The second wireless signal is received and demodulated by the second communication interface 2202 in the wireless communication device 220, and the decoding module 2204 in the wireless communication device 220 decodes the demodulated signal to obtain feedback information, and sends it to the second communication interface 2102 in the display device 210 through the first communication interface 2201.

[0086] Optionally, the display device 210 may also send the control information and / or data to the wireless communication device 220 through the second communication interface 2102. The encoding module 2203 in the wireless communication device 220 encodes the control information and / or data, and then modulates it into a third wireless signal through the second communication interface 2202 and broadcasts it. After receiving the third wireless signal, the decoding module 2302 in the 3D glasses 230 decodes it, obtains the control information and / or data, and sends it to the control unit 2304 for corresponding processing.

[0087] It can be understood that in the above-mentioned wireless communication device 220 and / or 3D glasses 230, the signal encoding and decoding functions can be implemented by a digital processing module, the signal modulation and demodulation functions can be implemented by a wireless communication module (or a wireless communication interface), and the modulated wireless signal can be transmitted through an antenna. Among them, the digital processing module and the wireless communication module can be implemented by software, hardware, or a combination of software and hardware. Exemplarily, the digital processing module can be implemented by a digital processing circuit, and the wireless communication module (or a wireless communication interface) can be implemented by a wireless communication circuit or a wireless communication chip.

[0088] Above Figure 1The system architecture shown can also be applied to the application scenario of audio synchronization. In this scenario, the communication device 110 can be a playback device capable of playing audio, for example, the playback device can be a smart screen or a smart TV or a smart speaker or a projector, etc., or it can be a related component used to realize audio playback in a device such as a smart screen or a smart TV or a smart speaker, and the related component may include a hardware component or a software component or a hardware component and a software component. The electronic device 130 can be a speaker or other device capable of playing audio. Taking a smart screen and a speaker as an example, the synchronization information is used to synchronize the audio playback of the speaker with the audio playback of the smart screen. In one possible implementation, the synchronization information can be an audio clock signal, such as a periodic radio wave signal, more specifically, a square wave signal, a sine wave signal, a cosine wave signal, or a similar periodic signal, and the frequency and / or phase of the periodic signal are correlated with the frequency and / or phase of the audio clock signal in the smart screen (for example, the frequency and / or phase are the same, respectively). Correspondingly, the speaker can generate an audio clock signal synchronized with the smart screen based on the received periodic signal, and control audio playback based on the audio clock signal, thereby achieving audio synchronization. In another possible implementation, the synchronization information can be information used to achieve wireless communication clock synchronization between the smart screen and the speaker. For example, the synchronization information can be a time synchronization frame periodically sent by the smart screen. On the basis of keeping the wireless communication clock between the smart screen and the speaker synchronized, the smart screen device and the speaker can respectively generate an audio clock signal based on the wireless communication clock signal, thereby achieving synchronization of the audio clock signal and further achieving audio synchronization.

[0089] Above Figure 1The system architecture shown can also be applied to the application scenario of lighting effect synchronization. In an example of a lighting effect synchronization scenario, the communication device 110 may be a playback device capable of playing audio, for example, the playback device may be a smart screen or a smart TV or a smart speaker or a projector, etc., or may be a related component used to realize audio playback in a device such as a smart screen or a smart TV or a smart speaker, and the related component may include a hardware component or a software component or a hardware component and a software component. The electronic device 130 may be a lighting device, which may be an atmosphere light device, or a related component used to realize lighting effects on an electronic device. The synchronization information is used to control the light change of the lighting device to keep it synchronized with the rhythm of the audio played by the playback device. Taking a smart screen and an atmosphere light as an example, the smart screen can generate synchronization information according to the rhythm of the music played and send it to the atmosphere light in the above manner. The atmosphere light can control the light change according to the synchronization information, thereby achieving the effect of synchronizing the light change with the rhythm of the music. In another example of a lighting effect synchronization scenario, the communication device 110 may be a first lighting device, and the electronic device 130 may be a second lighting device. The synchronization information is used to control the lighting changes of the second lighting device to be synchronized with the lighting changes of the first lighting device, such as the lighting change frequencies of the first lighting device and the second lighting device to be synchronized.

[0090] Above Figure 1 The system architecture shown can also be applied to the application scenario of vibration synchronization. In one example of the vibration synchronization scenario, the communication device 110 can be a playback device capable of playing audio, for example, the playback device can be a smart screen or a smart TV or a smart speaker, etc., or it can be a related component used to realize audio playback in a device such as a smart screen or a smart TV or a smart speaker, and the related component can include a hardware component or a software component or a hardware component and a software component. The electronic device 130 can be a vibration device that can produce a vibration effect. The synchronization information is used to control the vibration of the vibration device to keep in sync with the rhythm of the audio played by the playback device. Taking the smart screen as an example, the smart screen can generate synchronization information according to the rhythm of the played music and send it to the vibration device in the above manner. The vibration device can control the frequency of the vibration according to the synchronization information, thereby achieving the effect of synchronizing the vibration frequency with the rhythm of the music. In another example of the vibration synchronization scenario, the communication device 110 can be a first vibration device, and the electronic device 130 can be a second vibration device, and the synchronization information is used to control the vibration frequency of the second vibration device to keep in sync with the vibration frequency of the first vibration device.

[0091] It is understood that the above is only an example of Figure 1The following are several application scenarios under the system architecture shown, and the embodiments of the present application do not limit the types of application scenarios. The following content mainly describes the 3D display application scenario as an example, and the implementation principles in other types of scenarios are similar to those in the 3D display scenario.

[0092] Since the present application involves active shutter 3D technology, in order to better understand the embodiments of the present application, the active shutter 3D technology is first described below.

[0093] Active shutter 3D technology mainly increases the refresh rate of the picture, divides the image frame into two, and forms two groups of pictures corresponding to the left eye and the right eye, called the left eye picture and the right eye picture. The two groups of pictures are displayed continuously and staggered, and the 3D synchronization (3D SYNC) signal is sent to the active shutter 3D glasses (hereinafter referred to as 3D glasses) through the signal transmitter to control the switch of the left eye LCD screen and the right eye LCD screen of the 3D glasses, so that the two groups of pictures enter the left and right eyes respectively. In other words, the left eye of the 3D glasses wearer can see the left eye picture at the right time, and the right eye can see the right eye picture at the right time, so as to use the visual persistence mechanism of the human eye, and the binocular parallax is generated after the superposition of the two eye images, and then the 3D stereo image is synthesized in the brain. The left eye LCD screen and the right eye LCD screen of the 3D glasses are white (i.e. transparent state) under normal circumstances, and the LCD screen becomes black (i.e. the transmittance decreases) when a certain voltage is applied.

