ABSTRACT:
A matrix liquid crystal display device includes a first substrate with a plurality of common electrodes disposed thereon. A second substrate includes a plurality of second segment electrodes disposed thereon. A liquid crystal is sandwiched between the two substrates. A power circuit generates a plurality of voltage waveforms. A segment electrode driver receives at least a portion of the plurality of voltage waveforms to produce a voltage segment waveform in response thereto which are applied to the segment electrodes. A common electrode driver receives at least a portion of the plurality of waveforms and produces a common voltage waveform in response thereto. The power circuit includes a voltage compensating circuit for determining a voltage change within the matrix liquid crystal display device and, based thereon, determining the amount of distortion in one of the segment voltage waveforms or the common voltage waveforms and generating a correction voltage which is added to the segment voltage waveform or common voltage waveform which exhibits the amount of distortion.
