[0093] Figure 3 Some embodiments of this application provide Figure 1 2 is a block diagram of the hardware configuration of the display device 200.

[0094] In some embodiments, the display device 200 may include at least one of a tuner 210, a communication device 220, a detector 230, a device interface 240, a controller 250, a display 260, an audio output device 270, a user input interface 280, a memory, and a power supply.

[0095] 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 can be provided with multiple communication devices 220 depending on the supported communication methods. The communication device 220 can enable the display device 200 to communicate with the external device or server 400 through wireless or wired connections.

[0096] In some embodiments, detector 230 is used to collect signals from the external environment or external interactions. For example, detector 230 may include a light receiver, such as a sensor for collecting ambient light intensity; or an image collector, such as a camera, for collecting external environmental scenes, user attributes, or user interaction gestures; or a sound collector, such as a microphone, for receiving external sounds.

[0097] In some embodiments, the device interface 240 is used to access an external device.

[0098] In some embodiments, the controller 250 is used to control the overall operation of the display device 200. The controller 250 may include at least one of a central processing unit (CPU), a video processor, an audio processor, a graphics processing unit (GPU), a power processor, and first to nth interfaces for input / output.

[0111] It should be noted that the above example is only a simple division of the operating system functions and does not constitute a limitation on the specific operating system form of the display device 200 in the embodiment of the present application. Depending on factors such as the function of the display device and the type of operating system, the number of levels and specific level types contained in the operating system may be expressed in other forms.

[0112] Typically, users primarily use a display device as a device with audio and video playback capabilities. To fully exploit the display device's usefulness, a first application can be configured for the display device to provide a first mode through the first application. The first application can also be referred to as an art application, an art mode application, a gallery application, a frame application, etc. The first mode can also be referred to as art mode, gallery mode, frame mode, etc. In the first mode, the display device can display artwork as a decoration for the space in which it is located. Furthermore, by simulating the artwork as a real artwork, users can browse the artwork in an immersive way. For example, a display frame can be added to the artwork, a hardware frame can be installed on the frame of the display device, or a paper-like screen can be used as a display screen.

[0113] In the embodiment of the present application, a specific description is given by taking the case where the first application is an art mode application and the first mode is an art mode as an example.

[0114] The display device 200 can enter the art mode as follows:

[0115] In some embodiments, the display device 200 may be configured to, in an off state, launch an art mode application after powering on in response to a first instruction input by a user by short pressing a power button of the control device 100 , and enter art mode after launching the art mode application.

[0116] In some embodiments, the display device 200 can be configured to: in the off state, display the system homepage in response to the user's instruction to long press the power button of the control device 100, and launch the art mode application in response to the first instruction input by the user by short pressing the power button or home button of the control device 100, and enter the art mode after launching the art mode application.

[0117] In some embodiments, the display device 200 may be configured to, in an off state, launch an art mode application after powering on in response to a first instruction input by a user through an art mode key of the control device 100 , and enter art mode after launching the art mode application.

[0118] In some embodiments, the display device 200 may be configured to enter art mode in response to a user selecting an icon for an art mode application when displaying the system homepage. The art mode application icon may be located on the system homepage or in a sidebar of the system homepage.

[0119] In some embodiments, the display device 200 may be configured to enter the art mode in response to a first instruction input by a user by short pressing a power button of the control device 100 when the display device 200 is powered on and not in the art mode.

[0120] In some embodiments, the display device 200 may be configured to enter the art mode in response to a first instruction input by a user via an art mode key of the control device 100 when the display device 200 is powered on and not in the art mode.

[0121] In some embodiments, if the user turns on a scheduled power-on and sets a power-on time, the display device 200 may be configured to: in the off state, if it is detected that the system time matches the power-on time, start the art mode application after powering on, and enter the art mode after starting the art mode application.

[0122] In some embodiments, in response to a user pressing a key, the control device 100 generates a press signal and sends it to the display device 200. In response to the user releasing the key, the control device 100 also generates a release signal and sends it to the display device 200. Accordingly, the display device 200 can determine whether the user performed a short or long press on the key by monitoring the key press and release events. For example, the display device 200 can use the dispatchKeyEvent method to capture key events. Captured key events may include a press (KeyEvent.ACTION_DOWN) event and a release (KeyEvent.ACTION_UP) event. When the display device 200 detects a key press, it detects whether it is the first press. If it is, for example, if event.getRepeatCount() == 0, it starts a timer (such as a Handler or Runnable) and uses the timer to count a predefined time, such as 500ms. If the display device 200 does not detect a release event within the predefined time, the timer triggers a long press event, thereby determining that the user has performed a long press operation on the key. If the display device 200 detects a release event within the predefined time, the timer is canceled. Since the timer does not trigger a long press event, it can be determined that the user has performed a short press operation on the key.

[0123] In other embodiments, in response to a user pressing a key, the control device 100 periodically sends a key value signal to the display device 200 until the user releases the key. The display device 200 can determine whether the user performs a short press or a long press on the key based on the number of key value signals received. If the number of key value signals received by the display device 200 is less than or equal to a preset number, it can be determined that the user performed a short press on the key. If the number of key value signals received by the display device 200 is greater than the preset number, it can be determined that the user performed a long press on the key. For example, if the preset number is 1, and the number of key value signals received by the display device 200 is 1, it can be determined that the user performed a short press on the key. If the number of key value signals received by the display device 200 is greater than 1, it can be determined that the user performed a long press on the key.

[0124] The display device 200 can be configured with a third application, which can access application data from the first application running in the background, such as artwork, image quality parameters, and carousel parameters. Thus, after entering the third application, the display device 200 is in a third mode. In the third mode, the display device 200 will display the screensaver page of the third application and, on that screensaver page, display the artwork provided by the first application, thereby displaying the artwork provided by the first application in the form of a screensaver. In the third mode, the user cannot use the related functions of the first application, i.e., cannot set the artwork, etc.

[0125] In some embodiments, the third application may also be called an art screensaver application, a gallery screensaver application, a picture frame screensaver application, etc., and the third mode may also be called an art screensaver mode, a gallery screensaver mode, a picture frame screensaver mode, etc.

[0126] In the embodiment of the present application, a specific description is given by taking the third application as an art screensaver application and the third mode as an art screensaver mode as an example.

[0127] The display device 200 can enter the art screen saver mode in the following manner:

[0128] In some embodiments, the display device 200 may be configured to enter the art screen saver mode when it is powered on and not in the art mode, if it detects that a first condition is met. The first condition may include: no user operation detected within a specified time period in a non-physical channel, or no signal input detected in the currently used physical channel.

[0129] In some embodiments, the signal channels of the display device 200 may include physical channels and non-physical channels. A physical channel refers to a channel that transmits signals via a physical medium, such as a cable, optical fiber, or satellite antenna. Physical channels may include TV channels, AV channels, and HDMI channels. A non-physical channel refers to a channel that transmits signals wirelessly without requiring a physical connection. Signals other than physical channels may be referred to as non-physical channels. Non-physical channels may include the launcher homepage, third-party applications, and the like.

[0130] After entering the art mode, the display device 200 displays a presentation page and displays artwork on the presentation page.

[0131] In some embodiments, the display page is a user interface set in the first mode. For example, the display page can be the homepage of the first application, that is, the first page displayed after entering the first mode. The display page can also be a specified user interface.

[0132] In some embodiments, when no hardware picture frame is installed, the display device 200 can add a picture frame with a three-dimensional effect to the artwork in the display page, so as to simulate a real framing effect through the added picture frame.

[0133] You can refer to Figure 5 The display page shown includes an art work 501 and a picture frame 502 for additional display.

[0134] In other embodiments, a hardware picture frame may be installed on the frame of the display device 200 to simulate a real framing effect.

[0135] You can refer to Figure 6 The display device 200 shown is equipped with a hardware picture frame 601. After entering the art mode, an art painting 602 is displayed in the display page.

[0136] In this way, in the art mode, the display device 200 can simulate the art picture into a more realistic art painting by adding a display frame to the art picture or by installing hardware decorations for simulating a frame, thereby improving the user's immersion.

[0137] In some embodiments, the art paintings provided by the art mode application can be divided into different painting categories according to scenes, picture content, etc. In this way, users can quickly find art paintings according to different painting categories.

[0138] In some embodiments, artworks within the same painting category can be further divided into different painting categories. This same painting category can be referred to as a parent painting category, and the painting categories it contains can be referred to as child painting categories. This allows users to quickly search for artworks within the same parent painting category by using different child painting categories.

[0139] In the embodiment provided in the present application, an example is given of dividing art paintings into two levels of painting classification, with the upper-level painting classification being the first-level classification and the lower-level painting classification being the second-level classification. The first-level classification may include an art gallery classification, a photo collection classification, an immersive atmosphere classification, a favorite classification, and the like. The second-level classification included in the art gallery classification may include a landscape classification, a figure classification, a modern classification, a still life classification, and the like. The second-level classification included in the photo collection classification may include a my photo classification and a photo theme classification. The second-level classification included in the immersive atmosphere classification may include an immersive atmosphere classification, and the second-level classification included in the favorite classification may include a favorite classification.

[0140] In order to facilitate users to quickly find the art paintings they want to browse according to the level and classification, the art mode application can be configured with a hierarchical browsing page. The hierarchical preview page may include a first menu and a second menu. The first menu includes the title of the first-level classification, and the second menu is used to display the title of the second-level classification included in the first-level classification that is selected or focused. The second menu also includes a preview image list, which is in a single line and includes preview images of the art paintings included in the second-level classification that is selected or focused. In some embodiments, the background of the hierarchical preview page may be transparent. In other embodiments, the background of the hierarchical preview page may be opaque or translucent. In some embodiments, the first menu and the second menu may be translucent, and the transparency may change gradually. In other embodiments, the first menu and the second menu may be opaque or transparent.

[0141] In the embodiment of the present application, an example is taken in which the background of the hierarchical preview page is transparent, the first menu and the second menu are semi-transparent, and the transparency changes gradually.

[0142] In some embodiments, when displaying a presentation page, the display device 200 may be configured to display a hierarchical browsing page on top of the presentation page in response to a user input via a confirmation key or an OK key on the control device 100. The hierarchical browsing page may display the artwork currently displayed on the presentation page below it.

[0143] You can refer to Figure 7The display effect of the hierarchical preview page is shown. The hierarchical preview page includes a first menu 701 and a second menu 702. The first menu 701 includes the titles of the first-level categories, such as Art Gallery, Photo Collection, Immersive Ambience, and Favorites. Among them, Art Gallery is in a selected state. Based on the fact that Art Gallery is in the selected state, the second menu 702 includes the titles of the second-level categories included in the Art Gallery category, such as Landscape, Figure, Modern, Still Life, and Other. Among them, Landscape is in focus. The second menu 702 also includes a preview list 703. Based on the fact that Landscape is in focus, the preview list 703 includes the preview images of the art works in the Landscape category. For example, the preview images of Landscape 14, Landscape 15, Landscape 16, Landscape 17, and Landscape 18.

[0144] In this embodiment of the present application, for the sake of illustration, the corresponding art works are represented in the form of "second-level category + order of the picture in the second-level category". For example, Landscape 16 represents the 16th art work in the Landscape category.

[0145] The background of the hierarchical preview page is in a transparent state. For details, please refer to Figure 7 The background 704 is in a transparent state. Therefore, the art works currently displayed in the display page, such as the three geometric figures, can be displayed through the background 704.

[0146] In some embodiments, based on the hierarchical preview page, the user can select the first-level category and the second-level category that he or she wants to preview, to browse the preview images of the corresponding art works in the preview list. Moreover, the user can exit the hierarchical preview page by selecting a preview image, and quickly switch the art work displayed in the display page to the art work corresponding to the selected preview image.

[0147] In some embodiments, in order to facilitate the user to preview more preview images at a time and improve the efficiency of finding art works, the art mode application can also be configured with a global preview page. The global preview page can include a third menu and a global preview list. The third menu includes the titles of the second-level categories included in the target first-level category, and the title of the target second-level category is in focus. The target first-level category is the first-level category to which the art work currently displayed in the display page belongs, and the target second-level category is the second-level category to which the art work corresponding to the preview image currently included in the preview list belongs. The global preview list is in the form of a grid and includes the preview images of the art works in the target second-level category. In this way, through the global preview page, the user can browse the preview images of the art works in each second-level category in the target first-level category at a time.

[0148] In some embodiments, when a preview image in the preview image list gains focus, the display device 200 may be configured to display a global preview page on an upper layer of the hierarchical preview pages in response to a downward instruction input by the user using the down key of the control device 100 .

[0149] Can Figure 7 The hierarchical preview page shown in FIG. 1 may be displayed on the upper layer of the hierarchical preview page in response to the downward instruction of the user. Figure 8 The global preview page shown in the figure includes a third menu 801. Third menu 801 includes titles of the art gallery's secondary categories, such as Landscape, Figures, Modern, Still Life, and Other. Landscape is the focus. The global preview page also includes a global preview image list 802, which includes preview images of all artworks in the Landscape category. For example, for all artworks in the Landscape category, Landscapes 1 to 18 are included in the global preview image list 802.

[0150] In some embodiments, users can select a desired secondary category under the target primary category on the global preview page to browse preview images of the corresponding artwork in the global preview list. Furthermore, users can exit the global preview page and the hierarchical preview page by selecting a preview image, and quickly switch the artwork displayed on the display page to the artwork corresponding to the selected preview image.

[0151] In some embodiments, the art mode application can be configured with an application settings menu. The application settings menu is different from the system settings menu. It is a settings menu within the art mode application. The application settings menu includes menu items for setting parameters related to art paintings. The parameters set based on the application settings menu will not affect the overall parameters of the display device 200. In some embodiments, the application settings menu can be a shortcut menu. When displaying the display page, the display device 200 can open the application settings menu in response to the control instruction input by the user based on the first button of the control device 100. In some embodiments, the first button can be a menu button, a color button, etc. In the embodiment of the present application, the first button is taken as an example for specific description.

[0152] The application settings menu is displayed on the upper layer of the display page, you can refer to Figure 9 The application setting menu 901 is shown, and the application setting menu 901 is displayed on the upper layer of the display page. In this way, when the user uses the application setting menu, he can browse the art paintings in the display page at the same time and observe the setting effects after setting through the application setting menu.

[0153] In some embodiments, the art mode application can be configured with an art mode settings page. The art mode settings page is a settings page for the art mode application. This settings page is different from the system settings page and is dedicated to setting parameters related to art paintings. The parameters set based on the art mode settings page will not affect the overall parameters of the display device 200. It can be considered that the art mode settings page is the page corresponding to the application settings menu. The art mode settings page can display all the setting items for setting the relevant parameters of art paintings at one time. You can refer to Figure 10 The Art Mode settings page shown in the figure. This way, based on the Art Mode settings page, users can set various parameters more centrally.

[0154] In some embodiments, an entry to the art mode settings page may be configured in the application settings menu, such as Figure 9 As shown, the application setting menu 901 includes an entry to the art mode setting page, such as “art mode setting.” In this way, the user can enter the art mode setting page through the application setting menu.

[0155] In some embodiments, the immersive atmosphere classification may include dynamic artworks with audio, that is, the immersive atmosphere classification includes artworks as videos. In this way, when the display device 200 displays the artworks under the immersive atmosphere classification, it will play the corresponding audio at the same time to create a sense of atmosphere for the user. However, the audio included in the artworks under the immersive atmosphere classification may not be the music that the user likes, which will result in the inability to create the atmosphere that the user likes. Moreover, for artworks under other categories, these artworks are all pictures, so the display device 200 will not play audio when displaying these artworks. Then, when the user browses these artworks, he will lack a sense of atmosphere.

[0156] In order to solve the above problems, the art mode application is configured with an application Bluetooth music function. In this way, in art mode, users can use the application Bluetooth music function to connect to a Bluetooth device at any time, and send their favorite audio to the display device 200 through the Bluetooth device to play the audio through the display device 200, thereby creating an atmosphere they like.

[0157] In some embodiments, reference may be made to Figure 4 In the operating system shown, the application layer of the operating system is configured with modules related to the first application, such as a Bluetooth switch module, a connection device management module, a registration monitoring module, an operation guidance module, and a playback control module. The framework layer is configured with a Bluetooth music receiving module and a music playback control module. The core layer is configured with a Bluetooth communication module and a Bluetooth driver.

[0158] The Bluetooth switch module is configured to display different Bluetooth switches to the user and interact with the user to turn on or turn off the switches.

[0159] The connection device management module is configured to manage the connected Bluetooth devices and generate and display a corresponding device list.

[0160] The registration monitoring module is configured to monitor the connection state of the Bluetooth device, the audio playing state of the Bluetooth device, and the like.

[0161] The operation guide module is configured to display operation guides for pairing with the Bluetooth device and the like.

[0162] The playing control module is configured to control the audio playing of the whole machine and the like.

[0163] The Bluetooth music receiving module, as the Bluetooth receiving end of the display device 200, is configured to receive the Bluetooth music signal from the Bluetooth device.

[0164] The music playing control module is configured to control the playing, pausing, volume adjustment, and the like of the music according to the control instruction of the application layer, call the audio service and the media player service of the system, and the like.

[0165] The driver layer is located at the hardware layer of the television device and is responsible for communicating with the Bluetooth hardware module and controlling the audio output device. The main functions include: communicating with the Bluetooth hardware module, receiving the Bluetooth music signal from other devices, and the like.

[0166] As for the Bluetooth device, if it is distinguished according to the receiving and sending of the audio data, it can be divided into an audio source device and an audio receiving device. The audio source device is a Bluetooth device configured to provide (send) audio data to the audio receiving device. The audio receiving device is a Bluetooth device configured to receive the audio data sent by the audio source device. Thus, the audio receiving device can be used as an audio playing device to play the audio data provided by the audio source device. The same Bluetooth device can switch the Bluetooth mode according to different use requirements. The Bluetooth mode includes a source mode and a sink mode. If the Bluetooth device is in the source mode, the Bluetooth device currently serves as the audio source device. If the Bluetooth device is in the sink mode, the Bluetooth device currently serves as the audio receiving device.

