[0001] The present application relates to the technical field of vehicle display devices, and more particularly, to a vehicle-mounted rearview mirror and a vehicle. BACKGROUND

[0002] At present, the rearview mirror in a vehicle usually has multiple working modes, such as a lens mode and a display mode. In the lens mode, the rearview mirror can perform mirror reflection, and in the display mode, the rearview mirror can realize a reversing image function.

[0003] However, the rearview mirror in the related art can only work in the lens mode or the display mode alone, resulting in monotonous display effect of the rearview mirror, and the user needs to frequently switch between the two modes, resulting in poor display timeliness of the rearview mirror. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a vehicle-mounted rearview mirror and a vehicle, aiming at solving the problem of monotonous display effect and poor display timeliness of the rearview mirror.

[0005] In a first aspect, a vehicle-mounted rearview mirror is provided, which includes a first light control area and a second light control area. The first light control area and the second light control area can independently display image information of the same or different sources, and the image information at least includes first image information of a vehicle exterior and second image information of a vehicle interior.

[0006] In the above technical solution, the vehicle-mounted rearview mirror provided by the present application has a relatively rich display effect. Assuming that one of the display sources is in the vehicle, the second image information provided by the display source is a picture of the vehicle interior, and the other display source is outside the vehicle, the first image information provided by the display source is a vehicle condition picture of the vehicle exterior. The first light control area and the second light control area can simultaneously display image information provided by the same display source, such as simultaneously displaying the picture of the vehicle interior or the vehicle condition picture of the vehicle exterior. The first light control area and the second light control area can also simultaneously display image information provided by different display sources, that is, simultaneously displaying the picture of the vehicle interior and the vehicle condition picture of the vehicle exterior. At this time, different image information can be simultaneously displayed by one vehicle-mounted rearview mirror, and the display state of the vehicle-mounted rearview mirror does not need to be switched. The user can observe the information inside and outside the vehicle through one vehicle-mounted rearview mirror, the display timeliness is high, and the phenomenon of safety hazard caused by poor display timeliness is improved.

[0007] In combination with the first aspect, in some possible implementation manners, the vehicle-mounted rearview mirror includes a display module, a reflective layer, and a light control module. The display module is configured to generate the first image information. The reflective layer is located on the light exit side of the display module, and the reflective layer is configured to generate the second image information. The first light control area and the second light control area are formed in the light control module, and the transmittance of the first light control area and the second light control area is adjustable.

[0008] In the technical solution, the first light control area and the second light control area in the vehicle-mounted rearview mirror can independently display the first image information with the same source, or the second image information with the same source, or the first image information and the second image information with different sources, that is, one displays the first image information and the other displays the second image information, and the display effect is relatively rich. By adjusting the transmittance of the first light control area and the second light control area, the display state of the vehicle-mounted rearview mirror can be switched, and the adjustment flexibility is relatively high. In addition, the vehicle-mounted rearview mirror can simultaneously display the first image information and the second image information, that is, the vehicle-mounted rearview mirror can simultaneously display the picture inside the vehicle and the vehicle condition picture outside the vehicle. At this time, the display state of the vehicle-mounted rearview mirror does not need to be switched, and the user can observe the information inside and outside the vehicle through one vehicle-mounted rearview mirror, the display timeliness is relatively high, and the phenomenon that the display timeliness is relatively poor and causes certain safety hazards is improved.

[0009] In combination with the first aspect and the above implementation manners, in some possible implementation manners, the transmittance of the first light control area and the second light control area is different, so that the first light control area and the second light control area can independently display the first image information and the second image information with different sources.

[0010] In the technical solution, the first controller adjusts the transmittance of the first light control area and the second light control area to different transmittances, so that the vehicle-mounted rearview mirror can simultaneously present the first image information and the second image information, and the adjustment flexibility and the adjustment reliability are relatively high. In addition, the first controller can correspondingly adjust the transmittance of the first light control area and the second light control area according to different display pictures, so as to independently adjust the brightness and the contrast of the first light control area and the second light control area, thereby improving the display and reflection quality of the vehicle-mounted rearview mirror.

