Abstract (en)

A matrix driven display apparatus can be scanned with less scanning electrodes than originally required for the display section. This can be done without changing the arrangement of the display section and the drive IC of the display apparatus if the number of the scanning electrodes of the display panel exceeds the number of the selection electrodes. To accomplish this, the layout of the outputs for selection signal and scanning signal generated by the drive IC device is reversed so that the selection electrodes of the display panel are scanned while scanning electrodes are selected by the selection signal, thereby permitting scanning of the display with less electrodes. Accordingly, duty per scanning electrode is sufficiently large. <IMAGE>
