1. A display system comprising:
a stack of waveguides comprising:
a first waveguide comprising:
a first absorptive optical filter transmissive to light of a first range of wavelengths and absorptive to light of wavelengths different from the first range of wavelengths;
a first in-coupling optical element configured to receive light transmitted through the first absorptive optical filter; and
a first waveguide having a first major surface and a second major surface, wherein the first in-coupling optical element is configured to incouple light of the first range of wavelengths into the first waveguide;
a second waveguide comprising:
a first major surface and a second major surface; and
a second in-coupling optical element configured to incouple light, transmitted through the first absorptive optical filter and the first in-coupling optical element and having a second range of wavelengths different from the first range of wavelengths, into the second waveguide; and
a third waveguide, wherein the third waveguide is rearward of the first waveguide and comprising:
a first major surface and a second major surface; and
a third in-coupling optical element configured to incouple light having a third wavelength range into the third waveguide; and
a third absorptive optical filter forward of the third in-coupling optical element and between the second waveguide and the third waveguide.
