Description

Technical Field

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

[0002] With the continuous advancement of display devices, augmented reality (AR) and virtual reality (VR) technologies are becoming widely used. For example, AR glasses and VR glasses have entered the market. Currently, both AR and VR glasses have limited usage scenarios, and their compatibility needs to be improved. Summary of the Invention

[0003] An embodiment of the present application provides a display device, aiming to improve the compatibility of the display device.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions.

[0005] An embodiment of the present application provides a display device. The display device includes a base, a display body, and a VR display module. The base has a first connecting portion; the display body is connected to the base; the VR display module has a VR light-emitting surface and a second connecting portion; when the display device is in a first state, the display body is connected to the VR display module, and the VR display module is connected to the base via the second connecting portion and the first connecting portion; and the vertical projection of the base on the VR light-emitting surface does not overlap with the light-emitting surface; the vertical projection of the display body on the light-emitting surface does not overlap with the VR light-emitting surface. Because the vertical projection of the base on the VR light-emitting surface does not overlap with the VR light-emitting surface, the base will not block the light emitted from the VR light-emitting surface, nor will the base block the light that passes through the VR light-emitting surface and enters the user's eyes. When the VR display module is replaced with other optical devices, if the relative position of the user's eyes and the base remains unchanged, the base will not block ambient light (such as sunlight) from passing through the aforementioned other optical devices and entering the human eye. For example, the aforementioned other optical device can be an AR display module. In other words, the vertical projection of the base on the VR light-emitting surface does not overlap with the light-emitting surface. When the VR display module is replaced with other optical devices that need to collect ambient light, the base will not block the ambient light. This allows the base to adapt to more optical devices, increasing the adaptability of the base. Similarly, when the VR display module is replaced with other optical devices that need to collect ambient light, the display body will not block the ambient light. This allows the display body to adapt to more optical devices, increasing the adaptability and compatibility of the display device.

[0006] In combination with the above, in some achievable embodiments of the present application, the display device further includes an AR display module, which has an AR light-emitting surface and a third connecting portion. When the display device is in the second state, the display body is connected to the AR display module, and the AR display module is connected to the base via the third connecting portion and the first connecting portion; and the vertical projection of the base on the AR light-emitting surface does not overlap with the light-emitting surface; the vertical projection of the display body on the light-emitting surface does not overlap with the AR light-emitting surface. Thus, the base does not block the propagation of ambient light. In other words, the base is not located on the propagation path of ambient light propagating to the user's eyes. Similarly, the vertical projection of the display body on the AR light-emitting surface does not overlap with the AR light-emitting surface. The display body does not block the propagation of ambient light. The base and the display body can be adapted to the AR display module and the VR display module. The base and the display body have good compatibility.

[0007] In combination with the above, in some achievable embodiments of the present application, the display device further includes a diaphragm. The diaphragm is connected to the base; when the display device is in the second state, the diaphragm is located on the side of the AR display module away from the AR light-emitting surface, and the diaphragm is used to transmit light. When the display device is in the second state, the diaphragm transmits light, and the light-transmitting diaphragm does not block the user from viewing the object. The ambient light can be transmitted through the diaphragm to the AR display module and then received by the user. The diaphragm can also make the display device more beautiful and have a decorative effect.

[0008] In combination with the above, in some possible implementations of the present application, when the display device is in the first state, the diaphragm is used to reflect or absorb light. When the display device is in the second state, the user needs to observe objects in the environment, the diaphragm is used to transmit light, and ambient light can enter the user's eyes through the diaphragm. When the display device is in the first state, the user does not need to receive ambient light, and the diaphragm is used to reflect or absorb light, which can prevent light from entering the VR display module.

[0009] In combination with the above, in some possible implementations of the present application, the display body includes a printed circuit board; the printed circuit board is connected to the base. When the display device is in the first state, the printed circuit board is electrically connected to the VR display module; and the vertical projection of the printed circuit board on the VR light-emitting surface does not overlap with the light-emitting surface. When the display device is in the second state, the printed circuit board is electrically connected to the AR display module; and the vertical projection of the printed circuit board on the AR light-emitting surface does not overlap with the light-emitting surface.

[0010] In combination with the above, in some implementable manners of the embodiments of the present application, when the display device is in the first state, the second connecting portion is engaged with the first connecting portion.

