Abstract: A display device includes a display panel and a scan driving circuit. The display panel includes a plurality of pixels and a plurality of sensors. The scan driving circuit drives a plurality of scan lines. Pixels in a j-th row among the plurality of pixels are connected to a j-th scan line among the plurality of scan lines, in which j is a positive integer. Sensors, which correspond to the pixels in the j-th row, from among the plurality of sensors are connected to an a-th scan line among the plurality of scan lines, in which a is a positive integer different from j.

Abstract: A display device includes a display panel, a sensor controller, and a driving controller. The display panel includes a plurality of pixels, each of which includes a light emitter to emit light to display an image and a plurality of sensors. Each of the sensors includes a light detector to detect user information. The sensor controller is electrically connected with the sensors and is configured to provide a reset control signal to the plurality of sensors. The driving controller determines a first time point initiating when a user is able to attempt to input the user information, determines a second time point when the user information is actually input, and provides the sensor controller with an enable signal to activate the reset control signal after the first time point and deactivate the reset control signal after the second time point.

Abstract: A display device is disclosed that includes a display panel, a scan driver, a panel driving circuit, and a readout circuit. The display panel includes a pixel that includes a light emitting element and a sensor that includes a light sensing element. The scan driver outputs a scan signal for driving the pixel and the sensor in response to a scan control signal. The panel driving circuit outputs the scan control signal. The readout circuit generates switching signals based on the scan control signal and outputs a fingerprint sensing signal corresponding to a sensing signal received from the sensor in response to the switching signals.

Abstract: A display device includes a display panel that includes a pixel and a sensor. The pixel includes a pixel driving circuit and an emission element. The sensor includes a sensor driving circuit and a sensing element. The display device also includes a driving circuit that drives the display panel. The sensor selectively operates in a first mode in which a fingerprint is detected and in a second mode in which illumination is detected.
