MULTIPLEXIBLE LIQUID CRYSTAL DISPLAY |
摘要 |
<p>A liquid crystal display based on the bistability effect, wherein the distance between the support plates is smaller than 10 mu m and the total twist of the liquid crystal is between 180 DEG and 360 DEG , preferably about 270 DEG . Over the entire viewing area of the display, randomly distributed spacers are provided. Because of these measures, the range of the bistable action is so narrowed that the display can be driven with operating voltages outside this range, using conventional multiplexing techniques. A high degree of multiplexing with short switching times and excellent contrast is obtained. The range of viewing angles is very large and independent of the direction of illumination.</p> |
