Detailed Description

In order to make the technical solutions of the present application better understood, the present application is described in detail below with reference to the accompanying drawings and the detailed description. The embodiments of the present application will be described in further detail with reference to the drawings and specific embodiments, but the present application is not limited thereto.

As used in this application, the terms "first," "second," and the like, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element preceding the word covers the element listed after the word, and does not exclude the possibility that other elements are also covered. The order of execution of the steps in the methods described in this application in connection with the figures is not intended to be limiting. As long as the logical relationship between the steps is not affected, the steps can be integrated into a single step, the single step can be divided into a plurality of steps, and the execution order of the steps can be changed according to the specific requirements.

According to an embodiment of the present application, there is provided wireless smart glasses, which may include, for example, a left glasses part and a right glasses part, wherein each of the left and right glasses parts includes components such as a processing part, a display screen, and a first wireless module, and corresponding steps in the display method for wireless smart glasses according to the various embodiments of the present application are performed by each component of each glasses part.

The application provides a wireless intelligent glasses. Fig. 1 shows a schematic diagram of a part of the components of wireless smart glasses according to an embodiment of the present application. As shown in fig. 1, the wireless smart glasses 1 may include a left glasses part 10 and a right glasses part 11, further, the left glasses part 10 at least includes a processing part 101, a display screen 102 and a first wireless module 103, wherein the display screen 102 is provided with a frame image buffer 1021, correspondingly, the right glasses part 11 at least includes a processing part 111, a display screen 112 and a first wireless module 113, and the display screen 112 is provided with a frame image buffer 1121.

In some embodiments, the first wireless module of each eyeglass portion is configured to receive video data of the smart device, for example, the first wireless module 103 of the left eyeglass portion 10 and the first wireless module 113 of the right eyeglass portion 11 respectively receive video data from the smart device 2 shown in fig. 1. The smart device 2 may be, for example, a smart phone, a pad, a computer, or a cloud server, and the application is not limited herein.

In some embodiments, the first wireless module 103 and the first wireless module 113 may be a bluetooth module, a WiFi module, or any other communication module capable of supporting wireless transmission of video data, which is not limited herein.

In some embodiments, the processing portion of each of the glasses portion may be configured to write the received video data to the frame image buffer in the respective display screen based on a synchronization reference signal cooperatively set, for example, the processing portion 101 of the left glass portion 10 writes the received video data to the frame image buffer 1021 based on a synchronization reference signal 1 (not shown), and correspondingly, the processing portion 111 of the right glass portion 11 writes the received video data to the frame image buffer 1121 based on a synchronization reference signal 2 (not shown). The processing unit of each of the glasses may decompress the video data after receiving the video data, and then write the decompressed video data into the frame image buffer of each display screen. Further, the synchronization reference signal 1 and the synchronization reference signal 2 are provided in cooperation, and the synchronization reference signals for the left and right eye parts are provided in cooperation, whereby the timings of writing the video data into the frame image buffer 1021 and the frame image buffer 1121 can be synchronized.

In some embodiments, the processing portion 101 and the processing portion 111 may be, for example, processing components including one or more general-purpose processors, such as microprocessors, Central Processing Units (CPUs), Graphics Processing Units (GPUs), and so on. More specifically, the processing element may be a Complex Instruction Set Computing (CISC) microprocessor, Reduced Instruction Set Computing (RISC) microprocessor, Very Long Instruction Word (VLIW) microprocessor, processor running other instruction sets, or processors running a combination of instruction sets. The processing element may also be one or more special-purpose processing devices such as an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), a Digital Signal Processor (DSP), system on chip (SoC), or the like.

In some embodiments, the display screen of each eyeglass portion is configured to: the video data in the respective frame image buffers are synchronously displayed. As mentioned above, since the writing timings of the video data in the frame image buffer 1021 and the frame image buffer 1121 can be synchronized, when the display screen 102 of the left lens portion 10 and the display screen 112 of the right lens portion 11 respectively use the video data in the frame image buffer 1021 and the frame image buffer 1121 for refreshing, a synchronized data base is provided, and how to ensure the synchronicity of the display screen 102 of the left lens portion 10 and the display screen 112 of the right lens portion 11 during refreshing will be described in detail later with reference to other embodiments.

In some embodiments, the Display screen 102 and the Display screen 112 may be, for example, a Liquid Crystal Display (LCD), a Liquid Crystal On Silicon (LCOS), a Digital Light Processing (DLP) Display, or other types or forms of microdisplays that are not self-illuminating, which may be flexible screens or rigid screens (i.e., non-flexible screens), and the application is not limited herein. In other embodiments, the display screen 102 and the display screen 112 may also be other types or forms of self-Emitting micro-displays such as a Light Emitting Diode (LED) display screen, an Organic Light Emitting Diode (OLED) display screen, and the like, and may be a flexible screen or a rigid screen (i.e., a non-flexible screen), which is not limited herein.

