Samsung Electronics has confirmed that they are working on blue Quantum Dots. The aim is to take the picture quality of his QLED TVs to new heights. Blue quantum dots are the hardest to develop because they have the shortest lifespan and the lowest efficiency. Therefore, they have not yet been used in practice. This could change now.
Quantum dots are only a few nanometers in diameter and essentially filter the light. They use different colors. According to the South Koreans, there were always great difficulties with blue. But now a new milestone has been reached. The research is also documented in an article for the renowned science magazine Nature. The article “Efficient and stable blue quantum dot light-emitting diode” was published on October 14, 2020 in the journal.
The new blue Quantum Dots are 20.2% more efficient and, according to Samsung, have a lifespan of around 16,000 hours – measured at half the brightness for 100 nits luminance. However, the question remains of when Samsung will start using the blue quantum dots for its QLED TVs in practice. There might still be a long way to go until then, because specific information is not given.
