Walking on the street, we often see LED displays. Today, the editor will discuss the LED display with you. In this article, the editor will introduce the working mechanism of the LED display control system. If you are interested, please continue reading. The following is the introduction of "LED display control system introduction and operation manual".
The advanced development process of full-color LED display and LED electronic display is like a "mystery", curious and intriguing; the working principle of LED display, LED electronic display control system, LED display, LED electronic display control system is What? How can we understand the LED display and LED electronic display control system more comprehensively and accurately? This is exactly what LED electronic display manufacturers should discuss with everyone.
LED display control system (LEDDisplayControlSystem), also known as LED display controller, LED display control card. It is the core component of the LED display, which is mainly responsible for receiving screen and video display information from the computer serial port or DVI interface, putting it into the frame memory, and generating serial display data that can be recognized by it. The LED display is driven according to the partition. And scan control time.
LED display asynchronous control system: LED display asynchronous control system is also called LED display offline control system or offline card. Mainly used to display various texts, symbols and graphics or animations. The information displayed on the screen is edited by the computer, placed in the frame memory of the LED display through the RS232/485 serial port, and then displayed on the screen through the screen, the display mode is rich and colorful. Its main features are: simple operation, low price and wide range of use.
The simple asynchronous control system of the LED display can only display digital clocks, text, and special characters. In addition to the functions of the simple control system, the LED display graphic asynchronous control system can also control the display screen content by area. Support analog clock display, picture, table and animation display. With timing switch, temperature control, humidity control and other functions.
The LED display is composed of LED dot matrix and ledpc panel. Red, blue and green LED lights are used to display text, pictures, animations and videos. The content can be changed at any time. Each component is a modular structure. equipment.
At present, the application field of LED display is very extensive, and people realize that the growth potential is also a rapidly developing LED application market. In 2008, the LED display market was approximately RMB 1 billion. With the holding and preparation of major events such as the Olympics, World Expos, and Asian Games, large-scale applications of stadiums, airports, stations, banks, hospitals, public squares, commercial venues and residential communities, LED market display applications continue to expand.
The beautiful LED display is suitable for the stage of the grand theater. The clear and smooth picture shocked the audience and colleagues at the scene. It presents the splendid and wonderful performance of the party project in multiple directions and angles. It has become a part of stage art, which makes the chairman and head of state come to observe it full of praise.
The LED display used in the Grand Theater is 28.8 meters long and 12 meters wide, with a total area of 345.6 square meters. It uses LUXON patented 2427 patch black light. The entire large screen has the characteristics of high contrast and large viewing angle, which is fully suitable for high brightness. Compared with other traditional LED indoor large screens, dot correction technology and high-efficiency energy-saving technology can save 50% of energy costs.
It has the following characteristics:
1. Degree: The pixel pitch is 4.615mm, and the unit display resolution is high, which is suitable for high-definition image display.
2. High gray scale: 16384 high gray scale, the image effect is better and smoother;
3. Wide viewing angle: The patented 2427 patch black light has a wide viewing angle and high contrast, which can meet the viewing needs of different angles;
4. High refresh: use constant current IC that supports high refresh and high gray, refresh frequency ≥ 2000HZ.
5. Control system: large-scale display control is stable, no black screen, no jitter, no block diagram;
6. Calibration technology: optimize the visual effect of the LED screen, improve the quality of the LED screen, the service life of the LED screen, reduce the cost of the LED screen, and ensure the image display quality of the display;
7. Cabinet structure: full die-cast aluminum structure, modular unit design, fast and convenient screen splicing.
8. Connector: The signal and power plugs are quick plug-in aviation plugs, which can quickly realize the signal and power connection.
