or the like. The backlight module 200 may be provided with a mounting hole 210. The mounting hole 210 may be used to connect the fixing member 300. The mounting hole 210 is communicated with the fixing hole 110, and the fixing member 300 may be inserted into the mounting hole 210 and the fixing hole 110, so that the back plate 100 and the backlight module 200 may be fixed to each other through the fixing member 300.

[0077] Exemplarily, the backlight module 200 may include a substrate 201 and a plurality of light emitting elements 202. The substrate 201 may be used to support and connect the plurality of light emitting elements 202. The backlight side of the light emitting element 202 may face the substrate 201, and the light emitting side of the light emitting element 202 may face away from the substrate 201, so that the plurality of light emitting elements 202 may emit light away from the substrate 201.

[0078] The light emitting element 202 may be a light emitting diode (LED). A plurality of light emitting elements 202 may form a plurality of pixel units, so that light beams of different colors may be emitted through the plurality of pixel units.

[0079] The backlight module 200 may further include a reflective sheet 203 . The reflective sheet 203 may be disposed on a surface of the substrate 201 , and a reflective surface of the reflective sheet 203 may be away from the substrate 201 , so that the reflective sheet 203 reflects light from the light emitting element 202 .

[0080] The reflective sheet 203 may be provided with an opening, and the opening may be used to accommodate the light emitting element 202 , so that the light emitting element 202 can be connected to the substrate 201 through the opening of the reflective sheet 203 .

[0081] The reflective surface of the reflector 203 faces the backlight side of the light emitting element 202. When the light emitting elements 202 are in a light emitting state, the light emitting elements 202 can emit light from the light emitting side away from the substrate 201, and can also emit light from the backlight side toward the substrate 201.

[0082] When the light emitting element 202 emits light toward the substrate 201 through the backlight side, the reflective surface of the reflective sheet 203 faces the backlight side of the light emitting element 202. The reflective sheet 203 can reflect the light from the backlight side of the light emitting element 202, so that the light from the backlight side of the light emitting element 202 propagates away from the direction of the substrate 201. Therefore, by setting the reflective sheet 203 to reflect the light, the light output brightness of the backlight module 200 can be further increased.

[0083] The backlight module 200 may be provided with a mounting hole 210. The mounting hole 210 may penetrate the substrate 201 and the reflector 203, the first end of the mounting hole 210 may be located on the surface of the substrate 201 away from the reflector 203, and the second end of the mounting hole 210 may be located on the surface of the reflector 203 away from the substrate 201. The mounting hole 210 may be staggered with the light emitting element 202 to reduce interference of the light emitting element 202 on the position of the mounting hole.

[0084] In some possible implementations, the fixing member 300 may include an extension portion 320 , and the extension portion 320 may pass through the back plate 100 and the backlight module 200 . The fixing member 300 may further include a fixing head 310 . The fixing head 310 may be connected to a first end of the extension portion 320 .

[0085] The fixing member 300 may further include a plurality of movable portions 330. The plurality of movable portions 330 may be connected to the second end of the extension portion 320, and the plurality of movable portions 330 may be arranged around the circumference of the extension portion 320, and the plurality of movable portions 330 may be moved closer to or farther from each other, so that the back plate 100 and the backlight module 200 are clamped and fixed by the plurality of movable portions 330 and the fixing head 310.

[0086] The back plate 100 and the backlight module 200 may be fixed to each other via a fixing member 300 , and the extension portion 320 may be inserted into the mounting hole 210 and the fixing hole 110 .

[0087] The fixed head 310 can abut the surface of the backlight module 200 away from the back panel 100, and the multiple movable parts 330 can abut the surface of the back panel 100 away from the backlight module 200, or the fixed head 310 abuts the surface of the back panel 100 away from the backlight module 200, and the multiple movable parts 330 abut the surface of the backlight module 200 away from the back panel 100, so that the back panel 100 and the backlight module 200 can be clamped and fixed by the fixed head 310 and the multiple movable parts 330.

[0088] The fixed head 310, the extension part 320 and the movable part 330 can be integrally arranged. This arrangement makes the overall design of the display device simple, reduces the number of parts, reduces the manufacturing cost and assembly complexity. In addition, the integral arrangement of the fixed head 310, the extension part 320 and the movable part 330 can improve the stability of the overall structure of the fixing member 300, reduce problems such as looseness and friction, and extend the service life.

[0089] Exemplarily, at least one of the fixing head 310, the extension portion 320 and the movable portion 330 is made of insulating material, thereby reducing the possibility of conduction between the fixing member 300 and other structures, and reducing the possibility of the back panel 100 and the backlight module 200 being electrically connected to other structures through the fixing member 300.

[0090] It is easy to understand that the fixed head 310 , the extension part 320 and the movable part 330 are integrally arranged, and the fixed head 310 , the extension part 320 and the movable part 330 are made of insulating materials.

