Abstract:
A driving apparatus and a display driving system. The driving apparatus includes a first amplification unit receiving a first signal and outputting a driving signal of a positive polarity voltage with respect to a reference voltage, a second amplification unit receiving a second signal and outputting a driving signal of a negative polarity voltage with respect to the reference voltage, and a controller for determining a chopping signal applied to a chopping terminal of the second amplification unit such that an offset polarity of an output voltage of the first amplification unit and an offset polarity of an output voltage of the second amplification unit are the same.
