Abstract

The invention discloses an LED display screen control method and system. The control system comprises a video signal processing module located at the front end, and an LED display screen drive module located at the rear end and connected with an LED display screen. The video signal processing module is used for receiving video signals from a video source, processing the video signals, converting the video signals into serial digital signals, and transmitting the serial digital signals to the LED display screen drive module through multiple coaxial cables, wherein BNC connectors are arranged at the two ends of each cable. The LED display screen drive module is used for receiving the serial digital signals, generating display data including the gray level, luminance and chroma according to the serial digital signals and driving the LED display screen to display digital data. The coaxial cables with the BNC connectors at the ends are adopted as the transmission medium, and therefore transmitting and displaying of ultrahigh-definition videos are supported, and screen blank, flash and various other display faults caused by unstable circuit connection can be avoided.
