For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0058] 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.

[0059] Display devices usually include display panels, backplanes, middle frames, circuit board assemblies and other structures. Display panels usually refer to liquid crystal displays or other types of display screens for displaying images and information. The backplane is the back support structure of the display panel, usually made of plastic or metal, used to support and fix the display panel, and provide support and protection for the circuit board assemblies inside the display. The middle frame is a structure connecting the display panel and the backplane, usually located at the edge of the display, used to fix the display panel and the backplane, and provide structural support.

[0060] In the current display device field, there are generally two ways to fix the middle frame and the back panel. The first is to use VHB tape to fix the middle frame to the back panel, but this method of bonding has the risk of debonding. The second is to fix the middle frame and the back panel with back-locking screws. This fixing method will expose the screws outside the machine, affecting the neatness of the display device, resulting in a bad user experience and reducing the competitiveness of the product.

[0061] Specifically, taking a TV as an example, a TV with a floating screen structure usually has a middle frame that serves as a decoration and fixes the display panel. The middle frame is usually fixed to the back panel with VHB tape, but this bonding method has the risk of debonding and has not received good market feedback. To improve this phenomenon, Figure 1 As shown, the related art involves a method of fixing the middle frame and the back plate with middle frame back locking screws, but this fixing method leaves the screws exposed on the outside of the machine, sacrificing the neatness of the device to ensure the connection stability between the middle frame and the back plate.

[0062] In view of this, the present application provides a display device, in which fasteners are hidden inside the display device, so that the display device has both connection stability and neatness, thereby improving product competitiveness.

[0063] The specific structure of the display device according to the embodiment of the present application is described below with reference to the accompanying drawings. Figure 2 A schematic diagram of the three-dimensional structure of a display device provided in an embodiment of the present application; Figure 3 A schematic diagram of a partial structure of a display device provided in an embodiment of the present application; Figure 4 for Figure 3 A schematic diagram of an enlarged structure at A of a display device;

[0064] like Figures 2 to 4 As shown, the display device 10 of the embodiment of the present application includes: a display panel 100 , a back plate 200 , a middle frame 300 and a locking structure 400 .

[0065] Among them, the display device 10 can be an OLED (Organic Light Emitting Diode) display device, an LED (Light Emitting Diode, LED) display device, a liquid crystal display (Liquid Crystal Display, LCD) device, etc. This embodiment does not further limit the type of the display device 10.

[0066] The display device includes a display panel 100 , and the display panel 100 is used to display image information such as text and images.

[0067] The display panel 100 has an active area (AA) and a black matrix area (BM) surrounding the display area. The active area is used to display images.

[0068] The display device has an upper side, a lower side, a left side, a right side, a front side, and a rear side. The left side of the display device refers to the side close to the left hand side of the user when the user faces the display panel 100. Similarly, the right side of the display device refers to the side close to the right hand side of the user when the user faces the display panel 100. Correspondingly, the side of the display device 10 facing the user is the front side, and the side of the display device 10 away from the user is the rear side. When the display device 10 is in a standing or hanging state, the absolute height of the upper side of the display device is higher than the absolute height of the lower side.

[0069] The display device also includes a back plate 200, which is arranged on the side of the display panel 100 away from the display surface, that is, the back plate 200 is arranged on the rear side of the display panel 100, and the back plate 200 includes a back plate body 210 and a mounting portion 220, and the mounting portion 220 is arranged in the circumferential direction of the back plate body 210 and protrudes toward the display panel 100, and the mounting portion 220 is used to be fixedly connected to the middle frame 300 and can support the display panel 100 through the middle frame 300.

[0070] Specifically, Figure 2 and Figure 3 As shown, the middle frame 300 includes a shielding portion 310 and a connecting portion 320 arranged at an angle to the shielding portion 310, the shielding portion 310 is located on the circumferential outer side of the mounting portion 220, and the connecting portion 320 is sandwiched between the display panel 100 and the mounting portion 220. The locking structure 400 can connect the mounting portion 220 and the connecting portion 320, so that the middle frame 300 and the back plate 200 can be fastened and connected, and the display panel 100 can also shield the locking structure 400.

