Samsung Display has previously announced that it will phase out production of LCD screen materials and move to Quantum Dot LED (QD-LED) materials, and has decided to invest $11 billion to promote mass production of new materials by 2025. Although qD-LED is seen as the future of Samsung Display,media ZDNet Korea reported that Samsung has begun developing a successor to the technology, QNED.
QNED is not a new technology, but it is becoming a hot topic in the display industry, the report said. QNED is an acronym for the Quantum dot Nanorod LED and uses oxide TFT and quantum dot color filters similar to QD-LED.
The main difference between QD-OLED and QNED is the pixel material and pixel manufacturing technology itself. Samsung uses the inkjet method to spray the nanorod LEDs scattered in the solution into the pixel region to create qNED pixels, which are then self-aligned with the help of electrical signals.
QNED technology promises superior contrast, higher brightness levels, and faster response times compared to existing display solutions. According to UBI Research, Samsung Display is likely to start producing 30,000 QNED panels per month in Q2 2021. The source also said that once Samsung’s QNED-based TVs are commercialized, they will pose a significant threat to LG’s WOLED solutions.
Realistically speaking, the QNED TV is unlikely to go on sale next year because Samsung’s display still has some problems to address. Although production costs are said to be lower than OLED, micro-LED and QD-LEDs, the inkjet manufacturing method takes longer and the company is working to make it available for mass production. As an emerging technology that could take over QD-OLED, qNED may be in the mainstream for several years.
