The display data stream also comprises the screen size of the mobile terminal, and can also be represented by the resolution, and the most appropriate screen projection display area and the vehicle display area dividing mode can be obtained after the vehicle screen data and the display data stream are compared.
And step S30, displaying the display content of the car machine in the car machine display area, and displaying the display data stream in the screen projection display area.
And the display data stream is encoded before the mobile terminal sends the display data stream, and after the display data stream is received by the vehicle-mounted device, the content corresponding to the display data stream is displayed in a screen-projection display area after the display data stream is decoded. The display method of the screen-casting display area can be that an interface displayed by a screen of the mobile terminal is directly cast to a screen of the vehicle, and when application software corresponding to the mobile terminal exists in the vehicle, the interface can be directly displayed in a self-contained application mode of the vehicle, for example, the vehicle receives a display data stream including the WeChat data sent by the mobile terminal, and at the moment, the WeChat software in a vehicle system can be directly called to display the WeChat data.
The number of the projection screen display areas is one or more.
Since the display data stream includes a plurality of data streams, it is sometimes necessary to display a plurality of contents on the screen of the car machine, for example, to play a video while displaying a WeChat.
According to the multi-source content display method and the multi-source content display device, the multi-source content can be displayed at the same time by dividing the display area of the vehicle machine and the screen projection display area, and the use convenience of a user is improved.

and step S24, setting a screen projection display area and a vehicle display area according to the size of the screen projection display area and the size of the vehicle display area.
The size of the screen-throwing display area is calculated through the screen data of the vehicle machine and the screen data of the mobile terminal, so that the size of the screen-throwing display area can meet the display requirement as much as possible on the basis of complete display, after the size of the screen-throwing display area is obtained, the size of the screen-throwing display area is subtracted from the size of the vehicle machine screen to obtain the size of the vehicle machine display area, and then the respective display areas are divided on the vehicle machine screen according to the size of the screen-throwing display area and the size of the vehicle machine display area. It should be noted that, when dividing the screen-projecting display area and the in-vehicle display area, it is necessary to ensure that the screen-projecting display area and the in-vehicle display area are both rectangular display areas, and in this embodiment, the screen-projecting display area and the in-vehicle display area are set in a left-right split screen mode or a top-bottom split screen mode.
In this embodiment, the size of the screen projection display area is set through the vehicle machine screen data and the mobile terminal screen data, and the size of the vehicle machine display area is calculated according to the vehicle machine screen data and the screen projection display area, so that the screen projection display area can ensure that the mobile terminal interface is displayed completely.
Further, in a fourth embodiment of the car-mounted device screen display method according to the present invention based on the fourth embodiment of the present invention, the step S22 includes the steps of:
step S221, when the display data stream type is a cross-screen display data stream, calculating a ratio of a vertical resolution in the vehicle machine screen data to a horizontal resolution in the mobile terminal screen data to obtain a first cross-screen zoom coefficient, and calculating a ratio of a horizontal resolution in the vehicle machine screen data to a vertical resolution in the mobile terminal screen data to obtain a second cross-screen zoom coefficient;

step S225, setting the minimum value of the first vertical screen zooming coefficient and the second vertical screen zooming coefficient as a second zooming coefficient;
step S226, respectively multiplying the vertical resolution and the horizontal resolution of the screen of the mobile terminal by the second scaling factor to obtain the height and the width of the display area of the projection screen.
And the minimum of the calculated scaling coefficients is used as the final scaling coefficient, so that the longer side of the mobile terminal can be completely displayed in the screen projection display area. Because of the difference of the application software, there are different display modes, for example, when using the WeChat, generally, the display mode is vertical screen mode, and when using the video application, generally, the display mode is horizontal screen mode, therefore, it is necessary to consider the display mode of the display data stream on the mobile terminal when dividing the screen projection display area, so as to be able to adaptively display on the car machine screen, because the common state of the mobile terminal is the vertical screen using state, the vertical resolution and the horizontal resolution in the screen data in the mobile terminal are based on the vertical screen, when the display data stream type is horizontal screen display data stream, it is necessary to interchange the vertical resolution and the horizontal resolution, therefore, the vertical resolution of the mobile terminal screen is multiplied by the first scaling factor to obtain the width of the screen projection display area, the horizontal resolution of the mobile terminal screen is multiplied by the first scaling factor, and obtaining the height of the projection screen display area. And when the display data type is a vertical screen display data stream, a projection screen display area is obtained directly through equal scaling.
In the embodiment, the minimum scaling coefficient obtained by calculation is used as the final scaling coefficient, so that the screen projection display area is maximized on the basis of ensuring the complete display of the display area of the mobile terminal, and the screen projection display area is set according to different display contents by distinguishing the horizontal screen display data stream and the horizontal display data stream, thereby ensuring the screen projection accuracy.

and step S40, receiving a full screen projection playing instruction, and displaying the display data stream in a full screen mode.
When some applications perform screen projection, full-screen display is needed to optimize the screen projection effect, for example, when the display data stream is a video stream, the video is played in full-screen mode to give the best impression to the user. Therefore, after the user sends a full-screen-casting playing instruction, the in-vehicle screen displays the display data stream in full screen, and it should be noted that whether the full-screen display data stream or the in-vehicle display content can be selected by the user.
In the embodiment, when a full-screen-projection playing instruction is received, the display data stream is displayed in a full screen, so that the use requirement of a user is met.
Further, in a sixth embodiment of the car-mounted device screen display method according to the present invention based on the first embodiment of the present invention, the method further includes the steps of:
step S50, receiving a touch instruction triggered by the screen projection display area, and sending the touch instruction to the mobile terminal, so that the mobile terminal executes an operation corresponding to the touch instruction.
