Description

Technical Field

[0001] This application relates to the field of display device technology, and more particularly to a display device. Background Technology

[0002] This application relates to outdoor display equipment, including but not limited to outdoor display screens, highway information display screens, electronic bus stop signs at airports and train stations, construction site safety monitoring screens, and outdoor sports venue information display systems.

[0003] In related technologies, display devices include a protective frame, a protective back cover, and a display unit for display. The protective frame and the protective back cover together form a cavity for accommodating the display unit. However, because there are assembly gaps between the protective frame and the display unit, and between the protective back cover and the display unit, the display device suffers from unreliable fixing of the display unit, resulting in poor stability and sealing of the display device. Utility Model Content

[0004] This application provides a display device aimed at solving the technical problem of unreliable fixing of the display unit in the display device, so as to improve the fixing reliability of the display unit and thereby improve the stability of the internal structure of the display device.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a display device, including:

[0007] The display unit includes:

[0008] Display module;

[0009] A module border surrounds the outer periphery of the display module;

[0010] An elastic element is connected to the module frame and extends circumferentially along the module frame, with the outer peripheral surface of the elastic element protruding from the outer peripheral wall of the module frame.

[0011] Housing assembly, including:

[0012] A protective frame is provided around the outer periphery of the display unit. An assembly gap is formed between the inner wall of the protective frame and the outer peripheral wall of the corresponding module frame. The elastic element is located within the assembly gap and abuts against the inner wall of the protective frame to restrict the movement of the display unit in a first direction and a second direction. The first direction and the second direction are both perpendicular to the thickness direction of the display unit.

[0013] Multiple fixed brackets are provided along the thickness direction of the display unit. Each fixed bracket is located on the side of the display unit away from its display side, and the multiple fixed brackets are arranged circumferentially at intervals along the edge of the display unit. One end of each fixed bracket is connected to the protective frame, and the other end is connected to the display unit.

[0014] The protective frame has a first limiting structure on the side facing the fixed bracket, and each fixed bracket has a second limiting structure adapted to the first limiting structure. The first limiting structure has a first limiting surface, and the second limiting structure has a second limiting surface. The first limiting surface and the second limiting surface abut against each other in the thickness direction of the display unit to restrict the movement of the display unit in its own thickness direction.

[0015] In this embodiment, a circumferentially extending elastic element is provided on the outer wall of the module frame of the display module. This allows the display unit to abut against the inner circumferential wall of the protective frame via the elastic element, filling the assembly gap between the display unit and the protective frame. This compensates for assembly gaps caused by processing or installation errors of the protective frame and the display unit, ensuring that the display unit is fixed relative to the protective frame in both the first and second directions. Furthermore, the elastic element creates a circumferential flexible constraint between the display unit and the protective frame. When the display unit tends to shift in either the first or second direction, the elastic element's rebound force causes the display unit to shift back until the forces on the display unit are balanced in both directions, restoring the display area to its centered position, thereby improving the visual effect of the display device. Each fixing bracket has one end engaged with the protective frame via a first and second limiting structure, and the other end of each fixing bracket facing the display unit is connected to the display unit, ensuring that the display unit is fixed relative to the protective frame in all three directions. This ensures that the display unit is fixed relative to the protective frame in the vertical, horizontal, and front-back directions, thereby improving the fixation reliability and stability of the display device. This prevents the display device from shifting within the protective frame, thus avoiding collisions between the display unit and the protective frame. While protecting the display unit, it also improves the sealing performance between the display unit and the protective frame.

[0016] In some embodiments, the outer peripheral wall of the module frame has a circumferentially extending limiting groove, the opening of the limiting groove facing the protective frame, the elastic member being disposed in the limiting groove, and the end of the elastic member facing the protective frame protruding from the opening of the groove.

[0017] This design limits and fixes the elastic component, improving its stability relative to the module frame during the assembly process and preventing displacement or detachment.

