Abstract
A display device includes a display panel which displays an image, a panel driving block which provides a data signal to the display panel, and a temperature measuring part which measures a temperature of the display panel and provides a measurement temperature to the panel driving block. The panel driving block includes a first memory which stores a reference gamma voltage corresponding to a predetermined reference temperature, a temperature difference calculating part which calculates a temperature difference between the reference temperature and the measurement temperature, and a compensation part which generates a correction gamma voltage by correcting the reference gamma voltage based on the temperature difference between the reference temperature and the measurement temperature. The data signal is generated based on the correction gamma voltage and the image signal.
