[0037] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in FIGS.

[0038] In the display device 100 implemented in this application, by controlling the sizes of the light-transmitting area 22 and the light-blocking area 21 by the grating component 20, the amount of light transmitted out of the display screen 10 can be changed. When a larger viewing angle is required, the light-transmitting area 22 can be adjusted to become smaller, and at the same time, the adjustment display area 12 is controlled to display relevant content to ensure the light output, thereby ensuring the imaging quality when there are more people. When a smaller viewing angle is required, the light-transmitting area 22 can be adjusted to become larger, and at the same time, the adjustment display area 12 is controlled to be turned off to reduce the light output, thereby saving electric energy on the premise of ensuring the imaging quality.

[0039] In related technologies, in order to achieve the effect of a three-dimensional image on a display screen, a spherical lens grating is often used. The spherical lens grating has a simple structure and low cost, making it suitable for large-scale production. However, in order to avoid image distortion, the spherical lens grating has a small aperture, resulting in low light output, which causes problems such as low resolution of the image and uneven view point distribution. Another related technology is to use an aspherical combined lens grating to replace the spherical lens grating. The aspherical combined lens grating can greatly reduce spherical aberration and chromatic aberration, ensuring the imaging quality of the image. However, the aspherical combined lens grating is very difficult to manufacture, has a low yield rate, and will significantly increase costs.

[0040] In the embodiment of the present application, three-dimensional imaging is achieved by setting a spherical lens, and the problem of spherical aberration and chromatic aberration is solved by combining a display screen 10 with an adjustable display area and a grating assembly 20 with an adjustable aperture size. In this way, the quality of the image can be improved without increasing costs. During actual use, the display area of the display screen 10 can be adjusted in coordination with the aperture size, thereby ensuring the image quality and realizing the experience of viewing a three-dimensional image with the naked eye.

[0041] Specifically, in the embodiment of the present application, the display screen 10 can be divided into two areas: a central display area 11 and an adjustable display area 12. The central display area 11 can be a constantly lit area that displays corresponding content. The adjustable display area 12 can be adjusted to be turned on or off at any time, which can supplement the light output while ensuring the display effect of the display device 100 and avoiding the problems of spherical aberration and chromatic aberration. The grating assembly 20 includes a light-transmitting area 22 and a shielding area 21. The light-transmitting area 22 can correspond to the central display area 11. After the central display area 11 emits light when displaying relevant content, it can emit light outward through the light-transmitting area 22. The central display area 11 can cover the light-transmitting area 22, that is, the area of the central display area 11 can be larger than the area of the light-transmitting area 22 to ensure the display effect and the integrity of the display. At the same time, the shielding area 21 can be aligned with and cover the adjustable display area 12 to define the size of the light-transmitting area 22, ensuring that the viewing angle of the display device 100 can be changed by adjusting the size of the light-transmitting area 22.

[0042] Furthermore, in the embodiments of the present application, the type of the display screen 10 is not limited. For example, the display screen 10 can be an Organic Light-Emitting Diode (OLED), which can emit light by itself and divide the display area into a central display area 11 and an adjustment display area 12. For another example, the display screen 10 can also be a Liquid Crystal Display (LCD), and the backlight layer of the LCD can be partitioned to correspond to the central display area 11 and the adjustment display area 12. In addition, in the embodiments of the present application, the type of the grating component 20 is not limited. The grating component 20 can be an LC baffle grating or an electrochromic baffle grating, as long as the requirements are met.

[0043] Please refer to Figure 4 , in some embodiments, the grating component 20 includes a first electrode layer 23, a color-changing layer 24, and a second electrode layer 25 arranged in sequence. The first electrode layer 23 is disposed close to the display screen 10, and the first electrode layer 23 and the second electrode layer 25 are used to apply a voltage to the color-changing layer 24.

