Problems solved by technology

At present, the magnetic suction type front maintenance small-pitch LED display at home and abroad is absorbed by a single module, and then multiple modules are directly adsorbed on the box body or installation components through the magnetic steel base. In order to meet the actual assembly and disassembly needs, its magnetic attraction Smaller, after being assembled into a large LED screen, the small offset and mutual extrusion of the magnetic suction modules will cause the large screen to be repeatedly disassembled and assembled during maintenanc

Embodiment 1

[0016] The structure of this embodiment is as Figure 1-Figure 4 As shown, the multi-layer magnetic suction front maintenance small-pitch LED display screen includes an area array driver board 2-1 containing light-emitting diodes, and the size of the light-emitting diodes 2-8 is less than 2.5mmX2.5mmX2.0mm, and the light-emitting diodes are arranged and mounted. Constitute a pixel matrix with M rows and N columns, where M and N are both positive integers. The pads 2-2 with fixed intervals are arranged around the area array drive plate 2-1, and the area array drive plate 2-1 is fixedly connected with the first mounting plate 2-4 of the center fixed iron plate 2-3 to form a module 2. 2 The external dimensions are less than 700mmX700mm. Module 2 is tri-primary, dual-primary or single-primary. Module 2 is a single board, double boards or at least three boards. The circuit board of the module is a single-layer board, a double-layer board or at least a three-layer board. The pla...

Embodiment 2

[0019] Such as Figure 5 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1, the difference is that this embodiment is a three-layer magnetic structure, that is, a mounting plate 3 is magnetically attracted between the module and the second mounting plate, and the installation The board 3 is connected with the module and the second mounting board through a connector containing a magnetic core.

Abstract

The invention relates to a small-spacing LED (light-emitting diode) display screen, in particular to a multilayer magnetic type front-maintenance small-spacing LED display screen, belonging to the technical field of LED equipment. The display screen disclosed by the invention structurally comprises an area array driver board containing LEDs; the periphery of the area array driver board is provided with cushion blocks at fixed intervals; the area array driver board is fixedly connected with a first installation plate of a center fixing iron plate to form a module; the module is combined with a second installation plate by means of a magnetic force to form an outer layer magnetic structure; the second installation plate is combined with a box or installation member by means of a magnetic force to form an inner layer magnetic structure; the magnetic force of the outer layer magnetic structure is less than that of the inner layer magnetic structure; the box or installation member adsorbs a module component composed of at least two modules by means of a magnetic force. The display screen disclosed by the invention has the advantages that the problem of tiny drift and extruding of a magnetic module with a small magnetic force after the magnetic module is installed is solved, and the problem that the planeness and module gap cannot be adjusted caused by the fact that the module is fixed on a box or installation member is solved; and the display screen is convenient to assemble and disassemble.

Description

technical field [0001] The invention relates to a small-pitch LED display screen, in particular to a multi-layer magnetic suction type front maintenance small-pitch LED display screen, which belongs to the technical field of LED equipment. Background technique [0002] LED display screens have been widely used due to energy saving and environmental protection. In particular, the small-pitch display with a dot pitch of less than 3mm has an increasing market demand due to its advantages such as bright colors, high resolution, seamless splicing and super mute. At present, the magnetic suction type front maintenance small-pitch LED display at home and abroad is absorbed by a single module, and then multiple modules are directly adsorbed on the box body or installation components through the magnetic steel base. In order to meet the actual assembly and disassembly needs, its magnetic attraction Smaller, after being assembled into a large LED screen, the small offset and mutual e...
