Abstract
The present exemplary embodiments relate to devices and methods of processing data obtained by sensing a characteristic parameter of a sub pixel. A controller which receives a first clock signal and sensing data output from a data driver generates a second clock signal having a same phase as the first clock signal and outputs image data that is compensated based on the sensing data in accordance with the generated second clock signal to the data driver. By doing this, the controller generates the second clock signal using a part of the first clock signal output from the data driver and transmits the image data so that a skew or signal distortion which may be generated at the time of transmitting/receiving data is suppressed to improve sensing and compensation precision and suppress an image abnormality due to the sensing and compensation failure.
