Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent head-mounted display glasses, more particularly to a display system centering device and method for intelligent head-mounted display glasses. BACKGROUND

[0002] Intelligent head-mounted display glasses guide the video image light emitted by a miniature image display (such as a transmissive or reflective liquid crystal display screen, an organic electroluminescent device, a DMD device) to the pupil of a user through optical technology to realize a virtual, enlarged image in the near vision range of the user, thereby providing the user with intuitive, visual 2D / 3D images, videos and text information.

[0003] The existing intelligent head-mounted display glasses have imaging blur, especially edge imaging blur, mainly because the axial alignment matching degree of the optical system and the display system of the intelligent head-mounted display glasses is not enough, which causes dizziness and eye fatigue of the user after long-term wearing and use.

[0004] To solve the above problems, in the prior art, the optical lens and the display screen are accurately aligned during the production of the intelligent head-mounted display glasses to ensure the imaging effect of the display screen in the intelligent head-mounted display glasses. Patent document (Chinese patent CN106054392B) discloses an alignment method of an optical lens and a display screen in a VR device. The method generates a test pattern on the display screen, an image acquisition device acquires the test pattern imaged on the optical lens to obtain a correction pattern, and an algorithm is used to determine whether the correction pattern coincides with a preset reference pattern. If not, the relative position of the optical lens and the display screen is adjusted until they coincide. However, the alignment method mainly determines whether the correction pattern coincides with the reference pattern through an algorithm. Each time the relative position of the optical lens and the display screen is adjusted, the image needs to be acquired and the algorithm needs to be determined, which makes the alignment process more complex, resulting in complicated production process of the intelligent head-mounted display glasses, troublesome product post-maintenance and high overall process cost.

DETAILED DESCRIPTION

[0052] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the following will combine the technical scheme in the embodiments of the present application to make a clear and complete description. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0053] Embodiment one

[0054] The display system centering device for the intelligent head-mounted display glasses according to the embodiment one of the present application, as shown in Figure 1 and Figure 2 comprises:

[0055] The display assembly 1 is mounted with the display screen 8;

[0056] The alignment assembly 2 is prepared according to the optical parameters of the intelligent head-mounted display glasses, and the alignment assembly 2 is assembled with the display assembly 1;

[0057] The fixing unit 3 is used for mounting the display assembly 1;

[0058] The image acquisition unit 4 is used for shooting the assembled display assembly 1 and the alignment assembly 2 to obtain a real-time enlarged display picture;

[0059] The correction unit 5 is used to move and / or rotate the display screen 8 in parallel until the display screen 8 is aligned with the alignment assembly 2 according to the enlarged display picture;

[0060] The UV curing unit 6 is used to glue and cure the display assembly 1 after alignment.

[0061] The electric control system 7 is electrically connected with the core adjusting assembly and the UV curing assembly respectively.

[0062] The alignment assembly 2 is pre-processed according to the optical parameters of the smart head-mounted display glasses, and then assembled with the display assembly 1 and fixed on the fixing unit 3. The image acquisition unit 4 is located directly above the display assembly 1 and the alignment assembly 2, and captures the assembled display assembly 1 and alignment assembly 2 in real time to obtain a real-time enlarged display picture. The staff moves and / or rotates the display screen 8 in the display assembly 1 in parallel using the correction unit 5 according to the enlarged display picture, so that the display screen 8 is aligned with the alignment assembly 2, and at this time the center of the optical system is aligned with the center of the display screen 8. The UV curing unit 6 has two processes of temporary curing and final curing. In the temporary curing process, the display assembly 1 is glued and cured along the part not blocked by the alignment assembly 2. In the final curing process, the alignment assembly 2 is removed, and the remaining part of the display assembly 1 is glued and cured. The production of the display system of the smart head-mounted display glasses is completed, and the center of the display system is aligned with the axis of the optical system.

[0063] The application adopts a modular process to align the center of the display system with the axis of the optical system in the production stage of the display system, solves the problem that the high-precision positioning process of the display screen 8 cannot be achieved in most existing optical integrated designs, and is different from other smart head-mounted glasses in that the alignment is performed in the later stage. This greatly simplifies the complicated production process, optimizes the process of product production and maintenance in the later stage, and reduces the overall process cost.

[0064] In further embodiments, as shown in Figure 11 The correction hole 21 is provided in the alignment assembly 2 corresponding to the display screen 8; when the display assembly 1 is centered, the edge of the display screen 8 coincides with the edge of the correction hole 21.

[0065] The correction hole 21 is pre-processed according to the optical parameters and requirements of the optical system, and when the alignment assembly 2 is aligned with the display screen 8, the edge of the display screen 8 coincides with the edge of the correction hole 21.

[0066] The left and right eye display screens 8 correspond to left and right alignment assemblies 2 respectively, the left and right alignment assemblies 2 are of the same structure but different sizes, and the purpose is to make the display screen 8 center offset. The design is because when the user watches 3D movie, the 3D effect is achieved through the left and right screens or the upper and lower screens superposition, and the display screen 8 center offset is more in line with the principle of human imaging fusion. However, the center of the display screen 8 is completely opposite to the optical system axis, which is not conducive to binocular fusion imaging. Therefore, the center of the left alignment assembly 2 is right shifted 0.13mm relative to the optical axis center, and the center of the right alignment assembly 2 is left shifted 0.13mm relative to the optical axis center, which is more conducive to binocular fusion imaging of human eyes.

[0069] When the alignment assembly 2 is assembled with the display assembly 1, the first positioning hole 23 and the second positioning hole 13 are aligned and matched, which can ensure that the alignment assembly 2 is correctly installed in the display assembly 1 and positioned. The frame of the mounting position 12 is higher than the bottom surface of the first recess 11, and the protruding portion 22 is horizontally abutted on the bottom surface of the first recess 11 on both sides of the mounting position 12, which can ensure that the alignment surface of the alignment assembly 2 is almost abutted with the surface of the display screen 8.

[0070] In the above embodiments, the first positioning hole 23 and the second positioning hole 13 are both two, one of the first positioning hole 23 and the second positioning hole 13 is a circular hole, and the other of the first positioning hole 23 and the second positioning hole 13 is an elliptical hole, which is to avoid difficult alignment during installation.

[0109] Compared with the first embodiment, the second embodiment adds a process of checking whether the edge of the display screen 8 after gluing coincides with the edge of the correction hole 21, so that the alignment accuracy of the optical system axis of the smart head-mounted display glasses and the center of the display system is higher.

[0110] The present application adopts a modular process, and realizes the alignment of the center of the display system and the optical system axis in the production stage of the display system, solves the problem that the high-precision positioning process of the display screen 8 cannot be achieved in most existing optical integration designs, which is different from the alignment of other smart head-mounted glasses in the later stage. This greatly simplifies the complicated production process, optimizes the process of product production and maintenance in the later stage, and reduces the overall process cost.

[0111] In a further embodiment, a detection unit 9 is further included; the image acquisition unit 4 is arranged on the detection unit 9; the detection unit 9 includes a second rack and a second workbench arranged on the second rack; and the second workbench is provided with a second movable positioning member.
