Samsung has introduced a new feature in the Galaxy S26 Ultra called the Privacy Display. By stacking OLED pixels into two layers, the company aims to let users control who can see their screen while also managing the trade-offs in brightness and color performance.
The design of the S26 Ultra’s display is based on Samsung’s patented Round Diamond Pixel pattern. However, this version of the pattern places pixels on two separate levels. Every four pixels are grouped together, with some embedded in a raised structure that limits the direction from which light can escape.
When the privacy mode is activated, only the pixels within these raised structures are illuminated. That leaves half the screen’s pixels dormant, cutting the overall light output in half. This not only reduces brightness but also affects the richness of the colors displayed.
The impact of this design choice becomes clear when comparing the S26 Ultra’s screen to the S25 Ultra. At 50% brightness, the newer model’s screen appears dimmer and less vibrant. The change in how the pixels are structured seems to interfere with the way colors are blended, especially noticeable in the red hues.
The privacy feature is meant to be a tool rather than a permanent setting. Users can enable it when needed, such as when checking sensitive information like messages or financial details. However, when in privacy mode, the trade-off is a decrease in screen brightness and color intensity during those moments.
Even when the privacy mode is turned off, the screen still suffers from reduced light mixing efficiency. This limitation affects color blending, especially in the red subpixels. The raised structures that help with privacy seem to play a role in this issue, contributing to the perception of a less vibrant display.
A Privacy Feature That Costs Light and Color
Samsung’s new privacy display is a clever engineering solution, but it comes at a cost. The feature blocks some light to keep information secure, but in doing so, it also affects the overall visual experience. While the privacy aspect is effective, the hardware compromise affects brightness and color richness.
The company promotes the Privacy Display as a software-controlled toggle that gives users control over who can view their screen. But the teardown by iFixit reveals the hardware changes that make this privacy possible. These adjustments, while effective, fundamentally shift how the display performs, leading to a screen that protects your data while limiting part of your viewing experience.
Ultimately, the Privacy Display is a trade-off. It offers an advanced privacy feature that is more effective than typical privacy films. However, the engineering choices behind it result in a screen that is not as bright or colorful as before. The compromise highlights the challenges of balancing innovation with performance in smartphone design.
