Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A driving apparatus, comprising: 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 configured to apply a chopping signal corresponding to an offset direction of the first amplificatio…
