Encapsulation method of a polymer or organic light emitting device
First Claim
1. An encapsulation method of a polymer or organic light emitting device, said method comprising the steps of:
- forming an organic or polymer light emitting device having a metal layer serving as a metallic electrode, on a transparent substrate; and
wrapping said device with multiple polymer films without contacting said metal layer to protect said organic or polymer light emitting device from oxygen and moisture.

Abstract
The present invention relates to the encapsulation for extending the lifetime of a flexible organic or polymer light emitting device and, more particularly, to encapsulation by sealing with multiple polymer films to prevent the penetration of oxygen and moisture into an organic or polymer light emitting device. Due to the encapsulation of polymer light emitting device with the multiple polymer films, exposure to moisture and oxygen are prevented, which are causes of device degradation. When using a plastic substrate whose the thermal endurance is high, simultaneously, it has a thermal endurance effect to the Joule heat during device operation. Accordingly, there can be fabricated an organic or polymer light emitting display whose lifetime is extended through the encapsulation of an organic of polymer light emitting device with multiple polymer films.
