摘要：The present invention is directed to an organic optoelectronic device, such as anOLED device, provided with a vacuum deposited conformal composite coating forprotecting the device from environmental elements such as moisture and oxygen. Thepresent invention is also directed to a method for vacuum depositing a conformal

composite coating directly onto an organic optoelectronic device, such as an OLED device,on a substrate. According to one embodiment, the invention provides a protected OLEDdevice comprising a substrate; an active region positioned on said substrate; a firstprotective layer disposed over the active region; and a second protective layer disposedover the first protective layer, wherein said second protective layer comprises multiplesub-layers that further comprise an alternating series of two or more first polymeric sub-layers and two or more first high density sub-layers.
