In the laboratories of Nagoya and Kyushu Universities, Japanese researchers have turned to artificial intelligence to solve one of display technology's most enduring puzzles — how to make blue light emerge from an OLED screen with near-perfect efficiency. By asking a machine to search a chemical space of over 19,000 virtual molecules, they found two candidates that human intuition alone might never have prioritized, each approaching the theoretical limits of light conversion. The achievement is less about two new molecules than about a new relationship between human intention and machine disco
