[0017] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0018] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0019] See also Figure 1 , Figure 1 The figure is a flow chart of a method for switching between horizontal and vertical screen display of a display device according to the first embodiment of the present invention. In the first embodiment of the present invention, the method for switching between horizontal and vertical screen display of a display device comprises steps S100-S300, wherein: S100, obtaining the usage status of the power interface, the sound signal picked up by the microphone array, and the strength of the signal received by the Wi-Fi module; S200, determining a placement form of the display device according to at least one of a usage state of the power interface, a sound signal picked up by the microphone array, and a strength of a signal received by the Wi-Fi module; S300: Switching the display mode of the display device according to the placement form of the display device.

[0020] See also Figure 2 , Figure 2 It is a structural schematic diagram of the display device of the present invention. In this embodiment, the display device has a shell, two power interfaces arranged on adjacent frames of the shell, a microphone array arranged in the shell, and a Wi-Fi module in the shell.

[0021] The display device can be a display, a smart doorbell with a screen, a tablet computer, a game console, a mobile phone, a TV, etc. The display device can be placed on a wall or a desktop for use, and a small display device can also be handheld for use.

[0022] The display device can be placed in a vertical position or a horizontal position.

[0023] When the power cord of the device is fixed, the different positions of the two power interfaces usually correspond to different placement forms of the display device. When it is detected that one of the power interfaces has power connected, it can be determined that the display device has been powered on. According to the different usage states of the two power interfaces, the placement form of the display device can be determined.

[0024] Of course, the present invention is not limited to only detecting the power-on status of the two power interfaces to determine the placement of the display device. The present invention also provides two other judgment methods, namely, using the sound signal picked up by the microphone array and the strength of the signal received by the Wi-Fi module to judge the placement of the display device.

[0025] When the display device is in different placements, the sound pickup effect of the microphone array will be different. Therefore, by analyzing the sound pickup beam data of the microphone array, the placement of the display device can also be determined.

[0026] In addition, the antenna directivity of the Wi-Fi module will also affect the strength of the received signal. Since the antenna of the Wi-Fi module is directional, and the position of the signal source generally does not change, the direction of the signal source also remains unchanged. When the display device switches to different placement forms, the antenna direction of the Wi-Fi module also switches, resulting in a mismatch between the antenna direction of the Wi-Fi module and the direction of the signal source, causing a difference in the strength of the signal received by the Wi-Fi module under horizontal and vertical screen placement. In other words, the strength of the signal received by different Wi-Fi modules corresponds to the different placement forms of the display device. Therefore, the placement form of the display device can also be determined based on the strength of the Wi-Fi signal received by the Wi-Fi module.

[0027] Finally, according to the result of any one of the above three determination methods, the placement of the display device can be determined, and the display mode of the display device can be switched accordingly. For example, when it is determined that the display device is placed in landscape orientation, the display mode can be automatically switched to landscape display; when it is determined that the display device is placed in portrait orientation, the display mode can be automatically switched to portrait display.

[0028] The present invention can more accurately determine the placement of the display device and realize automatic switching between horizontal and vertical screens by detecting the power interface, microphone array, wifi module and other hardware carried by the display device itself, combining the use status of the power interface, the sound signal picked up by the microphone array and the strength of the signal received by the Wi-Fi module and other judgment methods. This is not only conducive to the miniaturization of the device and improving the user experience, but also can reduce hardware costs and simplify the complexity of product design.

[0029] See also Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the use of the power interface in the horizontal screen display and vertical screen display modes of the display device provided in the second embodiment of the present invention. Figure 3 A schematic diagram of the flow chart of the second embodiment of the present invention. Figure 1 and Figure 2 In the second embodiment of the present invention, the step of determining the placement form of the display device according to at least one of the use state of the power interface, the sound signal picked up by the microphone array, and the strength of the signal received by the Wi-Fi module includes S210-S230, wherein: S210, detecting whether two power interfaces on adjacent frames are connected to power; S220: When a power supply is connected to the power interface on the frame in the length direction, the display device is placed in a horizontal position; S230: When a power source is connected to the power interface on the frame in the width direction, the placement of the display device is confirmed to be a vertical placement.

