Quantum Dots Will Make Flexible Displays 83

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.

    Might be great for a head-mounted display though, or augmented-reality contact lenses. Now that voice command is starting to catch on, the largest remaining hindrance to miniaturization is the display.

    or augmented-reality contact lenses

    The problem is transmitting the pixel data to the lenses wirelessly while also simultaneously feeding them power somehow: you can't really have wires going to your contact lenses. If that could be solved in a reasonable manner then sure, it would be great. I've been thinking to myself that it'd be neat to have some sort of a small plug behind your ear into which you can plug in a small audio cable, and then have the audio transmitted directly to your inner ear through cranial resonance. Now, combine that with augmented-reality contact lenses/glasses and you've got a really, really powerful system useful for things ranging from entertainment to industrial uses to military uses and even remotely-guided surgeries.

    We have a potential replacement for LCDs in the works already, and its far more advanced along the R&D chain.

    How do these displays compare to OLED which can also be rolled and are also less toxic in their production?
