Recently, NVIDIA published a patent for AR glasses named "Backlight-Free Augmented Reality Digital Holographic Technology" on the official website of the USA Patent and Trademark Office (Patent No. US20250004275A1). It is reported that NVIDIA submitted the application for this patent in June 2024, and it will be officially released to the public in early 2025. This patented technology eliminates the traditional backlight system and instead uses digital holography and ambient light interference technology, achieving a more natural and clear presentation of virtual images through specific optical designs and a deep learning-based Control System. This means that users can obtain a clearer and more detailed AR experience under various environmental conditions without relying on traditional backlit displays.
