First Claim
1. A display system comprising:
- a display configured to display image content on a plurality of depth planes by outputting a plurality of component color images, the display comprising;
a waveguide stack comprising;
a first plurality of waveguides, each of the first plurality of waveguides comprising first outcoupling optical elements configured to selectively outcouple light of a first component color, wherein each of the first plurality of waveguides is configured to output light of the first component color with a different amount of wavefront divergence than other waveguides of the first plurality of waveguides;
a second plurality of waveguides, each of the second plurality of waveguides comprising second outcoupling optical elements configured to selectively outcouple light of a second component color, wherein each of the second plurality of waveguides is configured to output light of the second component color with a different amount of wavefront divergence than other waveguides of the second plurality of waveguides; and
a third plurality of waveguides, each of the third plurality of waveguides comprising third outcoupling optical elements configured to selectively outcouple light of a third component color, wherein each of the third plurality of waveguides is configured to output light of the third component color with a different amount of wavefront divergence than other waveguides of the second plurality of waveguides,wherein the light of the first component color comprises light having a wavelength within a first wavelength range, wherein the light of the second component color comprises light having a wavelength within a second wavelength range, and wherein the light of the third component color comprises light having a wavelength within a third wavelength range,wherein the first plurality of waveguides totals a greater number of waveguides than the second plurality of waveguides.

Abstract
Images perceived to be substantially full color or multi-colored may be formed using component color images that are distributed in unequal numbers across a plurality of depth planes. The distribution of component color images across the depth planes may vary based on color. In some embodiments, a display system includes a stack of waveguides that each output light of a particular color, with some colors having fewer numbers of associated waveguides than other colors. The stack of waveguides may include by multiple pluralities (e.g., first and second pluralities) of waveguides, each configured to produce an image by outputting light corresponding to a particular color. The total number of waveguides in the second plurality of waveguides is less than the total number of waveguides in the first plurality of waveguides, and may be more than the total number of waveguides in a third plurality of waveguides, in embodiments where three component colors are utilized.
