Hereinafter, specific embodiments of the present disclosure will be described in detail with reference to exemplary embodiments and with reference to the accompanying drawings.
Fig. 1 is a block diagram illustrating an environment to which a method of controlling screen switching according to an embodiment of the present disclosure is applied. The method of controlling a screen according to an embodiment of the present disclosure may be applied to the system 100 as shown in fig. 1. System 100 includes a system processor 102 for running an operating system and a memory 104. The memory 104 is configured to store software code and the processor 102 is configured to read the memory 104 to run an operating system. For example, processor 102 runs an android system or other similar operating system. The system processor 102 has a plurality of display interfaces including a first display interface 106 and a second display interface 108. The first display interface 106 and the second display interface 108 are used to transmit image information, and are electrically connected to a first display screen 110 and a second display screen 112, respectively, so as to display an image on the display screens. The display screen may also be referred to as a display screen, a hardware display screen, a physical screen, and the like.
In the environment shown in FIG. 1, display control of multiple display screens 110, 112 is implemented by the system processor 102 running an operating system. In some embodiments, each display screen is provided with a touch screen, and the touch screens are arranged on the display screens and correspond to the display screens in a one-to-one mode. That is, on which display screen the display content is displayed, the touch operation on the display screen corresponds to the operation on the content of the display screen, thereby realizing the control of the user on the display content on the display screen. One of the plurality of display screens may be set as a main screen and the others may be set as sub screens. The system can appoint a certain entity screen to display the content of the main screen, and the operation function of the main screen is realized. The contents displayed in the main screen and the auxiliary screen are independently displayed, and the main screen and the auxiliary screen respectively run own application programs (APP) and cannot interfere with each other. The operation authority of the main screen is superior to that of the auxiliary screen, and the main screen can also freely control the display content of the auxiliary screen. For example, the main screen may control the APP of the sub-screen to turn off, or control the sound size of music playing on the sub-screen to pause, and so on. The secondary screen can only operate within the contents allocated by the system (or allocated by the primary screen), and cannot control the primary screen.
Herein, the main screen and the sub screen displaying different contents are referred to as an exclusive function, and the contents in which the plurality of screens all display the same are referred to as an exclusive function.
Fig. 2 is a flow diagram illustrating a method 200 of controlling screen switching according to an embodiment of the present disclosure. As shown in fig. 2, the method 200 includes the following steps S202 to S206.
In step S202, a virtual display area is set such that the virtual display area is associated with the home screen content. In some embodiments, a virtual display area is generated for virtually displaying home screen content. In the invention, the virtual display area is not displayed on the physical screen, namely, the display is not performed through the display interface, the display area is operated in the system, and the virtual display area can be displayed if the display interface is appointed.
In step S204, the home screen content is displayed on the first physical screen, and the sub-screen content corresponding to the home screen content is displayed on the second physical screen. In some embodiments, the display content of the virtual display area is displayed on the first physical screen through the co-display function, and the content of the secondary screen is displayed on the second physical screen through the non-display function. Therefore, the first entity screen is the main screen at the moment, the main screen content is displayed, the APP of the main screen is operated, and the touch operation on the first entity screen is the operation on the main screen content. When the content of the main screen is changed, the system can display the changed content of the main screen in the virtual display area, and the first entity screen with the simultaneous display function can also display the changed content of the main screen. The second entity screen is the auxiliary screen at the moment, the content of the auxiliary screen is displayed, the APP of the auxiliary screen is operated, and the touch operation on the second entity screen is the operation on the content of the auxiliary screen. Fig. 3 is a schematic diagram illustrating a screen display according to an embodiment of the present disclosure. At this time, the display diagram is shown in fig. 3, where the first entity screen displays the content of the main screen, and the second entity screen displays the content of the sub-screen. When a handover is to be performed, the process proceeds to step S206. In step S206, if a switching instruction is received, the main screen content is displayed on the second entity screen and the sub screen content is displayed on the first entity screen. In some embodiments, a switching instruction is obtained, the display content of the virtual display area is displayed on the second entity screen through the co-display function, and the content of the secondary screen is displayed on the first entity screen through the inter-display function. Thus, the first physical screen displays the contents of the secondary screen as the secondary screen and the second physical screen displays the contents of the primary screen as the primary screen. Fig. 4 is a schematic diagram illustrating a screen display according to an embodiment of the present disclosure. At this time, the display diagram is shown in fig. 4, where the first entity screen displays the content of the secondary screen, and the second entity screen displays the content of the primary screen. In this way, the switching of the home screen from the first physical screen to the second physical screen is completed.
In the embodiment, because the main screen content of the virtual display area is not changed, the system does not need to re-layout and render the main screen content, thereby reducing the switching time and achieving the effect of quickly switching the main screen and the auxiliary screen. Meanwhile, due to the fact that the content is always displayed in the switching process, the black screen condition can not occur, and the user experience effect is greatly improved.
