Nano structured LEDs

摘要

An embodiment relates to a nanowire-containing LED device with optical feedback comprising a substrate, a nanowire protruding from a first side the substrate, an active region to produce light, a optical sensor and a electronic circuit, wherein the optical sensor is configured to detect at least a first portion of the light produced in the active region, and the electronic circuit is configured to control an electrical parameter that controls a light output of the active region. Yet, another embodiment relates to an image display having the nanowire-containing LED device with optical feedback.

主权项

1. A device comprising a substrate, a nanowire protruding from a first side of the substrate, a light-emitting diode (LED) comprising a portion of the nanowire, an optical sensor in the substrate and surrounding the nanowire, and an electronic circuit, wherein the optical sensor is configured to detect at least a first portion of a light produced in the LED by recombination of electrons and holes in the LED, and the electronic circuit is configured to control a bias of the LED.
