    Abstract: A display device includes a display panel partitioned into pixel rows, and the display panel includes pixels and fingerprint sensors arranged on the pixel rows, a panel driver for driving the pixels, and a sensor driver for detecting a user fingerprint, based on a sensing signal from the fingerprint sensors. The fingerprint sensors may include first fingerprint sensors on an odd-numbered pixel row and second fingerprint sensors on an even-numbered pixel row, and an area of an anode electrode of a light receiving element in each of the first fingerprint sensors may be equal to an area of an anode electrode of a light receiving element included in each of the second fingerprint sensors.

    Abstract: A display device includes light transmitting areas including a first light transmitting area and light emitting areas around the light transmitting areas and including a first light emitting area disposed around the first light transmitting area, wherein the first light emitting area includes a first-first light emitting area adjacent to a first portion of each of the light transmitting areas, a first-second light emitting area adjacent to a second portion of each of the light transmitting areas, a first-third light emitting area adjacent to a third portion of each of the light transmitting areas, and a first-fourth light emitting area disposed adjacent to a fourth portion of each of the light transmitting areas. The first-first to first-fourth light emitting areas each include at least one of first to third light emitting portions to emit light of first to third colors, respectively.

    Abstract: A display device includes a first pixel emitting visible light, a second pixel emitting infrared light, and a photo sensor receiving light. The first pixel includes a first light emitting element, an emission control transistor forming a current movement path passing through the first light emitting element, and a first transistor controlling a first driving current flowing through the first light emitting element. The second pixel includes a second light emitting element, an eleventh transistor controlling a second driving current flowing through the second light emitting element, and a twelfth transistor electrically connected between a sensor data line and a gate electrode of the eleventh transistor. A gate electrode of the emission control transistor and a gate electrode of the twelfth transistor are electrically connected to each other.
