However, in many situations, the control device may be lost or damaged, in which case, the user may only implement control of the display device through a small number of keys configured on the display device, such as a key for turning on, turning off, or adjusting volume, and fewer functions may be implemented. Then the user needs to purchase the control device adapted to the display device again, which is time consuming and affects the user experience.

It should be noted that the hardware configuration of different display devices may be different, so fig. 2 is merely an exemplary description.

In the related art, control of a display device is generally achieved by a control apparatus specifically configured for the display device. For example, a smart television or the like is controlled by a remote controller. In this case, if the control device is lost or damaged, the user cannot control the display device, or the user can only control the display device through a small number of keys on the display device, so that the use experience of the user is poor. The embodiment of the application provides a display device and a control method of the display device, which can control the display device by adopting Bluetooth equipment (such as a mobile phone and the like) with a Bluetooth signal receiving and transmitting function even without a special control device. The problem that the user cannot display equipment due to the fact that a special control device is lost is solved.

First, a control method of the display device according to the present application will be described. Referring to fig. 3, a flowchart of a control method of a display device according to an embodiment of the present application is provided. It should be noted that the control method according to the present application may be performed by a display device, for example, see the display device shown in fig. 2. Or the control method may be performed by a bluetooth module and a processor included in the display device. Next, referring to fig. 3, description will be made first taking an example in which the control method is performed by the display device. The control method flow of the display device specifically comprises the following steps:

301, a display device receives a bluetooth signal from a bluetooth device.

In some embodiments, multiple antennas may be configured in the display device, and the display device may receive bluetooth signals through the multiple antennas.

302, The display device determines a mapping area in space according to the bluetooth signal and displays at least one control for implementing the control command in the display screen.

Each position point in the mapping area has a mapping relation with at least one control displayed in the display screen. For example, it may be that this point (1, 2, 3) in the mapping area corresponds to control a in the at least one control. In some embodiments, it may be that a plurality of points in the mapping area correspond to one of the at least one control. Continuing with the example above, the two points (1, 2, 4) and (1, 5, 3) in the mapped region may also correspond to control A.

303, When the display device detects that the Bluetooth device is located in the mapping area, determining a target control according to the mapping relation.

The target control can be any one of at least one control displayed in the display screen, the target control corresponds to a target point in the mapping area, and the target point refers to a point corresponding to the position of the Bluetooth device.

In some embodiments, the display device may determine the location of the bluetooth device based on bluetooth signals received from the bluetooth device. If the position of the Bluetooth device is detected to be located in the mapping area, the control corresponding to the position point of the Bluetooth device can be determined to be the target control according to the mapping relation.

304, When the display device determines that the distance between the display device and the bluetooth device is shortened, executing a control command corresponding to the target control.

In some embodiments, the display device may determine the location of the bluetooth device based on bluetooth signals from the bluetooth device, and determine whether the distance between the bluetooth device and the display device is shortened based on a change in the location of the bluetooth device.

In other embodiments, the display device may also determine whether the distance between the bluetooth device and the display device is shortened based on the signal strength of the received bluetooth signal. For example, it may be determined that the distance of the bluetooth device from the display device is shortened when the signal strength of the bluetooth signal is increased.

In some embodiments, the display device may also first determine that no control command from the control means has been received before the control of the display device is effected by the bluetooth device. For example, after the display device is started, whether a control command from the control device is received is detected, and if the control command from the control device is not received within a set period of time, a bluetooth signal may be received through the bluetooth module. Or in another possible case, the display device may directly receive the bluetooth signal through the bluetooth module after being powered on, and determine the location of the bluetooth device that transmits the bluetooth signal according to the received bluetooth signal. Further, the display device judges whether a control command from the control device is received or not within the set time period. If not, control of the display device may be achieved using a Bluetooth device, for example, see the process shown in FIG. 3. In order to facilitate understanding the foregoing solution, referring to fig. 4, a flowchart of a control method for determining a display device according to an embodiment of the present application specifically includes:

401, the display device is turned on.

