Abstract
A display device scans a phosphor screen with three independently modulated ultraviolet beams. The screen is coated with three types of light-emitting phosphor dots, each emitting a different color of visible light when illuminated by ultraviolet light. A color separator such as an aperture mask or lens array directs each ultraviolet beam onto phosphor dots of one of these three types. Two or more of these display devices can be combined to obtain a larger screen size.
