1. A display apparatus comprising:
- a matrix of electrodes including scanning electrodes and information electrodes;
driving means for scanning said matrix so as to apply a selected driving waveform comprising driving signals to selected ones of said scanning electrodes, and to apply data signals in synchronism with the driving signals to said information electrodes in parallel; and
control means for controlling said driving means so as to perform, in response to a graphic event to be displayed, either an entire frame scanning in which said matrix is fully rewritten or a partial rewritting scanning in which said matri is partially rewritten, wherein a driving waveform selected for said entire frame scanning is different from a driving waveform selected for said partial rewriting scanning.
