Patent ID: 7416306

Claim:
A laser projector which modulates laser beams, and projects the modulated laser beams, comprising: short-wavelength laser sources that emit at least laser beams of three colors of red, blue and green; a modulation unit that modulates the laser beams from the laser sources on the basis of a picture signal; and a screen onto which the modulated laser beams are projected, wherein said screen has characteristics of reflecting incident light such that reflection peaks for the incident light are located at wavelengths of the at least laser beams of three colors of red, blue and green, which are emitted from the short-wavelength laser sources, and at neighboring wavelengths, and wherein a projection room in which the screen is placed is illuminated by illumination light that has significantly low levels of wavelength components corresponding to the wavelengths of the at least laser beams of three colors of red, blue and green, which are emitted from the short-wavelength laser sources.
