And after the kernel is started, loading the Shell and the user application program. The application program is compiled into machine code after being started, and a process is formed.

A schematic diagram of the software configuration in the display device 200 according to some embodiments is illustrated in fig. 4. Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.

In some embodiments, at least one application program runs in the application program layer, and the application programs can be Window (Window) programs carried by an operating system, system setting programs, clock programs, camera applications and the like; or may be an application developed by a third party developer such as a hi program, a karaoke program, a magic mirror program, or the like. In specific implementation, the application packages in the application layer are not limited to the above examples, and may actually include other application packages, which is not limited in this embodiment of the present application.

The framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resource in the system and obtain the service of the system in execution through the API interface

As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is configured to manage all window processes, such as obtaining a display size, determining whether a status bar is available, locking a screen, intercepting a screen, controlling a display change (e.g., zooming out, dithering, distorting, etc.) and the like.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, the android operating system runs the C/C + + library included in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (such as fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and so on.

In some embodiments, taking the magic mirror application (photographing application) as an example, when the remote control receiving device receives a remote control input operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into an original input event (including information such as a value of the input operation, a timestamp of the input operation, etc.). The raw input events are stored at the kernel layer. The application program framework layer obtains an original input event from the kernel layer, identifies a control corresponding to the input event according to the current position of the focus and uses the input operation as a confirmation operation, the control corresponding to the confirmation operation is a control of a magic mirror application icon, the magic mirror application calls an interface of the application framework layer to start the magic mirror application, and then the kernel layer is called to start a camera driver, so that a static image or a video is captured through the camera.

In some embodiments, for a display device with a touch function, taking a split screen operation as an example, the display device receives an input operation (such as a split screen operation) that a user acts on a display screen, and the kernel layer may generate a corresponding input event according to the input operation and report the event to the application framework layer. The window mode (such as multi-window mode) corresponding to the input operation, the position and size of the window and the like are set by an activity manager of the application framework layer. And the window management of the application program framework layer draws a window according to the setting of the activity manager, then sends the drawn window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface in different display areas of the display screen.

An icon control interface display diagram of an application in display device 200 according to some embodiments is illustrated in fig. 5. In some embodiments, as shown in fig. 5, the application layer containing at least one application may display a corresponding icon control in the display, such as: the system comprises a live television application icon control, a video on demand application icon control, a media center application icon control, an application center icon control, a game application icon control and the like.

In some embodiments, the live television application may provide live television via different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

In some embodiments, a video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

In some embodiments, an application center may provide storage for various applications. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

In some embodiments, when a browser (e.g., Cobalt) in a display device is used to display a certain web application, the current browser implementation is generally divided into a core layer and a docking layer; the docking layer is used for docking with specific hardware of the bottom layer (display device) to realize hardware-related functions, such as window drawing and media playing functions. The core layer is connected with the docking layer and is used for realizing communication between the core layer and the underlying platform (display device).

The docking layer is configured with a window interface layer (window API) for calling the underlying platform to create a window, and window creation involves many attributes such as width and height, cache size, layer number (layer), and the like. The layer number (layer) is to finally fuse the contents rendered in different layers together to achieve the purpose of realizing an interface with rich contents.

When the graphics composition is implemented, taking video playing in a Display device as an example, when the video playing is implemented, the graphics composition needs to be implemented by using a video layer and an OSD (On Screen Display) layer, where the video layer is used for implementing the video playing, and the OSD layer is used for displaying a playing picture. For the purpose of graphical display, there is a priority distinction between different layers, with a high priority layer overlaying a low priority layer. For example, the video layer has a lower priority than the OSD layer, i.e., the OSD layer is displayed above the video layer during video playback.

A display diagram of OSD layer priorities and applications according to some embodiments is illustrated in fig. 6. Referring to fig. 6, layers such as Layer0, Layer1, Layer2, etc. are typically included in the OSD Layer, and the priorities of the three layers are Layer 2< Layer 0< Layer1, and the direction of the arrow is the direction of the user's line of sight, i.e., Layer1 is located at the uppermost Layer, and Layer2 is located at the lowermost Layer.

In some embodiments, when a user interface Of an application is presented using a display device, the UI Layer typically used to present the user interface is located at the top Layer (Layer1) and the application is located at the middle Layer (Layer0), where the application may be YouTube, Amazon (a video website), EPOS (Electronic Point Of Sale), etc.