[0167] In some embodiments, the display device 200 can be configured to use the source mode as the default, that is, as the audio source device.

[0168] In some embodiments, the display device 200 can be configured with a system Bluetooth function. The first Bluetooth switch configured to control the turning on and turning off of the system Bluetooth function can be configured in the system setting menu, the quick setting panel, the status bar, the shortcut menu, and the like.

[0169] Take the first Bluetooth switch configured in the system settings menu as an example, you can refer to Figure 11 The system setting menu shown may include a first Bluetooth switch 1101. When the first Bluetooth switch is in an on state, the system Bluetooth function is turned on, and when the first Bluetooth switch is in an off state, the system Bluetooth function is turned off.

[0170] When the system Bluetooth function is turned on, the display device 200 can be paired with other Bluetooth devices. When the system Bluetooth function is turned off, the display device 200 cannot be paired with other Bluetooth devices.

[0171] In some embodiments, when the Bluetooth function of the system is turned on and off through the first Bluetooth switch, the display device 200 always uses the source mode, that is, the display device 200 always acts as an audio source device to provide audio data to the paired Bluetooth device to play audio through the paired Bluetooth device.

[0172] For example, when the system Bluetooth function is turned on by the first Bluetooth switch, the display device 200 will be paired with other Bluetooth devices as an audio source device, such as a Bluetooth speaker. After pairing with the Bluetooth speaker, the display device 200 can send audio data to the Bluetooth speaker to play audio through the Bluetooth speaker.

[0173] In some embodiments, a monitoring module for system controls may be configured at the application layer, and the monitoring module may monitor the status changes of various system controls. When the first Bluetooth switch is in the off state, if the user instructs to turn on the first Bluetooth switch, the monitoring module may monitor the turning on of the first Bluetooth switch, and after monitoring the turning on of the first Bluetooth switch, the system Bluetooth function may be turned on by calling the system Bluetooth service. When the first Bluetooth switch is in the on state, if the user instructs to turn off the first Bluetooth switch, the monitoring module may monitor the turning off of the first Bluetooth switch, and after monitoring the turning off of the first Bluetooth switch, the system Bluetooth function may be turned off by calling the system Bluetooth service. In this way, the system Bluetooth function can be turned on and off by controlling the first Bluetooth switch.

[0174] In some embodiments, the default state of the first Bluetooth switch, that is, the default state of the system Bluetooth function, refers to the state of the first Bluetooth switch in the display device 200 when the display device 200 is not using the application Bluetooth music function. The default state of the first Bluetooth switch can be an on state or an off state. For example, in order to avoid power consumption caused by the system Bluetooth function being turned on all the time, and to avoid frequent pairing requests from other Bluetooth devices caused by the system Bluetooth function being turned on all the time, the default state of the first Bluetooth switch can be set to an off state. For another example, in order to facilitate pairing of the display device 200 with other Bluetooth devices, the default state of the first Bluetooth switch can be set to an on state.

[0175] In some embodiments, the display device 200 may also be configured with a second Bluetooth switch, which is a switch for the device visibility function. Figure 11 The system setting menu shown may include a second Bluetooth switch 1102. When the second Bluetooth switch is on, the device visibility function is enabled, that is, if the system Bluetooth function is enabled, the display device 200 can be discovered by other Bluetooth devices. When the second Bluetooth switch is off, the device visibility function is disabled, that is, if the system Bluetooth function is enabled, the display device 200 cannot be discovered by other Bluetooth devices.

[0176] In some embodiments, the default state of the second Bluetooth switch, that is, the default state of the device visibility function, refers to the state of the second Bluetooth switch in the display device 200 when the display device 200 is not using the application Bluetooth music function. The default state of the second Bluetooth switch can be on or off. For example, in order to avoid frequently receiving pairing requests from other Bluetooth devices when the system Bluetooth function is always on, the default state of the second Bluetooth switch can be set to off. For another example, in order to facilitate pairing of the display device 200 with other Bluetooth devices, the default state of the second Bluetooth switch can be set to on.

[0177] In some embodiments, the monitoring module of the system control can monitor the state changes of the second Bluetooth switch and control the turning on and off of the visibility function by calling the device visibility service, thereby realizing the control of turning on and off the visibility function through the second Bluetooth switch. This process can be referred to the process of turning on and off the system Bluetooth function through the first Bluetooth switch, and is not repeated here.

[0178] In some embodiments, the display device 200 may also be configured with a third Bluetooth switch, which is a switch for a device shielding function. When the third Bluetooth switch is on, the device shielding function is enabled, so that when the system Bluetooth function is enabled, a connection is not established with a specified Bluetooth device. When the third Bluetooth switch is off, the device shielding function is disabled, so that when the system Bluetooth function is enabled, a connection can be established with a specified Bluetooth device. The specified Bluetooth device can be a user-specified Bluetooth device, a Bluetooth device other than a user-specified Bluetooth device that can be connected, or a Bluetooth device other than the currently connected Bluetooth device.

[0179] In some embodiments, the default state of the third Bluetooth switch, that is, the default state of the device shielding function, refers to the state of the third Bluetooth switch in the display device 200 when the display device 200 is not using the application Bluetooth music function. The default state of the third Bluetooth switch can be an on state or an off state. For example, in order to avoid frequently receiving pairing requests and connection requests from these designated Bluetooth devices when the system Bluetooth function is always on, and to avoid these designated Bluetooth devices establishing a connection with the display device 200 and sending audio data to the display device 200, affecting the current playback of the display device 200, etc., the default state of the third Bluetooth switch can be set to an on state. For another example, in order to show the user the Bluetooth devices that can be paired, the default state of the third Bluetooth switch can be set to an off state.

[0180] In some embodiments, a Bluetooth device whitelist can be used to manage Bluetooth devices that can establish a connection with the display device 200. Bluetooth devices not on the whitelist are designated Bluetooth devices, that is, Bluetooth devices that cannot establish a connection with the display device 200 after the device blocking function is enabled. The Bluetooth devices in the whitelist can be dynamically adjusted according to user settings.

[0181] In some embodiments, designated Bluetooth devices can be managed through a blacklist of Bluetooth devices, that is, the Bluetooth devices on the blacklist are designated Bluetooth devices, that is, Bluetooth devices that cannot establish a connection with the display device 200 after the device shielding function is turned on. The Bluetooth devices in the blacklist can be dynamically adjusted according to user settings.

[0182] In some embodiments, a whitelist or blacklist of Bluetooth devices can be written into a configuration file. After the monitoring module of the system control monitors that the first Bluetooth switch is turned on, if a pairing request or connection request from another Bluetooth device is received, the whitelist or blacklist in the configuration file is read to determine whether the Bluetooth device is a designated Bluetooth device based on the whitelist or blacklist. If the Bluetooth device is a designated Bluetooth device, the device shielding service is called to reject or not respond to the request of the Bluetooth device. If the Bluetooth device is not a designated Bluetooth device, the device shielding service is not called, and the request of the Bluetooth device is responded to normally.

[0183] In some embodiments, the default states of the first Bluetooth switch, the second Bluetooth switch, and the third Bluetooth switch are independent of each other.

[0184] In Art Mode, to expand the audio resources that can be played by the display device 200, other Bluetooth devices can be used to provide richer audio data. In this case, the display device 200 needs to be used as an audio receiving device to receive the audio data provided by other Bluetooth devices. In other words, the display device 200 needs to be switched to sink mode. Accordingly, the application Bluetooth music function provided by the Art Mode application is a Bluetooth function that pairs the display device 200 as an audio receiving device with other Bluetooth devices.

[0185] In some embodiments, in the art mode, the display device 200 may Figure 12 The process shown plays audio from a Bluetooth device. The specific steps are as follows:

[0186] S1201: In the art mode, in response to a user's operation of turning on the Bluetooth music function of the application, switching to the audio receiving mode and displaying an operation guide page. When the default state of the first Bluetooth switch is off, turning on the first Bluetooth switch.

[0187] In some embodiments, the Art Mode application can configure the switch of the application Bluetooth music function in the application settings menu. Figure 9 The application settings menu 901 shown includes a switch for applying a Bluetooth music function, such as BT Music. Accordingly, a user can activate the Bluetooth music function by, when the display device 200 is displaying a presentation page, inputting a menu command using the menu key of the control device 100 to control the display device 200 to open the application settings menu, and then activating the Bluetooth music function by selecting the switch for applying the Bluetooth music function in the application settings menu.

[0188] In other embodiments, the art mode application can configure the switch of the application Bluetooth music function in the art mode settings page. Figure 10 The Art Mode settings page shown includes a switch for applying a Bluetooth music function, such as BT Music. Accordingly, a user can enable the Bluetooth Music function by, while display device 200 is displaying the presentation page, inputting a menu command using the menu key of control device 100 to control display device 200 to open the application settings menu, and then selecting the Art Mode setting item in the application settings menu to open the Art Mode settings page. Selecting the switch for applying the Bluetooth Music function on the Art Mode settings page enables the Bluetooth Music function.

[0189] Since the application Bluetooth music function is a Bluetooth function that pairs the display device 200 as an audio receiving device with other Bluetooth devices, when the display device 200 turns on the application Bluetooth music function, the display device 200 switches from source mode to sink mode to pair with other Bluetooth devices as an audio receiving device.

[0190] In some embodiments, in order to ensure the availability of the application Bluetooth music function, when using the application Bluetooth music function, if the system Bluetooth function of the display device 200 is turned off, the system Bluetooth function can be forcibly turned on so that the display device 200 can use the Bluetooth function to pair with other Bluetooth devices.

[0191] In some embodiments, to avoid affecting the overall performance of the display device 200, if the application Bluetooth music function is not used, such as exiting the art mode, or disconnecting from other Bluetooth devices, the system Bluetooth function is restored to its default state. If the system Bluetooth function is enabled by default, the system Bluetooth function is kept enabled, i.e., the first Bluetooth switch is kept enabled. If the system Bluetooth function is disabled by default, the system Bluetooth function is disabled again, i.e., the first Bluetooth switch is switched back to the disabled state.

[0192] When the display device 200 uses the Bluetooth music function, the first Bluetooth switch is turned on to enable the system Bluetooth function. The following embodiments can be referred to for implementation:

[0193] In some embodiments, the display device 200 can call the first Bluetooth switch by the first application to achieve a linkage effect between the application Bluetooth music function and the system Bluetooth function.

[0194] You can refer to Figure 4 In the operating system shown, the user interacts with the first application through the Bluetooth switch module, such as turning on the application Bluetooth music function. The Bluetooth switch module will call the system Bluetooth service to turn on the system Bluetooth function. The system Bluetooth service will record the default state of the first Bluetooth switch, such as the off state. When the activity manager detects that the operation guide page is closed or the pairing page is closed, if the registration monitoring module of the application detects that it is not paired with the Bluetooth device or a connection is established, the registration monitoring module of the application can send a first notification to the Bluetooth switch module, or after the registration monitoring module of the application detects that it is disconnected from the Bluetooth device, it sends a first notification to the Bluetooth switch module, or when the activity manager detects exiting the first application, it can send a first notification to the Bluetooth switch module. Based on the first notification, the Bluetooth switch module will call the system Bluetooth service to restore the default state of the first Bluetooth switch, such as turning off the first Bluetooth switch to turn off the system Bluetooth service.

[0195] In other embodiments, the display device 200 may monitor the usage status of the first application through the system's registered monitoring module, and call the first Bluetooth switch to achieve a linkage effect between the application's Bluetooth music function and the system's Bluetooth function.

[0196] You can refer to Figure 4 In the illustrated operating system, in the application layer, the modules related to the first application may also include a configuration file containing the first application's configuration information. For example, if the first application requires the system Bluetooth function, the system Bluetooth function must be enabled after the first application is launched. A system registration monitoring module is also configured in the application layer. During the startup process of the display device 200, the system registration monitoring module scans the configuration files of each application. Upon detecting the configuration file of the first application, the system's configuration information is read and, based on this configuration information, the first application is registered with an application list. The application list includes applications that require the system Bluetooth function, meaning that the system Bluetooth function must be enabled after these applications are launched. The system registration monitoring module monitors the launch of each activity and determines the application to launch based on the corresponding package name of the activity. After detecting the first application's activity, the system registration monitoring module determines to launch the first application. The system registration monitoring module determines whether the first application is in the application list and, upon determining that the first application is in the application list, calls the system Bluetooth service to turn on the first Bluetooth switch, thereby activating the system Bluetooth service. In some embodiments, the configuration information of the first application may include a page with an application settings menu. In this way, when the system's registration monitoring module registers the first application to the application list, it can accurately register it to the page with the application settings menu. That is, when the first application is entered and the application settings menu is opened, the system Bluetooth service is enabled. After monitoring the activity on the page with the application settings menu, the system's registration monitoring module can call the system Bluetooth service to turn on the first Bluetooth switch, thereby enabling the system Bluetooth service.

[0197] When the activity manager detects that the operation guide page is closed or the pairing page is closed, a message can be sent to the system's registration monitoring module. After receiving the message, if the system's registration monitoring module detects that it has not paired with the Bluetooth device or established a connection, the system's registration monitoring module can shut down the system Bluetooth service to turn off the first Bluetooth switch and the system's Bluetooth function. Alternatively, after the system's registration monitoring module detects that the connection with the Bluetooth device is disconnected, the system's Bluetooth service can be shut down to turn off the first Bluetooth switch and the system's Bluetooth function. Alternatively, when the activity manager detects that the first application is exited, a message can be sent to the system's registration monitoring module. After receiving the message, the system's registration monitoring module can shut down the system Bluetooth service to turn off the first Bluetooth switch and the system's Bluetooth function.

[0198] In some embodiments, if the display device 200 is configured with a second Bluetooth switch, the display device 200 responds to the user's operation of turning on the application Bluetooth music function, and when the second Bluetooth switch is in the off state, the second Bluetooth switch is forced to turn on to turn on the device visibility function, so that the display device 200 can be discovered by other Bluetooth devices when the system Bluetooth function is turned on, thereby ensuring that the application Bluetooth music function is available. Figure 11 A second Bluetooth switch 1102 is shown.

[0199] Accordingly, to avoid affecting the overall performance of the display device 200, when the Bluetooth music function is not used, such as when exiting the art mode or disconnecting from other Bluetooth devices, the device visibility function is restored to its default state. If the default state of the device visibility function is on, the device visibility function is kept on, i.e., the second Bluetooth switch is kept on. If the default state of the device visibility function is off, the device visibility function is turned off again, i.e., the second Bluetooth switch is switched off.

[0200] Among them, when the display device 200 uses the Bluetooth music function, the second Bluetooth switch is turned on to turn on the device visibility function. The implementation process can refer to the process of turning on the first Bluetooth switch, which is not repeated here.

[0201] In some embodiments, if the display device 200 is configured with a third Bluetooth switch, the display device 200 responds to the user's operation of turning on the application Bluetooth music function. When the third Bluetooth switch is in the off state, the display device 200 forces the third Bluetooth switch to be turned on to turn on the device shielding function, so that the display device 200 cannot be discovered by designated Bluetooth devices when the system Bluetooth function is turned on, so as to avoid being interfered with by these Bluetooth devices.

[0202] Accordingly, to avoid affecting the overall performance of the display device 200, if the Bluetooth music function is not used, such as exiting the art mode, or disconnecting from other Bluetooth devices, the device shielding function is restored to its default state. If the default state of the device shielding function is on, the device shielding function is kept on, i.e., the third Bluetooth switch is kept on. If the default state of the device shielding function is off, the device shielding function is turned off again, i.e., the third Bluetooth switch is switched off.

[0203] Among them, when the display device 200 uses the application Bluetooth music function, turning on the third Bluetooth switch to turn on the device shielding function can refer to the process of turning on the first Bluetooth switch, which is not repeated here. Among them, the configuration information of the first application can include a whitelist or blacklist of Bluetooth devices.

[0204] After the display device 200 switches to the sink mode and turns on the system Bluetooth function, it can be paired with other Bluetooth devices.

[0205] In some embodiments, after switching to the sink mode, the display device 200 sends a pairing broadcast to the surroundings. The pairing broadcast may include the device class (Class of Device), the service's universally unique identifier (UUID), the device name, etc.

[0206] The device category is the current Bluetooth device type of the display device 200. For example, if the device is currently in sink mode, the device type is an audio receiving device.

[0207] The UUID of the service included in the pairing broadcast is used to uniquely identify the service supported by the display device 200. For Bluetooth devices that support audio streaming transmission function, the supported services include Advanced Audio Distribution Profile (A2DP) service. Based on different Bluetooth modes, the supported A2DP services are also different. Among them, in sink mode, the Bluetooth device supports A2DP receiving service. In source mode, the Bluetooth device supports A2DP sending service. Accordingly, the display device 200 will register the UUID of the currently supported service. After the display device 200 switches to sink mode, it supports A2DP receiving service. Therefore, the display device 200 will register the UUID of the A2DP receiving service, for example, 0000110b-0000-1000-8000-00805f9b34fb.

[0208] The device name may be a default name of the display device 200 or a user-defined name, which is displayed in a search result list of the peer device to represent the display device 200 .

[0209] In some embodiments, the display device 200 may display an operation guidance page, which includes first guidance information for performing a Bluetooth connection operation with the display device 200. The first guidance information may include the device name of the display device 200 to accurately indicate the Bluetooth device to be paired, so that the user can quickly and accurately connect to the display device 200.

