Video control system and method of LED color difference compensation

The present invention provides a video control system and method of LED color difference compensation. The system comprises a DVI input unit which is connected to a host machine through a DVI cable and is used for receiving the video signal sent by the host machine and sending the video signal to a DVI decoding unit, the DVI decoding unit, a video processing unit, a line driving unit and a control unit. The control unit is used for sending LED lattice conductive wire resistance information to the video processing unit. The DVI decoding unit is used for converting the video signal into R, G, and B component signals and sending the R, G, and B component signals to the video processing unit. The video processing unit is used for receiving the LED lattice conductive wire resistance information and the component signals, carrying out color difference compensation on the LED lattice according to the LED lattice conductive wire resistance information, and sending the component signals and color difference compensation data to the line driving unit. The line driving unit is used for converting the component signals and the color difference compensation data into differential signals. The LED video color difference compensation control is realized by the invention.
