1. A detachable screen protector, comprising:
a functional film, which comprises a front surface facing towards a screen and a back surface; and
at least one adsorption sheet, which comprises a first side that is permanently fixed to the front surface of the functional film in a margin area; and a second side that contacts a screen surface; the adsorption sheet is elastically deformable to fit to the screen surface, making the screen protector attachable to the screen by removing air and forming a hermetically sealed area with lower air pressure than atmosphere between the adsorption sheet and the screen surface; and detachable from the screen by refilling air in the hermetically sealed area with lower air pressure than atmosphere between the adsorption sheet and the screen surface; the hermetically sealed area with lower air pressure than atmosphere is configured to generate an air pressure to keep the adsorption sheet attached to the screen surface.
