Abstract: A method for restoring deterioration data of a display device, includes: reading deterioration data from a first storage unit; determining whether the deterioration data is abnormal by comparing a first deterioration value of a first block with adjacent deterioration values of adjacent blocks adjacent to the first block; restoring the deterioration data based on a look-up table in which a luminance retention rate according to a degree of deterioration is set and sensing data provided from a sensing unit, when the deterioration data is determined to be abnormal; and generating second image data by compensating for first image data based on the restored deterioration data. The display device includes blocks each including a pixel, the blocks include the first and adjacent blocks, the deterioration data includes deterioration values each representing a degree of deterioration of each of the blocks, and the deterioration values include the first and adjacent deterioration values.
