The working principle of led display
(1) System composition
This system is composed of computer special equipment, display screen, video input port and system software.
Computer and special equipment: Computer and special equipment directly determine the function of the system, and different types can be selected according to the different requirements of users on 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 produce the picture, and outputs sound by adding power amplifiers and speakers.
Video input port: Provide a video input port. The signal source can be a video recorder, a DVD player, a camera, etc., and it supports multiple formats such as NTSC, PAL, and S_Video.
System software: Provide special software for LED playback, powerpoint or ES98 video playback software.
(2) System function
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 easily and freely selected.
The display dot matrix adopts ultra-high brightness LED light-emitting tubes (red and green dual primary colors), 256 levels of gray, 65536 color combinations, rich and vivid colors, and supports VGA 24-bit true color display mode.
Equipped with graphic information and 3D animation playback software, it can play high-quality graphic information and 3D animation. The playback software can display information in more than ten forms, such as covering, closing, opening the curtain, alternating colors, and zooming in and out.
Using special program editing and playing software, you can edit, add, delete and modify text, graphics, images and other information through different input means such as keyboard, mouse, scanner. The arrangement is stored in the hard disk of the control host or the server, and the sequence and time of the program playing can be integrated and alternately played, and they can be superimposed on each other.
It can receive video signals such as video recorders and DVD players.
Introduction and classification of LED electronic display system
In recent years, the LED display market has developed rapidly, and it has been widely used in banks, post and telecommunications, taxation, airports, stations, securities markets and other trading markets, hospitals, electricity, customs, stadiums and other occasions where announcements and publicity are required. .
LED is the abbreviation of Light Emitting Diode. The LED display is a display device composed of light-emitting diodes. It adopts low-voltage scanning drive, which has the following advantages: 1, low power consumption, 2, long service life, 3, low cost, 4, high brightness, 5, large viewing angle, 6, long visual distance, 7, and many specifications and varieties .
LED display product series:
A, monochrome, color bar display, B, computer-controlled digital display, C, monochrome graphic display, D, three-color (red, green, yellow) graphic display, E, dot matrix and digital Mixed display screen (securities screen), F, dual primary color (red, green) multimedia video synchronization display, G, three primary color (red, green, blue) multimedia video synchronization display
LED display classification:
According to the display color, it is divided into: single red, single green, red and green dual primary colors, red, green and blue three colors
According to the function of use, it is divided into: graphic display, multimedia video display, market information display, bar display
According to the use environment, it is divided into: indoor display, outdoor display, semi-outdoor display
According to the diameter of the luminous spot, it is divided into: φ3.0, φ3.7, φ4.8, φ5.0, φ8.0, ph8, ph10, ph16, ph20, etc.
Among the basic luminous point non-market LED displays, indoor LED displays can be divided into Φ3mm, Φ3.75mm, Φ5mm, Φ8mm, and Φ10mm according to the LED single point diameter used; outdoor LED displays are based on the pixels used The diameter can be divided into Φ16mm, Φ19mm, Φ22mm and Φ26mm LED display screens. The market information LED display can be divided into 2.0cm (0.8inch), 2.5cm (1.0inch), 3.0cm (1.2inch), 4.6cmm (1.8inch), 5.8cm (2.3inch), 7.6 according to the size of the digital tube used. cm (3inch) and other LED displays.
Display color: LED display screen is divided into single-color LED display (including pseudo-color LED display), dual-color LED display and full-color (three-color) LED display according to the display color. According to the gray scale, it can be divided into 16, 32, 64, 128, 256 gray scale LED display screens and so on.
Display performance: LED display screens are divided into text LED display screen, graphic LED display screen, computer video LED display screen, TV video LED display screen and market LED display screen according to display performance. Market LED displays generally include LED displays for securities, interest rates, futures and other purposes.
Technical characteristics of LED display:
A. Excellent effect: the use of dynamic scanning technology, stable picture, no noise, clear image effects, vivid and diverse animation effects; smooth video effects; B. Rich content: text, charts, images, animation, and video information can be displayed; C , Flexible mode: The display mode can be arbitrarily arranged by the user; D. Quality assurance: Imported luminescent materials, high-quality IC chips, noise-free high-power power supply are used; E. Large amount of information: The displayed information is not limited; F. Convenient maintenance: Modular design, easy to install and maintain;
