Abstract:
A driving apparatus for applying predetermined voltages to a load, said apparatus comprising:a first signal line supplying a voltage at a first level to one terminal of said load, a second signal line supplying a voltage at a second level to said one terminal of said load, a third signal line supplying a voltage at a third level to another terminal of said load, and a fourth signal line supplying a voltage at a fourth level to said another terminal of said load, wherein the voltage of said second signal line is set at a fifth level and the voltage of said first signal line is set at said first level so that the voltage at said first level is supplied to said one terminal of said load through said first signal line, while the voltage of said third signal line is set at a sixth level and the voltage of said fourth signal line is set at said fourth level so that the voltage at said fourth level is supplied to said another terminal of said load through said fourth signal line, the voltage of said first signal line is set at said fifth level and the voltage of said second signal line is set at said second level so that the voltage at said second level is supplied to said one terminal of said load through said second signal line, while the voltage of said fourth signal line is set at said sixth level and the voltage of said third signal line is set at said third level so that the voltage at said third level is supplied to said another terminal of said load through said third signal line; and the fifth level is intermediate the first and second levels and the sixth level is intermediate the third and fourth levels.
