Abstract
An electrowetting optical element, having a first electrode layer stack and a second electrode layer stack. Each layer stack has an electrode for applying a voltage to the electrodes for rearranging polar liquid relative to non-polar liquid. A containment space is formed between the first and second electrode layer stack. One or more cell walls extend between the electrode stacks for defining sides of the containment space forming cells. The electrowetting optical element further includes a retroreflective layer for reflecting incident light back through the element.
Claims16
An electrowetting display, wherein said electrowetting display comprises:
- an active display area;
- and
- a passive bezel for housing said active display area, wherein said passive bezel is manufactured from a material that allows transmission of light waves at least in the visible spectrum, and wherein said active display area comprises of one or more electrowetting optical elements, the one or more electrowetting optical elements comprising:
- a first electrode layer stack and a second electrode layer stack, each of said first and second electrode layer stack comprising a voltage application electrode for rearranging polar liquid relative to non-polar liquid,
- a containment space formed between said first and second electrode layer stack, and
- one or more cell walls extending between said first and second electrode stacks for defining sides of said containment space forming cells, said containment space at least containing the polar liquid and the non-polar liquid, the polar and non-polar liquids being immiscible with each other, and
- a retroreflective layer for reflecting incident light back through said element, and
- wherein said passive bezel comprises a retroreflective layer for reflecting incident light back through said passive bezel.
