Description

Display method, device, equipment, medium and program product for vehicle-mounted screen

[0001] This application claims priority to the Chinese patent application with application number 202410005578.X filed on January 2, 2024, and invention name “Display method, device, equipment, medium and program product for vehicle-mounted screen”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of in-vehicle displays, and in particular to a display method, device, equipment, medium, and program product for an in-vehicle screen. Background Art

[0003] With the development of technology, in-vehicle technology is constantly improving. While the number of in-vehicle screens is increasing, the requirements for in-vehicle screens are also getting higher and higher. For example, the requirements for anti-peeping of in-vehicle screens are also getting higher.

[0004] At present, the anti-peeping technology of car screens mainly includes: attaching an anti-peeping film to the car screen, or setting the entire car screen as an anti-peeping screen.

[0005] However, both of the above-mentioned anti-peeping technologies achieve a fixed anti-peeping effect. As the main driver moves, grows in size, or adjusts his seat, the driver can still see the content in the passenger area. The overall anti-peeping effect is poor and still has a certain degree of impact on the driver's normal driving. Summary of the Invention

[0085] To make the objectives, technical solutions, and advantages of this application more clear, the following detailed description of the embodiments of this application will be given in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0086] In this application, the terms "first", "second", etc. are used to distinguish identical or similar items with substantially the same effects and functions. It should be understood that there is no logical or temporal dependency between "first" and "second", nor is there any limitation on the quantity and execution order.

[0087] FIG1 shows a schematic diagram of a vehicle-mounted terminal 10 provided in one embodiment of the present application.

[0088] The front driving area 11 of the vehicle terminal 10 includes a main driving area, a central control area and a co-pilot area. A vehicle screen 12 is formed in these three areas, wherein each of the three areas corresponds to its own screen.

[0089] During the driving of the vehicle, the main driver or the co-driver controls the vehicle-mounted terminal 10 to generate a control instruction, and the vehicle-mounted terminal 10 displays relevant content on the vehicle-mounted screen 12 according to the control instruction.

[0090] In the embodiment of the present application, the vehicle-mounted screen 12 covers the main driving area and the co-pilot area. The vehicle-mounted screen 12 includes an instrument panel area 13 (the instrument panel area 13 is regarded as the main driving area), a central control area 14 and a co-pilot area 15. The main driver mainly views the display content in the instrument panel area 13 and the central control area 14 during driving, while the co-pilot mainly views the display content in the central control area 14 and the co-pilot area 15. The instrument panel area 13 is located in front of the main driver, the co-pilot area 15 is located in front of the co-pilot, and the central control area 14 is located between the instrument panel area 13 and the co-pilot area 15. Among them, the central control area 14 includes a co-pilot use area 140, and the co-pilot use area 140 can be freely controlled by the co-pilot.

[0091] Optionally, the main driver has a greater viewing demand for the instrument panel area 13 than the central control area 14 and / or the passenger area 15 during driving.

[0092] In an optional embodiment, the instrument panel area 13 is implemented as an independent screen area, and the central control area 14 and the passenger seat area 15 are implemented as a dual screen. Schematically, the screen display content of the central control area 14 can be linked to the passenger seat area 15. In an optional embodiment, the instrument panel area 13, the central control area 14, and the passenger seat area 15 can also be implemented as a triple screen.

[0093] In an optional embodiment, the above-mentioned triple screen can be directly implemented as a linkage control system, that is, an operation performed on any one of the triple screens can display the corresponding display content on the remaining two screens. The specific implementation form of the vehicle-mounted screen 12 will be described in detail in the following embodiments and will not be repeated here.

[0094] In this embodiment of the present application, when the passenger controls the display of content in the passenger area 140 or the passenger area 15, the vehicle terminal 10 controls the passenger area 140 or the passenger area 15 to be in anti-peeping mode or sharing mode. The passenger area 140 and the passenger area 15 serve as screens for dynamic anti-peeping adjustment, forming the target screen area 16.

[0095] In the anti-peeping mode, the target screen area 16 is not visible to the main driver, but is displayed normally to the co-driver.

[0096] In the sharing mode, the target screen area 16 can be viewed by both the primary driver and the secondary driver in terms of how the control operation is performed and the display content corresponding to the control operation.

[0097] In an optional embodiment, the passenger area 140 is closer to the main driver than the passenger area 15. In the anti-peeping mode, the anti-peeping requirement of the passenger area 140 is higher than that of the passenger area 15.

[0098] In an optional embodiment, the change of the display mode of the vehicle screen can be achieved independently by the vehicle terminal 10, or can be achieved jointly by the vehicle terminal 10 and the server.

[0099] In an optional embodiment, the vehicle terminal 10 uses a wired or wireless network to complete data exchange. The above-mentioned wireless network or wired network uses standard communication technologies and / or protocols. The network is typically the Internet, but it can also be any other network, including but not limited to any combination of a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a private network, or a virtual private network. In some embodiments, technologies and / or formats including Hypertext Markup Language (HTML) and Extensible Markup Language (XML) are used to represent data exchanged over the network. In addition, conventional encryption technologies such as Secure Sockets Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), and Internet Protocol Security (IPsec) can also be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies can also be used to replace or supplement the above-mentioned data communication technologies.

[0100] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, storage, and display, etc.), and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use, and processing of relevant data must comply with the relevant laws, regulations, and standards of the relevant countries and regions. For example, the two-dimensional cover image and two-dimensional optical disc elements involved in this application were obtained with full authorization.

[0101] In conjunction with the description of the above implementation environment, the display method of the vehicle screen involved in the embodiment of this application is explained. Figure 2 is a flowchart of the vehicle display method provided by an exemplary embodiment of this application. The method is described by applying it to a vehicle terminal with a vehicle screen. As shown in Figure 2, the method includes:

[0102] Step 200 : Control the target screen area of ​​the vehicle-mounted screen to be in one of multiple display modes.

[0103] Optionally, the in-car screen includes a central control area and a passenger area.

[0104] Optionally, the car screen also includes the main driver area.

[0105] The above-mentioned vehicle-mounted screen includes three areas, and the implementation of the vehicle-mounted screen is described in detail below.

[0106] The first implementation form: The driver's area, center console area, and passenger area of ​​the vehicle screen are implemented as three independent screen areas. That is, the vehicle screen includes three screens. When controlling the vehicle screen, the driver and / or passenger can control the three screens independently or in a coordinated manner. When controlling the three screens in a coordinated manner, the driver's area, center console area, and passenger area need to be connected, for example, the communication connection network of the three areas must be on the same network.

[0107] The second form of implementation: the main driving area and the central control area in the vehicle screen are implemented as two screens, and the co-driver area is implemented as an independent screen. That is, the vehicle screen includes two screens, and the main driving area and the central control area are divided into the two screens according to the preset screen ratio. The vehicle terminal displays the information related to the driving status in the main driving area, and displays the information unrelated to the driving status in the central control area, such as: displaying the driving speed and vehicle status information in the main driving area, and displaying the vehicle applications, etc. in the central control area. Optionally, the two screens and the co-driver area can be controlled and displayed independently, or can be controlled and displayed in linkage. When linked, the two screens and the co-driver area are connected, such as: the communication connection network of the two screens and the co-driver area is in the same network. Among them, the display ratio of the main driving area and the central control area in the two screens can be set according to actual conditions.

