[0029] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0030] The present application provides a near-eye display device. Please refer to Figures 1 - 2 , the near-eye display device 100 may include a wearing component 10 and a display component 20. The wearing component 10 can be worn by a user, such as worn on the head. Exemplarily, the wearing component 10 can be glasses or a helmet, etc. The wearing component 10 is provided with a frame 12, and a lens 11 is mounted on the frame 12. When the wearing component 10 is glasses, the frame 12 can be a spectacle frame; when the wearing component 10 is a helmet, the frame 12 can be a helmet shell. The lens 11 can be a lens for myopia, hyperopia, eye protection, sunglasses, or fashion glasses, or a lens for a helmet or other head-mounted devices. The lens 11 has a viewing area 111, such as Figure 3As shown, the user's eyes can observe the external environment side through the visual field area 111 from the eye side. The size of the lens 11 can be set as needed. Among them, in the normal use state of the wearing component 10 (such as a relatively comfortable wearing state with suitable interpupillary distance), the area where the light transmitted through the lens 11 can be observed by the user's eyes is the visual field area 111; the area where the light cannot pass through the lens 11, and the area where the lens 11 can transmit light but the user's eyes cannot observe is outside the visual field area 111. Due to the differences in vision among different users, for different users, the visual field area 111 of the lens 11 will be slightly different.

[0031] Please continue to refer to Figures 1 - 2 , a state control bit 121 is provided on the frame 12 and / or the lens 11, and the state control bit 121 is located at the edge of the lens 11. Optionally, the state control bit 121 is provided on the frame 12. For example, when the wearing component 10 is glasses, the state control bit 121 is provided on the frame 12 (the spectacle frame); or, the state control bit 121 is provided on the lens 11. For example, when the wearing component 10 is a helmet, at this time the size of the lens 11 is relatively large, and the state control bit 121 can be provided in the edge area of the lens 11; or, the state control bit 121 is provided on the frame 12 and the lens 11, that is, the state control bit 121 is located at the connection between the frame 12 and the lens 11, with a part located on the frame 12 and the other part located on the lens 11. The setting method of the state control bit 121 can be a notch, as Figure 4 shown; the setting method of the state control bit 121 can also be a hole, as Figure 5 shown. Optionally, the state control bit 121 penetrates through two opposite surfaces of the frame 12 and / or the lens 11, that is, the state control bit 121 can be a through hole; the state control bit 121 can also be a groove formed by partial depression of one surface of the frame 12 and / or the lens 11. It can be understood that when the number of state control bits 121 involves multiple, it can also be one or a combination of blind holes, through holes, notches, etc.

[0032] The display component 20 is provided with a display module 21 for displaying preset image content. The display module 21 can adopt, for example, Micro-LED (Micro Light-Emitting Diode), Micro-oled (Micro Organic Light-Emitting Diode), LCoS (Liquid Crystal On Silicon), LCD (Liquid Crystal Display), DMD (Digital Micromirror Device) / DLP (Digital Light Processing), or LBS (Laser Beam Scanning), etc., or any combination of these technologies. Among them, the preset image content can be image information when implementing the AR display function, and the image content is different from the external environment observed by the user through the viewing area 111 of the lens 11. Optionally, the orthographic projection area of the display module 21 on the lens 11 is much smaller than the area of the lens 11. For example, the maximum orthographic projection area of the display module 21 on the lens 11 is not greater than 6mm 2 , in some embodiments, the maximum outer diameter of the display module 21 can not exceed 10mm, for example, it can be 10mm, 8.5mm, 5mm, etc. The above embodiments can reduce the volume of the display module 21, facilitate the adaptation with the wearing component 10, and reduce the influence of the display module 21 on the field of view. The display module 21 is configured to move on the lens 11. When the display module 21 is located at the state control position 121, the display module 21 is configured to switch to the target state. Optionally, when the display module 21 is located at the state control position 121, the display module 21 is electrically connected to the state control position 121, so as to realize the switching of the target state of the display module 21; of course, the connection between the display module 21 and the state control position 121 can also be wireless (such as 2.4g, radio frequency, Bluetooth, WiFi, etc.).

