[0059] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention will be further described below with reference to the accompanying drawings and examples. However, the example embodiments can be implemented in various forms and should not be understood as being limited to the embodiments described herein; on the contrary, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concepts of the example embodiments to those skilled in the art. The same figure marks in the figures represent the same or similar structures, and their repeated descriptions will be omitted. The words expressing position and direction described in the present invention are all explained with reference to the accompanying drawings as examples, but changes can be made as needed, and the changes made are all included in the scope of protection of the present invention. The drawings of the present invention are only used to illustrate the relative position relationship and do not represent the true proportion.

[0060] With the advancement of science and technology, people can use Bluetooth devices to adjust display devices. However, after a display device and a Bluetooth device are connected, the connection may be disconnected due to external interference or other reasons. Currently, after the display device and Bluetooth device are disconnected, the Bluetooth device sends connection signals at a fixed frequency, and the display device scans for connection signals sent by the Bluetooth device at a fixed scanning period. This slows down the connection recovery process between the display device and the Bluetooth device, making it easily noticeable to the user.

[0061] For example, Figure 1 As shown, Figure 1 The following is an interactive flow chart of restoring the connection between a display device and a Bluetooth device after the connection is disconnected in the prior art. Figure 1As shown, the Bluetooth device sends a connection signal to the display device at a fixed frequency, and the display device scans the connection signal sent by the Bluetooth device at a fixed scanning period. When the display device scans the connection signal sent by the Bluetooth device, it establishes a connection with the Bluetooth device, that is, the display device and the Bluetooth device are restored to a connection state.

[0062] Based on this, embodiments of the present application provide a display device, connection method, and storage medium. The display device can determine a target connection mode from multiple preset connection modes, scan for connection signals sent by a Bluetooth device according to the scanning period included in the target connection mode, and then establish a connection with the Bluetooth device based on the connection signal sent by the Bluetooth device. This method allows the display device and Bluetooth device to quickly restore their connection after a disconnection, making it difficult for the user to detect.

[0063] Figure 2 This is a schematic diagram of the operation scenario of the embodiment of the present application, such as Figure 2 As shown, a user can operate the display device 200 via a Bluetooth device, where the Bluetooth device can be a mobile terminal 300 or a control device 100. The control device 100 can be a remote control, and communication between the remote control and the display device includes infrared protocol communication, Bluetooth protocol communication, wireless or other wired methods to control the display device 200. The user can control the display device 200 by inputting user commands through buttons on the remote control, voice input, control panel input, etc. In some embodiments, a mobile terminal, tablet computer, computer, laptop computer, and other smart devices can also be used to control the display device 200.

[0064] In some embodiments, the mobile terminal 300 can install software applications with the display device 200, and achieve connection and communication through a network communication protocol to achieve the purpose of one-to-one control operation and data communication. The audio and video content displayed on the mobile terminal 300 can also be transmitted to the display device 200 to achieve a synchronous display function. The display device 200 also communicates data with the server 400 through a variety of communication methods. The display device 200 can be allowed to communicate and connect through a local area network (LAN), a wireless local area network (WLAN) and other networks. The server 400 can provide various content and interactions to the display device 200. The display device 200 can be a liquid crystal display, an OLED display, or a projection display device. In addition to providing a broadcast receiving television function, the display device 200 can also provide an intelligent network TV function that provides computer support functions.

Figure 3As shown, the control device 100 includes a controller 110, a communication interface 130, a user input / output interface 140, a memory, and a power supply. The control device 100 can receive user input operation commands and convert the operation commands into commands that the display device 200 can recognize and respond to, acting as an intermediary for interaction between the user and the display device 200. The communication interface 130 is used for external communication and includes at least one of a Wi-Fi chip, a Bluetooth module, NFC, or an alternative module. The user input / output interface 140 includes at least one of a microphone, a touchpad, a sensor, a button, or an alternative module.

[0066] Figure 4 This is a hardware configuration block diagram of a display device 200 provided in an embodiment of the present application. Figure 4 The display device 200 shown includes at least one of a tuner and demodulator 210, a communicator 220, a detector 230, an external device interface 240, a processor 250, a display 260, an audio output interface 270, a memory, a power supply, and a user interface 280. The processor includes a central processing unit (CPU), a video processor, an audio processor, a graphics processor, RAM, ROM, and first to nth interfaces for input / output. The display 260 can be at least one of a liquid crystal display (LCD), an OLED display, a touch display, and a projection display, and can also be a projection device and a projection screen. The tuner and demodulator 210 receives broadcast television signals via wired or wireless reception, and demodulates audio and video signals, such as EPG data signals, from multiple wireless or wired broadcast television signals. The detector 230 is used to collect signals from the external environment or external interactions. The processor 250 and tuner and demodulator 210 can be located in different separate devices, that is, the tuner and demodulator 210 can also be located in a device external to the main device where the processor 250 is located, such as an external set-top box.