[0108] The third form of implementation: the main driver's area in the vehicle screen is implemented as an independent screen, and the central control area and the co-driver's area are implemented as two screens. When the vehicle terminal is in driving state, the main driver's attention is mainly focused on the driving process. The main driver gives priority to information related to the driving state of the vehicle terminal. Therefore, the main driver's area is implemented as an independent screen to prevent other display information from interfering with the main driver. During driving, the co-driver may need to use the co-driver area and the central control area, so the two areas are directly implemented as a linked screen to further improve the co-driver's operating efficiency. Optionally, the two screens and the main driver's area can be independently controlled and displayed independently, or they can be linked controlled and displayed. When linked controlled, the two screens and the main driver's area are connected, such as: the two screens and the main driver's area are in the same communication network.

[0109] The fourth implementation form: the main driver area, central control area and passenger area of ​​the vehicle screen are implemented as a triple screen. That is, the vehicle screen includes a screen, and the corresponding display content is displayed in the corresponding area of ​​the triple screen according to actual driving needs. For example, taking the main driver on the left as an example, the driving speed and detailed information of the vehicle terminal are displayed in the left area of ​​the vehicle screen (main driver area), the navigation information is displayed in the middle area of ​​the vehicle screen (central control area), and the entertainment information is displayed in the right area of ​​the vehicle screen (passenger area). The display content of the specific area can be displayed according to the actual driving status.

[0110] As shown in Figure 3, the vehicle screen 30 is illustrated as a vehicle with the driver on the left side of the vehicle terminal and the passenger on the right side. The vehicle screen 30 includes a driver's seat area 31, a central control area 32, and a passenger's seat area 33. The driver's seat area 31 is located in front of the driver, the passenger's seat area 33 is located in front of the passenger, and the central control area 32 is located between the driver's seat area 31 and the passenger's seat area 33. The passenger can control the central control area 32 and the passenger's seat area 33, while the driver can control the central control area 32.

[0111] Optionally, the center control area also includes an area for the co-pilot. The area for the co-pilot can be part of the display area in the center control area or the entire display area. As shown in Figure 4, the vehicle screen includes a main driver area 40, a center control area 41 and a co-pilot area 42. The center control area 41 includes a non-co-pilot area 410 and a co-pilot area 411. Among them, the non-co-pilot area 410 is the area in the center control area 41 other than the co-pilot area 411. During driving, in order to meet the co-pilot's greater demands for screen control, part or all of the area in the center control area 41 is set as an area that the co-pilot can operate, thereby increasing the space for the co-pilot to operate the screen area.

[0112] In the first case, the passenger area is implemented as a fixed area in the central control area.

[0113] Optionally, the central control area is divided into a passenger area according to a preset ratio. The solution of dividing the passenger area according to the preset ratio includes but is not limited to one of the following solutions.

[0114] 1. While the width of the center console remains unchanged, the passenger area is divided according to a preset length ratio. The preset length ratio is the ratio of the center console length to the passenger area length. For example, if the center console area measures 12cm*7cm and the preset length ratio is 2:1, the passenger area measures 6cm*7cm.

[0115] Second, while the center console area remains unchanged in length, the passenger area is divided according to a preset width ratio. The preset width ratio is the ratio of the center console area width to the passenger area width. For example, if the center console area is 12cm*7cm and the preset width ratio is 2:1, the passenger area will be 12cm*3.5cm.

[0116] 3. The passenger seat area is directly determined from the center console area according to a preset size ratio. The preset size ratio is the ratio of the total area of ​​the center console area to the total area of ​​the passenger seat area. For example, if the total area of ​​the center console area is 84cm2 and the preset size ratio is 2:1, the total area of ​​the passenger seat area is 42cm2.

[0117] In the above three cases, the passenger area is directly implemented as the center console area. For example, the size of the center console area is 12cm*7cm, and the preset length ratio is 1:1. The size of the passenger area is the same as the center console area, which is 12cm*7cm.

[0118] In the second case, the passenger area is implemented as a dynamically adjusted area in the central control area.

[0119] Optionally, the central control area and the co-pilot area are implemented as a linkage control system.

[0120] When the passenger area receives an expand-screen drag operation, the passenger area in the center console is determined based on the last position of the expand-screen drag operation. The expand-screen drag operation is used to instruct the user to enlarge the interface content displayed in the passenger area.

[0121] Optionally, the target screen area includes the co-pilot area and the co-pilot use area in the above content.

[0122] Schematically, when the co-pilot operates the target screen area on the vehicle screen, the display content of the target screen area also changes accordingly. The primary driver, who is driving, will inevitably see the changes in the interface in the target screen area, causing some interference to the primary driver's driving. In this embodiment of the present application, in order to further reduce the visual interference of the target screen area on the primary driver, the vehicle terminal controls the target screen area to be in one of multiple display modes.

[0123] Optionally, multiple display modes include anti-peeping mode and sharing mode.

[0124] Anti-peep mode prevents the primary driver from viewing the target screen area. In this mode, the primary driver's visibility of the displayed content in the target screen area is reduced. This prevents the secondary driver from visually reading the image information in the target screen area, allowing the primary driver to focus more on driving while maintaining visual information.

[0125] The shared mode allows the primary driver to view the target screen area. In this mode, the primary driver can see the display content of the target screen area. In other words, the primary driver can visually read the image information on the target screen area.

[0126] Optionally, in anti-peeping mode, since the passenger area in the center control area is closer to the main driver than the passenger area, in this mode, the anti-peeping requirements for the center control area are higher than those for the passenger area.

[0127] In sharing mode, the display content (visual information) in the target screen area must be read by both the main driver and the front passenger at the same time. However, in the driving state, the front passenger's control demand for the target screen is greater than that of the main driver. Therefore, in this mode, the sharing requirement of visual information in the front passenger area is higher than that in the central control area.

[0128] In an optional embodiment, when the passenger use area in the central control area is a partial area of ​​the central control area, the central control area is divided into two different areas. The screen in the central control area except the passenger use area is closer to the main driver. When the vehicle-mounted terminal is in anti-peep mode when the passenger use area in the control target screen area is in anti-peep mode, the screen in the central control area except the passenger use area is still displayed normally, and the visual information displayed therein can be read by the main driver.

[0129] Optionally, a display module is provided under the vehicle screen, and multiple display modules are provided under the central control area and the co-pilot area, and the multiple display modules are arranged in an array.

[0130] In different display modes, the working states of the first and second display modules are different. In anti-peep mode, the outgoing light on the main driver's side of the first display module is in a vertical state or deflected to the right, while the corresponding outgoing light on the second display module is in a normal outgoing state. The outgoing light on both sides of the second display module is more concentrated than the outgoing light of normal display. In sharing mode, the outgoing light on both sides of the first display module is in a normal outgoing state, while the outgoing light on the main driver's side of the second display module is deflected to the left, or the outgoing light on both sides of the second display module is more divergent than the outgoing light of normal display.

[0131] In an optional embodiment, part of the central control area is implemented as a passenger area. The first display module includes a first display submodule and a second display submodule, wherein the first display submodule is located below the passenger area, and the second display submodule is located in other screen areas of the central control area except the passenger area. When switching between anti-peeping mode and sharing mode, the second display submodule is in a normal display state. Optionally, when the main driver blocks the display content of the entire central control area, the main driver can control whether the second display submodule is in anti-peeping mode. This application does not limit this.

