- Abstract
Abstract: We present a thin‐film dual‐layer bottom barrier on polyimide that is compatible with 350°C backplane processing for organic light‐emitting diode displays and that can facilitate foldable active‐matrix organic light‐emitting diode devices with a bending radius of <2 mm. We demonstrate organic light‐emitting diodes that survive bending over 0.5 mm radius for 10.000× based on the high‐temperature bottom barrier. Furthermore, we show compatibility of the bottom barrier with the backplane process by fabricating active‐matrix organic light‐emitting diode displays on GEN1‐sized substrates.
