Abstract: An electrical circuit includes a switch having an on state and an off state for connecting a single drive current power source in series with an electroluminescent device for each electroluminescent device of an electroluminescent device array to conduct a first drive current through the electroluminescent device in the on state. The switch connects an amplitude shift load in series with the electroluminescent device and the drive current power source to conduct a second drive current through the electroluminescent device in the off state. The first drive current and the second drive current constitute an amplitude shift modulated drive current through the electroluminescent device. A control signal generator receives a digital switch command for each electroluminescent device from an electroluminescent device controller and generates an amplitude shift control signal to cause the switch to switch between the on state and the off state for regulating an average of the amplitude shift modulated drive current.
