[0037] 100 Control device DETAILED DESCRIPTION

[0038] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0039] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0040] Figure 1 FIG. 1 is a schematic diagram of a control device for projection glasses according to an exemplary embodiment. Figure 1 As shown, the control device 100 of the projection glasses includes a main control module 1 and a first conversion module 2.

[0041] The main control module 1 is used to convert the format of the wireless video signal received from the wireless signal source device wirelessly, and receive an indication signal for indicating the current receiving mode of the projection glasses, which includes wired mode and wireless mode;

[0042] The first conversion module 2 is used for converting the format of the wired video signal received from the wired signal source device in a wired manner;

[0043] The main control module 1 is also used to control the wireless video signal or the wired video signal to be input into the screen of the projection glasses in a predetermined format according to the indication signal.

[0044] Wireless methods include: wifi or Bluetooth. Wired methods include: data cables. Data cables may include: High Definition Multimedia Interface (HDMI) data cables or (DisplayPort, DP) data cables. Exemplarily, the indication signal for indicating the current receiving mode of the projection glasses can be triggered according to the user's choice. For example, a "connection mode switch button" can be set on the projection glasses, and the user can trigger the indication signal indicating the current receiving mode of the projection glasses by touching the button.

[0045] Exemplarily, the indication signal for indicating the current receiving mode of the projection glasses can be triggered by the wifi module or DP interface of the projection glasses. When the DP interface of the projection glasses recognizes that it is connected to the terminal device via the DP data cable, it triggers an indication signal to the main control module 1 for indicating that the current receiving mode of the projection glasses is a wired mode; when the wifi module of the projection glasses establishes a wireless connection with the wifi module of the terminal device, the wifi module triggers an indication signal to the main control module 1 for indicating that the current receiving mode of the projection glasses is a wireless mode.

[0046] After the projection glasses are connected to a wireless signal source device (such as a mobile phone) wirelessly, the wireless signal source device sends the wireless video signal to the main control module 1 wirelessly (for example, wifi). Since the screen of the projection glasses can receive a video signal in a predetermined format, after receiving the wireless video signal, the main control module 1 converts the received wireless video signal into a video signal in a predetermined format, and inputs the converted video signal into the screen of the projection glasses through an output interface corresponding to the video signal in the predetermined format.

[0047] After the projection glasses are connected to a wired signal source device (such as a computer) via a wired method, the wired video signal is sent to the first conversion module 2 via a data line (such as a DP data line). In the case where the data format of the wired video signal sent via the data line is inconsistent with the data format of the video signal that the screen can receive, the first conversion module 2 performs format conversion on the wired video signal after receiving it. The first conversion module 2 can convert the wired video signal into a data format of a video signal that the screen can receive and then transmit it to the screen, or the first conversion module 2 can also convert it into other formats, and then undergo format conversion by other modules, so that the wired video signal is finally converted into a data format of a video signal that the screen can receive.

[0048] Through the above technical solution, the control device of the projection glasses includes: a main control module and a first conversion module. The main control module is used to convert the format of the wireless video signal received from the wireless signal source device in a wireless manner, and receive an indication signal for indicating the current receiving mode of the projection glasses, and the receiving mode includes a wired mode and a wireless mode. The first conversion module is used to convert the format of the wired video signal received from the wired signal source device in a wired manner. The main control module is also used to control the input of the wireless video signal or the wired video signal into the screen of the projection glasses in a predetermined format according to the indication signal. In this way, both wired and wireless connection modes are compatible in the projection glasses, and users can choose the connection mode according to the usage scenario, which meets the user's usage needs and improves the user experience.

[0049] Figure 2 is a schematic diagram of a control device for projection glasses according to another exemplary embodiment. Figure 2-6In the wireless connection method, all are wifi, and all are DP data cables. Figure 2 As shown, the control device 100 further includes a selection module 3. The selection module 3 is connected to the main control module 1 and the first conversion module 2 respectively, and the selection module 3 is used to receive the indication signal and the wireless video signal after format conversion from the main control module 1, receive the wired video signal after format conversion from the first conversion module 2, and select one of the wireless video signal after format conversion and the wired video signal after format conversion according to the indication signal, and input it into the screen.

