[0090] 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.

[0091] Usually, users mainly use display devices as devices with audio and video playback functions. In order to more fully develop the use value of the display device, a first application can be configured for the display device to provide a first mode through the first application. Among them, the first application is at least used to play pictures, and the first application can also be called an art application, an art mode (Art Mode) application, a gallery (Gallery) application, a picture frame (Frame) application, etc. The first mode can also be called art mode, gallery mode, picture frame mode, etc. In the first mode, the display device can display art paintings as decorations in the space. In addition, by simulating art paintings as real art paintings, users can browse art paintings in an immersive way. For example, adding a display frame to an art painting, installing a hardware frame on the border of the display device, using a paper-like screen as a display screen, etc.

[0092] In the embodiment of the present application, a specific description is given by taking the first application as an art mode application and the first mode as an art mode as an example.

[0093] The display device 200 may enter the art mode in the following manner:

[0094] In some embodiments, the display device 200 may be configured to, in a power-off state, start 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 the art mode after starting the art mode application.

[0095] In some embodiments, the display device 200 can be configured to: in the off state, display the system home page in response to an instruction by the user to long press the power button of the control device 100, and start the art mode application in response to a first instruction input by the user to short press the power button or home button of the control device 100, and enter the art mode after starting the art mode application.

[0096] In some embodiments, the display device 200 may be configured to, in a powered-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 the art mode after launching the art mode application.

[0097] In some embodiments, the display device 200 may be configured to enter the art mode in response to a user selecting an icon of an art mode application when displaying the system homepage. The icon of the art mode application may be configured on the system homepage or in a sidebar of the system homepage.

[0098] 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 key of the control device 100 when the display device 200 is in the power-on state and has not entered the art mode.

[0099] 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 based on an art mode key of the control device 100 when the display device 200 is in the power-on state and has not entered the art mode.

[0100] In some embodiments, if the user turns on the scheduled power-on and sets the power-on time, the display device 200 can be configured to: in the off state, if the system time is monitored to match the power-on time, start the art mode application after powering on, and enter the art mode after starting the art mode application.

[0101] In some embodiments, the control device 100 generates a press signal in response to the user pressing a key, and sends the press signal to the display device 200. The control device 100 also generates a release signal in response to the user lifting the key, and sends the release signal to the display device 200. Accordingly, the display device 200 can determine whether the user performs a short press operation or a long press operation on the key by monitoring the press event and release event of the key. For example, the display device 200 can use the dispatchKeyEvent method to capture the key event, and the captured key event may include a press (KeyEvent.ACTION_DOWN) event and a release (KeyEvent.ACTION_UP) event. When the display device 200 monitors the key event, it detects whether it is the first press. If it is detected that it is the first press, such as event.getRepeatCount()==0, a timer (such as Handler and Runnable) is started, and the timer counts 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, which can determine that the user performs 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 performs a short press operation on the key.

[0102] In other embodiments, the control device 100 responds to the user pressing the key, and until the user lifts the key, the key value signal is periodically sent to the display device 200. The display device 200 can determine whether the user performs a short press operation or a long press operation on the key according to the number of key value signals received, wherein if the number of key value signals received by the display device 200 is less than or equal to the preset number of times, it can be determined that the user performs a short press operation on the key. If the number of key value signals received by the display device 200 is greater than the preset number of times, it can be determined that the user performs a long press operation on the key. For example, the preset number of times is 1, and if the number of key value signals received by the display device 200 is 1, it can be determined that the user performs a short press operation 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 performs a long press operation on the key.

[0103] The display device 200 may be configured with a third application, and the third application may call the application data of the first application running in the background, such as artwork, picture quality parameters, carousel parameters, etc. In this way, after entering the third application, the display device 200 is in the third mode. In the third mode, the display device 200 will display the screen saver page of the third application, and display the artwork provided by the first application on the screen saver page, thereby realizing the display of the various artworks provided by the first application in the form of a screen saver. In the third mode, the user cannot use the relevant functions of the first application, that is, cannot set the artwork, etc.

[0104] 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.

[0105] 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.

[0106] The display device 200 may enter the art screen saver mode in the following manner:

[0107] 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 is detected within a specified time period in a non-physical channel, or no signal input is detected in a currently used physical channel.

[0108] In some embodiments, the signal channel of the display device 200 may include a physical channel and a non-physical channel. Among them, a physical channel refers to a channel that transmits a signal through a physical medium, and the physical medium may be a cable, an optical fiber, a satellite antenna, etc. Physical channels may include TV channels, AV channels, HDMI channels, etc. Non-physical channels refer to channels that transmit signals wirelessly without the need for a physical connection to transmit signals. Signals other than physical channels may be referred to as non-physical channels, and non-physical channels may include: launcher homepage, third-party applications, etc.

[0109] After entering the art mode, the display device 200 displays a presentation page and displays art works on the presentation page.

[0110] In some embodiments, the display page is a user display 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 display interface.

[0111] In some embodiments, when the hardware picture frame is not installed, the display device 200 can add a picture frame with a three-dimensional effect to the art painting in the display page, so as to simulate a real mounting effect through the added picture frame.

[0112] You can refer to Figure 5 The display page shown includes an art work 501 and a picture frame 502 for additional display.

[0113] In other embodiments, a hardware picture frame may be installed on the frame of the display device 200 to simulate a real mounting effect.

[0114] 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.

[0115] 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 sense of immersion.

[0116] 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.

[0117] In some embodiments, the art paintings in the same painting classification can be further divided into different painting classifications. The same painting classification can be called a parent painting classification, and the painting classifications contained therein can be called child painting classifications. In this way, the user can quickly search for art paintings in the same parent painting classification according to different child painting classifications.

[0118] In the embodiment provided in the present application, art paintings are divided into two levels of painting classification, the upper level painting classification is the first level classification, and the lower level painting classification is the second level classification. Among them, the first level classification may include art gallery classification, photo collection classification, immersive atmosphere classification, favorite classification, etc. The second level classification included in the art gallery classification may include landscape classification, character classification, modern classification, still life classification, etc. The second level classification included in the photo collection classification may include my photo classification and photo theme classification. The second level classification included in the immersive atmosphere classification may include the immersive atmosphere classification, and the second level classification included in the favorite classification may include the favorite classification.

[0119] In order to facilitate users to quickly find the art paintings they want to browse according to the classification and classification, the art mode application can be configured with a graded browsing page. The graded 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 form, including preview images of art paintings included in the second-level classification that is selected or focused. In some embodiments, the background of the graded preview page may be transparent. In other embodiments, the background of the graded preview page may be opaque or translucent. In some embodiments, the first menu and the second menu may be translucent, and the transparency is gradually changed. In other embodiments, the first menu and the second menu may be opaque or transparent.

[0120] 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, for description.

[0121] In some embodiments, when displaying a display page, the display device 200 may be configured to: display a hierarchical browsing page on the upper layer of the display page in response to a user's designation based on a confirmation key or an OK key input of the control device 100. The artwork currently displayed in the display page located at the lower layer may be displayed through the hierarchical browsing page.

[0122] You can refer to Figure 7The display effect of the hierarchical preview page shown in the figure, the hierarchical preview page includes a first menu 701 and a second menu 702. The first menu 701 includes titles of primary categories, such as art gallery, photo collection, immersive atmosphere and favorite. Among them, the art gallery is in a selected state. Based on the art gallery being in a selected state, the second menu 702 includes titles of secondary categories included in the art gallery classification, such as landscape, characters, modern, still life and others. Among them, the focus is obtained by the landscape. The second menu 702 also includes a preview image list 703. Based on the focus obtained by the landscape, the preview image list 703 includes preview images of art paintings included in the landscape classification. Such as landscape 14, landscape 15, landscape 16, landscape 17, landscape 18, and corresponding preview images.

[0123] In this embodiment of the present application, for the sake of convenience, the corresponding art paintings are represented by the method of "secondary classification + the order of the pictures in the secondary classification". For example, landscape 16 represents the 16th art painting in the landscape classification.

[0124] The background of the graded preview page is transparent. Figure 7 , the background 704 is transparent. Therefore, the art works currently displayed in the display page, such as three geometric figures, can be displayed through the background 704.

[0125] In some embodiments, the user can select the first-level category and the second-level category that he wants to preview based on the hierarchical preview page to browse the preview images of the corresponding artworks in the preview image list. In addition, the user can exit the hierarchical preview page by selecting a preview image, and quickly switch the artwork displayed in the display page to the artwork corresponding to the selected preview image.

[0126] In some embodiments, in order to facilitate users to preview more preview images at one time to improve the efficiency of finding art paintings, the art mode application can also be configured with a global preview page. The global preview page may include a third menu and a global preview image list, and the third menu includes the titles of the secondary categories included in the target primary classification, wherein the focus is obtained by the title of the target secondary classification. The target primary classification is the primary classification to which the art painting currently displayed in the display page belongs, and the target secondary classification is the secondary classification to which the art painting corresponding to the preview image currently included in the preview image list belongs. The global preview image list is in the form of a grid, including preview images of the art paintings included in the target secondary classification. In this way, the user can browse the preview images of each art painting included in each secondary classification in the target primary classification at one time through the global preview page.

[0127] In some embodiments, when a preview image in the preview image list obtains focus, the display device 200 may be configured to: in response to a downward instruction input by the user based on a downward key of the control device 100 , display a global preview page on an upper layer of the hierarchical preview pages.

[0128] Can Figure 7 In response to the downward instruction of the user, the display device 200 may display the following information on the upper layer of the hierarchical preview page: Figure 8 The global preview page shown. The global preview page includes a third menu 801. The third menu 801 includes titles of secondary categories of the art gallery, such as landscape, figure, modern, still life, and others. Among them, the focus is on landscape. The global preview page also includes a global preview image list 802, which includes preview images of all art paintings included in the landscape category. Taking landscapes 1 to 18 as an example of all art paintings included in the landscape category, the global preview image list 802 includes preview images of landscapes 1 to 18.

[0129] In some embodiments, based on the global preview page, the user can select the secondary category that he wants to preview under the target primary category to browse the preview of the corresponding artwork in the global preview image list. In addition, the user can exit the global preview page and the hierarchical preview page by selecting a preview image, and quickly switch the artwork displayed in the display page to the artwork corresponding to the selected preview image.

[0130] 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 a 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 a menu button for specific description.

[0131] The application settings menu is displayed on the upper layer of the display page, you can refer to Fig. 9 The application setting menu 901 shown 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 effect after setting through the application setting menu.

[0132] In some embodiments, the art mode application may 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 a 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, which can be referred to Fig.10 The Art Mode setting page shown in the figure. In this way, based on the Art Mode setting page, users can set various parameters more centrally.

[0133] In some embodiments, an entry to the art mode settings page may be configured in the application settings menu, such as Fig. 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.

[0134] In some embodiments, the immersive atmosphere classification may include dynamic art paintings with audio, that is, the art paintings included in the immersive atmosphere classification are videos. In this way, when the display device 200 displays the art paintings 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 contained in the art paintings under the immersive atmosphere classification may not be the music that the user likes, which will result in the failure to create the sense of atmosphere that the user likes. In addition, for art paintings under other categories, these art paintings are all pictures, so the display device 200 does not play audio when displaying these art paintings. Then, when the user browses these art paintings, he will lack a sense of atmosphere.

[0135] In order to solve the above problems, the art mode application is configured with an application Bluetooth music function. In this way, in the art mode, the user can use the application Bluetooth music function to connect to the Bluetooth device at any time, and send his favorite audio to the display device 200 through the Bluetooth device to play the audio through the display device 200, thereby creating his favorite atmosphere.

[0136] In some embodiments, reference may be made to Figure 4 The operating system shown in the figure has the first application-related modules configured in the application layer of the operating system, such as the Bluetooth switch module, the connection device management module, the registration monitoring module, the operation guidance module, the playback control module, etc. The Bluetooth music receiving module, the music playback control module, etc. are configured in the framework layer. The Bluetooth communication module, the Bluetooth driver, etc. are configured in the core layer.

[0137] Among them, the Bluetooth switch module is used to display different Bluetooth switches to the user and interact with the user to turn them on and off.

[0138] The connection device management module is used to manage each connected Bluetooth device and can generate and display the corresponding device list.

[0139] Register a monitoring module to monitor the connection status with the Bluetooth device, the audio playback status of the Bluetooth device, etc.

[0140] The operation guide module is used to display the operation guide for pairing with Bluetooth devices and other operations.

[0141] The playback control module is used for audio playback of the entire machine.

[0142] The Bluetooth music receiving module, as a Bluetooth receiving end of the display device 200, can receive Bluetooth music signals from a Bluetooth device.

[0143] The music playback control module is used to call the system's audio service and media player service according to the control instructions of the application layer to control music playback, pause, volume adjustment and other functions.

[0144] The driver layer is located at the hardware level of the TV 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 and receiving Bluetooth music signals from other devices.

[0145] If Bluetooth devices are distinguished according to the reception and transmission of audio data, they can be divided into audio source devices and audio receiving devices, wherein the audio source device is a Bluetooth device for providing (sending) audio data to the audio receiving device, and the audio receiving device is a Bluetooth device for receiving the audio data sent by the audio source device. Thus, the audio receiving device can be used as an audio playback device for playing the audio data provided by the audio source device.

[0146] In some examples, the same Bluetooth device can switch Bluetooth modes according to different usage requirements. Bluetooth modes include audio source mode and audio sink mode. Sink mode and source mode are two Bluetooth modes specified in the Bluetooth audio transmission protocol (Advanced Audio Distribution Profile, A2DP). If the Bluetooth device is in source mode, the Bluetooth device currently acts as an audio source device, that is, the sender of audio data. If the Bluetooth device is in sink mode, the Bluetooth device currently acts as an audio receiving device, that is, the receiver of audio data.

[0147] In some embodiments, the display device 200 may be configured to use the source mode by default, that is, as an audio source device. In some examples, the display device 200 may switch between the source mode and the sink mode according to different usage scenarios.

[0148] In some embodiments, the display device 200 may be configured with a system Bluetooth function. A first Bluetooth switch for controlling the opening and closing of the system Bluetooth function may be configured in a system setting menu, a quick setting panel, a status bar, a shortcut menu, and the like.

[0149] Take the first Bluetooth switch configured in the system settings menu as an example, you can refer to Fig.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.

[0150] 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.

[0151] In some embodiments, when the Bluetooth function of the system is turned on and off by controlling 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.

[0152] 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.

[0153] In some embodiments, a monitoring module of a system control may be configured at the application layer, and the monitoring module may monitor the state changes of each system control. 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 is 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 is turned off by calling the system Bluetooth service. In this way, it is possible to control the turning on and off of the system Bluetooth function through the first Bluetooth switch.

[0154] 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 receipt of pairing requests from other Bluetooth devices due to 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.

[0155] 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. Fig.11 The system setting menu shown in the figure may include a second Bluetooth switch 1102. When the second Bluetooth switch is in the on state, the device visibility function is turned on, that is, if the system Bluetooth function is turned on, the display device 200 can be discovered by other Bluetooth devices. When the second Bluetooth switch is in the off state, the device visibility function is turned off, that is, if the system Bluetooth function is turned on, the display device 200 will not be discovered by other Bluetooth devices.

