ABSTRACT:
A display apparatus is constituted by a display device including a plurality of scanning lines, a plurality of data lines intersecting the scanning lines, and a pixel formed at each intersection of the scanning lines and data lines and showing plural display states depending on signals applied to an associated scanning line and an associated data line. The display device is driven by applying a selection signal to the scanning lines and applying to the data lines data signals for causing prescribed display states at the pixels in association with the selection signal. Further, at least one scanning line in a nonselected state is supplied with a dummy signal for temporarily changing display states of pixels on the at least one scanning line, whereby flickering on the display device is suppressed. The display apparatus is also applicable to gradational display.
