ABSTRACT:
A driving system for matrix liquid crystal display in which the picture elements in adjacent rows and/or adjacent columns are applied with signals of opposite polarities. These polarities are reversed for every other field of a picture frame. Such a system reduces flicker and cross-talk. The system is implemented by interleaving the precharging and charging signals of adjacent picture elements.
