[0008] According to an embodiment of the present application, the display control circuit determines that there is no passenger on the front passenger seat of the motor vehicle if the length of time after the motor vehicle is started that the front passenger seat has no passenger exceeds a preset threshold.

[0011] According to an embodiment of the present application, when controlling at least a portion of the non-driver's display area to display low-power consumption data, the display control circuit is configured to: when the non-driver's display area only includes the passenger display area, control the passenger display area to display low-power consumption data, and control the driver's display area to display corresponding display data, or control the driver's display area to display corresponding display data of the driver's display area and the passenger display area; and when the non-driver's display area includes the passenger display area and the central control display area: control the central control display area and the passenger display area to display low-power consumption data, and control the driver's display area to display corresponding display data, or control the driver's display area to display the corresponding display data of the driver's display area and at least one of the central control display area and the passenger display area, or control the passenger display area to display low-power consumption data, and control the driver's display area and the central control display area to display corresponding display data, or control the central control display area and the driver's display area to jointly display the display data corresponding to the driver's display area.

In this way, the display power consumption and / or processor power consumption can be reduced, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] FIG1 shows a schematic diagram of an onboard display screen in a motor vehicle according to an embodiment of the present application.

[0026] As shown in FIG1 , the in-vehicle display screen has a single screen, and it can span the main and co-pilot seats of the motor vehicle, so that passengers on both the main and co-pilot seats can obtain information from the in-vehicle display screen and optionally interact with it.

[0027] The display area on the vehicle display screen can be divided into multiple display areas, and the sizes of the multiple display areas can be the same or different, so that appropriate content can be displayed in different display areas according to different needs. For example, the display area corresponding to the main driver's position on the vehicle display screen (hereinafter referred to as the main driver's display area) can display basic vehicle information and instrument information such as driving data, thereby providing an intuitive reference for the driver's driving behavior; the display area adjacent to the main driver's display area on the vehicle display screen (hereinafter referred to as the non-main driver's display area) can display navigation information and can also realize some in-vehicle entertainment functions, such as video playback function, music playback function and broadcast function. Optionally, the non-main driver's display area may include the central control display area and the co-driver's display area, or may also include other display areas, or may only include the co-driver's display area, which can be designed according to actual needs.

[0028] Typically, in current designs, both the driver's seat display area and the non-driver's seat display area are displayed simultaneously, meaning the display control circuit of the vehicle-mounted display screen controls the display screen to remain displayed. However, the inventors of this application have noted that when the passenger seat is unoccupied, the display of the passenger seat display area becomes less necessary, and the driver may not pay much attention to the display content in the central control display area while driving. Therefore, in order to reduce display power consumption, it is possible to consider dynamically controlling the display of the passenger seat display area and / or the central control display area based on whether the passenger seat is occupied. For example, when the passenger seat changes from unoccupied to occupied, the corresponding display operation of the passenger seat display area is activated; when the passenger seat changes from occupied to unoccupied, the corresponding display operation of the passenger seat display area is disabled.

[0029] Furthermore, to better implement zoning control of the display operations of the vehicle display screen, embodiments of the present application also consider utilizing multiple operating systems to control different display zones. For example, if the driver's seat display zone needs to remain displayed at all times, a different operating system (e.g., one with greater reliability and stability) can be used to control the display operations than the non-driver's seat display zones.

[0030] FIG2 shows a schematic structural diagram of a display system in a motor vehicle according to an embodiment of the present application.

[0031] As shown in FIG2 , the display system 200 includes an in-vehicle display screen 210 and a display control circuit 220. The in-vehicle display screen may be the in-vehicle display screen shown in FIG1 , which includes a single screen divided into a driver's seat display area Z1 and a non-driver's seat display area Z2, wherein the non-driver's seat display area includes at least a passenger seat display area.

[0032] The display control circuit 220 may include various circuit components for driving the display panel, and at least a portion thereof may be integrated with the display panel into a single module. The display control circuit 220 may be configured to generate first and second drive signals for the driver's display area and non-driver's display area on the vehicle display screen, respectively driving the display operations of the driver's display area and the non-driver's display area.

[0033] It should be noted that each of the first driving signal and the second driving signal here is actually a group of signals, such as a row driving signal and a column driving signal for each row of pixels and each column of pixels of a display panel of a display screen.

[0034] As mentioned above, in order to reduce display power consumption, the display control circuit can be configured to: when it is determined that there is no passenger on the passenger seat of the motor vehicle after the motor vehicle is started, control the display operation of the non-main passenger display area in a low power consumption mode. For example, the display control circuit can obtain a sensor signal from a sensor (e.g., an image sensor, a gravity sensor, etc.) and determine whether there is someone on the passenger seat based on the sensor signal. Optionally, the display control circuit can determine that there is no passenger on the passenger seat of the motor vehicle only when it is determined that the length of time that there is no passenger on the passenger seat after the motor vehicle is started exceeds a preset threshold, so as to improve the accuracy of the detection and avoid frequent operation of the vehicle display screen caused by the passenger on the passenger seat getting off the vehicle immediately after getting on the vehicle.

[0035] In addition, the display control circuit is further configured to: when it is determined that there is someone on the passenger seat when there is no passenger on the passenger seat, switch to controlling the display operation of the non-pilot display area in normal mode.

[0036] Furthermore, the display control circuit may optionally include a timing controller 220-1 and a driving circuit 220-2. For example, the timing controller may generate a first timing signal T1 and a second timing signal T2, and the driving circuit 220-2 may drive the display operations of the driver's display area and the non-driver's display area based on the first timing signal and the second timing signal, respectively.

