| 20110310131 | APPARATUS AND METHOD TO ENHANCE LEGIBILITY OF IMAGES SHOWN ON A DISPLAY - A display system and method for improving legibility of images viewed on a passive display in a bright environment, including apparatus and method for increasing or maintaining the range of grey levels for the image as viewed on the display and decreasing the number of grey levels used in that range. | 12-22-2011 |
| 20110267382 | DUAL SOURCE BACKLIGHT UNIT FOR USE WITH A DISPLAY, A DISPLAY SYSTEM AND METHOD - A display system, method and backlight unit for use with a display. The backlight unit includes a first light source and a second light source, wherein the first light source and the second light source are controllable independently of each other. The sum of light produced by the light sources illuminates the display to achieve illumination brightness capability of a higher intensity capable single light source. Changes in spectral characteristics and/or brightness characteristics due to aging or the like may be compensated. The first light source may provide a base line illumination level for the display and the second light source may be modulated to dynamically increase contrast and/or contrast ratio characteristics of the image being shown on the display to a viewer. | 11-03-2011 |
| 20110241978 | OPTICAL DISPLAY SYSTEM AND METHOD, ACTIVE AND PASSIVE DITHERING USING BIREFRINGENCE, COLOR IMAGE SUPERPOSITIONING AND DISPLAY ENHANCEMENT WITH PHASE COORDINATED POLARIZATION SWITCHING - A display apparatus includes a passive display, a light source, and a video signal input, in operation in response to a video signal the passive display modulates light from the light source to provide an image, and the intensity of the light source is controlled by the video signal. | 10-06-2011 |
| 20080297434 | STEREOSCOPIC LIQUID CRYSTAL DISPLAY (LCD) WITH POLARIZATION METHOD - A display system for stereoscopic displaying of images includes a pair of wide viewing angle displays arranged at an angle to each other, each display providing respective images formed by plane polarized light. A beam combiner is located between the displays such that the beam combiner transmits light from one display and reflects light from the other display, whereby the transmitted and reflected light are provided via the beam combiner in substantially the same direction. One of the wide viewing angle displays has a substantially vertical polarization and the other of the wide viewing angle displays has a substantially horizontal polarization. The display system provides for stereoscopic display of high-resolution images with wide horizontal and vertical viewing angles. | 12-04-2008 |
| 20080198459 | CONJUGATE OPTICS PROJECTION DISPLAY SYSTEM AND METHOD HAVING IMPROVED RESOLUTION - A conjugate optics projection display system includes a beam splitter positioned for viewing an object through the beam splitter and a projector positioned to project an image through the beam splitter, where the projector has a focal plane distance. A retroreflector is optically coupled to the beam splitter and positioned at a distance from the projector, where the distance is less than the focal plane distance of the projector. The retroreflector may include retroreflective elements having a size effective to match or exceed optical resolution requirements of the display system. | 08-21-2008 |
