According to a bunch of engineering researchers over at the University of Toronto, they lay claim to having developed the world’s most efficient organic light-emitting diodes (OLEDs) -on plastic. Basically, this means manufacturers now have an alternative apart from rigid glass, which could very well pave the way for a future that sees dirt cheap flexible displays – which in turn, will result in cheaper devices if some of the cost savings were handed down to the consumers.
At the moment, majority of OLEDs are produced using heavy-metal doped glass so that high efficiency and brightness are achieved, but those qualities come at a cost – they are far more expensive to manufacture, and not to mention carry the properties of being heavy, rigid and fragile.
The team’s work was made possible thanks to a 50-100 nanometre thick layer of tantalum oxide, which is in essence, an advanced optical thin-film coating material. When applied on flexible plastic, it results in the highest-efficiency OLED device to date without the need to incorporate it on glass or anything of that sort. Bear in mind that it will still take some time before it makes it to large scale manufacturing, not to mention being ready for the mass market.