[0037] It should be noted that each of the first timing signal T1 and the second timing signal T2 is actually a group of signals provided to the driving circuit, such as various start signals, various clock signals and / or reset signals.

[0038] Optionally, the timing controller can obtain a standard image signal or video signal (including multiple image frames), i.e., a data signal, from the outside, and convert the standard image signal or video signal into a timing signal required for driving specific rows and columns of the display panel (forming a vehicle-mounted display screen), and send it to the driving circuit so that the driving circuit can generate a driving signal to display the display data on the vehicle-mounted display screen.

[0039] The driving circuit 220-2 may include a source driving circuit of a gate driving circuit for a vehicle display screen, etc., to generate a first driving signal based on the first timing signal T1 to drive the display operation of the main driver display area and to generate a second driving signal based on the second timing signal T2 to drive the display operation of the non-main driver display area.

[0040] Optionally, the driver circuit includes one or more driver chips, each of which corresponds to display operations for at least a portion of the driver's seat display area or the non-driver's seat display area. For example, a first driver chip and a second driver chip are used to drive the display operations for the driver's seat display area, and a third driver chip and a fourth driver chip are used to drive the display operations for the non-driver's seat display area. To disable the display operation of a particular display area, the driver chip corresponding to that display area can be deactivated, or the timing controller can be disabled from providing timing signals to that driver chip.

[0041] As mentioned above, the partitioned display of the vehicle display screen can be controlled by multiple operating systems to provide reliability of display control and avoid mutual interference between displays in different display areas. For example, in order to achieve multi-operating system control, the display system of the vehicle display screen may include a processor system (e.g., a system on a chip (SOC)) for overall control, which can be integrated with the timing controller and the drive circuit as part of the display control circuit or be independently provided with the display control circuit. For example, taking the processor system as an SOC as an example, after the vehicle is started, the SOC executes a computer program (which can be stored in various forms) to run a first operating system (e.g., a server system, such as QNX). At this time, the first operating system can trigger the display operation of the main driver's display area, or trigger the display operation of the entire display area of ​​the vehicle display screen, or only start to perform the preparation operation for display but does not control the display operation of any display area. Then, the first operating system can run a virtual machine (QNX virtual machine) and run a virtual operating system (for example, Android system) on the virtual machine. The virtual operating system can correspond to the non-driver display area (at least the passenger display area). In this way, the display operation of the driver display area can be based on the first operating system outputting display-related control signals (for example, data signals and timing control signals) of display data to the timing controller to achieve, and the display operation of the non-driver display area can be based on the second operating system outputting display-related control signals of display data to the timing controller to achieve; or, two or more virtual operating systems can be run on the virtual machine running on the first operating system, such as Linux system and Android system, the Linux system is used for the driver display area and the Android system is used for the non-driver display area, or, the Linux system is used for the driver display area and the first Android system is used for the central control display area, and the second Android system is used for the passenger display area.

[0042] For example, the timing controller can obtain display control-related signals from a virtual operating system (for example, a Linux system or an Android system), such as data signals and timing control signals (for example, at least a part of a clock signal, a synchronization signal, an enable signal, etc.) for display data to be displayed (for example, video image data during normal display) or low-power data in low-power mode (as described later), etc. (for example, in eDP signal format, LVDS signal format), and use them to generate the above-mentioned first timing signal and the above-mentioned second timing signal.

[0043] In addition, since a single timing controller (e.g., in the form of an integrated chip) may not be sufficient for a high lateral resolution of an in-vehicle display (e.g., 10K resolution), two or more timing controllers may be used. In this case, a switch is provided between the timing controllers, and the processor system controls the switching of the switch to achieve cascading of the timing controllers, thereby achieving uniform drive timing for each display area during full-screen normal display.

[0044] The vehicle-mounted display screen can be a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display screen or a miniLED display screen or a MicroLED display screen, etc., wherein the LCD display has a backlight, and the OLED, miniLED, and MicroLED are self-luminous. When the vehicle-mounted display screen is an LCD display screen, since a backlight is also required, the display system can also include a backlight control circuit, and respective backlight sources are set for different display areas, so that when a certain display area is not displayed, the corresponding backlight source is turned off, thereby turning off the backlight display of the display area. The backlight control circuit can drive the backlight source by a backlight control signal provided by the processor system, so that when the display control circuit prohibits the display operation of the central control display area and / or the co-pilot display area, the backlight control circuit controls the backlight source corresponding to the central control display area and / or the co-pilot display area to turn off based on the backlight control signal, thereby turning off the backlight display of the display area.

[0045] As described above, the display system shown in FIG2 can be used to implement partitioned display, so that when it is determined that there is no passenger on the passenger side of the motor vehicle after the motor vehicle is started, the display operation of the non-main driver display area can be controlled in a low power consumption mode.

[0046] Optionally, controlling the display operation of the non-driver's display area in a low power consumption mode may include: prohibiting the display operation of at least a portion of the non-driver's display area, or controlling at least a portion of the non-driver's display area to display low power consumption data.

[0047] The following is a detailed introduction on how to perform partitioned display (including controlling the display operation of the non-driver display area in a low power consumption mode) based on the display system shown in FIG. 2 .

[0048] 3A-3E show schematic diagrams of displays on a vehicle display screen when the display control circuit controls the non-driver's display area in a low power consumption mode, wherein the driver's display area is displayed normally.

