[0040] As described in the background section, display devices in related technologies, such as LED display devices, typically include multiple interconnected display units, and each display unit is equipped with a display panel. The display panel includes a display surface and a non-display surface opposite to the display surface. A panel base and a housing are sequentially arranged on one side of the non-display surface of the display panel. The panel base is connected between the display panel and the housing. While the housing supports and fixes the display panel, the control card and power card inside the housing are connected to the display panel in the display unit via wires. The power card can supply power to the display panel, and the control card can control and light up the display panel in the display unit to display the image.

[0041] The display unit housings can be spliced ​​together to form display devices of different sizes.

[0042] However, the presence of the enclosure results in a relatively large thickness for the display unit, which is not conducive to making the display unit and display device thinner and lighter.

[0043] In view of this, the present application provides a display unit and a display device. Firstly, by setting up a display lamp panel and a lamp panel base shell in the display unit, the display lamp panel is located on a first mounting surface and detachably connected to the lamp panel base shell. Thus, one or more display lamp panels can be fixed by the lamp panel base shell, forming a display unit with a relatively large size. Next, a cover plate in the display unit covers the second mounting surface of the lamp panel base shell, forming a closed mounting cavity. An integrated board is housed within the mounting cavity and interlocks with the display lamp panel. This further improves the structure of the lamp panel base shell, not only enabling the installation of the integrated board on the base shell and facilitating power supply and control of the display lamp panel to ensure the display function of the display unit, but also effectively simplifying the internal wiring connections of the display unit and reducing display unit malfunctions. Therefore, the display unit of this application reduces the amount of housing in the display unit. While ensuring the display function of the display unit, it not only reduces the thickness of the display unit, which is beneficial for the thinner and lighter design of the display device, but also simplifies the internal wiring connections of the display unit, improving the safety and protection of both the display unit and the display device.

[0044] The structure of the display device according to the embodiments of this application will be further described below with reference to the accompanying drawings.

[0045] Example

[0046] Figure 1This is an installation diagram of a display unit provided in an embodiment of this application.

[0047] refer to Figure 1 As shown, the display unit 100 may include a display lamp panel 40, a lamp panel base shell 10, an integrated board 20, and a cover plate 30. The lamp panel base shell 10 has a first mounting surface 11 and a second mounting surface 12 opposite to the first mounting surface 11. The first mounting surface 11 can be understood as the front side of the lamp panel base shell 10, and the second mounting surface 12 can be understood as the back side of the lamp panel base shell 10. The cover plate 30 may be made of plastic or metal. The display unit 100 may be, but is not limited to, an LED display unit. When the display unit 100 is an LED display unit, the display lamp panel 40 may also be referred to as an LED lamp panel.

[0048] like Figure 1 As shown, the display lamp panel 40 is located on the first mounting surface 11 and is detachably connected to the lamp panel base shell 10. By increasing the size of the lamp panel base shell 10, one or more display lamp panels 40 can be fixed within it, thus forming a larger display unit 100 compared to display units in related technologies. In this embodiment, the lamp panel base shell 10 can be understood as a bracket or support structure.

[0049] It should be noted that the display unit 100 in this embodiment is an indoor display unit, and correspondingly, the display device is an indoor display device. When there are multiple display light panels 40, the multiple display light panels 40 can be spliced ​​together and fixed to the first mounting surface 11. This can improve the assembly efficiency of the display unit 100, facilitate the installation of the display device, and help ensure the flatness of the entire display screen.

[0050] The cover plate 30 covers the second mounting surface 12 and forms a closed mounting cavity 121 with the lamp panel base shell 10. The integrated board 20 is housed in the mounting cavity 121 and is interlocked with the display lamp panel 40. By further improving the structure of the lamp panel base shell 10, the integrated board 20 can be housed in the mounting cavity 121 formed by the cover plate 30 and the lamp panel base shell 10 and interlocked with the display lamp panel 40. Thus, the integrated board 20 provides power and control to the display lamp panel 40 to ensure the display function of the display unit 100.

