Abstract
A display device may include a pixel set, a timing controller, a data driver, and a scale factor provider. The pixel set that may include pixels. The pixels may be divided into pixel groups. The timing controller may calculate first load values corresponding to an image frame of input image data and may generate image data by scaling gradation values of the input image data using scale factors. The data driver may generate data signals corresponding to the image data and may supply the data signals to the pixel set. The scale factor provider may calculate the first load values and one or more second load values based on temperature data corresponding to a temperature of the pixel set and may generate the scale factors based on the one or more second load values and a common current value of a current received by the pixels.
