ABSTRACT:
A liquid crystal display device for displaying characters or a pattern without crosstalk interference includes a first substrate, a second substrate and a liquid crystal layer sandwiched therebetween. A plurality of common electrodes are formed on the first substrate and a plurality of segment electrodes are formed on the second substrate. A driver provides a common voltage waveform of either a selected or non-selected voltage to each of the plurality of common electrodes and provides a segment voltage waveform of either an ON voltage or an OFF voltage to the plurality of segment electrodes. A compensating circuit compensates at least one of the common voltage and the segmented voltage based upon the pattern of characters displayed by the liquid crystal display device.
