Title:The Nanosys Quantum Dot Solution for LED Backlighting

Quantum dots are a new type of phosphor that provides superior color properties compared with existing phosphor materials. They are made of semiconductor nanocrystals a few nanometers in size. By simply varying their sizes, quantum dots can be made to emit different colors across the visible spectrum. By combining green- and red-emitting quantum dots with blue LEDs, backlights with color qualities similar to those of the original RGB-LED backlights can be produced with a much lower system-level cost. This presentation introduces Nanosys’ QuantumRail product for mobile applications which is scheduled to launch in 2011 and is capable of delivering over 100% of NTSC color gamut.
