[0039] See also Figure 1 , Figure 1 A schematic diagram of a display device according to an embodiment of the utility model is shown.

[0040] like Figure 1 As shown, the device comprises:

[0041] A plurality of display components 10, each of which is provided with a magnetic power interface 101 and a magnetic data interface 102, each of which is spliced ​​into a target shape through the magnetic power interface 101 and the magnetic data interface 102, the magnetic power interface 101 is used to transmit power, and the magnetic data interface 102 is used to transmit data signals, wherein the display component 10 further includes:

[0042] A battery assembly 110, wherein the input end of the battery assembly 110 is connected to the magnetic power interface 101,

[0043] A power switching component 120, wherein a first input interface of the power switching component 120 is connected to the magnetic power interface 101, and a second input interface of the power switching component 120 is connected to the output end of the battery component 110,

[0044] The voltage conversion component 130 is connected to the output end of the power switching component 120.

[0045] The display module 140 includes at least one display panel 1410 and a display driving unit 1420. The data input end of the display module 140 is connected to the magnetic data interface 102. The power input end of the display module 140 is connected to the output end of the voltage conversion component 130.

[0046] The display component 10 includes at least one surface, each display panel 1410 is arranged on the corresponding surface of the display component 10 , and the battery and components, the power switching component 120 , and the display driving component are arranged inside the display component 10 .

[0047] Each display component 10 of the embodiment of the utility model is provided with a magnetic power interface 101 and a magnetic data interface 102. Each display component 10 is spliced ​​into a required target shape through the magnetic power interface 101 and the magnetic data interface 102. It has great flexibility in installation location and shape, and the modular form is convenient for repair and maintenance, with low maintenance costs. In addition, the display component 10 is provided with a battery component 110, which has a flexible power supply method.

[0048] The embodiment of the utility model does not limit the specific shape of the display component 10. The shape of the display component 10 can be various, and those skilled in the art can set it according to actual conditions and needs. For example, in one possible implementation, the display component 10 is any one of a cube, a cuboid, a sphere, a cylinder, a cone, etc. For a display device, it can include several types of display components 10, for example, it can include at least one cubic display component 10, at least one spherical display component 10, and at least one cylindrical display component 10. Each display component 10 is spliced ​​to form a target shape through the magnetic power interface 101 and the magnetic data interface 102. Of course, the embodiment of the utility model does not limit the specific form of the target shape, and those skilled in the art can set it according to actual conditions and needs.

[0049] The embodiment of the utility model modularizes the display assembly 10 in the form of a cube, and lightens the installation structure, computer console, wiring transmission signal and other equipment, and integrates them in the cube to become a movable "building block". The stacking of these building blocks can also achieve a large-area display screen, and can be placed in a special form according to the characteristics of the site to form a special shape, which is much more novel than the general square or rectangular display area. If the equipment is damaged, only a single display assembly 10 needs to be replaced. For example, a spare cube can be reserved for the user, and the user can take it and replace the damaged module by himself.

[0050] For example, the embodiment of the utility model can stack the display components 10 to form any shape, so the display device is not limited to a certain wall or a certain structure. And the size of a single cube can be customized. Large size: it can be placed in a consumer goods store, such as a window position, to attract customers to shop in the store. At the same time, it forms a modeling device to attract customers to check in and take photos for dissemination. It can also be placed in the square or atrium of commercial real estate, and can also be combined with art and culture in art galleries and museums. Small size: it can be a palm-sized furniture ornament, placed on a desktop or in a display cabinet. This device is not only a display device, but also a "symbol". How to express its cultural value, commercial value, and artistic value can be decided by the user, and this is not limited by the embodiment of the utility model.

[0051] It should be noted that the components of the embodiments of the present invention can all be implemented by hardware circuits.

[0052] The embodiment of the utility model does not limit the number and location of the magnetic power interface 101 and the magnetic data interface 102, and those skilled in the art can set them according to actual conditions and needs.

[0053] See also Figure 2a , Figure 2b , Figure 2c , Figure 2d , Figure 2e , Figure 2a , Figure 2b , Figure 2c , Figure 2d , Figure 2e A schematic diagram, a cross-sectional view, a side-sectional view, a top view, and a bottom view of a display assembly 10 according to an embodiment of the present utility model are respectively shown.

[0054] In a possible implementation, Figure 2a , Figure 2b , Figure 2c , Figure 2d , Figure 2e As shown, the display component 10 is a regular hexahedron (also called a cube, a cube), and the magnetic power interface 101 and the magnetic data interface 102 are provided on the first and second opposite surfaces of the display component 10, and the remaining surfaces of the display component 10 are provided with a display panel 1410.

