New blue TADF OLED emitters are as efficient as the best blue PHOLEDs

Researchers from Kyushu University (led by Chihaya Adachi) developed a highly efficient blue OLED TADF (Thermally Activated Delayed Fluorescence) emitter that achieves almost 20% external quantum efficiency – similar to the best blue phosphorescent emitters. TADF OLEDs are free from the heavy metals used in phosphorescent emitters and so they could be cheaper and better for the environment. The main problem with blue phosphorescent OLEDs is the short lifetime which still makes it impossible to use them in commercial applications. The new TADF blue OLEDs has about the same lifetime as the blue PHOLEDs, but researchers are hopeful that it will be easier to improve the lifetime of the TADF emitters.

Philips’ latest OLED features 300 lumens at over 50 lm/W

Philips officially announced their latest OLED panel, the Lumiblade Brite FL300. This 12×12 cm (10×10 active area) new panel is very bright – up to 300 lumens. The FL300 is quite efficient (over 50 lm/W) and comes in either 3000K or 4000K. This panel uses thin-film encapsulation and is only 1.4 mm thick. The lifetime is 10,000 hours (LT70) at full brightness and 50,000 hours at 125 lumens. The CRI is over 80. Read more about Philips' latest OLED features 300 lumens at over 50 lm/W