[0210] You can refer to Figure 13 The operation guide page shown may include a first guide message. If the device name of the display device 200 is "Master Bedroom TV", the first guide message may be "Turn on the Bluetooth switch, select Master Bedroom TV to pair and connect".

[0211] In some embodiments, after the display device 200 turns on the system Bluetooth function, the status of the system Bluetooth function of the display device 200 is also displayed on the operation guide page to prompt the user of the Bluetooth status of the display device 200, so that the user can check the reasons for different situations when the display device 200 is connected to other Bluetooth devices. Figure 13 The operation guide page shown in the figure displays the current status of the system Bluetooth function in the upper right corner, such as whether the Bluetooth function is available. It may also include an icon for the Bluetooth function.

[0212] For example, a user wants to use a first Bluetooth device to provide audio data to the display device 200. The first Bluetooth device can be a smart phone, tablet computer, computer, smart TV, etc. The user can perform a Bluetooth connection operation with the display device 200 on the first Bluetooth device according to the first guidance information in the operation guidance page.

[0213] In some embodiments, after the Bluetooth function is enabled, the first Bluetooth device is in source mode and can scan for surrounding Bluetooth devices.

[0214] The first Bluetooth device serves as an audio source device. After turning on the Bluetooth function, the pairing broadcast sent out may include the device type, service UUID, device name, etc.

[0215] The device type of the first Bluetooth device is an audio source device. In source mode, the display device 200 supports the A2DP send service and registers the UUID of the A2DP send service, such as 0000110a-0000-1000-8000-00805f9b34fb. The device name can be the default name of the first Bluetooth device or a user-defined name.

[0216] When the display device 200 sends a pairing broadcast, the first Bluetooth device can scan the display device 200 .

[0217] After scanning the display device 200, the first Bluetooth device can display a search result list. The first Bluetooth device can display the device name in the pairing broadcast sent by the display device 200 in the search result list. For example, if the device name of the display device 200 is the master bedroom TV, you can refer to Figure 14 The search result list shown includes a result item for "master bedroom television".

[0218] The user determines, based on the first guidance information on the operation guidance page, that the device to be connected is the master bedroom TV, then finds the result item for the master bedroom TV in the search result list, selects the result item, and pairs it with the display device 200. In response to the user's instruction to select the result item, the first Bluetooth device sends a pairing request to the corresponding display device 200, requesting to establish a Bluetooth connection.

[0219] S1202: Display a pairing page according to the pairing request of the first Bluetooth device.

[0220] When the display device 200 is paired with the first Bluetooth device for the first time, a pairing page is displayed, which includes inquiry information for asking the user whether to pair with the first Bluetooth device. In this way, the data security of the display device 200 can be further guaranteed.

[0221] You can refer to Figure 15 The pairing page shown may include a prompt message to inform the user of the device name of the first Bluetooth device currently being paired, such as "my phone." In some embodiments, during the pairing process with the first Bluetooth device, the display device 200 may also send a pairing password to the first Bluetooth device to further ensure the accuracy and security of the pairing. The pairing page also includes a Pair button and a Cancel button. If the user agrees to pair with the first Bluetooth device, the user may select the Pair button. If the user disagrees with the first Bluetooth device, the user may select the Cancel button.

[0222] S1203: In response to the user's instruction to agree to pairing, pair with the first Bluetooth device, and display a prompt page after pairing with the first Bluetooth device is successful.

[0223] If the user selects the pairing button and inputs an instruction to agree to pairing, the display device 200 is paired with the first Bluetooth device and a connection is established.

[0224] In some embodiments, after successfully pairing with the display device 200, the first Bluetooth device can use the Service Discovery Protocol (SDP) to query the services supported by the display device 200 to further confirm whether the display device 200 is in sink mode. For example, the first Bluetooth device can confirm whether the display device 200 is in sink mode by querying whether the display device 200 has registered the UUID of the A2DP sink service. After recognizing that the display device 200 has registered the UUID of the A2DP sink service, it can be confirmed that the display device 200 is in sink mode.

[0225] In some embodiments, after successfully pairing with the first Bluetooth device, the display device 200 saves the pairing information of the first Bluetooth device so that when the Bluetooth music function of the application is used again, it can quickly connect to the first Bluetooth device based on the stored pairing information of the first Bluetooth device.

[0226] In some embodiments, in Art Mode, if the user turns on the Bluetooth music function again, the display device 200 may display an operation guide page. This process may refer to step S1201 and will not be described in detail here. The display device 200 may also display a list of paired devices. In some embodiments, the display device 200 may display a list of paired devices within the operation guide page. In other embodiments, the display device 200 may be configured to automatically exit the operation guide page and display a list of paired devices after a second duration.

[0227] In some embodiments, the display device 200 can display a paired device list based on the stored pairing information of the first Bluetooth device, and the paired device list includes an item of the first Bluetooth device. If the display device 200 has established a Bluetooth connection with other Bluetooth devices based on the application of the Bluetooth music function, the paired device list also includes items of these Bluetooth devices. Figure 16 In the paired device list shown, if the device name of the first Bluetooth device is "myphone," the paired device list may include an entry for "myphone." If display device 200 has established a Bluetooth connection with another Bluetooth device based on the Bluetooth music function, and the device name of the other Bluetooth device is "living room TV," the paired device list may also include an entry for "living room TV."

[0228] The user can select the target Bluetooth device to be connected this time based on the paired device list on the display device 200. For example, if the user wants to use the first Bluetooth device, the user can select the item of the first Bluetooth device and input a connection instruction. In response to the connection instruction, the display device 200 searches for the first Bluetooth device and establishes a connection with the first Bluetooth device after finding the first Bluetooth device.

[0229] In some embodiments, after successfully pairing with the display device 200 , the first Bluetooth device saves the pairing information of the display device 200 so as to quickly establish a connection with the display device 200 next time.

[0230] In some embodiments, after the first Bluetooth device turns on the Bluetooth function, it can display a paired device list according to the stored paired information, and the paired device list includes an item of the display device 200. Figure 17In the paired device list shown, if the device name of the display device 200 is "Master Bedroom TV," the paired device list may include an item for "Master Bedroom TV." If the first Bluetooth device has also established a connection with another Bluetooth device, such as a Bluetooth headset, the paired device list may also include an item for the Bluetooth headset.

[0231] If the user wants to connect to the display device 200, he can select the item of the master bedroom TV and input a connection instruction. In response to the connection instruction, the first Bluetooth device searches for the display device 200 and establishes a connection with the display device 200 after searching for the display device 200.

[0232] In some embodiments, when the display device 200 is not paired with the first Bluetooth device for the first time, in response to a pairing request from the first Bluetooth device, the display device 200 directly pairs with the first Bluetooth device and establishes a connection without displaying a pairing page.

[0233] In some embodiments, the display device 200 displays a prompt page after successfully pairing with the first Bluetooth device, so as to prompt the user that the first Bluetooth device has been connected. The prompt page may include second guidance information, and the second guidance information is used to guide the user to use the first Bluetooth device to play audio. Figure 18 The prompt page shown may include a second guidance message, such as “Please open the mobile app and play your favorite songs.”

[0234] In some embodiments, the display device 200 may be configured to automatically exit the prompt page after a first duration and display the presentation page of the art mode application. For example, if the first duration is 10 seconds, the display device 200 may automatically exit the prompt page after displaying the prompt page for 10 seconds.

[0235] In some embodiments, the display device 200 may be configured to, in response to a user's back command, exit the prompt page and display the presentation page of the art mode application. For example, the user may input a back command by using the back key of the control device 100, and the display device 200 may exit the prompt page in response to the back command.

[0236] In some embodiments, the display device 200 may display a prompt message in the prompt page, which is used to prompt the user to automatically jump to the display page after the first time period, and the user can exit the prompt page by pressing the return key, such as Figure 18 shown.

[0237] S1204: After receiving the first audio sent by the first Bluetooth device, play the first audio.

[0238] In some embodiments, if a user uses a first Bluetooth device to play a first audio, the first Bluetooth device may send a play notification and the first audio to the display device 200. The display device 200 may determine that the first Bluetooth device is in the audio playback state based on the play notification. After determining that the first Bluetooth device is in the audio playback state, the display device 200 exits the prompt page and displays the display page of the art mode application.

[0239] After receiving the first audio, the display device 200 plays the first audio and displays a display page of the art mode application, thereby creating an atmosphere that the user likes.

[0240] In some embodiments, when the display device 200 determines that the first Bluetooth device is in the audio playback state, the device playback information can be displayed on the display page. The device playback information can include the device name and device icon of the first Bluetooth device. The device icon is used to identify the device type of the first Bluetooth device. Figure 18 The display page shown, when the display device 200 determines that the first Bluetooth device is in the audio playback state, if the first Bluetooth device is a mobile phone and the device name is my phone, an icon identifying the mobile phone and my phone can be displayed in the upper right corner of the display page.

[0241] In some embodiments, the display device 200 hides the device playback information after a preset time period, so as to avoid affecting the display effect of the artwork.

[0242] In some embodiments, if the display device 200 is currently playing the second audio, when it is recognized that the first Bluetooth device is in the audio playing state, in order to avoid the playback of the second audio affecting the playback quality of the first audio, the second audio can be muted.

[0243] In some embodiments, when the display device 200 recognizes that the first Bluetooth device is in audio playback mode, it can control the first player to be muted, and the first player is used to play the second audio. In this way, the volume of the second audio is 0, which is muted and does not affect the playback quality of the first audio.

[0244] In some embodiments, when the display device 200 recognizes that the first Bluetooth device is in an audio playback state, it can control the pause or shutdown of the audio channel playing the second audio to pause or exit the playback of the second audio, thereby achieving the effect of muting the second audio. In addition, the display device 200 opens the audio channel of the first audio to play the first audio.

[0245] In some embodiments, the display device 200 can establish connections with a first Bluetooth device and a second Bluetooth device at the same time, and the number of the second Bluetooth device is at least one.

[0246] In some embodiments, the display device 200 can be discovered by other Bluetooth devices after the system Bluetooth function and the device visibility function are turned on. The display device 200 can respond to the pairing request of the second Bluetooth device and pair with the second Bluetooth device and establish a connection when the user agrees to pair.

[0247] In some embodiments, if the second Bluetooth device is a Bluetooth device that has been paired with the display device 200, the display device 200 can display a list of paired devices in response to the user opening the application Bluetooth music function, and establish a connection with the second Bluetooth device in response to the user's instruction to select the item of the second Bluetooth device from it.

[0248] In some embodiments, when the display device 200 is connected to multiple Bluetooth devices at the same time, one Bluetooth device can be selected to provide audio. Figure 19 The process shown is to switch Bluetooth devices. The specific steps are as follows:

[0249] S1901: In response to a user's control instruction, display a list of connected devices.

[0250] In some embodiments, the art mode application can be configured to display a list button on the display page when using the Bluetooth music function of the application. The user can enter a control instruction by selecting the list button, and the display device 200 responds to the control instruction by displaying a list of connected devices.

[0251] When the first Bluetooth device and the second Bluetooth device are currently connected at the same time, the connected device list includes items of the first Bluetooth device and the second Bluetooth device.

[0252] You can refer to Figure 20 In the display page shown, display device 200 displays a connected device list 2002 in response to a user selecting list button 2001. If the device name of the first Bluetooth device is "my phone" and the device name of the second Bluetooth device is "living room TV," connected device list 2002 may include items for "my phone" and "living room TV."

[0253] S1902: In response to an instruction by the user to select an item of the second Bluetooth device, stop receiving the first audio from the first Bluetooth device and start receiving the audio sent by the second Bluetooth device.

[0254] The display device 200 is currently playing the first audio provided by the first Bluetooth device. If the user wants to use the second Bluetooth device, that is, wants to play the audio provided by the second Bluetooth device, the item of the second Bluetooth device can be selected in the list of connected devices. In response to the instruction, the display device 200 switches the audio source device to the second Bluetooth device, that is, maintains the connection with the first Bluetooth device, but no longer receives the first audio sent by the first Bluetooth device, and starts receiving the third audio sent by the second Bluetooth device. Among them, the display device 200 can also send a first notification to the first Bluetooth device to notify the first Bluetooth device to terminate receiving audio. The first Bluetooth device can pause playing the first audio according to the first notification. The display device 200 can also send a second notification to the second Bluetooth device to notify the second Bluetooth device that it can receive the audio sent by it.

[0255] S1903: After receiving the third audio sent by the second Bluetooth device, play the third audio.

[0256] When the display device 200 switches the audio source device to the second Bluetooth device, the second Bluetooth device can be in an audio playback state, an audio pause state, or an audio stop state. If the user opens a music application on the second Bluetooth device and plays a third audio, the third audio can be sent to the display device 200, and the display device 200 plays the third audio after receiving the third audio.

[0257] In some embodiments, after the display device 200 recognizes that the second Bluetooth device is in an audio playback state, it can display device playback information on the display page. The device playback information can include the device name and device icon of the second Bluetooth device, and the device icon is used to identify the device type of the second Bluetooth device. Furthermore, after a preset time period, the device playback information is hidden. The process of displaying and hiding the device playback information can refer to the process of displaying and hiding the device playback information of the first Bluetooth device, and is not repeated here.

[0258] In some embodiments, the display device 200 may be configured to unmute the second audio upon detecting that the currently used Bluetooth device has paused audio playback or upon detecting a disconnection from the currently used Bluetooth device. Disconnecting from the currently used Bluetooth device may include disconnecting the currently used Bluetooth device from the display device 200 or exiting the art mode application.

[0259] In some embodiments, the display device 200 may be configured to switch back to the audio sending mode, i.e., source mode, to serve as an audio source device when detecting that all connected Bluetooth devices are disconnected or after exiting the art mode application.

[0260] In some embodiments, the display device 200 displays a disconnection prompt when detecting that the connection with the currently used Bluetooth device is disconnected. The currently used Bluetooth device is the Bluetooth device that currently provides audio for the display device 200. For example, the first Bluetooth device is currently used, and the device name of the first Bluetooth device is my phone. Figure 21 The display page shown displays a disconnection prompt message, such as "disconnecting from my phone." In some embodiments, the disconnection prompt message can be automatically hidden after a preset time.

[0261] In some embodiments, if the display device 200 is in source mode and is connected to a third Bluetooth device that is in sink mode, such as a Bluetooth speaker, the display device 200 disconnects from the third Bluetooth device after switching to sink mode. After switching back to source mode, the display device 200 can automatically restore the connection with the third Bluetooth device.

[0262] In some embodiments, the display device 200 may further be configured with a second application for playing audio, and the second application is an application that uses the system Bluetooth function and is in audio receiving mode when using the system Bluetooth function.

[0263] After opening the second application, display device 200 enters the second mode. In the second mode, display device 200 functions as an audio receiving device, equivalent to a speaker, for receiving and playing audio sent by other Bluetooth devices. The second application may also be referred to as a speaker application, a speaker mode application, or a "my music" application. The second mode may also be referred to as speaker mode, "my music mode," or the like.

[0264] In the embodiment of the present application, a specific description is given by taking the second application as a speaker mode application and the second mode as a speaker mode as an example.

[0265] In some embodiments, the display device 200 may be configured to Figure 22 The process shown enters the speaker mode. The specific steps are as follows:

[0266] S2201 , in response to the user's operation of opening the speaker mode application, entering the speaker mode, and after entering the speaker mode, displaying an operation guide page and switching to the audio receiving mode.

[0267] In some embodiments, the control device 100 may be configured with a key dedicated to opening the speaker mode application, such as a music key, and the display device 200 may enter the speaker mode application in response to a user instruction input based on the music key.

[0268] In some embodiments, the display device 200 may set an icon of the speaker mode application on the main page, sidebar, and / or shortcut menu. The display device 200 may enter the speaker mode application in response to the user selecting the icon of the speaker mode application.

[0269] After entering the speaker mode application, the display device 200 will switch to the audio receiving mode, that is, switch to the sink mode. In this way, the display device 200 can serve as an audio receiving device in the speaker mode. After pairing and connecting with other Bluetooth devices, it can receive and play audio sent by other Bluetooth devices.

[0270] In some embodiments, after entering the speaker mode application, the display device 200 may, with reference to step S1201, turn on the first, second, and third Bluetooth switches to ensure the availability of the system Bluetooth function and to be discoverable by non-designated Bluetooth devices, thereby ensuring that the speaker mode is available. When exiting speaker mode or disconnecting from a Bluetooth device, the first, second, and third Bluetooth switches are restored to their default states, which will not be further described here.

[0271] The operation guide page in speaker mode can refer to the operation guide page in art mode, which will not be repeated here.

[0272] S2202: Display a pairing page according to the pairing request of the first Bluetooth device.

[0273] S2203: In response to the user's instruction to agree to pairing, pair with the first Bluetooth device, and display a prompt page after pairing with the first Bluetooth device is successful.

[0274] Steps S2202-S2203 can refer to steps S1202-S1203 and are not repeated here.

[0275] After successfully pairing with a Bluetooth device, the display device 200 saves the pairing information of the Bluetooth device so that after entering the speaker mode again, a list of paired devices can be displayed for the user to select a Bluetooth device that has been successfully paired from the list of paired devices, and the user can directly use the stored pairing information to quickly pair and connect with these Bluetooth devices. This process can refer to the process of establishing a connection with a paired Bluetooth device again in the art mode, which will not be repeated here.

[0276] In some embodiments, the display device 200 may automatically exit the prompt page after a first period of time.

[0277] In some embodiments, the display device 200 may exit the prompt page in response to an instruction input by the user using the back key of the control device 100 .

[0278] After exiting the prompt page, if the first Bluetooth device is not in the playing state, a waiting page may be displayed. The waiting page may be a default page of the speaker mode, for prompting the user to wait for the music to be played.

[0279] S2204: After receiving the first audio sent by the first Bluetooth device, display a music playing page and play the first audio.

