Description

A display device and text management method

Technical Field

The present application relates to the technical field of display devices, and in particular to a display device and a text management method.

Background Art

Display devices refer to terminal devices that can output specific display images, which can be terminal devices such as smart TVs, communication terminals, smart advertising screens, projectors, etc. Taking smart TVs as an example, smart TVs are based on Internet application technology, have open operating systems and chips, have open application platforms, can realize two-way human-computer interaction functions, and are TV products that integrate multiple functions such as audio and video, entertainment, and data to meet the diverse and personalized needs of users.

The user can input text into the display device to interact with the display device, for example, input search terms, passwords, network configuration parameters, etc. in the browser. The input text of the display device includes two types: general memory type and non-memory text type. Among them, the general memory type, that is, after inputting text into the display device, the display device can always display the text, and when editing the text again, the editing starts from the current existing text, such as the settings page for naming the display device. The non-memory text type, that is, the text input into the display device is only valid this time, and the original text content will not appear when editing again, and it needs to be re-edited, such as the password input page.

It is shown that the above methods are not convenient enough. For the first method, if the user wants to change the text to a historical text that has been entered before, he needs to re-enter it, which will take longer if it is a complex text. For the second method, when the user needs to remember many passwords, it is easy to forget or mix them up. Every time the password window is opened, it is necessary to constantly try and make mistakes, which is undoubtedly very inconvenient for the user and reduces the convenience of text input operations.

In some embodiments, the detector 230 is used to collect signals of the external environment or external interaction. For example, the detector 230 includes a light receiver, a sensor for collecting the intensity of ambient light; or, the detector 230 includes an image collector, such as a camera, which can be used to collect external environment scenes, user attributes or user interaction gestures; or, the detector 230 includes a sound collector, such as a microphone, etc., for receiving external sounds.

In some embodiments, the display 260 includes a display function component for presenting a picture, and a driving component for driving an image display. The display 260 is used to receive an image signal output from the controller 250 for display. For example, the display 260 can be used to display video content, image content, and components of a menu control interface and a user control UI interface.

In some embodiments, the communication device 220 is a component for communicating with an external device or server 400 according to various communication protocol types. The display device 200 may be provided with a plurality of communication devices 220 according to different supported communication modes. For example, when the display device 200 supports wireless network communication, the display device 200 may be provided with a communication device 220 including a WiFi function. When the display device 200 supports Bluetooth connection communication, the display device 200 needs to be provided with a communication device 220 including a Bluetooth function.

The communication device 220 can enable the display device 200 to communicate with the external device or server 400 by wireless or wired connection. Among them, the wired connection can connect the display device 200 with the external device through components such as data cables and interfaces. The wireless connection can connect the display device 200 with the external device through wireless signals or wireless networks. The display device 200 can establish a connection relationship with the external device directly, or indirectly establish a connection relationship through a gateway, a router, a connection device, etc.

In some embodiments, the controller 250 may include at least one of a central processing unit, a video processor, an audio processor, a graphics processor, and a power processor, and a first interface to an nth interface for input/output. The controller 250 controls the operation of the display device and responds to the user's operation through various software control programs stored in the memory. The controller 250 controls the overall operation of the display device 200.

In some embodiments, the controller 250 and the tuner-demodulator 210 may be located in different separate devices, that is, the tuner-demodulator 210 may also be located in an external device of the main device where the controller 250 is located, such as an external set-top box.

In some embodiments, the user input interface 280 may be used to receive instructions from a user.

FIG3 shows a software configuration diagram in a display device 200 according to some embodiments. In some embodiments, as shown in FIG3 , the system of the display device may include a kernel (Kemel), a command parser (shell), a file system, and an application. The kernel, shell, and file system together constitute the basic operating system structure, which allows users to manage files, run programs, and use the system. After power-on, the kernel starts, activates the kernel space, abstracts hardware, initializes hardware parameters, etc., runs and maintains virtual memory, schedulers, signals, and inter-process communication (IPC). After the kernel starts, the Shell and user applications are loaded. After startup, the application is compiled into machine code to form a process.

As shown in Figure 3, the system of the display device is divided into three layers, namely, the application layer, the middleware layer and the hardware layer from top to bottom. In some embodiments, the system of the display device also includes a UI layer (not shown in the figure), which is located above the application layer and receives data transmission from the application layer to realize the screen presentation of the display 260.

The application layer mainly includes commonly used applications on TV and application frameworks. Common applications are mainly applications developed based on browsers, such as HTML5 APPs and native APPs.

The Application Framework is a complete program model that has all the basic functions required by standard application software, such as file access, data exchange, etc., as well as the user interfaces of these functions (toolbars, status bars, menus, dialog boxes).

Native apps can support online or offline, message push or local resource access.

The middleware layer includes various TV protocols, multimedia protocols, system components and other middleware. The middleware can use the basic services (functions) provided by the system software to connect various parts of the application system or different applications on the network, and can achieve the purpose of resource sharing and function sharing.

The hardware layer mainly includes HAL interface, hardware and driver. Among them, HAL interface is the unified interface for all TV chips to connect, and the specific logic is implemented by each chip. Drivers mainly include: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

Based on the above display device 200 , the user can input text into the display device 200 to interact with the display device 200 , for example, input search terms, passwords, network configuration parameters, etc. in a browser.

