LED display screen capable of assembling and disassembling display module from front surface

Abstract

The invention discloses an LED display screen structure capable of assembling and disassembling a display module from the front surface, and an assembling and disassembling method. The method comprises the following steps that the whole screen consists of a plurality of LED display modules, a bottom supporting framework, an assembling and disassembling electric controller and an electromagnetic suction plate; the single LED display module is fixed in the corresponding unit grid of the bottom supporting framework through a pin plugging mechanism controlled by an electromagnet; pin insertion hole seats are connected to a U-shaped sliding sheet capable of sliding along a supporting rim, and the whole LED display screen is flatly seamless by adjusting and fixing the proper positions of all the pin insertion hole seats; the assembling and disassembling electric controller can control the pin insertion mechanisms controlled by all the electromagnets of the corresponding LED display modules to be opened and closed through an inner processor, so that local decomposition or combination of the LED display screen is realized; a magnetic metal plate is arranged at the back part of each LED display module, and a high-power electromagnet is arranged in an electromagnetic suction plate; after electrification, the electromagnetic suction plates are arranged on the front surfaces of the decomposed LED display modules to realize assembling and disassembling under the electromagnetic suction force on the metal plates.

Description

Technical field [0001] The invention relates to the structure and disassembly method of an LED display screen, in particular to a combination and splicing of multiple LED display modules, which are fixed by an electromagnet control pin mechanism and pulled out by electromagnetic force. The single LED can be disassembled and assembled from the front The structure and disassembly method of the LED display of the display module. Background technique [0002] In recent years, as one of the important modern information release tools, LED display screens have been widely used in many fields such as finance, transportation, advertising, sports, entertainment, and education. Various LED display screen structures and installation technologies have also been continuously proposed and developed. However, most of the current LED displays still adopt a modular structure, especially large-scale full-color LED displays; this is mainly due to the reduction of manufacturing costs, more convenien...

AI Technical Summary

Problems solved by technology

[0006] The present invention is aimed at LED display screens, especially large LED display screens that are installed on the wall or on the ground and are composed of multiple LED display modules. When a single display module has a bad pixel and needs to be repaired, it is inconvenient to disassemble and assemble. , designed a structural method and disassembly method of an LED display that uses an electromagnet to control the latch mechanism to be fixed, and can be disassembled and pulled out through electromagnetic force attraction. A single display module can be disassembled from the front.
