Patent number: 8441422Abstract: 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.Type: GrantFiled: September 24, 2009Date of Patent: May 14, 2013Assignee: Apple Inc.Inventors: Adiel Abileah, Willem den Boer, Richard T. Tuenge, Terrance S. Larsson

Patent number: 7009663Abstract: 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.Type: GrantFiled: December 17, 2003Date of Patent: March 7, 2006Assignee: Planar Systems, Inc.Inventors: Adiel Abileah, Willem den Boer, Richard T.

Patent number: 6507156Abstract: 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.Type: GrantFiled: April 13, 2001Date of Patent: January 14, 2003Assignee: Planar Systems, Inc.Inventors: Brad Aitchison, Terrance S. Larsson, Tin Nguyen, Kelly Petlig, Steven F. Wald

The stack is disposed between the first and second electrode layers. The gray scale is provided by selecting a set of selected ones of the pixel electrodes with data signals during a first subframe time period of a frame. 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.Type: ApplicationFiled: April 13, 2001Publication date: October 3, 2002Inventors: Brad Aitchison, Terrance S.

Patent number: 6278423Abstract: 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.Type: GrantFiled: November 24, 1998Date of Patent: August 21, 2001Assignee: Planar Systems, IncInventors: Steven F.