In some embodiments, the input text of the display device 200 includes two types: a general memory type and a non-memory text type. Among them, the general memory type, that is, after inputting text into the display device 200, the display device 200 can always display the text, and when editing the text again, the editing starts from the current existing text, such as the setting page for naming the display device 200. The non-memory text type, that is, the text input into the display device 200 is only valid this time, and the original text content will not appear when editing again, and it needs to be re-edited, such as the password input page.

The above implementation is not convenient enough. For the first method, if the user wants to change the text to a historical text that has been entered before, he needs to re-enter it, which takes a longer time if it is a complex text. For the second method, when the user needs to remember many passwords, it is easy to forget or mix them up. Every time the password window is opened, it is necessary to constantly try and make mistakes, which is undoubtedly very inconvenient for the user.

In some embodiments, external devices such as a mouse and a keyboard can be connected through the device interface 240 to cooperate with the display device 200 to achieve fast text input. However, this method cannot view the text input history and cannot solve the problem of text memory and reuse.

In some embodiments, the text management of the display device 200 can be performed through the mobile terminal 300, that is, when the user inputs text to the display device 200, the input text can be broadcast to the display device 200 through the mobile terminal 300. However, this method relies on the text management system of the mobile terminal 300, and the text information of the display device 200 can only be managed on the terminal device 300, which is less convenient. In addition, it is necessary to configure the network environment for the mobile terminal 300 and the display device 200, authenticate the IP name of the display device, establish a local area network connection, and other complex steps, which are highly complex and reduce the user experience.

For example, when searching for program information by program name in the program guide (EPG), the user may forget the name of the program or channel that he watched yesterday, and the EPG does not provide viewing history. If the user wants to find the program again, he needs to keep turning pages in the EPG, which reduces efficiency. In addition to the EPG, there are also local browsers, applications that do not have a browsing history, such as the quick jump function of searching for application names, which also have the above-mentioned low efficiency.

Therefore, based on the above problems, some embodiments of the present application provide a text management method, which can free users from the repetitive text input process and improve the convenience of text input operations by setting a text management application to manage text on the display device 200. The text management application includes two scenarios, two implementation modes and two management methods.

Two scenarios: ordinary text storage/retrieval and password-type text storage/retrieval. For ordinary text that does not contain sensitive information, you can directly store/retrieve text through the text management application. For password-type text that contains sensitive information, you can set a password protection policy and configure an application lock for the text management application. When the user enters the correct application lock password, the storage/retrieval function of the text management application can be unlocked.

Two implementation modes: embedded mode and application mode. The embedded mode means that the text management application can be embedded in the soft keyboard application, and can be started in response to the operation of the soft keyboard application, and can be activated in the scene where text input is required. Among them, the soft keyboard control is a virtual keyboard displayed on the screen of the display device 200, including letter keys, number keys, symbol keys, confirmation keys, backspace keys and other operation keys. The user can control the soft keyboard control through the remote control or other control device 100 to realize text input, so that the user can enter search terms, email addresses, passwords, etc. The application scenarios of the soft keyboard application include name modification, WIFI connection password input, quick jump function of retrieving application names, browser search, local media application or U disk search for media resources, channel or application renaming, external device renaming, and EPG program table program retrieval, etc.

Application mode means that the text management application can be launched as an independent application, similar to a text memo, to display a list of texts stored in the device and to perform text editing, thereby increasing the functionality and flexibility of the text management application.

Two management modes: application management mode and public management mode, support text history management within the application and across applications. The former can realize quick location of text in the same application, and the latter can realize text reuse across applications, which is more convenient and quick.

In order to implement the above text management method, the display device 200 involves the background application management module (ApplicationManager, APM), front-end HTML5 display and other fields. The front-end HTML5 communicates with the middleware layer interface to control functions such as application management and key response. The display device 200 is mainly divided into a front-end UI module, an interface communication module, and a back-end implementation module according to the architecture.

The communication mode between the front-end and the back-end in the display device 200 can be implemented based on three interactive interfaces, namely, the acquisition (GET) interface, the setting (SET) interface and the notification (NOTIFY) interface. Among them, the GET interface is used by the front-end to obtain data information from the back-end. The SET interface is used by the front-end to store information to the back-end to realize the storage or update of information. The NOTIFY interface requires the front-end to subscribe. When the back-end status changes, the status change information will be sent to the subscribed front-end. The above three interfaces are used in combination to achieve the handshake between the front-end and the back-end.

For example, when the display device 200 is started, the browser will be initialized and set up, at which time the NOTIFY interface to be used can be registered in advance in HTML5.

As shown in Figure 4, it is a schematic diagram of the transmission path of the GET interface provided in the embodiment of the present application. The browser requests data information from the backend through the GET interface. The request is transmitted to the interface message processing module through the GET interface. The interface message processing module distributes the request to the middleware or APM module. The middleware or APM module returns the data information to the interface message processing module. The interface message processing module then transmits the data information back to the GET interface, and transmits the data information back to the browser through the GET interface.

