Abstract
Abstract Apparatus for displaying a video signal having a plurality of display elements corresponding to one standard of the television signal disposed in an X-Y matrix shape includes a separator (3) for separating a sync signal from an input video signal, a control signal generator (7) for generating a control signal in response to the sync signal, a driver (8) for driving the display elements of a display panel (12) in response to the video signal and the control signal, and a converter (13) for changing the number of scanning lines in response to a timing which changes in each picture or frame when another standard of the television signal is supplied as the input video signal.
