ABSTRACT:
A matrix type display device capable of receiving more than one video signal, which displays an image based on a first video signal with a smaller aspect ratio than an aspect ratio of a screen in width by inputting a second video signal in sync with a first video signal to at least a part of column drivers corresponding to a remaining portion on the screen where the image based on the first video signal is not displayed, so that the processing of the first and second video signals is started at the same time and carried out at the same timing. Consequently, the present matrix type display device can readily display a natural image based on an input video signal with a smaller aspect ratio than the that of the screen.