[0049] For example, in the case where the non-main driver display area only includes the passenger display area (that is, the display area of ​​the vehicle-mounted display screen is divided into the main driver display area and the passenger driver display area), as shown in Figure 3A, the display operation of the passenger driver display area can be prohibited or the passenger driver display area can be controlled to display low-power data (instead of the image data that should be displayed (for example, entertainment data or interactive information data with other devices, etc.)), and the main driver display area is controlled to display corresponding display data (for example, vehicle-related information or instrument panel data, etc.); or, as shown in Figure 3B, the display operation of the passenger driver display area can be prohibited or the passenger driver display area can be controlled to display low-power data, and the main driver display area can be controlled to display the corresponding display data of the main driver display area and the passenger driver display area (for example, both the instrument panel data and the entertainment data are displayed in the main driver display area). In this way, it can be avoided that the display data of the passenger driver display area cannot be processed in time, such as message reminders.

[0050] For another example, when the non-main driver display area includes the passenger display area and the central control display area (that is, the display area of ​​the vehicle-mounted display screen is divided into the main driver display area, the central control display area and the passenger display area), as shown in Figure 3C, the display operation of the central control display area and the passenger display area can be prohibited or the central control display area and the passenger display area can be controlled to display low-power data, and the main driver display area is controlled to display corresponding display data (for example, instrument panel data); or, as shown in Figure 3D, the display operation of the passenger display area can be prohibited or the passenger display area can be controlled to display low-power data, and the main driver display area and the central control display area can be controlled to display corresponding display data; or, as shown in Figure 3E, the display operation of the passenger display area can be prohibited or the passenger display area can be controlled to display low-power data, and the central control display area and the main driver display area can be controlled to jointly display the corresponding display data of the main driver display area. In this way, the driver's visual experience of viewing the corresponding display data of the main driver display area can be improved, for example, a large-size instrument panel can be seen. Of course, it is also possible to prohibit the display operation of the central control display area and the passenger display area or control the central control display area and the passenger display area to display low power consumption data, and control the main driver display area to display the corresponding display data of the main driver display area and at least one of the central control display area and the passenger display area (not shown); or prohibit the display operation of the passenger display area or control the passenger display area to display low power consumption data, and control the main driver display area and the central control display area to display the corresponding display data of the main driver display area, the central control display area and the passenger display area (not shown), and so on.

[0051] You can choose how to control the non-driver's display area in low-power mode according to actual conditions. Turning off the non-driver's display area can significantly reduce the power consumption of the on-board display. Displaying low-power data in the non-driver's display area can reduce the power consumption of the on-board display to a certain extent. At the same time, the visual experience in the car can be improved by displaying low-power data. For example, low-power data can be a clock, wallpaper, etc. When it comes to changes in the display content of any display area (for example, the driver's display area shown in Figure 3B needs to display content that should be displayed jointly by the driver's display area and the co-driver's display area, or the display content corresponding to the driver's display area is displayed in the driver's display area and the central control display area), the current frame image can be re-rendered at the SOC of the display system to make it conform to the properties of the display area to be displayed (for example, resolution, aspect ratio, etc.) so as to control the display operation of the display area via the timing controller and the drive circuit.

[0052] 4A-4D show a schematic diagram of a system structure when the display control circuit includes a single timing controller (a first timing controller) and a schematic diagram of a system operation for controlling the non-driver display area in a low power consumption mode.

[0053] The vehicle display screen shown in Figure 4A includes two parts: the main driver display area and the co-driver display area. The vehicle display screen shown in Figures 4B-4D includes three parts: the main driver display area, the central control display area, and the co-driver display area.

[0054] As previously mentioned, the driver's seat display area and the non-driver's seat display area can be controlled by multiple operating systems, and the non-driver's seat display area can correspond to one or more virtual operating systems (for example, Android system) running on the operating system of the processor system of the display system. In this case, the driver's seat display area can correspond to another operating system (for example, QXN system or virtual Linux system (hereinafter used as an example)) running on the virtual machine.

[0055] More specifically, the display control circuit can be configured to prohibit the display operation of the central control display area and / or the passenger display area by prohibiting the first timing controller from outputting at least a portion of the second timing signal corresponding to the central control display area and / or the passenger display area to the driver circuit. Alternatively, the display control circuit can be configured to control the central control display area and / or the passenger display area to display low power data by causing the first timing controller to output at least a portion of the second timing signal corresponding to the central control display area and / or the passenger display area to the driver circuit based on the display control-related signal of low power data.

[0056] For example, when the display control circuit prohibits the first timing controller from outputting at least a portion of the second timing signal to the driver circuit, the virtual operating system corresponding to the non-driver display area can be controlled to stop running; or when the central control display area and the passenger display area correspond to the same virtual operating system (that is, the non-driver display area corresponds to one virtual operating system), the virtual operating system is controlled to keep running and stop outputting display control-related signals (for example, data signals and timing control signals) of the display data corresponding to the central control display area and / or the passenger display area (during normal display) to the first timing controller. Similarly, when the first timing controller outputs at least a portion of the second timing signal to the driver circuit based on the display control-related signal of the low-power data, the virtual operating system can run and output display control-related signals of the low-power data corresponding to the central control display area and / or the passenger display area to the first timing controller.

