| abstract |
An electrowetting module ( 20 ) comprises a fluid chamber ( 8 ) which contains a first fluid (A) and a second fluid (B), which are separated by an interface ( 14 ), and means to ( 16,17 ) exert a force on at least one of the fluids to change the position and/or shape of the interface. By providing at least one of the fluids with a compound having at least one aromatic, non-fused, residue, the performance of the module can be enhanced. For example the optical power of an electrowetting lens ( 30 ) can be increased. |
