A display screen having a mirror function, a control method, a device and a terminal. The display screen includes a screen lens (20), a liquid crystal screen (22) and a nano suspension layer (21), wherein the nano suspension layer (21) comprises an upper plate (210), a nanomaterial layer (211) and a grounding plate (212), the upper plate (210) is disposed between the screen lens (20) and the nanomaterial layer (211), the grounding plate (212) is disposed between the liquid crystal screen (22) and the nanomaterial layer (211). A magnetic layer (23) is also included, wherein the magnetic layer (23) is disposed on the back side of the liquid crystal screen (22). The control method comprises: when closing the trigger signal is received, controlling the magnetic layer (23) to provide a static magnetic field perpendicular to the display screen; when opening the trigger signal is received, controlling the upper plate (210) to provide a voltage, or controlling the upper plate (210) to provide a voltage and controlling the magnetic layer (23) to provide a static magnetic field perpendicular to the display screen. |
