[0040] In order to make the objects, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the range of the present disclosure.

[0041] Unless otherwise defined, technical terms or scientific terms used in the present disclosure should be understood as having the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. The terms “first”, “second”, and similar terms used in the present disclosure do not denote any order, quantity, or importance, but are used to distinguish different components. The terms “include”, “contain”, and similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects.

[0042] The terms “same” and similar terms used in the present disclosure include the strict “same” and similar terms with certain errors, which, considering the measurement and the error related to the measurement of a specific value (that is, the limitation of the measurement system), represent the acceptable deviation range for the specific value determined by a person of ordinary skill in the art.

[0043] With the development of transparent display technology, the transparent display technology is more and more widely applied in commercial display and vehicle display. In commercial display, the transparent display screen can show the product information selected by the customer to the customers in the store, and can play the advertising information of the store or brand outside the store, so as to maximize the use of limited space to spread more information of goods or brands, which is beneficial to realize commercial display promotion.

[0044] In vehicle display, the transparent display screen can provide content display to the driver or passenger during vehicle driving, such as realizing vehicle office and vehicle entertainment. The transparent display screen can also realize the interaction between the driver and the driver of other vehicles, the passenger of other vehicles or pedestrians, and improve the added value of the vehicle.

[0045] In the research, the inventors of the present application found that when the external light is relatively bright, the real scene superimposed on the display image of the transparent display screen will cause visual interference, resulting in poor display effect. For this purpose, the background transmittance of the transparent display screen can be dynamically adjusted by using the dimming glass to improve the transparent display effect, but the energy consumption is high during the dynamic adjustment of the dimming glass.

[0046] The transparent display module provided by at least one embodiment of the present disclosure comprises: a display screen comprising a first display surface and a second display surface arranged oppositely; a dimming assembly comprising a first dimming piece and a second dimming piece; the first dimming piece is arranged on the side of the first display surface away from the second display surface, and the second dimming piece is arranged on the side of the second display surface away from the first display surface; wherein the transmittance of the dimming area of the first dimming piece is different from the transmittance of the dimming area of the second dimming piece in the power-off state of the dimming assembly; and the orthographic projection of the dimming area of the first dimming piece and the orthographic projection of the dimming area of the second dimming piece at least partially overlap on the first display surface.

[0047] The vehicle window provided by at least one embodiment of the present disclosure comprises the above-mentioned transparent display module.

[0048] The vehicle provided by at least one embodiment of the present disclosure comprises the above-mentioned vehicle window.

[0049] The transparent display module, vehicle window and vehicle provided by the embodiments of the present disclosure have different transmittances of the dimming area of the first dimming piece and the dimming area of the second dimming piece, so that in the power-off state of the dimming assembly, one of the dimming area of the first dimming piece and the dimming area of the second dimming piece has a higher transmittance, and the other has a lower transmittance. Therefore, without power supply, the user can watch on the side with higher transmittance, thereby achieving better viewing effect while saving energy consumption.

[0050] The control method of the light-adjusting module provided in the embodiments of the present disclosure can determine a viewing surface according to the running state of the vehicle or the viewing position of the user, and then determine whether the light-adjusting component needs to be powered on based on the viewing surface. Since the light-adjusting area of the first light-adjusting piece and the light-adjusting area of the second light-adjusting piece have different light transmittances, the user can watch on the side with higher light transmittance without the need of powering on, thereby achieving better viewing effect and saving energy consumption.

[0051] The control method of the light-adjusting module provided in the embodiments of the present disclosure can determine a viewing surface according to the running state of the vehicle or the viewing position of the user, and then determine whether the light-adjusting component needs to be powered on based on the viewing surface. Since the light-adjusting area of the first light-adjusting piece and the light-adjusting area of the second light-adjusting piece have different light transmittances, the user can watch on the side with higher light transmittance without the need of powering on, thereby achieving better viewing effect and saving energy consumption.

[0052] The light-adjusting module, the control method thereof, the vehicle window and the vehicle will be described below in combination with the accompanying drawings and some embodiments.

[0053] FIG. 1 is a schematic view of the light-adjusting module in a powered-off state according to an embodiment of the present disclosure; and FIG. 2 is a schematic view of the light-adjusting module in a powered-on state according to an embodiment of the present disclosure.

[0054] Referring to FIGS. 1 and 2, the light-adjusting module includes a display screen 100 and a light-adjusting component 200. For example, the display screen 100 is a transparent display screen. For example, the transparent display screen can be an Organic Light-emitting Diode (OLED) transparent screen, a Light-emitting Diode (LED) transparent screen or a Liquid Crystal Display (LCD) transparent screen.

[0055] Referring to FIGS. 1 and 2, the display screen 100 includes a first display surface 101 and a second display surface 102 arranged oppositely. For example, the display screen can be provided as one, and the first display surface and the second display surface are two surfaces of the one display screen arranged oppositely. The first display surface and the second display surface can display simultaneously or display in time division. The first display surface and the second display surface can display the same frame of picture or different frames of picture. For example, the display screen can be provided as a plurality of display screens. For example, the display screen is provided as two, and the first display surface and the second display surface can display simultaneously or display in time division. The first display surface and the second display surface can be two surfaces of the two display screens respectively. The first display surface and the second display surface can display the same frame of picture or different frames of picture.

[0056] Referring to FIG. 1 and FIG. 2, the light modulation assembly 200 includes a first light modulation piece 210 and a second light modulation piece 220. The first light modulation piece 210 is disposed on a side of the first display surface 101 away from the second display surface 102, and the second light modulation piece 220 is disposed on a side of the second display surface 102 away from the first display surface 101. For example, the first light modulation piece 210 and the second light modulation piece 220 can be electrically controlled light modulation glass. For example, referring to FIG. 1 and FIG. 2, the first light modulation piece 210 and the second light modulation piece 220 can adjust the light transmittance by adjusting the input voltage.

[0057] Referring to FIG. 1, in the power-off state, the light transmittance of the light modulation area 210a of the first light modulation piece 210 is different from the light transmittance of the light modulation area 220a of the second light modulation piece 220. For example, the light modulation area 210a of the first light modulation piece 210 can be a partial area or the entire area of the first light modulation piece 210. For example, the light modulation area 220a of the second light modulation piece 220 can be a partial area or the entire area of the second light modulation piece 220.

[0058] Referring to FIG. 1, for example, the light modulation piece (for example, at least one of the first light modulation piece 210 and the second light modulation piece 220) includes a liquid crystal layer, and the arrangement state of the liquid crystal molecules in the liquid crystal layer can change with the change of the electric field, so that the light transmittance of the light modulation area of the light modulation piece changes, thereby the light modulation piece can switch between the dark state and the bright state. For example, in the power-off state, the first light modulation piece 210 can be in the dark state (for example, the first light modulation piece is in the normally black state), and the second light modulation piece 220 can be in the bright state (for example, the second light modulation piece is in the normally white state), so that the light modulation area of the first light modulation piece 210 and the light modulation area of the second light modulation piece 220 have different light transmittances.

