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.

A liquid crystal display, comprising:
- a liquid crystal display panel having liquid crystal cells defined between intersecting gate lines and data lines;
- thin film transistors connected in a zigzag pattern to the gate lines;
- a common electrode disposed adjacent the liquid crystal display panel;
- liquid crystal disposed between the common electrode disposed and the liquid crystal display panel;
- and
- a liquid crystal display panel driver for applying pixel voltage signals to the data lines, wherein the pixel voltage signals on each data line has the same polarity in a horizontal period.
A method of driving a liquid crystal display, comprising the steps of:
- combining pixel data in a current horizontal period with pixel data in a previous horizontal period to produce combined pixel data in every horizontal period;
- and
- applying the combined pixel data to liquid crystal cells that are connected together in a zigzag pattern.
