When the adapter 122 rotates relative to the bracket 112 while driving the screen body 121 to rotate, the signal transmitter located on the back plate 121a will be displaced and will no longer be aligned with the signal receiver 132b fixed on the connector 114 .

When the signal receiver 132b of the second part 132 cannot receive the signal sent by the signal transmitter of the first part 131, it will trigger the controller (not shown) to send out a sensing signal so that the display screen 12 responds to this sense. Measure the signal, and provide the sound Light effects or other ways to remind users to increase the overall height of the screen to avoid collisions.

For example, in this embodiment, the display device 100 responds to a sensing signal sent by a controller (not shown) to display a pattern or text on the display surface 121b to remind the user to increase the overall height of the screen. In another embodiment of this specification, the display device 100 responds to the sensing signal sent by the controller (not shown), and uses a buzzer to remind the user to increase the overall height of the screen.

Please refer to FIG. 3A to FIG. 3C. FIG. 3A to FIG. 3C are perspective views showing partial structures of the display device 300 at different angles according to another embodiment of the present specification. The structure of the display device 300 is roughly similar to that of the display device 100, except that the structure of the sensor 33 of the display device 300 is different.

When the screen body 121 of the display device 100 is in a horizontal state, the other end of the trigger switch 331b is in electrical contact with the positioning member 331a. When the positioning member 331a rotates with the adapter base 122 relative to the connecting member 101d, it will make The trigger switch 331b generates displacement and no longer makes electrical contact with the positioning member 331a. At this time, the controller (not shown) in the screen body 121 will send out a sensing signal, so that the display screen 12 responds to this sensing signal to provide sound and light effects (such as displaying patterns or text or beeping) or Remind the user to raise the overall height of the screen in other ways to avoid collisions.
