ABSTRACT:
There is provided a matrix-addressed driving method by which the image quality of a matrix type flat panel display device having bistability can be improved. Immediately after an application of an effective pulse of a selection signal, a counter-assist signal which has a polarity inverse to the polarity of the effective pulse of a selection signal for inverting the dark or bright state is added to the scanning signal. In lieu of this counter-assist signal or in addition to the counter-assist signal, an aid-assist signal having a polarity same as the polarity of the effective pulse of the selection signal may also be added at least one time before or after the application of the effective pulse.