[0059] FIG. 3 is a schematic diagram of the orthographic projection of the light modulation area of the first light modulation piece and the light modulation area of the second light modulation piece on the first display surface in the light modulation assembly shown in FIG. 1.

[0060] Referring to FIGS. 1-3, on the first display surface 101, the orthographic projection P1 of the light-adjusting area 210a of the first light-adjusting piece 210 and the orthographic projection P2 of the light-adjusting area 220a of the second light-adjusting piece 220 at least partially overlap. For example, the orthographic projection P1 of the light-adjusting area 210a of the first light-adjusting piece 210 and the orthographic projection P2 of the light-adjusting area 220a of the second light-adjusting piece 220 can partially overlap or completely overlap. FIG. 3 schematically shows that the areas of the orthographic projection P1 of the light-adjusting area 210a of the first light-adjusting piece 210 and the orthographic projection P2 of the light-adjusting area 220a of the second light-adjusting piece 220 are both smaller than the first display surface 101. However, the present disclosure is not limited thereto, and the area of the orthographic projection of the light-adjusting area of the first light-adjusting piece can also be equal to the area of the first display surface, or the area of the orthographic projection of the light-adjusting area of the first light-adjusting piece can also be greater than the area of the first display surface. Accordingly, the area of the orthographic projection of the light-adjusting area of the second light-adjusting piece can also be equal to or greater than the area of the first display surface, and the present disclosure does not limit this.

[0061] Referring to FIGS. 1-3, the light-adjusting module provided by the embodiments of the present disclosure has different light transmittances of the light-adjusting area 210a of the first light-adjusting piece 210 and the light-adjusting area 220a of the second light-adjusting piece 220, so that in the power-off state, one of the light-adjusting area 210a of the first light-adjusting piece 210 and the light-adjusting area 220a of the second light-adjusting piece 220 has a higher light transmittance, and the other has a lower light transmittance. Thus, without power, the user can be facilitated to view on the side with the higher light transmittance, thereby achieving better viewing effect while saving energy. For example, when the light-adjusting area 210a of the first light-adjusting piece 210 has a higher light transmittance, the light-adjusting area 220a of the second light-adjusting piece 220 has a lower light transmittance, thereby facilitating the user to view the first display surface 101. For example, when the light-adjusting area of the second light-adjusting piece 220 has a higher light transmittance, the light-adjusting area of the first light-adjusting piece 210 has a lower light transmittance, thereby facilitating the user to view the second display surface 102.

[0062] For example, the thickness of the display screen can be about 1 millimeter, the thickness of the light-adjusting piece in the dark state in the power-off state can be about 0.76 millimeter, and the thickness of the light-adjusting piece in the bright state in the power-off state can be about 1 millimeter. However, the present disclosure is not limited thereto, and the thickness of the display screen and the light-adjusting piece can also be thicker or thinner.

[0063] Referring to FIGS. 1 and 2, in some examples, the light-adjusting assembly 200 is in a powered-on state, when the intensity of the electric field reaches a preset intensity, at least one of the light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 and the light transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 changes, so that the light transmittance can be changed according to the user's needs, so that the user can achieve a better viewing effect when viewing the first display surface 101 and the second display surface 102, and the overall display effect is improved. For example, when the light-adjusting module is applied to a vehicle, by adjusting the light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 and the light-adjusting area 220a of the second light-adjusting piece 220, it is beneficial to serve the people inside and outside the vehicle, and enriches the display function of transparent display. For example, when the voltage is increased to a certain voltage value, the electric field intensity reaches the preset intensity, and further increasing the voltage can change the light transmittance of the light-adjusting piece. For example, when the voltage reaches 9V-15V, the electric field intensity reaches the preset intensity.

[0064] Referring to FIGS. 1 and 2, for example, when the light-adjusting assembly 200 is in a powered-off state and the light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 is low, in order to improve the viewing effect of the first display surface 101, the light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 can be increased by being powered on. For example, when the light-adjusting assembly 200 is in a powered-off state and the light transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 is high, in order to improve privacy, the light transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 can be reduced by being powered on.

[0065] For example, in the case that the light-adjusting assembly is powered on and the electric field intensity does not reach the preset intensity, the light transmittance of the light-adjusting area of the first light-adjusting piece and the light transmittance of the light-adjusting area of the second light-adjusting piece do not change. Referring to FIGS. 1 and 2, for example, when the intensity of the electric field reaches the preset intensity, the light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 and the light transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 can change with the change of the electric field intensity.

[0066] Referring to FIGS. 1 and 2, in some examples, the first light-adjusting piece 210 is configured to, under the action of an electric field, the light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 increases with the increase of the intensity of the electric field. For example, the first light-adjusting piece is powered on, so that the first light-adjusting piece can be subjected to the action of the electric field. For example, with the increase of the intensity of the electric field, the change range of the light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 can be 1%-30%. For example, the light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 can be 5%-25%. For example, the light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 can be 10%-20%. For example, the light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 can be 15%.

[0067] Referring to FIGS. 1 and 2, in some examples, the second light-adjusting piece 220 is configured to have a light transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 decreasing with an increase of intensity of the electric field under the action of the electric field. For example, the second light-adjusting piece is powered to enable the second light-adjusting piece to be subjected to the action of the electric field. For example, the light-adjusting area 220a of the second light-adjusting piece 220 can have a light transmittance ranging from 28% to 0.7% with the increase of the intensity of the electric field. For example, the light-adjusting area 220a of the second light-adjusting piece 220 can have a light transmittance ranging from 1% to 25%. For example, the light-adjusting area 220a of the second light-adjusting piece 220 can have a light transmittance ranging from 10% to 20%. For example, the light-adjusting area 220a of the second light-adjusting piece 220 can have a light transmittance of 15%.

[0068] However, the present disclosure is not limited thereto. For example, the light-adjusting area of the first light-adjusting piece can have a light transmittance ranging from 0.8% to 35%. For example, the light-adjusting area of the second light-adjusting piece can have a light transmittance ranging from 0.5% to 30%. For example, the light-adjusting area of the second light-adjusting piece can have a light transmittance ranging from 1% to 38%. Of course, the light-adjusting area of the first light-adjusting piece and the light-adjusting area of the second light-adjusting piece can also be adjusted as needed. For example, at least one of the first light-adjusting piece and the second light-adjusting piece can also be an electrochromic light-adjusting piece, and the light-adjusting area can have a light transmittance ranging from 1% to 65%.

[0069] Referring to FIG. 1, in some examples, the light-adjusting assembly 200 has a light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 being less than a light transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 in a power-off state. For example, the light-adjusting assembly 200 has the first light-adjusting piece 210 in a dark state and the second light-adjusting piece 220 in a bright state in the power-off state.