[0011] In conjunction with the above, in some possible implementations of the present application, the second connection portion and the first connection portion are connected by a buckle and a slot. Alternatively, the slot is provided on the first connection portion and the buckle is provided on the second connection portion, and the buckle is provided on the first connection portion. The first and second connection portions are connected and separated by the connection of the buckle and the slot.

[0012] In conjunction with the above, in some possible implementations of the embodiments of the present application, the display device further includes an elastic member elastically connected to the buckle; when the display device is in the first state, the elastic member is in a compressed state. Thus, the compressed elastic member applies an elastic force to the buckle, which prevents the buckle from disengaging from the slot.

[0013] In combination with the above, in some achievable embodiments of the present application, the card slot is long and narrow, and the buckle is slidably connected to the card slot along the length of the card slot. In this way, the relative position of the buckle and the card slot can be moved. The relative position of the first connecting portion and the second connecting portion can also be changed. The user can set the relative position of the first connecting portion and the second connecting portion as needed, thereby changing the relative position of the VR display module and the base.

[0014] In conjunction with the above, in some possible implementations of the present application, the base has multiple first connecting portions, which are spaced apart. When the display device is in the first state, the second connecting portion connects to one of the multiple first connecting portions. By selecting the second connecting portion to connect to the first connecting portion, the distance between the two VR display modules can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In addition, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0029] An embodiment of the present application provides a display device. Figure 1 This is a schematic diagram of the exploded structure of the display device 10 provided in the embodiment of the present application. Figure 1 The display device 10 includes a base 20, a display body 30, and a VR display module 100. The display body 30 is connected to the base 20. The VR display module 100 is detachably connected to the base 20.

[0030] Figure 2 This is a structural schematic diagram of the display device 10 provided in an embodiment of the present application in a first state. Figure 2 In the embodiment, the VR display module 100 is connected to the base 20, and the display device 10 is in the VR display mode.

[0031] The base 20 has a first connection portion 410. The VR display module 100 has a second connection portion 420. The first connection portion 410 and the second connection portion 420 are detachably connected. When the display device 10 is in the first state, the VR display module 100 is connected to the base 20 via the first connection portion 410 and the second connection portion 420. In other words, when the display device 10 is in the first state, the first connection portion 410 and the second connection portion 420 are connected.

[0032] Figure 3 This is a structural diagram of the VR display module 100 provided in an embodiment of the present application. Figure 3 The VR display module 100 may have a VR light emitting surface 101, and the VR light emitting surface 101 may be located on the VR display module 100. The VR light emitting surface 101 may be used to emit image light of the VR display module 100. When the display device 10 is in the first state, the display body 30 (eg Figure 2 The vertical projection of the base 20 on the VR light emitting surface 101 does not overlap with the VR light emitting surface 101. The vertical projection of the base 20 on the VR light emitting surface 101 does not overlap with the VR light emitting surface 101.

[0033] Because the base 20 (such as Figure 2 As shown in the figure, the vertical projection of the base 20 on the VR light emitting surface 101 does not overlap with the VR light emitting surface 101, then the base 20 will not block the light emitted from the VR light emitting surface 101, and the base 20 will not block the light that passes through the VR light emitting surface 101 and enters the user's eyes. When the VR display module 100 is replaced with other optical devices, under the condition that the relative position of the user's eyes and the base 20 remains unchanged, the base 20 will not block the ambient light (such as sunlight) from passing through the aforementioned other optical devices and entering the human eye. For example, the aforementioned other optical devices may be AR display modules. In other words, the vertical projection of the base 20 on the VR light emitting surface 101 does not overlap with the VR light emitting surface 101. When the VR display module 100 is replaced with other optical devices that need to collect ambient light, the base 20 will not block the ambient light. This allows the base 20 to adapt to more optical devices, thereby increasing the adaptability of the base 20.

[0034] For example, the vertical projection of the base 20 on the VR light exit surface 101 refers to the projection of the base 20 on the plane of the VR light exit surface 101 in a direction perpendicular to the plane of the VR light exit surface 101. The same applies to other descriptions of vertical projection in this document.

[0035] The aforementioned vertical projection of the base 20 on the VR light emitting surface 101 not overlapping with the VR light emitting surface 101 means that the vertical projection of the base 20 on the VR light emitting surface 101 is outside the VR light emitting surface 101 .

