The temples are connected to the frames, and the lenses are mounted on the frames. At this time, the lenses act as optical elements. The lenses include a first lens layer and a second lens layer connected to each other. The first lens layer and the second lens layer are both subjected to pressure from the corresponding bonding platform and undergo bending deformation under this pressure.

At this time, the first lens layer and the second lens layer have a rebound force in the bent state. The first lens layer and the second lens layer are prone to rebound under the rebound force, which affects the bending accuracy of the first lens layer and the second lens layer.

This method can be applied to electronic devices, including but not limited to wearable devices such as AR (Augmented Reality), VR (Virtual Reality), and MR (Mixed Reality) electronic devices.

[0060] Please refer to Figure 1 and Figure 2 The method for attaching the concave platform frame of the lens includes at least steps S110 to S130, which are described in detail below (the following description uses the application of this method to a wearable device as an example):

[0061] In step S110, the first lens layer 214 is built into the first concave platform 211 and connected to the first concave platform 211 and the first adsorption member 213; the second lens layer 224 is built into the second concave platform 221 and connected to the second concave platform 221 and the second adsorption member 223.

[0062] In the embodiments of this application, the groove of the first concave platform 211 serves as the receiving space for the first lens layer 214. The first lens layer 214 is built into the first concave platform 211 and connects the first concave platform 211 and the first adsorption member 213, so that the first lens layer 214 can be bent and deformed in the groove of the first concave platform 211, thereby ensuring that the bending and deformation of the first lens layer 214 is restricted by the first concave platform 211.

[0063] The groove of the second concave platform 221 serves as the receiving space for the second lens layer 224. The second lens layer 224 is built into the second concave platform 221 and connected to the second concave platform 221 and the second adsorption member 223, so that the second lens layer 224 can be bent and deformed in the groove of the second concave platform 221, thereby ensuring that the bending and deformation of the second lens layer 224 is restricted by the second concave platform 221.

[0064] The specific steps are as follows:

[0065] Step S111: The first lens layer 214 is located in the groove of the first concave platform 211. The first sidewall forming the groove in the first concave platform 211 is connected to the first region 2141 of the first lens layer 214 through the first elastic pad 212.

[0066] In the embodiments of this application, the first lens layer 214 is located in the groove of the first concave platform 211 and is bent and deformed in the groove of the first concave platform 211. The first sidewall forming the groove in the first concave platform 211 is connected to the first region 2141 of the first lens layer 214 through the first elastic pad 212. At this time, the two sides of the first elastic pad 212 are respectively connected to the first sidewall forming the groove in the first concave platform 211 and the first region 2141 of the first lens layer 214, thereby realizing the connection between the first lens layer 214 and the first concave platform 211. At this time, the first region 2141 is the non-central region of the first lens layer 214.

[0067] In step S112, the first adsorption member 213 passes through the first concave platform 211 and is connected to the third region 2142 of the first lens layer 214.

[0068] In an embodiment of this application, the first adsorption member 213 passes through the first concave platform 211 and acts on the first lens layer 214 located in the groove of the first concave platform 211. At this time, the first adsorption member 213 is connected to the third region 2142 of the first lens layer 214, and the adsorption end of the first adsorption member 213 is attached to the third region 2142 of the first lens layer 214. Optionally, the third region 2142 of the first lens layer 214 is the middle region of the first lens layer 214, so that the middle part of the first lens layer 214 is subjected to the adsorption force of the first adsorption member 213, and the non-middle region is subjected to the pressure of the first concave platform 211, thereby facilitating the bending of the first lens layer 214.

[0069] Step S113: The second lens layer 224 is located in the groove of the second concave platform 221. The second sidewall of the groove formed in the second concave platform 221 is connected to the second region 2241 of the second lens layer 224 through the second elastic pad 222.

