[0003] In related technologies, large outdoor LED displays are generally assembled from multiple smaller displays and powered by a single external power supply. During actual assembly, to ensure the reliability of the electrical connection between adjacent smaller displays, mechanical connecting components are typically installed between them. This results in noticeable gaps at the connection points between adjacent smaller displays, severely impacting the user's viewing experience. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0030] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0031] See Figures 1 to 4 This application provides a display screen, which includes: a substrate 100, including a first circuit 110 and a second circuit 120; at least one coil assembly 200, movably disposed on the substrate 100 and connected to the first circuit 110; and at least one light-emitting assembly 300, disposed on the substrate 100 and connected to the second circuit 120, wherein one light-emitting assembly 300 is correspondingly disposed with one coil assembly 200 and is located in the magnetic field generated by the corresponding coil assembly 200 so as to generate current when the coil assembly 200 moves.

[0032] In this embodiment, a regular current is provided to the coil assembly 200 through a first circuit 110 provided on the substrate 100, so that the moving coil assembly 200 can generate a regular magnetic field. By controlling the magnitude of the magnetic field generated by the coil assembly 200, the current in the light-emitting component 300 can be adjusted, thereby adjusting the brightness and intensity of the display screen. Simultaneously, a closed loop is provided to the light-emitting component 300 through a second circuit 120 provided on the substrate 100. Thus, when the coil assembly 200 moves and generates a magnetic field, a current can be formed in the light-emitting component 300 to drive it to emit light, achieving the display effect. Compared to traditional displays that require additional mechanical structures to achieve electrical connection between two adjacent small-sized displays to ensure the reliability of the entire display's electrical connection, the display provided in this embodiment provides current to the light-emitting component 300 through the moving coil assembly 200, resulting in a better user viewing experience; furthermore, it is convenient to disassemble and assemble, and more flexible in its construction.

[0033] Specifically, the display screen is configured as a combination of at least a substrate 100, a coil assembly 200, and a light-emitting component 300. The substrate 100 can be a PCB board with etched circuits, on which a first circuit 110 and a second circuit 120 are arranged at intervals. The first circuit 110 can be used to provide current to the coil assembly 200 so that the moving coil assembly 200 can generate a magnetic field. The second circuit 120 can be used to provide a closed loop to the light-emitting component 300 so that the light-emitting component 300 in the moving magnetic field emits light, thereby achieving the display effect. A clearance groove can be provided on the substrate 100 at the location where the coil assembly 200 is connected. The coil assembly 200 is placed in this clearance groove, so it will not scratch the substrate 100 during movement, thus protecting both the coil assembly 200 and the substrate 100 and extending the service life of the display screen. The two ends of the coil assembly 200 are respectively connected to the positive and negative poles of the first circuit 110 so that it can be connected to an external power source to generate a magnetic field. When multiple coil assemblies 200 are provided, they can be arranged in an array on the substrate and connected in parallel or series to the first circuit 110. Then, they can be driven to move simultaneously using the same driving mechanism to improve the synchronization of the display screen and reduce costs. The light-emitting component 300 can be an LED lamp bead structure with conductors on it. It can generate current when the coil assembly 200 moves to achieve the light-emitting effect. When multiple light-emitting components 300 are provided, they can be arranged in an array on the substrate. One light-emitting component 300 is placed in the magnetic field generated by one coil assembly 200 to achieve synchronous light emission of multiple light-emitting components 300 and synchronous display of the screen. The display screen provided in this example has a simple structure and supplies power to the LED beads through a process of electromagnetism and magnetism. When splicing, the electrical connection requirements at the junction of two adjacent small screens are lower, which can achieve splicing with small gaps or no gaps, thus improving the user's viewing experience.

[0034] In one example, the substrate 100 includes a substrate layer, a first thermally conductive layer, a second thermally conductive layer, a first heat dissipation layer, and a second heat dissipation layer. The first and second thermally conductive layers are respectively disposed on opposite sides of the substrate layer. The first heat dissipation layer is disposed on the side of the first thermally conductive layer away from the substrate layer, and the second heat dissipation layer is disposed on the side of the second thermally conductive layer away from the substrate layer. The first and second heat dissipation layers can be made of thermally conductive carbon fiber material. After prolonged operation, a large amount of heat will accumulate on the substrate layer. This heat can be absorbed and conducted through the first and second thermally conductive layers, and then dissipated through the first and second heat dissipation layers, thereby preventing the substrate layer from overheating during operation and improving the operational safety and reliability of the substrate 100.

