[0043] In related technologies, the main function of wearable display devices is internal display, used to show corresponding information to the user after the user wears the device. However, after the user removes the wearable display device, since the device cannot display externally, the user cannot obtain relevant display information when not wearing the device.

[0044] This invention proposes a control method for a display device 100. This display device 100 can be applied to wearable display devices such as AR glasses and VR glasses. Please refer to... Figures 1 to 3 In one embodiment of the present invention, the display device 100 includes a light-emitting component 10 and an optical component 20. The optical component 20 includes an insertion portion and an exit portion. The two opposite surfaces of the exit portion are respectively provided with a first exit region and a second exit region.

[0045] The optical component 20 is used to transmit light and has an input section for receiving incident light and an output section for projecting light out. The optical component 20 can be configured as an optical waveguide or other optical component with light transmission function. The input and output sections of the optical component 20 can be arranged side by side in the same straight direction, or they can be arranged according to other spatial orientations, which are not limited here.

[0046] The light-emitting component 10 can be configured as a display optical engine. The coupling portion of the optical component 20 is located on the light-emitting path of the display optical engine and is used to receive the light beam emitted by the display optical engine. This allows the light beam emitted by the display optical engine to first enter through the coupling portion and, after being transmitted through the optical component 20, to exit from either of the two opposing surfaces of the coupling portion. The light beam emitted by the light-emitting component 10 toward the coupling portion can be parallel light or diffused light. In one feasible embodiment, the beam emission angle of the light-emitting component 10 is limited to 0° to 10°. Specifically, the angle between the emission direction of the light-emitting component 10 and the normal direction of the substrate 21 is defined as the beam emission angle of the light-emitting component 10. This emission angle can be 0°, 5°, 10°, or any value within 0° to 10°, to ensure that the light beam emitted by the light-emitting component 10 enters the optical component 20 through the coupling portion.

[0047] The internal display beam emitted from the first coupling region can be either parallel or converging light, with an emission angle ranging from 0° to 15°. The internal display beam can be transmitted to the human eye from the coupling grating either as parallel light or as converging light. By configuring the internal display beam as a converging light, it is easier for the beam to couple to the human eye and be received by it. Therefore, the emission angle range of the internal display beam can be limited to 0° to 15°. Specifically, the angle between the emission direction of the internal display beam and the normal direction of the substrate 2121 is defined as the emission angle of the internal display beam. This emission angle can be 0°, 5°, 10°, 15°, or any value within the range of 0° to 15° to ensure the coupling effect of the internal display beam.

[0048] The external display beam emitted from the second coupling region can be either parallel light or diffused light, and the emission angle range of the external display beam is 0° to 35°. The external display beam can be emitted from the coupling grating as parallel light to achieve external projection, or it can be emitted as convergent light to achieve external projection. By configuring the external display beam as convergent light, it is beneficial to increase the projection area of ​​the display device 100100. Therefore, the emission angle range of the external display beam can be limited to 0° to 15°. Specifically, the angle between the emission direction of the external display beam and the normal direction of the substrate 2121 is defined as the emission angle of the external display beam. This emission angle can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, or any value within the range of 0° to 35°, to ensure the coupling effect of the external display beam.

[0049] Specifically, one surface of the optical component 20 is designated as a first surface, and the other surface as a second surface. The coupling portion of the optical component 20 has a coupling area on the first surface, and the coupling portion of the optical component 20 has a first coupling area and a second coupling area on the first and second surfaces, respectively. With this configuration, the optical component 20 can receive incident light through the coupling area of ​​the first surface and transmit the light to the coupling portion. The light then exits through the first coupling area on the first surface as an internal display beam, which is projected inwards by the display device 100. This allows users to directly obtain relevant display information through the internal display beam when wearing a wearable display device. Alternatively, after the light is transmitted to the coupling portion, it can also exit through the second coupling area on the second surface as an external display beam, which is projected outwards by the display device 100. This allows users to directly obtain relevant display information through the external display beam when not wearing a wearable display device.

[0050] In some embodiments, the optical component 20 includes a substrate 21, a coupling grating 22, and two coupling gratings. The coupling grating 22 is disposed on the substrate 21 and is used to form the coupling portion. The two coupling gratings are a first coupling grating 23a and a second coupling grating 23b, which are disposed on opposite surfaces of the substrate 21 to form the first coupling region and the second coupling region, respectively.

