Current sensor and display device including the same

A display device, comprising:

• a display panel which displays an image based on image data;
• a power supply which provides a driving voltage to the display panel through a power line;
• a current sensor which generates first current data including an average sensing current, a minimum sensing current, and a maximum sensing current of a first period based on sensing currents generated by sampling a current flowing through the power line at a sampling frequency, generates second current data including an average sensing current, a minimum sensing current, and a maximum sensing current of a second period shorter than the first period based on the sensing currents, and includes a first controller controlling the image data or the power supply based on the second current data;
• and
• a timing controller which communicates with the current sensor every frame period and includes a second controller controlling the image data or the power supply based on the first current data and the second current data.
