Abstract

An exemplary embodiment of the present inventive concept provides a display device including: a display unit including a plurality of pixels disposed on a display area; a display controller configured to control the display unit; a sensor including a plurality of first sensing electrodes and a plurality of second sensing electrodes disposed in the display area; and a sensor controller configured to recognize a touch of a user inputted into the sensor in a touch sensing mode and to recognize a fingerprint of the user inputted into the sensor in a fingerprint sensing mode, wherein the sensor controller changes a mode to the fingerprint sensing mode when no touch is inputted for a predetermined time period in the touch sensing mode and changes the mode to the touch sensing mode when authorization on a fingerprint inputted into the sensor is succeeded in the fingerprint sensing mode.

Dependent claims

A display device comprising:

a first substrate;
pixels provided on the first substrate;
first sensing electrodes formed to extend in a first direction on the first substrate and arranged along a second direction;
and
second sensing electrodes formed to extend in a second direction on the first substrate and arranged along the first direction;
wherein mutual capacitance is formed at crossing points between the first sensing electrodes and the second sensing electrodes, and the crossing points respectively serve as sensing cells, and
wherein a resolution of the sensing cells is equal to a resolution of the pixels.