[0280] In some embodiments, if a user uses a first Bluetooth device to play a first audio, the first Bluetooth device may send a play notification and the first audio to the display device 200. The display device 200 may determine that the first Bluetooth device is in an audio playback state based on the play notification, and after determining that the first Bluetooth device is in an audio playback state, exit the prompt page and display the music playback page.

[0281] In some embodiments, the implementation process of the display device 200 monitoring the audio playback status of the first Bluetooth device can refer to step S1204, which is not repeated here.

[0282] In some embodiments, the display device 200 displays device playback information on the music playback page. The device playback information may include a device name and a device icon of the first Bluetooth device. The device icon is used to identify a device type of the first Bluetooth device.

[0283] You can refer to Figure 23 In the music playing page shown, if the device type of the first Bluetooth device is a mobile phone and the device name is my phone, the music playing page may include an icon identifying a mobile phone and my phone.

[0284] In some embodiments, the music playback page may include audio information, a playback progress bar, playback controls, lyrics, a spectrum analysis graph, etc.

[0285] The audio information includes relevant information of the first audio currently being played, such as the audio name, audio introduction, etc. Figure 23 , the relevant information of the first audio includes the audio name, such as AAAA, and singer: BBBB.

[0286] The playback progress bar is used to indicate the total duration of the first audio and the current playback duration. Figure 23 As shown in the play progress bar 2301, the right end of the play progress bar 2301 displays the total duration of the first audio, such as 4 minutes and 23 seconds, and the left end of the play progress bar 2301 displays the played duration, such as 1 minute and 6 seconds.

[0287] The play control is used to control the play of the first audio, and may include a forward switch control and a backward switch control, wherein the forward switch control is used to switch to play the audio that is before the current audio in the current playlist, and the backward switch control is used to switch to play the audio that is after the current audio in the current playlist. Figure 23 The music playing page shown in FIG. 2 includes a forward switch control 2302 and a backward switch control 2303. When the current audio is playing, the play control may also include a pause play control for pausing the current audio. Figure 23 The music playing page shown in FIG. 2 includes a pause play control 2304. When the current audio is in a paused state, the play control also includes a start play control for starting to play the current audio. Figure 23 The music playback page shown includes a music playback control. In some embodiments, the display device 200 sends a control instruction to the first Bluetooth device in response to the user selecting the playback control, and the control instruction includes information about the playback control. The first Bluetooth device responds to the control instruction and performs a corresponding task based on the information of the playback control. For example, the control instruction includes information about switching controls forward. The first Bluetooth device switches to playing the previous audio and sends the previous audio to the display device 200, so as to achieve the effect of switching to playing the previous audio on the display device 200.

[0288] The lyrics are the lyrics corresponding to the current audio. The display device 200 can display the corresponding lyrics according to the playback progress of the first audio to achieve the effect of audio and video synchronization. Figure 23 The music playback page shown displays the corresponding lyrics, such as CCCCCCCC, when the playback progress is 1 minute and 6 seconds.

[0289] The spectrum analysis chart is used to show the frequency distribution and volume changes of the current audio, which can increase the interest of audio playback. Figure 23 The music playing page shown includes a spectrum analysis diagram 2305 of the first audio.

[0290] In some embodiments, if the display device 200 is currently playing a second audio, then upon recognizing that the first Bluetooth device is in an audio playback state, the second audio may be muted to prevent the second audio from affecting the playback quality of the first audio. The process of muting the second audio in speaker mode can be referenced to the process of muting the second audio in art mode and is not further described here.

[0291] In some embodiments, in the sound box mode, the display device 200 can simultaneously connect a first Bluetooth device and a second Bluetooth device, the number of the second Bluetooth device being at least 1, at this time, the display device 200 can switch the Bluetooth device providing audio. The display device 200 can switch the Bluetooth device providing audio according to the flow shown in Figure 24 The specific steps are as follows:

[0295] S2402, in response to an instruction of the user selecting an item of the second Bluetooth device, terminating receiving the first audio of the first Bluetooth device and starting receiving the third audio sent by the second Bluetooth device.

[0296] S2403, after receiving the third audio sent by the second Bluetooth device, playing the third audio.

[0297] Steps S2402-S2403 can refer to steps S1902-S1903, which are not described here.

[0298] When the display device 200 determines that the second Bluetooth device is in the audio playing state, the display device 200 displays the corresponding music playing page according to the third audio, and displays the device playing information of the second Bluetooth device in the music playing page.

[0299] In some embodiments, the display device 200 may be configured to unmute the second audio upon detecting that the currently used Bluetooth device has paused audio playback or upon detecting a disconnection from the currently used Bluetooth device. Disconnecting from the currently used Bluetooth device may include disconnecting the currently used Bluetooth device from the display device 200 or exiting the Art Mode application. The above process can be referenced to the corresponding process in Art Mode and is not further described here.

[0300] In some embodiments, the speaker mode application can also turn off the screen to play audio, and the display device 200 can Figure 26 The process shown adjusts the status of the display screen. The specific steps are as follows:

[0301] S2601, in response to the user's screen-off instruction, adjust the display screen to a screen-off state and keep playing the first audio.

[0302] In some embodiments, the speaker mode application may be configured with a screen-off button within the music playback page. The user may input a screen-off instruction by selecting the screen-off button.

[0303] In response to the screen-off instruction, the display device 200 adjusts the display screen to the screen-off state and keeps playing the first audio. In this way, the display device 200 no longer displays the picture and plays the audio as a simple speaker to avoid disturbing the user by displaying the picture.

[0304] S2602: In response to a screen-on instruction from the user, the display screen is adjusted to a screen-on state, and the first audio is kept playing.

[0305] The user can input a screen-on command by pressing any button on the control device 100, so that the display device 200 can be adjusted back to the screen-on state at any time to display the music playing page to the user. In addition, during this process, the first audio is always played to avoid affecting the user's auditory enjoyment.

[0306] For art mode applications and speaker mode applications, one focuses on visual display and the other focuses on auditory display. If the two can be switched, better audio-visual display effects can be achieved.

[0307] However, both the art mode application and the speaker mode application are configured to switch the display device 200 back to source mode when exiting the application. Therefore, after exiting the application, the display device 200 will not be able to serve as an audio receiving device to receive the audio provided by the audio sending device, and will not be able to continue playing the audio. That is to say, when the display device 200 plays audio as an audio receiving device, if it switches between art mode and speaker mode, it will inevitably switch to source mode due to exiting the current application, thereby disconnecting the Bluetooth device and interrupting the music playback. When entering the next mode, it is necessary to re-execute the process of manually connecting to the Bluetooth device before continuing to play music. In other words, when switching between art mode and speaker mode, the continuity of music playback cannot be guaranteed, resulting in a poor effect of combining art mode and speaker mode.

[0308] Based on the above analysis of the reasons for interrupting music playback, it can be known that the fundamental reason for the interruption of music playback is that the display device 200 switches from sink mode back to source mode. In order to solve the above problems, an embodiment of the present application provides a method for switching between art mode and speaker mode, so as to avoid interrupting audio playback by locking the system Bluetooth function to be on, and locking the sink mode. That is to say, when the art mode application is switched from the speaker mode application, it is necessary to keep the first Bluetooth switch in the on state, and keep the Bluetooth mode in the audio receiving mode. When the speaker mode application is switched from the art mode application, it is necessary to keep the first Bluetooth switch in the on state, and keep the Bluetooth mode in the audio receiving mode.

[0309] In some embodiments, the display device 200 may be configured to Figure 27 The process shown switches from speaker mode to art mode. The specific steps are as follows:

[0310] S2701 , in speaker mode, in response to a user's switching instruction, identifying a target application after switching.

[0311] Based on step S2201, it can be seen that after entering the speaker mode application, the display device 200 automatically switches to sink mode. In speaker mode, the currently connected first audio device may be in an audio playback state or not in an audio playback state, or, in speaker mode, the display device 200 may not be connected to a Bluetooth device. In other words, as long as it is in speaker mode, the display device 200 is in sink mode.

[0312] If the user wants to use the target application, the user can open the target application through a switching instruction.

[0313] Taking the target application as an art mode application as an example, in some embodiments, the user can input a switching instruction through a key dedicated to the art mode on the control device 100, such as the art mode key, to instruct the display device 200 to open the art mode application.

[0314] In some embodiments, the display device 200 may be configured with an icon for an art mode application in a sidebar or shortcut menu. In this way, the user can control the display device 200 to open the sidebar or shortcut menu and input a switching instruction by selecting the icon for the art mode application. In speaker mode, the user can input a menu instruction by using the menu key of the control device 100 to instruct the display device 200 to open the sidebar or shortcut menu. Figure 28 In the music playing page shown in ①, the display device 200 can display a sidebar 2801 on the music playing page in response to the menu command. The sidebar 2801 can include an icon of the art mode application. Figure 28 In the music playing page shown in ②, the display device 200 can display a shortcut menu 2802 on the music playing page in response to the menu instruction. The shortcut menu 2802 can include an icon of the art mode application.

[0315] In some embodiments, based on the method of starting the art mode, the user can input a switching instruction by short pressing the power button.

[0316] In response to the switching instruction, the display device 200 switches to display the page of the target application.

[0317] In some embodiments, the display device 200 can identify the target application by identifying the top activity. For example, if the top activity is identified as art mode, the target application can be determined to be an art mode application. If the top activity is not identified as art mode, the target application can be determined to be another application rather than an art mode application.

[0318] In other embodiments, the display device 200 can identify the target application by monitoring key events. Based on a key event for launching an art mode application, such as an art mode key event, a power key event, or an OK key event based on an art mode application icon, if the monitored key event is a first designated key event, such as an art mode key event, a power key event, or an OK key event based on an art mode application icon, the target application can be determined to be an art mode application. If the monitored key event is not an art mode key event, a power key event, or an OK key event based on an art mode application icon, the target application can be determined to be another application rather than an art mode application.

[0319] S2702: If the target application is an art mode application, enter the art mode, lock the first Bluetooth switch to be in the on state, and lock the Bluetooth mode to be in the audio receiving mode.

[0320] If the target application is an art mode application, then to ensure the continuity of audio playback, the system Bluetooth function must be always available to ensure that the connection with the Bluetooth device is not disconnected, and the display device 200 must always be in sink mode to receive audio sent by the audio sending device. Therefore, the display device 200 locks the system Bluetooth function in the open state and locks it in sink mode.

[0321] In some embodiments, in speaker mode, the display device 200 is in sink mode. If the display device 200 is connected to a first Bluetooth device and plays the first audio provided by the first Bluetooth device, the user can browse the audio information of the first audio through the music playback page and control the playback of the first audio. If the user wants to browse art paintings at the same time, he can switch to art mode, such as pressing the power button, the art mode button, or selecting the icon of the art mode application in the sidebar / shortcut menu. After entering art mode, the display device 200 will display the display page of the art mode application and display art paintings on the display page. After the display device 200 recognizes that the switched application is an art mode application, it locks the system Bluetooth function to be on and locks it in sink mode. In this way, the display device 200 can always maintain a connection with the first Bluetooth device and receive the first audio sent by the first Bluetooth device during the process of switching to art mode, which can ensure the continuous playback of the first audio.

[0322] In some embodiments, in speaker mode, the display device 200 is in sink mode. If the display device 200 is not connected to a Bluetooth device, after switching to art mode, the system Bluetooth function is locked to be turned on and locked in sink mode. In art mode, the display device 200 can respond to the user's operation to open the Bluetooth music function of the application and directly pair and connect with the first Bluetooth device without switching modes.

[0323] In some embodiments, after switching to Art Mode, if it is detected that a first Bluetooth device is currently connected and is in audio playback mode, the device playback information of the first Bluetooth device can be displayed on the display page and hidden after a preset time. In this way, the user can be prompted to the currently used Bluetooth device after switching modes.

[0324] S2703, if the target application is not the art mode application, then the default state of the first Bluetooth switch is restored, and the Bluetooth mode is switched back from the audio receiving mode to the audio sending mode.

[0325] If the switched application is not the art mode application, it means that the display device 200 is not currently in the sound box mode, nor in the art mode, which is equivalent to directly exiting the sound box mode. The display device 200 restores the default state of the system Bluetooth function, and switches back to the source mode.

[0326] In some embodiments, the display device 200 can switch from the sound box mode to the art mode according to the flow shown in FIG. 9, and the specific steps are as follows: Figure 29

[0327] S2901, in the art mode, in response to the switching instruction of the user, the target application after switching is identified, and whether the Bluetooth mode is in the audio receiving mode is identified.

[0328] In some embodiments, the display device 200 switches to the sink mode in response to the user's operation of opening the application Bluetooth music function in the art mode. Wherein, when the display device 200 does not establish a connection with the Bluetooth device, if the display device 200 displays the operation guide page or the pairing page, the display device 200 is in the sink mode. If the display device 200 exits the operation guide page or the pairing page in response to the user's instruction, the display device 200 switches back to the source mode. After the display device 200 establishes a connection with the Bluetooth device, the display device 200 remains in the sink mode. If the display device 200 disconnects after establishing a connection with the Bluetooth device, it will switch back to the sink mode.

[0329] If the user wants to use the target application, the target application can be opened by the switching instruction.

[0330] Taking the target application as the sound box mode application as an example, in some embodiments, the user can input the switching instruction through the key dedicated to the sound box mode on the control device 100, such as the music key, to instruct the display device 200 to open the sound box mode application.

[0331] In some embodiments, the display device 200 can be configured with an icon of the sound box mode application in the sidebar or the shortcut menu. In this way, the user can control the display device 200 to open the sidebar or the shortcut menu, and input the switching instruction by selecting the icon of the art mode application. In the sound box mode, the user can input the menu instruction through the menu key of the control device 100 to instruct the display device 200 to open the sidebar or the shortcut menu. For details, please refer to Figure 28 ​In the music playing page shown in ①, the display device 200 can display a sidebar 2801 on the music playing page in response to the menu command. The sidebar 2801 can include an icon of the speaker mode application. Figure 28 In the music playing page shown in ②, the display device 200 can display a shortcut menu 2802 on the music playing page in response to the menu instruction. The shortcut menu 2802 can include an icon of the speaker mode application.

[0332] In response to the switching instruction, the display device 200 switches to display the page of the target application.

[0333] In some embodiments, the display device 200 can identify the target application by identifying the top activity. For example, if the top activity is identified as "my music" (a speaker mode application), the target application can be determined to be a speaker mode application. If the top activity is not identified as "my music," the target application can be determined to be another application, not a speaker mode application.

[0334] In other embodiments, the display device 200 can identify the target application by monitoring key events. Based on a key event for starting a speaker mode application, such as a music key event or an OK key event based on an icon of a speaker mode application, if the monitored key event is a second specified key event, such as a music key event or an OK key event based on an icon of a speaker mode application, it can be determined that the target application is a speaker mode application. If the monitored key event is not a music key event or an OK key event based on an icon of a speaker mode application, it can be determined that the target application is not a speaker mode application but another application.

[0335] S2902: If the target application is a speaker mode application, enter the speaker mode, lock the first Bluetooth switch to be in the on state, and lock the Bluetooth mode to be in the audio receiving mode.

[0336] If the target application is a speaker mode application, then in order to ensure the continuity of audio playback, it is necessary to ensure that the system Bluetooth function is always available to ensure that the connection with the Bluetooth device is not disconnected, and to ensure that the display device 200 is always in sink mode to receive audio sent by the audio sending device. Therefore, the display device 200 locks the system Bluetooth function in the on state and locks it in sink mode.

[0337] In some embodiments, in the art mode, the display device 200 is in the sink mode. If the display device 200 connects a first Bluetooth device based on the application of the Bluetooth music function, and plays the first audio provided by the first Bluetooth device, the display device 200 displays the art painting, and plays the first audio. If the user wants to browse the audio information of the first audio, and control the playing of the first audio through the display device 200, the audio box mode can be switched to, such as pressing the music key or selecting the icon of the audio box mode application in the sidebar / shortcut menu, etc. After the display device 200 identifies that the application after switching is the audio box mode application, the system Bluetooth function is locked in the on state, and the sink mode is locked. In this way, the display device 200 can always maintain the connection with the first Bluetooth device and receive the first audio sent by the first Bluetooth device during the switching to the audio box mode, that is, the continuous playing of the first audio can be ensured. In the audio box mode, the display device 200 will display a music playing page, and display the audio information of the first audio in the music playing page, etc.

[0338] In some embodiments, in the art mode, the display device 200 is in the sink mode, but has not connected a Bluetooth device, such as in the display operation guide page or the pairing page, after switching to the audio box mode, the system Bluetooth function is locked in the on state, and the sink mode is locked. In the audio box mode, the display device 200 can directly pair and connect with the first Bluetooth device without switching the mode.

[0339] In some embodiments, after switching to the audio box mode, if it is detected that the first Bluetooth device is currently connected, the device playing information of the first Bluetooth device can be displayed on the music playing page. In this way, the user can be prompted about the currently used Bluetooth device after switching the mode.

[0340] S2903, if the target application is not the audio box mode application, the default state of the first Bluetooth switch is restored, and the Bluetooth mode is switched back to the audio sending mode from the audio receiving mode.

[0341] If the application after switching is not the audio box mode application, it means that the display device 200 is not currently in the art mode, nor in the audio box mode, which is equivalent to directly exiting the art mode. The display device 200 restores the default state of the system Bluetooth function, and switches back to the source mode.

[0342] In some embodiments, the display device 200 can use the BluetoothSinkManager class to manage the activation and deactivation of the system's Bluetooth function, as well as switching between source and sink modes. For example, identifying the target application by identifying the top activity can be encapsulated within the BluetoothSinkManager class to determine the current top activity. MyMusicActivity and ArtModeActivity each enable sink mode in their onCreate method and determine whether to stop sink mode based on the top activity in their onStop method.

