By phone, Auvin suggested that the panel industry's growing reluctance to use cadmium-based quantum dots (QDs) was a factor in the decision.
This raises additional questions. Nanosys, which makes the cadmium-based QDs in 3M's QDEF, now makes high-performance cadmium-free QDs, and 3M could presumably use them for a cadmium-free QDEF. Could it be that 3M thinks that QDEF will soon become a commodity, with the high-value part of the business going to QD replacements for matrix color filters. (Nanosys and others are calling this photo-emissive technology, despite the fact that the quantum dots used in QDEF and dot-on-chip are also photo-emissive.)