[0057] Optionally, when controlling the virtual operating system corresponding to the non-driver's display area to stop running, the display control circuit can be configured as follows: when the non-driver's display area only includes the passenger display area, when the passenger display area corresponds to the first virtual operating system, the first virtual operating system is controlled to stop running; or when the non-driver's display area includes the passenger display area and the central control display area, when the passenger display area corresponds to the first virtual operating system and the central control display area corresponds to the second virtual operating system, the first virtual operating system and / or the second virtual operating system are controlled to stop running. By controlling the virtual operating system to stop running, the power consumption of the processor system can be reduced and the resources of the processor system can be released. By controlling the virtual operating system to stop running, a snapshot of the virtual operating system can be taken. The snapshot can be used to maintain the state of the virtual operating system, including the state of the application software within the virtual operating system. When it is necessary to resume the operation of the virtual operating system, the state of the virtual operating system can be quickly restored by restoring the snapshot. By controlling the virtual operating system to stop running, the virtual operating system can be shut down. When it is necessary to resume the operation of the virtual operating system, the virtual operating system can be started.

[0058] For example, in FIG4A , when the display operation of the passenger display area is prohibited, the corresponding virtual operating system may not output the display control-related signals of the display data corresponding to the passenger display area to the first timing controller TCON. Therefore, the first timing controller TCON cannot output the second timing signal T2 to the driving circuit (for example, the two driving chips IC3-IC4 corresponding to the passenger display area). In addition, the driving circuit cannot output the second driving signal based on the second timing signal T2, so the passenger display area does not display. At this time, the virtual operating system can be stopped, for example, in a dormant state, or a snapshot of the virtual operating system can be taken to save the current state data of the virtual operating system. In addition, when the vehicle display screen is an LCD display screen, the processor system can also control the backlight corresponding to the passenger display area to turn off. When the backlight corresponding to the passenger display area is turned off, the first timing controller TCON can also output the display control-related signals of the display data corresponding to the passenger display area. However, due to the lack of a backlight, the display data of the passenger display area may not be perceived by the user. However, generally speaking, considering power consumption, when the backlight corresponding to a display area is turned off, the timing controller will try not to output the display control-related signals of the display data of the display area to the driving circuit.

[0059] Alternatively, the virtual operating system may also output display control-related signals (e.g., data signals or timing control signals) of low-power data (e.g., black screen data, clock, wallpaper image data, etc.) to the first timing controller TCON, so that the first timing controller TCON outputs a second timing signal T2 to the driving circuit (e.g., the two driving chips IC3-IC4 corresponding to the co-pilot display area), so that the driving circuit can output a second driving signal based on the second timing signal, thereby displaying the low-power display data in the co-pilot display area.

[0060] In the example shown in Figure 4A, the main driver's display area is displayed normally. For example, the Linux system corresponding to the main driver's display area can output the display control related signals of the display data corresponding to the main driver's display area (for example, instrument panel data, game scene screen, etc.) to the first timing controller TCON, so that the first timing controller TCON outputs the first timing signal T1 to the driving circuit (for example, the two driving chips IC1-IC2 corresponding to the main driver's display area), so that the driving circuit (for example, the two driving chips IC1-IC2 corresponding to the main driver's display area) can output the first driving signal based on the first timing signal T1, so that it can be displayed normally in the main driver's display area.

[0061] Similarly, in Figure 4B, the central control display area and the passenger display area correspond to the same virtual operating system. When the display operations displayed in both the central control display area and the passenger display area are prohibited or low-power data is displayed, the processing method is similar to that described with reference to Figure 4A. It is only necessary to make the central control display area and the passenger display area equivalent to the passenger display area in Figure 4A.

[0062] In Figure 4B, when the display operation of the passenger display area is prohibited (assuming that only the display operation of the central control display area is generally not prohibited), the virtual operating system may not output the display control related signal of the display data corresponding to the passenger display area to the first timing controller. Therefore, the first timing controller TCON cannot output the part T2-2 of the second timing signal corresponding to the passenger display area to the driving circuit (for example, a driver chip IC4 corresponding to the passenger display area) (the first timing signal T1 for the main driver display area and the part T2-1 of the second timing signal for the central control display area are output normally), and then the driving circuit cannot output the corresponding part of the second drive signal based on the part T2-2 of the second timing signal, so the passenger display area will not display. At this time, the virtual operating system remains running. In addition, when the vehicle display screen is an LCD display screen, the processor system can also control the backlight source of the passenger display area to turn off. In addition, the virtual operating system can similarly output the display control related signal of low-power data to the first timing controller TCON, so that the low-power data is finally displayed in the passenger display area. The description will not be repeated here.

[0063] As shown in FIG4C , the central control display area and the passenger display area correspond to the same virtual operating system. Similar to FIG4B , when the display operation of the passenger display area is prohibited, the virtual operating system may not output the display control-related signals of the display data corresponding to the passenger display area to the first timing controller, so that the passenger display area will not display. At the same time, the operating system corresponding to the main driver's display area can output signals to the first timing controller, so that the first timing controller can provide timing signals for the main driver's display area and the central control display area to the driving circuit (for example, the driver chips IC1-IC3 corresponding to the main driver's display area and the central control display area). Therefore, the driving circuit can drive the data that should be displayed in the main driver's display area (for example, instrument panel data) to be displayed in these two display areas. At this time, the virtual operating systems corresponding to the central control display area and the passenger display area can stop running. In addition, the virtual operating systems corresponding to the central control display area and the passenger display area can similarly output display control-related signals of low-power data to the first timing controller TCON, so that the low-power data is ultimately displayed in the passenger display area. This description will not be repeated here.

