1. A display device comprising:
pixels that receive data voltages corresponding to output grayscales;
a sensing circuit that senses electrical states of the pixels to provide sensing information; and
a grayscale converter that generates the output grayscales with respect to the pixels based on input grayscales and the sensing information,
wherein the grayscale converter predicts a temperature of at least one of the pixels based on the sensing information, calculates a current control amount for the at least one of the pixels based on the predicted temperature and the input grayscales, and calculates the output grayscales for the at least one of the pixels based on the current control amount and the input grayscales.
