Technical Field

The present application relates to the field of bluetooth technology, and in particular, to a display device and a control method for the display device.

Background

Currently, the control function for the display device is generally implemented based on a control means (e.g., a remote controller). However, in many scenarios, the control device may be lost or damaged, and in this case, the user may only control the display device through a small number of keys configured on the display device, for example, the keys for turning on, turning off, or adjusting the volume may implement fewer functions. Then, the user is required to purchase a control device adapted to the display device, which wastes time and affects the user experience.

It should be noted that the hardware configuration of different display devices may be different, and therefore fig. 2 is only used as an exemplary description.

In the related art, control of a display device is generally achieved using a control apparatus specifically configured for the display device. For example, a smart tv set or the like is controlled by a remote controller. In this case, if the control device is lost or damaged, the user may not control the display device, or the user may only control the display device through a small number of keys on the display device, so that the user experience is poor. The embodiment of the application provides a display device and a control method of the display device, and provides that a Bluetooth device (such as a mobile phone and the like) with a function of receiving and transmitting Bluetooth signals can be adopted to control the display device even if a special control device is not provided. The problem that the user cannot display the equipment due to the fact that the special control device is lost is solved.

First, a control method of a display device proposed in 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 proposed in the present application may be executed by a display device, for example, refer to the display device shown in fig. 2. Alternatively, the control method may be executed by a bluetooth module and a processor included in the display device. Next, referring to fig. 3, description will be first made by taking an example in which the control method is executed by the display device. The control method of the display device specifically comprises the following steps:

301, the 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.

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

And 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 (1, 2, 3) of the mapping region corresponds to control a of the at least one control. In some embodiments, it may be that a plurality of points in the mapping region correspond to one of the at least one control. Continuing with the above example, two points (1, 2, 4) and (1, 5, 3) in the mapping region may also correspond to control A.

And 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.

And 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 position of the bluetooth device according to the bluetooth signal from the bluetooth device, and determine whether the distance between the bluetooth device and the display device is shortened according to the change of the position of the bluetooth device.

In other embodiments, the display device may further determine whether the distance between the bluetooth device and the display device is shortened according to 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 apparatus has been received before control of the display device is effected by the bluetooth device. For example, the display device may detect whether a control command from the control apparatus is received after being turned on, and may receive a bluetooth signal through the bluetooth module if the control command from the control apparatus is not received within a set time period. Or, in another possible case, after the display device is powered on, the display device may directly receive the bluetooth signal through the bluetooth component, and determine the location of the bluetooth device that transmits the bluetooth signal according to the received bluetooth signal. Further, the display device determines whether the control command from the control device is received within the set time period. If not, the control of the display device may be implemented using a bluetooth device, for example, as shown in fig. 3. To facilitate understanding of the above scheme, referring to fig. 4, a flowchart of a control method for determining a display device provided in 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 an entity key on the display device.

402, the display device receives the bluetooth signal via the bluetooth component and determines the location of the bluetooth device that sent the bluetooth signal based on the bluetooth signal.

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

If yes, executing corresponding operation according to the control command.

If not, continue with step 404.

And 404, the display device adopts a Bluetooth device to realize the control command.

In some embodiments, a specific process of implementing the control command through the bluetooth device may refer to fig. 3 described above, and is not described herein again.

Based on the scheme, the display device starts to adopt the Bluetooth device to realize the control command after determining that the control command from the control device is not received within a period of time. The problem that the command to be executed cannot be determined due to confusion of the received command caused by realizing the control command through the Bluetooth device under the condition that the control device is available is solved.

In some embodiments, when the display device starts to implement the control command using the bluetooth device, the mapping region may be first determined according to a bluetooth signal from the bluetooth device. Since the closer the bluetooth device is to the display device, the higher the quality of the bluetooth signal detected by the display device, but if the bluetooth device is too close to the display device, the user experience may be degraded. Therefore, the display device may first determine the effective distance and construct the mapping region within the range of the effective distance before determining the mapping region. The range of the effective distance may be understood as a sphere having the display device as a center of sphere and the effective distance as a radius. In a possible implementation manner of determining the effective distance, an optimal distance may be preconfigured, that is, the optimal distance between the display device and the bluetooth device is determined to ensure the quality of the bluetooth signal (if the quality of the received bluetooth signal is reduced beyond the optimal distance, the position of the bluetooth device cannot be determined according to the bluetooth signal). And when detecting that the distance between the Bluetooth device and the display device is smaller than or equal to the optimal distance, taking the distance between the Bluetooth device and the display device at the moment as an effective distance. As an alternative, the display device may determine the distance between the bluetooth device and the display device by calculating a Received Signal Strength Indication (RSSI) of the bluetooth Signal, and when it is determined that the distance is less than or equal to a preset optimal distance, the distance is taken as an effective distance. Exemplarily, referring to fig. 5, a method flow for setting an effective distance provided by the embodiment of the present application specifically includes:

