Abstract
The present invention relates to the use of a bromine anion in the conductive fluid of an optical electrowetting device, especially a variable focus optical lens driven by electrowetting. The invention also pertains to a multi-phase liquid composition comprising a bromine anion, as well as an optical lens driven by electrowetting comprising the same.
Claims26
A method of making an optical electrowetting device, comprising incorporating into an electrowetting structure a conductive fluid comprising a bromine anion.
A composition comprising water, a bromine anion and a freezing-point lowering agent.
A multi-phase liquid composition comprising a conductive fluid and a non-conductive fluid that is immiscible in the conductive fluid, wherein the conductive fluid comprises a bromine salt.
An optical electrowetting device comprising a conductive fluid and a non-conductive fluid that is immiscible in the conductive fluid, wherein the conductive fluid comprises a bromine anion.