The applications of YouTube, Amazon, EPOS (the three are located at the Layer0 level) and UI (the Layer1 level) are all single-page Web applications (SPA) based on browser implementation, that is, Web applications. Because the related implementation of the Window interface layer (Window API) interface in the docking layer of the Cobalt browser only has a Window with one attribute setting (for example, a hierarchical setting), that is, after the current Cobalt browser is started each time, the created windows are all of the same attribute, that is, each application is displayed at a fixed level after being started. However, as the kinds of applications supported by the display device increase, there may be new applications that are required to be presented in the Layer1 Layer.

Fig. 7 is a schematic diagram illustrating display of OSD layer priorities and new applications according to some embodiments; a display diagram of the Layer1 Layer is illustrated in fig. 8, according to some embodiments. Referring to fig. 7 and 8, the new applications that need to be presented in the Layer1 Layer may be Google Assistant and Amazon APL (Alexa Presentation Language), when the applications of Google Assistant, Amazon APL, and UI Layer are in the same Layer1 Layer.

Although the three are shown in the same Layer (Layer1), there is a fixed order between the three, for example, Google assignment is at the top, APL is the second, UI is at the bottom. As can be seen, such a setting will cause the function that needs to be displayed at the forefront in the UI to be blocked, that is, when a new web application is started, the newly started web application blocks the function that needs to be displayed at the topmost layer in the previously started web application (the application already displayed in the UI layer), where the function that needs to be displayed at the topmost layer in the web application includes a volume bar, a device or a status prompt icon, and the like.

Therefore, to avoid occlusion, the function is displayed on the top Layer of the OSD (i.e., the top Layer of Layer 1). In some embodiments, the function that needs to be displayed on the top layer of the OSD is used as a system function, which is a sub-module in the UI layer, such as a system menu, a volume bar, a device or status prompt icon, etc.

Therefore, due to the characteristic that the existing UI layer is displayed in a single image layer, all functions related to the UI are displayed in the same layer. However, when some functions are required to be displayed on the top layer of the OSD and other functions are still displayed on the bottom layer of the top layer of the OSD, the single-layer display method cannot be implemented, so that different functions of the web application displayed on the UI layer cannot be displayed simultaneously.

Therefore, in order to enable different functions of a web application displayed in a UI layer to be displayed simultaneously, embodiments of the present invention provide a mechanism for supporting multi-layer display of a web application, where a UI layer is split into two different layers, namely, a UI core layer and a UI system layer, and a communication mechanism, a data sharing mechanism and a lifecycle management mechanism for quality inspection of the UI core layer and the UI system layer are provided, so that different functions of the web application can be displayed in the UI core layer and the UI system layer, that is, different functions of the same web application are displayed in multiple layers simultaneously, thereby improving user experience.

In order to implement a mechanism for supporting multi-layer display by a web application, an embodiment of the present invention provides a display device, including: a display configured to present a user interface for displaying different functions of a web application; the controller is connected with the display and is used for splitting a UI layer of the displayed webpage application into a UI Core layer (UI-Core) and a UI System layer (UI-System) so as to perform different functions of the multi-layer display webpage application. The displayed web application refers to a previously started web application, namely an application which is presented at the forefront in a user interface of a display and can be seen by a user.

A schematic diagram of a new graph-layer relationship is illustrated in fig. 9, in accordance with some embodiments. Referring to fig. 9, the UI kernel Layer is located at the bottom of the top Layer of the OSD (i.e., Layer1), which is APL and Google asset, respectively, and the UI system Layer is located at the top Layer of the OSD (i.e., Layer 1).

In some embodiments, the UI system layer is located at a top layer of the OSD, and the UI system layer is used for displaying system functions required to be displayed at the top layer of the OSD in the web application; the UI core layer is positioned at the bottom layer of the top layer of the OSD and used for displaying bottom layer functions which need to be displayed at the bottom layer of the top layer of the OSD in the webpage application.

After splitting the UI layer into a UI core layer and a UI system layer, in some embodiments, the UI core layer and the UI system layer interact with each other through an APM (Application Program Manager) and a TV Main process for facilitating communication.

