Substrates based on these materials demonstrate excellent chemical resistance, low O2 permeability and superb physical and optical properties. These properties offer the potential of meeting the requirements for roll-to-roll processing of flat panel displays.

Appear™ 3000 and AryLite™ plastic films satisfy most of the necessary requirements for use as substrates in flexible flat panel displays. Preliminary evaluations have shown excellent physical and optical properties and chemical resistance. We now present further progress with respect to poly‐Si TFT array fabrication.

AbstractOptical films can be made by novel polyarylates with improved UV stability, light transparency and heat‐resistance. The present work relates to novel polyarylates made of bis(hydroxyphenyl)fluorene ortho disubstituted bisphenols. These materials feature a broad range of properties useful for optical applications, particularly for plastic and flexible FPD substrates.
