Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The technical scheme of the utility model will be further described with reference to the examples and the accompanying drawings.
Referring to fig. 1 to 2a, the present application discloses an electronic glasses film 100, and can be applied to a lens module 200, wherein the lens module 200 includes a lens 201, and the electronic glasses film 100 includes a film body 10 and a protective film 20. The film body 10 is used for being attached to the lens 201, the film body 10 is circular and has a polarization axis L, and the protective film 20 is disposed on at least one surface of the film body 10. The electronic glasses film 100 comprises at least one identification part 30, wherein the identification part 30 is arranged at the edge of the film body 10 and/or protects the edge of the film 20, and an included angle theta is formed between the connection line of the identification part 30 and the center O of the film body 10 and the polarization axis L.
By providing the identification portion 30 at the edge of the film body 10 or the protective film 20, the direction of the polarization axis L of the film 100 can be quickly identified and the direction of the electronic glasses film 100 can be adjusted to meet the assembly requirement of the polarization direction of the film when the electronic glasses film 100 is attached to the lens 201 or when the electronic glasses film 100 and another electronic glasses film 100 are attached to each other. On the one hand, the direction of the polarization axis L can be accurately judged, and the assembly precision of the film is improved; on the other hand, the time for identifying the polarization axis L of the film material is shortened, and the film pasting efficiency is improved.
Wherein θ satisfies 0.ltoreq.θ.ltoreq.180°, for example, θ may be 0 °, 30 °, 60 °, 90 °, 120 °, 180 °, and the like. That is, the line connecting the marking portion 30 and the center O of the film body 10 may be collinear and co-directional with the polarization axis L, form an acute angle, be perpendicular, form an obtuse angle, be collinear and reverse (as shown in fig. 2a, 2b, 2c, 2d, 2e, respectively).
The protective film 20 is detachably disposed on the film body 10. That is, referring to fig. 3a, when the electronic glasses film 100 is applied to the lens module 200, the film body 10 can be directly attached to the lens 201, i.e. the protective film 20 can be removed (e.g. a peeling protective film) during the film attaching process of the lens 201 of the electronic glasses 300, and only the film body 10 remains after the film attaching, so that the identification portion 30 can be disposed on the film body 10, or both the film body 10 and the protective film 20, and thus, after the protective film 20 is removed, the identification portion 30 remains on the film body 10 for facilitating the identification of the direction of the polarization axis L.
In other examples, referring to fig. 3b, when the electronic glasses film 100 is applied to the lens module 200, the protective film 20 may be attached to the lens 201, i.e. the protective film 20 is not removed (e.g. a non-peeling protective film) but remains on the surface of the film body 10, so the identification portion 30 may be disposed only at the edge of the protective film 20, and thus the disposition of the identification portion 30 will not affect the film body 10. Or the marking parts can be arranged on the film material body 10 and the protective film 20 at the same time.
Alternatively, the protective film 20 may be provided on one of the surfaces of the film body 10, or the protective film 20 may be provided on both of the opposite surfaces of the film body 10. The protective film 20 and the film body 10 may be combined with each other by adsorption, electrostatic action, or adhesion by providing an adhesive layer.
In some embodiments, the protective film 20 has the same shape as the film body 10, and the marking portion 30 protrudes from the edge of the film body 10 or the protective film 20 (the outer convex marking portion 33 shown in fig. 4 a), or the edge of the protective film 20 or the film body 10 is provided with a notch, and the notch is formed as the marking portion 30 (shown in fig. 1).
Through setting up mark portion 30 evagination in membrane material body 10 (or protection film 20), perhaps indent in membrane material body 10 (or protection film 20), can discern the direction of electron glasses membrane material 100 polarization axis L, and then be convenient for discern at the pad pasting in-process. When the marking portion 30 is recessed in the film body 10 (or the protective film 20), the film does not need to be additionally provided with other components, and the structure of the electronic glasses film 100 is simplified. When the identification portion 30 protrudes outside the film body 10 (or the protective film 20), the electronic glasses film 100 may be integrally formed, and the identification portion 30 and the film body 10 may be made of the same material, so that the manufacturing of the electronic glasses film 100 may be simplified.
