Abstract:
1. A driver for driving a liquid crystal display, comprising: an input terminal that inputs input data; an output terminal that outputs output data; a bi-directional common driver equipped with a first input/output terminal and a second input/output terminal, an input/output relationship of the first input/output terminal and the second input/output terminal being reversed in accordance with a shift direction controlled by a control signal; means for switching that is disposed between the input terminal and the first and the second input/output terminals of the bi-directional common driver and that selectively inputs the input data from the input terminal to one of the first input/output terminal and the second input/output terminal; and means for switching that is disposed between the output terminal and the first and the second input/output terminals of the bi-directional common driver and that selectively leads and outputs the output data to the output terminal, the output data being output from one of the first and the second input/output terminals and the input data being input to the other of the first and the second input/output terminals by the means for switching.
