The quantum dot product company, QD Vision, has made a breakthrough on the efficiency and performance of its quantum dot LED (QLED) technology.
QD Vision’s red, green and blue QLEDs now meet or exceed the 1953 NSTC color standard without using color filters or secondary effects.
The exceptional color performance of QLEDs translates into a fundamental 30-40% luminous efficiency advantage over the best known OLED technology.
QD Vision’s deep red QLEDs now offer greater efficacy at equivalent color than the best reported phosphorescent OLEDs, and its green and blue QLEDs match the performance of fluorescent OLEDs, but with far superior color performance. For example, red QLEDs fabricated by QD Vision consistently achieve peak external quantum efficiencies (EQEs) of more than 18% and efficacies of more than 22 lm/W and 18 Cd/A, at 1931 CIE color coordinates of (0.68, 0.32).
The company will present these technology achievements at SID 2011 on May 17, session 12 at 2:20pm.
