Abstract
A display apparatus has a plurality of display scanning lines and supplies image signals for a number of image scanning lines less than the number of the plurality of display scanning lines to display elements controlled by the plurality of display scanning lines. The apparatus includes: storage member for storing image signals corresponding to a number of image scanning lines less than the number of the plurality of display scanning lines at least by an amount corresponding to one image scanning line; control member for reading image signals for one image scanning line stored in the storage member N times (an integer of 1 or more); and driving member for supplying image signals read N times by the control member to display elements controlled by N display scanning lines. By changing the number N of times in which the image signals are read from the storage member within one vertical scanning period, the image is displayed on the entire display apparatus at each vertical scanning period even when the number of image scanning lines within one vertical scanning period is less than the number of display scanning lines of the display apparatus.
