In the embodiment of the present invention, the running state of the newly started application program interface acquired by the acquiring module 121 is the running state, and the running state of the running application program interface is the ready-to-pause state. If the running state of the running application program interface is not modified at this time, the running application program interface is suspended, and only the newly started application program interface corresponds to the screen of the screen ID number. Therefore, the embodiment of the invention can change the running state of the running application program interface being displayed from the ready-to-pause state to the active state, so that the running application program interface being displayed can be displayed on the screen corresponding to the screen ID number.
The working process of the multi-screen display system of the embodiment of the invention is based on the frame work layer of the vehicle-mounted entertainment system. When the vehicle entertainment system is started, the detection driver of the kernel layer detects each device connected to the vehicle entertainment system, and allocates driving and physical ports for each device. Further, the multi-screen display system of the present embodiment is invoked after entering the frame layer.
In one embodiment of the invention, the plurality of screens may include touchable screens and non-touchable screens, wherein the touchable screens include a main display screen (CSD) and an air conditioning display screen (CSDM) that are responsive to a user's touch screen operation. Non-touch screens include a meter Display (DIM) and a heads-up display (HUD), which cannot respond to a user's touch screen operation.
Referring to fig. 2, the main display 21, the air conditioner display 22, and the meter display 23 are connected to the vehicle-mounted entertainment host 20 (IHU) through a physical LVDS (Low-Voltage Differential Signaling, low voltage differential signaling) interface (not shown), and the vehicle-mounted entertainment host 20 is responsible for outputting data transmission streams to the three screens. The instrument display 23 and the head-up display 24 share the same low voltage differential signaling LVDS data transmission stream, so the screen IDs of the instrument display 23 and the head-up display 24 are the same, the instrument display 23 is directly connected with the vehicle-mounted entertainment host 20, the head-up display 24 is indirectly connected with the vehicle-mounted entertainment host 20 via the instrument display 23, and the instrument display 23 transmits the data transmission stream to the head-up display 24.
In this embodiment, for example, the screen manager 110 assigns a screen ID of 0 to the main display screen 21, a screen ID of 1 to the meter display screen 23 and the head-up display 24, and a screen ID of 2 to the air conditioner display screen 22.
In connection with fig. 1 and 2, in order to more clearly embody the present invention, an embodiment of the present invention will now be described with a specific example.
Assume that a running music application interface is being displayed on the meter display 23. After the navigation application interface is newly started on the main display screen 21, the acquisition module 121 of the application manager 120 acquires that the screen ID number corresponding to the navigation application interface is 0 and the running state is the active state, and acquires that the screen ID number corresponding to the music application interface is 1 and the running state is the ready-to-pause state.
Furthermore, the detection module 122 of the application manager 120 determines that the screen ID number 0 corresponding to the navigation application interface is different from the screen ID number 1 corresponding to the music application interface, and changes the running state of the music application interface from the ready-to-pause state to the active state, while the active state of the navigation application interface remains unchanged, at this time, the music application interface can be continuously displayed on the meter display screen 23, and the newly started navigation application interface can also be simultaneously displayed on the main display screen 21.
In the embodiment of the present invention, since the meter display 23 is a non-touch screen, it is not possible to directly respond to the touch screen operation of the user. Accordingly, the music application being displayed on the meter display screen 23 is executed by the user performing a start operation of the music application on the main display screen 21, and setting the display screen as the meter display screen 23.
In this embodiment, the music information presented on the music application interface may include one or more of song title, singer information, duration, progress bar, lyrics, etc. The navigation signal displayed on the navigation application interface may include current road condition information, vehicle position information, and the like, which is not limited in this embodiment.
Referring to fig. 3, in an embodiment of the present invention, the multi-screen display system may further include a split-screen setter 130, where the split-screen setter 130 is connected to the detection module 122, and after the detection module 122 determines that the screen ID number of the screen where the newly started application program interface is located is the same as the screen ID number of the screen where the running application program interface is being displayed, the screen window mode corresponding to the screen with the same ID number is set to an adjustable free mode. Thus, the display size of the screen window corresponding to the screen with the same ID number can be set according to the size of the actual screen.
