Abstract (en)
[origin: WO9902277A1] A sealing structure (190) for an organic light emitting device display (100). The sealing structure (190) comprises a metal film (175) overlying a dielectric film (150). The sealing structure (190) has low moisture and oxygen permeability. At least one of the metal layers (175) may react with moisture or oxygen to seal off pin holes. A net low stress sealing structure (190) may be formed by combining tensile and compressive films. The sealing structure (190) may be etched to create openings (160) for connection to outside circuitry. The innovative sealing structure (190) minimizes moisture leakage and vertical shorts between diode cathode (900) and anode (400).