[0011] In combination with the first aspect and the above implementation manners, in some possible implementation manners, the transmittance of the first light control area is 5% to 10%, and the transmittance of the second light control area is 80% to 90%; or, the transmittance of the first light control area is 80% to 90%, and the transmittance of the second light control area is 5% to 10%.

[0012] In combination with the first aspect and the above implementation manners, in some possible implementation manners, the transmittance of the first light control area and the second light control area is the same; the display module includes a display panel and a second controller which are stacked; the second controller is electrically connected with the display panel, and the second controller is used to adjust the brightness of the display panel.

[0013] With reference to the first aspect, in some possible implementation manners, the light control module comprises a first cover plate, a light control layer, a second cover plate and a first controller which are arranged in a stack; the first light control area and the second light control area are formed in the light control layer, the first controller is electrically connected with the first light control area and the second light control area, and the first controller is configured to adjust the transmittance of the first light control area and the second light control area.

[0014] In the technical solution, the transmittance of the first light control area and the second light control area can be adjusted simultaneously by using one first controller, so that the display state of the vehicle rearview mirror can be switched, and the switching reliability and flexibility are high. In addition, the light control layer is located between the first cover plate and the second cover plate, that is, the first cover plate and the second cover plate provide a physical barrier for the light control layer, so as to prevent dust, moisture and pollutants from the outside from entering the light control layer and affecting the light control effect of the light control layer. In addition, the first cover plate and the second cover plate can effectively prevent the surface of the light control layer from being scratched or other mechanical damage, so as to improve the light control accuracy and reliability of the light control layer.

[0015] With reference to the first aspect and the implementation manners, in some possible implementation manners, the transmittance of the first light control area and the second light control area is 8% to 10%; or, the transmittance of the first light control area and the second light control area is 30% to 40%.

[0016] With reference to the first aspect and the implementation manners, in some possible implementation manners, the vehicle rearview mirror further comprises a glass cover plate, the reflective layer is located between the glass cover plate and the display module, and when the light control module is arranged on the side of the reflective layer away from the display module, the light control module and the glass cover plate are connected by using a bonding technology.

[0017] In the technical solution, the air layer between the glass cover plate and the light control module is completely filled, so that the glass cover plate and the light control module are tightly combined. In this way, the air layer between the glass cover plate and the light control module is eliminated, the reflection and refraction of light are reduced, and the light transmittance and display effect are improved.

DETAILED DESCRIPTION

[0030] The technical solutions in the present application will be described clearly and completely below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0031] Hereinafter, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features.

[0032] Vehicles are usually equipped with vehicle-mounted rearview mirrors to observe the road conditions behind the vehicle. With the development of technology, the vehicle-mounted rearview mirrors currently usually have multiple working modes, such as a lens mode and a display mode. In the lens mode, the vehicle-mounted rearview mirror can perform mirror reflection, that is, the vehicle-mounted rearview mirror can reflect the road conditions behind the vehicle through the light reflection characteristics thereof, and in order to reduce the interference of strong light from the rear vehicle when the vehicle is driving at night, the vehicle-mounted rearview mirror usually also has an anti-dazzling mirror (such as a manual anti-dazzling mirror or an automatic anti-dazzling mirror) to improve driving safety. In the display mode, the rearview mirror can realize a reversing image function, that is, a camera connected with the vehicle-mounted rearview mirror is arranged at the tail of the vehicle, the camera can collect the road conditions behind the vehicle, and the vehicle-mounted rearview mirror can display images based on the road conditions collected by the camera to realize the reversing image function.

