Samsung Display announced that it has developed a new technology that can recover around 80% of the quantum dots ink used in its QD-OLED production process. The recovered inks is refined through advanced synthesis technology that revives its purity and optical properties. The company will apply this technology, to its process and it is expected to save around 10 billion Won (around $7.3 million USD) each year in QD materials cost.
It turns out that even though the QD layers are inkjet printed, there is still significant waste of materials, as around 20% of the total QD ink used in the process remains in the nozzles and cannot be used. This new technology will enable SDC to make its QD-OLED panels more competitive with other large-area panel technologies.
