1. A display device, comprising:
a display panel including pixels connected between a first power line and a second power line, each of the pixels including a light emitting element configured to emit light in response to a driving current flowing between the first and second power lines;
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 voltage-current characteristic of the light emitting element of at least one of the pixels based on a measured current; and
a sensor configured to sense the voltage-current characteristic of the light emitting element of the at least one pixel 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 and the first sensing control signal in response to the first accumulated current value being greater than or equal to a first reference current value.
