[0002] In traditional display scenarios, such as televisions, remote controls primarily power the TV on and off, switch display content, and adjust the volume. Remote controls are typically directional, transmitting control signals. A receiver on the TV receives these signals. The receiver, in conjunction with the remote, measures the horizontal and / or vertical angle of incidence of the remote on the TV receiver. However, when the remote is at a large angle to the receiver, the receiver's angle measurement error can increase, potentially resulting in poor signal quality and impacting communication between the remote and the TV.

[0023] It should be noted that the terms "first" and "second" in the specification, claims and drawings of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. In the specification, claims and drawings of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the term "multiple" in the specification, claims and drawings of this application refers to two or more units.

[0024] It is understood that the connection relationships described in this application refer to direct or indirect connections. For example, A and B are connected or A is electrically connected to B. This can mean that A and B are directly connected, or that A and B are indirectly connected through one or more other electrical components. For example, A and C can be directly connected, and C can be directly connected to B, so that A and B are connected through C.

[0025] It should also be noted that the method disclosed in the embodiments of the present application or the method shown in the flowchart includes one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchanged with each other, and some steps can also be deleted.

[0026] The following will describe some embodiments with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0027] In traditional display scenarios, such as televisions, the remote control mainly plays the role of turning the TV on and off, switching displayed content, adjusting the volume, etc. The remote control is usually a directional remote control that can transmit control signals. A receiver is set up on the TV end to receive the control signals. The receiver, together with the remote control, can measure the incident angle of the remote control in the horizontal and / or vertical directions of the TV receiver. However, when the remote control and the receiver are at a large angle, the angle measurement error of the receiver is likely to become larger, which can easily cause poor quality of the received signal and affect the communication between the remote control and the TV. For example, in a conference application scenario, the speech content is presented through the display. In order not to block the audience's view, the speaker usually stands on the side of the display to give a speech. At this time, the angle between the remote control held by the speaker and the display receiver is large, resulting in poor communication between the remote control and the display, and may even cause communication interruption, resulting in a poor user experience.

[0028] In view of this, embodiments of the present application provide a signal receiver, a signal receiving method, and a display device for a display, so as to achieve adaptive rotation tracking of a signal source and improve communication stability with the signal source.

[0029] See also Figure 1 and Figure 2The present invention provides a signal receiver 100 for use with a display 200. In some embodiments, the display 200 may be, but is not limited to, a television, a projector, a graphical user interface (GUI), an oscilloscope, a gaming device, etc., and may have a display surface. The display 200 may establish a wireless communication connection with a signal source 300 through the signal receiver 100 to achieve interaction, such as exchanging signals and data. The signal source 300 may be, but is not limited to, a remote control, a signal transmitter, an intelligent control device, etc., and may transmit signals. The display 200 receives the signals transmitted by the signal source 300 through the signal receiver 100, thereby achieving communication and interaction between the display 200 and the signal source 300.

[0030] Please also refer to Figure 2 and Figure 3 The signal receiver 100 may include an antenna array 12 , a housing 14 , a rotating base 20 and a processor 30 .

[0031] The antenna array 12 is disposed within the housing 14 and can be used to receive signals transmitted by the signal source 300. In some embodiments, the antenna array 12 may have a receiving surface for receiving signals transmitted by the signal source. In some embodiments, when the angle of incidence of the signal source relative to the antenna array 12 is small, or when the antenna array 12 is oriented toward the signal source, better signal reception quality can be achieved. For example, when the signal source is approximately perpendicular to the antenna array 12, the antenna array 12 can achieve better signal reception quality. However, when the angle of incidence of the signal source relative to the antenna array 12 is large, the signal reception quality of the antenna array 12 may decrease accordingly.

[0032] In some embodiments, the antenna array 12 may be, but is not limited to, an ultra-wideband (UWB) antenna array, which can perform wireless communications based on an extremely wide frequency band (e.g., greater than 500 MHz), and achieve data transmission by receiving short pulse signals of the nanosecond (ns) level from a signal source. The antenna array 12 can measure the position and attitude angle of the signal source based on UWB positioning technology.

[0033] The antenna array 12 can be composed of multiple antennas, which are spaced apart and arranged on the housing 14. In some embodiments, the antenna array 12 can be formed by connecting at least two antennas to form a receiving plane. In some embodiments, the housing 14 can include a dielectric substrate that can support the antenna array 12 and provide functions such as feeding and grounding. In some embodiments, the antenna array 12 can be spaced apart along the surface of the housing 14, and the receiving plane of the antenna array 12 can be the surface of the housing 14.

