Abstract
A display apparatus comprises an electrowetting picture element with a first support plate with a first support plate portion comprising a layer substantially non-transmissive for light and second support plate portion substantially non-absorbing for light. A display controller is configured to control a display effect of the electrowetting picture element between a dark and light display effect, and, responsive to input data corresponding to the dark display effect, output at least one signal to a driver corresponding to the dark display effect. The driver is configured to, responsive to the at least one signal output by the display controller, apply a first, non-zero, voltage to the electrowetting picture element to switch a first and a second fluid of the electrowetting picture element to a first configuration with the first fluid and the second fluid in contact with a first surface of the first support plate portion and the first fluid in contact with a second surface of the second support plate portion.