[0067] In some embodiments, the processor 250 controls the operation of the display device and responds to user operations through various software control programs stored in the memory. The processor 250 controls the overall operation of the display device 200. A user can enter user commands through a graphical user interface (GUI) displayed on the display 260, and the user input interface receives the user input commands through the graphical user interface (GUI). Alternatively, the user can enter user commands by inputting specific sounds or gestures, and the user input interface recognizes the sounds or gestures through sensors to receive the user input commands.

[0068] In some embodiments, a "user interface" is a medium interface for interaction and information exchange between an application or operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. A common form of user interface is a graphical user interface (GUI), which refers to a user interface related to computer operations that is displayed in a graphical manner. It can be an interface element such as an icon, window, or control displayed on the display screen of an electronic device, where a control can include at least one of a visual interface element such as an icon, button, menu, tab, text box, dialog box, status bar, navigation bar, or widget.

The Kernel layer includes at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, Wi-Fi driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver.

[0070] To further illustrate the technical solutions provided by the embodiments of the present application, this is described in detail below with reference to the accompanying drawings and specific implementation methods. Although the embodiments of the present application provide the method operation steps as shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative labor. In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided by the embodiments of the present application. The method may be executed or executed in parallel in the order of the methods shown in the embodiments or drawings during the actual processing process or when the device is executed.

[0071] According to actual application conditions, the embodiments of this application can be divided into three situations: the first is that the display device does not receive the key monitoring information sent by the Bluetooth device within the first set time; the second is that the display device receives the key monitoring information sent by the Bluetooth device within the first set time and scans the connection signal sent by the Bluetooth device according to the target connection mode; the third is that the display device receives the key monitoring information sent by the Bluetooth device within the first set time, but does not scan the connection signal sent by the Bluetooth device according to the target connection mode. For ease of understanding, the connection method provided by this application is described in detail below through three specific embodiments.

[0072] Example 1

[0073] Figure 6 FIG1 shows an interactive flow chart of a connection method provided by an embodiment of the present application in the first case. Figure 6 As shown, the method may include the following steps:

[0074] In step S601 , after the display device establishes a connection with the Bluetooth device, the status monitoring module is turned on.

[0075] Step S602: After the display device determines through the status monitoring module that the connection with the Bluetooth device is abnormally disconnected, the key monitoring module is activated.

[0076] Specifically, after the display device and the Bluetooth device establish a connection, the status monitoring module can be turned on. The display device can monitor the connection status between the display device and the Bluetooth device through the status monitoring module. If the display device detects that the display device and the Bluetooth device are disconnected through the status monitoring module, the key monitoring module can be turned on.

[0077] In the embodiment of the present application, abnormal disconnection refers to any other disconnection method other than manual disconnection by the user.

[0078] Step S603: The display device sends a key monitoring request to the Bluetooth device through the key monitoring module.

[0079] Step S604: If the display device does not receive the key monitoring information sent by the Bluetooth device within the first set time period, the first connection mode among the preset multiple connection modes is used as the target connection mode.

[0080] Step S605: The display device scans for connection signals sent by the Bluetooth device according to the scanning period included in the first connection mode.

[0081] In the embodiment of the present application, the scanning cycle may include a scanning duration and an interval duration, such as Figure 7As shown, 704 represents the first scanning cycle, 701 is the scanning time period of the first scanning cycle, and the duration corresponding to the scanning time period is the scanning duration. 702 is the interval time period of the first scanning cycle, and the duration corresponding to the interval time period is the interval duration. 703 is the scanning time period of the second scanning cycle. During the scanning time period, the display device can be in a scanning state, scanning for connection signals sent by Bluetooth devices; during the interval time period, the display device can be in a silent state, that is, it stops scanning for connection signals sent by Bluetooth devices.

