Some built-in applications are preset in the display device, the built-in applications do not depend on a network, and a user can open the applications and view related information and resources in the applications under the condition that the device is not connected with the network. In some application scenarios, an electronic instruction book (E-manual) application, that is, an operation guide, is generally built in the smart television, a graphical user interface for prompting and guiding a user to operate is preset in the E-manual application, and the content of the operation guide is displayed in a form of loading HTML page data or PDF format files through a browser. The method and the device mainly aim at the problems existing when the display device displays the operation guide and provide a corresponding solution.

Clicking an application icon of the E-manual or opening the E-manual application through a Settings (Settings) entry, fig. 5 exemplarily shows a main page displayed when the operation guide is opened, the main page may include options of sub-pages such as "live tv" (LiveTV), "connect" (Connection), "Multi-screen" (Multi _ screen), "Smart Functions" (Smart Functions), "image and Sound" (Picture and Sound), "System and support" (access and System), "troubleshoot" (Troubleshooting) and "use the electronic specification" (Using the E-manual), when the display device is not connected to the network, each page (including the main page and each sub-page) of the E-manual application does not display a two-dimensional code, that is, when the user does not connect to the network, only sees the information resources preset by the operation guide, which are inherent information resources stored in the display device in advance, these information resources are not changeable and updatable.

When an operation guide is opened, detecting the networking state of the display equipment, if the networking state is detected to be that the network is connected, sending a URL request corresponding to the operation guide to a server, and the server acquires the latest content of the operation guide of the display equipment according to the URL request and issues the URL of a corresponding two-dimensional code; the display device generates the two-dimensional code after receiving the URL, and as shown in fig. 6, the operation instruction needs to refresh the page of the E-manual application in the presence of the network.

The refreshed page can display the generated two-dimensional code, so that the influence on user browsing caused by the fact that the two-dimensional code blocks the page is avoided, a thumbnail of the two-dimensional code can be displayed at a designated position of the page, the page displayed by referring to FIG. 7 is shown, the designated position is at the upper right corner of the page, the thumbnail of the two-dimensional code reduced by a certain multiple is displayed at the upper right corner of the page, the thumbnail of the two-dimensional code can be regarded as a two-dimensional code identifier and an entry for pushing an operation guide to a terminal device, a user can know that the two-dimensional code can be scanned by the terminal device when seeing the two-dimensional code identifier, the latest operation guide content is viewed in the terminal device, and the operation guide displayed by the terminal device at this time is full content comprising a main page and sub-pages. The terminal device can be a smart phone, a tablet and other electronic devices with two-dimensional code scanning functions, and can support IOS, android and other types of systems.

The two-dimensional code thumbnail can be displayed on a main page of the operation guide, and after a user clicks to enter each sub-page, the sub-page also needs to display the two-dimensional code thumbnail at a designated position, so that the user can scan the two-dimensional code at any time when opening any page of the operation guide. As shown in fig. 8, taking "real-time tv" as an example, clicking a "real-time tv" option on a main page to enter a "real-time tv" sub-page, displaying options such as channel search, channel edit, and channel list on the left side of the "real-time tv" sub-page, and after clicking any option on the left side of the sub-page, displaying corresponding information resources on the left side of the sub-page, where the information resources can be displayed to a user in the form of characters, images, tables, and lists, and displaying a thumbnail of a two-dimensional code on the upper right corner of the sub-page. It should be noted that, in this embodiment, the two-dimensional code identifier is visually presented in a thumbnail form in a comparative manner, and certainly, in practical applications, the two-dimensional code identifier may be in other forms, such as a "scanned two-dimensional code" displayed in characters, which is not limited in the embodiment of the present application.

