Flüssigkristallanzeigevorrichtung

摘要

A clock sent from a clock generator is subjected to frequency division by a plurality of frequency dividers responsible for different fractions of an input frequency. A switch selects and outputs any of the outputs of the plurality of frequency dividers, and thus varies the frequency of the clock within one horizontal scanning period. The clock is used to sample a video signal, whereby an image to be displayed on a liquid-crystal panel can be compressed or stretched according to a position in the horizontal direction of a screen. Thus, it can be prevented to give a sense of incompatibility even when a video signal indicating an aspect ratio different from the aspect ratio of the screen is displayed.