[0018] In some embodiments, both sides of the slot have limiting flanges extending toward the center of the slot, and an avoidance gap is formed between the limiting flanges on both sides.

[0019] The elastic element includes a connecting part and an abutting part that are connected to each other. The connecting part is disposed in the limiting groove, and the abutting part passes through the clearance notch and protrudes from the outer peripheral wall of the module frame.

[0020] This design further enhances the stability of the elastic element relative to the module frame, preventing the elastic element from shifting or coming off.

[0021] In some embodiments, the cross-sectional width of the connecting portion is greater than the cross-sectional width of the abutting portion; and / or,

[0022] The elastic element is at least one of a spring, a sheet, a silicone component, and a rubber component.

[0023] This design serves two purposes: firstly, it allows the shape of the elastic element to adapt to the enclosure shape formed by the mounting groove and the limiting fold; secondly, the limitation of the elastic element enables it to function as a flexible buffer, error compensation, and stable constraint.

[0024] In some embodiments, the first limiting structure is a limiting groove, and the second limiting structure is a limiting protrusion;

[0025] The limiting protrusion has an inclined angle between one side surface of the display unit in the thickness direction and the thickness direction of the display unit, and the surface with the inclined angle is formed as the first limiting surface.

[0026] The limiting groove has an inclined angle on the groove wall surface on the same side as the first limiting surface in the thickness direction of the display unit, and the groove wall surface with the inclined angle is formed as the second limiting surface.

[0027] In this way, the setting of the limiting protrusion and the limiting groove is simple in structure and facilitates the snap-fit ​​of the protective frame and each fixed bracket; the setting of the first limiting surface and the second limiting surface with the inclined angle with the thickness direction of the display unit makes the fit between the limiting protrusion of each fixed bracket and the limiting groove of the protective frame smoother and more seamless, and the installation of each fixed bracket is more convenient and labor-saving.

[0028] In some embodiments, the housing assembly further includes a protective rear cover disposed on the side of the display unit opposite to its display side and connected to the protective frame;

[0029] Each of the protective back cover and each of the fixed brackets has an elastic arm at the corresponding position. Along the thickness direction perpendicular to the display unit, each of the fixed brackets is located between the elastic arm and the protective frame. The elastic arm abuts against the fixed bracket so that the limiting protrusion always has a tendency to move into the limiting groove to prevent the limiting protrusion from falling out of the limiting groove.

[0030] This configuration improves the connection accuracy between each fixed bracket and the protective frame, enhances the positional accuracy of the fixed brackets, and thus improves the reliability of the display unit being fixed relative to the protective frame in its thickness direction.

[0031] In some embodiments, each of the elastic arms includes a support arm and an abutment arm connected in sequence. The end of the support arm away from the abutment arm is fixedly connected to the protective rear shell, and the end of the abutment arm away from the support arm abuts against the corresponding fixed bracket. There is an angle between the support arm and the abutment arm.

[0032] This design provides deformation allowance for the fit between the fixed brackets and the protective frame, thereby reducing the manufacturing difficulty of the protective frame and the fixed brackets while ensuring the assembly accuracy between the protective shell, the fixed brackets and the protective frame.

[0033] In some embodiments, the protective back cover has a connecting seat, which is connected to the display unit, and the connecting seat and the elastic arm are an integral structure.

[0034] This design simplifies manufacturing and reduces assembly errors.

[0035] In some embodiments, the protective frame has a mounting groove extending circumferentially on the side facing the protective back cover, and the display device further includes a seal disposed in the mounting groove to seal the gap between the protective frame and the protective back cover.

[0036] This design improves the sealing performance and reliability between the protective back cover and the protective frame.

[0037] In some embodiments, the protective frame has a positioning groove extending circumferentially on the side facing the protective rear shell, and the protective rear shell has a positioning protrusion extending circumferentially thereon, the positioning groove matching the positioning protrusion.

[0038] The mounting slot is located on the side of the positioning slot near the fixed bracket.

