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.
