Description

Technical Field

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

[0002] In the current indoor LED display market, there exists a "module bulk market" model. This means that users purchase various components of the display screen themselves: display modules, open power supplies, receiver cards, electronic cables, etc., and then install them on mounting brackets by themselves for use.

[0003] The above solution offers a significant cost advantage by eliminating the cabinet structure found in traditional LED displays. However, it also has a prominent drawback: it demands a high level of expertise from the user. Ordinary users are highly susceptible to system instability, uneven brightness, or even equipment burnout due to incorrect selection or improper installation, severely impacting display quality and lifespan. Utility Model Content

[0004] One objective of this invention is to solve the technical problem of high professional threshold when users assemble displays according to their own needs, and to provide a display that is easy for ordinary users to assemble.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A display screen, comprising: frame; The display module is provided in multiple ways. The display module is detachably disposed on one side of the frame. Each display module has a first socket with a U-shaped outline on each side edge. The display module includes a first connector, which corresponds to the first socket. A power signal box is detachably mounted on the side of the frame opposite to the display module; The data connection cable is provided in multiple configurations. One end of each data connection cable is provided with a first connector. The first connector includes a first plug and a first locking structure. The first plug can pass through the first plug hole and be adapted to be inserted into the first socket, thereby forming an electrical connection between the data connection cable and the display module. The first locking structure can be locked and fixed to the display module through the first plug hole. The other end of the data connection cable can be electrically connected to the power signal box, thereby forming an electrical connection between the power signal box and each of the display modules.

[0007] In some embodiments of this application, the frame includes multiple installation areas, each of which is provided with a display unit; the display surfaces of the display units in the multiple installation areas can be spliced ​​together.

[0008] In some embodiments of this application, the first locking structure includes a first elastic portion and a first pressing portion connected to the first elastic portion. The first elastic portion is elastic, and when an external force is applied to the first pressing portion, the first elastic portion can undergo elastic deformation so that the first pressing portion can be relatively close to the first connector. When the external force is released, the first elastic portion returns to its original deformation so that the first pressing portion can elastically abut against the inner sidewall of the display module relatively away from the first connector.

[0009] In some embodiments of this application, the first connector has a first interface, which is a reversible pluggable interface.

[0010] In some embodiments of this application, the power signal box is provided with a plurality of second sockets, and the edge contour of at least one side of the second socket is convex; the power signal box includes a second connector, which corresponds to the second socket; The data connection cable has a second connector at one end away from the first connector. The second connector includes a second connector and a second locking structure. The second connector can pass through the second socket and be adapted to be inserted into the second socket, so that the data connection cable and the power signal box are electrically connected, and the second locking structure can be locked and fixed to the power signal box through the second socket.

[0011] In some embodiments of this application, the second locking structure includes a second elastic portion and a second pressing portion connected to the second elastic portion. The second elastic portion is elastic, and when an external force is applied to the second pressing portion, the second elastic portion can undergo elastic deformation so that the second pressing portion can be relatively close to the second connector. When the external force is released, the second elastic portion returns to its original deformation so that the second pressing portion can elastically abut against the inner wall of the power signal box relatively away from the second connector.

[0012] In some embodiments of this application, a plurality of second sockets are provided on both opposite sides of the power signal box; the plurality of second sockets on the same side of the power signal box are interconnected.

[0013] In some embodiments of this application, the display screen includes a network cable, the power signal box includes a receiving signal interface and a transmitting signal interface, and the transmitting signal interface in one display unit can be connected to the receiving signal interface in another display unit via the network cable.

[0014] In some embodiments of this application, the display screen includes a magnetic suction element, one side surface of the display module is a display surface, and the magnetic suction element is disposed on the side of the display module opposite to the display surface, so that the display module is magnetically attached to the frame by the magnetic suction element.