[0033] Optionally, the state control bit 121 includes a shape adapted to and / or complementary to at least a part of the wall of the display module 21. At least a part of the wall of the display module 21 may be a bottom wall or a side wall. It can be understood that if the outer wall (such as the bottom wall or the side wall) of the display module 21 protrudes, the inner wall of the state control bit 121 is recessed accordingly. For example, if the display module 21 is cylindrical, the shape of the state control bit 121 is an arc-shaped groove; or, if the display module 21 is rectangular, the state control bit 121 is rectangular or has a shape with inner chamfers, so that the two shapes can be adapted, and the display module 21 is located in the state control bit 121. With such a setting, when the display module 21 is located in the state control bit 121, on the one hand, the state control bit 121 forms a protection for the display module 21, which can prevent external foreign objects from touching the display module 21 and causing damage; on the other hand, the display module 21 can be hidden in the state control bit 121, and it is not easy to observe the display module 21 from the external environment side, which can reduce the impact of the display module 21 on the appearance of the near-eye display device 100.

[0034] In the near-eye display device 100 provided by the present application, a state control bit 121 is provided on the frame 12 and / or the lens 11, and the display module 21 is configured to move on the lens 11. When the display module 21 is located in the state control bit 121, the display module 21 is configured to switch to a target state, and the target state can be switched by moving the display module 21, and the switching operation is convenient and fast.

[0035] The target state of the display module 21 may be the state that the display module 21 has when in use or turned off. Exemplarily, the target state of the display module 21 includes any one of charging, power-on, data transmission, high-performance display, standby, power-off or low-performance display, or a state formed by a combination of some of the above states. For example, when the user needs to switch the target state of the display module 21 to charging, standby or high-performance display while charging, the user only needs to move the display module 21 to the state control bit 121 to achieve the state switching.

[0036] Optionally, the target state when the display module 21 is located in the state control bit 121 is predefined. That is, the target states that the state control bit 121 can achieve are preset when the product leaves the factory. When the user moves the display module 21 to the state control bit 121, the preset target states, such as charging, standby, etc., can be achieved. Since no user intervention is required for setting, the operation is simple, which can improve the usability of the near-eye display device 100.

[0037] Optionally, the target state when the display module 21 is located at the state control bit 121 is configured to be user-defined. Exemplarily, encoding signals set corresponding to different state control bits 121 are pre-stored. For example, the encoding signals generated when the state control bit 121 is electrically conducted are numbered 001, 002, 003, 004, etc. respectively. The 001 encoding signal is pre-stored or defined as the charging state, the 002 encoding signal is the low-performance display, the 003 encoding signal is the power-on state, the 004 encoding signal is the telephone function startup state, etc. The user can customize the target state when the display module 21 is located at the state control bit 121 as 001, 002, 001 and 003, or 001 and 004, etc. according to needs. Such a setting enables the user to customize the target state achievable by the state control bit 121 according to usage habits, thereby meeting the usage requirements of different users.

[0038] The number of settings of the state control bit 121 can be 1, as shown in Figure 1 、 Figure 2 ; The number of settings of the state control bit 121 can also be multiple, as shown in Figures 3 - 5 . Exemplarily, the number of settings of the state control bit 121 can be 2, 3, 4, etc., and no specific limitation is made here. When the number of settings of the state control bit 121 is 1, as described above, the user can customize the target state achieved by the state control bit 121. For example, according to different requirements at different usage times, the user can change the target state achieved by the state control bit 121, and multiple target states can be achieved through 1 state control bit 121. Since the number of settings of the state control bit 121 is small, the influence on the appearance of the near-eye display device 100 caused by opening the state control bit 121 can be reduced. When the number of settings of the state control bit 121 is multiple, the target states achieved by each state control bit 121 can be different. When the user needs to switch the target state of the display module 21, only need to move the display module 21 to the corresponding state control bit 121, and the operation is convenient and fast.

