Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an automatic calibration structure of a display screen unit. Background Art

[0002] With the development of display technology, large-scale display screens have been widely used in various fields such as commercial displays, public information dissemination, and command and control centers. To achieve a larger display area and higher resolution, multiple small display cabinets are usually spliced ​​together to form a large screen. Different layouts (such as 2x2, 3x3, etc.) and different arrangements (such as horizontal or vertical splicing) are often required according to the needs.

[0003] The current traditional splicing technology relies on manually placing the corresponding display screen cabinets in the appropriate position, distributing the signal source image output to each display screen cabinet, and then using auxiliary equipment to capture the image of the spliced ​​large screen. The software algorithm then analyzes the marker points in the image to determine the position of each display unit. This is costly and the steps are cumbersome. Utility Model Content

[0004] In order to solve the problems in the above background technology, the utility model provides an automatic calibration structure of a display screen unit.

[0005] The solution adopted by the utility model to solve its technical problems is: an automatic calibration structure of a display screen unit, including a display unit and a calibration mechanism for positioning multiple display units when spliced ​​together, the display unit including a plurality of light board modules arranged in a rectangular shape and a control box for controlling each light board module, the calibration mechanism including an infrared emitting sensor arranged at a corner end of the light board module and located on one side of the display unit, and an infrared receiving sensor arranged at a diagonal end of the infrared emitting sensor and located on the other side of the display unit for receiving signals emitted by infrared emitting sensors at corresponding positions on adjacent display units.

[0006] By adopting the above technical solution, by setting infrared transmitting sensors and infrared receiving sensors at the corner ends of each light board module, the transmission characteristics of infrared signals are used to perform accurate position detection and automatic calibration.

[0007] Furthermore, welding areas for welding and mounting infrared emitting sensors and infrared receiving sensors are provided around the display unit.

[0008] By adopting the above technical solution, a welding area is provided at each corner end, so as to weld the infrared emitting sensor and the infrared receiving sensor on the light board module close to the four sides of the overall display unit according to specific use.

[0009] Furthermore, the control box includes a shell and a control board arranged in the shell, the light board module is provided with a first connection port on the side facing the control board, and the control board is provided with a second connection port on the side facing each light board module, the number of which is equal to the number of the light board modules. The first connection port and the second connection port are plugged together to establish an electrical connection between the light board module and the control box.

[0010] By adopting the above technical solution, the first connection port and the second connection port are plugged together to establish an electrical connection, thereby solving the problem of messy wiring at the rear side of the display unit module.

[0011] Furthermore, each of the light board modules is provided with two first connection ports, and the two first connection ports are arranged symmetrically with respect to a center line of the light board module.

[0012] By adopting the above technical solution, the positions of the infrared receiving sensor and the infrared transmitting sensor of the light board module can be adjusted.

[0013] Furthermore, the back of the shell has a plurality of heat dissipation slots, and each of the heat dissipation slots passes through the shell and is arranged in parallel in batches.

[0014] By adopting the above technical solution, the heat generated by the control board and other internal components is quickly discharged to the external environment to keep the internal temperature of the control box within a safe operating range, preventing performance degradation or hardware damage caused by overheating.

[0015] Furthermore, each of the control boxes has an input interface and an output interface. The input interface of any display unit is used to connect to a signal source, and the input interface of a subsequent display unit is connected to the output interface of the previous display unit.

[0016] By adopting the above technical solution, users can flexibly expand the number of screens as needed without the need for complicated wiring or additional signal distribution equipment.

[0017] In summary, the present invention offers the following beneficial effects: By integrating infrared emitting and receiving sensors into the corners of the light panel module, it creates an infrared emitting or receiving area at the center of each display unit's four edges. This utilizes the transmission characteristics of infrared signals for precise position detection and automatic calibration, significantly improving the installation efficiency of tiled display screens. Furthermore, the plug-in connection between the light panel module and the control box eliminates external cable connections, resolving the issue of cluttered wiring on the rear side of the display unit module.

[0027] like Figures 1 to 4 As shown, an automatic calibration structure of a display screen unit, wherein this embodiment includes a display unit 1 and a calibration mechanism 4 for positioning multiple display units 1 when spliced, and the display unit 1 includes a plurality of light board modules 2 arranged in a rectangular shape and a control box 3 for controlling each light board module 2, and the calibration mechanism 4 includes an infrared emitting sensor 41 provided at a corner end of the light board module 2 and located on one side of the display unit 1, and an infrared receiving sensor 42 provided at a diagonal end of the infrared emitting sensor 41 and located on the other side of the display unit 1 for receiving signals emitted by the infrared emitting sensor 41 at a corresponding position on an adjacent display unit 1.

