  • MICRO-LIGHT EMITTING DIODE WITH METAL SIDE MIRROR
    Publication number: 20170373228
    Abstract: Light emitting diodes and display systems are disclosed. In an embodiment a light emitting diode (150) includes a p-n diode (120) including a mesa structure (129) that protrudes from a base structure (131). A reflective metallization (130) laterally surrounds the mesa structure, which also includes a quantum well layer of the p-n diode.