[0039] Generally speaking, the power consumption when the image display function of the display module 21 is turned on is relatively high, while the power consumption when the image display function of the display module 21 is turned off is relatively low. The image display function of the display module 21 often needs to be switched between on and off, that is, the above operations are relatively frequent, and a more convenient operation method is required. Please refer to Figure 4 、 Figure 5, in one embodiment, the number of set state control bits 121 is two. The state control bits 121 include a first state control bit 121a and a second state control bit 121b. When the display module 21 is at the first state control bit 121a, the target state of the display module 21 is a high-power consumption state. The high-power consumption state can be any one of charging, power-on, data transmission, and high-performance display, or a state formed by a combination of several of the above states. Correspondingly, when the display module 21 is at the second state control bit 121b, the target state of the display module 21 is a low-power consumption state. The low-power consumption state can be any one of standby, power-off, or low-performance display. When the display function of the display module 21 is not needed, the display module 21 can be moved to the second state control bit 121b, so that the power consumption of the display module 21 is relatively low, and the battery life of the display module 21 can be improved. By setting two state control bits 121 to achieve high-power consumption and low-power consumption target states respectively, it is convenient to switch frequently between high-power consumption and low-power consumption target states, and the number of set state control bits 121 can be reduced, thereby reducing the impact of setting the state control bits 121 on the appearance of the near-eye display device 100.

[0040] When the display module 21 is in a high-power consumption state, its power consumption is relatively fast, which may affect the working stability of the near-eye display device 100. For example, when the display module 21 performs data transmission with other devices, such as firmware upgrade, communication, etc., the display module 21 can communicate with other devices by using a wireless transmission method (such as 2.4g, radio frequency, Bluetooth, WiFi, etc.). The power consumption of the display module 21 is relatively high. If the power is insufficient during data transmission, the data transmission will fail, which will affect the working stability of the near-eye display device 100. In one embodiment, the high-power consumption state includes a charging state and any one or several states formed by a combination of power-on, data transmission, and high-performance display. That is, when the display module 21 is at the first state control bit 121a, the display module 21 can perform other functions with relatively high power consumption in the charging state, so as to timely supplement electric energy for the display module 21, and ensure the working stability of the near-eye display device 100.

[0041] In one embodiment, as Figure 3 shown, the number of set state control bits 121 is multiple. The multiple state control bits 121 are distributed on the outer periphery of the lens 11, and at least one state control bit 121 is arranged outside the viewing area 111 for accommodating the display module 21 when it is in a non-display state. With such a setting, when the display module 21 is not needed, the display module 21 can be moved to the state control bit 121 located outside the viewing area 111, so as to prevent the display module 21 from blocking the viewing line of the lens 11.

[0042] In one embodiment, as Figure 3As shown, there are multiple settings for the status control bits 121, and the multiple status control bits 121 are distributed on the outer periphery of the lens 11. At least one status control bit 121 is arranged within the viewing area 111 for accommodating the display module 21 when in the display state. Arranging at least one status control bit 121 within the viewing area 111 enables the display module 21 to have other states during display, such as a charging state. That is, the user can charge the display module 21 when the display function of the display module 21 is turned on, which can improve the battery life of the display module 21. The status control bit 121 located within the viewing area 111 can be arranged at the outer peripheral part of the viewing area 111, so as to occupy as little of the viewing area 111 as possible and reduce the "foreign object" repulsion feeling of the lens 11.

