  • Publication number: 20240178346
    Abstract: A micro light-emitting diode and a display panel are provided. The micro light-emitting diode includes a semiconductor epitaxial stacked layer including a first semiconductor layer, a second semiconductor layer and an active layer therebetween; a first electrode electrically connected to the first semiconductor layer, and a second electrode electrically connected to the second semiconductor layer. The second semiconductor layer includes an N-type gallium phosphide (GaP) window layer, and the N-type GaP window layer plays a role in current spreading. The problem of low luminous efficiency of the micro light-emitting diode at a low current density can be solved and the luminous efficiency of the micro light-emitting diode at a low current density can be improved.

  • Publication number: 20240170609
    Abstract: The disclosure relates to the field of semiconductor manufacturing technology, and in particular to a vertical-type light-emitting diode, which includes a substrate, a semiconductor stack layer and an insulation implant layer. The semiconductor stack layer is disposed on the substrate, and the semiconductor stack layer includes the first semiconductor layer, the light-emitting layer and the second semiconductor layer that are sequentially stacked on the substrate. The insulation implant layer is formed in the semiconductor stack layer to divide the semiconductor stack layer into at least two individual dies. By forming the insulation implant layer in the semiconductor stack layer, it is possible to achieve small spacing between dies and allow them to be insulated from each other without the need to create trenches or use PI adhesive. It is possible to ensure the photoelectric quality of the vertical-type light-emitting diodes and make the surface of the vertical-type light-emitting diodes flatter.

  • Publication number: 20240113257
    Abstract: The invention discloses a light-emitting diode and a light-emitting device. The light-emitting diode includes a semiconductor epitaxial stack having first and second surfaces opposite to each other and including a first-type semiconductor layer, an active layer, and a second-type semiconductor layer stacked in sequence in a direction from the first surface to the second surface. The active layer includes n periods of quantum well structure, and each period of quantum well structure includes a well layer and a barrier layer deposited sequentially. A first spacer layer is disposed between the first-type semiconductor layer and the active layer, and a ratio of a thickness (nm) of the first spacer layer to a current density (A/cm2) of the light-emitting diode ranges from 0 to 10. In the invention, the thickness of the first spacer layer is adjusted according to the current density of the light-emitting diode to improve the luminous efficiency of the light-emitting diode.