[0051] Meanwhile, by covering the second mounting surface 12 of the lamp panel bottom shell 10 with the cover plate 30, and forming a closed mounting cavity 121 with the lamp panel bottom shell 10, the integrated board 20 can be installed on the lamp panel bottom shell 10. This makes the lamp panel bottom shell 10 and the cover plate 30 form a closed structure, which can prevent the integrated board 20 from being exposed to the outside of the display device. This serves to prevent fire, foreign objects, insects and rodents, thereby improving the safety and protection of the display unit 100 and the display device. At the same time, it can also ensure that the display device can meet the electromagnetic compatibility (EMC) requirements of the display unit 100, so as to meet the safety specifications (i.e., safety regulations) and aesthetics of the display unit 100.

[0052] Meanwhile, since the integrated board 20 and the display light board 40 are plugged into each other, a wireless connection between the integrated board 20 and the display light board 40 is achieved. This allows the integrated board 20 to power and control the display light board 40, ensuring the display function of the display unit 100. Compared with the wired connection between the control card and power card inside the cabinet and the display light board in related technologies, this embodiment can also effectively simplify the internal wiring connection of the display unit 100, reduce the failure of the display unit 100, facilitate the installation and maintenance of the display unit 100 and the display device, and improve the safety performance, reliability performance and installation efficiency of the display unit 100.

[0053] Therefore, compared with the display units in related technologies, the display unit 100 of this application improves the structure of the lamp board bottom shell 10 and sets up an integrated plate 20 and a cover plate 30. While ensuring the display function of the display unit 100, it not only reduces the structural design of the cabinet in the display unit 100 and reduces the thickness of the display unit 100, making the display unit 100 and the display device thinner and lighter, but also simplifies the internal wiring connection of the display unit 100 and improves the safety and protection of the display unit 100 and the display device.

[0054] refer to Figure 1 As shown, the side of the display panel 40 facing away from the base shell 10 forms the display surface of the display unit 100, facilitating the display of images or information. The side of the display panel 40 connected to the base shell 10 is the non-display surface 41, and the first mounting surface 11 covers the non-display surface 41. The display unit 100 can be configured as follows... Figure 1 The display unit 100 may have one or more display light panels 40. In this embodiment, the number of display light panels 40 in the display unit 100 is not further limited. This allows the base shell 10 of the light panel to have a larger size, so as to enable the fixing of the display light panels 40 in the display unit 100, thereby preventing the peripheral edges of the display light panels 40 from protruding and being exposed outside the base shell 10, and improving the assembly efficiency of the display unit 100.

[0055] Figure 2 This is a schematic diagram of the structure of a lamp panel base shell on the first mounting surface provided in an embodiment of this application.

[0056] To facilitate the detachable connection between the display light panel 40 and the light panel base 10, refer to Figure 2 As shown, the first mounting surface 11 has multiple mounting holes 13 for fasteners to pass through. These fasteners may include, but are not limited to, screws, bolts, or other structural components that can be inserted into the mounting holes 13 to connect the display light panel 40 and the base shell 10. The fasteners can pass through the mounting holes 13 and connect the display light panel 40 and the base shell 10, thereby achieving a detachable connection between the display light panel 40 and the base shell 10, and fixing the display light panel 40 to the first mounting surface 11 of the base shell 10.

[0057] Figure 3 This is a schematic diagram showing the location of the connection holes on a display light panel according to an embodiment of this application.

[0058] Accordingly, refer to Figure 3 As shown, the display panel 40 is also provided with connecting holes 42 for fastener connection. Fasteners can pass through the first mounting surface 11 of the base shell 10 of the display panel sequentially into the mounting holes 13 and connecting holes 42, connecting the display panel 40 and the base shell 10. The display panel 40 has multiple LED beads 44. Each LED bead 44, when lit, can be considered a pixel. By adjusting the distance between the centers of two adjacent LED beads 44, display panels 40 with different pixel pitches can be formed. The pixel pitch can be understood as the distance between the center lines of two adjacent LED beads 44 on the display panel 40. (Reference) Figure 3 As shown, the connection hole 42 can be located at the center between several (e.g., four) adjacent LED beads 44 on the display light panel 40. This ensures that the display light panel 40 is fixed to the base shell 10 of the light panel by fasteners, while preventing the connection hole 42 from damaging the circuit inside the display light panel 40.

