Abstract: An image display apparatus according to an embodiment of the present technology includes an emitter, an irradiation target object, an optical unit, and a polarization control unit. The emitter emits image light along a predetermined axis. The irradiation target object is disposed in at least a part of an area around the predetermined axis. The optical unit is disposed to be opposite to the emitter by using the predetermined axis as a reference and causes the emitted image light to enter the irradiation target object. The polarization control unit controls a polarization state of the image light that enters the irradiation target object in accordance with a shape of the irradiation target object.

Abstract: A color display has continuous areas of a single color covering a plurality of sub-pixel electrodes. Each sub-pixel of a given color has sub-pixels of the same given color disposed along at least two of its adjacent edges. Each area of a single color may cover a 2×2 array of sub-pixel electrodes. The colors used may be red/green/blue/white (RGBW), red/green/blue/yellow (RGBY), or orange/lime/purple/white.

Abstract: System and method for improving color convergence in projection display systems employs one or more mirror units disposed for reflecting light from the projection lens to a display screen, each mirror unit including one or more reflective layers adjustably positioned for changing the path length of selected one or more color components of the color image.

Abstract: A synthetic color television system includes a color-filter for three primary colors and a brightness-sensitive medium. The color-filtering layers for the three primary colors are sequentially excited between the camera and objects taken by the camera so as to regulate the vertical and horizontal scanning signals and the sequence of signals of the three primary colors read from the brightness-changing signal series, or from a digital or analog source of image signals containing the above-mentioned signals transmitted to a displaying screen. A representation of the three primary color filtering screen displays synchronically the picture in the order of the three primary colors, creating a color picture effect through the persistence of vision on the three primary colors.

Abstract: A dual-mode image display apparatus includes a black-and-white image display device and a selective filter. The selective filter is caused to assume a first mode in which it sequentially serves as red, green and blue filters, and a second mode in which it transmits all the color components. Thus, the image display apparatus can selectively perform color display or black-and-white display. The selective filter may include variable optical retarders and may be caused to selectively assume the first mode or the second mode through control over the variable optical retarders. The selective filter may alternatively be moved by a motor between a first position in which the filter is in the path of light from the display device to the viewer, and a second position in which the filter is out of the path of light. A power supply controller is also used to conserve power by turning unneeded parts of a color image processing circuit OFF when the display apparatus is in the second mode.

Abstract: A projection apparatus creates laser generated visible images utilizing the interference of light principle, and includes individual laser projection devices, positioned and disposed in opposite sets, each structured to emit a select color laser beam which is modified and split by optical phase modulators and beam splitters, respectfully, to form an array of beams which intersect with beams from the oppositely disposed laser projectors to produce the desired multi-colored image. The apparatus is supported above or below the desired area of the generated image with the laser devices mounted on computer controlled motorized swivel mounts, providing the capability to selectively locate the produced images at various preprogrammed locations within a defined area.
