  • Patent number: 8270061
    Abstract: The present invention provides a display apparatus, comprising: a light source; at least one spatial light modulator for modulating a luminous flux emitted from the light source; and a controller for processing inputted video image information and for controlling the light source and spatial light modulator, wherein the controller controls the light source and spatial light modulator so that the light source performs pulse emission for a period shorter than a period in which the spatial light modulator is controlled under a modulation state.

  • Publication number: 20090273825
    Abstract: The present invention aims at providing a mirror device, comprising a plurality of mirror elements, wherein each of the mirror elements comprises a deflectable mirror, and an elastic member for deflectably supporting the mirror, wherein the mirror allows to be controlled under a first deflection control state in which incident light is reflected toward a first direction, a second deflection control state in which the incident light is reflected toward a second direction, and a third deflection control state in which the mirror oscillates between the first deflection control state and second deflection control state, wherein the mirror device reproduces gradations by combining the first through third deflection control states, and the natural oscillation cycle T of the oscillation system constituted by the mirror and elastic member satisfies: 110 [?sec]>T=2?*?(I/K)>2 [?sec], where “I” is the moment of rotation of the oscillation system and “K” is the spring constant of the elastic member.

  • Publication number: 20090180039
    Abstract: A video display system includes a plurality of primary color light sources; and a spatial light modulator (SLM) for modulating an illumination light emitted from at least one of the plurality of primary light sources. The video display system further includes a display controller for controlling a process to display a sequence of video images within a period of one frame comprising each of a plurality of primary colors and each of a plurality of complementary colors to minimize a number of emissions of each of the plurality of primary color light sources and also displaying the video images of the colors of the plurality of primary colors and the plurality of complementary colors in sequence.

  • Publication number: 20080204845
    Abstract: A micromirror device comprises a plurality of mirrors arranged on a substrate, an elastic hinge for supporting each mirror to be deflectable, an address electrode having first and second regions arranged across the deflection axis of each mirror, a driving circuit for controlling a deflection of the mirror, and a stopper provided in a position of making contact with the mirror in a deflected state of the mirror. When the mirror makes contact with the stopper, the potential of the mirror or the stopper changes.
