Abstract

A universal sheet (200) is configured to be cut to form a screen protector (200S) through a cutting process. The universal sheet (200) includes a usage layer (203), a buffer layer (202), and a bottom layer (201). The usage layer (203) includes a hardened film (2031) and a bonding film (2032) that is formed on the hardened film (2031), and a hardness of the hardened film (2031) is at least 5H. The buffer layer (202) includes a first buffer film (202a) attached onto the hardened film (2031) and a second buffer film (202b) that is attached onto the first buffer film (202a). A hardness of the hardened film (2031), a hardness of the first buffer film (202a), and a hardness of the second buffer film (202b) sequentially decrease. A thickness of the hardened film (2031), a thickness of the first buffer film (202a), and a thickness of the second buffer film (202b) sequentially decrease. The bottom layer (201) is attached onto the bonding film (2032). The universal sheet (200) is configured to be cut from the buffer layer (202).
