  • Patent number: 7436389
    Abstract: A method and system for controlling a color of light output by a diffractive light device (DLD device). The color is determined by a gap voltage applied to the DLD device. During each of a number of time frames, one of a number of control bits in a control word is sent to bit line logic corresponding to the DLD device. Each of the control bits represents a gap voltage level. The applied gap voltage is then adjusted to the gap voltage level represented by the one of the number of the control bits.

    Abstract: A spatial light modulator comprises an array of micromirror devices each of which has a reflective and deflectable mirror plates. The mirror plates are moved between an ON and OFF state during operation, wherein the OFF state is a state wherein the mirror plate is not parallel to the substrate on which the mirror plate is formed. The micromirror device may have an ON state stopper for limiting the rotation of the mirror plate at the ON state angle, but does not have an OFF state stopper. The non-zero OFF state is achieved by attaching the mirror plate to a deformable hinge held by a hinge support that is curved at the natural resting state.

  • Patent number: 7400438
    Abstract: A transition time is a time from a state where a movable portion has been rotationally displaced in the first direction and stopped to a state where driving portions apply the physical action forces to the movable portion to rotationally displace the movable portion in the second direction, which is different from the first direction, and the movable portion reaches a final displacement position. An elastic force value of the elastic supporting portion and the transition time have such a relationship that when the elastic force value of the elastic supporting portion is equal to a certain value, the transition time takes a local maximum value. The elastic force value of the elastic supporting portion is equal to or less than the certain value at which the transition time takes the local maximum value.

    Abstract: A two-dimensional image projection device using array of micromirror array lenses and a random scanning technique is invented. Using the random scanning technique, the light efficiency is nearly doubled than that of the prior art. The invention makes a brighter and less power consuming display device possible. Because each micromirror array lens of array of micromirror array lenses can scan whole image plane, a fast self diagnosis and correction technique can be introduced in displaying device. The Self diagnosis and correction technique makes display device to maintain image quality even a few tens percent of micromirrors do not work properly. Owing to the scanning characteristics of micromirror array lens, the image projection device can express the same number of pixels image with less number of micromirrors than the prior art. This also enables small sized two-dimensional image projector, which can be incorporated in portable electronic equipments.

  • Patent number: 7158278
    Abstract: Electromechanical shutter and display comprising a two-dimensional matrix of such shutters are proposed, in which the membrane under the force of electrostatic attraction moves from its original position parallel to the substrate plane into a final position normal to the substrate plane, thereby transferring the shutter, or display pixel, from its “off” state into its “on” state. To produce the “on” state, the electrostatic force is applied only to a narrow conductive strip placed on the side of the membrane and rotates the membrane around the torsion hinges attached to this strip. Two-and three-electrode shutter and pixel configurations are considered. Both versions provide a bi-stable membrane behavior, which implies that the voltage needed to transfer the membrane into the “on” state is larger than the voltage needed to maintain the membrane in this state. This feature of bi-stability allows realization of functions “pixel hold” and “pixel select” using a simple passive matrix architecture.

  • Patent number: 7038655
    Abstract: An electrophoretic display has a viewing surface, and includes an image pixel. The image pixel includes a first plurality of particles having a first mobility, and a second plurality of particles having a second mobility. At a first addressing voltage, the first mobility is greater than the second mobility. At a second addressing voltage, the second mobility is greater than the first mobility. At least one of the first and second mobilities is a variable function of voltage, i.e., a function of an applied electric field. Application of the first addressing voltage produces a first optical state, which is determined by a motion of the first plurality of particles. Application of the second addressing voltage produces a second optical state determined by a motion of the second plurality of particles.

  • Patent number: 7027030
    Abstract: A magnetic display has two non-magnetic substrates, at least one of which is transparent; and a microcapsule coating layer is applied between the non-magnetic substrates. The microcapsules contain and seal light-absorptive black magnetic fine particles and light-reflective non-magnetic fine particles dispersed in an oily dispersion liquid. An array layer is buried in a capsule wall of each of the microcapsules for enclosing the oily dispersion liquid that contains the light-absorptive black magnetic fine particles and light-reflective non-magnetic fine particles. The array layer includes flake-shaped particles with a multi-layered structure for converting the black color of a character or image formed on a display surface, which is a color inherently exhibited by the light-absorptive black magnetic fine particles, into a variety of interference colors.

  • Patent number: 7002548
    Abstract: A drive controller for controlling to change the orientation of a display surface of a display in accordance with the seating position of occupants aboard a vehicle. A display unit is rotatably mounted on a vehicle. A controller automatically rotates the display unit to a first position where the display surface is oriented toward a driver seat, when an occupant is seated solely in the driver seat. The controller rotates the display unit to a third position where the display surface is oriented toward a front passenger seat, when an occupant is seated solely in the front passenger seat. The controller rotates the display unit to a second position where the display surface is oriented toward the middle point between the driver seat and the front passenger seat, on detecting both of the occupants are seated respectively in the driver seat and the front passenger seat.