[0156] 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 of the display device 200 in scenarios other than using the application Bluetooth music function. The default state of the second Bluetooth switch can be an on state or an off state. 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 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 second Bluetooth switch can be set to an on state.

[0157] In some embodiments, the monitoring module of the system control can monitor the state change of the second Bluetooth switch, and control the opening and closing of the visibility function by calling the device visibility service, so as to realize the control of opening and closing the visibility function through the second Bluetooth switch. This process can refer to the process of controlling the opening and closing of the system Bluetooth function through the first Bluetooth switch, which is not repeated here.

[0158] 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 in an on state, the device shielding function is turned on, so that when the system Bluetooth function is turned on, a connection with a specified Bluetooth device will not be established. When the third Bluetooth switch is in an off state, the device shielding function is turned off, so that when the system Bluetooth function is turned on, a connection with a specified Bluetooth device can be established. The specified Bluetooth device may be a Bluetooth device specified by the user, or may be a Bluetooth device other than a Bluetooth device specified by the user to be connected, or may be a Bluetooth device other than a currently connected Bluetooth device.

[0159] 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 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 from 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.

[0160] In some embodiments, the Bluetooth devices that can establish a connection with the display device 200 can be managed through a white list of Bluetooth devices, and the Bluetooth devices not on the white list 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 white list can be dynamically adjusted according to the user's settings.

[0161] 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 the user's settings.

[0162] 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 according to the whitelist or blacklist. When 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. When the Bluetooth device is not a designated Bluetooth device, the device shielding service is not called to respond normally to the request of the Bluetooth device.

[0163] 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.

[0164] In the art mode, in order to expand the audio resources that the display device 200 can play, more abundant audio data can be provided through other Bluetooth devices. At this time, the display device 200 needs to be used as an audio receiving device to receive the audio data provided by other Bluetooth devices. That is, the display device 200 needs to be switched to sink mode. Correspondingly, 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.

[0165] In some embodiments, in the art mode, the display device 200 may Fig.12 The process shown plays audio from a Bluetooth device. The specific steps are as follows:

[0166] S1201: In the art mode, in response to the user's operation of turning on the application Bluetooth music function, the mode is switched to the audio receiving mode, and an operation guide page is displayed. When the default state of the first Bluetooth switch is the off state, the first Bluetooth switch is turned on.

[0167] In some embodiments, the art mode application can configure the switch of the application Bluetooth music function in the application settings menu. Fig. 9 The application setting menu 901 shown includes a switch for applying a Bluetooth music function, such as BT Music. Accordingly, the user can turn on the application Bluetooth music function by: when the display device 200 displays the display page, inputting a menu command through the menu key of the control device 100, controlling the display device 200 to open the application setting menu, and turning on the application Bluetooth music function by selecting the switch for the application Bluetooth music function in the application setting menu.

[0168] In some other embodiments, the art mode application can configure the switch of the application Bluetooth music function in the art mode setting page. Fig.10The art mode setting page shown includes a switch for applying a Bluetooth music function, such as BT Music. Accordingly, the user can turn on the application of the Bluetooth music function by: when the display device 200 displays the display page, inputting a menu command through the menu key of the control device 100, controlling the display device 200 to open the application setting menu, and opening the art mode setting page by selecting the setting item of the art mode setting in the application setting menu. The application of the Bluetooth music function is turned on by selecting the switch for the application of the Bluetooth music function in the art mode setting page.

[0169] Since the application of the 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 of the Bluetooth music function, the display device 200 is switched from the source mode to the sink mode to pair with other Bluetooth devices as an audio receiving device.

[0170] 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 in a turned off state, 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.

[0171] In some embodiments, in order 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 default state of the system Bluetooth function is restored. If the default state of the system Bluetooth function is on, the system Bluetooth function is kept on, that is, the first Bluetooth switch is kept on. If the default state of the system Bluetooth function is off, the system Bluetooth function is turned off again, that is, the first Bluetooth switch is switched back to the off state.

[0172] When the display device 200 uses the application Bluetooth music function, the implementation process of turning on the first Bluetooth switch to turn on the system Bluetooth function can refer to the following embodiment:

[0173] 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.

[0174] You can refer to Figure 4In 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, and 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 the registration monitoring module of the application can send a first notification to the Bluetooth switch module after it detects that the connection with the Bluetooth device is disconnected, or the activity manager can send a first notification to the Bluetooth switch module when it detects exiting the first application. 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.

[0175] In other embodiments, the display device 200 may monitor the usage status of the first application through a registered monitoring module of the system, and call the first Bluetooth switch to achieve a linkage effect between the application Bluetooth music function and the system Bluetooth function.

[0176] You can refer to Figure 4In the operating system shown, in the application layer, the relevant modules of the first application may also include a configuration file, which includes the configuration information of the first application. For example, the first application is an application that needs to use the system Bluetooth function, that is, after starting the first application, the system Bluetooth function needs to be turned on. In the application layer, a registration monitoring module of the system is also configured. During the startup process of the display device 200, the registration monitoring module of the system scans the configuration files of each application, wherein when the configuration file of the first application is scanned, the configuration information of the first application can be read, and the first application is registered to the application list according to the configuration information, and the applications included in the application list are all applications that need to use the system Bluetooth function, that is, after starting these applications, the system Bluetooth function needs to be turned on. The registration monitoring module of the system can monitor the startup of each activity and determine the application to be started according to the package name corresponding to the activity. After monitoring the activity of the first application, the registration monitoring module of the system can determine to start the first application. The registration monitoring module of the system determines whether the first application belongs to the application list, and after determining that the first application belongs to the application list, calls the system Bluetooth service to turn on the first Bluetooth switch and turn on the system Bluetooth service. In some embodiments, the configuration information of the first application may include a page with an application setting menu, so that when the system registration monitoring module registers the first application to the application list, it can accurately register to the page with the application setting menu, that is, when entering the first application and opening the application setting menu, the system Bluetooth service is turned on. After monitoring the activity of the page with the application setting menu, the system registration monitoring module can call the system Bluetooth service to turn on the first Bluetooth switch and turn on the system Bluetooth service.

[0177] When the activity manager detects closing the operation guide page or closing the pairing page, 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 is not paired with the Bluetooth device or a connection is established, the system's registration monitoring module can shut down the system's 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 exiting the first application, 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's Bluetooth service to turn off the first Bluetooth switch and the system's Bluetooth function.

[0178] 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 forcibly turned 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. Fig.11 A second Bluetooth switch 1102 is shown.

[0179] Accordingly, in order 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 default state of the device visibility function is restored. If the default state of the device visibility function is on, the device visibility function is kept on, that is, 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, that is, the second Bluetooth switch is switched to the off state.

[0180] 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.

[0181] 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 third Bluetooth switch is forced 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 interference from these Bluetooth devices.

[0182] Accordingly, in order 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 default state of the device shielding function is restored. If the default state of the device shielding function is on, the device shielding function is kept on, that is, 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, that is, the third Bluetooth switch is switched to the off state.

[0183] When the display device 200 uses the Bluetooth music function, the third Bluetooth switch is turned on to turn on the device shielding function. The process of turning on the first Bluetooth switch can refer to the process of turning on the first Bluetooth switch, which is not repeated here. The configuration information of the first application can include a whitelist or blacklist of Bluetooth devices.

[0184] In some embodiments, the states of the various Bluetooth switches of the display device 200 when using the Bluetooth music function are designed to be independent of the default state.

[0185] After the display device 200 is switched to the sink mode and the system Bluetooth function is turned on, it can be paired with other Bluetooth devices.

[0186] 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 category (Class of Device), the service's universally unique identifier (UUID), the device name, etc.

[0187] The device category is the current Bluetooth device type of the display device 200. For example, if it is currently in sink mode, the device type is an audio receiving device.

[0188] 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 the audio streaming function, the supported services include the Advanced Audio Distribution Profile (A2DP) service. Based on different Bluetooth modes, the supported A2DP services are also different. In sink mode, the Bluetooth device supports the A2DP receiving service. In source mode, the Bluetooth device supports the 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 the A2DP receiving service. Therefore, the display device 200 will register the UUID of the A2DP receiving service, for example, 0000110b-0000-1000-8000-00805f9b34fb.

[0189] 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 and represents the display device 200 .

[0190] In some embodiments, the display device 200 may display an operation guide page, which includes first guide information for performing a Bluetooth connection operation with the display device 200. The first guide 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.

[0191] You can refer to Fig.13The operation guide page shown may include first guide information. If the device name of the display device 200 is "Master Bedroom TV", the first guide information may be "Turn on the Bluetooth switch, select the Master Bedroom TV to pair and connect".

[0192] 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 by Bluetooth. Fig.13 The operation guide page shown in the figure shows the current status of the system Bluetooth function in the upper right corner, such as whether the Bluetooth function is available, and may also include an icon of the Bluetooth function.

[0193] For example, a user wants to use the first Bluetooth device to provide audio data for the display device 200. The first Bluetooth device can be a smart phone, a tablet computer, a computer, a 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.

[0194] In some embodiments, after the Bluetooth function is turned on, the first Bluetooth device is in source mode and can scan surrounding Bluetooth devices.

[0195] 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, the UUID of the service, the device name, etc.

[0196] The device type of the first Bluetooth device is an audio source device. In source mode, the display device 200 supports the A2DP sending service and registers the UUID of the A2DP sending 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.

[0197] When the display device 200 sends a pairing broadcast, the first Bluetooth device can scan the display device 200 .

[0198] After scanning the display device 200, the first Bluetooth device may display a search result list. The first Bluetooth device may 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 Fig.14 The search result list shown includes a result item for "master bedroom television".

[0199] The user determines that the device to be connected is the master bedroom TV according to the first guide information on the operation guide page, and then finds the result item of the master bedroom TV from the search result list, and selects the result item to pair 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, and the pairing request is used to request to establish a Bluetooth connection.

[0200] S1202: Display a pairing page according to the pairing request of the first Bluetooth device.

[0201] When the display device 200 is paired with the first Bluetooth device for the first time, a pairing page will be displayed, and the pairing page 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.

[0202] You can refer to Fig.15 The pairing page shown may include prompt information for prompting the user the device name of the first Bluetooth device currently requested to pair, such as my phone. In some embodiments, during the process of pairing 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 pairing button and a cancel button. If the user agrees to pair with the first Bluetooth device, the pairing button may be selected. If the user disagrees with pairing with the first Bluetooth device, the cancel button may be selected.

[0203] S1203, in response to the user's instruction to agree to pairing, pairing with the first Bluetooth device, and displaying a prompt page after pairing with the first Bluetooth device is successful.

[0204] If the user selects the pairing button to input an instruction to agree to pairing, the display device 200 is paired with the first Bluetooth device and a connection is established.

[0205] In some embodiments, after the first Bluetooth device is successfully paired with the display device 200, the service discovery protocol (SDP) can be used 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 registers the UUID of the A2DP receiving service. After recognizing that the display device 200 has registered the UUID of the A2DP receiving service, it can be confirmed that the display device 200 is in sink mode.

[0206] In some embodiments, after the display device 200 successfully pairs with the first Bluetooth device, it 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.

[0207] In some embodiments, in the art mode, if the user turns on the application Bluetooth music function again, the display device 200 can display the operation guide page. The process can refer to step S1201, which is not repeated here. The display device 200 can also display a list of paired devices. In some embodiments, the display device 200 can display a list of paired devices in the operation guide page. In other embodiments, the display device 200 can be configured to automatically exit the operation guide page after the second duration and display a list of paired devices.

[0208] 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 the 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 the items of these Bluetooth devices. Fig.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 item of myphone. If the display device 200 has established a Bluetooth connection with another Bluetooth device based on the application of 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 item of living room TV.

[0209] 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 input a connection instruction by selecting the item of the first Bluetooth device, and the display device 200 searches for the first Bluetooth device in response to the connection instruction, and establishes a connection with the first Bluetooth device after searching for the first Bluetooth device.

[0210] In some embodiments, after the first Bluetooth device is successfully paired with the display device 200 , the first Bluetooth device saves the pairing information of the display device 200 to quickly establish a connection with the display device 200 next time.

[0211] 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. Fig.17In the paired device list shown, if the device name of the display device 200 is the master bedroom TV, the paired device list may include the master bedroom TV item. If the first Bluetooth device has also established a connection with other Bluetooth devices, such as the device name of the other Bluetooth device is a Bluetooth headset, the paired device list may also include the Bluetooth headset item.

[0212] If the user wants to connect to the display device 200 , the user can select the item of the master bedroom TV and input a connection instruction. The first Bluetooth device responds to the connection instruction, searches for the display device 200 , and establishes a connection with the display device 200 after searching for the display device 200 .

[0213] 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.

[0214] 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 through the prompt page. 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. Fig.18 The prompt page shown may include a second guiding message, such as “Please open the mobile app and play your favorite songs.”.

[0215] 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, the first duration is 10 seconds, and the display device 200 automatically exits the prompt page after the prompt page is displayed for 10 seconds.

[0216] In some embodiments, the display device 200 may be configured to: in response to a user's return instruction, exit the prompt page and display the display page of the art mode application. For example, the user may input a return instruction by using the back key of the control device 100, and the display device 200 exits the prompt page in response to the return instruction.

[0217] In some embodiments, the display device 200 may display a prompt message in the prompt page, and the prompt message 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 back key, such as Fig.18 shown.

[0218] S1204: After receiving the first audio sent by the first Bluetooth device, play the first audio.

[0219] In some embodiments, if the user uses the first Bluetooth device to play the 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 playing state according to the play notification, and after determining that the first Bluetooth device is in the audio playing state, exit the prompt page and display the display page of the art mode application.

[0220] In some embodiments, the Bluetooth A2dp API of Android can be used to monitor the connection status and audio playback status of the first Bluetooth device. The connection status includes connected and unconnected, and the audio playback status includes playing and not playing.

[0221] 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.

[0222] In some embodiments, when the display device 200 determines that the first Bluetooth device is in an audio playback state, the device playback information may be displayed on the display page. The device playback information may 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. Fig.18 As shown in the display page, 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.

[0223] In some embodiments, the display device 200 hides the device playback information after a preset time, so as to avoid affecting the display effect of the artwork.

[0224] 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.

[0225] In some embodiments, when the display device 200 recognizes that the first Bluetooth device is in an audio playback state, it can control the first player to be in a muted state, and the first player is used to play the second audio. In this way, the volume of the second audio is 0, which is a muted effect and does not affect the playback quality of the first audio.

[0226] In some embodiments, when the display device 200 recognizes that the first Bluetooth device is in an audio playback state, it can control to pause or close the audio channel playing the second audio, so as to pause or exit playing 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.

[0227] In some embodiments, the display device 200 can establish connections with the first Bluetooth device and the second Bluetooth device at the same time, and the number of the second Bluetooth device is at least one.

[0228] 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.

[0229] 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's operation of opening the application's Bluetooth music function, and establish a connection with the second Bluetooth device in response to the user's instruction to select an item of the second Bluetooth device from the list.

[0230] In some embodiments, when the display device 200 is connected to multiple Bluetooth devices at the same time, one Bluetooth device may be selected to provide audio. Fig.19 The process shown switches the Bluetooth device. The specific steps are as follows:

[0231] S1901, in response to a user's control instruction, display a list of connected devices.

