The rear shell 12 is arranged on the back side of the screen assembly 11 and is connected to the screen assembly 11. The front side of the screen assembly 11 is the side that interacts with the user, and the back side of the screen assembly 11 is the side opposite to the front side. The rear shell 12 protrudes to the side away from the screen assembly 11 so that an inner cavity is formed between the interior of the rear shell 12 and the screen assembly 11. The PCB assembly 13 is arranged in the inner cavity, and the PCB assembly 13 is assembled on the screen assembly 11. Specifically, the PCB assembly 13 is connected to the back side of the screen assembly 11, which serves as a control element of the display 1. On one hand, the rotating bracket 14 is connected to the back side of the screen assembly 11 and the PCB assembly 13, and on the other hand, the rotating bracket 14 is also connected to the rotating mechanism 2 via a rotating shaft, so that the display screen can rotate relative to the rotating mechanism 2, so that the user can adjust the viewing angle of the display screen as needed.

[0037] In some embodiments, the size of the rear shell 12 is adapted to the size of the screen assembly 11. The rear shell 12 can be connected to the screen assembly 11 through a connector and adhesive. A first window 121 and a second window 122 are provided on the rear shell 12. The size of the first window 121 is larger than that of the second window 122.

The PCB board 131 is arranged on the side of the connecting ear 1413 close to the rear shell 12. The third screw connector 17 connects the PCB board 131 and the screen assembly 11. The third screw connector 17 is arranged at a position close to the center of the PCB board 131. The distance from the surface of the connecting ear 1413 close to the rear shell 12 to the rear shell 12 is smaller than the distance from the surface of the main body 1411 connected to the connecting ear 1413 close to the rear shell 12 to the rear shell 12, so that a step is formed between the connecting ear 1413 and the main body 1411. The PCB board 131 is arranged between two opposite steps, and the thickness of the PCB board 131 is less than the height of the step. In this way, the space occupied by the combination of the PCB board 131 and the first connecting part 141 is reduced, the space utilization between the rear shell 12 and the screen assembly 11 is increased, and the protrusion of the rear shell 12 is reduced, thereby reducing the thickness of the display 1 and improving the aesthetics of the display 1.