[0030] In this embodiment, the two power interfaces placed on adjacent frames of the shell can be arranged in such a way that, for example, one of the power interfaces is arranged on the frame in the length direction, and the other of the power interfaces is arranged on the frame in the width direction. According to the different usage states of the two power interfaces, the placement form of the display device can be determined. If the power interface on the frame in the length direction has power access, then it can be determined that the display device is placed in landscape orientation; if the power interface on the frame in the width direction has power access, then it can be determined that the display device is placed in portrait orientation. In this way, according to the usage states of the two power interfaces, and the corresponding relationship between the position of the power interfaces and the placement form of the display device, when the display device is powered on, it can be switched to landscape display or portrait display.

[0031] In this embodiment, taking a normal power supply device as an example, the power interface adopts a type-c interface. The power interface includes a first type-c interface 1 and a second type-c interface 2, wherein the first type-c interface 1 is arranged on a border in a width direction, and the second type-c interface 2 is arranged on a border in a length direction.

[0032] When the screen is used in portrait mode, the first type-c interface 1 is used for power supply. When the adapter communicates with the main control so that the main control recognizes that the first type-c interface 1 is used, the display mode of the display device is switched to portrait mode. When the screen is used in landscape mode, the second type-c interface 2 is used for power supply. When the adapter communicates with the main control so that the main control recognizes that the second type-c interface 2 is used, the display mode of the display device is switched to landscape mode. It can be understood that in some embodiments of the present invention, a power detection chip can also be provided to detect the power supply status of the power interface. Of course, in other embodiments of the present invention, a sampling detection circuit can also be provided on the power interface, and the voltage or current on the power interface is sampled and compared by the sampling detection circuit, and a power supply status signal is output to the main control module to determine the power supply status of the power interface.

[0033] See also Figure 6 , Figure 6 The method for switching between horizontal and vertical screen display of a display device provided in the third embodiment of the present invention is based on the above Figure 1 and Figure 2 In the third embodiment of the present invention, the step of determining the placement of the display device according to at least one of the use status of the power interface, the sound signal picked up by the microphone array, and the strength of the signal received by the Wi-Fi module includes S240, wherein: S240: Acquire the sound pickup beam data of each microphone, and determine the placement form of the display device according to the sound pickup beam data of each microphone.

[0034] See also Figure 4 and Figure 5 , since the relationship between the sound pickup beam data of each microphone can reflect the distance and angle relationship between the sound source and the microphone, and in the embodiment of the present invention, the user is generally looking directly at the display device, the approximate position of the sound source remains unchanged, and only the placement posture of the display device changes. The sound pickup beam data of each microphone has different rules under different placement postures of the display device. By comparing and analyzing the sound pickup beam data of the microphone obtained under different placement postures of the display device, the angle relationship between the sound source and the microphone can be obtained, thereby determining the placement posture of the display device.

[0035] See also Figures 4 to 9 In the fourth embodiment of the present invention, the steps of obtaining the sound pickup beam data of each microphone and determining the placement form of the display device according to the sound pickup beam data of each microphone include S241-S246, wherein: S241, a plurality of the microphones are arranged in sequence along the length border; S242, arranging the plurality of microphones into two symmetrical groups, and when the weighted parameters of the beam data of the two symmetrical microphones are similar, the placement of the display device is confirmed to be horizontal placement; S243: When the beamforming weighted parameter size of each microphone changes regularly corresponding to the arrangement order of the microphones, the display device is confirmed to be placed in portrait orientation, and the regular change is gradually increasing or gradually decreasing; or S244, the plurality of microphones are arranged in sequence along the width border; S245: When the beamforming weighted parameter size of each microphone changes regularly corresponding to the arrangement order of the microphones, the display device is confirmed to be placed in landscape orientation, and the regular change is gradually increasing or gradually decreasing; S246: Arrange the plurality of microphones into two symmetrical groups. When the weighted parameters of the beam data of the two symmetrical microphones are similar, the placement of the display device is confirmed to be a vertical screen placement.

