ResumoA new mode of 0°–360° bistable twisted nematic (BTN) liquid crystal display is developed by using a parameter space method. This new mode possesses a large dΔn value that provides a possibility of using a 4.8–7 μm cell gap and a 6.5 V operating voltage for the new 0°–360° BTN cells. The high-contrast ratios above 80 within −80°–80° viewing-angle ranges are obtained experimentally in a horizontal direction, and the highest contrast ratio achieved is up to 250. In the contrast ratio, the experiment’s results concur with the simulation results.
