Method and system of driving data lines and liquid crystal display device using the same

摘要

A data line driving method for a liquid crystal display device that does not require a separate pre-charge circuit and is capable of reducing pre-charge time operates by charging data lines to a desired level in response to a control signal for sampling the data lines. In one aspect, such a data line driving method includes the steps of generating a control signal; mutually short-circuiting the data lines in response to the control signal; pre-charging data lines to a desired level; mutually open-circuiting the data lines in response to the control signal; and sequentially applying video signals to the data lines in response to the control signal. A liquid crystal display device operable according to such a method includes data driving means for generating a pre-charging signal having a desired level; means for generating a control signal; and switching means for commonly applying the pre-charging signal to the data lines in response to the control signal, to pre-charge the data lines.
