And a selector in the user interface indicating that the item is selected, the position of the selector being movable by user input to change the selection of a different item.

It should be noted that the multiple view display areas may present display screens of different hierarchies. For example, a first view display area may present system-level item content (e.g., current properties, etc.), and a second view display area may present application-level item content (e.g., web video, VOD presentation, application screen, etc.).

Optionally, the different view display areas are presented with different priorities, and the display priorities of the view display areas are different among the view display areas with different priorities. If the priority of the system layer is higher than that of the application layer, when the user uses the acquisition selector and picture switching in the application layer, the picture display of the view display area of the system layer is not blocked; and when the size and the position of the view display area of the application layer are changed according to the selection of the user, the size and the position of the view display area of the system layer are not influenced.

The display frames of the same hierarchy can also be presented, at this time, the selector can switch between the first view display area and the second view display area, and when the size and the position of the first view display area are changed, the size and the position of the second view display area can be changed along with the change.

Fig. 7a is a schematic diagram of a user interface for a user selecting an electronic signage application in an application center, where the application is used to present signage information, and the signage information can be transmitted to a display device through a cloud application, or can be transmitted to the display device by the user through an external device interface 250 (e.g., a USB interface). The display device is mainly used for displaying the electronic label on the display device in a market mode, displaying system parameters, prices and product profiles so as to ensure that a background can monitor and manage sales of market products, and meanwhile, the situation that the label is independently configured around the display device to cause disordered management of the label and the products is avoided.

Optionally, the application program is not a system program, and can be downloaded in an application store or transmitted and installed for use through an external storage device. Or, the application program is a system program, and presents system parameters to the user.

Under the application of the electronic sign, the user may selectively cause the electronic sign to be presented in the first view display area 201, i.e., the sign information display area. Optionally, the label information display area is set as a system layer view display area.

Illustratively, as shown in FIG. 7 for a user entering a play screen 202 by selecting the application items of FIG. 5b via a selector, including the items of the applications 1-9, the electronic sign application, and providing a selector 40 indicating that any one of the items is selected, the position of the selector in the GUI can be moved by a user input operating the control device to change the selection of a different item.

It should be noted that an item refers to a visual object displayed in a GUI provided by a display device to represent corresponding content such as an icon, a thumbnail, a link, and the like. The presentation forms of items are often diverse. For example, the items may include text content and/or images for displaying thumbnails related to the text content. As another example, the item may be text and/or an icon of an application.

It should also be noted that the display form of the selector may be the focus object. The movement of the display focus object in the display apparatus 200 may be controlled to select or control items according to an input of a user through the control device 100. Such as: the user may select and control items by controlling the movement of the focus object between items through the direction keys on the control device 100. The identification form of the focus object is not limited. For example, as shown in fig. 7a, the position of the focus object is realized or identified by setting the background color of the item, and the position of the focus object may also be identified by changing the border line, size, transparency, and outline and/or font of the text or image of the focused item.

In fig. 7a, when the user operates the control means to instruct the selector 40 to select the electronic sign item, for example, the user presses a direction key on the control means, as shown in fig. 7b, the display device displays a GUI of the sign information setting page on the display in response to the key input instruction.

Fig. 7b schematically shows the operation between the control apparatus 100 and the display device 200 according to an exemplary embodiment. For example, as in FIG. 7b, the display device renders an electronic sign setup page when the user selects an application to enter the electronic sign via the remote control. The electronic sign setting page is presented on the playback screen 202, and includes an electronic sign customization field 2021 associated with the display device model, a sign display total switch 2022, an electronic sign template 2023, a template selection mark 2024, a price setting area 2025, and a sign position setting area 2026.

Specifically, in the electronic signage customization field 2021, the electronic signage application presents a specific model by reading the model information of the display device in the system attribute.

And a sign display master switch 2022 for controlling whether the electronic sign is in the sign information display area, if fig. 7b shows that the master switch is off, the electronic sign is not displayed on the display interface, and when the master switch is selected to be on by the remote controller, the electronic sign is displayed in the default area.

And the electronic label template 2023 is used for setting the display mode of the electronic label. In some embodiments, the electronic signage template includes a local template and a networking template, and the local template is selected by the user when the display device is not networked, and the background server data cannot be acquired. The networking template is provided by the background under the condition that the display equipment is networked. The template includes template data, specifically including price type, price font, price color, template color, etc.

In the template data, the price type is used to control whether the user can change the price, and there are two price types, including uniform price and flexible price. The price is unified, namely the price cannot be modified, the price of the machine type is uniformly controlled by a background, and market personnel cannot modify the price; the flexible price, namely the price, can be changed and can be edited by market personnel. Generally, when not networked, the price type defaults to a flexible price.