[0055] Exemplarily, a foldable handle may be centrally installed at a central position of one side (such as the top surface) of the display assembly 10 to facilitate safe and convenient transfer of the display assembly 10 .

[0056] The present invention does not limit the number of display panels 1410 provided in the display component. For example, Figure 2a As shown, the display panel 1410 can be set on all four sides, or 1 to 4 sides can be selected as needed to set the display panel 1410. Of course, the display panel 1410 can also be set on the first side and the second side where the magnetic suction interface is set.

[0057] The embodiments of the utility model do not limit the type of display panel, and those skilled in the art can set it according to actual conditions and needs. For example, in a possible implementation, the display panel 1410 may include any one of a liquid crystal display panel, an organic light emitting diode display panel, a quantum dot light emitting diode display panel, a mini light emitting diode display panel and a micro light emitting diode display panel.

[0058] It is worth mentioning that conventional display screens can only display square and rectangular images. If the naked-eye 3D effect is to be achieved, two screens need to be spliced ​​at a 90-degree right angle, and the corresponding back frame needs to be modified. It is a separate customization, which is expensive and cannot be restored. Figure 2aThe display assembly 10 shown is a cube, naturally with a 90-degree splicing screen, which can display both naked-eye 3D videos and conventional TVC flat videos. Those skilled in the art can set it according to actual conditions and needs. In addition, this display device can be stacked and combined, with various shapes. It can be a conventional rectangle, a staggered ladder, or a special device shape, such as a pixelated imitation of a brand logo, a pixelated imitation of the morphology of plants and animals, and a pixelated imitation of objects. Then, according to different shapes (target shapes), the video content will push the corresponding video for playback according to the artificial intelligence algorithm. For example, multiple cubic modules can be arranged into the shape of a shoe, and multiple color images of the corresponding shoe model and videos of product features can be pushed, and the algorithm can be used to calculate the appropriate display content for playback on the display device.

[0059] The embodiment of the utility model does not limit the implementation method of the battery assembly 110. Those skilled in the art can set it according to actual conditions and needs. For example, the battery assembly 110 may include multiple battery cells, and the battery cells may be lithium-ion batteries, lithium polymer batteries, sodium-ion batteries, solid-state batteries or any other type of cyclically chargeable and dischargeable batteries.

[0060] In a possible implementation, the voltage conversion component 130 may include a plurality of voltage conversion units, each of which is used to convert a received voltage into a target voltage.

[0061] The embodiments of the present invention do not limit the implementation method and number of the voltage conversion units. Those skilled in the art can set them according to actual conditions and needs. For example, the voltage conversion unit may include a direct current to direct current conversion unit (DC / DC), and the number and parameters of the voltage conversion units may be set according to the size of the power supply required. For example, assuming that the display driving unit 1420 requires 12V and 5V power supply, two voltage conversion units may be set to output 12V and 5V voltages respectively; if 4 display panels 1410 are included, and each display panel 1410 requires 5V power supply, the 4 voltage conversion units may be set to output 5V voltage to power each display panel 1410 respectively.

[0062] In a possible implementation, the device may further include:

[0063] A charging base is provided with a magnetic power interface 101 for magnetically connecting with the magnetic power interface 101 of the display component 10 and providing power to the display component 10 .

[0064] Exemplarily, each display component 10 can be directly spliced ​​to form a display device and powered by the battery component 110 therein to achieve short-term image display or video playback. Of course, multiple display components 10 can also be assembled and placed in a charging base, and each display component 10 can be powered by the charging base to achieve long-term display.

[0065] In a possible implementation manner, the charging base is further provided with:

[0066] The power conversion module includes an AC-DC conversion component and a DC-DC conversion component. The power conversion module converts the received AC power into a DC voltage required by the display component 10 through the AC-DC conversion component and the DC-DC conversion component.

[0067] Exemplarily, the power conversion module can be connected to alternating current (AC) and convert the AC into direct current (DC) for power supply.