According to the intelligent glasses provided by the embodiment of the application, the video data from the intelligent equipment or the cloud can be received through the wireless module, the limitation of wires is reduced, and the user experience is greatly improved. In addition, each of the screens of the respective lens portions includes a frame image buffer, and thus belongs to a Command Mode (Command Mode) screen. For a display screen in command mode, an MIPI (Mobile Industry Processor Interface) (DSI is one of them) bus controller between a processing section and the display screen transmits a pixel data stream to the display screen using a display command message, and the display screen stores all pixel data by using a full-frame-length frame image buffer included in the display screen itself. Once the data are placed in the frame image buffer of the display screen, the timing controller may take out the data from the frame image buffer based on a certain timing signal (clock signal) and automatically display them on the display screen. In the command Mode, the MIPI bus controller does not need to refresh the display screen periodically, but only when the data screen changes, the processing unit of each glasses unit sends data to the display screen via the MIPI (for example, DSI), and otherwise the display screen (or the driving chip of the display screen) itself reads data from the internal frame image buffer and displays the data, and does not need to refresh the display periodically via the MIPI bus, so that the power consumption is lower than that in a Video Mode (Video Mode) in which the display screen is refreshed periodically via the MIPI bus without providing the frame image buffer.

Further, as for the display panel of the command mode, the frequency of the screen swiping of the display panel is F1 Hz, and the frequency of the image data transmission to the display panel by the glasses processing section may be F2 Hz. F1, F2 are often not the same, in many cases F1> F2. Thus, the command mode display screen may have lower power consumption relative to the video mode. In addition, in the command mode, data transmission between the processing part and the display screen of each glasses part is greatly reduced, and interference to wireless transmission can be reduced.

F2 tends to be a constant value when the same video file is played on each of the lens portions. F2 may be different when different video files are played on each of the lens portions. On the other hand, when some interfaces, some relatively still images are displayed on the glasses, F2 may be low and may be changed at any time or by the operation of the user, and when there is a need, for example, when there is a change in the image picture, the processing section transmits the image data to the frame image buffer of the display screen. For the above various application scenarios, no distinction is made in this application.

Fig. 2 is a schematic diagram illustrating a synchronization reference signal coordination setting manner according to an embodiment of the present application. In some embodiments, one of the left and right glasses may be a master glasses and the other may be a slave glasses, for example, in fig. 2, one of the left and right glasses may be set as a master glasses 20 and the other may be set as a slave glasses 21, and the synchronization reference signals according to the embodiments of the present application are cooperatively set as follows.

First, a first reference signal is triggered by the display screen 202 of the primary eyewear section 20 and is output to the processing section 201 of the primary eyewear section 20. That is, the display screen 202 of the primary eyewear portion 20 may be configured to trigger the first reference signal and output the first reference signal to the processing portion 201 of the primary eyewear portion 20.

Then, the first reference signal, or a third reference signal triggered based on the first reference signal, is transmitted to the processing section 211 of the slave eyeglass section 21 by the processing section 201 of the master eyeglass section 20. That is, the processing section 201 of the master eyeglass portion 20 may be further configured to transmit the first reference signal, or a third reference signal triggered based on the first reference signal, to the processing section 211 of the slave eyeglass portion 21.

After receiving the first reference signal or the third reference signal from the processing unit 211 of the glasses unit 21, the processing unit triggers a second reference signal based on the first reference signal or the third reference signal, and outputs the second reference signal to the display screen 212 of the glasses unit 21. The processing unit 211 of the slave eyeglass unit 21 may further trigger a fourth reference signal based on the first reference signal or the third reference signal, and output the fourth reference signal to the display screen 212 of the slave eyeglass unit 21 instead of the second reference signal. That is, the processing section 211 of the slave glass section 21 may be further configured to trigger a second reference signal based on the first reference signal or the third reference signal, and output the second reference signal or a fourth reference signal triggered based on the first reference signal or the third reference signal to the display screen 212 of the slave glass section 21. In some embodiments, the fourth reference signal may also be generated based on the second reference signal, for example, a signal with a fixed time delay from the second reference signal, and so on, which are not listed here.

The second reference signal and the fourth reference signal, which are generated in a coordinated manner with the first reference signal or the third reference signal as described above, will be used for display synchronization of the left and right eyeglass portions in the next step.