[0034] In other embodiments, the antenna array 12 may also include a larger number of antennas to achieve more communication functions. The number of antennas in the antenna array 12 may be set according to actual needs, and this application does not impose any restrictions on this.

[0035] Please also refer to Figure 1 and Figure 2 The rotating base 20 can be set on the display 200, and the shell 14 is set on the rotating base 20. The rotating base 20 is used to rotatably support the shell 14 on the display 200.

[0036] In some embodiments, the rotating base 20 may include a base 22 and a rotating portion 24. The base 22 may be fixedly mounted on the display 200, for example, fixedly mounted on the top of the display 200. The rotating portion 24 rotatably connects the housing 14 and the base 22. The rotating portion 24 is configured to drive the housing 14 and the antenna array 12 to rotate horizontally relative to the display 200. In some embodiments, the rotating portion 24 may include a driving element and a power supply element, and may drive the housing 14 and the antenna array 12 to rotate horizontally relative to the base 22 and the display 200 to adjust the angle of the antenna array 12.

[0037] The processor 30 is disposed in the housing 14 and is respectively connected to the antenna array 12 and the rotating base 20, and is used to obtain signals and data from the antenna array 12 and control the operation of the rotating base 20. In some embodiments, the processor 30 can be used to obtain the incident angle of the signal source relative to the antenna array 12 based on the signal received by the antenna array 12. When the angle of incidence of the antenna array 12 of the signal source is greater than or equal to a preset angle threshold, the processor 30 controls the rotating base 20 to rotate to drive the antenna array 12 on the housing 14 to rotate until the incident angle of the signal source is less than the angle threshold, so that the antenna array 12 is better oriented towards the signal source, thereby ensuring that the antenna array 12 can obtain a smaller relative angle with the signal source, thereby ensuring that the antenna array 12 can obtain a better receiving signal angle, enabling the antenna array 12 to adaptively track the signal source, and improving the communication stability between the signal receiver 100 and the signal source. The incident angle of the signal source can be the signal incident angle of the signal source relative to the receiving plane of the antenna array 12, that is, the incident angle of the signal source can be the angle between the line connecting the signal source to the antenna array 12 and the normal of the antenna array 12.

[0038] Please also refer to Figure 4In some embodiments, the processor 30 may be configured to obtain an incident angle of the signal source 300 relative to the antenna array 12 based on a signal received by the antenna array 12. In some embodiments, the antenna array 12 includes at least two antennas, wherein a line connecting the at least two antennas forms a signal receiving plane 101 of the antenna array 12, the antenna array 12 has a normal line 103, the normal line 103 is perpendicular to the midpoint m of the receiving plane 101, a line connecting the signal source 300 to the midpoint m of the receiving plane 101 forms a signal source line 105, and an incident angle (or horizontal angle) of the signal source 300 relative to the antenna array 12 is the angle between the line connecting the signal source 300 to the midpoint m of the receiving plane 101 and the normal line 103 of the antenna array 12, that is, the incident angle of the signal source 300. θ t is the angle between the signal source line 105 and the normal line 103 of the antenna array 12 .

[0039] In some embodiments, in the initial state of the antenna array 12, the antenna array 12 is arranged along the display plane of the display 200, that is, the receiving plane of the antenna array 12 can be coplanar or parallel to the display plane of the display 200. After the rotating base 20 drives the antenna array 12 to rotate, the receiving plane of the antenna array 12 forms a certain angle with the display plane of the display 200. When the antenna array 12 receives a signal from a signal source, the processor 30 can obtain the current rotation angle of the antenna array 12. θ r , the current rotation angle is the current angle between the antenna array 12 and the display plane of the display 200.

