Abstract:
1. A display device that produces a visible image in response to an input image signal having a plurality of components, comprising: a screen, including a base plate and a wavelength converting coating responsive to output light of a first visible wavelength range in response to light of a first input wavelength, and responsive to output light of a second visible wavelength range in response to light of a second input wavelength; a first light emitter operative to emit a first modulated beam of light of the first input wavelength in response to a first component of the image signal; a second light emitter operative to emit a second modulated beam of light of the second input wavelength in response to a second component of the image signal; and a scanner assembly having an input aligned optically to receive the first and second modulated beams of light from the first and second light sources and an output aligned optically to direct the beams received at the input to the screen, the scanner assembly being responsive to a driving signal to scan the received beams onto the wavelength converting coating in a periodic pattern; and wherein the wavelength converting coating includes a first infrared sensitive phosphor compound and the first input wavelength is an infrared wavelength.
