Abstract
A display device includes a display panel including a plurality of pixels that each include an organic light emitting diode and a driving element, the display panel being configured to display an image data on the pixels; a data driver configured to generate a data voltage corresponding to the image data; a compensation circuit configured to sense a driving current flowing through the pixels and to generate a compensation data voltage that compensates for a threshold voltage of the driving element based on the data voltage and the driving current; a scan driver configured to generate a first scan signal and a second scan signal provided to the pixels; and a timing controller configured to generate control signals that control the data driver and the scan driver.