[0015] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: The display screen of this utility model includes a frame, a power signal box, multiple display modules, and multiple data connection cables. Each display module has a first socket. One end of each data connection cable has a first connector. The first connector can be inserted into a first socket in the display module through the first socket. The other end of the data connection cable can be electrically connected to the power signal box, thus establishing an electrical connection between the display modules and the power signal box, enabling the power signal box to control each display module.

[0016] It is understandable that the display module and power signal box in this application are modularly designed. Users can choose the number of display modules according to their needs and connect the display modules and power signal box using data connection cables to assemble the main body of the display screen. The operation is simple, and even ordinary users with low professional skills can assemble the display screen.

[0017] Furthermore, the first jack, whose upper edge contour is convex, works in conjunction with the data connection cable to ensure a secure connection between the display module and the data connection cable. Attached Figure Description

[0032] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0033] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] Please see Figure 1and Figure 2 This application provides a display screen 100, including a frame 1, a display module 2, a power signal box 3, and a data connection cable 4. The display module 2 and the power signal box 3 are respectively disposed on opposite sides of the frame 1. The power signal box 3 and the display module 2 are connected by the data connection cable 4 to realize signal transmission and realize the control of the display module 2 by the power signal box 3.

[0036] One side surface of display module 2 is display surface 231. Multiple display modules 2 are provided. Multiple display modules 2 can be spliced ​​together.

[0037] See Figure 3 and Figure 4 In some embodiments, a first socket 21 is provided on the side of the display module 2 facing away from the display surface 231. The display module 2 includes a first connector 22. The first connector 22 corresponds to the first socket 21 so that the data connection cable 4 can be inserted into the first connector 22 through the first socket 21.

[0038] Furthermore, the data connection cable 4 includes a first connector 41. The first connector 41 is provided with a first tap 411. See also... Figure 5 The first socket 21 includes a main body area 211. The first connector 22 corresponds to the main body area 211, so that the first connector 411 can pass through the main body area 211 and be inserted into the first connector 22 to realize the electrical connection between the data connection line 4 and the display module 2.

[0039] The first connector 22 has a first interface, which can be a USB interface, a DP interface, an HDMI interface, etc. Preferably, the first interface is a reversible pluggable interface. Correspondingly, the first connector 411 in the data cable 4 is also a reversible pluggable connector. For example, the first interface is a Type-C interface, and the first connector 411 is a Type-C interface. The reversible pluggable design of the first interface and the first connector 411 allows the user to quickly insert the first connector 411 into the first interface of the first connector 22 without worrying about the orientation.

[0040] See Figure 5 and Figure 6The edges of the first socket 21 on both sides are convex. For ease of description, the areas in the first socket 21 with convex edges on both sides are defined as the first connection area 212 and the second connection area 213. The first connector 41 in the data cable 4 includes a first locking structure 412. The first locking structure 412 can be locked and fixed to the display module 2 by any one or at least one of the first connection area 212 or the second connection area 213, making the connection between the data cable 4 and the display module 2 more secure, effectively preventing the connection between the data cable 4 and the display module 2 from loosening due to external force, thus affecting signal transmission.

[0041] The first locking structure 412 in the display module 2 and the data connection line 4 will be further described below.

[0042] Please see Figure 3 and Figure 5 In some embodiments, the display module 2 includes a lamp panel 23, a bottom shell 24, and a rear cover 25, with the lamp panel 23 and the rear cover 25 respectively disposed on opposite sides of the bottom shell 24. The surface of the lamp panel 23 facing away from the rear cover 25 is the display surface 231. A first insertion hole 21 is disposed on the rear cover 25. The rear cover 25 includes a cover body 251 and a limiting portion 252 disposed on the side of the cover body 251 near the bottom shell 24. The edge contours of the limiting portion 252 on opposite sides are U-shaped. In other words, the setting of the limiting portion 252 forms a first connecting area 212 and a second connecting area 213, both with U-shaped edge contours. The first connecting area 212 and the second connecting area 213 are respectively connected to the main body area 211. The edge contours of the first connecting area 212 and the second connecting area 213 are arranged mirror-symmetrically along the center line of the main body area 211.

