Abstract
The thermally and electrically induced pleochroic dye switching effect in smectic A liquid crystal host is described. This phenomena provides inherent display memory, and thus can be mutiplexed virtually without limitation. LCDs utilizing this effect have good contrast and legibility. Actual devices made have demonstrated a writing rate in excess of 1000 characters per second, a contrast ratio of about 10 to 1, and a brightness above 35% of standard white. This paper includes a brief discussion on the electronic driving system and a unique thermal management technique designed to enhance the performance of the display.
