With the continuous upgrade of the display device 200 and the expansion of the application of the bluetooth technology, the current display device 200 generally has bluetooth related functions. Bluetooth technology, as an open global specification for wireless data and voice communications, has recently emerged to many bluetooth standard devices, such as bluetooth speakers, bluetooth keyboards, bluetooth mice, bluetooth remote controllers, and the like.

The display device 200 may also function as a standard bluetooth device 500, capable of being scanned and connected by various other bluetooth devices 500. However, there are currently some bluetooth devices 500 that can actively initiate a connection to a bluetooth-enabled device such as the display device 200. When the bluetooth devices 500 initiate a connection request, an information prompt of the device 200 is displayed, which pops up the bluetooth pairing connection. Such information prompts may interfere with the normally played content of the display device 200 and may also affect the user experience if the bluetooth device 500 is already connected to the display device 200, or the content is currently playing, etc.

Taking the example where the display device 200 is a mobile phone and the bluetooth device 500 is a bluetooth headset, if the bluetooth headset m scans the mobile phone of the user, it will immediately and actively send a pairing request to the mobile phone. As shown in fig. 5, after receiving the pairing request, the mobile phone pops up a pairing prompt page on the current display content, and displays a prompt of "whether to pair with the bluetooth headset m" and controls such as "pair", "cancel", and the like on the pairing prompt page. If the mobile phone is connected with the user's own bluetooth headset and the user does not want to change the bluetooth headset m, the currently displayed pairing prompt page on the mobile phone affects the content currently being viewed by the user.

In order to solve the problem of interference of the unpaired bluetooth device 500 with the display device 200, the display device 200 in the embodiment of the present application may be provided with a bluetooth visibility switch, which may be turned off when the user does not want the display device 200 to connect to the bluetooth device 500; alternatively, the bluetooth visibility switch may be turned off when the display apparatus 200 has connected one bluetooth apparatus 500 and the user does not want the other bluetooth apparatus to connect the display apparatus 200. When the bluetooth visibility switch is turned off, the display device 200 will not be scanned by the bluetooth device 500, and the bluetooth device 500 will not actively send a pairing request to the display device 200. In this way, the display device 200 can be used normally or display contents without being interfered with by the pairing prompt of the bluetooth device 500.

The display device 200 of the embodiment of the application can display the bluetooth visibility switch on the bluetooth setting page, and when a user needs to control the bluetooth visibility switch, the user can firstly input a first page display instruction to the display device 200, and then control the display device 200 to display the bluetooth setting page. Then, in order to avoid the interference of the bluetooth device 500 to the display device 200, the user inputs a close instruction to the display device 200 on the bluetooth setup page, and controls the bluetooth visibility switch to close.

Referring to fig. 6, fig. 6 illustrates a schematic diagram of a bluetooth settings page according to some embodiments. On this bluetooth settings page, a bluetooth visibility switch may be displayed. The Bluetooth visibility switch is a switch control capable of moving left and right, and when the switch control moves right, the Bluetooth visibility switch is turned on; the switch control moves to the left, indicating that the bluetooth visibility switch is off.

Referring to fig. 7, fig. 7 illustrates a schematic diagram of turning off a bluetooth visibility switch on a display device 200 according to some embodiments. In the above-described process of turning off the bluetooth visibility switch, the controller 250 of the display apparatus 200 may be configured to: first, the display 260 is controlled to display a bluetooth setup page in response to a first page display instruction input by the user. Then, in response to a close instruction input by the user on the bluetooth setting page, the bluetooth visibility switch is controlled to be closed. Finally, when the bluetooth visibility switch is turned off, the display device 200 is controlled to be in a non-scannable state, thereby preventing the unpaired bluetooth device 500 from interfering with the display device 200.

In the foregoing embodiments, the user may input a control instruction to the display device 200 through a physical remote controller or a virtual remote controller, for example, pressing a direction key to control the focus movement on the page of the display device 200, pressing a confirmation key to select the option or content where the focus is located, and the like. The user may also input a control instruction to the display apparatus 200 by inputting voice content to the display apparatus 200 capable of providing a voice service, for example, inputting voice content "open bluetooth setup page" or the like.

In some embodiments, the bluetooth settings page does not exist separately, but rather belongs to a sub-page of the settings page. In this case, the user needs to first input a second page display instruction to the display apparatus 200, and control the display apparatus 200 to display the setting page. In this process, the controller 250 of the display apparatus 200 may be further configured to: first, the display 260 is controlled to display a setting page in response to a second page display instruction input by the user. Then, a first page display instruction for selecting the Bluetooth setting option is received, wherein the first page display instruction is input on the setting page by the user.

