Classification: CPC G | IPC G

Claim 16:
17. 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 in response to a data signal;
a data driver configured to generate the data signal based on image data, provide the data signal to the pixel, and receive a sensing signal corresponding to characteristic information of the light emitting element;
a current measurer configured to measure a current applied to the display panel from a power supply through the first and second power lines;
an age calculator configured to calculate an age of the pixel based on the image data; and
a sensing controller configured to adjust a time cycle of sensing a characteristic of the light emitting element by the data driver based on the age,
Wherein the sensing controller is configured to output a first sensing control signal in response to a first accumulated current value, in which a value of the measured current is greater than or equal to a first reference current value.
