Abstract
Optical apparatus for a display device. The optical apparatus comprises a cavity, and a first fluid () and a second fluid (), held within the cavity, which are immiscible with each other. The first and second fluids are separated from each other by a meniscus () having a peripheral edge (). The optical apparatus further comprises a fluid motion control system arranged to control movement of the first and second fluids within the cavity using electrostatic forces, and a first surface () and a second surface (). The first surface has a different wettability for the first fluid than for the second surface. The first and second surfaces are arranged in the cavity to determine, upon activation of the fluid motion control system, a motion of the fluids within the cavity which has a preferential initiation at a first part () of the peripheral edge.