[0040] In some embodiments, the processor 30 determines the current relative angle of the signal source to the antenna array 12 by comparing the incident angle of the signal source relative to the antenna array 12 with a preset angle threshold. When it is determined that the incident angle of the signal source relative to the antenna array 12 is greater than or equal to the preset angle threshold, it can be determined that the relative angle between the antenna array 12 and the signal source is large, and the antenna array 12 needs to be adjusted to face the signal source. In some embodiments, the preset angle threshold can be, but is not limited to, 20 degrees. When the processor 30 determines that the incident angle of the signal source relative to the antenna array 12 is greater than or equal to the preset angle threshold, for example, , the processor 30 controls the rotating base 20 to rotate to drive the antenna array 12 on the housing 14 to rotate until the incident angle of the signal source is less than the angle threshold, so that the antenna array 12 is better oriented towards the signal source, thereby ensuring that a smaller relative angle can be obtained between the antenna array 12 and the signal source. In some embodiments, the angle of the antenna array 12 on the housing 14 can be calculated by adjusting the rotating base 20 to rotate: Formula (1) in, θt is the incident angle of the signal source. It is understood that after adjustment to this angle, the incident angle of the signal source is less than the preset angle threshold, that is, the incident angle between the signal source and the rotated antenna array 12 is less than the preset angle threshold, so that the rotated antenna array 12 can better face the signal source to better receive the signal transmitted by the signal source.

[0041] In some embodiments, when the processor 30 determines that the incident angle of the signal source relative to the antenna array 12 is less than a preset angle threshold, for example, , it can be determined that the relative angle between the antenna array 12 and the signal source is small, and the processor 30 does not need to adjust the angle of the antenna array 12.

[0042] In some embodiments, the processor 30 may store multiple preset rotation angles for adjusting the rotation angle of the rotating base 20. In some embodiments, the multiple preset rotation angles may include, but are not limited to, -40°, -20°, 0°, 20°, and 40°. The preset rotation angles represent the rotation positions of the rotating base 20. For example, when the rotating base 20 is controlled to rotate 20°, the rotating base 20 rotates to drive the antenna array 12 on the housing 14 to rotate 20°. After rotation, the angle between the antenna array 12 and the display plane of the display 200 is 20°. When the processor 30 determines that the incident angle of the signal source relative to the antenna array 12 is greater than or equal to a preset angle threshold, the processor 30 controls the rotating base 20 to rotate to drive the antenna array 12 on the housing 14 to rotate to a preset rotation angle such that the adjusted incident angle of the signal source relative to the antenna array 12 is less than the preset angle threshold. In other embodiments, the preset rotation angle range may be ±100°, which can cover the display plane of the display 200. It is understood that the number of preset rotation angles can be greater and can be set according to actual needs, and this application is not limited thereto.

[0043] See also Figure 5 , Figure 5 This is a flow chart of a signal receiving method for a display provided in an embodiment of the present application. For example, Figure 5 The signal receiving method shown can be Figures 1 to 4 The signal receiver 100 of the display shown performs and includes the following steps.

[0044] Step S501: Initialize the signal receiver of the display.

[0045] In some embodiments, when the signal receiver 100 of the display is in an initialized state, the antenna array 12 may be arranged along the display plane of the display 200, that is, the receiving plane of the antenna array 12 may be coplanar or parallel to the display plane of the display 200. In some embodiments, after the signal receiver 100 is turned on and a communication connection is established with a signal source, such as a remote control, the signal receiver 100 receives signals transmitted by the signal source via the antenna array 12.

[0046] Step S502: Determine whether the current time and the time of the last control of the rotating seat to rotate are greater than or equal to a preset time threshold.

[0047] In some embodiments, the processor 30 can determine whether the time interval between the current time and the last time the rotatable base 20 was controlled to rotate is greater than or equal to a preset time threshold, that is, whether the time interval between the current time and the last time the rotatable base 20 angle was adjusted reaches the preset time threshold. If the time interval between the current time and the last time the rotatable base 20 was controlled to rotate is greater than or equal to the preset time threshold, a new round of signal detection is triggered and step S503 is executed. If the time interval between the current time and the last time the rotatable base 20 was controlled to rotate is less than the preset time threshold, the processor 30 returns to step S502 to continue executing, thereby avoiding frequent signal detection. It is understood that during the communication between the signal receiver 100 and the signal source, the signal source may change position multiple times, and the signal receiver 100 needs to adjust the rotation of the rotatable base 20 in real time according to the position change of the signal source. However, a new rotation of the rotatable base 20 is only executed when the time interval between the current time and the last time the rotatable base 20 was controlled is greater than or equal to the preset time threshold, thereby avoiding frequent rotation of the rotatable base 20.

[0048] In some embodiments, the preset time threshold may be, but is not limited to, 5 seconds, and may also be set to other values ​​according to actual needs, which is not limited in this application.

[0049] Step S503: Obtain the incident angle of the signal source relative to the antenna array according to the signal received by the antenna array.

