Description

Technical Field

[0001] The present invention belongs to the technical field of electronic equipment, and in particular relates to a camera lens and a preparation method thereof, and electronic equipment. Background Art

[0002] The camera lens can protect and shield the internal components, and also has a decorative effect. However, the current camera lens has a single function, so it is necessary to improve the camera lens. Summary of the invention

[0003] The present invention is made based on the findings and recognition of the following facts and problems by the inventors.

[0004] The inventor found that in electronic devices, camera lenses are mainly main camera, wide-angle, telephoto lenses, etc., and there is no need for special functions except for the need for the window area to be completely hollowed out and transparent. Currently, decoration is generally performed in the non-window area of ​​the lens, but the current decorative effect is single.

[0005] The inventor has found that when the lens of an electronic device has a microscope function, it is necessary to provide fill light to the lens, but there is currently no report on a camera lens with a fill light function.

[0006] In order to improve the above technical problems, the present invention provides a camera lens, the camera lens includes a substrate, the substrate includes a window area and a non-window area surrounding the window area, the non-window area of ​​the substrate is provided with a first shielding part and a second shielding part, the first shielding part includes a first shielding sub-part and a second shielding sub-part, the first shielding sub-part and the second shielding sub-part surround the window area, and the second shielding part is located between the first shielding sub-part and the second shielding sub-part; the transmittance of the second shielding part and the substrate under visible light is 27-37%. Thus, through the light transmission of the second shielding part and the substrate, the lens can be supplemented with light to meet the requirements of the microscope for light. If the transmittance of the second shielding part and the substrate is too large, the internal components located below the camera lens cannot be covered, affecting the visual effect. If the transmittance of the second shielding part and the substrate is too small, the supplementary light effect is poor, the clarity of the photos taken is low, and it cannot meet the requirements.

[0007] The present invention also provides a method for preparing a camera lens, the method comprising: providing a substrate, the substrate comprising a window area and a non-window area surrounding the window area, the non-window area of ​​the substrate being provided with a first shielding portion and a second shielding portion, the first shielding portion comprising a first shielding sub-portion and a second shielding sub-portion, the first shielding sub-portion and the second shielding sub-portion surrounding the window area, the second shielding portion being located between the first shielding sub-portion and the second shielding sub-portion; the transmittance of the second shielding portion and the substrate under visible light is 27-37%. Thus, a camera lens with a semi-transparent function can be prepared by this method, which improves the defect of the current camera lens having a single function.

[0008] The present invention also provides an electronic device, the electronic device comprising the camera lens described above. Thus, the camera lens has a semi-transparent effect, and the camera lens of the present invention is used in conjunction with a lens having a microscope function, and the camera lens of the present invention can fill in the lens with light, making the photographed object clearer, and further having a better microscope effect.

DETAILED DESCRIPTION

[0030] The embodiments of the present application are described in detail below. The embodiments described below are exemplary and are only used to explain the present application, and should not be construed as limiting the present application. If no specific technology or conditions are indicated in the embodiments, the technology or conditions described in the documents in this area or the product instructions are used. The reagents used are not indicated by the manufacturer, and are all conventional products that can be purchased from the market.

[0031] The existing camera lenses have single functions and single appearance effects, and the decorative effect is poor.

[0032] In order to improve the above technical problems, the present invention provides a camera lens, referring to Figure 1 The camera lens 100 includes a substrate, the substrate includes a window area A and a non-window area B surrounding the window area A, the non-window area B of the substrate is provided with a first shielding portion and a second shielding portion D, the first shielding portion includes a first shielding sub-portion C and a second shielding sub-portion E, the first shielding sub-portion C and the second shielding sub-portion E surround the window area A, the second shielding portion D is located between the first shielding sub-portion C and the second shielding sub-portion E, and the transmittance of the second shielding portion and the substrate under visible light is 27-37%. Therefore, the camera lens of the present invention has a local semi-transparent effect, which can achieve a fill light effect during microscopic imaging, ensuring that the microscopic imaging is delicate and clear. Compared with traditional camera lenses, the design of the present invention has a fill light function. In addition, the camera lens of the present invention can also hide the structure under the camera lens. In addition, the camera lens of the present application presents different visual effects when the lights are off and when the lights are on, and has a gorgeous appearance effect. Due to the difference in appearance between the camera lens of the present invention and the traditional camera lens, the user experience can be improved, and the market competitiveness of the product can be further improved.