[0071] With the display device 10 described above, the back plate 200 is configured to include a back plate body 210 and a mounting portion 220 protruding toward the display panel 100. The middle frame 300 includes a connecting portion 320 and a shielding portion 310 arranged at an angle to the connecting portion 320. The connecting portion 320 is sandwiched between the mounting portion 220 and the display panel 100, that is, the mounting portion 220 and the mounting portion 220 of the back plate 200 form an overlapping relationship in the thickness direction of the display device 10. The locking structure 400 includes a first fastener and a second fastener connected to the first fastener. The mounting portion 220 and the connecting portion 320 are fixed between the first fastener and the second fastener, so that the connecting portion 320 and the mounting portion 220 are locked, thereby playing a role in connecting the back plate 200 and the middle frame 300.

[0072] At the same time, since the display panel 100 is arranged on the connecting portion 320, it can block the locking structure 400 installed on the connecting portion 320, so that the user can hardly see the locking structure 400 from the outside of the display device 10, thereby ensuring the tightness of the connection between the back panel 200 and the middle frame 300 while also improving the neatness of the display panel 100, thereby helping to improve the user experience.

[0073] The specific structure of the backplane is described below with reference to the accompanying drawings. Figure 6 A schematic diagram of the partial structure of the back panel of the display device provided in an embodiment of the present application.

[0074] like Figure 4 and Figure 6 As shown, in some embodiments, the mounting portion 220 of the backplane 200 includes a vertical plate 221 and a support plate 222, and the vertical plate 221 is arranged at the circumferential edge of the backplane body 210 and is arranged at an angle to the backplane body 210. It should be noted that the angle between the vertical plate 221 and the backplane body is between 60° and 120°. Exemplarily, the angle between the vertical plate 221 and the backplane body can be 90°.

[0075] In some embodiments, the support plate 222 is connected to the vertical plate 221 and is spaced apart from the back plate body 210 so that the back plate body 210, the vertical plate 221 and the support plate 222 form a receiving space 201, and the receiving space 201 can be used to install electronic components.

[0076] In some embodiments, a first mounting hole 223 is provided on the support plate 222, and a second mounting hole 321 corresponding to the first mounting hole 223 is provided on the connecting portion 320, and the locking structure 400 is passed through the first mounting hole 223 and the second mounting hole 321, thereby realizing a fastened connection between the support plate 222 and the connecting portion 320, and further realizing a fastened connection between the back plate 200 and the middle frame 300.

[0077] It should be noted that the connection portion 320 is directly connected to the display panel 100. For example, the connection portion 320 can be arranged in parallel with the display panel 100 to improve the stability of the connection of the display panel 100. The support plate 222 is connected to the display panel 100 through the connection portion 320. For example, the support plate 222, the connection portion 320 and the display panel 100 can be arranged in parallel to ensure the stability of the connection between the back plate 200, the middle frame 300 and the display panel 100.

[0078] Since the setting of the support plate 222 is related to the stability of the display panel 100 , the angle between the vertical plate 221 and the support plate 222 can be determined according to actual conditions to ensure the stable connection among the back plate 200 , the middle frame 300 and the display panel 100 .

[0079] The specific structure of the middle frame is described below with reference to the accompanying drawings. Figure 7 A schematic diagram of the partial structure of the middle frame of the display device provided in an embodiment of the present application.

[0080] like Figure 4 and Figure 7 As shown, in some embodiments, the middle frame 300 includes a shielding portion 310 and a connecting portion 320. The connecting portion 320 is used to connect to the support plate 222 of the back plate 200 on one hand, and is also used to bond to the display panel 100 on the other hand.

[0081] It should be noted that the shielding portion 310 is disposed at an angle with the connecting portion 320 and shields the display panel 100 and the mounting portion 220 in the circumferential direction.

[0082] It should be noted that the angle between the shielding portion 310 and the connecting portion 320 depends on the setting angle of the display panel 100. For example, when the display panel 100 is a plane, the connecting portion 320 can be arranged parallel to the display panel, and the shielding portion 310 can shield the edge of the display panel and the edge of the vertical plate 221, thereby helping to improve the neatness of the appearance of the display device 10.