[0064] As shown in Figure 4D, the central control display area and the passenger display area correspond to different virtual operating systems. When the display operation of the passenger display area (taken as an example here) is prohibited, the corresponding virtual operating system stops running to stop outputting the display control-related signals of the display data corresponding to the passenger display area to the first timing controller. Therefore, the first timing controller TCON does not output the part T2-2 of the second timing signal corresponding to the passenger display area to the drive circuit, and then the drive circuit (for example, a driver chip IC4 corresponding to the passenger display area) cannot output the corresponding part of the second drive signal based on this part of the second timing signal, so the passenger display area will not display. In addition, the virtual operating system corresponding to the passenger display area can similarly output the display control-related signals of low-power data to the first timing controller TCON, so that the low-power data is finally displayed in the passenger display area. The description will not be repeated here.

[0065] 5A-5F are schematic diagrams showing a system structure when the display control circuit includes two timing controllers (a first and a second timing controller) and a schematic diagram showing the system operation of controlling the non-driver display area in a low power consumption mode.

[0066] In this case, the first timing controller can correspond to the main driver's display area, and the second timing controller can correspond to the non-main driver's display area. The first timing controller and the second timing controller are cascaded via a switch. The second timing controller, as a slave device, needs to obtain a signal from the first timing controller, which is the master device, to ensure that the timing of the timing signals output by both meet the requirements. At this time, the first timing controller can output a first timing signal to the driving circuit (for example, the two driving chips IC1-IC2 corresponding to the main driver's display area), so that the driving circuit can provide a first driving signal to the pixels in the main driver's display area on the display screen, and the second timing controller can output a second timing signal to the driving circuit (for example, the two driving chips IC3-IC4 corresponding to the non-main driver's display area), so that the driving circuit can provide a second driving signal to the pixels in the non-main driver's display area on the display screen.

[0067] Based on this configuration of the two timing controllers, when prohibiting the display operation of the central control display area and / or the passenger display area, the display control circuit can be configured to: disconnect the switch between the first timing controller and the second timing controller to prohibit the second timing controller from outputting the second timing signal to the drive circuit; or keep the switch between the first timing controller and the second timing controller turned on to prohibit the second timing controller from outputting at least a part of the second timing signal corresponding to the central control display area and / or the passenger display area to the drive circuit.

[0068] Alternatively, when controlling the central control display area and / or the passenger display area to display low-power data, the display control circuit is configured to: keep the switch between the first timing controller and the second timing controller turned on, and the second timing controller outputs at least a part of the second timing signal corresponding to the central control display area and / or the passenger display area to the driving circuit based on the display control-related signal of the low-power data.

[0069] The in-vehicle display, as shown in Figures 5A-5B, includes a driver's seat display area and a passenger's seat display area. The driver's seat display area corresponds to an operating system (e.g., QXN or Linux), while the passenger's seat display area corresponds to a virtual operating system (e.g., Android). The switch control signal can come from the system on chip.

[0070] For example, in Figure 5A, when the display operation of the passenger display area is prohibited, the switch between the two timing controllers is disconnected, so the second timing controller TCON2 cannot output the second timing signal T2 (the first timing signal T1 for the main driver display area is normally output) to the driving circuit (for example, the two driver chips IC3-IC4 corresponding to the passenger display area), and thus the driving circuit cannot output the second driving signal based on the second timing signal T2. At this time, the virtual operating system corresponding to the passenger display area can be stopped, for example, in a dormant state, and its current state data (for example, a snapshot) can be saved. In addition, when the vehicle display is an LCD display, the operating system of the display system can also control the backlight corresponding to the passenger display area to turn off.

[0071] Alternatively, in Figure 5B, when the passenger display area is controlled to display low-power data, the switch between the first timing controller TCON1 and the second timing controller TCON2 can be kept turned on, and the second timing controller TCON2 outputs a second timing signal to the driving circuit (for example, the two driving chips IC3-IC4 corresponding to the passenger display area) based on the display control-related signal of the low-power data output by its corresponding virtual operating system and the interaction with the first timing controller through the switch, and the driving circuit can output a second driving signal based on the second timing signal T2.

[0072] As shown in Figures 5C-5F, the vehicle display screen includes three parts: the main driver display area, the central control display area and the co-driver display area, and the main driver display area corresponds to an operating system (for example, QXN system or Linux system), the central control display area and the co-driver display area correspond to the first virtual operating system (Figures 5C-5D), or the central control display area corresponds to the first virtual operating system and the co-driver display area corresponds to the second virtual operating system (Figures 5E-5F).

[0073] In FIG5C , the central control display area and the passenger display area correspond to the same virtual operating system, and are used to output signals to the second timing controller when necessary. Since the second timing controller can control the central control display area and the passenger display area at the same time, when the display operation of the central control display area and / or the passenger display area is prohibited, the switch between the two timing controllers can be disconnected, and the virtual operating system can be stopped, so that the second timing controller does not work, thereby not providing the second timing signal to the drive circuit. In addition, when the vehicle display is an LCD display, the processor system can also control the backlight source of the non-main driver display area to be turned off. In addition, although not shown, the switch can remain on, so that the virtual operating system can output the display control-related signal of the low-power data corresponding to the central control display area and / or the passenger display area to the second timing controller TCON2, so that the low-power data is finally displayed in the central control display area and / or the passenger display area (the other display areas are displayed normally), which will not be repeated here.

