Galaxy S26 Ultra's Privacy Display scores excellent figures in an independent test

While Samsung introduced multiple hardware and software improvements with the Galaxy S26 Ultra, Privacy Display is definitely the phone’s most exciting feature. It is what everyone is talking about it. It takes your privacy to the next level. But how well does it perform in real-world use?

It delivered excellent results in an independent test.

Globally renowned independent certification, inspection, and testing firm UL Solutions tested the performance of Samsung Display's Flex Magic Pixel technology on which the Galaxy S26 Ultra’s Privacy Display feature is based. The company recorded a side-to-front brightness ratio of 3.5% at 45 degrees and 0.9% or lower at 60 degrees.

This means that when the phone’s display is viewed from a 45-degree side angle, brightness drops to just 3.5% compared to viewing it head-on, making it difficult to see what is displayed on the screen. At a 60-degree angle, brightness visibility falls to less than 1%. These results show that Privacy Display works extremely well. In comparison, typical smartphone screens maintain around 40% brightness visibility from similar side angles.

More importantly, unlike privacy screen protectors available in the market, the hardware-based Privacy Display feature can be turned on or off at any time or configured based on usage scenarios. It can be applied only to specific parts of the screen, such as password and PIN entry fields, notification pop-ups, or selected sensitive apps. Additionally, it works from top and bottom viewing angles, where traditional privacy screen protectors are ineffective.

Samsung Display first showcased Flex Magic Pixel technology in 2024 at the Mobile World Congress in Barcelona, Spain. The Galaxy S26 Ultra’s OLED panel uses second-generation Flex Magic Pixel technology, and Samsung Display calls it LEAD 2.0. This version further enhances off-axis viewing angle blocking while improving overall panel efficiency.

Since 2020, Samsung Display has filed more than 150 patents related to Flex Magic Pixel, reinforcing its position as a leading OLED panel maker for mobile devices such as smartphones.
