Abstract
A display and its driving method is provided in which the image signal can be input into a panel having a smaller number of rows than the number of scan lines for the image signal, without producing image distortion. For example, a signal of the system having more rows is displayed on a display for the NTSC having less rows. The signal control is made such that an image signal is written in two rows at every horizontal scan, except for a particular image signal, but the particular image signal is written in one row. Normally, the image signal for every horizontal scan is written in two rows, but only a particular image signal for every horizontal scan is compressed and displayed in one row. Accordingly, the vertical resolution is not degraded, unlike the scan for thinning out the image signal.