When the selector is in the position of template 1 and selects that template, a template selection marker is presented below it for prompting the user that template 1 is the currently selected template. When the user selects template 2, template selection tab 2024 is updated to be displayed below template 2.

The price setting area 2025 includes a retail price editing area and an active price editing area, the retail price editing area can edit the original price of the product, or the pricing editing area can edit the current selling price. When the price type is the elastic price, the price setting area obtains the selector and enters the editing mode; when the price type is a uniform price, the price setting area cannot acquire the selector.

The sign position setting region 2026 is used to set a display position of the electronic sign, which can be selected by the user through a selector, such as upper right, lower left, lower right, lower left, and the like.

As shown in fig. 7c, when the remote controller is selected to be on in the signboard display main switch, the electronic signboard is presented based on the setting information of the current electronic signboard setting page, the electronic signboard is displayed in the signboard information display area 201, the electronic signboard combines the template information and the price information of the user on the electronic signboard, and the electronic signboard is generated based on the selection of the user on the display position of the signboard and displayed in the corresponding area.

Fig. 8a-8d schematically show various presentation ways of presenting a signage information display area in a display device 200.

Fig. 8a-8d are schematic diagrams illustrating an exemplary presentation of an electronic label as a label information display area 201 floating on a top layer of a playback screen 202 after a user opens an electronic label switch and exits the electronic label settings page.

As shown in fig. 8a-8d, after the user accesses the electronic signage application, the application remains running, the priority level of the application can be set to be high to ensure that the application is not preferentially killed when the memory of the application is low, and the application can be automatically started until the display device stops running after being killed by the system.

Fig. 8a and 8b show the information display area of the sign presented by the user after selecting the local template of fig. 7 c. Illustratively, the sign information display area displays only the device model and the price information. In the local template, template information is stored locally. The local template includes a background picture and a text editing area.

Fig. 8c and 8d are GUIs of devices in a networked state, selecting the networking template of fig. 7 c. For example, after the electronic signage application is started, whether the device is networked or not is detected, and if the device is networked, the networking template, the price information and the product information are acquired through a background. At the electronic sign template of fig. 7c, a local template and a networked template are displayed.

In some examples, the user selects the activity template, one or more display information editing areas may be presented, the input text portion may be controlled by the control apparatus 100, such as a first display information editing area 2011 for editing and displaying product model and price, a second display information editing area 2012 for editing and displaying device information such as displaying the display device with high definition 4K functionality, and/or displaying the display device with O L ED screen.

It should be noted that the arrangement of the one or more display information editing regions can be changed in order, and one or more of them can be selectively displayed.

In some examples, the user selects the active template, and one or more background pictures may be presented in the signage information display area to show device information, which may include device brand (e.g., manufacturer AA), device model, device price, device characteristics (e.g., with high definition 4K functionality, O L ED TV), and store interaction information, which may be displayed in the form of pictures, video, text, and the like.

In some examples, the layout information is carried in the networked templates, such as in a landscape or portrait arrangement. Such as the GUI presented in fig. 8c for a user selecting a networked template to a vertical template. Fig. 8d is a GUI presented for a user selecting a networked template as a horizontal template.

In some embodiments, the display device may turn off the presentation of the signage information display in response to the user instructing to press the "mute" key twice in succession, but the application is still running in the background, and the display device may re-present the signage information display in response to the user instructing to press the "mute" key twice in succession. And under the condition of exiting from the playing picture of the electronic label setting page, the keys for indicating to display and close the label information display area can be set randomly through equipment.

As described in the above embodiments, when the display device displays a playing screen, based on the user input, the display device may provide the user with device information such as a device brand, a device price, a device characteristic, and the like, so that the user may know the device information of the display device when viewing the playing screen, thereby improving the user experience.

Fig. 9a-9b illustrate a flow chart of a method of displaying signage information.

With reference to the method shown in FIG. 9a, the method includes the following steps S91-S95:

step S91: the display presents a play picture. For example, the display may present the picture content shown in fig. 10.

Fig. 10 is a schematic diagram illustrating a play screen provided by the display device 200.

As shown in fig. 10, the display device may provide a play screen 202 to the display, which may be at least one of an image, text, program information, and video content. The playback screen is any screen that can be displayed on the application layer or part of the system layer of the display device, and is not limited to the above-mentioned picture content. For example, the playback frame shown in fig. 10 is a video frame.

Step S92: and receiving an instruction of a user to select to enter an application program for displaying the label information through the control device.

Optionally, after receiving the application program for displaying the label information, determining whether the application program is currently in a network connection state.

Step S93: an instruction for instructing display of the sign information is received, which is input by a user through the control device. For example, the user presses a menu key, a direction key, an OK key, a volume key on the control device or presses the menu key, the direction key, the OK key, the volume key and the like N times in succession, where N is a positive integer greater than 0.

