Abstract
A light-modulating or display apparatus employs electrowetting effect to controllably modulate, directly or indirectly, the shape or location of one or more measures of liquid. In one embodiment, at least one measure of liquid obstructs the passage of at least some portion of light passing onto, through or reflected off said apparatus, and thereby controllably modulating the angle of distribution, amplitude or intensity of light emitted or reflected by or passing through said apparatus. In another embodiment, light is propagating within a media due to the phenomenon of Total Internal Reflection, and one or more properties of light escaping from within said media through one or more adjacent measures of liquid is controllably modulated due to said change of shape or location of the measures of liquid.