[0059] like Figure 2 As shown, the mounting hole 13 can be located on the first mounting surface 11 corresponding to the portion of the display lamp panel 40 in the display unit 100, so as to realize the connection between the display lamp panel 40 and the lamp panel base shell 10. The mounting hole 13 can be located on the peripheral edge of the lamp panel base shell 10, inside the mounting cavity 121, and in the area between the mounting cavity 121 and the peripheral edge. The location and number of mounting holes 13 can be appropriately adjusted according to the number and size of the display lamp panels 40 in the display unit 100. In this embodiment, the location of the mounting hole 13 is not further limited.

[0060] Figure 4 yes Figure 2 Enlarged view of the bottom shell of the central lamp panel in part A.

[0061] In some embodiments, reference Figure 4 As shown, the mounting hole 13 can be a set of mounting hole structures consisting of a first through hole and a second through hole. The first through hole and the second through hole are arranged adjacent to each other on the lamp panel bottom shell 10 and connected to each other so that fasteners can pass through the first through hole or the second through hole and connect with the connection hole 42 at the same position as the display lamp panel 40. While realizing the connection between the display lamp panel 40 and the lamp panel bottom shell 10, the lamp panel bottom shell 10 can be compatible with display lamp panels 40 with different dot pitches.

[0062] Alternatively, in some other embodiments, the mounting holes 13 may be a group of mounting holes 13 consisting of a larger number of through holes. In this embodiment, the structure of the mounting holes 13 is not further limited. Alternatively, in some embodiments, the display light panel 40 may also be connected to the light panel base shell 10 by other detachable methods, such as snap-fit. In this embodiment, the connection method between the display light panel 40 and the light panel base shell 10 is not further limited.

[0063] Figure 5 This is a schematic diagram of the structure of a lamp panel base shell on the second mounting surface provided in an embodiment of this application.

[0064] refer to Figure 5 As shown, the second mounting surface 12 has a plurality of first recesses 123, each corresponding to a mounting hole 13, which is located within the first recess 123. When the fastener passes through the mounting hole 13 and connects to the display lamp panel 40, at least a portion of the fastener's end structure can be embedded in the first recess 123. This prevents the fastener from affecting the flatness of the display unit 100 on the second mounting surface 12 while simultaneously fixing the display lamp panel 40 to the lamp panel base shell 10, thus ensuring better flatness of the display unit 100 on the second mounting surface 12.

[0065] refer to Figure 5 As shown, the first recess 123 can be a groove recessed on the second mounting surface 12 towards the first mounting surface 11, wherein the groove constituting the first recess 123 can be defined as a first groove. In some embodiments, the bottom of the first groove can be higher than the first mounting surface 11. This can enhance the connection strength of the display lamp panel 40 on the display base.

[0066] refer to Figure 5 As shown, the second mounting surface 12 has a plurality of second recesses 124, which can be located on both sides of the mounting cavity 121, with a portion of the first recess 123 located within the second recesses 124. This allows the ends of fasteners not embedded in the first recesses 123 to be completely embedded within the second recesses 124, further improving the flatness of the display unit 100 on the second mounting surface 12.

[0067] refer to Figure 5 As shown in Figure 3, the second recess 124 can be a groove recessed on the second mounting surface 12 towards the first mounting surface 11, wherein the groove constituting the second recess 124 can be defined as the second groove. In some embodiments, the bottom of the second groove can be higher than the first mounting surface 11. In this way, the second recess 124 can form a rib-like structure on the first mounting surface 11, which, while ensuring that the display unit 100 has good flatness on the second mounting surface 12, can enhance the structural strength of the lamp base shell 10, thereby improving the stability of the display unit 100 structure.

