ABSTRACT:
An alphanumeric and graphic symbol display device in which an LED array is rotated and controlled to project a display onto a translucent surface. The electrical power for the array is provided by way of a rotating contactless transformer independently of the control data for the array which is provided by infrared data transmission through a tubular shaft driven by a DC brushless, three-phase motor to rotate the array at a predetermined rate independent of the electrical power for the array and the control data.
