| - | [* black] This is the optical system for injecting two sets (focus planes) each of red, green and blue, image light into the diffractive waveguide. The bright colors on the top are not indicative of which color channel but rather due to light reflecting off diffraction gratings at an angle. |

| + | [* black] Did you get all that? That's okay—let's break it down a little further. |
| + | [* black] Lifting up one of the external sensor arrays, we find beneath: the optical system for injecting two sets of red, green, and blue image light into the diffractive waveguide—one set per focus plane. |
| + | [* icon_note] The bright colors on the top are not indicative of specific color channels, but rather result from ambient light reflecting off the diffraction gratings at an angle. |
| + | [* black] If you look closely, you may notice that the color spots are layered at different depths—each corresponding to a single layer of the waveguide. |
| [* black] The KGOnTech blog identified this structure in a Magic Leap patent in November 2016, said it was most likely what Magic Leap was doing, and briefly explained its function.

| - | [* black] If you look closely, you may notice that each color spot is at a different height to go to a single layer of the six layer waveguide. |

| - | [* black] Both LCOS devices feature a custom PCB variation so that both flex cables can be routed out the back of the display housing. |
