Title: ELECTROWETTING ELEMENT WITH STABLE FLUID CONFIGURATIONS
Abstract:
Apparatus comprising an electrowetting element (1) with a first fluid (11) and a second fluid (12) immiscible with the first fluid. A support plate has a surface with a first surface portion (SP1) lying in a first plane and overlapping a first electrode (17), and a second surface portion (SP2) lying in a second plane different from the first plane. On receiving display effect data indicative of a requested display effect, the electrowetting element is switched to a state in which the first fluid contacts substantially all of the first surface portion and the second fluid contacts substantially all of the second surface portion, using a voltage with a voltage value which is within a range of a plurality of voltage values at which the electrowetting element is in the state.