[0082] In the embodiment of the present application, the display device can preset three connection modes, and the scanning duration and interval duration of the three connection modes are different. For example, Figure 8 、 Figure 9 and Figure 10 As shown, Figure 8 Schematic diagram of the scanning period of the first connection mode. The scanning duration of the first connection mode may be 40 milliseconds and the interval duration may be 10 seconds. Figure 9 Schematic diagram of the scanning period of the second connection mode. The scanning duration of the second connection mode may be 80 milliseconds and the interval duration may be 3 seconds. Figure 10 Figure 1 is a schematic diagram of the scanning period of the third connection mode. The scanning duration of the third connection mode can be 100 milliseconds, and the interval duration can be 1 second. The scanning duration of the second connection mode is longer than that of the first connection mode, the scanning duration of the third connection mode is longer than that of the second connection mode, and the interval duration of the second connection mode is shorter than that of the first connection mode; the interval duration of the third connection mode is shorter than that of the second connection mode.

[0083] In an embodiment of the present application, the connection modes preset in the display device may include more or fewer types, for example, 2 connection modes, or 4 connection modes, which is not limited in the present application.

[0084] Step S606: After the display device scans for a connection signal, it establishes a connection with the Bluetooth device.

[0085] The display device may establish a connection with the Bluetooth device after scanning for a connection signal sent by the Bluetooth device according to the scanning period included in the first connection mode.

[0086] Example 2

[0087] Figure 11 FIG2 shows an interactive flow chart of a connection method provided by an embodiment of the present application in the second case. Figure 11 As shown, the method may include the following steps:

[0088] Step S1101 : After establishing a connection with a Bluetooth device, the display device starts a status monitoring module.

[0089] Step S1102: After the display device determines through the status monitoring module that the connection with the Bluetooth device is abnormally disconnected, the key monitoring module is activated.

[0090] Step S1103: The display device sends a key monitoring request to the Bluetooth device through the key monitoring module.

[0091] Step S1104 : The Bluetooth device sends key monitoring information to the display device in response to the user's triggering operation on any key.

[0092] Specifically, after the display device turns on the key monitoring module, it can send a key monitoring request to the Bluetooth device through the key monitoring module. After receiving the key monitoring request sent by the display device, the Bluetooth device can respond to the user's triggering operation on any key and send key monitoring information to the Bluetooth device. The key monitoring information may include the key identifier of the key triggered by the user.

[0093] Step S1105 : The display device determines a target connection mode from a plurality of preset connection modes according to the key monitoring information.

[0094] Specifically, in some embodiments, when the display device determines the target connection mode from a plurality of preset connection modes according to the key monitoring information, it can refer to Figure 12 The method shown, such as Figure 12 As shown, the method includes:

[0095] Step S1201: Check whether the key identifier included in the key monitoring information is a second-category key identifier; if so, execute step S1202; if not, execute step S1203;

[0096] Step S1202: using the third connection mode as the target connection mode;

[0097] Step S1203: Use the second connection mode as the target connection mode.

[0098] Among them, the second type of button identifiers include identifiers corresponding to buttons that transmit signals via Bluetooth, such as voice buttons, heart rate check buttons, etc.

[0099] In other embodiments, when the display device determines the target connection mode from a plurality of preset connection modes according to the key monitoring information, it can refer to Figure 13 The method shown, such as Figure 13 As shown, the method includes:

[0100] Step S1301: Check whether the key identifier included in the key monitoring information is a first-class key identifier; if so, execute step S1302; if not, execute step S1303;

[0101] Step S1302: Using the second connection mode as the target connection mode;

[0102] Step S1303: Use the third connection mode as the target connection mode.

[0103] The first type of button identifiers include identifiers corresponding to buttons in the Bluetooth device other than the buttons corresponding to the second type of button identifiers, such as volume adjustment buttons.

[0104] Step S1106: The display device scans for connection signals sent by the Bluetooth device according to the scanning period included in the target connection mode.

[0105] For example, in one embodiment, assuming that the target connection mode is the second connection mode, the display device may scan for connection signals sent by the Bluetooth device according to a scanning period included in the second connection mode.

[0106] In another embodiment, assuming that the target connection mode is the third connection mode, the display device may scan for connection signals sent by the Bluetooth device according to a scanning period included in the third connection mode.

[0107] Step S1107: After the display device scans for a connection signal, it establishes a connection with the Bluetooth device.

[0108] Example 3

[0109] Figure 14 FIG. 1 shows an interactive flow chart of a connection method provided by an embodiment of the present application in the third case. Figure 14 As shown, the method may include the following steps:

[0110] Step S1401: After establishing a connection with a Bluetooth device, the display device starts a status monitoring module.

