FIG. 5 shows a schematic diagram of the display device 200 searching for surrounding Bluetooth devices 400 through Bluetooth. As shown in FIG. 5 , the Bluetooth devices 400 searched by the display device 200 include device A, device B, device C and device D. Among them, the distances between device A, device B, device C and device D and the display device 200 are 10cm, 15cm, 60cm and 70cm respectively. In this embodiment, the Bluetooth device 400 searched by the display device 200 may be called the first Bluetooth device, and the distance between the first Bluetooth device and the display device 200 may be called the communication distance, that is, device A, device B, and device C. and device D are both first Bluetooth devices, and the communication distances between these first Bluetooth devices and the display device 200 are 10cm, 15cm, 60cm, and 70cm respectively. The display device 200 will directly display the device information of one or more first Bluetooth devices for the user to select the target Bluetooth device to be connected.

As shown in FIG. 6 , the display device 200 displays a list of candidate Bluetooth devices. In this embodiment, the list of candidate Bluetooth devices includes device information of the candidate Bluetooth devices for the user to select for connection. Among them, if there is no Bluetooth device to be selected, the list of Bluetooth devices to be selected will be empty. The device information of the Bluetooth device to be selected may be the device name of the Bluetooth device to be selected, and the device name may be the name modified by the user or the number, model, etc. of the device itself. Based on the example given in FIG. 5 , the candidate Bluetooth device is one or more first Bluetooth devices searched by the display device 200 . Therefore, the device information of the one or more first Bluetooth devices is displayed on the candidate Bluetooth device. On the list, the list of Bluetooth devices to be selected corresponds to device A, device B, device C and device D in order from top to bottom. Among them, the device information of device A is the device model “*****7Pro 5G”, the device information of device B is the device number “2××××××××××9”, and the device information of device C is device The name (named by the user) is "Xiaohong's Tool", and the device information of device D is the device model "*****7Pro 5G". It can be seen that the device information of device A, device B and device D is relatively complicated and difficult to identify quickly. Moreover, the device information of device A and device D are the same. The user cannot distinguish the two devices based on the device information alone. Therefore, the user wants to connect For example, the Bluetooth device is device A. Obviously, the user cannot quickly and accurately determine the device information of device A based on the current device information. Although the device information of device C has a high degree of recognition, it can only be used by the user. Device C is excluded based on this device information, and the user still cannot determine device A from the device information of device A and device D. If the user tests whether he or she can connect to device A by trying to connect, once the user connects to device D first, and device D is an unfamiliar Bluetooth device, it will easily pose a threat to the user's privacy and security and the data security of the display device 200 .

In order to solve the above problems, this application provides a display device and a Bluetooth search method, which reduces the number of candidate Bluetooth devices displayed to the user by limiting the range of displayed candidate Bluetooth devices, thereby reducing the user's difficulty in judging the target Bluetooth device. range, improving the efficiency and accuracy of locating target Bluetooth devices. Refer to the process shown in Figure 7. The specific steps are as follows:

S701. Receive a first control instruction from a user regarding setting options of Bluetooth for the first user interface displayed on the display.

As shown in FIG. 1 , the user can send a first control instruction to the display device 200 through the control device 100 (such as a remote control) or through a smart device 300 (such as a mobile phone). Take the user controlling the display device 200 through the remote control as an example for explanation. The user controls the remote control to move the focus to the first Bluetooth setting option on the user interface, such as the first Bluetooth setting option hidden in the drop-down menu, the first Bluetooth setting option directly displayed on the system home page, or located in the settings menu. the first Bluetooth setting option, etc., and by pressing the "OK" option on the remote control to send the first control instruction to the display device 200 . Alternatively, the user sends an instruction to the display device 200 to display the settings menu by pressing a designated button on the remote control, such as the "Settings" button, and moves the focus to the first Bluetooth setting option in the setting menu by controlling the remote control, and The first control instruction is sent to the display device 200 by pressing the "OK" option on the remote control. In this embodiment, the first Bluetooth setting option refers to the entry option corresponding to the first search range setting menu, and the first control instruction is used to instruct the display device 200 to display the first search range setting menu.

S702. In response to the first control instruction, update the first user interface to obtain a second user interface, where the second user interface includes a first search range setting menu.

The display device 200 displays the first search range setting menu in response to the first control instruction. In this embodiment, the first search range setting menu provides multiple selectable distance values. As shown in Figure 8, the first search range setting menu includes distance values of 10cm, 50cm, 100cm, 300cm, 600cm, without limitation. The distance value may be called the first search range. In this embodiment, the first search range refers to the maximum distance between the first Bluetooth device that is finally displayed and the display device 200 , that is, the first Bluetooth device used to limit the display of device information. For example, the distance value 50cm means that the maximum distance between the first Bluetooth device that is finally displayed and the display device 200 is 50cm. That is, only the device information of the first Bluetooth device whose distance from the display device 200 is less than or equal to 50cm will be displayed. The device information of the first Bluetooth device that is displayed in the list of Bluetooth devices to be selected and whose distance from the display device 200 is greater than 50 cm will not be displayed.

In some embodiments, the first search range may be a fixed value, such as each distance data in Figure 8. These fixed first search ranges may be set based on big data, that is, these fixed first search ranges may satisfy The user's distance requirements for the first Bluetooth device shown. Users can directly select from these fixed first search ranges, making selection more efficient.

