LED display screen

Abstract

The invention discloses an LED (Light-emitting Diode) display screen which comprises a box body and a display module assembled and fixed with the box body, wherein a first adsorption piece is arranged on an assembling surface where the box body is assembled with the display module; a second adsorption piece adaptive to the first adsorption piece is arranged in a position corresponding to the display module; and an electromagnetic switch is arranged on the box body, and used for controlling the magnetism of the first adsorption piece. According to the LED display screen, the magnetism of the first adsorption piece is controlled by the electromagnetic switch; when the display module is dismounted, the first adsorption piece is controlled to lose magnetic force and allow the display module to be separated from the box body, and the display module is taken out from the box body; when the display module is mounted, the first adsorption piece is controlled to recover the magnetic force, and the display module is absorbed by the first adsorption piece to be mounted and fixed on the box body, so that purposes of dismounting and mounting the display module quickly are achieved; the production efficiency of the LED display screen is improved; the LED display screen is convenient to maintain; and the dismounting cost, the mounting cost and the maintenance cost are lowered.

Description

technical field [0001] The invention relates to the field of LED display manufacturing, in particular to an LED display. Background technique [0002] As the production technology of LED display becomes more and more mature and its application becomes more and more extensive, various industries, especially the display leasing industry, pay more and more attention to the quick installation and disassembly of display modules of LED display. [0003] Due to space and cost constraints, many existing LED displays do not have a maintenance channel. During use, for occasions that require front maintenance, the display module needs to be disassembled from the LED display box. After the maintenance, the display module and the cabinet can be assembled and fixed after the maintenance is completed.

Problems solved by technology

[0003] Due to space and cost constraints, many existing LED displays do not have a maintenance channel. During use, for occasions that require front maintenance, the display module needs to be disassembled from the LED display box. Maintenance can only be carried out after the maintenance is completed. After the maintenance is completed, the display module and the box body will be assembled and fixed.

However, because the existing display modules are generally assembled and fixed by screws, the production takes a lot of time, so the production efficiency is not high, and it is inconvenient to disassemble the display module, and it is difficult to perform front maintenance, resulting in increased labor costs for disassembly and maintenance.