On the one hand, the above-mentioned respective reference signals may be used for synchronous writing of the respective frame image buffers of the left and right eyeglass portions, for example, the received video data may be written into the frame image buffer 2021 in the display screen 202 of the main eyeglass portion 20 by the processing portion 201 of the main eyeglass portion 21 based on the first reference signal. That is, the processing section 201 of the primary eyewear section 20 may be further configured to write the received video data to the frame image buffer 2021 in the display screen 202 of the primary eyewear section 20 based on the first reference signal. The received video data is written in the frame image buffer 2121 in the display screen 212 of the slave eyeglass portion 21 in synchronization with the processing portion 201 of the master eyeglass portion 20 by the processing portion 211 of the slave eyeglass portion 21 based on the second reference signal, corresponding to the master eyeglass portion 20. That is, the processing section 211 of the slave eyeglass section 21 may be further configured to write the received video data to the frame image buffer 2121 in the display screen 212 of the slave eyeglass section 21 in synchronization with the processing section 201 of the master eyeglass section 20 based on the second reference signal.

On the other hand, the above-mentioned respective reference signals may also be used for synchronous screen refreshing of the left and right eyeglass portion display screens, for example, the video data in the frame image buffer 2121 may be displayed in synchronization with the video data in the frame image buffer 2021 displayed by the display screen 202 of the master eyeglass portion 20 based on the second reference signal or the fourth reference signal by the display screen 212 of the slave eyeglass portion 21. That is, the display screen 212 of the slave eyeglass portion 21 may be further configured to: the video data in the frame image buffer 2121 is displayed in synchronization with the display screen 202 display frame image buffer 2021 of the main glasses section 20 based on the second reference signal or the fourth reference signal.

As described above, each reference signal such as the first reference signal and the second reference signal may be an applicable rising edge, falling edge, or narrow pulse trigger signal, for example, a TE pin is provided between the display screen (or the display screen driving chip) of each glasses portion and the processing portion, and the display screen driving chip may transmit a TE (defining Effect signal) signal to the processing portion by using the TE pin, so as to inform the processing portion that the display screen has been refreshed, and new frame data can be transmitted. In some embodiments, the display screen of the primary eyewear portion may generally employ a TE signal (e.g., a rising or falling edge of the TE signal, or a signal generated based on a TE pulse signal, etc.) as the first reference signal. The TE signal as the first reference signal is transmitted from the display screen (or the display screen driving chip) of the master glasses section to the processing section of the master glasses section, and the transmission direction of the second reference signal cooperatively set based on the first reference signal is opposite, and is output from the processing section of the glasses section to the display screen of the slave glasses section, so that the display screen of the slave glasses section can perform synchronous data update and screen refreshing display with the display screen of the master glasses section.

Through the above-described respective steps, the display screen 202 of the master eyeglass portion 20 and the display screen 212 of the slave eyeglass portion 21 can be made to write video data in the respective frame image buffers in synchronization. And under the condition that the first reference signal is triggered based on the TE signal, the pace that the processing parts of the respective glasses parts send data to the frame image buffer and the refresh pace of the corresponding display screen can be kept consistent, and as long as the initial time of writing data into the frame image buffer is earlier than the time of starting refreshing the display screen, and the data writing speed is higher than the refresh display speed of the display screen, the data used for refreshing the display screen can be ensured to be the updated data in the frame image buffer, so that the screen cut phenomenon that new and old data are the same in one screen can be avoided.

In some other embodiments, the first reference signal or the third reference signal triggered based on the first reference signal may be transmitted by the processing section of the master glasses section to the processing section of the slave glasses section by means of a wired connection. That is, the processing section of the master eyeglass portion may be further configured to transmit the first reference signal, or a third reference signal triggered based on the first reference signal, to the processing section of the slave eyeglass portion using a wired connection. The processing portion of the primary eyewear portion is further configured to: the first reference signal or a third reference signal triggered based on the first reference signal is transmitted to a processing section of the slave eyeglass section using a wired connection. In some embodiments, the wired connection for transmitting the first reference signal or the third reference signal may be a signal line exclusively provided between the processing section of the master eyeglass portion and the processing section of the slave eyeglass portion, or may be an existing idle signal line configured to transmit the first reference signal or the third reference signal. The reference signals required by synchronization between the master glasses part and the slave glasses part are transmitted through wired connection, so that the time delay is smaller, the time sequence configuration of each subsequent signal is more convenient, the consistency and synchronization are easier to achieve, and the overall time delay is smaller.

