Researchers from BOE improve microLED light output by adopting a novel package scheme

Researchers from BOE reported on a new microLED package design, that improves light output from microLED displays. 

The new design combines a high-refractive-index transparent adhesive, a high-reflectivity white adhesive and a microlens array. This new design increases light output, and uses the sidewall emission to significantly improve the optical efficiency of microLED displays. In addition to the adhesives and MLA, the researchers adopted a patterned design of the black matrix (BM) cover plate to further reduce light loss and improves the contrast. The result is a highly efficient display with an improved image quality.
