Abstract: The present disclosure relates to a display device. The display device according to an exemplary embodiment includes a display area comprising a plurality of pixels, a peripheral area that is disposed outside the display area, and a wiring portion in the peripheral area. The wiring portion includes a plurality of signal lines that are adjacent to each other and are arranged along a first direction and each extends in a second direction that is different from the first direction. The plurality of signal lines are arranged in an order of average voltages of signals respectively transmitted by the plurality of signal lines during one frame.

Abstract: A display device includes a display unit displaying an image, a fingerprint sensing unit disposed on one surface of the display unit and including fingerprint sensing pixels to sense a fingerprint, and a readout circuit providing a selection signal to the fingerprint sensing unit to select a predetermined amount of fingerprint sensing pixels from the fingerprint sensing pixels as a sensing area and receiving a fingerprint sensing signal from the sensing area. The readout circuit accumulates the fingerprint sensing signal provided from the fingerprint sensing pixels in the sensing area during a test mode and calculates a compensation value based on a difference between the accumulated fingerprint sensing signal and a reference value.

Abstract: A display device may include a display panel that includes a first region and a second region. The display device may include a controller that may receive a first gamma value and a second gamma value, use the first gamma value or a third gamma value to generate first image data, use the first gamma value and the second gamma value to generate a fourth gamma value, and use the fourth gamma value to generate second image data. The display device may include a data driver that may use the first image data and the second image data to generate a first data voltage set and a second data voltage set. The first region may use the first data voltage set to display a first portion of an image. The second region may use the second data voltage set to display a second portion of the image.