[0070] Referring to FIGS. 1 and 2, in some examples, the light-adjusting assembly 200 has a light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 being a first light transmittance and a light transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 being a second light transmittance in a power-on state. The light-adjusting assembly 200 has a light transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 being a third light transmittance and a light transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 being a fourth light transmittance in a power-off state. The third light transmittance is less than the first light transmittance, and the fourth light transmittance is greater than the second light transmittance. For example, the light-adjusting area 210a of the first light-adjusting piece 210 has an increased light transmittance after being powered on, and the light-adjusting area 220a of the second light-adjusting piece 220 has a decreased light transmittance after being powered on, compared with the power-off state.

[0071] Referring to FIGS. 1 and 2, in some examples, the light-adjusting assembly is used in a vehicle. One of the first light-adjusting piece 210 and the second light-adjusting piece 220 is located on a side of the display screen 100 facing the interior of the vehicle, and the other is located on a side of the display screen 100 facing the exterior of the vehicle.

[0072] For example, when the first light-adjusting part is in a dark state and arranged on the inside of the vehicle in the power-off state, the display screen is displayed to the outside of the vehicle in the power-off state, so as to save energy. For example, the first light-adjusting part in the dark state is arranged on the side facing the inside of the vehicle in the power-off state, and the power supply of the light-adjusting assembly is turned off when the vehicle is turned off. In the power-off state, the display screen is inclined to be displayed to the outside. The display screen can be powered on, so that the display information such as commercial advertisements can be displayed to the user outside the vehicle on the basis of saving energy as much as possible, and the information that can be interacted with the driver or the passenger can also be displayed to the user outside the vehicle. For example, in the vehicle scene, the time of the vehicle turned off is much longer than the time of the vehicle turned on, and thus the display to the outside is inclined to serve the user outside the vehicle with lower display energy consumption, so that the user outside the vehicle can clearly see the content displayed on the display screen.

[0073] For example, when the first light-adjusting part is in a dark state and arranged on the outside of the vehicle in the power-off state, the display screen is displayed to the inside of the vehicle in the power-off state, for example, to display commercial advertisements or office information, so as to save energy. For example, the first light-adjusting part in the dark state is arranged on the side facing the outside of the vehicle in the power-off state, and is inclined to be displayed to the inside in the power-off state. The display screen can provide the display content such as navigation information and entertainment information to the driver and the passenger in the vehicle on the basis of saving energy as much as possible, and can also be used for business vehicle office to improve the added value of the vehicle.

[0074] FIG. 4 is a schematic diagram of a light-adjusting module provided by an example in at least one embodiment of the present disclosure.

[0075] Referring to FIG. 4, in some examples, the light-adjusting area 210a of the first light-adjusting part 210 includes a first area A1 and a second area A2, and the light-adjusting area 220a of the second light-adjusting part 220 includes a third area A3 and a fourth area A4. For example, the first area A1 and the second area A2 are adjacent to each other, and no other area is arranged between the first area A1 and the second area A2. For example, the third area A3 and the fourth area A4 are adjacent to each other, and no other area is arranged between the third area A3 and the fourth area A4. On the first display surface 101, the orthographic projection of the first area A1 and the orthographic projection of the third area A3 overlap, and the orthographic projection of the second area A2 and the orthographic projection of the fourth area A4 overlap, so that the first area A1 and the third area A3 are opposite to each other, and the second area A2 and the fourth area A4 are opposite to each other. For example, the orthographic projection of the first area A1 and the orthographic projection of the third area A3 can partially overlap or completely overlap. For example, the orthographic projection of the second area A2 and the orthographic projection of the fourth area A4 can partially overlap or completely overlap.

[0076] For example, the first area, the second area, the third area and the fourth area described above can be multiple light modulation units with different light transmittances physically spliced together, or can be areas with different light transmittances by applying different voltages to different areas through circuit design, and the present disclosure does not limit this. For example, communication can be achieved between areas through such as circuit design or algorithm design, so as to achieve the effect of linkage.

[0077] Referring to FIG. 4, for example, the first display surface 101 of the display screen 100 can include a first display area 101a, and the second display surface 102 can include a second display area 102a. The orthographic projection of the first display area 101a on the second display surface 102 can at least partially not fall into the second display area 102a, so that the first display area 101a and the second display area 102a can display different pictures without interfering with each other.

[0078] FIGS. 5A and 5B are schematic diagrams of the first area and the second area provided by different examples in at least one embodiment of the present disclosure.

[0079] For example, referring to FIG. 5A, the first area A1 and the second area A2 can be adjacent in the up-down direction, and referring to FIG. 5B, the first area A1 and the second area A2 can be adjacent in the left-right direction. For example, the up-down direction refers to the up-down direction shown in FIG. 5A, which can be the up-down direction relative to the ground, for example. For example, the left-right direction refers to the left-right direction shown in FIG. 5B, which can be the front-rear direction relative to the vehicle body, for example. For example, similar to the arrangement position relationship between the first area A1 and the second area A2 shown in FIGS. 5A and 5B, the third area and the fourth area can be adjacent in the up-down direction or in the left-right direction. However, the present disclosure is not limited thereto, and the arrangement direction of the first area and the second area and the arrangement direction of the third area and the fourth area can also be other directions. For example, the first area can be only one area, or can include multiple sub-areas. For example, the second area can be only one area, or can include multiple sub-areas. For example, the third area can be only one area, or can include multiple sub-areas. For example, the fourth area can be only one area, or can include multiple sub-areas.

[0080] Referring to FIG. 4, in the power-off state, the light transmittance of the first area A1 is greater than that of the third area A3, and the light transmittance of the second area A2 is less than that of the fourth area A4. Thus, the first display surface 101 can be viewed favorably from the side where the first area A1 is located, and the second display surface 102 can be viewed favorably from the fourth area A4 located on the other side. Thus, by zoning the first light modulation member 210 and the second light modulation member 220 to modulate light, the user can view from both sides of the light modulation module. For example, the display screen can be displayed in zones (e.g., the first display area 101a and the second display area 102a shown in FIG. 4), and the image displayed in the area corresponding to the first area and the third area is different from the image displayed in the area corresponding to the second area and the fourth area.

[0081] Referring to FIG. 4, in some examples, in the power-on state, when the intensity of the electric field reaches a preset intensity, the light modulation assembly 200 is configured to satisfy at least one of the following conditions: the first light modulation member 210 is configured to, under the action of the electric field, the light transmittance of the first area A1 decreases as the intensity of the electric field increases, and the light transmittance of the second area A2 increases as the intensity of the electric field increases. The second light modulation member 220 is configured to, under the action of the electric field, the light transmittance of the third area A3 increases as the intensity of the electric field increases, and the light transmittance of the fourth area A4 decreases as the intensity of the electric field increases.

