Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a display module and a display screen. Background Technology

[0002] like Figure 1 As shown, a rental LED display screen generally includes a cabinet frame and several display modules 100' assembled on the cabinet frame. The size of the display modules 100' is usually 250mm×250mm, 250mm×500mm, 300mm×300mm, or 300mm×600mm. Multiple display modules 100' are spliced ​​together to form commonly used cabinet units. For example, the most commonly used cabinet sizes on the market are 500mm×500mm, 500mm×1000mm, 1000mm×1000mm, and 600mm×1200mm. It can be widely used in concerts, exhibitions, press conferences, celebrations, temporary stages, and other scenarios that require the short-term construction of large screens.

[0003] The display module 100' includes a PCB board and several LED beads mounted on the PCB board. The PCB board controls the LED beads to emit light, and each LED bead represents a pixel. As the pixel pitch decreases, the LED beads at the edge of the cabinet frame become increasingly closer to the physical edge of the cabinet frame. For example, with the commonly used P2.5mm pitch, if SMD1515 packaged LED beads are used, the LED beads closest to the edge are only 0.5mm away from the edge of the cabinet frame. Regardless of the material used to protect the edge of the cabinet frame, the LED beads near the edge of the cabinet frame are easily bumped or even damaged during frequent disassembly and assembly. Therefore, the display module needs to be frequently replaced to repair the LED beads, which not only requires more display module spare parts but also incurs higher labor costs for repairs, resulting in higher rental costs and reducing the efficiency and convenience of rental use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is: the existing rental LED display screens require frequent replacement of display modules for LED lamp bead maintenance, resulting in high rental costs and reduced efficiency and convenience of rental use. This utility model provides a display module and display screen.

[0005] To address the aforementioned issues, this utility model provides a display module, including a display panel. The display panel includes a main panel and one or more secondary panels, which are assembled onto the edge of the main panel. The width of the secondary panels is smaller than the width of the main panel. The main panel includes a main carrier board, and the secondary panel includes a secondary carrier board.

[0008] Optionally, the secondary panel includes a horizontal secondary panel, which is disposed on the upper and / or lower sides of the main panel. Alternatively, the secondary panel may include a vertical secondary panel, which is disposed on the left and / or right sides of the main panel. Alternatively, the secondary panel may include a corner secondary panel disposed at a corner of the display panel.

[0009] Optionally, the secondary panel includes a corner secondary panel, a vertical secondary panel, and a horizontal secondary panel; the vertical secondary panel is disposed on the left and / or right sides of the main panel; the horizontal secondary panel is disposed on the upper and / or lower sides of the main panel; the corner secondary panel is disposed between adjacent vertical and horizontal secondary panels and located at the corner of the display panel.

[0010] Optionally, the main panel includes multiple sub-panels, and the multiple sub-panels are assembled into the main panel.

[0011] Optionally, the display module further includes a base, and the display panel is mounted on the base.

[0012] Optionally, the back side of the secondary carrier board is electrically connected to the back side of the primary carrier board; Alternatively, the display module may further include an adapter board disposed on the bottom side of the main carrier board and the secondary carrier board, with the back side of the secondary carrier board and the back side of the main carrier board respectively electrically connected to the adapter board.

[0013] Optionally, the display module further includes a main connector, a first inter-board connector, and a second inter-board connector. The main connector and the first inter-board connector are mounted on the back of the main carrier board, and the second inter-board connector is mounted on the back of the secondary carrier board. The first inter-board connector is electrically connected to the second inter-board connector, and the first inter-board connector is electrically connected to the main connector through the main carrier board. The main connector is used to realize the power supply and communication of the display module.

[0014] Optionally, the lamp bead unit includes LED lamp beads without a built-in driver chip; a driver chip is mounted on the back of the display panel; or, The lamp bead unit includes LED lamp beads with built-in driver chips; the back of the display panel has no driver chip.

[0015] On the other hand, this utility model embodiment provides a display screen, including a cabinet frame, a power supply unit, a control unit, and a plurality of the above-mentioned display modules.

[0020] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] One embodiment of this utility model provides a display screen, such as... Figures 2 to 5 As shown, it includes a housing frame 200, a power supply unit, a control unit 300, and multiple display modules 100, with the display modules 100 electrically connected to the power supply unit and the control unit 300.

