Abstract

A foldable package structure including a first substrate, a second substrate, a plurality of adhesive layers and at least one environmental-sensitive electronic component is provided. At least one of the first and second laminated substrates comprises an ultra-thin glass plate. The foldable package structure comprises a predetermined folded region and the ultra-thin glass plate is disposed at one side of the predetermined folded region and stays away from the predetermined folded region.

4. The foldable package structure of claim 1 , wherein a material of the first substrate or the second substrate comprises polyimide (PI), hybrid PI, polyethylene terephthalate (PET), polyether sulfone (PES), polyethylene naphthalate (PEN), cyclic olefin polymer (COP), or glass fiber reinforced plastics.

5. The foldable package structure of claim 1 , wherein the first laminated substrate or the second laminated substrate comprises a substrate, an ultra-thin glass plate and an adhesive layer.

6. The foldable package structure of claim 1 , wherein a material of the first adhesive layer, the second adhesive layer or the third adhesive layer comprises an optical adhesive, a thermosetting glue or a UV-curing glue.

7. The foldable package structure of claim 1 , wherein the at least one environmental-sensitive electronic component is an organic light-emitting diode (OLED) element, an electrophoretic display element, a liquid crystal display (LCD) element, an organic sensing element or a solar panel.

8. The foldable package structure of claim 1 , wherein the second laminated substrate comprises the second substrate, a fourth adhesive layer and at least two pieces of a second ultra-thin glass plate, the at least two pieces of the second ultra-thin glass plate are respectively disposed at two opposites sides of the at least one predetermined folded region but keep away from the at least one predetermined folded region.

9. The foldable package structure of claim 8 , wherein the second laminated substrate further comprises a reinforced barrier layer disposed between the at least two pieces of the second ultra-thin glass plate and located within the at least one predetermined folded region.

10. The foldable package structure of claim 8 , further comprising a sidewall barrier structure disposed between the first and second laminated substrates and located by at least one side of the at least one environmental-sensitive electronic component.

11. The foldable package structure of claim 8 , wherein a material of the fourth adhesive layer comprises an optical adhesive, a thermosetting glue or a UV-curing glue.