[0082] Referring to FIG. 4, for example, the second area A2 of the first light modulation member 210 and the third area A3 of the second light modulation member 220 are in a dark state in the power-off state, so that as the intensity of the electric field increases, the light transmittance increases to switch the second area A2 and the third area A3 from the dark state to the bright state. For example, the first area A1 of the first light modulation member 210 and the fourth area A4 of the second light modulation member 220 are in a bright state in the power-off state, so that as the intensity of the electric field increases, the light transmittance increases to switch the first area A1 and the fourth area A4 from the bright state to the dark state. Thus, when the light modulation assembly 200 is in the power-off state, the user can view the first display surface 101 from the first area A1 of the first light modulation member 210, and the user can view the second display surface 102 from the fourth area A4 of the second light modulation member 220. In addition, only the area that needs to adjust the light transmittance can be powered on to adjust the light transmittance of each area, which is conducive to saving energy and meeting the different needs of users.

[0083] FIG. 6 is a schematic diagram of a light modulation module provided by an example in at least one embodiment of the present disclosure.

[0084] Referring to FIG. 6, in some examples, the dimming assembly 200 is in a power-off state, and the display screen 100 is in a non-working state, the first area A1 reaches the maximum light transmittance of the first area A1, the second area A2 reaches the minimum light transmittance of the second area A2, the third area A3 reaches the maximum light transmittance of the third area A3, and the fourth area A4 reaches the minimum light transmittance of the fourth area A4. When the display screen 100 is in the non-working state, neither the first display surface 101 nor the second display surface 102 displays a picture, and the dimming module can act as ordinary glass to facilitate the user to view the external scene.

[0085] It can be understood that the maximum light transmittance and the minimum light transmittance refer to the light transmittance in the power-on state or the power-off state. Taking the first area in the bright state in the power-off state as an example, the first area reaches the maximum light transmittance when the first area of the first dimming piece is powered off, and reaches the minimum light transmittance after the first area is powered on and reaches the preset intensity of the electric field. It can be understood that when the first area is under the action of the electric field, the light transmittance of the first area increases as the intensity of the electric field decreases (does not decrease below the preset intensity of the electric field), and reaches the maximum light transmittance when the intensity decreases to the preset intensity of the electric field.

[0086] Referring to FIG. 6, for example, the dimming assembly 200 is in a power-off state, the corresponding first area A1 and third area A3 are in a bright state, and the corresponding second area A2 and fourth area A4 are in a dark state, and the scene inside and outside the vehicle can be viewed through the first area A1 and the third area A3. For example, when the dimming assembly 200 is not powered on, the driver can observe the environment outside the vehicle through the first area A1 and the third area A3 which are both in the bright state, and improve the privacy inside the vehicle through the second area A2 and the fourth area A4 which are both in the dark state.

[0087] FIG. 7 is a schematic diagram of a dimming module provided in an example of at least one embodiment of the present disclosure, and FIG. 8 is a schematic block diagram of the dimming module shown in FIG. 7.

[0088] Referring to FIGS. 7 and 8, in some examples, the dimming module further includes a controller 300, a first touch screen 410, and a second touch screen 420. The first touch screen 410, the first dimming piece 210, the second touch screen 420, the second dimming piece 220, and the display screen 100 are electrically connected to the controller 300. The first touch screen 410 is arranged on the side of the first dimming piece 210 away from the first display surface 101, and the second touch screen 420 is arranged on the side of the second dimming piece 220 away from the second display surface 102, so that the user can use the first touch screen 410 and the second touch screen 420 to realize touch control of the first dimming piece 210, the second dimming piece 220, and the display screen 100. In addition, the first touch screen 410 and the second touch screen 420 are arranged on the two sides of the first dimming piece 210 and the second dimming piece 220, respectively, so that the dimming module can be controlled from both sides of the dimming module.

[0089] Referring to FIGS. 7 and 8, in some examples, the dimming module can only include the controller 300 and the first touch screen 410. The first touch screen 410, the first dimming piece 210, the second dimming piece 220, and the display screen 100 are electrically connected with the controller 300, respectively. The first touch screen 410 is arranged on the side of the first dimming piece 210 away from the first display surface 101, so that the user can use the first touch screen 410 to realize touch control of the first dimming piece 210 and the display screen 100. In addition, arranging the first touch screen 410 on the side of the first dimming piece 210 away from the first display surface 101 can realize control of the dimming module from a single side of the dimming module. Of course, the dimming module can also only arrange the second touch screen 420 on the side of the second dimming piece 220 away from the second display surface 102, so that the dimming module realizes touch control only through the second touch screen 420, which is not limited in the present disclosure.

[0090] Referring to FIGS. 7 and 8, the dimming module is configured to satisfy at least one of the following conditions: the controller 300 is configured to send a first control signal to the display screen 100 to make the display screen 100 display based on a first touch control signal sent by the first touch screen 410. The controller 300 is configured to send a second control signal to the dimming assembly 200 to change at least one of the light transmittance of the light modulation area 210a of the first dimming piece 210 and the light transmittance of the light modulation area 220a of the second dimming piece 220 based on a second touch control signal sent by the first touch screen 410. The controller 300 is configured to send a third control signal to the display screen 100 to make the display screen 100 display based on a third touch control signal sent by the second touch screen 420. The controller 300 is configured to send a fourth control signal to the dimming assembly 200 to change at least one of the light transmittance of the light modulation area 210a of the first dimming piece 210 and the light transmittance of the light modulation area 220a of the second dimming piece 220 based on a fourth touch control signal sent by the second touch screen 420.

[0091] Referring to FIGS. 7 and 8, for example, through touch control operations on the first touch screen 410 and the second touch screen 420, the display screen 100 can be controlled to display the picture required by the user, and the display screen 100 can also be controlled to switch between the working state and the non-working state. For example, through touch control operations on the first touch screen 410 and the second touch screen 420, the light transmittance of the dimming assembly 200 can be changed as needed. For example, only the light transmittance of the light modulation area 210a of the first dimming piece 210 can be changed, only the light transmittance of the light modulation area 220a of the second dimming piece 220 can be changed, or the light transmittance of the light modulation area 210a of the first dimming piece 210 can be changed while the light transmittance of the light modulation area 220a of the second dimming piece 220 is changed.

[0092] FIG. 9 is a schematic diagram of a dimming module according to an example of at least one embodiment of the present disclosure. FIG. 10 is a schematic block diagram of a dimming module according to an example of at least one embodiment of the present disclosure.

[0093] Referring to FIG. 9, for example, the dimming module can include two display screens 10 and a dimming piece 20, and the two display screens 10 are respectively arranged on opposite sides of the dimming piece 20. The dimming piece 20 has a minimum light transmittance in a power-off state, for example, in a dark state (normally black state). For example, when display is needed inside the vehicle, only the display screen 10 on the side of the dimming piece 20 close to the inside of the vehicle can be turned on for display, while the dimming piece 20 remains powered off. For example, when display is needed outside the vehicle, only the display screen 10 on the side of the dimming piece 20 close to the outside of the vehicle can be turned on for display, while the dimming piece 20 remains powered off. For example, when display is needed from both the inside and outside of the vehicle, both display screens 10 can be turned on, and the dimming piece 20 remains powered off.

