DISPLAY DEVICE AND DRIVING METHOD THEREOF
First Claim
1. A display device comprising:
- 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.

12. A driving method of a display device, comprising:
-
recognizing a touch of a user inputted into a sensor in a touch sensing mode; when no touch is inputted into the sensor for a predetermined time period in the touch sensing mode, changing a mode from the touch sensing mode to a fingerprint sensing mode; recognizing a fingerprint of the user inputted into the sensor in the fingerprint sensing mode; and authorizing the fingerprint inputted into the sensor in the fingerprint sensing mode and, when the authorization is succeeded, changing the mode to the touch sensing mode, wherein the sensor includes a plurality of first sensing electrodes and a plurality of second sensing electrodes disposed in a display area. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