[0094] See also Figure 4 , which illustrates the principle of active shutter 3D technology. As shown in the figure, when 3D image data (such as the original signal shown in the figure) is input to the display device, the display device processes the 120Hz image frame into two frames through frequency doubling. For example, the original image frame Rn corresponding to the right eye is frequency-doubled to generate image frame Rn 1 and Rn 2 , the original image frame Ln corresponding to the left eye is frequency-doubled to generate image frame Ln 1 and Ln 2 , the original image frame Rn+1 corresponding to the right eye is frequency-doubled to generate image frame Rn+1 1 and Rn+1 2 , and so on, the image frame Rn 2 , Ln 2 and Rn+1 2The screen is black or gray to reduce the crosstalk between the left and right eye images. The display device displays the left and right eye images alternately at a frequency of 120Hz, so that the left and right eye images are both 60Hz. At the same time, the display device transmits a 3D synchronization signal through a signal transmitter, and the 3D glasses control the switches of the left and right eye LCD screens according to the 3D synchronization signal. An example of a 3D synchronization signal is a square wave signal, whose high-level period corresponds to the left eye image, the left eye LCD screen of the 3D glasses is white (i.e., the on state) and the right eye LCD screen is black (i.e., the off state), and its low-level period corresponds to the right eye image, the right eye LCD screen of the 3D glasses is white and the left eye LCD screen is black.

[0095] In the 3D display application scenario, the embodiment of the present application not only supports the display device to transmit 3D synchronization information to the 3D glasses in one direction through the wireless communication device, but also the 3D glasses can send feedback information to the display device through the wireless communication device, thereby realizing two-way communication between the display device and the 3D glasses, forming a closed-loop system, thereby realizing an intelligent interactive experience.

[0096] Optionally, the feedback information may include one or more of the following information: status information of 3D glasses, position information of 3D eyes, eye tracking detection, sight direction information, user operation information, etc.

[0097] Exemplarily, the status information of the 3D glasses may include one or more of the following information: connection status information of the 3D glasses, battery power information of the 3D glasses, wearing status information of the 3D glasses, temperature information of the 3D glasses, and the like.

[0098] Several possible examples of intelligent interaction are given below based on different types of feedback information.

[0099] Example 1

[0100] The 3D glasses can send the detected connection status information to the display device via the wireless communication device, and the display device can perform corresponding processing according to the connection status information sent by the 3D glasses.

[0101] The connection status of the 3D glasses may include connection success, connection failure, etc. Further, the connection failure status may be further subdivided according to the cause of the connection failure. The 3D glasses may send the connection status information after establishing a communication connection with the wireless communication device, during the process of establishing a communication connection, or at other times.

[0102] The connection status information of the 3D glasses can be detected by a detection unit in the 3D glasses. The detection unit can be a software function module, and the software function module can obtain the current connection status by calling an application programming interface for querying the connection status.

[0103] Optionally, after obtaining the connection status, the 3D glasses can control the indicator light set on the 3D glasses to display according to the current connection status to prompt the current connection status. For example, if the current connection status is a successful connection, the indicator light can be controlled to display green light, and if the current connection status is a failed connection, the indicator light can be controlled to display red light.

[0104] Optionally, the 3D glasses can send the connection status information to the display device via a wireless communication device. After receiving the connection status information, the display device can display the connection status information on its display screen to visualize the connection status of the 3D glasses. For example, the display device can display a pop-up window in which the connection status of the 3D glasses is displayed, or display the connection status prompt information of the 3D glasses in a local area (such as the lower right corner area) of the display interface, such as prompt information in text form or prompt information in the form of a picture / icon, which is not limited in the embodiments of the present application.

[0105] Example 2

[0106] The 3D glasses can send the detected battery power information to the display device via the wireless communication device, and the display device can perform corresponding processing according to the battery power information sent by the 3D glasses.

[0107] The battery power information of the 3D glasses, for example, includes the percentage of power used or the percentage of remaining power. The 3D glasses can detect the battery power according to a set period and send the detected battery power information to the display device via a wireless communication device; or, when the battery power is lower than a set threshold, the battery power information is sent to the display device via a wireless communication device.

[0108] The battery power information of the 3D glasses can be detected by a detection unit in the 3D glasses. The detection unit can be a software function module, and the software function module can obtain the current battery power by calling an application programming interface for querying the battery power.

[0109] Optionally, the 3D glasses can send the detected battery power information to the display device via a wireless communication device. After receiving the battery power information, the display device can display the battery power information on its display screen to visualize the battery power of the 3D glasses. For example, the display device can display a pop-up window in which the battery power of the 3D glasses is displayed, or the battery power of the 3D glasses can be displayed in a local area of ​​the display interface (such as the lower right corner area). Alternatively, after receiving the battery power information, the display device can also determine whether the battery power of the 3D glasses is lower than a set threshold. If it is lower than the set threshold, the battery power information is displayed on the display screen, or a prompt message is displayed to indicate that the battery power is low.

[0110] In another possible implementation, the status information includes connection status information of the 3D glasses and battery power information of the 3D glasses. The 3D glasses can send the connection status information and battery power information to the display device via a wireless communication device. After receiving the connection status information and battery power information of the 3D glasses, the display device can display a pop-up window on its display screen, and display the connection status information and battery power information of the 3D glasses in the pop-up window.

[0111] In another possible implementation, the embodiment of the present application also supports actively querying the battery power of the 3D glasses through a menu bar displayed on the screen of the display device. Exemplarily, a menu bar may be displayed on the screen of the display device, and the menu bar may include an option to query the battery power of the 3D glasses. When the option is triggered, the display device may send a query request (or a query instruction) to query the battery power of the 3D glasses, and the query request is sent to the 3D glasses via a wireless communication device; the control unit in the 3D glasses can obtain the battery power information through the detection unit according to the query request, and send the battery power information to the display device via the wireless communication device.

[0112] There are multiple ways to trigger the option for querying the battery power of 3D glasses in the menu bar on the screen of the display device, for example, the embodiment of the present application can support voice mode or touch mode. In other embodiments of the present application, the 3D glasses can obtain the pointing and positioning information by means of eye tracking positioning detection ultra wide band (UWB) and the like, and send it to the display device through a wireless communication device. The display device determines that the option for querying the battery power of 3D glasses in the menu bar is selected according to the pointing and positioning information, and then sends a query request for querying the battery power of 3D glasses.

[0113] Example 3

[0114] The 3D glasses can send the detected wearing status information to the display device via the wireless communication device, and the display device can perform corresponding processing according to the wearing status information sent by the 3D glasses.

[0115] The wearing state of the 3D glasses may include wearing, taking off, etc. When the wearing state of the 3D glasses changes, such as when they are worn or taken off, the 3D glasses can detect the current wearing state and send the current wearing state information to the display device via the wireless communication device.

[0116] The wearing status information of the 3D glasses can be detected by a detection unit in the 3D glasses. The detection unit can be implemented by a sensor, for example, it can be implemented by one or one type of sensor, or by a combination of multiple or multiple types of sensors, and it may also be implemented by a sensor combined with software (i.e., sensor + functional module). Optionally, the sensor may include at least one or at least one of the following sensors: an optical sensor related to proximity detection (such as an infrared light sensor), a capacitive sensor, a Hall sensor (for example, it can detect the opening and closing state of the 3D glasses to identify the wearing state of the 3D glasses), etc.

[0117] In a possible implementation, the 3D glasses can send the information detected by the sensor to the display device via a wireless communication device. The display device can determine the wearing state of the 3D glasses according to the received feedback information.

