ABSTRACT:
A display apparatus includes a display panel having pixels formed at each intersection of scanning electrodes and data electrodes, and a driver for driving the display panel so that a period of each pixel placed in a prescribed display state is determined within a frame period depending on given gradation data. The driver divides one frame period into a first plurality of equivalent blocks of which a second plurality, smaller in number than the first plurality, of mutually non-neighboring blocks are allotted to a partial rewriting for selecting scanning electrodes corresponding to pixels to change display states. The remaining blocks other than the second plurality of blocks are allotted to an entire picture scanning for selecting all the scanning electrodes. Each scanning electrode is subjected to a plurality of selections during the entire picture scanning and during the partial rewriting so as to allow display of an identical number of gradation levels both in the entire picture scanning and in the partial rewriting.
