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