摘要： A display device for a vehicle may include a display panel configured to display an image and a touch sensor configured to sense a touch of a user and generate touch information about the touch. The touch sensor may be operated in a first mode or a second mode. The touch information may include first information about a fingerprint of the user, second information about a position of the touch, and third information about movement of the touch. When the touch of the user is sensed, the touch sensor may operate in the first mode and generate the first information. When the generation of the first information is completed, the touch sensor may operate in the second mode and generate the second information and the third information. The power and the ignition of the vehicle may be controlled using the touch information.