[0043] In one embodiment, the display module 21 is provided with a trigger member (not shown in the figure), and the status control bit 121 is correspondingly provided with a sensing member (not shown in the figure). When the display module 21 moves to the status control bit 121, the trigger member is configured to trigger the sensing member so that the display module 21 switches to the target state. Optionally, the trigger member is a magnet or a metal contact (one of the male and female connectors), etc. Correspondingly, the sensing member can be a magnetic induction coil, a metal contact (the other of the male and female connectors), or a Hall element, etc. When the display module 21 moves to the status control bit 121, the trigger member is configured to trigger the sensing member to generate an electrical signal or a magnetic signal, and the display module 21 is switched to the target state according to the generated signal. Of course, the setting positions of the trigger member and the sensing member are relative, that is, the sensing member can be arranged on the display module 21, and correspondingly, the trigger member is arranged at the status control bit 121.

[0044] In one embodiment, when the display module 21 moves to the status control bit 121 and stays for a preset duration, the trigger member triggers the sensing member. The preset duration can be 0.1s, 0.5s, 1.0s, 1.5s, 2.0s, 2.5s, 3.0s, etc., and no specific limitation is made here. Setting that the trigger member triggers the sensing member after the display module 21 moves to the status control bit 121 and stays for the preset duration makes it so that when the holding time of the display module 21 moving to the status control bit 121 is less than the preset duration, the state will not be switched. For example, when the display module 21 quickly switches from the second status control bit 121b to the first status control bit 121a, it will not immediately switch to the target state of the display module 21 being in the first status control bit 121a, which can reduce the high power consumption of other electrical components awakened by misoperation, thereby improving the battery life of the display module 21.

[0045] Optionally, the display module 21 is magnetically connected to the lens 11, and the user can manually move the display module 21 so that the display module 21 is located at different positions on the lens 11, or move the display module 21 to the status control bit 121.

[0046] Optionally, please refer toFigure 1 , in one embodiment, the near-eye display device 100 includes a bracket 30. The first end of the bracket 30 is rotatably connected to the frame 12 and / or the lens 11. A display module 21 is mounted at the second end of the bracket 30 relative to the first end. The bracket 30 is configured to drive the display module 21 to move on the lens 11, so that the display module 21 can be driven by the bracket 30 to move to a target position on the lens 11. Exemplarily, the bracket 30 drives the display module 21 to move between the viewing area 111 of the lens 11 and outside the viewing area 111, or the bracket 30 drives the display module 21 to move between the lens 11 and the state control position 121. The rotation of the bracket 30 can be manually adjusted or automatically adjusted, such as electric adjustment or cylinder adjustment, etc. Exemplarily, the user can control the rotation of the bracket 30, and thus control the movement of the display module 21, by pressing a button provided on the frame 12 or by a terminal device (such as a mobile phone, a laptop, etc.) communicatively connected to the near-eye display device 100. With such a setting, when the display module 21 needs to be used, the bracket 30 can drive the display module 21 to move to the viewing area 111 of the lens 11, and the display module 21 can display preset image content to the user's eyes, such as Figure 1 shown; when the display module 21 does not need to be used, the bracket 30 can drive the display module 21 to move to the state control position 121 or outside the viewing area 111 of the lens 11, which can realize the switching of the target state of the display module 21 or prevent the display module 21 from blocking the viewing line of the lens 11, such as Figure 2 shown.

[0047] Optionally, in one embodiment, as Figure 2 shown, the wearing component 10 further includes temple arms 13. The temple arms 13 are connected to the frame 12, and the frame 12 and the temple arms 13 can enclose a wearing space for the user to wear.

[0048] Optionally, the bracket 30 is located on the side of the frame 12 facing the environment, the display module 21 is located on the side of the lens 11 facing the environment and the light-emitting surface of the display module 21 faces the lens 11. The state control position 121 includes a light-transmitting notch that can be transmitted by light from the environment side to the eye side. The light of the display module 21 is configured to be transmitted from the environment side through the light-transmitting notch to the eye side. Setting the bracket 30 on the side of the frame 12 facing the environment makes the operation space for adjusting the bracket 30 outside the wearing space of the wearing component 10, which can facilitate the user to move the position of the display module 21 by operating the bracket 30.