[0094] Referring to FIG. 9, for example, the dimming piece 20 can have a light transmittance ranging from 1% to 30%. In this way, the two display screens 10 can display different images respectively, and the dimming piece 20 in a dark state when powered off can improve the display effect of the two display screens 10, while preventing the images displayed by the two display screens 10 from interfering with each other. For example, both display screens 10 can display fog images to improve the shading effect. For example, when the dimming module is used as ordinary glass, the dimming piece 20 can be powered on to increase the light transmittance of the dimming piece 20, thereby increasing the light transmittance of the dimming module, and at this time, both display screens 10 can be in a non-working state, but the present disclosure is not limited thereto.

[0095] Referring to FIGS. 9 and 10, for example, the dimming module can further include a first touch screen 31 and a second touch screen 32, and the first touch screen 31 and the second touch screen 32 are respectively located on the side of the two display screens 10 away from the dimming piece 20. The dimming module can further include a controller 40. The first touch screen 31 and the second touch screen 32 can send touch driving signals to the controller 40, the controller 40 can send display driving signals to the two display screens 10 respectively to realize display, and the controller 40 can also send dimming driving signals to the dimming piece 20. In this way, the dimming module can realize user control of the two display screens 10 and the dimming piece 20 through the first touch screen 31 and the second touch screen 32.

[0096] FIG. 11 is a schematic diagram of a dimming module according to an example of at least one embodiment of the present disclosure.

[0097] Referring to FIG. 11, for example, the dimming module can include the dimming piece 01 and the display screen 02 located on one side of the dimming piece 01, thereby reducing the thickness of the dimming module. For example, the dimming piece 01 reaches the minimum light transmittance in the power-off state, for example, in the dark state (common black state), to achieve privacy protection when the vehicle is started or turned off. For example, the power of the dimming piece 01 is turned off after the vehicle is turned off, so that the dimming piece 01 is in the power-off state. For example, when the vehicle is started (for example, during driving), the dimming piece 01 can be in the power-off state to start the privacy protection function, and the dimming piece 01 can also be in the power-on state to improve the light transmittance of the dimming module.

[0098] Referring to FIG. 11, for example, the dimming piece 01 in the dark state in the power-off state is located on the inside of the vehicle, and the display screen 02 can tend to display outwardly, and display outwardly in the case of saving energy. For example, the dimming piece 01 in the dark state in the power-off state is located on the outside of the vehicle, and the display screen 02 can tend to display inwardly, and display inwardly in the case of saving energy.

[0099] Referring to FIG. 11, for example, the dimming piece 01 reaches the maximum light transmittance in the power-off state, for example, in the bright state (common white state), to improve the light transmittance of the dimming module. For example, the power of the dimming piece 01 is turned off after the vehicle is turned off, so that the dimming piece 01 is in the power-off state. For example, when the vehicle is started, the dimming piece 01 can be powered off, or the dimming piece 01 can be powered on to reduce the light transmittance of the dimming module to improve the display effect of the display screen 02. For example, the dimming piece 01 in the bright state in the power-off state is located on the inside of the vehicle, and the dimming piece 01 can be powered on to reduce the light transmittance of the inside dimming piece 01 to facilitate outward display. For example, the dimming piece 01 in the bright state in the power-off state is located on the outside of the vehicle, and the dimming piece 01 can be powered on to reduce the light transmittance of the outside dimming piece 01 to facilitate inward display.

[0100] The vehicle window provided by at least one embodiment of the present disclosure includes the dimming module described above. For example, the vehicle window can include a front window, a side window, a sunroof, a rear window, and a door window, and can also include other vehicle windows. Since the dimming module according to the embodiments of the present disclosure is used in the above-mentioned vehicle window, it also has corresponding beneficial technical effects, which are not described here.

[0101] In some examples, the vehicle window (automobile glass) can be composed of laminated glass, soundproof film and glass, which is also called laminated glass. The soundproof film is, for example, a PolyVinyl Butyral (PVB) film, which can also be referred to as a PVB interlayer. Such a vehicle window can combine the toughness of the PVB interlayer and the hardness of the glass, thereby enhancing the anti-penetration ability of the glass while effectively preventing the glass fragments from splashing and injuring people. For example, the front window (front windshield) is a special vehicle window among all the vehicle windows, which has strict requirements on safety and vision. Therefore, the front window can be a vehicle window with a laminated glass structure, so that the broken glass will not splash and threaten the safety of the driver or passengers after the glass is broken.

[0102] In order to ensure the safety and durability of the vehicle window in different environments, the thickness of the vehicle window usually has the following standards.

[0103] The thickness of the front window can be 4.76 mm to 6.35 mm. For example, in the front window with a laminated glass structure, the thickness of the two pieces of glass can each be 2 mm, and the thickness of the soundproof film can be 0.76 mm, so that the total thickness of the front window is 4.76 mm. For example, the thickness of the two pieces of glass can each be 2.5 mm, and the thickness of the soundproof film can be 0.76 mm, so that the total thickness of the front window is 5.76 mm. However, the present disclosure is not limited thereto, for example, when the light modulation module in the embodiment of the present disclosure is included in the front window, the total thickness can be thicker.

[0104] The thickness of the rear window can be 3.5 mm. However, the present disclosure is not limited thereto, for example, when the light modulation module in the embodiment of the present disclosure is included in the rear window, the total thickness can be thicker. The rear window (rear windshield) also usually needs good properties. For example, the glass of the rear window can be treated by a chemical or physical treatment method, for example, the glass of the rear window can be tempered glass bonded by high temperature and high pressure, thereby improving the mechanical strength and thermal stability of the rear window, so that the rear window has the properties of wind pressure resistance and impact resistance. The rear window can be integrated with an antenna instead of a pull rod type antenna, so that the antenna does not need to be pulled in and out when in use. The rear window can also be integrated with a heating wire, which can make the surface temperature of the glass reach between 40°C and 75°C after being powered on, so that the frost and fog condensed on the surface of the rear window can be removed in cold winter.

[0105] The thickness of the side window can be not less than 3 mm. However, the present disclosure is not limited thereto, for example, when the light modulation module in the embodiment of the present disclosure is included in the side window, the total thickness can be thicker. For example, the thickness of the side window can be 3.18 mm to 4.76 mm. Of course, the thickness of the side window can be thicker, and the present disclosure does not limit this.

[0106] It should be noted that the thickness standard of the vehicle window will be different according to different use environments, such as tropical regions, cold regions, and plateau regions. For example, in the tropical region, the thickness of the front window of the vehicle is not less than 6 mm, and in the plateau region, the thickness of the side window is not less than 4 mm.

[0107] The vehicle according to the embodiments of the present disclosure includes the vehicle window described above. Therefore, the vehicle also has the corresponding beneficial technical effects, which will not be repeated here.

