摘要： Disclosed is a display device which includes a display panel, a voltage generator, and a driving controller. The voltage generator generates a driving voltage and determines a voltage level of the driving voltage based on a voltage control signal. A current compensator calculates a load based on previous image data and outputs compensation image data with target luminance by compensating for current image data based on the load. The driving controller turns on the current compensator in a normal mode such that an image is displayed with the target luminance, and turns off the current compensator in a setting mode such that an image corresponding to the current image data is displayed with given reference luminance.

摘要： Disclosed is a display device including a display panel, a temperature calculator, and a data compensator. The display panel includes a plurality of pixels. Each of the pixels includes one of a first light emitting element, a second light emitting element, and a third light emitting element. The temperature calculator senses a block temperature for each of a plurality of block areas partitioned in the display panel and calculates temperature of each of the plurality of pixels based on the block temperature. The data compensator generates compensation image data by compensating for image data corresponding to each of the pixels depending on the temperature.
