Provided is a display device including a substrate including a fingerprint area. The fingerprint area includes a first area and a second area. A light-emitting element layer is disposed on the substrate. The light-emitting element layer includes light-emitting elements. A sensor layer is disposed on the substrate, the sensor layer including photosensors. The light-emitting elements include a first light-emitting element arranged in the first area and a second light-emitting element arranged in the second area. During a fingerprint sensing period, the first light-emitting element emits light and the second light-emitting element does not emit light.

Display device including a fingerprint sensor

A display device includes a display panel including a plurality of pixels configured to display an image, a photo sensor on one surface of the display panel to sense light, and a fingerprint detector configured to control a fake determination image pattern of a fingerprint sensing area of the display panel configured to sense a fingerprint, and to perform fingerprint authentication and fake fingerprint determination, based on a sensing signal supplied from the photo sensor.

Display device and method for driving the same

A display device includes: a substrate including a first region and a second region at one side of the first region; a plurality of pixels in the first region; a first gate line connected to a first pixel among the pixels; a second gate line connected to a second pixel among the pixels; a first capacitor in the second region; and a first selector configured to select one of the first gate line and the second gate line and connect the selected one to the first capacitor.

Display device

A liquid crystal display device includes a liquid crystal panel including a plurality of signal lines, a liquid crystal panel driving unit configured to provide a driving voltage to the plurality of signal lines, an image data judging unit configured to judge whether input image data is still image data or moving picture data, an image data correcting unit configured to correct moving picture data to output corrected moving picture to the liquid crystal panel driving unit, a plurality of light sources configured to provide a light to the liquid crystal panel, and a light source driving unit configured to detect a display region having a motion value larger than a reference value from among an image of which frame data is displayed, based on a comparison of current frame data of the moving picture data with previous frame data of the moving picture data.
