Driver circuit for electrochromic display device

摘要

An electronic device equipped with an electrochromic display device adapted to provide a display of information, which comprises a logic circuit arranged to provide a serial data, and a driver circuit composed of a serial/parallel converter to convert the serial data into a parallel data and a plurality of driver means responsive to the parallel data to drive the corresponding segment electrodes of the electrochromic display device in coloring and bleaching directions. The driver circuit may further include a segment selection circuit to enable a selected one of the driver means corresponding to the segment whose display state is to be changed over.
