"no deformation, wrinkling, leftover residues even when film thickness below 5 μm, ultrathin displays separated smoothly without carbon residue... integrates chemical vapor layer deposition-grown graphene between 2.9 μm thick ultrathin PI substrate/ its glass carrier... graphene absorbs UV distributing heat laterally enables clean lift off... consistent current density-voltage-luminance before/ after lift-off... improved efficiency, reduced costs... rollable displays, OLEDs, wearable/ stretchable sensors, implantable photonics"
