While 4K TVs are excellent, for the next couple of years most of us will still be selecting a 1080p model when we’re out shopping, and now we’ve got a little more detail about some of the new ones Sony announced last week . After letting its ” Triluminos ” RGB LED lighting technology fall by the wayside after 2009 because of its high cost, Sony has brought the brand back in this year’s HDTVs. Noted in the press release and highlighted today in the MIT Technology Review , this iteration uses QD Vision’s quantum dot technology to enhance the red/green/blue LED backlighting the series is known for. According to the CTO of QD Vision, the TVs start with a blue backlight — instead of the standard white LED — which stimulates quantum dots that emit “pure green and pure red.” Sony was very proud of its Triluminos tech at the show and our experience at demonstrations seemed to validate the quality of the approach. While we’ve been hearing about quantum dots for years , this is reportedly their first appearance in a mass produced consumer product, once it hits homes we’ll be able to tell if the wait was truly worth it.

A Canadian man in a vegetative state has used his thoughts to tell scientists that he is not in any pain, marking the first time a patient in such a condition has relayed information relevant to their care.

Historically, altering the lighting color of a room required draping a gossamer-thin cloth over a lamp or buying a new bulb from the store. Philips has sought to solve that most taxing of first-world problems with the hue, a smartphone-controlled LED bulb that can cycle through shades at your whim. As well as block colors, you can use photos to create palette and can control the units even when away from home. It’ll be an Apple Store exclusive from October 30th, with individual units setting you back $59 (£49, €59) and three-bulb introduction pack with a wireless bridge for $199 (£179, €199). If that seems a little steep, just console yourself in the knowledge that it’s a thousand times more useful than other lighting devices we’ve seen this year.