[0033] However, the rearview mirror in the related art can only work in the lens mode or the display mode alone, resulting in a relatively monotonous display effect of the rearview mirror. At present, an automatic anti-dazzling mirror is usually superimposed on the display of the rearview mirror, and manual switching between the display mode and the lens mode is realized through corresponding buttons. In this state, the user needs to frequently switch between the two modes, resulting in poor display and timeliness of the rearview mirror and a certain safety hazard. Secondly, the camera is arranged at the tail of the vehicle and cannot collect the field of view of the second row and the third row inside the vehicle, making it difficult to observe the passengers in the second row and the third row.

[0034] Therefore, the embodiments of the present application provide a vehicle-mounted rearview mirror and a vehicle, the display effect of the vehicle-mounted rearview mirror is relatively rich, and the display state of the vehicle-mounted rearview mirror can be switched by switching the image information displayed by the first light control area and the second light control area, so that the adjustment flexibility and the display timeliness are high.

[0035] The vehicle-mounted rearview mirror and the vehicle provided by the embodiments of the present application will be described below with reference to the accompanying drawings.

[0036] The embodiments of the present application provide a vehicle, as shown in the figure, Figure 1 The vehicle includes a vehicle-mounted rearview mirror 1 and a camera 2. The vehicle-mounted rearview mirror 1 is arranged inside the vehicle body, and the camera 2 is arranged outside the vehicle body, specifically at the tail of the vehicle body. The camera 2 is electrically connected with the vehicle-mounted rearview mirror 1. The camera 2 is used to collect the road conditions behind the vehicle, and the vehicle-mounted rearview mirror 1 can generate corresponding display images based on the road conditions collected by the camera 2, such as generating a reversing image.

[0037] In order to enable the vehicle-mounted rearview mirror 1 provided by the present application to perform multi-mode display, in one example, as shown in the figure, Figure 2As shown, the vehicle-mounted rearview mirror 1 provided in the present application can include a first light control area 1A and a second light control area 1B, and the first light control area 1A and the second light control area 1B can independently display image information of the same or different sources, and the image information at least includes first image information showing the outside of the vehicle and second image information showing the inside of the vehicle.

[0038] In this example, the display effect of the vehicle-mounted rearview mirror is relatively rich. Assuming that one of the display sources is in the vehicle, and the second image information provided by the display source is the picture of the inside of the vehicle, and the other display source is outside the vehicle, and the first image information provided by the display source is the vehicle condition picture outside the vehicle. The first light control area 1A and the second light control area 1B can simultaneously display image information provided by the same display source, for example, simultaneously display the picture of the inside of the vehicle, or simultaneously display the vehicle condition picture outside the vehicle. The first light control area 1A and the second light control area 1B can also simultaneously display image information provided by different display sources, that is, simultaneously display the picture of the inside of the vehicle and the vehicle condition picture outside the vehicle. At this time, different image information can be simultaneously displayed through one vehicle-mounted rearview mirror 1. At this time, it is not necessary to switch the display state of the vehicle-mounted rearview mirror 1, and the user can simultaneously observe the information inside and outside the vehicle through one vehicle-mounted rearview mirror 1. The display timeliness is high, and the phenomenon of safety hidden danger caused by poor display timeliness is improved.

[0039] In one example, please refer to Figure 3 and Figure 4 As shown, the vehicle-mounted rearview mirror 1 provided in the present application can include a display module 11, a reflective layer 12, a light control module 13, and a glass cover plate 14. The display module 11 is connected with the camera 2, the reflective layer 12 is located on the light-emitting side of the display module 11, and the reflective layer 12 is located between the glass cover plate 14 and the display module 11. As shown in Figure 3 , the light control module 13 can be arranged on the side of the reflective layer 12 close to the display module 11, or as shown in Figure 4 , the light control module 13 can be arranged on the other side of the reflective layer 12 away from the display module 11, and at this time, the light control module 13 is located between the reflective layer 12 and the cover glass 14.

