摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method and apparatus for selectively blurring parts of an image set according to differences in disparity between successive images. As a result, the one-dimensional ‘ringing’ edge artifacts, intrinsic to autostereoscopic displays, are hidden, thereby improving the perceived image quality of a multi-view autostereoscopic image. The method may involve detecting regions of disparity between adjacent views, and then blurring those regions by weighted local pixel averaging. The relationship between the blur radius and the disparity is preferentially non-linear to maintain sharpness of low disparity regions.