[0051] The substrate 21 can be a dielectric waveguide, which is generally planar and has two opposing surfaces. In other embodiments, the substrate 21 can also be cylindrical or other shapes, and the specific implementation can be designed according to the desired product. The material of the substrate 21 can be epoxy resin or other organic materials, or inorganic materials such as heavy flint glass, and is not limited here. A coupling grating 22 is disposed on one side surface of the substrate 21 to form the coupling portion of the optical component 20. The coupling grating 22 can change the incident angle of the incident light entering the interior of the substrate 21, so that the incident angle is greater than or equal to the critical angle, thereby allowing the light to couple into the substrate 21 and undergo total internal reflection within the substrate 21, so as to transmit through the substrate 21 to the coupling portion.

[0052] When light rays coupled into the substrate 21 by the coupling grating 22 strike the coupling grating, their incident angle can be deflected again. For example, the incident angle may be less than the critical angle for total internal reflection. The incident light rays are then transmitted through the substrate 21 and can exit through the coupling grating to form a display beam for human eyes. Therefore, by providing a first coupling grating 23a and a second coupling grating 23b on opposite surfaces of the substrate 21 to form a first coupling region and a second coupling region, the optical component 20 can have opposite display beam emission directions, allowing inner and outer display beams to exit through the two coupling gratings respectively.

[0053] The coupling grating 22 or the coupling grating can be attached to the substrate 21 as a separate optical element, or the structure of the coupling grating 22 or the coupling grating can be formed in the corresponding area of ​​the substrate 21. The first coupling grating 23a and the second coupling grating 23b can be arranged opposite each other in the normal direction of the substrate 21, or the first coupling grating 23a and the second coupling grating 23b can be staggered. The specific implementation can be set according to actual needs and is not limited here.

[0054] Please see Figure 4 In one embodiment of the present invention, the control method of the display device 100 includes the following steps:

[0055] Step S10: Receive control commands.

[0056] The control commands may include one or more of the following: mode selection command, mode switching command, and mode maintenance command. Specific implementations can be customized according to actual needs. For example, the mode selection command may include at least a first control command and a second control command, which correspond to the internal display mode and external display mode settings, respectively. After receiving the first control command, the operating mode of the display device 100 is confirmed to be the internal display mode, allowing light to exit inward from the first coupling area of ​​the coupling portion of the optical component 20. After receiving the second control command, the operating mode of the display device 100 is confirmed to be the external display mode, allowing light to be projected outward from the second coupling area of ​​the coupling portion of the optical component 20.

[0057] Step S20: Confirm the working mode according to the control command. The working mode includes internal display mode and external display mode.

[0058] Step S30: According to the working mode, control the light emitting component 10 to emit light into the coupling part so that the light is emitted from the first coupling area and / or the second coupling area.

[0059] For further information, please refer to [link / reference]. Figure 5 In an embodiment of the present invention, the coupling section includes a first coupling region and a second coupling region. The step of controlling the light emitting component 10 to emit light into the coupling section according to the operating mode, so that the light is emitted from the first coupling region and / or the second coupling region, includes:

[0060] According to the operating mode, the light beam emitted by the light emitting component 10 is controlled to be incident on the first coupling region and / or the second coupling region, so that the light beam is emitted from the first coupling region and / or the second coupling region.

[0061] It should be noted that when the input grating 22 and the output grating satisfy a special correspondence, the light beam emitted from the light-emitting component 10, after passing through the input grating 22 and incident on the substrate 21, can be emitted as a display beam through the corresponding output grating. This special correspondence means that there is a unique correspondence between the grating parameters of the input grating 22 and the output grating, such as the grating period, duty cycle, slot depth, and sidewall tilt angle. Only when this unique correspondence is satisfied can the output grating normally emit the light beam modulated by the corresponding input grating 22.

[0062] Therefore, it can be understood that the technical solution of the present invention may involve providing a coupling grating 22 at the coupling portion of the optical component 20, and the coupling grating 22 includes a first coupling portion 221 and a second coupling portion 222, wherein the grating parameters of the first coupling portion 221 and the second coupling portion 222 are different, so as to satisfy a special correspondence with the first coupling grating 23a and the second coupling grating 23b of the coupling portion, respectively. Alternatively, the technical solution of the present invention may also involve providing two coupling gratings 22 at the coupling portion, and the grating parameters of the two coupling gratings 22 are different, so as to satisfy a special correspondence with the first coupling grating 23a and the second coupling grating 23b of the coupling portion, respectively.

