ABSTRACT:
A scanning apparatus for an electrophoretic matrix display panel, has a horizontal (X-line) electrode driving circuit to provide a selecting pulse, a vertical (Y-line) electrode driving circuit to provide a data pulse, and an information signal supply means. An electric field is imposed across cells of an electrophoretic suspension layer to change the optical reflective property of the cells in a predetermined sequence after a pause interval by the horizontal and vertical electrode driving circuits. This causes operation of the display panel without cross effect.
