Abstract
Implementations of display systems and devices based on scanning light on a light-emitting screen where at least one excitation optical beam is used to excite one or more light-emitting materials on the screen which emits light to form images. The light-emitting materials may include fluorescent and phosphor materials. A control mechanism is described to reduce the spatial variation in screen brightness.