As shown in FIG5 , a schematic diagram of the transmission path of the SET interface provided in an embodiment of the present application is provided. The browser requests data processing or data storage from the backend through the SET interface. The request is transmitted to the interface message processing module through the SET interface. The interface message processing module distributes the request to the middleware or APM module. The middleware or APM module processes or stores the data information.

As shown in Figure 6, it is a schematic diagram of the transmission path of the NOTIFY interface provided in the embodiment of the present application. When the state of the middleware or APM module changes, the state change information will be transmitted to the interface message processing module, and then transmitted to the NOTIFY interface through the interface message processing module, and the state change information will be sent to the browser through the NOTIFY interface.

In some embodiments, the specific data transmission method is as follows:

(1) Acquisition/storage of information data: When acquiring data information, the front end uses the GET interface to obtain whether the data is valid and whether it has read permission. When it is determined that the data is valid and has read permission, it then uses the GET interface to obtain the actual required data. Similarly, when storing information, the front end will first confirm whether it can be stored through the GET interface to prevent problems such as full memory/no permission. After receiving the information, the back end will feedback the available status to the front end, and then the front end will use the SET interface to store/update data to the back end.

(2) Switching applications: When the display device 200 switches applications, the backend sends a notification to the frontend through the NOTIFY interface. After receiving the notification, the frontend saves the relevant information and enables it when loading the update page.

(3) Key response: As shown in FIG. 7 , when the display device 200 receives the key value (key) of the key sent by the control device 100, the key information is passed to the keyboard stack, and the keyboard stack sends the key information to the key processing module in sequence, and the key information processed by the key processing module is sent to the APM module. If the front-end application registers the monitoring of the key with the APM module through the key registration interface, it will receive the key value of the key sent by the APM module through the NOTIFY interface. After receiving the key value, the front-end user interface (UI) module will trigger the corresponding user interface update or execute specific functions, such as navigation, character input, etc., to realize the interaction between the user and the display device 200.

The following describes how to start and exit the text management application from two implementation modes: embedded mode and application mode.

In some embodiments, as shown in FIG8 , the application mode entry of the text management application can be set on the main interface of the display device 200, which is the main screen interface of the display device 200. The main interface can display application icons of applications installed on the display device 200, and the user can start the corresponding application by clicking the icon. That is, when the display device 200 controls the display 260 to display the main interface, it can generate a start instruction for starting the text management application in response to the user input of the click instruction on the application icon of the text management application, thereby starting the text management application in the application mode.

In some embodiments, as shown in FIG8 , the application mode entry of the text management application can be set in the setting menu of the display device 200, and the setting menu is an interface for configuring various system settings and application characteristics in the display device 200. The text management application option is set in the setting menu, and the setting menu can be called, and the text management application can be started by clicking the text management application option in the setting menu. That is, when the display device 200 controls the display 260 to display the setting menu, a start instruction for starting the text management application can be generated in response to the user input of the selection instruction of the text management application option in the setting menu, thereby starting the text management application in the application mode.

For example, the display device 200 may display a setting menu as shown in FIG24, which includes a memo option, ie, an application mode entry of the text management application. The display device 200 may start the text management application in application mode in response to a user inputting a selection instruction for the memo option.

In some embodiments, when the display device 200 is running, it can receive a selection instruction for a target text box, which refers to an area for inputting text displayed on the screen of the display device 200, such as a search box, a login password box, etc. In response to the selection instruction, a soft keyboard application can be started, and the display 260 can be controlled to display a soft keyboard control corresponding to the soft keyboard application. By displaying a soft keyboard control that simulates the function of a physical keyboard on the screen, it is convenient for the user to input text.

In some embodiments, as shown in FIG8 , for the embedded mode of the text management application, the text management application can be started by a specific key on the control device 100. The APM module in the display device 200 can identify the key value of the specific key to trigger the start of the text management application. That is, when the display 260 displays the soft keyboard control, the first key value sent by the control device 100 is received, and the first key value is the key value of the first key in the control device 100. A start instruction for starting the text management application is generated according to the first key value, thereby starting the text management application in the embedded mode.

Based on the startup process of the text management application shown in FIG8 , when the display device 200 starts the text management application, it will obtain the current application information, and if it is determined that the current application environment is a soft keyboard application environment, the text management application will be started in the embedded mode. If it is determined that the text management application is currently started directly through the application mode entry, the text management application will be started in the application mode.

After starting the text management application, the text information managed by the text management application can be obtained, a text management page corresponding to the text management application is generated based on the text information, and the display 260 is controlled to display the text management page, which includes the stored historical input text. Based on the text management page, text storage, text editing and text reuse functions can be realized.

In some embodiments, the display device 200 may store the first text through the text management application in response to a text storage instruction of the first text input by the user based on the text management interface, where the first text is an unstored input text.

In some embodiments, the display device 200 can respond to a text editing instruction of a second text input by a user based on the text management interface, and perform a text editing operation on the second text in the stored historical input text through the text management application, where the second text is the stored historical input text. The text editing operation includes operations such as deletion, modification, and copying.

