QD Vision Announces Breakthrough QLED Efficiency Results

(Nanowerk News) QD Vision, Inc. (www.qdvision.com), manufacturer of Color IQ™ optical components for LCD applications, today announced breakthrough results on next generation quantum dot light emitting devices (QLEDs), which are currently in advanced development stage. QLEDs are a quantum dot-based light emitting technology, which in the future will be used in applications such as electronic displays and solid-state lighting.
QD Vision’s latest QLED performance results are currently published in the 21 April 2013 issue of Nature Photonics ("High-efficiency quantum-dot light-emitting devices with enhanced charge injection"). In the article, QD Vision reports achieving 18% External Quantum Efficiency (EQE) which puts QLEDs near the fundamental efficiency limit of the technology. These results are two times higher efficiency than previously reported state-of-the-art efficiency of a QLED device. QD Vision’s current and luminous power efficiency are better than the best evaporated OLED result of the same color coordinate, and significantly better than what solution-processed OLEDs have thus far achieved.
“This paper clearly demonstrates the fundamental efficiency advantage that QLEDs have over any other emissive display technology. Achieving this milestone is a great breakthrough and the result of years of hard work and dedication to achieving what others may have thought impossible,” said QD Vision co-founder Seth Coe-Sullivan.
While at an earlier stage of development and commercialization than QD Vision’s Color IQTM products, QLED performance is already suitable for use in certain products that require precision color solutions in an ultra-slim form factor, including monochrome visible and infrared displays, and lighting devices for machine and night vision applications.
QD Vision’s recent breakthrough QLED efficiency result, as well as the recent launch of the Color IQ optical component demonstrates the potential of quantum dots to be the most compelling light emitting material today and for next generation displays.
