Thermal and Mechanical Effects on the Flexible Polymer Substrate

Article Preview

Abstract:

A novel flexible polymer was used for the new generation display panel, which was prepared by thermal annealing treatments. Atomic force microscope (AFM) and visible spectroscopy were employed to measure the surface roughness and the optical transparency of the substrates. Mechanical cycles bending were carried on the flexible substrates in this study. Surface morphology of the substrates after bending was observed by scanning electron microscope (SEM). The performances of the OLED device were compared for the samples with and without cycles bending.