[0050] When the main control module 1 receives an indication signal for indicating the current receiving mode of the projection glasses, the main control module 1 sends the indication signal to the selection module 3, and the selection module 3 selects one of the converted wireless video signal sent by the main control module 1 and the converted wired video signal sent by the first conversion module 2 to input the screen according to the indication signal. The selection module 3 can receive the converted wireless video signal and the converted wired signal at the same time, or only receive one of them at the same time, and input it into the screen when the wireless video signal is received or input it into the screen when the wired video signal is received.

[0051] The interface for transmitting data between the main control module 1 and the screen may be a mobile industry processor interface (MIPI) - a high-speed serial interface (DSI) between the processor and the display module. The predetermined format may be a data format corresponding to the MIPI-DSI interface.

[0052] In this embodiment, by setting the selection module 3 in the control device 100 of the projection glasses, the wireless video signal after format conversion or the wired video signal after format conversion can be reliably input into the screen.

[0053] exist Figure 2 In the embodiment, the wireless video signal output by the main control module 1 to the selection module 3 is two-way signals, and the selection module 3 is used to transmit the two-way wireless video signals to the left screen and the right screen of the screen respectively.

[0054] The screen of projection glasses usually includes a left screen and a right screen. Figure 2 The main control module 1 includes two MIPI-DSI interfaces. When the receiving mode is wireless, the main control module 1 converts the wireless video signal received through wifi into a wireless video signal in a predetermined format (MIPI-DSI), and sends the converted wireless video signal to the selection module 3 through the two MIPI-DSI interfaces. The selection module 3 transmits the two wireless video signals to the left screen and the right screen respectively.

[0055] In this embodiment, the wireless video signal is sent to the left screen and the right screen of the screen through two signals, and the data processing speed is fast.

[0056] Figure 3 FIG. 1 is a schematic diagram of a control device for projection glasses according to another exemplary embodiment. Figure 3 As shown, the wireless video signal output by the main control module 1 to the selection module 3 is one channel signal.

[0057] The control device 100 further includes a splitter module 4. The selection module 3 is connected to the screen via the splitter module 4, and the splitter module is used to split the video signal received from the selection module 3 into two paths, and transmit them to the left screen and the right screen respectively.

[0058] exist Figure 3 In the embodiment, the main control module 1 includes a MIPI-DSI interface. When the receiving mode is wireless, the main control module 1 outputs a converted wireless video signal to the selection module 3 through the MIPI-DSI interface; when the receiving mode is wired, the converted wired video signal output by the first conversion module to the selection module 3 is also a video signal. The screen of the projection glasses includes a left screen and a right screen, and a video signal can only be input to one screen. Therefore, the converted wireless signal or the converted wired signal received from the selection module 3 can be copied into two channels through the shunt module 4 and transmitted to the left screen and the right screen respectively.

[0059] In this embodiment, by setting up a diversion module, one video signal received from the selection module 3 can be reliably and conveniently divided into two channels, so that both the left and right screens can display the picture.

[0060] Figure 4 FIG. 1 is a schematic diagram of a control device for projection glasses according to another exemplary embodiment. Figure 4 As shown, the first conversion module 2 is connected to the main control module 1 and is used to input the format-converted wired video signal into the main control module 1. The main control module 1 is used to output a video signal of a predetermined format to the screen according to the indication signal.

[0061] When the main control module 1 receives an indication signal indicating that the current receiving mode of the projection glasses is wired, the first conversion module 2 converts the received wired video signal into a format and inputs it into the main control module 1. The main control module 1 inputs the received wired video data into the screen through the MIPI-DSI interface corresponding to the predetermined format.

[0062] In this embodiment, by inputting the wired video signal after the format conversion into the main control module 1, the main control module 1 can be used to quickly and reliably input the wired video signal to the screen.

[0063] exist Figure 4 In the embodiment, the first conversion module 2 is connected to the camera signal interface of the main control module 1 and is used to convert the wired video signal into a camera signal format. The main control module 1 is also used to convert the wired video signal into a predetermined format.

[0064] The main control module 1 is provided with a camera signal MIPI-(Camera Serial Interface, CSI) interface for receiving images or videos corresponding to the data format of the camera signal interface. When the main control module 1 receives an indication signal indicating that the current receiving mode of the projection glasses is a wired mode, the first conversion module 2 converts the wired video signal transmitted through the data line (such as the DP data line) into a MIPI-CSI wired video signal, and inputs the wired video signal into the main control module 1 through the MIPI-CSI interface of the main control module 1. The main control module 1 converts the wired video signal input by the MIPI-CSI interface into a wired video signal of a predetermined format, and inputs the converted wired video signal into the screen through the MIPI-DSI interface.

