Claim 0:
1. An active matrix electrowetting on dielectric (AM-EWoD) device, comprising:
a substrate comprising a plurality of driving electrodes coupled to a set of thin-film-transistors, and including a dielectric layer covering both the plurality of driving electrodes and the set of thin-film-transistors;
a controller operatively coupled to the set of thin-film-transistors and configured to provide a driving voltage to at least a portion of the plurality of driving electrodes, and
a spatially variable wettability layer covering the dielectric layer, wherein the spatially variable wettability layer has portions which are hydrophobic, and portions which are superhydrophobic, and
a top hydrophobic layer covering a singular top electrode, wherein the top hydrophobic layer includes a second spatially variable wettability layer.