[0083] In some embodiments, the middle frame 300 may also include a limiting portion 330 arranged on the inner edge of the connecting portion 320, the limiting portion 330 is arranged at an angle to the connecting portion 320, the shielding portion 310, the connecting portion 320 and the limiting portion 330 form a limiting space for limiting the mounting portion 220 of the back plate 200, and when the back plate 200 moves relative to the middle frame 300, the shielding portion 310 and the limiting portion 330 can limit the mounting portion 220, thereby further ensuring the connection stability between the back plate 200 and the middle frame 300.

[0084] In some embodiments, the shielding portion 310 may be a shielding plate, the connecting portion 320 may be a connecting plate, and the limiting portion 330 may be a limiting plate. The above structure is easy to process and has low production cost.

[0085] like Figure 3 and Figure 4 As shown, in some embodiments, the locking structure 400 has a first end surface facing the display panel 100 , and the first end surface does not protrude from the end surface of the connecting portion 320 facing the display panel 100 .

[0086] In the above structure, since the end surface of the connecting portion 320 facing the display panel 100 is used to connect the display panel 100, it is necessary to ensure the flatness of the end surface connected to the display panel 100. Once the first end surface of the locking structure 400 protrudes from the end surface of the connecting portion 320 facing the display panel 100, it is easy to reduce the contact area between the display panel 100 and the connecting portion 320, resulting in an unstable connection between the display panel 100 and the connecting portion 320. Therefore, making the first end surface not protrude from the end surface of the connecting portion 320 facing the display panel 100 helps to ensure the contact area between the connecting portion 320 and the display panel 100.

[0087] Exemplarily, the first end surface of the locking structure 400 may be flush with or lower than the end surface of the connection portion 320 facing the display panel 100. Preferably, the first end surface of the locking structure 400 is flush with the end surface of the connection portion 320 facing the display panel 100, so that the first end surface of the locking structure 400 can also become a part of the connection plane of the display panel 100, ensuring the stability of the connection of the display panel 100.

[0088] like Figure 4 As shown, in some embodiments of the present application, the display device also includes an adhesive 500, which bonds the display panel 100 to the support plate, and the adhesive covers the first end surface of the locking structure 400, so that the display panel 100 can be stably connected to the support plate. At the same time, the adhesive 500 can cover the locking structure 400 and the adhesive 500 is not exposed on the display panel 100, so that the display panel 100 can cover the locking structure 400, thereby ensuring the neat appearance of the display device.

[0089] For example, the adhesive 500 may be VHB adhesive (Very High Bond tape).

[0090] Continue to refer to Figure 3 and Figure 4 In some embodiments, the locking structure 400 has a second end surface facing the back plate body 210 , and the second end surface does not protrude from the end surface of the support plate 222 facing the back plate body 210 .

[0091] In the above structure, since the back plate body 210, the vertical plate 221 and the support plate 222 enclose the accommodation space 201, the accommodation space 201 is used to install electronic components. If the second end surface of the locking structure 400 protrudes from the end surface of the support plate 222 facing the back plate body 210, the electronic components may be damaged. Therefore, making the second end surface of the locking structure 400 not protrude from the end surface of the support plate 222 facing the back plate body 210 helps to reduce the probability of electronic components being damaged.

[0092] Exemplarily, the second end surface of the locking structure 400 may be flush with or lower than the end surface of the support plate 222 facing the back plate body 210. Preferably, the second end surface of the locking structure 400 is flush with the end surface of the support plate 222 facing the back plate body 210. Such a setting can ensure the flatness of the end surface of the support plate 222 facing the back plate body 210, so that no step surface is formed between the second end surface of the locking structure 400 and the support plate 222, thereby further reducing the probability of electronic components being damaged.

[0093] The specific structure of the locking structure is described below with reference to the accompanying drawings. Figure 5 for Figure 3 Schematic diagram of the exploded structure of the display device.

