Abstract
An electrophoretic display device in which an colloidal suspension of pigment particles is contained between a pair of electrodes, and means are provided in the structure of the electrodes of the cell for the establishment of a voltage threshold for the transport of pigment particles. This threshold permits the changing of the spatial distribution of pigment particles in specifically defined regions of the display cell.