[0132] As shown in FIG4 , the driver's seat area 40 includes multiple display modules 400, the non-passenger seat area 410 includes multiple display modules 4100, the passenger seat area 411 includes multiple display modules 4110, and the passenger seat area 42 includes multiple display modules 420. When in anti-peep mode, the multiple display modules 400 and 4100 are in a normal display state, with the light emitted from the left side of the multiple display modules 4110 (the side closer to the driver) in a vertical state and the light emitted from the right side in a normal state. The light emitted from the multiple display modules 420 is more concentrated than the light emitted from the sides of the multiple display modules 400. When in shared mode, the multiple display modules 400 and 4100 are in a normal display state, with the light emitted from the multiple display modules 420 deflected to the left relative to the light emitted from the left side of the multiple display modules 400.

[0133] In this embodiment of the present application, a central control area and a passenger area are provided on the vehicle screen, creating a passenger area in the central control area that can be controlled by the passenger. The vehicle terminal freely controls the display mode of the target screen area, which includes both the passenger area and the passenger area. In anti-peeping mode, the target screen area effectively prevents the primary driver from viewing the content displayed, minimizing driving interference. In shared mode, the target screen area ensures that both the passenger and primary driver can view the target screen area simultaneously, achieving a dynamic anti-peeping effect.

[0134] In an optional embodiment, the switching between anti-peeping mode and sharing mode is realized only in the passenger seat area in the central control area, and the remaining screen areas in the central control area are in normal display mode. On the premise that the main driver can still view the visual information in the central control area, the passenger seat area has visual flexibility and can control whether it is in anti-peeping mode, thereby achieving the effect of dynamically adjusting the anti-peeping display and effectively improving the driving safety of the main driver.

[0135] The following describes the display method for an in-vehicle screen according to an embodiment of the present application. FIG5 is a flowchart of setting an anti-peeping mode according to an exemplary embodiment of the present application, and illustrates the method as applied to an in-vehicle terminal equipped with an in-vehicle screen. As shown in FIG5 , the process of setting the anti-peeping mode includes step 500.

[0136] Step 500: Control the target screen area to be in different anti-peeping modes.

[0137] In the embodiment of the present application, the co-pilot use area and the co-pilot area in the central control area are both screen areas for control facing the co-pilot. When the co-pilot controls at least one of the above two screen areas, the generated screen content is private to the co-pilot. For example: the co-pilot needs to complete office work in the target screen area, and the display content in the relevant screen area is private. The anti-peeping requirement of the target screen area is higher, and the visibility to the main driver needs to be lower. For another example: the co-pilot only completes office work in the co-pilot area, and the co-pilot use area is in an idle state (this idle state only means that it is not related to the operations related to the co-pilot's office work, and does not mean that the co-pilot use area is in a dormant state). At this time, when the target screen area is controlled in anti-peeping mode, the anti-peeping requirement of the co-pilot area is higher than that of the co-pilot use area.

[0138] Therefore, in the embodiment of the present application, different privacy protection levels are set for different areas of the target screen area, and different privacy protection levels have different visibility levels for the main driver. That is, different areas of the target screen area have at least two privacy protection levels.

[0139] Optionally, at least two privacy protection levels differ in at least one of the following factors: backlight intensity, screen brightness, viewing angle range, and relative light intensity.

[0140] Among them, backlight intensity is used to indicate the brightness value of the backlight light source in Liquid Crystal Display (LCD) display technology. The backlight light is emitted from the side or back of the LCD display module. Under different privacy protection levels, different areas of the target screen area correspond to different privacy protection levels, and the ability of the main driver to obtain visual information also varies accordingly. Optionally, the higher the privacy protection level, the lower the backlight intensity, and the lower the main driver's ability to obtain visual information.

[0141] Screen brightness is used to indicate the brightness value corresponding to each pixel or area in Organic Light-Emitting Diode (OLED) display technology.

[0142] The viewing angle range indicates the angle range within which the driver can observe the content displayed on the screen from the front and sides while driving. The closer the target screen area is to the driver, the more likely the displayed content is to be within the driver's viewing angle. Therefore, the closer the area is to the driver, the higher the privacy protection level.

[0143] The relative light intensity value is used to indicate the ratio of the first light intensity value to the second light intensity value of the current area, wherein the first relative light intensity value is the light intensity value that the main driver can see in anti-peeping mode, and the second light intensity value is the light intensity value that the main driver can see in sharing mode. The current area is any one or more screen areas in the target screen. Optionally, the light intensity value mentioned here is the screen brightness of the target screen area under the viewing angle of the main driver. Optionally, the lower the value of the first light intensity value, the lower the value of the relative light intensity value, and the higher the anti-peeping level corresponding to the screen area.

[0144] In an optional embodiment, the relative value of light intensity can be the light intensity value generated inside the vehicle terminal due to the influence of external light intensity, or it can be the light intensity value generated by the real-time light intensity change corresponding to the area inside the vehicle terminal, or it can be the screen display brightness value corresponding to the area. This application does not limit this.

[0145] In an optional embodiment, the vehicle terminal is provided with one or more ambient light sensors that detect ambient light intensity. Based on the ambient light intensity detected by at least one ambient light sensor, the privacy protection level of at least one area in the passenger seat area is determined, and / or the privacy protection level of at least one area in the passenger seat area is determined.

[0146] Optionally, the ambient light sensor detects external ambient light and internal ambient light, and determines the ambient light intensity of the passenger seat area and / or the area where the passenger seat area is located based on the external ambient light and the internal ambient light. The anti-peeping level of at least one area in the passenger seat area is determined, and / or the anti-peeping level of at least one area in the passenger seat area is determined. The ambient light intensity can be determined based on the difference between the external ambient light and the internal ambient light, or based on the ratio of the external ambient light to the internal ambient light, or based on the degree of influence of the external ambient light on the internal ambient light, and this application does not limit this.

[0147] Optionally, the ambient light sensor is arranged in the central control area and / or the driver's seat side window area at the front end of the vehicle terminal.

[0148] Optionally, brightness sensors are provided for all areas corresponding to the passenger seat area and all areas corresponding to the passenger seat area. All display brightness values ​​collected in each screen area are arranged in ascending order, and the anti-peeping level of at least one area of ​​the passenger seat area is determined according to the threshold range of the display brightness value, and / or the anti-peeping level of at least one area in the passenger seat area is determined.

[0149] Based on the above content, it can be seen that the target screen area includes the passenger area in the center control area and the passenger area.

[0150] During driving, the main driver has different anti-peeping requirements for different areas of the target screen area. In the embodiment of the present application, the target screen area includes different areas, and the different areas include at least two of the following areas.

[0151] Passenger area;

[0152] The left side of the passenger area;

[0153] The right side of the passenger area;

[0154] The middle area of ​​the passenger area;

[0155] The upper area of ​​the passenger area;

[0156] the lower area of ​​the passenger area;

[0157] Passenger vehicle use area;

[0158] The area to the left of the passenger seat;

[0159] The area to the right of the passenger seat;

[0160] The middle area of ​​the passenger seat;

[0161] The upper area of ​​the passenger seat;

[0162] The lower area of ​​the passenger seat.

[0163] The area position of the above area is determined based on at least one factor of the distance from the main driver, the distance from the co-driver, and the real-time ambient light intensity of the area.

[0164] The passenger area is divided into a left area of ​​the passenger area, a right area of ​​the passenger area, a middle area of ​​the passenger area, an upper area of ​​the passenger area, and a lower area of ​​the passenger area. The middle area of ​​the passenger area can be the area between the left and right areas of the passenger area, or the area between the upper and lower areas of the passenger area, which is not limited in this application.

