- Chirale semiconductors use a few tricks from Mother Nature
- The same brightness with much less energy consumption
- Large implications for future computers as well as screens
A pierced new OLED technology can mean smartwatches with longer battery life, more energy-efficient TVs and even brighter screens all around.
The breakthrough comes from researchers at the University of Cambridge and Eindhoven University of Technology, and this is what is called Chiral Semiconductors.
The research shows that these semiconductors can deliver “record-breaking” brightness and efficiency, and it can be a really big deal for any device with a display from the smallest smartwatch to the most massive OLED TV.
Here’s the science comes bit
One of the largest energy drains in the screens is the use of polarization layers, which in OLED -TVs are generally used to reduce ambient light leakage, ensures the exact contrast for which the technology is known. But this filtration process absorbs a lot of light – the fixed American Polarizers Inc says every polarizer absorbs more than 50% of the light that goes through it; It’s a lot of wasted energy.
This new technology is different because it makes its own polarization.
According to Eindhoven University of Technology, the semiconductor that the researchers have developed, circularly released, circularly polarized light that “bears information on the” left or right or right of the electrons. We know so well.
Making chirale semiconductors has proven to be very difficult, but scientists have found a way. When they picked up their inspiration from nature, the researchers created the right and left-handed spiral columns from stacks with semi-leading molecules. And these columns could transform the best OLED TVs, the best smartwatches and everything in between.
According to Professor Sir Richard Friend from Cambridge University, who co-led research, “Unlike stiff inorganic semiconductors, molecular materials offer incredible flexibility-so we can design brand new structures, such as chiral LEDs.
The semiconductor the team has created is based on a material known as the triazatrux or TAT card. It is gathered even for a helix, and electrons can spiral along it; The university describes it as being like the head of a screw.
These structures can be incorporated into OLED panels, as the first author Rituparno Chowdhury, from Cambridge’s Cavendish Laboratory, explains. “We have essentially reworked the standard recipe for producing OLEDs that we have in our smartphones, which allows us to capture a chiral structure within a stable, non-crystalizing matrix.”
The circularized, polarized LEDs demonstrated “record -breaking efficiency, brightness and polarization, making them the best of their kind,” says Eindhoven University of Technology.
We are still years away from watching this technology in one of the best TVs. But it is a major breakthrough that is relevant not only to TVs and other electronic objects. According to Eindhoven University of Technology, it also has major consequences for quantum calculation and what is known as “spintronics”: a research area that uses the electrons’ spin for stored and process information, and that one day can lead to faster, more secure computers.
