In this embodiment, when the display screen is in the first state and the data to be displayed includes one path of data, the data to be displayed is decomposed into first sub-data and second sub-data, the first sub-data is sent to the first display control module, and the second sub-data is sent to the second display control module. The first sub data and the second sub data are obtained by decomposing data to be displayed by the system chip.
For example, if the user wants to watch the video in full screen through the vehicle-mounted terminal, the display screen is in the first state of full screen display at this time, and the video data may be the video downloaded from the cloud. Because the screen display system of the embodiment is provided with the first display control module and the second display control module, video data is transmitted to the display screen end through two paths, the video data can be decomposed into two parts of first sub-data and second sub-data through the system chip, wherein the first sub-data is respectively sent to the first display control module, so that a picture corresponding to the first sub-data is displayed through the first display area, the second sub-data is sent to the second display control module, and a picture corresponding to the second sub-data is displayed through the second display area. For example, an object a is displayed in the current screen, the object a includes an upper half and a lower half, and the upper half of the object a may be displayed through a first display area and the lower half of the object a may be displayed through a second display area, thereby displaying the complete object a.
In this embodiment, when the display screen is in the second state and the data to be displayed includes one path of data, the data to be displayed is sent to the first display control module or the second display control module.
For example, in one scenario, the vehicle is in a parking state, the co-driver is unmanned, the driver wants to watch the video through the vehicle-mounted terminal, the driver can only control the first display area of the display screen to work, the second display area is controlled to stop the screen, and the system chip can send the video to the first display area for display through the first display control module after acquiring the video downloaded from the cloud.
In this embodiment, when the display screen is in the second state and the data to be displayed includes the first data and the second data, the first data is sent to the first display control module, and the second data is sent to the second display control module, where the first data and the second data have different data transmission paths.
For example, in one scenario, the driver needs to see the vehicle's instrumentation and centering information while the vehicle is traveling, while the co-driver location person wants to see the video. The system chip can acquire the instrument and central control information of the vehicle from the vehicle general control, video data is downloaded from the cloud, at the moment, the first data are the instrument and central control information of the vehicle, the second data are the video data downloaded from the cloud, the instrument and central control information are sent to the first display area to be displayed through the first display control module, and the video data are sent to the second display area through the second display module.
According to the embodiment, the display screen is divided into the first display area and the second display area, the first display area and the second display area are respectively controlled through the first display control module and the second display control module, so that full-screen display and partition display of the display screen can be achieved, data to be displayed are decomposed into first sub-data and second sub-data during full-screen display, the first sub-data and the second sub-data are respectively sent to the first display area and the second display area for display, the first data and the second data are respectively sent to the first display area and the second display area for display during partition display, full-screen display and partition display of the vehicle-mounted terminal can be met, and power consumption of equipment can be controlled through controlling the first display control module and the second display control module, so that balance of power consumption and display effect is achieved.
