ABSTRACT:
The number of grey levels in LCD display devices is drastically increased by not selecting the picture elements during a part of the line period and by providing them with data signals of opposite polarity. The capacitive crosstalk thereby decreases considerably. This provides the possibility of introducing more grey levels by sub-division of the picture elements into a number of sub-sections providing an extra drive with extra column electrodes. Alternatively, omission of the extra drive enables a given redundancy which would otherwise be impossible due to loss of grey levels.