In some embodiments, the text management application can also be exited by pressing a button on the control device 100. That is, when the display device 200 runs the text management application, it receives the seventh button value sent by the control device 100. The seventh button value is the button value of the seventh button in the control device 100. For example, the seventh button can be a return button or an end button. An exit instruction for exiting the text management application is generated according to the seventh button value, thereby exiting the text management application.

Depending on the application mode, if the text management application is running in embedded mode, it will return to the soft keyboard page after exiting, that is, the display 260 cancels the display of the text management page of the text management application and displays the soft keyboard page. If the text management application is running in application mode, it will return to the main interface after exiting, that is, the display 260 cancels the display of the text management page of the text management application and displays the main interface.

The following describes the storage and retrieval of text information through a text management application from two scenarios: ordinary text storage/retrieval and password-type text storage/retrieval.

In some embodiments, the text management page corresponding to the text management application may include a primary text management page and a secondary text detail page. Among them, the primary text management page includes a historical input text item, that is, a stored historical input text item. The historical input text item includes the name of the historical input text, the application to which the historical input text belongs, and the storage time of the historical input text. The secondary text detail page is the historical input text corresponding to the historical input text item, that is, the detailed information of the text.

The display device 200 can respond to the start instruction for starting the text management application, start the text management application, and control the display 260 to display the primary text management page corresponding to the text management application. When the display 260 displays the primary text management page, the user can browse the historical input text items in the primary text management page.

When the detailed text of the target history input text item needs to be viewed, a selection instruction for the target history input text item can be input. In response to the selection instruction for the target history input text item, the display device 200 controls the display 260 to display the secondary text detail page corresponding to the target history input text item, and the secondary text detail page includes the target history input text corresponding to the target history input text item.

In some embodiments, text editing operations can be performed through the secondary text detail page, and the user can edit the historical input text in the page based on the secondary text detail page, so that the text management application can update the stored historical input text.

In some embodiments, when the text management application is started in embedded mode, the display device 200 exits the soft keyboard application, controls the display 260 to cancel the display of the soft keyboard control, and records the current first soft keyboard information of the soft keyboard application. The first soft keyboard information includes the input text entered in the target text box through the soft keyboard control, the cursor position of the cursor in the target text box, and the soft keyboard type parameter of the target text box. Among them, the soft keyboard type parameter is a setting value that characterizes the layout and functional characteristics of the soft keyboard, including language type (such as Chinese, English, Japanese, etc.), soft keyboard layout (such as numeric keyboard, symbol keyboard, etc.), uppercase and lowercase status, etc.

When the display device 200 exits the text management application, it restarts the soft keyboard application, obtains the recorded first soft keyboard information, and controls the display 260 to display the soft keyboard control according to the first soft keyboard information to restore the soft keyboard control to the display state before starting the text management application.

In this embodiment, by recording the soft keyboard information of the soft keyboard application when the text management application is started and the soft keyboard application is exited, when the text management application is exited and the soft keyboard application is restarted, it can be restored to the state before the text management application is started based on the recorded soft keyboard information.

In some embodiments, the text reuse function can be implemented through a text management application. As shown in FIG9 , when the display 260 displays the secondary text detail page corresponding to the target history input text item, the display device 200 can receive the second key value sent by the control device 100, and the second key value is the key value of the second key in the control device 100. In response to the second key value, the target history input text is copied to the clipboard, which is a public storage area in the display device 200 for subsequent reuse.

As shown in FIG9 , when the display 260 displays the soft keyboard page containing the soft keyboard control again, such as starting the soft keyboard page corresponding to the soft keyboard when the target text box is selected, or when the text management application is exited and the soft keyboard application is restarted, the display device 200 resumes displaying the soft keyboard page corresponding to the soft keyboard application. The display device 200 can receive the third key value sent by the control device 100, and the third key value is the key value of the third key in the control device 100. In response to the third key value, the target historical input text in the pasteboard is obtained through the soft keyboard application, and the target historical input text is pasted at the current cursor position of the target text box. Thus, text reuse is achieved.

In some embodiments, the text storage function can be implemented through a text management application. The text management page corresponding to the text management application may include a secondary new text page, which is used to perform text editing operations and text storage operations. When the display 260 displays the primary text management page, a fourth key value sent by the control device 100 is received, and the fourth key value is the key value of the fourth key in the control device 100. In response to the fourth key value, the control display 200 displays the secondary new text page, so as to interact with the user through the secondary new text page to implement text storage.

In some embodiments, when the text management application is started in embedded mode, in order to improve the user experience, the display device 200 exits the soft keyboard application, and when the text management application is started, the input text that has been entered in the target text box through the soft keyboard control is recorded. When the display 200 displays the secondary new text page, the recorded input text that has been entered in the target text box through the soft keyboard control can be filled into the secondary new text page. The user can edit the input text based on the secondary new text page. After the editing is completed, a storage instruction can be entered to store the edited input text through the text management application.

In some embodiments, a soft keyboard application can be enabled in a text management application to implement a text editing function. For the editing of the above-mentioned secondary new text page or secondary text detail page, the display device 200 can start the soft keyboard application in response to an editing instruction input by the user through the secondary new text page or the secondary text detail page. And obtain the second soft keyboard information of the secondary new text page or the secondary text detail page. The second soft keyboard information includes the current text information and cursor position in the secondary new text page or the secondary text detail page, as well as the soft keyboard type parameters of the text management application.