[0074] As shown in Figure 5D, the central control display area and the passenger display area correspond to the same virtual operating system, and are used to output signals to the second timing controller when necessary. When the display operation of the passenger display area is prohibited, the switch between the two timing controllers can be maintained to keep the virtual operating system (Android system) running, and the second timing controller TCON2 works, but does not provide the part of the second timing signal corresponding to the passenger display area to the drive circuit (and normally provides the part of the second timing signal corresponding to the central control display area and the first timing signal corresponding to the main driver display area to the drive circuit). In addition, when the vehicle display is an LCD display, the processor system can also control the backlight source of the passenger display area to turn off. In addition, although not shown, the virtual operating system can also output a display control-related signal of low-power data corresponding to the passenger display area to the second timing controller TCON2, so that the low-power data is finally displayed in the passenger display area (the other display areas are displayed normally). This will not be repeated here.

[0075] As shown in Figure 5E, the central control display area corresponds to the first virtual operating system and the passenger display area corresponds to the second virtual operating system. The two virtual control systems can output signals to the second timing controller when needed. Therefore, when the display operation of the central control display area and / or the passenger display area is prohibited, the switch between the two timing controllers can be disconnected, and the first and second virtual operating systems can be stopped. Therefore, the second timing controller does not work, and thus does not provide the second timing signal to the drive circuit. In addition, when the vehicle display screen is an LCD display screen, the processor system can also control the backlight source of the non-main driver display area to be turned off. In addition, although not shown, the switch can remain on, so that the first and / or second virtual operating systems can similarly output display control-related signals of low-power data corresponding to the central control display area and / or the passenger display area to the second timing controller TCON2, so that the low-power data is finally displayed in the central control display area and / or the passenger display area (the other display areas are displayed normally). The description will not be repeated here.

[0076] As shown in Figure 5F, the central control display area corresponds to the first virtual operating system and the passenger display area corresponds to the second virtual operating system. The two virtual control systems can output signals to the second timing controller when needed. Therefore, when the display operation of the passenger display area is prohibited, the switch between the two timing controllers can be maintained, the first virtual operating system (Android system) continues to run, the second virtual operating system stops running, and the second timing controller TCON2 works, but does not provide the part of the second timing signal corresponding to the passenger display area to the driver circuit (and normally provides the part of the second timing signal corresponding to the central control display area and the first timing signal corresponding to the main driver display area to the driver circuit). In addition, when the vehicle display is an LCD display, the processor system can also control the backlight source of the passenger display area to turn off. In addition, although not shown, the second virtual operating system can similarly output a display control-related signal of low-power data corresponding to the passenger display area to the second timing controller TCON2, so that the low-power data is finally displayed in the passenger display area (the other display areas are displayed normally). The description will not be repeated here.

[0077] 6A-6B show a schematic diagram of a system structure when the display control circuit includes three timing controllers and a schematic diagram of a system operation for controlling the non-driver's display area in a low power consumption mode.

[0078] In Figures 6A-6B, three timing controllers correspond to the driver's display area, the center console display area, and the passenger display area, respectively, and include two switches to cascade the three timing controllers. Figure 6A shows the timing controller corresponding to the driver's display area as the master device (M), and Figure 6B shows the timing controller corresponding to the center console display area as the master device.

[0079] When prohibiting the display operation of the central control display area and / or the passenger display area, the display control circuit can be configured to: disconnect the switch between the timing controller corresponding to the central control display area and / or the passenger display area and other timing controllers to prohibit outputting at least a part of the second timing signal corresponding to the central control display area and / or the passenger display area to the driving circuit.

[0080] In addition, when controlling the non-driver display area to display low-power data, the display control circuit is configured to: keep the switches between the three timing controllers turned on, and the timing controllers corresponding to the central control display area and / or the passenger display area output at least a part of the second timing signal corresponding to the central control display area and / or the passenger display area to the driving circuit based on the display control related signal of the low-power data.

[0081] For example, as shown in FIG6A, when the display operation of the central control display area and the passenger display area is prohibited, the two switches SW1 and SW2 can be disconnected, so that the second timing controller and the third timing controller cannot obtain signals from the first timing controller, so that the second timing controller and the third timing controller do not output timing signals (second timing signals) to the drive circuit. Similarly, although not shown, when the display operation of the passenger display area is prohibited, the second switch SW2 can be disconnected, so that the second timing controller can obtain signals from the first timing controller, but the third timing controller cannot obtain signals from the second timing controller, so that the second timing controller can output a timing signal (a portion of the second timing signal corresponding to the central control display area) to the drive circuit and the third timing controller does not output a timing signal (a portion of the second timing signal corresponding to the passenger display area) to the drive circuit.

[0082] For another example, as shown in FIG6B , since the second timing controller corresponding to the central control display area serves as the master device, the second timing controller needs to remain operational, so the central control display area maintains display (normal display data or low-power data), and generally the driver's side display area should also display normally (receiving signals from the second timing controller serving as the master device). When the display operation of the passenger side display area is prohibited, the second switch SW2 between the second timing controller and the third timing controller can be disconnected, so that the third timing controller cannot obtain a signal from the second timing controller, and thus the third timing controller does not output a timing signal (the portion of the second timing signal corresponding to the passenger side display area) to the drive circuit.

[0083] Similar to the previous example, when controlling the central control display area and / or the co-pilot display area to display low-power data, the two switches SW1 and SW2 are closed, that is, the three timing controllers are all working normally, but the second and / or third timing controllers need to obtain the display control related signals of the low-power data from the corresponding virtual operating system.

[0084] In addition, the correspondence between the three timing controllers and the operating system can also be determined as follows, for example, the first timing controller corresponds to the first operating system; the second timing controller corresponds to the first virtual operating system, and the third timing controller corresponds to the second virtual operating system; or, the second timing controller and the third timing controller both correspond to the first virtual operating system.

