Abstract
A protection film for an electronic device includes an adhesive layer including a first surface to which an electronic device is attached, and a film layer which contacts a second surface of the adhesive layer and includes at least one member, where a thickness of the adhesive layer satisfies Inequality 1: z≤(5.1x+57.4)·ln(y)−(14.7x+140.5) where z is the thickness of the adhesive layer in terms of micrometers, x is a modulus of a member of the film layer which directly contacts the adhesive layer in terms of gigapascals, and y is a total thickness of the film layer in terms of micrometers.
Claims23
A protection film for an electronic device, the protection film comprising:
- an adhesive layer including a first surface to which an electronic device is attached;
- and
- a film layer which contacts a second surface of the adhesive layer and comprises at least one member,
- wherein the thickness of the adhesive layer satisfies Inequality 1:
- z≤(5.1x+57.4)·ln(y)−(14.7x+140.5)
- where z is a thickness of the adhesive layer in terms of micrometers, x is a modulus of a member of the film layer which directly contacts the adhesive layer in terms of gigapascals, and y is a total thickness of the film layer in terms of micrometers.
An electronic device comprising:
- a body which comprises at least one member;
- and
- a protection film which is attached onto at least a portion of a surface of the body,
- wherein the protection film comprises an adhesive layer which comprises a first surface attached to the surface of the body and a film layer which contacts a second surface of the adhesive layer and comprises at least one member, and a thickness of the adhesive layer satisfies Inequality 2:
- z≤(5.1x+57.4)·ln(y)−(14.7x+140.5) (2)
- where z is the thickness of the adhesive layer in terms of micrometers, x is a modulus of a member of the film layer which directly contacts the adhesive layer in terms of gigapascals, and y is a total thickness of the film layer in terms of micrometers.