[0044] In this way, the grating component 20 can form an electric field between the first electrode layer 23 and the second electrode layer 25 to cause the color-changing layer 24 to change color, thereby realizing the adjustment of the sizes of the light-transmitting area 22 and the shielding area 21.

[0045] Specifically, the electrode layer is a transparent electrode to avoid affecting the light output of the display area. At the same time, when an electric field is generated between the first electrode layer 23 and the second electrode layer 25, the color-changing layer 24 can be made black, and then a baffle grating can be formed. During the process of applying a voltage to cause the color-changing layer 24 to change color, the light-transmitting area 22 can be made smaller and the shielding layer can be made larger, that is, the opening of the grating component 20 becomes smaller. At the same time, the adjustment display area 12 can be controlled to cooperate with the central display area 11 to display relevant content, ensuring the light output while having a large viewing angle and avoiding the problem of spherical aberration focusing. In addition, when a large viewing angle is not required, the electrodes can be controlled not to apply a voltage to make the color-changing layer 24 in a transparent state, and the light-transmitting area 22 can be made larger and the shielding layer can be made smaller, that is, the opening of the grating component 20 becomes larger. At this time, the adjustment display area 12 of the closed part can be appropriately adjusted, thereby saving electric energy on the premise of ensuring the light output and display quality.

[0046] It can be understood that the display screen 10 is divided into a central display area 11 and an adjustment display area 12. The adjustment display area 12 can be appropriately turned off, which can save energy and reduce the frequency of use of the adjustment display area 12 to extend the display life of the display screen. At the same time, after the opening of the grating assembly 20 becomes smaller, the adjustment display area 12 cooperates with the central display area 11 to form a display unit to jointly display relevant content, so as to jointly emit light and increase the light output. Such an implementation method avoids the problem that when the opening of the grating assembly 20 is small, the central display area 11 has to increase the brightness to increase the light output, resulting in a reduction in the life of the display screen 10.

[0047] Please refer to Figure 4 , in some embodiments, the first electrode layer 23 is a planar electrode layer, the second electrode layer 25 is a strip-shaped electrode layer, and any two adjacent electrodes of the second electrode layer 25 are parallel and equally spaced.

[0048] In this way, the voltage required for the electrodes of the strip-shaped electrode layer is lower, saving electrical energy, and the color-changing layer 24 in the area between the strip-shaped electrodes can be a light-transmitting area 22 to ensure the external light output.

[0049] Specifically, in such an embodiment, the grating assembly 20 can use an electrochromic material as the color-changing layer 24. The first electrode layer 23 and the second electrode layer 25 can apply a voltage to the color-changing layer 24 to make it change color, and then the areas of the shielding area 21 and the light-transmitting area 22 can be changed. In one embodiment, the gap between any two adjacent electrodes of the second electrode layer 25 can be the middle part of the light-transmitting area 22. By applying a voltage to the strip-shaped electrodes, the color-changing layer 24 can form a shielding area 21, that is, the light-transmitting area 22 becomes smaller and the shielding area 21 becomes larger, and the opening of the grating assembly 20 becomes smaller. The second electrode layer 25 is a strip-shaped electrode, which ensures that the light-transmitting area 22 and the shielding area 21 can be separated. At the same time, the first electrode layer 23 is set as a planar electrode layer, that is, the entire surface of the first electrode layer 23 is an electrode, ensuring that the electrodes of the second electrode layer 25 can form a loop with the electrodes on the first electrode layer 23, and then an electric field can be applied to the color-changing layer 24. In addition, in some embodiments, the positions of the first electrode layer 23 and the second electrode layer 25 can be interchanged. That is, the strip-shaped electrode layer is arranged on the side of the color-changing layer 24 close to the display screen 10, and the planar electrode layer is arranged on the side of the color-changing layer 24 far from the display screen 10. The specific distribution method of the electrodes is not limited here. It only needs to ensure the distance between the grating assembly 20, the display screen 10 and the lens 30.