[0039] This design ensures that dust and moisture from the external environment are first blocked by the positioning groove and positioning protrusion, and then sealed by the sealing element in the mounting groove, providing double protection and reducing the aging rate of the sealing element, thereby improving the sealing performance and reliability of the display device.

[0080] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0081] This application relates to outdoor display equipment, including but not limited to outdoor display screens, highway information display screens, electronic bus stop signs at airports and train stations, construction site safety monitoring screens, and outdoor sports venue information display systems.

[0082] In some embodiments, combined with Figure 1 , Figure 2 and Figure 3 As shown, the display device 100 includes a housing assembly 120, which includes a protective frame 121 and a protective rear shell 123. The protective frame 121 and the protective rear shell 123 are detachably connected to form an accommodating cavity. Figure 4 and Figure 5 As shown, the display device 100 also includes a display unit 110. A protective frame 121 surrounds the outer periphery of the display unit 110 and directly contacts the module frame 112 within the display unit 110. A protective back cover 123 is disposed on the side of the display unit 110 opposite to its display side. In outdoor environments, the display device 100 must possess dustproof and waterproof performance. Therefore, the display device 100 has strict requirements on its external dimensions to improve its sealing performance and avoid the generation of assembly gaps 1215. Furthermore, screws and nuts cannot be used to directly connect the protective frame 121 to the display unit 110, nor can the protective back cover 123 to the display unit 110, to avoid increasing the number of bolt holes directly communicating with the display unit 110. Therefore, the display unit 110 can only be fixed by relying on the machining precision of the protective frame 121, the display unit 110, and the protective back cover 123 themselves, as well as their mutual assembly precision, to achieve mutual contact.

[0083] However, due to processing and assembly tolerances, the assembly gaps 1215 between the protective frame 121 and the display unit 110, and between the protective back cover 123 and the display unit 110, cause the display device 100 to have technical problems such as the inability to fix the display unit 110 in the vertical, horizontal, and front-back directions of the accommodating cavity, and the display unit 110 will collide with the protective frame 121 or the protective back cover 123 when it is displaced in the accommodating cavity, resulting in poor stability and poor sealing between the internal structural components of the display device 100.

[0084] To address the aforementioned technical problems, this application provides further improvements to the display device 100.

[0085] It should be noted in advance that, standing on the display side of the display device 100, the left and right direction of the display device 100 is the first direction, the up and down direction of the display device 100 is the second direction, and the thickness direction of the display device 100 is the third direction. Both the first and second directions are perpendicular to the third direction.

[0086] In other embodiments, such as Figure 6 , Figure 7 and Figure 8 As shown, the display device 100 includes a display unit 110. The display unit 110 includes a display module 111, a module bezel 112, and an elastic member 113. (As shown...) Figure 9 As shown, the module frame 112 surrounds the outer periphery of the display module 111 to protect the display module 111; combined with Figure 8 , Figure 10 and Figure 11 As shown, the elastic element 113 is connected to the module frame 112 and extends circumferentially along the module frame 112, and the outer peripheral surface of the elastic element 113 protrudes from the outer peripheral wall of the module frame 112.

[0087] For example, the elastic element 113 is at least one of a spring, a sheet, a silicone element, or a rubber element, so that the elastic element 113 has the functions of flexible buffering, error compensation, and stable constraint. The following description uses a silicone strip as an example of the elastic element 113.

[0088] It should be noted that the shape of the module frame 112 matches that of the display module 111. Taking the display module 111 as an example, the module frame 112 is a square ring-shaped integrated structure.

[0089] And such as Figure 11 and Figure 12 As shown, the outer peripheral wall of the module frame 112 has a circumferentially extending limiting groove 1121. The opening of the limiting groove 1121 faces the side facing the protective frame 121. An elastic member 113 is disposed in the limiting groove 1121, and the end of the elastic member 113 facing the protective frame 121 protrudes from the opening of the groove. The limiting groove 1121 is provided to limit and fix the elastic member 113, improve the stability of the elastic member 113 relative to the module frame 112 during the assembly of the display unit 110, and prevent the elastic member 113 from shifting or falling out.

