  • Patent number: 8836681
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for reducing artifacts in an image generated by a display device. In one aspect, data is written to a display and a position of display elements is maintained based on the application of a bias voltage pattern. The bias voltage pattern includes alternating polarities along one dimension in a pattern having a first frequency spectrum, and alternating polarities along a second dimension in a pattern having a second frequency spectrum that is different than the first frequency spectrum. At least one of the first and second frequency spectrums may include a plurality of frequency components.

  • Patent number: 8816977
    Abstract: Electronic devices may be provided that contain flexible displays and internal components. An internal component may be positioned under the flexible display. The internal component may be an output device such as a speaker that transmits sound through the flexible display or an actuator that deforms the display in a way that is sensed by a user. The internal component may also be a microphone or pressure sensor that receives sound or pressure information through the flexible display. Structural components may be used to permanently or temporarily deform the flexible display to provide tactile feedback to a user of the device.

  • Patent number: 8797632
    Abstract: This disclosure provides systems, methods, and devices for actuating, charging and calibrating the charge on a movable electrode in electromechanical systems (EMS) devices. The electromechanical systems device can include a first electrode, a second electrode spaced apart from the first electrode by a gap, a complementary electrode, at least one electrical contact, and a movable third electrode disposed between the first electrode and the second electrode. In one implementation, a method of calibrating charge on the movable electrode of the EMS device includes electrically connecting a complementary electrode to the first electrode to form a compound electrode and applying a calibration voltage across the compound electrode and the second electrode to produce a uniform electric field in the gap. Under the electric field the third electrode moves towards the first electrode until it connects with the at least one electrical contact.

  • Patent number: 8791897
    Abstract: Charge balanced display data writing methods use write and hold cycles of opposite polarity during selected frame update periods. The transitions between voltages of opposite polarity are sufficiently brief that the display elements do not change state. A release cycle may be provided to reduce the chance that a given display element will become stuck in an actuated state.

  • Patent number: 8780039
    Abstract: An optical system is provided, for example for use with a display device, for varying the shape of a surface in which an image displayed by the display device is perceived. The optical system comprises first and second spaced-apart partial reflectors, at least one of which is switchable between a first non-flat shape and a second different shape, which may be flat or non-flat. The reflectors, together with polarisation optics, provide a light path such that light from the display is at least partially transmitted by the first reflector, partially reflected by the second reflector, partially reflected by the first reflector and partially transmitted by the second reflector. Light which does not follow the light path is prevented from leaving the optical system.

  • Patent number: 8736948
    Abstract: An electromechanical image display includes a box-structure of cups arranged in a row and column matrix. A non-rotatable axle for each column in the matrix passes through each of the cups in a column. The axle holds display elements which are rotatable on the axle. At least one electric-field-generating conducting plate in each cup is connected to an electrical source. A display element for each cup is a parallelepiped having six faces with a tunnel through the geometric centers of two of the six faces to permit its installation on the axle. The display element is an electret, or contains one or more electrets, that rotationally responds to the electric field of the electric-field-generating conducting plate.
