Claim 15:
16. A display device, comprising:
a display panel including a pixel connected between a first power line and a second power line, the pixel including a light emitting element connected between the first and second power lines and a driving transistor configured to control a driving current flowing through the light emitting element;
a power supply configured to apply power voltages to the first and second power lines of the display panel;
a current measurer configured to measure a current applied to the display panel from the power supply through the first and second power lines;
a sensing controller configured to output a first sensing control signal indicating whether to sense a threshold voltage of the driving transistor based on a measured current; and
a sensor configured to sense the threshold voltage of the driving transistor in response to the first sensing control signal,
wherein the sensing controller is configured to periodically: accumulate a value, of the measured current to generate a first accumulated current value and output the first sensing control signal in response to the first accumulated current value being greater than or equal to a first reference current value.