[0049] Optionally, the bracket 30 is located on the side of the housing 12 facing the eye, the display module 21 is located on the side of the lens 11 facing the glasses, and the light-emitting surface of the display module 21 faces away from the lens 11. The state control bit 121 includes an opaque notch that cannot be penetrated by light from the environment side to the glasses side, and the light of the display module 21 is configured to directly enter the glasses side. By arranging the bracket 30 on the side of the housing 12 facing the eye, when the display module 21 is received in the state control bit 121, the housing 12 or the lens 11 can block the bracket 30, and the bracket 30 cannot be observed from the external environment side, which can reduce the influence of the bracket 30 on the appearance of the near-eye display device 100.

[0050] If the user wears the near-eye display device 100 in a moving state (such as walking or running), the display module 21 may slide out of the state control bit 121 when it is impacted or vibrated. Optionally, in an embodiment, the state control bit 121 is provided with a fastener (not shown in the figure), and the fastener includes an elastic deformation member or an adsorbent. At least a part of the side wall of the display module 21 fits with the fastener, so that when the display module 21 is received in the state control bit 121, the fastener fixes the display module 21 in the state control bit 121, and the display module 21 can be prevented from sliding out of the state control bit 121 when it is impacted or vibrated. The fastener can be an elastic snap ring, a rubber ring, a magnetic part, etc.

[0051] Optionally, when the display module 21 is located in the state control bit 121, the projected contour of the bracket 30 on the housing 12 is smaller than the contour of the housing 12 itself. The contour can be the contour corresponding to the position of the housing 12 where the bracket 30 is located, so that the bracket 30 is located within the contour of the housing 12. Among them, the bracket 30 can choose a material with the same or similar color as the housing 12, or the bracket 30 is a transparent material, so that the bracket 30 is not easily observed from the external environment side, which can reduce the influence of the bracket 30 on the appearance of the near-eye display device 100. Optionally, when the display module 21 is located in the state control bit 121, the vertical projection area of the bracket 30 relative to the lens 11 does not overlap with the lens 11. For example, the vertical projection area of the bracket 30 relative to the lens 11 does not overlap with the viewing area 111 of the lens 11. For example, when the bracket is in the state control bit 121, it is just located at the boundary or outside of the viewing area 111, or in the viewing blind area, etc., which can prevent the bracket 30 from blocking the line of sight of the viewing area 111.

[0052] Please refer to Figure 6, in one embodiment, the frame 12 is provided with a bracket storage position 122. The bracket storage position 122 is located at the edge of the lens 11 and communicates with the state control position 121. The length of the bracket storage position 122 is greater than that of the state control position 121, and the bracket 30 is configured to be stored in the bracket storage position 122. The bracket storage position 122 can be a groove formed on the frame 12. The shape and size of the bracket storage position 122 match the outer contour of the bracket 30, so that the bracket 30 can be stored in the bracket storage position 122. When the display module 21 is not needed, the bracket 30 can drive the display module 21 to move, and the display module 21 is stored in the state control position 121, and the bracket 30 is stored in the bracket storage position 122 communicating with the state control position 121. On the one hand, the bracket storage position 122 protects the bracket 30 and can prevent external foreign objects from touching the bracket 30; on the other hand, the bracket 30 can be hidden in the bracket storage position 122, and it is not easy to observe the bracket 30 from the side of the external environment, which can reduce the impact of the bracket 30 on the appearance of the near-eye display device 100.

[0053] Generally speaking, the surface of the lens 11 is usually an arc surface with a certain curvature, that is, the surface of the lens 11 is not flat. When the bracket 30 moves within the range of the lens 11, the mutual contact between the two may cause frictional damage to the lens 11. In one embodiment, the surface of the bracket 30 facing the lens 11 is complementary to the surface of the lens 11. Exemplarily, the surface of the lens 11 is an arc surface, and the surface of the bracket 30 facing the lens 11 is also an arc. Such a setting makes the bracket 30 adapt to the surface of the lens 11 and can prevent the bracket 30 from causing frictional damage to the lens 11.

