Samsung is investing an additional ₩13.1 trillion ($11 billion) in the R&D and production of quantum dot-enhanced organic light-emitting diode (QD-OLED) panels:
The QD-OLED technology promises to simplify (i.e. lower the cost of) production of OLED-based televisions and monitors, as well as enabling wider color gamuts, which is something expected from next-generation content. Contemporary WOLED panels from LG Display use a blue or white (yellow + blue) OLED emitter stack, and a WRGB color filter system on top with a variety of additional layers behind, between, and ahead of them. By contrast, a QD-OLED panel uses an OLED emitter stack (some believe, with two emitting stacks) with a quantum dot RGB color filter (also called quantum dot color converter, or QDCC) system on top.
Today's OLED panels feature 22 layers, whereas a QD-OLED panel may cut the number to 13, which means fewer deposition stages, lower material and production costs, and, perhaps, better yield. The QD-OLED technology is still considered to be rather challenging as Samsung has to solve light management issues. Meanwhile, according to Display Supply Chain, one square meter of an QD-OLED panel will cost around $26, whereas one square meter of a contemporary OLED panel costs approximately $95.