[0050] Please refer to Figure 5, in some embodiments, the grating assembly 20 further includes a third electrode layer 26. The third electrode layer 26 is disposed on a side of the second electrode layer 25 away from the color-changing layer 24. The third electrode layer 26 is a strip-shaped electrode layer, and the electrodes of the third electrode layer 26 are arranged in parallel with the electrodes of the second electrode layer 25. The electrodes of the third electrode layer 26 block the gaps between different electrodes of the second electrode layer 25.

[0051] In this way, the third electrode layer 26 can cooperate with the second electrode layer 25 to achieve zonal control of the color-changing layer 24, and can prevent the light of the display screen 10 from passing through the gaps between different electrodes of the second electrode layer 25 and affecting the display effect.

[0052] Further, please refer to Figure 5 , in some embodiments, the grating assembly 20 further includes an insulating layer 27. The insulating layer 27 is formed between the second electrode layer 25 and the third electrode layer 26.

[0053] In this way, the insulating layer 27 can isolate the second electrode layer 25 and the third electrode layer 26, and prevent the second electrode layer 25 and the third electrode layer 26 from affecting each other.

[0054] Specifically, any two adjacent electrodes of the third electrode layer 26 are distributed in parallel and at equal intervals, and at the same time, the electrodes of the second electrode layer 25 and the third electrode layer 26 can block each other's gaps, so as to prevent the light of the display screen 10 from passing through the gaps between adjacent electrodes during the light-shielding process of the color-changing layer 24 and affecting the display effect. In such an embodiment, the projections of the electrodes of the second electrode layer 25 and the third electrode layer 26 on the first electrode layer 23 can cover the first electrode layer 23, so as to ensure that the second electrode layer 25 and the third electrode layer 26 can cooperate with the first electrode layer 23 to form a grating that can completely shield the display screen 10.

[0055] In some embodiments, the electrodes of the third electrode layer 26 can also be arranged perpendicular to and cross the electrodes of the second electrode layer 25, and the gaps between the electrodes can be aligned with the central display area 11.

[0056] Please refer to Figure 1 , in some embodiments, the display device 100 further includes a lens 30. The lens 30 is disposed on a side of the grating assembly 20 away from the display screen 10, and the light-transmitting area 22 is aligned with the lens 30.

[0057] In this way, the lens 30 is disposed on the grating assembly 20, and the two-dimensional image emitted by the display screen 10 can achieve the effect of a three-dimensional picture after passing through the lens 30.

[0058] Specifically, the central position of the lens 30 can be aligned with the central positions of the light-transmitting area 22 and the central display area 11, thereby ensuring the display effect of the display device 100. Additionally, one lens 30 can cover multiple light-transmitting areas 22 and multiple central display areas 11, and the multiple display areas can jointly form multiple viewpoints in space. The number of light-transmitting areas 22 and central display areas 11 corresponding to one lens 30 is not limited herein, as long as the requirements are met.

[0059] Please refer to Figure 1 , in some embodiments, the display device 100 further includes a spacer layer 40, and the spacer layer 40 is disposed between the display screen 10 and the grating assembly 20.

[0060] In this way, the spacer layer 40 can prevent contact between the display screen 10 and the grating assembly 20, and at the same time, the spacer layer 40 can keep the distance between the display screen 10 and the grating assembly 20 constant.

[0061] Please refer to Figure 6 , the electronic device 200 according to the embodiment of the present application includes a camera 201 and the display device 100 according to any one of the above embodiments.

[0062] In the display device 100 and the electronic device 200 implemented in the present application, by controlling the sizes of the light-transmitting area 22 and the shielding area 21 through the grating assembly 20, the amount of light transmitted out by the display screen 10 can be changed. When a larger viewing angle is required, the light-transmitting area 22 can be adjusted to become smaller, and at the same time, the display area 12 is controlled to display relevant content to ensure the light output, thereby ensuring the imaging quality when there are more people. When a smaller viewing angle is required, the light-transmitting area 22 can be adjusted to become larger, and at the same time, the display area 12 is controlled to be turned off to reduce the light output, thereby saving electric energy on the premise of ensuring the imaging quality.