[0036] Similarly, the vertical projection of the display body 30 on the VR light-emitting surface 101 does not overlap with the VR light-emitting surface 101; the display body 30 will not block the light emitted from the VR light-emitting surface 101, nor will the display body 30 block the light that passes through the VR light-emitting surface 101 and enters the user's eyes. When the VR display module 100 is replaced with other optical devices, under the condition that the relative position of the user's eyes and the display body 30 remains unchanged, the display body 30 will not block ambient light (such as sunlight) from passing through the aforementioned other optical devices and entering the human eye. For example, the aforementioned other optical devices may be the AR display module 200. In other words, when the VR display module 100 is replaced with other optical devices that need to collect ambient light, the display body 30 will not block the ambient light. This allows the display body 30 to adapt to more optical devices, increases the adaptability of the display device 10, and improves the compatibility of the display device 10.

[0037] The aforementioned vertical projection of the display body 30 on the VR light emitting surface 101 not overlapping with the VR light emitting surface 101 means that the vertical projection of the display body 30 on the VR light emitting surface 101 is outside the VR light emitting surface 101 .

[0038] like Figure 3 As shown, in some embodiments, the VR display module 100 includes a first display panel 110 and a first lens assembly 120. The VR light-emitting surface 101 is located on the first lens assembly 120. The first display panel 110 is used to display the image displayed by the display body 30 (such as Figure 2 ) produced by the image.

[0039] Exemplarily, the first display panel 110 may be a microdisplay suitable for a virtual reality device. Exemplarily, the first display panel 110 may include an emissive microdisplay, which can provide a higher image resolution in a smaller size (e.g., less than 1 inch). The emissive microdisplay is, for example, an organic light-emitting diode (OLED) array display type, an inorganic light-emitting diode (iLED) array display type, and / or any other suitable microdisplay. The first display panel 110 may include one or more light sources, such as an RGBLED array, one or more white LEDs (e.g., with a color filter device), and / or any suitable lighting source structure.

[0040] The first lens assembly 120 receives the divergent image light from the first display panel 110, collimates and forms an image of the image light, and then transmits it to the user's eyes through the VR light-emitting surface 101. Collimation refers to converting the spherical light emitted by each pixel on the first display panel 110 into parallel light emitted in all directions.

[0041] Please return Figure 2 The display device 10 includes two VR display modules 100, and the two VR display modules 100 are arranged at intervals along the x-direction. The image light emitted by one VR display module 100 enters the user's left eye, and the image light emitted by the other VR display module 100 enters the user's right eye. Both VR display modules 100 are connected to the base 20. Both VR display modules 100 are detachably connected to the display body 30. Each VR display module 100 is configured with a first connecting portion 410. The base 20 is provided with two second connecting portions 420. The two first connecting portions 410 and the two second connecting portions 420 are connected in a one-to-one correspondence.

[0042] In some embodiments, two VR display modules 100 can be connected to each other, and the two VR display modules 100 are connected to the base 20 via a first connection portion 410 and a second connection portion 420. In other words, the two VR display modules 100 share one first connection portion 410.

[0043] Similarly, the two VR display modules 100 can be connected to the display main body 30 via signal lines respectively. Alternatively, the two VR display modules 100 can be connected to the display main body 30 via one signal line.

[0044] For example, the display body 30 may include a printed circuit board 31. When the display device 10 is in the first state, the printed circuit board 31 is electrically connected to the VR display module 100. The printed circuit board 31 is used to provide image information and output this image information to the VR display module 100. In some embodiments of the present application, the display body 30 may also include components such as a battery and a sensor. The base 20 may be provided with a storage space, and the display body 30 is accommodated within this storage space.

[0045] The present application embodiment does not limit the structure of the base 20. In some embodiments, the base 20 includes a wearable structure. For example, in an embodiment where the display device 10 is a head-mounted device, the base 20 may include a head-mounted structure. Figure 2 The base 20 includes an open-loop structure 21, which is used to be worn on the user's head.

[0046] The present embodiment of the present application does not limit the material of the open-loop structure 21. For example, the open-loop structure 21 is made of an elastic material. The elasticity of the elastic material allows the inner diameter of the open-loop structure 21 to be adjusted for easier wearing. It will be appreciated that in some embodiments, the base 20 can be configured in the shape of an eyeglass frame.

