Light emitting diodes, display systems, and manufacturing methods are provided. In an embodiment, by way of example only, a light emitting diode (“LED”) include a die and a lens. The die is configured to emit wavelengths of light within a first predetermined spectral range. The lens is disposed on at least a portion of the die and is configured to filter the light emitted from the die such that a second predetermined spectral range is emitted from the LED.
