Abstract
A display element having circuitry adapted to at least partially electrochemically dissolve a first layer by means of supplying an electrical current through the first layer. The first layer separates a first reservoir filled with a liquid from a second reservoir. By dissolving the first layer at least partially, at least a portion of the liquid can flow from the first to the second reservoir. Consequently, the display element transitions from a first to a second optical state.
