QD Vision, Inc.和麻省理工的最新红光倒置QDLED, CE of 20.5 cd/A, Luminance of 165000 cd/m2 文章题目:Ultra-Bright, Highly Efficient, Low Roll-off Inverted Quantum-Dot Light Emitting Devices (QLEDs) 发表于SID 2015 DIGEST 2015年7月29日。 期间性能如下: In this paper, we demonstrate a novel inverted red quantum dot light emitting device with high peak current efficiency (20.5 Cd/A), small efficiency roll-off at high driving current density, and high operational stability. Ultra-high brightness of 165, 000 Cd/m2 canbe achieved at current density of 1000 mA/cm2 with a driving voltage as low as 5.8 V, which, to the best of our knowledge, is a record luminance for existing red light emitting devices utilizing organic materials. The devices show long operational half lifetime of over 1445 hours at 500 Cd/m2 initial brightness or 355hours starting at 2000 Cd/m2. |