[0047] In some embodiments, to make the open-loop structure 21 more aesthetically pleasing, a coating or plating layer may be provided on the surface of the open-loop structure 21. The coating or plating layer may present different patterns or colors, so that the open-loop structure 21 also serves a decorative purpose.

[0048] The embodiment of the present application does not limit the connection method between the open-loop structure 21 and the display body 30. For example, the open-loop structure 21 and the display body 30 can be connected by snapping, welding, bonding or screwing.

[0049] In an embodiment where the base 20 includes a head-mounted open-loop structure 21 , when the display device 10 is in a wearable state, the base 20 is located above the VR display module 100 , where the aforementioned above includes directly above and obliquely above.

[0050] When the display device 10 is in the first state, it is in VR display mode, and the user can receive image light emitted by the VR display. The principle of VR display mode is to introduce real scene information into the virtual environment, establishing an interactive feedback information loop between the virtual world, the real world, and the user, to enhance the realism of the user experience. Therefore, in VR display mode, the user does not need to receive ambient light.

[0051] Please return Figure 1In some embodiments of the present application, the display device 10 may further include an AR display module 200. The AR display module 200 is detachably connected to the base 20. For example, the AR display module 200 has a third connection portion 430, which is detachably connected to the first connection portion 410. The AR display module 200 is detachably connected to the display body 30.

[0052] The display device 10 can have both an AR display module and a VR display module. When the AR display module is required, the display device is adjusted to AR display mode. When the VR display module is required, the display device is adjusted to VR display mode. For example, when the display device is in the first state, the display device is in VR display mode. When the display device is in the second state, the display device is in AR display mode.

[0053] When the display device 10 is in the first state, the third connection portion 430 and the first connection portion 410 are in a disassembled state, and the second connection portion 420 (eg Figure 3 The AR display module 200 and the display body 30 are in a disassembled state, and the VR display module 100 and the display body 30 are in a connected state.

[0054] Figure 4 This is a structural schematic diagram of the display device 10 provided in an embodiment of the present application in the second state. Figure 4 In the embodiment of the present invention, the display device 10 is in the AR display mode. The VR display module 100 is not connected to the base 20, and the AR display module 200 is connected to the base 20.

[0055] Figure 4 In the embodiment, when the display device 10 is in the second state, the base 20 and the AR display module 200 are connected via the third connection portion 430 and the first connection portion 410. The display body 30 and the AR display module 200 are connected.

[0056] The AR display module 200 further includes an AR light emitting surface 201. The AR light emitting surface 201 is located on the AR display module 200 and is used to emit image light of the AR display module 200.

[0057] When the display device 10 is in the second state, the vertical projection of the base 20 on the AR light emitting surface 201 does not overlap with the AR light emitting surface 201 . The vertical projection of the display body 30 on the AR light emitting surface 201 does not overlap with the AR light emitting surface 201 .

[0058] Figure 5 Schematic diagram of the light path when the display device 10 is in the second state. Figure 5 When the display device 10 is in AR display mode, the user can receive the light in the real environment and the image light emitted by the AR display module 200. Figure 5 For example, the user can receive the image light emitted by the AR display module 200 to obtain the information carried by the image light. The user can also receive ambient light to observe the object 101 in the environment.

[0059] And because the vertical projection of the base 20 on the AR light emitting surface 201 does not overlap with the AR light emitting surface 201. The base 20 will not block the propagation of ambient light. In other words, the base 20 is not located on the propagation path of the ambient light propagating to the user's eyes. Similarly, the vertical projection of the display body 30 on the AR light emitting surface 201 does not overlap with the AR light emitting surface 201. The display body 30 will not block the propagation of ambient light. The aforementioned ambient light refers to light other than the image light emitted by the AR display screen. For example, the ambient light can be sunlight, light or light emitted by other display devices such as televisions.

[0060] The base 20 and the display body 30 can be adapted to the AR display module 200 and the VR display module 100. The base 20 and the display body 30 have good compatibility.

[0061] For example, the base 20 includes a head-mounted open-loop structure 21. When the display device 10 is in a wearable state, the base 20 is located above the AR display module 200, where the above includes directly above and obliquely above.

