Description

Binocular display method and binocular display device Technical Field

[0001] The present application relates to the field of display devices, and in particular to a binocular display method and a binocular display device. Background Art

[0002] AR (Augmented Reality) glasses are available in two types: binocular display and monocular display. Binocular display AR glasses generally have independent display modules on the left and right sides for imaging. Usually, the user's mobile phone sends the image information to be displayed in the AR glasses to one of the display modules, and then the image information is transmitted between the two display modules to ensure that the imaging of the left and right display modules matches.

[0003] It should be noted that only when the left and right images are synchronized can the user's eyes process the combined image normally after receiving the image. However, when AR glasses are currently imaging, there is often a certain delay between the left and right images, which affects the user experience. Therefore, how to synchronize the imaging of the two display modules is an important issue to improve the user experience.

[0004] On the other hand, some AR glasses currently on the market use a solution of setting up data cables between the two display modules to achieve synchronous imaging. In order to make the frame structure cover the data cables, the thickness and structure of the glasses frame itself will be greatly increased, resulting in problems such as obstructed field of view and cumbersome structure.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a binocular display method and a binocular display device, which aim to avoid the situation where the time difference between the imaging of the two display modules causes the images displayed by the user's viewing device to be unable to be normally combined, and achieve left and right imaging synchronization of the binocular display device, thereby improving the user experience.

[0007] In a first aspect, an embodiment of the present application provides a binocular display method, which is applied to a binocular display device, wherein the binocular display device includes a first display module and a second display module, and the first display module and the second display module are wirelessly connected. The method includes:

[0009] configuring the first image information on the first display module, and configuring the second image information on the second display module;

[0010] The first display module and the second display module are controlled to display image information synchronously, wherein the first display module displays the first image information and the second display module displays the second image information.

[0011] In a second aspect, an embodiment of the present application provides a binocular display device, the binocular display device comprising a first display module and a second display module wirelessly connected to the first display module;

[0012] The binocular display device is further provided with a controller, which is used to control the binocular display device to execute any binocular display method provided in the embodiments of the present application.

[0013] In summary, the embodiments of the present application provide a binocular display method and a binocular display device, wherein the binocular display method is applied to a binocular display device, the binocular display device includes a first display module and a second display module, and the first display module and the second display module are wirelessly connected, the method includes: receiving first binocular image information, the first binocular image information includes first image information for display on the first display module and second image information for display on the second display module; configuring the first image information on the first display module, and configuring the second image information on the second display module; controlling the first display module and the second display module to synchronously display image information, the first display module displays the first image information, and the second display module displays the second image information, thereby avoiding the time difference in imaging between the two display modules, resulting in the image displayed by the user viewing the device cannot be normally combined, so as to achieve left and right imaging synchronization of the binocular display device and improve the user experience.

[0045] As shown in FIG. 3 and FIG. 4 , in some embodiments, the binocular display device 100 further includes a frame assembly 170 , an optical waveguide lens 130 , and a power supply assembly 140 .

[0046] Specifically, the frame assembly 170 is at least used to provide wearing support, and the first display module 110 and the second display module 120 are installed on the frame assembly 170; the optical waveguide lens 130 is installed on the frame assembly 170, and the optical waveguide lens 130 is formed with a coupling-in grating area 133 and an output-out grating area 134, and the coupling-in grating area 133 is arranged opposite to the first display module 110 and the second display module 120, wherein the image signal input to the coupling-in grating area 133 is output from the output-out grating area 134 through the optical waveguide lens 130; the power supply assembly 140 is installed on the frame assembly 170, and is used to power the first display module 110 and the second display module 120.

[0047] It should be noted that the binocular display device 100 is, for example, AR glasses, which the user can wear through the frame assembly 170 of the binocular display device 100, and all other components of the binocular display device 100 except the frame assembly 170 can be installed in the frame assembly 170.

[0048] In some embodiments, the light waveguide lens 130 includes a first lens assembly 131 and a second lens assembly 132 disposed on opposite sides of the frame assembly 170. When a user wears the binocular display device 100, the out-coupling grating area 134 faces the user's eyes, and the image signals input from the first display module 110 and the second display module 120 to the in-coupling grating area 133 are output from the out-coupling grating area 134 through the light waveguide lens 130 and incident on the user's field of view.

[0049] In other embodiments, the optical waveguide lens 130 includes an integrated lens disposed on the frame assembly 170. When the user wears the binocular display device 100, the integrated lens is located in front of the user's line of sight, and the outcoupling grating area 134 is located on the integrated lens.

[0050] As shown in Figures 3 and 4, specifically, a first out-coupling grating region and a second in-coupling grating region are formed on the first lens assembly 131, and the first out-coupling grating region is disposed opposite the first display module 110. A first out-coupling grating region and a second in-coupling grating region are formed on the first lens assembly 131, and the second out-coupling grating region is disposed opposite the second display module 120. When a user wears the binocular display device 100, the first out-coupling grating region and the second out-coupling grating region are respectively opposite the user's eyes. The image signal input from the first display module 110 to the first in-coupling grating region 133 is output from the first out-coupling grating region through the optical waveguide lens 130. Similarly, the image signal input from the second display module 120 to the second in-coupling grating region is output from the second out-coupling grating region through the optical waveguide lens 130. The image signals output from the first out-coupling grating region and the second out-coupling grating region are incident on the user's field of view.

