Abstract:
A micro-electromechanical shutter assembly comprising:a transparent face plate layer provided to protect the shutter assembly from environmental effects;a first conductive layer located below the transparent face plate, patterned with vertical sidewalls which define a cavity;a second conductive layer located below the first conductive layer patterned in the shape of a shutter including shutter segments suspended by springs, the shutter formed near the bottom of the cavity;a spacer layer located below the second conductive layer;an electrically insulating bottom layer located below the spacer layer, whereby the spacer layer defines a gap between the second conductive layer and the bottom layer;a third conductive layer located on the electrically insulating bottom layer;an electrical terminal which provides a selectively actuated bias voltage to the sidewalls;first address signal lines in operative connection with the shutter assembly, to provide selectively actuated first address signals to the shutter assembly; andsecond address signal lines in operative connection with the third conductive layer to provide selective actuated second address signals to the third conductive layer.
