摘要:
A projector apparatus includes a light source for producing light beams, a micromirror device including an array of micromirrors for modulating and reflecting the light beams into image light beams, and a projection lens unit for magnifying and projecting the image light beams. The projection lens unit includes an optical lens disposed adjacent to the micromirror device, and a light shielding plate mounted on the optical lens or between the micromirror device and the optical lens for covering bias light so as to prevent formation of a ghost image in the projected image.