A relationship diagram of functional modules in a display device according to some embodiments is illustrated in fig. 10. Referring to fig. 10, when a certain web application is displayed in the UI layer, that is, the UI system layer and the UI core layer of the web application are displayed in the browser displayed in the display, new applications Google Assistant and Amazon APL are started, at this time, the display priorities of the four functions of the UI core layer, the UI system layer, the Google Assistant and the Amazon APL are: UI System layer > Google Assistant > Amazon APL > UI core layer. Window Window1.1 corresponding to the UI system layer is positioned at the forefront, window Window1.4 corresponding to the UI core layer is positioned at the rearmost, and windows Window1.2 and Window1.3 corresponding to Google Assistant and Amazon APL respectively are sequentially positioned between window Window1.1 and window Window1.4.

For control and data transmission, the UI kernel layer, the UI system layer, the Google assist and the Amazon APL all need to interact with a controller in the display device through the application management module and the main process. The controller in the display device is used as a bottom platform and is respectively connected with the application management module and the main process, so that the controller transmits data or notification, instructions and the like to the application management module and the main process.

The UI core layer and the UI system layer can not be directly interacted, and data transmission or control is carried out by means of the application management module and the main process. When the UI core layer requests the UI system layer to realize a certain function, the UI core layer sends a request/instruction to the application management module, and the application management module forwards the request/instruction to the UI system layer so as to establish the communication between the UI core layer and the UI system layer; when the UI system layer requests the UI core layer to realize a certain function, the UI system layer sends a request/instruction to the application management module, and the application management module forwards the request/instruction to the UI core layer so as to establish communication between the UI system layer and the UI core layer; therefore, the UI core layer and the UI system layer are communicated through the application management module.

In order to ensure real-time interaction between the UI core layer and the UI system layer and accurately respond to the corresponding functions, data synchronization between the UI core layer and the UI system layer is required to implement data sharing. To this end, in some embodiments, data sharing between the UI core layer and the UI system layer is achieved using a host process. The UI core layer sends the corresponding real-time data to the main process for storage, and the UI system layer also sends the corresponding real-time data to the main process for storage. All data required by the display device for presenting the intelligent television function, including channel information, program information, volume information, personalized setting parameters and the like, are stored in the main process.

The data stored in the main process is accessible to all web applications configured in the display device, and the application accesses the data in two ways including, but not limited to: one is that each web application establishes communication connection with the main process, and can actively acquire data stored in the main process; and the other is that when the data stored in the main process changes, the corresponding UI core layer and the UI system layer of each webpage application can be informed in real time, so that the UI core layer and the UI system layer can update corresponding data in time, and the UI picture effect is ensured. The data transfer process and the process of sending the request/instruction can be seen in the solid line portion of fig. 10.

When a new application is started, such as Google Assistant and Amazon APL, the application management module controls the display of the Google Assistant and the Amazon APL, namely the display layer position of the Google Assistant and the Amazon APL is controlled, so that a plurality of webpage applications are displayed by a plurality of layers at the same time, and the sequential display of the webpage applications on different layers is ensured. The control process can be seen in the dashed line in fig. 10.

Therefore, when the mechanism that the webpage application supports multi-layer display is executed, the display device provided by the embodiment of the invention can support the display of different functions of the same webpage application on different layers, and can also support the sequential display of multiple webpage applications on different layers, so that the user experience is improved.

An interaction diagram between applications according to some embodiments is illustrated in fig. 11. And performing real-time interaction between the UI core layer and the UI system layer, wherein the UI core layer and the UI system layer are required to establish a connection relation with the application management module respectively. In some embodiments, in establishing the connection relationship, the application management module is further configured to:

step 011, after the web application is started, respectively receiving the registration information sent by the UI core layer and the UI system layer.

Step 012, establishing a communication connection between the local terminal and the UI core layer based on the registration information transmitted by the UI core layer, and establishing a communication connection between the local terminal and the UI system layer based on the registration information transmitted by the UI system layer.

When a certain web application has been launched in the display device, a user interface of the web application is presented in the display. The method comprises the steps that a controller in the display device divides a UI layer used for presenting a user interface of the web application into a UI core layer and a UI system layer, after the display device is started and the web application is started, the controller starts an application management module and simultaneously starts the UI core layer and the UI system layer corresponding to the web application.

