ZDNET’s key takeaways

• Samsung unveils a Privacy Display filter at Unpacked.
• The filter protects screens from prying eyes and can be turned off as needed.
• The Galaxy S26 Ultra is the only model so far to feature this innovation.

Privacy Display overview

Most of the updates to the new Galaxy S26 series announced at Samsung Unpacked were iterative—no major camera upgrades, no ultra‑powerful battery, and no groundbreaking AI features. The standout was the Privacy Display feature on the S26 Ultra, which may be the most significant smartphone innovation in years.

The Privacy Display lets you read the screen clearly when looking straight on, while preventing side‑viewers from seeing the content. You can disable it at any time to share what’s on the screen.

I’ve been a fan of privacy screen filters since the BlackBerry days in the 2000s—useful for keeping curious eyes off my screen on buses, trains, or planes. While I still appreciate a filter, it can be annoying when I want to show a video to my husband or kids.

Privacy Display’s best trick

The S26 Ultra’s implementation lets you toggle the filter on anytime, giving you control over when information is hidden or shared.

Key capabilities

• App‑specific activation – Assign the Privacy Display to particular apps. When a notification from a listed app appears, only that notification is shaded from side angles.
• Black Matrix technology – Samsung narrows the light path of each pixel. The display uses two pixel types:
  • Narrow pixels (primary light source when Privacy Display is on) have rings that make them visible only from the front.
  • Wide pixels illuminate the screen from all angles when the feature is off.

Privacy Display vs. screen protectors

Conventional privacy screen protectors—adhesive sheets of plastic or glass—often degrade image quality, wash out colors, reduce brightness, and interfere with fingerprint sensors.

Kerry Wan’s testing of privacy screen protectors on the S25 Ultra highlighted these drawbacks. Samsung’s integrated Privacy Display eliminates those trade‑offs by embedding the technology directly into the panel.

Bottom line

If Samsung’s promises hold up, the Privacy Display could become the new standard for smartphones in the coming years. For everyone else, privacy filters will remain a necessary (if imperfect) workaround—complete with bubble‑removal, dust‑clearing, and the occasional screen‑tilt to share a TikTok.
