Abstract
A display device is provided, which includes: a light emitting element; a storage capacitor; a driving transistor supplying driving current to the light emitting element to emit light; a first switching transistor applying a data voltage to the driving transistor and the storage capacitor in response to a first scanning signal, a light sensor sensing amount of light according to the light emission of the light emitting element and generates a sensing signal depending on the sensed light amount; and a signal controller determining luminance corresponding to the sensing signal, comparing the determined luminance and a target luminance corresponding to the data voltage, and modifies an image signal.