[0036] In this embodiment, a microphone array system can be designed to collect the sound source of the device user. The system includes multiple microphones, and the microphones in the microphone array are arranged evenly along a straight line. When the user, that is, the sound source, makes a sound, the beam forming technology is used to accurately measure the beam data of the sound received by each microphone. By comparing and analyzing the weighted parameters of each microphone beam data, the physical placement state of the current device can be determined.

[0037] See also Fig.10 It can be understood that, assuming that the distance from the sound source S to the array coordinate center is r, and the spacing between any two adjacent arrays is d, the minimum value of the sound wave wavelength is , = T, is the speed of sound, T is the period, and the near-field and far-field models are as follows Fig.10 As shown: When r≤ When r> When , it is a far-field model.

[0038] In this application, since the distance between the sound source and the display device is relatively close, the beamforming adopts the near-field model. Specifically, the near-field model is as follows: the sound wave is regarded as a spherical wave, and the amplitude of the signal received by different microphones is significantly affected by the difference in the distance from the signal source to each microphone, and the difference in the wave path and amplitude from the signal source to different microphones is considered.

[0039] See also Figures 5 to 7 as well as Figure 8 In the present invention, the distances between the multiple microphones and the sound source are different due to the different arrangement orders of the multiple microphones.

[0040] The closer the distance between the microphone and the sound source is, the larger the beamforming weighted parameter corresponding to the microphone is; the farther the distance between the microphone and the sound source is, the smaller the beamforming weighted parameter corresponding to the microphone is.

[0041] It is understandable that in the present application, the placement of the display device is determined by the weighted parameters of each microphone beam data, which has nothing to do with the content of the sound emitted by the sound source, as long as the sound source can emit sound waves that can be monitored by the microphone array, for example, snapping fingers. In this way, the user does not need to shout out specific sentences or make specific sounds, but only needs to make a sound, and the display device can automatically switch to horizontal or vertical display.

[0042] It is understandable that when there are multiple sound sources in the environment, the sound source located directly in front of the display device can be identified through beamforming technology, and the sound signal of the sound source located directly in front of the display device can be screened out through voiceprint recognition technology, and the placement of the display device can be determined by the beam data of the sound signal. In this way, the failure of the method of determining the physical placement state of the current device by comparing and analyzing the weighted parameters of each microphone beam data due to interference from other sound sources can be avoided, thereby improving the reliability of the present invention.

[0043] It is understandable that the number of microphones in the microphone array can be set to an odd number or an even number. When the number of microphones in the microphone array is set to an odd number, the microphone located in the middle of the microphone array can be selected as the symmetry center, and the microphones on both sides of the symmetry center are divided into two symmetrical groups, and the two groups of microphones correspond one to one.

[0044] When the number of microphones in the microphone array is set to an even number, the middle position of the microphone array can be selected as the symmetry center, and the microphones on both sides of the symmetry center are divided into two symmetrical groups, and the two groups of microphones correspond to each other one by one.

[0045] Understandably, see Figure 2 When the number of the microphone arrays is set to two, as long as the two microphone arrays are set far enough apart, the placement of the display device can be determined by the method of the present invention.

[0046] See also Figures 4 to 6 In this embodiment, the microphone array includes four microphones A, B, C, and D.

[0047] When the plurality of microphones are arranged in sequence along the length border, taking a typical horizontal screen usage scenario as an example, see Figure 4 , group microphone A and microphone D into one group, group microphone B and microphone C into one group, where microphone A and microphone D are symmetrically arranged, and microphone B and microphone C are symmetrically arranged. If the beamforming weighting parameters of microphones B / C are basically the same and are greater than the weighting parameters of microphones A / D (that is, B≈C>A≈D), it indicates that the device is in landscape mode.