In some embodiments, the processing portion of each of the left and right eyeglass portions is connected to a corresponding display screen or a display screen driving chip (or a driving module integrally provided with the display screen) via a GPIO (General-purpose input/output) interface, and the processing portions of the respective eyeglass portions are connected to each other via the GPIO interface. As shown in fig. 2, the processing section 201 of the master glasses section 20 is connected to the display screen 202 or the display screen driving chip 202' of the master glasses section 20 via a GPIO interface, the processing section 211 of the slave glasses section 21 is connected to the display screen 212 or the display screen driving chip 212' of the slave glasses section 21 via a GPIO interface, and the display screen 202 or the display screen driving chip 202' of the master glasses section 20 triggers the first reference signal and outputs the first reference signal to the processing section 201 of the master glasses section 20 via the GPIO interface. Then, a third reference signal is triggered by the processing section 201 of the master glasses section 20 based on the first reference signal and is output to the processing section 211 of the slave glasses section 21 via the GPIO interface. Further, a second reference signal may be triggered by the processing portion 211 of the slave glasses portion 21 based on the third reference signal, and the second reference signal, or a fourth reference signal triggered by the first reference signal or the third reference signal may be output to the display screen 212 or the display screen driving chip 212' of the slave glasses portion 21 via a GPIO interface.

That is, the display screen 202 of the primary eyewear section 20 may be further configured to trigger the first reference signal by the display screen 202 or the display screen driving chip 202' of the primary eyewear section 20 and output the first reference signal to the processing section 201 of the primary eyewear section 20 via the GPIO interface; the processing section 201 of the master glasses section 20 is further configured to trigger a third reference signal based on the first reference signal and output the third reference signal to the processing section 211 of the slave glasses section 21 via the GPIO interface; the processing section 211 of the slave glasses section 21 may be further configured to trigger a second reference signal based on the third reference signal and output the second reference signal or the fourth reference signal to the display screen 212 or the display screen driving chip 212' of the slave glasses section 21 via the GPIO interface.

Therefore, the GPIO is used for transmitting the third reference signal, synchronous display of video signals received by the left glasses part and the right glasses part through wireless can be achieved, the implementation scheme is simplified, the cost of software and hardware for achieving synchronization through wireless receiving between the left glasses part and the right glasses part is reduced, interference of wireless connection between the left glasses part and the right glasses part on receiving wireless video of the left glasses part and the right glasses part is reduced, and occupation of time slots of wireless connection between the left glasses part and the right glasses part on receiving wireless video is avoided. In some embodiments, the third reference signal may also be a rising or falling edge or a narrow pulse trigger signal. In some embodiments, the second reference signal and the third reference signal may be triggered by a rising edge or a falling edge of the wireless receiving clock or the display clock. In some embodiments, the second reference signal may be the third reference signal or the third reference signal is obtained after a fixed time delay, or triggered by the third reference signal.

In the display method for the smart glasses according to the embodiment of the application, when the display screens of the master glasses part and the slave glasses part are respectively brushed based on the first reference signal and the second reference signal which are cooperatively set, because the first reference signal and the second reference signal are cooperatively set, the display screen of the master glasses part and the display screen of the slave glasses part can be ensured to be synchronously brushed or synchronously brushed, so that videos or images on the display screens of the left and right glasses parts have stronger stereoscopic impression, and the method is more natural and real and has better user wearing experience.

The subsequent method and steps for triggering the second reference signal by the processing portion of the slave glasses portion based on the first reference signal or the third reference signal and outputting the second reference signal to the display screen of the slave glasses portion, and writing the received video data into the frame image buffer in the corresponding display screen by the processing portion of the master glasses portion and the processing portion of the slave glasses portion based on the first reference signal and the second reference signal respectively are similar to the foregoing, and are not repeated herein.

In some embodiments, the processing portion of each of the left and right eyeglass portions is connected to the corresponding display screen through a DSI serial port, and each DSI serial port has a corresponding DSI clock, and the received video data may be written into the frame image buffer in the respective display screen by the processing portion of each eyeglass portion based on the respective DSI clock. As shown in fig. 3, either one of the left and right eyeglass portions serves as a master eyeglass portion 30, the other serves as a slave eyeglass portion 31, the processing portion 301 of the master eyeglass portion 30 may be connected to the display screen 302 through a DSI serial port, and the processing portion 301 of the master eyeglass portion 30 is further configured to write received video data to a frame image buffer 3021 in the display screen 302 of the master eyeglass portion 30 based on a DSI clock of the DSI serial port; the processing section 311 of the slave eyeglass portion 31 may be connected to the display screen 312 through a DSI serial port, and the processing section 311 of the slave eyeglass portion 31 may be further configured to write the received video data to the frame image buffer 3121 in the display screen 312 of the slave eyeglass portion 31 in synchronization with the processing section 301 of the master eyeglass portion 30 based on a DSI clock of the DSI serial port.