[0062] Figure 6 This is a schematic diagram of the structure of the AR display module 200 provided in the embodiment of the present application. Figure 6 The AR display module 200 may include a second display panel 210 and a second lens assembly 220. The second display panel 210 is used to display the image displayed by the display body 30 (eg Figure 5 The second display panel 210 may be a microdisplay suitable for an AR device. Exemplarily, the second display panel 210 may include an organic light emitting diode array display type, an inorganic light emitting diode array display type, and / or any other suitable microdisplay. The second display panel 210 may include one or more light sources, such as an RGBLED array, one or more white LEDs (e.g., with a color filter device), and / or any suitable lighting source structure. The second lens assembly 220 receives the divergent image light from the second display panel 210, collimates and images the image light, and then transmits it to the user's eyes through the AR light emitting surface 201.

[0063] Figure 7 This is a simplified structural diagram of the display body 30, AR display module 200 and VR display module 100 provided in the embodiment of the present application. Figure 7 The display body 30 has a first electrical connection head 310 ; the VR display module 100 has a second electrical connection head 320 ; and the AR display module 200 has a third electrical connection head 330 .

[0064] The first electrical connector 310 and the second electrical connector 320 are detachably connected; the second electrical connector 320 and the third electrical connector 330 are detachably connected.

[0065] When the display device 10 is in the first state, the display body 30 is connected to the VR display module 100 through the first electrical connector 310 and the second electrical connector 320. The display body 30 can transmit signals to the VR display module 100 through the first electrical connector 310 and the second electrical connector 320.

[0066] When the display device 10 is in the second state, the display body 30 is connected to the AR display module 200 through the second electrical connector 320 and the third electrical connector 330. The display body 30 can transmit signals to the AR display module 200 through the second electrical connector 320 and the third electrical connector 330.

[0067] The present embodiment of the present application does not limit the structure of the first electrical connector 310. For example, the first electrical connector 310 may include a universal serial bus (USB) interface. The aforementioned USB interface may be a Mini USB interface, a Micro USB interface, a USB Type-C interface, etc. The second electrical connector 320 is a connector adapted to the USB interface. Alternatively, the second electrical connector 320 may be a USB interface, and the first electrical connector 310 is a connector adapted to the USB interface.

[0068] In some embodiments of the present application, when the first electrical connector 310 and the second electrical connector 320 are connected, both signal transmission and power transmission can be achieved between the first electrical connector 310 and the second electrical connector 320. For example, the display body 30 charges the VR display module 100 and transmits signals to the VR display module 100 through the first electrical connector 310 and the second electrical connector 320.

[0069] Similar to the second electrical connector 320, the third electrical connector 330 may also include a USB port or a connector compatible with a USB port. In some embodiments, when the first and third electrical connectors 310 and 330 are connected, the display body 30 charges the AR display module 200 and transmits signals to the AR display module 200 via the first and third electrical connectors 310 and 330.

[0070] As described above, the display body 30 may include a printed circuit board 31. When the display device 10 is in the second state, the printed circuit board 31 is connected to the AR display module 200. The printed circuit board 31 is used to provide image information and output this image information to the AR display module 200. In this way, the AR display module 200 and the VR display module 100 can use the same printed circuit board 31.

[0071] In some embodiments, the printed circuit board 31 may be provided with an AR application (APP) and a VR application. When the display device 10 is in a first state, the user can interact with the VR display module 100 through the VR application. When the display device 10 is in a second state, the user can interact with the AR display module 200 through the AR application.

[0072] Please return Figure 1 In some embodiments of the present application, the display device 10 may further include a diaphragm 50 connected to the base 20. When the AR display module 200 and the base 20 are connected, that is, when the display device 10 is in the second state, the diaphragm 50 is located on the side of the AR display module 200 facing away from the AR light emitting surface 201, and the diaphragm 50 is used to transmit light.

[0073] like Figure 5 As shown, the film 50 transmits light, so ambient light can be transmitted through the film 50 to the AR display module 200 and then received by the user. When the display device 10 is in the second state, the light-transmitting film 50 does not block the user from viewing the object 101. The film 50 can make the display device 10 more beautiful.

[0074] In some embodiments, the film 50 covers the base 20 and the display body 30 . The film 50 can shield the base 20 and the display body 30 , making the appearance of the display device 10 more uniform.

