Abstract
Display device based on layer break up or layer displacement comprises picture elements contg. a first fluid and at least second fluid immiscible with each other within a space between a first support plate and a second support plate. The first fluid is electroconductive or polar. The device contains means for creating at least different states, in which one of the fluids e.g oil in a first state adjoins at least a first support plate and in the second state the other fluid 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. [on SciFinder (R)]