[0343] refer to Figure 30 As shown, the display device 3000 in some embodiments includes: an audio output module 3001 , a Bluetooth module 3002 , a display 3004 , and a controller 3005 . The controller 3005 is in communication with the audio output module 3001 , the Bluetooth module 3002 , and the display 3004 .

[0344] The audio output module 3001 is used to play audio. The audio output module 3001 is a component capable of playing audio and can be a speaker of the display device 3000 or an external audio output device connected to the display device 3000. The display device 3000 is a type of display device 3000, and the audio output module 3001 can be the audio output device 270 involved in the above-mentioned embodiment.

[0345] The Bluetooth module 3002 is a near field communication module that enables the display device 3000 to establish a Bluetooth connection with at least one external Bluetooth device. The Bluetooth module 3002 may be the module for implementing Bluetooth communication in the communication device 220 involved in the above embodiment.

[0346] In some embodiments, the display device 3000 further includes an input interface 3003 for acquiring operation information, and the input interface 3003 is communicatively connected to the controller 3005 .

[0347] The input interface 3003 is an interface capable of receiving user operations. The specific form of the input interface 3003 is not limited, as long as it can receive user operations. The controller 3005 can convert the operation information obtained through the input interface 3003 into control instructions for the display device 3000.

[0348] In some embodiments, if the display device 3000 needs to or can be used in conjunction with a TV remote control, the input interface 3003 can be an interface used by the display device 3000 to receive remote control information from the TV remote control, so that the remote control information received from the TV remote control can be used as the obtained operation information.

[0349] In some embodiments, if the display device 3000 is a display device 3000 having a touch display 3004 , the input interface 3003 may also be the touch display 3004 of the display device 3000 , so that the touch operation detected on the touch screen may be used as the acquired operation information.

[0350] In some embodiments, the display device 3000 may also be configured with a sound collector (e.g., a microphone). In this case, the input interface 3003 may include the sound collector and use the audio information collected by the sound collector as the acquired operation information. As one type of display device 3000, the sound collector may be the sound collector in the detector 230 described in the above embodiments.

[0351] In some embodiments, the display device 3000 may also be configured with an image collector (e.g., a camera). In this case, the input interface 3003 may include the image collector and use the image information collected by the image collector as the acquired operation information. As one type of display device 3000, the image collector may be the image collector in the detector 230 described in the above embodiments.

[0352] In some embodiments, the display device 3000 may also be configured with buttons. In this case, the input interface 3003 may include buttons, and use the received information on the operation of the buttons as the acquired operation information.

[0353] based on Figure 30 The display device 3000 shown, in some embodiments:

[0354] The audio output module 3001 is configured to play audio;

[0355] The Bluetooth module 3002 is configured to establish a Bluetooth connection with at least one external Bluetooth device;

[0356] Display 3004, configured to display a display page of the first application;

[0357] Among them, the audio played by the audio output module 3001 can specifically be the audio in the audio and video content currently playing in the display device 3000, or it can be the audio sent by an external Bluetooth device. The controller 3005 can control the audio source played in the audio output module 3001.

[0358] For example, in the case that the display device 3000 is not connected with an external Bluetooth device, or the external Bluetooth device does not send audio to the display device 3000, the display device 3000 will play the system-provided audio; in the case that the display device 3000 is connected with at least one external Bluetooth device through the Bluetooth module 3002, and receives audio sent by one of the external Bluetooth devices, the controller 3005 will switch the currently played audio to the audio sent by the external Bluetooth device.

[0359] The Bluetooth module 3002 is the core component for the display device 3000 to implement Bluetooth functions. The Bluetooth module 3002 is responsible for wireless connection and data transmission with other external Bluetooth devices. The Bluetooth module 3002 is a PCBA board integrated with Bluetooth functions, used for short-range wireless communication. The Bluetooth module 3002 integrates chips and peripheral hardware circuits, and develops the required built-in programs to implement Bluetooth functions. The Bluetooth module 3002 can perform data transmission with MCUs (microcontrollers) or other control devices through relevant interfaces, to implement Bluetooth standard communication and networking. Taking a smart TV as an example, on the smart TV, the Bluetooth module 3002 is mainly used for wireless connection with other external Bluetooth devices, to implement functions such as audio transmission and device control.

[0360] The display 3004 is used for picture display. In the case that the first application is in a starting state, the display 3004 displays the display page of the first application. When the first application starts, the controller 3005 can control the display device 3000 to switch from a current mode to a first mode. The first mode is a system mode configured for the first application. The current mode can be a default system mode of the display device 3000, or a system mode configured for other applications. The system mode configured for an application can define specific display and playing modes.

[0361] Each system mode of the display device 3000 can correspond to specific display and playing modes. That is, in different system modes, the display device 3000 can display specific content through the display 3004 in a specific display mode, and play specific audio through the audio output module 3001 in a specific playing mode. In some embodiments, the display and playing modes corresponding to each system mode of the display device 3000, and the specific content displayed and the specific audio played, can be default settings, or can be set by the user.

[0362] In some optional embodiments, the system mode configured for the display device 3000 includes at least a default system mode and a first mode configured for the first application. Before the display device 3000 launches the first application, the display device 3000 is in the default system mode. When the display device 3000 launches the first application, the controller 3005 controls the display device 3000 to switch from the default system mode to the first mode.

[0363] In some embodiments, the display device 3000 opens the first application and enters the first mode. The display page of the first application is displayed on the display 3004 in any of the following implementations:

[0364] In some embodiments, when the display device 3000 is powered off, the controller 3005 responds to a first instruction input by a user by short pressing the power button of a remote control device, starts a first application and enters a first mode after the display device 3000 is powered on, and displays a display page of the first application on the display 3004 .

[0365] In some embodiments, when the display device 3000 is powered off, the controller 3005 displays the system homepage on the display 3004 in response to a user long-pressing the power button of a remote control device. In response to a first instruction input by a user short-pressing the power button or the home button of the remote control device, the controller 3005 launches a first application and, after launching the first application, enters a first mode, switching the display content of the display 3004 from the system homepage to the display page of the first application. The methods for identifying and determining short-press and long-press operations can refer to the above embodiments.

[0366] In some embodiments, a first mode key, such as an art mode key, is configured on the remote control of the display device 3000. When the display device 3000 is powered off, the controller 3005 responds to a first instruction input by a user via the first mode key of the remote control to launch a first application and enter the first mode after the display device 3000 is powered on, and displays a display page of the first application on the display 3004.

[0367] In some embodiments, when the display device 3000 is in the on state and has not entered the first mode, if the controller 3005 detects that the preset system mode switching conditions are met, it can automatically trigger the opening of the first application to switch into the first mode, and switch the display content of the display 3004 from the current page to the display page of the first application.

[0368] In some embodiments, when the display device 3000 is in the power-on state and has not entered the first mode, the controller 3005 responds to the first instruction input by the user by short pressing the power button of the remote control device, starts the first application to enter the first mode, and switches the display content of the display 3004 from the current page to the display page of the first application.

[0369] In some embodiments, when the display device 3000 is in the power-on state and has not entered the first mode, the controller 3005 responds to a first instruction input by the user based on the art mode key of the remote control device, starts the first application to enter the first mode, and switches the display content of the display 3004 from the current page to the display page of the first application.

[0370] In some embodiments, when the display device 3000 is powered on and not in the first mode, the controller 3005 responds to a voice command to launch a first application, launches the first application, enters the first mode, and switches the display content of the display 3004 from the current page to the display page of the first application. The voice command to launch the first application can be obtained by keyword matching the input voice, etc. The keyword matching can be achieved through one or a combination of exact matching and fuzzy matching.

[0371] In some embodiments, if the user turns on the scheduled power-on and sets the power-on time, the display device 3000 is in the off state. If the controller 3005 detects that the system time reaches the power-on time, the first application is started after powering on and enters the first mode, and the display page of the first application is displayed on the display 3004.

[0372] In some embodiments, when the display device 3000 displays the system homepage, it is in the default system mode. In response to a user selecting an icon of a first application, the controller 3005 launches the first application and controls the display device 3000 to switch from the default system mode to the first mode. The icon of the first application can be configured on the system homepage or in a sidebar of the system homepage.

[0373] The first application may be an application configured on the display device 3000. In some optional embodiments, the first application may be a system application pre-installed when the display device 3000 leaves the factory, or an application downloaded and installed on the display device 3000 as needed by the user.

[0374] In some embodiments, the display device 3000 can set different system modes for configured applications. For example, when a first application is launched on the display device 3000, the display device 3000 enters the first mode; for another example, when a second application is launched on the display device 3000, the display device 3000 enters the second mode.

[0375] In the first mode, the display 3004 will display the display page of the first application. The display page of the first application is used to display corresponding content according to the configuration parameters. In some optional embodiments, the display page of the first application can be the homepage of the first application, that is, the first page displayed after opening the first application and entering the first mode. The display page can also be a content display interface specified by the user.

[0376] In some optional embodiments, the content displayed on the display page of the first application includes artwork. The artwork can be divided into different categories based on scene, image content, etc. Users can quickly search for artwork by category and select their favorite artwork to be displayed on the display page of the first application. For details on the specific categories and presentation of artwork, as well as how users select artwork, please refer to the above embodiments.

[0377] In some embodiments, the artwork displayed on the display page of the first application includes artwork images and dynamic artwork. The dynamic artwork can be regarded as a collection of multiple frames of images, which are played sequentially or in a loop to present a dynamic display effect.

[0378] In some embodiments, the display device 3000 plays audio configured for the dynamic artwork while displaying it, creating a sense of ambiance for the user. However, the audio configured for the dynamic artwork may not be the user's favorite music, and the display device 3000 does not play audio when displaying the artwork images, resulting in a lack of ambiance for the user when viewing the artwork.

[0379] In order to solve the above problem, in an embodiment of the present application, the first application has a built-in application Bluetooth function. In the first mode, the user can establish a Bluetooth connection with an external Bluetooth device through the application Bluetooth function without exiting the first application. The user can control the external Bluetooth device to send his or her favorite audio to the display device 3000, so that the audio can be played through the display device 3000 while the art painting is displayed on the display device 3000, so that the user can appreciate his or her favorite art painting while listening to his or her favorite music, creating an atmosphere that matches the user's personalized preferences.

[0380] In some embodiments, the controller 3005 is configured to: display the application Bluetooth switch built into the first application on the display page of the first application; control the Bluetooth module 3002 to be in a connectable state in response to a trigger operation on the application Bluetooth switch; when at least one external Bluetooth device establishes a Bluetooth connection with the display device 3000, display the device information of the external Bluetooth device on the display page; receive the first audio sent by the external Bluetooth device through the Bluetooth module 3002, and play the first audio through the audio output module 3001 while the display 3004 displays the display page.

[0381] The application Bluetooth switch refers to the Bluetooth switch control built into the first application. It should be noted that the application Bluetooth switch is different from the system Bluetooth switch of the display device 3000. The system Bluetooth switch is a switch control displayed in the system settings, while the application Bluetooth switch is a switch control displayed in the first application. Users can trigger and control the application Bluetooth switch without exiting the first application, effectively simplifying user operations.

[0382] The application Bluetooth switch can be called through an interface to control the state of the system Bluetooth. For example, when the system Bluetooth switch is off, when the application Bluetooth switch is triggered to turn on in the display page of the first application, the system Bluetooth can be turned on through the interface call.

[0383] The Bluetooth module 3002 has two connection states: connectable and disconnected. The connection state of the Bluetooth module 3002 can be controlled by the system Bluetooth switch. When the system Bluetooth switch is on, the Bluetooth module 3002 is in a connectable state, and an external Bluetooth device can establish a Bluetooth connection with the display device 3000. When the system Bluetooth switch is off, the Bluetooth module 3002 is in a disconnected state, and an external Bluetooth device cannot establish a Bluetooth connection with the display device 3000.

[0384] In some embodiments, when the Bluetooth module 3002 is in a connectable state, the external Bluetooth device can find the display device 3000 through Bluetooth search and establish a Bluetooth connection with the display device 3000. When the external Bluetooth device establishes a Bluetooth connection with the display device 3000 for the first time, the Bluetooth connection can be established through Bluetooth pairing. When this is not the first time the external Bluetooth device establishes a Bluetooth connection with the display device 3000, the Bluetooth connection can be directly established based on the historical record information.

[0385] During the process of establishing a Bluetooth connection between the external Bluetooth device and the display device 3000 , the display device 3000 does not need to exit the first application and maintains displaying the display page of the first application.

[0386] In some embodiments, when at least one external Bluetooth device successfully establishes a Bluetooth connection with the display device 3000, device information of the at least one successfully connected external Bluetooth device will be displayed on the display page of the first application. In some embodiments, the device information of the external Bluetooth device can be a device icon, device model, or other identifier representing the external Bluetooth device, which is not limited here.

[0387] The number of external Bluetooth devices that have successfully established a Bluetooth connection with the display device 3000 may be one, two, or more. The device information displayed on the display page may be the last external Bluetooth device to establish a Bluetooth connection, or the external Bluetooth device that successfully sent audio to the display device 3000. The specific display method can be set according to actual conditions.

[0388] In this embodiment, during the process of establishing a Bluetooth connection between the external Bluetooth device and the display device 3000, there is no need to exit the first application. The application Bluetooth switch can be directly triggered on the display page of the first application to put the Bluetooth module 3002 of the display device 3000 into a connectable state. Each link can be implemented while displaying the display page of the first application, which can simplify user operations and achieve Bluetooth connection between the external Bluetooth device and the display device 3000. At the same time, by displaying the device information of the successfully connected external Bluetooth device on the display page, the user can intuitively understand the Bluetooth connection status between the external Bluetooth device and the display device 3000. In addition, the Bluetooth module 3002 can receive the first audio sent by the external Bluetooth device and play the first audio through the audio output module 3001 while the display 3004 displays the display page. While the display device 3000 displays the content of the display page, the user's favorite audio can be played at the same time, thereby achieving the effect of improving the user experience.

[0389] In some embodiments, the operating modes of the Bluetooth module 3002 include an audio source mode (SOURCE mode) and an audio sink mode (SINK mode).

[0390] In some embodiments, the controller 3005 is further configured to: when the Bluetooth module 3002 is in the audio source mode, in response to a trigger operation on the application Bluetooth switch, control the Bluetooth module 3002 to switch from the audio source mode to the audio receiving mode.

[0391] In some other embodiments, the controller 3005 is further configured to: when the Bluetooth module 3002 is in the audio receiving mode, in response to a triggering operation on the application Bluetooth switch, control the Bluetooth module 3002 to maintain the audio receiving mode.

[0392] Audio sink mode (SINK mode) and audio source mode (SOURCE mode) are two operating modes specified in the Bluetooth Advanced Audio Distribution Profile (A2DP). A2DP is a Bluetooth high-quality audio transmission protocol used for transmitting mono and two-channel music (typically stereo in A2DP). This protocol clearly distinguishes between the sender (SOURCE) and receiver (SINK) of audio data.

[0393] Sink mode: The Bluetooth module 3002 acts as a sink device, receiving audio data. It receives audio data from the sender and decompresses it into PCM data using the codec corresponding to the source device. The data is then passed to the sound card for playback. The Bluetooth module 3002 can receive audio, video, or data files from other external Bluetooth devices (such as mobile phones and tablets).

[0394] SOURCE mode: The Bluetooth module 3002 acts as the source device and sends audio data. It compresses PCM (Pulse Code Modulation) data into a specific audio format using a codec (such as SBC, MPEG-1 / 2 Audio, or AAC) and transmits it to the receiver via the Audio / Video Distribution Transport Protocol (AVDTP). The Bluetooth module 3002 can send audio, video, or data files to other external Bluetooth devices.

[0395] For display devices, it is possible to switch between the two working modes of SINK mode and SOURCE mode under certain conditions. The switching methods include the following:

[0396] The first is automatic switching: In most cases, the Bluetooth module 3002 of the display device 3000 automatically switches modes based on the connected external Bluetooth device and the current communication needs. For example, when a user uses Bluetooth to send music from a mobile phone to the TV for playback, the TV's Bluetooth module 3002 automatically enters the SINK mode.

[0397] The second method is to control the switching through an external device: when the display device 3000 supports controlling the Bluetooth mode through an external device (such as a remote control, an application, etc.), the working mode of the Bluetooth module 3002 can be tried to be switched through the external device.

[0398] The third is system settings or developer options switching: on some display devices 3000, such as high-end TVs or TVs with developer options, users are allowed to change the working mode of the Bluetooth module 3002 through system settings or developer options.

[0399] In an embodiment of the present application, the switching between the SINK mode and the SOURCE mode can be based on the current operating mode of the Bluetooth module 3002300 and controlled by applying a Bluetooth switch. Specifically, when the Bluetooth module 3002 is in the audio source mode, the controller 3005 controls the Bluetooth module 3002 to switch from the audio source mode to the audio receiving mode in response to a triggering operation for the application of the Bluetooth switch. When the Bluetooth module 3002 is in the audio receiving mode, the controller 3005 controls the Bluetooth module 3002 to maintain the audio receiving mode in response to a triggering operation for the application of the Bluetooth switch.

[0400] In this embodiment, when the first application is turned on, that is, the display device 3000 enters the first mode, as long as the user turns on the application Bluetooth switch in the first application, the controller 3005 will automatically control the Bluetooth module 3002 to be placed in the audio receiving mode, so that the Bluetooth module 3002 is in a state where it can receive audio sent by an external Bluetooth device, which can better match the playback method in the first mode.

[0401] Since when the first application is opened, that is, the display device 3000 enters the first mode, it is necessary to set the working mode of the Bluetooth module 3002 to the audio receiving mode by applying the Bluetooth switch, so that the Bluetooth module 3002 can receive audio sent by the external Bluetooth device. When exiting the first application, the controller 3005 also needs to control the working mode of the Bluetooth module 3002 to be restored to the default working mode.

