Abstract
A display device includes a display panel including an active pixel and a reference pixel, a reference pixel measurer which applies a reference data voltage and a gate voltage to the reference pixel, calculates a first threshold voltage and a second threshold voltage based on a driving current of the reference pixel and calculates a difference between the first threshold voltage and the second threshold voltage, and a driving controller which controls the reference pixel measurer and outputs a data signal based on the difference.