[0070] In the embodiments of this application, the second lens layer 224 is located in the groove of the second concave platform 221 and is bent and deformed in the groove of the second concave platform 221. The second sidewall forming the groove in the second concave platform 221 is connected to the second region 2241 of the second lens layer 224 through the second elastic pad 222. At this time, the two sides of the second elastic pad 222 are respectively connected to the second sidewall forming the groove in the second concave platform 221 and the second region 2241 of the second lens layer 224, thereby realizing the connection between the second lens layer 224 and the second concave platform 221. At this time, the second region 2241 is the non-central region of the second lens layer 224.

[0071] In step S114, the second adsorption member 223 passes through the second concave platform 221 and is connected to the fourth region 2242 of the second lens layer 224.

[0072] In an embodiment of this application, the second adsorption member 223 passes through the second concave platform 221 and acts on the second lens layer 224 located in the groove of the second concave platform 221. At this time, the second adsorption member 223 is connected to the fourth region 2242 of the second lens layer 224, and the adsorption end of the second adsorption member 223 is attached to the fourth region 2242 of the second lens layer 224. Optionally, the fourth region 2242 of the second lens layer 224 is the middle region of the second lens layer 224, so that the middle part of the second lens layer 224 is subjected to the adsorption force of the second adsorption member 223, and the non-middle region is subjected to the pressure of the second concave platform 221, thereby facilitating the bending of the second lens layer 224.

[0073] After the first lens layer 214 is built into the first concave platform 211 and connected to the first concave platform 211 and the first suction member 213; and the second lens layer 224 is built into the second concave platform 221 and connected to the second concave platform 221 and the second suction member 223, the concave platform frame attachment method for the lens further includes:

[0074] The first concave platform 211 is connected to the first moving member, the first adsorption member 213 is connected to the third moving member, and the adsorption portion between the first adsorption member 213 and the first lens layer 214 is located in the first groove of the first concave platform 211; the first moving member and the third moving member are controlled independently.

[0075] The first and third moving components control the movement of the first concave platform 211 and the first suction component 213, respectively, to control the movement of the first lens layer 214. The suction portion between the first suction component 213 and the first lens layer 214 is located within the first groove of the first concave platform 211, which is connected by a first elastic pad 212. In this configuration, the first and third moving components are controlled independently, and the force on the first lens layer 214 can be adjusted by adjusting the first and third moving components.

[0076] Alternatively, the second concave platform 221 is connected to the second moving member, the second adsorption member 223 is connected to the fourth moving member, and the adsorption portion between the second adsorption member 223 and the second lens layer 224 is located in the second groove of the second concave platform 221; the second moving member and the fourth moving member are controlled independently.

[0077] The second and fourth moving parts control the movement of the second concave platform 221 and the second suction member 223, respectively, to control the movement of the second lens layer 224. The suction portion between the second suction member 223 and the second lens layer 224 is located within the second groove of the second concave platform 221, which is connected by a second elastic pad 222. In this configuration, the second and fourth moving parts are independently controlled, and the force on the second lens layer 224 can be adjusted by adjusting the second and fourth moving parts.

[0078] In one embodiment, the optical module of the augmented reality (AR) near-eye display device includes an optical engine (or light engine) and a light combiner. The light combiner can directionally transmit the signal light emitted from the optical engine to the human eye to form an image to be displayed on the retina. The light combiner includes a first lens layer 214 and a second lens layer 224. The first lens layer 214 and the second lens layer 224 are waveguide layers or protective layers. The waveguide layer is used for light conduction, and the protective layer is used to prevent steam or dust from entering and to block the influence of external light.

[0079] refer to Figure 3 In step S120, as the first concave platform 211 and / or the second concave platform 221 move, the first lens layer 214 and the second lens layer 224 are connected by adhesive 230. At this time, the inner wall of the first concave platform 211 restricts the first lens layer 214, and the inner wall of the second concave platform 221 restricts the second lens layer 224.