Step S94: and in response to an instruction for displaying the sign information, triggered on an application program for displaying the sign information of the playing picture, a sign information display area floating on the upper layer of the playing picture is displayed on the display. The application for presenting signage information is, for example, the electronic signage application shown in fig. 7 c. And, in the GUI shown in fig. 8a to 8d, a sign information presentation page 201 is displayed on a playback screen 202 provided on the display, and the sign information presentation page 201 includes price information, system information, template information, and other text editing information or picture information.

Specifically, with reference to the method shown in fig. 7b, step S93 may specifically include the following steps:

step S941: receiving an instruction input by a user through a control device and instructing to start an application program for presenting the label information, and starting a first service to read and store the system information.

The first service is a background service and is used for acquiring system information and background data of the display device. First, system information, such as a device model, of a display device is acquired. If the equipment is in the networking state, partial label information to be displayed, such as price information and template information, is acquired from the server according to the model of the equipment and is further stored in a local database of the display equipment.

Optionally, after the application is started or the display device is started, the started first service is CloudService, where CloudService is an intservice, that is, the CloudService is automatically stopped after the data is acquired and stored.

Step S942: in response to an instruction to display sign information triggered on an application for presenting sign information of a playback screen, a second service is initiated to control a sign information display area to be presented on a display.

The second service is a window view service, and is used for calling the sign information stored in the local database, forming the sign information into a sign view, and displaying the sign view in a corresponding window.

Optionally, the second service is a WindowViewService, and is used to control logic for displaying and disappearing a signage display area.

Step S95: an instruction is received from a user via the control device instructing the sign information to be updated.

For example, after the user opens the sign information display area in the sign application program, default information is displayed, and the user can update the sign information by inputting price information, display position information, and text editing information.

Fig. 11 illustrates a flow diagram of another method of presenting a user interface in a display device 200 according to an embodiment. As shown in fig. 11, the method includes:

step S111: and acquiring the model data of the computer.

Here, an electronic signage application may be installed in the display device, which is managed and controlled by the background service process and the window view service process, for displaying signage information corresponding to the display device. Specifically, after the electronic signage application program is started or the display device is started, model data of the electronic signage application program, such as a model number, is acquired.

Step S112: judging whether the current state is in a network connection state; if yes, go to step S113.

Step S113: acquiring label information corresponding to the display equipment from the server according to the model data; the label information at least comprises price data of the model corresponding to the sale and template data used for displaying the model data and the price data.

Here, when it is determined that the mobile terminal is currently in the network connection state, the background service process may obtain, from a server (a display device manufacturer side), label information of the model number according to the model number, for example, sales price data corresponding to the model number and uniformly set by a manufacturer, function introduction data corresponding to the model number, template data used to display the model number, the sales price data, and the function introduction data, where the model number corresponds to data such as a position, a font type, a font color, and a font size in a template, and the sales price data corresponds to data such as a position, a font type, a font color, and a font size in the template.

The selling price data may include, among other things, a specific price and price type. The price type is used to indicate whether a particular price can be modified, facilitating the manufacturer in managing sales pricing for the display device. The price types include: the uniform price, namely the specific price is uniformly determined by the server and cannot be modified by market salesmen; the elastic price, namely the specific price can be modified by the sales staff of the market according to the actual situation after being issued by the server.

The template data may comprise the name of the template, position data of the template in the display, a background picture of the template. Optionally, the form is rectangular in shape. The position data of the corresponding template in the display may include the width, height, distance from the upper border of the display, distance from the left border of the display, or may include the position coordinates of the four vertices of the template shape relative to the display.

Step S114: and analyzing the label information, and updating the data in the label information to a local database.

Here, the sales price data, the function introduction data, the template data, and the like of the display device are acquired by analyzing the label information corresponding to the display device, and are updated to the local database.

Step S115: judging whether the label information needs to be displayed or not; if yes, go to step S116; otherwise, the flow ends.

Specifically, the display of the label information is controlled by a switch. The state of the switch in the current display equipment can be acquired, and if the state of the switch is on, the current information of the label needing to be displayed is determined; and if the state of the switch is off, determining that the label information does not need to be displayed currently.

Step S116: based on the template data, the display position of the template in the display is calculated.

Specifically, the display position of the template is calculated by calling the position data of the template in the local database in the display. For example, as shown in fig. 12, from the position data of template 1 in the display: and calculating the width and height of the template A, the distance X of the template 1 from the left boundary of the display and the distance Y of the template A from the upper boundary of the display, and displaying the template 1 on the upper left corner of the display. As another example, as shown in fig. 12, from the position data of the template 2 in the display: position coordinates (X) of four vertices of the shape of template 2₁，Y₁）、（X₂，Y₂）、（X₃，Y₃）、（X₄，Y₄) And calculating that the template 2 is displayed at the upper right corner of the display.

