Data controling circuit and flat panel display device

The present invention relates to a data control circuit. More specifically, the present invention is a flat plate comprising a data driver and a display is provided between the panel minimize the malfunction of the channel reduction structure pyeongpin display device for reducing the number of channels of the data driver, and a data control reducing the power consumption circuit, and this It relates to a display device. According to an embodiment of the invention, more than one data line is different from a voltage into the switching elements of the MUX driver operating in the structure reduces the number of channels to share a single channel flat panel display of the polarity same as the polarity of the data voltage by the control, there is an effect that by reducing the voltage swing width of the control signal can prevent malfunction and to improve the power consumption.