[0118] In another possible implementation, when the detection unit is implemented by a sensor + a functional module, the functional module can determine the wearing status of the 3D glasses based on information detected by one or more sensors, and send the determined wearing status information to the display device via a wireless communication device.

[0119] After the display device receives the wearing status information of the 3D glasses, in a possible implementation, the display device may display the wearing status of the 3D glasses on its display screen, for example, by displaying the wearing status of the 3D glasses in a pop-up window.

[0120] After the display device receives the wearing status information of the 3D glasses, in another possible implementation, the display device can control the 3D video playback according to the wearing status of the 3D glasses. For example, if the received wearing status information indicates that the 3D glasses are taken off, the display device can immediately stop the 3D video playback, or switch from the 3D video mode to the 2D video mode; for another example, if the received wearing status information indicates that the 3D glasses are taken off, the display device can stop the 3D video playback after a set time, or switch from the 3D video mode to the 2D video mode. Compared with immediately stopping the 3D video playback or switching to the 2D video mode, by delaying the execution of the operation of stopping the 3D video playback or switching to the 2D video mode for a period of time, invalid control operations caused by the wearer taking off the 3D glasses for a short time can be avoided.

[0121] After the display device receives the wearing status information of the 3D glasses, in another possible implementation, the display device may send control information to the 3D glasses via a wireless communication device to control the 3D glasses to perform corresponding operations. For example, if the received wearing status information indicates that the 3D glasses are taken off, the display device may send control information to the 3D glasses via a wireless communication device to instruct the 3D glasses to shut down or enter a dormant state to save power consumption.

[0122] After the display device receives the wearing status information of the 3D glasses, in another possible implementation, the display device can count the wearing time of the 3D glasses. For example, after receiving the wearing status information indicating the "wearing" state, a timer can be started to count the wearing time. When the display device determines that the wearing time exceeds the set threshold, the display device can display health prompt information on its screen (such as prompting that the wearing time has timed out), and / or send control information to the 3D glasses through a wireless communication device to enable the 3D glasses to perform corresponding operations. For example, when the display device determines that the wearing time exceeds the set threshold and is currently in "children's mode", it can send control information to the 3D glasses through a wireless communication device to instruct the 3D glasses to shut down or enter a sleep state.

[0123] Optionally, after detecting the wearing state, the 3D glasses can perform corresponding operations according to the current wearing state. For example, if the current wearing state is "taken off", the 3D glasses can automatically shut down or enter a sleep state; for another example, if the current wearing state is "wearing", the 3D glasses can automatically turn on or end the sleep state.

[0124] It is understood that the various processing operations of the above display device after obtaining the wearing state can be combined with each other, and the embodiments of the present application do not limit this. For example, after obtaining the wearing state that the 3D glasses are "taken off", the display device stops playing the 3D video and sends a shutdown control message to the 3D glasses.

[0125] It is understood that the processing operations of the display device and the 3D glasses after obtaining the wearing status of the 3D glasses can be combined with each other, and the embodiments of the present application do not limit this. For example, when the 3D glasses detect the wearing status of "taken off", the wearing status information can be sent out and then shut down; the display device stops playing the 3D video after receiving the wearing status information.

[0126] Example 4

[0127] The 3D glasses can send the detected temperature information to the display device via the wireless communication device, and the display device can perform corresponding processing according to the temperature information sent by the 3D glasses.

[0128] The temperature information detected by the 3D glasses may include at least one of the following: the wearer's body temperature, the temperature of the 3D glasses (such as the temperature of the processing module or chip in the 3D glasses). The 3D glasses may perform temperature detection according to a set period and send the detected temperature information to the display device via a wireless communication device, or when the detected temperature exceeds a set threshold, send the detected temperature information to the display device via a wireless communication device.

[0129] The temperature information of the 3D glasses can be detected by a detection unit in the 3D glasses. The detection unit can be a temperature detection unit, such as a temperature sensor, or a negative temperature coefficient thermistor (NTC) separation device circuit, or a combination of the above devices.

[0130] After the display device receives the temperature information sent by the 3D glasses, in a possible implementation, the display device may display the temperature information on its display screen, or when the temperature indicated by the temperature information exceeds a set threshold, display a prompt message on its display screen to prompt that the temperature of the 3D glasses is too high.

[0131] After the display device receives the temperature information sent by the 3D glasses, in another possible implementation, the display device can determine whether the 3D glasses need to be protected from overheating based on the temperature indicated by the temperature information; if the 3D glasses need to be protected from overheating, control information can be sent to the 3D glasses via a wireless communication device to trigger the 3D glasses to perform overheating protection.

[0132] After the 3D glasses detect the temperature information, in another possible implementation, they can perform corresponding operations according to the current temperature. For example, if the current temperature exceeds a set threshold, the 3D glasses can automatically perform overheat protection.

[0133] It is understood that the various processing operations of the above display device after obtaining the wearing status can be combined with each other, and the embodiments of the present application do not limit this. For example, after obtaining the temperature of the 3D glasses, the display device displays a prompt message on its display screen and sends control information for overheat protection to the 3D glasses.

[0134] It is understood that the processing operations of the display device and the 3D glasses after obtaining the temperature of the 3D glasses can be combined with each other, and the embodiments of the present application do not limit this. For example, when the 3D glasses detect that the temperature is too high, overheat protection is performed and the temperature information is sent to the display device; after receiving the temperature information, the display device displays a prompt message on its display screen.

[0135] Example 5

[0136] The 3D glasses can send the user operation information detected by them to the display device via the wireless communication device, and the display device can perform corresponding processing according to the user operation information sent by the 3D glasses.

[0137] When the 3D glasses detect user operation information, they can send it to the display device via the wireless communication device.

[0138] Exemplarily, the user operation information may include one or more of the following:

[0139] - Video mode switching information, such as switching operation information from 3D video mode to 2D video mode, or switching operation information from 2D video mode to 3D video mode;

[0140] -Playback control operation information, which may include: stop playing, pause playing, adjust volume, mute with one key, etc.;

[0141] - Screenshot or screenshot operation information, for example, the operation information may include information related to operations such as starting and ending screen recording, screenshot, collection, and AI image recognition during movie watching;

[0142] - Screen on or screen off operation information;

[0143] -3D glasses power on or off information.

[0144] It can be understood that the above only lists several possible user operation information by way of example, and the embodiments of the present application do not limit the user operation type and the corresponding user operation information.

[0145] In the embodiments of the present application, the 3D glasses can detect user operation information in a variety of ways. Exemplarily, physical buttons can be set on the 3D glasses, and the user operation information can be obtained by detecting the user's operation on the physical buttons. For example, a video mode switching button is set on the 3D glasses, and by pressing the button, the 2D video mode and the 3D video mode can be switched. In another exemplary embodiment, a capacitive touch device can be set on the 3D glasses, and the capacitive touch device can obtain user operation information by detecting the user's touch operation. In another exemplary embodiment, sensors and other devices can be set on the 3D glasses to detect the user's tapping, sliding and other operations.

[0146] The user operation information can be detected by a detection unit in the 3D glasses. Based on the above user operation, the detection unit can be implemented by one or more devices such as physical buttons, micro switches, sensors, etc. For example, the sensor can include a touch sensor, a gravity sensor (g sensor), etc.

