  • Driver circuit for electrochromic display device
    Patent number: 4096412
    Abstract: A driver circuit for an electrochromic display device having segment electrodes and a common electrode adapted to display information in response to a display information signal. The driver circuit comprises a storage means for generating first and second output signals delayed in phase from the display information signal. A bleaching signal generating means is responsive to the first output signal, and a coloration signal generating means is responsive to the second output signal. First and second switching means are coupled to receive a bleaching signal and a coloration signal, causing an electric current to flow each of the segment electrodes in directions to induce bleaching and coloration, respectively. An auxiliary signal is applied to the first and second switching means to cause a segment to remain in its previously activated state for an extended period of time.