[0051] In some embodiments, the binocular display device 100 provided in the embodiment of the present application is further provided with a sensor component 150 for detecting the posture of the device itself or the wearing condition of the user.

[0052] Exemplarily, the sensor component 150 includes, but is not limited to, a gyroscope, a contact sensor, a G-sensor (gravity sensor), a microphone sensor, a light sensor, a proximity sensor, a camera, a Tof sensor, etc., wherein the gyroscope is used to detect the displacement and rotation of the binocular display device 100. Exemplarily, the sensor component 150 includes, but is not limited to, a proximity sensor, which is used to detect the user's wearing condition.

[0053] In some embodiments, the sensor component 150 is connected to the first display module 110 , and the sensor component 150 is used to detect the posture information of the binocular display device 100 and send the posture information to the first display module 110 .

[0054] In other embodiments, the sensor component 150 is connected to the second display module 120 , and the sensor component 150 is used to detect the posture information of the binocular display device 100 and send the posture information to the second display module 120 .

[0055] In some other embodiments, the sensor component 150 is connected to the main control component 160 , and the sensor component 150 is used to detect the posture information of the binocular display device 100 and send the posture information to the main control component 160 .

[0056] In the above embodiment, after at least one of the first display module 110, the second display module 120 and the main control component 160 obtains the posture information and the image information to be compensated, it is also used to perform image compensation on the image information to be compensated according to the posture information, and display the compensated image, or configure the compensated image to the first display module 110 and / or the second display module 120 for display.

[0057] The image information to be compensated includes but is not limited to the first binocular image information, the first image information and the second image information, and the first binocular image information includes the first image information and the second image information.

[0058] In some embodiments, the computing capability of the first control component 112 in the first display module 110 is greater than that of the second control component 122 in the second display module 120 , that is, the first control component 112 is a master chip and the second control component 122 is a slave chip.

[0059] Furthermore, for the sensor component 150, when the sensor component 150 includes a low-latency sensor, such as a gyroscope, a G-Sensor, a camera, etc., the sensor component 150 is set on a side close to the first display module 110 and connected to the first display module 110. The first display module 110 with stronger computing power performs image compensation on the image information to be compensated according to the posture information, so that the display of the compensated image is triggered faster and with less delay, further improving the user's viewing experience.

[0060] On the other hand, when the sensor component 150 includes a high-latency sensor, such as a microphone sensor, a proximity sensor, etc., since the low latency requirement for such sensors is not great, the sensor component 150 can be placed on a side close to the second display module 120 and connected to the second display module 120, and the second display module 120 performs image compensation on the image information to be compensated based on the posture information.

[0061] Please refer to FIG. 6 , which is a flowchart illustrating the steps of a binocular display method provided in one embodiment of the present application.

[0062] The embodiment of the present application further provides a binocular display method, and the binocular display method of the embodiment of the present application is applied to the binocular display device 100.

[0063] It should be noted that the binocular display device 100 includes but is not limited to AR glasses with binocular display or other electronic devices capable of binocular display. The following describes a specific implementation of the binocular display method applied to the binocular display device 100 in conjunction with the binocular display device 100 provided in an embodiment of the present application.

[0064] As shown in FIG6 , the binocular display method specifically includes the following steps S1-S3.

[0065] Step S1 : receiving first binocular image information, where the first binocular image information includes first image information for display on the first display module 110 and second image information for display on the second display module 120 .

[0066] Specifically, the binocular display device 100 first receives the first binocular image information, wherein the first binocular image information can be image information sent by the terminal device 200 to the binocular display device 100, or it can be image information generated by the binocular image display device based on the device's own posture or the user's wearing condition.

[0067] Exemplarily, the first binocular image information includes first image information and second image information, wherein the first image information and the second image information may be the same image information, that is, when the user uses the binocular display device 100, the two display modules display the same image information; the first image information and the second image information may also be different image information.

[0068] As shown in Figures 3 and 4, illustratively, the binocular image display device detects the device's own posture or the user's wearing condition through the sensor component 150, and sends the posture information of the binocular image display device or the user's wearing condition to the binocular image display device.

[0069] In some embodiments, receiving the first binocular image information specifically involves controlling one of the first display module 110 and the second display module 120 to obtain the first binocular image information.

[0070] It should be noted that the binocular display device 100 includes at least a first display module 110 and a second display module 120 , and the first display module 110 and the second display module 120 are directly connected to each other via wireless communication.

[0071] Specifically, from the perspective of controlling the imaging of the two display modules, generally only one of the first display module 110 and the second display module 120 is connected to the terminal device 200 and / or the sensor component 150 to obtain binocular image information, and then the corresponding image information in the binocular image information is sent to the other one of the first display module 110 and the second display module 120.

