A Step Forward in Quantum Dot LED Technology
The study published in Science Advances demonstrates an advancement that could bring highly efficient new quantum dot LED technology to your living room sooner. The researchers studied tiny changes that happen inside LEDs that use quantum dots, including slicing them into extremely thin slivers. Think of quantum dots as very small semiconductors that give precise colors and top-notch picture quality in our computers and TVs.
Improving QD-LEDs' Longevity and Efficiency
One way researchers suggest improving QD-LEDs' longevity and efficiency is to put them in 'an acrylate-based resin' to extend their lifespan. Doing so will help prevent the QD-LEDs from degrading so soon -- which could mean better-performing QD-LEDs and better picture quality for you. Researchers tested this in a few ways, including examining red, green and blue QD-LEDs. They developed a way to slice a QD-LED thinly to see what happens at different layers of material, where they saw structural and chemical changes. When QD-LEDs merge, they lose their shape and release more hydrogen and oxygen, which can speed up degradation. Encapsulating the QD-LEDs in a resin helped. That doesn't stop degradation completely, but slows it while improving efficiency and lifespan.
A Brighter Future for TVs?
CNET Editor in Chief David Katzmaier, who's been reviewing TVs for more than 20 years, said the MIT study finding is exciting for the TV world. 'For years, we've suspected that self-illuminated or electroluminescent quantum dots could be the basis of TVs that deliver better image quality than the current champ, OLED,' he said. 'Quantum dots have been used for more than a decade in TVs with LED and OLED light sources, but electrically excited QD-LED promises significant improvement.' If this advancement can be commercialized, it could lead to better image quality and energy efficiency, which is increasingly important with larger screens and brighter HDR material, Katzmaier said. However, don't expect this technology any time soon. He predicts it will be years before this tech is available, and even longer before it becomes affordable enough for OLED or LED TVs.
