The adjusting module is a device for adjusting the visual angle of the display screen according to the needs of a user, namely, the user can freely switch the visual angle displayed by the display screen according to the needs of the content and the scene. For example, if a user is watching videos and pictures with friends, the visual angle of the display screen can be increased, and the user shares the videos and pictures on the display screen with friends, at this time, the visual angle of the display screen can be increased by 180 degrees through the adjusting module, and the content can be seen at any position in front of the display screen due to the 180-degree visual angle, so that the sharing requirement is met; if the user is in public places such as buses, subways or other people, in order to prevent intentional or unintentional peeping of surrounding people, the view angle of the display screen can be reduced, and at the moment, the view angle can be adjusted to a range which can only be seen by the user by the adjusting module, for example, the view angle is adjusted to 30 degrees, and the view angle is only 30 degrees, so that the content can be seen clearly only in the range of 30 degrees in front of the display screen.
The voltage control module is connected with the adjusting module and the viewing angle adjusting film 20 and is used for controlling the voltage output to the viewing angle adjusting film 20 according to the visual angle input by the adjusting module. The voltage control module and the adjusting module have a preset corresponding relation, for example, when a user needs to adjust the viewing angle of the display screen to 30 degrees, the voltage control module is required to output 5 volts to enable the liquid crystal molecules 21 in the viewing angle adjusting film 20 to turn over and align to reach a visual angle of 30 degrees, and when the user needs to adjust the viewing angle of the display screen to 180 degrees, the voltage control module is required to output 12 volts to enable the liquid crystal molecules 21 in the viewing angle adjusting film 20 to turn over and align to reach a visual angle of 180 degrees, and for other visual angles, the output voltage is required to be set as well, so that the liquid crystal molecules 21 turn over and align to change the viewing angle of the display screen to reach the angle required by the user. The viewing angle adjusting film 20 controls the liquid crystal molecules 21 to be aligned and turned over according to the received voltage so that the display screen has different viewing angles.
Specifically, the voltage control module includes a positive electrode plate provided above the liquid crystal molecules 21 and a negative electrode plate (not shown) provided below the liquid crystal molecules 21.
The viewing angle adjusting film 20 in this embodiment adopts spherical or ellipsoidal liquid crystal molecules 21, so that the inversion and arrangement of each angle, for example, 30 degrees, 60 degrees, and 90 degrees, are realized under the control of voltage output, the corresponding relationship between the output voltage and the viewing angle is preset, and the basis for setting the corresponding relationship is the inversion relationship between the passing voltage and the liquid crystal molecules 21. The viewing angle range of the display screen in this embodiment is 30 degrees to 180 degrees.

The cross-sectional shape of the first microcrystalline material layer 221 is trapezoidal.
The adjusting module is a device for adjusting the visual angle of the display screen according to the needs of a user, namely, the user can freely switch the visual angle displayed by the display screen according to the needs of the content and the scene. For example, if a user is watching videos and pictures with friends, the visual angle of the display screen can be increased, and the user shares the videos and pictures on the display screen with friends, at this time, the visual angle of the display screen can be increased by 180 degrees through the adjusting module, and the content can be seen at any position in front of the display screen due to the 180-degree visual angle, so that the sharing requirement is met; if the user is in public places such as buses, subways or other people, in order to prevent intentional or unintentional peeping of surrounding people, the view angle of the display screen can be reduced, and at the moment, the view angle can be adjusted to a range which can only be seen by the user by the adjusting module, for example, the view angle is adjusted to 30 degrees, and the view angle is only 30 degrees, so that the content can be seen clearly only in the range of 30 degrees in front of the display screen.