In some embodiments, the first reference signal may be selected to be associated with the DSI clock of the master eyewear portion 30, and the second reference signal may be selected to be associated with the DSI clock of the slave eyewear portion 31 in the same manner as the first reference signal. The following will describe in detail the selection manner and transmission manner of the first reference signal and the second reference signal, and the manner of calibrating the DSI clock of the left and right eyeglass portions by using the first reference signal and the second reference signal in a wireless transmission manner.

In some embodiments, a second wireless module may be provided in each of the left and right eyeglass portions, wherein the second wireless module is a bluetooth module or a WiFi module. The second wireless module may be used to transmit audio data, video data, image data or other control commands, etc. from the smart device. In some embodiments, the second wireless module may be the same wireless module as the first wireless module, or may be a wireless module equipped additionally. In some embodiments, the clock signal of the second wireless module of the left eyeglass portion is synchronized with the clock signal of the second wireless module of the right eyeglass portion. As shown in fig. 3, the second wireless module 304 is disposed in the master glasses part 30, the second wireless module 314 is disposed in the slave glasses part 31, both the second wireless module 304 and the second wireless module 314 may be bluetooth modules, or both WiFi modules, and the clock signal of the second wireless module 314 and the clock signal of the second wireless module 304 are always synchronized. Specifically, taking the second wireless module 304 and the second wireless module 314 as bluetooth modules as an example, the two bluetooth modules may receive bluetooth data of the same intelligent device (not shown), and may keep bluetooth clocks of the two bluetooth modules synchronized with a bluetooth clock of the intelligent device through a bluetooth Access Code (Access Code) of a physical layer or a correlation process of a part of the Access Code, so that clocks of the two bluetooth modules are also synchronized. In the case where the second wireless module 304 and the second wireless module 314 are both WiFi modules, similarly, both WiFi modules can receive WiFi data of the same smart device (not shown), and by receiving a periodic WiFi Beacon signal (i.e., Beacon), the WiFi clocks of both WiFi modules can be synchronized with the WiFi clock of the smart device, and thus the clocks of both WiFi modules are also synchronized.

However, normally, the DSI clocks of the left and right eyeglass portions are not necessarily synchronized with the clocks of the second wireless modules of the same eyeglass portion, and therefore, the DSI clocks of the left and right eyeglass portions may be calibrated by the clocks of the second wireless modules on the premise that the clocks of the two second wireless modules are synchronized as described above. Specifically, for example, a field synchronization signal of a DSI serial port or an SOT (start of transmission) start signal of the DSI serial port between the processing unit of the main glasses part and the display screen of the main glasses part may be generated by using the first reference signal generated by the display screen 302 of the main glasses part 30 as a reference, and the clock signal (bluetooth clock or WiFi clock) of the second wireless module 304 corresponding to the time of the signal may be triggered (or locked) by using the first reference signal, the field synchronization signal, the SOT start signal, or the like, or a signal obtained by fixedly delaying the above signals, so as to obtain a first clock value corresponding to the second wireless module 304 corresponding to the time of the signal, and transmit the first clock value to the processing unit 301 of the main glasses part 30. Since the above signals are generated based on the first reference signal, i.e. are all associated with the first reference signal, for convenience of description, only the clock signal of the second wireless module 304 at the time when the first reference signal triggers the first reference signal will be described as an example. The processing unit 301 of the master glasses unit 30 may transmit the received first clock value to the processing unit 311 of the slave glasses unit 31 by wireless transmission using the second wireless module 304 of the master glasses unit 30. That is, the processing section 301 of the master eyeglass portion 30 may be further configured to transmit a first clock value of a clock signal of the second wireless module 304 corresponding to the master eyeglass portion at the time of receiving the first reference signal transmitted by the display screen 302 thereof to the processing section 311 of the slave eyeglass portion 31 using the second wireless module 304 of the master eyeglass portion 30.