[0072] In other embodiments, the binocular display device 100 includes a first display module 110 and a second display module 120, and also includes a main control component 160 wirelessly connected to both the first display module 110 and the second display module 120. Receiving the first binocular image information specifically controls the main control component 160 to obtain the first binocular image information.

[0073] Specifically, the main control component 160 is connected to the terminal device 200 and / or the sensor component 150 to obtain binocular image information, and then sends the corresponding image information in the binocular image information to the first display module 110 and the second display module 120.

[0074] Step S2 : configuring the first image information on the first display module 110 , and configuring the second image information on the second display module 120 .

[0075] It should be understood that the first image information is used to be displayed on the first display module 110, and the second image information is used to be displayed on the second display module 120. Therefore, after receiving the first binocular image information, the first image information needs to be configured on the first display module 110 and the second image information needs to be configured on the second display module 120.

[0076] As shown in FIG3 , in some embodiments, the first display module 110 is configured to receive first binocular image information. In step S2 , configuring the second image information on the second display module 120 includes controlling the first display module 110 to transmit the second image information to the second display module 120 .

[0077] Furthermore, in step S2, configuring the first image information on the first display module 110 includes: controlling the first display module 110 to determine the first image information from the first binocular image information, and temporarily storing the first image information in the first display module 110, so that the first display module 110 outputs the first image information at a target time, wherein the target time is after the second image information is configured on the second display module 120.

[0078] From the perspective of controlling the imaging of the two display modules, generally only one of the first display module 110 and the second display module 120 is connected to the terminal device 200 or the sensor component 150 to obtain binocular image information, and then the corresponding image information in the binocular image information is sent to the other one.

[0079] In the embodiment of the present application, the specific process of the binocular display method is described in detail by taking the first display module 110 as being used to receive the first binocular image information. However, the present application is not limited to the scenario in which the first display module 110 is configured to receive the first binocular image information.

[0080] In some embodiments, controlling the first display module 110 to transmit the second image information to the second display module 120 includes:

[0081] Determining a first idle time slot in a wireless transmission channel between the first display module 110 and the second display module 120;

[0082] The first display module 110 is controlled to send the second image information to the second display module 120 in the first idle time slot.

[0083] It should be noted that based on the wireless communication connection between the first display module 110 and the second display module 120, a wireless transmission channel that can be used to transmit data is formed between the first display module 110 and the second display module 120, and the first idle time slot for transmitting the second image information can be determined from the wireless transmission channel, wherein the first idle time slot refers to a period of time when the transmission channel is idle and can be used to transmit data, that is, a time slot.

[0084] In some embodiments, determining a first idle time slot in a wireless transmission channel between the first display module 110 and the second display module 120 includes:

[0085] Obtaining a data transmission time required for performing a preset data transmission via a wireless transmission channel;

[0086] The first display module 110 is controlled to determine a first idle time slot from the wireless transmission channel, wherein a time length of the first idle time slot is greater than or equal to a data transmission time.

[0087] Specifically, performing the preset data transmission specifically refers to transmitting the first image information or the second image information via a wireless transmission channel. The data transmission time can be calculated based on the transmission rate of the wireless transmission channel and the amount of image information data. After obtaining the data transmission time, the first display module 110 is controlled to determine a first idle time slot from the wireless transmission channel and apply for the first idle time slot to transmit the second image information to the second display module 120 within the first idle time slot.

[0088] It should be noted that the length of the first idle time slot is greater than or equal to the data transmission time to ensure that the first display module 110 has sufficient time to send the second image information to be displayed on the second display module 120 to the second display module 120, so as to avoid affecting the first display module 110 and the second display module 120 from being unable to display image information synchronously.

[0089] In some embodiments, obtaining a data transmission time required for performing a preset data transmission through a wireless transmission channel includes:

[0090] Obtaining the transmission rate of the wireless transmission channel;

[0091] The data transmission time is determined according to the transmission rate of the wireless transmission channel and the data volume of the preset data, wherein the preset data includes the first image information and / or the second image information.

[0092] It should be noted that the transmission rate of the wireless transmission channel can be determined based on the wireless protocol on the wireless transmission channel, that is, the inherent transmission rate of the wireless transmission channel, or it can be determined by controlling the first display module 110 to transmit a set of test data to the second display module 120 through the wireless transmission channel, based on the time to complete the transmission and the amount of test data.

[0093] By determining the data transmission time according to the transmission rate and the amount of preset data, the time length of the first idle time slot can be accurately determined to ensure that the first display module 110 has enough time to send the second image information displayed on the second display module 120 to the second display module 120.

[0094] In some implementations, determining a first idle time slot from a wireless transmission channel includes:

[0095] Extracting at least one first candidate time slot from the wireless transmission channel that is in an idle state and has a duration greater than or equal to the data transmission time, wherein different first candidate time slots have different data transmission time points during the data transmission process between the first display module 110 and the second display module 120;

[0096] A first idle time slot that meets a preset data transmission condition is selected from the first candidate time slots.

[0097] Specifically, the wireless transmission channel has a time axis corresponding thereto, and the first candidate time slot refers to a period of time that is in an idle state on the time axis and has a time length greater than or equal to the data transmission time.

