Abstract
A display device, in accordance with the present invention includes a transparent substrate and an array of pixels formed on the substrate, each pixel comprises a transparent electrode and a deformable member electrically actuated between a first state and a second state, wherein in the first state a liquid including a dye is disposed in a gap between the transparent electrode and the deformable member and wherein in the second state the deformable member reduces the gap between the transparent electrode and the deformable member such that the liquid is substantially removed between the deformable layer and the transparent electrode in the area of contact. A plurality of switches are formed on the substrate for supplying control signals to the array of pixels to selectively actuate the deformable members of the pixels, wherein each switch comprises an actuating member movable between an active state and an inactive state, whereby in the active state any control signal supplied to the switch passes through the switch, and in the inactive state any control signal supplied to the switch is prevented from passing through the switch. Fabrication methods are also disclosed.
