The ability to deposit OLEDs on flexible substrates has also led to revolutionary changes in device form factor, with foldable and rollable displays gaining market share, particularly for smart phones and IT products. The flexibility of OLEDs enables the design of devices that can unfold or unroll to reveal larger displays, with bi-fold and even tri-fold products now commercially available.
