Abstract: A method of displaying an image on a display panel includes displaying an image of a grayscale value A, imaging the image of the grayscale value A with a camera, displaying an image of a grayscale value B, imaging the image of the grayscale value B with the camera, determining a compensation parameter P of the grayscale value A for each pixel in the display panel using the imaged data of the grayscale value A, determining a representative value Q of probability distribution of the compensation parameters of the grayscale value A from the image of the grayscale value A, determining a representative value R of probability distribution of compensation parameters of the grayscale value B from the image of the grayscale value B and compensating an input image data for each pixel using the value P, the value Q and the value R.

Abstract: A display device includes a display panel and an optical module disposed under the display panel. The display panel includes a first display region under which the optical module is disposed to overlap the first display region in a plan view, the first display region including transparent regions through which light for an operation of the optical module passes and first pixels having a first pixel structure and disposed between the transparent regions, a second display region in which second pixels having a second pixel structure are disposed, and a third display region disposed between the first display region and the second display region, third pixels having a third pixel structure being disposed in the third display region, only part of the third pixels being driven during a display operation.

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.
