After the kernel is started, shell and user application programs are loaded again. The application program is compiled into machine code after being started to form a process.

A schematic diagram of the software configuration in the display device 200 according to some embodiments is schematically shown in fig. 4. Referring to FIG. 4, in some embodiments, the system is divided into four layers, from top to bottom, an application layer (referred to as an "application layer"), an application framework layer (Application Framework layer) (referred to as a "framework layer"), a An Zhuoyun row (Android run) and a system library layer (referred to as a "system runtime layer"), and a kernel layer, respectively.

In some embodiments, at least one application program is running in the application program layer, and these application programs may be a Window (Window) program of an operating system, a system setting program, a clock program, a camera application, and the like; and may be an application program developed by a third party developer, such as a hi-see program, a K-song program, a magic mirror program, etc. In particular implementations, the application packages in the application layer are not limited to the above examples, and may actually include other application packages, which the embodiments of the present application do not limit.

The framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions. The application framework layer corresponds to a processing center that decides to let the applications in the application layer act. An application program can access resources in a system and acquire services of the system in execution through an API interface

As shown in fig. 4, the application framework layer in the embodiment of the present application includes a manager (manager), 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 to interact with all activities that are running in the system; a Location Manager (Location Manager) is used to provide system services or applications with access to system Location services; a Package Manager (Package Manager) for retrieving various information about an application Package currently installed on the device; a notification manager (Notification Manager) for controlling the display and clearing of notification messages; a Window Manager (Window Manager) is used to manage bracketing icons, windows, toolbars, wallpaper, and desktop components on the user interface.

In some embodiments, the activity manager is to: the lifecycle of each application program is managed, as well as the usual navigation rollback functions, such as controlling the exit of the application program (including switching the currently displayed user interface in the display window to the system desktop), opening, backing (including switching the currently displayed user interface in the display window to the previous user interface of the currently displayed user interface), etc.

In some embodiments, the window manager is configured to manage all window procedures, such as obtaining a display screen size, determining whether there is a status bar, locking the screen, intercepting the screen, controlling display window changes (e.g., scaling the display window down, dithering, distorting, etc.), and so on.

In some embodiments, the system runtime layer provides support for the upper layer, the framework layer, and when the framework layer is in use, the android operating system runs the C/C++ libraries contained 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 kernel layer contains at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (e.g., fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and the like.

In some embodiments, the kernel layer further includes a power driver module for power management.

In some embodiments, the software programs and/or modules corresponding to the software architecture in fig. 4 are stored in the first memory or the second memory shown in fig. 2 or fig. 3.

In some embodiments, taking a magic mirror application (photographing application) as an example, when the remote control receiving device receives an input operation of the remote control, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into the original input event (including the value of the input operation, the timestamp of the input operation, etc.). The original input event is stored at the kernel layer. The application program framework layer acquires 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 takes the input operation as a confirmation operation, wherein 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, the magic mirror application is started, and further, a camera driver is started by calling the kernel layer, so that a still image or video is captured through a 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) acted on a display screen by a user, 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 (e.g., multi-window mode) and window position and size corresponding to the input operation are set by the activity manager of the application framework layer. And window management of the application framework layer draws a window according to the setting of the activity manager, then the drawn window data is sent to a display driver of the kernel layer, and the display driver displays application interfaces corresponding to the window data in different display areas of the display screen.

An icon control interface display schematic of an application in a display device 200 according to some embodiments is illustrated in fig. 5. In some embodiments, as shown in fig. 5, the application layer contains at least one icon control that the application can display in the display, such as: 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 inputs from cable television, radio broadcast, 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, the video on demand application may provide video from different storage sources. Unlike live television applications, video-on-demand provides video displays from some storage sources. For example, video-on-demand may come from the server side of cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various multimedia content playing applications. For example, a media center may be a different service than live television or video on demand, and a user may access various images or audio through a media center application.

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

In some embodiments, when displaying a web application using a browser (e.g., a Cobalt) in a display device, 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, media playing function and the like. The core layer is connected with the butt joint layer and is used for realizing the communication between the core layer and a bottom layer platform (display device).

