A provider of OLED solutions for lighting and display applications, Novaled has developed a white OLED structure that has a lifespan of 100,000 hours at a brightness of 1000cd/m2.
The OLED structure utilizes a material that emits fluorescent blue color and attains a brightness of 60 lm/W. It delivers a color rendering index of 87 and attains CIE color coordinates and light emission spectrum of 0.429 and 0.470, respectively. The attained CIE color coordinates and light emission spectrum is very near to illuminant A and within the US Department of Energy quadrangles.
highly efficient Novaled OLEDs
The company intentionally used a commercially available and classical fluorescent blue emitter material for the OLED stack. The blue emitter material, combined with the LED, delivers less power efficiency than the phosphorescent emitters. But because of the benefits of the company’s PIN OLED technology and materials enable the OLED stack to attain very high values.
The blue emitter material guarantees a high lifespan for OLED units and enables high device stability. It also covers the total visible color range and results in a high color rendering index value. The OLED sample features the NET 61 material and the company’s light extraction technology and enhances the light’s angular dependence. Novaled’s PIN OLEDs meet the specifications for lighting applications and are suitable for luminaires and OLED lamps.
