We present a thin-film dual-layer bottom barrier on PI that is compatible with 350°C backplane processing for OLED displays. We demonstrate OLEDs that survive bending over 0.5 mm radius for 10.000x. Furthermore, we show compatibility of the bottom barrier with the backplane process by fabricating AMOLED displays on GEN1-sized substrates.

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...

Organic light-emitting diodes degrade rapidly by means of local cathode oxidation when exposed to the ambient atmosphere, resulting in visible non-emissive areas called black spots. High performance inorganic based encapsulations are required to protect the OLED. We have applied a hybrid thin-film encapsulation stack consisting of two inorganic...

The availability of a high performance thin-film barrier is the most critical challenge in upscaling and commercializing flexible OLED products. We report a flexible thin-film-barrier technology that meets lifetime specifications for OLED lighting, and demonstrate it in rollable QVGA a-IGZO AMOLED displays. Roll-to-roll manufacturing of this...

Within the Holst centre a transparent barrier on foil has been under development which is based on low-temperature plasma deposited silicon nitride films as intrinsic moisture barrier, stacked with planarization layers to spatially separate defects in these films. OLED lifetime testing and water vapor transmission rate measurements using a Ca...