[0048] In a typical vertical screen usage scenario, the size of the beamforming weighting parameters of multiple microphones will change regularly with the distance between the microphone and the person. Figure 5 ,when Figure 4 The display device in the image is rotated 90° clockwise, that is, when the horizontal screen is switched to the vertical screen, the size of the beamforming weighting parameters of multiple microphones will gradually decrease with the distance between the microphone and the person, that is, D>C>B>A. Figure 6 ,when Figure 4 The display device in the image is rotated 90° counterclockwise, that is, when switching from horizontal screen placement to vertical screen placement, the size of the beamforming weighting parameters of multiple microphones will gradually decrease with the distance between the microphone and the person, that is, A>B>C>D.

[0049] Based on the same principle, when multiple microphones are arranged in sequence along the width border, taking a typical horizontal screen usage scenario as an example, the size of the beamforming weighting parameters of multiple microphones will change regularly with the distance between the microphone and the person. Figure 7 , the size of the beamforming weighting parameters of multiple microphones will gradually decrease with the distance between the microphone and the person, that is, D>C>B>A. Figure 7 When the display device in the image is rotated 180°, the sizes of the beamforming weighting parameters of multiple microphones will gradually decrease with the distance between the microphone and the person, that is, A>B>C>D.

[0050] See also Figure 8 , Figure 8 FIG. 5 is a flow chart of a fifth embodiment of the present invention. In this embodiment, the Wi-Fi module includes a first antenna 3 and a second antenna 4 that are vertically arranged.

[0051] The step of determining the placement form of the display device according to at least one of the use status of the power interface, the sound signal picked up by the microphone array, and the strength of the signal received by the Wi-Fi module includes S210-S230, wherein: S250, obtaining the strength of the Wi-Fi signal received by the first antenna 3 and the second antenna 4; S260: Compare the strength of the Wi-Fi signal received by the first antenna 3 and the strength of the Wi-Fi signal received by the second antenna 4 to determine the placement form of the display device.

[0052] In this embodiment, since the display device has a built-in Wi-Fi module, the display device can communicate with the router through the Wi-Fi module, and the router antenna is vertically polarized. In the horizontal screen usage scenario, the first antenna 3 is vertically polarized, and the second antenna 4 is horizontally polarized. Due to the polarization isolation phenomenon, the router Wi-Fi signal strength received by the first antenna 3 is significantly higher than that of the second antenna 4. Similarly, if the display device is placed in portrait mode at this time, the first antenna 3 is changed to horizontal polarization, and the second antenna 4 is changed to vertical polarization. The Wi-Fi signal strength received by the second antenna 4 is significantly higher than that of the first antenna 3. In this way, the physical placement status of the device can be determined.

[0053] See also Fig. 9 , Fig. 91 is a flow chart of the sixth embodiment of the present invention. In this embodiment, the step of determining the placement of the display device according to at least one of the use status of the power interface, the sound signal picked up by the microphone array, and the strength of the signal received by the Wi-Fi module includes S210-S230, wherein: S270: Control a corresponding one of the first antenna 3 and the second antenna 4 to operate according to the strength of the Wi-Fi signal received by the first antenna 3 and the strength of the Wi-Fi signal received by the second antenna 4.

[0054] In this embodiment, the Wi-Fi module includes a SPDT RF switch, which is a common type of RF switch, and its full name is Single Pole Double Throw. It includes an input end (usually called a P port) and two output ends (usually called T ports). The core function of the SPDT switch is to achieve signal path selection by switching the input signal to one of the two output ends.

[0055] The single radio frequency link of the display device at the receiving end is respectively connected to the first antenna 3 and the second antenna 4 through two T ports of the SPDT radio frequency switch. The display device can realize the seamless switching function of the first antenna 3 and the second antenna 4 through the SPDT radio frequency switch.