[0033] It should be noted that the second shielding portion is arranged on the substrate, and the transmittance of the second shielding portion and the substrate in visible light is 27-37%, which means that at the position where the second shielding portion is located, there are stacked substrates and second shielding portions, and the transmittance of the lens at this position in visible light is 27-37%.

[0034] For ease of understanding, the following is a brief explanation of the principle by which the camera lens can achieve the above functions:

[0035] With the improvement of the requirements for camera functions of current electronic devices, camera modules with single effects can no longer meet the needs. For example, most current electronic devices are equipped with camera modules with macro, telephoto or wide-angle effects. However, the current camera modules still do not have microscope functions. Therefore, if the microscopic function can be realized, the functions and application scope of electronic devices will be further improved. The camera lens proposed in this application can be matched with the lens with microscopic function in the camera module and the fill light component to realize the shooting of microscopic photos. Specifically, the first shielding sub-part and the second shielding sub-part of the camera lens can shield the components under the camera lens. The second shielding part and the substrate can fill the light of the lens when the fill light component emits light due to the high transmittance, thereby further improving the effect of the microscope and making the photos taken clearer. Furthermore, the fill light component can include a light guide column and a light source. When the microscope function needs to be used, the light source is turned on to emit light. The light emitted by the light source can pass through the light guide column, and then through the second shielding part and the substrate on the camera lens, and irradiate the photographed object to fill the light of the lens.

[0036] The shape of the camera lens includes but is not limited to a circle, an ellipse, a square, a rectangle, a polygon or an irregular shape. It should be noted that the shape of the camera lens in the drawings of the present invention is only for illustrative purposes and should not be construed as a limitation to the present invention. In other words, the shape of the camera lens may also be other shapes mentioned above. The present invention does not limit the size of the camera lens, and technicians can choose according to the needs of use.

[0037] According to an embodiment of the present invention, the substrate is sapphire or glass, and the thickness of the substrate is 0.4-1 mm, for example, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm. If the thickness of the substrate is too small, the strength of the substrate will be too small, and there is a problem of easy cracking. If the thickness of the substrate is too large, it will be difficult to produce, and the excessive thickness will further increase the thickness and quality of the electronic device, which does not meet the development trend of thin and light electronic devices. In addition, the excessive thickness will increase the production cost.

[0038] The substrate has a transmittance of 85-87% under visible light. Thus, the substrate can cooperate with the second shielding portion so that the transmittance of the second shielding portion and the substrate meets the requirements of the microscope. In addition, sufficient light can pass through the window area A of the camera lens, so that the lens located below the camera lens can shoot objects more clearly.

[0039] According to an embodiment of the present invention, the wavelength of visible light is 380-780 nm.

[0040] According to an embodiment of the present invention, a non-window region of the substrate is provided with a first shielding sub-portion and a second shielding sub-portion, and the first shielding sub-portion and the second shielding sub-portion include a light shielding layer. Figure 2 A cross-sectional view of a camera lens in one embodiment of the present invention is shown, referring to Figure 2 , a light shielding layer 120 is disposed on the substrate 110. Furthermore, the material forming the light shielding layer 120 is black ink. Therefore, by disposing the light shielding layer 120 in the area where no light transmittance requirement is required, the internal components located under the camera lens can be better shielded. In addition, the positions corresponding to the first shielding sub-portion and the second shielding sub-portion have different visual effects from the window area, which has a better visual impact effect.

[0041] Furthermore, the thickness of the light-shielding layer is 5-6 μm, at which thickness, the internal components under the lens can be better shielded, thus achieving a better appearance effect.

[0042] According to an embodiment of the present invention, the second shielding portion D includes a texture layer 130, an optical coating layer 140 and a semi-transparent ink layer 150 stacked in sequence. Figure 3 The second shielding portion D is disposed on the substrate 110, and the texture layer 130 is disposed on a side close to the substrate 110. Thus, the substrate 110 cooperates with the texture layer 130, the optical coating layer 140 and the semi-transparent ink layer 150 to make the transmittance of the second shielding portion and the substrate under visible light 27-37%, which meets the light requirements of the microscope.

[0043] refer to Figure 4 The light shielding layer 120 and the second shielding portion D (the texture layer 130 , the optical coating layer 140 and the semi-transparent ink layer 150 ) are arranged on the same side of the substrate 110 .

