They are saying right now, Cd-free QDEF uses 0.3g/m^2, and a 60" TV is almost exactly one square meter, so about 0.3g/60" TV. They also show a chart that suggests current QDEF cost is ~$30/m^2. That's .3g QD's and 50g resin. I would think that resin is fairly inexpensive and that most of the cost is in the QDs which would make the QD cost ~ <$100/g. The chart shows QDEF cost falling to <$10/m^2 sometime 2020-21.
