Abstract:
Disclosed is a substrate structure for manufacturing a flexible electronic device, including a supporting layer, a release layer covering the supporting layer with a first area, wherein the release layer is an aromatic polyimide, and a flexible layer covering the supporting layer and the release layer with a second area. The second area is greater than the first area. The adhesion force between the flexible layer and the supporting layer is stronger than the adhesion force between the release layer and the supporting layer.
Abstract:
A substrate structure applied in flexible devices is provided. The substrate structure includes a carrier; a release layer with a first area formed on the carrier, which has a first adhesion force to the carrier; and a flexible substrate with a second area overlying part of the first area of the release layer and contacting the carrier, which has a second adhesion force to the release layer and a third adhesion force to the carrier, wherein the first area is larger than or equal to the second area, the third adhesion force is greater than the first adhesion force, and the first adhesion force is greater than the second adhesion force.
