When the flexible display screen 100 is extended or contracted from the housing 300 through the opening 311, the two flexible display screens 100 are respectively attached to the first guiding surface 3111 and the second guiding surface 3112 to play a guiding role. To ensure stability during movement.
- engaging teeth are provided on a surface of the flexible display screen facing away from the display surface.
- the meshing teeth on each flexible display screen can be meshed with each other.
- the meshing structure between multiple meshing teeth is used to achieve a flat state of the display surface of the flexible display screen. demand.
- the display device based on the setting structure can provide double-sided display of the flexible display screen, provide more display contents and viewing angles, and can roll up the flexible display screen for easy carrying and display.