[0054] Optionally, in one embodiment, the bracket 30 and a part of the display module 21 are attached to the lens 11, and a buffer layer (not shown in the figure) is provided on the surface of the bracket 30 and the display module 21 that is attached to the lens 11. The buffer layer can be a flexible material such as plastic, silica gel, or fiber cotton. By providing the buffer layer, the frictional damage to the lens 11 caused by the movement of the bracket 30 and the display module 21 on the lens 11 can be reduced.

[0055] Optionally, in one embodiment, a cleaning layer (not shown in the figure) is provided on the surface of the bracket 30, the display module 21 that is attached to the lens 11. When the bracket 30 and the display module 21 move relative to the lens 11, the cleaning layer can clean the lens 11. The cleaning layer can be fiber cotton. The cleaning layer wipes the lens 11 to keep the lens 11 clean and convenient for the user to view the external environment.

[0056] Optionally, a buffer layer and a cleaning layer are simultaneously provided on the surface of the bracket 30, the display module 21 that is attached to the lens 11. When the bracket 30 and the display module 21 move on the lens 11, the buffer layer can reduce the frictional damage of the bracket 30 and the display module 21 to the lens 11, and the cleaning layer can clean the lens 11.

[0057] In one embodiment, as Figure 7 shown, the bracket 30 includes a rotating shaft 31, a first telescopic rod 32, and a second telescopic rod 33. One end of the first telescopic rod 32 is rotatably connected to the frame 12 and / or the lens 11 through the rotating shaft 31. The opposite end of the first telescopic rod 32 is telescopically connected to the second telescopic rod 33. The display module 21 is installed at the end of the second telescopic rod 33 away from the first telescopic rod 32. By setting the first telescopic rod 32 to be rotatably connected to the frame 12 and the second telescopic rod 33 to be telescopically connected to the first telescopic rod 32, the display module 21 has two degrees of freedom relative to the lens 11. By rotating the first telescopic rod 32 and / or pushing and pulling the second telescopic rod 33, the relative position between the display module 21 and the lens 11 can be changed, so that the display module 21 can be adjusted to the best viewing position according to the user's needs to meet different usage requirements of the user.

[0058] The rotational adjustment of the first telescopic rod 32 and the telescopic adjustment between the second telescopic rod 33 and the first telescopic rod 32 can be manual adjustment. Of course, it can also be automatic adjustment, such as electric adjustment or cylinder adjustment, etc. Exemplarily, the user can control the movement of the first telescopic rod 32 and the second telescopic rod 33 through the buttons provided on the frame 12, and further control the movement of the display module 21; or the user controls the movement of the display module 21 through a terminal device (such as a mobile phone, a laptop, etc.) communicatively connected to the near-eye display device 100.

[0059] Optionally, the first telescopic rod 32 and the second telescopic rod 33 are made of a transparent material, so that it is not easy to observe the bracket 30 from the outside environment side, which can reduce the influence of the bracket 30 on the appearance of the near-eye display device 100.

[0060] Optionally, the display module 21 is a module that can work independently, that is, the display module 21 is built-in with electronic devices such as a battery and a circuit board. In some other embodiments, electronic devices such as a battery and a circuit board can also be arranged in the frame 12, and the display module 21 is connected to the electronic devices in the frame 12. For example, the bracket 30 is hollow, and an electrical wire is arranged therein, and the wire is electrically connected to the electronic devices in the frame 12 and the display module 21. Optionally, an electrical component is provided on the temple 13. The first telescopic rod 32 and the second telescopic rod 33 include a communicating hollow cavity, and an electrical wire is arranged in the hollow cavity. The display module 21 is electrically connected to the electrical component through the electrical wire. By providing a hollow cavity in the first telescopic rod 32 and the second telescopic rod 33, the wire can be hidden in the hollow cavity, thereby avoiding the wire from being exposed and affecting the appearance of the near-eye display device 100.

