TDK Demonstrates World-First Ultra-Thin Meta-Optic Mirror for Prescription-Ready Smart Glasses

On 2 October 2026, TDK Corporation announced the successful demonstration of the world’s first direct retinal projection (DRP) display for smart glasses using an embedded “meta-optic mirror.” The flat mirror, measuring 150 nanometres thick, replaces conventional curved mirrors and offers approximately 80 per cent visible-light transmittance, allowing for cosmetically acceptable eyewear that can potentially integrate with prescription lenses. The technology prevents image leakage to enhance privacy and utilizes semiconductor-comparable manufacturing processes for cost-effective mass production. Currently supporting monochrome operation, TDK aims to demonstrate full-colour capability within the next few years. To accelerate development, TDK has entered a business cooperation agreement with QD Laser to combine retinal projection patents with laser modules. A working prototype will be showcased at CEATEC 2026 in Japan starting 13 October.
