Abstract
LED devices emitting white light comprise a blue-emitting LED, green-emitting quantum dots (QDs) and red-emitting KSiF:Mn(KSF) phosphor. A backlight unit (BLU) for a liquid crystal display (LCD) comprises one or more blue-emitting LEDs and a polymer film containing green-emitting QDs and KSF phosphor. The QDs and/or KSF phosphor may be encapsulated in beads that provide protection from oxygen and/or moisture.
