Recently, Nvidia published a patent for AR glasses called “Backlight free Augmented Reality Digital Holography Technology” (patent number US20250004275A1) on the official website of the United States Patent and Trademark Office.

This patent was submitted on June 14, 2024 and officially disclosed on January 2, 2025. The patent inventors include industry experts such as Jonghyun Kim, Ward Lopes, and David Luebke.
How to make AR devices more lightweight and display better has always been a research focus for AR glasses developers. Nvidia’s new patent is designed to address this pain point.
According to Nvidia’s related paper, traditional AR display solutions often use heavy folding optical components, making AR devices represented by AR glasses more bulky and having poor user experience (such as facial light obstruction and low contrast).
Nvidia researchers have abandoned traditional backlight systems and adopted digital holography and ambient light interference technology (self interference holography technology). Through specific optical designs (blocking incident light instead of adding light from additional sources) and deep learning based neural network control systems, outdoor display effects have been significantly improved, achieving more natural and clear virtual image presentation, helping to enhance immersive experiences while reducing the power consumption and weight of AR devices.
Among them, self interference holography technology is the core technology of this patent. This technology uses a phase modulated spatial light modulator (SLM) to produce destructive interference with ambient light, achieving selective shielding without the need for additional light sources. This is the principle behind AR devices reducing power consumption and weight. AR devices can use digital holography technology to achieve selective masking without the need for additional light sources. This precise selectivity can significantly reduce the power consumption of augmented reality devices, fundamentally solving the problem of poor display performance of AR glasses in strong light environments.
This system can be imagined as an adaptive color changing lens that can selectively dim specific areas of the field of view. Unlike traditional sunglasses that require overall dimming, this system only creates precise dark areas in areas where AR content needs to be displayed. This selective dimming method not only saves power, but also maintains natural vision in other areas.
The patent also shows that the approximate appearance of AR glasses is a pair of ordinary glasses, with a weight roughly equivalent to Meta Ray Ban. The lenses are fully transparent and support binocular display, with one camera on each side of the glasses.
Overall, digital holography and ambient light interference technology are expected to bring multiple substantial improvements to AR glasses:
·Significant reduction in power consumption: No need for backlight, greatly reducing energy consumption;
·Thinner and thinner design: Simplify the optical structure to achieve a slim and lightweight appearance that is more suitable for daily wear;
·Excellent outdoor performance: maintains clear AR display effect even in strong light environments;
·Enhance user experience: Non AR areas remain completely transparent, improving wearing comfort.
This is not the first time Nvidia has revealed this technology. Nvidia disclosed its collaboration with Stanford University in June 2024, utilizing AI driven holographic algorithms to optimize the display performance of holographic AR glasses. The new display element – Spatial Light Modulator (SLM) – does not manipulate the intensity of light, but rather the phase of light, enabling the reconstruction of 3D holographic images in front or behind SLM. Using this principle, the team has developed holographic glasses with a thickness of only 2.5 millimeters, utilizing waveguides, holographic near eye displays, and geometric phase lenses to manufacture extremely thin holographic AR glasses.
AR glasses are considered the next heavyweight product in the consumer electronics industry, but short-term shipments are still low, and Nvidia has not yet launched specific products, mainly in the stage of technology research and patent application.