[0035] See Figure 1 and Figure 2In one possible implementation, the light-emitting component 300 includes a first conductor 310 and a light-emitting element 320. The first conductor 310 is located in the magnetic field generated by the coil component 200, and the light-emitting element 320 is electrically connected to the first conductor 310 and connected to the second circuit 120.

[0036] In this embodiment, the specific configuration of the light-emitting component 300 is optimized. Specifically, the light-emitting component 300 is configured as a combined component including at least a first conductor 310 and a light-emitting element 320. The first conductor 310 can be a spiral metal wire or a columnar metal block, which can be electrically connected to the light-emitting element 320 by bonding or welding. The light-emitting element 320 can be an LED bead or a light sheet, generally referring to a light-emitting diode, which emits light by releasing energy through the recombination of electrons and holes. The first conductor 310 is located in the magnetic field generated by the coil assembly 200, and can generate current inside it when the coil assembly 200 moves, thereby powering the light-emitting element 320 and realizing the light-emitting effect of the light-emitting element 320, thus realizing the display effect of the display screen. The light-emitting component 300 provided in this example has a compact layout, excellent synergistic effect, and can realize magnetoelectric light emission.

[0037] See Figure 1 and Figure 2 In one possible implementation, the light-emitting component 300 further includes a first shield 330, which is connected to the light-emitting component 320 and surrounds the outer periphery of the first conductor 310.

[0038] In this embodiment, the specific configuration of the light-emitting component 300 is further optimized. Specifically, the light-emitting component 300 is configured as a combination of at least a first conductor 310, a light-emitting element 320, and a first shielding element 330. The first shielding element 330 can be a metal cover or a cylindrical structure, which covers the periphery of the first conductor 310 to shield the electromagnetic field generated when the first conductor 310 is energized, reducing electromagnetic interference to the outside world. At the same time, it can also limit the influence of external electromagnetic fields on the first conductor 310, improving the protection of the first conductor 310. In addition, the first shielding element 330 can also homogenize the electric field, prevent axial discharge of the first conductor 310, and improve operational safety.

[0039] See Figure 1 and Figure 2 In one possible implementation, the light-emitting component 300 further includes a capacitor 340, which is electrically connected to the side of the first conductor 310 away from the light-emitting component 320.

[0040] In this embodiment, the specific configuration of the light-emitting component 300 is further optimized. Specifically, the light-emitting component 300 is configured as a combination of at least a first conductor 310, a light-emitting element 320, and a capacitor 340. The capacitor 340 can be a capacitor used to store electrical energy at a given potential difference for subsequent use. For example, when a high-frequency current is applied to the first circuit 110, a portion of the current in the first circuit 110 is used to power the light-emitting element 320 to achieve the light-emitting effect; another portion of the current can be stored in the capacitor 340 to store energy in the second circuit 120, so that when a low-frequency current is applied to the first circuit 110, it can power the light-emitting element 320 to achieve the light-emitting effect. The light-emitting component 300 provided in this example has strong endurance and low energy consumption.

[0041] See Figure 1 and Figure 3 In one possible implementation, the coil assembly 200 includes a second conductor 210 and a second shield 220. The second conductor 210 is movable and connected to the first circuit 110, and the second shield 220 surrounds the outer periphery of the second conductor 210.

[0042] In this embodiment, the specific configuration of the coil assembly 200 is optimized. Specifically, the coil assembly 200 is configured as a combination of at least a second conductor 210 and a second shield 220. The second conductor 210 can be a spiral metal wire or a columnar metal block, which can be connected to the first circuit 110 by welding. The second shield 220 can be a metal cover or a cylindrical structure, which covers the periphery of the second conductor 210 to shield the electromagnetic field caused by the second conductor 210 when energized, reducing electromagnetic interference to the outside world. At the same time, it can also limit the influence of external electromagnetic fields on the second conductor 210, improving the protection of the second conductor 210. In addition, the second shield 220 can also homogenize the electric field, prevent the second conductor 210 from axially discharging, and improve operational safety. The coil assembly 200 provided in this example has high safety performance and strong reliability.

[0043] See Figure 1 and Figure 4 In one possible implementation, it also includes a control element 400 and a drive assembly 500, the drive assembly 500 being disposed on the substrate 100, and the control element 400 being configured to control the drive assembly 500 to drive the coil assembly 200 to reciprocate.

