Samsung is best known for its QLED TVs, but at CES 2022, after years of hype, the company’s Display subsidiary unveiled its new QD-OLED technology, promising to adopt LG’s best OLED TVs. The technology differs from your standard OLED in that it uses only blue organic light-emitting diodes. Those diodes then shine the light they produce through a series of quantum dots, allowing the panel to produce the full spectrum of colors visible to the human eye. The approach has several advantages.
The most striking thing, especially compared to the current OLED screens, is that the panel can be a lot brighter. In a demo that FlatspanelsHD saw at CES, one display produced over 1,000 nits of peak brightness across a 10 percent window. In comparison, some of LG’s more recent TVs can produce between 700 nits and 1,000 nits of brightness in the same range. Brightness is something LG has consistently tried to address with its WOLD panels. In December, the company’s subsidiary unveiled its “OLED EX” technology, claiming it would improve brightness by up to 30 percent compared to conventional OLED displays.
Another advantage of the technology is better color performance. The panels Samsung Display showed at CES 2022 covered 90 percent of the Rec. Color gamut 2020. LG’s WOLED panels, which are consistently praised by people for their accurate and vibrant colors, reach about 70 percent of the Rec. 2020 standard. Finally, the viewing angles have been improved. In addition to TVs, the technology will make its way into gaming monitors, with Samsung and Dell planning to use the technology in 34-inch displays.
We’ll have to see how the panels perform in the real world, but on paper, QD-OLED could easily become the new standard for high-end consumer TVs. One of the first companies to release a TV with a QD-OLED panel is Sony with its A95K sets. Unfortunately, Sony has yet to announce how much those TVs will cost, and we won’t know until we’re closer to release sometime in the spring.
