A New Era for Smartphone Displays?
Boston-based optics startup Metalenz has unveiled a groundbreaking under-display camera technology at Display Week 2026. The innovation promises to eliminate the need for notches or punch-holes in smartphone screens, potentially revolutionizing front-facing camera design.
The technology uses optical metasurfaces—flat-lens systems that replace traditional multi-lens camera elements.
Metalenz already has a proven track record. The company claims its metasurfaces are currently deployed in over 300 million consumer devices for time-of-flight sensors, a key validation for its manufacturing scalability.
Beyond the camera, Metalenz introduced Polar ID, a facial authentication platform that offers a significant security upgrade. Unlike conventional face unlock systems, Polar ID uses polarization data to distinguish real human skin from materials like silicone used in sophisticated masks. This could make it far more resilient to spoofing attacks.
The background context is clear. Current smartphone designs rely on notches and punch-hole cameras for front-facing lenses. Apple's Dynamic Island on the iPhone 14, for instance, houses Face ID components that require a larger cutout. Under-display cameras have long been the holy grail for achieving a seamless, full-screen design, but they have historically struggled with image quality. Metalenz's new approach may finally solve that trade-off.
