Abstract: A method of driving a display device including driving a display panel including a sensing area defined above a fingerprint sensor in an initial mode, driving the sensing area in a first color pattern and a second color pattern having a color different from a color of the first color pattern, sensing a fingerprint through the fingerprint sensor that receives a light reflected by the fingerprint when the fingerprint is adjacent to the sensing area, determining whether the sensed fingerprint is a duplicate fingerprint, and performing a user authentication mode when the sensed fingerprint is a normal fingerprint. The first color pattern has a light transmittance higher than a light transmittance of the second color pattern.
