Photonics research makes smaller, more efficient VR, augmented reality tech possible by Staff Writers Raleigh NC (SPX) Feb 02, 2021
Researchers from North Carolina State University and the University of Texas have developed and demonstrated a new approach for designing photonic devices. The advance allows them to control the direction and polarization of light from thin-film LEDs, paving the way for a new generation of virtual reality (VR) and augmented reality (AR) technologies. "This is a fundamentally new device architecture for photonic devices," says Franky So, corresponding author of a paper describing the work. "And we've demonstrated that, using our approach, directional and polarized emissions from an organic LED or a perovskite LED without external optical elements can be realized." So is the Walter and Ida Freeman Distinguished Professor of Materials Science and Engineering at NC State. In practical terms, an approach that allows for directional control of light using thin-film LEDs makes it possible to develop VR and AR headsets that are substantially lighter and less bulky. And the improved efficiency of the devices means that you get more photons out of the display unit for every electron that you put in. For AR units, it also means that more light from the outside world gets through to the user. In other words, you'll still be able to see the image being superimposed on your view of the real world, and your view of the real world will be clearer. "Because the device we've demonstrated is simple to fabricate and can be easily scaled-up, our discovery of this strong directional and polarized light emission from OLEDs and perovskite LEDs has important applications for displays, lighting and other photonic applications," So says.

GameStop extends wild ride on Wall Street New York (AFP) Jan 25, 2021 GameStop continued its wild Wall Street ride on Monday with dizzying ups and downs seemingly powered by online chatter about the struggling video game retailer with a devoted fan base. GameStop shares were up 70 percent at one point in morning trades, after ending last week with a surge in price and rocketing some 800 percent in the past three months. Shares that were trading at $2.80 in April of last year topped $100 during morning trade on the New York Stock Exchange, despite analysts warning ... read more
