Viewing angle control mode using nematic bistability.
As an approach using bistable nematic liquid crystals, we present a liquid crystal display with viewing angle control using two stable states, splay and 180 degrees-twist at pi cell, with three terminal electrode structures. The splay state is controlled by in-plane switching for a wide viewing angle (WVA), while the 180 degrees-twist state is operated by vertical switching for a narrow viewing angle (NVA). With this bistable mode, we fabricated viewing angle-controlled LCDs without additional optical components.