In some embodiments, the first search range may be an adjustable value, such as the first search range setting menu shown in Figure 9. The first search range setting menu includes a value input box 901, and the user can enter the value in the value input box 901. Enter the distance value you want to set, such as 10cm in Figure 9. Therefore, if the user knows the location of the first Bluetooth device near the display device 200 (ie, the distance between each first Bluetooth device and the display device 200), the user can determine the location of the first Bluetooth device based on the distance between the target Bluetooth device to be connected and other first Bluetooth devices. The first search range can be more accurately set based on the location difference between the devices, so as to more accurately limit the first Bluetooth device that displays the device information through the set first search range, and even accurately limit the first Bluetooth device that displays the device information. Restrict to target Bluetooth devices. For example, the distance between the target Bluetooth device and the display device 200 is 9 cm, and other first Bluetooth devices (which may be the remaining one or more first Bluetooth devices, or may be first Bluetooth devices within a certain range of the display device 200, The certain range is greater than the distance between the target Bluetooth device and the display device 200) and the distances from the display device 200 are 15cm, 20cm and 30cm respectively. Then the user can enter a distance value in the value input box 901. The distance value is located between the target Bluetooth device and the display device 200. A value between the distance to the display device 200 and the minimum distance between other first Bluetooth devices and the display device 200. In this example, the distance value input by the user is M, 9<M<15 (other first Bluetooth devices are minimum distance of the device 200), for example, M=10. Therefore, the displayed device information can be accurately limited to the target Bluetooth device through the first search range flexibly input by the user.

In some embodiments, as shown in FIG. 8 , the first search range setting menu includes an unrestricted option, which indicates that the first Bluetooth device displayed by the display device 200 is not restricted, that is, the display device 200 displays one or more first Bluetooth devices. Device information of a Bluetooth device to meet the user's need for a more comprehensive understanding of the first Bluetooth device nearby. For example, the user needs to know one or more first Bluetooth devices around to see whether there are suspicious Bluetooth devices in these first Bluetooth devices. equipment.

S703. Receive the first setting instruction sent by the user, where the first setting instruction indicates the target first search range.

The user selects the first search range to be set, that is, the target first search range, based on the first search range setting menu, and sends a first setting instruction to the display device 200 to instruct the display device 200 to set the target first search range.

In some embodiments, the user makes a selection based on the first search range setting menu as shown in FIG. 8 , that is, selects the target first search range from the fixed first search range. For example, the user controls the remote control to move the focus to the option of the target first search range, and presses the "confirm" button on the remote control to send a first setting instruction to the display device 200 to select the target first search range. Range, as shown in Figure 8, the first search range of the target selected by the user is 50cm. After sending the first setting command, the first search range of the target is marked with a mark indicating that it has been selected. As shown in Figure 8, the hollow circle on the left side of 50cm is changed to a solid circle to indicate that 50cm is the first search range of the target. In some embodiments, the target first search range may also have other marks to distinguish it from other first search ranges.

In some embodiments, the user makes a selection based on the first search range setting menu as shown in FIG. 9 , that is, manually inputs the target first search range in the numerical input box 901 . For example, the user moves the focus to the numerical input box 901 by controlling the remote control, and presses the "confirm" button on the remote control to adjust the numerical input box 901 to a state where text can be input. The user continues to control the remote control to input the target first search range in the numerical input box 901. As shown in Figure 9, the target first search range is 10 cm.

In some embodiments, the display device 200 stores the target first search range set each time, and directly uses the most recently saved target first search range when searching for a Bluetooth device next time.

In some embodiments, the user can reset the target first search range before each search for a Bluetooth device, so that the set target first search range is more consistent with the requirements for displaying device information at that time.

S704. In response to the first setting instruction, after searching for one or more first Bluetooth devices, only display that the distance between the one or more first Bluetooth devices and the display device is less than or equal to the target. Candidate Bluetooth devices in the first search range.

In response to the first setting instruction, the display device 200 sets the first search range as the target first search range, and when the display device 200 subsequently searches for a Bluetooth device, it displays the first Bluetooth device that meets the distance requirement based on the target first search range. device, that is, the Bluetooth device to be selected. It can be seen that in this embodiment, the Bluetooth devices to be selected are some Bluetooth devices that meet the distance requirements and are selected from one or more first Bluetooth devices, which can effectively reduce the amount of device information displayed in the list of Bluetooth devices to be selected. , so that users can determine the target Bluetooth device from a smaller amount of device information to improve the efficiency of finding the target Bluetooth device.

The process of displaying the list of Bluetooth devices to be selected by the display device 200 can refer to the process shown in Figure 10. The specific steps are as follows:

S1001. Receive a search instruction for a Bluetooth device sent by the user.

The user can send a search instruction to the display device 200 by controlling the remote control to instruct the display device 200 to search for nearby Bluetooth devices. For example, the user controls the remote control to adjust the Bluetooth function switch of the display device 200 to the on state to instruct the display device 200 to turn on the Bluetooth function. The user selects the Bluetooth search option of the display device 200 by controlling the remote control to send a search instruction to the display device 200 .

S1002. In response to the search instruction, search for Bluetooth devices and receive Bluetooth signals sent by one or more first Bluetooth devices.

In response to the search instruction, the display device 200 sends a Bluetooth signal, such as a broadcast request frame, to the surroundings to search for nearby Bluetooth devices. After receiving the request frame sent by the display device 200, the surrounding Bluetooth devices, if the Bluetooth device is available, feed back Bluetooth signals, such as response frames, to the display device 200, so that the display device 200 can discover itself. In this embodiment, the Bluetooth device that feeds back the response frame based on the request frame sent by the display device 200 is called the first Bluetooth device. For example, in the example shown in Figure 5, the Bluetooth devices that feed back one or more response frames include device A, device B, device C, and device D, then the above four Bluetooth devices are all first Bluetooth devices.

S1003. Obtain the signal strength of the Bluetooth signal sent by at least one first Bluetooth device among the one or more first Bluetooth devices.

