Screen control system

Abstract

A screen control system includes a source controller, a plurality of serial units and a plurality of forward channels. The plurality of serial units are coupled in series, coupled to the source controller, and configured to control a display screen. Each of the plurality of forward channels is coupled between two of the plurality of serial units or between one of the plurality of serial units and the source controller, configured to forward a video data and a command to the plurality of serial units from the source controller. The plurality of forward channels couple the source controller with the plurality of serial units to form a closed loop.