[0043] See Figure 6 The first locking structure 412 includes a first elastic portion 4121 and a first pressing portion 4122 connected to the first elastic portion 4121. The first connector 41 includes a body 413. The first connector 411 protrudes from one side of the body 413. One end of the first elastic portion 4121 is disposed on the body 413, and the other end extends beyond the surface of the body 413, with its extension direction consistent with the direction of the body 413 toward the first connector 411. The first pressing portion 4122 is disposed on the end of the first elastic portion 4121 away from the body 413. The first elastic portion 4121 is elastic, and when an external force is applied to the first pressing portion 4122, the first elastic portion 4121 can undergo elastic deformation, so that the first pressing portion 4122 can be relatively close to the first connector 411; when the external force is released, the first elastic portion 4121 returns to its deformation, so that the first pressing portion 4122 is relatively away from the first connector 411 and can elastically abut against the inner wall of the rear cover 25.

[0044] Furthermore, the first elastic portion 4121 includes a straight section 4121a and an arc-shaped section 4121b. One end of the straight section 4121a is disposed on the main body 413. The straight section 4121a can be disposed on the same side of the main body 413 where the joint is located, or it can be disposed on the adjacent side of the main body 413 where the joint is located.

[0045] In some embodiments, the straight section 4121a may include an arc-shaped transition surface 4121c. The transition surface 4121c is located on the back side of the junction between the straight section 4121a and the main body 413. It can evenly distribute stress and avoid stress concentration that could lead to cracks, thereby improving the connection stability and durability between the straight section 4121a and the main body 413. In addition, the provision of the transition surface 4121c makes the end of the straight section 4121a approximately arched, which has good bending resistance, thereby enhancing the structural strength of the straight section 4121a and reducing the possibility of deformation or vibration of the straight section 4121a.

[0046] A straight section 4121a is spaced apart from the first connector 411. The straight section 4121a extends in the same direction as the housing towards the first connector 411, and extends beyond the end face of the housing. An arc-shaped section 4121b is disposed at the end of the straight section 4121a that extends beyond the surface of the housing. The cross-section of the arc-shaped section 4121b is approximately inverted C-shaped, with its two ends on the same side by a fold in the middle. The arc-shaped section 4121b is connected to the crimping part, and the first pressing part 4122 is located on the side of the straight section 4121a opposite to the first connector 411.

[0047] The first pressing part 4122 includes a crimping section 4122a and a pressing section 4122b. The crimping section 4122a is connected to the arc-shaped section 4121b, and the pressing section 4122b is connected to the end of the crimping section 4122a opposite to the arc-shaped section 4121b. The width of the crimping section 4122a can be the same as the width of the arc-shaped section 4121b to ensure a stable connection between the body and the arc-shaped section 4121b. The width of the pressing section 4122b is smaller than the width of the crimping section 4122a.

[0048] For ease of description, the side wall of the limiting part 252 near the main body area 211 is defined as the pressing wall 2521, and the side wall of the limiting part 252 near the bottom shell 24 is defined as the abutting wall 2522.

[0049] Combination Figure 7 and Figure 8It can be seen that while the first connector 411 is inserted into the first connector 22, the first locking structure 412 is engaged with the rear cover 25. Specifically, the process can be as follows: while the first connector 411 is inserted into the first connector 22 through the main body area 211, the straight section 4121a passes through the first connecting area 212 and through the rear cover 25. The pressing wall 2521 of the limiting part 252 presses against the pressing section 4122a in the first pressing part 4122, causing the arc-shaped section 4121b in the first elastic part 4121 to elastically deform, and the pressing section 4122a moves towards the straight section 4121a. As the depth of the first connector 41 inserted into the display module 2 gradually increases... The first connector 411 is inserted into the first connector 22 to form an electrical connection. At this time, the crimping section 4122a is completely housed inside the display module 2 and is separated from the contact with the crimping wall 2521. Under the action of the rebound of the first elastic part 4121, the first pressing part 4122 moves in a direction away from the straight section 4121a. At this time, the farthest part of the crimping section 4122a away from the straight section 4121a moves away from the main body area 211 and exceeds the crimping wall 2521. The blocking wall 2522 in the limiting part 252 prevents the crimping section 4122a from separating from the inside of the display module 2, thereby realizing the first locking structure 412 being locked on the back cover 25.

