Abstract
Provided is a display driving circuit including a plurality of source channels configured to provide data voltages to a plurality of data lines of a display panel, respectively; a dummy channel on one side of at least one of the source channels; and control logic configured to control operations of the source channels and the dummy channel, wherein, when failure of a first source channel from among the source channels is determined, the control logic is further configured to provide data voltages to data lines corresponding to the first source channel and second source channels, respectively, which are between the first source channel and the dummy channel, by using the second source channels and the dummy channel.