A window interface layer (window API) is configured in the docking layer for calling the underlying platform to create a window, and the window creation involves many attributes, such as wide cache, cache size, layer number (layer), etc. The layer number (layer) is used for finally fusing the contents rendered on different layers together so as to achieve the aim of realizing an interface with rich contents.

In implementing graphic composition, taking video playing in a display device as an example, the graphic composition needs to be implemented by using a video layer and an OSD (On Screen Display ) layer in video playing, where the video layer is used to implement video playing, and the OSD layer is used to display a playing picture. To facilitate graphical display, there is a distinction of priority between different layers, with high priority layers overlapping low priority layers. For example, the video layer has a lower priority than the OSD layer, that is, the OSD layer is displayed above the video layer when the video is played.

A display schematic of OSD layer priorities and applications according to some embodiments is illustrated in fig. 6. Referring to fig. 6, among OSD layers, layers of Layer0, layer1, layer2, etc. are generally included, and the priority of the three layers is Layer 2<Layer 0<Layer 1, and the arrow direction is the line of sight direction of the user, i.e., layer1 is located at the uppermost Layer and Layer2 is located at the lowermost Layer.

In some embodiments, when presenting a user interface of an application using a display device, the UI typically used to present the user interface is located at the uppermost Layer (Layer 1), the application is located at the middle Layer (Layer 0), where the application may be YouTube, amazon (a video website), EPOS (Electronic Point Of Sale electronic point of sale), and so on.

The applications of YouTube, amazon, EPOS (the three are located in Layer 0) and UI (the UI is located in Layer 1) are single page Web applications (SPA) based on browser implementation, i.e. Web applications. Because the related implementation of the interface of the Window interface layer (Window API) in the interface layer of the Cobalt browser only has windows with one attribute setting (such as hierarchy setting), that is, the Window created after each start of the current Cobalt is the same attribute, that is, each application is displayed at a fixed hierarchy after the start. However, as the variety of applications supported by the display device increases, new application requirements exist for presentation in Layer 1.

A display schematic of OSD layer priorities and new applications according to some embodiments is illustrated in fig. 7; a schematic display of a Layer1 Layer according to some embodiments is shown schematically in fig. 8. Referring to fig. 7 and 8, new applications that need to be exposed in Layer1 may be Google assant and Amazon APL (Alexa Presentation Language), in which case the applications of Google assant, amazon APL and UI layers are located in the same Layer 1.

Although the three are shown in the same Layer (Layer 1), there is also a fixed order among the three, e.g., google Assistant is at the forefront, APL times, UI is at the lowest. It can be seen that this arrangement will cause the part of the functionality of the UI that needs to be displayed at the forefront to be blocked, that is, when a new web application is launched, the newly launched web application will block the functionality of the previously launched web application (the application that has been displayed in the UI layer) that needs to be displayed at the uppermost layer, where the functionality of the web application that needs to be displayed at the uppermost layer includes a volume bar, a device or a status prompt icon, etc.

Therefore, to avoid the occurrence of occlusion, the above functions need to be displayed on the top Layer of the OSD (i.e., the uppermost Layer of Layer 1). In some embodiments, the function that needs to be displayed at the top layer of the OSD is taken 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 layer, all functions related to the UI are displayed in the same layer. For the top layer of the OSD where some functions are required to be displayed, when other functions are still displayed at the bottom layer of the OSD, the single-layer display method cannot be implemented, so that different functions of the web page 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, the embodiment of the invention provides a mechanism for supporting multi-layer display of the web application, which splits the UI layer into two different layers, namely a UI core layer and a UI system layer, and provides a communication mechanism, a data sharing mechanism and a life cycle management mechanism for quality inspection of the UI core layer and the UI system layer, so that different functions of the web application can be displayed in the UI core layer and the UI system layer respectively, that is, different functions of the same web application are displayed simultaneously in the multi-layer, thereby improving user experience.

