A coating of an encapsulated electrophoretic medium is formed on a substrate ( 106 ) by dispersing in a fluid ( 104 ) a plurality of electrophoretic capsules ( 102 ), contacting at least a portion of a substrate ( 106 ) with the fluid ( 104 ); and applying a potential difference between at least a part of the portion of the substrate ( 106 ) contacting the fluid ( 104 ) and a counter-electrode ( 110 ) in electrical contact with the fluid ( 104 ), thereby causing capsules ( 102 ) to be deposited upon at least part of the portion of the substrate ( 106 ) contacting the fluid ( 102 ). Patterned coatings of capsules containing different colors may be deposited in registration with electrodes using multiple capsule deposition steps. Alternatively, a patterned coating may be deposited upon a substrate containing a conductive layer by varying the conductivity of the conductive layer by radiation exposure or by coating portions of the conductive layer with an insulating layer, typically a photoresist.