The display 260 is controlled to display a soft keyboard control according to the second soft keyboard information. At this time, the secondary new text page or the secondary text detail page can be edited through the soft keyboard control.

When the editing is completed, the display device 200 can respond to the exit instruction for exiting the soft keyboard application, exit the soft keyboard application, and control the display 260 to cancel the display of the soft keyboard control. At the same time, the page text content of the secondary new text page or the secondary text detail page after the soft keyboard control is edited is configured to the text management application. The secondary new text page or the secondary text detail page is updated according to the page text content by the text management application, and finally the display 260 is controlled to display the updated secondary new text page or the secondary text detail page.

Based on the above implementation, for the activation method of the soft keyboard application, there are two methods for starting the soft keyboard application based on the text management application: starting when editing the text management interface of the text management application and starting when the text management application running in the embedded mode exits. In this regard, the display device 200 can obtain the startup parameter string attached to the startup soft keyboard application when the interface is called, that is, param information, and through the startup parameter, it can be known which application starts the soft keyboard application.

For example, a text management application is used in a television, and its application name may be a television text management application (TTM). In this regard, if the string defined in the startup parameter param is "startup=TTMin", it means that the soft keyboard application is started when the text management application is editing text. If the string defined in the startup parameter param is "startup=TTMout", it means that the soft keyboard application is started when the text management application running in embedded mode exits.

As shown in FIG10 , if it is determined based on the startup parameters that the soft keyboard application is started when the text management application is performing text editing, the current text information and cursor position in the text management interface where the text management application needs to perform text editing, as well as the current soft keyboard type parameters of the text management application are obtained. The display 260 is controlled to display the soft keyboard control based on the text information, cursor position and soft keyboard type parameters.

If it is determined based on the startup parameters that the soft keyboard application is started when the text management application running in the embedded mode is exited, the text information, cursor position and soft keyboard type parameters of the soft keyboard application recorded when the text management application is started are obtained. The display 260 is controlled to display the soft keyboard control based on the text information, cursor position and soft keyboard type parameters, so that the soft keyboard control can be restored to the state before the text management application is started based on the recorded soft keyboard information.

If it is determined based on the startup parameters that another application is starting the soft keyboard application, the current text information and cursor position in the interface where the other application needs to edit text, as well as the soft keyboard type parameters of the other application, are obtained. The display 260 is controlled to display the soft keyboard control based on the text information, cursor position and soft keyboard type parameters.

As for the exit method of the soft keyboard application, there are two ways to exit the soft keyboard application when the text management application interacts with the soft keyboard application. The first way is to exit when the text management application is started. At this time, the soft keyboard application will actively save the current text information data and related configuration parameters, such as keyboard type, keyboard initial text, keyboard available switching language, etc. The second way is to exit after editing the text management interface (such as the secondary text detail page, the secondary new text page) of the text management application. After exiting the soft keyboard application, the edited text data needs to be passed to the text management application through the NOTIFY interface. Since the two exit methods are based on different key responses, the first method is to exit through the first key in the control device 100, and the second method is to exit through the seventh key in the control device 100, such as the return key or the end key. Two sets of key responses exit the process, so no additional parameters are required to determine which exit method is.

As shown in FIG11 , it is a flow chart of exiting a soft keyboard application when a text management application is started. When the soft keyboard application is running, the display device 200 can store the input text entered through the soft keyboard control, the current cursor position and the soft keyboard type parameter in response to the first key value sent by the control device 100. Exit the soft keyboard application and start the text management application.

As shown in FIG12, it is a flowchart of exiting the soft keyboard application after the text management interface of the text management application is edited. When exiting the soft keyboard application, the display device 200 can obtain the startup parameter param. If the string defined in the startup parameter param is "startup = TTMin", it is determined that the soft keyboard application is exited after the text management interface of the text management application is edited. The text information edited by the soft keyboard control can be transmitted to the text management application through the NOTIFY interface. The text management application will register the monitoring of the NOTIFY interface, thereby obtaining the edited text information transmitted through the NOTIFY interface, and displaying the edited text information in the current text management interface.

For example, take the control device 200 as a remote control and the target text box as a search box of a browser. The display device 200 can receive a selection instruction for the search box input by the user, and in response to the selection instruction, start the soft keyboard application, control the display 260 to display the soft keyboard control corresponding to the soft keyboard application, thereby presenting a soft keyboard page as shown in FIG13. The soft keyboard page includes a search box, a soft keyboard control, and a key indication window. The search box is used to display the text entered through the soft keyboard control. The key indication window is used to guide the user operation. Among them, "Red: Text Management" means that the user presses the Red key on the remote control to call the text management application.

Based on the indication of the key indication window in the soft keyboard page, the user presses the red key of the remote controller, and the remote controller can send the red key value of the red key to the display device 200. The display device 200 can start the text management application based on the red key value and control the display device 260 to display the first-level text management page shown in FIG14. At this time, the soft keyboard control will cancel the display, and the current soft keyboard information of the soft keyboard application will be saved to the underlying storage.