[0068] In one possible implementation, refer to Figure 5 As shown in Figure 3, the second recessed portion 124 may include a first recessed segment 1241, a second recessed segment 1242, and a third recessed segment 1243. The first recessed segment 1241 may be parallel to the third recessed segment 1243, and the second recessed segment 1242 may be vertically connected between the first recessed segment 1241 and the third recessed segment 1243. In some embodiments, the second recessed segment 1242 may be vertically connected to the side where both the first recessed segment 1241 and the second recessed segment 1242 face the mounting cavity 121. In this case, the first recessed segment 1241, the second recessed segment 1242, and the third recessed segment 1243 may form a configuration as shown in Figure 3. Figure 5 The second recess 124, which is "C" shaped as shown, is used to form a rib-like structure with a "C" shaped structure on the first mounting surface 11.

[0069] Based on the second recessed segment 1242 mentioned above, with reference to Figure 5 Referring to Figure 3, the second recessed portion 124 may further include a fourth recessed segment 1244, which may be parallel to the first recessed segment 1241, and the end of the fourth recessed segment 1244 is connected to the second recessed segment 1242. In some embodiments, the fourth recessed segment 1244 may be located on the same side of the second recessed portion 124 as the first recessed portion 123 and the fourth recessed portion. In this case, the first recessed segment 1241, the second recessed segment 1242, the third recessed segment 1243, and the fourth recessed segment 1244 may form a configuration as shown in Figure 3. Figure 5 The "E"-shaped second recess 124 shown is used to form a ribbed structure with an "E" shape on the first mounting surface 11. Both the "C"-shaped and "E"-shaped second recesses 124 can coexist on the second mounting surface 12 and be spaced apart on the same side of the mounting cavity 121. This allows for efficient use of the structure of the lamp panel base shell 10, enabling more second recesses 124 to be provided on the second mounting surface 12. This results in better flatness of the second mounting surface 12 while simultaneously increasing the strength of the lamp panel base shell 10.

[0070] Alternatively, in some embodiments, the second recess 124 may be vertically connected to the side where both the first recess 1241 and the second recess 1242 are away from the mounting cavity 121. Alternatively, the fourth recess may be connected to the side of the second recess 124 opposite to the first recess 123. Alternatively, the second recess 124 may adopt other structures; in this embodiment, the structure of the second recess 124 is not further limited.

[0071] It should be noted that, in order to further enhance the structural strength of the lamp panel base shell 10, other reinforcing ribs may also be provided on the first mounting surface 11. In this embodiment, the structure of other reinforcing ribs is not further limited.

[0072] refer to Figure 5 As shown, the base shell 10 of the lamp panel can have a baffle 122 on the second mounting surface 12. The baffle 122 can surround the middle of the second mounting surface 12. The cover plate 30 covers the baffle 122 and together with the baffle 122 and the second mounting surface 12, they form a mounting cavity 121. In this way, the baffle 122, the cover plate 30, and the second mounting surface 12 together form an outwardly protruding mounting cavity 121 in the middle of the second mounting surface 12. This allows the integrated board 20 to be mounted on the base shell 10 so that the integrated board 20 can be stably inserted into the display lamp panel 40, avoiding exposure of functional units, while not affecting the thickness of the base shell 10 outside the mounting cavity 121, which helps to make the display unit 100 and the display device thinner and lighter.

[0073] To facilitate the assembly and disassembly of the integrated panel 20, the cover plate 30 can be detachably connected to the enclosure 122 via snap-fit, threaded, or other connection methods. In this embodiment, the cover plate 30 and the enclosure 122 are connected by a snap-fit ​​mechanism. (See reference...) Figure 5 As shown, the enclosure 122 has a snap-fit ​​portion 1224. For example, the snap-fit ​​portion 1224 may include, but is not limited to, a snap-fit ​​groove or a latching groove. This facilitates the cover plate 30 being fixed to the enclosure 122 by snap-fit.

[0074] Figure 6 This is a schematic diagram of the structure of a cover plate provided in an embodiment of this application.

[0075] refer to Figure 6 As shown, the cover plate 30 has a fastening element 32, and the engaging portion 1224 is disposed opposite to the fastening element 32 and engages with it. For example, the fastening element 32 may include, but is not limited to, an engagement point or a snap fastener. The engagement point may be located on one side of the cover plate 30 and connected to a slot. The snap fastener may be located on the side of the cover plate 30 facing the slot, so that the snap fastener can engage within the slot. This facilitates the connection between the cover plate 30 and the enclosure 122 while also allowing for the disassembly of the cover plate 30 and the maintenance of the integrated plate 20.

