8.5 Quantum dot LED

Quantum dot (QLED) employs quantum dots in order to achieve significantly higher efficiency of device.

QLED displays promise better color reproduction, energy efficiency and cheaper manufacturing costs than OLED. QLED lightplates


 

Thinness:

It allows designers to make ultra-thin, flexible, and even transparent
video displays, it is not possible with existing technologies.

Color Purity:

It delivers 30 - 40% luminance (brightness) efficiency advantage
over OLED technology at the same color quality.

Energy-efficiency:

QLEDs have potential to be more efficient than OLEDs (> 2 times)
of the same colour purity.

Cost:

Ability to print large-area of QLEDs on ultra-thin flexible substrates
which will reduce manufacturing costs.


QLEDs Advantages:

  • reliability
  • energy-efficiency
  • tunable colour solution for displays and lighting
  • price-effective manufacture
  • ultra-thin, transparent, flexible devices

QLED will be commercially available approx. in 2014.