Referring to fig. 11 (a), after the UI core layer and the UI system layer of the same web application are started, corresponding registration information is respectively sent to the application management module to establish connection with the application management module, so as to implement communication between the UI core layer and the UI system layer. The registration information comprises a registration mode, an object, state information and the like, wherein the registration mode is used for representing a registration means which can be supported by the UI core layer and the UI system layer and the application management module respectively; objects are used to convey messages, as aggregates of data, providing an interface to send and receive messages; the state information comprises the starting states of the UI kernel layer and the UI system layer, and the UI kernel layer and the UI system layer send the state information to the application management module to inform the application management module that the UI layer is started.

After the application management module receives the registration information of the UI kernel layer, the communication connection between the application management module and the UI kernel layer can be established; after the application management module receives the registration information of the UI system layer, the communication connection between the application management module and the UI system layer can be established. After the application management module establishes communication connection with the UI core layer and the UI system layer respectively, communication between the UI core layer and the UI system layer can be achieved.

After communication is established between the UI core layer and the UI system layer, the UI core layer can send a request/instruction to the UI system layer through the application management module, and meanwhile, the UI system layer can also send the request/instruction to the UI core layer through the application management module.

In some embodiments, when the UI system layer sends a request/instruction to the UI core layer, the application management module is further configured to perform the steps of:

and step 021, receiving request information sent by the UI system layer.

And 022, sending the request information to the UI core layer, and establishing communication connection between the UI system layer and the UI core layer.

Referring to fig. 11 (b), in an actual application, if there is a request/instruction that the UI system layer needs to send to the UI core layer to request the UI core layer to perform a certain function, request information including the request or instruction is sent by the UI system layer to the application management module. After receiving the request information sent by the UI system layer, the application management module forwards the request information to the UI core layer, and the UI core layer receives the request information and can execute corresponding actions, at the moment, communication connection between the UI system layer and the UI core layer is established through the application management module.

In some embodiments, when the UI core layer sends the request/instruction to the UI system layer, the application management module is further configured to:

step 031, receive the request information that UI core system layer sends;

step 032, sending the request information to the UI system layer, and establishing a communication connection between the UI core layer and the UI system layer.

Referring to fig. 11 (c), in an actual application, if there is a request/instruction that the UI core layer needs to send to the UI system layer to request the UI system layer to perform a certain function, request information is sent by the UI core layer to the application management module, and the request information includes the request or instruction. After receiving the request information sent by the UI core layer, the application management module forwards the request information to the UI system layer, and the UI system layer receives the request information and can execute corresponding actions, at the moment, communication connection between the UI core layer and the UI system layer is established through the application management module.

For example, when the UI core layer controls the UI system layer to display the system function, the UI core layer sends a system function display instruction to the application management module, the application management module forwards the system function display instruction to the UI system layer, and the UI system layer displays the system function in response to the system function display instruction.

As can be seen, the controller in the display device splits the UI layer into a UI core layer and a UI system layer, and the application management module implements communication between the UI core layer and the UI system layer. After the communication connection between the UI core layer and the UI system layer is established, the system function can be displayed on the UI system layer when a new application is started, the new application is prevented from being shielded, a user can always view the system function, and the user experience is improved.

FIG. 12 is a flow diagram illustrating a method for a web application to support multiple layer display in accordance with some embodiments; an interaction diagram illustrating a method for a web application to support multiple layer display in accordance with some embodiments is illustrated in FIG. 13. In order to facilitate the web application to be displayed in multiple layers, an embodiment of the present invention provides a display device, where an application management module configured in a controller is used to execute the method for supporting multiple layer display for a web application shown in fig. 12 and 13, so that system functions of a previously started web application are displayed on a top layer of an uppermost layer of an OSD. In particular, the application management module is configured to perform the following steps:

and S1, receiving a layer display instruction sent by the UI core layer, wherein the layer display instruction is an instruction generated after the UI core layer receives an application starting instruction for starting a specified application, and the specified application is an application needing to be displayed on the uppermost layer of the OSD.

When a web application is started in the current display device, all the related functions of the web application are displayed on the top Layer of the OSD (Layer1), i.e., the user interface content presented in the display is related to the web application.

And if the user starts other webpage applications again, the other webpage applications can shield the started webpage applications, and at the moment, the started UI core layer can send layer display instructions to the application management module to inform the UI system layer of displaying system functions.

In this process, referring to fig. 13 (a), when the user starts a new web application, that is, starts a specific application, an application start instruction is generated and sent to the UI core layer where the web application was previously started. After receiving the application start instruction, the UI kernel layer may determine that a new web application is started again in the current display device, and needs to display the system function on the top layer of the OSD, so as to be easily viewed by the user.

