No problem.The only competitor with bulk sales is Nanosys for "Cad" film.None of the competitors except Hansol ( semi- batch ) have supplied KG quantities to anyone for Cad free film.Like I said more difficult than we think.Samsung is the only cad free tv on the market at the moment.

"Samsung’s Quantum dots, however, are cadmium-free. They’re based on indium (In) instead. After much research and development, Samsung is currently the only company that produces cadmium-free Quantum dot displays. Samsung started focusing on Quantum dots in 2001, and has since registered over 150 patents on the subject."

In the chart below you can see the big difference in FWHM when you use InP instead of CdSe.If QMC can get their cad free materials below 40 FWHM i think we have a winner.It would be nice to see QMCs current specs to compare.

The accompanying table and figure are Yurek's update of StoreDot's original, which can be found in the previous article.