After receiving the Bluetooth signal sent by the first Bluetooth device, the display device 200 may determine the signal strength of the Bluetooth signal through analysis. The display device 200 can use the received signal strength indication (RSSI) to characterize the signal strength of the Bluetooth signal. The RSSI values are all negative values. The greater the absolute value of the RSSI value, the Bluetooth signal received by the display device 200 Correspondingly, under the same conditions, the weaker the signal strength is, the farther the distance between the first Bluetooth device and the display device 200 is.

S1004. Determine the communication distance corresponding to the signal strength of the Bluetooth signal sent by the at least one first Bluetooth device.

Based on the signal strength of the received Bluetooth signal, the display device 200 can calculate the communication distance corresponding to the signal strength, that is, the distance between the first Bluetooth device that sends the Bluetooth signal and the display device 200 .

In some embodiments, the display device 200 can calculate the communication distance corresponding to each first Bluetooth device based on the following fitting algorithm formula between signal strength and communication distance:

d＝10^((abs(RSSI)-A)/(10*n)) Formula (1)

Among them, d represents the communication distance, RSSI represents the signal strength, A represents the signal strength when the distance between the first Bluetooth device and the display device 200 is 1 meter, and n represents the environmental attenuation factor.

Based on the above formula, the display device 200 can accurately calculate the communication distance between each first Bluetooth device and the display device 200 . For example, the communication distance of device A is 10cm, the communication distance of device B is 15cm, the communication distance of device C is 60cm, and the communication distance of device D is 70cm.

In some embodiments, a large number of training samples can be used to obtain the correspondence between signal strength and communication distance through the training model, and further filter out the signal strength corresponding to each first search range from these correspondences, as shown in Figure 11 The corresponding list of the first search range and signal strength shown below. The display device 200 pre-stores the correspondence list to directly determine the signal strength corresponding to each first search range based on the correspondence list, where the signal strength in the correspondence list indicates that within the corresponding first search range, the desired Displays the minimum signal strength of the Bluetooth signal sent by the first Bluetooth device. For example, the first search range of 10cm corresponds to a signal strength of -50dBm. Within the first search range, only when the signal strength of the sent Bluetooth signal is greater than or equal to -50dBm, the device information of the first Bluetooth device will be displayed. in the list of Bluetooth devices to be selected.

S1005. Determine a candidate Bluetooth device from the one or more first Bluetooth devices, and the communication distance of the candidate Bluetooth device is less than or equal to the target first search range.

The description is given as an example where the target first search range is 50 cm and the one or more first Bluetooth devices are device A, device B, device C and device D.

In some embodiments, the candidate Bluetooth device is determined based on the communication distance of each first Bluetooth device calculated in S1004. The Bluetooth device to be selected is the first Bluetooth device whose communication distance is less than or equal to the target first search range, that is, device A and device B.

In some embodiments, the candidate Bluetooth device is determined based on the correspondence list between communication distance and signal strength prestored by the display device 200 in S1004. The signal strength of the Bluetooth signal sent by the Bluetooth device to be selected is greater than or equal to the signal strength corresponding to the target first search range. Based on the correspondence list, the display device 200 can determine that the signal strength corresponding to the target first search range of 50cm is -53dBm. If the signal strength of the Bluetooth signal sent by device A is obtained to be -10dBm, the signal strength of the Bluetooth signal sent by device B is The strength is -20dBm, the signal strength of the Bluetooth signal sent by device C is -60dBm, and the signal strength of the Bluetooth signal sent by device D is -70dBm, then the Bluetooth devices to be selected are device A and device B.

S1006. Display a list of candidate Bluetooth devices, which only includes the candidate Bluetooth devices, so that the user can select the target Bluetooth device to be connected from the candidate Bluetooth devices.

A list of candidate Bluetooth devices is generated and displayed based on the candidate Bluetooth devices determined in S1005. As shown in Figure 12, the candidate Bluetooth device list only includes device information corresponding to device A and device B. It can be seen that the number of candidate Bluetooth devices (2) determined based on the target first search range is significantly smaller than the number of one or more first Bluetooth devices (4), and the user can determine the target from a smaller number of device information. Bluetooth devices, thereby effectively reducing the energy expended by the user and improving the efficiency of determining the target Bluetooth device. Compared with the list of candidate Bluetooth devices shown in Figure 6, the list of candidate Bluetooth devices shown in Figure 12 not only reduces the amount of device information, but also device D that has the same device information as device A is no longer displayed in the list of candidate Bluetooth devices. Select the Bluetooth device list, thereby effectively preventing the device information of device D from interfering with the device information of device A, and preventing the user from mistakenly connecting device D, thereby effectively improving the accuracy of the user in determining the target Bluetooth device.

In order to facilitate the user to determine the target Bluetooth device from the Bluetooth devices to be selected, the display device 200 can optimize the display method of the list of Bluetooth devices to be selected, so as to display each Bluetooth device to be selected according to different sorting rules.

In some embodiments, the list of Bluetooth devices to be selected is displayed with reference to the process shown in Figure 13. The specific steps are as follows:

S1301. Identify the device type of the Bluetooth device to be selected.

The response frame sent by each first Bluetooth device will carry a field representing the device type. The display device 200 identifies the device type of each candidate Bluetooth device through the field representing the device type in the response frame of each candidate Bluetooth device.

Taking the Bluetooth devices to be selected as device A and device B as an example, the display device 200 can recognize that the device type of device A is a mobile phone (Mobile Phone) by identifying the fields representing the device types in the response frames sent by device A and device B. The device type of device B is television (TV).

S1302. Classify and display each of the candidate Bluetooth devices in the list of candidate Bluetooth devices according to the device type.