[0080] In the embodiments of this application, as the first concave platform 211 and / or the second concave platform 221 move, the distance between the first lens layer 214 and the second lens layer 224 gradually decreases, so that the first lens layer 214 and the second lens layer 224 can approach each other, thereby connecting the first lens layer 214 and the second lens layer 224 by the adhesive 230. At this time, the inner sidewall of the first concave platform 211 restricts the first lens layer 214 to limit the bending of the first lens layer 214 and maintains pressure on the first lens layer 214, while the inner sidewall of the second concave platform 221 restricts the second lens layer 224 to limit the bending of the second lens layer 224 and maintains pressure on the second lens layer 224.

[0081] The specific steps are as follows:

[0082] Step S121: The first moving part and the third moving part move synchronously, the first moving part controls the movement of the first concave platform 211, and the third moving part controls the movement of the first adsorption member 213; or, the second moving part and the fourth moving part move synchronously, the second moving part controls the movement of the second concave platform 221, and the fourth moving part controls the movement of the second adsorption member 223.

[0083] In the embodiments of this application, before the first lens layer 214 and the second lens layer 224 are connected, the first moving member and the third moving member move synchronously. The first moving member controls the movement of the first concave platform 211, and the third moving member controls the movement of the first adsorption member 213, so that the first concave platform 211 and the first adsorption member 213 move synchronously, thereby ensuring the movement state of the first lens layer 214 and avoiding the bending and deformation of the first lens layer 214 in the movement state, thereby ensuring that the first lens layer 214 bends and deforms after being pressed.

[0084] The second moving member moves synchronously with the fourth moving member. The second moving member controls the movement of the second concave platform 221, and the fourth moving member controls the movement of the second adsorption member 223, so that the second concave platform 221 and the second adsorption member 223 move synchronously, thereby ensuring the movement state of the second lens layer 224 and preventing the second lens layer 224 from bending and deforming in the moving state, thus ensuring that the second lens layer 224 bends and deforms after being pressed.

[0085] Step S122: The distance between the first concave platform 211 and the second concave platform 221 gradually decreases.

[0086] In step S123, the first lens layer 214 and the second lens layer 224 shrink as the distance between the first concave platform 211 and the second concave platform 221 decreases, and the first lens layer 214 and the second lens layer 224 are connected by adhesive 230. At this time, the connection between the first lens layer 214 and the second lens layer 224 is within the space enclosed by the first concave platform 211 and the second concave platform 221.

[0087] In this embodiment, the distance between the first concave platform 211 and the second concave platform 221 gradually decreases, so that the first lens layer 214 and the second lens layer 224 shrink as the distance between them decreases, until the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230. At this time, the connection between the first lens layer 214 and the second lens layer 224 is within the space enclosed by the first concave platform 211 and the second concave platform 221, and the first lens layer 214 and the second lens layer 224 bend and deform within this space, so that the first lens layer 214 and the second lens layer 224 can bend and deform independently within the sealed space, avoiding the influence of the external environment, thereby realizing the bending and deformation of the first lens layer 214 and the second lens layer 224 in an independent space.

[0088] Step S124: The first lens layer 214 is located in the first groove of the first concave platform 211; the inner sidewall of the first concave platform 211 is outside the outer sidewall of the first lens layer 214 and can contact the outer sidewall of the first lens layer 214 to restrict the outer sidewall of the first lens layer 214.

[0089] In the embodiments of this application, the first lens layer 214 is located in the first groove of the first concave platform 211, and the inner sidewall of the first groove formed in the first concave platform 211 is outside the outer sidewall of the first lens layer 214, so that the first lens layer 214 can contact the inner sidewall of the first groove formed in the first concave platform 211 after being compressed, thereby restricting the outer sidewall of the first lens layer 214 and maintaining the bending state of the first lens layer 214.

[0090] In step S125, the second lens layer 224 is located in the second groove of the second concave platform 221; the inner sidewall of the second concave platform 221 is outside the outer sidewall of the second lens layer 224 and can contact the outer sidewall of the second lens layer 224 to restrict the outer sidewall of the second lens layer 224.

