DUAL ANODE FLAT PANEL ELECTROPHORETIC DISPLAY APPARATUS

摘要

An electrophoretic display (10) has a grid cathode matrix arrangement consisting of a first plurality of parallel conductive lines (12) insulated from a second plurality of parallel conductive lines (14) transverse to said first plurality. Located with respect to the grid and cathode lines are first and second anode (16) structures (16, 18). The first anode (18) is remote from the second (16) with the second anode (16) overlying the grid lines (14) of the display and insulated therefrom. The second anode (16) is biased to implement typical HOLD and ERASE modes independent of the first anode.