[0165] The passenger seat area is divided into a left area of ​​the passenger seat area, a right area of ​​the passenger seat area, a middle area of ​​the passenger seat area, an upper area of ​​the passenger seat area, and a lower area of ​​the passenger seat area. The middle area of ​​the passenger seat area can be the area between the left and right areas of the passenger seat area, or the area between the upper and lower areas of the passenger seat area, which is not limited in this application.

[0166] Optionally, the above different areas may also be combined in the following forms:

[0167] The passenger area and the co-pilot area;

[0168] The passenger seat area and at least one of the areas into which the passenger seat area is divided are combined;

[0169] The upper area of ​​the passenger passenger area and at least one of the areas into which the passenger passenger area is divided are combined;

[0170] The lower area of ​​the passenger passenger area and at least one of the areas into which the passenger passenger area is divided are combined;

[0171] A middle area of ​​the passenger passenger area and at least one area of ​​the divided areas of the passenger passenger area are combined;

[0172] The left side area of ​​the passenger seat area and at least one area of ​​the divided areas of the passenger seat area are combined;

[0173] The right area of ​​the passenger seat area and at least one area of ​​the divided areas of the passenger seat area are combined;

[0174] Combining at least one of the areas where the passenger area and the passenger use area are divided;

[0175] The upper area of ​​the passenger area and at least one of the areas into which the passenger use area is divided are combined;

[0176] The lower area of ​​the passenger area and at least one of the areas into which the passenger use area is divided are combined;

[0177] The middle area of ​​the passenger area and at least one of the areas into which the passenger use area is divided are combined;

[0178] The left side area of ​​the passenger area and at least one of the areas into which the passenger area is divided are combined;

[0179] The right side area of ​​the passenger area and at least one of the areas into which the passenger use area is divided are combined.

[0180] For example, when the primary driver is on the left side of the vehicle terminal, the left side of the above-mentioned different areas is closer to the primary driver; when the primary driver is on the right side of the vehicle terminal, the left side of the above-mentioned different areas is closer to the secondary driver. For example: the farther the area is from the primary driver, the area is determined to be the secondary driver area / the right side of the secondary driver's area. The farther the area is from the secondary driver, the area is determined to be the secondary driver area / the left side of the secondary driver's area.

[0181] Alternatively, taking the case where the primary driver is on the left side of the in-vehicle terminal as an example, in normal driving, the primary driver's peripheral vision is more likely to capture perspective information from the side closer to them and above them. Therefore, changes in light intensity in the left and upper areas of the passenger seat area / passenger seat area are more likely to attract the primary driver's attention. Therefore, the area with high real-time ambient light intensity is determined to be the left area of ​​the passenger seat area / passenger seat area or the upper area of ​​the passenger seat area / passenger seat area.

[0182] Optionally, the real-time ambient light intensity can be the light intensity value generated by the external light intensity inside the vehicle terminal, or it can be the light intensity value generated by the real-time light intensity change corresponding to the area inside the vehicle terminal, or it can be the screen display brightness value corresponding to the area. This application does not limit this.

[0183] Different areas may have different privacy protection levels. Optionally, the privacy protection levels may be determined based on at least one of the distance from the primary driver, the distance from the secondary driver, and the real-time ambient light intensity of the area.

[0184] For example, the closer the area is to the primary driver, the higher the privacy protection level corresponding to that area. The closer it is to the passenger, the lower the privacy protection level corresponding to that area. The higher the real-time ambient light intensity of the area, the higher the privacy protection level corresponding to that area. Alternatively, the higher the ambient light intensity of the area where the primary driver is located, the higher the privacy protection level of the area closer to the primary driver.

[0185] In another optional embodiment, the co-pilot can control the privacy protection level of different areas in the target screen area. Each target screen area is provided with a privacy protection control. When the co-pilot controls the target screen area and needs to protect the screen content to be displayed, the privacy protection control can be triggered. When the vehicle terminal receives the trigger command corresponding to the privacy protection control, it controls the current area to be in privacy protection mode.

[0186] In the embodiments of this application, the privacy protection levels include level 1, level 2, and level 3. Level 1 privacy protection is less effective than level 2, which is less effective than level 3. In other words, level 3 provides a better privacy protection. The privacy protection effects corresponding to each privacy protection level are explained in conjunction with the following. In the following discussion, the center console area is closer to the driver, while the passenger area is farther away from the driver.

[0187] In the first case, different privacy protection levels are set based on the distance of the target screen area from the main driver. Among them, the first privacy protection level has the lowest privacy protection effect, the third privacy protection level has the highest privacy protection effect, and the second privacy protection level is between the first and third privacy protection levels.

[0212] In the third case, the privacy protection level is set according to the privacy protection effect. Among them, the first privacy protection level is used to prevent light emitted from the passenger area from entering the main driver's field of view, the second privacy protection level is used to achieve privacy protection for the passenger, and the third privacy protection level is used for the newly added area after the passenger area is adjusted.

[0213] Optionally, adjusting the passenger seat area indicates adjusting the display area of ​​the passenger seat area within the center console. For example, if the center console area has a size of 12cm*4cm and the passenger seat area has a size of 7cm*4cm before adjustment, the passenger seat area is adjusted to have a size of 9cm*4cm after adjustment.

[0214] In an embodiment of the present application, the newly added area before and after the adjustment of the passenger seat usage is used as the area where the third level of privacy protection is applied, or the adjusted passenger seat usage area is used as the area where the third level of privacy protection is applied.

[0215] Optionally, in response to receiving a page adjustment operation on the passenger area, the target screen area is controlled to be in a fourteenth sub-mode. The fourteenth sub-mode includes: the passenger area is in a level 1 privacy protection level, the newly added area after the passenger area is adjusted is in a level 3 privacy protection level, and the central control sub-area is in a level 2 privacy protection level.

[0216] In the fourth case, the anti-peeping level is set only for the passenger seat area.

[0217] Optionally, different privacy protection levels can be set for different areas of the passenger seat.

[0218] Optionally, the passenger seat area is controlled to be in the fifteenth sub-mode. The fifteenth sub-mode includes: the left side of the passenger seat area is in the third privacy protection level, the middle area of ​​the passenger seat area is in the second privacy protection level, and the right side of the passenger seat area is in the first privacy protection level. The third privacy protection level has a higher privacy protection effect than the second privacy protection level, which is higher than the first privacy protection level.

[0219] Optionally, the passenger seat area is controlled to be in a sixteenth sub-mode. The sixteenth sub-mode includes: the upper area of ​​the passenger seat area is in a third level of privacy protection, the middle area of ​​the passenger seat area is in a second level of privacy protection, and the lower area of ​​the passenger seat area is in a first level of privacy protection. The third level of privacy protection is higher than the second level, which is higher than the first level.

[0220] Optionally, the passenger seat area is controlled to be in the seventeenth sub-mode according to the display brightness values ​​of each area in the passenger seat area. The seventeenth sub-mode includes: the area in the passenger seat area whose display brightness value is within the first preset range is in the third level anti-peeping mode, the area in the passenger seat area whose display brightness value is within the second preset range is in the second level anti-peeping mode, and the area in the passenger seat area whose display brightness value is within the third preset range is in the first level anti-peeping mode. Among them, the minimum value of the first preset range is greater than the maximum value of the second preset range, and the minimum value of the second preset range is greater than the maximum value of the third preset range. The specific range setting of the display brightness value can be determined according to actual conditions, and this application does not limit this.

