Boundary artifact suppression in segmented liquid crystal modulators
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.