In some examples, referring to fig. 5a, the film body 10 has a light-transmitting region 12, and when the notch is formed as the identification portion 30, the identification portion 30 is located outside the light-transmitting region 12. Since the film body 10 has an optically effective area for deflecting light, that is, the light transmitting area 12, light can be polarized through this area, and the polarization ability of the light by the external eyeglass film 100 is reduced beyond this area. Therefore, when the identification portion 30 is concavely designed relative to the film body 10, the identification portion 30 is disposed outside the light-transmitting region 12, so as to avoid the influence of the design of the identification portion 30 on the light-transmitting region 12, or avoid the problem of light leakage at the notch of the identification portion 30 after assembling the plurality of electronic glasses films 100.
In other examples, referring to fig. 5b, the lens module 200 further includes a fixing frame 202 for disposing the lens 201, and when the identification portion 30 protrudes from the edge of the film body 10 or the protective film 20, the identification portion 30 does not exceed the inner wall of the fixing frame 202. Since the electronic glasses film 100 is used for attaching to the surface of the lens 201, the lens 201 is mounted with the fixing frame 202 to form the lens module 200. Therefore, the protruding mark portion 30 does not exceed the inner wall of the fixing frame 202, so that the contact between the two can be avoided, and the problem that the electronic glasses film 100 is not firmly adhered to the surface of the lens 201 and is separated due to the scratch of the electronic glasses film 100 and the fixing frame 202 can be prevented.
In some embodiments, referring back to fig. 4a and 4b, the shape of the label 30 includes a circular shape (as shown in fig. 4 a), a polygonal shape (as shown in fig. 4b as triangular label 32). The shape of the marking portion 30 is a projection of the marking portion 30 on a plane perpendicular to the optical axis, as seen in the optical axis direction of the lens 201. By providing the identification portion 30 with a variety of shapes, including but not limited to circular (circular arc), polygonal (e.g., triangular, rectangular, trapezoidal, etc.), it is helpful to distinguish between different types of electronic eyewear film 100 using different shapes.
Referring to fig. 6a and 6b, in some examples, the two identification portions 30 include two, the two identification portions 30 are both disposed on the film material body 10 or the protective film 20, and the two identification portions 30 are symmetrical with respect to a center O of the film material body 10 (as shown in fig. 6 a). Or in other examples, the connection line of the two identification parts 30 does not intersect with the center O of the film material body 10 (as shown in fig. 6 b).
Through setting up two identification parts 30, can utilize two identification parts 30 to form the line simultaneously to utilize the direction that sets up this line to form the contained angle with the direction of polarization axis L, thereby be convenient for discern polarization axis L's direction, further improve the precision of pad pasting.
In some embodiments, referring to fig. 6c, the two markers 30 are shaped differently. For example, one of the indicia 30 is a concave configuration and the other indicia 30 is a convex configuration; or one of the indicia 30 may be circular in shape (e.g., circular indicia 31) and the other indicia 30 may be polygonal in shape (e.g., polygonal indicia 32). In this way, the same electronic glasses film 100 is provided with the identification parts 30 with different shapes, the identification direction with the determined pointing direction can be formed between the two identification parts 30, the direction of the polarization axis L can be conveniently distinguished, and the film pasting precision is further improved.
In some embodiments, the identification parts 30 comprise three (as shown in fig. 6 d), wherein two identification parts 30 are symmetrical with respect to the center O of the film body 10, and the third identification part 30 is located on the symmetry axis of the two identification parts 30. By providing 3 identification parts 30, the alignment points between the electronic glasses film material 100 and the lenses 201 or between the electronic glasses film material 100 and the electronic glasses film material 100 can be increased, and the alignment accuracy can be further improved, so that the film pasting accuracy can be improved.
In some embodiments, the line connecting two marks 30 symmetrical with respect to the center O of the film body 10 is parallel to the polarization axis L. By arranging the connecting line of the two identification parts 30 parallel to the direction of the polarization axis L, the positioning of the polarization axis L direction can be facilitated, so that the time required for alignment of the film is shortened, and the film pasting efficiency is improved.
In a second aspect, referring to fig. 7, the present application further discloses a lens module 200, which includes a lens 201, a fixing frame 202, and the electronic glasses film 100 according to the first aspect, wherein the electronic glasses film 100 is attached to the lens 201, and the fixing frame 202 is sleeved on the periphery of the lens 201.