[0090] Furthermore, such as Figure 11 and Figure 12 As shown, both sides of the slot have limiting flanges 1122 extending towards the center of the slot, and a clearance notch 1123 is formed between the limiting flanges 1122 on both sides. The elastic member 113 includes a connecting part 1131 and an abutting part 1132 connected to each other. The connecting part 1131 is disposed in the limiting slot 1121, and the abutting part 1132 passes through the clearance notch 1123 and protrudes from the outer peripheral wall of the module frame 112. Figure 11 and Figure 13 As shown, the cross-sectional width of the connecting part 1131 is greater than the cross-sectional width of the abutting part 1132. In this way, the connecting part 1131 can be engaged with the limiting flange 1122, so that the limiting flange 1122 limits and fixes the connecting part 1131 of the elastic member 113, thereby further improving the stability and reliability of the elastic member 113 relative to the module frame 112, and further preventing the elastic member 113 from shifting or falling out of the limiting groove 1121.

[0091] It should be noted that, as Figure 7 and Figure 8 As shown, the elastic element 113 in the display device 100 includes a plurality of silicone strips. For example, the number of sides of the module frame 112 is the same as the number of silicone strips. In this way, each silicone strip can be inserted into the limiting groove 1121 from the corner of the module frame 112 along the extension direction of the limiting groove 1121, which is simple and convenient to operate.

[0092] In addition, such as Figure 6 and Figure 15As shown, the display device 100 also includes a housing assembly 120, which includes a protective frame 121 surrounding the outer periphery of the display unit 110. Figure 14 , Figure 16 and Figure 17 As shown, an assembly gap 1215 is formed between the inner wall of the protective frame 121 and the outer peripheral wall of the corresponding side module frame 112. The elastic element 113 is located within the assembly gap 1215 and abuts against the inner wall of the protective frame 121 to restrict the movement of the display unit 110 in the first and second directions, so that the display unit 110 can be fixed relative to the protective frame 121 in the up-down and left-right directions.

[0093] In this embodiment, by providing a circumferentially extending elastic member 113 on the outer wall surface of the module frame 112 of the display module 111, the display unit 110 abuts against the inner peripheral wall of the protective frame 121 through the elastic member 113, filling the assembly gap 1215 between the display unit 110 and the protective frame 121. This compensates for the assembly gap 1215 caused by the processing or installation errors of the protective frame 121 and the display unit 110, so that the display unit 110 is fixed relative to the protective frame 121 in the first and second directions. This improves the fixing reliability of the display unit 110 in the first and second directions, avoids displacement of the display unit 110 in the first and second directions, and prevents collision between the display unit 110 and the protective frame 121 that could cause the display device 100 to fail to seal, thereby improving the stability and sealing of the display device 100.

[0094] In some embodiments, such as Figure 15 and Figure 17 As shown, the display device 100 also includes a protective glass 140, which is disposed on the display side of the display unit 110 and is fixedly and sealed to the protective frame 121. For example, the protective glass 140 and the protective frame 121 are bonded together.

[0095] The protective glass 140 has a screen-printed ink layer on the edge opposite to the display unit 110, so that the area formed by the screen-printed ink layer on the protective glass 140 corresponds to the display area of ​​the display unit 110. The screen-printed ink layer covers the protective frame 121 and other structural components in the non-display area of ​​the display unit 110, thereby improving the display aesthetics and visual experience of the display device 100.

