QD Vision, producer of solid-state lighting and display products using nanotechnology, has demonstrated its latest quantum dot LED (QLED) technology advancements in performance and efficiency, which realize the possibility of the production of economical, full-color QLED displays, at 2011 SID conducted in May 17, 2011.
In addition to offering all of the performance advantages of emissive display technologies, QLEDs facilitate production methods and consume only 50% of the power consumption of highly effective OLEDs. QD Vision’s blue, green and red QLEDs fulfill or surpass the 1953 NSTC color criteria, while eliminating the usage of secondary effects or color filters.
QLEDs’ superior color functionality converts into a basic luminous efficacy of 30% to 40% when compared to ultra-efficient OLED technology. On comparison with superior phosphorescent OLEDs, the deep red QLEDs of QD Vision demonstrate superior efficiency at equal color. The performance of the company’s blue and green QLEDs are equivalent to that of fluorescent OLEDs. However, their color performance is far better.
For instance, at specific color coordinates, QD Vision’s red QLEDs constantly attain over 18% of optimum external quantum efficiencies (EQEs) and efficiencies of over 22 lm/W and 18 Cd/A. According to the Chief Technology Officer at QD Vision, Dr. Seth Coe-Sullivan, the performance attributes of QLEDs, including economical patterning, consistency, ultra efficacy and superior color, make them the future electroluminescent technology for solid-state lighting and display applications.