[0065] In this embodiment, by connecting the first conversion module 2 to the camera signal interface of the main control module 1, the camera signal interface in the main control module 1 is reused for video signal transmission, thereby improving device utilization.

[0066] Figure 5 FIG. 1 is a schematic diagram of a control device for projection glasses according to another exemplary embodiment. Figure 5 As shown, the main control module 1 is used to output a video signal of a predetermined format to one of the left screen and the right screen in the screen according to the indication signal, and output a video signal of a different format from the predetermined format.

[0067] The control device 100 further includes a second conversion module 5. The second conversion module 5 is connected to the main control module 1 and is used to convert the format of a video signal output by the main control module 1 that is different from the predetermined format into the predetermined format and then input it into the other of the left screen and the right screen.

[0068] exist Figure 5 In the embodiment, the main control module 1 includes only one MIPI-DSI interface. Since one MIPI-DSI interface can only transmit video signals to one screen, it is necessary to transmit video signals to another screen through an interface (e.g., RGB interface) in the main control module 1 that is different from the predetermined format. Since the screen can only receive video signals in a predetermined format, the second conversion module 5 in the control device 100 of the projection glasses can convert the format of a video signal (e.g., RGB format) that is different from the predetermined format into the predetermined format and then input it into the other of the left screen and the right screen.

[0069] Exemplarily, in the wireless receiving mode, the main control module 1 converts the received wireless video signal into the MIPI-DSI format, and outputs it to the left screen through the MIPI-DSI interface. At the same time, the received wireless video signal is converted into the RGB format and output to the second conversion module 5 through the RGB interface. The second conversion module 5 converts the received wireless video signal in the RGB format into a video signal in a predetermined format and outputs it to the right screen.

[0070] Exemplarily, in the wired reception mode, the main control module 1 converts the MIPI-CSI wired video signal input through the camera signal interface into the MIPI-DSI format and inputs it into the left screen through the MIPI-DSI interface, and at the same time converts the MIPI-CSI wired video signal into an RGB format and converts it into the MIPI-DSI format through the second conversion module 5 and then inputs it into the right screen.

[0071] In this embodiment, when the main control module 1 can only output one video signal of a predetermined format to one of the left and right screens, by setting up a second conversion module 5, another video signal can be output to the other of the left and right screens by utilizing an interface in the main control module 1 that is different from the predetermined format.

[0072] Figure 6 FIG. 1 is a schematic diagram of a control device for projection glasses according to another exemplary embodiment. Figure 6 As shown, the control device 100 further includes an audio module 6 .

[0073] The audio module 6 is connected to the main control module 1 and is used to play the audio signal received from the main control module 1;

[0074] The main control module 1 is also used to convert the format of the wireless audio signal received from the wireless signal source device in a wireless manner, and receive the wired audio signal after the format conversion from the first conversion module 2;

[0075] The first conversion module 2 is further used for converting the format of the wired audio signal received from the wired signal source device in a wired manner.

[0076] When the receiving mode is a wired mode, the first conversion module 2 converts the wired audio signal received in the wired mode into a digital audio signal and inputs the digital audio signal into the main control module 1 , and the main control module 1 outputs the digital volume signal to the audio module 6 .

[0077] When the receiving mode is wireless, the main control module 1 converts the wireless audio signal received wirelessly into a digital audio signal and then inputs the digital audio signal into the audio module 6 .

[0078] In this embodiment, the audio signal can be quickly and reliably transmitted to the audio module 6 for playback through the main control module 1 in both wireless and wired modes.

[0079] exist Figure 6 In the embodiment, the audio module 6 is further used to convert the received sound signal into an electrical signal and send it to the main control module 1.

[0080] The audio module 6 can convert the sound signal sent by the sound collection device (for example, a microphone) into an electrical signal and send it to the main control module 1 .

[0081] In this embodiment, the audio module 6 can reliably and timely send the sound signal to the main control module 1 .

[0082] The present disclosure also provides a screen projection glasses, comprising a screen and a control device for the above-mentioned screen projection glasses.
