ABSTRACT:
A method for driving a matrix liquid crystal display device for displaying characters or a pattern is provided. A common voltage waveform is applied to at least one of a plurality of common electrodes at both ends of the common electrodes. A segment voltage waveform is applied to the segment electrodes. At least one of the segment voltage waveform and the common voltage waveform is varied to produce a display and remove non-uniformities on a liquid crystal display panel.