[0221] In the fifth case, an anti-peeping mode is set for the target screen area according to the co-pilot's use requirements for the target screen area.

[0222] Optionally, determine whether the target screen area displays projection content.

[0223] If the co-pilot projects content onto the target screen area for display and control, the content displayed on the target screen area has a certain degree of privacy and cannot be viewed by the primary driver. Therefore, the target screen area can be set to anti-peeping mode. In other words, in response to the display of projected content on the target screen area, the target screen area is controlled to be in the third-level anti-peeping mode.

[0224] If the co-pilot operates the built-in application of the vehicle system in the target screen area, it means that this part of the content does not have a certain degree of privacy and can be viewed by the main driver and the co-pilot. During the co-pilot's operation, the anti-peeping level can be adjusted according to the screen display brightness of the target screen area. That is, in response to the fact that there is no projected content displayed in the target screen area and the display brightness of the target screen area exceeds the preset brightness threshold, the screen area in the target screen area where the display brightness exceeds the preset brightness threshold is adjusted to the third-level anti-peeping mode or the second-level anti-peeping mode, and the area in the target screen area where the display brightness does not exceed the preset brightness threshold has a lower anti-peeping level than the screen area where the display brightness exceeds the preset brightness threshold.

[0225] Optionally, the privacy level of the in-vehicle applications in the target screen area is determined, and different in-vehicle applications correspond to different privacy levels. Schematically, the privacy level of social in-vehicle applications is higher than that of entertainment in-vehicle applications and higher than that of navigation in-vehicle applications.

[0226] Optionally, based on the privacy level of the in-vehicle application, the display area related to the in-vehicle application displayed in the target screen area is set to anti-peeping mode. The anti-peeping mode of the display area can apply a third-level anti-peeping level, a second-level anti-peeping level, or a first-level anti-peeping level. Different anti-peeping levels can also be set based on the privacy level of the in-vehicle application. For example, if the in-vehicle application is a social media app and the co-pilot is chatting on the social media app, the privacy level is relatively high, and the display interface corresponding to the social media app is set to a third-level anti-peeping level.

[0227] Optionally, the display interfaces of multiple in-vehicle applications can be controlled simultaneously in the target screen area, and the display interfaces corresponding to the multiple in-vehicle applications can be displayed side by side or included, which is not limited in this application.

[0228] Based on the ranking results of the privacy levels of multiple in-vehicle applications, corresponding privacy protection levels are set for different in-vehicle applications. For example, the co-pilot is operating a social networking app and a navigation app simultaneously in the target screen area. The social display interface corresponding to the social networking app is displayed as a floating window on the navigation display interface corresponding to the navigation app. The privacy level of the social networking app is higher than that of the navigation app. Different privacy protection levels are set for the social display interface and the navigation display interface, with the social display interface having a higher privacy protection level than the navigation display interface.

[0229] In the sixth case, the privacy protection level is set according to the display status of the display content in the target screen area.

[0230] Optionally, in response to dynamic content being displayed in the target screen area, the display mode of the display area displaying the dynamic content is adjusted to an anti-peeping mode. The dynamic content is used to indicate that there is an interface display change in the target screen area, and the display change can be any one of an interface switch, an interface slide, and an interface jump. Such as: playing a film or television work, sliding up and down to browse the displayed content, viewing dynamic pictures, etc. In an optional embodiment, the anti-peeping mode can also be dynamically adjusted according to the pixel transformation of the dynamic content, and the dynamic adjustment is used to adjust the anti-peeping level in the anti-peeping mode.

[0231] In response to the target screen area displaying static content, the display mode of the target screen area is set to a lower level of privacy protection mode, or to a sharing mode.

[0232] Illustratively, if the target screen area includes both dynamic display content and static display content, the display mode of the display area corresponding to the dynamic display content is set to anti-peeping mode, and the display area corresponding to the static display content is set to sharing mode.

[0233] In this embodiment of the present application, a central control area and a passenger area are provided on the vehicle screen, creating a passenger area in the central control area that can be controlled by the passenger. The vehicle terminal freely controls the display mode of the target screen area, which includes both the passenger area and the passenger area. In anti-peeping mode, the target screen area effectively prevents the primary driver from viewing the content displayed, minimizing driving interference. In shared mode, the target screen area ensures that both the passenger and primary driver can view the target screen simultaneously, achieving a dynamic anti-peeping effect.

[0234] In an optional embodiment, different anti-peeping levels are set for the vehicle screen, which not only protects the privacy of the co-driver operating the target screen area, but also ensures that the visual information of the target screen area cannot be read by the main driver, effectively improving the driving safety of the main driver.

[0235] In an optional embodiment, different anti-peeping levels are set. First, it can be directly reflected in the display brightness. While protecting the main driver from peeping, it prevents the display brightness of the target screen area from dropping too low, which will have a certain impact on the browsing experience of the co-driver; second, based on the relative value of the change in light intensity value that can occur in the main driver's peripheral vision range, the accurate value of the target screen area that cannot be seen by the main driver is reasonably determined, thereby further improving the anti-peeping effect on the main driver.

[0236] In an optional embodiment, different areas within the target screen area are determined based on the position of the main driver / co-driver and the real-time ambient light intensity of the area, providing certain support for subsequent further zoning and anti-peeping.

[0237] In an optional embodiment, different anti-peeping sub-modes are set for different areas of the target screen area. When controlling different areas, the anti-peeping mode is dynamically switched, which not only improves the comprehensiveness of the anti-peeping effect, but also improves the anti-peeping flexibility.

[0238] FIG11 is a flow chart of an in-vehicle display method provided by another exemplary embodiment of the present application, which is illustrated by applying the method to an in-vehicle terminal with an in-vehicle screen. As shown in FIG11 , the method includes:

[0239] Step 1100 , in response to a passenger area being added to the central control area, controlling the display mode of the passenger area to be consistent with the display mode of the passenger area.

[0240] Optionally, the vehicle terminal monitors the display area of ​​the central control area in real time.

[0241] When the system detects the addition of a passenger area to the center console, the display content in the center console changes. This change inevitably causes a change in visual information, which may be visible to the primary driver. In this case, the display mode for the passenger area is determined based on the display mode of the passenger area.

[0242] Optionally, the display mode of the passenger area in the current state is obtained, and the display mode of the passenger area is in a sharing mode or an anti-peeping mode.

[0243] In an embodiment of the present application, when it is detected that a passenger seat area is added to the central control area and the passenger seat area is in an anti-peeping mode, the passenger seat area is controlled to be in the anti-peeping mode.

[0244] When it is detected that a passenger area is added to the central control area and the passenger area is in the sharing mode, the passenger area is controlled to be in the sharing mode.

[0245] Optionally, the above step 1100 can also be implemented by controlling the display mode of the passenger usage area to be consistent with the display mode of the passenger area in response to receiving a control operation in the passenger usage area in the central control area.

[0246] In another optional embodiment, in response to a target area in the passenger usage area in the central control area receiving a control operation, the display mode of the target area is controlled to be consistent with the display mode of the passenger area.

[0247] The target area is at least one of the following areas:

[0248] The upper area of ​​the passenger seat;

[0249] The lower area of ​​the passenger seat;

[0250] The middle area of ​​the passenger seat;

[0251] The area to the left of the passenger seat;

[0252] The area to the right of the passenger seat.