The user can input a control instruction by selecting the list button, and the display device 200 displays a list of connected devices in response to the control instruction.

[0233] 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.

[0234] You can refer to Fig. 20 In the display page shown, the display device 200 displays a connected device list 2002 in response to the user selecting the 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, the connected device list 2002 may include items of my phone and living room TV.

[0235] S1902, in response to an instruction from a user to select an item of a second Bluetooth device, stop receiving the first audio from the first Bluetooth device, and start receiving the audio sent by the second Bluetooth device.

[0236] The display device 200 currently plays 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 connected device list. 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.

[0237] S1903: After receiving the third audio sent by the second Bluetooth device, play the third audio.

[0238] When the display device 200 switches the audio source device to the second Bluetooth device, the second Bluetooth device can be in an audio playing state, an audio pause playing state, or an audio stop playing 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.

[0239] 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. And after a preset time, 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, which is not repeated here.

[0240] In some embodiments, the display device 200 may be configured to unmute the second audio when it detects that the currently used Bluetooth device pauses playing the audio, or detects that the currently used Bluetooth device is disconnected. Disconnecting from the currently used Bluetooth device may include: the currently used Bluetooth device is disconnected from the display device 200, or the display device 200 exits the art mode application, etc.

[0241] In some embodiments, the display device 200 mutes the second audio by setting the volume to 0; and unmutes the second audio by setting the volume to 1. When the volume is set to 1, the audio playback can be resumed.

[0242] In some embodiments, the display device 200 may be configured to switch back to the audio sending mode, ie, source mode, to serve as an audio source device when it detects that all connected Bluetooth devices are disconnected or after exiting the art mode application.

[0243] In some embodiments, when the display device 200 detects that the connection with the currently used Bluetooth device is disconnected, it displays a disconnection prompt message. 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. Fig.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.

[0244] In some embodiments, if the display device 200 is in source mode and is connected to a third Bluetooth device, which 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.

[0245] Referring to the aforementioned embodiments, in some examples, depending on the display device manufacturer, model, etc., the display device may be configured with a system Bluetooth switch (i.e., a first Bluetooth switch) and a visibility switch (i.e., a second Bluetooth switch), or may not be configured with a visibility switch, but only with a system Bluetooth switch. The following describes the music playing method provided in the embodiments of the present application in combination with different configurations of the display device.

[0246] like Fig.22A As shown, when the display device is only configured with the first Bluetooth switch, the music playing method provided in the embodiment of the present application includes the following steps:

[0247] S2201. In response to receiving a start instruction for a first application, start the first application.

[0248] The first application is at least used for playing pictures. For example, the first application may be an application for playing pictures, or an application for playing pictures and music. The embodiment of the present application does not limit the type of the first application.

[0249] Exemplarily, the start instruction may be a voice instruction or an operation instruction. When the start instruction is an operation instruction, the operation instruction may be an operation of selecting the first application icon, an operation input on a control device (such as a remote controller), or other pre-set operations for starting the first application. The embodiments of the present application do not limit the start method of the first application. For example, taking the start instruction as an operation of the user selecting the first application icon as an example, the display device starts the first application in response to receiving the operation of the user selecting the icon of the first application.

[0250] After the first application is started, the homepage may be displayed on the display page of the first application, or any picture preset or selected by the user may be displayed.

[0251] S2202: When displaying the first picture on the display page of the first application, in response to receiving a first control instruction for the first application, displaying a first menu corresponding to the first application on the display page, and maintaining display of the first picture on the display page.

[0252] The first menu is displayed on an upper layer of the first picture, and the first menu includes a first option for starting a Bluetooth function of the first application.

[0253] Exemplarily, the first picture may be a homepage picture of the first application, may be a picture preset by the user, or may be a picture selected by the user after starting the first application.

[0254] In some examples, when the first picture is displayed on the display page of the first application, in response to a first control instruction input by the user through the control device 100, a first menu corresponding to the first application is displayed on the display page of the first application. The first control instruction may be the user pressing a menu key of the control device 100 (such as a remote controller), or the user pressing a setting key of the control device 100.

[0255] For example, when the first control instruction is that the user presses the menu key of the control device 100, in response to the first control instruction, a first menu is displayed on the display page of the first application, and the first menu is the menu of the first application. Fig. 9 As shown, the first menu is displayed on the upper layer of the first picture. The first menu may also be called an application setting menu 901. The application setting menu 901 is displayed on the upper layer of the first picture. By displaying the application setting menu 901 on the upper layer of the first picture, the user can browse the first picture displayed in the display page of the first application while using the application setting menu 901.

[0256] Exemplarily, the first menu includes a first option for starting the Bluetooth function of the first application. Fig. 9As shown, the first option may be a BT Music option, and the BT Music option is used to activate the Bluetooth function of the first application.

[0257] In other examples, in response to a first control instruction input by the user through the control device 100, a first option, such as a BT Music option, may be directly displayed on the display page of the first application.

[0258] For another example, when the first control instruction is that the user presses the setting key of the control device 100, in response to the first control instruction, a first menu is displayed on the display page of the first application, and the first menu is a system setting menu, which is displayed on the upper layer of the first picture. By displaying the system setting menu on the upper layer of the first picture, the user can browse the first picture displayed on the display page of the first application while using the system setting menu. The system setting menu includes a Bluetooth option for starting the Bluetooth function of the first application.

[0259] S2203. In response to receiving a selection instruction for the first option, without exiting the first application, obtaining a state of a first Bluetooth switch, and if the first Bluetooth switch is in an off state, turning on the first Bluetooth switch to establish a Bluetooth connection with a first Bluetooth device.

[0260] The first Bluetooth switch is used to turn on or off the system Bluetooth function, and the first Bluetooth switch may also be referred to as the system Bluetooth switch.

[0261] For example, when the display device is only configured with a system Bluetooth switch and not a visibility switch, when the user selects the first option, the display device, in response to the selection instruction, can obtain the state of the system Bluetooth switch without exiting the first application, and when the system Bluetooth switch is in the off state, turn on the system Bluetooth switch to establish a connection with the first Bluetooth device. That is, when the application turns on the Bluetooth function in the first application, the Bluetooth function can be started without exiting the first application, and the first application is never exited during the process of turning on the system Bluetooth.

[0262] In some embodiments, the display device does not exit the first application and may include three situations. The first situation is to maintain the first application running in the foreground, the second situation is to maintain the first application visible, and the third situation is to maintain the operation guidance page, which includes the first guidance information, and the first guidance information is used to guide the user to use the Bluetooth device to pair with the display device.

[0263] The following are three situations in which the display device does not exit the first application. Fig. 22B The implementation method of step S2203 is described in detail. Fig. 22BAs shown, step S2203 may include the following steps S2203a, S2203b and S2203c. It should be noted that, according to the three situations in which the display device does not exit the first application, step S2203 may be implemented by any of the following steps S2203a, S2203b and S2203c.

[0264] S2203a. In response to receiving a selection instruction for the first option, maintaining the first application running in the foreground, and obtaining the state of the first Bluetooth switch. If the first Bluetooth switch is in an off state, turning on the first Bluetooth switch to establish a Bluetooth connection with the first Bluetooth device.

[0265] Exemplarily, after the user selects the first option to turn on the Bluetooth function of the first application, the display device will maintain the first application running in the foreground while obtaining the state of the first Bluetooth switch. If the first Bluetooth switch is found to be in the off state, the first Bluetooth switch will be turned on. It should be noted that during the process of the display device obtaining the state of the first Bluetooth switch and turning on the first Bluetooth switch, the first application is always running in the foreground. Therefore, the present application can turn on the Bluetooth function in the first application and turn on the system Bluetooth switch without exiting the first application, so that the display device can establish a connection with the Bluetooth device.

[0266] In some examples, the first application running in the foreground means that the first application is being operated or interacted with by the user, and the display interface of the first application is displayed on the display of the display device. When the first application is running in the foreground, the Activity of the first application is the Activity running in the foreground, and the Activity of the first application is at the top of the task stack. That is, the Activity of the first application is the Activity at the top of the application stack.

[0267] In some embodiments, Fig.23As shown, step S2203a may include: in response to receiving a selection instruction for the first option, maintaining the first application running in the foreground, and controlling the first application to send an acquisition instruction for acquiring the state of the first Bluetooth switch to the Bluetooth switch setting module; in response to the acquisition instruction, controlling the Bluetooth switch setting module to send a feedback instruction indicating the state of the first Bluetooth switch to the first application, and controlling the Bluetooth switch setting module to record the current state of the first Bluetooth switch; in response to the feedback instruction indicating that the first Bluetooth switch is in a closed state, controlling the first application to send a Bluetooth turn-on instruction to the Bluetooth switch setting module; in response to the Bluetooth turn-on instruction, controlling the Bluetooth switch setting module to turn on the first Bluetooth switch; controlling the first application to send a register Bluetooth status broadcast instruction and a receive mode switch instruction to the Bluetooth module; in response to the register Bluetooth status broadcast instruction and the receive mode switch instruction, the Bluetooth module controls the Bluetooth driver to turn on the receive mode switch, and broadcasts the device information of the display device to enable the Bluetooth module to enter sink mode.

[0268] In some examples, the Bluetooth module may enter the sink mode in three cases: the Bluetooth module may enter the sink mode after the Bluetooth switch setting module turns on the first Bluetooth switch; the Bluetooth module may enter the sink mode after the display device establishes a connection with the first Bluetooth device; and the Bluetooth module may enter the sink mode after the first Bluetooth device plays the first audio data. The embodiments of the present application do not limit the specific timing of the Bluetooth module entering the sink mode.

[0269] Exemplarily, when the display device establishes a Bluetooth connection with the first Bluetooth device, in response to receiving a selection instruction for the first option, the first application is maintained running in the foreground and an operation guidance page is displayed; and while maintaining the display of the operation guidance page, the status of the first Bluetooth switch is obtained, and if the first Bluetooth switch is in the off state, the first Bluetooth switch is turned on.

[0270] For example, the operation guidance page includes first guidance information for guiding the user to use a Bluetooth device to pair with a display device. The first guidance information may include the device name of the display device 200 to accurately prompt the Bluetooth device currently to be paired, so as to facilitate the user to quickly and accurately connect to the display device 200.

[0271] In some examples, when the display device 200 establishes a Bluetooth connection with the first Bluetooth device for the first time or when the display device 200 does not establish a Bluetooth connection with the first Bluetooth device for the first time, the operation guidance page can be displayed. Alternatively, when the display device 200 establishes a Bluetooth connection with the first Bluetooth device for the first time, the operation guidance page is displayed, and when the display device 200 does not establish a Bluetooth connection with the first Bluetooth device for the first time, the operation guidance page is not displayed.

[0272] Exemplarily, in response to receiving a selection instruction for the first option, the display device may display the operation guidance page while displaying the first picture while maintaining the first application running in the foreground.

[0273] For example, Fig.24 As shown, while maintaining the first application always running in the foreground, when the operation guidance page is displayed, the operation guidance page is displayed in a partial display area of ​​the display, and the first picture is displayed in another display area. Alternatively, the operation guidance page can be displayed on the upper layer of the first picture.

[0274] The music playing method provided in the embodiment of the present application can turn on the system Bluetooth switch and establish a connection with the first Bluetooth device while maintaining the first application running in the foreground when the first application displays the picture; and the first application is always running in the foreground during the process of establishing a connection between the display device and the first Bluetooth device, so that after the display device and the first Bluetooth device establish a Bluetooth connection, the first audio data selected by the user on the first Bluetooth device can be played while displaying the first picture on the display page of the first application. In other words, when the first application displays the picture, the present application can turn on the Bluetooth function without exiting the first application, ensuring that the system Bluetooth switch can be turned on without interrupting the user's appreciation of the art painting, and without the user's frequent operations, thereby improving the efficiency of turning on the system Bluetooth.

[0275] S2203b. In response to receiving a selection instruction for the first option, maintaining the first application visible, and obtaining the state of the first Bluetooth switch. If the first Bluetooth switch is in an off state, turning on the first Bluetooth switch to establish a Bluetooth connection with the first Bluetooth device.

[0276] For example, after the user selects the first option to turn on the Bluetooth function of the first application, the display device obtains the state of the first Bluetooth switch while maintaining the visibility of the first application. If the first Bluetooth switch is found to be in the off state, the first Bluetooth switch is turned on. It should be noted that the first application is always visible during the process of the display device obtaining the state of the first Bluetooth switch and turning on the first Bluetooth switch. Therefore, the present application can turn on the Bluetooth function in the first application and turn on the system Bluetooth switch without exiting the first application, so that the display device can establish a connection with the Bluetooth device.

[0277] In some examples, the first application is visible means that when the first application is turned on, the first application can continue to be displayed on the display while the user is performing other operations, that is, the user can see the application interface of the first application on the display. For example, part of the display area of ​​the display displays the application interface of the first application (such as the first picture), and the entire display area of ​​the display displays the application interface of the first application (such as the first picture). When the first application is visible to the user, the application interface of the first application can be displayed at the top layer, or it can be suspended on the upper layer of other controls. For example, the menu or boot page or other pages of the application can be displayed simultaneously with the application interface of the first application, and the menu or boot page or other pages of the application can also be displayed on the upper layer of the application interface of the first application, and the application interface of the first application is visible to the user.

[0278] In some embodiments, Fig.23 As shown, step S2203b may include: in response to receiving a selection instruction for the first option, maintaining the first application visible, and controlling the first application to send an acquisition instruction for acquiring the state of the first Bluetooth switch to the Bluetooth switch setting module; in response to the acquisition instruction, controlling the Bluetooth switch setting module to send a feedback instruction indicating the state of the first Bluetooth switch to the first application, and controlling the Bluetooth switch setting module to record the current state of the first Bluetooth switch; in response to the feedback instruction indicating that the first Bluetooth switch is in a closed state, controlling the first application to send a Bluetooth turn-on instruction to the Bluetooth switch setting module; in response to the Bluetooth turn-on instruction, controlling the Bluetooth switch setting module to send a command to turn on the first Bluetooth switch; controlling the first application to send a register Bluetooth status broadcast instruction and a receive mode switch instruction to the Bluetooth module; in response to the register Bluetooth status broadcast instruction and the receive mode switch instruction, the Bluetooth module controls the Bluetooth driver to turn on the receive mode switch, and broadcasts the device information of the display device to enable the Bluetooth module to enter sink mode.

[0279] The music playing method provided in the embodiment of the present application can turn on the system Bluetooth switch and establish a connection with the first Bluetooth device while maintaining the visibility of the first application when the first application displays the picture; and the first application is always visible during the process of establishing a connection between the display device and the first Bluetooth device, so that after the display device and the first Bluetooth device establish a Bluetooth connection, the first audio data selected by the user on the first Bluetooth device can be played while displaying the first picture on the display page of the first application. In other words, when the first application displays the picture, the present application can turn on the Bluetooth function without exiting the first application, ensuring that the system Bluetooth switch can be turned on without interrupting the user's appreciation of the art painting, and without the user's frequent operations, thereby improving the efficiency of turning on the system Bluetooth.

