Abstract
A liquid crystal display and a dot inversion driving technique for that liquid crystal display. The liquid crystal display includes a liquid crystal display panel having liquid crystal cells defined by intersections of gate and data lines. Each liquid crystal cell includes a thin film transistor. Those thin film transistors are connected in a zigzag pattern to the gate lines. Pixel voltage signals are applied in a line inversion fashion to the liquid crystal cells such that the pixel voltage signal polarities (referenced to a common electrode) are inverted in every horizontal period. The common electrode can be an AC voltage that changes in each horizontal period.