[0075] The embodiment of the present application does not limit the shape of the membrane 50 and can be configured as required. For example, the shape of the membrane 50 can be adapted to the appearance of the display device 10.

[0076] The embodiment of the present application does not limit the connection method between the diaphragm 50 and the base 20. For example, the diaphragm 50 and the base 20 can be connected by bonding or screwing.

[0077] In some embodiments, the diaphragm 50 is made of a light-transmitting material, such as glass, light-transmitting resin, etc. In some embodiments of the present application, the diaphragm 50 can have multiple states. In some states, the diaphragm 50 is in a light-transmitting state for transmitting light. In other embodiments, the diaphragm 50 is in a non-light-transmitting state for reflecting or absorbing light.

[0078] For example, when the display device 10 is in the second state, the film 50 is used to transmit light. When the display device 10 is in the first state, the film 50 is used to reflect or absorb light. When the display device 10 is in the second state, the user needs to observe the object 101 (such as Figure 5 As shown, the diaphragm 50 is used to transmit light, and ambient light can enter the user's eyes through the diaphragm 50. When the display device 10 is in the first state, the user does not need to receive ambient light, and the diaphragm 50 is used to reflect or absorb light to prevent light from entering the VR display module 100.

[0079] In some embodiments, the diaphragm 50 includes an electrochromic material. Electrochromic materials are capable of changing color by applying an electric field. The transmittance of electrochromic materials is variable between 0% and 90%, and can change from opaque to transparent. The principle is that when a voltage is applied, the ions in the electrochromic material will move under the action of the electric field, causing the optical properties of the material to change. In embodiments where the diaphragm 50 includes an electrochromic material, the diaphragm 50 can be configured with a controller for controlling the voltage applied to the diaphragm 50. Exemplarily, the electrochromic material may include tungsten trioxide polythiophene and its derivatives, viologens, tetrathiafulvalene, metal phthalocyanine compounds, and the like.

[0080] In some embodiments, membrane 50 includes a liquid crystal material, which can adjust its transmittance using an applied electric or magnetic field. The orientation and arrangement of the liquid crystal molecules affect their transmittance in the electric or magnetic field, thereby achieving color change. Liquid crystal materials have the advantages of fast response speed and uniformity over large sizes.

[0081] Since the user does not need to receive ambient light when the display device 10 is in the first state, the film 50 can also transmit light when the display device 10 is in the second state. In other words, the film 50 does not need to have a light-reflecting property.

[0082] As mentioned above, the first connection part 410 and the second connection part 420 are detachably connected. It is understandable that there are many ways to achieve the detachable connection between the first connection part 410 and the second connection part 420. Figure 8 A detachable connection method between the first connection portion 410 and the second connection portion 420 is described as an example.

[0083] Figure 8 This is a schematic diagram of the structure of the first connecting portion 410 and the second connecting portion 420 provided in the embodiment of the present application. Figure 8 The first connecting portion 410 and the second connecting portion 420 are snap-fitted. The snap-fitting method facilitates the separation and connection of the first connecting portion 410 and the second connecting portion 420.

[0084] Figure 8 In the embodiment, the first connection part 410 and the second connection part 420 are connected by a buckle 421 and a slot 411. For example, the first connection part 410 is provided with a slot 411, and the second connection part 420 is provided with a buckle 421, and the buckle 421 and the slot 411 are engaged. The connection between the buckle 421 and the slot 411 enables the first connection part 410 and the second connection part 420 to be separated and connected.

[0085] Please return Figure 3 In some embodiments, the second connection portion 420 includes four buckles 421, and the four buckles 421 are spaced apart and arranged on the second connection portion 420. For example, the first connection portion 410 is a square plate, and the four buckles 421 are respectively arranged at the four corners of the square plate. Figure 8 As shown) is provided with four card slots 411 (as shown Figure 8 As shown, the four slots 411 and the four buckles 421 are connected in a one-to-one manner. This provides multiple points of support between the first and second connecting portions 410, 420 when they are connected, thereby increasing the stability of the connection between the first and second connecting portions 410, 420. It will be appreciated that in some embodiments, the number of buckles 421 may be one, two, three, five, or more. Similarly, the number of slots 411 is the same as the number of buckles 421.