[0280] S2203c. In response to receiving a selection instruction for the first option, an operation guide page is displayed; and a first Bluetooth switch is configured on the display device. While maintaining the operation guide page, the state of the first Bluetooth switch is obtained. If the first Bluetooth switch is in an off state, the first Bluetooth switch is turned on to establish a Bluetooth connection with the first Bluetooth device.

[0281] Exemplarily, after the user selects the first option to turn on the Bluetooth function of the first application, the display device obtains the state of the first Bluetooth switch while maintaining the display of the operation guide page. If it is obtained that the first Bluetooth switch is in the off state, the first Bluetooth switch will be turned on.

[0282] In some examples, the operation guidance page refers to first guidance information for guiding the user to pair the Bluetooth device with the display device. Fig.13 As shown, the first guidance information included in the operation guidance page may be "turn on the Bluetooth switch, select the master bedroom TV for pairing and connection", wherein the device name of the display device 200 is "master bedroom TV".

[0283] In some embodiments, Fig.23 As shown, step S2203c includes: while maintaining the operation guide page, controlling the first application to send an acquisition instruction for acquiring the state of the first Bluetooth switch to the Bluetooth switch setting module; in response to the acquisition instruction, controlling the Bluetooth switch setting module to send a feedback instruction indicating the state of the first Bluetooth switch to the first application, and controlling the Bluetooth switch setting module to record the current state of the first Bluetooth switch; in response to the feedback instruction indicating that the first Bluetooth switch is in a closed state, controlling the first application to send a Bluetooth turn-on instruction to the Bluetooth switch setting module; in response to the Bluetooth turn-on instruction, controlling the Bluetooth switch setting module to send a turn-on instruction for the first Bluetooth switch; controlling the first application to send a register Bluetooth status broadcast instruction and a receive mode switch instruction to the Bluetooth module; in response to the register Bluetooth status broadcast instruction and the receive mode switch instruction, the Bluetooth module controls the Bluetooth driver to turn on the receive mode switch, and broadcasts the device information of the display device to enable the Bluetooth module to enter sink mode.

[0284] The music playing method provided in the embodiment of the present application can turn on the system Bluetooth switch and establish a connection with the first Bluetooth device while maintaining the operation guide page when the first application displays the picture; and maintain the operation guide page during the process of establishing a connection between the display device and the first Bluetooth device, so that after the display device and the first Bluetooth device establish a Bluetooth connection, the first audio data selected by the user on the first Bluetooth device can be played while displaying the first picture on the display page of the first application. In other words, when the first application displays the picture, the present application can turn on the Bluetooth function without exiting the first application, ensuring that the system Bluetooth switch can be turned on without interrupting the user's appreciation of the art painting, and without the user's frequent operations, thereby improving the efficiency of turning on the system Bluetooth.

[0285] In some embodiments, establishing a Bluetooth connection with the first Bluetooth device in the above step S2203 includes: when the display device establishes a connection with the first Bluetooth device for the first time, in response to receiving a pairing request from the first Bluetooth device, displaying a pairing page; in response to an instruction from the user agreeing to the pairing, establishing a Bluetooth connection with the first Bluetooth device and displaying a prompt page; wherein the prompt page is used to prompt the user to play audio data on the first Bluetooth device.

[0286] For example, Fig.23 As shown, the first Bluetooth device sends a Bluetooth connection request to the Bluetooth driver module of the display device 200, and the Bluetooth driver module sends the Bluetooth connection request to the Bluetooth module. After receiving the instruction to confirm and agree to pairing, the Bluetooth module establishes a Bluetooth connection with the first Bluetooth device; at the same time, the Bluetooth module sends a Bluetooth connection success broadcast to the first application.

[0287] In some examples, when the display device 200 and the first Bluetooth device are paired for the first time, a pairing page is displayed, and the pairing page includes inquiry information, which is used to ask the user whether to agree to pair with the first Bluetooth device, further ensuring the data security of the display device 200. The user can select the pairing button in the pairing page to enter an instruction to agree to pair. Fig.15 As shown, after the user inputs an instruction to agree to pairing on the pairing request page, the display device 200 is paired with the first Bluetooth device and a connection is established.

[0288] For example, after the display device 200 successfully pairs with the first Bluetooth device and establishes a connection, the display device 200 may save the pairing information of the first Bluetooth device.

[0289] Exemplarily, after the display device 200 establishes a connection with the first Bluetooth device, the display may display a prompt page, which is used to prompt the user to play audio data on the first Bluetooth device. Fig.18As shown, the prompt page can also be used to prompt the user that the connection is successful and the audio data can be played through the connected first Bluetooth device.

[0290] The music playing method provided in the embodiment of the present application can display a pairing page during the process of establishing a connection between the display device and the first Bluetooth device, so that the user can confirm whether to agree to pair with the first Bluetooth device, thereby ensuring the accuracy and security of the Bluetooth connection process. At the same time, after the display device and the first Bluetooth device are connected, a prompt page can also be displayed, which can remind the user to play audio data on the first Bluetooth device so that the user can play his favorite music in time.

[0291] In some embodiments, there are multiple ways to exit the prompt page, for example, after the prompt page displays a first preset time, the prompt page is exited, and the first picture is displayed on the display page. For another example, in response to a received return instruction, the prompt page is exited, and the first picture is displayed on the display page. For another example, after detecting that the first Bluetooth device is in an audio playback state, the prompt page is exited, and the first picture is displayed on the display page.

[0292] In some examples, after displaying the prompt page, the display can exit the prompt page according to a preset exit rule. The preset exit rule may include: starting the timer when the prompt page is displayed, and automatically exiting the prompt page when the timer reaches a first preset time; or, exiting the prompt page in response to an exit command input by a remote controller or an exit command input by voice; or, based on detecting the audio playback state of the first Bluetooth device, automatically exiting the prompt page when it is detected that the first Bluetooth device is in the audio playback state.

[0293] Exemplarily, after exiting the prompt page, the display may display the first picture on the display page. For example, when the user starts playing the first audio data through the first Bluetooth device, the first Bluetooth device may send a play notification to the display device 200 and send the first audio data. The display device 200 may determine that the first Bluetooth device is in the audio playing state according to the play notification, and after determining that the first Bluetooth device is in the audio playing state, exit the prompt page and display the first picture.

[0294] Through the above solution, after the display device and the first Bluetooth device are connected, the prompt page can exit the display according to the preset exit rule. Among them, the prompt page can automatically exit the display without the user's operation, or the prompt page can be exited according to the user's needs. After the prompt page exits, the display page continues to display the first picture, so that the user can continue to appreciate the art painting.

[0295] In some embodiments, establishing a Bluetooth connection with the first Bluetooth device in the above step S2203 also includes: when the display device is not establishing a connection with the first Bluetooth device for the first time, displaying a list of paired devices on the display page according to the stored pairing information, and maintaining the first picture displayed on the display page; in response to receiving a selection operation on the information of the first Bluetooth device in the list of paired devices, establishing a connection with the first Bluetooth device.

[0296] In some examples, the display device 200 can save the pairing information of the successfully paired Bluetooth devices according to the historical Bluetooth pairing situation to obtain a paired device list. That is, the paired device list includes information of multiple successfully paired Bluetooth devices. Among them, the information of multiple successfully paired Bluetooth devices includes information of the first Bluetooth device. For example, the information of each Bluetooth device in the paired device list may include a device name, a device serial number or other device identification, which is not limited in this application.

[0297] In some examples, the user can select the Bluetooth device that he wants to connect to this time based on the paired device list. When the user wants to connect to the first Bluetooth device, he can select the information of the first Bluetooth device in the paired device list to input a connection instruction, search for the first Bluetooth device, and establish a connection with the first Bluetooth device after searching for the first Bluetooth device. Fig.16 As shown, the paired device list displayed on the display page includes information of two Bluetooth devices (such as device names). When the user selects a Bluetooth device with the device name "my phone", the display device 200 can establish a connection with "my phone".

[0298] For example, when displaying the paired device list, the display can maintain the first image displayed on the display page. The paired device list can be displayed in a part of the display area of ​​the display page, and the first image can be displayed in another part of the display area of ​​the display page; or the first image can be displayed in the entire display area of ​​the display page, and the paired device list can be displayed on top of the first image, such as Fig.16 As shown, the paired device list is displayed on the upper layer of the first picture.

[0299] Through the above scheme, when the display device is not establishing a connection with the first Bluetooth device for the first time, a list of paired devices can be displayed on the display page, and the first picture can be kept displayed on the display page. The user can select the Bluetooth device to be connected through the list of paired devices to quickly establish a Bluetooth connection; at the same time, the user can also continue to appreciate the art paintings during the Bluetooth connection process, which can enhance the user experience.

[0300] S2204: While the first application displays the first picture, receive and play the first audio data sent by the first Bluetooth device.

[0301] For example, Fig.23 As shown, when the first picture is displayed on the display page of the display, if the Bluetooth connection between the display device and the first Bluetooth device is successful, then when the first Bluetooth device plays audio, the first Bluetooth device can transmit the audio data to the Bluetooth driver module of the display device 200 through the A2DP protocol. The Bluetooth driver module receives the audio data and sends a data transmission instruction to the Bluetooth module. The Bluetooth module plays the audio data according to the data transmission instruction and broadcasts the playback success to the first application.

[0302] In some examples, when displaying the first picture, the display device 200 may set background music for the first picture, that is, the background music corresponding to the first picture may be played while displaying the first picture. In this case, the sound of the background music may affect the first audio data played by the first Bluetooth device, thereby reducing the user experience.

[0303] In some embodiments, step S2204 includes: if the first picture is equipped with second audio data, when the first audio data sent by the first Bluetooth device is received, the second audio data is muted or paused, and the first audio data is played while displaying the first picture.

[0304] In some examples, the second audio data may be background audio data corresponding to the first image. While the first application displays the first image, the display device plays the second audio data. In order to prevent the second audio data from affecting the first audio data played by the first Bluetooth device, the second audio data may be muted or paused when the audio data sent by the first Bluetooth device is received.

[0305] Exemplarily, when the first audio data sent by the first Bluetooth device is received, the volume of the audio track of the display device 200 can be set to 0 to mute the second audio data. When the second audio data is muted, the volume of the second audio data is reduced to 0, but the second audio data continues to play. Pausing the second audio data is to control the second audio data to stop playing. When the second audio data is paused or the volume is reduced to 0, it will not affect the playback of the first audio data.

[0306] For example, continue to refer to Fig.23 After the Bluetooth module sends the audio data playback success information of the first Bluetooth device to the first application, the first application obtains the playback success information and determines whether there is local video audio (such as the second audio data) being played. If there is local video audio being played, the playback of the local video audio is paused. Alternatively, the volume of the local video audio playback can be adjusted to 0.

[0307] Based on the above scheme, when the first picture is accompanied by background audio (i.e., the second audio data), the display device can mute or pause the background audio of the first picture after receiving the first audio data sent by the first Blue Night device, thereby avoiding the background audio affecting the playback of the first audio data when the user is enjoying the first picture, affecting the user experience.

[0308] In some embodiments, after step S2204, the method further includes: in response to receiving an instruction from the first Bluetooth device to pause playing the first audio, unmuting the second audio data; or, in response to receiving an instruction from the first Bluetooth device to pause playing the first audio, continuing to play the second audio data.

[0309] Exemplarily, when the display device 200 plays the first audio data, the first Bluetooth device can perform playback control on the first audio data, such as pause playback control. When the display device 200 receives an instruction from the first Bluetooth device to pause playback of the first audio data, the display device 200 adjusts the volume of the audio track of the display device from 0 to the initial volume in response to the instruction to pause playback of the first audio data; or, cancels the pause playback of the second audio data to continue playing the second audio data. In this case, the second audio data associated with the first picture can be played while the first application displays the first picture while the first Bluetooth device pauses playback of the first audio data.

[0310] In some examples, such as Fig.23 As shown, when the first Bluetooth device pauses playing the first audio data, the first Bluetooth device can send the audio pause instruction to the Bluetooth driver module of the display device 200 through the Bluetooth protocol. The Bluetooth driver module receives the pause instruction and sends the pause status instruction to the Bluetooth module. The Bluetooth module pauses the playing of the audio data according to the instruction, and sends the play pause broadcast to the first application. The first application obtains the pause status sent by the Bluetooth module, determines whether there is local video audio playing, and if so, resumes the playing of the local video audio. For example, resuming the playing of the local video audio includes restoring the volume of the local video audio to the initial volume, or continuing to play the local video audio.

[0311] Based on the above solution, if the first Bluetooth device pauses playing the first audio data, the background audio can be muted or controlled to continue playing, so that the user can continue to play the audio while enjoying the first picture, thereby improving the user experience.

[0312] In some embodiments, after step S2204, the method further includes: if the display device also establishes a Bluetooth connection with a second Bluetooth device, then when playing the first audio data, in response to receiving a second control instruction input for a list option on the display page, displaying a list of connected devices on the display page, and maintaining display of the first picture on the display page; in response to receiving a selection instruction for a second Bluetooth device in the connected device list, terminating the reception of the first audio data sent by the first Bluetooth device, and starting the reception of the third audio data sent by the second Bluetooth device; and playing the third audio data sent by the second Bluetooth device while displaying the first picture in the first application.

[0313] In some examples, a list button may be configured on the display page, and the list button is an entry to the connected device list. For example, the user may select the list button (i.e., input the second control instruction) through the remote control, and the display device 200 opens the connected device list on the display page in response to the second control instruction. The connected device list includes information about at least two Bluetooth devices that have established a Bluetooth connection with the display device, such as the connected device list may include the device names of at least two Bluetooth devices.

[0314] For example, when the connected device list is displayed on the display page, the first image is still displayed on the display page. For example, the connected device list can be displayed on top of the first image, or the connected device list and the first image can be displayed in different display areas of the display page.

[0315] In some examples, the user can select a Bluetooth device, such as a second Bluetooth device, in the connected device list through the remote control to send a selection instruction of the second Bluetooth device to the display device 200. The display device 200 stops playing the first audio data sent by the first Bluetooth device and receives the third audio data sent by the second Bluetooth device according to the selection instruction of the second Bluetooth device. The display device 200 plays the third audio data sent by the second Bluetooth device while displaying the first picture in the first application.

[0316] In some examples, the display device 200 can establish Bluetooth connections with multiple Bluetooth devices at the same time. For example, the display device 200 can establish Bluetooth connections with a first Bluetooth device and a second Bluetooth device at the same time. In response to the selection instruction of the second Bluetooth device, the display device 200 switches the audio source device to the second Bluetooth device, while maintaining the connection with the first Bluetooth device, but no longer receiving the first audio data sent by the first Bluetooth device, and starts receiving the third audio data sent by the second Bluetooth device.

[0317] For example, the display device 200 may send a first notification to the first Bluetooth device to notify the first Bluetooth device to stop receiving the first audio data sent by it, and the first Bluetooth device pauses playing the first audio data according to the first notification. At the same time, the display device 200 may also send a second notification to the second Bluetooth device to notify the second Bluetooth device that it can receive the third audio data sent by it, and the second Bluetooth device plays the third audio data according to the second notification.

