  • Patent number: 8593491
    Abstract: With respect to liquid crystal display inversion schemes, a large change in voltage on a data line can affect the voltages on adjacent floating data lines due to capacitive coupling between data lines. The change in voltage on these floating data lines can be increased when the application of voltage to the data line occurs after a toggling operation of the Vcom, i.e., when a voltage applied to the Vcom changes the voltage on the Vcom from one polarity to an opposite polarity. Various embodiments of the present disclosure serve to eliminate or reduce the effects of Vcom voltage toggling on data line voltages by applying a voltage (e.g., a fixed voltage) to the data lines while the voltage on Vcom toggles.
