Abstract: A spatial light modulator having an active and a peripheral region, wherein coherent light impinges on both regions, but due to a higher spatial frequency of pixels within the peripheral region, and due to biasing the peripheral region pixels to maximize dispersion of reflected light therefrom, a majority of light reflected from the peripheral region is directed outside of a three-dimensional target window. A spatial frequency of the pixels in the active region is selected such that maximum dispersion of reflected light from the active region is incident within the three-dimensional target window. In this way, incident light that does not reflect from the active region need not be absorbed, or blocked, but instead can be reflected, but still fails to interfere with the target window.

Abstract: A direct view display provides a light modulating panel and a backlight including first and second sets of spectral emitters. Several modes of operation may be provided including an advanced 2D mode, and an enhanced color gamut mode employing simultaneous illumination of the first and second set of spectral emitters. Another embodiment may be an optical structure for a multi-functional LCD display with wide color gamut and high stereo contrast. The optical structure may also be used to produce more saturated colors for a wider display color gamut and also may be used to produce a brighter backlight structure through light recycling of the wider bandwidth light back into the optical structure.

Abstract: Systems, methods, and apparatus are disclosed for attenuating an incident polarized light beam using a plurality of Liquid Crystal Polarization Gratings (“LCPGs”) and one or more switchable liquid crystal layers. When four LCPGs are used, a spacing between first and second LCPGs can be equal to a spacing between third and fourth LCPGs. Pi and FCL cells can also be used in place of more traditional LC switches. Switching of the LC switch can be imparted via an AC bias.

Abstract: Optical systems having at least one polarization beam splitter (PBS) are operable to receive randomly-polarized light bundles from a projector lens. The PBS is further operable to direct light bundles having a state of polarization (SOP) along a light path and operable to direct other light bundles having a different SOP along different light paths. The light paths have optical path lengths which may differ. Each light path produces an image having a distortion which may differ from the distortion of an image produced by a different light path. A compensation in a light path is operable to convert a non-compensated distortion of an image into a compensated distortion that more closely matches the distortion of images in other light paths.

Abstract: The present disclosure includes systems and methods for solving speckle problems by exciting the screen with a more complex vibration spectrum. A range of frequencies provides, in effect, a collection of overlapping patterns of high and low displacement, so that all regions of the screen have enough motion to reduce visible speckle. As previously discussed acceptable speckle may be approximately 15% contrast or less, preferably approximately 5% contrast or less at approximately 15 feet from the screen.

Abstract: Liquid crystal devices may include electrode segments that are spaced apart and have a gap therebetween. A bridge layer may be disposed in the gap and configured to have a resistance that is operable provide a substantially equipotential region proximate to the gap portion while still allowing the electrode segments to be substantially isolated electrically. The disclosed liquid crystal devices may have reduced visual artifacts and may be configured to be a liquid crystal display, a polarization control panel, or a switch having liquid crystal cells.
