Abstract
The invention concerns an electrowetting device comprising first and second immiscible fluids, the liquids being sealed within a structure comprising a cap portion, a base portion, a gasket formed of a first material positioned between a first contact surface on said cap portion and a second contact surface on said base portion, and a first film formed of a second material between said gasket and one of said first contact surface and said second contact surface.
Claims22
An electrowetting device, comprising:
- first and second immiscible fluids defining an interface moveable by electrowetting, the liquids being sealed within a structure comprising:
- a cap portion;
- a base portion;
- a gasket formed of a first material positioned between a first contact surface on said cap portion and a second contact surface on said base portion;
- and
- a first film formed of a second material between said gasket and one of said first contact surface and said second contact surface.
A method of manufacturing an electrowetting device that contains first and second immiscible fluids, the method comprising:
- providing a cap portion having a first contact surface, a base portion having a second contact surface and a gasket formed of a first material having a first side for contact with said first contact surface and a second side for contact with said second surface;
- forming at least a first film of a second material on at least one of said first contact surface, said first side of said gasket, said second contact surface, and said second side of said gasket;
- positioning said gasket between said cap portion and said base portion and positioning said first and second fluids between said base and cap portions;
- and
- applying an amount of pressure such that said gasket and said first film are compressed sufficiently to create a seal between said cap portion and said base portion for sealing said first and second fluids within.
A variable focus lens, comprising:
- first and second immiscible fluids having different refractive indices, defining a light-focusing interface moveable by electrowetting, the liquids being sealed within a structure comprising:
- a cap portion;
- a base portion;
- a gasket formed of a first material positioned between a first contact surface on said cap portion and a second contact surface on said base portion;
- a first film formed of a second material between said gasket and one of said first contact surface and said second contact surface.
An optical diaphragm, comprising:
- first and second immiscible fluids, defining an interface moveable by electrowetting, the liquids being sealed within a structure comprising:
- a cap portion;
- a base portion;
- a gasket formed of a first material positioned between a first contact surface on said cap portion and a second contact surface on said base portion;
- and
- a first film formed of a second material between said gasket and one of said first contact surface and said second contact surface.