[0402] In some embodiments, when the default operating mode of the Bluetooth module 3002 is the audio source mode, the controller 3005 is further configured to: when the Bluetooth module 3002 is in the audio receiving mode, in response to an exit operation of exiting the first application, control the Bluetooth module 3002 to switch from the audio receiving mode to the audio source mode. When the Bluetooth module 3002 is in the audio source mode, in response to an exit operation of exiting the first application, control the Bluetooth module 3002 to continue to maintain the audio source mode.

[0403] In other embodiments, when the default operating mode of the Bluetooth module 3002 is the audio receiving mode, the controller 3005 is further configured to: when the Bluetooth module 3002 is in the audio receiving mode, in response to an exit operation of exiting the first application, control the Bluetooth module 3002 to continue to maintain the audio receiving mode.

[0404] In this embodiment, the event of exiting the first application is linked to the working mode adjustment of the Bluetooth module 3002, so that the working mode of the Bluetooth module 3002 can be restored to the default working mode when exiting the first application, so that the working mode of the Bluetooth module 3002 will match the playback mode of the first mode only when the first application is opened, that is, the display device 3000 enters the first mode, thereby enhancing the adaptability of the switching of the working mode of the Bluetooth module 3002 to the first mode, and will not affect the Bluetooth status in other system modes of the display device 3000.

[0405] In some embodiments, displaying the application Bluetooth switch built into the first application on the display page of the first application includes:

[0406] When the display device 3000 opens the first application, in response to the first remote control signal sent by the remote control device of the display device 3000, the application menu built into the first application is displayed on the display page of the first application; and the application Bluetooth switch is displayed in the application menu.

[0407] The first remote control signal is used to trigger the built-in application menu to display the built-in application menu of the first application.

[0408] The remote control device is a device for sending remote control signals to control the display device 3000. The remote control device can specifically be the control device 100 in the above embodiment. In some embodiments, when the display device 3000 is a smart TV, the remote control device can be a remote controller that is compatible with the smart TV.

[0409] Among them, the first application is configured with a built-in application menu. The built-in application menu of the first application is different from the system settings menu and can be opened directly in the first application to set parameters. The menu options in the application menu include parameter configuration options only for the first application, and call options for the system settings interface. It should be noted that the parameters set for the call options of the system settings interface are only effective during the opening of the first application. After exiting the first application, the set parameters will be restored to the original parameters or default parameters before the settings.

[0410] In some embodiments, when the display device 3000 opens a first application, on the display page of the first application, calling up and displaying the application menu built into the first application can be implemented in any one of the following ways:

[0411] In some embodiments, when the display device 3000 opens the first application, the controller 3005 responds to the second instruction input by the user pressing the menu key of the remote control device, calls up the application menu built into the first application, and displays the menu options of the application menu on the display page of the first application, each menu option including the application Bluetooth switch.

[0412] In some embodiments, when the display device 3000 opens a first application, the controller 3005, in response to a voice command to open an application menu built into the first application, invokes the application menu built into the first application and displays menu options of the application menu on the display page of the first application. The voice command to open the application menu built into the first application can be obtained by keyword matching the input voice, etc. The keyword matching can be achieved through one or a combination of exact matching and fuzzy matching.

[0413] In some embodiments, when the display device 3000 opens the first application, the controller 3005, in response to the user pressing the settings key among the physical keys of the display device, calls up the application menu built into the first application and displays the menu options of the application menu on the display page of the first application.

[0414] In some embodiments, when displaying a display page of a first application, the display device 3000 can open an application settings menu for the first application in response to a first remote control signal input by a user using a first button of a remote control device. In some embodiments, the first button of the remote control device can be a menu button, a color button, etc., and can be configured according to actual needs.

[0415] It is understood that in some embodiments, the first remote control signal sent by the remote control device can be universal for different applications. For example, when opening a first application, the first remote control signal can be used to open the application menu built into the first application. When opening a second application, the first remote control signal can also be used to open the application menu built into the second application. In other embodiments, different remote control signals can also be used to open the application menu built into different applications.

[0416] In some embodiments, the application menu built into the application can be displayed on top of the display page through a pop-up window, floating layer, etc. When the user uses the application menu, they can simultaneously browse the content displayed on the display page, and can observe the effect of the settings made through the application menu while setting parameters. For the specific processing method of the application setting menu, please refer to the application setting menu 901 in the above embodiment.

[0417] In this embodiment, after opening the first application, the user can use the remote control device to directly open the application menu of the first application content in the first application, providing the user with a convenient and quick built-in application menu invocation method. Moreover, the application menu invoked by the remote control signal can directly display the application Bluetooth switch on the display page, making it convenient for the user to trigger the application Bluetooth switch for operation, providing a simple and convenient processing method.

[0418] In some embodiments, the controller 3005 is further configured to: when the display device 3000 does not open the first application, respond to a second remote control signal sent by the remote control device of the display device 3000, open the first application and display the display page of the first application.

[0419] The second remote control signal is used to control the opening of the first application.

[0420] In some embodiments, the first remote control signal and the second remote control signal emitted by the remote control device may be the same signal or different signals. When the display device 3000 receives the first remote control signal or the second remote control signal, it determines how to execute the first remote control signal or the second remote control signal based on the content currently displayed on the display device 3000.

[0421] For example, the first remote control signal and the second remote control signal are control signals sent via different buttons or different button combinations on the remote control device. For example, the second remote control signal is sent by pressing the power button on the remote control device to open the first application, and then the first remote control signal is sent by pressing the menu button on the remote control device to call up the application menu of the first application.

[0422] For another example, the first remote control signal and the second remote control signal are control signals sent by the same button on the remote control device. By first pressing the set button on the remote control device to send the second remote control signal, the first application is opened, and then the set button is pressed again on the remote control device to send the first remote control signal, which calls up the application menu in the first application. Because the content displayed on the display device 3000 is different when the set button is pressed twice on the remote control device, the controller 3005 of the display device 3000 generates different control signals after receiving the first remote control signal and the second remote control signal.

[0423] In this embodiment, the first application is opened by the second remote control signal, the built-in application menu is called up in the first application by the first remote control signal, and the application Bluetooth menu is displayed. Through simple interaction, the application Bluetooth menu can be displayed in the first application, which facilitates the user to control the external Bluetooth device to establish a Bluetooth connection with the display device 3000.

[0424] In some embodiments, the application menu includes a plurality of menu options; and in response to the triggering operation of the application Bluetooth switch, controlling the Bluetooth module 3002 to be in a connectable state includes:

[0425] In response to a menu option selection operation triggered by the remote control device, when the selected menu option is to apply the Bluetooth switch, the Bluetooth module 3002 is controlled to be in a connectable state.

[0426] In some optional embodiments, the first application can configure the switch of the application Bluetooth function, i.e., the application Bluetooth switch, in the application menu. The menu options of the application menu include the application Bluetooth switch, such as BT Music. Accordingly, the user's operation of turning on the application Bluetooth switch can be: when the display device 3000 opens the first application display page, the user inputs a menu command through the menu key of the remote control device to control the display device 3000 to open the application menu. Multiple menu options are displayed in the application menu. The user can use the remote control device to control the selection of the application Bluetooth switch from the multiple menu options and trigger the confirmation operation. When the display device 3000 receives the remote control signal for selecting the application Bluetooth switch, it turns on the application Bluetooth switch and controls the Bluetooth module 3002 to be in a connectable state.

[0427] In other optional embodiments, the first application can configure the application Bluetooth switch in the first mode setting page. The first mode setting page includes an application Bluetooth switch, such as BT Music. Accordingly, the user's operation of turning on the application Bluetooth switch can be: when the display device 3000 opens the first application display page, the user inputs a menu command through the menu key of the remote control device to control the display device 3000 to open the application menu, and opens the first mode setting page by selecting the menu option of the first mode setting in the application menu. By selecting the application Bluetooth switch in the first mode setting page, the application Bluetooth function is turned on.

[0428] In this embodiment, an implementation method is provided for triggering the application Bluetooth switch by selecting it in the application menu of the displayed page. The application Bluetooth switch is integrated into the application menu as a menu option. The application Bluetooth switch can be triggered by selecting a menu item based on the application menu, which simplifies user operations and improves the convenience of operation.

[0429] In some embodiments, the controlling the Bluetooth module 3002 to be in the connectable state in response to the triggering operation on the application Bluetooth switch comprises:

[0430] In the case that the application Bluetooth switch is in the off state, the controlling the Bluetooth module 3002 to remain in the connectable state or to switch from the unconnectable state to the connectable state in response to the turning-on operation on the application Bluetooth switch.

[0431] The switch state of the application Bluetooth switch comprises a switchable off state and a switchable on state. In the case that the application Bluetooth switch is in the off state, the triggering operation on the application Bluetooth switch is as a turning-on operation on the application Bluetooth switch. In the case that the application Bluetooth switch is in the on state, the triggering operation on the application Bluetooth switch is as a turning-off operation on the application Bluetooth switch.

[0432] In some optional embodiments, the application Bluetooth switch is in the off state by default when the first application is opened, and the user can switch the application Bluetooth switch from the off state to the on state by triggering the application Bluetooth switch.

[0433] The application Bluetooth switch displayed on the display page can have two display forms, respectively representing the off state and the on state. In some embodiments, the application Bluetooth switch is displayed in a first display form in the off state, and is displayed in a second display form in the on state. For example, the first display form can be a component of a first color (such as gray), and the second display form can be a component of a second color (such as green or white). For another example, the first display form can be a component on which OFF is displayed, and the second display form can be a component on which ON is displayed. The display forms can be various as long as they can form a contrast to represent different states, which are not limited herein.

[0434] Before the first application is opened, the connection state of the Bluetooth module 3002 of the display device 3000 can be the connectable state or the unconnectable state, which can be determined according to historical Bluetooth settings or operation records. After the turning-on operation of the application Bluetooth switch is performed, the controller 3005 needs to ensure that the Bluetooth module 3002 of the display device 3000 is in the connectable state. Therefore, in the case that the connection state of the Bluetooth module 3002 is the connectable state, the controller 3005 controls the Bluetooth module 3002 to remain in the connectable state. In the case that the connection state of the Bluetooth module 3002 is the unconnectable state, the controller 3005 controls the Bluetooth module 3002 to switch from the unconnectable state to the connectable state.

[0435] In this embodiment, the controller 3005 responds to the turning-on operation of the application Bluetooth switch as a control instruction for the Bluetooth module 3002, thereby realizing linkage with the connection status of the Bluetooth module 3002, ensuring that the Bluetooth module 3002 is in a connectable state, and providing strong protection for the Bluetooth connection between the external Bluetooth device and the display device 3000.

[0436] In some embodiments, the controller 3005 is further configured to: when the application Bluetooth switch is in the on state, in response to a turning off operation on the application Bluetooth switch, control the Bluetooth module 3002 to restore to a default state.

[0437] In some embodiments, the default state of the Bluetooth module 3002 is a non-connectable state. When the application Bluetooth switch is turned off, the controller 3005 will put the Bluetooth module 3002 in the non-connectable state. If the Bluetooth function needs to be turned on, it can be turned on again through the system Bluetooth settings or by turning on the application Bluetooth switch in the first application to reduce the occurrence of unnecessary Bluetooth misconnections.

[0438] Specifically, controller 3005, in response to the opening operation for applying the Bluetooth switch, can record the current connection state of bluetooth module 3002, and after using the connection state of record as the application Bluetooth switch to close, the default state that bluetooth module 3002 should recover.When detecting that the user closes the application Bluetooth switch, controller 3005 can, based on the connection state of record, restore the connection state of bluetooth module 3002 to the connection state before opening the application Bluetooth switch.For example, before opening the application Bluetooth switch, the connection state of bluetooth module 3002 is a connectable state, then after closing the application Bluetooth switch, the connection state of bluetooth module 3002 still remains a connectable state.For example, before opening the application Bluetooth switch, the connection state of bluetooth module 3002 is a non-connectable state, then after closing the application Bluetooth switch, the connection state of bluetooth module 3002 is restored to a non-connectable state.

[0439] In this embodiment, when the application Bluetooth switch is controlled to be turned off by the controller 3005, the connection status of the Bluetooth module 3002 can effectively reduce the impact of the opening and closing of the Bluetooth switch in the first application on the connection status of the Bluetooth module 3002, and realize that after entering the first application, the Bluetooth module 3002 is controlled separately, and after exiting the first application, the original connection status of the Bluetooth module 3002 is not affected, which conforms to the user's interaction habits and can effectively improve the user experience.

[0440] In some embodiments, the system setting options of the display device 3000 include a system Bluetooth setting option. The system setting option can be displayed in the system menu bar, and the user can use the setting button or other designated button on the remote control device to call up the system setting options of the display device 3000. The system setting options include a system Bluetooth setting option, and the user can use the system Bluetooth setting option to set parameters such as the connection status of the Bluetooth module 3002.

[0441] In some embodiments, the controller 3005 is configured to: in response to the application Bluetooth switch being switched from an off state to an on state, control the system Bluetooth setting option to be switched from a triggerable state to a non-triggerable state.

[0442] In some other embodiments, the controller 3005 is configured to: in response to the application Bluetooth switch being switched from an on state to an off state, control the system Bluetooth setting option to switch from a non-triggerable state to a triggerable state.

[0443] Among them, the triggerable state of the system Bluetooth setting option means that the user can trigger the option to perform corresponding trigger control or parameter setting, and the non-triggerable state means that the user cannot select the option and cannot perform corresponding trigger control or parameter setting for the option.

[0444] In some optional embodiments, the system setting options of the display device 3000 can be displayed in sequence. When the application Bluetooth switch is in the off state, the system Bluetooth setting option is in the triggerable state. The user can use a remote control device or other input method to control the selection of the system Bluetooth setting option and set the system Bluetooth.

[0445] After the application Bluetooth switch is switched from off to on, if the user opens the system settings again without exiting the first application, in some embodiments, the system Bluetooth settings option may be displayed in the system settings option, but the user cannot select the system Bluetooth settings option. In other embodiments, the system Bluetooth settings option can be directly hidden in the system settings option. In this way, it is possible to prioritize the Bluetooth connection when the first application is opened to prevent the connection of the external Bluetooth device from being interrupted due to misoperation.

[0446] After the application Bluetooth switch is switched from the on state to the off state or after the first application is exited, the controller 3005 controls the system Bluetooth setting option to switch from the untriggerable state to the triggerable state. For example, if the untriggerable state is a case where the system Bluetooth setting option is displayed but cannot be selected, the controller 3005 continues to display the system Bluetooth setting option and configures it to be in the selectable state. For another example, if the untriggerable state is a case where the system Bluetooth setting option is hidden, the controller 3005 controls the system Bluetooth setting option to continue to be displayed in the system setting option.

[0447] In this embodiment, when the first application is opened, the configuration permission of the system Bluetooth is opened to the application Bluetooth switch of the first application, and the system Bluetooth setting option in the system setting is set to the untriggerable state, which can give priority to the control of the first application on the Bluetooth, reduces the misoperation caused by the simultaneous opening of multiple Bluetooth setting entrances, and at the same time can simplify the judgment logic of the controller 3005 and reduce the occupation of data processing resources.

[0448] In some embodiments, the display device 3000 is configured with a shielding switch, and when the first audio sent by the external Bluetooth device is received through the Bluetooth module 3002, the controller 3005 controls the shielding switch to be turned on.

[0449] The shielding switch is used to shield at least part of the Bluetooth connection request of the external Bluetooth device. In some embodiments, in response to the user opening the application Bluetooth switch, if the shielding switch is in the off state when the external Bluetooth device is playing, the controller 3005 forcibly turns on the shielding switch to turn on the device shielding function, so that the Bluetooth module 3002 of the display device 3000 is in a connectable state, but at the same time cannot be discovered by other external Bluetooth devices, so as to avoid the interference of other external Bluetooth devices on the external Bluetooth device.

[0450] Correspondingly, in order to avoid affecting the overall performance of the display device 3000, if the application Bluetooth function is not used, such as closing the first application to exit the first mode or disconnecting the connection with the connected external Bluetooth device, the shielding switch is restored to the default state. If the default state of the shielding switch is on, the shielding switch is kept on. If the default state of the shielding switch is off, the shielding switch is turned off again.

[0451] In this embodiment, by configuring the shielding switch, the effective connection of the external Bluetooth device currently sending the audio can be ensured, the access of other external Bluetooth devices is reduced, the interference on the display device 3000 playing the first audio and displaying the artistic paintings is reduced, and the user experience is optimized.

[0452] In some other embodiments, the display device 3000 stores a device whitelist corresponding to the shielding switch; the shielding switch is used to shield Bluetooth connection requests from external Bluetooth devices that are not currently connected to the display device 3000 and are not in the device whitelist.

[0453] Among them, the device whitelist is a setting that allows specific devices to access the service or the device list of connected devices without restriction. Each device in the device whitelist can be regarded as a trusted device. In some embodiments, the controller 3005 can manage the external Bluetooth devices that can establish a connection with the display device 3000 through the device whitelist. The external Bluetooth devices that are not on the device whitelist are external Bluetooth devices that cannot establish a Bluetooth connection with the display device 3000 after the shielding switch is turned on. Among them, the external Bluetooth devices in the device whitelist can be dynamically adjusted according to the user's settings. For example, the user can configure the external Bluetooth devices with historical Bluetooth connection records to be automatically added to the device whitelist. For another example, the user manually specifies some external Bluetooth devices to be added to the device whitelist.

[0454] In some embodiments, the display device 3000 stores a device blacklist corresponding to the shielding switch; the shielding switch is used to shield Bluetooth connection requests from external Bluetooth devices that are not currently connected to the display device 3000 and are in the device blacklist.

