Walk into your local electronics store and the red color emitting from many of the displays will be GE phosphor technology. Since first being introduced into the display industry in 2014, the red-line emission of K2SiF6:Mn4+phosphor (PFS/KSF) centered at 631 nm has become the market leading wide color gamut solution for 4K UHD TVs, tablets, phones, monitors and laptops. KSF provides a cost effective, on-chip LED solution for wide color gamut displays that is a RoHS compliant, drop-in replacement in LCD BLUs without the need for barrier encapsulants to achieve excellent reliability. This presentation will discuss the technology that has enabled this success and the path forward around integration into future displays with higher color gamut and additional functionality (minileds, remote films, microleds) versus current HDR 4K/8K displays. An update on GE’s efforts around narrow-band green phosphor development will also be presented.
