Abstract:
A display apparatus including a large-area fingerprint sensor includes a display panel displaying an image; a touch panel sensing a touch of a finger; a fingerprint sensor including a plurality of fingerprint pixels and recognizing a fingerprint of the finger; a fingerprint sensor driver driving the fingerprint sensor and including a driver driving the fingerprint sensor and a fingerprint recognizer recognizing a fingerprint by using sensing signals received from the fingerprint sensor; and a touch driver driving the touch panel, wherein the driver of the fingerprint sensor driver provides a sensing gate signal to sensing gate lines included in a first touch block determined being touched by touch position information received from the touch driver, among m (where m being an integer of 2 or greater) number of sensing gate lines included in the fingerprint sensor.