[0318] Based on the above scheme, when the display device plays the first audio data sent by the first Bluetooth device, the user can display the list of connected devices through the display page for the user to choose to switch the Bluetooth device, and after the display device is connected to the second Bluetooth device, the first audio data sent by the first Bluetooth device is stopped from playing, and the third audio data sent by the second Bluetooth device is played. At the same time, in the process of connecting to the second Bluetooth device, the first picture is maintained on the display page. Therefore, in the process of the user switching Bluetooth devices, the user can continue to enjoy the first picture, and the audio data can be switched to the audio data sent by the most recently connected Bluetooth device, thereby avoiding the problem of audio data interruption during the Bluetooth device switching process, and ensuring the continuity of audio playback.

[0319] In some embodiments, after step S2204, the method further includes: in response to receiving an instruction to disconnect the Bluetooth connection sent by the first Bluetooth device, unmuting the second audio data; if the display device establishes a Bluetooth connection with a third Bluetooth device, sending the second audio data to the third Bluetooth device, so that the second audio data is played through the third Bluetooth device while the first application displays the first picture; if the display device does not establish a Bluetooth connection with the third Bluetooth device, playing the second audio data while the first application displays the first picture.

[0320] In some examples, when the display device 200 receives the instruction to disconnect the Bluetooth connection sent by the first Bluetooth device, the display device 200 enters the source mode. Since the playback of the first audio data is disconnected, the second audio data can be muted and the second audio data can continue to be played. While playing the second audio data, the display device can detect whether there are other Bluetooth devices that have established a connection.

[0321] In some examples, if it is detected that the display device 200 establishes a Bluetooth connection with a third Bluetooth device after disconnecting the Bluetooth connection with the first Bluetooth device, the second audio data is played through the third Bluetooth device while the first application displays the first picture. If it is detected that the display device 200 does not establish a Bluetooth connection with other Bluetooth devices after disconnecting the Bluetooth connection with the first Bluetooth device, the display device 200 plays the second audio data while the first application displays the first picture, that is, the second audio data is played through the audio player of the display device. The third Bluetooth device can be a device such as a Bluetooth speaker working in Bluetooth receiving mode.

[0322] like Fig.23 As shown, after the first Bluetooth device disconnects the Bluetooth connection with the display device 200, the Bluetooth disconnection instruction can be transmitted to the Bluetooth driver module of the display device 200 through the Bluetooth protocol. The Bluetooth driver module receives the disconnection instruction and sends a transmission status instruction to the Bluetooth module to indicate that the first Bluetooth device is disconnected from the display device 200. The Bluetooth module releases the player and sends a disconnection broadcast to the first application. For example, after determining that the display device 200 is disconnected from the first Bluetooth device, the first application can send a Bluetooth switch status recovery instruction and a sink switch off instruction to the Bluetooth switch setting module to make the display device turn off the sink mode and enter the source mode.

[0323] Based on the above scheme, when the display device plays the first audio data sent by the first Bluetooth device, if the Bluetooth connection between the display device and the first Bluetooth device is disconnected, the background audio of the first picture (i.e., the second audio data) is unmuted. In this case, if the display device does not establish a Bluetooth connection with the Bluetooth speaker (i.e., the third Bluetooth device), the display device plays the second audio data while the first application displays the first picture; if a Bluetooth connection is established between the display device and the Bluetooth speaker, the second audio data is played through the Bluetooth speaker. Therefore, after the display device is disconnected from the first Bluetooth device, the present application can continue to play the background audio while displaying the first picture, and can also continue to play the background audio through the Bluetooth speaker, avoiding the problem of audio playback interruption due to Bluetooth connection disconnection.

[0324] In some embodiments, after step S2204, the method further includes: in response to receiving an exit instruction for the first application, restoring the first Bluetooth switch to a default state.

[0325] Exemplarily, the display device 200 receives the exit instruction of the first application and automatically restores the first Bluetooth switch to the default state. For example, taking the default state of the first Bluetooth switch as the off state as an example, if the first Bluetooth switch is off before the first application is started, and the first Bluetooth switch is turned on through the BT music option after the first application is started, then after exiting the first application, the state of the first Bluetooth switch is restored to the default off state.

[0326] In some examples, such as Fig.23 As shown, when the first application exits, in response to the instruction to exit the application, the first application can send a command to cancel the Bluetooth status registration and close the sink mode to the Bluetooth module of the display device 200. After obtaining the command to cancel the Bluetooth status registration and close the sink mode, the Bluetooth module can send a command to close the sink mode to the Bluetooth driver module. The Bluetooth driver module closes the sink mode and sends a disconnection to the first Bluetooth device. At the same time, the first application can also send a command to restore the Bluetooth switch state to the Bluetooth switch setting module in the display device 200, and the Bluetooth switch setting module restores the state of the first Bluetooth switch to the default state.

[0327] Based on the above scheme, when the first application is running in the foreground, the state of the first Bluetooth switch (i.e., the system Bluetooth switch) may have changed (such as switching from the off state to the on state). In order to avoid affecting the performance of the display device, the first Bluetooth switch can be restored to the default state after the first application exits.

[0328] In some embodiments, after step S2204, the method further includes: after detecting that the first Bluetooth device is in an audio playback state, displaying the device playback information of the first Bluetooth device on the display page of the first application, and maintaining the first picture displayed on the display page; after the device playback information of the first Bluetooth device is displayed for a second preset time length, hiding the device playback information of the first Bluetooth device.

[0329] Exemplarily, after the display device 200 recognizes that the first Bluetooth device is in an audio playback state, it can display device playback information on the display page, wherein the device playback information of the first Bluetooth device includes the device name and device icon of the first Bluetooth device, and the device icon is used to identify the device type of the second Bluetooth device.

[0330] In some examples, the device playback information of the first Bluetooth device can be displayed on the display page all the time, or can be displayed for a period of time. For example, a timer is started when the device playback information of the first Bluetooth device starts to be displayed, and when the timer reaches a second preset time, the device playback information of the first Bluetooth device is hidden.

[0331] Based on the above solution, after the first Bluetooth device is in the audio playback state, the display device displays the first picture on the display page and displays the device playback information on the display page, so that the user can understand the device information of the Bluetooth device currently playing the audio data. At the same time, in order to avoid the device playback information affecting the user's appreciation of the first picture, after the second preset time, the display device can automatically hide the device playback information, so that the user can continue to appreciate the art painting, thereby improving the user experience.

[0332] Combine the following Fig.25A When the display device is configured with a first Bluetooth switch (ie, a system Bluetooth switch) and a second Bluetooth switch (ie, a visibility switch), the music playing method provided in the embodiment of the present application is described. Fig.25A As shown, when the display device is configured with a first Bluetooth switch and a second Bluetooth switch, the music playing method provided in the embodiment of the present application includes the following steps:

[0333] S2501: In response to receiving a start instruction for a first application, start the first application.

[0334] S2502. When displaying a first picture on a display page of a first application, in response to receiving a first control instruction for the first application, displaying a first menu corresponding to the first application on the display page, and maintaining display of the first picture on the display page.

[0335] It should be noted that the execution process of step S2501 and step S2502 is similar to the above-mentioned step S2201 and step S2202. To avoid repetition, they are not repeated here.

[0336] S2503. In response to receiving a selection instruction for the first option, without exiting the first application, obtaining the status of the first Bluetooth switch and the second Bluetooth switch, and establishing a Bluetooth connection with the first Bluetooth device after turning on the first Bluetooth switch and / or the second Bluetooth switch.

[0337] Among them, the first Bluetooth switch is used to turn on or off the system Bluetooth function, and the second Bluetooth switch is used to turn on or off the device visibility function.

[0338] Exemplarily, when the display device is configured with a system Bluetooth switch and a visibility switch, when the user selects the first option, the display device, in response to the selection instruction, can obtain the state of the system Bluetooth switch and the state of the visibility switch without exiting the first application. If the first Bluetooth switch and the second Bluetooth switch are in the off state, a connection is established with the first Bluetooth device after the first Bluetooth switch and the second Bluetooth switch are turned on. If the first Bluetooth switch is in the on state and the second Bluetooth switch is in the off state, a connection is established with the first Bluetooth device after the second Bluetooth switch is turned on.

[0339] In some examples, when the first Bluetooth switch state is off, the display device cannot establish a Bluetooth connection with the Bluetooth device; when the first Bluetooth switch state is on and the second Bluetooth state is off, although the Bluetooth function of the display device is on, the display device cannot be discovered by other Bluetooth devices, and thus cannot establish a connection with the Bluetooth device. Therefore, only when both the first Bluetooth device and the second Bluetooth device are on, can the display device 200 be further connected to the first Bluetooth device.

[0340] Exemplarily, the first Bluetooth switch and the second Bluetooth switch are both in the on state, which includes two situations. The first situation is that the first Bluetooth switch and the second Bluetooth switch are both in the off state, and the second situation is that the first Bluetooth switch is in the on state and the second Bluetooth switch is in the off state.

[0341] The following describes the implementation of step S2503 in combination with two situations where both the first Bluetooth switch and the second Bluetooth switch are in the on state. Fig.25B As shown, step S2503 can be implemented by any of the following steps S2503a and S2503b.

[0342] S2503a, in response to receiving a selection instruction for the first option, obtaining the status of the first Bluetooth switch and the second Bluetooth switch without exiting the first application, and if the first Bluetooth switch and the second Bluetooth switch are in the off state, turning on the first Bluetooth switch and the second Bluetooth switch to establish a Bluetooth connection with the first Bluetooth device.

[0343] In some examples, the monitoring module can monitor the status of the first Bluetooth switch and the second Bluetooth switch. When the first Bluetooth switch and the second Bluetooth switch are both in the off state, the first Bluetooth switch and the second Bluetooth switch need to be turned on to enable the system Bluetooth function and the device visibility function. For example, the user can turn on the first Bluetooth switch and the second Bluetooth switch in the system setting menu through the remote control.

[0344] It should be noted that, in step S2503a, not exiting the first application still includes three situations, the first situation is to keep the first application running in the foreground, the second situation is to keep the first application visible, and the third situation is to keep the operation guide page. The relevant descriptions of the three ways of not exiting the application have been described in the above embodiments (such as S2203a, S2203b and S2203c), and will not be repeated here to avoid repetition.

[0345] Exemplarily, step S2503a includes: in response to receiving a selection instruction for the first option, while maintaining the first application running in the foreground, obtaining the status of the first Bluetooth switch and the second Bluetooth switch; if the first Bluetooth switch and the second Bluetooth switch are in the off state, turning on the first Bluetooth switch and the second Bluetooth switch to establish a Bluetooth connection with the first Bluetooth device.

[0346] Exemplarily, step S2503a includes: in response to receiving a selection instruction for the first option, while maintaining the first application visible, obtaining the status of the first Bluetooth switch and the second Bluetooth switch; if the first Bluetooth switch and the second Bluetooth switch are in the off state, turning on the first Bluetooth switch and the second Bluetooth switch to establish a Bluetooth connection with the first Bluetooth device.

[0347] Exemplarily, step S2503a includes: in response to receiving a selection instruction for the first option, while maintaining the operation guidance page, obtaining the status of the first Bluetooth switch and the second Bluetooth switch; if the first Bluetooth switch and the second Bluetooth switch are in the off state, turning on the first Bluetooth switch and the second Bluetooth switch to establish a Bluetooth connection with the first Bluetooth device.

[0348] In some embodiments, step S2503 includes: in response to receiving a selection instruction for the first option, while maintaining the first application from exiting (such as maintaining the first application running in the foreground, or maintaining the first application visible, or maintaining the operation guide page), controlling the first application to send an acquisition instruction for acquiring the status of the first Bluetooth switch and the second Bluetooth switch to the Bluetooth switch setting module; in response to the acquisition instruction, controlling the Bluetooth switch setting module to send a feedback instruction indicating the status of the first Bluetooth switch and the second Bluetooth switch to the first application, and controlling the Bluetooth switch setting module to record the current status of the first Bluetooth switch and the second Bluetooth switch; in response to the feedback instruction indicating that the first Bluetooth switch and the second Bluetooth switch are in the off state, controlling the first application to send a Bluetooth turn-on instruction to the Bluetooth switch setting module; in response to the Bluetooth turn-on instruction, controlling the Bluetooth switch setting module to turn on the first Bluetooth switch and the second Bluetooth switch; controlling the first application to send a register Bluetooth status broadcast instruction and a receive mode switch instruction to the Bluetooth module; in response to the register Bluetooth status broadcast instruction and the receive mode switch instruction, the Bluetooth module controls the Bluetooth driver to turn on the receive mode switch, and broadcasts the device information of the display device to enable the Bluetooth module to enter sink mode.

[0349] In the music playing method provided in the embodiment of the present application, the display device can turn on the first Bluetooth switch and the second Bluetooth switch to establish a Bluetooth connection between the display device and the first Bluetooth device while maintaining the first application running in the foreground, maintaining the first application visible, or maintaining the operation guide page. Moreover, during the process of establishing the connection between the display device and the first Bluetooth device, the first application is never exited, so that after the Bluetooth connection is established between the display device and the first Bluetooth device, the first audio data sent by the first Bluetooth device can be played while the first application displays the first picture, so that the user can select the corresponding audio according to his or her preferences while appreciating the art painting.

[0350] S2503b, in response to receiving a selection instruction for the first option, without exiting the first application, obtaining the status of the first Bluetooth switch and the second Bluetooth switch; if the first Bluetooth switch is in the on state and the second Bluetooth switch is in the off state, turning on the second Bluetooth switch to establish a Bluetooth connection with the first Bluetooth device.

[0351] In some examples, when the first Bluetooth switch is detected to be in the on state and the second Bluetooth switch is in the off state, only the second Bluetooth switch needs to be turned on to enable the device visibility function. For example, the user can turn on the second Bluetooth switch in the system settings menu using a remote control.

[0352] It should be noted that, in step S2503b, not exiting the first application still includes three situations, the first situation is to keep the first application running in the foreground, the second situation is to keep the first application visible, and the third situation is to keep the operation guide page. The relevant descriptions of the three ways of not exiting the application have been described in the above embodiments (such as S2203a, S2203b and S2203c), and will not be repeated here to avoid repetition.

[0353] Exemplarily, step S2503b includes: in response to receiving a selection instruction for the first option, while maintaining the first application running in the foreground, obtaining the status of the first Bluetooth switch and the second Bluetooth switch; if the first Bluetooth switch is in the on state and the second Bluetooth switch is in the off state, turning on the second Bluetooth switch to establish a Bluetooth connection with the first Bluetooth device.

[0354] Exemplarily, step S2503b includes: in response to receiving a selection instruction for the first option, obtaining the status of the first Bluetooth switch and the second Bluetooth switch while maintaining the first application visible; if the first Bluetooth switch is in the on state and the second Bluetooth switch is in the off state, turning on the second Bluetooth switch to establish a Bluetooth connection with the first Bluetooth device.

[0355] Exemplarily, step S2503b includes: in response to receiving a selection instruction for the first option, while maintaining the operation guidance page, obtaining the status of the first Bluetooth switch and the second Bluetooth switch; if the first Bluetooth switch is in the on state and the second Bluetooth switch is in the off state, turning on the second Bluetooth switch to establish a Bluetooth connection with the first Bluetooth device.

