Abstract:
A method of making a flexible environmental barrier for an organic light emitting device, comprising the steps of:(a) assembling a foundation by (i) providing a substrate; (ii) vacuum depositing a top by vacuum depositing a first polymer layer on the substrate, followed by vacuum depositing a first ceramic layer on the first polymer layer, then vacuum depositing a second polymer layer on the first ceramic layer; (b) constructing said organic light emitting device on the second polymer layer; (c) forming a cover by vacuum depositing a third polymer layer followed by vacuum depositing a second ceramic layer on the third polymer layer, then vacuum depositing a fourth polymer layer on the second ceramic layer; and (d) encapsulating said organic light emitting device by placing said cover over said organic light emitting device thereby forming said flexible environmental barrier encapsulating said organic light emitting device.