[0094] like Figures 3 to 5 As shown, in some embodiments, the locking structure 400 includes a first fastener and a second fastener, wherein the first fastener includes a fastening screw 410, and the second fastener includes a fastening sleeve 420, the fastening screw 410 is connected to the fastening sleeve 420, and the mounting portion 220 and the connecting portion 320 are clamped between the fastening screw 410 and the fastening sleeve 420. Compared with setting the locking structure as a screw, this setting method eliminates the step of opening threaded holes on the mounting portion 220 and the connecting portion 320, and there is no need to process threads in the openings on the mounting portion 220 and the connecting portion 320, thereby effectively improving the production efficiency of the display device.

[0095] Exemplarily, the fastening screw 410 includes a nail cap 411 and a threaded column 412 connected to the nail cap 411 , and a clamping space for fastening the mounting portion 220 and the connecting portion 320 can be formed between the nail cap 411 and the fastening sleeve 420 .

[0096] Specifically, the fastening screw 410 is passed through the first mounting hole 223 and the second mounting hole 321, the nail cap 411 is arranged in the second mounting hole 321 and connected to the threaded column 412, and the mounting part 220 and the connecting part 320 are clamped between the nail cap 411 and the fastening sleeve 420, thereby achieving the fastening effect of the mounting part 220 and the connecting part 320 through the locking structure 400, thereby achieving the fastening effect of the back panel 200 and the middle frame 300.

[0097] It should be noted that the locking structure 400 can be provided in plurality, that is, a plurality of locking structures 400 are provided at each edge of the display device 10, thereby further ensuring the connection stability between the middle frame 300 and the back plate 200. Exemplarily, 2-6 locking structures are provided at each edge of each display device 10.

[0098] It should also be noted that the above-mentioned multiple locking structures 400 can all be blocked by the display panel 100 .

[0099] The specific structure of the first mounting hole and the second mounting hole is described below with reference to the accompanying drawings.

[0100] like Figure 4 and Figure 5 As shown, in some embodiments, the first mounting hole 223 includes a first hole segment 2231 and a second hole segment 2232 connected to the first hole segment 2231, the first hole segment 2231 is arranged close to the back plate body 210, the diameter of the first hole segment 2231 is greater than the diameter of the second hole segment 2232, and a first abutting surface 2233 can be formed between the first hole segment 2231 and the second hole segment 2232.

[0101] Specifically, the first hole section 2231 is used to accommodate the nail cap 411 of the fastening screw 410, so that the nail cap 411 is accommodated in the first hole section 2231, which can reduce the degree to which the nail cap 411 protrudes from the support plate 222. In addition, the first hole section 2231 also includes a first abutting surface 2233, and the nail cap 411 can abut against the first abutting surface 2233, thereby cooperating with the fastening sleeve 420 to apply a fastening force to the support plate 222 and the connecting portion 320.

[0102] The second mounting hole 321 includes a third hole segment 3211 and a fourth hole segment 3212 connected to the third hole segment 3211. The third hole segment 3211 is set toward the display panel 100. The diameter of the third hole segment 3211 is greater than the diameter of the fourth hole segment 3212. A second abutting surface 3213 is formed between the third hole segment 3211 and the fourth hole segment 3212.

[0103] Specifically, the third hole section 3211 and the fourth hole section 3212 are used to accommodate the threaded column 412 , and the third hole section 3211 is also used to accommodate the fastening sleeve 420 , which helps to reduce the extent to which the fastening sleeve 420 protrudes from the connecting portion 320 .

[0104] During assembly, the fastening screw 410 can be inserted into the first mounting hole 223, and the nail cap 411 of the fastening screw 410 can be abutted against the first abutting surface 2233, so that the fastening sleeve 420 is installed in the third hole section 3211 and abutted against the second abutting surface 3213. The fastening force between the nail cap 411 and the fastening sleeve 420 acts between the first abutting surface 2233 and the second abutting surface 3213, thereby achieving a fastening effect on the connecting portion 320 and the supporting plate 222.

[0105] Exemplarily, when the locking structure 400 includes a fastening screw 410 and a fastening sleeve 420, the end surface of the nail cap 411 facing the back panel body 210 is flush with the end surface of the support plate 222 facing the back panel body 210, thereby ensuring the flatness of the end surface of the support plate 222 facing the back panel body 210, thereby reducing the probability of damage to electronic components.