[0356] In some embodiments, step S2503 includes: in response to receiving a selection instruction for the first option, while maintaining the first application from exiting (such as maintaining the first application running in the foreground, or maintaining the first application visible, or maintaining the operation guide page), controlling the first application to send an acquisition instruction for acquiring the status of the first Bluetooth switch and the second Bluetooth switch to the Bluetooth switch setting module; in response to the acquisition instruction, controlling the Bluetooth switch setting module to send a feedback instruction indicating the status of the first Bluetooth switch and the second Bluetooth switch to the first application, and controlling the Bluetooth switch setting module to record the current status of the first Bluetooth switch and the second Bluetooth switch; in response to the feedback instruction indicating that the first Bluetooth switch is in an on state and the second Bluetooth switch is in an off state, controlling the first application to send a Bluetooth on instruction to the Bluetooth switch setting module; in response to the Bluetooth on instruction, controlling the Bluetooth switch setting module to turn on the second Bluetooth switch; controlling the first application to send a register Bluetooth status broadcast instruction and a receive mode switch instruction to the Bluetooth module; in response to the register Bluetooth status broadcast instruction and the receive mode switch instruction, the Bluetooth module controls the Bluetooth driver to turn on the receive mode switch, and broadcasts the device information of the display device to enable the Bluetooth module to enter sink mode.

[0357] In the music playing method provided in the embodiment of the present application, the display device can turn on the second Bluetooth switch to establish a Bluetooth connection between the display device and the first Bluetooth device while maintaining the first application running in the foreground, maintaining the first application visible, or maintaining the operation guide page. Moreover, during the process of establishing the connection between the display device and the first Bluetooth device, the first application is never exited, so that after the Bluetooth connection is established between the display device and the first Bluetooth device, the first audio data sent by the first Bluetooth device can be played while the first application displays the first picture, so that the user can select the corresponding audio according to his or her preferences while appreciating the art painting.

[0358] S2504: While the first application is displaying the first picture, receiving and playing the first audio data sent by the first Bluetooth device.

[0359] It should be noted that step S2504 is similar to step S2204 in the above embodiment and will not be described again here to avoid repetition.

[0360] In some embodiments, after step S2504, the method further includes: in response to receiving an exit instruction for the first application, restoring the first Bluetooth switch and the second Bluetooth switch to a default state.

[0361] In some examples, 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 of the display device 200 in scenarios other than using the application Bluetooth music function. The default state of the second Bluetooth switch can be an on state or an off state. 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 an off state; or, 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 an on state.

[0362] Exemplarily, upon receiving an exit instruction from the first application, it is necessary to restore both the first Bluetooth switch and the second Bluetooth switch to a default state. For example, when the default states of the first Bluetooth switch and the second Bluetooth switch are both on, it is necessary to turn off the first Bluetooth switch and the second Bluetooth switch respectively. For another example, when the default states of the first Bluetooth switch and the second Bluetooth switch are both on, it is not necessary to adjust the first Bluetooth switch and the second Bluetooth switch. For another example, when the default state of the first Bluetooth switch is on and the default state of the second Bluetooth switch is off, it is necessary to maintain the on state of the first Bluetooth switch and turn on and off the second Bluetooth switch.

[0363] In the music playback method provided in the embodiment of the present application, when the first application is running in the foreground, the states of the first Bluetooth switch (i.e., the system Bluetooth switch) and the second Bluetooth switch (i.e., the visibility switch) may have changed (e.g., both the first Bluetooth switch and the second Bluetooth device are adjusted from the off state to the on state, or the second Bluetooth device is adjusted from the off state to the on state). In order to avoid affecting the performance of the display device, after the first application is exited, the first Bluetooth switch and the second Bluetooth switch may be restored to the default state.

[0364] The device state of the display device 200 may include an awake state and a dormant state. In the awake state, the display 260 is in a bright screen state, and the display device 200 has a high power consumption; in the dormant state, the display 260 is in a dark screen state, saving power consumption.

[0365] Fig.26A A schematic diagram of another music playing method provided in an embodiment of the present application is shown as follows: Fig.26A As shown, after the controller receives and plays the first audio data sent by the first Bluetooth device while the first application displays the first picture (such as the above step S2204 or step S2504), the method further includes the following steps:

[0366] S2601. When the fourth mode switch is in the on state, obtain the first brightness information of the environment in which the display device is located at the first moment. If the first brightness information is lower than the brightness threshold, and the brightness information within the third preset time period starting from the first moment is lower than the brightness threshold, display the screen off prompt information, start the first timing, and obtain the second brightness information.

[0367] In some examples, the first application may be configured with a fourth mode, wherein the fourth mode may also be referred to as a night mode. The fourth mode is used to automatically enter a sleep state when the ambient brightness is low. The state of the fourth mode may include an on state and an off state. For example, the user may select the on item of the fourth mode in the switch setting item of the first application through the control device 100 (such as a remote controller) to turn the fourth mode switch on.

[0368] Exemplarily, when the fourth mode switch is in the on state, the brightness information of the environment in which the display device 200 is located can be detected by the detector 230, and according to the brightness information, it is determined whether the display device 200 triggers the sleep state. Among them, the detector 230 can be a light intensity sensor or a light sensor. The light sensor can use its own photosensitive element to determine the specific brightness of the ambient light based on the internal photoelectric effect (that is, when light is irradiated on the photosensitive material, its internal resistivity changes, thereby generating an electromotive force).

[0369] For example, the light intensity sensor can detect the brightness (first brightness information) of the environment in which the display device 200 is located at the current moment (such as the first moment), compare the detected first brightness information with the brightness threshold, and continue to obtain the brightness information of each moment within the third preset time period starting from the first moment when the first brightness information is lower than the brightness threshold. When the brightness information obtained at any moment within the third preset time period is lower than the brightness threshold, the display is controlled to display the screen off prompt information. Among them, the brightness threshold and the third preset time period can be set according to needs, such as the third preset time period can be 1 minute, 5 minutes, or a time period set according to user needs.

[0370] In some examples, the screen off prompt information is used to prompt the user that the screen is about to be turned off, or to prompt the user to enter the screen off timer. For example, the screen off prompt information may include a first timer. The first timer may be a countdown or a countdown, which is not limited in the embodiments of the present application.

[0371] S2602: If the second brightness information is lower than the brightness threshold before the first timing reaches a fourth preset duration, after the first timing reaches the fourth preset duration, pause the playing of the first picture, control the display to turn off the screen, and control the audio output device to mute.

[0372] In some examples, during the first timing, the display device 200 continuously detects the ambient brightness. Before the first timing reaches the fourth preset duration, if the display device 200 detects that the brightness (such as the second brightness information) is lower than the brightness threshold, the display device 200 is triggered to enter a dormant state, pause the first image, control the display to turn off the screen, and control the audio output device to mute.

[0373] In some examples, the fourth preset duration may be the same as the third preset duration, or may be different from the third preset duration. For example, the fourth preset duration may be less than the third preset duration, such as the third preset duration may be 30 seconds. Before the first timing reaches the fourth preset duration, that is, within 30 seconds of entering the forward timing or countdown, the brightness of the environment in which the display device 200 is located continues to be lower than the brightness threshold, indicating that the user may be in rest time. Therefore, in order to reduce the energy consumption of the display device, after the first timing reaches the fourth preset duration, the display device 200 can be controlled to enter a sleep state.

[0374] The music playing method provided in the embodiment of the present application can determine whether to trigger the sleep state of the display device according to the brightness information of the environment in which the display device is located detected by the detector when the display device turns on the fourth mode (such as night mode). When the display device enters the sleep state, the first picture is paused, the display is turned off, and the audio output device is muted. In other words, the present application can enter the sleep state when the brightness information of the environment in which the display device is located is continuously low, thereby reducing the power consumption of the display device.

[0375] S2603. If there is second brightness information higher than the brightness threshold before the first timing reaches the fourth preset duration, stop the first timing and cancel the display of the screen off prompt information.

[0376] For example, if the display device 200 detects brightness information higher than the brightness threshold before the first timing reaches the fourth preset duration, the first timing is stopped and the screen-off prompt information is cancelled. For example, within 30 seconds (i.e., the fourth preset duration) of the countdown (or forward timing), the display device 200 continuously detects the brightness of the environment in which the display device 200 is located, and only when the brightness at a certain moment is detected to be higher than the brightness threshold, the countdown is stopped.

[0377] For example, after stopping the first timing, the display device 200 may continue to detect the ambient brightness and compare the detected brightness information with the brightness threshold, that is, continue to execute the above steps 2601 to SS2603.

[0378] Based on the above scheme, if the second brightness information of the environment in which the display device is located is higher than the brightness threshold before the first timing reaches the fourth preset time, the first timing is stopped and the screen-off prompt information is canceled. In other words, the present application can continue to display the first picture normally when the brightness information of the environment in which the display device is located is higher than the brightness threshold, thereby not affecting the user's continued appreciation of the art painting.

[0379] S2604: If the third brightness information obtained at the second moment is higher than the brightness threshold, and the brightness information within the fifth preset time period starting from the second moment is higher than the brightness threshold, control the display to light up the screen, unmute the audio output device, and continue to display the first picture in the first application.

[0380] In some examples, after the display device 200 enters the sleep state, the display device 200 can continue to detect the brightness of the environment in which it is located. If, at the second moment after entering the sleep state, the third brightness information of the environment in which the display device 200 is located is obtained to be higher than the brightness threshold, then starting from the second moment, the brightness information within the fifth preset time period continues to be higher than the highlight threshold, and the display device 200 is controlled to enter the wake-up state, that is, the display is controlled to light up, the audio output device is muted, and the first image continues to be displayed in the first application.

[0381] For example, the second moment is the moment when the brightness information of the environment is higher than the brightness threshold for the first time after the display device enters the sleep state. The fifth preset time length and the target preset time length can be set according to user needs. For example, the fifth preset time length can be the same as the third preset time length, or can be different from the third preset time length.

[0382] In some examples, when the brightness information within the fifth preset duration starting from the second moment is higher than the brightness threshold, the display device 200 can gradually restore the display brightness and the volume of the audio output device to the awake state before the sleep state within the target duration. In this case, the display brightness of the display 260 can have a transition process from low to high, effectively reducing the stimulation of the state switching of the display 260 on the user's vision; at the same time, the volume value of the audio output device 270 has a transition process from low to high, which can also effectively reduce the stimulation of the state switching of the audio output device 270 on the user's hearing. Among them, the target preset duration can be set to 5 seconds, which is not limited in the embodiment of the present application.

[0383] Based on the above scheme, after the display device enters the sleep state, if it detects that the brightness information within a period of time (such as the fifth preset time) is higher than the brightness threshold, it can exit the sleep mode, enter the wake-up state, control the display to light up, unmute the audio output device, and continue to display the first picture in the first application. In other words, this application can automatically switch from the sleep mode to the wake-up mode when the brightness information of the environment in which the display device is located is higher than the brightness threshold, and continue to display the first picture, thereby ensuring that the user can continue to appreciate the art painting and improve the user experience.

[0384] In some examples, when the display device turns on the fourth mode, the embodiment of the present application can continuously monitor the brightness of the environment (such as light intensity) through the light intensity sensor of the display device 200, and determine whether it is night or low light environment according to the brightness. When the display device is in the art mode display process, if the brightness of the environment is higher than the preset screen-on threshold, the display device will maintain the normal screen-on display state; if the brightness of the environment drops below the screen-on threshold, and no other light source is detected within a certain time (i.e., the third preset duration), the dormant state of the display device will be triggered, and the display device can start a fourth preset duration (such as 30 seconds). During the timing process, if the brightness of the environment rises above the screen-on threshold again, the timing will be interrupted, the display device will resume the screen-on and continue the art mode display. During the timing process, if the brightness of the environment is always lower than the screen-on threshold, the display device 200 will enter the dormant state after the timing ends, the display will turn off the screen, and the volume will be muted to save energy and reduce the impact on the user's sleep. After the display device enters the sleep state, the light intensity sensor remains working. Once it detects that the ambient light brightness reaches the screen-on threshold again, the display device will automatically turn on the screen, unmute the sound, and gradually restore to the previously set brightness and volume levels within a certain period of time (such as within 5 seconds) so that the user can continue to watch or interact seamlessly.

[0385] Fig.26B FIG. 4 is a flow chart of the internal interaction of the display device 200 in the fourth mode according to some embodiments. Fig.26B As shown, the ArtMode Settings module sets the night mode (i.e., the fourth mode) switch, and the ArtModeService module obtains the night mode switch status from the ArtMode Settings module and determines whether the night mode switch is turned on. The light sensor collects the light in the environment where the display device is located, and the ArtModeService module reads the detected light brightness value from the light sensor and determines the relationship between the light brightness value and the preset brightness value.

[0386] When it is determined that the light brightness value is lower than the preset brightness value and lasts for 10s, the countdown is started. When the countdown is reached and the light brightness is lower than the preset brightness, the ArtModeService module sends a notification to unmute the AudioManager module to enable the AudioManager module to unmute the audio output device; and sends a poweron notification to the PowerManager module to enable the PowerManager module to control the display to start and light up the screen.

[0387] The light sensor continues to collect light from the environment in which the display device is located. The ArtModeService module reads the detected light brightness value from the light sensor. When the light brightness value collected by the light sensor is higher than the preset brightness and lasts for 10s, the ArtModeService module sends a notification to unmute the AudioManager module to enable the AudioManager module to unmute the audio output device; and sends a power on notification to the PowerManager module to enable the PowerManager module to control the display to start up and turn on the screen.

[0388] Fig. 27 A schematic diagram of another music playing method provided in an embodiment of the present application is shown as follows: Fig. 27 As shown, after the controller receives and plays the first audio data sent by the first Bluetooth device while the first application displays the first picture (such as the above step S2204 or step S2504), the method further includes the following steps:

[0389] S2701: When the fifth mode switch is in the on state, detect moving objects around the display device.

[0390] In some examples, the first application may also be configured with a fifth mode, wherein the fifth mode may also be referred to as a motion mode or a motion detection mode. When the fifth mode is turned on, a moving object in the environment where the display device 200 is located may be detected, and based on the detection result, it is determined whether the display device 200 triggers a sleep state. When it is determined that the sleep state is triggered, the display device is controlled to turn off the screen and mute the sound, thereby reducing the power consumption of the display device 200 and extending the service life of the display device 200.

[0391] For example, the state of the fifth mode may include on and off, and the user may select the on item in the switch setting item of the motion mode through the control device 100 (such as a remote controller) to turn on the fifth mode switch.

[0392] In some examples, when the fifth mode switch is in the on state, the display device 200 can perform motion detection through the motion detection sensor. The motion detection sensor can send detection data to the controller, and the controller determines whether a moving object is detected in the environment where the display device 200 is located according to the detection data.

[0393] For example, the motion detection sensor can be a millimeter wave sensor, which uses an antenna to transmit millimeter wave signals. Among them, millimeter wave signals have the characteristics of high frequency, short wavelength, high resolution and strong penetration, and can be effectively propagated in the environment. When the millimeter wave signal encounters an object (such as a moving object), reflection, scattering or transmission will occur, and the receiver on the millimeter wave sensor will capture these reflected, scattered or transmitted signals. By analyzing and processing the received signals, the size, shape, material, surface texture and other information of each moving object can be determined, thereby determining whether there are moving objects in the environment where the display device is located.

