A display device includes a substrate, and unit pixels provided in the substrate, and including sub-pixels each having a light-emitting element emitting light, and photo-sensing pixels each having a light-receiving element outputting a sensing signal corresponding to the light. Each of the sub-pixels may include an emission area emitting the light, and each of the photo-sensing pixels may include a light-receiving area receiving the light. The emission area and the light-receiving area may be provided in the substrate to be spaced apart from each other. Each of the emission area and the light-receiving area may have a shape of a quadrangular plane.

A display device includes a display panel having a display area and a non-display area. The display panel includes a pixel disposed in the display area and including a light emitting element and a pixel driving circuit electrically connected with the light emitting element, a sensor disposed in the display area and including a photo sensing element and a sensor driving circuit electrically connected with the photo sensing element, a data line electrically connected with the pixel and extended along a first direction, a scan line electrically connected with the pixel and extended along a second direction intersecting the first direction, and a readout line including a first readout portion in the display area. The first readout portion is electrically connected with the sensor and extended along the second direction in the display area.

An electronic device includes a frame and a display stack. The frame defines a first part of an interior volume. The display stack includes a cover attached to the frame. The cover may define a second part of the interior volume. The display stack also includes an array of organic light-emitting diodes (OLEDs) including an array of emissive electroluminescent (EL) regions, and at least one organic photodetector (OPD) disposed between the cover and at least one emissive EL region in the array of emissive electroluminescent regions. The at least one emissive EL region emits light through the at least one OPD. In alternative embodiments, the OLEDs may be stacked on the OPDs, or the OLEDs and OPDs may be interspersed with each other instead of stacked.