[0098] It should be noted that any time period on the timeline can be in an idle state or an active state. The first candidate time slot is one or more time slots that can be occupied by the first display module 110 and used to transmit data to the second display module 120. Therefore, the first idle time slot can be selected from the first candidate time slots. When the first display module 110 transmits data to the second display module 120 in the first idle time slot, the first idle time slot is in an active state.

[0099] In some embodiments, the first idle time slot is a first candidate time slot with the earliest data transmission time point during the process of data transmission from the first display module 110 to the second display module 120 via the wireless transmission channel;

[0100] Alternatively, the first idle time slot is the first candidate time slot with the shortest data transmission time during the process of data transmission from the first display module 110 to the second display module 120 through the first candidate time slot.

[0101] Specifically, the preset data transmission condition may refer to the earliest time point of data transmission. Therefore, the first idle time slot selected from the first candidate time slots is the first candidate time slot with the earliest time point of data transmission during the process of data transmission from the first display module 110 to the second display module 120 through the wireless transmission channel.

[0102] On the other hand, when the time point of data transmission cannot be determined or an abnormality occurs in the wireless transmission channel, the preset data transmission condition may refer to the shortest data transmission time. Therefore, the first idle time slot selected from the first candidate time slots is the first candidate time slot with the shortest data transmission time during the process of data transmission from the first display module 110 to the second display module 120 via the wireless transmission channel.

[0103] It should be understood that the first candidate time slot is first determined by combining the time length and whether it is in an idle state, and then the first idle time slot that meets the preset data transmission conditions is screened out, thereby ensuring that the transmission effect is stable when the first display module 110 transmits data to the second display module 120 in the first idle time slot, and ensuring that the first display module 110 has sufficient time to send the second image information displayed on the second display module 120 to the second display module 120.

[0104] In some embodiments, controlling the first display module 110 and the second display module 120 to synchronize the time slot information corresponding to the first idle time slot includes:

[0105] The first display module 110 is controlled to generate a time slot feedback according to the time slot information of the first idle time slot, and output the time slot feedback to the second display module 120, so that the second display module 120 performs a time slot information synchronization operation according to the time slot feedback.

[0106] Furthermore, after determining the first idle time slot, the method further includes:

[0107] The first display module 110 and the second display module 120 are controlled to synchronize time slot information corresponding to the first idle time slot.

[0108] It should be understood that after determining the first idle time slot, it is also necessary to control the first display module 110 and the second display module 120 to synchronize the time slot information corresponding to the first idle time slot, so that the first display module 110 and the second display module 120 can transmit image information at mutually determined time nodes, ensuring that the first display module 110 and the second display module 120 can display image information synchronously.

[0109] Specifically, the time slot information corresponding to the first idle time slot is, for example, the timestamp or serial number of the first idle time slot on the corresponding time axis. The first display module 110 and the second display module 120 synchronize the corresponding timestamps or serial numbers so that the first display module 110 and the second display module 120 can transmit image information at mutually determined time nodes.

[0110] In some embodiments, controlling the first display module 110 and the second display module 120 to synchronize the time slot information corresponding to the first idle time slot includes:

[0111] The first display module 110 is controlled to generate a time slot feedback according to the time slot information of the first idle time slot, and output the time slot feedback to the second display module 120, so that the second display module 120 performs a time slot information synchronization operation according to the time slot feedback.

[0112] Specifically, the second display module 120 performs the time slot information synchronization operation, which specifically includes: the second display module 120 analyzes the time slot feedback, obtains the time slot information of the first idle time slot, and realizes the synchronization of the time slot information.

[0113] Furthermore, the second display module 120 can also generate corresponding response information based on the acquired time slot information and send it to the first display module 110. Under the condition that the time slot feedback matches the response information, the first display module 110 can confirm that the first display module 110 and the second display module 120 have completed the synchronization of the time slot information corresponding to the first idle time slot to continue subsequent data transmission.

[0114] As shown in FIG4 , in some embodiments, the binocular display device 100 further includes a main control component 160 wirelessly connected to the first display module 110 and the second display module 120. The main control component 160 is configured to receive the first binocular image information. In step S2, the first image information is configured on the first display module 110, and the second image information is configured on the second display module 120, including:

[0115] The control main control component 160 transmits the first image information to the first display module 110 , and transmits the second image information to the second display module 120 .

[0116] In some embodiments, controlling the main control component 160 to transmit the first image information to the first display module 110 and to transmit the second image information to the second display module 120 includes:

[0117] Determining a second idle time slot based on a first transmission channel between the main control component 160 and the first display module 110 and a second transmission channel between the main control component 160 and the second display module 120, wherein both the first transmission channel and the second transmission channel are in an idle state during the second idle time slot;

[0118] The control main control component 160 sends the first image information to the first display module 110 and sends the second image information to the second display module 120 in the second idle time slot.