As shown in Figure 14, the text display order in the first-level text management page defaults to starting with the record closest to the current time. The information represented by each text item (row) includes the name of the text (such as namel-name8), the application to which the text belongs (such as a browser), and the time when the text was last saved. The button indication window at the bottom of the first-level text management page is used to guide user operations. Among them, "Yellow key: New" means pressing the yellow key on the remote control to create a new text. "Red key: Delete" means pressing the red key on the remote control to delete the text. "Green key: Local file" means pressing the green key on the remote control to switch to the text management application in the public management mode and display the historical input text of the entire machine. "OK: Detailed information" means pressing the OK button on the remote control to call the second-level detailed interface to display text detailed information. "△ ": Focus selection" means pressing the up and down keys on the remote control can select the focus. "《》: Page turning" means pressing the left and right keys on the remote control can turn the page. "BACK: Return" means pressing the BACK key on the remote control can return.

Based on the indication of the key indication window in the primary text management page, the user presses the yellow key of the remote control, and the remote control can send the yellow key value of the yellow key to the display device 200. Based on the yellow key value, the display device 200 can control the display 260 to display the secondary new text page as shown in Figure 15, and display the text content currently input through the soft keyboard control on the text line of the text content in the secondary new text page. The focus is in the input text box of the name by default. The key indication window below the secondary new text page is used to guide the user operation. Among them, "direction key" means pressing the direction key on the remote control to move the focus. For example, if the current focus is in the input text box of the name, if you press the down key of the direction key, you can switch the focus to the input text box of the text content. "OK: Modify/Confirm" means pressing the OK key on the remote control to perform a modification operation or a save operation. "Green: Copy" means pressing the green key on the remote control to copy the input text in the page. "BACK: Return" means pressing the BACK key on the remote control to return processing.

The display device 200 can respond to a click instruction of the input text box in the secondary new text page, start the soft keyboard application, and control the display 260 to display the soft keyboard control, whose initial display text is the text displayed under the current focus, so that the user can edit the text through the soft keyboard control, such as modifying the name.

It should be noted that in order to prevent multiple layers of application nesting, the soft keyboard application launched this time will not support the function of calling up the text management application with the red key, and only supports text editing.

Based on the indication of the key indication window in the secondary new text page, the user can press the OK key of the remote control after editing is completed, and the remote control can send a confirmation key value of the OK key to the display device 200. The display device 200 can save the input text in the secondary new text page through the text management application in response to the confirmation key value.

In order to improve the user experience, when the name and text content items in the secondary new text page are edited and not empty, they are automatically saved, and the input text newly created through the secondary new text page is displayed in the latest line of the primary text management page as shown in Figure 14. If the text entered in the name and text content items in the secondary new text page is incorrect, a prompt message is generated, such as the prompt message "Invalid name or text!", to prompt the user that the current text is incorrect.

Based on the indication of the button indication window in the primary text management page, the user presses the red button of the remote controller, and the remote controller can send the red button value of the red button to the display device 200. In response to the red button value, the display device 200 detects the current focus position and deletes the text item where the current focus is located. For example, if the current focus is located at the text item corresponding to name3 shown in FIG. 14, the text item corresponding to name3 is deleted.

The display device 200 may also display a prompt window as shown in FIG16 to prompt the user whether to delete the text. The user may switch the focus to the "Yes" control or the "No" control by using the arrow keys of the remote control and press the OK key of the remote control. When the display device 200 receives the confirmation key value of the OK key and the current focus position is on the "Yes" control, the text item will be deleted.

Based on the indication of the key indication window in the primary text management page, the user presses the OK key of the remote control, and the remote control can send the confirmation key value of the OK key to the display device 200. The display device 200 can control the display 260 to display the secondary text detail page shown in FIG17, that is, the detailed text corresponding to the name name3, based on the confirmation key value. The key indication window below the secondary text detail page is used to guide the user's operation. For specific indicated operations, please refer to the description of the key indication window of the secondary new text page mentioned above.

Based on the indication of the key indication window in the secondary text detail page, the user can press the green key of the remote control, and the remote control can send the green key value of the green key to the display device 200. In response to the green key value, the display device 200 can copy the text corresponding to the name name3 to the clipboard through the text management application to be set at the bottom layer for use by the soft keyboard application.

On any page of the above text management application, the user presses the EXIT key of the remote control, and the remote control can send the exit key value of the EXIT key to the display device 200. In response to the exit key value, the display device 200 exits the text management application, restarts the soft keyboard application, displays the soft keyboard control again, and reads the previously stored soft keyboard information to restore the soft keyboard control to the state before entering the text management application, thereby displaying the soft keyboard page shown in FIG. 18 .

When the text in the underlying clipboard is not empty, a new prompt message will be added to the key indication window in the soft keyboard page, that is, a new prompt message "Green: Paste text" will be added to the key indication window shown in FIG. 18, indicating that the user presses the green key on the remote control to paste the text.

Based on the indication of the key indication window in the soft keyboard page shown in FIG18 , the user can press the green key of the remote control, and the remote control can send the green key value of the green key to the display device 200. The display device 200 can obtain the detailed text corresponding to the previously copied name3 from the clipboard in response to the green key value, and paste the text to the current cursor.