[0455] The device blacklist is a list of devices that are not allowed to access services or connect to devices. By blocking communications or activities related to the blacklist, the network and system are protected from potential threats. In some embodiments, the controller 3005 can use the device blacklist to manage external Bluetooth devices that are not allowed to establish a connection with the display device 3000. External Bluetooth devices on the device blacklist are external Bluetooth devices that cannot establish a Bluetooth connection with the display device 3000 after the blocking switch is turned on. The Bluetooth devices on the blacklist can be dynamically adjusted based on user settings.

[0456] In some optional embodiments, the display device 3000 can write a whitelist or blacklist of external Bluetooth devices in a configuration file in response to user configuration. When the controller 3005 receives the first audio sent by the external Bluetooth device, that is, Bluetooth communication has been established with a certain external Bluetooth device, if it receives a pairing request or connection request from other external Bluetooth devices, it reads the device whitelist or device blacklist in the configuration file to determine whether to call the device shielding service based on the device whitelist or device blacklist. If the external Bluetooth device meets at least one condition of being in the device blacklist or not in the device whitelist, the pairing request or connection request of the external Bluetooth device is rejected or not responded to; otherwise, the pairing request or connection request of the external Bluetooth device is responded to normally.

[0457] In this embodiment, whether to block the Bluetooth connection request of the external Bluetooth device is determined by the device blacklist or device whitelist corresponding to the blocking switch, so that the external Bluetooth device allowed by the user can be connected normally, and the external Bluetooth device not allowed by the user will not be connected. The connection can be ensured that the first audio sent by the connected external Bluetooth device can be played normally.

[0458] In some embodiments, when at least one external Bluetooth device establishes a Bluetooth connection with the display device 3000, displaying device information of the external Bluetooth device on the display page includes:

[0459] In response to the triggering operation of the Bluetooth switch of the application, Bluetooth connection guidance information is displayed on the display page of the first application; when the external Bluetooth device requests to establish a Bluetooth connection with the display device 3000 for the first time according to the Bluetooth connection guidance information, pairing confirmation information for the external Bluetooth device is displayed on the display page; in response to the pairing confirmation operation triggered by the pairing confirmation information, a Bluetooth connection with the external Bluetooth device is established, and the device information of the external Bluetooth device is displayed on the display page.

[0460] The Bluetooth connection guidance information is guidance information for guiding the user to perform Bluetooth pairing operations, and can specifically be an example animation of Bluetooth pairing operations, so that the user can follow the example animation to understand how to perform Bluetooth pairing on the external Bluetooth device with the display device 3000.

[0461] The display method of the Bluetooth connection guidance information in the first application can be pre-configured. For example, the Bluetooth connection guidance information can be displayed in a pop-up window or floating layer, so that the user can perform Bluetooth configuration operations while viewing the content such as art paintings displayed in the first application.

[0462] The user can perform pairing operations on the external Bluetooth device according to the Bluetooth connection guidance information. When the external Bluetooth device requests to establish a Bluetooth connection with the display device 3000 for the first time, the pairing confirmation information for the external Bluetooth device will be displayed on the display page, so that the confirmation of the corresponding user of the display device 3000 is obtained when the Bluetooth pairing is established for the first time, so as to realize the connection permission of the external Bluetooth device and prevent the erroneous connection or malicious connection of other external Bluetooth devices.

[0463] The controller 3005 establishes a Bluetooth connection with the external Bluetooth device in response to a pairing confirmation operation triggered by the user in response to the pairing confirmation information. The pairing confirmation operation can be implemented in a variety of ways, such as by pressing a confirmation button on a remote control of the display device 3000 or by voice inputting a confirmation or consent instruction, which are not limited herein.

[0464] After the display device 3000 establishes a Bluetooth connection with the external Bluetooth device, the device information of the external Bluetooth device is displayed on the display page to indicate that the external Bluetooth device has successfully established a Bluetooth connection with the display device 3000. By displaying the device information of the external Bluetooth device, the user can intuitively and promptly know whether the external Bluetooth device has successfully established a Bluetooth connection with the display device 3000.

[0465] In this embodiment, by displaying Bluetooth connection guidance information on the display page of the first application to guide the user to operate the external Bluetooth device to establish a Bluetooth connection, it can effectively guide the user to perform operations, reduce the difficulty of user operation, and is suitable for inexperienced users, effectively improving the user experience.

[0466] In one embodiment, in response to the triggering operation of the Bluetooth switch of the application, displaying Bluetooth connection guidance information on the display page of the first application includes: in response to the triggering operation of the Bluetooth switch of the application, switching the display page of the first application from the content display page to the prompt page built into the first application; displaying Bluetooth connection guidance information on the prompt page.

[0467] The prompt page displays Bluetooth connection guidance information in the form of a page. The prompt page can be a preset page built into the first application. The prompt page contains multiple components, which can be specifically divided into a first-category component with fixed content and a second-category component with variable content. For example, the content in the Bluetooth connection guidance information that instructs the user on how to perform Bluetooth connection operations is the component content of the first-category component with fixed content. Another example is the Bluetooth pairing password generated in real time, which is the component content of the second-category component with variable content.

[0468] In some embodiments, the display device 3000 may display a prompt page including first guidance information for performing a Bluetooth connection operation with the display device 3000. The first guidance information may include the device name of the display device 3000 to accurately indicate the Bluetooth device to be paired, thereby facilitating the user to quickly and accurately connect to the display device 3000.

[0469] The prompt page may include a first guide message. If the device name of the display device 3000 is "Master Bedroom TV", the first guide message may be "Turn on the Bluetooth switch, select Master Bedroom TV for pairing and connection".

[0470] When the display device 3000 is paired with the first Bluetooth device for the first time, a pairing confirmation message will be displayed to ask the user whether to confirm pairing with the first Bluetooth device, which can further ensure the data security of the display device 3000.

[0471] When the display device 3000 is not paired with the first Bluetooth device for the first time, in response to the pairing request of the first Bluetooth device, the display device 3000 directly pairs with the first Bluetooth device and establishes a connection without displaying the pairing confirmation information.

[0472] The pairing confirmation message may include a prompt indicating the name of the first Bluetooth device currently being paired, such as "my phone." In some embodiments, during the pairing process, the display device 3000 may send a pairing password to the first Bluetooth device to further ensure the accuracy and security of the pairing. The pairing page also includes a Pair button and a Cancel button. If the user agrees to pair with the first Bluetooth device, the user may select the Pair button. If the user disagrees with the first Bluetooth device, the user may select the Cancel button.

[0473] For example, a user wants to use the first Bluetooth device to provide audio data to the display device 3000. The first Bluetooth device can be a smart phone, tablet computer, computer, smart TV, etc. The user can perform a Bluetooth connection operation with the display device 3000 on the first Bluetooth device according to the first guidance information in the prompt page.

[0474] In some embodiments, the controller 3005 is further configured to switch the display page of the first application from the prompt page to the content display page when the display time of the prompt page reaches a first preset time and no Bluetooth connection request sent by the external Bluetooth device is received.

[0475] In some optional embodiments, after the prompt page is displayed for a first preset duration, the display device 3000 automatically exits the prompt page and displays the content display page of the first application. For example, if the first preset duration is 10 seconds, the display device 3000 automatically exits the prompt page after displaying the prompt page for 10 seconds.

[0476] In some optional embodiments, the controller 3005 exits the prompt page in response to a return instruction input by the user and displays the content display page of the first application. For example, the user can input a return instruction using the back key of the remote control device, and the display device 3000 exits the prompt page in response to the return instruction.

[0477] In some optional embodiments, the display device 3000 may display a prompt message in the prompt page, and the prompt message is used to prompt the user that the page will automatically jump to the display page after the first time period, and the user can exit the prompt page by pressing the return key.

[0478] In this embodiment, after turning on the application Bluetooth switch in the first application, a prompt page is displayed to allow the user to quickly and conveniently understand how to establish a Bluetooth connection with the display device 3000, and the prompt page is displayed for no longer than a first preset time. After receiving a Bluetooth connection request sent by an external Bluetooth device or the display time reaches the first preset time, the prompt page will be switched back to the content display page to reduce the impact on the display of content such as art paintings.

[0479] In some embodiments, the controller 3005 is further configured to display a device identification of the external Bluetooth device on the display page when receiving the first audio sent by the external Bluetooth device.

[0480] Among them, the device identification of the external Bluetooth device can be a combination of one or more of the device model, device icon, and device name of the external Bluetooth device. The device identification of the external Bluetooth device can facilitate the user to distinguish the current one. The device identification of the external Bluetooth device can be displayed in the upper right corner of the display page of the first application, or displayed in other preset positions on the display page. The display transparency, display color, and display size of the device identification of the external Bluetooth device can be determined based on pre-configured parameters, or can be adaptively adjusted based on the content displayed on the display page to achieve the distinction between the device identification and the display content of the display page.

[0481] In some embodiments, while the external Bluetooth device is sending the first audio, the device identification of the external Bluetooth device may be continuously displayed on the display page, so that the user can identify the source of the currently playing audio from the displayed device identification.

[0482] In some other embodiments, when the display time of the device logo on the display page reaches a second preset time, the device logo is hidden.

[0483] On the one hand, it allows users to understand the source of the currently playing audio when the device logo is displayed. On the other hand, the processing method of first displaying and then hiding the device logo can also enable users to better watch or appreciate the content on the display page in the future, reduce the interference of other display elements, and improve the user experience.

[0484] In some embodiments, receiving the first audio signal sent by the external Bluetooth device through the Bluetooth module 3002 and playing the first audio signal through the audio output module 3001 includes:

[0485] When the currently playing content in the first application is audio and video content, in response to receiving the first audio sent by the external Bluetooth device through the Bluetooth module 3002, the playback audio source played by the audio output module 3001 is switched from the second audio in the audio and video content to the first audio.

[0486] The content played by the display device 3000 is picture content, video content, or audio and video content, and can be played according to the user's input operation or needs.

[0487] In the case that the content currently played by the display device 3000 does not contain audio, the Bluetooth module 3002 receives the first audio sent by the external Bluetooth device, and the audio output module 3001 will play the first audio.

[0488] When the content currently played by the display device 3000 already contains the second audio, after the Bluetooth module 3002 receives the first audio sent by the external Bluetooth device, the audio output module 3001 will switch the playback audio source from the second audio to the first audio, thereby realizing quick and convenient switching of the audio source.

[0489] In some embodiments, the controller 3005 is further configured to: play the second audio through the audio output module 3001 when the external Bluetooth device pauses playing the first audio.

[0490] In some embodiments, the controller 3005 is further configured to: in response to a Bluetooth disconnection event between the external Bluetooth device and the display device 3000 , play the second audio through the audio output module 3001 .

[0491] Specifically, in some embodiments, when a requirement for synchronized playback of audio and video is pre-set for the audio and video content, if it is detected that the external Bluetooth device disconnects the Bluetooth connection or stops sending the first audio to the display device 3000, the controller 3005 can locate the synchronization time node of the second audio in the audio and video content based on the playback progress of the video in the currently playing content, and control the audio output module 3001 to continue playing the second audio in the audio and video content according to the synchronization time node to maintain synchronized playback of audio and video.

[0492] In some other embodiments, when the audio and video content is an independent video and an independent audio, that is, when the video and audio are not required to be played synchronously, when the Bluetooth module 3002 receives the first audio sent by the external Bluetooth device, the controller 3005 will control the pause of the playback of the second audio in the audio and video content and record the playback progress. After detecting that the external Bluetooth device disconnects the Bluetooth connection or stops sending the first audio to the display device 3000, the audio output module 3001 is controlled to continue playing the second audio in the audio and video content according to the playback progress, without affecting the complete playback of the second audio in the audio and video content.

[0493] In this embodiment, by switching the audio source played by the audio output module 3001, the audio content can be adjusted and the second audio can be switched to the first audio, so that the user can hear the first audio played by the external Bluetooth device while watching the video played by the first application, which can maximize the satisfaction of user requirements and enhance the user experience.

[0494] In some embodiments, the controller 3005 is further configured to: when the first audio is played through the audio output module 3001, display at least one of a mute status identifier matching the currently playing content and a play status identifier matching the first audio on the display page of the first application.

[0495] In the process of displaying the screen content on the display page of the first application, when it involves switching the audio source, in order to facilitate the user to understand the source of the currently playing audio, the display page can display a first identifier corresponding to the currently playing content and a second identifier representing the external Bluetooth device or the first audio.

[0496] When the audio output module 3001 plays the first audio, the display page can display a mute status indicator for the first identifier, or a play status indicator for the second identifier. The mute status indicator for the first identifier and the play status indicator for the second identifier can also be displayed at the same time, so that the user can understand the source of the currently playing audio through the indicator in the display page.

[0497] At least one of the mute state identifier matched with the currently played content and the playing state identifier matched with the first audio can be hidden after a third preset time length, so as to reduce the interference on the display device 3000 in displaying the content in the display page of the first application, and further enhance the immersive experience of the user.

[0498] In the embodiment, when the audio output module 3001 plays the first audio, at least one of the mute state identifier matched with the currently played content and the playing state identifier matched with the first audio is displayed, so that the user can intuitively understand the source of the currently played audio through the identifier in the display page without checking the external Bluetooth device, and the operation required by the user to confirm the source of the currently played audio is simplified.

[0499] In some embodiments, the controller 3005 is further configured to disconnect the Bluetooth connection between the display device 3000 and the external Bluetooth device in response to an exit operation of exiting the first application.

[0500] Since the external Bluetooth device establishes the connection with the display device 3000 when the first application is opened, after the first application is exited, the Bluetooth connection between the display device 3000 and the external Bluetooth device needs to be disconnected, so that the audio played by other applications in the display device 3000 during use is not affected.

[0501] In some embodiments, the controller 3005 can control the application Bluetooth switch to be in the off state and disconnect the Bluetooth connection between the display device 3000 and the external Bluetooth device in response to the exit operation of exiting the first application, so that the display device 3000 can quickly respond to the exit operation of the user.

[0502] In some other embodiments, the controller 3005 can send a pause playing instruction to the external Bluetooth device in response to the exit operation of exiting the first application, and send a continue playing instruction to the external Bluetooth device in response to an opening operation of opening the first application again if the first application is opened within a third preset time length after the first application is exited, so that the cumbersome operation of opening the application Bluetooth switch and performing Bluetooth connection again when the user reenters the first application after the exit of the first application due to the misoperation of the user can be overcome.

[0503] Further, in some optional embodiments, the controller 3005 controls the application Bluetooth switch to be in the off state and disconnects the Bluetooth connection between the display device 3000 and the external Bluetooth device if no opening operation of the first application is detected by the controller 3005 after the third preset time length after the first application is exited.

[0504] In other optional embodiments, after the user exits the first application, it can also be determined whether it is necessary to control the application Bluetooth switch to be in the off state based on the number of operation instructions entered by the user, and disconnect the Bluetooth connection between the display device 3000 and the external Bluetooth device.

[0505] For example, if the user inputs the operation instruction of switching the display page three times, it can be considered that the user wants to watch other content, and the Bluetooth connection between the display device 3000 and the external Bluetooth device is directly disconnected.

[0506] For another example, the controller 3005 can also determine whether the user may have made an incorrect operation based on the number of repeated inputs of the same input instruction. If the user inputs the operation instruction to switch the display page three times, but these three operation instructions are triggered by the same button on the remote control device, it is possible that the user accidentally presses the button of the remote control device to issue the input instruction. At this time, after the third preset time after exiting the first application, if no operation to open the first application is detected, the application Bluetooth switch can be controlled to be in the off state, and the Bluetooth connection between the display device 3000 and the external Bluetooth device can be disconnected.

[0507] In this embodiment, it is possible to fully consider whether the user may make an erroneous operation. By disconnecting the Bluetooth connection between the display device 3000 and the external Bluetooth device when exiting the first application, the user experience is that the audio playback of the external Bluetooth device has ended. However, if the user confirms that the exit was an erroneous operation, opening the first application again within the third preset time period after exiting the first application can enable the external Bluetooth device to continue to send the first audio without the user having to interact multiple times to reconnect the Bluetooth, which simplifies the user's operation and can effectively improve the user experience.

[0508] In one embodiment, the device identification displayed on the display page includes at least a first device identification and a second device identification, wherein the first device identification is used to identify a first external Bluetooth device that plays the first audio; and the second device identification is used to identify a second external Bluetooth device that has established a Bluetooth connection with the display device 3000.

[0509] The controller 3005 is also configured to: when the first audio is played through the audio output module 3001, in response to a selection operation for the second device identifier, pause playing the first audio; receive the third audio played by the second external Bluetooth device through the Bluetooth module 3002, and play the third audio through the audio output module 3001.

[0510] The display device 3000 can simultaneously establish connections with multiple external Bluetooth devices. In some embodiments, after the Bluetooth module 3002 of the display device 3000 is in a connectable state, it can be discovered by other external Bluetooth devices. The display device 3000 can respond to a pairing request from an external Bluetooth device and, if the user agrees to the pairing, pair with the other external Bluetooth device and establish a connection.

[0511] In some embodiments, if the external Bluetooth device is a device that has established a connection with the display device 3000 and is within the Bluetooth communication range, the display device 3000 can respond to the user's operation of turning on the application Bluetooth switch, display a list of paired devices in the first application, and respond to the user's instruction to select one of the external Bluetooth devices from it, establish a connection with the selected external Bluetooth device.

[0512] In some embodiments, when the display device 3000 is simultaneously connected to multiple external Bluetooth devices, one external Bluetooth device can be selected to provide audio. A specific implementation method may be: upon receiving a first audio signal sent by a first Bluetooth device, in response to a user's control instruction, a list of connected devices is displayed. In response to a user's instruction to select a second Bluetooth device, reception of the first audio signal from the first Bluetooth device is terminated, and reception of audio signal from the second Bluetooth device is started. After receiving a third audio signal from the second Bluetooth device, the third audio signal is played.

