AFFICHAGES À GAMME ÉLARGIE AVEC LUMINOPHORES VERTS À BANDE ÉTROITE

摘要

Phosphors emitting green light over a narrow wavelength range may be used to broaden the gamut of display devices. In one aspect, a light emitting device comprises a light emitting solid state device emitting blue or violet light, a first phosphor that absorbs blue or violet light emitted by the light emitting solid state device and in response emits green light in a spectral band having a peak at wavelength λ
