ABSTRACT:
A driver circuit for driving an electrochromic display device having switching elements connected between a power source and the electrodes of the electrochromic display device. The driver circuit includes a data controller which converts a display information signal to a signal indicating a state of non-display in response to a display erase signal applied to a control terminal. A drive signal generator is responsive to the signal from the data controller to produce a bleaching signal by which a display of the electrochromic display device is erased.