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

In some embodiments, the display device may display an optimal signal strength corresponding to the preset optimal distance in the display interface (i.e., when the bluetooth signal reaches the optimal strength, 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 further obtain the signal strength of the bluetooth signal received within a period of time, calculate an average value of the signal strength of the bluetooth signal within the period of time, and use the average value of the signal strength as the signal strength of the currently received bluetooth signal.

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

If so, proceed to step 503.

If not, continue with step 504.

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

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 display device may be configured with a correspondence relationship between signal intensity and distance in advance, and determine a distance corresponding to the calculated intensity according to the correspondence relationship.

In other embodiments, the display device may determine the location of the bluetooth device based on the bluetooth signal and then determine the distance between the bluetooth device and 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 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 for each antenna group comprised by the bluetooth component from the IQ data, and then determine an angle of arrival for each antenna group from the phase difference for each antenna group. Further, the display device may determine the location of the bluetooth device according to the location of each antenna group and the angle of arrival of each antenna group. And finally, calculating the difference value between the position of the Bluetooth device and the position of the display device, namely the distance between the Bluetooth device and the display device.

And 504, displaying prompt information in a display screen by the display device.

Wherein the prompt message is used for prompting a user of the Bluetooth device to bring the Bluetooth device close to the display device. As an 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 message, the process returns to step 501 to continue calculating 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 range of the effective distance by means of interface interaction. In some embodiments, the detection area may be first determined by means of interface interaction, the detection area having a larger extent than the mapping area, and the mapping area being located within the detection area. The display device may adopt a set rule to take 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 provided in the embodiment of the present application specifically includes:

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

For example, the display device may display a display interface as shown in fig. 8A in a display screen. The display interface shown in FIG. 8A includes four calibration positions.

The display device displays the location in the display screen to which the current bluetooth device is mapped in the display screen 702.

In some embodiments, the display device may obtain a position in the display screen to which the bluetooth device is vertically mapped. For example, a perpendicular line may be drawn from a position point where the bluetooth device is located to a plane where the display screen is located, and a point where the perpendicular line intersects with the display screen may be mapped to a position 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 indicate the location of the bluetooth device, for example, see the display interface shown in fig. 8B.

703, the display device displays indication information for indicating to perform calibration in the display screen.

For example, taking the calibration for the calibration position a as an example, 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 position a is displayed.

The display device saves the location of the bluetooth device and the signal strength of the bluetooth signal when it detects that the bluetooth device is in the calibration position 704.

For example, when the bluetooth device is located at calibration position a, the display device may calculate the position W1 of the bluetooth device at that time. In some embodiments, the location of the bluetooth device may be calculated in the manner described above in connection with 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 that time. Similarly, when the bluetooth device is located at the calibration positions B, C and D, the bluetooth device's position and the bluetooth signal's signal strength may be obtained and stored in the same manner.

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

In some embodiments, the display device may acquire the positions of four sets of bluetooth devices and the signal strengths of the bluetooth signals for four calibration positions, 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 both location and signal strength factors. For easy understanding, referring to fig. 8D, a schematic diagram of a detection area provided in the embodiment of the present application is shown, and a rectangular parallelepiped ABCDEFGH shown in fig. 8D is the detection area. It should be noted that fig. 8D is only an example, and the position and the shape of the detection area are not particularly limited in the embodiment of the present application.

In some scenarios, the display device may further determine a mapping region according to a preconfigured rule after determining the detection region, and the mapping region may be a portion of the detection region. For convenience of understanding, referring to fig. 8E, a schematic diagram of a mapping region provided in the embodiment of the present application is shown, where a rectangular parallelepiped ABCDEFGH shown in fig. 8E is a detection region, and a rectangular parallelepiped B 'BD' DF 'FH' H is a mapping region. It should be noted that fig. 8E is only an example, and the present application does not specifically limit the position of the mapping region in the detection region and the shape of the mapping region.

