Patent ID: 8717265

Claim:
A method, comprising: inverting the polarity of each consecutive two-line pair of an LCD panel during a frame refresh, wherein the inverting comprises: driving a first line of a two-line pair of an LCD panel to a first common voltage via a first common line common to a first subset of a plurality of lines of the LCD panel; switching a second line of the two-line pair to a high impedance state during the driving via a second common line common to a second subset of the plurality of lines of the LCD panel; driving the second line of the two-line pair to a second common voltage via the second common line; and switching the first line of the two-line pair to a high impedance state via the first common line, and wherein inverting the polarity of every consecutive two line pair comprises switching each of a plurality of common electrodes of the LCD panel at a rate equal to one-half the total number of lines of the LCD panel multiplied by a refresh rate of the frame refresh.
