  • Patent number: 8570449
    Abstract: A system comprising a display having a stack of layers configured to display an image, multiple elements included in the stack of layers and a pressure sensor. Each of the multiple elements is configured to sense light. The pressure sensor is distinct from the multiple elements and is configured to sense a pressure applied to the display.

  • Patent number: 8441422
    Abstract: A system comprising a stack of layers configured to display an image and including multiple elements configured to sense light. The system is configured to obtain a first reference image based on output from the multiple elements in a dark lighting condition associated with the system, and calibrate object detection based on output from the multiple elements using the obtained reference image. Additionally, a system comprising a display having a stack of layers configured to display an image and including a first and second set of elements. Each of the elements in the first set is configured to sense light, and each of the elements in the second set is configured to sense a dark current. The system is configured to perform object detection based on output from the elements in the first set, and calibrate the object detection based on output from the elements in the second set.

  • Patent number: 7009663
    Abstract: A liquid crystal device including a front electrode layer, rear electrode layer, a liquid crystal material located between the front electrode layer and the rear electrode layer. A polarizer is located between the liquid crystal material and the front electrode layer and changing an electrical potential between the rear electrode layer and the front electrode layer modifies portions of the liquid crystal material to change the polarization of the light incident thereon. A plurality of light sensitive elements are located together with the rear electrode layer and a processor determines the position of at least one of the plurality of light sensitive elements that has been inhibited from sensing ambient light.

  • Patent number: 6507156
    Abstract: An active matrix electroluminescent device provides a gray scale display. The device comprises a first electrode layer including a plurality of individually addressable pixel electrodes, a second electrode layer, and a stack including at least a phosphor layer which produces light upon the application of an electric field across the phosphor layer and a dielectric layer. The stack is disposed between the first and second electrode layers. The second electrode layer is driven during the first subframe time period with a first illumination signal having a first amplitude. At least one of the set of the selected ones of the pixel electrodes is selected with data signals during a subsequent subframe time period of the frame.

  • Patent number: 6278423
    Abstract: The system illuminates an active matrix EL device (AMEL) to provide a gray scale display. The device includes a first electrode layer comprising an active matrix of individually addressable pixel electrodes, a second electrode layer, and a thin film EL laminate stack including at least an EL phosphor layer and a dielectric layer. The stack is disposed between the first and second electrode layers. A first group of selected ones of the pixel electrodes are addressed with data signals during a first subframe time period where the first group includes fewer than all of the pixels electrodes of the display. The second electrode layer is driven during the first subframe time period with a first illumination signal. A second group of selected ones of the pixel electrodes are addressed with data signals during a second subframe time period where the second group includes at least one pixel electrode not included within the first group.