[0040] Optionally, the light control module 13 is connected to one side of the reflective layer 12 or the other side of the reflective layer 12 by lamination technology, and can also be connected by electroplating lamination. When the light control module 13 is arranged on the other side of the reflective layer 12 away from the display module 11, the light control module 13 is connected to the glass cover plate 14 by lamination technology, for example, optical clear adhesive (OCA) or liquid optical clear adhesive (LOCA) is used to completely fill the air layer between the glass cover plate 14 and the light control module 13, so that the two are tightly combined. In this way, the air layer between the glass cover plate 14 and the light control module 13 is eliminated, the reflection and refraction of light are reduced, and the light transmittance and display effect are improved. The light control module 13 and the reflective layer 12, the glass cover plate 14 and the light control module 13 can also be connected in other ways, and the present application does not make specific limitations.

[0041] In this example, the display module 11 is used to generate first image information. Specifically, the camera 2 can collect road condition information behind the vehicle, and the display module 11 can generate first image information based on the road condition information provided by the camera 2. The first image information can refer to the image information of the reversing image. The reflective layer 12 is used to generate second image information. The second image information refers to image information of a display inside the vehicle, that is, image information formed by the mirror reflection characteristic of the reflective layer 12.

[0042] Among them, as Figure 5As shown, the first light control area 1A and the second light control area 1B are formed in the light control module 13, and the transmittance of the first light control area 1A and the second light control area 1B is adjustable, so that the first light control area 1A and the second light control area 1B can independently display the first image information or the second image information of the same source, or display the first image information and the second image information of different sources. By switching the image information displayed by the first light control area 1A and the second light control area 1B, the display state of the vehicle rearview mirror 1 can be switched. The display state includes a first state of displaying the first image information, a second state of displaying the second image information, and a third state of displaying part of the first image information and part of the second image information. At this time, when the display state of the vehicle rearview mirror 1 is the first state, the vehicle rearview mirror 1 needs to display the first image information, that is, the display module 11 needs to perform picture display. In order to enable the first image information generated by the display module 11 to be displayed through the light control module 13, the transmittance of the first light control area 1A and the second light control area 1B can be adjusted to be high transmittance, so that the first image information generated by the display module 11 can be normally displayed through the light control module 13. When the display state of the vehicle rearview mirror 1 is the second state, the vehicle rearview mirror 1 needs to display the second image information, that is, the reflective layer 12 needs to perform mirror reflection. At this time, the transmittance of the first light control area 1A and the second light control area 1B can be adjusted to be low transmittance or even black state, so as to avoid the problem of light leakage of the lower display module 11, so that the reflective layer 12 can perform mirror reflection to make the vehicle rearview mirror 1 display the second image information. When the display state of the vehicle rearview mirror 1 is the third state, the vehicle rearview mirror 1 needs to display part of the first image information and part of the second image information. Correspondingly, one of the transmittances of the first light control area 1A and the second light control area 1B can be adjusted to be low transmittance, so that the corresponding reflective layer 12 can perform mirror reflection; the other of the transmittances of the first light control area 1A and the second light control area 1B can be adjusted to be high transmittance, so that the corresponding display module 13 can perform picture display.

[0043] Thus, the vehicle-mounted rearview mirror 1 provided by the application has a first state capable of displaying first image information, a second state capable of displaying second image information, and a third state capable of displaying part of the first image information and part of the second image information. The display effect is relatively rich, and the display state of the vehicle-mounted rearview mirror 1 can be switched by adjusting the transmittance of the first light control area 1A and the second light control area 1B, and the adjustment flexibility is relatively high. In addition, the vehicle-mounted rearview mirror 1 can also simultaneously display the first image information and the second image information, that is, the vehicle-mounted rearview mirror 1 can simultaneously display the picture inside the vehicle and the vehicle condition picture outside the vehicle at this time, and the display state of the vehicle-mounted rearview mirror 1 does not need to be switched at this time, and the user can observe the information inside and outside the vehicle through one vehicle-mounted rearview mirror 1, the display timeliness is relatively high, and the phenomenon that the display timeliness is relatively poor leads to a certain safety hazard is improved.

