The electronic specification application on the display device includes an operation guide for guiding the user to use various functions of the display device, for example, the electronic specification includes content such as introduction of setting functions of the display device and introduction of parameters of the display device, which can help the user to set or adjust various parameters of the display device.

A display interface of the display device as shown in fig. 2, including an icon of an electronic specification application, such as the icon within the dashed box in fig. 2; a user can select an icon corresponding to the electronic specification on the display interface by operating the control device of the display device, and then the main interface of the electronic specification shown in fig. 3 is displayed on the display interface; the user can select specific options on the display interface of the electronic specification, such as options of 'live television', 'connection', 'multi-screen', and the like, and then can enter an introduction page for guiding the user to use the functions corresponding to the options.

When a user triggers and displays the electronic specification interface, the electronic specification interface is displayed on the display interface of the display equipment in a full screen mode; when the user triggers the display setting interface, the display setting interface is displayed at the designated position of the display interface or in a full screen mode. If the user needs to refer to the corresponding contents of the electronic specification when setting or adjusting the functional parameters of the display device in the setting interface, the user only needs to quit the setting interface first, then opens the electronic specification application program, finds the contents of the electronic specification which the user needs to refer to, quits the electronic specification application program again after reading, and enters the setting application program to continue the setting operation. Therefore, the electronic specification display method based on the display device needs complex operation and is poor in user experience.

The embodiment of the invention provides a display method of an operation guide based on display equipment, wherein the operation guide of the display equipment can be also called as an electronic specification of the display equipment. The embodiment of the invention can simultaneously display the electronic specification interface and the setting interface in the display area of the display equipment; for example, when a user triggers and displays an electronic specification interface corresponding to a specific function item, the electronic specification interface and a corresponding setting interface can be simultaneously displayed in a display area; or when the display device currently displays the setting interface, the electronic specification interface can be triggered to be displayed, and the setting interface and the electronic specification interface are simultaneously displayed in the display area.

Example one

The embodiment of the invention provides a scheme for displaying an electronic specification interface and a setting interface at the same time on the display equipment, and a user can set the functions of the display equipment while viewing the electronic specification interface.

The following describes the cases where the user triggers the display setting interface when the display device displays the electronic specification interface, and where the user triggers the display of the electronic specification interface when the display device displays the setting interface, respectively:

firstly, a user triggers a display setting interface when a display device displays an electronic specification interface

As shown in fig. 7, an embodiment of the present invention provides a display method of an operation guide based on a display device, including the following steps:

step S701, responding to the operation of displaying the electronic specification in a full screen mode triggered by a user, and displaying an electronic specification interface corresponding to an operation guide guiding the user to use the functions of the display device in the full screen mode on a display; the electronic specification interface comprises a plurality of selectable function items;

step S702, in response to the operation of selecting the electronic specification corresponding to the first function item in the plurality of function items and displaying the first function item, displaying an electronic specification interface on the display in a preset size smaller than a full screen, and simultaneously displaying a setting interface which is associated with the first function item and is used for configuring the first function related parameter.

According to the operation instruction display method based on the display device, provided by the embodiment of the invention, the display device responds to the operation of displaying the electronic specification corresponding to the first function item triggered by the user on the electronic specification interface, determines the setting interface corresponding to the first function item, and simultaneously displays the electronic specification interface and the setting interface corresponding to the first function item in the display area. According to the embodiment of the invention, when the user triggers and displays the electronic specification interface corresponding to the first function item, the electronic specification interface and the setting interface corresponding to the first function item can be simultaneously displayed in the display area of the display device, the user can directly perform setting operation on the setting interface according to the electronic specification without switching the display interface of the display device for many times, so that a more humanized display method is provided for the user, the auxiliary effect of the electronic specification application on the setting application is more obvious, the user operation is facilitated, and the user experience is improved.

After the user opens the electronic specification application, displaying an operation guide guiding the user to use the functions of the display equipment on a full screen on a display of the display equipment; the interface of the electronic specification comprises a plurality of function items which can be selected by a user, and the user can select any one of the function items through the control device of the display equipment.

For example, the user may operate a remote control device of the display device, control a selector on a display interface of the display device to move, and when the selector moves to a function item that the user needs to select, the user may input a determination instruction, thereby completing selection of the function item.

