But a handful of start-up companies have been plugging away at another display technology that could enhance LCDs and unseat OLEDs: quantum dots. These light-emitting semiconductor nanocrystals shine pure colors when excited by electric current or light and promise rich, beautiful displays that would be inexpensive and easy to manufacture…..