In some embodiments, the display device may perform a power-on action in response to a user operation of a physical key on the display device.

402, The display device receives a bluetooth signal via the bluetooth module and determines a location of the bluetooth device that transmitted the bluetooth signal based on the bluetooth signal.

403, The display device determines whether a control command from the control device is received within a set period of time.

If yes, corresponding operation is executed according to the control command.

If not, then step 404 is continued.

404, The display device implements the control command using a bluetooth device.

In some embodiments, the specific process of implementing the control command by the bluetooth device may be referred to in fig. 3, which is not described herein.

Based on the scheme, the display device starts to realize the control command by the Bluetooth device after determining that the control command from the control device is not received in a period of time. The problem that received commands are disordered and the commands to be executed cannot be determined due to the fact that control commands are realized through Bluetooth equipment under the condition that a control device is available is avoided.

In some embodiments, when the display device initiates implementation of a control command with the bluetooth device, the mapping area may first be determined based on bluetooth signals from the bluetooth device. Since the quality of the bluetooth signal detected by the display device is higher the closer the bluetooth device is to the display device, the use experience of the user may be reduced if the bluetooth device is too close to the display device. Therefore, the display device may first determine the effective distance and construct the mapping region within the effective distance before determining the mapping region. The range of the effective distance is understood to be a sphere with the display device as the center of the sphere and the effective distance as the radius. In one possible way of determining the effective distance, an optimal distance may be pre-configured, i.e. an optimal distance between the display device and the bluetooth device in order to ensure the quality of the bluetooth signal beyond which the quality of the received bluetooth signal may decrease, the location of the bluetooth device cannot be determined from the bluetooth signal. And when the distance between the Bluetooth device and the display device is detected to be smaller than or equal to the optimal distance, the distance between the Bluetooth device and the display device at the moment is taken as an effective distance. As an alternative, the display device may determine the distance between the bluetooth device and the display device by calculating the signal strength (RECEIVED SIGNAL STRENGTH Indication, RSSI) of the received bluetooth signal, and take the distance as the effective distance when it is determined that the distance is less than or equal to the preset optimal distance. For example, referring to fig. 5, a method flow for setting an effective distance according to an embodiment of the present application specifically includes:

501, the display device calculates the signal strength of the currently received bluetooth signal.

In some embodiments, the display device may display an optimal signal strength corresponding to a preset optimal distance in the display interface (i.e., when the bluetooth signal reaches the optimal strength, it represents that the distance between the bluetooth device and the display device reaches the optimal distance). The display device may also display the signal strength of the currently detected bluetooth signal in the display screen. For example, see the display interface shown in fig. 6A.

In some embodiments, due to the instability of the bluetooth signal, the display device may also obtain the signal strength of the bluetooth signal received during a period of time, calculate an average value of the signal strengths of the bluetooth signal during the period of time, and use the average value of the signal strengths as the signal strength of the currently received bluetooth signal.

502, The display device determines whether the currently received signal strength is greater than an optimal signal strength.

If yes, proceed to step 503.

If not, then step 504 is continued.

503, The display device takes the current distance from the bluetooth device as the effective distance.

In some embodiments, the display device may determine the distance of the bluetooth device from the display device based on the signal strength of the bluetooth signal. For example, the correspondence between the signal intensity and the distance may be preconfigured in the display device, and the distance corresponding to the calculated intensity may be determined according to the correspondence.

In other embodiments, the display device may determine the location of the bluetooth device based on the bluetooth signal and then determine the distance of the bluetooth device from the display device by calculation. For example, the display device may receive a bluetooth signal from the bluetooth device through a bluetooth module included therein, detect a fixed frequency extension signal (Constant Tone Extension, CTE) included In the bluetooth signal, and acquire In-phase Quadrature (IQ) data for positioning. The display device may then determine a phase difference of each antenna group included in the bluetooth module according to the IQ data, and then determine an arrival angle of each antenna group according to the phase difference of each antenna group. Further, the display device may determine the location of the bluetooth device based on the location of each antenna group and the angle of arrival of each antenna group. And finally, calculating the difference between the position of the Bluetooth device and the position of the display device to obtain the distance between the Bluetooth device and the display device.

