Abstract

Key technical issues of flexible stainless steel foil substrates are addressed for OLED display backplane applications. Surface roughness and corresponding planarization layer technology development will be the major factors for the stainless steel foil substrates to be used for commercial applications. Promising candidates for the planarization layer materials are reviewed and some of the properties are addressed. In addition, if the substrate is sustained to a constant voltage for guaranteed circuit operation, capacitive coupling through the insulation and planarization dielectric layer, from the conductive substrate to the electrode and circuit elements on it, is also carefully analyzed for panel design and operation. Especially for large size high-resolution display applications, low k and thick planarization layer should be used.
