Abstract:
1. An adhesive layer, the adhesive layer being of an organic or polymer material and wherein said adhesive layer is bonded within a thick film dielectric electroluminescent display, said display comprising a composite thick film dielectric layer as part of a display sub-structure, to seal said thick film dielectric electroluminescent display, wherein said adhesive layer extends at least 3 millimeters beyond a perimeter of the display sub-structure and has one or more of the following functions: to reduce the ingress of moisture and atmospheric contaminants that react with layers of the thick film dielectric electroluminescent display; helps to contain the gaseous and vapour species generated within the thick film dielectric electroluminescent display during operation; inhibit chemical reactions that cause thick film dielectric electroluminescent display degradation; contain pressures within the thick film dielectric electroluminescent display; strengthen the overall mechanical integrity of the thick film dielectric electroluminescent display; and withstand mechanical and thermal stresses.