[0108] FIG. 12 is a flowchart of a control method of the light modulation module according to an embodiment of the present disclosure.

[0109] Referring to FIGS. 1, 2, and 12, the control method of the light modulation module according to an embodiment of the present disclosure is provided for a vehicle, and the method includes the following steps S110 and S120.

[0110] Step S110: determining at least one of the first display surface 101 and the second display surface 102 as a viewing surface based on the running state of the vehicle or the viewing position of the user.

[0111] Step S120: determining that the light modulation assembly 200 is in a power-off state or a power-on state based on the viewing surface.

[0112] Referring to FIGS. 1, 2, and 12, in step S110, the running state of the vehicle can include an ignition state and an engine-off state. For example, the ignition state refers to the state of the vehicle in the case of driving, and the engine-off state refers to the state of the vehicle in the case of parking, waiting, refueling, and the like. The viewing position of the user can be inside the vehicle or outside the vehicle. The viewing surface refers to the side display surface on which the user views. For example, when the user such as a driver or a passenger views inside the vehicle, one of the first display surface 101 and the second display surface 102 that faces the inside of the vehicle can be determined as the viewing surface. For example, when the vehicle displays a display image to the outside of the vehicle, one of the first display surface 101 and the second display surface 102 that faces the outside of the vehicle can be determined as the viewing surface. For example, the vehicle can display a display image to the outside of the vehicle in the engine-off state, but the present disclosure is not limited thereto, and the vehicle can also display a display image to the inside of the vehicle according to the user's demand. For example, when the user inside the vehicle views and the user outside the vehicle views, both of the first display surface 101 and the second display surface 102 can be determined as the viewing surfaces.

[0113] Referring to FIGS. 1, 2, and 12, in step S120, according to the viewing surface, it can be determined whether the light modulation assembly 200 needs to be light modulated to change the light transmittance, and then it can be determined whether to power on the light modulation assembly 200.

[0114] Referring to FIGS. 1, 2 and 12, the control method of the dimming module provided by the embodiments of the present disclosure can determine the viewing surface according to the running state of the vehicle or the viewing position of the user, and then determine whether to power on the dimming assembly 200 based on the viewing surface. Since the light transmittance of the dimming area 210a of the first dimming piece 210 and the dimming area 220a of the second dimming piece 220 are different, the user can watch from the side with higher light transmittance without powering on, thereby achieving better viewing effect while saving energy.

[0115] Referring to FIGS. 1, 2 and 12, for example, in step S120, after determining the viewing surface, the size relationship between the light transmittance of the dimming area 210a of the first dimming piece 210 and the light transmittance of the dimming area 220a of the second dimming piece 220 can be determined. Then, based on the size relationship, the dimming assembly 200 can be determined to be in the powered-off state or the powered-on state. For example, when the first display surface 101 is the viewing surface, if the light transmittance of the dimming area 210a of the first dimming piece 210 is greater than the light transmittance of the dimming area 220a of the second dimming piece 220, the dimming assembly 200 does not need to be powered on, and better display effect can be achieved, thereby effectively reducing energy consumption. If the light transmittance of the dimming area of the first dimming piece is less than the light transmittance of the dimming area of the second dimming piece, the dimming assembly can be powered on, and the light transmittance of at least one of the dimming area of the first dimming piece and the dimming area of the second dimming piece can be adjusted to achieve the display effect required by the user. However, the present disclosure is not limited thereto, and the dimming assembly can also be determined to be in the powered-off state or the powered-on state according to other user requirements.

[0116] Referring to FIGS. 1 and 2, in some examples, in the powered-off state of the dimming assembly 200, the light transmittance of the dimming area 210a of the first dimming piece 210 is less than the light transmittance of the dimming area 220a of the second dimming piece 220. For example, in the powered-off state of the dimming assembly 200, the first dimming piece 210 is in the dark state, and the second dimming piece 220 is in the bright state.

[0117] Referring to FIGS. 1 and 2, in response to the first display surface 101 being the viewing surface, the dimming assembly 200 is in the powered-on state, so that the light transmittance of the dimming area 210a of the first dimming piece 210 is greater than the light transmittance of the dimming area 220a of the second dimming piece 220. When the dimming assembly 200 is in the powered-off state, the light transmittance of the dimming area 210a of the first dimming piece 210 is low. When the user watches from the side of the first display surface 101, the dimming assembly 200 can be powered on to increase the light transmittance of the dimming area 210a of the first dimming piece 210, and at the same time, the light transmittance of the dimming area 220a of the second dimming piece 220 can be reduced, so that the light transmittance of the dimming area 210a of the first dimming piece 210 is greater than the light transmittance of the dimming area 220a of the second dimming piece 220, thereby facilitating the user to watch the first display surface 101.

[0118] Referring to FIGS. 1 and 2, the light modulation assembly 200 is in a power-off state in response to the second display surface 102 being a viewing surface. Since the light modulation assembly 200 is in the power-off state, the light transmittance of the light modulation region 220a of the second light modulation member 220 is greater than the light transmittance of the light modulation region 210a of the first light modulation member 210, thereby effectively reducing energy consumption without energizing the light modulation assembly 200.

[0119] Referring to FIGS. 1 and 2, for example, the first light modulation member 210 in the power-off dark state is disposed inside the vehicle and tends to display outwardly. When the light modulation module displays outwardly, the light modulation assembly 200 can be powered off and the display screen 100 can display after the vehicle is turned off. After the vehicle is turned on, at least one of the light transmittance of the light modulation region 210a of the first light modulation member 210 and the light transmittance of the light modulation region 220a of the second light modulation member 220 can be changed by energizing the light modulation assembly 200 as needed. For example, at least one of the first light modulation member 210 and the second light modulation member 220 can also be in a power-on state after the vehicle is turned on and the light modulation module displays outwardly. For example, at least one of the first light modulation member 210 and the second light modulation member 220 can also be powered off without interfering with the driver's line of sight, which is not limited in the present disclosure.

[0120] Referring to FIGS. 1 and 2, for example, the first light modulation member 210 in the power-off dark state is disposed inside the vehicle and tends to display inwardly, the light modulation assembly 200 can be energized to increase the light transmittance of the light modulation region 210a of the first light modulation member 210 and decrease the light transmittance of the light modulation region 220a of the second light modulation member 220. For example, the first light modulation member 210 can be energized to increase the light transmittance of the light modulation region 210a of the first light modulation member 210 and the second light modulation member 220 can be powered off, which can also achieve transparent display of the display screen 100. In addition, the second light modulation member 220 can also be energized to reduce the light transmittance of the light modulation region 220a of the second light modulation member 220 to improve the display effect of the display screen 100. For example, the light transmittance of the light modulation region 220a of the second light modulation member 220 can be increased to a certain value or more to prevent affecting the viewing experience of the user inside the vehicle.