[0091] When the side of the back plate 100 away from the backlight module 200 needs insulation protection, the fixed head 310 or the multiple movable parts 330 located on the side of the back plate 100 away from the display device can be made of insulating materials. When the side of the backlight module 200 away from the back plate 100 needs insulation protection, the fixed head 310 or the multiple movable parts 330 located on the side of the backlight module 200 away from the back plate 100 can be made of insulating materials.

[0092] When the fixing head 310 abuts against the surface of the backlight module 200 facing away from the back plate 100 , the fixing head 310 may abut against the surface of the reflective sheet 203 facing away from the substrate 201 .

[0093] Alternatively, when the plurality of movable portions 330 abut against the surface of the backlight module 200 away from the back plate 100 , the plurality of movable portions 330 may abut against the surface of the reflective sheet 203 away from the substrate 201 .

[0094] With this arrangement, the reflective sheet 203 can abut against the fixing head 310 or the movable portion 330 , thereby increasing the contact area between the backlight module 200 and the fixing member 300 , thereby improving the stability of the connection between the backlight module 200 and the fixing member 300 .

[0095] Reference Figure 5-Figure 7 In some possible implementations, when the fixing member 300 is in the first state, the plurality of movable portions 330 may be close to each other so that the plurality of movable portions 330 may enter the mounting hole 210 and the fixing hole 110 .

[0096] When the fixing member 300 is in the second state, the plurality of movable portions 330 are away from each other, so that the plurality of movable portions 330 can abut against the back plate 100 or the backlight module 200 .

[0097] When the back plate 100 and the backlight module 200 are relatively fixed by the fixing member 300, the fixing member 300 can be placed in a first state, the multiple movable parts 330 are close to each other, and then the multiple movable parts 330 close to each other are passed through the fixing hole 110 and the mounting hole 210. Then the fixing member 300 is placed in a second state, the multiple movable parts 330 are separated from each other, so that the fixing head 310 can abut against one of the backlight module 200 and the back plate 100, and the multiple movable parts 330 separated from each other can abut against the other of the backlight module 200 and the back plate 100, so that the back plate 100 and the backlight module 200 are relatively fixed by the fixing member 300.

[0098] Reference Figure 5-Figure 7 In some possible implementations, the fixing member 300 may include a plurality of elastic parts 340. The plurality of elastic parts 340 and the plurality of movable parts 330 may be arranged correspondingly, so that the plurality of elastic parts 340 can improve the flexibility of the movable parts 330 to move closer to or farther from each other.

[0099] The first end of the elastic portion 340 may be connected to the second end of the extending portion 320 , the second end of the elastic portion 340 may be close to or away from the central axis of the extending portion 320 , and the second end of the elastic portion 340 may be connected to the movable portion 330 .

[0100] For example, when the fixing member 300 is in the first state, the second ends of the plurality of elastic portions 340 may be close to the central axis of the extension portion 320, and the plurality of movable portions 330 may be close to each other. When the fixing member 300 is in the second state, the second ends of the plurality of elastic portions 340 may be away from the central axis of the extension portion 320, and the plurality of movable portions 330 may be away from each other.

[0101] When the back panel 100 and the backlight module 200 are relatively fixed by the fixing member 300, the fixing member 300 can be placed in a first state, and the second end of the elastic portion 340 is close to the central axis of the extension portion 320, so that the multiple movable portions 330 are driven to approach each other through the elastic portion 340, so that the multiple movable portions 330 approaching each other can pass through the fixing hole 110 and the mounting hole 210.

[0102] When the multiple movable parts 330 that are close to each other pass through the fixing hole 110 and the mounting hole 210, the fixing member 300 can be in the second state, and the second end of the elastic part 340 is reset and away from the central axis of the extension part 320, so that the multiple movable parts 330 are driven away from each other by the elastic part 340, so that the multiple movable parts 330 that are away from each other can abut against the back panel 100 or the backlight module 200.

[0103] It is easy to understand that the extension direction of the elastic part 340 can be arranged parallel to the extension direction of the extension part 320. When the back plate 100 and the backlight module 200 are relatively fixed by the fixing member 300, the elastic part 340 can be located in the fixing hole 110 and / or the mounting hole 210.

[0104] For example, when the fixing head 310 abuts against the backlight module 200, the elastic portion 340 can be located in the fixing hole 110, and the second end of the elastic portion 340 can be located outside the fixing hole 110. When the fixing head 310 abuts against the back plate 100, the elastic portion 340 can be located in the mounting hole 210, and the second end of the elastic portion 340 can be located outside the mounting hole 210.

[0105] For example, the number of the elastic parts 340 can be two. The two elastic parts 340 can be arranged at intervals, and the two elastic parts 340 are respectively located on both sides of the central axis of the extension part 320. A buffer groove can be formed between the two elastic parts 340.

[0106] When the fixing member 300 is in the first state, the two elastic parts 340 are close to each other, and the side walls of the buffer groove are close to each other, so that the two movable parts 330 connected to the two elastic parts 340 are close to each other.

