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.

Abstract: A display device includes a degradation compensator, a controller, a data driver, and a display panel. The degradation compensator generates a first fitting function and a second fitting function based on image data, generates a compensation function through a harmonic mean of the first and second fitting functions, and generates a compensation value based on the compensation function. The controller receives the compensation value, and generates input image data to which the compensation value is applied. The data driver receives the input image data to which the compensation value is applied, and converts the input image data into a data voltage. The display panel includes pixels, in which each of the pixels includes a pixel circuit which receives the data voltage and a light-emitting element electrically connected to the pixel circuit.