[0044] In this embodiment, the specific configuration of the display screen is further optimized. Specifically, the display screen is configured as a combination of at least a substrate 100, a coil assembly 200, a light-emitting component 300, a control component 400, and a driving component 500. The control component 400 can be a chip mounted on the substrate 100 or remote control software on a computer, used to cooperate with the driving component 500 to achieve intelligent driving of the driving component 500, thereby improving the display consistency and display effect of the display screen. The driving component 500 can be a micro motor mounted on the substrate 100, with its output end connected to the coil assembly 200. It can drive the coil assembly 200 to reciprocate along a specified motion trajectory. When the first circuit 110 is energized, the coil assembly 200 can be driven to move, generating a magnetic field around it. The light-emitting component 300 is in this magnetic field. When the coil assembly 200 moves, its relative position to the light-emitting component 300 changes, and the magnetic flux between them changes, thus placing the light-emitting component 300 in a changing magnetic field. The light-emitting component 300 generates a current inside it, which causes the light-emitting component 300 to emit light. The display screen provided in this example can adjust the magnetic flux around the light-emitting component 300 by controlling the movement of the coil component 200 driven by the driving component 500. At the same time, the rate of change of the magnetic flux around the light-emitting component 300 can be changed by the speed of movement of the coil component 200, thereby adjusting the brightness and intensity of the light-emitting component 300, and thus adjusting the display screen image for better display effect.

[0045] See Figure 4 In one possible implementation, the drive assembly 500 includes a drive harness 510, a connector 520, and a drive unit (not shown in the figure). One end of the drive harness 510 is connected to the connector 520 and connected to the first circuit 110, and the other end is connected to the coil assembly 200. The output end of the drive unit is connected to the connector 520.

[0046] In this embodiment, the specific configuration of the drive component 500 is optimized. Specifically, the drive component 500 is configured as a combination of at least a drive harness 510, a connector 520, and a drive element. The drive element can be a micro motor, which can be connected to the non-circuit area of ​​the substrate 100 by fasteners such as screws / bolts. The connector 520 can be a connecting plate, which is connected to the output end of the drive element and located in the non-circuit area of ​​the substrate 100 to reduce interference with the components on the first circuit 110 and the second circuit 120. The drive harness 510 can be a metal wire with a certain rigidity and hardness, and is disposed between the connector 520 and the coil assembly 200. When the drive element drives the connector 520 to move back and forth, the drive harness 510 moves with the connector 520 and drives the coil assembly 200 to move synchronously, thereby realizing intelligent driving of the coil assembly 200.

[0048] In one possible implementation, the first circuit 110 includes a first switching element 111, a magnetic signal sensing element 112, and a power supply 113. The first switching element 111 is connected to the coil assembly 200, and the other end of the first switching element 111 is connected to the magnetic signal sensing element 112. The other end of the magnetic signal sensing element 112 is connected to the power supply 113, and the other end of the power supply 113 is connected to the coil assembly 200.

[0049] In this embodiment, the specific configuration of the first circuit 110 is optimized. Specifically, the first circuit 110 is configured as a combination of at least a first switching element 111, a magnetic signal sensing element 112, and a power supply 113. The first switching element 111 can be a circuit switch used to control the on / off state of the first circuit 110; the magnetic signal sensing element 112 can be a sensor used to obtain the magnitude of the magnetic flux on the coil assembly 200; and the power supply 113 can be an external battery. The first circuit 110 provided in this example is powered by an external power source to provide a small current to the moving coil assembly 200, so that it can generate a magnetic field around its periphery when moving. This places the light-emitting component 300 in the moving magnetic field and generates current inside it, thus achieving light emission. This is energy-saving, environmentally friendly, and provides a high level of user experience.

[0050] See Figure 1 and Figure 5 In one possible implementation, the second circuit 120 includes a second switching element 121, a grounding element 122, and a signal output element 123. The two ends of the second switching element 121 are respectively connected to the two ends of the light-emitting component 300. One end of the grounding element 122 is connected between the second switching element 121 and the light-emitting component 300, and the other end is grounded. The signal output element 123 is electrically connected to the second switching element 121.

[0051] In this embodiment, the specific configuration of the second circuit 120 is optimized. Specifically, the second circuit 120 is configured as a combination of at least a second switching element 121, a grounding element 122, and a signal output element 123. The second switching element 121 can be a circuit switch used to control the on / off state of the second circuit 120; the grounding element 122 can be a grounding device used to connect to the earth to reduce leakage hazards to the display screen and the user, effectively prevent electric shock accidents, and improve personal safety; the signal output element 123 can be a display screen used to output display signals from the light-emitting component 300.
