Abstract
A data driving circuit of a liquid crystal display for selectively switching and multiplexing voltages in accordance with a bit order of input data is disclosed. The data driver circuit includes: a voltage distributor that selects one of a first voltage and a second voltages as first output voltage in accordance with the most significant bit of input data including a plurality of n data bits, that multiplexes the first voltage and the second voltage to be output as one of more multiplexed output voltage is one of the first voltage and the second voltage selected in accordance with bits of the input data lower in significance than the most significant bit, and that outputs the first voltage as a final output voltage; and an output buffer that is driven by the first output voltage, the one or more multiplexed output voltages, and the final output voltage.
