Ultra-Thin 1.2mm Voltage-Controlled Metalens Revolutionizes Glasses-Free 3D Viewing Angle to 100°
Overview
In April 2026, Samsung and POSTECH unveiled a groundbreaking metasurface lenticular lens that dynamically switches between high-resolution 2D and immersive 3D modes using voltage control. This ultra-thin 1.2mm metalens overcomes previous limitations by enabling a wide 100-degree viewing angle, allowing multiple viewers to enjoy glasses-free 3D simultaneously without sacrificing 2D image quality. Advanced manufacturing techniques, including Roll-to-Roll nanoimprinting, have drastically reduced production costs and enabled mass production, paving the way for integration into smartphones, tablets, medical imaging, and AR/XR devices. This innovation promises to transform user experiences and is expected to reach consumer markets by 2027-2028.