[0119] Specifically, based on the wireless communication connection between the main control component 160 and the first display module 110, and the wireless communication connection between the main control component 160 and the second display module 120, the main control component 160 and the first display module 110 form a first transmission channel that can be used to transmit data. Similarly, the main control component 160 and the second display module 120 form a second transmission channel that can be used to transmit image information.

[0120] Based on this, a second idle time slot for transmitting image information can be determined based on the corresponding time axes of the first and second transmission channels and information about whether they are in an idle state. The second idle time slot refers to a period of time when both the first and second transmission channels are idle and available for data transmission. The main control component 160 then controls the first image information to be transmitted to the first display module 110 and the second image information to be transmitted to the second display module 120 during the second idle time slot.

[0121] It should be noted that the second idle time slot is determined based on both the first transmission channel and the second transmission channel to ensure that the main control component 160 has sufficient time to transmit the corresponding image information to the first display module 110 and the second display module 120, and to ensure that the first display module 110 and the second display module 120 can display the image information synchronously without affecting the imaging effect.

[0122] In some embodiments, determining the second idle time slot based on the first transmission channel between the main control component 160 and the first display module 110 and the second transmission channel between the main control component 160 and the second display module 120 includes:

[0123] determining a third idle time slot in the first transmission channel;

[0124] determining a fourth idle time slot in the second transmission channel;

[0125] A second idle time slot is determined according to the third idle time slot and the fourth idle time slot, wherein the second idle time slot corresponds to an overlapping time period of the third idle time slot and the fourth idle time slot.

[0126] In some implementations, determining a third idle time slot in the first transmission channel includes:

[0127] Obtaining a first transmission time required for performing preset data transmission through a first transmission channel;

[0128] A third idle time slot is determined from the first transmission channel, wherein a time length of the third idle time slot is greater than or equal to the first transmission time.

[0129] Specifically, performing the preset data transmission specifically refers to transmitting the first image information or the second image information via the first transmission channel. The first transmission time can be calculated based on the transmission rate of the first transmission channel and the data volume of the image information. After obtaining the data transmission time, the control main control component 160 determines a third idle time slot from the first transmission channel.

[0130] It should be noted that the length of the third idle time slot is greater than or equal to the data transmission time, so as to ensure that the main control component 160 has sufficient time to send the corresponding image information to the second display module 120 .

[0131] In some embodiments, obtaining a first transmission time required for performing a preset data transmission through a first transmission channel includes:

[0132] Obtaining a transmission rate of a first transmission channel;

[0133] The first transmission time is determined according to a transmission rate of the first transmission channel and a data volume of preset data, wherein the preset data includes the first image information and / or the second image information.

[0134] It should be noted that the transmission rate of the first transmission channel can be determined based on the wireless protocol of the first transmission channel between the main control component 160 and the first display module 110, that is, the inherent transmission rate of the first transmission channel, or it can be determined by controlling the main control component 160 to transmit a set of test data to the first display module 110 through the first transmission channel, based on the time to complete the transmission and the amount of test data.

[0135] By determining the data transmission time according to the transmission rate and the amount of preset data, the time length of the third idle time slot can be accurately determined to ensure that the main control component 160 has enough time to send the first image information displayed on the first display module 110 to the first display module 110.

[0136] In some implementations, determining a third idle time slot from the first transmission channel includes:

[0137] Extracting at least one second candidate time slot from the first transmission channel that is in an idle state and has a time length greater than or equal to the first transmission time, wherein different second candidate time slots have different time points of data transmission during the data transmission process of the main control component 160;

[0138] A third idle time slot that meets a preset data transmission condition is selected from the second candidate time slots.

[0139] Specifically, the first transmission channel has a time axis corresponding thereto, and the second candidate time slot refers to a period of time that is in an idle state on the time axis and has a time length greater than or equal to the data transmission time.

[0140] It should be noted that any time period on the timeline can be in an idle state or an active state. The second candidate time slot is one or more time slots that can be occupied by the main control component 160 and used to transmit data to the first display module 110. Therefore, the third idle time slot can be selected from the second candidate time slots. When the main control component 160 transmits data to the first display module 110 in the third idle time slot, the third idle time slot is in an active state.

[0141] In some embodiments, the third idle time slot is the second candidate time slot with the earliest data transmission time point during the process of the main control component 160 transmitting data to the first display module 110 through the first transmission channel;

[0142] Alternatively, the third idle time slot is the second candidate time slot with the shortest data transmission time during the process of the main control component 160 transmitting data to the first display module 110 through the second candidate time slot.

[0143] Specifically, the preset data transmission condition may refer to the earliest time point of data transmission. Therefore, the third idle time slot selected from the second candidate time slot is the second candidate time slot with the earliest time point of data transmission during the process of data transmission from the main control component 160 to the first display module 110 through the first transmission channel.

[0144] On the other hand, when the time point of data transmission cannot be determined or an abnormality occurs in the first transmission channel, the preset data transmission condition may refer to the shortest data transmission time. Therefore, the third idle time slot selected from the second candidate time slot is the second candidate time slot with the shortest data transmission time during the process of data transmission from the main control component 160 to the first display module 110 through the wireless transmission channel.