Next, the DSI clock of the DSI serial port of the slave eyeglass portion 31 may be calibrated by the processing portion 311 of the slave eyeglass portion 31 according to the first clock value received via the second wireless module 314, so that the DSI clock of the DSI serial port of the slave eyeglass portion 31 and the DSI clock of the DSI serial port of the master eyeglass portion 30 keep synchronized, as follows. First, the processing unit 311 of the slave eyeglass unit 31 may generate the second reference signal associated with the DSI clock of the slave eyeglass unit in cooperation with the first reference signal, and the second reference signal may select the SOT signal of the display screen 312 when the SOT signal of the display screen 302 is selected by the first reference signal, which is not listed here. The second reference signal is then used to trigger (or lock) the clock signal of the second wireless module 314 at the time of the second reference signal to obtain a second clock value corresponding to the second wireless module 314 at the time of the second reference signal. Further, the second clock value is compared with the first clock value received via the second wireless module of the slave glasses part, and since the clock signals of the second wireless module 304 and the second wireless module 314 can be considered to be synchronous, the difference between the first clock value and the second clock value can be considered to be the difference between the DSI clocks of the master glasses part 30 and the slave glasses part 31, and therefore, the DSI clock of the DSI serial port of the slave glasses part 31 can be calibrated based on the difference between the first clock value and the second clock value, so that the DSI clock of the DSI serial port of the slave glasses part 31 and the DSI clock of the DSI serial port of the master glasses part 30 keep synchronous. In some embodiments, the DSI clock of the display screen 312 of the slave glasses part 31 may be adjusted to be consistent with the DSI clock of the master glasses part 30, for example, by adjusting a phase-locked loop generating the DSI clock, or by adjusting an integer number of DSI clock cycles according to a clock value difference.

According to the wireless intelligent glasses, the synchronization of the DSI clocks between the master glasses part and the slave glasses part is calibrated according to the above manner, so that the second reference signal related to the DSI clock triggered by the processing part of the slave glasses part can be consistent with the time of the first reference signal, the processing parts of the master glasses part and the slave glasses part can synchronously write in the frame image buffers of the corresponding display screens, and the display screens of the master glasses part and the slave glasses part can synchronously swipe in the screen.

Fig. 4(a) shows a schematic diagram of a left glasses part and a right glasses part synchronously displaying video data based on a first reference signal and a second reference signal, respectively, according to an embodiment of the present application.

In some embodiments, it often takes a certain time for the processing portion of the master glasses portion to transmit the first reference signal to the processing portion of the slave glasses portion, especially when the first reference signal is transmitted wirelessly, the required time may be several hundreds of μ s, several ms, even ten and several ms, and therefore, the processing portion of the slave glasses portion often receives the first reference signal after a certain time delay after the time when the processing portion of the master glasses portion receives the first reference signal triggered by the display screen thereof, and therefore, the triggering time of the second reference signal triggered based on the first reference signal may have a certain time interval with the triggering time of the first reference signal. As shown in FIG. 4(a), assume t triggered by the first reference signal of the primary eyeglass portion ₁ The time and t of receiving the first reference signal from the glasses part and triggering the second reference signal based on the first reference signal ₂ The time difference is T3 long, then the processing part of the main glasses part can be used for T ₂ At that time, the received video data is written into the frame image buffer in the display screen of the master glasses part, and correspondingly, the processing part of the slave glasses part is also triggered at t by the second reference signal ₂ At this time, the second reference signal is input to the display screen of the slave eyeglass portion, and the video data is written into the frame image buffer based on the second reference signal, so that the display screen of the slave eyeglass portion can have the video data synchronized with the master eyeglass portion when the screen is flushed with the data in the frame image buffer. That is, in the case where the triggering time of the second reference signal differs from the triggering time of the first reference signal by a time period of T3, the processing section of the main glasses section may be further configured to write the received video data to a frame image buffer in the display screen of the main glasses section at a time after a time period of T3 after the triggering of the first reference signal. In some embodiments, T3 may be a fixed value, may be configured, or may be determined through testing in a software and hardware implementation. For example, the wireless receiving clock of the master glasses part may be triggered by the first reference signal, and the second reference signal may be triggered after the time T3 elapses according to the count of the wireless receiving clock of the slave glasses part and output to the slave glasses partThe display screen of (1).

Fig. 4(b) shows another schematic diagram of the left eyeglass portion and the right eyeglass portion synchronously displaying video data based on the first reference signal and the second reference signal, respectively, according to the embodiment of the present application. Similar to fig. 4(a), it is still assumed that t is triggered by the first reference signal of the primary spectacle portion ₁ The time and t of the slave glasses part triggering the second reference signal based on the first reference signal ₂ The time differences are T3, in other embodiments, the processing part of the slave glasses part can be at T ₂ T after T4 time period after time ₃ At the moment, the received video data is written into a frame image buffer in a display screen of the slave glasses part, and the processing part of the master glasses part triggers t at the first reference signal ₁ After a time period T2, the received video data is written into the frame image buffer in the display screen of the master glasses part, and as can be seen from fig. 4(b), when T2, T3 and T4 are set to satisfy the relationship of T2 ═ T3+ T4, the master glasses part and the slave glasses part can be synchronized when writing the video data into the frame image buffers of the respective display screens, and the display screen of the master glasses part and the display screen of the slave glasses part can synchronously display the video data in the respective frame image buffers. That is, in the case that the triggering time of the second reference signal is different from the triggering time of the first reference signal by T3 duration, the display screen of the master glasses part may be further configured to write the received video data into the frame image buffer in the display screen of the master glasses part after T2 duration after the triggering of the first reference signal, and the processing part of the slave glasses part may be further configured to write the received video data into the frame image buffer in the display screen of the slave glasses part after T4 duration after the triggering of the second reference signal, where T2 is the sum of T4 and T3, so that the display screen of the master glasses part and the display screen of the slave glasses part may write the video data into the respective frame image buffers separately but synchronously.