[0044] In one example, as shown in Figure 6 The light control module 13 provided by the application includes a first cover plate 131, a light control layer 132, a second cover plate 133 and a first controller 134 which are stacked. The first light control area 1A and the second light control area 1B are formed in the light control layer 132, the first controller 134 is electrically connected with the first light control area 1A and the second light control area 1B, and the first controller 134 is used for adjusting the transmittance of the first light control area 1A and the second light control area 1B.

[0045] In this example, when the display state of the vehicle-mounted rearview mirror 1 is the first state, the vehicle-mounted rearview mirror 1 needs to display the first image information at this time, that is, the display module 11 needs to display the picture. In order to enable the first image information generated by the display module 11 to be displayed through the light control module 13, the corresponding first controller 134 can adjust the transmittance of the first light control area 1A and the second light control area 1B to be high transmittance, so that the first image information generated by the display module 11 can be normally displayed through the light control layer 132. When the display state of the vehicle-mounted rearview mirror 1 is the second state, the vehicle-mounted rearview mirror 1 needs to display the second image information at this time, that is, the reflective layer 12 needs to perform mirror reflection. At this time, the first controller 134 can adjust the transmittance of the first light control area 1A and the second light control area 1B to be low transmittance or even black state, so as to avoid the problem of light leakage of the lower display module 11, so that the reflective layer 12 can perform mirror reflection to enable the vehicle-mounted rearview mirror 1 to display the second image information. When the display state of the vehicle-mounted rearview mirror 1 is the third state, the vehicle-mounted rearview mirror 1 needs to display part of the first image information and part of the second image information at this time. The corresponding first controller 134 can adjust one of the transmittances of the first light control area 1A and the second light control area 1B to be low transmittance, so that the corresponding reflective layer 12 can perform mirror reflection; and adjust the other of the transmittances of the first light control area 1A and the second light control area 1B to be high transmittance, so that the corresponding light control layer 132 can perform picture display.

[0046] Thus, the transmittance of the first light control area 1A and the second light control area 1B can be adjusted simultaneously by the first controller 134 to correspond to the switching of the display state of the vehicle rearview mirror 1, and the switching reliability and flexibility are high. Secondly, the light control layer 132 is located between the first cover plate 131 and the second cover plate 133, that is, the first cover plate 131 and the second cover plate 133 provide a physical barrier for the light control layer 132 to prevent dust, moisture and pollutants from the outside from entering the light control layer 132, thereby affecting the light control effect of the light control layer 132. The first cover plate 131 and the second cover plate 133 can also effectively prevent the surface of the light control layer 132 from being scratched or other mechanical damage, thereby improving the light control accuracy and reliability of the light control layer 132.

[0047] Optionally, the material of the light control layer 132 can be liquid crystal or electrochromic material. When the material of the light control layer 132 is liquid crystal, the first controller 134 can correspondingly change the deflection angle of the liquid crystal molecules in the first light control area 1A and the second light control area 1B of the light control layer 132 by adjusting the voltage applied to the light control layer 132, so as to correspondingly change the transmittance of the first light control area 1A and the second light control area 1B. That is, with the change of the voltage, the corresponding transmittance can change from small to large or from large to small. The material of the light control layer 132 can also be other materials that can achieve the above functions, and the present application does not make specific limitations.

[0048] When the vehicle rearview mirror 1 is in the first state or the second state, in order to facilitate control, the transmittance of the first light control area 1A and the second light control area 1B can be set to be the same. In one example, as shown in Figure 7 The display module 11 includes a display panel 111 and a second controller 112 stacked and arranged, the second controller 112 is electrically connected with the display panel 111, and the second controller 112 is used to adjust the brightness of the display panel 111.