[0145] It should be understood that the second candidate time slot is first determined by combining the time length and whether it is in an idle state, and then the third idle time slot that meets the preset data transmission conditions is screened out, thereby ensuring that the main control component 160 has a stable transmission effect when transmitting data to the first display module 110 in the third idle time slot, and ensuring that the main control component 160 has sufficient time to send the first image information displayed on the first display module 110 to the first display module 110.

[0146] Similarly, the specific steps and procedures for determining the fourth idle time slot in the second transmission channel may refer to the embodiment for determining the third idle time slot in the first transmission channel, and are not described in detail here.

[0147] After determining the third idle time slot in the first transmission channel and the fourth idle time slot in the second transmission channel, a second idle time slot is determined based on the third idle time slot and the fourth idle time slot. It should be understood that the second idle time slot corresponds to the overlapping time period of the third idle time slot and the fourth idle time slot, that is, both the first transmission channel and the second transmission channel are idle during the second idle time slot.

[0148] Based on this, the overlapping time period of the third idle time slot and the fourth idle time slot can be used as the second idle time slot, or a sub-time period in the overlapping time period of the third idle time slot and the fourth idle time slot can be used as the second idle time slot.

[0149] It should be noted that when determining the second idle time slot based on the third idle time slot and the fourth idle time slot, it is also necessary to ensure that: the time length of the second idle time slot is greater than or equal to the time for the control component to transmit data to the first display module 110 and the second display module 120, so as to ensure that the main control component 160 has sufficient time to send the corresponding image information to the first display module 110 and the second display module 120.

[0150] In some embodiments, the target display module has a switchable first operating mode and a second operating mode, wherein the communication performance of the target display module in the first operating mode is greater than the communication performance in the second operating mode, and the target display module includes at least one of the first display module 110 and the second display module 120.

[0151] Accordingly, the binocular display method provided in the embodiment of the present application further includes the steps of:

[0152] Before configuring the first image information and the second image information, the current operating mode of the target display module is configured as the first operating mode or the second operating mode according to information attributes of the first binocular image information.

[0153] It should be noted that the communication performance of the target display module in different working modes, that is, the rate of data transmission, is different. When the binocular display device 100 does not need to perform binocular synchronous display, a low-power wireless communication connection, such as BLE communication, will be maintained between the first display module 110 and the second display module 120, and / or between the main control component 160 and the first display module 110, and / or between the main control component 160 and the second display module 120. At this time, the corresponding display module will enter the second working mode. The low-power wireless communication connection is mainly used for synchronization of small data volumes or non-real-time data. When high-speed data transmission or binocular synchronous display is required, a high-speed and high-power transmission channel will be used between the corresponding main control component 160 and / or the display module for wireless communication connection. At this time, the corresponding display module will enter the first working mode.

[0154] Based on this, before configuring the first image information and the second image information, the current operating mode of the target display module is configured as the first operating mode or the second operating mode according to the information attribute of the first binocular image information.

[0155] For example, when the information attribute of the first binocular image information meets the preset attribute condition, it is determined that the binocular display device 100 needs to perform high-speed data transmission or binocular synchronous display, and the current working mode of the target display module is configured as the first working mode.

[0156] To further illustrate, the communication performance of the target display module in the first operating mode is greater than the communication performance in the second operating mode. Accordingly, the power consumption of the target display module in the first operating mode is greater than the power consumption in the second operating mode. Therefore, from the perspective of saving battery power of the binocular display device 100, the main control component 160 only uses a high-speed, high-power transmission channel for wireless communication between the corresponding main control component 160 and / or the display module when high-speed data transmission and / or binocular synchronous display is required.

[0157] Specifically, taking the binocular display method applied to the binocular display device 100, and the binocular display device 100 being AR glasses as an example, the current working mode of the target display module is configured to be the first working mode or the second working mode according to the information attributes of the first binocular image information, and intelligent switching between the two working modes can be achieved to optimize the operating power consumption of the binocular display device 100, and reduce the volume and weight occupied by the battery, making the structural design of the AR glasses lighter.

[0158] In some embodiments, the information attribute includes an information capacity value, and configuring the current operating mode of the target display module to the first operating mode or the second operating mode according to the information attribute of the first binocular image information includes:

[0159] Determining whether the information capacity value of the first binocular image information exceeds a preset value;

[0160] When the information capacity value of the first binocular image information exceeds a preset value, configuring the current working mode of the target display module to the first working mode;

[0161] When the information capacity value of the first binocular image information does not exceed the preset value, the current operating mode of the target display module is configured as the second operating mode.

[0162] Specifically, if the first binocular image information capacity value is greater than a preset value, it is determined that the binocular display device 100 needs to perform high-speed data transmission to ensure synchronous display of the first display module 110 and the second display module 120, and the current working mode of the target display module is configured to the first working mode; conversely, if the first binocular image information capacity value is less than or equal to the preset value, it is determined that the binocular display device 100 can maintain a low-power wireless communication connection, and the current working mode of the target display module is configured to the second working mode.

