Method for driving a liquid crystal display device

When a new image is written to a liquid crystal panel, row electrodes are scanned a-line-at-a-time in time periods Tp1, Tp2, selected row electrodes are set at a voltage Vr, and all column electrodes are set at -Vc. The portions of a liquid crystal at the selected row electrodes have a voltage of Vr...

More Information
Summary:When a new image is written to a liquid crystal panel, row electrodes are scanned a-line-at-a-time in time periods Tp1, Tp2, selected row electrodes are set at a voltage Vr, and all column electrodes are set at -Vc. The portions of a liquid crystal at the selected row electrodes have a voltage of Vr + Vc applied thereacross to bring the liquid crystal in the entire screen into a planar state. After the portions of the liquid crystal at all pixels have been brought into the planar state, new display is written by a-line-at-a-time scanning in time periods Td1, Td2.