[0085] It should be noted that the above reference Figures 4A-6B schematically describe various exemplary system structure diagrams, but this is only shown as an example and not a limitation of the present application. Other structures may exist on this basis, which can define different correspondences between the virtual operating system, timing controller, driver chip and / or each display area.

[0086] In addition, the pixels of the display panel of the display screen can be controlled on a half-screen basis to achieve the effect of controlling the main driver's display area, the central control display area, and the passenger driver's display area. For example, when it is necessary to prohibit the display operation of the central control display area and the passenger driver's display area or control them to display low-power data, the display operation of the display area of ​​the right half screen can be turned off or controlled to display low-power data, and for the display area of ​​the left half screen, the normal display operation of the area corresponding to the main driver's display area is controlled, and the display operation of the area corresponding to the remaining part is turned off or low-power data is displayed. For another example, when it is necessary to prohibit the display operation of the passenger driver's display area or control it to display low-power data, the display operation of the display areas of the left and right half screens can be maintained, and the normal display operation of the area corresponding to the central control display area of ​​the right half screen is controlled, and the low-power data is displayed in the area corresponding to the remaining part.

[0087] For example, if the overall horizontal resolution of an on-board display is 7680 pixels, the display area only needs to display the first 2560 columns of pixels for the driver's reference as the main driver's display area. While turning off the backlight of the right half of the screen or not outputting a drive signal to it, the virtual system can output 2560 display data + 1280 low-power data to the left half of the screen, thereby displaying 1 / 3 of the left screen. In this case, according to the correspondence between the virtual control system, the timing controller, and the drive circuit, the virtual control system can be reasonably configured to control the half-screen display area separately to achieve the effect of controlling the main driver's display area, the center console display area, and the front passenger display area.

[0088] On the other hand, as previously described, the display control circuit is further configured to, upon determining that a passenger is present on the passenger seat when no passenger is present, switch to normal mode to control the display operation of the non-driver's seat display area. In the case of a single timing controller (a first timing controller), the first timing controller may be configured to output a second timing signal corresponding to the non-driver's seat display area to the driver circuit (and simultaneously output a first timing signal corresponding to the driver's seat display area) based on a display control-related signal corresponding to the display data.

[0089] For example, the virtual operating systems (for example, one or two) that were disabled in low power consumption mode can be restored to output display control-related signals of corresponding display data to the first timing controller; or the virtual operating systems (for example, one or two) that provide low power consumption data to the first timing controller in low power consumption mode are controlled to provide display control-related signals of corresponding display data to the first timing controller; or when the central control display area and the co-pilot display area correspond to the same virtual operating system, the virtual operating system is controlled to output display control-related signals of corresponding display data to the first timing controller.

[0090] For example, with respect to the situation in FIG4A , when the normal display operation of the passenger display area is restored, the virtual operating system corresponding to the passenger display area resumes operation, thereby being able to output the display control-related signals of the display data corresponding to the passenger display area to the first timing controller TCON. Therefore, the first timing controller TCON can output the second timing signal T2 to the driving circuit (for example, the two driving chips IC3-IC4 corresponding to the passenger display area) (and simultaneously output the first timing signal T1 for the main driver display area to the driving circuit (for example, the two driving chips IC1-IC2 corresponding to the main driver display area)), and then the driving circuit can output the first driving signal and the second driving signal. In addition, when the vehicle-mounted display screen is an LCD display screen, the operating system of the display system can also control the backlight source corresponding to the passenger display area to turn on.

[0091] For another example, with respect to the situation in Figure 4B, the central control display area and the passenger display area correspond to the same virtual operating system. When the normal display operation of the passenger display area and / or the central control display area is restored, the virtual operating system can output display control-related signals of the display data corresponding to the passenger display area and / or the central control display area to the first timing controller. Therefore, the first timing controller TCON can output the second timing signal T2 to the driving circuit (for example, the driving chip corresponding to the passenger display area and the central control display area), and at the same time output the first timing signal T1 for the main driver display area to the driving circuit (for example, the driving chip corresponding to the main driver display area), and then the driving circuit can output the first driving signal and the second driving signal, so that all display areas can display normally.

[0092] For another example, in the case of Figure 4C , the central control display area and the passenger display area correspond to the same virtual operating system. Similar to Figure 4B , when normal display operation of the passenger display area is restored, the virtual operating system can output display control-related signals for the display data corresponding to the passenger display area to the first timing controller. Simultaneously, the virtual operating system can output display control-related signals for the display data corresponding to the central control display area to the first timing controller, and the operating system corresponding to the driver display area can output display control-related signals for the display data corresponding to the driver display area to the first timing controller. Therefore, the first timing controller can also provide the first and second timing signals to the driver circuit (e.g., the driver chips corresponding to the driver display area, central control display area, and passenger display area, respectively), so that the driver circuit can drive the corresponding display data to be normally displayed in each display area.

[0093] For another example, in the case of Figure 4D, the central control display area and the passenger display area correspond to different virtual operating systems. When the normal display operation of the passenger display area is restored, one of the two virtual operating systems that was previously stopped is restored, that is, all operating systems can output display control-related signals of corresponding display data to the first timing controller. Therefore, the first timing controller TCON can output a part T2-2 of the second timing signal corresponding to the passenger display area to the driving circuit (for example, a driving chip IC4 corresponding to the passenger display area), and at the same time output the first timing signal T1 for the main driver display area and the part T2-1 of the second timing signal for the central control display area to the driving circuit (for example, three driving chips IC1-IC3 corresponding to the main driver display area and the central control display area). Then, the driving circuit can output the first driving signal and the second driving signal, so that the corresponding display data is displayed normally in each display area.

