Your next TV might be a quantum one. Sort of. Light-emitting nanoparticles called quantum dots are finally coming out of the lab and into our living rooms, bringing better colour to LCD flat-panel screens. The first TVs with the new technology, Sony’s Triluminos sets (pictured, right), reached stores this month. Reds are “rich, vibrant and vivid, green grass looks like ...

Osram is to develop glare-free adaptive headlights, where modulating multiple LED die within a headlight allows the shape of its beam to be varied in response to data from forward-facing cameras in the vehicle. Low-beams that adapt with vehicle speed are another aspect: at high speed the range of the light is automatically increased, while in city traffic the beam ...
