Abstract
An electrophoretic display having a plurality of individual characters which are individually addressable for writing and erasing. The anode of the display has a plurality of character blocks which correspond to the character positions of the display. The character blocks are interconnected by a series of character column and row control lines which are insulated from each other. Each character block is connected to one row line and one column line, respectively, by a resistor and a diode which are arranged in parallel. A further resistor is connected in series with the diode. An individual character block is erased by applying a negative voltage to the specific column line and row line which cross at the desired character block.
