| 20110002577 | Backside Reflection Optical Display - The disclosure generally involves an optical (perhaps flat panel) display utilizing backside reflection for time-multiplexed optical shuttering. One display comprises a side-illuminated light guide associated with conditions for total internal reflection. A first surface of the light guide is elastomeric. Disposed against this elastomeric surface is an active layer that selectively deforms the elastomeric surface in locations that can correspond to display pixels. This resulting change in the geometry of the elastomeric surface can be sufficient to defeat the conditions for total internal reflection. When appropriate, light is reflected by the particular deformation and is ejected from another surface of the light guide. In this case, each location that allows light to exit could represent an activated display pixel. In certain situations, color flat panel displays of varying sizes may further implement field sequential color and time-multiplexed optical shuttering. | 01-06-2011 |
| 20100085750 | CAVITY REFLECTOR LIGHT INJECTION FOR FLAT PANEL DISPLAYS - The present invention describes a light mixing waveguide including a transparent slab waveguide having a reflectorized edge, a pair of opposing side edges adjacent to the reflectorized edge, a light transfer edge opposite the reflectorized edge, and a plurality of cavities formed inside the slab waveguide, wherein at least one of the side edges is configured to receive light from one or more light sources so that the received light is totally-internally reflected from top and bottom surfaces of the transparent slab waveguide. Interaction of the received light, the cavities, and the reflectorized edge mixes the received light prior to the light passing through the light transfer edge and into a target optical system. | 04-08-2010 |
| 20100073568 | Field Sequential Color Encoding For Displays - The optical performance is enhanced of display systems that use field sequential color and pulse width modulation to generate color and color gray scale values. Such enhancement may be achieved by various data encoding methods disclosed herein that may include temporal redistribution of bit values to mitigate color motional artifacts associated with field sequential color-based display systems, selective combination of intensity modulation, pulse width modulation, and/or the noncontiguous sequencing of primary colors. There is further an intelligent real-time dynamic manipulation of gray scale values in portions of an image that are computationally determined to be images of objects moving against a global background, so as to temporally front load or concentrate the bits comprising such moving objects and thereby further mitigate said motional artifacts using both actual and virtual aggregate pulse truncation across all primary colors being modulated. | 03-25-2010 |
| 20090262129 | EXTENDING THE GAMUT COLOR GENERATION IN A DISPLAY - In a display system, a color gamut of the displayed images is extended by adding one or more primary colors lying outside a tristimulus color space triangle to a Red, Green, Blue (RGB) system, modulating light emitted by both light sources lying inside the tristimulus color space triangle and light sources lying outside the tristimulus color space triangle, and adding a non-tristimulus vertex to construct an extended-gamut polygon. The display system adds one or more primary colors to the RGB system, which lie outside the tristimulus color space triangle but within a CIE (International Commission on Illumination) color space. | 10-22-2009 |
| 20090142020 | OPTICAL MICROSTRUCTURES FOR LIGHT EXTRACTION AND CONTROL - The application of optical micro structures improve the quality of light available to the viewer of an optical display system, or any display which works on the concept of moving one surface into direct contact or close proximity of a light guide to extract light through frustrated total internal reflection. Certain ones of the microstructures can act to assist in overcoming suction between the surface and the light guide. | 06-04-2009 |

| 20080290278 | VISIBLE PLUS NON-VISIBLE FIELD SEQUENTIAL COLOR - A circuit for implementing a registration-free, contiguous conductive plane. A circuit may include a plurality of conductive structures in a first plane. The circuit may further include a contiguous conductive equipotential surface in a second plane parallel to the first plane. The circuit may further include activation means configured to adjust an electric field between the first and second planes thereby activating one or more structures in the first plane by increasing a potential difference between the first and second planes to a threshold level deemed to constitute an active state. The circuit may further include deactivation means configured to adjust the electric field between the first and second planes thereby deactivating one or more structures in the first plane by decreasing the potential difference between the first and second planes below a threshold level deemed to constitute a deactivated state. | 11-27-2008 |
