Samsung Display develops QuantumBlack film that reduces reflectivity of QD-OLED displays by 20%

Samsung Display has announced a new low-reflection film it calls QuantumBlack, which the company says reduces light reflection by 20 percent compared to its previous film and raises surface hardness from 2H to 3H on the standard pencil hardness scale.

The technology is being applied across all new QD-OLED monitor products launched this year, and Samsung Display has completed trademark registration for the name.

QD-OLED panels are capable of producing true black by cutting power to individual pixels entirely. In practice, however, ambient light reflecting off the screen can reduce the perceived contrast and undermine the black performance that differentiates the panel type from conventional LCD alternatives.

Low-reflection film has been part of Samsung Display's QD-OLED monitor lineup since its early stages; QuantumBlack represents the latest iteration of that approach.

A surface rated at 2H is more susceptible to scratching during routine handling, including movement and cleaning. The 3H rating achieved with QuantumBlack, according to Samsung Display's internal evaluations, provides resistance to scratching even from contact with a fingernail.

On the commercial side, several monitor manufacturers have already launched products that use the new film. ASUS has released a product under the name Black Shield, Gigabyte under Obsidian Shield, and MSI under Dark Armor.