[0061] In one embodiment, as Figure 8As shown, the display component 20 includes a detection module 22 and a control module 23. The detection module 22 is used to obtain a representative value of the motion parameters when the display module 21 moves on the lens 11. There is a preset corresponding relationship between the representative value of the motion parameters and multiple applications. The control module 23 is configured to control the display module 21 to display the target application according to the corresponding relationship. Optionally, the representative value of the motion parameters is the moving speed or acceleration of the display module 21 relative to the wearing component 10. Optionally, the detection module 22 is an Inertial Measurement Unit (IMU) or an attitude sensor. The above detection devices can accurately detect the representative value of the motion parameters when the display module 21 moves on the lens 11, so as to provide a basis for the control module 23 to control the display module 21. Exemplarily, the target application can be an instant messaging application, a map application, a music application, an album application, etc. By obtaining the representative value of the motion parameters of the display module 21 and then controlling the display module 21 to display the target application, the opening of the target application is convenient and fast, which can improve the user experience.

[0062] Optionally, when the support 30 drives the display module 21 to move on the lens 11, the representative value of the motion parameters is one of the displacement of the display module 21, the displacement component of the displacement in a preset direction, the rotation angle, the length of the support, etc., or a combination of some of the above representative values of the motion parameters. Compared with other representative values of motion parameters (such as moving speed or acceleration), the acquisition of the above representative values of motion parameters is more convenient, which can reduce the cost of the near-eye display device 100.

[0063] Please refer to Figures 9 - 11 , in an embodiment, a motion reference position is set on the frame 12 and / or the lens 11. Optionally, the motion reference position is one of the state control positions 121. The representative value of the motion parameters includes the displacement of the display module 21 relative to the motion reference position when the support 30 drives the display module 21 to move on the lens 11 (such as Figure 11 shown as d), or the displacement component of the displacement in a preset direction (such as Figure 9 or Figure 10 shown as x or y). There is a preset corresponding relationship between the displacement or displacement component and multiple applications. Exemplarily, as Figure 11 shown, the displacement is a vector. According to the different displacements, the lens 11 is divided into multiple regions in the longitudinal and transverse directions, and each region corresponds to an application. For example, region 1 corresponds to an instant messaging application, region 2 corresponds to a map application, region 3 corresponds to a music application, and region 4 corresponds to an album application. Of course, according to the different displacement components of the displacement in a preset direction, for example, the preset direction is vertical, the lens 11 can be divided into multiple regions in the longitudinal direction, as Figure 9 shown; or the preset direction is horizontal, the lens 11 can be divided into multiple regions in the transverse direction, as Figure 10As shown, each region corresponds to an application. According to different representative values of the motion parameters, the display module 21 is located in different regions, and the control module 23 controls the display module 21 to display the target application according to the corresponding relationship. For example, if the display module 21 is located in region 1, the display module 21 displays an instant messaging application; if the display module 21 is located in region 3, the display module 21 displays a music application.

[0064] In one embodiment, as shown in Figures 12 - 14 a motion reference line is provided on the frame body 12 and / or the lens 11. Optionally, the motion reference line is a connection line between the position of the rotating shaft 31 and the state control position 121 when the bracket 30 is located at one of the state control positions 121, that is, the position where the axis of the bracket 30 is located at this time. The representative value of the motion parameter includes the rotation angle of the bracket 30 relative to the motion reference line when the bracket 30 drives the display module 21 to move on the lens 11 (such as Figure 12 , Figure 14 shown as α) and / or the bracket length (such as Figure 12 , Figure 13 shown as l). The rotation angle and / or the bracket length have a preset corresponding relationship with multiple applications, and the control module 23 controls the display module 21 to display the target application according to the corresponding relationship. Optionally, according to different rotation angles, the lens 11 is divided into multiple regions in the rotation direction of the bracket 30, as shown in Figure 12 ; or according to different bracket lengths, the lens 11 is divided into multiple regions in the telescopic direction of the bracket 30, as shown in Figure 13 ; or according to different rotation angles and bracket lengths, the lens 11 is divided into multiple regions in the rotation direction and the telescopic direction of the bracket 30, as shown in Figure 14 , and each region corresponds to an application. When the display module 21 is located in different regions, the control module 23 controls the display module 21 to display the target application according to the corresponding relationship.

