Detailed Description
The embodiment of the invention solves the technical problem of projecting the content of the auxiliary display system to the main display system by providing the display system, the projection control method thereof and the main and auxiliary display systems.
In order to better understand the technical scheme of the present invention, the following detailed description will refer to the accompanying drawings and specific embodiments.
First, the term "and/or" appearing herein is merely an association relationship describing associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
The display system of the embodiment comprises a main display system and a secondary display system, and the display system projection control method is used for projecting the content to be projected of the application to be projected in the secondary display system into the main display system for display. The primary display system and the secondary display system may be any two display systems, such as an instrument display system and a center control display system of a vehicle. The projection control method of the display system in this embodiment needs to be completed by the main display system and the auxiliary display system.
As shown in fig. 1, the projection control method applied to the secondary display system end includes:
step S11, a data synchronization sharing channel between the main display system and the user is established in response to the starting projection operation of the user;
step S12, splitting the content to be projected of the application to be projected to obtain elements to be projected;
step S13, synchronously sharing the element to be projected to the main display system through the data synchronous sharing channel.
As shown in fig. 1, the projection control method applied to the main display system includes:
step S21, after establishing a data synchronization sharing channel with the auxiliary display system, receiving elements to be projected sent by the auxiliary display system through the data synchronization sharing channel;
step S22, rendering and synthesizing the local display content and the element to be projected to obtain a data frame to be projected;
step S23, content display is carried out on the data frame to be projected.
In this embodiment, the projection start key may be disposed in the primary display system or may be disposed in the secondary display system, and after the user presses the projection start key, a data synchronization shared channel is established between the two systems for interaction, synchronization and sharing of projection data.
The auxiliary display system is provided with a rendering engine, which can split the content to be projected of a certain application to be projected to form elements, and synchronously share the elements to the main display system through a data synchronous sharing channel. The main display system is also provided with a rendering engine, which can render and synthesize the received elements and the display content (namely the local display content) of the main display system to form a data frame, and display the content on the display screen, so that the complete and unified display of the image content on the display screen of the main display system is realized, and finally, the projection of the content of the auxiliary display system to the main display system is realized, and the diversity and the richness of the display content of the main display system are improved on the premise that the display content of the main display system is not influenced.
In this embodiment, besides the projection of the content of the secondary display system onto the primary display system, touch control of the projected content of the secondary display system may be implemented on the primary display system, where the touch control is also required to be completed by both the primary display system and the secondary display system. Specifically, at the main display system end, after step S23, the display system projection control method further includes:
triggering a touch event in response to a touch operation of a user in a projection area;
after the touch mapping between the touch sensor and the auxiliary display system is established, the touch event is sent to the auxiliary display system through the data synchronization sharing channel.
At the secondary display system end, after step S13, the display system projection control method further includes:
establishing a touch mapping between the touch screen and a projection area of the main display system so as to take over touch events of the projection area;
and after receiving the touch event sent by the main display system through the data synchronous sharing channel, responding to the touch event.
The main display system has a touch control function, and after a user clicks a display screen of the main display system before a touch event of the main display system is taken over by the auxiliary display system, the touch event is triggered, and the main display system responds to the touch event to complete touch control of the main display system. In order to realize touch control on a projection area on a main display system, in the embodiment, touch mapping is firstly established between the projection area of the main display system and a secondary display system, so that a touch event of the projection area can be taken over by the secondary display system, after a user clicks the projection area, a touch event corresponding to projection content is triggered, the main display system does not respond to the touch event, but sends the touch event to the secondary display system through a data synchronous sharing channel, and a projected application in the secondary display system responds to the touch event corresponding to the projection content to realize touch control.
In general, the projection between the two display systems can be realized through coordinate transmission (acquisition, transmission and analysis), but the projection process is complex, and the main display system can directly interact with the application body of the auxiliary display system in the embodiment, so that the projection process is simple.
Of course, after the projection between the main display system and the auxiliary display system is completed, the user also needs to end the projection, and the projection is completed by the main display system and the auxiliary display system together. Specifically, at the secondary display system end, the display system projection control method further comprises the following steps: releasing the touch mapping in response to the user's end projection operation; after the touch mapping is released, the data synchronization sharing channel is closed. At the main display system end, the display system projection control method further comprises the following steps: releasing the touch mapping in response to the user's end projection operation; after the touch mapping is released, the data synchronization sharing channel is closed.
The end projection key can be arranged on the main display system or the auxiliary display system, after a user presses the end projection key, touch mapping between a projection area of the main display system and the auxiliary display system is released, the auxiliary display system returns a touch event of the projection area to the main display system, the touch event triggered by the projection area on a display screen of the main display system is discarded and not sent to the auxiliary display system, and therefore, in the process of ending projection, even if the user mistakenly touches the projection area on the display screen of the main display system, the auxiliary display system does not respond, and mistaken touch can be avoided; after the data synchronous sharing channel is closed, the split elements of the auxiliary display system are not sent to the main display system, and the main display system only displays the self content and the projection is finished.
In addition, the embodiment can also end the projection by closing the data synchronous sharing channel and then releasing the touch mapping, and it can be understood that after closing the data synchronous sharing channel and before releasing the touch mapping, the main display system only displays the self content, but the touch event of the projection area of the main display system is still taken over by the auxiliary display system, if the user clicks the self content in the projection area of the main display system, the touch event can be discarded, the main display system does not respond to the touch event, and the situation that the main display system and the auxiliary display system do not respond when the user clicks the projection area can be caused, so that the user experience is greatly influenced. In the embodiment, the touch mapping is preferably released first, and then the data synchronization sharing channel is closed to finish projection, so that the situation that the main display system and the auxiliary display system are not responsive when a user clicks a projection area can be avoided, and user experience is improved.
