In the rapid development process of today’s modern information society, LED display has penetrated from commercial applications such as public information display to consumer multimedia applications. With the development of broadband network, digital multimedia content will occupy the mainstream in the information world, and new LED screen display equipment will replace the traditional TV to become the center of people’s enjoyment of information and multimedia content.
Outdoor LED Display Application
LED display control system concept
LED Display Control System (LED Display Control System), also known as LED display controller, LED display control card. It is the core component of the LED display, mainly responsible for receiving the screen and video display information from the computer serial port or DVI interface, placed in the frame memory, according to the partition drive mode to generate the serial display data and scan control timing that the LED display can recognize.
LED display system composition
LED graphic display system is composed of software control system, wireless transmission system, equipment master controller, LED display lattice, power supply and other parts.
LED display system operation process
The main tasks of the software control system are graphic editing, font extraction and saving, image preview and file transfer. The wireless transmission system mainly completes the transmission of file information from the PC to the LED display, and the main task of the LED dot matrix in the hardware control system is to complete the information display through the current control, and drive the LED dot matrix ranks through the control of the scanning drive mode of the single-chip computer to achieve the device drive and finally achieve the received graphic display function.
1. the signal source can be a camera, laptop, desktop computer, DVD and other video output equipment;
2. the signal through the video processor, converted into DVI signal, through the DVI line connected to the sending card;
3. the distance between the control room and the display screen is greater than 100M, the use of optical fiber conversion card, the use of optical cable communication
4. each display box has a receiver, the receiving card is connected by network cable communication.
5. because the display is T-shaped appearance, the system transmission adopts the communication mode from the bottom up.
6. the display can play a variety of content, you can switch the input source.
7. the use of cameras can play real-time video signals to the display screen, you can also link to digital set-top boxes, play TV conten.
8. you can use the playback software to play the pre-processed video picture information on the computer.
LED display control system
LED display VS traditional display device
Compared with traditional display devices, this huge demand in the future makes large-screen display technology the focus of attention:
LED display is rich in color, diverse display modes (graphics, text, three-dimensional, two-dimensional animation, TV screen, etc.), high brightness, long life, is an epoch-making product of information communication facilities;
LED display is a set of optoelectronic technology, microelectronics technology, computer technology, information processing technology in one of the high-tech products, can be used to display text, computer screen synchronization graphics. It is a widely used display system in the world because of its large screen, super vision, flexible display mode and other advantages.
LED display is widely used, financial securities, bank interest rates, commercial advertising, culture and entertainment, etc., there are huge social benefits and rich economic benefits.
Thank you for watching, I hope it can solve your problem
