DRIVER APPARATUS FOR OFFSET CANCEL, AND ITS AMPLIFIER APPARATUS FOR OFFSET CANCEL

摘要

PROBLEM TO BE SOLVED: To provide a driver apparatus for offset cancel, and an amplifier apparatus for offset cancel.;SOLUTION: The amplifier apparatus for offset cancel includes an offset cancel unit and an amplifier unit. The offset cancel unit determines the timing and the state of an output control signal based on the latch signal and polarity signal in a panel display device. The amplifier unit is connected to the offset cancel unit, changes over the output terminal signal and feedback route of the amplifier unit based on the control signal output by the offset cancel unit, and thereby canceling the offset of the amplifier apparatus.;COPYRIGHT: (C)2008,JPO&INPIT
