摘要： An optical position of a display device with respect to an optical axis of a projection optical system is displaced in a direction perpendicular to the optical axis in accordance with a change in the size of a projected image. For instance, a transparent flat plate is disposed in front of a projection lens, and the transparent flat plate is tilted in association with a rotation of a zoom adjustment ring. As the transparent flat plate is tilted, the apparent position of the display device relative to the projection lens is displaced in the direction perpendicular to the optical axis of the projection optical system. Thereby, the projected image on a screen is located at a proper position corresponding to a zoom state. Tilt control of the transparent flat plate is realized by a cam mechanism, for instance.

摘要： A projection display device comprises a projection lens section to which light modulated by a light modulating element is entered, a mirror section for reflecting the light emitted from the projection lens section to reflect to the projection lens section side and directing the light to a projection plane, and an operation section for displacing a lens in the projection lens section. The operation section is disposed in a region in which the operation section does not hinder an optical path of the light that has been passed through a projection port provided in a main body cabinet.

摘要： A rear projection display, not requiring a dichroic prism, and capable of rendering a generation system of each image light in color independent of the other generation systems so as to optimally construct and improve easiness of assembly of, and so on, each generation system, is provided. Each unit for projecting image-light is formed of an LED array, a rod integrator, a liquid crystal display panel, and a projection lens. A projection optical axis of the projection lens of each unit for projecting image-light is parallel each other. A unit for projecting image light in red is provided with an LED array for emitting light of a wavelength band in red, a unit for projecting image light in green is provided with an LED array for emitting light of a wavelength band in green, and a unit for projecting image light in blue is provided with an LED array for emitting light of a wavelength band in blue. Each image light in color obtained as a result of passing through the liquid crystal display panel is projected by the projection lens, and displayed on a screen. As a result, each image light in color is superposed on the screen, and an image in full color is displayed.

摘要： An ion wind generator is arranged in the vicinity of a light source. The ion wind generator allows an air flow by negatively ionizing air by corona discharges using negative side needle electrodes, and drawing the negatively-ionized air using a ground side mesh electrode. High-temperature air surrounding the light source is drawn by the air flow and exhausted from an exhaust port at a rear side of a casing. An ozone decomposition catalyst filter is provided in the exhaust port. Ozone (O3) is generated by the corona discharges in the ion wind generator. However, the ozone is decomposed by passing through the ozone decomposition catalyst filter provided at the exhaust port.
