ABSTRACT:
A display device having plural scanning electrodes and plural information electrodes crossing the scanning electrodes. The scanning electrodes are scanned in a skipping manner during a first routine to refresh the display, scanned in a nonskipping manner during a second routine in response to a scroll display of a portion of the display, and scanned in a nonskipping manner during a third routine in response to a change in position of a pointing device. The first routine is executed before the second routine is executed and the third routine interrupts the second routine when the second and third routines occur simultaneously.
