Apparatus and a related method of controlling an electrowetting element of the apparatus. Display effect data is received which is indicative of a requested display effect for two electrowetting elements. Based on the display effect data, one of the electrowetting elements is switched to either: a state with a first fluid contacting substantially all of each of a first surface portion and a second surface portion of a support plate surface; or a state with the first fluid contacting part of the first surface portion and a second fluid contacting substantially all of the second surface portion and a second part of the first surface portion. The other electrowetting element is, based on the display effect data, switched to a state in which the first fluid contacts substantially all of a first surface portion and the second fluid contacts substantially all of a second surface portion. For each electrowetting element, the first surface portion lies in a different plane from the second surface portion.
