Abstract

The invention provides an optical fiber transmission system for an LED display screen. The system includes a power supply box used for supplying power, an upper computer, video processing units, an SFP module transmitting unit used for converting video electric signals to optical signals, an SFP optical module receiving unit used for converting optical signals to electric signals, a signal processing unit used for processing electric signals, and a display drive unit used for converting video signals of the signal processing unit to differential signals and driving the LED display screen. The power supply box is connected to the video processing units and the signal processing unit through power lines. The video processing units are connected to the SFP optical module transmitting unit. The SFP optical module transmitting unit is connected to the SFP optical module receiving unit through an optical fiber. The signal processing unit is connected to the SFP optical module receiving unit and the display drive unit separately. The video processing units are in cascade connection through DVI wires. Therefore, long-range large-screen LED display screen video display is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of LED video transmission, and in particular to an optical fiber transmission system for LED display screens. Background technique [0002] At present, LED display technology has become increasingly mature, and the LED display control system is mainly used to display video, graphics, notifications, etc. in real time. One of the functions of its main control circuit is responsible for data input and transmission. Usually, the main control circuit receives the data sent by the upper computer, and after processing by the controller, the wired cable is used as the transmission medium to transmit the processed video data to the display system, and finally achieve the purpose of display. [0003] Traditional LED display control systems mostly choose twisted pair or coaxial cables as transmission media. Due to their own defects, their transmission rate and transmission distance have certain l...
