Abstract
In a liquid crystal display, a crosstalk correction signal which is the same for all video or pixel input signals is provided either directly from the input signals or from the column signal. The input signals are combined with the correction signal and modulated onto carrier signals, then, e.g., may be coupled to the LCDs through a single-wire row or column connection. The correction signal can be derived from either the pixel input signals or the column signal.