[0022] The display module 100 includes a display panel, which includes a main panel 1 and one or more secondary panels 2. The secondary panels 2 are assembled on the edge of the main panel 1. The width of the secondary panels 2 is smaller than the width of the main panel 1. The power supply unit can supply power to the display module 100. The control unit 300 can control the on / off state, brightness and color of the LED units 3 of the display module 100.

[0023] The main panel 1 includes a main carrier board 11, and the secondary panel 2 includes a secondary carrier board 21. Multiple LED units 3 are arrayed on the main carrier board 11 and the secondary carrier board 21.

[0024] Multiple display modules 100 are assembled on the front of the cabinet frame 200. The front of the cabinet frame 200 has an inner area and an edge area set around the outer side of the inner area. The main panel 1 of the multiple display modules 100 is assembled in the inner area, and the secondary panel 2 of the multiple display modules 100 is assembled in the edge area. Figure 3 The area within the dashed frame indicated by 'a' is the "internal area," and the area outside the dashed frame indicated by 'b' is the "edge area." In actual use, the "edge area" is the area most prone to bumps and knocks during the handling and disassembly of the display screen.

[0025] Specifically, the display panel of the entire display module 100 is assembled from a main panel 1 and at least one secondary panel 2. The LED units 3 on the main carrier board 11 of the main panel 1 and the LED units 3 on the secondary carrier board 21 of the secondary panel 2 can emit light and jointly realize the display function of the display panel.

[0026] Since the LED units 3 near the edge of the cabinet frame 200 of the display module 100 are easily damaged, the display panel is designed to be assembled from a main panel 1 and a secondary panel 2, which are separately set. The secondary panel 2, which is narrower than the main panel 1, is assembled on the side of the main panel 1 near the edge of the cabinet frame 200 of the display screen. In other words, the secondary panel 2 is set in the vulnerable area of ​​the display module 100 near the edge of the cabinet frame 200. When the LED unit 3 near the edge of the cabinet frame 200 is damaged, only the corresponding secondary panel 2 needs to be removed and replaced with a new one. The width of the secondary panel 2 is relatively small. Even if it is discarded directly, its cost will be much lower than the cost of manually repairing the LED unit 3. Moreover, no repair is required, which can greatly improve the efficiency and convenience of rental use.

[0027] When the secondary panel 2 is placed on the left or right side of the main panel 1, the width refers to the dimensions of the main panel 1 and the secondary panel 2 in the left-right direction; when the secondary panel 2 is placed on the top or bottom side of the main panel 1, the width refers to the dimensions of the main panel 1 and the secondary panel 2 in the top or bottom direction.

[0028] It should be noted that, Figure 4 The display shown includes only one cabinet frame 200. In actual use, multiple cabinet frames 200 can be assembled as needed, and multiple display modules 100 can be installed on each cabinet frame 200 to obtain a larger display screen.

[0029] In one embodiment, such as Figure 4 and Figure 5 As shown, the power supply unit includes a power supply box 400 and a power supply 500. The control unit 300 includes a control card. Both the control card and the power supply 500 are located inside the power supply box 400. The power supply box 400 is fixed to the back of the housing frame 200. The power supply 500 can supply power to the main carrier board 11 and the secondary carrier board 21 of each display module 100. The control card is signal connected to the main carrier board 11 and the secondary carrier board 21 of each display module 100 and is used to control the LED bead unit 3 on each display module 100 to emit light.

[0030] In one embodiment, the narrowest point of the width of the secondary panel 2 in one direction is 1mm to 60mm, so as to control the width of the secondary panel 2 and reduce the cost of replacing the secondary panel 2.

[0031] In one embodiment, the main panel 1 and the secondary panel 2 are rectangular. The LED units 3 on the main panel 1 are arranged in an N1-row * M1-column array. Each row of LED units 3 on the main panel 1 is spaced apart along the left-right direction of the display panel, and each column of LED units 3 on the main panel 1 is spaced apart along the top-bottom direction of the display panel. The LED units 3 on the secondary panel 2 are arranged in an N2-row * M2-row array. Each row of LED units 3 on the secondary panel 2 is spaced apart along the left-right direction of the display panel, and each column of LED units 3 on the secondary panel 2 is spaced apart along the top-bottom direction of the display panel. N2 or M2 of the secondary panel is 1~50. "*" represents the multiplication sign in mathematical operations. Figure 6 In this diagram, D1 represents the left-right direction of the display panel, and D2 represents the up-down direction of the display panel.