[0068] For example, the power conversion module can be connected to 220V AC, and the AC-DC conversion component and the DC-DC conversion component are used to convert the 220V AC into 24V DC to power the entire display device. The 24V power first flows from the switch to the magnetic power interface 101 of the charging base. For example, the charging base, the bottom surface of the display component 10, and the top surface interface of the display component 10 are arranged at the midpoint position of the four sides, so that the display component 10 can be connected no matter which side it faces; the charging base uses the female head of the magnetic power interface 101, the bottom surface of the display component 10 uses the male head, and the top surface of the display component 10 uses the female head, so that they can be stacked on each other. When the display component 10 is placed on the charging base, the 24V DC flows into the display component 10 through the magnetic interface and is divided into two paths, one for charging the battery component 110 (such as a lithium battery), and the other is connected to the main power interface on the power switching component 120, and the output of the lithium battery is connected to the secondary power interface on the power switching component 120. The output interface of the power switching component 120 provides power to the entire display component 10. Its output is divided into five paths. One path flows to the 24V to 12V module. The 24V power is converted to 12V power by this module to power the mini host in the display driver component. The other four paths flow to the 24V to 5V module. The 24V power is converted to 5V power by this module to provide power for the four LED screens of the display component 10 and the sending card and receiving card in the display driver component.

[0069] Exemplarily, when the display component 10 is placed on the base, the 24V power supply is connected to the main power interface on the power switching component 120 through the magnetic interface. At this time, the electrical equipment connected to the output end of the power switching component 120 uses the main power, and the 24V power supply also charges the lithium battery; when the display component 10 is detached from the charging base, the main power input of the power switching component 120 disappears and switches to the secondary power provided by the lithium battery to provide power for the subsequent electrical equipment.

[0070] The embodiment of the utility model does not limit the specific implementation method of the power switching component 120. Those skilled in the art can set it according to actual conditions and needs. For example, the power switching component 120 may include a multiplexer MUX, or be composed of multiple switches.

[0071] In a possible implementation, the charging base is further provided with: a voltage detection module, which is used to detect the voltage of the battery assembly 110 in the display assembly 10 through the magnetic power interface 101, and if the voltage in the battery assembly 110 reaches a voltage threshold, the charging path to the battery assembly 110 is cut off.

[0072] The embodiment of the utility model does not limit the specific implementation method of the voltage detection module, and those skilled in the art can adopt relevant technologies to implement it according to actual conditions and needs.

[0073] Exemplarily, the charging base may also include a charging control module for implementing charging mode control of the battery assembly 110. For example, the charging control module may be used to control constant current charging, constant voltage charging, trickle charging, etc. of the battery assembly 110 as needed. In addition, a temperature acquisition unit may be provided to detect the temperature of the battery assembly 110. When the temperature is higher than a preset temperature, charging is suspended until the temperature of the battery assembly 110 drops to a preset temperature. In order to perform temperature control, a heat dissipation assembly may also be provided to achieve heat dissipation of the battery assembly 110.

[0074] In a possible implementation, the charging base further includes a control component, and the control component is used to:

[0075] The display data of each display component 10 is distributed according to the target shape formed by splicing each display component 10 .

[0076] The embodiments of the utility model do not limit the specific implementation of the control component, and those skilled in the art may set it according to actual conditions and needs. For example, the control component includes but is not limited to a separate processor, or discrete components, or a combination of a processor and discrete components. The processor may include a controller having an execution instruction function in an electronic device, and the processor may be implemented in any appropriate manner, for example, by one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors or other electronic components. Inside the processor, the executable instructions may be executed by hardware circuits such as logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers.

[0077] Of course, a storage module may also be provided in the charging base and / or the display assembly 10 to store display data. When the display device is formed by splicing a plurality of display assemblies 10, each display assembly 10 may realize the mutual transmission of data and the induction of the display state through the magnetic data interface 102, thereby adaptively adjusting the display content of each display panel 1410 of each display assembly 10; if each display assembly 10 is spliced ​​and arranged on the charging base, the control assembly in the charging base may realize the distribution control of the display content of each display panel 1410 of each display assembly 10. Those skilled in the art may realize these specific control methods by using relevant technologies, and the embodiments of the utility model are not limited thereto.

[0078] In one example, the storage module may include a computer-readable storage medium, which may be a tangible device that can hold and store instructions used by the instruction execution device. The computer-readable storage medium may be, for example, but not limited to, an electrical storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the above. More specific examples of computer-readable storage media (a non-exhaustive list) include: a portable computer disk, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), a static random access memory (SRAM), a programmable read-only memory (PROM), a portable compact disk read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanical encoding device, such as a punch card or a raised structure in a groove on which instructions are stored, and any suitable combination of the above. The computer-readable storage medium used herein is not to be interpreted as a transient signal itself, such as a radio wave or other freely propagating electromagnetic wave, an electromagnetic wave propagating through a waveguide or other transmission medium (e.g., a light pulse through a fiber optic cable), or an electrical signal transmitted through a wire.

