A revolutionary new smart window technology based on electrophoretic effect demonstrates unprecedented optical contrast transitioning from 0.2% to more than 70% transmittance while exhibiting fast switching performance. Adapted to already existing manufacturing display facilities, ELM (Electrophoretic Light Modulator) technology developed by eLstar Dynamics is highly scalable and based on known robust electrophoretic operation. ELM technology is exceptionally versatile and can be adapted to many product specifications and applications.