[0063] Please refer to Figure 7 and Figure 8 , the adjustment method according to the embodiment of the present application is used for the electronic device 200 according to the above embodiment, and the adjustment method includes:

[0064] S10, identifying the user's position through the camera 201;

[0065] S20, calculating the viewing angle range according to the user's position;

[0066] S30, adjusting the size of the light-transmitting area 22 according to the viewing angle range.

[0067] In the display device 100, electronic device 200, and adjustment method implemented in this application, by controlling the sizes of the light-transmitting area 22 and the shielding area 21 through the grating assembly 20, the amount of light transmitted outward by the display screen 10 can be changed. When a larger viewing angle is required, the light-transmitting area 22 can be adjusted to become smaller, and at the same time, the display area 12 is controlled and adjusted to display relevant content to ensure the light output, thereby ensuring the imaging quality when there are more people. When a smaller viewing angle is required, the light-transmitting area 22 can be adjusted to become larger, and at the same time, the display area 12 is controlled and adjusted to turn off to reduce the light output, thereby saving electric energy on the premise of ensuring the imaging quality.

[0068] In the electronic device 200 according to an embodiment of the present application, the electronic device 200 further includes a processor 202 and a memory 203. The processor 202 and the memory 203 are electrically connected, and the processor 202 is also electrically connected to the display device 100 and the camera 201 respectively. Among them, the processor 202 is used to execute the computer program stored in the memory 203 to execute the control method according to an embodiment of the present application. That is to say, the above steps S10 - S30 can all be executed by the processor 202, that is, the processor 202 can be used to identify the user's position through the camera 201; and used to calculate the viewing range according to the user's position; and also used to adjust the size of the light-transmitting area 22 according to the viewing range.

[0069] Specifically, the electronic device 200 can be viewed by multiple users at the same time. The electronic device 200 can control the position of the users through the camera 201, and then the activity range of the users can be calculated. The sum of the activity ranges of the users on the left and right sides is the viewing range of multiple users, that is, the maximum left and right viewing angles. Then the electronic device 200 can control and adjust the grating assembly 20 through the processor 202, and then the sizes of the light-transmitting area 22 and the shielding area 21 can be adjusted. It should be noted that during the use of the electronic device 200 or the display device 100 by the user, the body will move to a certain extent. That is to say, during the calculation of the viewing range, the moving interval of the user needs to be included, that is, on the basis of the activity ranges of the users on the left and right sides, a certain visible angle is added to ensure that the user can have a better experience within the viewing range.

[0070] Please refer to Figure 7 and Figure 9 , in some embodiments, the adjustment method includes:

[0071] S40, controlling and adjusting the display area 12 according to the viewing range.

[0072] In this way, while controlling the size of the light-transmitting area 22, the electronic device 200 can control and adjust the brightness and darkness of the display area 12, thereby realizing the adjustment of different viewing range sizes and ensuring good display effects for both large and small viewing angles.

[0073] In the electronic device 200 according to the embodiment of the present application, the above-mentioned step S40 can be executed by the processor 202, that is, the processor 202 can be used to control and adjust the display area 12 according to the viewing range.

[0074] Exemplarily, when the electronic device 200 is started, the processor 202 of the electronic device 200 can perform face recognition on the viewing area by using the camera 201 and calculate the viewing angle of the viewing person in real time, adjust the opening position and size of the baffle grating assembly 20 according to the current viewing angle, and at the same time match the sub-pixels corresponding to the display screen 10 in real time to display the corresponding viewing area content and corresponding brightness. Then, the power consumption of the naked-eye stereoscopic display source can be adjusted in real time according to the position of the viewing person, so as to achieve the purpose of reducing power consumption.
