Ultra-long loading system

◉ Ultra-long large screen display data stream high-speed output technology

With the continuous expansion of application fields, the demand for large LED screens is increasing day by day. The concept of the strong and the strong in the law of the jungle has also been transferred to the LED commercial display field. More and more display applications, such as large-scale supermarkets, planning In order to give visitors or customers a strong visual impact on the owners of museums, museums, hotels, football stadiums, basketball courts, etc., in many cases, LED displays are getting larger and larger in a certain size direction, which controls this type of display. The plan also puts forward higher requirements. In order to solve this demand, Mermaid Optoelectronics took the lead in proposing an overall solution for the ultra-long (high) load-bearing display, and it has been recognized by customers in the practical application of many cases. Because the control of LED display screens is more complicated, especially for the occasions of super long LED display screens and special effects, the processor is required to have fast calculation speed and high execution efficiency, so this control scheme is mainly designed based on high-end equipment. While properly selecting high-performance devices, we also noticed that the organization of display data has an irreplaceable and important role in improving system performance. The combination of software and hardware can give full play to the advantages of the device. For an ultra-long LED display, the horizontal or vertical arrangement of many pixels is a test for the transmission speed of the display data. In order to solve the problem of the slow data output speed of the ultra-long LED display, Mermaid Optoelectronics started with the display data organization method, output control timing and program optimization, combined with the advantages of the supporting single-chip hardware, and provided an implementation plan for the ultra-long load control system.

◉ System structure

Display information

Pixels: 11776*256 Cabinet: 256*256 Point pitch: P3 Two four-port sending cards are used for discount processing when swiping the screen. Each card carries 23 boxes, the sending card's network port 1 network port 2 network port 3 carries 6 boxes, and the four network port carries 5 boxes. The box body is swiped into a screen with 6 columns and 4 rows, and the two sending cards are swiped into the same, using 570E stitching. The input adopts DP input 3072*1024, custom-made discount video source, to achieve point-to-point playback, no amplification and compression!

◉ Application

This solution is mainly used for super long, super wide, super large LED display screen load point control.