[0032] The sides of the rectangular main panel 1 extend in the same direction as the arrangement of the LED units 3 in each row or column. The sides of the rectangular secondary panel 2 extend in the same direction as the arrangement of the LED units 3 in each row or column. This avoids interference between the sides of the main panel 1 and the secondary panel 2 on the arrangement of the LED units 3 and improves the space utilization of the main panel 1 and the secondary panel 2.

[0033] Specifically, N2 or M2 is 2 to 5. In actual use, the 2 to 3 LED units 3 closest to the side edge of the cabinet frame 200 are most susceptible to impact. Therefore, the width of the secondary panel 2 should be 2 to 5 times the width of the LED units 3. This ensures that the display screen can be repaired by replacing the secondary panel 2 where the damaged LED units 3 are located, while further reducing the width of the secondary panel 2 and lowering the replacement cost.

[0034] In one embodiment, the secondary panel 2 includes a vertical secondary panel 22, which is disposed on the left and / or right sides of the main panel 1.

[0035] Specifically, such as Figure 6 The first type of display panel shown has a vertical secondary panel 22 located only on the left side of the main panel 1, combined with... Figure 2 The display screen shown has a 4-row, 2-column display module 100. The first type of display panel is assembled in the second and third rows of the left column of the cabinet frame 200, and the corresponding vertical sub-panel 22 is set near the left edge of the cabinet frame 200.

[0036] like Figure 6 As shown, the vertical secondary panel 22 is elongated and is a small, narrow panel near the edge of the display panel. The main panel 1 has N1 of 25 and M1 of 22, while the vertical secondary panel 22 has N2 of 25 and M2 of 3. Figure 6 In this diagram, A1 represents the width of the main panel 1, and B1 represents the width of the secondary panel 2.

[0037] like Figure 10The second type of display panel shown has a vertical secondary panel 22 located only on the right side of the main panel 1. In this case, combined with Figure 2 The display screen shown has a 4-row, 2-column display module 100. The second type of display panel is assembled in the second and third rows of the right column of the cabinet frame 200, and the corresponding vertical sub-panel 22 is set close to the right edge of the cabinet frame 200.

[0038] In the main panel 1, N1 is 25 and M1 is 22; in the vertical secondary panel 22, N2 is 25 and M2 is 3. Figure 10 In this diagram, A1 represents the width of the main panel 1, and B1 represents the width of the secondary panel 2.

[0039] In one embodiment, such as Figure 11 As shown, the secondary panel 2 includes a horizontal secondary panel 23, which is disposed on the upper and / or lower sides of the main panel 1.

[0040] In one embodiment, the secondary panel 2 includes a vertical secondary panel 22 and a horizontal secondary panel 23. The horizontal secondary panel 23 is disposed on the upper and / or lower sides of the main panel 1, and the vertical secondary panel 22 is disposed on the left and / or right sides of the main panel 1.

[0041] Specifically, such as Figure 11 The third type of display panel shown has a horizontal secondary panel 23 positioned below the main panel 1 in the vertical direction, and a vertical secondary panel 22 positioned to the right of the main panel 1 in the horizontal direction. (Combined with...) Figure 2 As can be seen from the display screen, the third display module 100 is assembled in the last row of the right column of the cabinet frame 200, the corresponding vertical sub-panel 22 is set near the right edge of the cabinet frame 200, and the corresponding horizontal sub-panel 23 is set near the lower edge of the cabinet frame 200.

[0042] like Figure 11 In the vertical sub-panel 22, N2 is 25 and M2 is 3, and in the horizontal sub-panel 23, N2 is 3 and M2 is 22. Figure 11 The B1 in the figure represents the width of the corresponding vertical sub-panel 22 and the width of the corresponding horizontal sub-panel 23.

[0043] After the LED unit 3 near the right edge of the display screen is bumped, the vertical sub-panel 22 of the third type of display panel can be directly replaced; after the LED unit 3 near the lower edge of the display screen is bumped, the horizontal sub-panel 23 of the third type of display panel can be directly replaced.

[0044] like Figure 12The fourth type of display panel shown has vertical secondary panels 22 positioned on either side of the main panel 1 in the left-right direction, and horizontal secondary panels 23 positioned on either side of the main panel 1 in the top-bottom direction. Both the vertical and horizontal secondary panels 22 and 23 are elongated, while the main panel and main panel 1 are square, thus assembling the main panel 1, vertical secondary panels 22, and horizontal secondary panels 23 into a square display panel. Specifically, in this fourth type of display panel, the main panel 1 has N2 of 19 and M2 of 19, the vertical secondary panel 22 has N2 of 25 and M2 of 3, and the horizontal secondary panel 23 has N2 of 3 and M2 of 19.

