  • Publication number: 20150116297
    Abstract: This disclosure provides systems, methods and apparatus for addressing an array of pixels in a display. In one aspect, an electromechanical device includes a movable element coupled between a first and second actuator, and a charge distribution circuit arranged to electronically couple the first actuator to the second actuator and capable of equalizing a potential between the first actuator and the second actuator. In certain implementation, a method for addressing an array of pixels in a display, where a given pixel in the array of pixels includes a light modulator coupled between first and second actuator capacitors, includes equalizing a potential between the first actuator capacitor and the second actuator capacitor prior to discharging and re-charging the actuator capacitors. Equalizing a potential may include transferring charge from one actuator capacitor to another actuator capacitor until the voltage across each actuator capacitor is approximately equal.

  • Patent number: 9019587
    Abstract: A display device provided with an MEMS light valve, comprising: a substrate, a fixed grating located on the substrate, an MEMS light valve for controlling the opening and closing of the fixed grating; a guide is disposed on the substrate. The MEMS light valve comprises: a movable grating, a movable electrode and fixed electrodes; the moveable grating is located in the guide and is electrically connected to the guide when contacting the guide; one end of the movable electrode is fixedly connected with the movable grating, and the other end is suspended; and the fixed electrodes and the movable electrode form a capacitor. When a potential difference forms between the fixed electrodes and the movable electrode, the movable electrode drives the movable grating to move in the guide, thereby opening and closing the fixed grating. Therefore, the MEMS light valve sensitivity can be enhanced and reliability is improved.

  • Publication number: 20150103387
    Abstract: This disclosure provides systems, methods, and apparatus for a MEMS display incorporating integrated sidewall reflectors. The display can include a light blocking component suspended over a substrate. The light blocking component can include an aperture in its surface that is parallel to the substrate. The display can include one or more sidewall reflectors positioned within the aperture. The one or more sidewall reflectors can be arranged at least partially normal to the surface of the light blocking component. Light that is directed through the aperture can be reflected off of the sidewall reflectors to escape from the display at a higher angle than would otherwise be possible.

  • Publication number: 20150091911
    Abstract: Systems, methods and methods of manufacture for, among other things, a MEMS device may be provided with a pair of electrodes that are separated by a gap. At least one of the electrodes is movable toward the other electrode. The MEMS device may include a beam that is positioned within the gap and arranged between the electrodes. As the movable electrode moves toward the other electrode, a portion of the MEMS device also moves towards, comes into contact with, and deflects the beam. As the beam deflects, it applies a force upon the MEMS device that opposes the movement of electrode toward the other electrode.

  • Patent number: 8995038
    Abstract: An optical time delay control device for controllably altering the transit time of an optical beam between two points. In one example, the device may include an optically transparent solid medium for receiving the optical beam, wherein at least a portion of the medium is generally a parallel piped shape characterized by a height, length and width, wherein the length is larger than the height; two mirrors affixed to two opposing parallel surfaces of the optically transparent solid medium, so that during operation the optical beam reflects between the two mirrors as the optical beam travels through the optically transparent medium; and an angle actuator for controllably altering the angle at which the optical beam enters into the optically transparent medium, thereby controllably altering the time that the optical beam travels through the device. This in effect permits control of the amount of delay of the transmission of light, and delays of 20 nanoseconds have been achieved.

  • Patent number: 8982441
    Abstract: An insulated glazing unit includes a spacer defining a framed area, first and second glazing panes attached to the spacer, a pane conductive layer on an inner surface of the first glazing pane, and a dielectric layer disposed on the pane conductive layer. A shade for use with the insulated glazing unit is affixed to the first glazing pane. The shade includes one or more layers selected from a resilient layer, a substantially transparent shade conductive layer, and an opaque shade conductive layer. When an electric drive is applied between the pane conductive layer and the shade conductive layer, a potential difference between the pane conductive layer and the shade conductive layer causes the shade to extend from a retracted configuration to an extended configuration. The shade can further include at least one ink coating layer including pigments that selectively reflect or absorb certain visible colors and infrared.