[0513] In this embodiment, when the display device 3000 switches the audio source device to the second Bluetooth device, the second Bluetooth device can be in the audio playback state, the audio pause state, or the audio stop state. If the user opens a music application on the second Bluetooth device and plays a third audio, the third audio can be sent to the display device 3000. After receiving the third audio, the display device 3000 plays the third audio. This is a quick operation to switch audio sources between different external Bluetooth devices, which improves the convenience of operation.

[0514] In some embodiments, after the display device 3000 recognizes that the second Bluetooth device is in an audio playback state, it can display the device 3000 playback information on the display page. The device playback information may include the device name and device icon of the second Bluetooth device, and the device icon is used to identify the device type of the second Bluetooth device. Furthermore, after a preset time period, the device playback information is hidden. The process of displaying and hiding the device playback information can refer to the process of displaying and hiding the device playback information of the first Bluetooth device, and is not repeated here.

[0515] In some embodiments, the display device 3000 may be configured to unmute the third audio upon detecting that the currently used external Bluetooth device has paused audio playback, or upon detecting that the currently used external Bluetooth device is disconnected. Disconnecting from the currently used external Bluetooth device may include disconnecting the currently used external Bluetooth device from the display device 3000, or the display device 3000 exiting the first application, etc.

[0516] Based on this, taking the case where the display device starts up and opens the first application APP A to display the display interface of the first application as an example, during the processing of the display device, the timing diagram of the interaction process of the relevant modules in the display device is as follows: Figure 31 shown.

[0517] Figure 31 As shown, after launching the first application, APP A, the display device displays the homepage of APP A on the display. In response to a menu-opening instruction to open the built-in application menu of the first application, the display device also displays the application menu. While the application menu is displayed, in response to an instruction to select the BT music menu option in the application menu, the display device launches the Bluetooth connection guide page. While maintaining the Bluetooth connection guide page, the display device can send a Bluetooth switch status acquisition instruction to the Bluetooth switch setting module.

[0518] The Bluetooth switch setting module is an application module used to set and record the status of the Bluetooth switch in the display device. This switch can include the system Bluetooth switch and the application Bluetooth switch, as described above. The Bluetooth switch setting module responds to the Get Bluetooth Switch Status command, queries the current Bluetooth switch status, and returns the current Bluetooth switch status.

[0519] After obtaining the current Bluetooth switch status returned by the Bluetooth switch setting module, if at least one Bluetooth switch is off in the current Bluetooth switch status, a Bluetooth switch turn-on instruction is issued to the Bluetooth switch setting module. In response to the Bluetooth switch turn-on instruction, the Bluetooth switch setting module turns on the off switch, turning on both the system Bluetooth switch and the application Bluetooth switch.

[0520] After the Bluetooth device status and the application Bluetooth switch are turned on, a Bluetooth status broadcast for registering the first application is sent to the Bluetooth module of the Framework layer. The Bluetooth module receives the Bluetooth status broadcast and registers the first application to indicate that the first application uses the Bluetooth function.

[0521] After the Bluetooth device status and application Bluetooth switch are turned on, an instruction to turn on the SINK mode is also sent to the Bluetooth module of the Framework layer. After receiving the instruction to turn on the SINK mode, the Bluetooth module forwards it to the Bluetooth driver module of the driver layer. The Bluetooth driver module turns on the Bluetooth SINK mode and sends broadcasts regularly. The broadcast information may include the device name, MAC address, and SINK mode information of the display device.

[0522] When an external Bluetooth device (such as a mobile phone, tablet computer, etc.) receives the broadcast information and selects the display device for connection, it sends a Bluetooth connection request to the Bluetooth driver module of the TV module.

[0523] After receiving the Bluetooth connection request, the Bluetooth driver module forwards it to the Framework layer's Bluetooth module. The Bluetooth module confirms and establishes a Bluetooth connection with the external Bluetooth device. After the connection is successful, it broadcasts a successful Bluetooth connection to the first application. After receiving the successful Bluetooth connection broadcast, the first application displays a successful connection message and may also display the device name of the connected external Bluetooth device.

[0524] After the display device establishes a Bluetooth connection with an external Bluetooth device in SINK mode, the external Bluetooth device can play audio (such as music) and send A2DP protocol transmission instructions to the display device. The display device's Bluetooth driver module receives the A2DP protocol transmission instructions, receives the audio stream transmitted by the external Bluetooth device, and transmits it to the Bluetooth module at the framework layer. The Bluetooth module receives the audio stream and plays it. After the audio stream is played, a playback success broadcast can be sent to inform the first application that the audio from the external Bluetooth device has been successfully played.

[0525] The display device receives the broadcast of successful playback and obtains the current playback status of the display device. If a local video is playing, the audio of the local video is paused. In other words, the audio of the local video is not played, but the audio received from the external Bluetooth device is played.

[0526] While the external Bluetooth device continues to play audio, the above process of the external Bluetooth device sending the audio stream, the Bluetooth driver module receiving the audio stream and the Bluetooth module playing the audio stream can be continuously performed.

[0527] When the external Bluetooth device is continuously playing audio, if a pause playback command is received, the external Bluetooth device will pause the music and can send a pause status command to the display device via the Bluetooth protocol transmission command.

[0528] The Bluetooth driver module of the display device receives the pause state instruction and transmits it to the Bluetooth module. The Bluetooth module pauses the playback based on the pause state instruction and performs playback pause broadcast.

[0529] The first application receives the playback pause broadcast, obtains the playback status, and if there is a local video playing, resumes the audio playback of the local video, that is, plays the audio of the local video.

[0530] If an instruction to exit the first application is received, the system Bluetooth switch interface of the Bluetooth switch module is called to restore the Bluetooth switch state, that is, to set the system Bluetooth switch to off, and send a command to turn off the sink mode to the Bluetooth module, and unregister the Bluetooth status broadcast. After receiving the command to turn off the sink mode, the Bluetooth module forwards it to the Bluetooth driver module, which turns off the sink mode and turns on the source mode, disconnecting the Bluetooth connection with the external Bluetooth device.

[0531] refer to Figure 32 As shown, the display device 3000 in some embodiments may further include a light sensor 3006 , and the controller 3005 is communicatively connected with the audio output module 3001 , the Bluetooth module 3002 , the display 3004 and the light sensor 3006 .

[0532] The light sensor 3006 is used to detect light intensity. A light sensor is a device that can sense light energy and convert it into an electrical signal, through which the light intensity can be determined. In some embodiments, the light sensor can be an ambient light sensor.

[0533] The controller 3005 is configured to display the application Bluetooth switch and the fourth mode switch built into the first application on the display page of the first application;

[0534] The controller 3005 is further configured to control the Bluetooth module to be in a connectable state in response to a triggering operation on the application Bluetooth switch;

[0535] The controller 3005 is further configured to, when at least one external Bluetooth device establishes a Bluetooth connection with the display device, receive, through the Bluetooth module, a first audio signal sent by the external Bluetooth device, and play the first audio signal through the audio output module;

[0536] The controller 3005 is further configured to control the display device to enter a screen-off and silent state when the fourth mode switch indicates that the fourth mode is on and the light sensing data of the current environment meets the on condition of the fourth mode.

[0537] Through the above-mentioned display device, in the process of establishing a Bluetooth connection between the external Bluetooth device and the display device, the application Bluetooth switch can be triggered directly on the display page of the first application, so that the Bluetooth module of the display device is in a connectable state, and the Bluetooth connection between the external Bluetooth device and the display device can be quickly and easily achieved. The Bluetooth module can receive the first audio sent by the external Bluetooth device, and play the first audio through the audio output module while the display displays the display page. The user's favorite audio is played while the display device displays the content of the display page. Furthermore, the display device can also be turned on in the fourth mode, and enter the screen-off mute state when the light sensing data of the current environment meets the activation conditions of the fourth mode. It can control the working status of the display device in combination with the current environment, and realize intelligent and effective control of displayed content and played audio, thereby improving the user experience.

[0538] In some embodiments, the activation condition of the fourth mode includes at least the ambient light data being less than a preset light data and lasting for a fourth preset duration. The fourth preset duration can be set in any manner and can be determined based on experiments or time requirements for entering / exiting the fourth mode. The fourth preset duration can be set in seconds.

[0539] The fourth mode is an application mode for situations where the display device 3000 is not required to display content or play audio in a dimly lit night environment. This fourth mode may also be referred to as night mode. In night mode, the display device 3000 is in a screen-off and silent state. The light intensity detected by the light sensor 3006 is used as a factor in determining whether to enter and exit night mode. For ease of description, the following embodiments will be described using the fourth mode as night mode.

[0540] In some embodiments, when the light intensity is less than a preset light intensity threshold and the duration for which the light intensity is less than the preset light intensity threshold reaches a first preset duration, it can be considered that the conditions for entering night mode are met, and the display device is controlled to enter night mode.

[0541] In some embodiments, the controller 3005 is further configured to display a prompt interface indicating that the system will enter the night mode after the countdown period ends when the specified conditions for entering the night mode are met.

[0542] The initial duration of the countdown can be the fifth preset duration. When the conditions for entering the night mode are met, the controller 3005 starts the countdown of the fifth preset duration and displays a prompt interface that will enter the night mode after the countdown ends. It can be understood that the duration displayed in the prompt interface gradually decreases as time progresses, and enters the night mode after decreasing to 1 or 0, that is, the display device enters a state of screen-off and silent. Taking the fourth mode as night mode as an example, a 15-second countdown and a prompt message for entering night mode can be displayed in the prompt interface. After the countdown ends, the display device turns off the screen and silent and enters night mode.

[0543] In this embodiment, by displaying a prompt interface that the night mode will be entered after the countdown period ends, the user can be prompted so that the user can actively exit the night mode when the user does not need to enter the night mode, thereby improving the user experience.

[0544] In some embodiments, the controller 3005 is further configured to stop displaying the prompt interface and return to the interface before displaying the prompt interface if an instruction not to enter night mode is received during the process of displaying the prompt interface that will enter night mode after the countdown period ends.

[0545] In some embodiments, the controller 3005 is further configured to enter night mode when the countdown to the fifth preset duration ends. For example, during the process of displaying the prompt interface indicating that the device will enter night mode after the countdown ends, if no instruction to not enter night mode is received before the countdown ends, the device enters night mode.

[0546] In some embodiments, the display device 3000 may also be provided with setting options for night mode, such as a setting option for a preset light intensity threshold, a setting option for a fourth preset time length, a setting option for a fifth preset time length, and the like.

[0547] In this embodiment, the preset light intensity threshold setting option allows customization of the preset light intensity threshold to enable customization and updating of the preset light intensity threshold. The fourth preset duration setting option allows customization of the fourth preset duration to enable customization and updating of the fourth preset duration. The fifth preset duration setting option allows customization of the fifth preset duration to enable customization and updating of the fifth preset duration.

[0548] Among them, the method of entering the setting options of night mode and the display interface of the setting options of night mode are not limited, as long as the customized settings of the preset light intensity threshold, the fourth preset time length and the fifth preset time length can be achieved.

[0549] In some embodiments, the controller 3005 is further configured to control the display device to restore a historical playing state before the display device enters the screen-off mute state, in a case that the display device enters the screen-off mute state and the current environment satisfies the closing condition of the night mode.

[0550] In some embodiments, after the display 3004 is turned on in the case that the night mode is exited, the interface displayed by the display 3004 can be the historical playing state before the display device enters the screen-off mute state, such as the interface of the application displayed before the night mode is entered.

[0551] In the case that the night mode is exited, the audio output module 3001 plays audio, which means that the audio output module 3001 is in a state capable of playing audio. When the audio output module 3001 plays audio after the night mode is exited, the audio played can be audio received from an external Bluetooth device through the Bluetooth module, or can be audio played locally by the display device 3000.

[0552] In the case that the night mode is exited, the audio output module 3001 plays audio, which means that the audio output module 3001 is in a state capable of playing audio. When the audio output module 3001 plays audio after the night mode is exited, the audio played can be audio received from an external Bluetooth device through the Bluetooth module, or can be audio played locally by the display device 3000.

[0553] In the case that the night mode is exited, the display 3004 is turned on, and the audio output module 3001 plays audio.

[0554] In the case that the night mode is exited, the display 3004 is turned on, and the audio output module 3001 plays audio.

[0555] In the case that the night mode is exited, the display 3004 is turned on, and the audio output module 3001 plays audio.

[0556] In some embodiments, the controller 3005 is further configured to control the display device to restore a historical playing state before the display device enters the screen-off mute state, in a case that the display device enters the screen-off mute state and the current environment satisfies the closing condition of the night mode.

[0557] In some embodiments, after the display 3004 is turned on in the case that the night mode is exited, the interface displayed by the display 3004 can be the historical playing state before the display device enters the screen-off mute state, such as the interface of the application displayed before the night mode is entered.

[0558] Among them, in some embodiments, taking the example that the audio output module 3001 plays the audio received by the Bluetooth module from the external Bluetooth device before exiting the night mode, when in night mode, if the distance between the external Bluetooth device and the display device 3000 continues to be within the Bluetooth connection range, the display device 3000 can maintain the Bluetooth connection with the external Bluetooth device in audio receiving mode, and after exiting the night mode, the audio received from the external Bluetooth device through the Bluetooth module can be played.

[0559] In some embodiments, taking the example of the case where the audio output module 3001 plays audio received by the Bluetooth module from an external Bluetooth device before exiting night mode, the external Bluetooth device can actively disconnect the Bluetooth connection with the display device 3000 when in night mode. Alternatively, if the distance between the external Bluetooth device and the display device 3000 exceeds the Bluetooth connection range, the Bluetooth connection between the external Bluetooth device and the display device 3000 will also be disconnected. After exiting night mode, the display device 3000 can, based on the state before exiting night mode, establish a connection in audio reception mode with the external Bluetooth device within the Bluetooth connection range and play the audio received from the external Bluetooth device via the Bluetooth module.

[0560] In this embodiment, when the night mode is turned off, the display device is controlled to enter the default state, and the current process can be directly ended without the user triggering an interactive operation, making it easier for the user to open other applications or enter other modes, thereby improving the user experience.

[0561] In some embodiments, the controller is further configured to send a pause playback instruction to the external Bluetooth device when the night mode switch indicates that the night mode is on and the current environment meets the on conditions of the night mode, and to send a continue playback instruction to the external Bluetooth device when the display device enters the screen-off and silent state and the previous environment meets the off conditions of the night mode.

[0562] In this embodiment, when the night mode is turned on, the control display device sends a pause playback instruction to the external Bluetooth device. When the night mode is turned on, the control display device sends a pause playback instruction to the external Bluetooth device, which can facilitate the user to continue to watch the audio played before the screen is turned off and the sound is muted when exiting the night mode, ensuring that the audio played before entering the night mode and after exiting the night mode can be connected, avoiding the user from missing important audio content, and improving the user experience.

[0563] In some embodiments, for example, before exiting night mode, the audio output module 3001 plays audio received by the Bluetooth module from an external Bluetooth device. While in night mode, the external Bluetooth device can proactively disconnect from the display device 3000. Alternatively, if the distance between the external Bluetooth device and the display device 3000 exceeds the Bluetooth connection range, the Bluetooth connection between the external Bluetooth device and the display device 3000 will also be disconnected. After exiting night mode, the display device 3000 can directly play the local audio on the display device. Alternatively, if no external Bluetooth device is within the Bluetooth connection range, the local audio on the display device can be played.

[0564] In some embodiments, taking the example that the audio output module 3001 plays the local audio of the display device 3000 before exiting the night mode, after exiting the night mode, the audio output module 3001 can directly play the local audio of the display device 3000.

[0565] In some embodiments, after exiting the night mode, the audio output module 3001 may first play a prompt tone for exiting the night mode, and then play the audio received from the external Bluetooth device through the Bluetooth module, or the local audio of the display device 3000.

[0566] The preset light intensity threshold can be set in any manner and can be determined based on experiments or sensitivity to entering night mode. The preset light intensity threshold can be configured in the display device 3000. The controller 3005 obtains the light intensity detected by the light sensor 3006 and compares the light intensity with the configured preset light intensity threshold.

[0567] Based on this, taking the display device as an example, after the first application is opened and the first mode is entered, during the processing of the display device, the timing diagram of the interaction process of the relevant modules in the display device is as follows: Figure 33 shown.

[0568] like Figure 33As shown, a night mode switch is set in the application menu built into the first application of the display device. The user can control the on / off state of the night mode switch through input operations. The first mode service configured for the first application can determine whether the night mode switch is turned on. If the night mode switch is turned on, the controller can control the light sensor to read and collect the light intensity of the environment, and feed back the collected light intensity to the first mode service. The first mode service further determines whether the collected light intensity is lower than the preset ambient light. When the collected light intensity is lower than the preset ambient light and the duration reaches 10 seconds, a mute command is generated and sent to the audio management service of the Framework layer, and through the interaction with the wake-up lock service and the power management service of the Framework layer, the display device is controlled to enter the screen-off mute state. After the display device enters the screen-off mute state, the display device sends a pause command to the external Bluetooth device, and the external Bluetooth device no longer sends the first audio to the display device.

[0569] During this period, the light sensor will continuously read and collect the ambient light intensity, and feed the continuously collected light intensity back to the first mode service. The first mode service further determines whether the collected light intensity is higher than the preset ambient light. If the collected light intensity is higher than the preset ambient light and the duration reaches 10 seconds, it generates an unmute command and sends it to the audio management service of the Framework layer. Through interaction with the wake-up lock service and power management service of the Framework layer, it controls the display device to unmute the screen. After the display device unmutes the screen, the display device sends a play command to the external Bluetooth device, and the external Bluetooth device continues to send the first audio to the display device.