Fig. 5(a) shows still another schematic diagram of the left and right eyeglass portions synchronously displaying video data based on the first reference signal and the second reference signal, respectively, according to an embodiment of the present application. It should be noted that FIG. 5 shows a schematic view of a display device(a) Based on FIG. 4(b), t in FIG. 5(a) ₁ 、t ₂ 、t ₃ And T2, T3, T4 and the like have the same meanings as those of the same reference numerals in FIG. 4 (b).

As shown in FIG. 5(a), in some embodiments, the display screen of the main glasses part may also use the video data in the frame image buffer to flush t of the current screen ₀ T of duration T1 before time ₁ And triggering the first reference signal at any time, and outputting the first reference signal to a processing part of the main glasses part. That is, the display screen of the primary eyeglass portion may be further configured to trigger the first reference signal at a time T1 duration before the current screen is swiped over and output the first reference signal to the processing portion of the primary eyeglass portion. By setting the time for triggering the first reference signal by the display screen of the main glasses part as above, the undesirable screen cutting phenomenon generated when the display screen of the main glasses part utilizes the video data in the respective frame image buffer to screen. The following describes in detail a screen brushing timing sequence of the display screen of the main glasses part according to the embodiment of the present application, which is shown in fig. 5 (b).

For example only, a rising edge of the TE signal may be used as the first reference signal according to embodiments of the present application, for example. As mentioned above, the TE signal is used to inform the processing unit of the timing for writing data into the frame image buffer according to the timing for reading and displaying (i.e. refreshing) the data in the frame image buffer, so that the display screen can avoid the conflict caused by the processing unit writing data to the same position when the display screen reads and displays the data in the frame image buffer by properly arranging the TE signal and the timing for refreshing the screen itself (such conflict may cause the screen-cut phenomenon), and meanwhile, the screen-cut phenomenon caused by the replacement of the data in the frame image buffer during the refreshing process of the display screen can be avoided.

Fig. 5(b) illustrates a display screen of the main glasses section as an example. In fig. 5(b), it is assumed that the time point at which the scanning display period of the display panel starts is the falling edge of the TE signal, and the low level period of the TE signal is the scanning display period of the display panel, and during this period, the display panel reads the frame image bufferAnd (3) displaying the data in the memory (namely, refreshing the screen), and controlling to pull up the level of the TE signal when the screen refreshing of the display screen is finished, wherein the screen refreshing process is a non-scanning display period of the display screen during the high level period of the TE signal as shown by a solid line 502 in the figure, namely, the display screen is not refreshed during the period. And the first reference signal may be set in association with a screen-swiping signal (falling edge of TE signal) of the display screen, and the processing portion writes data to the frame image buffer based on the first reference signal, the writing process of the data being shown by a dotted line 501 in the figure. In fig. 5(b), the time when the display screen of the main glasses part is flushed (i.e., the rising edge of the TE signal) is marked as t ₀ Marking the time corresponding to the first reference signal as t ₁ The start time of writing data into the frame image buffer by the processing unit of the main glasses unit is marked as t ₃ 。

Taking scanning display period 1 as an example, the first reference signal is triggered based on the rising edge of the TE signal, and at the same time, the processor starts to write the data of a new frame to the frame image buffer, i.e. t ₃ And t ₀ And t ₁ And (6) overlapping. Under normal conditions, as long as the writing speed shown by the dashed line 501 is faster than the reading speed shown by the solid line 502, it can be ensured that the dashed line 501 and the solid line 502 do not intersect, i.e., the screen blooming or the screen cut phenomenon is not generated. However, consider the case shown in fig. 4(b), namely: t triggered by the first reference signal by the processing part of the main glasses part ₁ T after T2 time period after time ₃ At the moment, the received video data is written into a frame image buffer in the display screen of the main glasses part, t ₃ 、t ₀ And t ₁ The timing relationship of the three is shown in the scanning display period 1 in FIG. 5(b), in this case, the TE still rises (t) ₀ Time) triggering the first reference signal, then, due to the existence of the time duration of T2, the buffer write delay may intersect with the dashed line 501 and the solid line 502 at a certain time, for example, at point X in fig. 5(b), which may not only cause screen splash, but also may affect the screen cut phenomenon caused by the switching of new and old data since the screen is refreshed with the previous frame data before the intersection point X and with the updated new data after the intersection point XThe user experiences wearing smart glasses.

