<p>A projector system comprises an illumination-optical system ( 1 ), a colorseparating system ( 4 ) which separates light coming from the illumination-optical system ( 1 ) into at least three beams of colored light (R,G,B), the system further comprising, for each beam of colored light, a modulation device ( 16, 18, 19 ) for modulating the beam of colored light, and a color combiner ( 20 ) which combines the modulated color beams. The projector system comprises a polarization conversion system (PCS) for at least one colored beam and no polarization conversion system for at least one of the other colored beams.</p> |
