In order to better understand the technical scheme of the invention, the technical scheme of the invention is described in detail in the following with the accompanying drawings and specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
The display system 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 to the main display system for displaying. The main display system and the sub display system may be any two display systems, such as an instrument display system and a central control display system of a vehicle. The projection control method of the display system of the embodiment needs to be completed by the main display system and the auxiliary display system together.
As shown in fig. 1, the projection control method applied to the secondary display system side includes:
step S11, responding to the starting projection operation of a user, and establishing a data synchronous sharing channel between the main display system and the main display system;
s12, splitting the content to be projected of the application to be projected to obtain an element to be projected;
and S13, synchronously sharing the elements 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 a data synchronization sharing channel between the auxiliary display system and the auxiliary display system is established, receiving an element to be projected sent by the auxiliary display system through the data synchronization sharing channel;
s22, rendering and synthesizing the local display content and the element to be projected to obtain a data frame to be projected;
and step S23, displaying the content of the data frame to be projected.
In this embodiment, the projection start key may be disposed in the main display system or the sub-display system, and after the user presses the projection start key, a data synchronization sharing channel is established between the two systems for interaction, synchronization, and sharing of the projection data.
The auxiliary display system is provided with a rendering engine, the content to be projected of a certain application needing projection can be split to form elements, and the elements are synchronously shared 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 of the main display system (namely, the local display content) to form data frames, display the content on the display screen, realize the complete and uniform display of the image content on the display screen of the main display system, finally realize the projection of the content of the auxiliary display system to the main display system, and improve the diversity and richness of the display content of the main display system on the premise of not influencing the display content of the main display system.
In this embodiment, not only the content of the sub-display system can be projected onto the main display system, but also the touch control of the projected content of the sub-display system can be implemented on the main display system, and the touch control also needs to be implemented by the main display system and the sub-display system together. Specifically, at the end of the main display system, after step S23, the display system projection control method further includes:
responding to touch operation of a user in the projection area, and triggering a touch event;
and after the touch mapping between the touch event and the auxiliary display system is established, the touch event is sent to the auxiliary display system through the data synchronous sharing channel.
On the secondary display system side, after step S13, the display system projection control method further includes:
establishing a touch mapping between the touch screen and a projection area of a main display system to take over a touch event of the projection area;
and responding to the touch event after receiving the touch event sent by the main display system through the data synchronous sharing channel.
The main display system has a touch control function, before a touch event of the main display system is taken over by the auxiliary display system, the touch event can be triggered after a user clicks a display screen of the main display system, and the main display system responds to the touch event to complete the touch control of the main display system. In order to implement touch control on a projection area on a main display system, in this embodiment, a touch mapping is first established between the projection area of the main display system and an auxiliary display system, so that a touch event in the projection area is taken over by the auxiliary display system, a user triggers the touch event corresponding to projection content after clicking the projection area, the main display system does not respond to the touch event, but sends the touch event to the auxiliary display system through a data synchronization sharing channel, and a projected application in the auxiliary display system responds to the touch event corresponding to the projection content to implement touch control.
Generally, projection between the two display systems can be realized through coordinate transmission (acquisition, transmission and analysis), but the projection process is complex, the main display system can directly interact with the application body of the auxiliary display system, and the projection process is simple.
Certainly, after the projection between the main display system and the auxiliary display system is completed, the user needs to finish the projection, and the finishing of the projection also needs to be completed by the main display system and the auxiliary display system together. Specifically, at the side of the sub-display system, the projection control method of the display system further includes: in response to the end of the projection operation of the user, touch mapping is released; and closing the data synchronization sharing channel after the touch mapping is released. At the end of the main display system, the projection control method of the display system further comprises the following steps: in response to the end of the projection operation of the user, releasing the touch mapping; and closing the data synchronization sharing channel after the touch mapping is released.
The projection finishing key can be arranged on the main display system or the auxiliary display system, after a user presses the projection finishing key, touch mapping between a projection area of the main display system and the auxiliary display system is removed, 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 cannot be sent to the auxiliary display system, and therefore, in the projection finishing process, even if the user touches the projection area on the display screen of the main display system by mistake, the auxiliary display system cannot respond, and false touch can be avoided; and after the data synchronous sharing channel is closed, the elements split by the auxiliary display system are not sent to the main display system, the main display system only displays the content of the main display system, and the projection is finished.
In addition, the present embodiment may also end the projection by first closing the data synchronization sharing channel and then removing the touch mapping, and it can be understood that after closing the data synchronization sharing channel and before removing the touch mapping, the main display system only displays the content of itself, but the touch event in the projection area of the main display system is still taken over by the auxiliary display system, if the user clicks the content of itself in the projection area of the main display system, the touch event will be discarded, the main display system will not respond to the touch event, and the situation that neither the main display system nor the auxiliary display system responds when the user clicks the projection area will be caused, which greatly affects the user experience. In the embodiment, the touch mapping is preferably released first, and then the data synchronization sharing channel is closed to end the projection, so that the situation that the main display system and the auxiliary display system do not respond when a user clicks the projection area can be avoided, and the user experience is improved.
