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.

Display device with display panel comprising force sensor and fingerprint sensor and method driving the display device

A method of driving a display device includes: sensing a touch signal from a plurality of touch electrodes in a touch panel, sensing a force signal from a force sensor, based on the sensed touch signal, determining whether or not the touch panel is in a submerged state, when the touch panel is determined to be in the submerged state, increasing sensing periods of the touch signal and the force signal, detecting a baseline variation of the force sensor, based on the detected baseline variation, changing a sensing reference value of the force sensor, based on the increasing the sensing periods, sensing the force signal equal to or greater to the changed sensing reference value through the force sensor, and when the force signal equal to or greater to the changed sensing reference value is sensed through the force sensor, decreasing the sensing periods.
