摘要： A projector device is disclosed which uses light that is spatially modulated by a DMD having mirrors which are moveable between Off and On positions in response to image information input to the DMD. Images formed at the DMD are projected onto a screen via a projection lens. Surfaces of the lens elements of the projection lens are designed with curvatures such that light that may be undesirably reflected back to the DMD will not be in a converged state at or near the surfaces of DMD mirrors. In this way, ghost light that is projected onto the screen is dispersed over a wider area, and thus is less noticeable and not troublesome.

摘要： In an illumination optical system and a liquid crystal projector apparatus using the same, two lens arrays each comprising linear convex lens arrays with their pitches shifted from each other are used for improving image quality such as not to generate shadows of the cementing ridge of a cross dichroic prism, and a polarization-converting optical system is appropriately disposed, so as to obtain uniform illumination effects efficiently. The vertical angle ridge 71 of four prisms constituting the cross dichroic prism 70 is disposed so as to be orthogonal to the optical axis, the polarization-converting optical system 3 is disposed such that a plane including the vertical angle ridge 71 and optical axis and the direction along which stripes of half-wavelength phase films 32 extend are orthogonal to each other, and the direction of shifting the lens columns of a plurality of linear convex lens arrays constituting the first and second lens arrays 21 and 22 is orthogonal to the plane.

摘要： A projection-type image display device includes a light source, converging optics, a rod integrator having a first optical axis, a light deflecting structure, and a light beam separating structure. The light beam separating structure directs light to a digital micromirror device and modulated light from the digital micromirror device along a second optical axis of a projection lens that projects an image formed by the modulated light on a screen. The rod integrator is between the light beam separating structure and the projection lens in the direction of the second optical axis and is outside the optical path of the modulated light beam from the digital micromirror device. The rod integrator may include a solid rod member and a leaky ray shielding member at least at one of the entrance end, the exit end, and around the solid rod member. The converging optics may include a parabolic reflector and an aspheric lens.

摘要： A projection type image display apparatus makes illumination light from a light source section incident on a rectangular reflection type liquid crystal display device by way of a polarization beam splitter, optically modulates the illumination light in the reflection type liquid crystal display device, and projects thus modulated light through a projection lens by way of the polarization beam splitter. A plane including the optical axis of illumination light incident on the polarization beam splitter and the optical axis of illumination light emitted from the polarization beam splitter toward the projection lens is substantially parallel to a direction in which a shorter side of the reflection type liquid crystal display device extends.
