Method of driving a liquid crystal display by supplying selectable column voltages Gj(t) from a predetermined number of column voltages levels, selection signals to groups of mutually orthogonal p rows (p≧1) for the duration of a row selection time p×nfrc during a supcrframe nfrc to generate grey scales. The column voltage is calculated depending on the grey scales of the p pixels in a column and on the mutually orthogonal selection signals Fi for the corresponding group of rows. The row selection time is subdivided in npwm sub selection time. The grey scales are coded in grey scale tables having nfrc phases with npwm. The superframes grey scales are generated using phase mixing. The change in the column voltage level defines a transition. The column voltage has always less transitions per row selection time than the number npwm of sub selection time of the row selection time.
