1. A timing controller suitable for receiving image data and a timing signal from a host system and outputting output data to a data driving circuit, comprising:
a scrambler configured to output scrambled image data by scrambling the image data;
a pattern detection unit configured to calculate a first unbalanced pattern count as a count of unbalanced patterns included in the image data and a second unbalanced pattern count as a count of unbalanced patterns included in the scrambled image data; and
an output data determination unit configured to determine output data by using the first unbalanced pattern count and the second unbalanced pattern count.