In some embodiments, the first reference signal may be triggered by the display screen of the primary eyewear portion at a time T1 hours before the current screen is swiped through and output to the processing portion of the primary eyewear portion. That is, the display screen of the primary eyeglass portion may be further configured to trigger the first reference signal at a time T1 duration before the current screen is swiped over and output the first reference signal to the processing portion of the primary eyeglass portion. As shown in FIG. 5(b), in the scanning display period 2, the display screen of the main glasses part is at t ₀ At all times the current screen is refreshed, e.g. t which will trigger the first reference signal ₁ Time is set at t ₀ A time of a duration of T1 before the time, so that the processing section of the main eyeglass section can always be caused to start writing T of data by the cooperative arrangement of T1 and T2 ₃ The time is not later than the start time (i.e. the falling edge of the TE signal) of the reading of the buffer data shown by the solid line 502 in the scanning display period 3, that is, it can always be ensured that the dotted line 501 and the solid line 502 do not intersect, and the speed of updating the data in the buffer is faster than the screen refreshing speed of the display screen in the current scanning display period, so that the screen blooming or screen cutting phenomenon is not generated. Assuming that the timings of writing data into the frame image buffer by the master and slave glasses sections adopt the timing shown in fig. 4(a), the broken line 501 and the solid line 502 are guaranteed to be disjoint as long as T1 is greater than T3. Therefore, for the main glasses part, by associating with T2 and appropriately setting the time length of T1, the phenomenon of screen blooming or screen cut of the display screen of the main glasses part can be effectively avoided.

Further, as mentioned above, the processing unit of the master glasses part transmits the first reference signal or the third reference signal triggered based on the first reference signal to the processing unit of the slave glasses part, so that the processing unit of the slave glasses part may generate a fourth reference signal based on the first reference signal or the third reference signal, and transmit the fourth reference signal to the display screen of the slave glasses part, and cause the display screen of the slave glasses part to perform screen refreshing based on the fourth reference signal, wherein the fourth reference signal may be the same signal as the second reference signal or a signal with a certain time delay relationship cooperatively arranged with the second reference signal. In the process, the screen refreshing signal of the display screen of the master glasses part and the screen refreshing signal of the slave glasses part can be kept synchronous by adjusting the time delay or the advance between the reference signals, namely, synchronous screen refreshing of the left display screen and the right display screen is realized. Furthermore, through the adjustment of the time sequence relation of each signal, the relative relation between each signal and the relative relation between the signals corresponding to the main glasses part can be kept consistent in the screen brushing time sequence of the display screen and the writing time sequence of the frame image buffer of the auxiliary glasses part, so that the screen blooming or screen cutting phenomenon cannot occur necessarily in the auxiliary glasses part when the main glasses part can ensure that the screen blooming or screen cutting phenomenon cannot occur. Furthermore, in some embodiments, if there is a fixed time delay between the time when the display screens of the left and right glasses portions start to be swiped, for example, a time interval of one line is needed, the time sequence between the signals (for example, the values of T2 and T4 in fig. 5 (a)) can be adjusted, so that synchronous screen swiping of the display screens of the two glasses portions can still be ensured.

Through the process, on the basis that the main glasses part and the auxiliary glasses part can synchronously write the video data into respective frame image buffers (data synchronization), synchronous screen refreshing (display synchronization) of the display screens of the glasses parts is further realized, so that the video or the image on the display screens of the left and the right glasses parts has stronger stereoscopic impression, the picture is more natural and real, and the wearing experience of a user is greatly improved.

In addition, the display method for the wireless smart glasses according to the embodiment of the present application may further include providing a DLNA module in each of the left and right glasses portions, wherein a DLNA protocol adopted by the DLNA module is first proposed by sony, intel, microsoft, etc., and is generally called DIGITAL LIVING NETWORK ALLIANCE, which is intended to solve the interconnection between a wireless NETWORK and a wired NETWORK, such as a wireless NETWORK and a wired NETWORK, between a computer and other electronic products, such as a mobile phone and a tablet.
