Thermally addressed liquid-crystal display for dynamic and static figures

Liquid-crystal electrothermo-optic effects are studied with changing temperature of the liquid-crystal cell subjected to an applied field. A liquid crystal becomes opaque in a higher temperature region and transparent in a lower temperature region below the transition temperature from the mesophase to the isotropic phase. By this contrast, a thermally addressed display is demonstrated for dynamic figures. IT is also demonstrated that the display can be changeably used for dynamic or static figures.