504, The display device displays the prompt message in the display screen.

The prompting information is used for prompting a user of the Bluetooth device to approach the Bluetooth device to the display device. As one example, the display device may display a display interface as shown in fig. 6B to prompt the user to bring the bluetooth device close to the display device.

After the display device displays the prompt information, the method may return to step 501, and continue to calculate the signal strength of the bluetooth signal until the calculated signal strength of the bluetooth signal is greater than the preset optimal signal strength.

In some embodiments, after determining the effective distance, the display device may further determine the mapping region within the effective distance by way of interface interactions. In some embodiments, the detection area may be first determined by way of interface interactions, where the detection area is larger in extent than the mapping area, which is located within the detection area. The display device may use a set rule to set a part of the detection area as the mapping area after determining the detection area. For example, referring to fig. 7, a method flow for determining a detection area according to an embodiment of the present application specifically includes:

701, the display device displays a display interface in the display screen for guiding the user for position calibration.

For example, the display device may display a display interface as shown in fig. 8A in the display screen. Four calibration positions are included in the display interface shown in fig. 8A.

The display device displays in the display screen the location in the display screen to which the current bluetooth device maps.

In some embodiments, the display device may obtain a location in the display screen where the bluetooth device is vertically mapped. For example, a perpendicular may be drawn from a location point where the bluetooth device is located to a plane where the display screen is located, and a point where the perpendicular intersects the display screen may be mapped to a location in the display screen as the current bluetooth device. In some embodiments, the display device may display dots, arrows, triangles, or the like in the display interface to refer to the location of the bluetooth device, for example, see the display interface shown in fig. 8B.

The display device displays, in a display screen, instruction information for instructing to perform calibration 703.

For example, describing calibration for calibration location a, reference may be made to the display interface shown in fig. 8C. In the display interface shown in fig. 8C, a display interface for instructing calibration for the calibration-performed position a is displayed.

704, The display device saves the position of the bluetooth device and the signal strength of the bluetooth signal when detecting that the bluetooth device is located in the calibration position.

For example, when the bluetooth device is in the calibration position a, the display device may calculate the position W1 of the bluetooth device at this time. In some embodiments, the location of the Bluetooth device may be calculated in the manner described above with respect to step 503 of FIG. 5. Further, the display device may acquire the signal strength R1 of the bluetooth signal sent by the bluetooth device at this time. Similarly, when the bluetooth device is located in the calibration positions B, C and D, the position of the bluetooth device and the signal strength of the bluetooth signal may be obtained and stored in the same manner.

705, The display device determines the detection area in combination with the location of the bluetooth device and the signal strength of the bluetooth signal.

In some embodiments, for four calibration positions, the display device may obtain the positions of the four groups of bluetooth devices and the signal strengths of the bluetooth signals, for example:

calibration position a: (W1, R1), calibration position B: (W2, R2), calibration position C: (W3, R3), calibration position D: (W4, R4).

The display device may determine the detection area in combination with two factors, location and signal strength. For ease of understanding, referring to fig. 8D, a schematic diagram of a detection area is provided in an embodiment of the present application, and cuboid ABCDEFGH shown in fig. 8D is the detection area. It should be noted that fig. 8D is only an example, and the position and shape of the detection area in the embodiment of the present application are not particularly limited.

In some scenarios, after determining the detection region, the display device may further determine a mapping region according to a preconfigured rule, which may be part of the detection region. For easy understanding, fig. 8E may be referred to as a schematic diagram of a mapping area provided in an embodiment of the present application, where cuboid ABCDEFGH shown in fig. 8E is a detection area, and cuboid B 'BD' DF 'FH' H is a mapping area. It should be noted that fig. 8E is only an example, and the position of the mapping region in the detection region and the shape of the mapping region are not particularly limited in the present application.

