Abstract

A tetrode type electrophoretic display (10) includes local anode lines (32) disposed perpendicular to the grid lines (20) and having a tined configuration (33). In operation, the local anode (32) may be used to write and erase selected independent pixels by applying appropriate voltages (36) to the various electrodes (26, 28, 20, 18, 32) of the display in the proper sequence. The tetrode employed preferably includes an intermediate mesh (28) to permit maintaining displayed images after power removal.
