DESICCANT SEALING ARRANGEMENT FOR OLED DEVICES
First Claim
1. A method of encapsulating an OLED device, comprising:
- (a) forming an OLED device on a substrate;
(b) providing a protective cover surrounding the OLED device and the substrate;
(c) providing a first sealing arrangement between the protective cover and top surface of the substrate, to define a first chamber enclosing the OLED device;
(d) providing a second sealing arrangement sealed to define a second chamber sealed from and enclosing the first chamber; and
(e) providing first desiccant material in the first chamber and providing second desiccant material in the second chamber closer to the bottom surface of the substrate than the top surface.
