Claim 0:
1. A display device comprising:
a display unit comprising a plurality of pixels;
a touch sensing unit disposed on the display unit and comprising a plurality of touch electrodes;
a fingerprint sensing unit disposed below the display unit and overlapping the touch sensing unit, and comprising a plurality of fingerprint sensors;
a touch driver configured to drive the touch sensing unit to sense a touch of a touch input member;
a fingerprint sensor driver configured to drive the fingerprint sensors to sense a fingerprint of a user in a first mode and configured to drive the fingerprint sensing unit in synchronization with the touch driver to sense a touch of the user in a second mode;
a main processor configured to perform a task based on sensing information of the fingerprint of the user received from the fingerprint sensor driver in the first mode and configured to simultaneously control the fingerprint sensor driver and the touch driver to perform a task based on sensing information of the touch input member received from the touch driver and sensing information of the touch of the user received from the fingerprint sensor driver in the second mode, wherein a touch input member and a user's finger may be simultaneously recognized; and
a display driver configured to drive the plurality of pixels based on information of the task performed by the main processor to display an image corresponding to the information of the task performed by the main processor, wherein:
the sensing information of the touch input member comprises coordinate information and identification information of the touch input member,
the sensing information of the touch of the user comprises coordinate information of the touch of the user, and
in the second mode, the main processor is configured to receive touch sensing data generated during a first fingerprint frame period of the fingerprint sensor driver to perform a task corresponding to the sensing information of the touch input member received from the touch driver and a task corresponding to the sensing information of the touch of the user received from the fingerprint sensor driver during a second fingerprint frame period immediately after the first fingerprint frame period.
