A report from Korea suggests that Samsung Display has decided to resume its QD Nanorod Diode (QNED) technology development, that it has paused a few years ago, following a technology breakthrough related to the QD nanorod arrangement and placement technology.
Samsung's QNED technology is based on blue emitting nanorods (somewhat similar to microLEDs), coated with QDs for color conversion. Samsung's nanorod and QD deposition are both based on inkjet printing. The company originally hoped to achieve pilot production in 2021, but it faced several technical challenges, and eventually decided to abandon R&D - until this resumed last year.
Theoretically, Samsung sees its QNED technology as a replacement for QD-OLED platform - to replace the blue OLED emitter with the QNED emitter. QNEDs may prove to be more cost-effective, and longer lasting.