Responding to an input instruction for selecting a first functional item triggered by a user on an electronic specification interface, and acquiring a setting interface identifier contained in a corresponding electronic specification configuration file of the first functional item by a system server in the electronic specification system; the setting interface identification is pre-inserted into the electronic specification configuration file by the content editing module.

In one possible implementation, the electronic specification configuration file may be an HTM L file, and the Setting interface identifier included in the HTM L file is obtained in response to an input instruction triggered by a user on the electronic specification interface to select a first function item, for example, if the electronic specification interface corresponding to the first function item is an image specification interface, the corresponding Setting interface identifier may be a Setting Picture Setting interface.

And after the setting interface identification is obtained, the system server determines a setting interface corresponding to the first function item according to the setting interface identification. For example, if the acquired Setting interface identifier is < Setting > Picture </Setting >, it may be determined that the Setting interface corresponding to the first function item is an image Setting interface.

According to a possible implementation mode, the system server determines that a setting interface identifier included in an electronic specification configuration file of a first function item corresponds to a target calling function used for triggering and displaying a setting page corresponding to the first function item according to a corresponding relation between the setting interface identifier and the calling function, and packs a mapping of the target calling function in a system layer into a js file corresponding to the electronic specification.

In specific implementation, according to the acquired Setting interface identifier, determining a target calling function corresponding to the Setting interface identifier, for example, if the Setting interface identifier is < Setting > Picture </Setting >, the corresponding target calling function is startSetting ('Picture'), mapping and packaging the startSetting ('Picture') in a system layer into a js file corresponding to an electronic specification, and replacing the Setting interface identifier < Setting > Picture </Setting > in the HTM L file with an actually recognizable tag < input value ═ Picture "status" ("Picture") according to a corresponding relationship between the preset Setting interface identifier and an actually recognizable tag.

According to a possible implementation mode, a TV application end can map and call a packaging function of a system layer through window according to a target call function, and can map the packaging function to a js port through an addJavaScriptAsInterface () method of WebView, so that the target call function can call the packaging function, and a packaging function display setting interface is executed.

For example, assuming that the target calling function is "startSetting ('Picture')", the target calling function may be called to a system layer wrapper function startPq () through window mapping, and the wrapper function startPq () is mapped to a js port through addjavascript interface () method of WebView, so that the target calling function can call the wrapper function, thereby executing the wrapper function presentation image setting interface.

In one possible implementation, the TV application reduces the electronic specification interface displayed in full screen in the display area, and specifically, the width and height of the window occupied by the electronic specification interface may be reset by the WindowManager attribute L ayoutParam, where the reset width and height are not limited.

In one possible implementation, the setting interface is displayed in other areas except the area where the reduced electronic specification interface is located in the display area.

In specific implementation, in order to ensure that the electronic specification interface and the corresponding setting interface can be displayed at the same time, the setting interface is displayed in other areas except the reduced electronic specification interface.

In a possible implementation manner, the TV application sets the electronic instruction interface to be in a non-focalization state by adjusting the focus attribute of the electronic instruction interface, and sets the setting interface to be in a focalization state, that is, a user can control a selector in the setting interface to move by operating a control device of the display device, so as to select an option to be selected in the setting interface; therefore, the user can refer to the setting electronic specification interface and operate the setting interface at the same time.

Specifically, the attribute of the focus of the reduced electronic specification interface is set to F L AG _ NOT _ FOCUSAB L E, that is, the reduced electronic specification interface is set to a non-focusable state.

For example, as shown in fig. 8A, an electronic manual interface for image and sound adjustment is displayed, which includes image and sound function items. The content of the instruction corresponding to the image function item comprises an image mode function item and an image display parameter function item. When the selector is controlled to select the image display parameter function item based on the user input, as shown in fig. 8B, a specification interface corresponding to the image display parameter function item and a setting interface of the image display parameter are simultaneously displayed in the display area of the display device.

