1. A driving method of a display device, the method comprising:
driving a display panel, which includes a pixel and a fingerprint sensor and displays a static image and a dynamic image, at a first frequency; and
driving the display panel at a second frequency lower than the first frequency for a purpose of sensing a finger and reading a fingerprint of the finger through the fingerprint sensor,
wherein the driving of the display panel at the second frequency includes:
driving the display panel at a (2-1)-th frequency when the display panel senses the fingerprint and displays the dynamic image; and
driving the display panel at a (2-2)-th frequency different in value from the (2-1)-th frequency when the display panel senses the fingerprint and displays the static image.