In some embodiments, the display device may display at least one control for implementing the control command in the display screen after determining the detection region and the mapping region. The following describes a method for displaying at least one control in connection with some specific scenarios.

In some scenarios, the number and content of the controls included in the display interface may be preset, for example, see the display interface shown in fig. 9, where controls for implementing control commands of increasing volume, decreasing volume, confirming, returning to home page, sliding left, sliding right, sliding up, and sliding down are included. In some embodiments, there may be a mapping relationship between each control displayed in the display interface and each point in the mapping region. A plurality of points in the mapped area may correspond to a control in the display interface. For example, points A-D in the mapping region may correspond to a first control, points E-H in the mapping region may correspond to a second control, and so on. In some embodiments, the mapping relationship that each control may exist with each point in the mapping area may be: when the display device detects that the Bluetooth device is located at a certain point of the mapping area, the Bluetooth device can be considered to select a control corresponding to the certain point.

In order to ensure the accuracy of interface interaction, misoperation is avoided. In some scenarios, the display device may also space adjacent controls by a certain distance when displaying the controls. For example, see the display interface shown in fig. 10. In some embodiments, the length of the distance between adjacent controls may be set according to the positioning accuracy of the bluetooth signal, and the distance between any two adjacent controls may be equal or unequal.

In other scenarios, if at least one control is always displayed in the display interface, other content displayed on the display interface may be blocked. For example, when a user views a video, if at least one control is always displayed in the display interface, the content of the video that the user views may be blocked, so that the viewing experience of the user is poor. Based on this, the embodiment of the application provides that the display device can continuously display at least one control when determining that the position of the bluetooth device is located in the mapping area. If the display device determines that the Bluetooth device is located outside the mapping area, after at least one control is displayed for a set time period, the at least one control is not displayed any more, and other contents of the shielding display interface are prevented from affecting the viewing of the user.

In some scenarios, if the position of the bluetooth device changes, the display position of each control displayed in the display screen may not be located right in front of the user of the bluetooth device, so that the use experience is poor in the process of interface interaction of the user through the bluetooth device. For example, see the scene diagram shown in (a) in fig. 11. Based on the above, the application provides an interface interaction scheme, and when the display device detects that the position of the Bluetooth device is no longer in front of at least one control displayed in the display screen, the display position of the at least one control in the display screen can be moved to the position in front of the Bluetooth device so as to be convenient for a user to watch. Continuing with the above example, the scene after the display device moves the display position of the at least one control in the display screen may be referred to as a scene diagram shown in (b) of fig. 11. In some embodiments, the display device may utilize the effective distance introduced in fig. 5 to determine whether the location of the bluetooth device is directly in front of at least one control displayed in the display screen. For example, the display device may determine whether a distance between the bluetooth device and the at least one control is less than or equal to a valid distance, and if so, may determine that the bluetooth device is located directly in front of the at least one control displayed in the display screen. The foregoing description, for purposes of explanation, will be presented in terms of particular embodiments. For example, referring to fig. 12, a process of an interface interaction method provided in an embodiment of the present application specifically includes:

1201, the display device determines the location of the bluetooth device from bluetooth signals from the bluetooth device.

In some embodiments, the process of determining the location of the bluetooth device by the display device according to the bluetooth signal may be described in step 503 of fig. 5, which is not described herein.

In some embodiments, in order to avoid the problem that the calculated position of the bluetooth device is inaccurate due to factors such as object shielding or wall reflection, the display device may also calculate the signal strength of the bluetooth signal, reject the bluetooth signal whose signal strength does not meet the set requirement (for example, may set to reject the bluetooth signal whose signal strength is too small), and calculate the position of the bluetooth device by using the bluetooth signal whose signal strength meets the set requirement.

1202, The display device calculates a distance of the bluetooth device from at least one control displayed in the display screen.

