Samsung Display has introduced a new screen film for QD-OLED monitors called QuantumBlack, and while the name sounds dramatic, the idea behind it is actually very straightforward. It is a new low-reflection, high-durability layer designed to tackle two of the most common complaints about OLED-style displays in everyday use: glare and surface fragility. Samsung Display says the film reduces light reflectance by 20% compared with its previous film, raises panel surface hardness from 2H to 3H, and plans to apply it across all new 2026 QD-OLED monitor products.

Samsung's Galaxy S26 Ultra was never going to be an easy phone to sell on dramatic upgrades alone. A lot of the early conversation around the device focused on how little had changed compared with the previous model, with the new Privacy Display feature standing out as one of the few headline additions. On paper, that sounds useful enough: it narrows viewing angles so people beside you have a harder time peeking at your screen. But now, for some users, that same display is becoming the main reason they are unhappy with the phone.

Samsung has dropped a new ad ahead of the Galaxy S26 launch, and it strongly points to a built-in "privacy display" mode that's designed to stop people nearby from reading your screen. The ad shows a simple "Zero-peeking privacy" toggle being switched on, and the content becomes unreadable to anyone viewing from the side

Samsung has just pulled the curtain back on a new twist to its QD-OLED lineup, called QD-OLED Penta Tandem. If that name sounds like a marketing bingo card, the idea behind it is actually pretty practical: it's a new way of stacking OLED light-emitting layers so the display can get brighter, more efficient, and sharper, without needing to increase the physical size of the panel.
