Abstract

A display includes an imaging device with a light source providing a first light emission and a second light emission, and an organic light-emitting diode panel proximate to the light source, wherein the first light emission leaks at an active area of the display device. A light emission barrier blocks the first light emission from leaking at the active area of the display while permitting the second light emission through the imaging device.