[0163] Specifically, determining whether the information capacity value of the first binocular image information exceeds a preset value and configuring the operating mode can be performed by the main control component 160, or can be performed by at least one of the first display module 110 and the second display module 120. For example, when performed by the main control component 160, the main control component 160 obtains the first binocular image information and analyzes the first binocular image information to determine whether the information capacity value of the first binocular image information exceeds the preset value. If the information capacity value of the first binocular image information exceeds the preset value, the main control component 160 sends a first indication signal to the target display module to instruct the target display module to configure the current operating mode to the first operating mode. If the information capacity value of the first binocular image information does not exceed the preset value, the main control component 160 sends a second indication signal to the target display module to instruct the target display module to configure the current operating mode to the second operating mode.

[0164] In some embodiments, the method further comprises:

[0165] After the target display module in the second operating mode completes configuring the corresponding image information, the target display module is controlled to switch the second operating mode to the first operating mode.

[0166] Specifically, after the corresponding image information is configured, controlling the target display module to switch from the second working mode to the first working mode can intelligently implement the switching between the two working modes to optimize the operating power consumption of the binocular display device 100 and save power.

[0167] Step S3: controlling the first display module 110 and the second display module 120 to display image information synchronously, wherein the first display module 110 displays the first image information, and the second display module 120 displays the second image information.

[0168] Specifically, the first display module 110 and the second display module 120 may simultaneously display the corresponding image information at the end of the first idle time slot, or may simultaneously display the corresponding image information at a preset time after the end of the first idle time slot.

[0169] In some embodiments, before controlling the first display module 110 and the second display module 120 to synchronously display image information, the method further includes: controlling the first display module 110 and the second display module 120 to synchronize the display time corresponding to the first binocular image information.

[0170] For example, taking the main control component 160 performing the above operation as an example, after determining the second idle time slot, the main control component 160 determines the display time information according to the second idle time slot, and sends the display time information to the first display module 110 and the second display module 120, so that the first display module 110 and the second display module 120 determine the display time corresponding to the first binocular image information according to the display time information.

[0171] Please refer to FIG. 7 , which is a time comparison table of an implementation of a binocular display method provided in an embodiment of the present application.

[0172] As shown in FIG7 , in some embodiments, the first display module 110 is configured to receive the first binocular image information. Accordingly, controlling the first display module 110 and the second display module 120 to synchronously display the image information includes:

[0173] Controlling the first display module 110 to display the first image information at the end of the first idle time slot, and controlling the second display module 120 to display the second image information at the end of the first idle time slot;

[0174] Alternatively, the first display module 110 is controlled to display the first image information at a preset time after the first idle time slot, and the second display module 120 is controlled to display the second image information at a preset time after the first idle time slot.

[0175] Specifically, if the first display module 110 is configured to receive the first binocular image information, control the first display module 110 to send the second image information to the second display module 120 within the first idle time slot, and control the first display module 110 and the second display module 120 to display the first image information and the second image information respectively at the same time node, wherein the time when the first display module 110 and the second display module 120 synchronously display the image information must be after the first idle time slot to ensure that the first display module 110 has sufficient time to send the second image information to the second display module 120, so that the first display module 110 and the second display module 120 can synchronously display matching image information.

[0176] Please refer to FIG8 , which is a time comparison table of another implementation of the binocular display method provided in an embodiment of the present application.

[0177] As shown in FIG8 , in some embodiments, the main control component 160 is configured to receive the first binocular image information. Accordingly, controlling the first display module 110 and the second display module 120 to synchronously display the image information includes:

[0178] Controlling the first display module 110 to display the first image information at the end of the second idle time slot, and controlling the second display module 120 to display the second image information at the end of the second idle time slot;

[0179] Alternatively, the first display module 110 is controlled to display the first image information at a preset time after the second idle time slot, and the second display module 120 is controlled to display the second image information at a preset time after the second idle time slot.

[0180] Similarly, if the main control component 160 is configured to receive the first binocular image information, the main control component 160 is controlled to send the first image information to the first display module 110 and the second image information to the second display module 120 within the second idle time slot, and the first display module 110 and the second display module 120 are controlled to display the first image information and the second image information respectively at the same time node, wherein the time when the first display module 110 and the second display module 120 synchronously display the image information must be after the second idle time slot to ensure that the main control component 160 has enough time to send the corresponding image information, so that the first display module 110 and the second display module 120 can synchronously display matching image information.

[0181] Please refer to FIG. 9 , which is a flowchart illustrating the steps of another binocular display method provided in an embodiment of the present application.

[0182] As shown in FIG9 , in some embodiments, the binocular display method further includes steps S4 to S6 after executing steps S1 to S3:

[0183] Step S4: receiving second binocular image information, the second binocular image information being used to display third image information on the first display module 110 and fourth image information on the second display module 120, the third image information being displayed after the first image information, and the fourth image information being displayed after the second image information;

[0184] Step S5: determining a fifth idle time slot, and configuring the third image information on the first display module 110 and the fourth image information on the second display module 120 within the fifth idle time slot, wherein the fifth idle time slot is after the first idle time slot;

[0185] Step S6: controlling the first display module 110 and the second display module 120 to display image information synchronously, wherein the first display module 110 displays the third image information, and the second display module 120 displays the fourth image information.