[0044] According to an embodiment of the present invention, the surface of the texture layer 130 away from the substrate 110 has a plurality of stripes, and the spacing between adjacent stripes is 0.03-0.07 mm, such as 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm or 0.07 mm. In the texture layer, the line width of the stripes is 0.03-0.07 mm, such as 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm or 0.07 mm. Therefore, if the spacing between adjacent stripes and the line width of the stripes are too small, it is not easy to see the physical effect of the stripes. If the spacing between adjacent stripes and the line width of the stripes are too large, the fineness will be poor. When the spacing between adjacent stripes is 0.03-0.07 mm and the line width of the stripes is 0.03-0.07 mm, the camera lens has a higher fineness and a better appearance.

[0045] Furthermore, the texture layer 130 has a transmittance of 94-98% under visible light. Thus, the texture layer 130 can cooperate with other layered structures of the second shielding part and the substrate 110 to make the transmittance of the second shielding part and the substrate meet the requirements of the microscope.

[0046] Furthermore, the texture layer has a thickness of 9-11 μm, at which thickness, a better appearance effect can be achieved.

[0047] According to an embodiment of the present invention, the material forming the optical coating layer 140 is SiO 2 、TiO 2 and Pb 2 O 5 At least one of. Further, the thickness of the optical coating layer 140 is 260-290nm, for example, 260nm, 265nm, 270nm, 275nm, 280nm, 285nm or 290nm. The present invention does not limit the number of layers of the optical coating layer. Specifically, the number of layers of the optical coating layer can be 1 layer, 2 layers, 3 layers, 4 layers, 5 layers, 6 layers, 7 layers or more layers. When the number of layers of the optical coating layer is more than 2 layers, the optical coating layer includes a plurality of optical coating sub-layers, wherein the thickness of each optical coating sub-layer can be the same or different, as long as the sum of the thickness of each optical coating sub-layer is 260-290nm.

[0048] Furthermore, the transmittance of the optical coating layer under visible light is 45-61%. Thus, the optical coating layer can cooperate with other layered structures of the second shielding part and the substrate, so that the transmittance of the second shielding part and the substrate meets the requirements of the microscope.

[0049] According to an embodiment of the present invention, the material forming the semi-permeable ink layer 150 is gray-phase ink, thereby making the color of the photographed photo close to the color of the real object, and having the advantage of small hue deviation.

[0050] Furthermore, the thickness of the semi-permeable ink layer 150 is 5-8 μm, at which thickness, the photographed photo can have a better effect.

[0051] Furthermore, the transmittance of the semi-transparent ink layer under visible light is 53-63%. Therefore, the semi-transparent ink layer can cooperate with other layered structures of the second shielding part D and the substrate, so that the transmittance of the second shielding part and the substrate meets the requirements of the microscope.

[0052] It should be noted that Figure 4 and Figure 7The positions of the various layered structures on the substrate are only exemplified, and the thickness of the various layered structures in the accompanying drawings should not be understood as limiting the present application. Specifically, as mentioned above, the thickness of the shading layer 120 is 5-6μm, the thickness of the texture layer 130 is 9-11μm, the thickness of the optical coating layer 140 is 260-290nm, and the thickness of the semi-permeable ink layer 150 is 5-8μm. At this time, the camera lens can have a better effect. Although the surface on one side of the substrate is not uniformly thick at this time, the thickness of the layered structure located on the substrate is very small compared to the thickness of other components of the electronic device. When assembling the electronic device, the uneven thickness at different positions of the lens has almost no effect on other components and can still meet the assembly requirements.

[0053] The present invention arranges a texture layer 130, an optical coating layer 140 and a semi-transparent ink layer 150 on the substrate 110, which can achieve effects such as microscope fill light, mechanism hiding, uniform light guidance, and gorgeous appearance, thereby greatly improving the expressiveness of the camera lens 100, making the appearance more layered and more gorgeous, and can present different functional requirements and appearance effects in different scenes, bringing a new experience to users, increasing user stickiness, and further improving the expressiveness of the product.

[0054] According to an embodiment of the present invention, the camera lens 100 further includes an anti-fingerprint film layer 160 .