In order to execute 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 the web application; the controller is connected with the display and is used for splitting the 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. Where a displayed web application refers to a previously launched web application, i.e., an application presented at the front-most, viewable by a user in the user interface of the display.

A schematic diagram of the new layer relationships according to some embodiments is illustrated in fig. 9. Referring to fig. 9, the UI core Layer is located at the bottom Layer of the OSD uppermost Layer (i.e., layer 1), and is respectively APL and Google assant in the upward order, and the UI system Layer is located at the top Layer of the OSD uppermost Layer (i.e., layer 1).

In some embodiments, the UI system layer is located at the top layer of the OSD, where the UI system layer is used to display a system function in the web application that needs to be displayed at the top layer of the OSD; the UI core layer is positioned at the bottom layer of the top layer of the OSD, and is used for displaying the bottom layer function which needs 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 order to facilitate communication, in some embodiments, interactions between the UI core layer and the UI system layer are performed through APM (Application Program Manager, application management module) and TV Main (Main process).

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 has been displayed in the UI layer, that is, the UI system layer and the UI core layer of the web application have been displayed in the browser presented in the display, new applications Google assant and Amazon APL are restarted, and at this time, the display priorities of the four functions of the UI core layer, the UI system layer, google assant and Amazon APL are respectively: UI system layer > Google Assistant > Amazon APL > UI core layer. Window windows 1.1 corresponding to the UI system layer are located at the forefront, window windows 1.4 corresponding to the UI core layer are located at the rearrear, windows 1.2 and windows 1.3 corresponding to the Google assant and Amazon APL are located between window windows 1.1 and window1.4 in sequence.

For control and data transfer, the UI core layer, the UI system layer, the Google Assistant, and the Amazon APL all need to interact with the controller in the display device through the application management module and the host process. The controller in the display device is used as a bottom layer platform and is respectively connected with the application management module and the main process so that the controller can transmit 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 cannot directly interact with each other, and data transmission or control is needed by means of an application management module and a main process. When the UI core layer requests to realize a certain function to the UI system layer, 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 communication between the UI core layer and the UI system layer; when the UI system layer requests to realize a certain function to the UI core layer, 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; it can be seen that the UI core layer and the UI system layer are implemented by the application management module for communication.

In order to ensure real-time interaction between the UI core layer and the UI system layer and accurately respond to corresponding functions, data synchronization between the UI core layer and the UI system layer is required, and data sharing is realized. To this end, in some embodiments, data sharing between the UI core layer and the UI system layer is implemented with 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 in 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 host process may be accessed by all web applications configured within the display device, the manner in which the applications access the data including, but not limited to, two types: one is that each web application establishes communication connection with the main process, and can actively acquire data stored in the main process; and when the data stored in the main process changes, the data can be notified to the UI core layer and the UI system layer corresponding to each webpage application in real time, so that the UI core layer and the UI system layer can update the corresponding data in time, and the UI picture effect is ensured. The data transmission process and the process of sending requests/instructions can be seen from the solid line portion of fig. 10.

When a new application is started, such as Google Assistant and Amazon APL, an application management module controls the display of Google Assistant and Amazon APL, namely the positions of the displayed layers are controlled, so that a plurality of web page applications are displayed by a plurality of layers at the same time, and the sequential display of the plurality of web page applications on different layers is ensured. The control process is shown in phantom 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, can also support the sequential display of a plurality of webpage applications on different layers, and improves the user experience.

A schematic diagram of interactions between applications according to some embodiments is illustrated in fig. 11. Real-time interaction is performed between the UI core layer and the UI system layer, and the UI core layer and the UI system layer are required to respectively establish a connection relationship with the application management module. In some embodiments, in establishing the connection relationship, the application management module is further configured to:

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

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

When a web application has been launched in the display device, a user interface for the web application is presented in the display. The controller in the display device splits the UI layer of the webpage application for presenting the user interface into a UI core layer and a UI system layer, and after the display device is started and the webpage 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 webpage 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 sent to the application management module respectively, so as to establish connection with the application management module respectively, and achieve 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 registration means which can be supported by the UI core layer and the UI system layer respectively with the application management module; the object is used for transmitting the message, and as a data aggregate, provides an interface for sending and receiving the message; the state information comprises the starting states of the UI core layer and the UI system layer, and the UI core layer and the UI system layer send the state information to the application management module so as to inform the application management module that the UI layer is started.

