Abstract
A method and apparatus for driving a display device having a liquid crystal, plasma or electroluminescence unit or the like, wherein: when a display device consisting of display elements having discrete fixed pixels and wobbling elements for wobbling a light beam emitted from the display elements is to be driven, the timing of sampling while scanning a first field and the timing of sampling while scanning a second field are shifted by a period of time &Dgr;t corresponding to the amount of pixel shift &Dgr;Lx resulting from the wobbling, and the display elements are applied with the shifted timings of sampling, with the result that a high resolution interlace display compatible with the NTSC system or the HD system is made possible. In display devices having a liquid crystal display unit, plasma display unit, and electroluminescence display unit, interlace display capable of effecting the NTSC color television system or the HDTV system with high resolution is made possible.
