Claim:
1. A scanning beam display system based on phosphor materials, comprising: an excitation light source to produce one or more excitation beams of the same wavelength having optical pulses that carry image information; a beam scanning module to receive the one or more excitation beams and to scan the one or more excitation beams; and a light-emitting screen positioned to receive the one or more scanning excitation beams and including light-emitting phosphor materials which absorb light of the one or more excitation beams to emit visible light to produce images carried by the one or more scanning excitation beam, wherein the light-emitting phosphor materials include a composite phosphor material that is a mixture of one or more red emitting nitride phosphors and one or more orange-red emitting silicate phosphors and emits light of a desired red color.
