METHOD AND APPARATUS FOR DRIVING DISPLAY UNIT

摘要

The number of grey levels in LCD display devices is drastically increased by selecting the picture elements during a short part of the line period and by providing them with data signals. The column electrode is subsequently fixed at a reference voltage. The capacitive crosstalk thereby considerably decreases. If necessary crosstalk compensation can be used. This provides the possibility of introducing more grey levels. Simultaneously it is possible to take redundancy measures which would otherwise be impossible due to loss of grey levels.
