Active matrix displays and other electronic devices having plastic substrates

Abstract

A method of manufacturing a thin film electronic device comprises applying a plastic coating to a rigid carrier substrate using a wet casting process, the plastic coating forming a plastic substrate and comprising a transparent plastic material and a UV absorbing additive. Thin film electronic elements are formed over the plastic substrate, and the rigid carrier substrate is released from the plastic substrate. This invention provides a method of making transparent substrate materials suitable for a laser release process, through doping of the plastic material of the substrate with a UV absorber. This UV absorber absorbs in the wavelength the lift-off laser (for example 308-351 nm, or 355 nm) with a very high absorption.