The display device 200 classifies the Bluetooth devices to be selected according to device types, displays each Bluetooth device to be selected in the list of Bluetooth devices to be selected according to the classification results, and indicates the device type corresponding to each type of Bluetooth device to be selected. As shown in Figure 14, device A and device B belong to two device types respectively. The device information of device A is displayed in the section indicated by the device type Mobile Phone, and the device information of device B is displayed in the section indicated by the device type TV. Device Information.

The user can quickly determine the device type corresponding to each Bluetooth device to be selected. Therefore, the user can quickly determine the target Bluetooth device based on the device type. Taking device A as the target Bluetooth device as an example, if the user does not know the device information of device A, that is, the user does not know that device A corresponds to "*****7Pro 5G", it is difficult to base the operation on device A and device B only. The device information tells which one corresponds to device A. However, the user can easily determine the device type of device A, that is, mobile phone. At this time, the user only needs to determine device A in the device information located in the section indicated by the device type Mobile Phone, as shown in Figure 14 , the section indicated by the device type being Mobile Phone includes the device information "*****7Pro 5G", you can quickly determine that the device information corresponds to the target Bluetooth device, that is, device A.

In some embodiments, each candidate Bluetooth device is further filtered based on the device type, and the filtered candidate Bluetooth devices still include multiple candidates. At this time, the user can determine among a small number of candidate Bluetooth devices based on specific device information. Target Bluetooth device, thereby effectively improving the efficiency of determining the target Bluetooth device.

In some embodiments, each candidate Bluetooth device can be displayed based on the historical number of times each candidate Bluetooth device has been selected. The list of candidate Bluetooth devices can be displayed with reference to the process shown in Figure 15. The specific steps are as follows:

S1501. Obtain the historical number of selections for each of the Bluetooth devices to be selected. The historical number of selections refers to the number of times the Bluetooth device to be selected is displayed when the display device searches for Bluetooth devices based on the target first search range. The total number of times in the list of Bluetooth devices to be selected.

The display device 200 stores the list information of each candidate Bluetooth device list. The list information includes the target first search range corresponding to the displayed candidate Bluetooth device list, and each candidate Bluetooth device in the candidate Bluetooth device list. device information. The display device 200 counts the historical number of times each first Bluetooth device can be selected based on the same target first search range within a specified storage number of times or within a specified time period, where the historical number of times it can be selected refers to the number of times it is displayed in the list of candidate Bluetooth devices. the total number of hits.

In one implementation, the display device 200 counts the specified storage times, for example, within 100 times, based on the target first search range of 50 cm, the historical selection times of each first Bluetooth device. By way of example, the first Bluetooth device includes device A and device B. Among them, the historical number of times that device A has been selected is 2 times, and the historical number of times that device B has been selected is 100 times.

In one implementation, the display device 200 counts the historical selection times of each first Bluetooth device based on the target first search range of 50 cm within a specified time period, such as within 7 days. By way of example, the first Bluetooth device includes device A and device B. Among them, the historical number of times that device A has been selected is 0, and the historical number of times that device B has been selected is 7 times.

It can be seen that each storage process of the display device 200 includes device B, that is, device B is always located within a distance of 50cm from the display device 200. It can be considered that device B is a location relative to the display device 200. Fixed bluetooth device. However, device A only appears twice within a range of 50 cm from the display device 200. It can be considered that device A is a Bluetooth device with a relatively flexible position relative to the display device 200.

S1502. Display each of the candidate Bluetooth devices in the list of candidate Bluetooth devices in order from low to high historical candidate times.

As shown in the schematic diagram of the living room furnishings in Figure 16, the display device 200 is located in the living room. The user holds the mobile phone and moves in the living room, that is, between the first position 1601 and the second position 1602. The first position 1601 and the display device 200 The distance between them is 80cm, the distance between the second position 1602 and the display device 200 is 10cm, the Bluetooth speaker is fixedly placed in the upper right corner of the living room, that is, the third position 1603, and the distance between the third position 1603 and the display device 200 The distance is 15cm.

For some first Bluetooth devices with relatively flexible positions, such as mobile phones, tablets, smart watches and other mobile devices, the position of these first Bluetooth devices relative to the display device 200 is not fixed, that is, they are usually not within the fixed first search range. Take the mobile phone shown in Figure 16 as an example. The mobile phone usually follows the user in different ranges from the display device 200. Taking the target first search range as 50cm as an example, when the user holds the mobile phone and is at the first position 1601, the mobile phone is not in the first position 1601. The mobile phone within the first search range of the target will not be displayed in the list of Bluetooth devices to be selected. When the user holds the mobile phone at the second position 1602, the mobile phone will be displayed in the list of Bluetooth devices to be selected if it is within the first search range of the target. . Therefore, the mobile phone is often not within the target first search range of the display device 200. Each time the display device 200 displays the first Bluetooth device based on the target first search range, the mobile phone will not be displayed every time. In the Bluetooth device list, that is, the number of times the mobile phone is displayed in the list of candidate Bluetooth devices (the number of historical candidate times of the mobile phone) will be less than the total number of times the display device 200 displays the list of candidate Bluetooth devices based on the target first search range.

Some first Bluetooth devices that have a relatively fixed relative position to the display device 200 , for example, some fixed furnishings around the display device 200 , such as Bluetooth speakers, Bluetooth doorbells, Bluetooth monitoring devices, etc., due to the relative position between these Bluetooth devices and the display device 200 The position is fixed. Taking the Bluetooth speaker shown in Figure 16 as an example, based on the same target first search range, such as 50cm, the Bluetooth speaker will be displayed in the list of Bluetooth devices to be selected every time, that is, these first Bluetooth devices are displayed in the list of Bluetooth devices to be selected. The number of times of the list (the number of historical candidates) will be equal to the total number of times the display device 200 displays the list of candidate Bluetooth devices based on the target first search range.

