摘要： The present invention provides an inexpensive projection display that allows a pixel grid as ineffective portions of respective pixels of a light valve to be made inconspicuous. The projection display includes a birefringent element (43) for spatially separating light from a transmission liquid crystal light valve (39). The birefringent element (43) includes a first birefringent plate (40) that the light from the liquid crystal light valve (39) enters, a second birefringent plate (41) that light from the first birefringent plate (40) enters, and a third birefringent plate (42) that light from the second birefringent plate (41) enters. A polarization direction of the light entering the first birefringent plate (40) forms an angle of n×45° (n is an integer other than 0) with an optic axis of the first birefringent plate (40) projected on an incident surface of the first birefringent plate (40). An optic axis of the second birefringent plate (41) projected on an incident surface of the second birefringent plate (41) is orthogonal to the optic axis of the first birefringent plate (40) projected on the incident surface of the first birefringent plate (40). An optic axis of the third birefringent plate (42) projected on an incident surface of the third birefringent plate (42) extends horizontally or vertically.

摘要： A white light beam from a light source portion (201) is separated into respective light beams of red, green and blue by a color separation optical system (204). The respective light beams are reflected by a rotating polygon mirror (207), travel via a second optical system (210) and form belt-like illuminated regions on an image display panel (212). By a rotation of the rotating polygon mirror (207), the illuminated regions of the respective light beams move continuously, and each pixel of the image display panel (212) is driven by a signal corresponding to a color of light entering this pixel. An image on the image display panel (212) is magnified and projected onto a screen by a projection optical system (216). The color separation optical system (204) has first and second reflecting mirrors that respectively reflect the respective light beams of red, green and blue, and these reflecting mirrors are arranged so that optical paths of the respective light beams have equal lengths from the light source portion (201) to the rotating polygon mirror (207). This makes it possible to provide a small projection-type image display apparatus that has a high efficiency of light utilization and can display an image with high resolution and enhanced color uniformity.

摘要： A projection display system includes: two light sources (102, 105); a condenser (103, 106) for condensing the light from the light sources; a time-division color separating optical system (108) for temporally switching the incident light into a first, second, or third color of light to be emitted; a light valve (118) capable of modulating the incident light individually for each pixel; a lighting optical system (111, 112, 114) for directing the light from the time-division color separating optical system onto the light valve, and a projection optical system (123) for magnifying and projecting a pixel on the light valve. The light from the two light sources (102, 105) is condensed on the time-division color separating optical system or its vicinity by the condenser (103, 106), and then superimposed. This can provide a projection display system that performs time-division driving and can achieve high-brightness projection images without increasing the size and cost of a system.

摘要： An image display apparatus is provided for enlarging and projecting a light emitted from a plurality of self-emitting elements on a screen by beam scanning means, which is an image display apparatus having little or no luminance unevenness by solving the conventional problem of causing luminance unevenness in images projected on the screen due to a variance in luminance characteristics of each self-emitting element. It is configured such that a part of the light scanned on the screen from the beam scanning means is provided to a photodetector element that converts the intensity of the light into an electric signal so as to correct a driving signal to be supplied to the self-emitting element by the intensity of the light detected by this photodetector element.

摘要： Three colors of light beams from a light source travel via a first optical system to strike a reflecting surface of a rotating polygon mirror, or mirrors, at different angles without overlapping. The rotating polygon mirror or mirrors reflect the light beams for scanning. The reflected light beams enter a second optical system at different angles to illuminate an image display panel at different portions. On the image display panel, belt-like regions illuminated by the light beams of individual colors are formed in parallel with each other, and these illuminated regions are moved continuously by scanning. A formed color image is magnified and projected by a projection optical system. With such a projection type image display apparatus, a display having high resolution and light efficiency that is also small, thin and inexpensive is achieved.

摘要： Red, green and blue light beams from, a light source portion travel via a first optical system and enter a reflecting surface of a rotating polygon mirror at different angles so as not to overlap each other. The rotating polygon mirror makes these light beams perform scanning when reflecting these light beams. The light beams for the scanning enter a second optical system at different angles and are led to different positions on an image display panel. The second optical system forms an image that is rotated by 90° from that on the rotating polygon mirror on the image display panel. On the image display panel, belt-like regions illuminated by the light beams of individual colors are formed in parallel with each other, and these illuminated regions are moved continuously by the scanning. Each pixel of the image display panel is driven by a signal corresponding to a color of light entering this pixel. A formed color image is magnified and projected by a projection optical system. With such a projection-type image display apparatus, it becomes possible to achieve a display with a high efficiency of light utilization and a high resolution. In addition, since the second optical. system rotates the light beams from the rotating polygon mirror by 90° and then leads them to the image display panel, a widely-used image display panel can be used. Accordingly, an image display apparatus that is small, thin and inexpensive can be achieved.