[0394] S2702: If no moving object is detected within a sixth preset time period, control the display to turn off the screen and control the audio output device to mute.

[0395] Exemplarily, when the display device 200 is in the awake state (screen on and not muted), the motion detection sensor of the display device 200 detects the surrounding environment. If no moving object is detected within the sixth preset time period starting from the current moment, the sleep state of the display device 200 is triggered, the display is controlled to turn off the screen, and the audio output device is controlled to mute.

[0396] In some examples, timing can start when the motion detection sensor starts detection. If the motion detection sensor has not detected a moving object before the timing reaches a sixth preset time, the display device 200 is triggered to enter a sleep state (i.e., the screen is turned off and the sound is muted) after the timing reaches the sixth preset time.

[0397] In some examples, if the motion detection sensor detects a moving object before the timing duration reaches the sixth preset duration, the display device 200 remains in the awake state, starts a new round of detection, and restarts the timing. For example, if the motion detection sensor detects a moving object within the sixth preset duration, it indicates that there may be user activities around the display device 200, that is, the first picture still needs to be displayed to the user. Therefore, the display device 200 needs to remain awake.

[0398] Based on the above scheme, by detecting moving objects in the environment where the display device is located when the fifth mode switch is in the on state, if no moving objects are detected around the display device within a certain period of time (such as the sixth preset period of time), the display device can be adjusted to a sleep state, thereby reducing the power consumption of the display device and extending the service life of the display device.

[0399] S2703: In response to detecting a moving object around the display device, or in response to receiving a command input through a remote controller, controlling the display to light up, unmuting the audio output device, and continuing to display the first picture in the first application.

[0400] In some examples, after the display device 200 enters the sleep state, the motion detection sensor of the display device 200 continues to detect moving objects. When a moving object is detected, the display device 200 is re-triggered to enter the wake-up state, that is, the display device 200 needs to switch from the sleep state to the wake-up state. In this case, the display can be controlled to light up the screen, the audio output device can be unmuted, and the first picture can continue to be displayed in the first application.

[0401] In other examples, after the display device 200 enters the sleep state, the display device 200 may also be controlled to enter the wake-up state by responding to a corresponding command input by a control device (such as a remote controller). For example, the user may adjust the display device 200 to the wake-up state by inputting a command by pressing a preset button on the remote controller. The preset button may be a power button, a first mode button, a return button, etc., which is not limited in the embodiments of the present application.

[0402] For example, after the display device 200 re-enters the awake state, the display brightness and the volume of the audio output device can be gradually restored to the awake state before the sleep state within the target duration. In this case, the display brightness of the display 260 has a transition process from low to high, which can effectively reduce the visual stimulation of the user caused by the state switching of the display 260; at the same time, the volume value of the audio output device 270 has a transition process from low to high, which can also effectively reduce the auditory stimulation of the state switching of the audio output device 270.

[0403] Based on the above scheme, when the display device enters the sleep state, if it detects that there is a moving object in the environment where the display device is located, or receives a command from the user to exit the sleep mode, it can exit the sleep mode and enter the wake-up mode, control the display to light up, unmute the audio output device, and continue to display the first picture in the first application. In other words, this application can automatically switch from the sleep mode to the wake-up mode when there is a moving object in the environment where the display device is located, and continue to display the first picture, thereby ensuring that the user can continue to appreciate the art painting and improve the user experience.

[0404] In some embodiments, after step S2702, the method further includes: when the fourth mode switch and the fifth mode switch are both in the on state, in response to detecting the presence of a moving object around the display device, and the brightness of the environment in which the display device is located is higher than a brightness threshold, controlling the display to light up the screen, unmuting the audio output device, and continuing to display the first picture in the first application.

[0405] In some examples, if the fourth mode switch and the fifth mode switch are both in the on state, then after the display device 200 enters the sleep state, the display device 200 needs to be triggered to re-enter the wake-up state only when the motion detection sensor detects that there are moving objects around the display device 200 and the light intensity sensor detects that the brightness of the environment in which the display device 200 is located is higher than the brightness threshold.

[0406] In some examples, after the display device 200 enters the sleep state, if there is no moving object around the display device 200, and / or the brightness of the environment in which the display device 200 is located is lower than the brightness threshold, the display device remains in the sleep state. For example, when the motion detection sensor does not detect a moving object within the sixth preset time period, but the brightness of the environment in which the display device 200 is located is greater than the brightness threshold, the display device 200 will remain in the sleep state; or, when the motion detection sensor detects a moving object within the sixth preset time period, but the brightness of the environment in which the display device 200 is located is lower than the brightness threshold, the display device 200 will also remain in the sleep state.

[0407] Based on the above scheme, when the fourth mode and the fifth mode set by the first application are both turned on, if the display device enters a sleep state, the display device will be triggered to re-enter the wake-up state only when it detects that there are moving objects around the display device and detects that the brightness of the environment in which the display device is located is higher than the brightness threshold. After the display device enters the wake-up state, the display screen lights up, the audio output device is unmuted, and the first application continues to display the first picture, thereby ensuring that the user can continue to appreciate the art painting and improving the user experience.

[0408] In some embodiments, the display device 200 may also be configured with a second application. The second application is used to play audio, and may also be referred to as an audio player application. The second application is an application that uses the system Bluetooth function and is in an audio receiving mode when using the system Bluetooth function.

[0409] After opening the second application, the display device 200 will enter the second mode. In the second mode, the display device 200 will act as an audio receiving device, equivalent to a speaker, for receiving and playing audio sent by other Bluetooth devices. Among them, the second application can also be called a speaker application, a speaker mode application, my music application, etc. The second mode can also be called a speaker mode, my music mode, etc.

[0410] 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.

[0411] In some embodiments, the display device 200 may be configured to Fig.28 The process shown enters the speaker mode. The specific steps are as follows:

[0412] S2801, 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.

[0413] In some embodiments, the control device 100 may be configured with a key dedicated to opening a 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.

[0414] In some embodiments, the display device 200 may set an icon of the speaker mode application in the main page, the sidebar and / or the shortcut menu. The display device 200 may enter the speaker mode application in response to an instruction by the user to select the icon of the speaker mode application.

[0415] 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 be used as an audio receiving device in the speaker mode. After pairing and connecting with other Bluetooth devices, it can receive and play the audio sent by other Bluetooth devices.

[0416] In some embodiments, after entering the speaker mode application, the display device 200 can refer to step S1201 to turn on the first Bluetooth switch, the second Bluetooth switch, and the third Bluetooth switch to ensure the availability of the system Bluetooth function and to be discovered by non-specified Bluetooth devices, thereby ensuring that the speaker mode is available. When exiting the speaker mode or disconnecting from the Bluetooth device, the first Bluetooth switch, the second Bluetooth switch, and the third Bluetooth switch are restored to their default states, which will not be described in detail here.

[0417] The operation guide page in speaker mode can refer to the operation guide page in art mode, which will not be repeated here.

[0418] S2802: Display a pairing page according to the pairing request of the first Bluetooth device.

[0419] S2803, in response to the user's instruction to agree to pairing, pairing with the first Bluetooth device, and displaying a prompt page after pairing with the first Bluetooth device is successful.

[0420] Steps S2802-S2803 can refer to steps S1202-S1203 and are not repeated here.

[0421] 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, and will not be repeated here.

[0422] In some embodiments, the display device 200 may automatically exit the prompt page after a first period of time.

[0423] In some embodiments, the display device 200 may exit the prompt page in response to an instruction input by the user based on a back key of the control device 100 .

[0424] After exiting the prompt page, if the first Bluetooth device is not in the playing state, a waiting page may be displayed, which may be a default page of the speaker mode, for prompting the user to wait for the music to be played.

[0425] S2804: After receiving the first audio sent by the first Bluetooth device, display a music playing page and play the first audio.

[0426] In some embodiments, if the user uses the first Bluetooth device to play the first audio, the first Bluetooth device can send a play notification and the first audio to the display device 200. The display device 200 can determine that the first Bluetooth device is in the audio playing state according to the play notification, and after determining that the first Bluetooth device is in the audio playing state, exit the prompt page and display the music playing page.

[0427] 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.

[0428] In some embodiments, the display device 200 displays device playback information on the music playback page, and the device playback information may include a device name and a device icon of the first Bluetooth device, where the device icon is used to identify a device type of the first Bluetooth device.

[0429] You can refer to Fig.29 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.

[0430] In some embodiments, the music playback page may include audio information, a playback progress bar, playback controls, lyrics, a spectrum analysis graph, and the like.

[0431] The audio information includes relevant information of the first audio currently being played, such as the audio name, audio introduction, etc. Fig.29 , the relevant information of the first audio includes the audio name, such as AAAA, and the singer: BBBB.

[0432] The playback progress bar is used to indicate the total duration of the first audio and the current playback duration. Fig.29 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 duration of the play, such as 1 minute and 6 seconds.

[0433] 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. Fig.29 The music playing page shown in FIG. 1 includes a forward switching control 2302 and a backward switching control 2303. When the current audio is in the playing state, the playing control may also include a pause playing control for pausing the playing of the current audio. Fig.29 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 an open play control for opening the current audio. Fig.29 The music playback page shown includes opening the playback control. In some embodiments, the display device 200 sends a control instruction to the first Bluetooth device in response to the user's instruction to select 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 according to the information about the playback control. For example, the control instruction includes information about the forward switch control, and the first Bluetooth device switches to playing the previous audio and sends the previous audio to the display device 200 to achieve the effect of switching to playing the previous audio on the display device 200.

[0434] 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. Fig.29 The music playback page shown displays the corresponding lyrics, such as CCCCCCCC, when the playback progress is 1 minute and 6 seconds.

[0435] The spectrum analysis graph is used to show the frequency distribution and volume changes of the current audio, which can increase the interest of audio playback. Fig.29 The music playing page shown includes a spectrum analysis diagram 2305 of the first audio.

[0436] In some embodiments, if the display device 200 is currently playing the second audio, then 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. The process of muting the second audio in the speaker mode can refer to the process of muting the second audio in the art mode, which is not repeated here.

[0437] In some embodiments, in the speaker mode, the display device 200 can be connected to the first Bluetooth device and the second Bluetooth device at the same time, and the number of the second Bluetooth device is at least 1. At this time, the display device 200 can switch the Bluetooth device that provides audio. Fig.30 The process shown switches the Bluetooth device that provides audio. The specific steps are as follows:

[0438] S3001, in response to a user's control instruction, display a list of connected devices on a music playback page.

[0439] In some embodiments, the speaker mode application can configure a list button on the music playback page, which is an entry to the list of connected devices. Fig.29 The music playing page shown may include a list button 2306. The user may input a control instruction by selecting the list button to instruct the display device 200 to open a list of connected devices.

[0440] In response to the control instruction, the display device 200 displays a connected device list on the music playing page, and the connected device list includes items of currently connected Bluetooth devices. Fig.31 The music playing page shown in the figure displays a connected device list 2501. If the currently connected Bluetooth devices include a first Bluetooth device, such as a device named my phone, and a second Bluetooth device, such as a device named living room TV, then the connected device list 2501 includes items of my phone and living room TV.

[0441] S3002, in response to an instruction from a user to select an item of a second Bluetooth device, stop receiving the first audio from the first Bluetooth device, and start receiving the third audio sent by the second Bluetooth device.

[0442] S3003: After receiving the third audio sent by the second Bluetooth device, play the third audio.

[0443] Steps S3002-S3003 may refer to steps S1902-S1903 and are not described in detail here.

[0444] When determining that the second Bluetooth device is in an audio playing state, the display device 200 displays a 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.

[0445] In some embodiments, the display device 200 may be configured to unmute the second audio when it detects that the currently used Bluetooth device pauses playing audio, or detects that the currently used Bluetooth device is disconnected. Disconnecting from the currently used Bluetooth device may include: the currently used Bluetooth device is disconnected from the display device 200, or the display device 200 exits the art mode application, etc. The above process can refer to the corresponding process in the art mode, which is not repeated here.

[0446] In some embodiments, the speaker mode application can also turn off the screen to play audio, and the display device 200 can Fig.32 The process shown adjusts the status of the display screen. The specific steps are as follows:

[0447] S3201, in response to the user's screen-off instruction, adjusting the display screen to a screen-off state and keeping playing the first audio.

[0448] In some embodiments, the speaker mode application may be configured with a screen-off button in the music playback page. The user may input a screen-off instruction by selecting the screen-off button.

[0449] 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 will no longer display the picture, and will play the audio as a simple speaker to avoid disturbing the user by displaying the picture.

[0450] S3202, in response to the user's screen-on instruction, adjust the display screen to a screen-on state and keep playing the first audio.

[0451] 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, in this process, the first audio is always played to avoid affecting the user's auditory enjoyment.

[0452] 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.

[0453] However, both the art mode application and the speaker mode application are configured to switch the display device 200 back to the source mode when exiting the application. Therefore, after exiting the application, the display device 200 will not be able to receive the audio provided by the audio sending device as an audio receiving device, and will not be able to continue playing the audio. In other words, when the display device 200 plays audio as an audio receiving device, if it switches between the art mode and the speaker mode, it will inevitably switch to the source mode due to exiting the current application, thereby disconnecting the connection with 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 the art mode and the speaker mode, the continuity of music playback cannot be guaranteed, resulting in a poor effect of combining the art mode and the speaker mode.

[0454] 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, the 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 in an on state and locking the sink mode. In other words, the art mode application is an application that needs to keep the first Bluetooth switch in an on state and keep the Bluetooth mode in an audio receiving mode when switching from the speaker mode application. The speaker mode application is an application that needs to keep the first Bluetooth switch in an on state and keep the Bluetooth mode in an audio receiving mode when switching from the art mode application.

[0455] In some embodiments, the display device 200 may be configured to Fig.33A The process shown is to switch from speaker mode to art mode. The specific steps are as follows:

[0456] S3301, in speaker mode, in response to a user's switching instruction, identifying a target application after switching.

[0457] Based on step S2801, it can be known that after entering the speaker mode application, the display device 200 automatically switches to the sink mode. In the speaker mode, the currently connected first audio device may be in an audio playback state or may not be in an audio playback state, or, in the speaker mode, the display device 200 may not be connected to a Bluetooth device. In other words, as long as it is in the speaker mode, the display device 200 is in the sink mode.

[0458] If the user wants to use the target application, the target application can be opened through a switching instruction.

[0459] 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.

[0460] In some embodiments, the display device 200 may be configured with an icon of 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 of the art mode application. In the 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. Fig.33B 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. Fig.33B 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.

[0461] In some embodiments, based on the way of starting the art mode, the user can input a switching instruction by short pressing the power button.

[0462] In response to the switching instruction, the display device 200 switches the page displaying the target application.

[0463] 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, it can be determined that the target application is an art mode application. If the top activity is not identified as art mode, it can be determined that the target application is not an art mode application but another application.

