Claim 16:
17. A method of manufacturing an active matrix electrowetting on dielectric (AM-EWoD) device, the method comprising:
coupling a substrate comprising a plurality of driving electrodes to a set of thin-film-transistors;
operatively coupling a controller to the set of thin-film-transistors, wherein the controller is configured to provide a driving voltage to at least a portion of the plurality of driving electrodes;
forming a dielectric layer covering the plurality of driving electrodes and the set of thin-film-transistors;
forming a spatially variable wettability layer covering the dielectric layer, wherein the spatially variable wettability layer has a hydrophobic region and a superhydrophobic region, and
a top hydrophobic layer covering a singular top electrode, wherein the top hydrophobic layer includes a second spatially variable wettability layer.