[0079] In a possible implementation, the display driving unit 1420 may also be used for:

[0080] The received display data is divided into display data, and the divided display data is sent to each display panel 1410 for display.

[0081] See also Figure 3 , Figure 3 A schematic diagram of a display assembly 10 according to an embodiment of the present utility model is shown.

[0082] For example, Figure 3 As shown, the display module may include display panels 1 to 4, and the display driving unit 1420 may include a mini host 14203, a sending card 14202, and a receiving card 14201. The mini host 14203 receives data through the magnetic data interface 102, and the mini host 14203 can process the received data and transmit the processed data (such as video data) to the sending card 14202. The sending card 14202 can segment the received display data and send the segmented display data to the receiving cards 14201 corresponding to each display panel 1410, and each display panel 1410 then displays the corresponding video data.

[0083] The embodiment of the utility model does not limit the specific implementation method of the mini host 14203, the sending card 14202, and the receiving card 14201, and does not limit the specific method of the mini host 14203 to implement data processing. Those skilled in the art can adopt relevant technologies to implement according to actual conditions and needs. Of course, the display driving unit 1420 can also be an integrated hardware circuit without dividing the mini host 14203, the sending card 14202, and the receiving card 14201.

[0084] Exemplarily, the overall video picture synchronization of the display component 10, the hot update of the material server, and the hardware communication part can be processed by the mini host 14203. The mini host 14203 transmits data through the USB to TTL module in the contact data magnetic port. Of course, it can also be summarized on the central control host to identify the placement position of each unit, and then analyze the different position information through the central control system to parse out the picture that each unit should play, so as to play the specified effect.

[0085] In a possible implementation manner, the charging base further includes:

[0086] A camera component is used to capture an image of a target object.

[0087] The embodiments of the present invention do not limit the specific implementation of the camera assembly, and those skilled in the art may configure it according to actual conditions and needs. For example, the camera assembly may include a CCD camera, a CMOS camera or other cameras.

[0088] Exemplarily, the target object may be, for example, a user in front of the camera assembly.

[0089] In a possible implementation, the control component may be used to:

[0090] generating a text description including features of the target object based on the image of the target object;

[0091] Generate target video data according to the text description;

[0092] The target video data is distributed to each display component 10 for display.

[0093] The embodiment of the utility model does not limit the specific implementation method of generating a text description including the features of the target object according to the image of the target object, and does not limit the specific implementation method of generating target video data according to the text description; those skilled in the art can adopt relevant technologies according to actual conditions and needs. For example, the generation of text description and the generation of video data can be realized by a corresponding neural network model.

[0094] Exemplarily, a camera can be used to collect information such as the user's clothing and facial expressions at the front end, and the data can be transmitted via UDP or a server to an artificial intelligence model (neural network model). After receiving the data, the neural network model performs keyword screening to create a descriptive story, and based on the story, the image content is secondary output and returned in an mp4 format video, which is presented on the screen of each display component 10.

[0095] Through the above configuration, the advantages of the display device of the embodiment of the utility model are:

[0096] 1. Variable visual output: After the product is put into use, the picture content changes according to the shape, and there is no need to make it separately. The visual content and marketing methods are effectively matched.

[0097] 2. Replace user-specified content remotely to improve service levels.

[0098] See also Figure 4 , Figure 4 A schematic diagram of a process of displaying by a display device according to an embodiment of the utility model is shown.

[0099] For example, Figure 4 As shown, after the splicing of each display component 10 is completed, the embodiment of the utility model can first initialize the display device, including the initialization of the serial port, the screen, etc., and then determine whether the preset display data is updated. If there is an update, the material is downloaded from the server and updated to the local (display component 10 or charging base). If there is no update, the default picture is played. Taking two display components 10 as an example, the magnetic data interfaces 102 (including serial ports A and B) of the two display components 10 are connected, and the serial port A of the display component 10 is used to monitor external information, and the serial port B of the display component 10 is used to send information regularly. If serial port A receives information, the unique number of the display component 10 is added to the end of the information received by serial port A and sent through serial port B. According to the central control processing information, the video picture to be played is specified, and it is determined whether serial port A has data reception. If all information reception is completed, the process is terminated, and the unique number of the display component 10 is sent through serial port B, and the default picture continues to be played.
