Abstract: Provided are a combined fingerprint recognition touch sensor, an electronic apparatus including the same, and a fingerprint enrollment method to which the same is applied. The combined fingerprint recognition touch sensor includes parallel transmission lines extending in a touch sensing region, and a plurality of parallel reception lines extending in the touch sensing region to intersect the transmission lines. A signal transmitter includes a plurality of transmission groups so as to apply driving signals to the transmission lines. A storage is configured to store an enrolled fingerprint image to be compared with an enrolled fingerprint for fingerprint authentication. In the fingerprint enrollment mode, a fingerprint image of a finger is obtained through one touch operation by applying driving signals to transmission lines belonging to two or more transmission groups and reading a fingerprint image of a sensing zone including an initial touch region and a surrounding region.
