Samsung Display unveiled 'QD-OLED Penta Tandem', a new premium technology brand built on its proprietary five-layer organic light-emitting structure, a core innovation unique to its QD-OLED panels. Samsung Display announced that it has completed trademark registration for the new brand, created to highlight the distinctive value of its five-layer organic light-emitting structure applied to QD-OLED panels for premium monitors and TVs. "Penta" comes from the Greek word for the number five.

QD-OLED expresses color using quantum dots that respond to light, with the blue emitting layer serving as the light source due to its high energy within the visible spectrum. Beginning last year, Samsung Display advanced the blue emitting layer stack from four layers to five, and applied the latest organic materials, completing a new generation of QD-OLED that delivers superior picture quality, efficiency, and peak brightness.