[0076] The mounting cavity 121 is provided with heat dissipation holes 31 and anti-slip grooves 1223. The heat dissipation holes 31 can, for example, allow for... Figure 6 As shown, the ventilation holes 31 are located on the cover plate 30, which facilitates gas convection and allows for sufficient heat dissipation from the integrated plate 20. Alternatively, the ventilation holes 31 can also be located on the enclosure 122. In this embodiment, the location and structure of the ventilation holes 31 are not further limited.

[0077] like Figure 5 As shown, in some embodiments, the lamp panel base shell 10 is also provided with a chamfer 15 on the peripheral edge of the second mounting surface 12, so as to reduce the thickness of the lamp panel base shell 10 at the peripheral edge by the chamfer 15, so that the display unit 100 and the display device have a smaller visual thickness.

[0078] refer to Figure 5 As shown, the base shell 10 of the lamp panel may also include multiple inserts 14, which can be configured as follows: Figure 5 The display unit 100 is embedded in the peripheral edge of the second mounting surface 12. The display unit 100 may also include a magnetic element 50, which, for example, may include, but is not limited to, a magnet or other magnetic structural component. The magnetic element 50 can be detachably connected to the insert 14, thereby fixing the magnetic element 50 to the second mounting surface 12.

[0079] In this embodiment, the insert 14 can be a threaded insert 14 or other structural form that can be detachably connected to the magnetic component 50. This simplifies the fixing of the magnetic component 50 on the second mounting surface 12 while achieving a detachable connection between the magnetic component 50 and the insert 14.

[0080] To facilitate the embedding of the insert 14 into the second mounting surface 12, the lamp panel base shell 10 may be, but is not limited to, made of injection-molded plastic. When manufacturing the lamp panel base shell 10 by injection molding, the insert 14 can be pre-embedded within the second mounting surface 12 along its periphery, so that after the lamp panel base shell 10 is injection-molded, the insert 14 can be directly embedded in the lamp panel base shell 10. After the lamp panel base shell 10 is formed, the magnetic component 50 can be directly secured to the insert 14 via threaded connection or other means.

[0081] Figure 7 and Figure 8 The diagram illustrates the structure of an integrated board from different viewpoints. Figure 7 This can be understood as a structural diagram of the front of the integrated board. Figure 8 This can be understood as a structural diagram of the back of the integrated board.

[0082] refer to Figure 7 and Figure 8As shown, the integrated board 20 has multiple functional modules, and the display unit 100 further includes a first connector 26 and a second connector 43. The first connector 26 can be located on the side of the integrated board 20 opposite to the functional modules and is electrically connected to the functional modules. The second connector 43 can be located on the display lamp panel 40, and the first connector 26 and the second connector 43 are interlocked. For example, the functional modules can be located on the front side of the integrated board 20, and the first connector 26 can be located on the back side of the integrated board 20. In this way, while ensuring that the integrated board 20 can be electrically connected to the display lamp panel 40 through the first connector 26, the thickness of the integrated board 20 and the display unit 100 can be reduced, so that the display unit 100 and the display device can be developed in the direction of thinner and lighter design.

[0083] To facilitate the connection between the integrated board 20 and the display light board 40, the bottom of the mounting cavity 121 is provided with a connection slot 1211 (e.g., Figure 5 As shown in the diagram, the insertion slot 1211 is arranged opposite to the first insertion member 26 and the second insertion member 43 so that one or both of the first insertion member 26 and the second insertion member 43 can be inserted through the insertion slot 1211 to realize the insertion of the integrated board 20 and the display lamp board 40, so that the integrated board 20 can be used to power and control the display lamp board 40.

[0084] It should be noted that when multiple display light panels 40 are provided in the display unit 100, multiple first connectors 26 can also be provided on the integrated board 20, and the multiple first connectors 26 correspond one-to-one with the second connectors 43 on the multiple display light panels 40 and are plugged into each other, so as to realize the plugging of the integrated board 20 with the multiple display light panels 40 in the display unit 100.