[0050] It is understandable that the process of unlocking the connection between the first locking structure 412 and the back cover 25 can be as follows: the user presses the pressing section 4122b with his / her hand, causing the first pressing part 4122 to move towards the straight section 4121a, and the first elastic part 4121 to deform until the projection of the pressing section 4122a does not coincide with the blocking wall 2522. Then, the first plug 41 is pulled away from the display module 2, thereby releasing the connection between the first locking structure 412 and the back cover 25 and disconnecting the electrical connection between the first connector 411 and the first socket 22.

[0051] The first connection area 212 and the second connection area 213 in the display module 2 allow the first locking structure 412 to be snapped and fixed to the back cover 25 via the second connection area 213. The specific operation process is roughly the same as described above and will not be repeated here.

[0052] It should be noted that the display module 2 in this application has no other interfaces besides the first connector 22. Power and signal transmission can be achieved through the first connector 22. The fact that the display module 2 has no other interfaces besides the first connector 22 effectively simplifies the wiring connection between the power signal box 3 and the display module 2, so that only one data connection cable 4 is needed between the power signal box 3 and the display module 2. This makes operation convenient and effectively reduces the complexity of assembling the display screen 100.

[0053] See Figure 2 and Figure 9The data connection cable 4 includes a cable body 42, one end of which is provided with a first connector 41, and the other end of which is provided with a second connector 43. The second connector 43 includes a second connector 431 (not shown in the figure). The power signal box 3 has a second socket 31. The power signal box 3 also includes a second connector 32, which corresponds to the second connector 43, so that the second connector 431 can pass through the second socket 31 and be inserted into the second connector 32.

[0054] The second connector 431 can be of the same type as the first connector 411; for example, both the second connector 431 and the first connector 411 can be Type-C connectors. Alternatively, both the second connector 431 and the first connector 411 can be DP interfaces. In other embodiments, the second connector 431 can be of a different type than the first connector 411; for example, the second connector 431 can be an HDMI interface, and the first connector 411 can be a Type-C connector. The specific type can be set according to actual needs.

[0055] Preferably, the second connector 431 is a reversible pluggable connector. Correspondingly, the second interface in the second connector 32 on the power signal box 3 is a reversible pluggable interface. For example, the second connector 431 is a Type-C connector, and the second interface is a Type-C interface. The reversible pluggable design of the second connector 431 and the second interface allows the second connector 431 to be inserted into the second interface in either direction, which facilitates a quick connection between the data connection cable 4 and the power signal box 3.

[0056] See Figure 10 In some embodiments, the second connector 43 may include a second locking structure 432, which can be snapped and fixed to the power signal box 3 through the second socket 31 to enhance the connection stability between the second connector 43 and the power signal box 3.

[0057] Please see Figure 10 and Figure 11 The power signal box 3 includes a box body 33. A second socket 31 is disposed on the box body 33. The second socket 31 includes a first assembly area 311 and a second assembly area 312. The first assembly area 311 corresponds to the second connector 32, so that the second connector 431 can be inserted into the second connector 32 through the first assembly area 311 to form an electrical connection. The second assembly area 312 is disposed on one side of the first assembly area 311 and is connected to the first assembly area 311. The edge contour of the second assembly area 312 is U-shaped, and the second locking structure 432 can be snapped and fixed to the box body 33 through the second assembly area 312.

