Abstract
When an active matrix LCD is driven while using inversion per n rows (n.gtoreq.2), stripe effects occur. In the case of double line inversion this leads to stripes in the picture. This can be largely obviated by supplying a different selection voltage to at least the last row of the rows in a group of n rows.
