Abstract
This specification describes phosphor compositions used in fluorescent layers for scanning beam displays. In general, one aspect of the subject matter described in this specification can be embodied in a display device having a fluorescent layer that absorbs an excitation light at a single wavelength and emits visible light. The fluorescent layer includes a plurality of parallel fluorescent stripes. At least three adjacent fluorescent stripes are made of three different fluorescent materials, which include a first fluorescent material that absorbs the excitation light and emits light of a first color, a second fluorescent material that absorbs the excitation light and emits light of a second color, and a third fluorescent material that absorbs the excitation light and emits light of a third color.
