  • Patent number: 7463398
    Abstract: Display device based on layer break up or layer displacement having at least two different states, in which one of the fluids (5) e.g oil in a first state adjoins at least a first support plate (3) and in the second state the other fluid (6) at least partly adjoins the first support plate. In one embodiment a picture element corresponds to a substantially closed space and in the first state the other fluid layer substantially completely adjoins both support plates and is divided in two sub-layers. This makes it possible on the one hand to use lower voltages to make displacement occur. On the other hand this opens the opportunity to color displays.