Referring to FIG. 8, FIG. 8 illustrates a schematic diagram of a settings page according to some embodiments. On this setting page, function options such as sound option, input option, parental control option, bluetooth option may be displayed. When the user selects the bluetooth option on the setup page, the display device 200 displays the bluetooth setup page.

If the user needs the display device 200 to connect to the bluetooth device 500 or needs the display device 200 to replace another bluetooth device 500 for connection, the user may turn on the bluetooth visibility switch. When the bluetooth visibility switch is turned on, the display device 200 may be scanned by the bluetooth device 500, and the bluetooth device 500 may actively send a pairing request to the display device 200. Thus, the user can control the display device 200 to connect with the target bluetooth device according to his or her own needs.

Referring to fig. 9, fig. 9 illustrates a schematic diagram of turning on a bluetooth visibility switch on a display device 200 according to some embodiments. In the above-described process of turning on the bluetooth visibility switch, the controller 250 of the display device 200 may be further configured to: first, the bluetooth visibility switch is controlled to be turned on in response to an on instruction input by a user on the bluetooth setup page. Then, when the bluetooth visibility switch is turned on, the display device 200 is controlled to be in a state in which it can be scanned, so that the display device 200 can be scanned by the bluetooth device 500.

After the bluetooth visibility switch is turned on, the bluetooth device 500 that can scan the display device 200 may be the bluetooth device 500 that has already been paired with the display device 200 or the bluetooth device 500 that has not been paired with the display device 200.

For the bluetooth device 500 that has been paired with the display device 200, the display device 200 has already saved the device information of the bluetooth device 500, and the bluetooth device 500 has also saved the device information of the display device 200. Therefore, after the bluetooth device 500 scans the display device 200, the connection request may be directly transmitted without transmitting the pairing request to the display device 200 again. The display apparatus 200 directly connects with the bluetooth apparatus 500 according to the connection request.

Referring to fig. 10, fig. 10 illustrates a schematic diagram of a connection between a display device 200 and a paired bluetooth device, according to some embodiments. In the above-described process of the display device 200 being connected with the paired bluetooth device, the controller 250 of the display device 200 may be configured to: first, when the bluetooth visibility switch is turned on, the display apparatus 200 is controlled to receive a connection request transmitted from a paired bluetooth apparatus. Then, the display device 200 is controlled to be connected with the paired bluetooth device according to the connection request.

For the unpaired bluetooth device 500, since the display device 200 does not store the device information of the bluetooth device 500, the device information of the display device 200 is not stored in the bluetooth device 500. Therefore, after the unpaired bluetooth device scans the display device 200, a pairing request needs to be sent to the display device 200. After the display device 200 agrees to pair with the unpaired bluetooth device, the unpaired bluetooth device can pair with the display device 200 to connect.

In some embodiments, after the unpaired bluetooth device sends the pairing request to the display device 200, the display device 200 does not actively pair with the unpaired bluetooth device, but displays a pairing prompt page to prompt the user whether the display device 200 needs to be paired with the unpaired bluetooth device.

Referring to FIG. 11, FIG. 11 illustrates a schematic diagram of a pairing hint page according to some embodiments. The pairing prompt page displays a Bluetooth pairing request and a connection with the mobile phone, and the user is ensured that a password is displayed on the mobile phone: 967919 ", etc., and also displays options such as" pair "and" cancel ". If the user determines that the pairing password displayed on the mobile phone to be paired is: 967919, the user can select the "pairing" option to input pairing instructions to the display device 200 to control the display device 200 to pair with the mobile phone.

Typically, the display device 200 can be connected to the unpaired bluetooth device immediately after the pairing with the unpaired bluetooth device is completed. At this point, the unpaired bluetooth device becomes the paired bluetooth device.

After the display device 200 displays the pairing prompt page, if the user finds that the pairing password displayed on the mobile phone is wrong or does not want to pair with the mobile phone, the user may select a "cancel" option, and further input a cancel instruction to the display device 200, and control the display device 200 to continue displaying normal content. At this time, the display device 200 still maintains the current bluetooth connection state and does not pair with the mobile phone.

Referring to fig. 12, fig. 12 illustrates a schematic diagram of a display device 200 connected with an unpaired bluetooth device, according to some embodiments. In the above-described process of the display device 200 being connected with the unpaired bluetooth device, the controller 250 of the display device 200 may be further configured to: first, when the bluetooth visibility switch is turned on, the display apparatus 200 is controlled to receive a pairing request transmitted from an unpaired bluetooth apparatus. Then, according to the pairing request, the display 260 is controlled to display a pairing prompt page, thereby prompting the user to pair the display device 200 with the unpaired bluetooth device.

The controller 250 may also be configured to: and in response to a pairing instruction input by the user on the prompt page, controlling the display device 200 to pair with the unpaired bluetooth device, wherein the unpaired bluetooth device becomes a paired bluetooth device after completing pairing. After the pairing is completed, the display device 200 continues to be controlled to connect with the paired bluetooth device.

