Abstract:
A matrix display apparatus is provided for displaying an image in accordance with display data. The display matrix comprises a plurality of scanning electrodes and a plurality of signal electrodes arranged in a matrix. A first driving circuit applies a plurality of selection voltages to the scanning electrodes. The scanning electrodes are divided into groups of h scanning electrodes. A selection voltage is applied to each of the plurality of scanning electrodes selected from the plurality of selection voltages in accordance with the selection pattern data. The second driving circuit provides a plurality of signal voltages to the plurality of signal electrodes. The second driver circuit comprises a memory for storing the display data for at least one group of h scanning electrodes and a selecting circuit for selecting a signal voltage applied to each of the plurality of signal electrodes.
