Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] Figure 1 A block diagram showing the main functional modules of the smart wearable device 100 according to an embodiment of the present application is shown in FIG. Figure 1 As shown, the device includes a main control module 110, a first driving module 120, a switching circuit 130, a second driving module 140 and a display module 150;

[0026] The first driving module 120 includes a boost unit 121, which is used to convert the received first electrical signal output by the main control module 110 into a second electrical signal; wherein the voltage corresponding to the second electrical signal is greater than the voltage corresponding to the first electrical signal;

[0027] The first driving module 120 and the first driving module 140 are connected via a switching circuit 130, and the switching circuit 130 is used to transmit the second electrical signal from the first driving module 120 to the first driving module 140;

[0028] The first driving module 140 includes a step-down unit 141, which is used to convert the received second electrical signal into a third electrical signal and output the third electrical signal to the display module 150 to supply the display module 150 for operation; wherein the voltage corresponding to the third electrical signal is smaller than the voltage corresponding to the second electrical signal.

[0029] Among them, the smart wearable device 100 can be AR / VR glasses or other wearable devices with a display module. The voltage corresponding to the first electrical signal output by the main control module 110 is also the power input voltage of the smart wearable device. The switching circuit can be a flexible printed circuit (FPC). The first drive module 120 is the main drive board of the smart wearable device, and the first drive module 140 is a dedicated driver for the display module 150.

[0030] A boost unit 121 is configured in the first driving module 120, so that the voltage of the electrical signal output by the first driving module 120 to the switching circuit 130 is greater than the power input voltage, thereby reducing the power loss caused by the transmission impedance of the switching circuit 130 during the transmission of the electrical signal. Furthermore, a buck unit 141 is provided in the first driving module 140 to adjust the voltage of the received electrical signal back to a stable value, which can not only prevent the excessively high voltage after boosting from affecting the normal operation of the display module, but also ensure the power supply stability of the display module.

[0031] More preferably, a step-down unit 141 may be provided to reduce the voltage corresponding to the second electrical signal to the rated operating voltage of the display module 150, so that the voltage corresponding to the third electrical signal received by the display module 150 just meets the operating requirements of the display module 150, thereby avoiding waste of power energy and ensuring that the display module 150 does not have abnormal display due to an excessively low operating voltage, thereby maintaining normal and stable operation of the display module 150.

[0032] Taking the smart wearable device 100 as AR glasses and the display module 150 as a liquid crystal on silicon (LCOS) display module as an example, the LCOS display module is gradually being used in the AR display field due to its advantages such as high brightness, high resolution, and high frame rate. Unlike traditional display modules that can be directly driven and lit through MIPI (Mobile Industry Processor Interface) signals, the LCOS display module needs a dedicated chip to drive it. However, due to the small and thin setting of AR glasses, the locations where hardware boards can be placed in AR glasses are relatively scattered, and the circuit modules therein need to be split. The main driver board of the AR glasses and the LCOS dedicated driver board will be set far away.

[0033] like Figure 2As shown, the main driver board of the AR glasses is placed inside the temples. The LCOS dedicated driver board needs to drive the LCOS display module for display, so it is placed above the frame following the LCOS display module. The main driver board and the LCOS dedicated driver board need to be connected through FPC or adapter cables. The power supply voltage for normal operation of LCOS is generally lower than 1.8V, and at the same time the corresponding current is relatively large. LCOS is more sensitive to power supply voltage fluctuations. FPC or adapter cables increase the impedance during transmission and amplify the fluctuation range of the power supply voltage, making it easy for LCOS to cause power supply instability when it is powered on or disturbed during operation, resulting in abnormal display of the LCOS module screen or even screen shutdown, affecting the user experience.

[0034] The smart wearable device in the embodiment of the present application can be provided with a boost unit at the main driving board to increase the voltage during the FPC transmission process, and a buck unit at the LCOS dedicated driving board to adjust the received FPC transmission voltage back to the rated working voltage of the LCOS. Figure 3 The figure shows the changing waveforms of voltage and current in the power transmission path of the LCOS display module.