[0045] The secondary panel 2 is located on the outer periphery of the display panel, so that if any lamp bead unit 3 on the outer edge of the display panel is damaged, it can be repaired by replacing the corresponding secondary panel 2.

[0046] In one embodiment, the secondary panel 2 includes a corner secondary panel 24, which is disposed at the corner of the display panel.

[0047] In one embodiment, such as Figure 13 As shown, the secondary panel 2 includes a corner secondary panel 24, a vertical secondary panel 22, and a horizontal secondary panel 23; the vertical secondary panel 22 is located on the left and / or right sides of the main panel 1; the horizontal secondary panel 23 is located on the upper and / or lower sides of the main panel 1; the corner secondary panel 24 is located between the adjacent vertical secondary panel 22 and the horizontal secondary panel 23 and is located at the corner of the display panel.

[0048] Since the corners of the display panel are most susceptible to impacts, the LED units 3 near the corners are most easily damaged and require frequent replacement. In this application, multiple LED units 3 at the corners of the display panel are integrated into a corner sub-panel 24. The corner sub-panel 24 is set independently of the vertical sub-panel 22 and the horizontal sub-panel 23, so that the corner sub-panel 24 can be directly replaced after the LED units 3 at the corner are damaged, without having to replace the entire sub-panel 2. The corner sub-panel 24 is smaller in size to further reduce replacement costs.

[0049] Specifically, such as Figure 13 The fifth type of display module 100 shown has a vertical secondary panel 22 located on the right side of the left and right sides of the main panel 1, and a horizontal secondary panel 23 located on the lower side of the top and bottom sides of the main panel 1. Both the vertical secondary panel 22 and the horizontal secondary panel 23 are elongated, and the corner secondary panel 24 is square. The corner secondary panel 24 is located at the lower right corner of the display panel.

[0050] Among them, N2 is 22 and M2 is 22 for main panel 1, N2 is 22 and M2 is 3 for vertical secondary panel 22, N2 is 3 and M2 is 22 for horizontal secondary panel 23, and N2 is 3 and M2 is 3 for corner secondary panel 24.

[0051] The horizontal secondary panel 23, the vertical secondary panel 22, and the corner secondary panel 24 have regular shapes. The extension direction of the edge of each secondary panel 2 is the same as the arrangement direction of the LED bead unit 3 in each row or column, so as to avoid the edge of each secondary panel 2 interfering with the arrangement of the LED bead unit 3 and improve the space utilization of each secondary panel 2.

[0052] In other embodiments, the secondary panel 2 may include only four corner secondary panels 24, the main panel 1 is square, the corner secondary panels 24 may be right-angled triangles, the right-angled side of the corner secondary panel 24 is the side of the display panel, and the side of the main panel 1 is opposite to the hypotenuse of the corresponding corner secondary panel 24.

[0053] In one embodiment, such as Figure 14 As shown, the longitudinal sub-panel 22 includes multiple sub-longitudinal sub-panels, which are assembled to form the entire longitudinal sub-panel 22. This refines the replacement area corresponding to the entire longitudinal sub-panel 22 into smaller areas, so that only the sub-longitudinal panels in the corresponding areas need to be replaced, thereby reducing replacement costs and waste.

[0054] In one embodiment, such as Figure 14 As shown, the longitudinal sub-panel 22 includes a first sub-longitudinal sub-panel 221 and a second sub-longitudinal sub-panel 222, with the first sub-longitudinal sub-panel 221 assembled on top of the second sub-longitudinal sub-panel 222.

[0055] A single vertical sub-panel 22 is divided into a first sub-vertical sub-panel 221 and a second sub-vertical sub-panel 222, which are distributed vertically, to further refine the division of the edge area on one side. When the LED unit 3 in the area corresponding to the first sub-vertical sub-panel 221 is damaged, only the first sub-vertical sub-panel 221 needs to be replaced without replacing the entire vertical sub-panel 22. When the LED unit 3 in the area corresponding to the second sub-vertical sub-panel 222 is damaged, only the second sub-vertical sub-panel 222 needs to be replaced without replacing the entire vertical sub-panel 22, thereby further reducing the cost of replacing the sub-panel 2.