[0049] In one example, when the vehicle-mounted rearview mirror 1 is in the first state, i.e., when the first light control area 1A and the second light control area 1B need to display the first image information at the same time, the second controller 112 will correspondingly adjust the brightness of the display panel 111 to high brightness, so that the display module 11 can generate corresponding first image information based on the road condition information provided by the camera 2. At the same time, the first controller 134 will control the transmittance of the first light control area 1A and the second light control area 1B to be high transmittance, so that the display module 11 can display the picture through the first light control area 1A and the second light control area 1B. When the vehicle-mounted rearview mirror 1 is in the second state, i.e., when the first light control area 1A and the second light control area 1B need to display the second image information at the same time, the second controller 112 will correspondingly adjust the brightness of the display panel 111 to low brightness, or even to non-emission, so that the display module 11 stops generating image information. At the same time, the first controller 134 will control the transmittance of the first light control area 1A and the second light control area 1B to be low transmittance, so that the reflective layer 12 performs mirror reflection.

[0050] Optionally, the display panel 111 can adopt a liquid crystal display panel (LCD), when it adopts an LCD display panel, since the LCD itself does not have the characteristic of emitting light, therefore, at this time the display panel 111 also needs to be integrated with a backlight source, and the second controller 112 will adjust the transmittance of the LCD display panel while adjusting the brightness of the backlight source, so that the display module 11 can display corresponding image information. The display panel 111 can also adopt a panel that can emit light independently, such as an organic light emitting display panel (OLED), etc., at this time it is not necessary to use a backlight source, and the display panel 111 can also select other panels that can emit light independently, and the present application does not make specific limitations.

[0051] Optionally, the low transmittance of the light control layer 132 can be set to 8% to 10%, i.e., the transmittance of the first light control area 1A and the second light control area 1B is 8% to 10%, and the high transmittance of the light control layer 132 can be 30% to 40%, i.e., the transmittance of the first light control area 1A and the second light control area 1B is 30% to 40%. It is worth noting that when the high transmittance of the light control layer 132 is 30% to 40%, in order to improve the picture display effect of the vehicle-mounted rearview mirror 1, the second controller 112 can correspondingly adjust the brightness of the display panel 111 to be bright, so that the display module 11 can normally display the picture when the light control layer 132 is in high transmittance.

[0052] In the example, when the vehicle-mounted rearview mirror 1 is in the third state, the transmittances of the first light control area 1A and the second light control area 1B can also be set to be the same, and at this time, the second controller 112 can adjust the brightness of the display panel 111 corresponding to the first light control area 1A and the second light control area 1B, so that the vehicle-mounted rearview mirror 1 can realize partition display. For example, the transmittances of the first light control area 1A and the second light control area 1B are set to 30% to 40%, and it is assumed that the first light control area 1A needs to perform mirror reflection of the corresponding reflective layer 12, and the second light control area 1B needs to perform picture display of the display module 11. The second controller 112 adjusts the brightness of the display panel 111 corresponding to the second light control area 1B. At the same time, the brightness of the display panel 111 corresponding to the first light control area 1A is dimmed, so that the reflective layer 12 corresponding to the first light control area 1A can perform mirror reflection, and the display module 11 corresponding to the second light control area 1B can perform picture display.

[0053] In order to improve the accurate adjustment of the brightness corresponding to the first light control area 1A and the second light control area 1B, optionally, the display panel 111 can be divided into a first display area and a second display area, the first display area corresponding to the first light control area 1A, and the second display area corresponding to the second light control area 1B. The first display area and the second display area are independently controlled by the second controller 112, that is, the first display area and the second display area can be independently turned on or turned off. Similarly, when the display panel 111 adopts an LCD panel, the backlight source can include a first backlight area and a second backlight area, the first backlight area corresponding to the first light control area 1A and the first display area, and the second backlight area corresponding to the second light control area 1B and the second display area. The first backlight area and the second backlight area are independently controlled by the second controller 112, that is, the first backlight area and the second backlight area can be independently turned on or turned off. In this way, while the first controller 134 adjusts the transmittances of the first light control area 1A and the second light control area 1B, the second controller 112 adjusts the backlight brightness of the first backlight area and the second backlight area and the display state of the first display area and the second display area, so that the vehicle-mounted rearview mirror 1 is in the first state, the second state or the third state.