[0055] The substrate 110 has a first surface 110a and a second surface 110b opposite to each other. Figure 5 , Figure 6 and Figure 7 , the light shielding layer 120 and the texture layer 130, the optical coating layer 140 and the semi-permeable ink layer 150 (i.e., the second shielding portion) are arranged on the first surface 110a of the substrate 110. The anti-fingerprint film layer 160 is arranged on the second surface 110b. The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In other words, the light shielding layer 120 and the texture layer 130, the optical coating layer 140 and the semi-permeable ink layer 150 can also be arranged on the second surface 110b of the substrate 110, and the anti-fingerprint film layer 160 can also be arranged on the first surface 110a of the substrate 110. That is, the anti-fingerprint film layer 160 and the light shielding layer 120, the texture layer 130, the optical coating layer 140 and the semi-permeable ink layer 150 are not on the same side of the substrate 110.

[0056] Furthermore, the anti-fingerprint film layer 160 covers the substrate 110, that is, the anti-fingerprint film layer 160 covers the window area A and the non-window area B. Thus, the camera lens can have the advantages of anti-fingerprint, anti-oil, anti-dust and the like.

[0057] Furthermore, in the electronic device, the anti-fingerprint film layer 160 on the camera lens is located on the outside of the electronic device, which can prevent oil stains, fingerprints, etc. from affecting the shooting effect of the camera lens. The light shielding layer 120 and the texture layer 130, the optical coating layer 140 and the semi-transparent ink layer 150 are located on the inside of the electronic device. Specifically, refer to Figure 1 The second shielding part is arranged in the non-window area of ​​the substrate. The second shielding part includes a texture layer 130, an optical coating layer 140 and a semi-transparent ink layer 150 stacked in sequence. The position corresponding to the second shielding part constitutes a semi-transparent area. The substrate and the second shielding part (texture layer 130, optical coating layer 140 and semi-transparent ink layer 150) cooperate with each other, so that the lens at the semi-transparent area (the lens structure at this position is a stacked substrate and a second shielding part) has a transmittance of 27-37% under visible light. Sufficient light can pass through the lens at the semi-transparent area to fill in the camera lens and meet the light requirements of the microscope. Located on both sides of the second shielding part D are the first shielding sub-part C and the second shielding sub-part E. The first shielding sub-part and the second shielding sub-part include a light shielding layer. This design can make the lens at the position of the first shielding sub-part C and the second shielding sub-part E have a shielding function, and can effectively shield the internal components located below this position. In addition, since the second shielding portion D has a different layered structure from the first shielding sub-portion C and the second shielding sub-portion E, the lens in the non-window area B has a different appearance effect, thereby improving the user's visual experience.

[0058] refer to Figure 8 and Fig. 9 The camera lens of the present invention has different appearance effects in the light-off state and the light-on state. In the light-on state, the position corresponding to the second shielding part of the camera lens can be evenly illuminated, which can not only fill in the light for the lens, but also has a gorgeous appearance effect. The light-off state is the state when the light source of the fill-in light component is turned off, and the light-on state is the state when the light source of the fill-in light component is turned on.

[0059] The present invention also provides a method for preparing a camera lens, wherein the camera lens comprises a substrate, and the method comprises:

[0060] S100, provide substrate

[0061] In this step, a substrate is provided. The substrate is provided with a window area and a non-window area surrounding the window area, the non-window area of ​​the substrate is provided with a first shielding portion and a second shielding portion, the first shielding portion includes a first shielding sub-portion and a second shielding sub-portion, the first shielding sub-portion and the second shielding sub-portion surround the window area, the second shielding portion is located between the first shielding sub-portion and the second shielding sub-portion, and the transmittance of the second shielding portion and the substrate under visible light is 27-37%.

[0062] The present invention does not limit the shapes and specific sizes of the window area, the non-window area, the first shielding sub-portion, the second shielding sub-portion, and the second shielding portion, and technicians can choose according to usage requirements.

[0063] Furthermore, technicians can obtain a substrate of a specified size through processes including but not limited to crystal growth, rod cutting, wire cutting, grinding, and polishing. Furthermore, the substrate can be sapphire or glass, wherein the main component of sapphire is aluminum oxide.

[0064] Furthermore, the thickness of the substrate may be 0.4-1 mm, preferably 0.5 mm.