[0056] Specifically, such as Figure 14 The sixth type of display panel shown includes a secondary panel 2 comprising a vertical secondary panel 22 and a horizontal secondary panel 23. The vertical secondary panels 22 are disposed on both sides of the main panel 1 in the left-right direction. Each vertical secondary panel 22 includes a first sub-vertical secondary panel 221 and a second sub-vertical secondary panel 222 distributed vertically. The horizontal secondary panels 23 are disposed on both sides of the main panel 1 in the up-down direction.

[0057] In one embodiment, such as Figure 15As shown, a notch 223 extending through the thickness direction is provided on the side of the longitudinal secondary panel 22 near the main panel 1. The notch 223 has an opening facing the main panel 1. A protrusion 13 is provided on the side of the main panel 1 near the longitudinal secondary panel 22. The protrusion 13 protrudes towards the side near the longitudinal secondary panel 22 and is engaged with the notch 223, so that the main panel 1 and the longitudinal secondary panel 22 are mutually limited in the vertical direction, which facilitates the alignment and assembly of the main panel 1 and the longitudinal secondary panel 22 together.

[0058] Specifically, such as Figure 15 The seventh type of display panel shown has a main panel 1 and a secondary panel 2 that are irregularly shaped structures formed by variations on the traditional rectangular structure, yet they can still be assembled into a square display panel. The secondary panel 2 includes a vertical secondary panel 22 and a horizontal secondary panel 23. The vertical secondary panels 22 are located on both sides of the main panel 1 in the left-right direction, and the horizontal secondary panels 23 are located on both sides of the main panel 1 in the up-down direction. Each vertical secondary panel 22 has a notch 223 on the side closest to the main panel 1, and the main panel 1 has protrusions 13 on both the left and right sides. Figure 15 The B1 marked in the figure represents the width of the narrowest part of the vertical sub-panel 22.

[0059] In other embodiments, a notch may be provided at the edge of the main panel 1 near the secondary panel 2, and a protrusion may be provided on the side of the secondary panel 2 near the main panel 1, the protrusion protruding towards the side near the main panel 1, so that the protrusion is fitted into the notch.

[0060] In one embodiment, such as Figure 7 As shown, the display module 100 also includes a base 9, and the display panel is mounted on the base 9.

[0061] When assembling the display screen, the corresponding main panel 1 and secondary panel 2 can be assembled on the base 9 to form a display module 100. Then, multiple display modules 100 can be assembled on the cabinet frame 200 to form a display screen.

[0062] The base 9 enables the display panel, which is assembled from the main panel 1 and the secondary panel 2, to be independent and modular, which is conducive to the rapid assembly of multiple display modules 100 into a display screen, improving the system and expandability of the display screen.

[0063] In one embodiment, the base 9 includes a base plate 91 and a surrounding plate 92 disposed around the outer side of the base plate 91. The base plate 91 and the surrounding plate 92 enclose a mounting cavity 93 with an upward opening, and components on the back of the display panel can be placed in the mounting cavity 93.

[0064] In one embodiment, a support boss 94 protruding toward the display panel is provided on the base plate 91. The support boss 94 is provided at the splicing seam between the main panel 1 and the secondary panel 2. The support boss 94 supports the splicing side of the main panel 1 and the secondary panel 2 to improve the stability of the main panel 1 and the secondary panel 2 at the splicing point.

[0065] In one embodiment, the back side of the secondary carrier board 21 is electrically connected to the back side of the primary carrier board 11; Alternatively, the display module 100 may also include an adapter plate 7, which is disposed on the bottom side of the main carrier plate 11 and the secondary carrier plate 21, and the back of the secondary carrier plate 21 and the back of the main carrier plate 11 are electrically connected to the adapter plate 7 respectively.

[0066] In one embodiment, such as Figure 7 As shown, Figure 6 The first schematic diagram (A1-A1) shows that the display module 100 also includes a main connector 5, a first inter-board connector 4, and a second inter-board connector 6. The main connector 5 and the first inter-board connector 4 are mounted on the back of the main carrier board 11, and the second inter-board connector 6 is mounted on the back of the secondary carrier board 21. The first inter-board connector 4 and the second inter-board connector 6 are electrically connected. The first inter-board connector 4 is electrically connected to the main connector 5 through the main carrier board 11. The main connector 5 is used to realize the power supply and communication of the display module 100.

[0067] Specifically, the first board connector 4 is electrically connected to the second board connector 6 via an FPC flexible flat cable 8. The FPC flexible flat cable 8 has a first terminal portion and a second terminal portion. The first terminal portion is electrically connected to the first board connector 4, and the second terminal portion is electrically connected to the second board connector 6. The first board connector 4 is electrically connected to the main connector 5 via a main carrier board 11, so that the main connector 5 can realize power supply and communication between the main panel 1 and the secondary panel 2 of the display module 100.

