Description
Feng Zhan and co-authors build a record-setting green display pixel in this 2026 paper. Ultra-sharp screens need green light that is pure in colour and stays bright for years, a pair of goals that usually fight each other.
The team designed platinum-based glowing molecules with a stiff three-dimensional shape and bulky guards, which narrowed their glow sharply. Placed in a top-emitting device tuned like a tiny echo chamber, the colour narrowed further and hit the green point of the BT.2020 broadcast standard. Efficiency was high, and the projected lifetime to 90 percent brightness passed 540,000 hours at standard brightness, far beyond commercial display norms.
