DATA DRIVER AND LIQUID CRYSTAL DISPLAY USING THEREOF

摘要

A data driver and an LCD(Liquid Crystal Display) device using the same are provided to prevent non-uniform charge sharing by uniformly sharing data lines connected to first and last channels of a data drive IC(Integrated Circuit). A data driver includes first and second output switches and charge sharing switches(CSW1-CSWn). The first output switches electrically switch between a first amplifier for supplying a positive gradation display voltage and a first data line for receiving the positive gradation display voltage in response to a control signal. The second output switches electrically switch between a second amplifier for supplying a negative gradation display voltage and a second data line for receiving the negative gradation display voltage in response to the control signal. The charge sharing switches electrically switch between the first and second data lines in response to the control signal.