[0054] The second controller 112 is a driver IC, and the display module 11 can also include other components, which are not limited in the present application.

[0055] In another example, when the first light control area 1A and the second light control area 1B are required to independently display first image information and second image information of different origins, the transmittances of the first light control area 1A and the second light control area 1B are different. That is, the first controller 134 adjusts the transmittances of the first light control area 1A and the second light control area 1B to different transmittances, so that the vehicle-mounted rearview mirror 1 displays the first image information in one part and the second image information in another part, that is, the first light control area 1A displays the first image information and the second light control area 1B displays the second image information, or the first light control area 1A displays the second image information and the second light control area 1B displays the first image information.

[0056] In this example, the first controller 134 can adjust the transmittance of the first light control area 1A to a low transmittance, so that the reflection layer 12 corresponding to the first light control area 1A can perform mirror reflection. At the same time, the first controller 134 adjusts the transmittance of the second light control area 1B to a high transmittance, so that the display module 13 corresponding to the second light control area 1B can perform picture display; or, the first controller 134 can adjust the transmittance of the first light control area 1A to a high transmittance, so that the display module 13 corresponding to the first light control area 1A can perform picture display. At the same time, the first controller 134 adjusts the transmittance of the second light control area 1B to a low transmittance, so that the reflection layer 12 corresponding to the second light control area 1B can perform mirror reflection.

[0057] In this way, the first controller 134 can make the vehicle-mounted rearview mirror 1 simultaneously present the first image information and the second image information by adjusting the transmittances of the first light control area 1A and the second light control area 1B to different transmittances, and the adjustment flexibility and reliability are high. Moreover, the first controller 134 can adjust the transmittances of the first light control area 1A and the second light control area 1B according to different display pictures, so as to independently adjust the brightness and contrast of the first light control area 1A and the second light control area 1B, thereby improving the display and reflection quality of the vehicle-mounted rearview mirror 1.

[0058] Optionally, the low transmittance of the light control layer 132 can be set to 5% to 10%, the high transmittance of the light control layer 132 can be 80% to 90%, in the case that the vehicle rearview mirror 1 is in the first state, the transmittance of the first light control area 1A and the second light control area 1B of the light control layer 132 is 80% to 90%, so that the display module 13 can display the picture through the first light control area 1A and the second light control area 1B. In the case that the vehicle rearview mirror 1 is in the second state, the transmittance of the first light control area 1A and the second light control area 1B of the light control layer 132 is 5% to 10%, so that the reflective layer 12 can perform mirror reflection. In the case that the vehicle rearview mirror 1 is in the third state, the transmittance of the first light control area 1A can be controlled to be 5% to 10% to make the first light control area 1A display the second image information, and the transmittance of the second light control area 1B is 80% to 90% to make the second light control area 1B display the first image information. Or the transmittance of the first light control area 1A is controlled to be 80% to 90% to make the first light control area 1A display the first image information, and the transmittance of the second light control area 1B is 5% to 10% to make the second light control area 1B display the second image information. The transmittance of the first light control area 1A and the second light control area 1B in the present application can be set according to actual needs, and the present application does not make specific limitations.

[0059] It is worth noting that the division of the first light control area 1A and the second light control area 1B can be set according to user needs. When the vehicle rearview mirror 1 is in the third state, assuming that the first light control area 1A is used for picture display and the second light control area 1B is used for mirror reflection, if the user wants to display more pictures outside the vehicle, the first light control area 1A can occupy two-thirds of the light control layer 132, and the second light control area 1B can occupy one-third of the light control layer 132. If the user wants to display evenly, the first light control area 1A can occupy one-half of the light control layer 132, and the second light control area 1B can occupy one-half of the light control layer 132. In this way, the first light control area 1A and the second light control area 1B in the light control layer 132 provided by the present application support user customization, that is, the user can select the proportion of the divided display through the setting interface, and the specific division can be set according to actual needs, and the present application does not make specific limitations.