The newly launched web application may be one or more web applications, and the newly launched web application (designated application) is the web application that needs to be displayed on the top layer of the OSD, and the designated applications affect each other or affect, e.g., block each other, the previously launched web applications.

At this time, the UI core layer generates a layer display instruction based on the application starting instruction, sends the layer display instruction to the application management module, and forwards the layer display instruction to the UI system layer through the application management module.

And S2, responding to the layer display instruction, displaying the specified function of the specified application between the UI core layer and the UI system layer, and sending the layer display instruction to the UI system layer, wherein the layer display instruction is used for instructing the UI system layer to display the system function of the web application.

After receiving the layer display instruction sent by the UI core layer, the application management module can display the specified function of the specified application on the top layer of the OSD and simultaneously send the layer display instruction to the UI system layer.

The layer display instruction carries display information, and the UI system layer receives the layer display instruction, so that the system function of the webpage application which needs to be started in advance is displayed based on the display information in the layer display instruction, namely the system function of the webpage application is displayed on the UI system layer.

At this time, the UI system layer is located at the top layer of the OSD, and the designated function of the designated application is displayed at the top layer of the OSD, that is, the designated function of the newly started designated application is located between the UI core layer and the UI system layer, so that the bottom function of the previously started web application is blocked by the designated function of the newly started designated application, and the designated function of the designated application is blocked by the system function of the previously started web application.

Because the system function is usually a volume bar, a device or a status prompt icon, etc., and the display frame is small, the area of the system function for shielding the specified function is small, and an effect that the system function of the previously started webpage application appears on the surface of the specified function of the specified application is presented.

It can be seen that, when the method for supporting multi-layer display by a web application is executed, based on the UI core layer and the UI system layer after splitting the UI layer, when a specific application is newly started, the UI core layer receives an application start instruction and sends a layer display instruction to the application management module, and the application management module sends the layer display instruction to the UI system layer, so that the UI system layer displays a system function of the web application. Therefore, the display equipment can perform multi-layer display on the same webpage application, when a new designated application is started, the bottom layer function of the webpage application started earlier is still displayed on the UI core layer (the bottom layer of the OSD uppermost layer), and the system function which needs to be displayed on the top layer of the OSD uppermost layer is displayed on the UI system layer, so that different functions of the same webpage application are displayed on different layers at the same time, and the user experience is improved.

In some embodiments, if the user needs to execute the step of returning or exiting a certain displayed web application, for example, exiting the display of the system function or exiting the presentation of a specific application, the UI kernel layer is still implemented by the application management module to execute the exiting operation on the UI system layer, at this time, the application management module is further configured to execute the following steps:

and step 31, receiving a layer exit instruction sent by the UI core layer.

And step 32, sending the layer exit instruction to the UI system layer, wherein the layer exit instruction is used for indicating the UI system layer to cancel the system function of the displayed webpage application.

Referring to fig. 13 (b), when the user performs an exit operation through the remote controller, an exit instruction is generated and transmitted to the UI kernel layer, and the UI kernel layer generates a layer exit instruction based on the exit instruction and transmits the layer exit instruction to the application management module. And the application management module forwards the layer exit instruction to the UI system layer, so that the UI system layer does not display the system function of the previously started webpage application any more.

Therefore, according to the display device provided by the embodiment of the invention, after the UI layer is split into the UI core layer and the UI system layer, the application management module realizes communication between the UI core layer and the UI system layer, so that when a new application is started, the system function of the previously started web application can be displayed on the UI system layer in time, the specified function of the newly started application is prevented from shielding the previously started web application, the system function which needs to be displayed at the forefront is displayed on the top layer (UI system layer) of the OSD uppermost layer, so that a user can conveniently view the system function, different functions of the same web application are simultaneously displayed through multiple layers, and the user experience is improved.

In some embodiments, in order to enable the split UI core layer and the UI system layer to share data in real time, the split UI core layer and the split UI system layer need to be implemented by using a host process configured in the display device.

An interaction diagram for data sharing according to some embodiments is illustrated in fig. 14. To this end, a host process for storing data is configured in the controller, and for data sharing, see fig. 14, the host process is configured to perform the following steps:

and step 41, receiving data storage instructions respectively sent by the UI core layer and the UI system layer.