[0063] With this configuration, when the operating mode of the display device 100 is confirmed to be internal display mode, the light beam from the light-emitting component 10 is only incident in the first coupling area of ​​the optical component 20, and the display device 100 can emit the internal display beam inward only through the first coupling area. When the operating mode of the display device 100 is confirmed to be external display mode, the light beam from the light-emitting component 10 is only incident in the second coupling area of ​​the optical component 20, and the display device 100 can project the external display beam outward only through the second coupling area.

[0064] Of course, the technical solution of the present invention is not limited to this. In other embodiments, the technical solution of the present invention may also be to provide a coupling grating 22 at the coupling part, and the grating parameters of the coupling grating 22 can be adjusted so that by changing the grating parameters of the coupling grating 22, it can satisfy a special correspondence with the first coupling grating 23a and the second coupling grating 23b of the coupling part respectively.

[0065] Furthermore, when the light-emitting component 10 emits a light beam toward the first coupling region and the second coupling region, it can output the same image information to the first coupling region and the second coupling region, so that the inner display beam and the outer display beam are used to display the same information content; of course, when the light-emitting component 10 emits a light beam toward the first coupling region and the second coupling region, it can also output different image information to the first coupling region and the second coupling region, so that the inner display beam and the outer display beam are used to display different information content.

[0066] It should be noted that in the aforementioned embodiments, the two coupling gratings of the optical component 20 can both be disposed on the same side of the coupling section. When the light beam emitted from the light-emitting component 10 is transmitted to the coupling grating 22 of the coupling section, it can be transmitted to the two coupling gratings on the substrate 21 respectively, so as to be emitted as inner and outer display beams through the two coupling gratings. In this arrangement, the propagation paths of the inner and outer display beams in the optical component 20 partially overlap. By controlling the light-emitting component 10 to emit beams separately to the first coupling area or the second coupling area, it is possible to avoid the inner and outer display beams from being transmitted in the optical component 20 at the same time, which would cause them to interfere with each other during transmission and affect the display effect of the display device 100.

[0067] Of course, the technical solution of the present invention is not limited thereto. In one feasible embodiment, after the light beam emitted by the light-emitting component 10 is transmitted to the coupling grating 22 of the coupling section, the propagation paths of the inner and outer display beams within the optical component 20 can be set separately. For example, the first coupling-out region and the second coupling-out region can be respectively set on both sides of the coupling section. In this arrangement, the light-emitting component 10 can be controlled to emit a light beam separately into the first coupling-out region or the second coupling-out region of the coupling section, so that the display device 100 emits an inner display beam or an outer display beam separately. Alternatively, the light beam emitted by the light-emitting component 10 can be controlled to simultaneously incident on the first coupling-out region and the second coupling-out region of the coupling section, so that the display device 100 can simultaneously emit an inner display beam inward and project an outer display beam outward. Specific implementation methods can be set according to actual needs and are not limited here.

[0068] Please see Figure 6 In an embodiment of the present invention, the light-emitting component 10 includes a first light-emitting region 11 and a second light-emitting region 12. The step of controlling the light beam emitted by the light-emitting component 10 to be incident on the first coupling region and / or the second coupling region according to the operating mode, so that the light beam is emitted from the first coupling region and / or the second coupling region, includes:

[0069] Step S31: When the working mode is internal display mode, control the first light emitting area 11 to emit a light beam toward the first coupling area so that the first coupling area corresponds to the emitted light beam.

[0070] Step S32: When the working mode is external display mode, control the second light emitting area 12 to emit a light beam toward the second coupling area so that the second coupling area corresponds to the emitted light beam.

[0071] In this embodiment, the first coupling region and the second coupling region can be disposed on one side surface of the substrate 21. By disposing the first coupling region and the second coupling region on the same side surface of the substrate 21, when there is only one light-emitting component 10, the light-emitting component 10 can be disposed on one side of the substrate 21 and can alternately emit light beams to the first coupling region and the second coupling region, thereby forming inner and outer display beams respectively through the light beam emitted by a single light-emitting component 10.

