- Chiraux semiconductors use some Mother Nature Tips
- The same brightness with much less energy consumption
- Major implications for future computers as well as for displays
A new pierced OLED technology could mean smart watches with a longer battery life, more energy -efficient televisions and even more shiny displays around.
The breakthrough comes from researchers from the University of Cambridge and the Eindhoven University of Technology, and it revolves around what are called chiral semiconductors.
Research shows that these semiconductors can offer record brightness and efficiency, and this could be very important for any device with a display of the smallest smart watch in the most massive OLED TV.
Here is the little science
One of the largest energy drains in screens is the use of polarization layers, which in OLED televisions are generally used to reduce ambient light leaks, make sure the specific contrast for which technology is known. But this filtering process absorbs a lot of light – the American polarrisers firm in incomes that any polarizer absorbs more than 50% of the light that crosses it; It is a lot of waxed energy.
This new technology is different because it makes its own polarization.
According to the Eindhoven University of Technology, the semiconductor that researchers have developed emits a circular polarized light which “carries information on the” left or right-handed “of electrons”. When normal silicon semiconductors are symmetrical, the chiral molecules are on the left or right and reflect. The most famous example is in DNA, where they form the double propeller that we know so well.
Makeing chiraux semiconductors turned out to be very difficult, but the researchers found a means. Inspired by nature, the researchers created columns in the right spiral and left-handed from piles of semiconductor molecules. And these columns could transform the best OLED televisions, the best smart watches and everything else.
According to Professor Sir Richard Friend at the University of Cambridge, who co-directed research: “Unlike rigid inorganic semiconductors, molecular materials offer incredible flexibility-allowing us to design entirely new structures, such as Chirals. It’s like working with a LEGO set with all kinds of shapes you can imagine, rather than rectangular bricks. “
The semiconductor that the team has created is based on equipment known as Triazaturuxene or Tat for short. He self-helps in propeller and the electrons can in a spiral; The university describes him as being like the head of a screw.
These structures can be incorporated into OLED panels, as a co-first author Rituparno Chowdhury, from Cambridge’s Cavendish Laboratory,. “We have essentially reworked the standard recipe to make OLEDs as we have done in our smartphones, allowing us to trap a chiral structure in a stable and non -crystallized matrix.”
The circularized and polarized LEDs have demonstrated “record efficiency, brightness and polarization, making it the best of their gender,” said Eindhoven University of Technology.
We are still years to see this technology in one of the best televisions. But it is a great breakthrough which is relevant not only for televisions and other electronic articles. According to Eindhoven’s University of Technology, it also has major implications for quantum IT and what is called “spintronics”: a field of research that uses electrons spin to store and process information, and this can lead to faster and more secure computers.
