摘要： Method of energizing a primary modulator (620) in a dual modulation projector wherein a pre-modulated light (615) comprising re-directed light illuminates the primary modulator (620). The method comprises the step of preparing a re-directed Light Field Simulation (LFS) at the primary modulator (620), said re-directed LFS accounting for lights previously on paths from a light source (605) to locations on the primary modulator (620) corresponding to a dark area or dark areas of an image to be modulated being re-directed to another location or other locations on the primary modulator (620) corresponding to a bright area or bright areas of the image to be modulated. The method further comprises the step of energizing the primary modulator (620) according to the re-directed LFS and image data (640) representing the image.

摘要： It is to provide a projection type display apparatus which enhances the contrast performance while minimizing a reduction in the brightness by blocking a light beam which would decrease the contrast through the use of diaphragms provided in both of an illumination optical system and a projection lens.
[Solution] A light source portion 1 and 2, a first lens array 4, a second lens array 5, and a superposition lens 7 constitute an illumination optical system. An illumination diaphragm 8 located in the vicinity 7 of the second lens array becomes a diaphragm aperture in a rectangular shape when being narrowed, wherein a side of the diaphragm aperture in the rectangular shape and longer side directions of the lens cells of the second lens array 5 are perpendicular or parallel to each other. A liquid crystal display device 17 modulates incident light. A projection lens 19 enlarges and projects modulation light. A projection lens diaphragm 20 becomes a diaphragm aperture in a rhombus shape when being narrowed, wherein a diagonal line of the diaphragm aperture in the rhombus shape and directions of sides of lens cells in a pupil image of the second lens array 5 which is formed in a pupil position of the projection lens are perpendicular or parallel to each other.

摘要： Some projection systems use a polarization beamsplitter (PBS) for coupling light to and from an image-forming device. The PBS is typically formed with a reflective polarizing layer disposed between glass covers. Stress birefringence in the glass cover lying between the reflective polarizing layer and the image-forming device can reduce the image contrast of the projection system. A quarter-wave retarding element positioned between the glass cover and the image-forming device is used to compensate for the birefringence, at least in part. This permits the PBS to use glass covers formed of a glass material having a higher stress optic coefficient than before, while still maintaining high image contrast.

摘要： A compact and efficient optical system featuring planar multi-layered LED light source arrays concentrating their polarized or unpolarized output within a limited angular range. The optical system manipulates light emitted by a planar light emitters such as electrically-interconnected LED chips. Each light emitting region in the array is surrounded by reflecting side-walls whose output is processed by elevated prismatic films, polarization converting films, or both. The optical interaction between light emitters, reflecting sidewalls and the elevated prismatic films create overlapping virtual images between emitting regions that contribute to the greater optical uniformity. Practical illumination applications of such uniform light source arrays include compact LCD of DMD video image projectors, as well as general lighting, automotive lighting, and LCD backlighting.

摘要： An illumination optical system and a projection display apparatus include a beam combining portion (4) and a condensing lens (8) condensing a beam from the beam combining portion. The beam combining portion combines beams from first and second lamp units each including a lamp and a concave mirror, the lamp having a cathode and an anode arranged along an optical axis of the concave mirror. The beam combining portion includes a first reflective section (31B) disposed on an optical axis of the first lamp unit and off the optical axis of the second lamp unit and a second reflective section (32B) disposed off the optical axis of the first lamp unit. The first and second reflective sections reflect a beam that is emitted from the second lamp unit and that is off an optical axis thereof to combine the beams from the first and second lamp units.
