Deuterium quadruples OLED display lifespan, maker claims
Deuterium's Impact on OLED Displays (2024)
Swapping hydrogen for deuterium in OLED materials boosts brightness, efficiency, and durability. Deuterated blue emitters solved the power-hungry blue pixel problem, and the approach has spread to red, green, and yellow layers. In lifetime tests, deuterated OLEDs reached four times the LT50 of standard versions, since the heavier atom slows unwanted chemical reactions. Panel makers are now weighing deuterated tech for smartphones, cars, and wearables.
In a lifetime study for OLED, the LT50, which represents the time at which 50% of devices fail, has been increased to 4X in deuterated OLEDs compared to their non-deuterated counterparts.

It looks interesting, but the article has too few details. Some more info in the first reference https://pmc.ncbi.nlm.nih.gov/articles/PMC11936013/ Anyway, IIUC it discuss a research lab method, that may be hard to escale to factory production.

I’ve just been swallowed by a rabbit hole on heavy hydrogen, the Norwegian hydro plant used to make fertiliser by splitting water and D being left behind, then them realising they could sell D₂O.
It being used in some medicines, and in semiconductor processes, then in preserving Blue OLED for longer.

Stable, NON radioactive isotope of hydrogen with one proton and one neutron in its nucleus.