Based on the above two first Bluetooth devices, it is obvious that the first Bluetooth device with a relatively flexible location has a smaller number of historical selections within a specified storage number or within a specified time period than the first Bluetooth device with a fixed location.

Based on this, each candidate Bluetooth device is arranged in order from low to high in the order of historical candidate times, as shown in Figure 17, in which a downward arrow indicates that the historical candidate times of the candidate Bluetooth devices below are gradually increasing. Based on the list of candidate Bluetooth devices shown in Figure 17, the user can quickly and accurately determine that device A has fewer historical candidates than device B. The user may not be able to accurately obtain the device information of device A and device B, but the user can easily determine whether the position of the target Bluetooth device is flexible or fixed, and thereby determine the target based on the relative position attributes of the target Bluetooth device. Bluetooth device.

In one implementation, if the relative position of the target Bluetooth device that the user wants to connect to is flexible, such as the mobile phone shown in Figure 16, the user can determine the target Bluetooth device from top to bottom according to the list of Bluetooth devices to be selected. For example, determine device A as the target Bluetooth device.

In one implementation, if the relative position of the target Bluetooth device that the user wants to connect is fixed, such as the Bluetooth speaker shown in Figure 16, the user can determine the target Bluetooth device from bottom to top according to the list of Bluetooth devices to be selected. For example, determine device B as the target Bluetooth device.

In some embodiments, each Bluetooth device to be selected can be arranged in order from high to low in the historical number of times it has been selected. Correspondingly, the opposite process to the above process is used, based on the relative position attribute of the target Bluetooth device, from the Bluetooth device to be selected. Determine the target Bluetooth device in the list, which will not be described here.

In some embodiments, each candidate Bluetooth device can be displayed based on changes in the communication distance of each candidate Bluetooth device. Refer to the process shown in Figure 18 to display the list of candidate Bluetooth devices. The specific steps are as follows:

S1801. Obtain the communication distance of each candidate Bluetooth device in the previous search.

The display device 200 stores the list information of each candidate Bluetooth device list. The list information includes the target first search range corresponding to the displayed candidate Bluetooth device list, and each candidate Bluetooth device in the candidate Bluetooth device list. The device information of the list also includes the communication distance corresponding to each Bluetooth device to be selected.

For example, the target first search range corresponding to the last search is 50cm, and the candidate Bluetooth devices in the candidate Bluetooth device list include device A and device B. Among them, the communication distance of device A is 20cm, and the communication distance of device B is 15cm. It should be noted that in this embodiment, the last search and this search are both based on the same target first search range search.

S1802. In the list of candidate Bluetooth devices, display the candidate Bluetooth devices with different communication distances in this search and the communication distance in the previous search. In each search, the display device searches based on the target first search range.

This search of the display device 200 is also a search process based on the target first search range of 50cm. For example, the candidate Bluetooth devices in the candidate Bluetooth device list include device A and device B, where the corresponding communication distance of device A is 10cm. , the communication distance corresponding to device B is 15cm. Compared with the last search process, the communication distance of device A has changed, while the communication distance of device B has not changed. It can be seen from the communication distance that represents the distance between the first Bluetooth device and the display device 200 that relative movement occurs between device A and the display device 200, but no relative movement occurs between device B and the display device 200. Therefore, device A is a first Bluetooth device whose relative position is flexibly variable, and device B is a first Bluetooth device whose relative position is fixed.

The candidate Bluetooth devices whose communication distance has changed are displayed in partitions in the list of candidate Bluetooth devices, as well as the candidate Bluetooth devices whose communication distance has not changed. For example, the candidate Bluetooth devices whose communication distance changes are displayed first. In some embodiments, the above two types of candidate Bluetooth devices can be distinguished by identification. For example, as shown in Figure 19, the device information of the candidate Bluetooth devices whose communication distance has changed is displayed in bold, that is, the device information corresponding to device A is displayed in bold. Device information is displayed in bold.

In some embodiments, if the relative position of the target Bluetooth device that the user wants to connect to is flexibly variable, the target Bluetooth device can be determined from the candidate Bluetooth devices whose communication distance changes, such as device A in Figure 19.

In one implementation, if the relative position of the target Bluetooth device that the user wants to connect to is fixed, the target Bluetooth device can be determined from the candidate Bluetooth devices whose communication distance changes, such as device B in Figure 19.

In some embodiments, as shown in FIG. 20 , the communication distance of each Bluetooth device to be selected may also be marked in the list of Bluetooth devices to be selected. The user can roughly determine the communication distance between the target Bluetooth device and the display device 200 and combine it with the communication distance marked in the list of candidate Bluetooth devices to determine the target Bluetooth device whose communication distance matches. For example, if the user determines that the communication distance between the target Bluetooth device and the display device 200 is 10 cm, then based on the list of candidate Bluetooth devices as shown in FIG. 20 , device A with a marked communication distance of 10 cm can be quickly determined as the target Bluetooth device.