[0107] In some possible implementations, the movable portion 330 may be disposed on a side of the elastic portion 340 away from the central axis of the extending portion 320 .

[0108] Exemplarily, the movable portion 330 may have a guide surface 331. In a direction close to the fixing head 310, the guide surface 331 is inclined toward a direction away from the central axis of the extension portion 320.

[0109] Reference Figure 5-Figure 7 When the back plate 100 and the backlight module 200 are relatively fixed by the fixing member 300 , the movable part 330 can be gradually moved closer to the back plate 100 and the backlight module 200 , so that the guide surface 331 of the movable part 330 can abut against the inner wall of the mounting hole 210 or the inner wall of the fixing hole 110 .

[0110] The movable portion 330 can move toward the central axis of the extension portion through the guide surface 331 , so that the plurality of movable portions 330 are close to each other, thereby making the connection process between the backlight module 200 and the back plate 100 through the fixing member 300 more convenient.

[0111] The movable part 330 may have a bonding surface 332, and the bonding surface 332 may be used to abut the backlight module 200 or the back plate 100. The bonding surface 332 may be connected to the guide surface 331, and the bonding surface 332 may be perpendicular to the central axis. Multiple movable parts 330 that are far away from each other can abut against the back plate 100 or the backlight module 200 through the bonding surface 332, so that the bonding between the movable part 330 and the back plate 100 or the backlight module 200 is more stable.

[0112] Exemplarily, the fixing head 310 has a pressing surface and a curved surface. The pressing surface can be used to abut against the backlight module 200 or the back plate 100, and the curved surface can be convex relative to the pressing surface.

[0113] When the back plate 100 and the backlight module 200 are relatively fixed by the fixing member 300 , the arc surface can be pressed, so that the fixing head 310 is pushed close to the back plate 100 or the backlight module 200 by the arc surface.

[0114] When the plurality of movable parts 330 close to each other pass through the fixing hole 110 and the mounting hole 210 , the pressing surface of the fixing head 310 can abut against the back plate 100 or the backlight module 200 , thereby making the abutment between the fixing head 310 and the back plate 100 or the backlight module 200 more stable.

[0115] Reference Figure 5-Figure 8 In some possible implementations, the fixing head 310 may abut against the surface of the backlight module 200 that is away from the back plate 100, and the plurality of movable parts 330 may abut against the surface of the back plate 100 that is away from the backlight module 200. In the thickness direction of the back plate 100, the orthographic projection of the fixing hole 110 on the plane where the back plate 100 is located is located inside the orthographic projection of the mounting hole 210 on the plane of the back plate 100.

[0116] In the thickness direction of the back plate 100, the orthographic projection of the fixing hole 110 on the plane where the back plate 100 is located is located inside the orthographic projection of the mounting hole 210 on the plane where the back plate 100 is located. When the back plate 100 and the backlight module 200 are relatively fixed by the fixing member 300, the fixing head 310 is pressed to allow the multiple movable parts 330 to enter the mounting hole 210. The size of the mounting hole 210 is larger than that of the fixing hole 110, so that the mounting hole 210 can play a certain guiding role, making the process of the multiple movable parts 330 passing through the mounting hole 210 and the fixing hole 110 more convenient.

[0117] Exemplarily, the backlight module 200 may be provided with a first receiving groove 220. The first receiving groove 220 accommodates at least a portion of the fixing head 310, thereby reducing the influence of the fixing head 310 on the component installation and use process of one side of the backlight module 200.

[0118] And / or, the back plate 100 may be provided with a second receiving groove 120. The second receiving groove 120 accommodates at least a portion of the movable portion 330, thereby reducing the influence of the movable portion 330 on the component installation process and use process of one side of the back plate 100.

[0119] Reference Fig. 9 and Fig.10 , part of the back plate 100 may be located inside the mounting hole 210. Alternatively, part of the backlight module 200 may be located inside the fixing hole 110, so that the connection between the back plate 100 and the backlight module 200 is more stable.

[0120] In summary, the display device of the embodiment of the present application includes a back plate 100, a backlight module 200 and a fixing member 300, and the back plate 100 and the backlight module 200 are relatively fixed by the fixing member 300.

[0121] When the back plate 100 and the backlight module 200 are fixed relative to each other by the fixing member 300, the plurality of movable parts 330 can be brought close to each other, and then the plurality of movable parts 330 close to each other are passed through the fixing hole 110 and the mounting hole 210. The plurality of movable parts 330 are then moved away from each other, so that the fixing head 310 can abut against one of the backlight module 200 and the back plate 100.

[0122] Multiple movable parts 330 that are far away from each other can abut against the backlight module 200 and the back panel 100, so that the back panel 100 and the backlight module 200 are relatively fixed through the fixing member 300, making the connection method of the backlight module 200 and the back panel 100 simpler, thereby improving the assembly efficiency of the display device.