[0111] Step S1402: After the display device determines through the status monitoring module that the connection with the Bluetooth device is abnormally disconnected, the key monitoring module is activated.

[0112] Step S1403: The display device sends a key monitoring request to the Bluetooth device through the key monitoring module.

[0113] Step S1404: The Bluetooth device sends key monitoring information to the display device in response to the user's triggering operation on any key.

[0114] Step S1405: The display device determines a target connection mode from a plurality of preset connection modes according to the key monitoring information.

[0115] Step S1406: The display device scans for connection signals sent by the Bluetooth device according to the scanning period included in the target connection mode.

[0116] Step S1407: If the display device does not scan for a connection signal sent by the Bluetooth device within the set time period, the first connection mode is used as the target connection mode.

[0117] Specifically, in some embodiments, when the display device fails to scan a connection signal sent by a Bluetooth device within a set time period and uses the first connection mode as the target connection mode, reference may be made to Figure 15 The method shown, such as Figure 15 As shown, the method includes:

[0118] Step S1501: Determine whether the target connection mode is the second connection mode from among the preset multiple connection modes based on the key monitoring information; if so, execute step S1502; if not, execute step S1503;

[0119] Step S1502: If no connection signal sent by the Bluetooth device is scanned within the second set time period, the first connection mode is used as the target connection mode.

[0120] Specifically, assuming that the display device determines the target connection mode as the second connection mode from the preset multiple connection modes based on the key monitoring information, and scans the connection signal sent by the Bluetooth device according to the scanning period included in the second connection mode, but fails to scan the connection signal sent by the Bluetooth device within the second set time period, the display device can use the first connection mode as the target connection mode and scan the connection signal sent by the Bluetooth device according to the scanning period included in the first connection mode.

[0121] Step S1503: If no connection signal sent by the Bluetooth device is scanned within the third set time period, the first connection mode is used as the target connection mode.

[0122] Specifically, assuming that the display device determines that the target connection mode is the third connection mode from the preset multiple connection modes based on the key monitoring information, and scans the connection signal sent by the Bluetooth device according to the scanning period included in the third connection mode, but fails to scan the connection signal sent by the Bluetooth device within the third set time period, the display device can use the first connection mode as the target connection mode and scan the connection signal sent by the Bluetooth device according to the scanning period included in the first connection mode.

[0123] In an embodiment of the present application, the second set time length and the third set time length can be set according to actual conditions. For example, the second set time length can be 30 seconds and the third set time length can be 5 seconds. This application does not limit this.

[0124] Step S1408: The display device scans for connection signals sent by the Bluetooth device according to the scanning period included in the first connection mode.

[0125] Step S1409: After the display device scans the connection signal, it establishes a connection with the Bluetooth device.

[0126] Through the above method, after the display device and the Bluetooth device are disconnected, different connection methods can be selected according to different situations, so that the display device and the Bluetooth device can quickly restore the connection state without being easily noticed by the user.

[0127] Figure 16 A flow chart of a connection method provided by an embodiment of the present application is shown, which is applied to a display device, such as Figure 16 As shown, the method includes:

[0128] Step S1601, start the status monitoring module;

[0129] Step S1602: Determine whether the connection with the Bluetooth device is abnormally disconnected through the status monitoring module. If so, execute step S1603; if not, execute step S1601;

[0130] Step S1603, start the key monitoring module;

[0131] Step S1604: Send a key monitoring request to the Bluetooth device;

[0132] Step S1605: Whether the key monitoring information sent by the Bluetooth device is received within the first set time period; if so, execute step S1606; if not, execute step S1612;

[0133] Step S1606: Check whether the key identifier included in the key monitoring information is a first-class key identifier; if so, execute step S1607; if not, execute step S1610;

[0134] Step S1607: using the second connection mode as the target connection mode;

[0135] Step S1608: Whether a connection signal sent by a Bluetooth device is scanned within the second set time period; if so, executing step S1609; if not, executing step S1612;

[0136] Step S1609: After scanning the connection signal sent by the Bluetooth device, establish a connection with the Bluetooth device;

[0137] Step S1610: using the third connection mode as the target connection mode;

[0138] Step S1611: Whether a connection signal sent by a Bluetooth device is scanned within the third set time period; if so, execute step S1609; if not, execute step S1612;

[0139] Step S1612: Use the first connection mode as the target connection mode.
