New Delhi, Nov. 18 -- If you thought quantum dots were the endgame for TV picture quality, there is already a new science project lining up to replace them. At the SID-MEC conference in Germany, researchers spent a good amount of time talking about "quantum rods" and how they might push TVs towards brighter HDR, richer colours and noticeably lower power use in the coming years. Jan Niehaus from Fraunhofer IAP-CAN, who has been working on quantum materials for a long time, shared one of the most concrete updates so far. The core idea is fairly easy to visualise. Instead of tiny spheres like the quantum dots we see in QLED TVs today, quantum rods are stretched out at the nanoscale. Because of that shape, they can be lined up in one directio...