[0096] The outer wall of the display module 111 frame 112 is provided with a circumferentially extending elastic element 113, which fills the assembly gap 1215 between the two. The display unit 110 abuts against the protective frame 121 through the elastic element 113, and a circumferential flexible constraint is formed between the display unit 110 and the protective frame 121. When the display unit 110 has a tendency to shift in the first direction or the second direction, the elastic element 113 in the shift direction is compressed by force, forming a rebound force. Under the action of the rebound force, the display unit 110 is supported to move back in the opposite direction until the display unit 110 is balanced by the force in the first direction and the second direction. The display area of ​​the display unit 110 is restored to the center setting, that is, the display area of ​​the display unit 110 corresponds to the area formed by the screen printing ink layer of the protective glass 140. Therefore, the elastic element 113 ensures that even with an assembly gap 1215 between the protective frame 121 and the display unit 110, the display unit 110 will remain centered under the action of the elastic element 113. This compensates for positional deviations caused by processing or installation errors, thereby improving the stability and reliability of the display unit 110 relative to the protective frame 121, while also enhancing the aesthetics and visual experience of the display device 100. This also reduces the display device 100's dependence on processing precision and lowers processing difficulty.

[0097] Furthermore, the elastic element 113 makes the fit between the display unit 110 and the protective frame 121 flexible, making the fit smoother and facilitating the disassembly and assembly of the display unit 110.

[0098] In addition, such as Figure 18 , Figure 19 and Figure 20 As shown, the display device 100 also includes a plurality of fixed brackets 122. Along the thickness direction of the display unit 110, each fixed bracket 122 is disposed on the side of the display unit 110 away from its display side, and the plurality of fixed brackets 122 are arranged circumferentially at intervals along the edge of the display unit 110. One end of each fixed bracket 122 is connected to the protective frame 121, and the other end is connected to the display unit 110.

[0099] It should be noted that the number of fixed brackets 122 can be four, six, eight, ten, etc., for example... Figure 20 As shown, the dimensions of each fixing bracket 122 in its extension direction, i.e., its length, can be different to accommodate the lengths of each side of the protective frame 121. Of course, each side of the protective frame 121 has at least one corresponding fixing bracket 122.

[0100] For example, in combination Figure 17 and Figure 19As shown, the protective frame 121 has a first limiting structure 1211 on the side facing the fixed bracket 122, and each fixed bracket 122 has a second limiting structure 1221 adapted to the first limiting structure 1211. The first limiting structure 1211 has a first limiting surface 1212, and the second limiting structure 1221 has a second limiting surface 1222. The first limiting surface 1212 and the second limiting surface 1222 abut against each other in the thickness direction of the display unit 110 to restrict the movement of the display unit 110 in its own thickness direction, thereby fixing the display unit 110 relative to the protective frame 121 in its thickness direction, i.e., the third direction, to improve the fixing reliability of the display unit 110 in the third direction.

[0101] In some specific embodiments, such as Figure 17 and Figure 19 As shown, the first limiting structure 1211 is a limiting groove, and the second limiting structure 1221 is a limiting protrusion. The structure is simple and easy to snap on. For example, the limiting groove extends circumferentially on the side of the protective frame 121 facing the fixed bracket 122 to facilitate processing and manufacturing.

[0102] The limiting protrusion has an inclined angle between its surface in the thickness direction and the thickness direction of the display unit 110, forming a first limiting surface 1212. The limiting groove has an inclined angle on its wall surface in the thickness direction of the display unit 110, which is on the same side as the first limiting surface 1212, forming a second limiting surface 1222. The arrangement of the first limiting surface 1212 and the second limiting surface 1222 with inclined angles to the thickness direction of the display unit 110 makes the fit between the limiting protrusions of each fixing bracket 122 and the limiting grooves of the protective frame 121 smoother and more efficient, making the installation of each fixing bracket 122 more convenient and labor-saving.

[0103] Furthermore, the contact between the first limiting surface 1212 of the first limiting structure 1211 on the protective frame 121 and the second limiting surface 1222 of the second limiting structure 1221 on each fixed bracket 122 causes one end of each fixed bracket 122 facing the display unit 110 to contact the display unit 110. Combined with the connection between each fixed bracket 122 and the display unit 110, the display unit 110 is fixed relative to the protective frame 121 in the third direction, thereby improving the fixing reliability of the display unit 110 in the third direction.