[0035] like Figure 3 As shown, after the electrical signal of the power supply enters the main driving board, its voltage Vin (that is, the power supply voltage) is increased to V1 by the boost unit, and after the boosted V1 is transmitted to the LCOS dedicated driving board through the FPC, it is reduced to the rated working voltage V2 of the LCOS display module by the buck unit set in the LCOS dedicated driving board. Assuming that the corresponding powers during the transmission of the electrical signal are roughly equal, since V1>V2, the current I1 corresponding to V1 is less than the current I2 corresponding to V2, that is, the current I1 during the FPC transmission process is greatly reduced compared to not setting the boost unit and the buck unit 141. Assuming that the impedance during the transmission process is R, because the impedance R is fixed, the power loss I1*R caused by the impedance R is also greatly reduced.

[0036] More preferably, in an actual setting, the voltage value corresponding to the second electrical signal can be set to be three times or more of the voltage value corresponding to the third point signal, so as to fully reduce the power loss during the transmission process.

[0037] Therefore, the smart wearable device in the embodiment of the present application not only stabilizes the operating voltage of LCOS and improves the voltage quality, which can avoid abnormal display or screen off caused by voltage quality reasons, but also greatly reduces the power loss caused by transmission impedance and improves the power life.

[0038] In one implementation, the main control module 110 is used to receive user operation data and generate a first video signal according to the operation data, wherein the first video signal is a signal corresponding to the video determined by the main control module 110 according to the operation data.

[0039] Among them, the user's operation data may include a selection and playback operation for a specific video or other operations that can determine the content played by the smart wearable device 100. The main control module 110 can generate a video signal corresponding to the playback content determined by the user based on the user's operation, so that the display module 150 can display the corresponding video to the user.

[0040] In one embodiment, Figure 4 As shown, the first driving module 120 also includes a first driving unit 122, which is used to receive the first video signal generated by the main control module 110 and convert the first video signal into a second video signal; wherein the second video signal has a different format from the first video signal; the second driving module 140 also includes a second driving unit 142, which is used to receive the second video signal and drive the display module 150 to display the video corresponding to the second video signal.

[0041] Among them, the format of the first video signal provided by the main control module 110 can be DP / HDMI, etc., and the second video signal can be a video signal format such as MIPI that can be recognized by the second driving module 140. The first driving unit 122 can convert the video signal provided by the main control module 110 into a video signal that can be recognized by the second driving module 140, thereby completing the video bridging conversion.

[0042] The second driving unit 142 in the second driving module 140 may receive the second video signal converted by the first driving unit 122 , and drive the display module 150 to display corresponding video content.

[0043] In one implementation, the main control module 110 is further configured to generate a first control signal according to the operation data, wherein the first control signal is configured to adjust the display configuration of the display module 150 according to the operation data.

[0044] It is understandable that the user's operation data is not limited to the selection and determination of video content, but may also include control of the display configuration of the display module 150, such as display brightness adjustment, display zoom adjustment, etc. The main control module 110 can generate a control signal corresponding to the operation data based on the user's operation data to adjust the display configuration of the display module 150.

[0045] In one embodiment, the device also includes a logic control module, which is used to receive a first control signal and determine the executableness of the first control signal. The logic control module is also used to convert the first control signal into a second control signal based on the priority information carried by the first control signal and the executableness of the first control signal. The second control signal is used to control the second driving module 140 to adjust the display configuration of the display module 150.

[0046] Among them, the first control signal generated by the main control module 110 according to the user's operation data is not fully executable, and it is also necessary to judge the executability. For example, the user's operation data is display brightness adjustment, and the first control signal generated is a brightness adjustment signal (including increasing the display brightness or decreasing the display brightness). The logic control module needs to judge whether the brightness can be further increased or decreased according to the current brightness in the display configuration of the display module 150; for another example, the user's operation data is display zoom adjustment, and the first control signal generated is a zoom control signal. The logic control module needs to judge whether the current playback content can be further zoomed and controlled according to the zoom ratio of the current playback content.