[0464] In other embodiments, the display device 200 can identify the target application by monitoring key events. Based on a key event for starting an art mode application, such as an art mode key event, a power key event, or an OK key event based on an icon of an art mode application, if the monitored key event is a first specified key event, such as an art mode key event, a power key event, or an OK key event based on an icon of an art mode application, it can be determined that the target application is 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 icon of an art mode application, it can be determined that the target application is not an art mode application, but another application.

[0465] S3302: 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.

[0466] If the target application is an art mode application, 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 the 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.

[0467] 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 a 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 key, the art mode key, or selecting the icon of the art mode application in the sidebar / shortcut menu. After entering the art mode, the display device 200 will display the display page of the art mode application and display the art paintings in the display page. After the display device 200 recognizes that the switched application is an art mode application, the system Bluetooth function is locked in the on state and locked in sink mode. In this way, the display device 200 can always remain connected to the first Bluetooth device and receive the first audio sent by the first Bluetooth device during the process of switching to art mode, that is, the continuous playback of the first audio can be guaranteed.

[0468] In some embodiments, in the speaker mode, the display device 200 is in the sink mode. If the display device 200 is not connected to a Bluetooth device, after switching to the art mode, the lock system Bluetooth function is turned on and the lock is in the sink mode. In the art mode, the display device 200 can directly pair and connect with the first Bluetooth device in response to the user's operation of turning on the application Bluetooth music function without switching modes.

[0469] In some embodiments, after switching to the art mode, if it is detected that the first Bluetooth device is currently connected and the first Bluetooth device is in an audio playback state, the device playback information of the first Bluetooth device can be displayed on the display page, and after a preset time, the device playback information can be hidden. In this way, after switching modes, the user can be prompted with the Bluetooth device currently in use.

[0470] S3303: If the target application is not an art mode application, restore the default state of the first Bluetooth switch, and switch the Bluetooth mode from the audio receiving mode back to the audio sending mode.

[0471] If the switched application is not an art mode application, it means that the display device 200 is not currently in the speaker mode or the art mode, which is equivalent to directly exiting the speaker mode, and the display device 200 restores the default state of the system Bluetooth function and switches back to the source mode.

[0472] In some embodiments, the display device 200 may be configured to Fig.34 The process shown is to switch from speaker mode to art mode. The specific steps are as follows:

[0473] S3401, in the art mode, in response to a user's switching instruction, identifying a target application after switching, and identifying whether the Bluetooth mode is in an audio receiving mode.

[0474] In some embodiments, the display device 200 switches to 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 is not connected to the Bluetooth device, if the display device 200 displays the operation guide page or the pairing page, the display device 200 is in 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 source mode. After the display device 200 establishes a connection with the Bluetooth device, it remains in sink mode. If the display device 200 disconnects after establishing a connection with the Bluetooth device, it will switch back to sink mode.

[0475] If the user wants to use the target application, the target application can be opened through a switching instruction.

[0476] Taking the target application as a speaker mode application as an example, in some embodiments, the user can input a switching instruction through a key dedicated to the speaker mode on the control device 100, such as the music key, to instruct the display device 200 to open the speaker mode application.

[0477] In some embodiments, the display device 200 may be configured with an icon of the speaker mode application in the 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 of the art mode application. In the 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. Fig.33B 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. Fig.33B 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 may include an icon of the speaker mode application.

[0478] In response to the switching instruction, the display device 200 switches the page displaying the target application.

[0479] 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 (speaker mode application), it can be determined that the target application is a speaker mode application. If the top activity is not my music, it can be determined that the target application is not a speaker mode application but another application.

[0480] In other embodiments, the display device 200 can identify the target application by monitoring key events. Based on the key event of starting the speaker mode application, such as the music key event, the OK key event based on the icon of the speaker mode application, if the monitored key event is a second specified key event, such as the music key event or the OK key event based on the icon of the speaker mode application, it can be determined that the target application is the speaker mode application. If the monitored key event is not the music key event and the OK key event based on the icon of the speaker mode application, it can be determined that the target application is not the speaker mode application, but other applications.

[0481] S3402: 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.

[0482] If the target application is a speaker mode application, 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 the 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.

[0483] In some embodiments, in art mode, the display device 200 is in sink mode. If the display device 200 connects to the first Bluetooth device based on the application 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 playback of the first audio through the display device 200, it can switch to the speaker mode, such as pressing the music key or selecting the icon of the speaker mode application in the sidebar / shortcut menu. After the display device 200 recognizes that the switched application is a speaker mode application, the system Bluetooth function is locked in the on state and locked in sink mode. In this way, the display device 200 can always remain connected to the first Bluetooth device and receive the first audio sent by the first Bluetooth device during the process of switching to the speaker mode, that is, the continuous playback of the first audio can be guaranteed. In speaker mode, the display device 200 will display the music playback page, and display the audio information of the first audio in the music playback page.

[0484] In some embodiments, in the art mode, the display device 200 is in the sink mode, but has not yet connected to the Bluetooth device, such as when displaying the operation guide page or the pairing page, after switching to the speaker mode, the system Bluetooth function is locked in the on state and locked in the sink mode. In the speaker mode, the display device 200 can be directly paired and connected with the first Bluetooth device without switching modes.

[0485] In some embodiments, after switching to the speaker mode, if it is detected that the first Bluetooth device is currently connected, the device playback information of the first Bluetooth device can be displayed on the music playback page. Thus, after switching the mode, the user can be prompted with the Bluetooth device currently being used.

[0486] S3403: If the target application is not a speaker mode application, restore the default state of the first Bluetooth switch, and switch the Bluetooth mode from the audio receiving mode back to the audio sending mode.

[0487] If the switched application is not a speaker mode application, it means that the display device 200 is not currently in the art mode or the speaker mode, which is equivalent to directly exiting the art mode, and the display device 200 restores the default state of the system Bluetooth function and switches back to the source mode.

[0488] In some embodiments, the display device 200 can manage the start and stop of the system Bluetooth function and the switch between source mode and sink mode through the BluetoothSinkManager class. Taking the method of identifying the target application by identifying the top activity as an example, the method of determining the current topactivity can be encapsulated in the BluetoothSinkManager class. MyMusicActivity and ArtModeActivity respectively start the Sink mode in the onCreate method, and determine whether the Sink mode needs to be stopped according to the TopActivity in the onStop method.

[0489] In combination with the above embodiments, the present application may also provide another music playing method, which can ensure continuous audio playback when switching between different applications. Fig.35A A schematic diagram of another music playing method provided in an embodiment of the present application is shown as follows: Fig.35A As shown, the method comprises the following steps:

[0490] S3501. In response to receiving a start instruction for a first application, start the first application.

[0491] S3502: When displaying a first picture on a display page of a first application, if a Bluetooth connection is established between the display device and a first Bluetooth device, first audio data sent by the first Bluetooth device is received and played while the first application displays the first picture.

[0492] The first application is at least used for playing pictures. It should be noted that steps S3501 to S3502 have been described in detail in the above embodiment (such as steps S2201 to S2204, and steps S2501 to S2505), and will not be repeated here to avoid repetition.

[0493] S3503: In response to receiving an application switching instruction to switch from the first application to the second application, start the second application and determine the Bluetooth mode of the display device.

[0494] Among them, the second application is an audio player application. For example, the second application can be a speaker application, a speaker mode application, a my music application, etc. The embodiment of the present application does not limit the type of the second application.

[0495] In some examples, the first mode (i.e., art mode) of the first application and the mode (e.g., speaker mode) of the second application can be switched. For example, the user can input a switching instruction through a preset speaker mode button (e.g., music button) on the control device 100 (e.g., remote controller) to instruct the display device 200 to open the second application and enter the speaker mode. Alternatively, the user can also input a switching instruction by pressing a button on the remote controller to select a preset control in the application interface of the first application (e.g., a control to start the second application, or an icon of the second application). Alternatively, the user can also input a switching instruction through voice input, etc., which is not limited in the embodiments of the present application.

[0496] For example, the display device 200 can start the second application in response to the switching instruction and determine the Bluetooth mode of the display device. Wherein, the Bluetooth mode includes an audio source mode (hereinafter referred to as source mode) and an audio receiving mode (hereinafter referred to as sink mode). When the display device 200 is in source mode, the display device 200 acts as an audio source device, and when the display device 200 is in sink mode, the display device 200 acts as an audio receiving device.

[0497] In some examples, when the display device 200 is in the first mode corresponding to the first application, the display device 200 may be in a sink mode or a source mode.

[0498] S3504: If the Bluetooth mode of the display device is the sink mode, maintain the first Bluetooth switch in the on state, and maintain the Bluetooth mode in the sink mode.

[0499] S3505: Receive first audio data sent by the first Bluetooth device, and continue to play the first audio data in the second application.

[0500] Exemplarily, when it is determined that the Bluetooth mode of the display device 200 is the sink mode, if a Bluetooth connection is established between the display device 200 and the first Bluetooth setting, then when the display device 200 displays the first picture and plays the first audio data provided by the first Bluetooth device, if the user wants to browse the audio information of the first audio data, and / or control the playback of the first audio through the display device 200, the first application can be switched to the second application. When the display device 200 recognizes that the switched application is the second application, the first Bluetooth switch can be locked in the on state, and the Bluetooth mode of the display device can be locked in the sink mode. In this case, the display device 200 can always maintain a connection with the first Bluetooth device and receive the first audio data sent by the first Bluetooth device during the process of switching to the second application, that is, to ensure the continuous playback of the first audio data.

[0501] In some examples, in the speaker mode corresponding to the second application, the display device 200 will display a music playback page and display audio information of the first audio in the music playback page.

[0502] For example, Fig.35B As shown, after the first application is started, while the first application displays the first picture, the first audio data sent by the first Bluetooth device is played (the implementation of this process can refer to Fig.23 ). In response to the control instruction of switching from the first application to the second application, the first application is exited and the second application is started. After the first application calls to turn off the Bluetooth music function (such as the BT music function), it sends a Bluetooth status broadcast to the Bluetooth module to release the registration of the first application, and the second application sends a Bluetooth status broadcast to the Bluetooth module to register the second application. After determining to switch to the second application, the first application does not issue an instruction to turn off the Bluetooth sink mode to maintain the first Bluetooth switch in the on state and maintain the Bluetooth mode in sink mode. The first Bluetooth device plays audio and sends the audio transmission instruction to the Bluetooth driver module via the A2DP protocol. The Bluetooth driver module receives the audio and sends a data transmission instruction to the Bluetooth module, instructing the Bluetooth module to play the audio. The second application receives the audio sent by the first Bluetooth device and continues to play the audio.

[0503] The music playback method provided in the embodiment of the present application avoids interruption of the audio data played during the switching from the first application to the second application by locking the first Bluetooth switch in the on state and maintaining the sink mode, thereby ensuring the continuity of the audio data playback during the application switching process and improving the user experience; and there is no need for frequent operations during the application switching process to ensure continuous playback of the audio data during the application switching process.

[0504] Fig.36 A schematic diagram of another music playing method provided in an embodiment of the present application is shown as follows: Fig.36 As shown, the method comprises the following steps:

[0505] S3601. In response to receiving a start instruction for a second application, start the second application.

[0506] In some examples, the control device 100 may be configured with a key for opening the second application (i.e., entering the speaker mode), such as a music key, and the display device 200 may start the second application and enter the speaker mode in response to the user's instruction input to the music key. For example, the display device 200 may set an icon of the second application (such as a speaker mode icon) on the main page, sidebar, and / or shortcut menu, and the display device 200 may enter the second application corresponding to the speaker mode in response to the user's instruction to select the speaker mode icon.

[0507] S3602: When the display device establishes a Bluetooth connection with the first Bluetooth device, receive first audio data sent by the first Bluetooth device, display a music playback interface on the second application, and play the first audio data.

[0508] In some examples, after entering the second application, the display device 200 can turn on the first Bluetooth switch and the second Bluetooth switch, display the pairing page after receiving the pairing request sent by the first Bluetooth device, and in response to the user's instruction to agree to the pairing, pair with the first Bluetooth device to achieve a Bluetooth connection with the first Bluetooth device.

[0509] In some examples, after the display device 200 establishes a Bluetooth connection with the first Bluetooth device, if the user plays the first audio data through the first Bluetooth device, the first Bluetooth device can send a play notification to the display device 200 and send the first audio data. When the display device 200 can determine that the first Bluetooth device is in an audio playing state according to the play notification, the music playing interface can be displayed in the second application and the first audio data can be played.

[0510] For example, the music playback interface may display playback device information, audio information, playback progress bar, playback controls, lyrics, spectrum analysis chart, etc. The playback device information may include the device name and device icon of the first Bluetooth device, and the device icon is used to identify the device type of the first Bluetooth device; the audio information may include the audio name and audio introduction of the first audio data currently being played.

[0511] S3603: In response to receiving an application switching instruction to switch from the second application to the first application, start the first application, maintain the first Bluetooth switch in an on state, and maintain the Bluetooth mode in a sink mode.

[0512] S3604: While the first application is displaying the first picture, receive and continue to play the first audio data sent by the first Bluetooth device.

[0513] In some examples, after entering the second application, the display device 200 can switch to sink mode. When the display device 200 starts the second application, if the user wants to use the first application, the first application can be opened through a switching instruction. For example, the user can input a switching instruction through a key dedicated to the first application on the control device 100, such as an art mode key, or the user can also input a switching instruction through voice to instruct the display device 200 to open the first application. Alternatively, the user can also open the first application through a control or icon for opening the first application on the playback interface of the second application.

[0514] Exemplarily, since the display device is in sink mode after starting the second application, there is no need to determine the Bluetooth mode of the display device after the display device 200 switches from the second application to the first application. In addition, in order to ensure the continuity of audio data playback, in the process of switching from the second application to the first application, it is necessary to ensure that the Bluetooth connection between the display device 200 and the first Bluetooth device is not disconnected, and the display device 200 is always in sink mode to receive the first audio data sent by the first Bluetooth device. Therefore, the display device 200 needs to lock the first Bluetooth switch in the on state and lock the Bluetooth mode in sink mode.

[0515] In some exemplary embodiments, when the display device 200 is in sink mode, if the display device 200 is connected to the first Bluetooth device and plays the first audio data 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 the art paintings at the same time, it can switch to the first application, such as by pressing the power button, the art mode button on the remote control, or selecting the icon of the art mode application in the sidebar / shortcut menu to enter the first application. After entering the first application, the display device 200 will display the display page of the first application and display the first picture (such as art paintings) in the display page. After the display device 200 recognizes that the application after switching is the first application, the first Bluetooth switch is locked in the on state and locked in sink mode. In this way, the display device 200 can always remain connected to the first Bluetooth device and receive the first audio data sent by the first Bluetooth device during the process of switching to the first application, that is, the continuous playback of the first audio data can be guaranteed when switching applications.

[0516] It should be noted that the process of switching from the second application to the first application is similar to the specific implementation process of switching from the first application to the second application mentioned above, and will not be repeated here.

[0517] The music playback method provided in the embodiment of the present application avoids interruption of the audio data played during the switching from the second application to the first application by locking the first Bluetooth switch in the on state and maintaining the sink mode during the switching from the second application to the first application, thereby ensuring the continuity of the audio data playback during the application switching process and improving the user experience; and there is no need for frequent operations during the application switching process to ensure continuous playback of the audio data during the application switching process.
