TL;DR Xiaomi has announced that the Xiaomi 18 Pro series features a Smart Privacy Display that uses 1:1 alternating standard and baffled privacy pixels, cutting side brightness to roughly 1% beyond 60 degrees.
Unlike competitor panels that use Diamond or Pentile setups, Xiaomi uses a full RGB subpixel arrangement with ~9.5 million subpixels to maintain clarity without display quality degradation.
Privacy mode can be triggered via Quick Settings, the AI key, voice commands, app/page rules, location triggers, or front-camera shoulder-surfer detection.
Xiaomi is gearing up to launch the Xiaomi 18 Pro series this week, and ahead of the September 23 launch, the company has confirmed a few key details about the phones. We know that the Xiaomi 18 Pro series will come with a secondary rear display with plenty of unique features. Today, Xiaomi is lifting the curtain on the primary display features of the Xiaomi 18 Pro series, focusing on the previously leaked Smart Privacy Display aspects.
In a comprehensive Q&A and several announcement posts shared on Weibo, Xiaomi outlined the mechanics behind the new display panel on the Xiaomi 18 Pro series. Rather than applying a software overlay or relying on third-party privacy screen protectors that degrade display clarity and viewing angles almost permanently, Xiaomi’s solution operates at the pixel level (much like the Galaxy S26 Ultra’s Privacy Display).
The panel is divided into two alternating sets of pixels: standard wide-angle pixels arranged 1:1 with dedicated narrow-angle privacy pixels. The privacy pixels incorporate microscopic physical baffles on their left and right sides, restricting their beam angle.

When standard mode is active, both sets of pixels illuminate, behaving like a conventional flagship OLED. Once privacy mode is triggered, the standard pixels shut off, leaving only the baffled privacy pixels lit. From straight on, the user sees an unobstructed view, but at angles beyond 60 degrees, side brightness drops to roughly 1% of the front-facing output, rendering the display practically pitch-black to onlookers.
Crucially, the Xiaomi 18 Pro series’ display hardware features a “SuperPixel 2.0” full RGB subpixel stripe rather than a standard Diamond or Pentile arrangement. Because subpixels aren’t borrowed, Xiaomi claims the Xiaomi 18 Pro Max reaches roughly 9.5 million subpixels, comparable to a traditional 2K panel while drawing power typical of a 1.5K display. As such, the display’s output is claimed not to be compromised at normal viewing distances when the privacy feature is off.
