Breakthrough makes OLED pixels inherently emit circularly polarized light, improving OLED brightness and efficiency

"eliminating external polarizers that had cut brightness up to 50%... chiral semiconductors using triazatruxene enables naturally spiraling light, record-breaking efficiency, brightness, polarisation levels... Samsung’s 5000-nit OLED uses on-cell film instead of external polarizer, gaining about 33% brightness, but relies on external films to suppress reflections – not polarized emission... traps chiral structure within stable, non-crystallising matrix... commercialization few years away"
