SULFIDE PHOSPHOR, LIGHT EMITTING DEVICE PACKAGE, BACKLIGHT UNIT AND ITS MANUFACTURING METHOD

摘要

The present invention relates to a sulfide phosphor, a light emitting device package and a backlight unit and a manufacturing method thereof which are applied to LED, plasma display panel (PDP), fluorescent lamps, fluorescent sign boards in order to generate phosphor by receiving lights from the light sources and can include: phosphor particles containing sulfur to generate fluorescent lights by receiving lights; and a first protection layer that completely seals off and surrounds the phosphor particles so that oxidation of the phosphor particles can be prevented.