[0072] Specifically, the light-emitting assembly 10 may have a first light-emitting region 11 and a second light-emitting region 12 arranged side by side, which can be used to alternately emit light beams. The first light-emitting region 11 and a first coupling region are arranged opposite each other, and the light emitted from the first light-emitting region 11 can be emitted towards the first coupling region along a first light-emitting path. The second light-emitting region 12 and the second coupling region are arranged opposite each other, and the light emitted from the second light-emitting region 12 can be emitted towards the second coupling region along a second light-emitting path.

[0073] Of course, the technical solution of the present invention is not limited to this. In some embodiments, the relative positional relationship between the light-emitting component 10 and the coupling grating 22 can be adjusted so that the light beam emitted by the light-emitting component 10 can be transmitted to the first coupling region and the second coupling region respectively. For example, the light-emitting component 10 can be movably arranged and has a first light-emitting position and a second light-emitting position. When the light-emitting component 10 is in the first light-emitting position, it is arranged opposite to the first coupling region to emit a light beam towards the first coupling region along the first light-emitting path; when the light-emitting component 10 is in the second light-emitting position, it is arranged opposite to the second coupling region to emit a light beam towards the first coupling region along the second light-emitting path. Alternatively, the position of the light-emitting component 10 can be kept unchanged, and a light guide structure can be provided between the light-emitting component 10 and the optical component 20. The light guide structure can adjust the propagation path of the light beam emitted by the light-emitting component 10 so that the light beam emitted by the light-emitting component 10 can be transmitted to the first coupling region or the second coupling region along the first light-emitting path or the second light-emitting path respectively. Specific implementation methods can be set according to actual needs and are not limited here.

[0074] Please see Figure 7 In an embodiment of the present invention, two light-emitting components 10 are provided. The step of controlling the light beam emitted by the light-emitting component 10 to be incident on the first coupling region and / or the second coupling region according to the working mode, so that the light beam is emitted from the first coupling region and / or the second coupling region, includes:

[0075] Step S33: When the working mode is the internal display mode, control one of the light-emitting components 10 to emit a light beam toward the first coupling area, so that the first coupling area corresponds to the emitted light beam.

[0076] Step S34: When the working mode is external display mode, control another light-emitting component 10 to emit a light beam toward the second coupling area so that the second coupling area corresponds to the emitted light beam.

[0077] In this embodiment, the two light-emitting components 10 are designated as a first light-emitting component 10a and a second light-emitting component 10b. When the display device 100 is operating normally, the first light-emitting component 10a and the second light-emitting component 10b can emit light of internal and external display types towards the first coupling area and the second coupling area, respectively, causing the light beam from the coupled substrate 21 to be emitted outward through the first and second coupling areas, respectively, so that the display device 100 outputs corresponding internal and external display information. When the display type needs to be adjusted, the operating state of the corresponding light-emitting component 10 can be adjusted. For example, when the display device 100 needs to emit only internal display light beams inward, the first light-emitting component 10a is controlled to emit light beams only towards the first coupling area, and the second light-emitting component 10b stops emitting light outward; or, when the display device 100 needs to emit only external display light beams outward, the second light-emitting component 10b is controlled to emit light beams only towards the second coupling area, and the first light-emitting component 10a stops emitting light outward. Other display type adjustments are similar and will not be elaborated here.

[0078] It should be noted that when two light-emitting components 10 are provided, the two light-emitting components 10 can be integrated and disposed on one side of the substrate 21, which is beneficial to improving the structural compactness of the display device 100, thereby reducing the volume occupied by the display device 100. Of course, the technical solution of the present invention is not limited to this. In some embodiments, when two light-emitting components 10 are provided, the first coupling region and the second coupling region can also be disposed on the two side surfaces of the substrate 21, and the two light-emitting components 10 can be disposed on opposite sides of the substrate 21, so that the two light-emitting components 10 are respectively disposed corresponding to the first coupling region and the second coupling region. The number and placement of the light-emitting components 10 can be set according to actual needs and are not limited here.

[0079] In one embodiment of the present invention, prior to the step of receiving the control command, the following steps are included:

[0080] Receive power-on command;

[0081] Control the operation of the light-emitting component 10 in the display mode.

[0082] In this way, the initial working mode of the display device 100 after power-on can be configured as the internal display mode, so that the display device 100 can directly emit a beam of light inward after power-on, thereby realizing the basic internal display function of the display device 100.

