Abstract: A display apparatus includes a substrate, a pixel arranged in a display area of the substrate and including a light-emitting diode configured to emit light in a first mode, and a photo sensor arranged in the display area of the substrate and configured to receive, in a second mode, light reflected from an external object and receive external light in a third mode. The first mode is triggered by a signal to display an image, the second mode is triggered by reflection from the external object, and the third mode is triggered by absence of the signal to display an image and reflection from the external object.
