Fig. 3: Chromatic properties of the red-emitting micro-LED and the effect of the spectral linewidth on the chromaticity.
From: High efficiency, high color purity red micro-light-emitting diodes

a Color point created from the red micro-LEDs of Sample A plotted on the 1931 CIE chromaticity diagram. The color gamut of NTSC standard and Adobe RGB is also indicated on the diagram. b Chromaticity diagram of emission spectrum with Gaussian distribution at various peak FWHM and wavelength in the red wavelength regime