As shown in fig. 9, a complete flowchart of a first display method provided in the embodiment of the present invention includes the following steps:

step S901, responding to an operation of displaying an electronic specification in a full screen mode triggered by a user, and displaying an electronic specification interface in the full screen mode on a display of a display device, wherein the electronic specification interface comprises a plurality of selectable function items;

step S902, responding to an input instruction for selecting a first functional item triggered by a user, and acquiring a setting interface identifier in an electronic specification configuration file corresponding to the first functional item;

step S903, determining a target calling function which is corresponding to the setting interface identification and used for triggering the setting page according to the corresponding relation between the setting interface identification and the calling function;

step S904, calling a corresponding packaging function of a system layer of the display equipment through the determined target calling function;

step S905, executing a packaging function display setting interface;

step S906, the interface of the electronic specification displayed in the full screen mode in the display area is reduced, and setting interfaces are displayed in other areas except the area where the reduced interface of the electronic specification is located in the display area;

and step S907, setting the electronic specification interface to be in a non-focus-on state, and setting the setting interface to be in a focus-on state.

Secondly, the user triggers the interface for displaying the electronic specification when the display equipment displays the setting interface

As shown in fig. 10, an embodiment of the present invention further provides a display method of an operation guide based on a display device, including the following steps:

step S1001, responding to an operation of displaying a setting interface triggered by a user, and displaying the setting interface used for configuring the first function related parameters of the display equipment on the display in a first preset size;

step S1002, responding to an operation of displaying an electronic specification interface triggered by a user, and displaying the electronic specification interface corresponding to the first function in a second preset size while keeping displaying the setting interface; an operation guide for guiding a user to use a first function of the display device is displayed in the electronic specification interface.

In the embodiment of the invention, when the display area of the display equipment displays the setting interface, the setting interface and the corresponding electronic specification interface are simultaneously displayed in the display area of the display equipment in response to the operation of displaying the electronic specification interface triggered by the user, so that the user can refer to the corresponding electronic specification content in the setting process, a more humanized display method is provided for the user, the auxiliary effect of the electronic specification on the setting function is more obvious, and the user experience is improved.

In one possible implementation manner, when the setting interface is displayed in the display area of the display device, a user can trigger the display of the electronic instruction interface by pressing a preset key on a control device of the display device; or the user can trigger the electronic specification interface to be displayed by inputting a voice instruction of the electronic specification interface to be displayed.

It should be noted that the preset keys on the control device of the display device may be original keys of the control device, such as direction keys, and may define new additional functions for the direction keys; for example, when the setting interface is presented in the display area of the display device, if it is detected that the user presses the left direction key of the direction keys, the presentation of the electronic specification interface is triggered.

When the setting interface is displayed in the display area of the display device, the electronic specification interface identifier contained in the configuration file corresponding to the currently displayed setting interface is determined in response to the operation of displaying the electronic specification interface triggered by the user.

In a possible implementation manner, an electronic specification interface identifier may be stored in a configuration file corresponding to the setting interface in a SharePreFerence manner, and specifically, the electronic specification interface identifier may be a key-value pair representing a specific name of the electronic specification interface corresponding to the current setting interface, for example, if the current setting interface is an image setting interface, the corresponding electronic specification interface identifier may be a key-value pair having a key of "email" and a value of "picture".

The display device system layer sends a broadcast message containing the electronic specification interface identifier to the electronic specification system.

After receiving the electronic specification interface identification, a system server in the electronic specification system determines a configuration file corresponding to the electronic specification interface identification according to the corresponding relation between the electronic specification interface identification and the configuration file of the electronic specification interface.

For example, assuming that the electronic specification interface identifier is a key-value pair with a key of "email" and a value of "picture", it is determined that the configuration file corresponding to the electronic specification interface identifier is the HTM L file of the image specification interface according to a preset correspondence between the electronic specification interface identifier and the configuration file.

It should be noted that the electronic specification interface identifier may also be null, and when the main page currently displayed by the display device as the setting interface or the setting interface is not started, the electronic specification interface identifier is null; and when the interface mark of the electronic specification is empty, the corresponding configuration file is the configuration file of the main interface of the electronic specification.

And the TV application end displays the corresponding electronic specification interface according to the determined configuration file, wherein when the electronic specification interface is displayed, the width and the height of a window occupied by the electronic specification interface are reset through an attribute of Windows manager L ayoutParam.

