High Quality Content by WIKIPEDIA articles! A quantum dot display is a type of display technology used in flat panel displays as an electronic visual display. Quantum dots (QD) or semiconductor nanocrystals are a form of light emitting technology and consist of nano-scale crystals that can provide an alternative for applications such as display technology. This display technology differs from cathode ray tubes (CRTs), liquid crystal displays (LCDs), but it is similar to organic light-emitting diode (OLED) displays, in that light is supplied on demand, which enables new, more efficient displays and allows for mobile devices with longer battery lives.