[0104] One example is that the connection between each fixed bracket 122 and the back plate 114 of the display unit 110 module is a detachable connection. The detachable connection method includes, but is not limited to, bolt and screw hole connection, snap-fit ​​connection, pin connection, etc. Another example is that the angle between the first limiting surface 1212 and the second limiting surface 1222 and the side of the display unit 110 away from its display side pointing towards the display side ranges from 0° to 90°, specifically, the angle is 30°, 45°, 60°, 75°, etc.

[0105] In this embodiment, a circumferentially extending elastic member 113 is provided on the outer wall surface of the module frame 112 of the display module 111 to fix the display unit 110 relative to the protective frame 121 in the first and second directions. Combined with the provision of multiple fixing members, the display unit 110 is fixed relative to the protective frame 121 in the third direction, thereby fixing the display unit 110 relative to the protective frame 121 in the up-down, left-right, and front-back directions, improving the fixing reliability and stability of the display device 100. Simultaneously, it prevents the display device 100 from shifting within the protective frame 121, thus preventing collisions between the display unit 110 and the protective frame 121, protecting the display unit 110 while improving the sealing performance between the display unit 110 and the protective frame 121.

[0106] In addition, such as Figure 21 , Figure 22 and Figure 23 As shown, the housing assembly 120 also includes a protective rear cover 123, which is disposed on the side of the display unit 110 opposite to its display side and is connected to the protective frame 121. The protective rear cover 123 is provided to improve the protective performance of the display device 100 on its rear side.

[0107] Among them, such as Figure 20 As shown, the protective back cover 123 and each fixed bracket 122 have elastic arms 1231 at corresponding positions, such as... Figure 22 As shown, along the thickness direction of the vertical display unit 110, each fixed bracket 122 is located between the elastic arm 1231 and the protective frame 121. The elastic arm 1231 abuts against the fixed bracket 122 so that the limiting protrusion always has a tendency to move into the limiting groove, thereby preventing the limiting protrusion from coming out of the limiting groove. This improves the connection accuracy between each fixed bracket 122 and the protective frame 121, improves the positional accuracy of the fixed bracket 122, and further improves the reliability of the display unit 110 being fixed relative to the protective frame 121 in the third direction.

[0108] It should be noted that one end of each fixed bracket 122 is connected to the protective frame 121 by a limiting groove and a limiting protrusion. The end of each fixed bracket 122 facing the display unit 110 is detachably connected to the display unit 110. Thus, this solution has limited the display unit 110 relative to the protective frame 121 in the third direction. However, considering that there may be processing or installation errors in the connection position between each fixed bracket 122 and the display unit 110, there is a phenomenon that the first limiting surface 1212 and the second limiting surface 1222 between the limiting groove and the limiting protrusion are not tightly fitted, resulting in unreliable fixation of the display unit 110 in the third direction. Therefore, an elastic arm 1231 is provided so that, under the action of its own elastic properties, the elastic arm 1231 provides each fixed bracket 122 with a force in the direction of its limiting protrusion toward the limiting groove, so that the limiting protrusion always tends to move into the limiting groove, and the first limiting surface 1212 is always in close contact with the second limiting surface 1222, thereby improving the connection accuracy between each fixed bracket 122 and the protective frame 121, improving the positional accuracy of the fixed bracket 122, and thus improving the reliability of the display unit 110 fixed relative to the protective frame 121 in the third direction.

[0109] For example, the number of elastic arms 1231 can be ten, sixteen, twenty, twenty-six, thirty, etc., and the multiple elastic arms 1231 are distributed at positions corresponding to each fixed bracket 122. Among them, along the length direction of each fixed bracket 122, each end of each fixed bracket 122 abuts against at least one elastic arm 1231.