Further, after setting the screen window mode corresponding to the screen with the same ID number as the adjustable free mode, the split-screen setter 130 may also adjust the size information of the newly started application program interface according to the window display size of the screen where the newly started application program interface is located, and adjust the size information of the currently displayed running application program interface according to the window display size of the screen where the currently displayed running application program interface is located. And combining the adjusted size information of the application program interface, and providing the combined size information and other related information of the application program interface for a screen directly connected with the vehicle-mounted entertainment host. And finally, the screen directly connected with the vehicle-mounted entertainment host computer reserves and displays the related information of the self-adaptive application program interface, and sends the related information of the other application program interfaces to the screen indirectly connected with the vehicle-mounted entertainment host computer.
In an embodiment of the present invention, in the process of displaying different application program interfaces on different screens, if the ID numbers of the screens where the different application program interfaces are located are the same, it is further required to analyze whether the task ID numbers of the application program interfaces are the same. To avoid the same application program interface being displayed on different screens. Specifically, the related information of the application program interface further includes a task ID number of the application program interface, when the detection module 122 determines that the screen ID number of the screen where the newly started application program interface is located is the same as the screen ID number of the screen where the running application program interface is being displayed, it further determines whether the task ID number corresponding to the newly started application program interface is the same as the task ID number of the running application program interface being displayed, and when the task ID numbers are different, the running state of the running application program interface being displayed can be changed from the ready-to-pause state to the active state, so that the newly started application program interface and the running application program interface being displayed are respectively displayed on the corresponding screens.
In connection with fig. 2 and 3, in order to more clearly embody the foregoing, an embodiment of the present invention will now be described with a specific example.
In this embodiment, the meter display 23 is directly connected to the vehicle entertainment host 20, the head-up display 24 is indirectly connected to the vehicle entertainment host 20 via the meter display 23, and the meter display 23 and the head-up display 24 share the same low voltage differential signaling LVDS data transmission stream.
Assume that a running music application interface is being displayed on the meter display 23. After the navigation application interface is newly started on the head-up display 24, the acquisition module 121 acquires that the screen ID number corresponding to the navigation application interface is 1 and the running state is the active state, and acquires that the screen ID number corresponding to the music application interface is 1 and the running state is the ready-to-pause state. Further, after the detection module 122 determines that the screen ID number 1 corresponding to the navigation application interface is the same as the screen ID number 1 corresponding to the music application interface, the split-screen setter 130 performs the split-screen operation.
In this embodiment, assuming that the screen window display size of the meter display screen 23 is 1920×720 and the screen window display size of the head-up display 24 is 640×360, the split-screen setter 130 sets the size information of the music application interface to 1920×720 and the size information of the navigation application interface to 640×360. And then combining the size information of the music application program interface and the navigation application program interface, wherein the size information of different application program interfaces is combined, namely the different application program interfaces are spliced, and the combined size information corresponds to the combined application program interface. This embodiment defines the location of two different sized application program interfaces in the combined application program interface, for example, the music application program interface in the combined application program interface is in the upper position, the navigation application program interface is in the lower left position, and in order to ensure that the combined application program interface is rectangular, the interface supplementation is also performed in the lower right position in the combined application program interface.
The size information of the combined application interface finally provided to the meter display 23 may be 1920 x 1080. After receiving 1920×1080 interface size information, the meter display 23 splits the size information of the combined application program interface, retains the music application program interface according to the display size 1920×720 of its own screen window and the position of the music application program interface, and provides 640×360 interface size information of the navigation application program interface to the head-up display 24.
Further, when the detection module 122 determines that the task ID number corresponding to the music application interface and the task ID number of the navigation application interface are different, the running state of the music application interface is changed from the ready-to-pause state to the active state, so that the music application interface is continuously displayed on the meter display screen 23, the newly started navigation application interface is displayed on the head-up display 24, and the display of the two application interfaces is not affected.
In the embodiment of the present invention, since the meter display screen 23 and the head-up display 24 are both non-touch screens, it is impossible to directly respond to the touch screen operation of the user. Thus, the running music application and the newly started navigation application on the head-up display 24 are displayed on the meter display screen 23 by the user performing the start operation of the music application and the navigation application on the main display screen 21, respectively, and setting the corresponding display screens.
