Abstract
A multi-standard display device having a liquid crystal display screen has so far only been realized by using all kinds of interpolation techniques. To make the number of rows and columns of the display screen independent of the incoming video signal and yet provide the possibility of displaying the various television standards without any disturbing errors, the incoming video signal is applied to the display screen via a scan-conversion circuit. The scan-conversion circuit reads in the video information in a first direction and subsequently reads it out in a second direction perpendicular to the first direction, for example, with storage in a memory. The video information is subsequently applied in the second direction to the row driver of the display screen, which row driver applies the video information to the display screen per column and under the control of the column driver.
