Abstract

Embodiments of the present invention disclose a display screen control method and apparatus, and a terminal. The method in the embodiments of the present invention includes obtaining a height difference and an acceleration that are generated when a terminal moves from an initial position to a target position and determining, according to the height difference and the acceleration, whether a first predetermined movement is satisfied. The method also includes when the first predetermined movement is satisfied, triggering the terminal to turn on a display screen.
