  • Patent number: 7027201
    Abstract: An optical modulation element is capable of forming a reflective diffraction grating in which heights of a plurality of elements each having a reflecting surface periodically change. The reflecting surfaces of at least one of the plurality of elements are driven in a direction of height by piezoelectric elements. The plurality of elements each having the surface as the reflecting surface are two-dimensionally arrayed by juxtaposing long sides. A rear surface side of an effective reflecting portion of each of the elements is fixed to the piezoelectric element.

  • Publication number: 20040046910
    Abstract: A display apparatus is constituted by a planar display device and a planar illumination device therefor. A lowering in light quantity at a periphery of the planar illumination device is prevented by inserting a reflection member, such as a reflection frame, having an inside reflection surface along the periphery of the illumination device, or a combination of a scattering means and a transparent sheet member between the display device and the illumination device. A plurality of the display apparatus may be combined to allow an associate movement thereof so as to constitute a composite display apparatus, such as a head-mount display.

  • Patent number: 6608621
    Abstract: An image displaying method and apparatus is provided which can display an image at a high luminance. A first horizontal line image signal is written in a write memory, read in parallel from a read memory during a horizontal blanking period next to the horizontal image signal period, and amplified to thereafter perform modulation. The first horizontal line image signal is displayed at least until the next horizontal image signal line period terminates. The above operations are sequentially repeated to scan all horizontal lines.
