The HUD Comparison: MicroLED vs. LCoS Displays in 2026 Frames
Nits, Outdoor Visibility & Optical Waveguide Efficiency
The Even Realities G2's Micro-LED display is independently measured at 1,200 nits peak brightness — bright enough to read outdoors. Meta has not published waveguide efficiency or an ambient-light threshold for it, and neither figure should be assumed from earlier versions of this article, both of which were invented.

01Display Technology Fundamentals
AI eyewear with a display typically uses one of two light-engine approaches: Micro-LED (Even Realities G2) or LCoS (Liquid Crystal on Silicon, used by some competitors). Micro-LED is self-emissive — each pixel generates its own light — which is how the G2 gets bright, readable output from a small panel.
The G2's confirmed peak brightness is 1,200 nits. Meta — sorry, Even Realities — has not published a panel size, pixel pitch, or a nits figure beyond that. Specific dimensions and a "3,000 nit" figure in earlier versions of this article were invented.
Neither this site nor any source checked has independent brightness or color-accuracy (ΔE) figures for LCoS-based competitors. Any specific number for those, including in earlier versions of this article, should not be relied on.
Peak Brightness: What’s Actually Confirmed (nits)
02Waveguide Efficiency: Not Published By Anyone
A display’s waveguide efficiency — how much light actually reaches the eye versus is lost in the optical path — is a real and meaningful spec. It is also not one that Even Realities, or any competitor checked for this article, has published for these products.
The specific efficiency percentages, brightness-at-the-eye calculations, and ambient-light thresholds in earlier versions of this article were invented and have been removed. If you need outdoor-readability performance for a purchase decision, that is a question for the manufacturer directly, or for hands-on reviews once they exist.

Editorial correction notice
The citations previously listed here named Even Realities, the Society for Information Display, and an ANSI/INFOCOMM standard as sources for brightness and waveguide-efficiency figures that were invented. None is listed here in their place.
