摘要： A color active matrix display system allows random access of pixel electrodes. The control electronics is fabricated with the active matrix circuitry using single crystal silicon technology. The control electronics includes a random access data scanner and random access spec scanners. By selectively actuating pixel electrodes in the active matrix display region, compressed video information can be directly displayed on the active matrix display panel. Color stripes are used to generate sequential color systems to produce a color image from the active matrix display panel.

摘要： In a single panel scrolling raster projection system of the type having a single light source, a single light valve panel, a rotatable element having surface segments for separating the white light into color bands, and field-sequential, line-at-a-time addressing means, one or more of the color bands is sized to have a height in the scrolling direction greater than the height of the panel in the scrolling direction, and sizing the remaining bands to have a scrolling height substantially equal to that of the panel. Color correction is achieved by changing the power of the light source to increase or decrease its illumination during the period in which the panel is substantially entirely illuminated by a color band having a scrolling height greater than that of the panel, and/or by adjusting the scrolling heights of the color bands relative to one another.

摘要： A scanning-light-band display apparatus includes a light-valve panel and an optical system. The optical system includes a multicolor light source and a faceted, rotatable light-transmissive polygonal prism. The light source projects illumination rays for forming images of red, green and blue light bands through the prism along different respective paths. A combination of optical components is arranged for intercepting the illumination rays and forming the images on the panel.

摘要： A color projection video system utilizing only a single light valve. A white light source is separated into into red, green and blue bands. Scanning optics cause the RGB bands to be sequentially scanned across a light valve, such as a transmission LCD panel. Prior to each color passing over a given row of panels on the light valve, that row will be addressed, by the display electronics with the appropriate color content of that portion of the image which is being displayed. The image is projected by a projection lens onto a viewing surface, such as a screen. The sequence of light bands occurs so quickly as to give the viewer an appearance of simultaneous full color.

摘要： A digital video display system (100). The system receives digital data from either broadcast video (102) or an alternate source (107), in either analog or digital form. The system processes the data into display data and loads the data onto a digital micromirror device (112). The data is either formatted for color-sequencing or separated into color data for separate devices. The data causes the individual cells on the device to respond and then they are illuminated. The light coming from deflected cells is displayed on a display surface.

摘要： A light source comprising an excitation light source (110) for providing excitation light, and an optical wavelength conversion member disposed at a distance from the excitation light source. The optical wavelength conversion member comprises an optical wavelength conversion material (150) for converting the excitation light into stimulated light. The light source also comprises an optical-guiding member that allows the excitation light to be incident on the optical wavelength conversion material, and an optical-collecting member (130A) for collecting stimulated light originating from the optical wavelength conversion material. To separate the paths of the stimulated light and the excitation light, the etendue of the optical-guiding member is less than or equal to ¼ of the etendue of the optical-collecting member. This allows the optical-guiding member to draw in the excitation light while preventing the excessive escape of the stimulated light through the optical-guiding member. The advantages of the light source are that it can separate the paths of the excitation light and the stimulated light, the light path is simple, and the optical members are easy to manufacture.

摘要： An illumination device includes: an excitation light source that emits excitation light having a first wavelength; a fluorescent substance that, when irradiated with the excitation light, emits light having a second wavelength longer than the first wavelength and transmits a part of the excitation light, and thereby multiplexes and emits the transmitted excitation light having the first wavelength and the emitted excitation light having the second wavelength; and a driving unit that moves an irradiation position of the excitation light in the fluorescent substance with the passage of time.