[0065] The present application also provides a control method for a near-eye display device. The near-eye display device includes a display module 21 and a frame body 12. The display module 21 is used to display preset image content. A lens 11 is installed on the frame body 12. The lens 11 has a viewing area, and the user's eyes can observe the external environment side through the viewing area 111 from the eye side. A state control position 121 is provided on the frame body 12 and / or the lens 11.

[0066] Please refer to Figure 15 , the control method 500 includes steps S510 - S530:

[0067] S510, obtain the position distribution of the state control position 121 on the frame body 12 and / or the lens 11.

[0068] The number of settings of the status control bit 121 can be one or multiple. When the number of settings of the status control bit 121 is one, the user can customize the target status implemented by the status control bit 121. For example, according to different requirements in different usage periods, the user can change the target status implemented by the status control bit 121. When the number of settings of the status control bit 121 is multiple, the target status implemented by each status control bit 121 can be different. By obtaining the position distribution of the status control bits 121 on the frame 12 and / or the lens 11, it can be used to establish the correspondence between each status control bit 121 and the target status that can be achieved, and the correspondence can be pre-stored in the storage device of the near-eye display device 100.

[0069] S520, determine the moving position of the display module 21 on the lens 11.

[0070] Specifically, when the display module 21 moves on the lens 11 and stays at a certain position, it is determined whether the position where the display module 21 is located is within the viewing area 111 of the lens 11, outside the viewing area 111, or at a certain status control bit 121, so as to provide a basis for subsequent control operations.

[0071] S530, when the moving position of the display module 21 is located in the position distribution of the status control bit 121, the display module 21 is configured to switch to the target status.

[0072] Optionally, the target status of the display module 21 is switched according to the correspondence between the status control bit 121 and the target status that can be achieved. Of course, it can also be that after the display module 21 is located at the status control bit 121, the user sets the target status of the display module 21 in a customized manner, so as to realize the switching of the target status of the display module 21.

[0073] In an embodiment, when the display module 21 moves to a preset area on the lens 11, the control method 500 can control the display module 21 to display the target application. Please refer to Figure 16 , the control method 500 includes steps S510 - S530:

According to the different motion parameter representative values, the lens 11 can be divided into multiple regions longitudinally and / or transversely, or the lens 11 can be divided into multiple regions in the rotation direction and / or the telescopic direction of the bracket 30, and each region corresponds to an application, so as to establish a correspondence between the motion parameter representative value and multiple applications. The correspondence can be pre-stored in the storage device of the near-eye display device 100.

[0076] S520, the detection module 22 obtains the motion parameter representative value when the display module 21 moves on the lens 11, and transmits the motion parameter representative value to the control module 23.

[0077] The detection module 22 can be an inertial measurement unit or an attitude sensor. When the display module 21 moves on the lens 11, the detection module 22 can detect and obtain the motion parameter representative value of the display module 21, so as to provide a basis for the control module 23 to control the display module 21.

[0078] S530, the control module 23 receives the motion parameter representative value, and controls the display module 21 to display the target application according to the correspondence between the motion parameter representative value and multiple applications. According to the different motion parameter representative values, the display module 21 is located in different regions, and the control module 23 controls the display module 21 to display the target application according to the correspondence, so that the opening of the target application is convenient and fast, and the user experience can be improved.
