Abstract
A display device includes: a display panel including pixels, a power voltage generator for applying a power current to the display panel in a driving period; and a current sensor including a sensing resistor disposed between the display panel and the power voltage generator; a sensing current determiner for determining a sensing current; and a constant current generator for generating a constant current to the sensing resistor in a test period. The sensing current determiner determines a test sensing current based on a test sensing voltage applied to opposite electrodes of the sensing resistor in the test period and an initial sensing resistance, determines a first sensing resistance based on the test sensing current, the initial sensing resistance, and the constant current, and determines the sensing current based on a driving sensing voltage applied to the electrodes of the sensing resistor in the driving period and the first sensing resistance.
