Quantum Dots Will Make Flexible Displays

judgecorp writes "Quantum dots are small semiconductors, whose properties are defined by their size and shape. British nanotechnology firm Nanoco has found they are ideal for displays, allowing the possibility of screens that can be rolled up — and which also use far less of the hazardous chemicals found in normal screens." In addition to being Cadmium free (a problem in the EU where the exemption for Cadmium in displays expires in 2014), they directly emit light using less power than traditional filtered color LCDs.

Think of the resolutions the human eye won't be able to distinguish; dots the size of percentage of a human hair to dots the size of potatoes, its all just a blur to our eyes. But hey, who am I to poop on progress on any scale?

Re:Cadmium

Yeah, the reporter (and then the submitter) somehow interpreted the company's press release about a cadmium free QD-LED display to mean normal LCD displays contained cadmium. And then to make it worse the submitter tried to expand on this misinformation by quoting one exemption for a single company's special purpose LED and wrongly applying that to a whole industry and regulatory body. Sigh.

These guys [extremetech.com] recently pulled it off with wireless power transmission to an antenna that goes around the rim of the lens. Just one monochrome pixel though! And a visible wire to that pixel.

What it would mean is that you could support multiple resolutions like on a CRT display. The fact that an LCD has to have a 'native resolution' at all is a nuisance for things like games. That and this thing should sidestep the horrible contrast problems LCD has.