The above is a common text storage/retrieval method. For the password-type text storage/retrieval method, the display device 200 will set a password protection policy and configure an application lock for the text management application. When the user enters the correct application lock password, the storage/retrieval function of the text management application can be unlocked. All password-type texts are managed through the application lock, reducing the time cost of user trial and error.

In some embodiments, when the display 260 displays the primary text management page, in response to the selection instruction of the target history input text item, the display 260 is controlled to display the password verification page. The password text entered by the user through the password verification page is obtained. The target password text is obtained. If the password text is the same as the target password text, it means that the password verification is passed, and the display 260 is controlled to display the secondary text detail page.

In some embodiments, if the password verification is passed, the display 260 can be controlled to display the secondary encrypted text detail page, wherein the secondary encrypted text detail page is a page after the target historical input text in the secondary text detail page is encrypted. When the display 260 displays the secondary encrypted text detail page, the display device 200 can receive the sixth key value sent by the control device 100, and the sixth key value is the key value of the sixth key in the control device 100. In response to the sixth key value, the display 260 is controlled to display the secondary text detail page.

For example, the display 260 displays the primary text management page shown in FIG. 19, which is different from the primary text management page shown in FIG. 14 in that when a password-type text is displayed on the primary text management page, a lock icon is displayed in front of the text item corresponding to the password-type text, and the lock icon indicates that the text is a password-type text. If the user wants to use the text, the user needs to first perform a password verification of the application lock of the text management application, or perform a password verification through the parental lock in the display device 200, and the text can be used only after the password verification is passed.

If the application lock of the text management application is used for password control, when the secondary text detail page needs to be displayed, the display device 200 controls the display 260 to display the password verification page as shown in Figure 20. If the parental lock is used for password control, when the secondary text detail page needs to be displayed, the display device 200 controls the display 260 to display the password verification page as shown in Figure 21.

It can be understood that, as shown in Figures 20 and 21, both the parental lock and the application lock are passwords consisting of 4 digits, which can be directly entered based on the number keys in the remote control without calling up the soft keyboard application.

The display device 200 can obtain the password entered by the user in the input box in the password verification page and perform password verification. If the password verification fails, the display device 200 will stay on the password verification page until the user presses the return key or the EXIT key to exit.

If the password verification is successful, the secondary encrypted text details page shown in FIG22 is displayed. The difference between the secondary encrypted text details page shown in FIG22 and the secondary text details page shown in FIG17 is that the text in the text content of the page is indicated by an "*". In addition, a new prompt message "青:查看" is added to the button indication window at the bottom of the page, indicating that the user presses the 青 button on the remote control to view the text.

Based on the indication of the key indication window in the secondary encrypted text detail page, the user can press the green key of the remote controller, and the remote controller can send the green key value of the green key to the display device 200. The display device 200 can control the display 260 to display the secondary text detail page as shown in FIG. 23 in response to the green key value.

Similarly, when a user deletes password text based on the primary text management page, a password verification page must be popped up first. After the verification is passed, a prompt window will pop up to allow the user to confirm whether to delete.

In the above examples, all text management applications are run in embedded mode. For the purpose of illustration, for text management applications run in application mode, unlike embedded mode, text management applications run in application mode can perform copy functions, but do not support text modification to prevent nested soft keyboard applications. That is, the secondary text detail page corresponding to the text management application run in application mode is shown in Figure 24. The difference from the page shown in Figure 23 is that there is no focus or cursor in this page, and text information can be viewed, and the copy function can be realized by the green key of the remote control.

In some embodiments, the application lock for the text management application can be set through the setting menu provided by the display device 200. For example, when the display device 200 displays the setting menu as shown in Figure 25, it can respond to the user input of the selection instruction for the TTM application lock option to control the display 260 to display the password verification page shown in Figure 26 A. The password of the parental lock is verified through this page. If the verification fails, it stays on the password verification page. If the password verification passes, the display 260 is controlled to display the password verification page shown in Figure 26 B, so that the user can close the application lock or set the application lock based on the prompt information in the page.

It is understandable that adding an app lock on the basis of the parental lock will increase the user's memory cost. Therefore, turn off the app lock in the settings menu. At this time, the default verified password of the password protection policy of the text management application is the parental lock password.

In some embodiments, the application lock for the text management application can be initialized through the setting menu provided by the display device 200. For example, using the setting menu shown in Figure 25, the display 260 can be controlled to display the initialization confirmation page shown in Figure 27 A in response to the user's input of the selection instruction for the TTM initialization option to prompt the user whether to initialize the application information of the text management application. In response to the user's input of the click instruction of the "Yes" control through the initialization confirmation page, the text management application is initialized, including clearing the clipboard data, all text information of the machine, the application lock password, and the default display mode. After initialization, the default display mode will become the default application history browsing, without the application lock password and without any text information.

During the initialization of the display device 200, the display 260 can be controlled to display the initialization progress page shown in Figure 27 B to prompt the user that initialization is currently in progress. After the initialization is completed, the display 260 is controlled to display the initialization completion page shown in Figure 27 C to prompt the user that initialization is completed.

