ELECTROWETTING DISPLAY DEVICE

摘要

An electrowetting display device comprising: a greyscale picture element layer (GL) comprising at least one first picture element having a first fluid (Fl) configurable to provide a greyscale display state; and a colour picture element layer (CL) comprising at least one second picture element having a second fluid (F2) configurable to provide a colour display state. Each of the at least one first picture element and the at least one second picture element has a display area (2) for providing a display effect thereover. The electrowetting display device further comprises a control system arranged to change a configuration of the first fluid and the second fluid by changing a voltage applied to at least one first electrode (9) associated with the at least one first picture element and at least one second electrode (9') associated with the at least one second picture element, respectively.
