High-density small-spacing LED display screen

Abstract

The invention discloses a high-density small-spacing LED display screen. The high-density small-spacing LED display screen comprises a frame and a rear cover. The back surface of the frame is movably connected with a rear cover. Mounting holes are formed in the surface of the rear cover. The periphery of the back surface of the rear cover is fixedly connected with a shell. The side, close to the mounting hole, of the shell is movably connected with a pull rod. The end, close to the shell, of the pull rod penetrates through the shell and extends out of the shell. Sliding rails are fixedly connected to the two sides of the inner wall of the shell. The high-density small-spacing LED display screen of the invention belongs to the technical field of LED display screens. According to the high-density small-spacing LED display screen, mounting holes are formed in the surface of the rear cover. The LED display screen is more convenient to install, shorter in installation time, free of tools, higher in installation stability and convenient to disassemble during maintenance. The maintenance efficiency is improved. A fan is fixedly connected to one side of the inner wall of the frame body, so that the LED display screen is better in heat dissipation performance and better in heat dissipation effect. The normal work of the display screen cannot be affected, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a high-density small-pitch LED display screen. Background technique [0002] LED display is a flat-panel display, which is composed of small LED module panels. It is used to display various information such as text, images, video and video signals. The display mode of the diode, a diode made of a compound of gallium and arsenic, phosphorus, nitrogen and indium, can radiate visible light when electrons and holes recombine, so it can be used to make a light-emitting diode as an indicator in circuits and instruments Lights, or composed of text or digital display, gallium arsenide phosphide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, indium gallium nitride diodes emit blue light, the luminous color and luminous efficiency of LEDs are related to the production of LEDs The material and process are related. The...
