1. A method of controlling a display driving apparatus configured to operate a display device that displays an image, the method comprising:
receiving a first image signal (RGB) from an external system;
converting the first image signal (RGB) into a second image signal (RGB′) in a format processable by a data driver;
outputting the second image signal (RGB′);
converting the second image signal (RGB′) into a source signal based on a data control signal generated by a timing controller;
converting heat energy generated by the data driver into a voltage;
calculating a temperature of the data driver based on the converted voltage; and
changing a resistance for impedance matching between the timing controller and the data driver based on the calculated temperature.
