The good news about the successive OLEDs. After rumors that LG is launching OLED TVs of 55 "late 2011 and Samsung OLED 65" in 2012, now that researchers at the University of Michigan managed to double the light output and longevity of blue OLED. The researchers used the power of computer simulations to try many variations of the molecules already employed.
They were able to identify the mechanisms that control the efficiency of light emission of OLEDs. The simulation results were confirmed in practice: the new compounds have a blue OLED luminous efficiency (defined as the ratio between the amount of electric current supplied to the OLED and the amount of emitted light) of 9.4% is almost twice the previously accepted limits.
This discovery will still be translated into industrial application. Moreover, researchers do not say anything about the longevity of their new compound, while it is the weak point of traditional blue OLED.