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. In the following, a display method of at least one control is described with reference to 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, which includes controls for implementing control commands such as volume up, volume down, confirmation, homepage return, left slide, right slide, up slide, and down slide. In some embodiments, each control displayed in the display interface may have a mapping relationship with each point in the mapping region. It may be that a plurality of points in the mapping area 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 have with each point in the mapping region may be: when the display device detects that the bluetooth device is located at a certain point of the mapping area, it may be considered that the bluetooth device selects the control corresponding to the point.

In order to ensure the accuracy of interface interaction and avoid misoperation. In some scenarios, when the display device displays the above-mentioned controls, the adjacent controls may also be spaced apart by a certain distance. For example, reference may be made to 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 in the display interface may be blocked. For example, when a user watches a video, if at least one control is always displayed in the display interface, the content of the video watched by the user may be blocked, so that the watching experience of the user is poor. Based on this, the embodiment of the present application provides that the display device may continuously display the at least one control when determining that the location of the bluetooth device is located within the mapping area. If the display device determines that the Bluetooth device is located outside the mapping area, the display device can display the at least one control no longer after the at least one control reaches the set duration, so that the influence of other contents on the shielding display interface on the user viewing is avoided.

In some scenarios, if the position of the bluetooth device changes, the display positions of the controls displayed in the display screen may no longer be directly in front of the user of the bluetooth device, so that the user experiences poor user experience during the interface interaction process through the bluetooth device. For example, see a scene diagram shown in (a) in fig. 11. Based on this, the application provides an interface interaction scheme, and when detecting that the position of the bluetooth device is no longer directly in front of the at least one control displayed in the display screen, the display device may move the display position of the at least one control in the display screen to be directly in front of the position of the bluetooth device for the user to view. 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 refer to the scene diagram shown in (b) in 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 the effective 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. For ease of understanding, the foregoing is described in connection with specific embodiments. Exemplarily, referring to fig. 12, a flow of an interface interaction method provided in the embodiment of the present application specifically includes:

1201, the display device determines the location of the bluetooth device based on the bluetooth signal from the bluetooth device.

In some embodiments, the process of determining the position of the bluetooth device by the display device according to the bluetooth signal may be described in the related description of step 503 of fig. 5, and will not be described herein again.

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

And 1202, the display device calculates the distance between the Bluetooth device and at least one control displayed in the display screen.

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

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

If so, proceed to step 1204.

If not, no operation is carried out.

And 1204, the display device moves the 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 above scheme, the display device can move the display position of the 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 the 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.

As described above, in the embodiment of the present application, multiple display methods are provided in combination with a display of at least one control, and it should be noted that the multiple display methods may be used alone or in combination.

In some embodiments, the display device may continuously detect the position of the bluetooth device after determining the detection region and the mapping region according to the bluetooth signal and displaying at least one control for implementing the control command in the display interface. In order to save the computing resources of the display device, in some embodiments, the display device may also periodically detect when detecting the position of the bluetooth device (e.g., the position of the bluetooth device may be calculated once every set period). In other embodiments, the display device may set different detection periods for different areas where bluetooth devices are located. For example, when the display device determines that the bluetooth device is located outside the detection area, it may be set that the position calculation of the bluetooth device is performed once per the interval period T1. When the display device determines that the bluetooth device is located inside the detection area and outside the mapping area, it may be set to perform the position calculation of the bluetooth device once per the interval period T2. When the display device is located within the mapping region, it may be set to perform the position calculation of the bluetooth device once per the 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 current location of the bluetooth device may be determined (it may be understood that the target control is a control to be selected by the bluetooth device). In some embodiments, the display device may also display the target control in a special display 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. In order to further understand the above solution, the following description is made with reference to a specific embodiment, and with reference to fig. 14, a flowchart of a method for implementing a control command provided by the embodiment of the present application specifically includes:

1401, the display device determines from the bluetooth signal that the bluetooth device is located within the mapped area.

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.

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

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 to the bluetooth device is shortened when the signal strength becomes large. In another possible manner, the display device may determine whether the distance to the bluetooth device is shortened according to the location of the bluetooth device.

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

If so, then step 1404 continues.

If not, no operation is carried out.

And 1404, executing the control command corresponding to the target control by the display device, and continuously calculating the position of the Bluetooth device and the signal intensity of the Bluetooth signal.

The display device may determine a distance to the bluetooth device according to the calculated position of the bluetooth device and the signal strength of the bluetooth signal.

1405, the display device determines whether the distance to the bluetooth device increases.

If so, proceed to step 1406.

If not, return to step 1404.

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