Abstract: A method for driving a display device is performed by the display device. The method includes: displaying a first image including user convenience information through a display panel; generating sensing data corresponding to a fingerprint sensing area by using a photoelectric sensor; and determining whether a sensed fingerprint corresponding to the sensing data is a fake fingerprint by comparing expected sensing light illuminance information based on the first image with sensed light illuminance information of the sensing data. The first image includes a first color pattern in the fingerprint sensing area of the display panel. A fake-determination image pattern includes the first color pattern and a second color pattern different from the first color pattern.

Abstract: A display device includes: a first sensor driver connected to a first sensor unit including a first-analog-front end, a first analog-to-digital converter, and a digital signal processor; and a second sensor driver connected to a second sensor unit including a second-analog-front end, and a second analog-to-digital converter. In a first mode, the first-analog-front end and the first analog-to-digital converter generate first sensing information for the first sensor unit, the second sensor driver does not operate, and the digital signal processor processes the first sensing information based on a first setting value for the first sensor unit. In a second mode, the first-analog-front end and the first analog-to-digital converter do not operate, the second-analog-front end and the second analog-to-digital converter generate second sensing information for the second sensor unit, and the digital signal processor processes the second sensing information based on a second setting value for the second sensor unit.