When displaying the list of candidate Bluetooth devices, each candidate Bluetooth device may also be displayed in combination with one or a combination of several of the above embodiments. For example, taking the first target search range of 60cm as an example, as shown in Figure 21, each candidate Bluetooth device is displayed according to device type classification. For example, Mobile Phone includes device information "*****7Pro 5G" (device a) , "*****8Pro 5G" (device b), "*****7 4G" (device c), TV includes device information "2×××××××××9" (device d ), "Xiaohong's Tool" (device e), and mark the communication distance of each Bluetooth device to be selected. For example, device a corresponds to 10cm, device b corresponds to 50cm, device c corresponds to 55cm, device d corresponds to 30cm, and device e corresponds to 40cm. . Display the selected Bluetooth devices corresponding to each device type according to the changes in communication distance. For example, Mobile Phone displays "*****7Pro 5G" first (and is shown in bold), "**** *8Pro 5G” and “*****7 4G” are shown below. There are no Bluetooth devices to be selected in the TV whose communication distance has changed. Therefore, “2××××××××××9” and “Xiaohong’s Tool” can be displayed in random order. Users can directly determine the target Bluetooth device based on understanding of the device information. Target Bluetooth devices can also be determined based on device type. The target Bluetooth device may also be determined based on the device type and the relative position attribute of the target Bluetooth device. The process of determining the target Bluetooth device may refer to the process disclosed above, which will not be described again here.

Figure 22 shows a schematic diagram of the display device 200 receiving a Bluetooth connection request sent by a surrounding Bluetooth device 400. In this embodiment, the sending device of the Bluetooth connection request received by the display device 200 can be called a second Bluetooth device. The distance between the second Bluetooth device and the display device 200 can be called the communication distance. The Bluetooth device 400 shown in Figure 22 can be called the second Bluetooth device. The distance between the Bluetooth device 400 and the display device 200 is 20cm, which can be called the second Bluetooth device. is the communication distance. As shown in ① in Figure 22, after receiving the Bluetooth connection request sent by the second Bluetooth device when playing video 1, the display device 200 will display the Bluetooth connection request on the current user interface, as shown in ② in Figure 22 , the Bluetooth connection request usually includes: request description text, such as "Bluetooth pairing request", device information of the second Bluetooth device (you can refer to the device information of the first Bluetooth device above, which will not be repeated here), For example, "From: *****7Pro 5G", ask for text, such as "Pair with this device?". The user interface also displays functional options, such as a Pair option 2201 for the user to send an instruction to the display device 200 to connect to the second Bluetooth device based on the Pair option 2201, and a Cancel option 2202 for the user to Based on the cancel option 2202, an instruction to reject the Bluetooth connection with the second Bluetooth device is sent to the display device 200. It can be seen that when the display device 200 displays the Bluetooth connection request sent by the second Bluetooth device, it will affect the normal display of the current user interface. If the second Bluetooth device is not a Bluetooth device controlled by the user to send a Bluetooth connection request, for example, another person's Bluetooth headset, a neighbor's Bluetooth device, etc., it will hinder the user's normal use of the display device 200 .

In order to solve the above problems, this application provides a method for processing display devices and Bluetooth connection requests. By limiting the range of Bluetooth devices corresponding to the received Bluetooth connection requests, the Bluetooth connection requests displayed to the user are filtered, thereby reducing the number of displayed Bluetooth connection requests. The number of Bluetooth connection requests that hinder the normal operation of the display device 200. Refer to the process shown in Figure 23. The specific steps are as follows:

S2301. Receive a second control instruction sent by the user for setting options related to Bluetooth in the first user interface displayed on the display device.

As shown in FIG. 1 , the user can send a second control instruction to the display device 200 through the control device 100 (such as a remote control) or through a smart device 300 (such as a mobile phone). Take the user controlling the display device 200 through the remote control as an example for explanation. The user controls the remote control to move the focus to the second Bluetooth setting option on the user interface, such as the second Bluetooth setting option hidden in the drop-down menu, the second Bluetooth setting option directly displayed on the system home page, or located in the settings menu. the second Bluetooth setting option, etc., and by pressing the "OK" option on the remote control to send a second control instruction to the display device 200 . Alternatively, the user sends an instruction to the display device 200 to display the settings menu by pressing a designated button on the remote control, such as the "Settings" button, and moves the focus to the second Bluetooth setting option in the setting menu by manipulating the remote control, and The second control instruction is sent to the display device 200 by pressing the "OK" option on the remote control. In this embodiment, the second Bluetooth setting option refers to the entry option corresponding to the second search range setting menu, and the second control instruction is used to instruct the display device 200 to display the second search range setting menu.

S2302. In response to the second control instruction, update the first user interface to obtain a second user interface, where the second user interface includes a second search range setting menu.

In response to the second control instruction, the display device 200 updates the user interface of the display device and displays the second search range setting menu on the updated graphical user interface. In this embodiment, the second search range setting menu provides multiple selectable distance values, as shown in Figure 24. The second search range setting menu includes distance values of 10cm, 50cm, 100cm, 300cm, 600cm, without limitation. The distance value may be called the second search range. In this embodiment, the second search range refers to the maximum distance between the second Bluetooth device displaying the Bluetooth connection request and the display device 200 , that is, used to limit the second Bluetooth device displaying the Bluetooth connection request. For example, the distance value 50cm means that the maximum distance between the second Bluetooth device displaying the Bluetooth connection request and the display device 200 is 50cm, that is, only the Bluetooth sent by the second Bluetooth device whose distance from the display device 200 is less than or equal to 50cm Only the connection request will be displayed, and the Bluetooth connection request of the second Bluetooth device whose distance from the display device 200 is greater than 50 cm will not be displayed.

In some embodiments, the second search range may be a fixed value, such as each distance data in Figure 24. These fixed second search ranges may be set based on big data, that is, these fixed second search ranges may satisfy The user's distance requirement for the second Bluetooth device for which the Bluetooth connection information is displayed. Users can directly select from these fixed second search ranges, making selection more efficient.