After seeing the thumbnail/identification of the two-dimensional code, a user can click the thumbnail/identification of the two-dimensional code through a remote controller or touch control mode and the like, as shown in fig. 9, after the thumbnail of the two-dimensional code is clicked, an enlarged view of the two-dimensional code can be displayed on the upper layer of a current page, and prompt information for guiding the user to operate can be configured below the enlarged view of the two-dimensional code, for example, the prompt information in fig. 9 is that "please scan the two-dimensional code using your terminal, that is, an operation guide can be displayed on the terminal", and the prompt information can be adaptively set according to actual application. A user uses a two-dimensional code scanning function in the terminal device, for example, scans a two-dimensional code by "scanning" of an application program such as WeChat, and referring to fig. 10, the two-dimensional code is automatically scanned and recognized by the terminal device by aligning a scanning area with the two-dimensional code, and then the latest content of the pushed operation guide (i.e., online operation guide) is displayed in a content area of the terminal device; if the shooting environment is dark, the flash lamp can be started by clicking 'touch illumination', and illumination is improved to ensure that the two-dimensional code can be identified. As shown in fig. 11. It should be noted that the display form of the operation guide in the terminal is not limited, and the contents of the operation guide, such as page setting, layout, resource display, and the like, should be subject to practical application.

After the user successfully scans the two-dimensional code, in order to enable the enlarged image of the two-dimensional code not to cover the application page any more, the enlarged image of the two-dimensional code needs to be hidden, the two-dimensional code is displayed in a thumbnail mode again, and the user can click the enlarged image of the two-dimensional code to enable the enlarged image of the two-dimensional code to be hidden, wherein the mode is mainly based on manual operation of the user; or the terminal equipment automatically generates scanned indication information after responding to the successful scanning of the two-dimensional code and sends the scanned indication information to the display equipment end, the display equipment can control the enlarged image of the hidden two-dimensional code after receiving the scanned indication information, and the normal page display of the operation guide is resumed, so that the user does not need to manually hide the enlarged image of the two-dimensional code. It should be noted that the manner of hiding the two-dimensional code enlarged view is not limited to that described in this embodiment, and other forms, such as gesture control, other specified operation forms, and the like, may also be adopted in practical applications.

Fig. 12 shows an embodiment of an operation guidance display method, which is characterized in that a two-dimensional code is displayed on a graphical user interface corresponding to an operation guidance through a display device, a terminal scans the two-dimensional code, and pushes information resources of the latest operation guidance to the terminal, and the method is executed by configuring a controller 250 of the display device, that is, the controller 250 is an execution subject of the method, and the method includes the following program steps:

step S101, responding to a first input instruction, displaying a graphical user interface corresponding to an operation guide for guiding a user to use the functions of the display device.

Step S102, a networking state of the display apparatus is detected.

The first input instruction is an operation instruction input when the user starts the operation guidance function, for example, when the user clicks an application icon of the operation guidance through the control device 100 such as a remote controller, the user interface 265 of the display device receives the first input instruction; or, for a display device supporting screen touch, the first input instruction is generated when the user applies an icon to the touch operation guide. The preset page of the operation guide, information resource and other contents are stored in the memory of the display device in advance, so that the operation guide can be called and displayed at any time, and the operation guide can be loaded and displayed when the display device is not connected with the network.

Each time a user operates the application of the operation guide, a user graphical interface corresponding to the operation guide needs to be displayed on the display first, where the graphical user interface may be a main page of the operation guide or a sub-page entered according to the user operation, and when the display device receives a first input instruction, the display device also needs to detect a networking state of the display device, where the networking state includes a connected network and a disconnected network, and step S101 and step S102 may be executed simultaneously. The network state of the whole equipment can be directly detected in a conventional mode; or a networking state is detected by requesting a lightweight page using HTTP (hypertext Transfer Protocol). The method for detecting the networking state by using the HTTP to request the lightweight page specifically comprises the following steps: controlling a browser to access a lightweight page; when the lightweight page is normally accessed, namely the resources and the information of the lightweight page can be normally displayed, detecting that the networking state is that the network is connected; when the lightweight page displays the prompt information of access error or no network connection, namely the lightweight page is abnormally displayed, the networking state is detected to be the network disconnection, the access speed of the lightweight page is high, and therefore the detection efficiency of the networking state can be improved, and the lightweight page is a hundred-degree page and the like.

