Display management is computerized and controlled by a remote-located desktop computer for feeding the required information. Signal processing for displays involves operations such as digitization of signals, image resizing, video mixing, color adjustments, and so on. A coaxial or ber-optic cable inputs the data from the control unit to the LED driving circuit. Multiplexing and pulse width modulation techniques are ordinarily used in these systems.
