A single-segment drive scheme for an electronic paper display (EPD) is replaced by a multiplexed drive scheme that reduces the number of driver pins to the number of display segments per digit or alphanumeric character plus one input/output (I/O) line per digit or alphanumeric character. In accordance with the invention, a passive digit selection mechanism enables a multiplex display drive scheme when the EPD material used typically has a stable threshold combined with a small hysteresis. Typically, display operation is better the smaller the hysteresis and the more stable the threshold of the EPD material that is used. |