In an embodiment of the present invention, since the operation of multiple applications can be performed on the main display 21, multiple applications may be started through the main display 21, so as to avoid that the screen where the newly started application interface and the running application interface are not the main display 21, after determining that the screen ID number of the screen where the newly started application interface is the same as the screen ID number of the screen where the running application interface is being displayed, it is further required to analyze whether the same screen ID number is the ID number of the main display 21, and when the same screen ID number is not the ID number of the main display 21, the split-screen setter 130 will further perform the subsequent split-screen operation.
In an embodiment of the present invention, when the screen ID number of the screen where the newly started application program interface is located is different from the screen ID number of the screen where the running application program interface is being displayed, the vehicle-mounted entertainment host 20 creates stacks for the two application programs respectively, and starts tasks in the stacks of the two application program interfaces respectively for executing the newly started application program and the running application program being displayed, and when the newly started application program interface and the running application program interface being displayed on the corresponding screens respectively, the running states of the two application program interfaces in the stacks are active states. In this embodiment, the relevant information of the application program interfaces also includes stack information.
In another embodiment of the present invention, when the screen ID number of the screen where the newly started application program interface is located is the same as the screen ID number of the screen where the running application program interface is being displayed, although the same screen shares the same data transmission stream, in order to ensure that two application programs independently run in the vehicle-mounted entertainment host 20, the split screen setter 130 may be used to notify the vehicle-mounted entertainment host 20 to create two independent stacks for the newly started application program and the running application program, and create tasks in each stack respectively, so that the newly started application program and the running application program are executed in different tasks respectively, and further the running application program is not affected when the running failure of one application program occurs.
According to the scheme, whether the multiple screens respectively use multiple LVDS data streams or the multiple screens share the same LVDS data stream, the multiple screens can simultaneously display different application program interfaces, and therefore good user driving experience can be achieved.
Based on the same inventive concept, the embodiment of the present invention further provides a multi-screen display method, and fig. 4 shows a schematic flow chart of the multi-screen display method according to one embodiment of the present invention, and referring to fig. 4, the multi-screen display method includes steps S410 to S414.

In this step, the relevant information of the application program interface includes a screen ID number of a screen on which the application program interface is located and an operation state of the application program interface. The acquired running state of the newly started application program interface is an active state, and the running state of the running application program interface is a ready-to-pause state;
step S412, judging whether the screen ID number of the screen where the newly started application program interface is located is the same as the screen ID number of the screen where the running application program interface is being displayed; if not, go to step S414, if yes, end.
In step S414, the newly started application program interface and the running application program interface being displayed are displayed on the screen corresponding to the screen ID number, respectively.
In an embodiment of the present invention, before executing step S410 to obtain relevant information of each of the newly started application program interface and the running application program interface being displayed, a screen ID number may be allocated to each of the multiple screens connected to the vehicle-mounted entertainment host and stored. Wherein the screen ID number assigned to the screen may be stored in a memory of the in-vehicle entertainment system.
Of course, other relevant information of the application program of the embodiment of the present invention may also be stored in the memory of the vehicle entertainment system. Subsequently, when the related information of the newly started application program interface and the running application program interface is acquired, the information can be directly acquired from the memory.
In an embodiment of the present invention, if it is determined in step S412 that the screen ID number of the screen where the newly started application interface is located is the same as the screen ID number of the screen where the running application interface is being displayed, the screen window mode corresponding to the screen with the same ID number may be set as the adjustable free mode. Further, the corresponding screen window display size is set according to the screen size of which the screen ID number is the same.
And adjusting the size information of the newly started application program interface according to the window display size of the screen where the newly started application program interface is located, and adjusting the size information of the running application program interface according to the window display size of the screen where the running application program interface is being displayed. And combining the size information of the adjusted application program interface, sending the combined size information and other related information of the application program interface to a screen directly connected with the vehicle-mounted entertainment host, reserving and displaying the related information of the application program interface adapted to the screen by the screen directly connected with the vehicle-mounted entertainment host, and sending the related information of the other application program interfaces to the screen indirectly connected with the vehicle-mounted entertainment host.
