Abstract
A solid filler material is used to encapsulate active TFEL components supported by a substrate and disposed within a cavity. The cavity is created by affixing a rear cover plate to the substrate. The filler material is injected into the cavity as a liquid but cures to a solid under the influence of heat. This provides an effective moisture barrier and enhances the structural integrity of the panel rendering it immune to problems caused by changes in air pressure or caused by vibration.