[0253] Step 1110 , in response to no passenger area being added to the central control area, controlling the display mode of the passenger area to be opposite to the display mode of the passenger area.

[0254] During the process of monitoring the central control area by the vehicle-mounted terminal, if no new co-pilot area is detected in the central control area, it means that the original display content of the central control area will not cause certain interference to the main driver's line of sight, that is, the central control area is visible to the main driver in this case.

[0255] When no passenger area is detected to be added to the central control area, the display mode of the passenger area is controlled to be opposite to the display mode of the passenger area.

[0256] Optionally, if it is detected that there is no additional passenger area in the central control area and the passenger area is in anti-peep mode, the central control area is controlled to be in shared mode;

[0257] When it is detected that there is no additional passenger area in the central control area and the passenger area is in sharing mode, the central control area is controlled to be in anti-peep mode.

[0258] As shown in Figure 12, Figure 12 shows a schematic diagram of the working principle of the display module inside the vehicle screen in anti-peep mode. The central control area 120 includes a central control sub-area 1200 and a passenger area 1201. Multiple display modules 1210 are set under the central control sub-area 1200, multiple display modules 1220 are set under the passenger area 1201, and multiple display modules 1230 are set under the passenger area 121. In anti-peep mode, it is necessary to ensure that the light from the multiple display modules 1220 is outside the field of view 123 of the main driver 122. Optionally, the outgoing light from the left side of the multiple display modules 1220 is in a vertical state.

[0259] As shown in Figure 13, a schematic diagram illustrates the operating principle of the display modules within the vehicle screen in shared mode. The central control area 130 includes a central control sub-area 1300 and a passenger area 1301. Multiple display modules 1310 are located below the central control sub-area 1300, multiple display modules 1320 are located below the passenger area 1301, and multiple display modules 1330 are located below the passenger area 131. In anti-peep mode, it is necessary to ensure that the light from the multiple display modules 1320 is within the field of view 133 of the primary driver 132.

[0260] Fig. 14 is a flow chart of another in-vehicle display method provided based on the embodiment shown in Fig. 13. The method includes steps 1400 to 1404.

[0261] Step 1400: Start the vehicle system.

[0262] Optionally, the vehicle terminal is in an on state, and the on state includes at least one of a driving state, an off state, and a standby state.

[0263] Optionally, the co-driver or the main driver starts the vehicle system, turns on the vehicle screen, and determines the screen status of the main driver area, the central control area, and the co-driver area. The screen status includes the screen on status and the screen off status.

[0264] Step 1401: Detect the passenger operating system area.

[0265] The passenger operating system area includes the passenger use area in the central control area and / or the passenger area.

[0266] Optionally, detect whether the co-pilot area and the co-pilot area are in the screen-on state.

[0267] In response to the passenger seat usage area and / or the passenger seat area being in the screen-on state, the following steps 1401 to 1404 are executed.

[0268] Step 1402: Determine whether there is a new area in the passenger seat operating system area.

[0269] If there is a new area, execute the following step 1403.

[0270] If there is no new area, execute the following step 1404.

[0271] Step 1403: Control the display mode of the newly added area to be the same as the display mode of the passenger area.

[0272] The implementation process of this step is the same as that of the above step 1110 and will not be repeated here.

[0273] In this embodiment of the present application, a central control area and a passenger area are provided on the vehicle screen, creating a passenger area in the central control area that can be controlled by the passenger. The vehicle terminal freely controls the display mode of the target screen area, which includes both the passenger area and the passenger area. In anti-peeping mode, the target screen area effectively prevents the primary driver from viewing the content displayed, minimizing driving interference. In shared mode, the target screen area ensures that both the passenger and primary driver can view the target screen simultaneously, achieving a dynamic anti-peeping effect.

[0274] Step 1404 , controlling the display mode of the newly added area to be opposite to the display mode of the passenger area.

[0275] The implementation process of this step is the same as that of the above step 1110 and will not be repeated here.

[0276] In this embodiment of the present application, a central control area and a passenger area are provided on the vehicle screen, creating a passenger area in the central control area that can be controlled by the passenger. The vehicle terminal freely controls the display mode of the target screen area, which includes both the passenger area and the passenger area. In anti-peeping mode, the target screen area effectively prevents the primary driver from viewing the content displayed, minimizing driving interference. In shared mode, the target screen area ensures that both the passenger and primary driver can view the target screen simultaneously, achieving a dynamic anti-peeping effect.

[0277] In an optional embodiment, the vehicle terminal automatically monitors the increase in the passenger area within the central control area and adaptively adjusts the display mode of the passenger area based on the monitoring results, effectively improving the flexibility of the vehicle terminal's overall anti-peeping effect.

[0278] FIG15 is a flowchart of an in-vehicle display method provided by another exemplary embodiment of the present application, which is illustrated by applying the method to an in-vehicle terminal with an in-vehicle screen. As shown in FIG15 , the method includes:

[0279] Step 1500: When a first condition is met, determine whether the display mode of the target screen area is switched to a sharing mode.

[0280] Optionally, the first condition includes at least one of the following conditions:

[0281] Turn off the drive unit;

[0282] The content of the electronic rearview mirror is projected onto the passenger area;

[0283] Enable autonomous driving above level L2, where L2 is semi-autonomous driving.

[0284] Under this condition, the driver can view the content displayed in the target screen area without having to focus their full attention on driving the vehicle. If the target screen area's original display mode is anti-peeping mode, the vehicle terminal switches the target screen area's display mode from anti-peeping mode to sharing mode; if the target screen area's original display mode is sharing mode, the vehicle terminal maintains the target screen area's display mode.

[0285] Step 1510: If the second condition is met, determine whether the display mode of the target screen area is switched to the anti-peeping mode.

[0286] The second condition includes at least one of the following:

[0287] Start the drive device;

[0288] The content of the electronic rearview mirror is not projected onto the passenger area;

[0289] Autonomous driving above level L2 is not enabled.

[0290] Under this condition, the primary driver is fully focused on driving the vehicle, and the display content in the target screen area needs to be blocked. In other words, anti-peeping mode is activated. If the target screen area is originally in shared mode, the vehicle terminal switches the display mode of the target screen area from shared mode to anti-peeping mode. If the target screen area is originally in anti-peeping mode, the vehicle terminal maintains the display mode of the target screen area.

[0291] The driving device in steps 1500 and 1510 is used to control the vehicle terminal to be in an on or off state. Optionally, the driving device is implemented as any one of a fuel engine, an electric engine, a hydrogen engine, a wind engine, a hydraulic engine, a solar engine, and a nuclear engine.

[0292] The electronic rearview mirror in the above steps 1500 and 1510 is an indirect vision device that obtains a preset vision range by using a vision detection system composed of a camera component and a processor in the vehicle terminal.

[0293] The above steps 1500 and 1510 may also be implemented as the flowchart shown in FIG16 , which includes steps 160 to 165 .

[0294] Step 160: Start the vehicle terminal.

[0295] Start the vehicle terminal.

[0296] Optionally, the driving device in the above-mentioned vehicle-mounted terminal is used to control the vehicle-mounted terminal to be in an open state.

[0297] Step 161: Control the passenger area to be in anti-peeping mode.

[0298] The in-vehicle terminal adjusts the display mode of the passenger area to anti-peep mode.

[0299] Step 162: Determine whether the vehicle-mounted terminal turns off the engine.

[0300] In the embodiment of the present application, the engine is implemented as a fuel engine.

[0301] If the engine of the vehicle terminal is in the on-board state, the following step 163 is executed.