[0121] Referring to FIGS. 1 and 2, for example, when both the first light modulation member 210 and the second light modulation member 220 are powered off, the light transmittance of the light modulation assembly 200 depends on the light transmittance of the first light modulation member 210 in the power-off dark state. When the first light modulation member 210 is powered off and the second light modulation member 220 is energized, the light transmittance of the light modulation assembly 200 can reach a minimum value. When the first light modulation member 210 is energized and the second light modulation member 220 is powered off, the light transmittance of the light modulation assembly 200 can reach a maximum value. When the first light modulation member 210 and the second light modulation member 220 are simultaneously energized, the light transmittance of the light modulation assembly 200 depends on the light transmittance of the first light modulation member 210 and the light transmittance of the second light modulation member 220.

[0122] Referring to FIGS. 1 and 2, for example, the first light adjustment piece 210 in a dark state is powered off and is disposed on the outside of the vehicle and tends to display inwardly. The light adjustment assembly 200 can be in a powered-off state, and the display screen 100 displays inwardly. After the vehicle is started (for example, the vehicle is in a running state), and the light adjustment assembly is used for outward display, the first light adjustment piece 210 and the second light adjustment piece 220 can be powered on, the light transmittance of the second light adjustment piece 220 is increased, and the light transmittance of the first light adjustment piece 210 is reduced. For example, the first light adjustment piece 210 or the second light adjustment piece 220 can also be powered on alone to achieve outward display.

[0123] Referring to FIGS. 1 and 2, in some examples, the method further comprises: in response to that adjusting the light transmittance of the light adjustment area 210a of the first light adjustment piece 210 alone can reach the preset light transmittance of the light adjustment assembly 200, adjusting the light transmittance of the light adjustment area 210a of the first light adjustment piece 210 to reach the preset light transmittance; or, in response to that adjusting the light transmittance of the light adjustment area 220a of the second light adjustment piece 220 alone can reach the preset light transmittance, adjusting the light transmittance of the light adjustment area 220a of the second light adjustment piece 220 to reach the preset light transmittance. The preset light transmittance can be set according to user needs. For example, when it is needed to make the occupant or the driver in the vehicle see the scene outside the vehicle more clearly, the light transmittance of the light adjustment assembly 200 can be increased according to user needs to reach the preset light transmittance with a larger light transmittance. For example, when it is needed to make the light adjustment assembly 200 reach a lower light transmittance to improve the privacy in the vehicle, the light transmittance of the light adjustment assembly 200 can be reduced to reach the preset light transmittance with a smaller light transmittance required by the user.

[0124] Referring to FIGS. 1 and 2, for example, when adjusting the light transmittance of the light adjustment area 210a of the first light adjustment piece 210 alone can make the light adjustment assembly 200 reach the preset light transmittance, the first light adjustment piece 210 can be adjusted alone. For example, when adjusting the light transmittance of the light adjustment area 220a of the second light adjustment piece 220 alone can make the light adjustment assembly 200 reach the preset light transmittance, the second light adjustment piece 220 can be adjusted alone.

[0125] Referring to FIGS. 1 and 2, the method further includes adjusting the transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 and the transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 to reach the preset transmittance of the light-adjusting assembly 200, in response to neither adjusting the transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 nor adjusting the transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 being able to reach the preset transmittance of the light-adjusting assembly 200. For example, when the light-adjusting assembly 200 cannot reach the preset transmittance by adjusting only the first light-adjusting piece 210 or the second light-adjusting piece 220, the first light-adjusting piece 210 and the second light-adjusting piece 220 can be adjusted simultaneously. For example, the transmittance of the light-adjusting area of one of the first light-adjusting piece 210 and the second light-adjusting piece 220 can be increased, and the transmittance of the light-adjusting area of the other of the first light-adjusting piece 210 and the second light-adjusting piece 220 can be decreased.

[0126] Referring to FIGS. 1 and 2, in some examples, in response to adjusting the transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 being able to reach the preset transmittance of the light-adjusting assembly 200 and adjusting the transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 being able to reach the preset transmittance, a first power consumption of adjusting the transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 to reach the preset transmittance is obtained, and a second power consumption of adjusting the transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 to reach the preset transmittance is obtained. For example, when adjusting the first light-adjusting piece 210 and adjusting the second light-adjusting piece 220 can both reach the preset transmittance, the adjustment mode with lower power consumption can be selected for adjustment. For example, the display screen 100 can display a fog image to improve the light-shielding effect of the light-adjusting assembly.

[0127] Referring to FIGS. 1 and 2, for example, in response to the first power consumption being less than the second power consumption, it is determined to adjust the transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 to reach the preset transmittance. When the power consumption of adjusting the transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 is lower, the first light-adjusting piece 210 is selected for adjustment.

[0128] Referring to FIGS. 1 and 2, for example, in response to the second power consumption being less than the first power consumption, it is determined to adjust the transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 to reach the preset transmittance. When the power consumption of adjusting the transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 is lower, the first light-adjusting piece 210 is selected for adjustment.

[0129] Referring to FIGS. 1 and 2, for example, in response to the first power consumption being equal to the second power consumption, it is determined to adjust any one of the transmittance of the light-adjusting area 210a of the first light-adjusting piece 210 and the transmittance of the light-adjusting area 220a of the second light-adjusting piece 220 to reach the preset transmittance. When the power consumption of adjusting the first light-adjusting piece 210 and the power consumption of adjusting the second light-adjusting piece 220 are the same, any one of the light-adjusting pieces can be selected for light adjustment.

[0130] Referring to FIGS. 1 and 2, in some examples, the method further includes increasing the light transmittance of the light modulation assembly 200 in response to the display screen 100 being in a non-working state. For example, the non-working state is that the display screen 100 does not display a picture. For example, the non-working state is that the display screen 100 is in a state of being powered off. For example, when the display screen 100 does not display information, the light modulation assembly can be a common glass, and increasing the light transmittance of the light modulation assembly 200 can enable the user inside the vehicle to see the scene outside the vehicle more clearly, or facilitate the user outside the vehicle to see the scene inside the vehicle more clearly.

[0131] Referring to FIGS. 1 and 2, in some examples, the light transmittance of the light modulation region 210a of the first light modulation piece 210 is less than the light transmittance of the light modulation region 220a of the second light modulation piece 220 in a power-off state. For example, in the power-off state, the first light modulation piece 210 is in a dark state, and the second light modulation piece 220 is in a bright state. Increasing the light transmittance of the light modulation assembly 200 includes increasing the light transmittance of the light modulation region 210a of the first light modulation piece 210 under the action of an electric field, and powering off the second light modulation piece 220 to reach the maximum light transmittance of the light modulation region 220a of the second light modulation piece 220. For example, the first light modulation piece 210 can be powered on, and after the electric field intensity reaches a preset intensity, the light transmittance of the light modulation region 210a of the first light modulation piece 210 increases with the increase of the electric field intensity. At the same time, the light transmittance of the second light modulation piece 220 reaches a maximum value when powered off, so that the second light modulation piece 220 can be kept powered off, or the second light modulation piece 220 is switched from a powered-on state to a power-off state.

