Abstract :
In this paper, we demonstrate a transmissive color display based on voltage-stretchable liquid crystal (LC) droplet. The gray scale is induced by stretching a dye-doped LC droplet from a small circular visible area to different extent through dielectrophoretic force. This polarization-insensitive liquid display shows a relatively low operating voltage, fast response, wide viewing angle and good contrast ratio. Both transmissive and reflective mode can be configured.
