Semiconductor light source and driving circuit thereof

Abstract

Provided are a semiconductor light source and a driver circuit thereof. The semiconductor light source includes an active layer, a first semiconductor layer, a second semiconductor layer, a first electrode, a second electrode, and a third electrode. The first semiconductor layer and the second semiconductor layer are located on two opposite sides of the active layer. The first electrode is in ohmic contact with the first semiconductor layer. The third electrode is in ohmic contact with the second semiconductor layer. A first dielectric layer is disposed between the first electrode and the second electrode. The first semiconductor layer is a p-type semiconductor layer, and the second semiconductor layer is an n-type semiconductor layer. Alternatively, the first semiconductor layer is an n-type semiconductor layer, and the second semiconductor layer is a p-type semiconductor layer.