[0085] refer to Figure 7 As shown, the functional modules may include a power supply module 21, a control module 22, and a power supply connector module 23. The power supply connector module 23 is electrically connected to the control module 22 through the power supply module 21. The power supply connector module 23 can also be referred to as a power supply plug. The power supply connector module 23 is configured to transmit external current, such as mains voltage, to the power supply module 21. The power supply module 21 is configured to convert the external current from high voltage to low voltage before transmitting it to the control module 22 and the display panel 40, thereby supplying power to the control module 22 and the display panel 40 for their operation.

[0086] To enable the input of external drive signals, the functional module may include a signal connector module 24, which is electrically connected to the control module 22. The signal connector module 24 can also be referred to as a signal connector. The signal connector module 24 is configured to transmit external drive signals to the control module 22. The control module 22 is configured to drive the display panel 40 via the external drive signals to display the desired signal, thereby enabling the display device to perform its display function.

[0087] It should be noted that the signal connector module 24 can be connected to external devices to transmit external drive signals to the control module 22. After being processed by the control module 22, the signals are transmitted to the display panel 40 to drive the display panel 40 to display the required signal.

[0088] To facilitate the connection of the power supply connector module 23 and the signal connector module 24 to external devices, external current and external drive signals are transmitted to the integrated board 20, such as... Figure 5 As shown, the cavity wall of the mounting cavity 121 has a first wiring groove 1221 and a second wiring groove 1222. The first wiring groove 1221 is disposed opposite to the power supply connector module 23 so that the power supply connector module 23 can be electrically connected to external devices. The second wiring groove 1222 is disposed opposite to the signal connector module 24 so that the signal connector module 24 can be electrically connected to external devices. In this way, the arrangement of the first wiring groove 1221 and the second wiring groove 1222 facilitates the cascading of power supply, signal and control among multiple display units 100.

[0089] like Figure 7 As shown, the number of signal connector modules 24 on the integrated board 20 can be two, or other numbers. When there are two signal connector modules 24 in the connector assembly, one signal connector module 24 can be used as a signal input terminal, and the other signal connector module 24 can be used as a signal output terminal, which helps to realize the cascading of signals and controls between multiple display units 100.

[0090] refer to Figure 7 As shown, in some embodiments, the functional unit may further include a test module 25, which is electrically connected to the control module 22 so as to test the performance of the integrated board 20, such as the performance of the functional modules on the integrated board 20.

[0091] Based on the above embodiments, this application also provides a display device.

[0092] The structure of the display device will be further explained below with reference to the accompanying drawings.

[0093] Figure 9 and Figure 10 The diagrams show the overall and partial structures of a display device.

[0094] refer to Figure 9 As shown, the display device may include a metal fastener 300 and a display unit 100 as described above, wherein multiple display units 100 are spliced ​​together. Figure 1 The display device has eighteen display units 100. In some embodiments, the display device may have two, three, four, six, eight or more display units 100, so that display units 100 can be spliced ​​together to form display devices of different sizes.

[0095] refer to Figure 10 As shown, the metal fastener 300 is located at the splicing point 200 between two adjacent display units 100. Since the mounting cavity 121 is located in the middle of the display unit 100, the metal fastener 300 not only improves the stability of the display device at the splicing point 200, but also avoids interference between the metal fastener 300 and the integrated board 20, resulting in a thinner display device at the splicing point 200, which contributes to the thinning and lightening of the display device.

[0096] The metal fastener 300 can be disposed on the non-display surface 41 of the display unit 100, and along the length or width direction of the display device at the splicing point 200 of two adjacent display units 100, to support and further fix the display unit 100, thereby enhancing the stability of the display device. The length direction of the display device can be understood as... Figure 10 In the X direction, the width direction of the display device can be understood as... Figure 10 in the Y direction.

[0097] refer to Figure 10 As shown, in the extending direction perpendicular to the metal fastener 300, the cross-section of the metal fastener 300 is a hollow rectangle. The metal fastener 300 can be understood as a square tube. This allows the metal fastener 300 to support the display device at the splicing point 200 while reducing the weight of the display device, contributing to its trend towards thinner and lighter designs. Alternatively, in some embodiments, the cross-section of the metal fastener 300 can also be other hollow shapes, such as triangles, trapezoids, or other polygons. This allows for greater structural diversity in the metal fastener 300.

