    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 display layer disposed on a substrate. The display layer includes a light emitting elements. A sensor is disposed on the display layer. Sensing lines of the sensor are disposed outside touch electrodes of the sensor and are electrically connected to the touch electrodes. A gesture sensor electrode of the sensor is disposed outside the sensing lines. In a plan view, the gesture sensor electrode does not overlap a conductor which provide a constant voltage to the light emitting elements.
