Abstract

A light emitting diode (LED) assembly with current injection enhancement from the periphery of the LED is disclosed. In one embodiment, the LED assembly includes an LED comprising a light emitting layer disposed between a first layer having a first conductivity type and a second layer having a second conductivity type. The LED assembly further includes a first electrode and a second electrode. The first electrode is formed on a surface of the first layer opposite the light emitting layer, and electrically coupled to the first layer. The first electrode substantially covers the surface of the first layer. The second electrode is formed at along a portion of the periphery of the LED, outside of a perimeter of the first electrode. The second electrode extends through the first layer and the light emitting layer to the second layer, and is electrically coupled to the second layer. In one embodiment, the LED assembly includes one or more second electrodes along the periphery of the LED. In one embodiment, the one or more second electrodes partially surround the first electrode. In another embodiment, the one or more second electrodes completely surround the first electrode. In yet a further embodiment, the one or more second electrodes extend inwards of the sidewall of the LED.