[0098] The magnetic component 50 of the display unit 100 can be attached to the metal fastener 300. Because of the magnetic component 50, no additional screws are needed for fastening, allowing for quick installation of the display unit 100 onto the metal fastener 300. This makes the metal fastener 300 convenient and quick to use, facilitating the installation, maintenance, and disassembly of the display device.

[0099] To facilitate the adsorption of the magnetic component 50 onto the metal fixing component 300, the metal fixing component 300 may be, but is not limited to, a metal component with good magnetic conductivity, and may be, but is not limited to, an ferrous metal component. This ensures the rapid installation and fixing of the display unit 100 on the metal fixing component 300.

[0100] Figure 11 yes Figure 10 An enlarged view of the display device in section C.

[0101] refer to Figure 10 and Figure 11 As shown, the display device may include multiple display units 100, with power supply connector modules 23 of the multiple display units 100 cascaded together, and signal connector modules 24 of the multiple display units 100 cascaded together. This enables the cascading of power supply, signal, and control among the multiple display units 100 within the display device, simplifying the interface between the display device and external devices, making the wiring within the display device more indirect, and facilitating the control of the multiple display units 100.

[0102] Figure 10 The diagram shows the cascading of power supply connector modules 23 between six display units 100 within the display device, and the cascading of signal connector modules 24. It should be noted that when the display device has multiple display units 100, the power supply connector modules 23 of all display units 100 within the display device can be cascaded, and the signal connector modules 24 can also be cascaded.

[0103] The structure of the display device will be further explained below, taking the cascading of six display units 100 within the display device as an example.

[0104] refer to Figure 10 and Figure 11 As shown, the power supply connector modules 23 of multiple display units 100 can be cascaded through multiple cascaded power lines 27, thereby cascading the power supply of multiple display units 100. Each display unit 100 is provided with a cascaded power line 27, which may include a main power line 271 and a branch power line 272. The main power lines 271 of multiple display units 100 are connected in series, and the branch power line 272 can be connected to the side of the main power line 271 facing the integrated board 20 and positioned opposite the power supply connector module 23, so that the branch power line 272 can be plugged into the power supply connector module 23 of the display unit 100 at its location. In this way, the power supply of multiple display units 100 can be cascaded through multiple cascaded power lines 27.

[0105] refer to Figure 10 and Figure 11As shown, the signal connector module 24 of multiple display units 100 can be cascaded through multiple cascaded signal lines 28, thereby realizing the signal cascading of multiple display units 100.

[0106] refer to Figure 10 and 11 As shown, multiple signal connector modules 24 within the display device can be sequentially connected in series via multiple cascaded signal lines 28. Specifically, signal connector modules 24 of adjacent display units 100 can be connected in series via a single cascaded signal line 28. For example, when a display unit 100 has two signal connector modules 24, each of the two modules can be connected in series with a signal connector module 24 in an adjacent display unit 100 via a single cascaded signal line 28. This enables signal cascading between display units 100 containing multiple signal connector modules 24. Simultaneously, two interface ends of the cascaded signal line 28 are reserved on the outside of the display device to facilitate connection of the display unit 100 to external devices.

[0107] It should be noted that other methods can also be used to cascade the power supply modules 23 of the multiple display units 100 and the signal modules 24 of the multiple display units 100.

[0108] It should be noted that when the integrated board 20 is connected to the second connector 43 on the display board 40 through the first connector 26 and conduction is achieved, the power supply, control and signal on the integrated board 20 can be transmitted through the first connector 26 and the second connector 43 on the display board 40.

[0109] The display unit 100 and display device provided in this application, through the arrangement of the display lamp board 40, the lamp board bottom shell 10, the integrated board 20 and the cover plate 30 in the display unit 100, can reduce the arrangement of the cabinet in the display unit 100. While ensuring the display function of the display unit 100, it can not only reduce the thickness of the display unit 100, which is conducive to the thinning of the display device, but also simplify the internal wiring connection of the display unit 100, and improve the safety and protection of the display unit 100 and the display device.