[0058] The second locking structure 432 includes a second elastic portion 4321 and a second pressing portion 4322. The second elastic portion 4321 is disposed on the insertion body 433 and extends beyond the surface of the insertion body 433. The second pressing portion 4322 is disposed on the end of the second elastic portion 4321 that extends beyond the insertion body 433. The second elastic portion 4321 is elastic; when an external force is applied to the second pressing portion 4322, the second elastic portion 4321 can undergo elastic deformation, allowing the second pressing portion 4322 to approach the insertion body 433 and extend into the interior of the power signal box 3 through the second assembly area 312. After the second elastic portion 4321 recovers its deformation, the second pressing portion 4322 moves away from the insertion body 433 and elastically abuts against the inner wall of the box 33, thus locking the second locking structure 432 onto the box 33.

[0059] It should be noted that the specific structure of the second elastic part 4321 can be roughly the same as the structure of the first elastic part 4121, and the specific structure of the second pressing part 4322 can be roughly the same as the structure of the first pressing part 4122, which will not be described in detail here.

[0060] See Figure 11 The second socket 31 has a convex edge profile on at least one side. This means that a second assembly area 312 can be provided on both opposite sides of the first assembly area 311. The second locking structure 432 can be snapped and fixed to the housing 33 via either of the second assembly areas 312. The edge profiles of the two second assembly areas 312 on opposite sides of the first assembly area 311 are arranged mirror-symmetrically along the center line of the first assembly area 311. It is understood that this arrangement is particularly suitable for designs where the second interface in the second connector 32 is a reversible pluggable interface.

[0061] See Figure 9 The box 33 has multiple second sockets 31 on one side, meaning it has multiple second connectors 32. Therefore, multiple data cables 4 can be used to connect multiple display modules 2. A power signal box 3 contains a control module 34, and multiple second connectors 32 are respectively mounted on the control module 34. After connecting multiple display modules 2 to a power signal box 3, control of the multiple display modules 2 can be achieved, which helps ensure the synchronization and consistency of the content of multiple display modules 2 connected to the same power signal box 3. Compared to the traditional configuration of one control module 34 per display module 2, this not only effectively saves the user the cost of purchasing the power signal box 3 but also simplifies the complexity of assembling the display screen 100.

[0062] The box 33 may have multiple second sockets 31 on both sides. That is, the power signal box 3 has multiple second connectors 32 on each side. Compared with the main control board having an interface on only one side, this configuration expands the number of second connectors 32, allowing more display modules 2 to be connected via data connection cables 4. It also simplifies the physical wiring when multiple data connection cables 4 are connected to the power signal box 3, resulting in neater wiring.

[0063] See Figure 11 In some embodiments, the multiple second sockets 31 on the same side of the housing 33 can be interconnected to facilitate the processing of the housing 33 and to speed up the production efficiency of the power signal box 3.

[0064] It should be noted that the number of display modules 2 connected to the power signal box 3 can be flexibly set according to the user's own needs. For example, the number of display modules 2 used can be less than or equal to the number of second connectors 32 on the power signal box 3.

[0065] In some embodiments, the display screen 100 includes at least one display unit. Each display unit includes a plurality of data connection lines 4, a plurality of display modules 2, and a power signal box 3. The ratio of the number of power signal box 3, data connection lines 4, and display modules 2 is 1:N:N. N can be a natural number between 2 and 10.

[0066] See Figure 1 and Figure 2 For example, a display unit includes a power signal box 3, eight data connection lines 4, and eight display modules 2. In other embodiments, a display unit may include a power signal box 3, six data connection lines 4, and six display modules 2, etc.

[0067] The display screen 100 includes a frame 1, and the frame 1 has at least one display unit. The following description takes an example where the frame 1 has one display unit.

