  • Publication number: 20230420602
    Abstract: Several embodiments of semiconductor systems and associated methods of color corrections are disclosed herein. In one embodiment, a method for producing a light emitting diode (LED) includes forming an (LED) on a substrate, measuring a base emission characteristic of the formed LED, and selecting a phosphor based on the measured base emission characteristic of the formed LED such that a combined emission from the LED and the phosphor at least approximates white light. The method further includes introducing the selected phosphor onto the LED via, for example, inkjet printing.

  • Publication number: 20170104126
    Abstract: Various embodiments of light emitting devices with built-in chromaticity conversion and associated methods of manufacturing are described herein. In one embodiment, a method for manufacturing a light emitting device includes forming a first semiconductor material, an active region, and a second semiconductor material on a substrate material in sequence, the active region being configured to produce a first emission. A conversion material is then formed on the second semiconductor material. The conversion material has a crystalline structure and is configured to produce a second emission. The method further includes adjusting a characteristic of the conversion material such that a combination of the first and second emission has a chromaticity at least approximating a target chromaticity of the light emitting device.
