Abstract: A pixel of a light emitting diode module, display panel or other device, may comprise different colored sub-pixels, where one of the sub-pixels comprises a wavelength converting material, such as phosphor, to convert light emitted from an associated light emitting diode of that sub-pixel into a color other than the main color of light emitted from that sub-pixel. The wavelength converting material may have an amount selected to tune the color coordinates of the pixel. The amount of wavelength converting material may be determined in response to measuring the intensity of the spectrum of light emitted by the light emitting diode of the sub-pixel, or similarly manufactured sub-pixels, on which the wavelength converting material is to be formed. Methods of manufacturing the same are also disclosed.