[0083] Furthermore, in one embodiment of the present invention, the step of confirming the operating mode of the display device 100 according to the control command includes:

[0084] When the control command is a switching command, the current working mode of the display device 100 is switched;

[0085] When the control command is a maintain command, the current operating mode of the display device 100 is maintained.

[0086] In this embodiment, the control command includes a mode switching command. The mode switching command includes at least a switching command. When the control command is a switching command, the display device 100 can switch its current operating mode. For example, after receiving the switching command, the optical component 20 of the display device 100, which is in internal display mode, can switch from emitting light from the first coupling area to emitting light from the second coupling area, thereby switching the display device 100 to external display mode and enabling the display device 100 to project externally. The same principle applies to other operating mode adjustments, and they will not be elaborated here. Furthermore, when the display device 100 is operating normally and the control command is a switching command, the step of switching the current operating mode of the display device 100 can be executed multiple times to control the display device 100 to alternate between internal and external display modes.

[0087] Furthermore, the mode switching instruction may also include a maintenance instruction. When the control instruction is a maintenance instruction, the current operating mode of the display device 100 is maintained. In some embodiments, the technical solution of the present invention can determine whether the control instruction is a maintenance instruction or a switching instruction based on user input information. In other embodiments, the technical solution of the present invention can also determine whether the type of the control instruction is a maintenance instruction or a switching instruction based on the current detection information of the device. For example, when it is detected that the display device 100 is in a wearing state and in an internal display mode, the control instruction is determined to be a maintenance instruction; when it is detected that the display device 100 is in a non-wearing state and in an internal display mode, the control instruction is determined to be a switching instruction. The determination of the type of other control instructions is similar and will not be elaborated here.

[0088] In one embodiment of the present invention, the step of receiving control commands includes:

[0089] When the display device 100 is in a wearing state, it receives a first control command;

[0090] When the display device 100 is in a non-wearing state, it receives a second control command.

[0091] In this embodiment, the control command includes a mode selection command, which includes at least a first control command and a second control command. Specifically, in the technical solution of the present invention, the display device 100 further includes a wear detection sensor, which may be one or more combinations of an accelerometer, a proximity sensor, a heart rate sensor, and a temperature sensor, to realize the wear status detection function of the display device 100.

[0092] Furthermore, based on the detection results of the wear detection sensor, it can be determined whether the display device is currently being worn. When the wear detection sensor detects that the display device 100 is currently being worn, the wear detection sensor can send a first detection signal to the controller of the display device 100. The controller of the display device 100 can generate a first control command based on the wear detection sensor, thereby controlling the display device 100 to emit an internal display beam through the first coupling area, so that the user can directly obtain relevant display information through the internal display beam of the display device 100.

[0093] When the wear detection sensor detects that the display device 100 is not currently being worn, the wear detection sensor can send a second detection signal to the controller of the display device 100. The controller of the display device 100 can then generate a second control command based on this wear detection sensor, thereby controlling the display device 100 to emit an external display beam through the second coupling area. This allows the user to directly obtain relevant display information through the external display beam projected by the display device 100. In this way, the light emission direction of the display device 100 can be controlled according to whether the wearable display device is being worn, which improves the ease of use and practicality of the wearable display device.

[0094] In embodiments of the present invention, the control commands include at least one of remote control commands, button control commands, and voice control commands.

[0095] Specifically, the control command can be a remote control command, for example, the display device can be remotely controlled via a mobile phone, computer, or other device through the cloud. Alternatively, the control command can also be a button control command, for example, the control command can be input to the display device 100 through a sliding or touching mechanism such as a touch button or mechanical switch. Or, the control command can also be a voice control command, which can be obtained by the voice pickup module of the display device 100 picking up the user's voice information. Of course, the control command can also be a combination of the above-mentioned control commands, which is not limited here.

[0096] Furthermore, this embodiment of the invention also provides a display device 100, which includes: a memory, a processor, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the control method of the display device 100 as described above.

[0097] Furthermore, embodiments of the present invention also provide a readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the control method for the display device 100 as described above.

[0098] Those skilled in the art will understand that all or part of the processes in the above embodiments can be implemented by a computer program instructing related hardware. The program can be stored in a computer-readable storage medium, and when executed, it can include the processes of the embodiments of the above methods. The storage medium can be a magnetic disk, optical disk, read-only memory (ROM), or random access memory (RAM), etc.

[0099] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
