Also this old article where Etulipa is distinguished from Liquavista:

Etulipa says that its technology is based on 'second generation' electrowetting which is said to have two distinct advantages over the Liquavista approach. Etulipa told us that one of the problems with the Liquavista approach is that the base of the display has to be hydrophobic. Unfortunately, that means that it turns out to be difficult to manufacture the walls for each pixel on that kind of surface. Etulipa puts the electro-wetting cell walls on the opposite surface, typically an ITO covered glass surface. This allows usage of standard LCD processing steps to create the requested cell structures with very high yields.