[0094] In addition, for the situations of Figures 4A-4D, when the display area displays low-power data in low-power mode, when switching to normal mode, the virtual operating system that provides low-power data to the first timing controller in low-power mode can also be controlled to provide the first timing controller with display control-related signals of the corresponding display data, so that the driving circuit can normally output the first driving signal and the second driving signal, thereby normally displaying the corresponding display data in each display area.

[0095] On the other hand, when the display control circuit switches to controlling the display operation of the non-driver's display area in normal mode, in the case of two timing controllers (as shown in Figures 5A-5F), it can be configured to: turn on the switch between the first timing controller and the second timing controller, and each operating system also operates normally and outputs display control-related signals of normal display data, so that the second timing controller can output the second timing signal corresponding to the non-driver's display area to the driving circuit based on the display control-related signal of the corresponding display data, and the first timing controller can output the first timing signal corresponding to the driver's display area to the driving circuit based on the display control-related signal of the corresponding display data, so that the corresponding display data is displayed normally in each display area.

[0096] On the other hand, when the display control circuit switches to controlling the display operation of the non-driver's display area in normal mode, in the case of three timing controllers (as shown in Figures 6A-6B), it can be configured to: turn on the switches between the three timing controllers, and each operating system also operates normally and outputs normal display data, so that the timing controller corresponding to the non-driver's display area can output the second timing signal to the driving circuit based on the display-related control signal of the corresponding display data, and the timing controller corresponding to the driver's display area can output the first timing signal corresponding to the driver's display area to the driving circuit based on the display control-related signal of the corresponding display data, so that the corresponding display data is displayed normally in each display area.

[0097] It can be seen that based on the system structure diagram and system operation schematic diagram described above in combination with Figures 4A to 6B, when the on-chip system determines to control the non-driver display area in low-power mode based on the result of detecting whether there is someone on the passenger seat, it can realize the display operation control of various areas on the vehicle display screen by multiple operating systems by running a virtual machine. In this way, by combining software and hardware, when the passenger seat changes from being occupied to being occupied, the display corresponding to the passenger seat and / or the virtual operating system corresponding to the passenger seat can be started, and when the passenger seat changes from being occupied to being empty, the display corresponding to the passenger seat can be turned off and / or the virtual operating system corresponding to the passenger seat can be stopped. In this way, the display power consumption and the processor power consumption can be reduced, thereby improving the user experience.

[0098] According to another aspect of the present application, a display control method for a vehicle-mounted display screen is also provided.

[0099] Figure 7 shows a flow chart of a display control method for an in-vehicle display screen according to an embodiment of the present application. The in-vehicle display screen may be the in-vehicle display screen shown in Figure 1 and may include a driver's seat display area and a non-driver's seat display area, wherein the non-driver's seat display area includes at least a passenger seat display area. This display control method may be executed by the display system described above (e.g., a processor system, a display control circuit, and a driver circuit).

[0100] As shown in FIG. 7 , in step S710 , after the motor vehicle is started, it is determined whether there is a passenger on the front passenger seat.

[0101] Optionally, determining whether there is a passenger on the front passenger seat may include determining that there is no passenger on the front passenger seat of the motor vehicle only when a length of time after the motor vehicle is started that determines there is no passenger on the front passenger seat exceeds a preset threshold.

[0102] In step S720, when it is determined that there is no passenger on the co-pilot seat, the display operation of the non-driver display area is controlled in a low power consumption mode, wherein the display operations of the driver display area and the non-driver display area are separately driven by a first drive signal and a second drive signal.

[0103] Optionally, controlling the display operation of the non-driver's display area in a low power consumption mode may include: prohibiting the display operation of at least a portion of the non-driver's display area, or controlling at least a portion of the non-driver's display area to display low power consumption data.

[0104] For example, the low power consumption mode control of the display operation of the non-driver display area may be specifically implemented by combining multiple operating systems and one or more timing controllers as described above with reference to FIG. 4A-6B .

[0105] In addition, the method 700 may further include the following steps: when it is determined that there is someone on the front passenger seat when there is no passenger on the front passenger seat, switching to controlling the display operation of the non-main driver's seat display area in a normal mode.

[0106] In normal mode, each display area of ​​the vehicle display screen will normally display the corresponding display data (for example, instrument panel data, navigation data, entertainment audio and video data, etc.).

[0107] For more details of each step of method 700, please refer to the above contents with respect to FIG. 1 to FIG. 6B , and thus will not be repeated here.

[0108] According to yet another aspect of the present application, a motor vehicle is provided.

[0109] A motor vehicle may include a display system as described above to dynamically control the display on the vehicle's display screen based on whether there is someone in the passenger seat. This can reduce display power consumption and processor power consumption.

[0110] Alternatively, the processor system described above may be specifically a SOC or other processing system, for example, other processing systems may include a processor coupled to a computer-readable medium / memory via a bus. In some aspects, the computer-readable medium / memory is configured to store instructions (e.g., computer executable code) that, when executed by the processor, cause the processor to perform other operations of the processor system discussed herein. In some aspects, the computer-readable medium / memory stores various codes. In some aspects, the processor has circuitry configured to implement the code stored in the computer-readable medium / memory.
