摘要:
Disclosed is a projector optical system, the system including an illumination unit including illumination lenses illuminating light downwards, a display device receiving light illuminated from the illumination lenses to enable to realize an image, projection lenses downwardly projecting light emitted from the display device to a screen, and a field lens changing an optical angle of the light illuminated from the illumination lenses and emitting the light to the display device, and changing an optical angle by receiving an image light of the display device and emitting the light to the projection lenses.