[0186] The second binocular image information is image information that the binocular display device 100 needs to display after displaying the first binocular image information, wherein the second binocular image information includes third image information for displaying on the first display module 110 and fourth image information for displaying on the second display module 120.

[0187] Specifically, similar to the first idle time slot, the fifth idle time slot refers to a period of time during which the corresponding transmission channel is idle and available for data transmission. The fifth idle time slot occurs after the first idle time slot. The specific steps for determining the fifth idle time slot can be found in the embodiment for determining the first idle time slot and are not further described here.

[0188] It should be noted that during actual use, the binocular display device 100 may receive multiple binocular image information consecutively. For example, during the process of configuring the first image information and the second image information in the first binocular image information, if the binocular display device 100 receives the second binocular image information, determines that the fifth idle time slot is after the end of the first idle time slot, and then configures the third image information on the first display module 110 and the fourth image information on the second display module 120 within the fifth idle time slot.

[0189] It should be understood that setting the fifth idle time slot after the first idle time slot is intended to ensure that each idle time slot is independent of each other, avoid mutual interference in the process of configuring different image information, and ensure the stability of configuring each image information.

[0190] Furthermore, when the binocular display device 100 receives the nth binocular image information, it determines the corresponding idle gap, and the idle gap corresponding to the nth binocular image information must be after the idle gap corresponding to the (n-1)th binocular image information, where n is an integer greater than or equal to 2.

[0191] In some embodiments, the binocular display device 100 determines a fifth idle time slot after the first idle time slot ends, and configures the third image information on the first display module 110 and the fourth image information on the second display module 120 in the fifth idle time slot.

[0192] In some embodiments, the determined fifth idle time slot must satisfy the following requirement: the time difference between the start node of the fifth idle time slot and the start node of the first idle time slot is greater than a preset configuration time threshold. It should be understood that, under the condition that the time required for the binocular display device 100 to configure the binocular image information is less than or equal to the configuration time threshold, setting the time difference between the start node of the fifth idle time slot and the start node of the first idle time slot to be greater than the preset configuration time threshold ensures that each idle time slot is independent of each other, avoids mutual interference between the processes of configuring different image information, and ensures the stability of the configuration of each image information.

[0193] It should be noted that, taking the binocular display device 100 as AR glasses as an example, when a user wears the AR glasses, since the position of the AR glasses and the human eyes are relatively fixed, when the human head shakes and moves, the image displayed by the AR glasses will also shake and move with the user's head, which makes the user prone to dizziness when reading image information.

[0194] Based on this, in some embodiments, the binocular display method provided by the embodiments of the present application further includes:

[0195] Obtaining the position information of the binocular display device 100;

[0196] The first display module 110 and / or the second display module 120 are controlled to perform image compensation processing on the first image information and the second image information according to the posture information, so that the first display module 110 and the second display module 120 synchronously display the image information after image compensation processing.

[0197] Specifically, when the first display module 110 and / or the second display module 120 performs image compensation processing on the first image information and the second image information based on the posture information, the process specifically includes: determining the displacement and rotation of the binocular display device 100 based on the posture information, calling a preset image compensation algorithm, and performing image compensation processing on the first image information and the second image information based on the displacement, rotation, and image compensation algorithm. The image compensation processing on the first image information and the second image information specifically adjusts the relative position of a single pixel in the image information relative to the entire image based on the displacement and rotation.

[0198] By performing image compensation processing on the first image information and the second image information according to the posture information, the imaging jitter caused by the user walking or shaking his head while wearing the binocular display device 100 can be effectively addressed, thereby avoiding dizziness in the user and achieving better anti-shake and anti-interference effects.

[0199] As shown in FIG. 1 , in some embodiments, the binocular display device 100 further includes a sensing component 150 for acquiring position information of the binocular display device 100 .

[0200] Exemplarily, the posture information includes at least the displacement and rotation of the binocular display device 100 .

[0201] Take the example of the first display module 110 being used to obtain the first binocular image and the first posture information, and the first display module 110 being used to perform image compensation processing on the first image information and the second image information: the first display module 110 is controlled to perform image compensation processing on the first image information and the second image information, and the first display module 110 sends the image-compensated second image information to the second display module 120 within the first idle time slot, so that the first display module 110 and the second display module 120 synchronously display the image information after image compensation processing.

[0202] As shown in FIG3 and FIG4 , in some embodiments, the binocular display method provided by the embodiment of the present application further includes:

[0203] Controlling the first display module 110 to obtain posture information, and controlling the first display module 110 to perform image compensation processing on the first image information according to the posture information;

[0204] The first display module 110 is controlled to send the posture information to the second display module 120 , so that the second display module 120 performs image compensation processing on the second image information according to the posture information.

[0205] Specifically, the first display module 110 is configured to obtain position information, perform image compensation processing on the first image information based on the position information, and transmit the position information and the second image information to the second display module 120, which then performs image compensation processing on the second image information.