In some embodiments, a one-key storage function can be implemented through a text management application. When the display 260 displays the soft keyboard control, the display device 200 can receive the fifth key value sent by the control device 100, and the fifth key value is the key value of the fifth key in the control device 100. In response to the fifth key value, the application interface of the text management application is called, and the input text entered in the target text box through the soft keyboard control is added to the text stack of the text management application through the application interface. The text stack is a storage area corresponding to the text management application for storing historical input text.

For example, the display device 200 can display a soft keyboard page as shown in Figure 28. The difference from the soft keyboard pages shown in Figures 13 and 18 is that a new prompt message "Green: Save as a note with one click" is added to the key indication window at the bottom of the page, indicating that the user presses the green key on the remote control to save the current input content.

Based on the indication of the key indication window in the soft keyboard page shown in FIG28 , the user can press the green key of the remote controller, and the remote controller can send the green key value of the green key to the display device 200. The display device 200 can store the input text entered in the target text box in the text stack of the text management application in response to the green key value.

The display device 200 can also name the input text according to a custom naming format for direct storage. For example, the naming format is "year + month + day + serial number", and the display device 200 can obtain the serial number of the current time and the text storage order for naming, such as 2405301, which means the first text stored on May 30, 2024. The upper limit of the number of newly added texts per day can also be set, such as 999, to avoid the problem of the string display being too long and overflowing the display window.

It is understandable that this method does not start the text management application, but directly calls the interface of the text management application, directly adds text to the text stack of the text management application, and adds the new text item. When the text management application is started, the text management application will actively obtain the text in the text stack and generate the text item to be displayed in the first-level text management interface, thereby completing the reading and display of data.

If the input text that needs to be stored in one click is password-type text, the password protection policy needs to be implemented. The password verification page of the application lock or parental lock needs to be popped up first. After the password verification is passed, the text can be stored.

In this embodiment, one-key saving of input text is supported. When the user wants to store the text for subsequent reuse, the user can press the shortcut key to automatically save the text, which is convenient and quick. It should be noted that the automatic saving mode of exit is not adopted in this embodiment in order to prevent the leakage of private information that the user does not want to be saved.

The following describes the text management page of the text management application from two management modes: application management mode and public management mode.

The application management mode refers to the text management of each application separately, and the public management mode refers to the text management of the entire display device 200. In the application management mode, the first-level text management page provided by the text management application includes the historical input text items corresponding to a single application. In the public management mode, the first-level text management page provided by the text management application includes the historical input text items of the entire display device.

In some embodiments, the display device 200 detects the management mode of the text management application in response to the startup instruction for starting the text management application. If the management mode is the application management mode, the primary text management page is displayed according to the application management mode. If the management mode is the public management mode, the primary text management page is displayed according to the public management mode.

In some embodiments, the management mode can be set based on a setting menu provided by the display device 200. For example, using the setting menu shown in Figure 25, the display device 200 can respond to the user's input of a selection instruction for the default file list to control the display 260 to display the setting page shown in Figure 29. The setting page includes an APP option corresponding to the application management mode and an ALL option corresponding to the public management mode. The user can select the management mode to be set by moving the focus of the control component.

In some embodiments, when the display 260 displays the primary text management page, the display device 200 may receive the eighth key value sent by the control device 100, where the eighth key value is the key value of the eighth key in the control device 100. In response to the eighth key value, the current management mode may be switched, and the primary text management page may be updated according to the switched management mode.

That is, if the current management mode is the application management mode, the application management mode is switched to the public management mode, and the first-level text management page is updated according to the public management mode. If the current management mode is the public management mode, the public management mode is switched to the application management mode, and the first-level text management page is updated according to the application management mode.

For example, following the above example, refer to the primary text management page shown in Figures 14 and 19. The "Green key: local text" in the button indication window in the page shown in Figure 14 indicates that by pressing the green key on the remote control, the application management mode can be switched to the public management mode to display the historical input text items of the display device 200. The "Green key: application text" in the button indication window in the page shown in Figure 19 indicates that by pressing the green key on the remote control, the public management mode can be switched to the application management mode to display the historical input text items of the browser.

Based on the indication of the key indication window in the primary text management page shown in FIG14 , the user can press the green key of the remote control, and the remote control can send the green key value of the green key to the display device 200. In response to the green key value, the display device 200 can switch from the application management mode to the public management mode, and update the primary text management page, so that the primary text management page presents the page shown in FIG19 .

Based on the indication of the key indication window in the primary text management page shown in FIG19 , the user can press the green key of the remote control, and the remote control can send the green key value of the green key to the display device 200. In response to the green key value, the display device 200 can switch from the public management mode to the application management mode, and update the primary text management page, so that the primary text management page presents the page shown in FIG14 .

Based on the above text management method, some embodiments of the present application further provide a display device 200, wherein the display device 200 includes a display 260 and a controller 250. The display 260 is configured to display a user interface; the controller 250 is configured to:

In response to a start instruction for starting a text management application, the text management application is started, and the text management application is used to manage the history input text of the display device.

The display 260 is controlled to display a text management page corresponding to the text management application, where the text management page includes stored historical input texts.