[0147] Optionally, after receiving the user operation information sent by the 3D glasses, the display device can perform corresponding processing according to the user operation information. For example, if the user operation information indicates switching from 3D video mode to 2D video mode, the display device switches from 3D video mode to 2D video mode; for another example, if the user operation information indicates stopping playback, the display device stops the current video playback.

[0148] Optionally, after detecting the user operation information, the 3D glasses may perform a corresponding operation according to the user operation information. For example, if the user operation information indicates that the 3D glasses are turned off, or switched from a 3D video mode to a 2D video mode, the 3D glasses perform a shutdown operation.

[0149] It can be understood that the various processing operations of the above-mentioned display device after obtaining user operation information can be combined with each other, and the embodiments of the present application are not limited to this.

[0150] It is understandable that the processing operations of the display device and the 3D glasses after obtaining the user operation information can be combined with each other, and the embodiments of the present application do not limit this. For example, when the 3D glasses detect that the 3D video mode is switched to the 2D video mode, the user operation information is sent to the display device and the 3D glasses are turned off; after the display device receives the user operation information, it switches from the 3D video mode to the 2D video mode.

[0151] Example 6

[0152] The 3D glasses can send the detected position information to the display device via the wireless communication device, and the display device can perform corresponding processing according to the position information sent by the 3D glasses.

[0153] The 3D glasses can send the detected position information to the display device via the wireless communication device when the position changes, or can perform position detection according to a set period and send the detected position information to the display device via the wireless communication device.

[0154] Optionally, the position information may include one or more of the following information: height information, distance from the screen of the display device, and horizontal position information. For example, when the wearer of 3D glasses squats or stands up, the height changes, and the height difference of the head when squatting and standing up can be detected by the 3D glasses. The above position information can be expressed as XYZ three-dimensional information, Figure 5 The XYZ three-dimensional information of the position of the 3D glasses is exemplarily shown, wherein X represents the distance between the position of the 3D glasses and the screen of the display device, Y represents the height of the position of the 3D glasses, and X represents the position of the 3D glasses in the horizontal direction.

[0155] Optionally, the 3D glasses can quantify the detected height information into corresponding posture information, and send the posture information to the display device via a wireless communication device. Exemplarily, the posture type may include squatting and standing. The correspondence between the height and the posture type may be preset, and the 3D glasses may determine the posture type corresponding to the height according to the correspondence after detecting the height information.

[0156] The position information of the 3D glasses can be detected by a detection unit inside the 3D glasses. The detection unit can be a sensor for detecting the position. The sensor can obtain the position information by one of the following distance measurement methods or a combination of multiple distance measurement methods: laser distance measurement method, time of flight (TOF) distance measurement method, ultrasonic distance measurement method, A+G distance measurement method, infrared distance measurement method, etc. Accordingly, the detection unit can be implemented by one or more sensors, or by one or more sensors, for example, it can include a laser distance measurement sensor, an ultrasonic distance measurement sensor, an infrared distance measurement sensor, etc.

[0157] For example, taking the laser ranging method as an example, the laser ranging sensor can send a laser signal to the ground and receive a signal returned from the ground. According to the time difference between signal sending and receiving, the height of the 3D glasses from the ground can be measured.

[0158] Optionally, after receiving the position information sent by the 3D glasses, the display device can display the 3D video screen according to the position information, so that the displayed 3D video screen matches the position. Exemplarily, the processor in the display device (or the 3D video application running in the processor, such as a virtual reality application) generates a screen matching the position according to the position information, and sends the screen for display, so that the user can watch the screen adjusted according to the position through the 3D glasses. For example, when it is determined according to the position information of the 3D glasses that the wearer approaches the screen, the visible range of the screen can be reduced to produce a viewing experience in which the screen is pulled closer. When it is determined according to the position information of the 3D glasses that the wearer is away from the screen, the visible range of the screen can be increased to produce a viewing experience in which the screen is pulled farther away; for another example, when it is determined according to the position information of the 3D glasses that the wearer squats, the viewing angle of the screen can be reduced to produce a viewing experience of looking straight or looking up. When it is determined according to the position information of the 3D glasses that the wearer stands up, the viewing angle of the screen can be increased to produce a viewing experience of looking down. For another example, when it is determined based on the position information of the 3D glasses that the wearer has moved to the left, the picture angle of view can be changed and / or the picture can be shifted to display more content on the left; when it is determined based on the position information of the 3D glasses that the wearer has moved to the right, the picture angle of view can be changed and / or the picture can be shifted to display more content on the right, thereby achieving a viewing experience in which the picture moves with the person.

[0159] For example, taking height information as an example, Figure 6 As shown in FIG. 1 , when the user is standing, an object in the image viewed through the 3D glasses is as follows: Figure 6 As shown in Figure (a) in FIG. 1 , when the user squats, the display device can adjust the image according to the height change of the user's head, so that the object viewed by the user through the 3D glasses is as follows: Figure 6 As shown in Figure (b).

[0160] Based on the above implementation, when the user's posture changes (for example, from squatting to standing, or from standing to squatting), the 3D picture can change accordingly according to the change of the user's posture, thereby improving the user's viewing experience.

[0161] Furthermore, when only height information is detected, the 3D picture only changes with the change of height, and there is no need to process the picture using deformation algorithm and head tracking algorithm. Therefore, the picture processing delay is low, and the processing overhead and resource requirements are also low, thereby reducing the risk of lag and improving the user's viewing experience.

[0162] The above are only several possible position detection methods, and the embodiments of the present application do not limit this. For example, in another possible implementation, multiple signal transmitters (called reference points) can be set in the room, and the positions of these reference points are known to the 3D glasses or the display device. The 3D glasses and the reference points can send signals to each other, and the 3D glasses can be positioned based on the TOF method.

[0163] Example 7

[0164] The 3D glasses can send the detected position information to the display device via a wireless communication device. The display device can determine the wearer's movement posture based on the position information sent by the 3D glasses and the image taken by the camera of the display device, and perform corresponding processing based on the wearer's movement posture.

[0165] The specific implementation of the 3D glasses performing position detection and sending the position information to the display device may refer to the above examples.

[0166] After receiving the position information from the 3D glasses, the display device can determine the motion posture of the 3D glasses wearer in combination with the image captured by the display device's camera, such as an artificial intelligence (AI) camera, and perform corresponding processing according to the motion posture of the 3D glasses wearer. For example, the image can be calibrated, or a prompt can be given when the posture is determined to be incorrect.

[0167] Taking a 3D game scene as an example, 3D glasses can send the position information of the wearer of the 3D glasses to the display device through a transceiver before the game starts. The display device can automatically calibrate according to the position information to ensure that the picture matches the height of the wearer of the 3D glasses. During the game, the 3D glasses can continuously send their position information to the display device. The display device can accurately determine the movement posture of the wearer of the 3D glasses in combination with the images collected by its AI camera, so that the picture can be displayed according to the movement posture of the wearer, thereby improving the user experience. For example, if the display device determines that the wearer is close to the screen based on the position information of the wearer of the 3D glasses, and determines that the wearer is currently sitting based on the images collected by the AI ​​camera, the visible range of the picture can be reduced and the angle of view can be adjusted to adapt to the wearer's current position and posture.

