Innovative Quantum Dot material technology for stunning colours and energy efficiency in QLED televisions
Quantum Dot (QD) displays represent the next generation of TVs with enhanced, brilliant colours, precise visualisations, and greater energy efficiency. However, the materials, cadmium and indium, currently uses to produce these displays have multiple drawbacks. The use of Cadmium in the European area is restricted due to health safety reasons. Indium-based QDs have been highly lacking in performance. They have lower performing quantum yields (QY), measuring at averages of 80%, while also showing poor color performances due to high narrow emission spectrums (FWHM) at more than 40nm. Both technologies have very high production cost due to an extensive production process.
Avantama has developed Perovskite-based Quantum Dots that show the highest Quantum Yield and therefore the highest power saving properties. Their Perovskite QDs also show such a narrow FWHM that enables to span the whole colour spectrum as perceivable by the human eye. These features will allow to produce brilliant colours, precise visualisations, and energy savings for the next generation of TV screens. Their high performance QDs, add up to 50% more colours and save up to 30% of currently expended energy for operations compared to QD-enhanced LCD TVs from industry-leader Samsung.
Avantama are currently making sales on their R&D scale QDs, as well as sales on other nanomaterials in solution processed OLED and solution processed solar cells. They have currently 15 full-time employees that help them power the operations and support to deliver the sales requests. They have come to the point where the operations would have to significantly ramp-up. The project will allow to setup the production of Perovskite QDs on an industrial level in order to become a key supplier of optical film manufacturers in the TV screen production value chain.
