Library of molecules addressing key shortcoming in OLEDs – Batch Uniform

Machine learning, promises to radically reduce the cycle time for computational chemistry. This invention is a library of molecules novel deep blue molecule for use in OLED displays, which were identified through the use of machine learning. OLEDs are brighter, lower power, thinner, lighter and more flexible than the crystalline layers in conventional LEDs. The biggest technical problem for commercializing OLEDs is the lifetime of the blue OLEDs used in these displays. Blue OLEDs historically have had a lifetime half that of red and green (roughly 14,000 hours to half original brightness when used for flat-panel displays). This invention was funded under the Samsung sponsored research agreement.
