OLEDs and other electronic devices using desiccants

摘要

Electronic devices that use desiccants for protection from moisture. The electronic devices comprise a substrate (12) and an electronic organic element (22) disposed over the top surface of the substrate. The substrate has one or more voids (14) which store desiccants (24). The voids penetrate partially or completely through the thickness of the substrate. An environmental barrier (20) is disposed over the electronic organic element and the voids. Also provided are methods for making electronic devices that use desiccants.
