Display techniques incorporating fluidic actuators and related systems and methods

A display device configured to alter an optical property by moving an amount of a first fluid through which external light can pass, the display device comprising:

• a fluidic display unit comprising at least a first cavity comprising a first fluid, the first fluid movable within the first cavity by varying an amount of pressure on the first cavity;
• and
• a fluidic actuator mechanically coupled to the fluid-filled cavity of the fluidic display unit, the fluidic actuator comprising a second fluid, a first cavity comprising the second fluid and bounded at least in part by a first elastomer, a second cavity comprising the second fluid and bounded at least in by part by a second elastomer, a channel connecting the first cavity to the second cavity and through which the second fluid can flow, and a valve configured to be electrically operated into an open state or a closed state and thereby allow or block a flow of the second fluid through the channel, wherein the fluidic actuator is configured to be electrically actuated to vary the amount of pressure on the first cavity of the fluidic display unit,
• wherein varying the pressure causes movement of the first fluid within the fluidic display unit, thereby altering the optical property of the display.
