Machine learning and “molecular Tinder” may change the game for OLED screens

To say there are a lot of molecules out there is kind of an understatement. So searching for one or two in particular is like looking for a needle in a galaxy-spanning haystack. Fortunately, the science of machine learning and the irrepressible need for humans to swipe left and right on things make the search a lot easier, as Harvard and MIT researchers have found.The molecules they’re looking for are blue organic phosphors, a critical component for organic light-emitting diodes — likely the next big step in display technology. OLEDs rely on molecules that produce light of a specific wavelength when introduced to a current, obviating the need for the backlights found in ordinary LED displays. This means the screen could be thinner, more flexible, and more power-efficient, among other…
