Abstract
A liquid crystal display includes a pair of electrodes separated by the liquid crystal layer, with at least one of the electrodes fashioned of a background portion and N segmented portions. Each segment is selectively energizable with a first waveform, having the same frequency, but a different phase, relative to the waveform energizing the background areas of the same electrode. The remaining electrode is selectively driven by one of a multiplicity of phase-shifted waveforms of the same frequency, to facilitate the display of characters, symbols and other indicia in one of 2.sup.N+1 display states.