[0168] Optionally, when the display device determines that the movement posture (such as sitting posture) of the wearer of the 3D glasses is incorrect, it can also give corresponding prompts, such as displaying the prompt information on the screen or making a voice broadcast.

[0169] Example 8

[0170] The 3D glasses can perform position detection and eye tracking detection, obtain the position information of the 3D glasses and the eye tracking information, and send the position information and the eye tracking information to the display device through a wireless communication device. The display device can perform corresponding processing based on the position information and the eye tracking information sent by the 3D glasses.

[0171] The specific implementation of the 3D glasses performing position detection and sending the position information to the display device may refer to the above examples.

[0172] The position information and eye tracking detection of the 3D glasses can be detected by a detection unit in the 3D glasses. Optionally, the detection unit may include a position detection unit and an eye tracking detection unit. The specific implementation of the position detection unit may refer to the aforementioned embodiment. The eye tracking detection unit may be used to detect the eye movement of the left eye and / or the right eye. Optionally, the eye tracking detection unit may include one or more of the following devices: an infrared sensor, a camera.

[0173] For example, Figure 7 3D glasses with position detection and eye tracking detection functions are shown. Figure 7As shown, a position detection unit 701 is provided in the middle of the two lenses of the 3D glasses. For example, the position detection unit can be an infrared distance sensor, which can respectively transmit infrared signals to at least one of the directions of the front (toward the screen of the display device), the bottom (toward the ground), and the side (toward the wall), receive the returned infrared signals, and determine the distances in the above directions according to the time difference between sending and receiving, thereby obtaining the position information. A first eye tracking detection unit 702 and a second eye tracking detection unit 703 are respectively provided around the two lens positions of the 3D glasses, which are used to detect the eye movements of the left eye and the right eye, respectively. The first eye tracking detection unit 702 and the second eye tracking detection unit 703 can be implemented by infrared sensors and / or cameras.

[0174] The 3D glasses can send the information detected by the position detection unit 701, and the information detected by the first eye tracking detection unit 702 and the second eye tracking detection unit 703 to the display device through a wireless communication device. The display device can determine the position information of the 3D glasses based on the information detected by the position detection unit 701, determine the eye tracking information of the wearer of the 3D glasses based on the feedback information of the first eye tracking detection unit 702 and the second eye tracking detection unit 703, and determine the landing point of the wearer's line of sight in the picture.

[0175] After the display device obtains the point of sight of the 3D glasses wearer in the picture, in a possible implementation, the display device can display the 3D picture according to the movement trajectory of the point of sight to achieve the effect of "picture follows eye movement".

[0176] After the display device obtains the point of sight of the 3D glasses wearer in the picture, in another possible implementation, the display device can trigger the menu function or menu option of the corresponding area according to the point of sight, so that the menu function displayed on the screen of the display device can be selected or controlled by pointing with the human eye.

[0177] In a possible implementation, after the display device obtains the position information from the 3D glasses, it can display the 3D picture according to the position information, so that the 3D picture matches the position of the wearer of the 3D glasses. For example, when the wearer walks away from or approaches the screen of the display device, the display device can adjust the visible range of the 3D picture (for example, when walking closer to the screen, the visible range can be reduced, and when walking away, the visible range can be increased). In this case, the display device can first determine the visible range according to the position information, and then determine the landing point position within the visible range according to the eye tracking information.

[0178] Example 9

[0179] The 3D glasses cooperate with the display device to detect the line of sight direction and send the line of sight direction information to the display device through the wireless communication device. The display device can perform corresponding processing according to the line of sight direction information sent by the 3D glasses.

[0180] In an embodiment of the present application, the gaze direction information can be used to indicate the head movement of the 3D glasses wearer. For example, the gaze direction information can be obtained by detecting the head rotation of the 3D glasses wearer and the position information of the 3D glasses (such as the distance from the screen of the display device and / or the height of the 3D glasses).

[0181] The sight direction information can be detected by a detection unit in the 3D glasses. Optionally, the detection unit can include at least two direction positioning detection units, which can be arranged around the frame of the 3D glasses, such as on the left and right sides of the frame to detect left and right rotation of the head, or on the upper and lower sides of the frame to detect up and down rotation of the head (such as raising or lowering the head).

[0182] like Figure 8 As shown, taking the detection of left and right head rotation by two pointing positioning modules as an example, the two pointing positioning detection units are respectively the first pointing positioning detection unit 801 and the second pointing positioning detection unit 802. The first pointing positioning detection unit 801 and the second pointing positioning detection unit 802 are respectively located on both sides of the 3D glasses, and can send positioning signals to the display device and receive positioning signals sent by the pointing positioning detection unit 803 in the display device, and determine the distance between the pointing positioning detection unit and the screen of the display device according to the time difference between sending and receiving positioning signals. When the head of the wearer of the 3D glasses turns left or right, there will be a difference in the distance detected by the first pointing positioning detection unit 801 and the second pointing positioning detection unit 802. According to the distance difference and the distance between the 3D glasses and the display device, the rotation angle can be calculated, and the angle of sight change can be determined according to the rotation angle.

[0183] In one possible implementation, the 3D glasses can send the determined distance difference or the calculated rotation angle to the display device via a wireless communication device. In another possible implementation, the pointing positioning detection unit 83 in the display device can determine the distance difference between itself and the first pointing positioning detection unit 801 and the second pointing positioning detection unit 802 according to the time difference between receiving and sending positioning signals, and the rotation angle can be calculated according to the distance difference and the distance between the 3D glasses and the display device, and the line of sight change angle can be determined according to the rotation angle, so that there is no need for the 3D glasses to send feedback information to the display device.

[0184] Optionally, the pointing and positioning detection unit in the 3D glasses and the display device can be implemented using a pointing and positioning detection unit based on ultrawide band (UWB) technology, thereby achieving sub-centimeter-level spatial accuracy and millisecond-level temporal accuracy.

[0185] After the display device obtains the gaze direction information, in a possible implementation, the display device can display a 3D image according to the gaze direction information to achieve an effect of "the image moves with the head".

[0186] After the display device obtains the gaze direction information, in another possible implementation, the display device can determine the landing point of the gaze on the screen based on the gaze direction information, and trigger the menu function or menu option of the corresponding area based on the landing point, thereby realizing the selection or control of the menu function displayed on the screen of the display device through head movements.

[0187] In the above examples, the information transmission method between the 3D glasses and the display device can be referred to the relevant content in the previous text, which will not be repeated here.

[0188] The multiple methods described in Examples 1 to 9 above may also be used in combination to achieve more intelligent interactive functions.

[0189] In one possible implementation, the intelligent interaction functions provided in the above examples seven and nine can be used in combination. That is, the detection unit in the 3D glasses can detect the position information and the line of sight direction information, and send the position information and the line of sight direction information to the display device through the wireless communication device, so that the display device performs corresponding processing. For specific implementation methods, please refer to the relevant content in the above examples seven and nine. This implementation method can realize accurate height, relative position, action and posture detection. In scenarios such as 3D games and somatosensory games, higher precision detection can be achieved, and more complex game action interactions can be completed, thereby improving user experience.