[0056] In this embodiment, in addition to determining the physical placement state of the device by the signal strength received by the first antenna 3 and the second antenna 4, thereby realizing the automatic horizontal and vertical screen switching function, the antenna working in the Wi-Fi module can also be seamlessly switched to the one with stronger signal strength, so that the display device can receive a stronger wireless signal, while taking into account the Wi-Fi signal strength indicators in both horizontal and vertical screen scenarios.

[0057] Specifically, in this embodiment, a main control module and a detection circuit can be set. The main control module obtains the strength of the received signals of the first antenna 3 and the second antenna 4 through the detection circuit and compares them, determines the antenna with the largest received signal strength, and sends a control signal to the SPDT RF switch to switch the signal transmission path to the antenna with the largest received signal strength.

[0058] It is understandable that, in the present invention, the Wi-Fi module may also use a single antenna, and the placement of the display device is determined by judging the signal strength of the single antenna.

[0059] Specifically, since the single antenna is directional and the position of the signal source generally does not change, the direction of the signal source also remains unchanged. When the display device switches to a different placement configuration, the antenna direction of the single antenna also switches, resulting in a mismatch between the antenna direction of the single antenna and the direction of the signal source, causing a difference in the strength of the signal received by the Wi-Fi module under horizontal and vertical screen placements. In other words, the strength of the signal received by different single antennas corresponds to the different placement configurations of the display device. Therefore, the placement configuration of the display device can also be determined based on the strength of the Wi-Fi signal received by the single antenna.

[0060] See also Fig.10 , Fig.10 2 is a flow chart of the seventh embodiment of the present invention. In this embodiment, the step of determining the placement of the display device according to at least one of the use status of the power interface, the sound signal picked up by the microphone array, and the strength of the signal received by the Wi-Fi module includes S280, wherein: S280, confirming the placement of the display device when at least two of the results of obtaining the placement of the display device through the power interface, obtaining the placement of the display device through the microphone array, and obtaining the placement of the display device through the Wi-Fi module are the same.

[0061] Since there are many possible states in which the user uses the display device, for example, the environment is too noisy and there are multiple sound sources, it is impossible to determine the placement state of the display device through the beamforming weighting parameters of the microphone. In this embodiment, the use state of the power interface can be detected first, and the placement form of the display device can be determined by the power-on state of the two power interfaces, and then the strength of the signal received by the first antenna 3 and the second antenna 4 can be detected to determine the placement form of the display device. The results of the two schemes are combined. When the two schemes determine that the placement form of the display device is the same, the placement form of the display device is finally confirmed to adapt to a variety of usage environments, prevent a single judgment method from making mistakes, and cause misjudgment, thereby improving the reliability of the present invention.

[0062] Since there are many possible states of the user using the display device, for example, in the absence of a wireless network, the user connects the display device to the Internet via a network cable or a set-top box. In this embodiment, the use state of the power interface can be detected first, and the placement of the display device can be determined by the power-on state of the two power interfaces, and then the sound signal picked up by the microphone array is detected to determine the placement of the display device. The results of the two schemes are combined. When the two schemes determine that the placement of the display device is the same, the placement of the display device is finally confirmed, which adapts to a variety of usage environments, prevents errors in a single judgment method, and causes misjudgment, thereby improving the reliability of the present invention.

[0063] In this embodiment, when the placement forms obtained by first detecting the use status of the power interface and then detecting the strength of the signal received by the first antenna 3 and the second antenna 4 are different; or when the placement forms obtained by first detecting the use status of the power interface and then detecting the sound signal picked up by the microphone array are different, the use status of the power interface can be detected first, and then the strength of the signal received by the first antenna 3 and the second antenna 4 can be detected, and finally the sound signal picked up by the microphone array can be detected, and the results of the three schemes can be combined. When at least two of the results of obtaining the placement form of the display device through the power interface, obtaining the placement form of the display device through the microphone array, and obtaining the placement form of the display device through the Wi-Fi module are the same, the placement form of the display device is confirmed and the final placement form is obtained to adapt to a variety of usage environments, prevent a single judgment method from making mistakes, and lead to misjudgment, thereby improving the reliability of the present invention.