[0065] The transmittance of the substrate under visible light is 85-87%, which can ensure that sufficient light can pass through the window area, and the substrate can cooperate with other structures to make the transmittance of the second shielding part and the substrate meet the requirements of the microscope. Fig.10 , the method may further include:

[0066] S200: Forming a first shielding sub-portion and a second shielding sub-portion

[0067] In this step, a first shielding sub-portion and a second shielding sub-portion are formed. Specifically, the first shielding sub-portion and the second shielding sub-portion are formed on the same side of the substrate. Fig.11 Through this step, a hollow window area can be formed, and a hollow area can be formed between the first shielding sub-section and the second shielding sub-section, which is conducive to accurately forming a layered structure such as a texture layer at a position between the first shielding sub-section and the second shielding sub-section. Specifically, the window area is located inside the first shielding sub-section.

[0068] Furthermore, the shading layer can be formed by a silk screen printing process, wherein the screen mesh number of the silk screen printing can be 450-550 mesh. If the screen mesh number is too low, jagged edges are easily formed at the edge of the shading layer, affecting the visual effect. If the screen mesh number is too high, the bottom is easily visible, which easily exposes the defects of the subsequent process. Under the condition of 450-550 mesh, the edge of the shading layer is regular, avoiding the problem of burrs on the window. Further, the screen mesh number of the silk screen printing is preferably 500 mesh.

[0069] According to an embodiment of the present invention, referring to Fig.12 , the method may further include:

[0070] S300: Forming a second shielding portion

[0071] In this step, a second shielding part is formed. The second shielding part includes a texture layer, an optical coating layer and a semi-transparent ink layer stacked in sequence, and the texture layer is arranged on the side close to the substrate. Thus, the substrate and the second shielding part (texture layer, optical coating layer and semi-transparent ink layer) arranged on the substrate cooperate with each other, so that the transmittance of the second shielding part and the substrate can meet the requirements of the microscope.

[0072] refer to Fig.13 , step S300 further includes:

[0073] S310, forming a texture layer on the substrate located between the first shielding sub-portion and the second shielding sub-portion

[0074] In this step, a texture layer is formed on the substrate located between the first shielding sub-section and the second shielding sub-section. Specifically, glue is first applied to the substrate at this position, and a texture mold is covered and roller pressed, and the texture of the mold is transferred to the middle position of the first shielding sub-section and the second shielding sub-section of the camera lens through GDM (Glass Direct UV Molding), and the texture overlaps the light shielding layer.

[0075] Furthermore, the overlap width can be about 0.3 mm to ensure that the texture layer is accurately positioned without deviation. It should be noted that the overlap width can be adaptively adjusted according to the size of the camera lens and the size of each area.

[0076] In the texture layer, the spacing between adjacent stripes is 0.03-0.07 mm, and the line width of the stripes is 0.03-0.07 mm, thereby ensuring that the texture layer has a more refined appearance. For example, the spacing between adjacent stripes can be 0.05 mm, and the line width of the stripes can be 0.05 mm.

[0077] Furthermore, the transmittance of the texture layer under visible light is 94-98%. Therefore, the texture layer can cooperate with other layered structures of the second shielding part and the substrate to make the transmittance of the second shielding part and the substrate meet the requirements.

[0078] S320, forming an optical coating layer on a side of the texture layer away from the substrate

[0079] The material forming the optical coating layer can be SiO 2 、TiO 2 and Pb 2 O 5 Specifically, the optical coating layer can be SiO 2 / TiO 2 Stacked film system, SiO 2 / Pb 2 O 5 Stacked film system, TiO2 / Pb 2 O 5 The total thickness of the stacked film system can be controlled within a range of 260-290 nm.

[0080] The transmittance of the optical coating layer under visible light is 45-61%. Exemplarily, the optical coating layer may include seven optical coating sub-layers stacked in sequence, and the structure of the optical coating layer is SiO 2 / TiO 2 / SiO 2 / TiO 2 / SiO 2 / TiO 2 / SiO 2 , where the thickness of each optical coating sub-layer is: 30.23nm, 17.83nm, 22.17nm, 36.64nm, 96.73nm, 60.41nm, 10.08nm. The relationship between the transmittance of the optical coating layer and the wavelength is shown in the figure below. Fig.14 Reference Fig.14 The transmittance of the optical coating layer at 550nm is about 58%.

