Quantum dot manufacturer Quantum Materials has announced successfully completing a 7,000 hour continuous on-time durability test for the company’s cadmium-free quantum dots in a remote LED application.
The company says that the successful implementation of quantum dots with LEDs has been slow to progress, primarily due to the challenge of achieving the requisite reliability and durability to survive the heat generation inside the LED package without suffering thermal quenching and rapid performance deterioration.
The quantum dot LEDs were under continuous power at 2.5V DC at 70mA and were measured initially, incrementally and at the 7,000-hour mark, with no degradation of intensity, peak emission or colour purity.
