Abstract
A single polar driving method for a cholesteric liquid crystal display. The method comprises the steps of selecting the pixels by applying a first signal switching between a ground and a first level to the common line of the selected pixels, driving the selected pixels into a reflecting state by applying a second signal out of phase with the first signal and that switches between a second and third levels to the segment lines thereof, driving the selected pixels into a transparent state by applying a third signal in phase with the first signal and that switches between the second and third levels to the segment lines thereof, and deselecting the pixels by applying a fourth signal fixed at a fourth level to the common lines thereof.
