Samsung reveals the pixel trick behind Privacy Display
Samsung pulled back the curtain on Privacy Display last week. The Galaxy S26 Ultra launched on February 25th with the mobile industry’s first built-in Privacy Display.
Now, Samsung has revealed the brilliant technology behind the Privacy Display. It relies on a new OLED panel from Samsung Display that alternates between two types of pixels: Narrow and Wide.
Here’s how it actually works
In normal mode, both narrow and wide pixels spread light across a wide range of angles. When Privacy Mode is enabled, the display prioritizes narrow pixels that emit light straight forward, while wide pixels are reduced to a minimal level.
Samsung says the tech has been in development for 5 years, which tracks.
The company built Privacy Display with the ability to only apply to small portions of the S26 Ultra’s display, and it can hide notification pop-ups nearly perfectly. You’re not stuck blanking the entire screen every time you’re on a train.
You can set triggers for when the feature activates, such as during PIN, password, or pattern entry, or when notifications appear. No one wants to manually toggle a privacy filter every time they pull out a credit card to buy something online.

Early hands-on suggests the blocking works well at the Samsung booth, but real-world performance depends heavily on the angle. Double-press the side button, and it activates. It’s a quick trick in addition to the toggle in the Quick panel.
Samsung insists it doesn’t mess with brightness, color accuracy, or viewing quality when you’re looking head-on. However, it actually dims the screen brightness a little when tested with equipment.