[0047] It can be understood that the control signal received by the logic control module includes not only the first control signal generated by the main control module 110 according to the user operation data, but may also include the autonomous adjustment control signal generated by the main control module 110 based on the equipment operation status, etc. These signals may not be executed at the same time as the first control signal, and there may even be conflicts in simultaneous execution between different first control signals. Therefore, the priority information carried by the control signal can reflect its importance and facilitate the orderly execution of the control signal.

[0048] Exemplarily, if the first control signal is a brightness adjustment signal for the user to lower the display brightness, after receiving the first control signal, the logic control module determines that the current brightness of the display module 150 still has room to be reduced, and therefore the first control signal is executable. At the same time, the logic control module also receives a control signal for increasing the display brightness that is automatically generated by the main control module 110 according to the brightness of the external environment. Since the first control signal is generated according to user operation data, when user operation priority is set, the logic control module can convert the first control signal into a second control signal, and the second control signal can control the execution of the demand for reducing the display brightness in the first control signal, and does not execute the control signal for increasing the display brightness that is automatically generated by the main control module 110 according to the brightness of the external environment.

[0049] Based on this, the smart wearable device 100 in the embodiment of the present application can determine the executability of the control signal and convert the control signal according to the priority, so that various signal instructions in the device can be carried out in an orderly manner.

[0050] In one embodiment, the second driving unit 142 can drive the display module 150 to display corresponding content according to the second video signal or the second control signal. For example, the second video signal can be a video signal corresponding to a movie being watched by a user, and the second driving unit 142 can maintain the playback of the movie on the display screen according to the second video signal; the second control signal can be a control signal corresponding to a control interface called by the user, and the second driving unit 142 can drive the display screen to display the control interface for the user's control operation according to the second control signal.

[0051] The second driving unit 142 can also drive the display module 150 to display corresponding content according to the second video signal and the second control signal at the same time. For example, the second video signal can be a video signal corresponding to the movie being watched by the user, and the second control signal can be a control signal for increasing or decreasing the brightness controlled by the user. The second driving unit 142 can combine the second video signal and the second control signal to make the brightness of the next frame of the movie image displayed by the display module 150 meet the user's control of the brightness, and at the same time display the display brightness controller in a floating window when the movie image is displayed on the display screen, so that the user can understand the brightness adjustment. For another example, the second video signal can be a video signal corresponding to a real external image (such as a game scene in a football field), and the second control signal can be a video zoom control signal. The second driving unit 142 can combine the second video signal and the second control signal to make the next frame of the external image displayed by the display module 150 meet the image ratio adjusted according to the video zoom control signal.

[0052] Based on this, the smart wearable device 100 of the embodiment of the present application can coordinate and process the video signal and the control signal corresponding to the user operation data to ensure the smooth execution of other functions while satisfying the user's viewing experience.

[0053] In one embodiment, Figure 4 As shown, the device also includes a logic control module and at least one sensor. The logic control module is used to receive sensor data collected by at least one sensor and send the sensor data to the main control module 110. The sensor data includes at least one of external image data, external light intensity data and obstacle distance data.

[0054] The main control module 110 is used to receive sensor data and generate a third control signal according to the sensor data, wherein the third control signal is used to control the display module 150 to display the sensor data, or the third control signal is used to adjust the display configuration of the display module 150 according to the sensor data.

[0055] Among them, the sensor can be a camera, a light intensity sensor or a distance perception sensor, etc. If the user needs the display screen of the smart wearable device 100 to display the real image of the outside world, for example, in the scene of watching a game on a stadium, the viewing area where the user is located is far away from the game venue, and the naked eye cannot clearly see the game situation, the camera carried by the smart wearable device 100 such as AR glasses can be controlled to collect the game scene in the distance, so that the main control module 110 generates a third control signal to display the external image data, and displays the game scene in the form of an image on the display screen; if the user sets the brightness of the display screen to follow the changes in the external brightness, the light intensity sensor can collect the external light intensity data in real time, so that the main control module 110 adaptively generates a third control signal for adjusting the display brightness according to the external light intensity data; the distance perception sensor can sense the distance between the user and the external obstacle during the user's use of the smart wearable device 100, so that the main control module 110 generates a third control signal to remind the user to pay attention to the obstacle when judging that the distance between the user and the external obstacle is too close, so as to prevent the user from being injured by touching the obstacle due to movement during watching the video.