[0110] In some specific embodiments, such as Figure 19 or Figure 22 As shown, each elastic arm 1231 includes a support arm 1232 and an abutment arm 1233 connected in sequence. The end of the support arm 1232 away from the abutment arm 1233 is fixedly connected to the protective rear shell 123. The end of the abutment arm 1233 away from the support arm 1232 abuts against the corresponding fixed bracket 122. There is an included angle between the support arm 1232 and the abutment arm 1233. The support arm 1232 is provided to provide a supporting force to the corresponding fixed bracket 122. The abutment arm 1233 is provided to increase the contact area with the corresponding fixed bracket 122 and improve the elastic performance of the elastic arm 1231 itself. It provides deformation to compensate for the positional deviation between the limiting groove and the limiting protrusion caused by the processing error of the limiting groove and the limiting protrusion. This reduces the manufacturing difficulty of the protective frame 121 and each fixed bracket 122 while ensuring the assembly accuracy between the protective shell, the fixed bracket 122 and the protective frame 121.

[0111] For example, the included angle between the abutment arm 1233 and the support arm 1232 is 90°, which facilitates processing and manufacturing.

[0112] In some embodiments, combined with Figure 19 , Figure 20 , Figure 22 and Figure 23 As shown, the protective back cover 123 has a connecting seat 1234, which is connected to the display unit 110 and provides a fixed fulcrum for the elastic arm 1231. The connecting seat 1234 and the elastic arm 1231 are an integral structure, simplifying manufacturing and reducing assembly errors. The other parts of the protective back cover 123 can be fixedly connected to the connecting seat 1234, or they can be separate, meaning the connecting seat 1234 is independent of the other parts of the protective back cover 123. The connecting seat 1234 in the protective back cover 123 is not specifically limited in this embodiment.

[0113] For example, the connector 1234 and the display unit 110 are detachably connected. Specifically, the connector 1234 and the module back plate 114 of the display unit 110 are detachably connected. The detachable connection methods include, but are not limited to, bolt and screw hole connection, snap-fit ​​connection, pin connection, etc.

[0114] In addition, such as Figure 22 As shown, the protective frame 121 has a mounting groove 1213 extending circumferentially on the side facing the protective back cover 123. The display device 100 also includes a sealing element 130, which is disposed in the mounting groove 1213 to seal the gap between the protective frame 121 and the protective back cover 123, preventing dust, moisture, etc. from entering the display unit 110 from the gap between the protective back cover 123 and the protective frame 121, affecting the display performance of the display unit 110, thereby further improving the sealing performance and sealing reliability of the display device 100.

[0115] For example, the seal 130 adopts an integrated sealing ring, and the material of the sealing ring can be silicone rubber, EPDM rubber, fluororubber, nitrile rubber, etc.

[0116] Combination Figure 19 and Figure 22 As shown, the protective frame 121 has a positioning groove 1214 extending circumferentially on the side facing the protective back cover 123, and the protective back cover 123 has a positioning protrusion 1235 extending circumferentially. The positioning groove 1214 matches the positioning protrusion 1235, thereby improving the installation accuracy and efficiency between the protective frame 121 and the protective back cover 123.

[0117] The mounting groove 1213 is located on the side of the positioning groove 1214 near the fixed bracket 122, so that dust and moisture in the external environment are first blocked by the positioning groove 1214 and the positioning protrusion 1235, and then sealed by the sealing element 130 in the mounting groove 1213, providing double protection and reducing the aging rate of the sealing element 130, thereby further improving the sealing performance and reliability of the display device 100.

[0118] In addition, combined Figure 19 , Figure 22 and Figure 23 As shown, the protective back cover 123 and each fixed bracket 122 are detachably connected. The protective back cover 123 has through holes at corresponding positions on each fixed bracket 122. Each fixed bracket 122 has a threaded hole 151 on the side facing the protective back cover 123. The display device 100 also includes multiple threaded connectors 150, each threaded connector 150 passing through the through hole and threadedly connected to the corresponding threaded hole 151. For example, the threaded connector 150 is a bolt, and a sealing washer is provided between the nut of the bolt and the protective back cover 123 to improve the sealing performance and reliability between the protective back cover 123 and each fixed bracket 122.