[0081] The transmittance of the optical coating layer under visible light is 45-61%. The optical coating layer cooperates with the substrate, the texture layer, and the semi-transparent ink layer to make the transmittance of the second shielding part and the substrate under visible light meet the requirements of the microscope.

[0082] According to an embodiment of the present invention, when preparing the optical coating layer, the projection of the optical coating layer on the substrate further covers the window area.

[0083] S330, forming a semi-transparent ink layer on the side of the optical coating layer away from the texture layer

[0084] In this step, a semi-transparent ink layer is formed on the side of the optical coating layer away from the texture layer. Fig.15 As shown. Technicians can adjust the ink according to color requirements and transmittance requirements. Exemplarily, the ink can be a gray phase ink, and a semi-permeable ink layer can be formed by a silk screen printing process, wherein the screen mesh number of the silk screen printing can be 400-440 mesh, preferably 420 mesh, and the thickness of the semi-permeable ink layer can be 5-8μm. The overlap width of the gray phase ink and the first shielding sub-section and the second shielding sub-section is about 0.4mm, ensuring that the semi-permeable ink layer can cover the area corresponding to the middle of the first shielding sub-section and the second shielding sub-section. The transmittance of the semi-permeable ink layer prepared in this step under visible light is 53-63%.

[0085] According to an embodiment of the present invention, referring to Fig.16 , the method may further include:

[0086] S400, remove the optical coating layer located in the window area

[0087] In this step, the optical coating layer located in the window area is removed. Specifically, an alkaline stripping solution can be used to strip the optical coating layer in the window area to ensure that the transmittance of the window area meets the light transmittance requirement of the lens, that is, the transmittance of the window area under visible light reaches 85-87%.

[0088] According to an embodiment of the present invention, referring to Fig.17 , the method may further include:

[0089] S500, forming an anti-fingerprint film layer

[0090] In this step, an anti-fingerprint film layer is formed. Further, the anti-fingerprint film layer covers the substrate, thereby making the camera lens have anti-oil, anti-fingerprint and other effects.

[0091] If necessary, the method may further include steps such as inspecting the packaging.

[0092] Through the first shielding sub-section and the second shielding sub-section, each layered structure of the second shielding section located between the first shielding sub-section and the second shielding sub-section can be protected to prevent subsequent processes from causing damage to each layered structure in the second shielding section. For example, when removing the optical coating layer located in the window area, it can prevent the alkaline stripping solution from entering the edge of each layered structure of the second shielding section to damage the layered structure and thus affect the light transmission effect.

[0093] The method can be used to produce a camera lens with a semi-transparent function. The substrate of the present invention cooperates with the texture layer, optical coating layer and semi-transparent ink layer of the second shielding part, so that the transmittance of the second shielding part and the substrate under visible light is 27-37%. Thus, the lens can be supplemented with light, and the camera lens cooperates with the lens with a microscope function to make the photos taken clearer, thereby improving the defect of the current camera lens with a single function.

[0094] The present invention also provides an electronic device, referring to Fig.18 , the electronic device 1000 includes the camera lens described above. Therefore, the electronic device 1000 has all the features and advantages of the camera lens described above, which will not be described in detail here.

[0095] It should be noted that the electronic device may be a mobile phone, and the camera lens of the present application is preferably used for the rear camera lens of the electronic device.

[0096] According to an embodiment of the present invention, the electronic device 1000 further includes a display screen 300, a housing 200, a fill light assembly and a lens, the camera lens is located on the housing 200, the display screen 300 is connected to the housing 200, the display screen 300 and the housing 200 define a storage space, the fill light assembly and the lens are located within the orthographic projection area of ​​the camera lens, and the fill light assembly and the lens are located inside the storage space, and the fill light assembly includes a light source and a light guide column. Thus, the electronic device has all the features and advantages of the camera lens described above, which will not be repeated here. In general, the camera lens of the present invention has a semi-transparent effect, and can fill light for the lens. When a lens with a microscope function is used, the light source can emit light, and the light guide column guides light, and light is transmitted through the second shielding portion and the substrate of the camera lens to fill light for the lens, which can have a better microscope effect.

[0097] refer to Fig.19 The clothes photos taken by the electronic device of the present invention are clear, and the microscopic state of the clothes can be clearly seen. If ordinary camera lenses are used, the photos taken are not clear due to less light on the photographed objects, and the microscopic state cannot be clearly observed, and the microscopic effect is poor.