[0132] Referring to FIG. 4, in some examples, the first display surface 101 includes a first display region 101a, and the second display surface 102 includes a second display region 102a. For example, the first display region 101a and the second display region 102a can display different pictures. On the first display surface 101, the orthographic projections of the first display region 101a and the second display region 102a do not overlap, so that the pictures displayed in the first display region 101a and the second display region 102a do not interfere with each other.

[0133] Referring to FIG. 4, the light-adjusting area 210a of the first light-adjusting piece 210 includes a first light-adjusting area Z1 and a second light-adjusting area Z2, and the light-adjusting area 220a of the second light-adjusting piece 220 includes a third light-adjusting area Z3 and a fourth light-adjusting area Z4; the orthographic projection of the first light-adjusting area Z1 on the first display surface 101 and the orthographic projection of the third light-adjusting area Z3 on the first display surface 101 both overlap the first display area 101a; the orthographic projection of the second light-adjusting area Z2 on the second display surface 102 and the orthographic projection of the fourth light-adjusting area Z4 on the second display surface 102 both overlap the second display area 102a. For example, the orthographic projection of the first light-adjusting area Z1 on the first display surface 101 and the orthographic projection of the third light-adjusting area Z3 on the first display surface 101 both partially overlap or completely overlap the first display area 101a. For example, the orthographic projection of the second light-adjusting area Z2 on the second display surface 102 and the orthographic projection of the fourth light-adjusting area Z4 on the second display surface 102 both partially overlap or completely overlap the second display area 102a.

[0134] Referring to FIG. 4, for example, the first light-adjusting area Z1 can be the same area as the first area A1 in the foregoing embodiment, the second light-adjusting area Z2 can be the same area as the second area A2 in the foregoing embodiment, the third light-adjusting area Z3 can be the same area as the third area A3 in the foregoing embodiment, and the fourth light-adjusting area Z4 can be the same area as the fourth area A4 in the foregoing embodiment.

[0135] Referring to FIG. 4, the method further includes: in response to viewing the first display area 101a, making the light transmittance of the first light-adjusting area Z1 greater than the light transmittance of the third light-adjusting area Z3. For example, if the light transmittance of the first light-adjusting area Z1 in the power-off state is greater than the light transmittance of the third light-adjusting area Z3, the light-adjusting assembly 200 does not need to be powered on. In response to viewing the second display area 102a, making the light transmittance of the second light-adjusting area Z2 less than the light transmittance of the fourth light-adjusting area Z4. For example, if the light transmittance of the fourth light-adjusting area Z4 in the power-off state is greater than the light transmittance of the second light-adjusting area Z2, the light-adjusting assembly 200 does not need to be powered on. In this way, the simultaneous viewing of the user inside and outside the vehicle can be achieved.

[0136] Referring to FIG. 4, for example, in the power-off state, the first light-adjusting area Z1 is in the bright state and reaches the maximum light transmittance, the second light-adjusting area Z2 is in the dark state and reaches the minimum light transmittance, the third light-adjusting area Z3 is in the dark state and reaches the minimum light transmittance, and the fourth light-adjusting area Z4 is in the bright state and reaches the maximum light transmittance. At this time, the user can obtain a better viewing effect through the first light-adjusting area Z1 and the fourth light-adjusting area Z4, respectively, in the power-off state of saving energy, for example, the user inside the vehicle and the user outside the vehicle can view through different areas, respectively. It can be understood that if the user needs to view through the second light-adjusting area Z2 and the third light-adjusting area Z3, the light-adjusting assembly 200 can be in the power-on state to change the light transmittance of each light-adjusting area to meet the user's needs.

[0137] For example, the first light-adjusting area can reduce the light transmittance in the power-on state (e.g., the voltage is positive), and the second light-adjusting area can reach the minimum light transmittance in the power-off state (e.g., the voltage is zero). For example, the third light-adjusting area can reach the minimum light transmittance in the power-off state (e.g., the voltage is zero), and the fourth light-adjusting area can reduce the light transmittance in the power-on state (e.g., the voltage is positive). It can be understood that the second light-adjusting area and the third light-adjusting area can also increase the light transmittance in the power-on state (e.g., the voltage is positive), which is not described herein again.

[0138] For example, the light-adjusting assembly can also make the first light-adjusting area, the second light-adjusting area, the third light-adjusting area and the fourth light-adjusting area all in the dark state and reach the minimum light transmittance in the power-off state. Only the first light-adjusting area and the fourth light-adjusting area can be powered on to increase the light transmittance of the first light-adjusting area and the fourth light-adjusting area, so that the viewing on both sides of the light-adjusting module can be realized. For example, the light-adjusting assembly can also make the first light-adjusting area, the second light-adjusting area, the third light-adjusting area and the fourth light-adjusting area all in the bright state and reach the maximum light transmittance in the power-off state. Only the first light-adjusting area and the fourth light-adjusting area can be powered on to reduce the light transmittance of the first light-adjusting area and the fourth light-adjusting area, so that the viewing on both sides of the light-adjusting module can also be realized.

[0139] Referring to FIG. 4, when the display screen 100 does not display, the light-adjusting module can also be used as ordinary glass, and the light transmittance of each light-adjusting area can be changed according to the user's demand. For example, the light-adjusting area in the dark state in the power-off state is powered on to increase the light transmittance of the corresponding light-adjusting area, and the light-adjusting area in the bright state is kept powered off, so that the light transmittance of the light-adjusting assembly 200 is increased to more clearly observe the situation inside and outside the vehicle. For example, the light-adjusting area in the bright state in the power-off state is powered on to reduce the light transmittance of the corresponding light-adjusting area, and the light-adjusting area in the dark state is kept powered off, so that the light transmittance of the light-adjusting assembly 200 is reduced to improve the privacy in the vehicle.

[0140] Referring to FIG. 6, in some examples, the method further includes: in response to the display screen 100 being in the non-working state, powering off the light-adjusting assembly 200 to reach the maximum light transmittance of the first light-adjusting area Z1, the minimum light transmittance of the second light-adjusting area Z2, the maximum light transmittance of the third light-adjusting area Z3, and the minimum light transmittance of the fourth light-adjusting area Z4. For example, when the display screen 100 does not display information, the first light-adjusting area Z1 and the third light-adjusting area Z3 opposite to each other can be in the bright state when powered off, and the second light-adjusting area Z2 and the fourth light-adjusting area Z4 opposite to each other can be in the dark state when powered off. Thus, when the display screen 100 is in the non-working state, the light-adjusting module can be used as ordinary glass, so that the user can view the scene inside and outside the vehicle from the first light-adjusting area Z1 and the third light-adjusting area Z3, and improve the privacy in the vehicle through the second light-adjusting area Z2 and the fourth light-adjusting area Z4.
