Abstract: A polarization conversion system separates light from an unpolarized image source into a first state of polarization (SOP) and an orthogonal second SOP, and directs the polarized light on first and second light paths. The SOP of light on only one of the light paths is transformed to an orthogonal state such that both light paths have the same SOP. A polarization modulator temporally modulates the light on the first and second light paths to first and second output states of polarization. First and second projection lenses direct light on the first and second light paths toward a projection screen to form substantially overlapping polarization encoded images. The polarization modulator may be located before or after the projection lenses. The polarization-encoded images may be viewed using eyewear with appropriate polarization filters.

Abstract: Disclosed herein are systems and related methods for reducing speckle on display screen. More specifically, screen vibration is used to reduce speckle, and in accordance with the disclosed principles, the vibration may be achieved by using wave-based actuation (e.g., acoustic or electromagnetic waves) to vibrate the screen. In an exemplary embodiment, a speckle reducing system may comprise at least one actuating element located proximate to, but not in physical contact with, a display screen. In addition, the at least one actuating element may be configured to generate waves directed towards the display screen. When the waves impact the display screen, the waves impart vibration to the display screen.

Abstract: Disclosed herein are apparatuses and related methods for avoiding liquid crystal molecule twisting through local boundary orientation relevant to the alignment direction of liquid crystal structures. In one embodiment, a segmented polarization control panel may comprise a plurality of segment electrodes corresponding to a plurality of display segments of the sequentially scanning display. The plurality of segment electrodes comprise liquid crystals therein, and are arranged contiguously in a direction of the sequential scan. Electrode boundaries are created between adjacent segment electrodes, where each may be cascaded substantially parallel and perpendicular to a liquid crystal alignment direction of liquid crystals located within the segments. Preventing twisting by the disclosed techniques is particularly attractive in active retarder display systems employing fast striped pi-cell modulators.

Abstract: This disclosure primarily concerns 3D stereoscopic displays that provide alternately polarized left and right eye images encoded with a modulating LC polarization control panel (PCP) attached to the front of the display. Viewers then wear polarization analyzing eyewear to correctly see the different images. More specifically, the disclosure introduces global LC electrical reset during the addressing of liquid crystal time-sequential stereoscopic displays in order to reduce left/right eye contamination. LC materials in general do not respond fast enough with conventional addressing schemes to provide independent left and right eye images at the desired flicker-free, rate of sixty frames per second per eye. This disclosure and its embodiments may overcome this limitation, and also may address motion blur limitations, by driving pixels to a common LC state as part of the addressing cycle.

Abstract: A system and method for determining an intermediate stereoscopic representation, thus offering adjustable interaxial separation values, is presented. The design comprises obtaining a first image using a first image collecting device and substantially simultaneously obtaining a second image using a second image collecting device. The two recoding devices are physically separated by a distance, and the second image may be combined with the first image to form a stereoscopic image. The design further determines the intermediate stereoscopic representation based on aspects of the first image combined, typically algorithmically, with aspects of the second image.

Abstract: An improved drive scheme for a segmented polarizing modulator (or Polarization Control Panel) for use in an electronic stereoscopic display. The segmented polarization modulator segments are arranged contiguously in a direction of the sequential scan. The liquid crystal material used in each segment is driven in a manner to reduce the visibility of segment boundaries, by applying a positive or negative transition voltage (+T or −T volts) for a short period of time prior to applying +H and −H drive voltages. Optionally, the transition voltage may also be applied in transitioning from +H and −H drive voltages.

Abstract: A method and system for use in conjunction with a push-pull liquid crystal modulator system for creating circularly polarized light of alternating handedness is provided. The method and system comprise a pair of surface mode liquid crystal cells and a driver electrically coupled to the cells. The driver is configured to move an electrical charge using a quenching pulse comprising a relatively brief voltage spike at a beginning of a waveform period. Multiple additional improvements are provided, including reducing the thickness of the LC gap (the distance between cell electrode plates), creating a charge connection or wiring connection to the cell electrodes, employing anti-reflection coating technology, thinner ITO and ITO index matched to the LC material, bonding all possible air to material surfaces, using superior glass, employing more efficient polarizers, and reducing projector blanking time.
