Abstract
An organic light-emitting diode display apparatus includes a substrate. An organic light-emitting device is disposed on the substrate and includes a first electrode, a second electrode, and an emission layer disposed between the first electrode and the second electrode. A reflectance of the first electrode is greater than a reflectance of the second electrode. A thin-film transistor is disposed between the substrate and the first electrode and is connected to the first electrode. A first light reflective layer is connected to the thin-film transistor that is disposed between the substrate and the first electrode. A photo sensor is disposed in an outer area of the substrate and is configured to sense light reflected from the first light reflective layer.