[0060] When the vehicle-mounted rearview mirror 1 is switched from the first state to the third state, the first image information and the second image information presented in the third state can be regenerated image information. In order to improve the fluency of picture display, the first image information in the third state can also be converted from the first image information in the first state. For example, when the vehicle-mounted rearview mirror 1 is switched from the first state to the third state, the image processor in the vehicle can perform frame cropping and reduction on the first image information in the first state according to the size of the first image information in the third state, so as to retain part of the first image information in the first state, and realize the flexibility of picture switching. For another example, the field of view width of the first image information in the first state can be guaranteed unchanged, that is, the image processor can perform scaling on the first image information in the first state according to the size of the first image information in the third state, so as to realize the switching of the display state while retaining all the first image information in the first state. It should be noted that the image processor can prestore fixed scaling ratios, frame cropping sizes, reduction and enlargement sizes, etc., to realize the display of image information of different sizes in different display states of the vehicle-mounted rearview mirror 1.

[0061] In one example, as shown in FIG. 1, the vehicle provided by the present application further comprises a trigger button 3, which is electrically connected with the camera 2. When the user needs to switch the display state of the vehicle-mounted rearview mirror 1, the user can press the trigger button 3 to switch the display state of the vehicle-mounted rearview mirror 1. Figure 8

[0062] Optionally, only one trigger button 3 can be arranged in the vehicle. Assuming that the vehicle-mounted rearview mirror 1 works in the first state initially, after the user presses the trigger button 3 for the first time, the display state of the vehicle-mounted rearview mirror 1 is switched from the first state to the second state, and after the user presses the trigger button 3 again, the display state of the vehicle-mounted rearview mirror 1 is switched from the second state to the third state.

[0063] Optionally, only multiple trigger buttons 3 can be arranged in the vehicle, and each trigger button 3 corresponds to a display state. For example, assuming that there are three trigger buttons 3, the first trigger button 3 corresponds to the first state, the second trigger button 3 corresponds to the second state, and the third trigger button 3 corresponds to the third state. Assuming that the vehicle-mounted rearview mirror 1 works in the first state initially, the corresponding first trigger button 3 is pressed down. If the user wants to switch to the second state, the user can press the second trigger button 3, and if the user wants to switch to the third state, the user can press the third trigger button 3.

[0064] Optionally, the trigger button 3 can also be arranged on the central control screen of the vehicle. The user can press the trigger button 3 on the central control screen to switch the display state of the vehicle-mounted rearview mirror 1. The specific arrangement position and arrangement form of the trigger button 3 can be arranged according to actual needs, and the present application does not make specific limitations in this regard.​

[0065] In one example, the vehicle interior can be further provided with an additional camera, which is electrically connected with the vehicle-mounted rearview mirror 1, and the second image information reflected by the vehicle-mounted rearview mirror 1 is the in-vehicle picture collected by the additional camera when the vehicle-mounted rearview mirror 1 is in the second state.

[0066] In summary, the vehicle-mounted rearview mirror 1 provided by the present application can simultaneously display the image information provided by the same display source in the first light control area 1A and the second light control area 1B, for example, simultaneously display the in-vehicle picture or the vehicle condition picture outside the vehicle. The first light control area 1A and the second light control area 1B can also simultaneously display the image information provided by different display sources, that is, simultaneously display the in-vehicle picture and the vehicle condition picture outside the vehicle. At this time, different image information can be simultaneously displayed through one vehicle-mounted rearview mirror 1, and at this time, it is not necessary to switch the display state of the vehicle-mounted rearview mirror 1, and the user can simultaneously observe the in-vehicle information and the information outside the vehicle through one vehicle-mounted rearview mirror 1, the display timeliness is higher, and the phenomenon that the display timeliness is poor and there is a certain safety hazard is improved.