Step S103, judging whether the networking state is that the network is connected. If yes, namely when the networking state is detected to be that the network is connected, executing step S104; otherwise, if it is detected that the networking state is network unconnected, step S107 is performed.

And step S104, sending a URL request corresponding to the operation guide in the server to the server.

When the fact that the display device is connected with the network is detected, the operation guide loads and displays information resources of the operation guide on the display device according to information of country, language, device brand and the like, namely after the operation guide is started and before the two-dimensional code is not obtained, a display displays a page preset by the operation guide. Meanwhile, a URL request corresponding to the two-dimensional code and the operation guide is sent to a server through an http network, and the URL request carries the brand and the model of the display device, the attribute information of the device, the country information, the language information and the like; the server responds to the URL request, acquires the latest operation guide content adapted to the display device, and issues a URL (Uniform Resource Locator) of a corresponding two-dimensional code for the display device according to the acquired latest operation guide content.

And step S105, receiving the URL issued by the server, and generating a two-dimensional code according to the URL.

When the URL of the two-dimensional code is received, the two-dimensional code corresponding to the operation guide is generated according to the URL, and after the two-dimensional code image is obtained, the page of the operation guide can be refreshed.

And S106, controlling a display to display the two-dimensional code on a graphical user interface corresponding to the operation guide so that a user can scan the two-dimensional code by using terminal equipment to view the operation guide.

After the page is refreshed, the thumbnail of the two-dimensional code is displayed at the designated position, and other pages of the operation guide also need to be synchronously added with the thumbnail of the two-dimensional code at the designated position, for example, if the current page of the operation guide is a main page, the thumbnail of the two-dimensional code needs to be added at the upper right corner of the main page, and the thumbnails of the two-dimensional code needs to be synchronously added at the upper right corner of each sub-page under the main page, so that when a user clicks to enter any sub-page, the displayed thumbnail of the two-dimensional code can be seen at the upper right corner, the user can scan the two-dimensional code on any page of the operation guide, and after the scanning is completed, the information resource of the pushed operation guide is displayed in the terminal device immediately.

In this embodiment, when the user starts the operation guide, the networking state of the display device is detected, if it is detected that the network is connected, a URL request is sent to the server, then the generated two-dimensional code is displayed according to the URL of the two-dimensional code issued by the server, and after the terminal device scans the two-dimensional code, the information resource included in the pushed operation guide can be displayed on the terminal device. The server side can issue the URL of the corresponding two-dimensional code according to the latest content of the operation guide, and as long as the display equipment is connected with the network, the content of the operation guide can be synchronously updated and pushed to the terminal equipment through the two-dimensional code, so that the latest content of the operation guide can be displayed after the terminal equipment scans the two-dimensional code. The display device end displays original content when the operation guide is preset, the two-dimensional code is added to the operation guide in a network self-adaptive mode, a user can refer to guidance of the operation guide displayed by the terminal device, the display device is operated and set at the same time, resource pushing of the display device to the terminal is achieved, the experience function of the operation guide is improved, interaction between the display device and the terminal is improved, and user actual application experience is better.

When a user browses a page of an operation guide, the user can see a thumbnail of the two-dimensional code displayed at a designated position of the page, and at this time, the user can input a second input instruction, where the second input instruction is an operation instruction input by the user when the user amplifies the two-dimensional code, for example, the user can click the thumbnail of the two-dimensional code through a remote controller or touch control, and after the thumbnail of the two-dimensional code is clicked, an enlarged image of the two-dimensional code is displayed on an upper layer of the current page, and prompt information for guiding the user to operate can be configured below the enlarged image of the two-dimensional code. The two-dimensional code enlarged image is relative to a thumbnail, and the enlarged image can be an original two-dimensional code image acquired after a two-dimensional code URL is generated, or the thumbnail is properly enlarged by a certain multiple, but the definition of the image is ensured to ensure the accuracy of two-dimensional code identification, and the size of the enlarged image is moderate to avoid being too large or too small.