It should be noted that the data in the sign information (such as the width, height, distance from the boundary, etc. of the template) may be in units of pixels, and optionally, is designed based on the display size 1920 × 1080, so that for different display sizes, the data in the sign information needs to be converted to fit the display size of the current model.

Step S117: the model data and the price data are added to a template to assemble a signage view.

Here, first, the window view service process creates a placard view object.

The window view service process would then add the background picture of the template in the template data to the signage view object to set it as the background for the signage.

Then, the window view service process creates a text view object of the machine model, sets the attribute of the text view object according to the position, font type, font color, font size and other data of the machine model corresponding to the template, and adds the text view object to the placard view object.

Then, the window view service process creates a text view object of the selling price, sets the attribute of the text view object according to the data of the selling price data corresponding to the position, font type, font color, font size and the like in the template, and adds the text view object to the scutcheon view object. Wherein the editing attribute of the text view object is determined by the price type; if the price type is a uniform price, the editing attribute of the text view object is not editable; if the price type is an elastic price, the editing attribute of the text view object is editable.

In this way, a signage view is stitched for subsequent display in the display.

It should be noted that, whether function introduction data corresponding to the model of the display device (such as the advantage of the model) is displayed in the label information may be selected. Specifically, the window view service process creates a text view object of the functional introduction data, and accordingly, the text view object can be flexibly selected or added in the placard view.

Step S118: the window level of the display window corresponding to the signage view is set to keep it unobstructed.

It should be noted that, depending on the display content, the window hierarchy of the display window may be set. The display window with the high window level can shield the display window with the low window level; and the newly displayed display window can block the previously displayed display window. Illustratively, the window hierarchy may be represented numerically. The window type of the display window is divided into a system display window and an application display window, the lowest window level of the system display window is 2000, each increment of the numerical value by 1 represents that the window level is increased by one level, and the increment value is 2033 at most.

Here, in order to ensure that the display window corresponding to the signage view is not blocked by the display windows corresponding to other views, that is, the display window of the application program of the electronic signage is not blocked by the display windows of other application programs (such as a system notification application program, a screen saver application program, and the like), it is necessary to keep the window level of the display window of the application program of the electronic signage higher than the other display windows. For example, the window level of the display window of the application program of the electronic sign may be set to 2020 to ensure that the window level thereof is high.

Step S119: and displaying the display window corresponding to the label view in the display according to the display position.

Here, the display window corresponding to the placard view may be rendered on the display according to the display position calculated in step S106.

Thus, in the above example, since the display device manufacturer can uniformly issue and control the selling price of the display device through the backend server, it is possible to effectively control whether the television product in the marketplace can be changed in price and grasp the selling price condition of the television product. Furthermore, because the display device manufacturer can uniformly issue the display position and the display style of the label information in the display through the background server, such as the data of the template data, the font size and the color corresponding to the model data, and the like, the electronic label style of the brand television can be favorably realized.

It should be noted that, since the signage information needs to be displayed all the time in the display process of the shopping mall, in order to ensure that the electronic signage application is not killed first due to insufficient memory of the display device, in this embodiment, a service process for managing the electronic signage application needs to be maintained at a higher priority.

In general, the priority of an application process from high to low may be: persistent, Foreground, Visible, Perceptible, ServiceA, ServiceB, Cached. Where the persistence level requires that the application must be a preset application, and the electronic signage application in this embodiment needs to be downloaded or installed from an application store, so it cannot be set to this level. The foregorund level indicates that the application program process is being displayed in the Foreground and the user is currently interacting with the application program; for example, when an electronic signage application is opened, the priority of the electronic signage application process may become forego. The Visible level indicates that the application is Visible but not responsive to user actions; for example, when a setup application is opened on the electronic signage application interface, the priority of the electronic signage application process may become Visible.

As can be seen, since the electronic signage application is not a preset application and the application is not always in the foreground, the priority of the service process for managing the electronic signage application can be set to the Visible or the permissible level.

Further, if the electronic signage application is killed due to insufficient memory in the display device or other reasons, the service process for managing the electronic signage application needs to be immediately pulled up in order to ensure that signage information is always displayed.

Here, the service process may be set to a sticky start mode. The sticky start mode indicates that the service process can be automatically restarted after being unexpectedly suspended. In particular, the return value of the onStartCommand () method in the lifetime of the service process determines its stickiness. For example, the return value may be set to START _ STICKY, indicating that the service process is set to a STICKY START mode.

Thus, by setting the priority of the service process for managing the electronic signage application program, the electronic signage application program is guaranteed not to be killed preferentially when the remaining memory of the display device is low; through the setting of the starting mode of the service process for managing the electronic label application program, the electronic label application program can be ensured to work all the time, and label information is always displayed.

Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
