ABSTRACT:
A plasma display apparatus is adapted to operate with more than one scanning frequency. The display of images is performed in a state where the luminance level is maintained constant even when a vertical scanning frequency of a video signal changes. A luminance of a whole display image is held constant by adjusting the number of times of the discharge light emission of a plasma display panel. This adjustment is performed in accordance with the vertical sync frequency of the video signal supplied.
