Patent ID: 10620504

Abstract:
Color-conversion structures for converting input pump light of a color to one or more differing colors. In some embodiments, the color-conversion structure includes a color-conversion (CC) layer having an input-side coating configured to optimize the amount of the pump light reaching the CC layer and to optimize the amount of color-converted light output by the CC layer. In some embodiments, the CC layer has an output-side coating configured to minimize the amount of unconverted pump light output from the CC layer and to maximize the color-converted light output from the CC layer. Various treatment for enhancing the performance of color-converting structures are also disclosed, as are a number of material combinations for quantum-well (QW) based CC layers and alternatives to QW-based CC layers. Also disclosed are light-emitting structures that each include a color-conversion structure made in accordance with the present disclosure, as well as displays composed of such light-emitting structures.