[0190] In another possible implementation, the intelligent interactive functions provided in the above examples 7, 8 and 9 can be used in combination. That is, the detection unit in the 3D glasses can detect the position information, eye tracking information and sight line information, and send the position information, eye tracking information and sight line information to the display device through a wireless communication device, so that the display device performs corresponding processing. For specific implementation methods, please refer to the relevant content in the above examples 7, 8 and 9. This implementation method can realize the detection of multiple dimensions such as XYZ space three-dimensional detection, head movement detection and eye sight tracking detection. According to the detection of these dimensions, the experience of 3D augmented reality (AR) / virtual reality (VR) games can be realized on the display device. The display screen can be adjusted in real time with a sense of space after multiple dimensional data judgments such as the user's height, body position / body walking trajectory, head position / head movement trajectory, eye position / eye visual trajectory, etc., thereby improving the user experience.

[0191] based on Figure 1 In the communication system shown, in order to support two-way communication between the communication device 110 and the electronic device 130, in some embodiments of the present application, a first communication interface and a second communication interface are provided on the communication device 110, the first communication interface can send synchronization information, and the second communication interface can receive feedback information from the electronic device 130.

[0192] In addition, in the related technology under the 3D display application scenario, a dedicated interface (3D SYNC interface) is set on the display device for outputting a 3D synchronization signal. A signal transmitter can be connected to the dedicated interface through a cable, so that the signal transmitter can convert the 3D synchronization signal output by the dedicated interface into an infrared signal or a Bluetooth signal for transmission. An example of a 3D SYNC interface can be as follows: Fig. 9 As shown, the 3DSYNC interface includes 3 pins, pin#1 is a 5V DC power supply (+5Volt DC power out) pin, which can provide power for the signal transmitter, pin#2 is a ground pin, and pin#3 is a 3D SYNC signal output pin.

[0193] A 3D SYNC interface is specially provided on the display device to output a 3D synchronization signal, which results in a waste of control circuit space of the display device and increases the production cost of the display device. In addition, the 3D SYNC interface only supports one-way transmission.

[0194] Furthermore, to solve the above-mentioned problem, in some embodiments of the present application, there is no need to set a dedicated interface for outputting 3D synchronization information on the display device. Instead, the display device can be connected to a wireless communication device through a normalized universal interface, and the 3D synchronization information can be output to the wireless communication device, which can be converted into a wireless signal and transmitted through the wireless communication device to control the 3D glasses.

[0195] The following takes a 3D display scene as an example and describes in detail the structure of the relevant device in the embodiment of the present application in combination with the accompanying drawings.

[0196] See also Figure 2 In the 3D display application scenario shown, the first communication interface 2101 and the second communication interface 2102 in the display device 210 are of the same type of communication interface and support the same communication protocol. The first communication interface 2101 and the second communication interface 2102 match the first communication interface 2201 in the wireless communication device 220 in structure, and the first communication interface 2101 and the second communication interface 2102 can be connected to the first communication interface 2201 through a cable, or can be directly connected to save cable costs.

[0197] In a possible implementation, the first communication interface 2101 and the second communication interface 2102 in the display device 210 may be some pins in a normalized universal communication interface provided on the display device 210. By reusing the normalized universal communication interface on the display device to connect to the wireless communication device 220 to output 3D synchronization information, compared with using a dedicated interface to transmit 3D synchronization information, communication interfaces can be saved, which is beneficial to the spatial stacking and normalized design of the display device and can reduce costs.

[0198] Exemplarily, the universal communication interface may be a universal serial bus (USB) interface, such as a USB Type-A interface, a USB Type-B interface, a USB Type-C interface, or an evolved USB interface, which is not limited in the embodiments of the present application. Accordingly, the first communication interface 2201 in the wireless communication device 220 is a USB interface that matches the USB interface on the display device 210. Optionally, the USB interface on the display device 210 may be a female connector, and the USB interface on the wireless communication device 220 may be a male connector, so that the wireless communication device 220 may be directly plugged into the display device 210.

[0199] As another example, the universal communication interface on the display device 210 and the first communication interface 2201 on the wireless communication device 220 may be a network interface, such as an Ethernet interface, so that the wireless communication device 220 may be connected to the display device 210 via a network cable.

[0200] Taking the interface between the display device and the wireless communication device as a USB Type-C interface as an example, Fig.10 A schematic diagram of pins in a USB Type-C socket (female connector) is shown. The USB Type-C socket includes 2 rows of 24 pins, one row of which is labeled A1 to A12, and the other row of which is labeled B1 to B12. Each pin corresponds to a corresponding lane. The 24 pins are:

[0201] 4 power pins V BUS , as shown in the figure A4, A9, B4, B9;

[0202] 4 ground pins GND, as shown in the figure A1, A12, B1, B12;

[0203] Two pairs of 4 pins D+ / D- for USB2 data transmission, as shown in the figure A6, A7, B6, B7. Each pair of D+ / D- corresponds to a data channel, and D+ and D- are used to transmit a pair of differential signals;

[0204] Four pairs of 8 pins TXx+ / TXx- for USB3 data transmission and display data (DP) data transmission, as shown in the figure A2, A3, A10, A11, B2, B3, B10, B11. Each pair of TXx+ / TXx- corresponds to a data channel, and TX+ and TX- are used to transmit a pair of differential signals. Among them, USB3 data transmission and DP data transmission share the same 4 pairs of pins;

[0205] 2 configuration channel (CC) pins (CC1 and CC2), as shown in the figure A5, B5. CC pins (or CC channels) are used to confirm the transmission direction and forward and reverse insertion during the USB Type-C connection process, as well as to transmit USB PD BCM code signals to implement load function configuration;

[0206] 2 USB Type-C extension pins (SBU1 and SBU2), A8 and B8 as shown in the figure. SBU1 and SBU2 are transmission channels for auxiliary signals and have different uses in different application scenarios.

[0207] based on Fig.10In the USB Type-C interface shown in the embodiment of the present application, the first communication interface 2101 in the display device 210 can be implemented by an idle pin in the USB Type-C interface, for example, the idle pin can be an isolated ground (GND) pin for transmitting USB differential signals (such as differential signals D+ / D-, or differential signals TX1+ / TX1-). The second communication interface 2102 in the display device 210 can be implemented by a pin in the USB Type-C interface for implementing a bidirectional data transmission function, such as the pin D+ / D- corresponding to the USB2 data transmission channel in the USB Type-C interface (for example, Fig.10 A6, A7, B6, B7 in the USB Type-C interface) to implement bidirectional data transmission based on the USB2 protocol; for example, the pins TX1+ / TX1- corresponding to the USB3 data transmission channel in the USB Type-C interface (for example, Fig.10 A2, A3, A10, A11, B2, B3, B10, B11) are used to realize bidirectional data transmission function based on USB3 protocol.

