Electrowetting cells with high transmissivity fluids

A lighting device comprising:

• a light source;
• and
• an electrowetting cell coupled to the light source;
• wherein the electrowetting cell comprises a conductive fluid and a non-conductive fluid having refractive indices that differ by at least 0.2;
• and
• wherein the non-conductive fluid is selected from a compound of Formula 1, Formula 2, or Formula 3:
• wherein:
• R1, R2, and R3 are independently selected from H, a saturated or unsaturated, branched or linear C1 to C6 alkyl group, and a phenyl group;
• R is an aromatic group optionally substituted by one or more heteroatoms selected from N, O, and Si, wherein in Formula 1, R1 and R are optionally linked to one another so as to define a ring;
• wherein:
• R4, R5, R6, R7, R8, and R9 are independently selected from H, a saturated or unsaturated, branched or linear C1 to C6 alkyl group, and a phenyl group;
• R10 is an aromatic group optionally substituted by one or more heteroatoms selected from N, O, and Si;
• and
• wherein:
• R11, R12, R13, R14, R15, and R16 are independently selected from H, a C1 to C6 alkyl group, and a phenyl group;
• and
• n is an integer from 1 to 5, wherein when n is 2 to 5, each R11 and R13 group may be the same or different.
