An electronic interface for converting an interlaced video signal (101) to a non-interlaced video signal suitable for an LCD flat panel (127). An analog interpolator scheme is used in which the information available in an incoming video scan line is delayed and sampled (129), and output signals are created by interpolation between the sampled input and actual and interpolated scan line signals (131). The output signals are then converted into an integrated, sequential non-interlaced output signal (125) having a frequency corresponding to the horizontal resolution of a scan line of the flat panel.

Interface électronique destinée à convertir un signal vidéo entrelacé (101) en un signal vidéo non entrelacé adapté à un écran plat (127) d'affichage à cristaux liquides. On utilise un plan d'interpolateur analogique dans lequel les informations disponibles dans une ligne de balayage vidéo entrante sont retardées et échantillonnées (129), et des signaux de sortie sont créés par interpolation entre l'entrée échantillonnée et des signaux (131) de ligne de balayage effectifs et interpolés. Les signaux de sortie sont ensuite convertis en un signal (125) de sortie intégré séquentiel non entrelacé ayant une fréquence correspondant à la résolution horizontale d'une ligne de balayage de l'écran plat.
