Problems solved by technology

[0002] Various LED products, especially LED displays, are composed of several LED cabinets or modules connected to each other regularly. The existing LED module design is relatively fixed and can only be disassembled as a whole, and most of them cannot be disassembled from the front. There are few layers of disassembly and assembly, which is very inconvenient for maintenance

Abstract

The invention discloses an LED display screen, which comprises a plurality of LED modules in matrix arrangement and sequential cascade connection. Each LED module comprises an eupholic layer, an emitting layer, a mounting layer and a heat dissipation layer; the mounting layer is provided with a plurality of mounting positions and mounting grooves; each mounting groove is provided with a plurality of sets of open-ended spring plates; the mounting layer is also provided with a plurality of sets of positioning holes and positioning rods, which are adapted in shape, the positioning rods are used for positioning and fixing a first LED module where the mounting layer is to the corresponding position of a second LED module, and the positioning holes are used for positioning and fixing the first LED module where the mounting layer is to the corresponding position of a third LED module; the heat dissipation layer is fixed on one side of the mounting layer; the emitting layer is provided with a plurality of emitting layer mounting holes and a plurality of LED lamps in matrix arrangement and fixed on the other side of the mounting layer through the emitting layer mounting holes; the eupholic layer is fixedly mounted on the emitting layer through screws; the eupholic layer and the emitting layer are in sealed arrangement; gratings are arranged between adjacent LED lamps; and the LED modules are positioned and fixed with the positioning rods through the positioning holes.

Description

technical field [0001] The present invention relates to LED displays, in particular to an LED display screen formed by regularly connecting LED boxes or modules. Background technique [0002] Various LED products, especially LED displays, are composed of several LED cabinets or modules connected to each other regularly. The existing LED module design is relatively fixed and can only be disassembled as a whole, and most of them cannot be disassembled from the front. There are few levels of disassembly and assembly, which is very inconvenient for maintenance. [0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an easily disassembled LED display screen, which can realize LED display. [0005] The technical solution of the present invention is as follows: an LED display screen, which includes several LED modules arranged in a matrix and seq...
