Abstract: The present disclosure provides an expanded screen. The expanded screen includes a display device, a fixed device, a first rotating assembly and a second rotating assembly. The fixed device is configured to be fixed on a display. The first rotating assembly is rotatably connected to the display device. One end of the second rotating assembly is rotatably connected to the first rotating assembly, and the other end of the second rotating assembly is connected to the fixed device. The fixed device rotates through the first rotating assembly around a first axial direction. The fixed device rotates through the second rotating assembly around a second axial direction. The first axial direction is a width extending direction of the display device and the second axial direction is a direction perpendicular to a display surface of the display.
