Karl Guttag Teardown Confirms Meta Ray-Ban Display Uses Lumus Waveguide, OmniVision LCOS, and Goertek Engine

Karl Guttag’s analysis of the Meta Ray-Ban Display (MRBD) confirms it utilizes a Lumus geometric waveguide, an OmniVision OPO3010 LCOS microdisplay, and a Goertek-designed projection engine. The report details that Meta selected off-the-shelf components rather than in-house MicroLED or diffractive waveguide solutions. Key findings include an effective resolution closer to 400x400 pixels despite the stated 600x600 specification, and a measured contrast ratio of approximately 600:1. Eye glow is present but minimal at about 1.5% of brightness reaching the eye, significantly lower than typical diffractive waveguides. The field of view is 20 degrees diagonal, though often utilized at under 16 degrees. The article notes specific limitations, such as image softness attributed to digital resampling and optical design, and identifies WhatsApp as the primary method for loading images.
