Abstract
A video display apparatus with a plurality of display devices arrayed in a line with a predetermined interval at portions which may be watched by passengers on a moving vehicle, a video signal supplying device for supplying a still picture video signal to the plurality of display devices, and an intermittent display control dence for energizing the plurality of display devices simultaneously and controlling a still picture video signal display time and a video display stop time at such an interval as to obtain a clear picture. A video signal which represents successive motions on the whole of a picture as seen from a moving vehicle is supplied to respective display devices. Since a picture is given by an electrical signal, it is sufficient that the contents of the picture may be changed by rewriting the contents of a video memory. Therefore, any pictures may be displayed, and a plurality of pictures may also be displayed. Moreover, a memory device stores a still picture video signal comprising a plurality of programs having contents different from each other. The programs are sequentially selected under control of a control unit, and a still picture video signal corresponding to a selected program is supplied to the display device. Thus, a plurality of pictures whose displayed contents are different from each other may be switched and displayed each time a train, for example, passes the display device.
