1. A light sensing system comprising:
a substrate;
a plurality of light-emitting devices disposed on the substrate;
a plurality of light-receiving devices disposed on the substrate; and
a plurality of light receiving-emitting unit devices, each of the plurality of light receiving-emitting unit devices comprising at least one of the plurality of light-emitting devices and at least one of the plurality of light-receiving devices,
wherein each of the plurality of light receiving-emitting unit devices comprises:
a light-emitting material layer which is formed on the substrate and comprises a light-emitting region comprising at least one light-emitting device and a non-emitting region,
wherein the non-emitting region comprises a same material as a material of the at least one light-emitting device, and
wherein at least one light-receiving device is formed on the non-emitting region.