In some embodiments, the second search range may be an adjustable value, such as the second search range setting menu shown in Figure 25. The second search range setting menu includes a value input box 2501, and the user can enter the value in the value input box 2501. Enter the distance value you want to set, such as 10cm in Figure 25. Therefore, if the user knows the locations of the second Bluetooth devices that are allowed to display Bluetooth connection requests near the display device 200, the user can more accurately set the second search range based on the distance between these second Bluetooth devices and the display device 200. The set second search range more accurately limits the second Bluetooth devices that are allowed to display the Bluetooth connection request, and excludes other second Bluetooth devices.

S2303. Receive a second setting instruction for the search range of the second Bluetooth device sent by the user, where the second setting instruction indicates the target second search range.

The user selects the second search range to be set, that is, the target second search range, based on the second search range setting menu, and sends a second setting instruction to the display device 200 to instruct the display device 200 to set the target second search range.

In some embodiments, the user makes a selection based on the second search range setting menu as shown in FIG. 24 , that is, selects the target second search range from the fixed second search range. The setting process may refer to the above process of the user setting the target first search range based on the first search range setting menu shown in FIG. 8 , which will not be described again here.

In some embodiments, the user makes a selection based on the second search range setting menu as shown in Figure 25, that is, manually inputs the target second search range in the numerical input box 2501. The setting process may refer to the above process in which the user sets the target first search range based on the first search range setting menu shown in FIG. 9 , which will not be described again here.

In some embodiments, the display device 200 stores the target second search range set each time, and directly uses the most recently saved target second search range the next time the function of being discovered by other Bluetooth devices is turned on.

In some embodiments, the user can reset the target second search range each time before turning on the function of being discovered by other Bluetooth devices, so that the set target second search range is more consistent with the current Bluetooth connection request. Require.

S2304. In response to the second setting instruction, after receiving the Bluetooth connection request from the second Bluetooth device, the distance between the second Bluetooth device and the display device is less than or equal to the target second search range. At this time, the Bluetooth connection request of the second Bluetooth device is displayed on the updated user interface.

In response to the second setting instruction, the display device 200 sets the second search range as the target second search range, and when the display device 200 subsequently receives a Bluetooth connection request, displays the second search range that meets the distance requirement based on the target second search range. Bluetooth connection request from the second Bluetooth device. It can be seen that in this embodiment, the displayed Bluetooth connection requests are selected from one or more received Bluetooth connection requests and correspond to the partial Bluetooth connection requests of the second Bluetooth device that meet the distance requirements, which can effectively reduce the number of displayed Bluetooth connections. the number of impressions requested, thereby reducing the impact on the user's normal use of the display device 200.

The process of the display device 200 displaying the Bluetooth connection request can refer to the process shown in Figure 26. The specific steps are as follows:

S2601. Receive a Bluetooth connection request sent by the second Bluetooth device.

The user can send a start instruction to the display device 200 by controlling the remote control to instruct the display device 200 to turn on the Bluetooth function to receive a Bluetooth connection request sent by a nearby Bluetooth device.

S2602. Obtain the signal strength corresponding to the Bluetooth connection request.

The Bluetooth connection request sent by the second Bluetooth device is a Bluetooth signal. After receiving the Bluetooth signal, the display device 200 can determine the signal strength of the Bluetooth signal through analysis. The process of analyzing the signal strength can refer to the display device 200 analyzing the signal strength of the Bluetooth signal sent by the first Bluetooth device in S1003 above, which will not be described again here.

S2603. Determine the communication distance corresponding to the signal strength. The communication distance refers to the distance between the second Bluetooth device and the display device.

The process of determining the communication distance based on the signal strength may refer to S1004 to determine the communication distance between the first Bluetooth device and the display device 200 based on the signal strength of the Bluetooth signal sent by the first Bluetooth device, and to generate the corresponding relationship between the signal strength and the communication distance. The process of further selecting the signal strengths corresponding to each first search range from the corresponding relationship will not be described again here.

S2604. Determine whether the communication distance is less than or equal to the target second search range.

S2605. If the communication distance is less than or equal to the target second search range, display the Bluetooth connection request of the second Bluetooth device.

S2606. If the communication distance is greater than the target second search range, do not display the Bluetooth connection request of the second Bluetooth device.

Example 1, assuming that the target second search range is 50cm, and the communication distance of the received second Bluetooth device, such as device A2, is 40cm. Since the communication distance of device A2 is smaller than the target second search range, display the communication distance of device A2. Bluetooth connection request. The process of displaying the Bluetooth connection request can be referred to Figure 22 and will not be described again here.

Example 2: Take the target second search range as 50cm, and take the received second Bluetooth device, such as the communication distance of device B2 as 60cm. Since the communication distance of device B2 is greater than the target second search range, device B2 will not be displayed. Bluetooth connection request. The process of displaying the Bluetooth connection request can be referred to Figure 27. As shown in ① in Figure 27, when displaying video 1, the display device 200 receives the Bluetooth connection request sent by device B2, as shown in ② in Figure 27, and displays Device 200 still only displays video 1 and does not display the Bluetooth connection request, thereby avoiding displaying the Bluetooth connection request sent by the second Bluetooth device whose communication distance exceeds the target second search range, so as to avoid affecting the normal display of video 1.

Thus, the second Bluetooth devices whose communication distance meets the target second search range can be filtered, and only the Bluetooth connection requests of the second Bluetooth devices whose communication distance meets the target second search range are displayed.

In some embodiments, in order to improve the data security of the display device 200 and the privacy security of the user, if the communication distance of the second Bluetooth device is greater than the target second search range, the display device 200 not only does not display the second Bluetooth device Bluetooth connection request, and the display device 200 does not send a feedback signal to the second Bluetooth device. Therefore, the second Bluetooth device can be prevented from discovering the display device 200 based on the feedback information to achieve the effect of hiding the display device 200. Furthermore, once the second Bluetooth device is an illegal Bluetooth device, the second Bluetooth device cannot discover the display device. 200, the display device 200 can be effectively protected.

