> TDK Corporation has developed a 150 nm thick meta-optic mirror for smart glasses that projects 4K resolution images onto the retina.

**TDK Corporation** has unveiled a direct retinal projection display for smart glasses featuring a 150 nm thick **meta-optic mirror**. This technology uses nanoscale reflectors to project images directly onto the retina, replacing bulky curved mirrors of the past.

The meta-optic mirror offers 80 percent visible-light transmittance and can be embedded into lenses using semiconductor-like processes. TDK also developed a full-color laser module and a control device capable of 4K resolution for future wearable devices.

This innovation ensures privacy as images remain invisible to others. TDK, partnered with **QD Laser, Inc.**, will showcase the monochrome prototype at **CEATEC 2026** on October 13 and at **electronica** in November 2026 to advance next-generation optical engines.
