<p>Disclosed is a single-chip twin light source light emitting device including a first epitaxial layer, a substrate, and a second epitaxial layer. The first epitaxial layer includes a first n-type semiconductor layer with a n-type conducting structure, a first light emitting layer with a multi-quantum well structure, and a first p-type semiconductor layer with a p-type conducting structure. The second epitaxial layer includes a second n-type semiconductor layer with a n-type conducting structure, a second light emitting layer with a multi-quantum well structure, and a second p-type semiconductor layer with a p-type conducting structure. Therefore, the light emitting device can emit one-color or two-color light by controlling the first epitaxial layer and the second epitaxial layer respectively.</p> |
