Abstract: A display device includes: a display panel including a normal pixel in a display region and a test pixel in a peripheral region, a sensing line coupled to the test pixel, and a sensing circuit configured to sense a mobility characteristic of the test pixel by measuring a current at a source node of the test pixel through the sensing line. The source node of the test pixel is electrically separated from the sensing line in a data writing period of a frame period, and is electrically coupled to the sensing line in an emission period of the frame period.

Abstract: A data driver includes a digital to analog converter, a buffer and a buffer controller. The digital to analog converter is configured to receive a data signal having a digital type and to convert the data signal into a data voltage having an analog type. The buffer is configured to buffer the data voltage and to output the data voltage. The buffer controller is configured to determine a parameter of the buffer based on previous line data of the data signal and present line data of the data signal.