[0050] In some embodiments, the signal receiver 100 may receive the signal transmitted by the signal source through the antenna array 12, and the processor 30 may obtain the incident angle of the signal source relative to the antenna array 12 based on the signal received by the antenna array 12. Figure 4 The relevant description will not be repeated here.

[0051] Step S504: performing outlier elimination and filtering smoothing processing on the acquired incident angle.

[0052] In some embodiments, after the processor 30 obtains the incident angle of the signal source relative to the antenna array 12 based on the signal received by the antenna array 12, it performs outlier removal and filtering and smoothing processing to prevent erroneous angle detection from causing erroneous control of the rotation of the rotating seat 20. Among them, the outlier removal of the incident angle can adopt the following comprehensive indicators: the variance of N consecutive measurement values ​​(N is a positive integer greater than or equal to 2), the difference between the measurement values ​​of two adjacent frames, if these indicators exceed the design threshold, it can be considered that the value of the incident angle obtained this time is an outlier. After performing outlier removal, Butterworth low-pass filtering is further performed to filter out high-frequency jitter errors in the measurement. Based on real-time considerations, Butterworth selects the 2nd order, which is specifically implemented as formula (2): Formula (2) in, 、 、 、 and The filter parameters used to perform Butterworth low-pass filtering can be calculated based on a 20 Hz sampling rate and a 2 Hz cutoff frequency, is the currently acquired incident angle, and are the incident angles obtained at the previous moment and the previous two moments respectively, is the incident angle after the latest filtering, and They are The first and second order delays of Figure 1 A coordinate system can be established between the receiving plane of the antenna array 12 and the display plane of the display 200, where the x-axis is along the length of the display plane of the display 200, the y-axis is along the width of the display plane of the display 200, and the z-axis is perpendicular to the display plane of the display 200. It can be understood that by performing outlier removal and filtering and smoothing processing, the error in the incident angle of the acquired signal source relative to the antenna array 12 can be reduced, thereby improving accuracy.

[0053] Step S505 , determining whether the incident angle of the signal source relative to the antenna array is greater than or equal to a preset angle threshold.

[0054] In some embodiments, when the processor 30 determines that the incident angle of the signal source relative to the antenna array 12 is greater than or equal to a preset angle threshold, it can be determined that the relative angle between the receiving plane of the antenna array 12 and the signal source is large, and the antenna array 12 needs to be adjusted to face the signal source. In some embodiments, the preset angle threshold can be, but is not limited to, 20 degrees. When the processor 30 determines that the incident angle of the signal source relative to the antenna array 12 is greater than or equal to the preset angle threshold, for example, , execute step S506; when the processor 30 determines that the incident angle of the signal source relative to the antenna array 12 is less than the preset angle threshold, for example, , it can be determined that the relative angle between the receiving plane of the antenna array 12 and the signal source is small, and there is no need to adjust the angle of the antenna array 12 , and the process returns to S502 .

[0055] Step S506: Control the rotating base to rotate to drive the antenna array on the housing to rotate until the incident angle is less than the angle threshold.

[0056] In some embodiments, when the processor 30 determines that the incident angle of the signal source relative to the antenna array 12 is greater than or equal to a preset angle threshold, the processor 30 controls the rotating base 20 to rotate to drive the antenna array 12 on the housing 14 to rotate until the incident angle of the signal source relative to the antenna array 12 is less than the angle threshold, so that the antenna array 12 is better oriented toward the signal source, thereby ensuring that a smaller relative angle can be obtained between the antenna array 12 and the signal source. In some embodiments, the angle of the antenna array 12 on the housing 14 driven by adjusting the rotating base 20 to rotate can be calculated by formula (1): Formula (1) in, θ t is the incident angle of the signal source. It is understood that after adjustment to this angle, the incident angle of the signal source is less than the preset angle threshold, that is, the incident angle between the signal source and the rotated antenna array 12 is less than the preset angle threshold, so that the rotated antenna array 12 can better face the signal source to better receive the signal transmitted by the signal source.

