Abstract
A printing surface includes a substrate having latching electrodes on a first surface, a spacer layer on the first surface of the substrate, the spacer layer patterned to form wells such that the latching electrodes reside in the wells, a deformable membrane, the membrane having conductive regions, on the spacer layer to enclose the wells, each enclosed well and its associated region of the membrane forming a pixel membrane, and actuation circuitry to actuate the electrodes to cause selected ones of the pixel membranes to remain in a deflected state when the pixel membranes receive an impulse to return to an undeflected state.