In the foregoing embodiments, the method of the present application is described by taking an example in which an unpaired bluetooth device actively sends a pairing request to the display device 200. In some embodiments, the unpaired bluetooth device may also passively send a pairing request to the display device 200 according to a user's operation or the like. For example, some cell phones, after having bluetooth enabled, can scan many devices, including the display device 200. At this time, as shown in fig. 13, all the names of the scanned devices on the bluetooth device list of the mobile phone may be, where the name of the display device 200 may be "smart tv a 4". If the user wants the cell phone to connect to the display device 200, the user can click "smart tv a 4" on the bluetooth device list, at which point the cell phone sends a pairing request to the display device 200. After the display device 200 receives the pairing request, a pairing prompt page is displayed.

In order to avoid an excessively complicated operation of the paired bluetooth device each time it is connected to the display device 200, device information of the paired bluetooth device is generally stored in the display device 200. If the display device 200 is not currently connected with any bluetooth device 500 and is in a scannable state, the display device can be preferentially connected with the paired bluetooth device without being paired with the bluetooth device again.

For example, bluetooth device a, bluetooth device B, and bluetooth device C may all scan for display device 200, but only bluetooth device B has been paired with display device 200, then display device 200 will preferentially connect with bluetooth device B. If the user wants to replace the bluetooth device a, the display device 200 needs to be controlled to be paired with the bluetooth device a and directly connected with the bluetooth device a after the pairing.

When a plurality of paired bluetooth devices scan the display device 200, in order to avoid connection conflict of the paired bluetooth devices, the display device 200 determines the paired bluetooth device that has been connected last time and connects with the paired bluetooth device.

For example, the paired bluetooth device a, the paired bluetooth device b, and the paired bluetooth device c respectively scan the display device 200, and the display device 200 determines that the paired bluetooth device c is connected to the paired bluetooth device a most recently. The display device 200 preferentially connects with the paired bluetooth device c. If the user wants to replace the bluetooth device a, the paired bluetooth device a may be selected in the bluetooth device list provided by the display device 200.

Referring to fig. 14, fig. 14 shows a schematic diagram of a bluetooth device list of a display device 200 according to some embodiments. Taking the paired bluetooth device a, the paired bluetooth device b, and the paired bluetooth device c scanned to the display device 200 as an example, names of the paired bluetooth device a, the paired bluetooth device b, and the paired bluetooth device c may be displayed on the bluetooth device list of the display device 200. If the display device 200 is connecting with the paired bluetooth device c, a prompt of "connected" is displayed at the position of the bluetooth device c on the bluetooth device list, and prompts of "paired" are displayed at the positions of the bluetooth devices a and b. If the user wants to replace the paired bluetooth device a, the user can select the bluetooth device a from the bluetooth device list, and after connection, as shown in fig. 15, a prompt of "connected" is displayed at the location of the bluetooth device a, and a prompt of "paired" is displayed at the location of the bluetooth device c.

In some embodiments, to avoid multiple operations of the display device 200 bluetooth visibility switch by the user, the display device 200 may also save the bluetooth visibility state before each power off. Thus, when turned on again, the display device 200 can resume the bluetooth visible state before being turned off, so as to prevent the user from repeatedly setting and operating.

In the above process of restoring the bluetooth visibility state before the power-off of the display apparatus 200, the controller 250 of the display apparatus 200 may be further configured to: first, before the display apparatus 200 is powered off, if the bluetooth visibility switch is turned off, the turned-off state of the bluetooth visibility switch is saved. Then, the display apparatus 200 is controlled to be powered off. Finally, when the display apparatus 200 is powered on again, the current bluetooth visibility switch is set to the off state that has been saved before the power off.

Alternatively, the controller 250 may be further configured to: first, before the display apparatus 200 is powered off, if the bluetooth visibility switch is turned on, the on state of the bluetooth visibility switch is saved. Then, the display apparatus 200 is controlled to be powered off. Finally, when the display apparatus 200 is powered on again, the current bluetooth visibility switch is set to the on state that has been saved before the power off.

As can be seen, the display device 200 in the embodiment of the present application may first display the bluetooth setup page according to the operation of the user. If the display device 200 is currently connected to a certain bluetooth device, in order to avoid interference of other unpaired bluetooth devices 500 to the currently and normally used display device 200, the user may turn off the bluetooth visibility switch on the bluetooth setup page, after the bluetooth visibility switch is turned off, the currently connected bluetooth device 500 is not affected, and other unpaired bluetooth devices 500 cannot scan the display device 200 or send pairing requests to the display device 200, so that interference of the normally displayed content due to display of request information of the unpaired bluetooth device by the display device 200 may be avoided.