[0091] In the embodiments of this application, the second lens layer 224 is located in the second groove of the second concave platform 221, and the inner sidewall of the second groove formed in the second concave platform 221 is outside the outer sidewall of the second lens layer 224, so that the second lens layer 224 can contact the inner sidewall of the second groove formed in the second concave platform 221 after being compressed, thereby restricting the outer sidewall of the second lens layer 224 and maintaining the bending state of the second lens layer 224.

[0092] refer to Figure 4 In step S130, when the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230, the first adsorption member 213 stops moving and adsorbs the first lens layer 214, the first concave platform 211 continues to move and bends and deforms the first lens layer 214, and restricts the bending and deformation of the first lens layer 214; the second adsorption member 223 stops moving and adsorbs the second lens layer 224, the second concave platform 221 continues to move and bends and deforms the second lens layer 224, and restricts the bending and deformation of the second lens layer 224.

[0093] In the embodiments of this application, when the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230, the first adsorption member 213 stops moving and adsorbs the first lens layer 214, while the first concave platform 211 continues to move and bends the first lens layer 214. At this time, the first lens layer 214 is bent and deformed by the opposing forces of the first adsorption member 213 and the first concave platform 211, and the first concave platform 211 restricts the bending deformation of the first lens layer 214, thus ensuring the bending accuracy of the first lens layer 214 and limiting the rebound of the first lens layer 214.

[0094] The second adsorption member 223 stops moving and adsorbs the second lens layer 224. The second concave platform 221 continues to move and bends the second lens layer 224. At this time, the second lens layer 224 is bent and deformed by the opposing forces of the second adsorption member 223 and the second concave platform 221. The second concave platform 221 restricts the bending deformation of the second lens layer 224, ensuring the bending accuracy of the second lens layer 224 and limiting the rebound of the second lens layer 224.

[0095] The specific steps are as follows:

[0096] In step S131, when the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230, both sides of the adhesive 230 are connected to the first lens layer 214 and the second lens layer 224, and there is still a gap between the first concave platform 211 and the second concave platform 221.

[0097] In the embodiments of this application, when the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230, both sides of the adhesive 230 are connected to the first lens layer 214 and the second lens layer 224 so that the first lens layer 214 and the second lens layer 224 are in a connected state, and there is also a gap between the first concave platform 211 and the second concave platform 221 so that the first concave platform 211 and the second concave platform 221 can be further bonded.

[0098] Step S132: The first adsorption member 213 stops moving and adsorbs the first lens layer 214. At this time, the first lens layer 214 is subjected to the adsorption force of the first adsorption member 213.

[0099] Step S133: The first concave platform 211 continues to move and applies pressure to the first lens layer 214, causing the first lens layer 214 to bend and deform under pressure. At this time, the sidewall of the groove formed in the first concave platform 211 restricts the bending and deformation of the first lens layer 214.

[0100] In the embodiments of this application, the first adsorption member 213 stops moving and adsorbs the first lens layer 214, so that the third region 2142 of the first lens layer 214 is subjected to an adsorption force. At this time, the first lens layer 214 is subjected to the adsorption force of the first adsorption member 213. In addition, the first concave platform 211 continues to move and applies pressure to the first lens layer 214, so that the first region 2141 of the first lens layer 214 is subjected to the pressure of the first concave platform 211. The first lens layer 214 bends and deforms under pressure. At this time, the sidewall of the groove formed in the first concave platform 211 restricts the bending deformation of the first lens layer 214 and ensures the bending accuracy and springback limitation of the first lens layer 214.

[0101] In step S134, the second adsorption member 223 stops moving and adsorbs the second lens layer 224. At this time, the second lens layer 224 is subjected to the adsorption force of the second adsorption member 223.

[0102] In step S135, the second concave platform 221 continues to move and applies pressure to the second lens layer 224, causing the second lens layer 224 to bend and deform under pressure. At this time, the sidewalls of the groove formed in the second concave platform 221 restrict the bending and deformation of the second lens layer 224.

[0103] In the embodiments of this application, the second adsorption member 223 stops moving and adsorbs the second lens layer 224, so that the fourth region 2242 of the second lens layer 224 is subjected to an adsorption force. At this time, the second lens layer 224 is subjected to the adsorption force of the second adsorption member 223. In addition, the second concave platform 221 continues to move and applies pressure to the second lens layer 224, so that the second region 2241 of the second lens layer 224 is subjected to the pressure of the second concave platform 221. The second lens layer 224 bends and deforms under pressure. At this time, the sidewall of the groove formed in the second concave platform 221 restricts the bending deformation of the second lens layer 224 and ensures the bending accuracy and springback limitation of the second lens layer 224.

[0104] In step S136, the second concave platform 221 and the first concave platform 211 continue to move.

[0105] Step S137: When the second concave platform 221 and the first concave platform 211 are in contact with each other, the space between the second concave platform 221 and the first concave platform 211 is enclosed and covers the first lens layer 214 and the second lens layer 224.

[0106] In step S138, the first lens layer 214 and the second lens layer 224 are subjected to pressure from the second concave platform 221 and the first concave platform 211 within the space, so as to maintain the bending state of the second concave platform 221 and the bending state of the first concave platform 211.

[0107] In the embodiments of this application, the second concave platform 221 and the first concave platform 211 continue to move so that the second concave platform 221 and the first concave platform 211 fit together and enclose a space between the second concave platform 221 and the first concave platform 211, covering the first lens layer 214 and the second lens layer 224, thereby facilitating the bending and pressure holding of the first lens layer 214 and the second lens layer 224 within the space. At this time, the first lens layer 214 and the second lens layer 224 are subjected to the pressure holding of the second concave platform 221 and the first concave platform 211 within the space, so as to maintain the bending state of the second concave platform 221 and the bending state of the first concave platform 211.

[0108] In the embodiments of this application, when the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230, the states of the third and fourth moving members are adjusted from a moving state to a stationary state, thereby ensuring that the first adsorption member 213 and the second adsorption member 223 are stationary, while the first and second moving members are still in a moving state. At this time, the second and fourth moving members are adjusted from synchronous movement to asynchronous movement to control the force exerted by the second patch platform and the second adsorption member on the second lens layer 224. The second patch platform and the second adsorption member 223 bend and deform the second lens layer 224. Optionally, the first, second, third, and fourth moving members are all moving arms or lifting arms.

[0109] Furthermore, both the first adsorption member 213 and the second adsorption member 223 stop moving, while the first concave platform 211 and the second concave platform 221 continue to move, causing the first lens layer 214 and the second lens layer 224 to be subjected to two opposing forces; based on these two opposing forces, the first lens layer 214 and the second lens layer 224 are bent and deformed. At this time, the third region 2142 of the first lens layer 214 is subjected to an upward elastic pressure, and the first region 2141 of the first lens layer 214 is subjected to a downward pressure; the fourth region 2242 of the second lens layer 224 is subjected to a downward elastic pressure, and the second region 2241 of the second lens layer 224 is subjected to an upward pressure.

[0110] The method for attaching the concave platform frame of the lens further includes: comparing the air gap between the first lens layer 214 and the second lens layer 224 with a preset air gap; if the air gap between the first lens layer 214 and the second lens layer 224 is greater than the preset air gap, then the movement of the first concave platform 211 and / or the second concave platform 221 is stopped, and the curvature of the first lens layer 214 and the second lens layer 224 is maintained.

[0111] The air gap between the first lens layer 214 and the second lens layer 224 is compared with a preset air gap; if the air gap between the first lens layer 214 and the second lens layer 224 is greater than the preset air gap, the movement of the first concave platform 211 and / or the second concave platform 221 is stopped, and the curvature of the first lens layer 214 and the second lens layer 224 is maintained.

