Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an LED display screen. Background Art

[0002] In the field of large-scale LED display screens, LED display screens are assembled in the form of assembling. First, several concepts are introduced to help you understand the technical solutions more clearly.

[0003] Unit cabinet: consists of cabinet, display module, power supply and system.

[0004] Screen body: Several unit cabinets are assembled to form the screen body.

[0005] Assembled structure: The whole composed of many installation structural parts such as steel structure, hanging beam, ground beam, etc. outside the screen body.

[0006] LED display screen; the screen body and the assembly structure constitute the LED display screen.

[0007] At present, the unit cabinet design of most LED display screens uses the cabinet to assemble the display module, power supply, and system card into a complete machine. In addition to serving as a carrier for assembling display modules, power supply, system cards, etc., the cabinet also has positioning and locking structures between the cabinets.

[0008] Therefore, when using unit cabinets to assemble LED display screens, the assembly between cabinets and the assembly between cabinets and assembly structures complement each other. In the process of assembling LED display screens, the splicing of cabinets and cabinets realizes the needs of display screen shape. In addition to meeting the installation strength and stability of the screen installation, the assembly structure also needs to be processed and assembled in accordance with the shape requirements.

[0009] That is, the assembly of the cabinet is the core of the display screen shape, and the assembly structure is auxiliary. In terms of overall strength, the assembly structure is the main body, and the screen body assembled from the cabinet is also very important.

[0010] For example, if you need to assemble an LED curved display screen, first weld the assembly structure according to the application and shape, then connect and fix the cabinet according to the shape and assembly structure, and the cabinets also need to be connected and fixed.

[0011] After assembling several unit boxes to form a screen, connect the power lines, signal lines between the boxes, as well as the power input and signal input of the screen. It can be seen that when assembling the screen, in addition to installing the assembly structure, the screen also needs to be assembled.

[0012] The assembly structure needs good strength to support the entire screen, and the cabinet also needs good strength. Therefore, for the above assembly method, the cabinet design needs more strength redundancy. For example, when installing on a stand, the bottom row of cabinets needs to be able to withstand the extrusion force of the entire screen weight; when hoisting, the top row of cabinets needs to be able to withstand the tension of the entire screen weight. Therefore, the cabinet design needs to calculate the strength according to the limit value used. For most cabinets, the limit strength is redundant.

[0013] In assembly, not only the assembly structure needs to be made and installed, but also the connection structure between the boxes and between the boxes and the assembly structure needs to be designed. In this way, the assembly structure design of the entire large-screen system is relatively complicated, and the actual application operation is also complicated. Utility Model Content
