Abstract: A display device includes a plurality of pixels, a plurality of gate signal lines extending in a first direction and connected to the plurality of pixels, and a plurality of data signal lines extending in a second direction and connected to the plurality of pixels. The second direction crosses the first direction. The display device further includes a fingerprint sensor configured to detect fingerprint information, and a driver integrated circuit (IC) configured to transmit a plurality of scan signals to the pixels via the gate signal lines, transmit a plurality of data signals to the pixels via the data signal lines, receive the fingerprint information from the fingerprint sensor, and encrypt the received fingerprint information. The display device further includes an application processor configured to receive the encrypted fingerprint information from the driver IC.
