1. A display system comprising:
a selective light transmission filter component of a film, a layer, or a coating having:
a transmittance spectrum comprising:
a first minimum value at a first wavelength within a first wavelength range of 400-460 nm,
a first maximum value at a second wavelength that is less than the first wavelength, and
a second maximum value at a third wavelength that is greater than the first wavelength; and
an average transmission of at least 80% across a visible spectrum that includes the third wavelength.
