Abstract:
1. A method for driving a liquid crystal display in which a liquid crystal cell is mounted at an intersection of each of a plurality of scanning electrodes placed at specified intervals in a row direction and each of a plurality of signal electrodes placed at specified intervals in a column direction, by sequentially feeding scanning signals to said plurality of said scanning electrodes and by sequentially feeding data signals to said plurality of said signal electrodes, said method comprising: displaying gray-scale color of a monochromatic color by reversing a data signal for every said signal electrode and by sequentially feeding said data signal having the reversed polarity to each of corresponding said signal electrodes, said reversing being relative to a common potential applied to one terminal of all said liquid crystal cells, said data signal comprising a waveform defined during four consecutive scanning periods, said data signal waveform comprising combinations of:
