When the complex light in the external environment (such as indoor lighting or outdoor sunlight) shines on these grating areas, it will be diffracted into rainbow patterns and then enter the human eye. The appearance of rainbow patterns not only seriously interferes with the user's vision, but also affects the user's viewing experience of virtual display content and the real world, reduces the comfort of the device, and makes it difficult for users to wear it for a long time.

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0032] See also Figure 1 , Figure 1 The figure is a schematic diagram of the structure of a near-eye display device in the prior art. Near-eye display devices are considered to be the best terminal carrier for the application of "AR+AI" technology and have attracted widespread attention. Figure 1 The existing near-eye display device 1 mainly includes two parts: a micro-projection optical machine 2 and an optical coupler 3. The optical coupler 3 has the advantages of being thin, light, transparent, and easy to industrially design, which is far lower than other technical solutions. It is considered to be the mainstream optical coupler 3 solution in the future. The optical coupler 3 usually contains a one-dimensional or two-dimensional diffraction grating 31. This type of diffraction grating 31 has a significant dispersion effect. When the complex light in the external environment (indoor lights or outdoor sunlight, etc.) shines on these grating areas, it will be dispersed into rainbow patterns by the diffraction grating 31 and enter the human eye. The existence of rainbow patterns will seriously interfere with the user's line of sight, affect the user's viewing of virtual display content and the real world, greatly reduce the user's experience, and make it difficult to wear for a long time.

[0033] Therefore, the embodiments of the present application provide an optical component and a near-eye display device, which can reduce the rainbow pattern, thereby reducing the impact of the rainbow pattern on the user and improving the user experience.

[0034] See also Figure 2 , Figure 2 A schematic diagram of the first structure of an optical component provided in an embodiment of the present application. An embodiment of the present application provides an optical component 20, which includes an optical coupler 21 and a reflective film layer 22. The optical coupler 21 includes a waveguide substrate 211, an in-coupling grating 212, and an out-coupling grating 213, wherein the in-coupling grating 212 and the out-coupling grating 213 are arranged on the waveguide substrate 211, and the optical coupler 21 is configured to conduct image light signals and transmit ambient light. The reflective film layer 22 is arranged corresponding to the out-coupling grating 213.

[0035] The material of the waveguide substrate 211 can be any colorless transparent medium, preferably glass and plastic. The waveguide substrate 211 in the optical coupler 21 can be a flat plate structure with a certain thickness. The flat plate structure has a first surface and a second surface relative to each other. The coupling-in grating 212 and the coupling-out grating 213 can be both arranged on the same surface, for example, both arranged on the first surface or the second surface. The coupling-in grating 212 and the coupling-out grating 213 can be arranged on the first surface and the second surface, respectively.

[0036] The coupling-in grating 212 and the coupling-out grating 213 may be diffraction gratings. Specifically, the coupling-in grating 212 on the optical coupler 21 receives the image light signal and converts the image light signal into diffraction light, which is totally reflected in the waveguide substrate 211 and then emitted to the human eye through the coupling-out grating 213.

[0037] Ambient light can directly enter the human eye through the coupling grating 212 and the waveguide substrate 211, and then the image light signal and the ambient light enter the user's eye together, providing the user with a sensory experience of combining virtuality and reality. The ambient light includes a first light and a second light, and the incident angle of the first light relative to the reflective film layer 22 is greater than the incident angle of the second light relative to the reflective film layer 22. In order to avoid the generation of rainbow spots by large-angle light in the ambient light, such as the first light, it is also necessary to ensure that small-angle light in the ambient light, such as the second light, enters the human eye normally to maintain normal use function (without affecting the brightness of the ambient light entering the eye). A reflective film layer 22 is also provided in the optical component 20, and the reflective film layer 22 is arranged corresponding to the coupling grating 213, that is, the reflective film layer 22 is arranged on the propagation path of the ambient light entering the human eye, and the reflective film layer 22 can reflect the first light and transmit the second light. It can be understood that the reflectivity of the reflective film layer 22 to the first light is greater than the reflectivity to the second light. The reflection of the first light means that the first light that will generate the rainbow pattern problem is reflected and the rainbow pattern problem is eliminated. While ensuring that users can view the environment scenes normally, it can reduce the impact of rainbow patterns on users, thereby improving the user experience.

[0038] The first light and the second light in the ambient light may be defined as an incident angle of 30 to 60 degrees relative to the reflective film layer 22. For example, the incident angle of the first light relative to the reflective film layer 22 is greater than or equal to 30 degrees, and the incident angle of the second light relative to the reflective film layer 22 is less than 30 degrees; for another example, the incident angle of the first light relative to the reflective film layer 22 is greater than or equal to 60 degrees, and the incident angle of the second light relative to the reflective film layer 22 is less than 60 degrees. Specific parameters can be set according to the user's usage scenario.

[0039] In some cases, please continue to see Figure 2, when the coupling-in grating 212 and the coupling-out grating 213 are both arranged on the same side of the waveguide substrate 211, the reflective film is arranged on the side of the waveguide substrate 211 away from the coupling-in grating 212 and the coupling-out grating 213. In this way, the waveguide substrate 211 can carry both the coupling-in grating 212 and the coupling-out grating 213 and the reflective film, and the reflective film will not interfere with the normal function of the coupling-in grating 212 and the coupling-out grating 213, and the reflective function of the reflective film can ensure the total reflection function of the waveguide substrate 211, thereby improving the effect of the optical coupler 21.

[0040] In some embodiments, see Figure 3 as well as Figure 4 , Figure 3 A second structural schematic diagram of an optical component provided in an embodiment of the present application, Figure 4 The third structural schematic diagram of the optical component provided in the embodiment of the present application. The optical component 20 further includes a first cover plate 23, the first cover plate 23 is arranged on the side of the waveguide substrate 211 where the coupling-in grating 212 is arranged, and the reflective film layer 22 is arranged on the side of the first cover plate 23 close to the waveguide substrate 211 or the reflective film layer 22 is arranged on the side of the first cover plate 23 away from the waveguide substrate 211.

[0041] The first cover plate 23 can prevent dust and oil from adhering to the optical coupler 21. Further, the orthographic projection of the first cover plate 23 on the waveguide substrate 211 coincides with the boundary of the waveguide substrate 211, that is, the first cover plate 23 and the waveguide substrate 211 have the same shape, and can completely cover the waveguide substrate 211, thereby more comprehensively protecting the coupling-in grating 212 and / or the coupling-out grating 213 in the optical coupler 21.

[0042] The first cover plate 23 has a third surface and a fourth surface opposite to each other, wherein the third surface is a side of the first cover plate 23 close to the waveguide substrate 211, and the fourth surface is a side of the first cover plate 23 away from the waveguide substrate 211. The reflective film layer 22 is disposed on the third surface or the fourth surface, so that the first cover plate 23 can protect the optical coupler 21 and also carry the reflective film layer 22, and can also simplify the process of disposing the reflective film layer 22 on the first cover plate 23, thereby improving the manufacturing efficiency.

[0043] The optical assembly 20 further includes a plastic frame (referred to as a first plastic frame 24), which is disposed at the edges of the waveguide substrate 211 and the first cover plate 23 to fix the relative positions of the waveguide substrate 211 and the first cover plate 23. The first plastic frame 24 may be a circular ring structure with a certain thickness, so that the first plastic frame 24, the waveguide substrate 211 and the first cover plate 23 can form a closed space, thereby preventing dust from entering between the waveguide substrate 211 or the first cover plate 23.

[0044] In addition, since the first rubber frame 24 has a certain thickness, there is a certain distance between the waveguide substrate 211 and the first cover plate 23 , so that the first cover plate 23 can protect the waveguide substrate 211 and prevent the waveguide substrate 211 from being worn due to contact and friction with the first cover plate 23 .

[0045] The material of the first adhesive frame 24 is optical adhesive. The optical adhesive can be OCA (Optically Clear Adhesive) or OCR (Optical Clear Resin). The OCR adhesive is also called liquid optical clear adhesive. Optical adhesive has the advantages of high cleanliness, high light transmittance, strong adhesion, water and high temperature resistance, UV resistance, and low curing shrinkage.

[0046] In some embodiments, see Figure 5 as well as Figure 6 , Figure 5 A fourth structural schematic diagram of an optical component provided in an embodiment of the present application, Figure 6 The fifth structural schematic diagram of the optical component provided in the embodiment of the present application. The optical component 20 further includes a second cover plate 25, which is disposed on a side of the waveguide substrate 211 away from the coupling-in grating 212, and the reflective film layer 22 is disposed on a side of the second cover plate 25 close to the waveguide substrate 211 or on a side of the second cover plate 25 away from the waveguide substrate 211.

[0047] The second cover plate 25 can prevent dust and oil from adhering to the optical coupler 21. Further, the orthographic projection of the second cover plate 25 on the waveguide substrate 211 coincides with the boundary of the waveguide substrate 211, that is, the second cover plate 25 has the same shape as the waveguide substrate 211, and can completely cover the waveguide substrate 211, thereby more comprehensively protecting the waveguide substrate 211, the coupling-in grating 212 and / or the coupling-out grating 213 in the optical coupler 21.

[0048] The second cover plate 25 has a fifth surface and a sixth surface opposite to each other, wherein the fifth surface is a side of the second cover plate 25 close to the waveguide substrate 211, and the sixth surface is a side of the second cover plate 25 away from the waveguide substrate 211. The reflective film layer 22 is disposed on the fifth surface or the sixth surface, so that the second cover plate 25 can protect the optical coupler 21 and carry the reflective film layer 22, and can also simplify the process of disposing the reflective film layer 22 on the second cover plate 25, thereby improving the manufacturing efficiency.

[0049] The optical assembly 20 further includes a rubber frame (referred to as a second rubber frame 26), which is disposed at the edges of the waveguide substrate 211 and the second cover plate 25, and is used to fix the relative positions of the waveguide substrate 211 and the second cover plate 25. The second rubber frame 26 may be a circular ring structure with a certain thickness, so that the second rubber frame 26, the waveguide substrate 211, and the second cover plate 25 can form a closed space, and dust can be prevented from entering between the waveguide substrate 211 or the second cover plate 25.

[0050] In addition, since the second rubber frame 26 has a certain thickness, there is a certain distance between the waveguide substrate 211 and the second cover plate 25 , so that the second cover plate 25 can protect the waveguide substrate 211 and prevent the waveguide substrate 211 from being worn due to contact and friction with the second cover plate 25 .

[0051] The material of the second adhesive frame 26 is optical adhesive, which may be OCA or OCR.

[0052] In some embodiments, please refer to Figure 7 The optical assembly 20 further includes a front shielding lens 27, which is spaced apart from the optical coupler 21; and a reflective film layer 22 is disposed on the front shielding lens 27. The front shielding lens 27 is used to reduce the interference of rainbow patterns, protect the optical coupler 21, and provide different light transmittances to meet the needs of different external environments.

[0053] The front shield lens 27 is usually designed with magnetic attraction, and different lenses can be replaced to adapt to different light environments. In other words, the front shield lens 27 is easy to disassemble and replace. It is understandable that the reflective film is set on the front shield lens 27 so that the user can wear it selectively, so that the user can use the front shield lens 27 when the rainbow pattern needs to be blocked.

[0054] In some embodiments, the reflective film layer 22 includes at least one tantalum pentoxide film and at least one silicon dioxide film, and the tantalum pentoxide film and the silicon dioxide film are alternately stacked to form a reflective mirror layer. The thickness of the reflective film layer 22 is less than or equal to 3 μm, and the reflective film layer 22 can be disposed on the optical coupler 21 or the front lens 27 by using a thin film deposition process such as physical vapor deposition (PVD) and chemical vapor deposition (CVD).