The TV application end sets a window occupied by the electronic instruction book interface to be in a non-focus-on state and sets the setting interface to be in a focus-on state by setting F L AG _ NOT _ FOCUSAB L E, namely, a user can control a selector in the setting interface to move by operating a control device of the display equipment to select an option to be selected in the setting interface, so that the user can set the electronic instruction book interface according to the reference and operate the setting interface.

For example, as shown in fig. 11, when the display device displays the sound setting interface, and the user triggers an operation of displaying the electronic instruction book interface, the display device simultaneously displays the sound setting interface and the instruction book interface corresponding to the sound setting.

As shown in fig. 12, a complete flowchart of a second display method provided in the embodiment of the present invention includes the following steps:

step S1201, responding to the operation of displaying the setting interface triggered by the user, and displaying the setting interface in the display area of the display equipment;

step S1202, responding to an operation of displaying an electronic specification interface triggered by a user, and acquiring an electronic specification interface identifier contained in a configuration file corresponding to a setting interface;

step S1203, determining a configuration file of the electronic specification interface corresponding to the electronic specification interface identification according to the corresponding relation between the electronic specification interface identification and the configuration file of the electronic specification interface;

step S1204, displaying an electronic specification interface according to a configuration file corresponding to the electronic specification interface;

step S1205, reducing the electronic specification interface, and displaying the reduced electronic specification interface in other areas except the area where the setting interface is located;

and step S1206, setting the reduced electronic specification interface to be in a non-focus state, and setting the setting interface to be in a focus state.

Example two

The embodiment of the invention also provides a scheme for simultaneously displaying the electronic specification interface and the setting interface on the display equipment, and a user can set the functions of the display equipment while viewing the electronic specification interface.

An embodiment of the present invention provides a display method for an operation guide based on a display device, as shown in fig. 13, including the following steps:

step S1301, responding to the operation of displaying the electronic specification corresponding to the first function triggered by the user, and displaying an electronic specification interface corresponding to an operation guide guiding the user to use the first function of the display device on a full screen mode on the display;

step S1302, in response to an operation of converting a display mode of the electronic specification interface triggered by a user, displaying the electronic specification interface corresponding to the first function on the display in a first preset size smaller than a full screen;

and step S1303, responding to an operation of displaying a setting interface corresponding to the first function triggered by the user, and displaying the setting interface for configuring the relevant parameters of the first function in a second preset size while keeping displaying the electronic specification interface corresponding to the first function.

In one possible implementation, a user triggers an operation of starting an electronic specification application, and the display device displays a main interface of the electronic specification on a full screen on the display.

In a specific implementation, a user can control a selector on a display by operating a control device of a display device, select an icon corresponding to an electronic specification application in a display area, and trigger full-screen display of a main interface of the electronic specification on the display, wherein the main interface of the electronic specification comprises a plurality of functional items.

The display device displays the electronic specification main interface on the display, the electronic specification main interface can be added through a Windows manager, and specifically, the electronic specification main interface can be displayed on the display by calling a Windows manager.

When the electronic specification interface is displayed on the display in a full screen mode, a user can control the selector to select a first functional item on the electronic specification interface by operating the control device of the display equipment, and the electronic specification interface corresponding to the first functional item is triggered and displayed.

When the electronic specification interface corresponding to the first function is displayed on the display, a user can trigger the display mode of the electronic specification interface to be converted by pressing a conversion key preset in a control device of the display equipment, and the electronic specification application updates the display mode of the electronic specification interface by calling the WindowManager after monitoring the operation.

It should be noted that the conversion key preset in the control device of the display device may be an original key of the control device, for example, the number key 1, and may define a new additional function for the number key 1; for example, when the electronic specification interface is displayed on the display, if the fact that the number key 1 is pressed by a user is detected, the display mode of the electronic specification interface is triggered and converted;

or the preset conversion key in the control device of the display device can also be a volume key, a new additional function can be defined for the volume key, and when the electronic specification interface is displayed on the display, if the volume increasing or reducing key in the volume key is detected to be pressed by the user, the display mode of the electronic specification interface is triggered and converted.

