  • Publication number: 20200379333
    Abstract: A projection-type display apparatus includes a light source apparatus, a first optical system with a superimposing lens receiving illumination light from the source apparatus, a second optical system including a first color separator downstream the superimposing lens, mirror, and field lens, and an optical enclosure accommodating the second system. The first separator reflects, toward the mirror, first light in the illumination light belonging to a first wavelength band, and transmits light belonging to a wavelength band excluding the first wavelength band. The mirror reflects, toward the field lens, the first light reflected by the first separator. An angle between an optical axis of the superimposing lens and the first separator is greater than 45° in a first system plan view. A field lens optical axis is substantially parallel to a first system optical axis. The optical enclosure includes a fixing section holding and fixing the first separator.

  • Patent number: 7329007
    Abstract: A projector includes an illumination device, a color separation system, a light combining system, a projection system, and an optical adjustment portion. The color separation system separates the light emitted from the illumination device into blue light, red light, and green light. The light combining system can have a first dichroic filter reflecting one of blue light or red light, and a second dichroic filter reflecting green light which are placed in a crossed state and can combine image lights of respective colors exiting from the first through third light modulation devices. The projection system can project a combined light exiting from the light combining system while correcting chromatic aberrations of magnification of blue light and red light with respect to green light. The optical adjustment portion can adjust a size of an image light corresponding to the green light of the combined light exiting from the light combining system.

  • Patent number: 7168812
    Abstract: To provide a projector that hardly causes deterioration of an image resulted from stray light. A neutral density filter, of which posture can be fine-adjusted by a posture regulating mechanism, is placed in a space between a second dichroic mirror and a liquid crystal light valve. Thus, it is possible to remove stray light, corresponding to condensed light resulted from multi-pass through a field lens or the like, to the outside of a light path by merely tilting the neutral density filter adequately. It is thus possible to project an image having homogeneous brightness (illuminance at the white level) across the entire screen, which in turn makes it possible to project an image having no irregularities in color across the entire screen.
