Abstract
The present invention relates to an electrophoretic device where a viewing electrode, which is used to attract an electrophoretic medium to a viewing area, is divided into a first () and a second () sub-electrode which are separated on the viewing area. When the electrophoretic medium is to cover the viewing area, the electrophoretic medium is first collected at one of the sub-electrodes and is then spread over the viewing area by applying a pulse between the sub-electrodes.