[0068] See Figure 12 The frame 1 includes an outer frame 11 and at least one vertical beam 12. The vertical beam 12 is located inside the outer frame 11, and its two ends are respectively connected to the inner walls of opposite sides of the outer frame 11. See also... Figure 4 The display screen 100 includes a magnetic component 5, which is disposed on the side of the display module 2 away from the display surface 231, so that the display module 2 is magnetically attached to the frame 1 by the magnetic component 5.

[0069] In some embodiments, a vertical beam 12 may be provided, and the vertical beam 12 may be arranged at the center line of the outer frame 11. One side of the display module 2 is magnetically fixed to the outer frame 11 by a magnetic 5, and the other side is magnetically fixed to the vertical beam 12 by a magnetic 5. It can be understood that the display surface 231 in the display module 2 extends beyond the surface of the outer frame 11 at this time.

[0070] Or see Figure 1 and Figure 12 Multiple display modules 2 in a display unit are installed inside the outer frame 11. Multiple vertical beams 12 may be provided. For example, three vertical beams 12 are provided, in which case the opposite sides of the display modules 2 can be magnetically fixed to two adjacent vertical beams 12 by magnetic attachments 5.

[0071] In some embodiments, the frame 1 may include a crossbeam 13, with its opposite ends connected to the inner walls of opposite sides of the outer frame 11. The crossbeam 13 is arranged at an angle to the vertical beam 12, exemplarily, the angle can be 90 degrees. The arrangement of the crossbeam 13 enhances the structural strength of the frame 1, helps the frame 1 maintain its shape integrity, and prevents the frame 1 from deforming.

[0072] It should be noted that the arrangement of mounting the display unit inside the outer frame 11 ensures that at least one edge of the display module 2 within the display unit is in contact with the inner wall of the outer frame 11. In this configuration, the outer frame 11 forms a protective layer for the multiple interconnected display modules 2 within the display unit, effectively preventing the side edges of the display modules 2 from being exposed to the outside. Furthermore, the outer frame 11 also provides some support for the display modules 2, enhancing the stability of the display modules 2 arranged on the frame 1.

[0073] See Figure 2 and Figure 12 The power signal box 3 in the display unit is mounted on the vertical beam 12 in the frame 1. (See also...) Figure 2 , Figure 11 and Figure 12 In some embodiments, the power signal box 3 includes a mounting portion 35, which protrudes from the box body 33. The mounting portion 35 may be integrally formed with the box body 33. The mounting portion 35 has a mounting hole 351, and the vertical beam 12 has an assembly hole 121. Fasteners are used to pass through the mounting hole 351 and the assembly hole 121, thereby mounting the power signal box 3 onto the vertical beam 12. The fasteners may be bolts, screws, etc.

[0074] See Figure 13 and Figure 14 The display screen 100 may include multiple display units. These multiple display units are connected and interlocked. The following explanation uses an example where multiple display units are mounted on frame 1.

[0075] The frame 1 includes multiple adjacent mounting areas 14, each mounting area 14 housing a display unit. The display surfaces of the display units in the multiple mounting areas 14 can be connected. Specifically, the frame 1 includes an outer frame 11 and multiple vertical beams 12. The multiple vertical beams 12 are spaced apart along the length direction of the display module 2. The opposite sides of the display module 2 along the length direction can be magnetically fixed to two adjacent vertical beams 12 by magnetic attachments 5.

[0076] Each display unit has a first connector 22 on both sides of the power signal box 3. Therefore, to fully utilize the power signal box 3, the number of display modules 2 in a display unit can be equal to the number of first connectors 22, allowing multiple display modules 2 in a display unit to be connected to form a two-column multi-row array. Two display modules 2 in each row of the display unit can be magnetically fixed to the same vertical beam 12 using magnetic attachments 5. Therefore, at least three vertical beams 12 are required for one mounting area 14 in the frame 1. The power signal box 3 can be fixed to the middle vertical beam 12 among the three vertical beams 12.