[0056] Furthermore, the logic control module can also determine the executability of the third control signal, and convert the third control signal according to its executability and the priority information it carries. The specific process is similar to the processing process of the logic control module for the first control signal, and will not be repeated here.

[0057] In one embodiment, the logic control module is used to control the boost unit and the buck unit to enter the working state when it is detected that the display module 150 is started, and the boost unit enters the working state earlier than the buck unit; and, when it is detected that the display module 150 is turned off, control the boost unit and the buck unit to exit the working state, and the buck unit exits the working state earlier than the boost unit.

[0058] It is understandable that for smart wearable devices, the display module 150 does not need to be in working condition all the time. Taking AR glasses as an example, when the user interrupts watching videos and handles other matters or only uses the music playback function to listen to songs, the display module 150 does not need to respond to the display. In this process, since the display module 150 is not working, there is no need to ensure that the display module 150 has a stable operating voltage. For the purpose of saving energy, the boost unit 121 and the buck unit 141 do not need to work.

[0059] Starting the display module 150 can be understood as the user starting the display module 150 by touching the display screen switch button or performing voice control or other operations. When the display module 150 is detected to be started, in order to ensure that the display module 150 has a stable operating voltage, it is necessary to control the boost unit 121 and the buck unit 141 to enter the working state, and because the electrical signal enters the boost unit 121 first, it is necessary to ensure that the boost unit 121 enters the working state earlier.

[0060] Turning off the display module 150 can be understood as the user turning off the display module 150 by touching the display switch button or performing voice control or other operations. When it is detected that the display module 150 is turned off, the buck unit 141 can be controlled to stop working before the boost unit 121 to cut off the electrical signal transmitted to the first drive module 140, thereby ensuring that the display module 150 responds to the user's closing operation in a timely manner.

[0061] The present application also provides a signal control method, which can be applied to the smart wearable device 100 in the present application, and is executed by the first driving module and the second driving module in the smart wearable device in cooperation. Figure 5 is a flow chart of a signal control method according to an embodiment of the present disclosure, comprising:

[0062] Step S501, receiving a first electrical signal output by a main control module, and converting the first electrical signal into a second electrical signal; wherein a voltage corresponding to the second electrical signal is greater than a voltage corresponding to the first electrical signal;

[0063] Step S502, converting the second electrical signal into a third electrical signal, and outputting the third electrical signal to the display module to supply the display module to operate; wherein the voltage corresponding to the third electrical signal is the rated operating voltage of the display module and is less than the voltage corresponding to the second electrical signal.

[0064] Among them, step S501 is executed by the first driving module, and after receiving the first electrical signal from the main control module, the first electrical signal can be converted into a second electrical signal to increase the voltage corresponding to the electrical signal. Due to the small and lightweight setting of the smart wearable device, the first driving module including the main driving board and the second driving module including the dedicated driver of the display module are arranged at a long distance in the smart wearable device. The second electrical signal needs to be transmitted from the first driving module to the second driving module via a longer distance switching line. Step S502 is executed by the second driving module, and the received second electrical signal can be converted into a third current signal whose corresponding voltage is the rated working voltage of the display module, thereby ensuring the voltage quality of the display module and avoiding abnormal display or screen off due to voltage quality reasons.

[0065] Furthermore, since the voltage corresponding to the second electrical signal is relatively high and the current corresponding to the second electrical signal is relatively small during transmission of the second electrical signal by the switching line, power loss caused by transmission impedance in the switching line is reduced and power life is improved.