[0106] Correspondingly, the end surface of the fastening sleeve 420 facing the display panel 100 and the end surface of the threaded column 412 facing the display panel 100 are flush with the end surface of the connecting portion 320 facing the display panel 100. Such a configuration helps to ensure the flatness of the end surface of the connecting portion 320 facing the display panel 100, thereby helping to ensure the contact area between the connecting portion 320 and the display panel 100.

[0107] Exemplarily, the adhesive 500 on the display panel 100 may simultaneously cover the end surface of the fastening sleeve 420 facing the display panel 100 , the end surface of the threaded column 412 facing the display panel 100 , and the end surface of the connecting portion 320 facing the display panel 100 .

[0108] In order to improve the assembly efficiency of the fastening sleeve 420 and the fastening screw 410, a guide portion can be provided on the fastening screw 410, and the guide portion is connected to the threaded column 412. The fastening sleeve 420 can be first sleeved on the guide portion, and the fastening sleeve shell slides along the guide portion to the threaded column 412, thereby improving the assembly efficiency of the fastening sleeve 420 and the fastening screw 410.

[0109] The specific structure of the fastening screw with the guide portion is described below with reference to the accompanying drawings.

[0110] Figure 8 This is a schematic structural diagram of a fastening screw of a display device provided by an embodiment of the present application from a first perspective, wherein: Figure 8 A schematic diagram showing the structure of the fastening screw in an assembled state; Fig. 9 This is a schematic structural diagram of a second viewing angle of a fastening screw of a display device provided in an embodiment of the present application, wherein: Fig. 9 A schematic diagram showing the structure of the fastening screw in an assembled state; Fig.10 This is a schematic diagram of the structure of the display device during assembly provided by an embodiment of the present application.

[0111] like Figures 8 to 10 As shown, in some embodiments, the fastening screw 410 includes a nail cap 411, a threaded column 412 and a guide portion 413, wherein the first end of the threaded column 412 is connected to the nail cap 11, and a guide portion 413 is provided on the end face of the second end of the threaded column 412, and the guide portion 413 is used to make the fastening sleeve 420 slide along it onto the threaded column 412 when installing the fastening sleeve 420, so as to improve the connection efficiency between the threaded column 412 and the fastening sleeve 420.

[0112] Exemplarily, in some embodiments, the guide portion 413 may be a guide plate, and the width of the guide plate may be smaller than the diameter of the threaded column 412 to reduce the connection area between the guide plate and the threaded column 412, so as to facilitate breaking the guide portion 413 after the threaded column 412 and the fastening sleeve 420 are connected.

[0113] Furthermore, in some embodiments, a fracture groove 414 may be provided between the guide plate and the end surface of the second end of the threaded column 412 , and the fracture groove 414 is used to further reduce the connection area between the guide plate and the threaded column 412 , making it easier to break the guide portion 413 .

[0114] Specifically, when assembling the fastening screw 410 and the fastening sleeve 420, the fastening sleeve 420 can be firstly sleeved on the guide part, and the fastening sleeve shell slides along the guide part to the threaded column 412, and then the fastening sleeve 420 is connected to the threaded column 412, so as to lock the back plate 200 and the middle frame 300. After the fastening sleeve 420 is locked, the guide plate can be bent or twisted to break the guide plate from the fracture groove 414. At this time, only the nail cap 411 and the threaded column 412 are left of the fastening screw 410, and the end surface of the threaded column 412 facing the display panel 100, the end surface of the fastening sleeve 420 facing the display panel 100, and the end surface of the connecting portion facing the display panel 100 can be arranged flush, so as to ensure the connection area of ​​the display panel 100.

[0115] Exemplarily, the guide plate may be an arc-shaped structure, that is, the guide plate is bent in the axial direction of the fastening screw 410 , thereby improving the smoothness of sliding of the fastening sleeve 420 on the guide plate.

[0116] It should be noted that if Figures 8 to 10 The structure of the fastening screw 410 shown only exists in the assembly process of the display device. In the finished product of the display device, the fastening screw 410 does not include the structure of the guide portion 413.