[0302] If the engine of the vehicle terminal is in the off state, the following step 165 is executed.

[0303] Step 163: Determine whether the electronic rearview mirror content of the vehicle terminal is projected onto the central control area.

[0304] If it is detected that the content of the electronic rearview mirror is not projected onto the central control area, the following step 164 is executed.

[0305] If it is detected that the content of the electronic rearview mirror is projected onto the central control area, the following step 165 is executed.

[0306] Step 164: Determine whether the vehicle-mounted terminal is enabled for automatic driving or semi-automatic driving.

[0307] If it is detected that the vehicle-mounted terminal turns on automatic driving or semi-automatic driving, step 161 is executed.

[0308] If it is detected that the vehicle-mounted terminal has not started automatic driving or semi-automatic driving, step 165 is executed.

[0309] Step 165 , control the display mode of the central control area to be in sharing mode.

[0310] Optionally, the vehicle terminal adjusts the display mode of the passenger area to a shared mode.

[0311] In this embodiment of the present application, a central control area and a passenger area are provided on the vehicle screen, creating a passenger area in the central control area that can be controlled by the passenger. The vehicle terminal freely controls the display mode of the target screen area, which includes both the passenger area and the passenger area. In anti-peeping mode, the target screen area effectively prevents the primary driver from viewing the content displayed, minimizing driving interference. In shared mode, the target screen area ensures that both the passenger and primary driver can view the target screen area simultaneously, achieving a dynamic anti-peeping effect.

[0312] In combination with the above four embodiments, a display method of a vehicle-mounted screen provided by the present application is introduced in detail. The following is a detailed introduction to the display principle of a vehicle-mounted screen provided by the present application.

[0313] The above content involves three levels of anti-peeping, including the first anti-peeping level, the second anti-peeping level and the third anti-peeping level. The target screen area has different shared viewing angles for the main driver at different anti-peeping levels. As shown in Figure 17, taking the third anti-peeping level and the second anti-peeping level as an example, the anti-peeping effect of the third anti-peeping level is higher than that of the second anti-peeping level. Among them, the display content in the co-pilot area 1700 relative to the shared viewing angle of the main driver at the third anti-peeping level can be seen in the dotted part, and the display content in the co-pilot area 1700 relative to the shared viewing angle of the main driver at the second anti-peeping level can be seen in the solid part. Among them, the original outgoing light of the co-pilot area display module is adjusted to be deflected to the first angle at the third anti-peeping level, and the original outgoing light of the co-pilot area display module is adjusted to be deflected to the second angle at the second anti-peeping level. Please refer to the dotted line part in Figure 17 for the original outgoing light of the co-pilot area module.

[0314] Combining the above content and Figure 18 for explanation, with the center of the vehicle screen as the origin, a coordinate system 180 as shown in Figure 18 is established. In the coordinate system 180 shown in Figure 18, A is the number of pixels in the main driver's area, A is the number of pixels in the non-privacy zone in the dynamically adjusted area, and the spatial coordinates of the privacy zone are calculated based on the passenger area. Among them, the main driver's area includes the instrument area and the non-passenger driver's area in the center console area, and the passenger area includes the passenger driver's area in the center console area and the passenger driver area. Optionally, the total length of the vehicle screen is 1500mm, the distance between the main driver and the passenger's visible area is 800mm, the distance between the main driver and the passenger and the screen is 500mm, the distance between the main driver and the passenger is 400mm, and the pupil distance between the main driver and the passenger is 60mm. Determine the lengths of the first line segment, the second line segment, and the third line segment. The first line segment is used to indicate the distance from the left edge of the main driving area to the right edge of the main driver's visual area, such as: AB is recorded as the first line segment; the second line segment is used for the distance from the right edge of the main driver's visual area to the center of the vehicle screen, such as: BO is recorded as the second line segment; the third line segment is used to indicate the distance from the left edge of the main driving area to the left edge of the dynamic adjustment area, such as: AC is recorded as the third line segment.

[0315] Optionally, the anti-peeping adjustment display panel has multiple display channels, and the multiple display channels include a first display channel and a second display channel.

[0316] Obtain a first screen resolution of the non-peeping area in the first display channel; and determine a first boundary coordinate between the non-peeping area and the anti-peeping area in the first display channel based on the first screen resolution, the total length of the vehicle-mounted screen, and the third line segment.

[0317] Optionally, the first boundary coordinate of the first display channel is calculated based on the following formula 1, that is, the first boundary coordinate is the product of the third line segment and the ratio of the first screen resolution and the total length of the vehicle screen.

[0318] Formula 1: First boundary coordinate / screen resolution = third line segment / total length of the vehicle screen;

[0319] Since there is a certain distance between the first display channel and the second display channel, the distance mapped to the second display channel on the outgoing light ∠θ is the distance of the dynamic adjustment area.

[0320] Obtain a second screen resolution of the non-peeping area in the second display channel; and determine a second boundary coordinate between the non-peeping area and the anti-peeping area in the second display channel based on the second screen resolution, the total length of the vehicle-mounted screen, and the third line segment.

[0321] Optionally, the second boundary coordinates of the second display channel are calculated based on the following formula 1.

[0322] Formula 2: Second boundary coordinate / second screen resolution = (third line segment + length of dynamic adjustment area) / total length of the vehicle screen;

[0323] The first screen resolution and the second screen resolution may be the same resolution or different resolutions, which is not limited in this application.

[0324] Exemplarily, when the resolution of the vehicle-mounted screen is a first resolution and a second resolution, the corresponding boundaries of the non-privacy protection area and the privacy protection area are different.

[0325] First, the implementation method of the display device for the vehicle screen is introduced.

[0326] In the following embodiments, the vehicle-mounted screen is implemented as an LCD screen as an example for description. The vehicle-mounted screen can also be implemented with other materials, which is not limited in this application.

[0327] Optionally, as shown in Figure 19, the vehicle screen 1900 includes an anti-peeping backlight layer 1903, an anti-peeping adjustment panel layer 1902, and a liquid crystal display layer 1901. The following briefly introduces the anti-peeping backlight layer, the anti-peeping adjustment panel layer, and the liquid crystal display layer.

[0328] The privacy backlight layer provides privacy backlight output. The privacy direction can be horizontal, and the light output angle range is within a preset angle range, such as: the preset angle range is ±25°. The backlight can be side-incident backlight, or it can be a direct-type light-emitting diode (LED) backlight, or other backlight forms. Optionally, the privacy backlight layer can achieve a light output angle of ±25° through a prism film design, the attachment of a privacy film, etc., and different privacy protection angles can be optimized through the design of film layers such as prism films and privacy films.

[0329] The privacy adjustment panel layer can switch between privacy and shared modes. It includes an upper substrate, a lower substrate, a liquid crystal layer between the two substrates, and electrodes and control circuitry for driving the liquid crystal. The privacy adjustment panel layer is implemented as a liquid crystal grating structure, consisting of an ITO layer, an insulating layer (e.g., a PVX layer), and an LC layer. It also includes a liquid crystal alignment layer, an auxiliary display layer, a PS structure to support the cell thickness, and frame sealant around the panel. The pixel ITO is a strip-shaped structure, the Com ITO is a planar electrode, and the liquid crystal fills the cell cells. Optionally, the display viewing angles of the passenger and center console areas can be controlled by voltage control. This ensures that the driver can see the desired screen area even when adjusting the seat forward or backward. The specific implementation principle is: the pixel electrode period is set to the first period, such as any value between 3 and 10 μm, the electrode width is set to a preset width, such as any value between 1 and 5 μm, and the cell gap value range is within a preset range, such as between 3 and 7 μm. The pixel ITO is loaded with a periodic square wave signal, with a period of one hertz (e.g., 60Hz or other frequency values). The maximum and minimum values ​​of the square wave signal are denoted as max and min, respectively. The com ITO can be a DC signal, with the DC signal value denoted as com. The signal magnitude must satisfy Vop = max - com = com - min, where Vop is the liquid crystal drive voltage. As the drive voltage increases, the shared viewing angle increases, meeting the requirements of different viewing angles.

