MICRO-LED WITH IMPROVED LIGHT EXTRACTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240282888 titled 'MICRO-LED WITH IMPROVED LIGHT EXTRACTION
The abstract describes a micro light-emitting diode (micro-LED) designed to enhance light extraction. The micro-LED has a lateral dimension less than 20 micrometers and includes a light-emitting layer, an output facet, an optical interface via a mirror parallel to the light-emitting layer, and a non-vertical sidewall forming an angle with respect to a normal of the light-emitting layer. The light-emitting layer emits light consisting of a first light in a trajectory that escapes the micro-LED through the output facet without reflecting off the optical interface, and a second light in a trajectory that reflects off the optical interface and the non-vertical sidewall before escaping through the output facet. Additional features may include cavity effects, light guiding, total internal reflection at low-index layers, mirrors, and micro-optics.
