The Dependence of PET Layer on the Thermal Stability of PET-ITO Substrate for Mobile Electronics
The PET-ITO substrate has been usually applied to many flexible applications such as selectively conducting films, flexible printed circuit, display panels, interconnections, terminals, etc., where the PET-ITO substrate has a main role to enhance the performance in the components of touch screen panels, solar cell panels and so on. Today’s flexible technology is issued on forming fine pattern, pattern alignment and mass-productivity on PET-ITO substrates, which is strongly related to thermal shrinkage and expansion of the substrate[1~5]. We investigated in this study the thermo-mechanical behavior of PET-ITO substrate using a thermo-mechanical analyzer (TMA) in order to analyze thermal strain with varying temperature.