[0208] In order to achieve the above Figure 1 , Figure 2 or Figure 3 The functions of each device in the system architecture shown in the figure, the embodiment of the present application provides a possible structure of a communication device (such as a display device), a wireless communication device and an electronic device (such as 3D glasses). The following takes the display device, wireless communication device and 3D glasses in the 3D display scene provided by the embodiment of the present application as an example, and describes the structure of the relevant device in combination with the accompanying drawings.

[0209] See also Fig.11 , is a structural schematic diagram of a display device provided in an embodiment of the present application.

[0210] like Fig.11 As shown, the display device 1100 includes a processor 1110, a switch 1120, a first communication interface 1131, and a second communication interface 1132. Further, a power supply module 1140 may be included. It is understood that the display device 1100 may also include more modules, which is not limited in the embodiment of the present application.

[0211] The processor 1110 is provided with a first interface, and the first interface is used to output 3D synchronization information (3D SYNC). The first interface is connected to the second connection point in the switch 1120. When the switch 1120 connects the second connection point and the first connection point under the control of the processor 1110, the 3D synchronization information output by the first interface of the processor 1110 can be sent to the wireless communication device connected to the display device 1100 through the first communication interface 1131.

[0212] Optionally, the first communication interface 1131 and the second communication interface 1132 may be implemented by at least one pin in a universal communication interface (such as a USB interface) provided on the display device 1100. Taking the USB interface as an example, the first connection point in the switch 1120 may be connected to an idle pin in the USB interface, that is, the 3D synchronization information may be sent through the idle pin in the USB interface.

[0213] Optionally, the processor 1110 is further provided with a second interface, which is connected to the second communication interface 1132. The second interface has a bidirectional transmission function, and the feedback information from the 3D glasses can be transmitted to the processor 1110 through the second communication interface 1132 and the second interface. Further, the control information sent by the processor 1110 to the 3D glasses can be sent to the wireless communication device connected to the display device 1100 through the second interface and the second communication interface 1132. The second interface may include one or more pins, which are connected to one or more pins in the second communication interface 1132 (excluding the pin connected to the switch 1120).

[0214] The above-mentioned second interface can be a physical layer interface (referred to as the physical interface for short), which is used to perform physical layer signal conversion, that is, the data or control information to be sent can be converted (or processed) into a physical layer signal and sent to the second communication interface 1132, or the physical layer signal from the second communication interface 1132 can be converted (or processed) into data that can be processed by the upper-layer data processing unit.

[0215] Optionally, the processor 1110 may also be provided with a third interface, and the processor 1110 may output a control instruction to the switch 1120 through the third interface, so as to control the switch 1120 to connect the first interface with the first communication interface 1131, such as connecting the second connection point and the first connection point in the switch 1120. Exemplarily, the third interface may be a general-purpose input / output (GPIO) interface on the processor 1110.

[0216] Optionally, the switch 1120 further includes a third connection point, which is used for grounding (GND), or according to the communication protocol, the third connection point can be connected to a related pin on the processor 1110. Optionally, by default, the switch 1120 connects the connection between the third connection point and the first connection point, and after receiving a control instruction output by the processor 1110 for connecting the 3D synchronization information output path, the connection is switched, that is, the connection between the third connection point and the first connection point is disconnected and the connection between the second connection point and the first connection point is connected.

[0217] Optionally, at least one of the processor 1110 , the switch 1120 , the first communication interface 1131 , and the second communication interface 1132 may be powered by the power supply module 1140 .

[0218] Optionally, the second communication interface 1132 can also serve as a power supply terminal to supply power to a wireless communication device connected to the interface. Accordingly, the second communication interface 1132 can include a pin for power supply, and the power supply module 1140 can supply power to the pin, thereby supplying power to the external wireless communication device.

[0219] Based on the above Fig.11 In one possible implementation, the processor 1110 may be a main processor, such as a central processing unit (CPU).

[0220] Based on the above Fig.11 In one possible implementation, the switch 1120 may be as follows: Fig.11 The single pole double throw (SPDT) switch shown may also be an analog switch or a discrete switch, etc., which is not limited in the present embodiment. It is understood that Fig.11 The structure of the switch shown is only a schematic diagram of its logical functional structure and does not limit its physical structure.

[0221] based on Fig.11 The structure of the display device shown, Fig.12 Taking the first communication interface 1131 and the second communication interface 1132 as an example, the structure of the display device is described. A possible structure of the USB Type-C interface can be referred to as Fig.10 .

[0222] like Fig.12 As shown, the switch 1120 can connect the 3D SYNC interface on the processor 1110 to the first pin in the USB Type-C interface 1130 for transmitting 3D synchronization information. For example, the first pin can be an isolated ground (GND) pin for transmitting USB differential signals (such as differential signals D+ / D-, or differential signals TX1+ / TX1-). Other pins in the USB Type-C interface 1130 can be connected to the USB physical interface (USB PHY) integrated on the processor 1110. For example, the USB PHY connects the pins D+ / D- corresponding to the USB2 data transmission channel in the USB Type-C interface 1130 (for example, Figure 6A6, A7, B6, B7 in the USB Type-C interface 1130) is used to implement a bidirectional data transmission function based on the USB2 protocol; for example, the USB PHY is connected to the pins TX1+ / TX1- corresponding to the USB3 data transmission channel in the USB Type-C interface 1130 (for example, Figure 6 A2, A3, A10, A11, B2, B3, B10, B11) in the USB Type-C interface 1130 are used to implement a bidirectional data transmission function based on the USB3 protocol. In addition, the power supply module 1140 can be the power pin V in the USB Type-C interface 1130. BUS powered by.

[0223] Among them, the USB PHY is used to perform physical layer electrical signal conversion, for example, receiving the differential signal D+ / D- from the USB Type-C interface 1130, decoding the differential signal so as to provide the decoded data to the USB controller integrated in the processor 1110 for processing; for another example, encoding the data from the USB controller to obtain the differential signal D+ / D-, and outputting the differential signal to the corresponding pins in the USB Type-C interface 1130.

[0224] Optionally, if the processor 1110 (or the USB controller in the processor 1110) does not have an integrated USB PHY, but is connected to the USB Type-C interface 1130 through an external USB PHY, then other pins in the USB Type-C interface 1130 except for the pins used to transmit 3D synchronization information can be connected to corresponding pins of the external USB PHY.

[0225] The USB Type-C interface 1130 can be a USB Type-C socket (i.e., the female head of the USB interface), and accordingly, the first communication interface of the wireless communication device can be a USB Type-C plug (i.e., the male head of the USB interface). In this way, direct connection through the USB male and female heads can save external cables, reduce costs, and make the overall effect simple and beautiful.

[0226] See also Fig.13 , is a schematic diagram of the structure of a wireless communication device provided in an embodiment of the present application.

[0227] like Fig.13 As shown, the wireless communication device 1300 includes a first communication interface 1301, a digital processing module 1310, and a second communication interface 1302. Optionally, the second communication interface 1302 may include a wireless communication module 1320 and an antenna.

[0228] The first communication interface 1301 is used to connect to a display device, and can receive 3D synchronization information from the display device and send feedback information to the display device. The digital processing module 1310 can encode the 3D synchronization information. The second communication interface 1302 can modulate the encoded 3D synchronization information into a first wireless signal and send the first wireless signal, and receive and demodulate the second wireless signal from the 3D glasses. The digital processing module 1310 can also decode the information obtained after demodulation to obtain feedback information sent by the 3D glasses.

