ABSTRACT:
An improved transparent support substrate in an organic light emitting diode (OLED) device comprises an organic polymer support film and a composite layer on the support film which is disposed intermediate the support film and the diodes of the OLED; the composite layer has first and second discrete coating layers bonded together in opposed facing relationship; the layers are of material impermeable to oxygen and water vapor but contain inadvertent discontinuities which result in discontinuity-controlled permeation of oxygen and water vapor.
