1. A display device comprising:
a display panel including pixels configured to emit light based on a data voltage;
a current limiter configured to determine a scale factor by comparing a previous frame load with a predetermined threshold load, and generate compensated image data by applying the scale factor to current image data as input image data of a current frame to adjust the data voltage; and
a data driver configured to convert the compensated image data into the data voltage and provide the data voltage to the display panel.
