Fig. 1 is a split display method of a vehicle-mounted display screen according to an embodiment of the present invention, as shown in fig. 1, the method includes the steps of:
step S101, acquiring a plurality of images to be displayed and screen parameters of a display screen;
in the embodiment of the present invention, content that a user needs to display on a vehicle-mounted display screen, that is, a plurality of images to be displayed, is obtained, for example: in another embodiment of the present invention, before the step of obtaining a plurality of images to be displayed and screen parameters of the display screen in step S101, as shown in fig. 2, the method further includes:
step S201, acquiring sub-screen parameters of a plurality of display screens;
step S202, combining a plurality of display screens according to the sub-screen parameters;
step S203, determining screen parameters of the combined display screen.
In the embodiment of the present invention, a plurality of screens may be disposed at the center console and the dashboard, and for this situation, sub-screen parameters of the plurality of screens may be obtained, where the sub-screen parameters include physical information such as size, position, and identifier of the screen, for example, there are 3 screens on the vehicle, the height of the screen is the same, and the screen display duty ratio is 2: 1: 1, the image can be divided according to the screen display proportion during image division, and the aims of displaying the same content by a plurality of display screens and enriching the video and audio functions are achieved. In addition, position information of a screen is required to be acquired, and the display position of a segmented image is determined. In another embodiment of the present invention, the method further comprises: determining the optimal resolution according to the sub-screen parameters; and adjusting the image to be displayed to the optimal resolution. When the screen parameters are acquired, the optimal resolution can be obtained at the same time, because the resolutions of the screens may be different, in order to optimize the viewing experience, all output pictures can be adjusted to the resolution meeting the requirement of the screen with the lowest resolution, and this step can also be executed before the step of controlling the display screen to display the corresponding image to be displayed on the sub-area, which may be determined according to the actual situation.
Step S102, determining the display positions of a plurality of images to be displayed according to control information input by a user;

Step S103, dividing the display area of the display screen according to the display position to obtain different sub-areas;
in the embodiment of the present invention, after the images to be displayed are acquired, the size of the synthesized image of all the images to be displayed is adjusted to be the same as the size of the screen, and the area of the display screen for displaying the image can be determined by the tangent point between the image frame and the frame, that is, by the display position, for example: and the right side of the image A is connected with the image B, the right side of the image B is connected with the image C, the overall size of the image is adjusted to be the same as the size of the screen, and the connecting point between the image A and the image B can be used as the tangent point of the display screen, so that the display area is determined.
And step S104, controlling the display screen to display the corresponding image to be displayed on the sub-area.
In the embodiment of the present invention, after the corresponding display area of the display image is obtained, the display area can be controlled to display the corresponding display image, specifically, a control manner triggered by a clock signal may be used, when a plurality of images to be displayed are obtained, each image has its own corresponding clock trigger signal, if the images need to be displayed on one display screen at the same time, it may be considered that a plurality of parallel clock signals are obtained, the parallel clock signals are superimposed on the same time axis to obtain a serial clock signal, and the serial clock signal is used to control the display screen to display the corresponding images to be displayed on the sub-area. In another embodiment of the present invention, before the step of controlling the display screen to display the corresponding image to be displayed on the sub-area in step S104, as shown in fig. 3, the method further includes:
step S301, determining the composite display parameters of the plurality of images to be displayed in the display screen according to the plurality of images to be displayed and the display positions;
step S302, determining a serial clock signal of a display screen when the display screen displays a plurality of images to be displayed according to the composite display parameters of the images to be displayed in the display screen;
in another embodiment of the present invention, in step S104, the step of controlling the display screen to display the corresponding image to be displayed on the sub-region includes: and controlling the display screen to display the corresponding images to be displayed in the display area in sequence according to the serial clock signals. At this time, the sizes of the multiple images to be displayed are adjusted to be the same as the size of the display screen, if the images are the same as the height of the display screen, a region to be displayed can be reserved on one side or two sides of the display screen, and a scheme can be determined according to control information of a user, which is not limited by the invention.
Step S303, determining a display area according to the serial clock signal and the screen parameter of the display screen.
In the embodiment of the present invention, the length of the display screen may be overlapped with the serial clock signal, and the size of the picture is adjusted to be consistent with that of the display screen, so that the boundary of the display area may be determined by the tangent point between the pictures on the serial clock signal, and the display area may be finally obtained, so as to achieve the purpose of displaying different contents on the composite screen.