And step 42, responding to each data storage instruction, and respectively storing the data corresponding to the UI core layer and the data corresponding to the UI system layer.

Referring to (a) in fig. 14, in order to implement data sharing, it is necessary to establish communication connections between the UI core layer and the UI system layer and the host process, respectively. Therefore, after the UI core layer and the UI system layer are started, respective data storage instructions are sent to the main process respectively.

After receiving a data storage instruction sent by the UI kernel layer, the main process stores data corresponding to the UI kernel layer; and after receiving the data storage instruction sent by the UI system layer, the main process stores the data corresponding to the UI system layer.

The data of the UI core layer and the data of the UI system layer are stored in the main process, so that the data sharing of the UI core layer and the UI system layer can be realized, the display synchronization of the display equipment in the content of the presented picture is ensured, and the user experience is improved.

Because the data stored in the main process is not only from the UI core layer and the UI system layer, but also from the data of other application modules in the controller, in order to ensure real-time sharing of the data, when the data stored in the main process changes, the UI core layer and the UI system layer need to be notified in time so as to ensure synchronization of the data. At this time, the host process is further configured to perform the steps of:

in step 51, when the stored data changes, a data change notification is generated.

Step 52, sending the data change notification to the UI core layer and the UI system layer, respectively.

Referring to fig. 14 (b), when the data stored in the main process changes, a data change notification is generated and sent to the UI core layer and the UI system layer, respectively, to notify the UI core layer and the UI system layer that the data in the controller has changed, and the respective data needs to be updated in time.

For example, if the user adjusts the playing sound of the display device, the volume parameter stored in the host process changes, and at this time, the UI system layer needs to synchronously display the adjusted volume value. In the process, the main process sends the volume parameter change notification to the UI core layer and the UI system layer, the UI core layer controls the UI system layer through the application management module to synchronize the numerical value on the volume bar to be the same as the new volume parameter, and therefore the user can be guaranteed to adjust the volume parameter again based on the numerical value displayed by the volume bar.

In some embodiments, when data corresponding to the UI core layer changes, the UI core layer needs to be synchronized to the host process for storage, and simultaneously notify the UI system layer to perform data synchronization, where the host process is further configured to perform the following steps:

and step 61, receiving a core data change notification carrying changed data sent by the UI core layer, wherein the core data change notification is used for representing that the data corresponding to the UI core layer changes.

And step 62, responding to the core data change notification, storing the changed data carried by the core data change notification, and sending the core data change notification to the UI system layer.

Referring to fig. 14 (c), when data corresponding to a UI kernel layer that previously starts a web application changes, the UI kernel layer sends a kernel data change notification to the host process, where the kernel data change notification carries changed data of the UI kernel layer. After receiving the core data change notification, the main process stores the changed data, and meanwhile forwards the core data change notification to the UI system layer so as to notify the UI system layer that the UI core layer has data update, and can acquire new data in time so as to ensure data synchronization of the UI system layer and the UI core layer.

In some embodiments, when data corresponding to the UI system layer changes, the UI system layer needs to synchronize to the host process for storage, and simultaneously informs the UI core layer to perform data synchronization, where the host process is further configured to perform the following steps:

and step 71, receiving a system data change notification carrying changed data and sent by the UI system layer, wherein the system data change notification is used for representing that the data corresponding to the UI system layer changes.

And step 72, responding to the system data change notification, storing the changed data carried by the system data change notification, and sending the system data change notification to the UI core layer.

Referring to fig. 14 (d), when data corresponding to a UI system layer that starts a web application first changes, the UI system layer sends a system data change notification to the host process, where the system data change notification carries changed data of the UI system layer. After receiving the system data change notification, the main process stores the changed data, and simultaneously forwards the system data change notification to the UI core layer so as to notify the UI core layer that data updating has occurred in the UI system layer, and can acquire new data in time so as to ensure data synchronization of the UI core layer and the UI system layer.

Therefore, according to the display device provided by the embodiment of the present invention, after the UI layer is split into the UI core layer and the UI system layer, the data sharing between the UI core layer and the UI system layer is realized by using the main process, and when data change occurs in the main process, the data change occurs in the UI core layer, or the data change occurs in the UI system layer, two parties other than the main process and the UI core layer are notified in time, so that the latest data can be stored in the main process, and the data synchronization update between the UI system layer and the UI core layer is ensured.
