Abstract:
1. A method of making an encapsulated display device comprising: providing a first substrate having at least one barrier stack thereon, the first substrate having an edge, the at least one barrier stack comprising at least one first barrier layer and at least one first polymer layer, wherein an oxygen transmission rate through the at least one first barrier stack is less than 0.005 cc/m providing a second substrate, the second substrate having an edge; placing the first substrate next to the second substrate so that there is a space between the first and second substrate, forming a seal between the edge of the first substrate and the edge of the second substrate, the seal having an opening therein; introducing a liquid into the space between the first and second substrate through the opening in the seal, the liquid selected from liquid crystals and electrophoretic inks; and closing the opening in the seal to form the encapsulated display device.
