Samsung’s newly unveiled display tech could offer glasses-free 3D viewing on the Galaxy S28 Ultra. The official press release itself confirms the potential adoption of the screen technology in phones, tablets, and other devices.

A newly published paper in Nature details a collaboration between Samsung’s Visual Technology Team and POSTECH. The focus is on a new display architecture built around something called a Metasurface Lenticular Lens.

Instead of relying on traditional lenticular layers, Samsung uses nanoscale structures to precisely control how light is directed toward your eyes. The system can switch between standard 2D and immersive 3D using voltage control.

The display adjusts polarization states in real time; users can toggle depth effects on demand. Samsung claims a viewing angle of up to 100 degrees, which is roughly six times wider than older glasses-free 3D implementations.

This eliminates the rigid head positioning that killed earlier attempts. You are no longer locked into a narrow zone where the effect works. Move naturally, share the screen, and the 3D holds up. The entire optical layer comes in at just 1.2mm thin.

This approach of the South Korean tech giant fits into modern OLED stacks without forcing major design trade-offs. The team has already tested the concept on real OLED panels using a fabricated 50x50mm metalens.

The timing lines up with the Galaxy S28 generation, especially as Samsung continues to push display differentiation beyond brightness, refresh rate and Privacy screen.

A switchable 3D panel fits naturally into that strategy. It also opens doors for the Galaxy Z Fold lineup, where larger screen real estate makes depth effects more meaningful for gaming, media, and even multitasking.

If Samsung gets this right, glasses-free 3D will not feel like a gimmick anymore.

With the demonstration of switchable 2D-to-3D display tech, Samsung is not just refining smartphones, tablets, and commercial displays anymore. It is rewriting how depth itself is perceived on a flat slab of glass.

In a newly published paper in Nature, Samsung, alongside POSTECH, details a switchable 2D to 3D display built around a metasurface lenticular lens. The reveal hints that it quietly solves the problems that killed 3D on mobile long ago.

The new tech allows the display to decide when to behave like a normal panel and when to bend light into a multi-view field. The switch happens through polarization control, effectively toggling the metalens between concave and convex states.

• In 2D mode, the optics cancel out. Light passes straight through. You get a clean, high-resolution image, no penalties.
• In 3D mode, the same layer reshapes the light field. Depth appears. Perspective shifts with viewing position; no glasses, no tracking.

Samsung is pushing the viewing window to 100 degrees. It means multiple people can view the same 3D scene from different angles. Samsung’s metalens sits at just 1.2 mm, thin enough to integrate into an OLED without redesigning the device.

What this means for future Galaxy devices

Expect 3D to emerge as a premium toggle, not a permanent mode. A glasses-free 3D mode on a Fold could turn it into a portable light field viewer. Tablets could quietly become the first mainstream 3D consumption devices.