For example, the display device determines that the bluetooth device has a position (1, 3, 6) and at least one control has a position (0, 3), and then the display device may calculate a distance between the two points, that is, a distance between the bluetooth device and the at least one control. This distance will be simply referred to as distance a hereinafter for convenience of description.

1203, The display apparatus determines whether the distance a is greater than the effective distance.

If yes, proceed to step 1204.

If not, no operation is performed.

1204, The display device moves a display position of at least one control in the display screen.

After moving the display position of the at least one control, the display device may return to step 1201 until the display device determines that the calculated distance a is less than or equal to the effective distance.

Based on the scheme, the display device can move the display position of at least one control displayed in the display screen according to the position of the user of the Bluetooth device, so that the display position of at least one control in the display screen can be kept right in front of the user, and the viewing experience of the user is improved.

In the above, the embodiments of the present application provide a plurality of display methods for displaying at least one control, and it should be noted that the plurality of display methods may be used alone or in combination.

In some embodiments, the display device may continuously detect the location of the bluetooth device after determining the detection area and the mapping area from the bluetooth signal and displaying at least one control for implementing the control command in the display interface. To conserve computing resources of the display device, in some embodiments, the display device may also periodically detect when detecting the location of the bluetooth device (e.g., the location of the bluetooth device may be calculated once every interval setting period). In other embodiments, the display device may also set different detection periods for different areas where the bluetooth device is located. For example, when the display device determines that the bluetooth device is located outside the detection area, it may be set to perform a position calculation of the bluetooth device once every interval period T1. When the display device determines that the bluetooth device is located within the detection area and outside the mapping area, the location calculation of the bluetooth device may be set to be performed once per interval period T2. When the display device is located in the mapping area, it may be set to perform the position calculation of the bluetooth device once every interval period T3. Wherein T1 > T2 > T3.

In some embodiments, if the display device detects that the location of the bluetooth device is located in the mapping area, a target control corresponding to a point of the location of the current bluetooth device may be determined (which may be understood as a target control being a control to be selected by the bluetooth device). In some embodiments, the display device may also make a special display of the target control to indicate that the target control is selected. For example, when the target control is "volume+", reference may be made to the display interface shown in fig. 13. Further, after determining the target control, the display device may execute the control command corresponding to the target control when determining that the distance between the bluetooth device and the display device is shortened, and stop executing the control command corresponding to the target control when determining that the distance between the bluetooth device and the display device is increased. To further understand the foregoing solution, the following description is provided with reference to a specific embodiment, and referring to fig. 14, a flowchart of a method for implementing a control command according to an embodiment of the present application specifically includes:

1401, the display device determines that the bluetooth device is located in the mapping area according to the bluetooth signal.

1402, The display device calculates the position of the bluetooth device and the signal strength of the bluetooth signal, and determines a target control corresponding to the position of the bluetooth device.

The display device determines whether the distance to the bluetooth device is shortened 1403.

In one possible approach, the display device may determine whether the distance is shortened based on the signal strength of the bluetooth signal. For example, the display device may determine that the distance from the bluetooth device is shortened when the signal strength becomes large. In another possible way, the display device may determine whether the distance from the bluetooth device is shortened based on the location of the bluetooth device.

In some embodiments, the display device may further determine that the distance of the bluetooth device from the display device is shortened when it is determined that the signal strength of the bluetooth signal is increased and it is determined that the calculated location of the bluetooth device is close to the display device.

If so, proceed to step 1404.

If not, no operation is performed.

1404, The display device executes the control command corresponding to the target control, and continues to calculate the position of the bluetooth device and the signal strength of the bluetooth signal.

The display device may determine a distance to the bluetooth device based on the calculated location of the bluetooth device and the signal strength of the bluetooth signal.

1405, The display device determines whether the distance from the bluetooth device increases.

If yes, proceed to step 1406.

If not, return to step 1404.

1406, The display device stops executing the control command corresponding to the target control.