[0077] It is understandable that the length of the installation area 14 is consistent with the length formed by splicing together each column of display modules 2 in the display unit. Multiple display units can be arranged in an array, and the dimensions of the outer frame 11, the length of the vertical beams 12, and their quantity can be adaptively configured based on the number of rows and columns formed by connecting multiple display units. For example... Figure 13 As shown, there are 12 display units, which can be arranged in three rows and four columns. Therefore, there are at least 9 vertical beams 12 to magnetically fix the display modules 2, which consist of eight columns of four display units. The length of one vertical beam 12 is sufficient to magnetically fix three interconnected display units.

[0078] See Figure 11 The power signal box 3 includes two network interfaces: a receiving signal interface 36 and a transmitting signal interface 37. The receiving signal interface 36 and the transmitting signal interface 37 are electrically connected to the control module 34. The display screen 100 includes a network cable (not shown). Signals from external signal sources, such as control hosts like computers, can be transmitted via the network cable to the receiving signal interface 36 on the power signal box 3 of one of the display units. Then, the transmitting signal interface 37 in that display unit is connected to the receiving signal interface 36 in another display unit via another network cable, thus enabling signal transmission between adjacent display units. In this way, the power signal boxes 3 in the remaining adjacent display units can be connected sequentially via network cables, thereby enabling unified control of each power signal box 3 in the display screen 100 by external signal sources.

[0079] The aforementioned receiving signal interface 36 and transmitting signal interface 37 further simplify the assembly process of the display screen 100. Users only need to use a network cable to connect the power signal boxes 3 in the two adjacent display modules 2 in sequence.

[0080] See you later Figure 11 The power signal box 3 includes a power interface 38, which is used to connect an external power supply line so that the external power supply can power the display module 2 through the power signal box 3.

[0081] It should be noted that the power signal box 3 provided in this application has no other interfaces besides the second connector 32, the receiving signal interface 36, the transmitting signal interface 37, and the power interface 38. The number of interfaces is small, which effectively reduces the complexity of assembling the display screen 100.

[0082] When the display screen 100 includes multiple display units, such as two display units, a T-shaped power cable including a main line and two branches can be used. The main line is connected to an external power supply, and the two branches are respectively connected to the power interface 38 of the power signal box 3 in the two display units. This can reduce the physical wiring harness and improve the convenience of the user in assembling the display screen.

[0083] When there are more than two display units, one T-shaped power cable can be used for each pair of adjacent display units. Furthermore, when there are multiple T-shaped power cables, the main lines of adjacent T-shaped power cables can also be connected to further reduce the number of wires.

[0084] Alternatively, when there are more than two display units, a power cable with multiple branches can be used, with each branch corresponding to a power signal box 3 in one display unit.

[0085] Understandably, the synergistic effect of the display screen and the power cord with multiple branches in this application not only facilitates user operation but also allows for neat distribution of the wiring harness, thereby improving safety and preventing short circuits, overheating, or wear caused by tangled or pressed wires. It also facilitates fault detection and troubleshooting, reducing accidents caused by messy wiring. In summary, this application modularizes the frame 1, display module 2, data connection cable 4, and power signal box 3, making assembly convenient, reducing installation complexity, and improving user-friendliness. Even ordinary users with limited professional skills can assemble the display screen 100. The power signal box 3, display module 2, and data connection cable 4 can form a display unit in a 1:N:N ratio, and the power signal box 3 and display module 2 only require the data connection cable 4 for connection, simplifying the wiring. Adjacent display units can be connected using only a network cable. It should be noted that this application only exposes the necessary interfaces of the display module 2 and the power signal box 3, while the remaining electronic components are located inside the display module 2 and the power signal box 3. This not only reduces the assembly complexity but also improves the safety of assembling the display screen 100, effectively avoiding the safety hazards caused by the exposed electronic components when users assemble the screen themselves using the components.