[0068] The substrate of FPC flexible flat cable 8 has excellent flexibility and can be bent, which is conducive to flexible layout in small spaces.

[0069] In one embodiment, such as Figure 4 As shown, the display module 100 also includes a HUB board 600, which is installed inside the power supply box 400. The HUB board 600 is equipped with a power interface, an input interface, and an output interface. The control card of the control unit 300 is connected to the input interface for transmitting image data, control signals, etc., to the HUB board 600. The main connector 5 is connected to the output interface for outputting the signals processed and distributed by the HUB board 600 to each display panel, realizing signal cascading and expansion. The power supply 500 is connected to the power interface to provide power to the HUB board 600, control card, and display panels, ensuring their normal operation.

[0070] In other embodiments, such as Figure 8 As shown, Figure 6 In the second schematic diagram of A1-A1, the first inter-board connector 4 is electrically connected to the adapter board 7 facing the front of the main carrier board 11, and the second inter-board connector 6 is electrically connected to the adapter board 7 facing the front of the secondary carrier board 21. The main connector 5 is installed on the back of the adapter board 7 facing away from the main carrier board 11, so that the main connector 5 is electrically connected to the first inter-board connector 4 and the second inter-board connector 6 through the adapter board 7, so that the main connector 5 can realize the power supply and communication between the main panel 1 and the secondary panel 2 of the display module 100.

[0071] Of course, the main carrier board 11 and the secondary carrier board 21 can also be electrically connected to the adapter board 7 by means of flying wire soldering.

[0072] In other embodiments, such as Figure 9 As shown, Figure 6 The third schematic diagram in section A1-A1 shows that the display module 100 includes a main connector 5, a first inter-board connector 4, and an FPC flexible flat cable 8. The first inter-board connector 4 and the main connector 5 are mounted on the back of the main carrier board 11, and the first inter-board connector 4 is electrically connected to the main connector 5 through the main carrier board 11. The FPC flexible flat cable 8 has a first terminal portion and a second terminal portion. The first terminal portion is electrically connected to the first inter-board connector 4, and the LED unit 3 on the secondary carrier board 21 is electrically connected to the second terminal portion, so that the main connector 5 can realize power supply and communication between the main panel 1 and the secondary panel 2 of the display module 100. Eliminating the connector on the back of the secondary panel 2 reduces the number of parts and lowers costs.

[0073] In other embodiments, such as Figure 16 and Figure 17 As shown, the main panel 1 includes multiple sub-panels 12, which are electrically connected to each other. The multiple sub-panels 12 are assembled into the main panel 1.

[0074] Specifically, such as Figure 16 The eighth type of display panel shown has a main panel 1 comprising four sub-panels 12. Both the main panel 1 and the sub-panels 12 are square, and the four sub-panels 12 are the same size and are assembled into a square main panel 1. This allows the corresponding sub-panel 12 to be directly replaced when a certain lamp bead unit 3 on the main panel 1 is damaged, further reducing maintenance costs.

[0075] Each panel 12 has a first inter-panel connector 4 installed on its back. The panel 12 near the side edge of the base 9 has a main connector 5 installed on its back. The first inter-panel connectors 4 on two adjacent panels 12 are electrically connected via FPC flexible flat cable. The main connector 5 is electrically connected to the first inter-panel connector 4 via the panel 12. The first inter-panel connector 4 on one of the panels 12 is electrically connected to the second inter-panel connector 6 on the back of the secondary panel 2 via FPC flexible flat cable. The main connector 5 is used to provide power and communication to each panel 12 and the secondary panel 2.

[0076] In one embodiment, Figure 7 As shown, the LED unit 3 includes LED beads 31 without a built-in driver chip; a driver chip 32 is mounted on the back of the display panel. Understandably, the top of the LED beads 31 is covered with a lampshade (not shown in the figure).

[0077] Of course, in other embodiments, such as Figure 8 As shown, the LED unit 3 may include LED beads 31 with built-in driver chips, and there are no driver chips on the back of the display panel to improve the integration of the LED unit 3.

[0078] In addition, one embodiment of this utility model provides a display module 100, the structure of which is the same as that of the display module 100 in any of the above embodiments, and will not be described again here.

[0079] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
