Abstract: A display device includes: display pixels in a display area of a display panel; light-sensing pixels alternately arranged with the display pixels in the display area; a display scan driver configured to sequentially provide display scan signals to the display pixels through display scan lines; a flicker detection circuit configured to detect an occurrence of flicker in the display area by using light-sensing signals received from the light-sensing pixels; a touch sensing circuit configured to detect a touch from a user and coordinate data of a location of the touch via touch electrodes of a touch sensor; and a main driving circuit configured to maintain or change a driving mode of the touch sensor in units of at least one frame based on a flicker detection result and a flicker degree analysis result from the flicker detection circuit.

Abstract: A display device includes: at least one fingerprint sensor configured to sense a fingerprint of a user corresponding to a first fingerprint sensing area of a display panel; an image generator configured to generate a target fingerprint image based on a sensing signal output from the at least one fingerprint sensor; an image analyzer configured to detect a defect in the target fingerprint image based on at least one first fingerprint image corresponding to the first fingerprint sensing area and at least one second fingerprint image corresponding to a second fingerprint sensing area spaced apart from the first fingerprint sensing area of the display panel; and an image corrector configured to correct the defect in the target fingerprint image.

Abstract: A display device including: a display panel configured to display an image; a sensor overlapping the display panel; and a processor connected to the sensor, and configured to sense input from an object, in response to a sensing signal provided from the sensor, wherein the processor obtains, in response to the sensing signal, offset data that corresponds to a case where there is no input, and senses the input by reflecting the offset data to the sensing signal, wherein the processor senses touch input from the object in a first mode, and senses proximity of the object in a second mode, and wherein the processor changes a rule related to obtaining the offset data in response to an event occurring in the second mode.