[0229] Optionally, the first communication interface 1301 may also receive control information from the display device, the digital processing module 1310 encodes the control information, and the second communication interface 1302 modulates the encoded control information into a third wireless signal and sends the third wireless signal.

[0230] Taking the first communication interface 1301 as a USB Type-C interface as an example, corresponding to the pin for transmitting 3D synchronization information in the USB Type-C interface of the display device, the matching pin in the first communication interface 1301 receives the physical layer signal of the 3D synchronization information and then converts the physical layer signal and sends it to the digital processing module 1310. The digital processing module 1310 can encode the signal and send it to the wireless communication module 1320; the wireless communication module 1320 can modulate the signal according to the communication protocol between the 3D glasses and broadcast the modulated first wireless signal through the antenna.

[0231] Optionally, the antenna of the wireless communication device 1300 can also receive a second wireless signal sent by the 3D glasses, and the wireless communication module 1320 can demodulate the second wireless signal and send the demodulated data to the digital processing module 1310. The digital processing module 1310 can decode the data and send the feedback information obtained after decoding to the display device through the first communication interface 1301. Optionally, the feedback information is sent to the display device through the pins used for bidirectional transmission in the first communication interface 1301, such as the pins D+ / D- corresponding to the USB2 data transmission channel in the USB Type-C interface.

[0232] Optionally, the wireless communication device 1300 can also receive control information and / or data sent by the display device through the first communication interface 1301.

Optionally, the processing unit in the processing module 1402 may include a driving unit 1430, a detection unit 1450, and may also include a control unit 1440.

[0239] based on Fig.14 In the structure shown in the figure, after the antenna of the 3D glasses 1400 receives the first wireless signal, the wireless communication module 1420 demodulates the first wireless signal and sends the demodulated data to the digital processing module 1410. The digital processing module 1410 decodes the data, obtains 3D synchronization information and sends it to the processing module 1402.

[0242] Optionally, the 3D glasses 1400 may further include a power supply module 1460 , which may supply power to modules such as the digital processing module 1410 and the wireless communication module 1420 .

The type of the detection unit and the type of feedback information may be described in detail below.

[0245] In some embodiments of the present application, after the wireless communication device is connected to the display device, a communication interface initialization process is performed. In this process, the display device can obtain the device type of the wireless communication device, and based on the device type, determine that a wireless communication device is connected, and then control its internal switch to turn on the output channel of the 3D synchronization information, so as to send the 3D synchronization information to the 3D glasses through the wireless communication device. Fig.15 The schematic diagram of the above-mentioned switching switch control process is exemplified.

[0246] The method provided in the embodiment of the present application is introduced by taking a display device and a wireless communication device as examples. It should be understood that the display device in the embodiment of the present application can be a display device, or a chip, unit or module in a display device. For example, the display device can be the aforementioned Fig.11 or Fig.12 The display device 1100 in the embodiment of the present application can be a display device 1100. The display device can also be a communication device with a display device function or a chip, unit or module inside a communication device with a display device function. The wireless communication device in the embodiment of the present application can be a signal transceiver, or a chip, unit or module in a signal transceiver.

[0247] See also Fig.15 , is a schematic diagram of a switch control process provided in an embodiment of the present application. The process is executed by a display device.

[0248] like Fig.15 As shown, the process may include the following steps:

[0249] Step 1501: The display device detects that an external device is connected.

[0250] In one possible case, when an external device is connected to the display apparatus, the voltage of one or some pins in the first communication interface and / or the second communication interface of the display apparatus may change, so that it can be determined that an external device is connected based on the voltage change.

[0251] Taking the USB Type-C interface as an example, after the USB Type-C interface of the display device is connected to the USB Type-C interface of the external device, the display device can determine that an external device is connected by detecting the voltage change of the CC1 / CC2 pins in its USB Type-C interface.

[0252] Step 1502: The display apparatus identifies the type of the external device.

[0253] When the display device detects that an external device is connected, it can enter the interface initialization process. In the interface initialization process, the display device can obtain relevant information of the external device, so that the display device can determine the type of the external device.

[0254] Taking the USB Type-C interface as an example, in the device enumeration stage of the interface initialization process, the external device can send its device descriptor to the display device through the D+ / D- pin corresponding to the USB2 data transmission channel in the USB Type-C interface. The descriptor may include the device's manufacturer identification, product identification, category code and other information. The display device can determine the type of the external device based on the device descriptor of the external device.

[0255] Step 1503 : If the display apparatus determines that the external device is a 3D signal transmitter type device, then the process proceeds to step 1504 ; otherwise, the process proceeds to step 1505 .

[0256] Step 1504: The processor in the display device controls the switch to connect the first interface (3D SYNC) on the processor in the display device to the first communication interface.

[0257] The specific implementation of this step can refer to the above embodiment and will not be described again here.

[0258] Furthermore, after step 1504, or before step 1504, or while executing step 1504, the process may also proceed to step 1505 to perform other processes of interface initialization.

[0259] Step 1505: Perform other processes of interface initialization.

[0260] For example, the processor in the display device may allocate resources (such as setting addresses) for the connected external device. For another example, if the external device is a 3D signal transmitter type device, the processor in the display device may switch to a 3D video mode.

[0261] Taking the wireless communication device in the embodiment of the present application as an example, after the interface initialization is completed, a wired two-way communication link can be established between the display device and the wireless communication device, and the wireless communication device can also establish a wireless two-way communication link with the 3D glasses. The embodiment of the present application does not limit the specific implementation method of the establishment process of the above communication link.

[0262] Thereafter, information can be transmitted between the display device, the wireless communication device and the 3D glasses through the established communication link to implement the display method provided in the embodiment of the present application.

[0263] In some other embodiments of the present application, the display device itself has the signal conversion function of the wireless communication device, that is, the display device can convert 3D synchronization information into a first wireless signal for transmission, receive a second wireless signal, and can further convert control information into a third wireless signal for transmission. In other words, the display device does not need to be connected to a wireless communication device. Accordingly, the processor in the display device can control the switching switch to connect the first interface (3D SYNC) on the processor in the display device to the first communication interface in the following cases:

[0264] Case 1: The display device receives feedback information from the 3D glasses, and the feedback information is used to indicate the start of 3D video playback. For example, the feedback information may be user operation information generated by the user triggering a 3D video mode button on the 3D glasses, or for another example, the feedback information may be user operation information of the user turning on or wearing the 3D glasses.

[0265] Case 2: The display device receives information about the user's operation on the display device, and the information is used to request to start 3D video playback. For example, the user can request to play the 3D video through a voice command or a command issued by a remote control, and the display device controls the switch to connect the first interface (3DSYNC) on the processor in the display device to the first communication interface according to the command.

[0266] It can be understood that the above only exemplifies several situations that may trigger the processor of the display device to control the switching switch to connect the first interface (3D SYNC) on the processor to the first communication interface, and the embodiments of the present application are not limited to this.