After the user successfully scans the two-dimensional code, in order to enable the enlarged image of the two-dimensional code to not cover the page, the enlarged image of the two-dimensional code needs to be hidden, namely, the two-dimensional code is restored to be displayed in a thumbnail form, so that the user can conveniently check the main content of the page, at this time, the user can input a third input instruction, wherein the third input instruction is an operation instruction input by the user when the user hides the enlarged image of the two-dimensional code, for example, the user can click the enlarged image of the two-dimensional code through a remote controller or touch control and the like to hide the enlarged image of the two-dimensional code, and the mode is mainly based on manual operation of the user; or the terminal equipment automatically generates scanned indication information after responding to the successful scanning of the two-dimensional code and sends the scanned indication information to the display equipment end, the display equipment can control the enlarged image of the hidden two-dimensional code after receiving the scanned indication information, and the normal page display of the operation guide is resumed, so that the user does not need to manually hide the enlarged image of the two-dimensional code. It should be noted that the manner of hiding the two-dimensional code enlarged view is not limited to that described in this embodiment, and other forms, such as gesture control, other specified operation forms, and the like, may also be adopted in practical applications. The display and hiding effects of the enlarged image of the two-dimensional code are not limited, for example, the enlarged image of the two-dimensional code is displayed in a pop-up, slide-out or gradual enlargement mode, and the enlarged image of the two-dimensional code is hidden by effects such as gradual reduction, dissolution and blurring.

And S107, not displaying the two-dimensional code on the graphical user interface corresponding to the operation guide.

When the display device is not connected with the network, the operation guide application can continuously display information resources loaded according to information of country, language, device brand and the like and preset in the local machine, namely, the operation guide application displays that a main page and each sub-page preset by a page operation guide preset by the operation guide do not display two-dimensional codes. When the network is in the connected state, according to the steps S104 to S106, the thumbnail of the two-dimensional code is additionally displayed at the designated position on the basis of the page preset by the operation guide.

In practical applications, the networking state of the display device may change, for example, when a user starts an operation guide, the display device is not connected to a network, but the device is networked in the process of browsing the operation guide, that is, the networking state is switched from the network unconnected state to the network connected state, and then a thumbnail of the two-dimensional code needs to be displayed in a refreshed page according to the above steps; if the networking state is changed from the network connected state to the network unconnected state, the display device side can maintain the two-dimensional code thumbnail displayed at the moment before the network disconnection because the two-dimensional code scanning is a network (such as 4G, 5G or WIFI) depending on the terminal device and not a network of the display device. Therefore, the network state in the application does not use a one-time acquisition mode, but the display of the two-dimensional code is adaptively adjusted according to the change of the network state.

In this embodiment, a real-time monitoring mode of network state change may be adopted, and once the broadcast information of the network state change is monitored, the page displayed by the display needs to be updated according to the newly acquired networking state; or, the network state of the display device is acquired at preset time intervals by using a mode of regularly monitoring the network state, and the preset time can be adaptively set according to factors such as actual network environment and application requirements, for example, 60 seconds.

In other possible implementations, during the display device running the operation guidance application, and the display device is always in the connected state of the network during the period, the two-dimensional code can be updated online in time, for example, the server detects that the operation guide of a certain display device has content update, a URL of a new two-dimensional code that fits the operation guide of the display device may be generated according to the updated contents, and issues the URL of the new two-dimension code to the display device, the display device refreshes the page according to the URL of the new two-dimension code, thereby updating the displayed two-dimensional code thumbnail, and prompting the user after the two-dimensional code is updated, as shown in fig. 13, such as scrolling or popping up prompt information on a page, the prompt message is that the two-dimensional code is updated, and a user can scan the new two-dimensional code to view the latest operation guide, and the prompt message can be adaptively set according to actual application. It should be noted that the display and update modes of the two-dimensional code can be flexibly set according to practical applications, and are not limited to the embodiment.