After receiving the registration information of the UI core layer, the application management module can establish communication connection between the application management module and the UI core layer; after receiving the registration information of the UI system layer, the application management module can establish communication connection between the application management module and the UI system layer. 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 realized.

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 the request/instruction to the UI core layer, the application management module is further configured to perform the steps of:

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

Step 022, the request information is sent to the UI core layer, and communication connection between the UI system layer and the UI core layer is established.

Referring to fig. 11 (b), in 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 a 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, and 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, receiving request information sent by the UI core system layer;

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

Referring to fig. 11 (c), in 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 including a request or instruction is sent by the UI core layer to the application management module. 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, and 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, and 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.

It can be seen that the controller in the display device splits the UI layer into a UI core layer and a UI system layer, and the communication between the UI core layer and the UI system layer is implemented by the application management module. 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, and the system function is prevented from being blocked by the new application, so that a user can always check the system function, and the user experience is improved.

A flowchart of a method for a web application to support multi-layer display according to some embodiments is illustrated in fig. 12; an interaction diagram of a method for a web application to support multi-layer display according to some embodiments is illustrated in FIG. 13. In order to facilitate the display of a web application on multiple layers, the embodiment of the present invention provides a display device, and the method for supporting the display on multiple layers by the web application shown in fig. 12 and 13 is executed by using an application management module configured in a controller, so that the system function of the web application started previously is displayed on the top layer of the OSD. Specifically, the application management module is configured to perform the steps of:

s1, receiving a layer display instruction sent by a UI core layer, wherein the layer display instruction refers to an instruction generated by the UI core layer after receiving an application starting instruction for starting a specified application, and the specified application refers to an application which needs to be displayed on the uppermost layer of an OSD.

When a web application is started in the current display device, at this time, the related functions of the web application are displayed in the uppermost Layer (Layer 1) of the OSD, that is, the user interface content presented in the display is the related function of the web application.

If the user starts the other web applications again, the other web applications will block the started web applications, and at this time, the started UI core layer may send a layer display instruction to the application management module to notify the UI system layer to display the system functions.

In this process, referring to fig. 13 (a), when a user starts a new web application, that is, starts a designated application, an application start instruction is generated and sent to the UI core layer that previously started the web application. After receiving the application starting instruction, the UI core layer can determine that a new webpage application is started in the current display device, and needs to display the system function on the top layer of the uppermost OSD layer, so that the system function is convenient to be checked by a user.

The number of newly launched web applications may be one or more, 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 the previously launched web application, for example, are blocked from each other.

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

S2, responding to the layer display instruction, displaying the appointed function of the appointed 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 indicating the UI system layer to display the system function of the webpage application.

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

The display information is carried in the layer display instruction, and the UI system layer receives the layer display instruction, so that the system function of the web application which is required to be displayed on the basis of the display information in the layer display instruction is known, namely, the system function of the web application is displayed on the UI system layer.

At this time, since the UI system layer is located at the top layer of the OSD and the specified function of the specified application is displayed at the top layer of the OSD, that is, the specified function of the newly started specified application is located between the UI core layer and the UI system layer, the specified function of the newly started specified application blocks the bottom layer function of the previously started web application and the system function of the previously started web application blocks the specified function of the specified application.

Since the system function is usually a volume bar, a device or a status prompt icon, etc., the display frame is small, so that the area where the system function shields the designated function is small, and an effect that the system function of the previously started web application emerges on the surface of the designated function of the designated application is presented.