In some embodiments, the display device 200 may pre-store a white list of the second Bluetooth device, which white list includes device information of each second Bluetooth device that is allowed to display the Bluetooth connection request, and the display device 200 determines the received Bluetooth connection request. Whether the second Bluetooth device belongs to the white list, if it belongs to the white list, the corresponding Bluetooth connection request is displayed; if it does not belong to the white list, the Bluetooth connection request is not displayed, and no feedback is sent to the second Bluetooth device. information.

In some embodiments, the second Bluetooth device on the whitelist may be a second Bluetooth device that has historically displayed Bluetooth connection requests, or may be a second Bluetooth device added by the user, etc. The device information of each second Bluetooth device in the white list is consistent with the currently used device information. For example, the real-time nature of the device information in the white list is maintained by automatically searching and updating the changed device information. This ensures that based on the whitelist, it can be accurately determined whether the second Bluetooth device currently sending the Bluetooth connection request belongs to the whitelist.

For example, as shown in Figure 28, the whitelist includes the device information of device A2, device B2, device C2, and device D2, in order "*****7Pro 5G", "*****8Pro 5G", " 2×××××××××9”, “Little Red’s Tool”. The display device 200 receives a Bluetooth connection request from the second Bluetooth device. If the display device 200 recognizes that the device information of the second Bluetooth device is "*****7Pro 5G", it can determine that the second Bluetooth device is device A2. If it belongs to the whitelist, the Bluetooth connection request will be displayed. The display device 200 receives the Bluetooth connection request of the second Bluetooth device. If the display device 200 recognizes that the device information of the second Bluetooth device is "*****7 4G" and does not belong to the white list, the second Bluetooth device will not be displayed. Bluetooth connection request from a Bluetooth device.

In some embodiments, if the whitelist includes the device information of device B2, device C2, and device D2, but does not include the device information of device A2, that is, the Bluetooth connection request of device A2 is not allowed to be displayed. Therefore, it is initially determined based on the target second search range that the Bluetooth connection request of device A2 can be displayed. However, since device A2 does not belong to the white list, the Bluetooth connection request of device A2 is not displayed. Therefore, the Bluetooth connection requests finally displayed on the user interface can be further restricted based on the whitelist.

In some embodiments, if the communication distance of the second Bluetooth device is within the target second search range, the Bluetooth connection request of the second Bluetooth device is displayed, as shown in ② in Figure 22 . The user can further choose whether to connect the second Bluetooth device. In some embodiments, if the user sends a connection instruction to the display device 200 based on the matching option 2201, a Bluetooth connection is made with the second Bluetooth device, and the second Bluetooth device can be stored. Add the device information of the Bluetooth device to the whitelist, so that when the Bluetooth connection request of the second Bluetooth device is received again, if the second Bluetooth device is within the target second search range, the Bluetooth connection of the second Bluetooth device can be displayed. ask. If the user sends a connection refusal instruction to the display device 200 based on the cancel option 2202, the Bluetooth connection with the second Bluetooth device will not be performed, and the device information of the second Bluetooth device will be stored in a blacklist to avoid receiving the second Bluetooth device again. When the Bluetooth device makes a Bluetooth connection request, even if the second Bluetooth device is within the target second search range, the Bluetooth connection request of the second Bluetooth device is not displayed.

In some embodiments, the second Bluetooth device in the blacklist can be released through manual modification, that is, the released second Bluetooth device is deleted from the blacklist, so that the second Bluetooth device can be displayed when it meets other display conditions. In this case, a Bluetooth connection request is displayed. You can also add the device information of the second Bluetooth device to the blacklist through manual modification.

Thus, the user displays the second search range of the device through the device, so that when receiving a Bluetooth connection request sent by the second Bluetooth device, the Bluetooth connection request is displayed only when the second Bluetooth device is located within the target second search range. , to effectively filter the displayed Bluetooth connection requests, thereby reducing the impact of the displayed Bluetooth connection requests on the user's normal use of the display device, and reducing threats to the data security of the display device and user privacy security.

In some embodiments, the first search range used to limit the display of the searched first Bluetooth devices and the second search range used to limit the display of the received Bluetooth connection requests may use the same set of search ranges. That is to say, the first Bluetooth setting option and the second Bluetooth setting option are the same Bluetooth setting option, and the Bluetooth setting option refers to the entry option corresponding to the search range setting menu. The first control instruction and the second control instruction are the same control instructions. The user sends the control instruction based on the above-mentioned Bluetooth setting option to instruct the display device 200 to display the search range setting menu. In this embodiment, the first search range setting menu and The second search range setting menu is the same search range setting menu, and the display device 200 displays the search range setting menu in response to the control instruction. The search range setting menu includes multiple distance values and/or value input boxes. You may refer to the first search range setting menu shown in Figures 8 and 9, and the second search range setting menu shown in Figures 24 and 25. . The user sets a target search range based on the search range setting menu, and the target search range is used to limit both the first Bluetooth device that performs the display and the second Bluetooth device that displays the Bluetooth connection request. For example, the user sets the target search range to 50cm. After the display device 200 searches for the first Bluetooth device, only the device information of the first Bluetooth device with a communication distance less than or equal to 50cm is displayed; when the display device 200 receives the second Bluetooth device When the device sends a Bluetooth connection request, the Bluetooth connection request will be displayed only when the communication distance of the second Bluetooth device is less than or equal to 50cm, otherwise the Bluetooth connection request will not be displayed.

Therefore, the user can simultaneously limit the first search range and the second search range of the display device 200 with only one setting, which can effectively simplify user operations.
