Samsung Display announced a new QD-OLED brand, for its latest five-layer fourth-gen QD-OLED panel technology, called “QD-OLED Penta Tandem”. The Penta part refers to the five layer stacked OLED architecture. All QD-OLED panels have always used a stacked architecture, but as tandem OLEDs become more popular, Samsung adds the tandem word to its QD-OLED panel branding.
Samsung says that the new five-layer design increases the energy efficiency, brightness and lifetime of its QD-OLED panels. This enables higher-resolution monitors, and Samsung has managed to produce a 27″ 4K (160 PPI) panel with this new technology (which it says is the world’s first OLED panel to achieve that), and also a 31.5″ 4K panel, certified DisplayHDR True Black 500.
SDC says that compared to last year’s four-layer QD-OLED, Penta Tandem improves luminous efficiency by 1.3 times and extends lifespan by 2 times. As a result, products featuring QD-OLED Penta Tandem technology achieve industry-leading peak brightness of 4,500 nits for TVs and 1,300 nits for monitors, based on 3% OPR (On Pixel Ratio, the ratio of active pixels among all pixels composing the screen).
Samsung will roll out its latest Penta Tandem OLED panels for all monitor size categories from 27″ to 49″, as OLEDs increase their premium monitor market share.
