Abstract

We demonstrate a liquid crystal (LC) droplet whose surface profile could be deformed by a fringing field. In the voltage-off state, the LC droplet exhibits a pillared shape by touching both substrates. As the voltage increases, such a droplet could be stretched to a cone-like shape or thin film. For a 1.5mm aperture LC droplet, its occupied area could be expanded by similar to 4.3x at 6.5V(rms) mu m(-1). Upon removing the voltage, the droplet could fully recover to its original shape. The shape stretching and recovering time are dependent on the expanded area. With the support of silicon oil around the droplet, the device is stable and the gravity effect is negligible.
