LG, Samsung Display Applied 17 Days Apart for QNED Trademark

LG Electronics and Samsung Display applied two weeks apart to trademark QNED for future generations of quantum nano emitting diode display technology, Patent and Trademark Office records show. LG’s application was Sept. 8, Samsung’s Sept. 25, both listing a wide diversity of possible QNED uses for TVs, smartphones, tablets and digital signage. A QNED display uses gallium nitride-based blue-light-emitting nanorod LEDs in place of OLED as the blue light source, emailed Display Supply Chain Consultants President Bob O’Brien Thursday. QNED, compared with OLED, promises higher efficiencies, improved brightness, longer lifetimes and the elimination of “burn-in issues,” said O’Brien. QNED is on Samsung’s product road map to follow the 2021 commercialization of quantum dot OLED displays, David Hsieh, Omdia senior director-displays, told the Display Week 2020 virtual conference in August. He described QNED as a hybrid between microLED displays and quantum dots. Nanosys Director-Marketing Jeff Yurek thinks Hsieh's description was "on point," he emailed Thursday. "You would still use QDs as a color conversion layer in a QNED stack." QNED is "a really cool idea and could bring some real benefits but I think it will be a while before we see QNED in products," he said.
