Abstract
Apparatus and methods for forming a composite electrophoretic display comprised of multiple, stacked electrophoretic displays are described. The individual electrophoretic displays that form the composite display may be driven separately using different driving signals. The electrical connections for the individual displays may be configured to minimize the impact of the electrical connections on the overall aesthetic of the composite display.
