1. A display driving circuit comprising:
a plurality of source channels configured to provide data voltages to a plurality of data lines of a display panel, respectively;
at least one 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 at least one dummy channel,
wherein, in response to failure of a first source channel from among the source channels being 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 at least one dummy channel, using the second source channels and the at least one dummy channel,
wherein the source channels are grouped into a plurality of source groups each comprising N (N is a positive number) source channels,
wherein the at least one dummy channel comprises a dummy group including N dummy channels.
