Abstract
A display device includes a display panel including a pixel electrically connected to a feedback line, a sensor electrically connected to the feedback line, the sensor being configured to measure an impedance of the pixel in response to a first control signal, and to measure a driving current flowing through the pixel in response to a second control signal, and a timing controller configured to selectively generate the first control signal and the second control signal based on an aging time of the display panel.
