Abstract: A color liquid crystal projector has an optical system for color splitting. The optical system includes a mirror for reflecting a first primary-color light and transmitting second and third primary-color lights in light from a light source; a first phase plate for transmitting the second primary-color light from the mirror with its polarization degree rotated through 90°, and for transmitting the third primary-color light; a first prism for transmitting the second primary-color light from the first phase plate into a second liquid crystal display panel, and reflecting the third primary-color light from the first phase plate into a third liquid crystal display panel; a second prism for entering the first primary-color light from the mirror into a first liquid crystal display panel; and a dichroic prism for combining the first, second and third primary-color lights reflected from the liquid crystal display panels.

Abstract: A display pixel range between a display start position and a display end position of a distortion corrected image is determined on each horizontal line of the image forming section, based on horizontal correction parameters representing distortion-correction amounts at left- and right-sides of the distortion-corrected image to be supplied to an image forming section for forming an image to be projected onto a screen, and a first relation between each pixel within the display pixel range and each pixel in the original image is determined. A display line range between a display start line and a display end line of the distortion corrected image is also determined on the image forming section, based on vertical correction parameters representing distortion-correction amounts in the vertical direction of the distortion-corrected image, a second relation between each line within the display line range and each line in the original image is determined. The distortion-corrected image is produced from the original image according to the first and second relations. This allows easy correction of image distortion due to tilt projection of images onto the screen.

Abstract: An on-vehicle display unit projects an image, which is displayed on a display in a dashboard, on a screen disposed outside the dashboard. The screen is transparent so that the foreground is visible through the screen with the image projected on the screen being superimposed over the foreground. A reflecting mirror is disposed in the dashboard for reflecting light emitted from the image displayed on the display toward the screen. A semi-transparent mirror is disposed in the dashboard between the display and the reflecting mirror. The semi-transparent mirror is able to pass partially and to reflect partially light emitted from the image on the display. An angle changing mechanism selectively changes the semi-transparent mirror relative to a longitudinal direction of the vehicle into a first inclination angle position or into a second inclination angle position. The semi-transparent mirror partially reflects the light emitted from the image displayed on the display toward the screen when the semi-transparent mirror is at the first inclination angle position, and the semi-transparent mirror partially reflects the light reflected by the reflecting mirror toward the screen when the semi-transparent mirror is at the second inclination angle position.

Abstract: A color projector for correcting chromatism by changing the sizes or positions of three display devices with respect to each color is provided. In the color projector, two or more display devices selected from the first through third display devices have different sizes of effective areas where an image is formed such that chromatism generated while lights of different colors synthesized by the synthesizing device pass the projection lens unit can be corrected. Also, the distances between two or more display devices selected from the first through third display devices and the projection lens unit are different from one another such that chromatism generated while lights of different colors synthesized by the synthesizing device pass the projection lens unit can be corrected.

Abstract: The present invention to provides a projection system for three-dimensional movement of projected modulated beam. It comprises a stationary light source, a projection lens, an optical path from the light source to the projection lens and a light beam modulating element in the optical path. The light modulating element moves with the projection lens. The image is generated at a location whereafter the modulated beam is not deflected anymore before arriving at the projection lens. Therefore there is no rotation of the modulated light beam around its own optical axis, independent of the direction of projection.

Abstract: In a projection display device, a main board that is substantially perpendicular to a plane defined by optical axes of an optical unit is allowed to stand aside the optical unit. Therefore, if the main board is designed to have a small vertical size, the vertical size, i.e., the thickness of the projection display device, can be reduced. Therefore, unlike the conventional projection display device in which the main board is disposed above the optical unit, the entire device can be reliably reduced in thickness and size regardless of the thickness of the main board.

Abstract: In a projection display device which can be controlled by a remote controller, the remote controller includes a power supply switch button for turning on/off a power supply at a body of the projection display device, a zoom adjuster button for adjusting the zooming of a projection lens, and a focus adjuster button for adjusting the focusing of the projection lens. The projection display device body includes a restricting system which can restrict the adjusting functions of these buttons, so that inadvertent operation of any of these buttons does not affect the projection display device.