[0117] The specific structure of the fastening sleeve and the assembly method of the fastening sleeve and the fastening screw are described below with reference to the accompanying drawings.

[0118] Fig.11 A schematic diagram of the structure of a fastening sleeve of a display device provided in one embodiment of the present application; Fig.11 As shown, in some embodiments, the outer edge of the fastening sleeve 420 includes an arcuate edge 421 and a cutting edge 422 connected to the arcuate edge 421 (the arcuate edge 421 and the cutting edge 422 form a "D-shaped" structure).

[0119] Furthermore, the cutting edge 422 is arranged close to the shielding portion 310, that is, the distance H1 between the cutting edge 422 and the inner hole of the fastening sleeve 420 is smaller than the distance H2 between the arc edge 421 and the inner hole of the fastening sleeve 420. Providing the cutting edge 422 on the fastening sleeve 420 helps to reduce the space occupied by the fastening sleeve 420, thereby making the fastening sleeve 420 more easily shielded by the display panel 100.

[0120] Specifically, the second mounting hole 321 needs to be arranged corresponding to the outer edge of the fastening sleeve 420, so that the second mounting hole 321 can also be shielded by the display panel 100. The projection of the display panel 100 on the support plate 222 shields the fastening sleeve 420 and the second mounting hole 321, thereby preventing the fastening sleeve 420 from being exposed from the edge of the display panel 100, and ensuring the neatness of the appearance of the display device.

[0121] Since the outer edge of the fastening sleeve 420 is a non-circular structure and the second mounting hole 321 is also arranged corresponding to the fastening sleeve 420, the fastening sleeve 420 is difficult to rotate in the second mounting hole 321. In view of this, the fastening sleeve 420 and the fastening screw 410 can be connected by threaded clamping, that is, the fastening sleeve 420 is pressed toward the nail cap 411, so that the internal thread on the fastening sleeve 420 is clamped with the external thread on the fastening screw 410.

[0122] The present application also provides another embodiment of the fastening sleeve 420. Fig.12 A schematic structural diagram of a fastening sleeve of a display device provided in another embodiment of the present application.

[0123] Specifically, Fig.12 As shown, the outer edge of the fastening sleeve 420 is a circular structure, and a mounting groove 423 is provided on the surface of the fastening sleeve 420 facing the display panel 100 . The mounting groove 423 extends along the radial direction of the fastening sleeve 420 . The fastening sleeve 420 is threadedly connected with the fastening screw 410 .

[0124] During assembly, the operator may insert the assembly tool into the assembly groove 423 , and rotate the assembly tool to rotate the fastening sleeve 420 , thereby tightening the fastening sleeve 420 onto the fastening screw 410 .

[0125] On the other hand, an embodiment of the present application further provides a display device 10 , which includes: a display panel 100 , a back plate 200 , a middle frame 300 and a locking structure 400 .

[0126] The back panel 200 is arranged on the rear side of the display panel 100, and the back panel 200 includes a back panel body 210 and a mounting portion 220; the middle frame 300 includes a shielding portion 310 and a connecting portion 320 arranged at an angle to the shielding portion 310, the shielding portion 310 is located on the circumferential outside of the mounting portion 220, the connecting portion 320 is arranged between the display panel 100 and the mounting portion 220 and is used to connect the display panel 100 and the mounting portion 220; the locking structure includes a first fastener and a second fastener connected to each other, the first fastener and the second fastener are used to connect the mounting portion and the connecting portion, and the locking structure 400 is not exposed to the display panel 100 and the middle frame 300.

[0127] The display device 10 is configured such that the back plate 200 includes a back plate body 210 and a protruding mounting portion 220, and the middle frame 300 includes a connecting portion 320 and a shielding portion 310. The connecting portion 320 is located between the mounting portion 220 and the display panel 100, forming an overlapping structure, and the two are tightly connected by the locking structure 400. This design not only ensures a firm connection between the back plate 200 and the middle frame 300, but also shields the locking structure 400 through the display panel 100, so that the locking structure 400 cannot be seen from the outside, thereby improving the neatness of the device.