[0057] In some embodiments, the processor 30 may store multiple preset rotation angles for adjusting the rotation angle of the rotating base 20. In some embodiments, the multiple preset rotation angles may include, but are not limited to, -40°, -20°, 0°, 20°, and 40°. The preset rotation angles represent the rotation positions of the rotating base 20. For example, when the rotating base 20 is controlled to rotate 20°, the rotating base 20 rotates to drive the antenna array 12 on the housing 14 to rotate 20°. After rotation, the angle between the antenna array 12 and the display plane of the display 200 is 20°. When the processor 30 determines that the incident angle of the signal source relative to the antenna array 12 is greater than or equal to a preset angle threshold, the processor 30 controls the rotating base 20 to rotate to drive the antenna array 12 on the housing 14 to rotate to a preset rotation angle such that the adjusted incident angle of the signal source relative to the antenna array 12 is less than the preset angle threshold. In other embodiments, the preset rotation angle range may be ±100°, which can cover the display plane of the display 200. It is understood that the number of preset rotation angles can be greater and can be set according to actual needs, and this application is not limited thereto.

[0058] In some embodiments, when the processor 30 determines that the incident angle is greater than or equal to a preset angle threshold, the processor 30 determines a target angle and rotation direction based on the incident angle of the signal source relative to the antenna array 12. In some embodiments, the target angle is one of a plurality of preset rotation angles. The processor 30 controls the rotating base 20 to rotate in the rotation direction by the target angle, thereby driving the antenna array 12 to rotate until the incident angle of the signal source relative to the antenna array 12 is less than the angle threshold.

[0059] Step S507 : when the rotating base is controlled to rotate toward the target angle in the rotation direction, the determination of the incident angle of the signal source relative to the antenna array based on the signal received by the antenna array is stopped.

[0060] In some embodiments, when the processor 30 controls the rotating seat 20 to rotate to drive the antenna array 12 on the shell 14 to rotate until the incident angle is less than the angle threshold, the incident angle of the signal source relative to the antenna array 12 will change in real time, that is, the relative angle between the signal source and the receiving plane of the antenna array 12 will change in real time. Therefore, it is necessary to stop executing the determination of the incident angle of the signal source relative to the antenna array 12 based on the signal received by the antenna array 12, so as to avoid abnormalities or errors in obtaining the incident angle of the signal source.

[0061] It can be understood that step S506 and step S507 can be executed simultaneously.

[0062] Step S508 : Based on the rotated antenna array, the current rotation angle of the antenna array and the incident angle of the signal source relative to the antenna array are updated, and the position of the signal source to the display is updated according to the updated current rotation angle and incident angle.

[0063] In some embodiments, after the processor 30 controls the rotating base 20 to rotate to drive the antenna array 12 to rotate until the incident angle is less than the angle threshold, the current rotation angle of the antenna array 12 is updated, that is, the current angle between the receiving plane of the antenna array 12 and the display plane of the display 200. In some embodiments, the current rotation angle of the receiving plane of the antenna array 12 can be obtained by the rotating base 20. θ r In some embodiments, if the signal receiver 100 of the display is in the initial state, the receiving plane of the antenna array 12 may be coplanar or parallel to the display plane of the display 200, and the current angle of the receiving plane of the antenna array 12 may be θ r is 0°, if after the rotating base 20 is controlled to rotate to drive the antenna array 12 to rotate, the current rotation angle of the receiving plane of the antenna array 12 is θ r For other angle values.

[0064] In some embodiments, the processor 30 also updates the incident angle of the signal source relative to the rotated antenna array 12. After the antenna array 12 rotates to the target angle, the incident angle of the signal source relative to the rotated antenna array 12 also changes accordingly. Therefore, the updated incident angle of the signal source relative to the antenna array 12 needs to be determined by the processor 30. After the antenna array 12 rotates to the target angle, the incident angle of the signal source relative to the antenna array 12 is determined based on the rotated antenna array 12. It is necessary to solve the position and / or posture of the signal source based on the rotated antenna array 12. Therefore, a coordinate system transformation is introduced, that is, the rotation relationship from the antenna array 12 to the display plane of the display 200, so as to convert the relative relationship between the signal source and the rotated antenna array 12 into the relative relationship between the signal source and the display 200, thereby updating the position of the signal source to the display 200. Among them, the position of the signal source to the display 200 can be obtained by the rotation matrix, and the rotation matrix can be obtained by formula (3): Formula (3) Understandable, please refer to Figure 1 A coordinate system can be established between the receiving plane of the antenna array 12 and the display plane of the display 200, wherein the x-axis is the direction along the length of the display plane of the display 200, the y-axis is the direction along the width of the display plane of the display 200, and the z-axis is the direction perpendicular to the display plane of the display 200. θ r is the current rotation angle of the antenna array 12 relative to the display plane of the display 200.
