Abstract
A display device can include a display panel configured to display an image; a fingerprint sensor disposed on a rear surface corresponding to an image display area of the display panel; one or more force sensors disposed at a periphery of the fingerprint sensor or on a rear surface of the fingerprint sensor; a fingerprint sensing processor configured to control the fingerprint sensor and the one or more force sensors, and in response to the one or more force sensors sensing a force transmitted through an upper side of the display panel, activate fingerprint sensing of the fingerprint sensor; and an application processor configured to control an application and transmit an image signal to the display panel to display an object at an area in the image display area corresponding to a position of the fingerprint sensor.
