[0031] like Figures 1 to 2 As shown, this embodiment provides a display device, which includes a display screen 1, a camera module 2, an angle adjustment mechanism 3, and a control module. The display screen 1 and the angle adjustment mechanism 3 can be mounted on a countertop 4, and the control module can be integrated with the angle adjustment mechanism 3. The display screen 1 is provided with a dynamic raster layer 11. The camera module 2 is used to collect facial and pupil information of the user in front of the display screen 1. The angle adjustment mechanism 3 is used to adjust the angle of the display screen 1 so that the display screen 1 faces the user directly. The control module can determine whether the user is present based on the facial information and can also adjust the dynamic raster layer 11 based on the pupil information so that the display center of the display screen 1 is aligned with the center of the user's pupil.

[0032] The angle of the display screen 1 is adjusted by the angle adjustment mechanism 3 so that the display screen 1 faces the user directly. The camera module 2 collects the user's facial and pupil information in front of the display screen 1. The facial information is used to determine if the user is the actual user. The dynamic raster layer 11 of the display screen 1 is adjusted according to the pupil information so that the display center of the display screen 1 is aligned with the center of the user's pupil. This effectively prevents other people from peeping at the user's screen information and protects the user's privacy to the greatest extent. No additional obstruction is required when performing sensitive operations such as entering passwords. The user experience is good. The screen light and viewing angle adjust with the user's line of sight, making it more humanized and intelligent. The operation is also more convenient and natural. It is highly adaptable and can adapt to the operation needs of different heights and viewing angles. It meets the needs of places such as banks that require high privacy protection and has broad market prospects.

[0033] Optionally, the dynamic grating layer 11 includes a liquid crystal layer and a voltage adjustment module. The voltage adjustment module is used to adjust the arrangement of liquid crystal molecules in the liquid crystal layer to adjust the tilt angle of the dynamic grating layer 11. The liquid crystal layer is made of liquid crystal material, and different voltages can be applied by the voltage adjustment module to change the arrangement of liquid crystal molecules, thereby changing the tilt angle of the grating, so that the screen light propagates only in a specific direction, similar to the Venetian blind effect.

[0034] Optionally, the angle adjustment mechanism 3 is a ball joint structure, which includes a ball 31, a socket 32, and a drive mechanism. The ball 31 is movably disposed within the socket 32 ​​and is connected to the display screen 1. The drive mechanism is used to drive the ball 31 to move within the socket 32. The ball joint structure is compact, flexible, stable, has a strong load capacity, is easy to install, and is lightweight. To facilitate driving and detecting the rotation of the ball 31 within the socket 32, the drive mechanism optionally includes a stepper motor and a gyroscope. The gyroscope is used to detect the current angle and direction of movement of the ball 31, and the stepper motor is used to drive the ball 31 to rotate within the socket 32.

[0035] The relative rotation of the sphere 31 and the socket 32 ​​can be driven by magnetic coupling. Optionally, both the sphere 31 and the socket 32 ​​are hollow structures. Magnets 33 are fixed to the outer surface of the sphere 31 and the inner surface of the socket 32, respectively. The driving mechanism includes a bracket 34, a first orthogonal servo motor 35 and a second orthogonal servo motor 36. The bracket 34 is connected to the socket 32. The housing of the first orthogonal servo motor 35 is mounted on the bracket 34. The output arm of the first orthogonal servo motor 35 is connected to the housing of the second orthogonal servo motor 36. The output arm of the second orthogonal servo motor 36 is connected to the sphere 31 through a connecting rod 37. The first orthogonal servo motor 35 and the second orthogonal servo motor 36 can generate power and use the torque generated by the magnet 33 to make the sphere 31 rotate relative to the socket 32.

[0036] In some embodiments, the angle adjustment mechanism 3 includes a cooperating cross spherical gear and a single-pole gear, with the cross spherical gear connected to the display screen 1. This configuration allows the angle adjustment mechanism 3 to have three degrees of rotational freedom in different directions, providing greater flexibility.

[0037] In some embodiments, the angle adjustment mechanism 3 is a multi-degree-of-freedom robotic arm, which includes a base, a connecting arm, a rotary joint, and an end effector arranged sequentially. The end effector is connected to the display screen 1. To facilitate driving the rotary joint to rotate, the multi-degree-of-freedom robotic arm may optionally also include a drive motor and a reducer, with the drive motor connected to the rotary joint via the reducer.

[0038] Optionally, the camera module 2 includes a first infrared camera and a second infrared camera that are spaced apart and embedded in the display screen 1. The first infrared camera and the second infrared camera are located at different positions on the display screen 1, such as one above and one below, to capture the same scene from different but known angles to create depth information, thereby enabling spatial calculation. The infrared function is used for auxiliary acquisition when there is insufficient light.

[0039] The operation process of the display device provided in this embodiment is roughly as follows:

[0040] The first step is for camera module 2 to collect the user's facial information and determine whether it is the user. If it is not the user, the process is interrupted.

[0041] The second step involves the camera module 2 capturing the user's facial information to determine if the user is facing the screen. If the user is facing the screen, proceed directly to the fourth step.

[0042] The third step is to issue an adjustment command to the angle adjustment mechanism 3 if the user is not facing the screen directly, so that the screen is facing the user directly.

[0043] The fourth step is for the camera module 2 to collect the user's pupil information, calculate the angle that each row and column of the screen grating needs to be adjusted, and issue an adjustment command to the dynamic grating layer 11 so that the screen light is only visible within the user's pupil range.

[0044] During the process of handling business, the user's face moves slightly and continuously, so the above process is constantly cyclical and adjusted in real time.

[0045] This embodiment also provides a terminal device, including the aforementioned display device. The angle adjustment mechanism 3 adjusts the angle of the display screen 1 so that the display screen 1 faces the user. The camera module 2 collects the facial and pupil information of the user in front of the display screen 1. The facial information is used to determine whether the user is the actual user. The dynamic grating layer 11 of the display screen 1 is adjusted according to the pupil information so that the display center of the display screen 1 is aligned with the center of the user's pupil. This effectively prevents other people from peeping at the user's screen information, maximizing the protection of user privacy and security. No additional obstruction is required when performing sensitive operations such as entering passwords. The user experience is good, and the screen light and viewing angle adjust with the user's line of sight, making it more user-friendly and intelligent. The operation is also more convenient and natural, with strong adaptability, adapting to the operation needs of different heights and viewing angles. It meets the needs of places such as banks that require high privacy protection and has broad market prospects.
