Abstract
A display device may include a driving controller to generate output image data, a data driver to generate data voltages, and a display panel to display an image, wherein the driving controller is configured to divide the display panel into blocks, calculate accumulated degradation data for the blocks based on the output image data, calculate lifetime data of the blocks based on the accumulated degradation data, compare a difference value between the lifetime data for a first block and the lifetime data for a second block with a threshold value, determine a block with larger lifetime data between the first and second blocks as a long lifetime block when the difference value is greater than or equal to the threshold value, generate forced degradation data to degrade the long lifetime block, and generate the output image data by applying the forced degradation data to the input image data.
