Monitors have evolved a lot in recent years, improving color coverage, adding different technologies, and improving refresh rates. A group of researchers from the School of Engineering at the Hong Kong University of Science and Technology (HKUST) has just published a study titled “Light emitting diodes from light fiber to everything color based on quantum cables of perovskite.
It should be noted that perovskite is a fairly rare material in the Earth’s crust. It is characterized by an orthorhobic crystal system, which also makes this material quite special.
This strange material is easy and cheap to produce, which is why it is so widely used in engineering and science. They are mainly used in the manufacture of high-efficiency photovoltaic solar panels. It is now also used to generate LEDs on fiber optic cables, also known as “fi-LEDs”.
They create flexible LED diode strips with quantum cables
This project was born with the aim of finding the best way to manufacture fiber cable LEDs, also called fi-LEDs. The biggest problem with these LED constructions has always been the material. Tests have often shown no or poor lighting problems.
The use of metal halite perovskite with an alumina membrane to create a quantum wire is the solution to mitigate the drawbacks. With this mechanism, a colored Fi-LED strip is obtained. Among other things, they could be used to manufacture textile clothing with lighting systems.
This represents a significant advancement in the field of fi LEDs. Future developments could focus on improving the efficiency and stability of fi LEDs, exploring new perovskite compositions for a wider range of emission colors, and integrating these devices into commercial textile products.
The HKUST researchers responsible for developing the project stood out
In the long term, these researchers could improve portable display technologies and lighting sources in unconventional ways. There is also talk of use for underwater applications, such as enhancement in swimming pools or diving areas.
It appears that these new fi-LED strips are flexible, elastic, retractable and waterproof. It seems pretty good that in the future, it could be used to create laptop or desktop computer screens. It could also be used to generate all kinds of wearable devices, such as glasses, watches and others.
Currently, this solution is in the development phase and there is still a long way to go before it can develop mass production. Even if this is true, it opens up a new world of possibilities in all segments. Imagine a motherboard with this type of LED strips, allowing for more complex designs and configurations.
On the other hand, different panel technologies could be developed for monitors, thus increasing the possibilities. Lighter and more efficient monitors could be developed. In addition, these could be roll-up or support other types of advanced configurations.
Interesting news that is worth following. We imagine that the first uses will be simpler and that as the technology matures, they will be confronted with the development of new projects.
