Abstract: A display device includes a display panel, a driving controller, and a readout circuit. The display panel includes a first part and a second part. The first part includes a first pixel set. The second part includes a first sensor set. The driving controller controls the first pixel set to emit first light when controlling the first sensor set to receive second light. The first sensor set generates a sensing signal using the second light. The readout circuit is electrically connected to at least one of the driving controller and the first sensor set and receives the sensing signal. The display device calculates a dust concentration using the sensing signal.

Abstract: A display device includes: a sensor configured to detect a user's biometric information; a display panel including a substrate disposed on the sensor, a pixel defining layer disposed on the substrate, and a light emitting element disposed in an opening of the pixel defining layer, wherein the display panel has a transmission area that overlaps the sensor when viewed from a plane; and an optical layer comprising a hole that overlaps the transmission area.

Abstract: A display device comprising a display panel including a first non-folding area having a first emission area, a second non-folding area having a sensing area and a folding area that is disposed between the first non-folding area and the second non-folding area. A first light emitting diode is disposed in the first emission area and a second light emitting diode and a light receiving element are disposed in the sensing area. A processor obtains a biometric signal of a user by using the light receiving element and at least one of the first light emitting diode and the second light emitting diode. The processor generates biometric information based on the biometric signal. The processor detects the biometric signal when the display panel is folded so that the first non-folding area and the second non-folding areas are disposed to face each other.