[0028] The display unit 1 of this embodiment is a display screen housing. The accompanying drawings illustrate the effect of two display units 1 working together, each capable of independently displaying content. It comprises a plurality of light board modules 2 within a housing frame, plus a control box 3. The light board modules 2 are rectangularly arranged LED light boards, each controlled by a corresponding control box 3. Furthermore, a calibration mechanism 4 is provided within each display unit 1. This calibration mechanism 4 comprises an infrared emitting sensor 41 and an infrared receiving sensor 42. These sensors are mounted to the corners of the light board modules 2 located near the center of each of the four sides of each display unit 1. Specifically, if an infrared emitting sensor 41 is mounted to a corner of the light board module 2 near the center of the top and right side of the display unit 1, an infrared receiving sensor 42 is mounted to a corner of the light board module 2 near the center of the bottom and left side of the display unit 1. This creates an infrared signal emitting area on the top and right side of the display unit 1, while an infrared signal receiving area is formed on the bottom and left side of the display unit 1. When two display units 1 are placed close together, the infrared transmitter 41 on one display unit 1 sends a signal to the corresponding infrared receiver 42 on the adjacent display unit 1. The control system calculates the relative positions of each display unit 1 based on the transmitted and received infrared signals. When multiple display units 1 are joined together, each unit 1 can be automatically positioned to display the desired content, forming a large screen. This significantly improves the efficiency of joining display units 1. Furthermore, by directly integrating the infrared sensor into the light board module 2, the need for additional connecting cables is reduced, making the entire display system more compact and simple.

[0029] like Figure 1 As shown, in the four light board modules 2 inside the display unit 1 in this embodiment (preferably four light board modules 2 in this embodiment), a calibration mechanism 4 is installed in the two diagonal light board modules 2 respectively. Specifically, an infrared emitting sensor 41 is arranged at the lower left corner of the light board module 2 located at the upper left position and the lower right position, thereby forming an infrared emitting area near the center position on the lower side and left side of the display unit 1; an infrared receiving sensor 42 is arranged at the upper right corner, thereby forming an infrared emitting area near the center position on the upper side and right side of the display unit 1.

[0030] like Figure 1 As shown, in this embodiment, the display unit 1 is provided with welding areas 5 on all sides for welding and mounting the infrared emitting sensor 41 and the infrared receiving sensor 42. By providing the welding areas 5 on all sides of the display unit 1, the infrared emitting sensor 41 and the infrared receiving sensor 42 can be welded to the light board module 2 near the four edges of the entire display unit 1 according to specific use.

[0031] like Figure 2 and Figure 3 As shown, in this embodiment, the control box 3 includes a housing 31 and a control board 32 disposed within the housing 31. The light board modules 2 are provided with first connection ports 21 on the side facing the control board 32. The control board 32 is provided with a number of second connection ports 321, equal to the number of light board modules 2, on the side facing each light board module 2. The first connection ports 21 and the second connection ports 321 are plugged together to establish an electrical connection between the light board modules 2 and the control box 3. By plugging the first connection ports 21 within each light board module 2 into the corresponding second connection ports 321 on the control board 32, an electrical connection is established between each light board module 2 and the control board 32, eliminating the need for external cable connections and resolving the issue of cluttered wiring on the rear side of the display unit 1 module.

[0032] like Figure 1 and Figure 2 As shown, each light board module 2 in this embodiment is provided with two first connection ports 21, which are arranged symmetrically with respect to the center line of the light board module 2. By plugging different first connection ports 21 into the second connection port 321 of the control board 32, the positions of the infrared receiving sensor 42 and the infrared transmitting sensor 41 of the light board module 2 can be adjusted.

[0033] like Figure 3 As shown, the back of the housing 31 in this embodiment has multiple heat dissipation slots 311. Each heat dissipation slot 311 extends through the housing 31 and is arranged in parallel. The heat dissipation slots 311 allow air circulation, helping to quickly dissipate heat generated by the control board 32 and other internal components to the external environment. This helps maintain the internal temperature of the control box 3 within a safe operating range, preventing performance degradation or hardware damage caused by overheating.

[0034] like Figure 2 and Figure 3As shown, each control box 3 in this embodiment has an input interface 33 and an output interface 34. The input interface 33 of any display unit 1 is used to connect to a signal source, and the input interface 33 of a subsequent display unit 1 is connected to the output interface 34 of the previous display unit 1. That is, a display unit 1 is selected as the first level, and its input interface 33 is connected to the output end of the signal source to receive the picture signal, while the input interface 33 of the adjacent display unit 1 is connected to the output interface 34 of the first-level display unit 1. Subsequent display units 1 are connected in series in sequence, so that the signal can be transmitted from the first display unit 1 to the last display unit 1. This constitutes a cascade connection relationship, allowing the user to flexibly expand the number of screens as needed without the need for complex wiring or additional signal distribution equipment, and helps maintain image consistency and synchronization.

[0035] In summary, the beneficial effects of this embodiment are as follows: By integrating infrared emitting sensors 41 and infrared receiving sensors 42 into the corners of the light board module 2, this embodiment can form an infrared emitting area or an infrared receiving area at the center of each display unit 1 on all four sides. The transmission characteristics of infrared signals are utilized for precise position detection and automatic calibration. This allows each display unit 1 to display content independently when separated, and to display the desired content together to form a large screen when spliced ​​together, significantly improving the installation efficiency of the spliced ​​display screen. Furthermore, the plug-in connection between the light board module 2 and the control box 3 eliminates the need for external cable connections, solving the problem of cluttered wiring on the rear side of the display unit 1 module.

[0036] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
