    Abstract: An overdrive device includes a training unit, an analysis unit and a Contrast adjustment unit. The training unit establishes a luminance difference look-up table (LUT) having an R2 number of luminance differences. Each of the R2 number of luminance differences represents a luminance difference between a measured display luminance value and a target luminance value of a display device when each of first and second viewing angle images correspond to any value of a grayscale range R. With respect to first and second viewing angle input image data, for pixel data therein corresponding to a same pixel position, the analysis unit looks up the luminance difference LUT to obtain a looked-up luminance difference, and accordingly calculates a luminance difference index. The contrast adjustment unit partially adjusts the grayscale of the second viewing angle image according to the luminance value index to obtain headroom for an overdrive operation.

  • Patent number: 7626581
    Abstract: Embodiments of an exemplary MEMS interferometric modulator comprise a movable layer and a fixed layer separated by an air gap. A driving scheme employs row/column actuation protocols which maintain voltages to the MEMS interferometric modulator that are above or below the voltage range necessary to place the MEMS interferometric modulator within a “hysteresis window” or “stability window.” Stable operation of the MEMS interferometric modulator is achieved by selecting mechanical design features that optimize the actuation and release times of the interferometric modulator. Some of the features affecting the release and actuation times include altering post spacing, altering internal stress or tension of the movable layer, altering the thickness or composition of the movable layer, altering the bulkiness of the tethers, perforating the movable layer and providing vias in the fixed layer.

    Abstract: The invention provides a projector a lighting optical system, a micro-lens array, a shutter array, a liquid crystal light valve, a projection optical system, and a modulation control portion. The modulation control portion can control the shutter array and the liquid crystal light valve in response to levels of gray-scale of colors specified by input image signals. When the gray-scale value is 1% or less, time-interval control is effected in such a manner that 1% of light is allowed to pass through by the shutter array, while a fine gray-scale expression is achieved by the liquid crystal light valve. Also, when the gray-scale value is 0%, light is shut out completely by the shutter. When configured in this manner, it is possible to improve the reproducibility at darker levels of gray-scale and the contrast characteristics. Accordingly, the display characteristics of an image from a liquid crystal projector can be improved.

  • 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: 6967641
    Abstract: An image display apparatus includes a light valve for controlling at least the intensity of light projected along an optical path from a light source through the light valve. The light valve has a plurality of light transmitting elements at least the translucency of each of which may be adjusted periodically such that the translucency of each element is substantially constant except during intervals within which the translucency is being adjusted. A shutter is provided to obstruct the light path through at least one of the light transmitting elements during intervals within which the translucency of the element is being adjusted.

  • Patent number: 6950089
    Abstract: In one aspect, the invention includes a fader controller comprised of a longitudinally extending track having a portion thereof extending over an image area of an electronic display, and a fader cap joined to the track for longitudinal sliding translation therealong. A plurality of permanent magnets are spaced along the track, and the fader cap includes at least one electromagnet. Conductive rails extend longitudinally on the track, and the fader cap includes contacts that electrically engage the conductive rails. The electromagnets are actuated to translate the fader cap distally or proximally along the track. In another aspect, the invention provides a magnetic arrangement for removably joining one or more controller device to a flat panel electronic display, whereby controllers such as switches, knobs, and faders (slide controllers) may be superposed on the display.

  • Patent number: 6724519
    Abstract: An electrophoretic display having a protective electrode that reduces the degradation of the display caused by mechanical or electrochemical action. The electrode can include a protective layer that reduces the mechanical or electrochemical damage to a transparent conductive electrode. The protective electrode can be a vapor permeable electrode that is a reticulated electrically conductive structure, such as a metal screen or wire mesh, or a reticulated structure coated or impregnated with a conductive material. The protective electrode can include a layer that protects the display media from physical abrasion or removal by mechanical action, while allowing the application of an electric field to cause the display to be addressed.

  • Patent number: 6639572
    Abstract: A low power, paper white, direct-view display includes an array of hinged micromirrors that are deflected between two states, a first state in which the micromirror covers a portion of the background and a second state in which the micromirror uncovers the background. In one particular configuration, a stability mechanism is incorporated in the display so that the micromirrors switch between stable states and remain in those stable states unless and until an actuating force is applied to the micromirrors that is sufficient to overcome an actuation threshold. The mechanics of the hinge, stiction due to Van der Waals forces or a combination of both can be used to provide bistability. Bistability allows power to be removed from the display between updates but requires active actuation between both states. The drive electronics are similar to those used in multiplexed LCDs.

  • Patent number: 6630943
    Abstract: An alternate display content controller provides a technique for controlling a video display separately from and in addition to the content displayed on the operating system display surface. Where the display is a computer monitor, the alternate display content controller interacts with the computer utility operating system and hardware drivers to control allocation of display space and create and control one or more parallel graphical user interfaces adjacent the operating system desktop. An alternate display content controller may be incorporated in either hardware or software. As software, an alternate display content controller may be an application running on the computer operating system, or may include an operating system kernel of varying complexity ranging from dependent on the utility operating system for hardware system services to a parallel system independent of the utility operating system and capable of supporting dedicated applications.
