Abstract: A display device includes a data line, a pixel electrically connected to the data line, a data driver for outputting a data voltage, and a transmitter electrically connected between an output terminal of the data driver and the data line. The transmitter may transmit an instance of the data voltage to the data line in a first period. The transmitter may amplify a second instance of the data voltage to generate a reference voltage and then transmit the reference voltage to the data line in a second period different from the first period. The pixel includes a light emitting element for emitting light in response to the first instance of the data voltage. A voltage level of the reference voltage may be higher than a voltage level of the data voltage.

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.
