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 video color image projector which includes a block of crossed dichroic mirrors for combining the light rays from image rasters on respective monochrome image display devices and a projection lens for projecting the composite color rays so as to form an enlarged color image on a display screen. Each display device has a faceplace which is convex on the interior surface thereof and having thereon an interference filter in the form of an internal angularly reflecting coating (IARC). Each faceplate is liquid - coupled to a negative power lens element, so that the faceplate, coupling liquid (or gel) and such lens element effectively constitute a single negative power field flattener lens at each entrance side of the dichroic block. The composite color rays at the exit side of the dichroic block are projected on the display screen by an assembly of lens elements which includes at least one optically positive lens element. The focal length of the complete projection lens formed by such assembly and each of the negative field flattener lenses may be from 0.5 to 0.9 times the diagonal D of the image raster on each display device, so that the projector is sufficiently compact to be included in a cabinet suitable for consumer television receivers.

摘要： A circuit for correcting raster distortion on a CRT display screen. Horizontal distortion is corrected by overscanning and providing complementary modification of the time delay and data rate at which digital video data is supplied to the CRT during each scanning line. The video data for a given scanning line is stored in a line store, read-out therefrom being controlled by a microprocessor programmed to determine the necessary time delay and data rate of such read-out. Vertical distortion, affecting scanning lines in the vicinity of the top and bottom of the raster, is corrected by storing in a multiline store the video data for all such scanning lines. The same or a further microprocessor is programmed to re-assign the video data for pixels on each of such lines to vertically corresponding pixels on others of the scanning lines, such re-assignments being complementary to the vertical distortion of the original scanning lines.

摘要： A wide screen television monitor capable of displaying standard width picture in which uneven "Coulomb aging" is minimized. The television monitor includes circuitry for causing the standard width picture to cyclically traverse the width of the display screen of the television monitor in accordance with a prescribed function. The period of repetition of this movement is of such a duration that a casual observer of the television monitor is unaware of the movement of the picture.

摘要： A projection system includes first and second light sources which are disposed at an angle with respect to each other and are activated during respective different phases of an illumination cycle to illuminate a spot on different sides of a segmented rotary filter wheel. The filter wheel is alternately used to transmit light from one of the light sources, and to reflect light from the other light source, to a light valve, the output of which is projected onto a screen. The wheel segments may be alternately clear and mirrored or may alternately transmit and reflect colors to produce color sequential illumination of the light valve. In addition to filter wheels producing sequences of red, blue, green illumination, including the possibility of splitting a color phase into non-adjacent smaller phases to reduce color artifacts, a simple filter wheel which in two rotations produces a sequence of red, blue, green, cyan, magenta, yellow color illumination, resulting in an expanded color gamut, is also disclosed. Blanking intervals during which both lamps are turned off span each passage of a segment boundary through the spot.

摘要： A two-source illumination system includes a reflective array of elements deflectable to first and second positions in response to a drive voltage, and two sources pointed at the array from different angles, so that upon cycling the elements rapidly back and forth between the two positions, and alternately cycling the sources between on and off conditions synchronously with the cycling of the reflective array, light from both sources is (alternately) reflected back along an axis normal to the array. This arrangement allows driving the sources at a higher power level, resulting in a higher total light output from the system than would be possible with a single source driven constantly at a lower power level.

摘要： The present invention is directed to illumination structures useful in display systems for projection video and television devices performing with high efficiency and good color rendition. Such illumination sources include a light source having an inner and outer envelope with plane mirrors within the outer envelope to direct reflected light, a light source providing randomly polarized light with polarizing structure for passing a desired polarization of the polarized light, and an arc lamp having at least two arcs for supplying uniform illumination in two dimensions. These illuminating structures enable significantly improved illumination in the appropriate projection video and television systems.

摘要： Display systems useful for projection video and television systems are provided to perform with high efficiency and good color rendition. In these systems, color may be provided, as one example, by various light valves, such as liquid crystal displays. Each of the liquid crystal displays are positioned at equal path distances from an illuminating subsystem, and have equal path distances from the light valves to a projection subsystem. This enables optimum illumination of each of the light valves. Various embodiments of arranging the light valves, as well as providing illumination are described.

摘要： A video projection system using a light modulating display device having a row and column matrix of picture elements is improved by imparting an oscillatory motion to the display image in the plane of the image, to thereby reduce the visibility of the individual picture elements of the matrix. The resolution of the image can be increased by displaying different video information at different parts of the oscillatory cycle.
