Abstract:
1. An encapsulation method of an environmental sensitive element, comprising: forming the environmental sensitive element adapted to be folded along at least one fold line and a first rib on a first substrate, wherein the first rib surrounds the environmental sensitive element; forming a protection layer on the environmental sensitive element for encapsulating the environmental sensitive element; forming a getter layer on the environmental sensitive element, wherein the getter layer is not located on the fold line; forming a first encapsulation layer to encapsulate the getter layer and the first rib, wherein the getter layer is located between the protection layer and a portion of the first encapsulation layer; forming a first barrier layer to encapsulate a portion of the first encapsulation layer located on the first rib, wherein the first rib, the portion of the first encapsulation layer located on the first rib and the first barrier layer form a barrier structure; and providing a second substrate on the first substrate, and forming a filling layer between the first substrate and the second substrate, wherein the second substrate is bonded to the first substrate by the filling layer, and the filling layer encapsulates the environmental sensitive element, the first encapsulation layer and the barrier structure, the first encapsulation layer, second substrate, the filler layer, and the protection layer forms a package material, the barrier structure disposed between the first substrate and the package material and surrounding the environmental sensitive element.
