Periodic Reporting for period 2 - Perovskite-QDD (Innovative Quantum Dot material technology for stunning colours and energy efficiency in QLED televisions)
Reporting period: 2020-03-01 to 2020-12-31
Quantum dot (QD) enhanced TVs (also referred to as Quantum-LED, or QLED TVs) have been deemed the leading technology when it comes to colour performance, and energy efficiency, but have come across some significant stumbling blocks preventing a larger positive impact on the market landscape. Cadmium, using as a standard material in TV production for the past, has been listed as a restricted substance in the European Area and as such are no longer suitable for QLED TVs. Although they perform at significantly better colour performance levels than indium-based QDs, the use of cadmium in EEE is restricted by the Restriction of Hazardous Substances. The other competing technology, Indium, have been recorded with lower quantum yields leading to more energy used and lower quality and durability in TVs.
The SME Instrument project has allowed Avantama to optimise its proprietary production processes to achieve a robust QD technology that meets the high standards of Quantum Yield (QY), with minimal Full Width Half Measure (FWHM), at lower production costs. Avantama's QDs thus meet the market requirements of being the most powerful colour performances ever recorded on tests, regulatory compliant, and cost-effective in production.
Pilots with optical film manufacturer and display maker were conducted successfully. Film fabrication and reproducibility were tested, and all of the target parameters (QY, FWHM, wavelength, yield) proved to be better on production scale than on R&D scale.
Following these results, reproducibility specifications for finalised commercial product have been defined. New equipment has been purchased, installed, qualified and tested in-house, making Avantama ready for mass-scale production.
Achievements of the customer pilots and main results of the project have been disseminated through online communication tools and events. Relevant new patents have been filed.
