Abstract :
Cyclic olefin copolymer (COC) was used as flexible polymer substrate for the next-generation flat-panel displays (FPD). Surface roughness and optical properties of different thermally treated flexible polymer substrates were observed with an atomic force microscope (AFM) and a visible spectrometer, respectively. In addition, in this study, we found that the turn-on voltages, luminance, and driving current of the flexible organic light emitting devices (OLEDs) were strongly affected by the thermal history of the flexible substrate.