Therefore, when the method for supporting multi-layer display by the webpage application is executed, the display device provided by the embodiment of the invention is based on the UI core layer and the UI system layer which are split to the UI layer, when the appointed application is newly started, the UI core layer receives the application starting instruction and sends the 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 the system functions of the webpage application. Therefore, the display device can perform multi-layer display on the same webpage application, when a new appointed application is started, the bottom layer function of the webpage application started before is still displayed on the UI core layer (the bottom layer of the uppermost layer of the OSD), and the system function required to be displayed on the top layer of the uppermost layer of the OSD is displayed on the UI system layer, so that different functions of the same webpage application are simultaneously displayed on different layers, and user experience is improved.

In some embodiments, if the user needs to execute the web application that returns to or exits from a certain display, for example, exits from displaying a system function, or exits from presenting a specified application, the UI core layer still executes the exiting operation on the UI system layer through the application management module, where 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 a 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 display webpage application.

Referring to fig. 13 (b), when a user performs an exit operation through a remote controller, an exit instruction is generated and transmitted to a UI core layer, and the UI core layer generates a layer exit instruction based on the exit instruction and transmits to an application management module. The application management module forwards the layer exit instruction to the UI system layer so that the UI system layer no longer displays the system function of the previously started webpage application.

Therefore, 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, system functions of a previously started webpage application can be timely displayed on the UI system layer, shielding of a designated function of the newly started application on the previously started webpage application is avoided, the system functions required to be displayed at the forefront are displayed on the top layer (UI system layer) of the uppermost layer of the OSD, the user can conveniently see, different functions of the same webpage application are simultaneously displayed through multiple layers, and user experience is improved.

In some embodiments, in order to facilitate the split UI core layer and the UI system layer to share data in real time, it is necessary to implement the split UI core layer and the UI system layer by using a main 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 main process for storing data is configured within the controller, for data sharing, see fig. 14, the main process being configured to perform the steps of:

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

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

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

After receiving a data storage instruction sent by the UI core layer, the main process stores data corresponding to the UI core 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 process of presenting the picture content 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 other application modules in the controller, in order to ensure real-time sharing of the data, the UI core layer and the UI system layer need to be notified in time when the data stored in the main process changes so as to ensure synchronization of the data. At this time, the main process is further configured to perform the steps of:

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

Step 52, the data change notification is sent 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 inform 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 main process will be changed, 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, and the UI core layer controls the UI system layer to synchronize the value on the volume bar to be the same as the new volume parameter through the application management module, so that the user can adjust the volume parameter again based on the value displayed by the volume bar.

In some embodiments, when the data corresponding to the UI core layer changes, the main process needs to synchronize to the main process to store, and inform the UI system layer at the same time, so as to synchronize the data, where the main process is further configured to perform the following steps:

step 61, receiving a core data change notification carrying changed data sent by the UI core layer, where the core data change notification is used to characterize that data corresponding to the UI core layer changes.

And step 62, responding to the core data change notification, storing 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 core layer that previously started a web application changes, the UI core layer sends a core data change notification to a main process, where the core data change notification carries changed data of the UI core layer. After receiving the core data change notification, the main process stores the changed data, and 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, so that new data can be timely acquired to ensure the data synchronization of the UI system layer and the UI core layer.

In some embodiments, when the data corresponding to the UI system layer changes, the main process needs to synchronize to the main process to store, and inform the UI core layer at the same time, so as to synchronize the data, where the main process is further configured to perform the following steps:

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

And step 72, responding to the system data change notification, storing 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 the data corresponding to the UI system layer that previously started the web application 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 forwards the system data change notification to the UI core layer so as to notify the UI core layer that the UI system layer has data update, so that new data can be timely acquired to ensure the data synchronization of the UI core layer and the UI system layer.

Therefore, after the UI layer is split into the UI core layer and the UI system layer, the display device provided in the embodiment of the invention uses the main process to realize data sharing between the UI core layer and the UI system layer, and timely notifies the other two parties except for the main process when the main process changes data, the UI core layer changes data or the UI system layer changes data, so that the latest data can be stored in the main process, and the synchronous update of the data between the UI system layer and the UI core layer is ensured.