Naturally, the switching operation may also be restored, that is, by acquiring the switching instruction again, the display content in the virtual display area may be displayed on the first entity screen through the simultaneous display function, and the content in the secondary screen may be displayed on the second entity screen through the separate display function. And then the situation that the first entity screen is the main screen and the second entity screen is the auxiliary screen is returned. In some embodiments, the operation of the secondary screen that requires the main screen is short, and generally, the secondary screen needs to be switched back after a certain operation is completed, a confirmation button (disappear after restoration) may be displayed after the main screen content is switched to the second entity screen, and after the user of the second entity screen completes the main screen function operation, the confirmation button may be clicked, so that the original main screen content may be quickly restored to the condition that the original main screen content is displayed on the first entity screen, and user experience may be provided.
As mentioned in the above embodiments, the entity screen of the present invention may be two or more, such as three. Multiple physical screens may specify switching home screen content to a physical screen. And if the designated entity screen is realized by a switching instruction, further, the switching instruction comprises the step of designating the entity screen to be switched in the first entity screen and the second entity screen, so that the main screen content is displayed on the designated entity screen in a mode of displaying the main screen content in the same way as the virtual display area. If the serial number of other entity screens can be displayed on the display screen (main screen display screen), the system can display the display main screen content of the virtual display area on the entity screen appointed to be switched through the simultaneous display function by selecting the entity screen to be switched. In some embodiments, the selected entity screen may be multiple, such that home screen content may be displayed simultaneously on multiple entity screens.
The operation of switching can be triggered by the system when a certain condition is met, such as triggering according to time or triggering according to a key, and the like. In some embodiments, the user clicks the switching interface to switch by displaying the switching interface on the main screen. That is, the home screen content of the present invention includes an interface associated with the switching instruction and the method of controlling screen switching further includes: receiving the switching instruction in response to the operation of the interface. It is emphasized here that, in general, the main-sub screen switching is generally operated by the main screen since the main screen has a higher authority. In the invention, the entity screen corresponding to the main screen is changed, the content of the main screen is displayed on which entity screen, and the interface of the switching instruction can be displayed on which entity screen, and then the user can operate, so that the system can acquire the switching instruction. The operation interface herein may be combined with the above-mentioned embodiments of multiple entity screens, that is, the main screen may display multiple entity screens to be switched, and after the user clicks the operation, the main screen may be switched to the clicked entity screen.
In an embodiment with a touch screen, the operation of the touch screen of the entity screen displaying the home screen content implements the operation of the home screen content, and the operation of acquiring the interface of the switching instruction includes: and acquiring touch operation of a touch screen of an entity screen displaying the content of the main screen. That is, when the home screen content is displayed on a certain physical screen and a switch is to be made to another physical screen, a switching operation is to be performed on the physical screen on which the home screen content is displayed. As shown in fig. 3, if the first entity screen displays the content of the home screen, the home screen can be switched by touching the first entity screen, and the home screen cannot be switched by touching the second entity screen. As shown in fig. 4, if the second entity screen displays the content of the home screen, the second entity screen may be touched to implement the home screen switching, and the first entity screen may not be touched to implement the home screen switching. The switching through the main screen is convenient for the management of the display of the main screen, and certainly, the switching of the main screen by the operation of the auxiliary screen can also be realized through specific setting, and the invention is not limited to the above.
The android system is preferred, the simultaneous display function is the simultaneous display function of the android system, and the different display function is the different display function of the android system. On other operating systems, the purpose of the invention can be realized by adopting the functions of the android simultaneous display and the differential display.
As the above embodiments have always emphasized that the main screen and the secondary screen have substantial differences, and the main screen has a significantly better privilege than the secondary screen in terms of basic privileges. In practice, the main screen can control the content display of the auxiliary screen, and the method further comprises the following steps: acquiring an auxiliary screen control operation performed on an entity screen displaying the main screen content in the first entity screen and the second entity screen; and changing the display content of the other entity screen of the first entity screen and the second entity screen which displays the content of the auxiliary screen according to the control operation of the auxiliary screen. The entity screen of main screen can control the display content of vice screen like this, if the APP that the main screen can control vice screen closes etc. the operation of the entity screen that vice screen corresponds can only respond in vice screen, realizes the different functional control of main and vice screen, satisfies different control needs.
The invention provides a multi-display-screen-based main and auxiliary screen switching control system which comprises a memory and a processor, wherein the processor is connected with more than two entity screens, a computer program is stored in the memory, and the computer program is executed by the processor to realize the steps of the method according to any one of the embodiments of the invention. According to the invention, through the virtual display area, as the main screen content of the virtual display area is not changed, the system does not need to re-arrange and render the main screen content, so that the switching time is reduced, the effect of rapidly switching the main screen and the auxiliary screen is achieved, meanwhile, because the content is always displayed in the switching process, the black screen condition is avoided, and the user experience effect is greatly improved.
In a specific product form, the multi-display-screen-based main and auxiliary screen switching control system is a multimedia classroom host system, a vehicle-mounted multi-screen system, a song-requesting multi-screen system or a cash register system. If in the vehicle-mounted multi-screen system, the main screen can realize the control of an air conditioner in a vehicle, when a rear row user needs to control the air conditioner, the main screen of the main driving can switch the content of the main screen to the rear row display and the air conditioner control, and then the main screen is switched back, so that the partial operation of the rear row in a period of time is facilitated, the integral control is still the main driving in the front row, and the user experience is improved.
