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.