[0112] In the embodiments of this application, the air gap c between the first lens layer 214 and the second lens layer 224 is compared with a preset air gap d, and the difference between the air gap c between the first lens layer 214 and the second lens layer 224 and the preset air gap d is calculated so as to evaluate the difference between the air gap c between the first lens layer 214 and the second lens layer 224 and the preset air gap d.

[0113] In the embodiments of this application, when the air gap c between the first lens layer 214 and the second lens layer 224 is greater than the preset air gap d, the first lens layer 214 and the second lens layer 224 meet the requirements after being compressed, thereby the lens meets the usage requirements and improves the display effect of the lens.

[0114] At this point, the degree of curvature of the first lens layer 214 should be related to the curvature height. Assuming the curvature height is 'a', which can be measured by a curvature measuring device, and the length of the horizontal reference plane is 'b', the curvature radius of the first lens layer 214 can be calculated as follows:

[0115]

[0116] According to the above formula, by selecting appropriate bonding pressure, Young's modulus of the bonding wafer, and other parameters, the bending height of the first lens layer 214 can be further adjusted. This allows for adjustment of the bonding pressure or bonding parameters, thereby adjusting the bending height of the first lens layer 214. This improves the display effect while preventing excessive bending deformation of the first and second lens layers 224, thus avoiding any impact on their display performance. Similarly, the degree of bending of the first lens layer 214 should be related to the bending height and is subject to the above formula.

[0117] Alternatively, the air gap between the first lens layer 214 and the second lens layer 224 can be measured using a measuring device, which can be a measuring device for measuring air gaps.

The adhesive 230 is disposed on one side of the first lens layer 214 of the first concave component 210 and the second lens layer 224 of the second concave component 220, and is capable of connecting the first lens layer 214 and the second lens layer 224.

[0119] The first concave component 210 includes a first concave platform 211, a first elastic pad 212, a first adsorption member 213, and a first lens layer 214. The first concave platform 211 houses the first elastic pad 212, the first adsorption member 213, and the first lens layer 214. The first concave platform 211 and the first adsorption member 213 are respectively connected to a first moving member and a second moving member. The first concave platform 211 is provided with a first channel 215 through which the first adsorption member 213 passes.

[0120] The second concave component 220 is disposed on one side of the first concave component 210, and the height between the second concave component 220 and the first concave component 210 is adjustable. The second concave component 220 includes a second concave platform 221, a second elastic pad 222, a second suction member 223, and a second lens layer 224. The second concave platform 221 houses the second elastic pad 222, the second suction member 223, and the second lens layer 224. The second concave platform 221 and the second suction member 223 are respectively connected to a third moving member and a fourth moving member. Optionally, the first lens layer 214 and the second lens layer 224 are connected in multiple layers to improve the lens effect. The second concave platform 221 is provided with a second channel 225 through which the second suction member 223 passes.

[0121] In some embodiments of this application, when the first lens layer 214 and the second lens layer 224 are connected by adhesive 230, the first lens layer 214 is acted upon by the first concave platform 211 and the first suction member 213, with the first lens layer 214 embedded within the first concave platform 211 and the inner wall of the first concave platform 211 restricting the first lens layer 214; similarly, the second lens layer 224 is acted upon by the second concave platform 221 and the second suction member 223, with the second lens layer 224 embedded within the second concave platform 221 and the inner wall of the second concave platform 221 restricting the second lens layer 224. When the first adsorption member 213 stops moving and adsorbs the first lens layer 214, the first concave platform 211 continues to move and bends the first lens layer 214, while limiting the bending deformation of the first lens layer 214 to ensure the bending accuracy and springback limitation of the first lens layer 214. The second adsorption member 223 stops moving and adsorbs the second lens layer 224, the second concave platform 221 continues to move and bends the second lens layer 224, while limiting the bending deformation of the second lens layer 224 to ensure the bending accuracy and springback limitation of the second lens layer 224.
