Abstract
A display driving apparatus includes a first bias circuit configured to provide a first bias current; a second bias circuit configured to provide a second bias current; a selection circuit configured to select and output the first bias current as a bias current during a first period in which a change in a driving current occurs, and select and output the second bias current as the bias current during a second period from after the first period to until a next change in the driving current occurs; and an output buffer configured to drive a first input current or a second input current by the bias current, and output the driving current for driving a panel, in correspondence to the first input current or the second input current.
