Patent number: 8792070Abstract: A polarization plate is provided for use between a light source and a display panel, where the light source is configured to emit light having a plurality of planes of polarization and the display panel is configured to have a predetermined polarization axis. The plate includes a repolarization region and a prepolarization region. The repolarization region is configured to diffuse and to depolarize or rotate at least one plane of polarization of the light passing therethrough. The prepolarization region is disposed adjacent to and in contact with the repolarization region. The prepolarization region is configured to be substantially nonabsorbent, to allow passage of light having a plane of polarization that is substantially aligned with the predetermined polarization axis, and to prevent passage of light having a plane of polarization that is not substantially aligned with the predetermined polarization axis. In another embodiment, an interface is provided between the regions.Type: GrantFiled: March 21, 2007Date of Patent: July 29, 2014Assignee: Honeywell International Inc.Inventors: L. S.

Patent number: 8228358Abstract: Method and apparatus are provided for displaying an image to a viewer with reduced visual artifacts. The apparatus comprises a display panel for forming the image using an array of pixels with distributed active regions, and a viewing arrangement optically situated between the display panel and the viewer for transferring the image formed on the display panel to the viewer with limited angular pixel subtense. The distributed active regions of the pixels are desirably divided into at least two simultaneously switched portions at least partly separated by or surrounding a significant portion of the non-switchable region. First order spatial harmonics and associated artifacts are reduced by the distributed apertures and second order and higher harmonics are reduced by limiting the pixel subtense angle seen by the viewer. A significant reduction in visual artifacts arising from the periodic structure of the display panel is obtained.Type: GrantFiled: December 16, 2005Date of Patent: July 24, 2012Assignee: Honeywell International Inc.Inventors: Brent D. Larson, Elias S. Haim, Matthew B. Dubin

Patent number: 8208013Abstract: A display system and method for providing user adjustability of displayed three-dimensional images. The system simultaneously displays a left-eye perspective view of an image and a right-eye perspective view of the same image, at a separation distance, and allows for the selective control of the separation distance via, for example, a user interface. The system and method allows multiple users to use multiple pieces of display hardware and quickly return each piece of display hardware to a user's own individualized preferences and compatibilities. It additionally allows a user to vary the display properties, such as providing extra foreshortening or stretching along the depth axis, quickly and simply.Type: GrantFiled: March 23, 2007Date of Patent: June 26, 2012Assignee: Honeywell International Inc.Inventor: Brent D.