[0086] Please return Figure 8 In some embodiments, the buckle 421 has a first end 4211 and a second end 4212. The first end 4211 is located inside the first connection portion 410 and is connected to the first connection portion 410. The second end 4212 is located outside the first connection portion 410 and is a free end. When the first connection portion 410 and the second connection portion 420 are in a connected state, the second end 4212 extends into the slot 411 and engages with the slot 411. When the first connection portion 410 and the second connection portion 420 need to be separated, the portion of the buckle 421 located between the first end 4211 and the second end 4212 is pressed to separate the second end 4212 from the slot 411.

[0087] Figure 9 This is a schematic diagram of the structure of the second connecting portion 420 provided in the embodiment of the present application. Figure 9 In some embodiments, the display device 10 further includes an elastic member 440. The elastic member 440 is elastically connected to the buckle 421. When the display device 10 is in the first state, the elastic member 440 is in a compressed state. The compressed elastic member 440 exerts an elastic force on the buckle 421, which prevents the buckle 421 from separating from the slot 411.

[0088] For example, the elastic member 440 is located within the second connecting portion 420 and is elastically connected to the first end 4211. In some embodiments, the elastic member 440 may be a spring. In embodiments where there are multiple buckles 421, one end of the elastic member 440 is elastically connected to one buckle 421, and the other end of the elastic member 440 is elastically connected to another buckle 421.

[0089] Figure 10 This is a schematic diagram of the structure of the buckle 421 and the slot 411 provided in the embodiment of the present application. Figure 10 In some embodiments of the present application, the card slot 411 is long and narrow, and the buckle 421 is slidably connected to the card slot 411 along the length direction of the card slot 411. In this way, the relative position of the buckle 421 and the card slot 411 can be moved. The relative position of the first connecting portion 410 and the second connecting portion 420 can also be changed. The user can set the relative position of the first connecting portion 410 and the second connecting portion 420 as needed, thereby changing the relative position of the VR display module and the base.

[0090] In some embodiments, the two VR display modules 100 extend along the x-direction, and the length direction of the card slot 411 is the x-direction. The buckle 421 is slidably connected to the card slot 411 along the x-direction. The distance between the buckle 421 and the card slot 411 along the x-direction can be adjusted. Therefore, the distance between the first connecting portion 410 and the second connecting portion 420 along the x-direction can be adjusted. Because the two VR display modules 100 extend along the x-direction, the distance between the two VR display modules 100 can be adjusted. The user can adjust the distance between the two VR display modules 100 according to the distance between the left eye and the right eye.

[0091] There are many ways to implement the sliding connection between the buckle 421 and the slot 411. For example, a slide rail is provided inside the slot 411, and the buckle 421 is slidably connected to the slide rail.

[0092] In some embodiments, the distance between the two VR display modules 100 can be adjusted by other means, for example, by providing a plurality of second connection portions 420 on the base 20, and connecting the first connection portion 410 to one of the plurality of second connection portions 420. The distance between the two VR display modules 100 can be adjusted by selecting the second connection portion 420 that is connected to the first connection portion 410.

[0093] exist Figure 8In the example shown, the buckle 421 is provided on the second connecting portion 420, and the slot 411 is provided on the first connecting portion 410. It will be appreciated that in some embodiments, the slot 411 is provided on the second connecting portion 420, and the buckle 421 is provided on the first connecting portion 410. Similarly, the second connecting portion 420 and the first connecting portion 410 can be connected by connecting the slot 411 and the buckle 421. In the embodiment where the buckle 421 is provided on the first connecting portion 410, the elastic member 440 is provided on the first connecting portion 410 and elastically connected to the buckle 421.

[0094] It is understandable that, in some embodiments of the present application, the second connection portion 420 and the first connection portion 410 are not limited to being connected by snap-fitting, and may be connected in other ways.

[0095] As described above, when the display device 10 is in the second state, the base 20 and the AR display module 200 are connected via the third connection portion 430 and the first connection portion 410. In the embodiment of the present application, the structure of the third connection portion 430 is the same as that of the second connection portion 420 and will not be further described here. The first connection portion 410 can be adapted to the second connection portion 420 and the third connection portion 430. This allows the base 20 to adapt to the VR display module 100 and the AR display module 200.

[0096] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
