It is mainly analyzed from two aspects:

（1） LED electronic display system composition:

The system consists of special computer equipment, display screen, video input port and system software.

Computers and special equipment: computers and special equipment directly determine the functions of the system, and different types can be selected according to different requirements of users for the system.

Display screen: the control circuit of the display screen receives the display signal from the computer, drives the LED to emit light to generate a picture, and outputs sound by adding power amplifiers and speakers.

Video input port: provide video input port, signal source can be video recorder, DVD player, camera, etc., support NTSC, PAL, S_ Video and other systems.

System software: provide special software for LED playback, powerpoint or ES98 video playback software.

（2） LED electronic display system functions

The system has the following functions:

With the computer as the processing control center, the electronic screen corresponds to a certain area of the computer display (VGA) window point by point, the display content is synchronized in real time, the screen mapping position is adjustable, and the size of the display screen can be conveniently selected at will.

The display lattice adopts ultra-high brightness LED (red and green primary colors), 256 gray levels, 65536 color change combinations, rich and realistic colors, and supports VGA 24 bit true color display mode.

Equipped with graphic information and 3D animation playing software, it can play high-quality graphic information and 3D animation. There are more than ten ways to play the information displayed by the software, such as covering, closing, curtain opening, color alternation, zooming in and out.

Special program editing and playing software can be used to edit, add, delete and modify text, graphics, images and other information through keyboard, mouse, scanner and other different input means. The layout is stored in the control host or the server hard disk, and the program playing sequence and time are integrated and alternately played, and can be overlapped
