Abstract: A display driving device includes a timing controller configured to generate test data having a predetermined periodicity, and a source driver configured to drive source lines of a display panel using the test data, determine that a bit error has been generated when aperiodicity appears in the test data, and measure a bit error rate (BER) based on the bit error.