[0330] The liquid crystal display layer is used to provide display information, including upper and lower polarizers and a liquid crystal box located between the polarizers. The transmission axis direction of the lower polarizer is required to be consistent with the initial orientation direction of the liquid crystal in the anti-peep-sharing switching layer. There are no restrictions on the liquid crystal display mode or resolution.

[0331] In an optional embodiment, in order to better achieve the coordination between the anti-peeping adjustment panel layer and the liquid crystal display panel layer, and to meet the requirement that the horizontal direction of the scene is the anti-peeping direction, the anti-peeping adjustment panel layer is arranged with at least two electrodes and at least two liquid crystals, wherein the at least two liquid crystals are distributed between the at least two electrodes, the arrangement direction of the at least two electrodes is horizontal, the extension direction is vertical, and the orientation directions of the at least two liquid crystals are perpendicular to each other or parallel to each other; optionally, the orientation direction is parallel to the at least two electrodes or perpendicular to the at least two electrodes. As shown in Figure 20, Figure 20 shows a schematic diagram of the arrangement of liquid crystals and electrodes provided by an exemplary embodiment of the present application. Among them, the arrangement direction of at least two electrodes 2000 is horizontal, the extension direction is vertical, the at least two liquid crystals 2001 and the at least two electrodes 2000 are perpendicular to each other, presenting the arrangement of the left frame diagram 200 of Figure 20, and the at least two liquid crystals 2001 and the at least two electrodes 2000 are parallel to each other, presenting the arrangement of the right frame diagram 201 of Figure 20.

[0332] Optionally, for the implementation principle of controlling the target screen area of ​​the vehicle screen to be in one of the multiple display modes, please refer to the following steps S1 to S2.

[0333] Step S1: Control the target screen area to be in anti-peeping mode.

[0334] Optionally, the vehicle screen includes a liquid crystal display panel layer and an anti-peeping adjustment panel layer. The anti-peeping adjustment panel layer is arranged with at least two electrodes and at least two liquid crystals. For the specific arrangement of the at least two electrodes and at least two liquid crystals, please refer to the above content and will not be repeated here.

[0335] Optionally, the vehicle screen includes a main driver area, a central control area and a co-driver area, and the central control area includes an area for the co-driver.

[0336] From the above, it can be seen that when the vehicle terminal is in driving state, it is necessary to dynamically adjust the display mode of the co-pilot operable area (target screen area) to anti-peeping mode or sharing mode. Among them, the target screen area includes the co-pilot use area and / or the co-pilot area.

[0337] Optionally, different voltage drive signals correspond to different viewing angles. In an illustrative example, as the drive voltage increases, the larger the viewing angle of the primary driver, the larger the shared viewing angle of the target screen area. As shown in FIG20 , FIG21 illustrates the viewing angle range of the target screen area under different voltages. In graph 2100 , the horizontal axis indicates the shared angle of the target screen area, and the vertical axis indicates the display brightness value of the target screen area. As can be seen from graph 2100 , as the drive voltage increases, the lower the brightness of the screen area, the smaller the shared angle.

[0338] Optionally, a target anti-peeping sub-mode is determined from a plurality of anti-peeping sub-modes, and the anti-peeping mode is applied to the target screen area. As described in step 500 above, different anti-peeping sub-modes require different anti-peeping levels to be set for different areas within the target screen area. Different anti-peeping levels correspond to different display brightnesses, and in this embodiment, the display brightness is controlled by a voltage drive signal, that is, different voltage drive signals drive the liquid crystal display panel layer to different display brightnesses.

[0339] In response to controlling the target screen area to be in the target anti-peeping sub-mode, corresponding voltage driving signals are applied to the anti-peeping adjustment panel layer of the corresponding area according to the anti-peeping levels of different areas in the target anti-peeping sub-mode, so that at least two liquid crystals corresponding to different sub-areas in the target screen area are tilted to different degrees along the direction of the electric field lines;

[0340] The display brightness of the liquid crystal display panel layer corresponding to the different sub-areas is determined according to the tilting degrees of at least two liquid crystals corresponding to the different sub-areas in the target screen area.

[0341] Schematically, the target anti-peeping sub-mode is: the upper area of ​​the central control area is at the third anti-peeping level, the area other than the upper area of ​​the central control area is at the second anti-peeping level, and the co-pilot area is at the first anti-peeping level.

[0395] The control module is configured to control the passenger seat area to be in the sharing mode when detecting that the passenger seat area is added to the central control area and the passenger seat area is in the sharing mode.

[0396] In an optional embodiment, as shown in FIG24 , the apparatus further includes a determination module 2301 .

[0410] In summary, the display device for the vehicle screen provided in the embodiment of the present application sets a central control area and a co-pilot area in the vehicle screen, and there is a co-pilot use area in the central control area that can be controlled by the co-pilot. The display mode of the target screen area is freely controlled by the vehicle terminal, and the target screen area includes the co-pilot area and the co-pilot use area. In the anti-peeping mode, it can effectively prevent the main driver from seeing the display content in the target screen area, reducing the driving interference to the main driver; in the sharing mode, the target screen area can ensure that the co-pilot and the main driver can watch the target screen area at the same time, thereby achieving a dynamic anti-peeping effect.

[0411] In an optional embodiment, the switching between anti-peeping mode and sharing mode is realized only in the passenger seat area in the central control area, and the remaining screen areas in the central control area are in normal display mode. On the premise that the main driver can still view the visual information in the central control area, the passenger seat area has visual flexibility and can control whether it is in anti-peeping mode, thereby achieving the effect of dynamically adjusting the anti-peeping display and effectively improving the driving safety of the main driver.

[0412] In an optional embodiment, different anti-peeping levels are set for the vehicle screen, which not only protects the privacy of the co-driver operating the target screen area, but also ensures that the visual information of the target screen area cannot be read by the main driver, effectively improving the driving safety of the main driver.

[0413] In an optional embodiment, different anti-peeping levels are set. First, it can be directly reflected in the display brightness. While protecting the main driver from peeping, it prevents the display brightness of the target screen area from dropping too low, which will have a certain impact on the browsing experience of the co-driver; second, based on the relative value of the change in light intensity value that can occur in the main driver's peripheral vision range, the accurate value of the target screen area that cannot be seen by the main driver is reasonably determined, thereby further improving the anti-peeping effect on the main driver.

[0414] In an optional embodiment, different areas within the target screen area are determined based on the position of the main driver / co-driver and the real-time ambient light intensity of the area, providing certain support for subsequent further zoning and anti-peeping.

[0415] In an optional embodiment, different anti-peeping sub-modes are set for different areas of the target screen area. When controlling different areas, the anti-peeping mode is dynamically switched, which not only improves the comprehensiveness of the anti-peeping effect, but also improves the anti-peeping flexibility.