In specific implementation, a windowmanager. updateview () method can be called to convert the display mode of the electronic specification interface into a non-focus suspension display mode for displaying the electronic specification interface in a first preset size; specifically, the electronic specification interface is reduced, and the reduced electronic specification interface is set to be in a non-focalization mode, that is, the selector on the display is no longer stopped on the electronic specification interface in the non-focalization suspension display mode.

In one possible implementation, the width and height of the window occupied by the electronic specification interface may be reset according to a first preset size through the WindowManager attribute L ayoutParam, wherein the width and height values in the first preset size may be set by the user or by using empirical values obtained through tests by a technician.

In one possible implementation, the reduced electronic specification interface is set to be in a non-focusable state by adjusting the focus attribute of the reduced electronic specification interface, so that a selector on a display does NOT stay on the electronic specification interface any more, and specifically, the focus attribute of the reduced electronic specification interface is set to be F L AG _ NOT _ focsab L E, that is, the reduced electronic specification interface is set to be in a non-focusable state.

For example, as shown in fig. 14, the display device presents a system setup specification interface for an unfocused hover state at a first preset size on the display.

When the electronic specification interface in the unfocused state is displayed in a first preset size on the display, a user triggers the operation of displaying the setting interface, and the setting interface used for configuring the relevant parameters of the first function is displayed in a second preset size while the electronic specification interface corresponding to the first function is kept displayed.

In a specific implementation, the operation of displaying the setting interface triggered by the user may be that the user selects an icon corresponding to the setting application in the display area by operating the control device of the display device to control the selector.

It should be noted that the icon corresponding to the setting application in the display area is located in other areas except for the area where the electronic specification interface with the first preset size is located in the display area.

According to one possible implementation mode, when the electronic specification interface corresponding to the first function and the main setting interface are simultaneously displayed on the display, the setting interface is in an upper focus state, namely a selector on the display is arranged on the setting interface, a user can control the selector by operating a control device of the display device, and the setting interface of the relevant parameter of the first function corresponding to the currently displayed specification interface of the first function is selected, so that the display device simultaneously displays the electronic specification interface and the setting interface corresponding to the first function on the display.

For example, as shown in fig. 14, a system setup specification interface is shown in a first preset size, and after the control selector selects an icon corresponding to the setup application based on the user input, the display is controlled to display the system setup interface again based on the user input, and as shown in fig. 15, a system setup electronic specification interface and a system setup interface are simultaneously shown on the display.

When the electronic specification interface corresponding to the first function and the setting interface are simultaneously displayed on the display, the user triggers the operation of converting the display mode of the electronic specification interface again, the display device displays the electronic specification interface corresponding to the first function on the display in a full screen mode, the electronic specification interface corresponding to the first function displayed in the full screen mode is set to be in a focus-up state, namely, the selector is moved to the electronic specification interface, so that the user can operate the control device of the display device to control the selector, quit the electronic specification interface corresponding to the current first function, and select the second function to display the electronic specification interface corresponding to the second function.

In a specific implementation, the width and the height of a window occupied by the electronic specification interface by the WindowManager, L ayoutParam attribute can be adjusted to the corresponding size when the display device displays the full screen, so that the electronic specification interface is converted to be displayed in the full screen, and the focus attribute of the electronic specification interface displayed in the full screen is adjusted to be in the upper focus state.

After a user selects and displays an electronic specification interface corresponding to a second function, responding to an operation of converting a display mode of the electronic specification interface triggered by the user, converting the display mode of the electronic specification interface corresponding to the second function into a non-focus suspension display mode for displaying the electronic specification interface in a first preset size, displaying a setting interface corresponding to the first function in a second preset size, and moving a selector to the setting interface, wherein the user can control the selector to select the setting interface for configuring related parameters of the second function by operating a control device of the display device, so that the display device can simultaneously display the electronic specification interface and the setting interface corresponding to the second function on the display.

As shown in fig. 16, a complete flowchart of a method for displaying an operation guide based on a display device according to an embodiment of the present invention includes the following steps:

s1601, in response to an operation of displaying the electronic specification corresponding to the first function in a full screen mode triggered by a user, displaying an electronic specification interface corresponding to an operation guide guiding the user to use the first function of the display device in the full screen mode on the display;
