<p><P>PROBLEM TO BE SOLVED: To provide a data driver of which the size, the chip area, and the cost can be reduced without increasing power consumption of a system. <P>SOLUTION: The data driver includes two data processing circuits for providing positive and negative pixel voltages respectively according to first and second pixel data, and a multiplexer circuit including multiplexer units. Each multiplexer unit has first and second input terminals receiving the positive and negative pixel voltages respectively, and an output terminal coupled to a data line. A first switching device has first and second switches serially coupled between the first input and output terminals. A node between the first and second switches is selectively grounded via a third switch. A second switching device has fourth and fifth switches serially coupled between the second input and output terminals. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
