Nvidia has recently submitted a patent for a completely new design of augmented reality glasses that eliminates the standard backlight system and instead incorporates digital holographic technology. The patent is officially named “Backlight-free Augmented Reality Digital Holographic Technology” (US20250004275A1), and it was made public by the United States Patent and Trademark Office on January 2, 2025.
Innovative AR Visuals
This new invention makes use of a spatial light modulator paired with ambient light interference to generate AR visuals. Unlike traditional AR glasses that darken the whole lens, Nvidia’s method only shades the areas of the lens necessary for displaying AR content. This advancement could lead to improved energy efficiency and a more pleasant experience for users.
Enhanced Control System
The spatial light modulator is powered by a neural network-based control system, which guarantees sharp and lifelike virtual images. The design as a whole seeks to solve prevalent problems found in current AR glasses while keeping a style and feel akin to conventional eyewear.
Competitive Market Landscape
The augmented reality glasses market is experiencing growth, with major tech companies increasing their product lines. Last year, Meta launched its Orion glasses, and there are rumors that Samsung will present its own AR headset at the Galaxy Unpacked event on January 22. Apple is also developing its AR glasses, although they may not be available for another three to five years.
Naturally, as is common with patents, there’s no assurance that this technology will be brought to market anytime soon. It may require significant adjustments before it’s suitable for everyday consumers.
