The first lens 3421 includes an effective portion 3421a and an inactive portion 3421b provided at an edge of the effective portion 3421 a. The non-effective portion 3421b may be provided only at least a portion of the edge of the effective portion 3421a, or may be provided around the edge of the effective portion 3421a, and the first lens 3421 shown in fig. 9 is provided around the edge of the effective portion 3421a with the non-effective portion 3421b. The "effective portion 3421a of the first lens 3421" refers to an effective portion 3421a of the first lens 3421 for optical imaging in photographing of the camera module 30, and the "non-effective portion 3421b of the first lens 3421" refers to a portion of the first lens 3421 where light entering the non-effective portion 3421b in photographing of the camera module 30 affects the optical imaging effect.

Specifically, the effective portion 3421a of the first lens 3421 is located at the central region of the first lens 3421 to facilitate the light of the photographed object to pass through.

Referring to fig. 11, fig. 11 is a schematic diagram illustrating a structure of a lens according to some embodiments of the present disclosure when light enters the lens during photographing. In the photographing of the camera module 30, light reflected by a subject enters through the lens barrel 341, and sequentially passes through the stacked optical lenses. When light outside the lens enters the inside of the lens, a part of the light passes through the effective portion 3421a of the first lens 3421 and a part of the light passes through the ineffective portion 3421b of the first lens 3421 according to an incident angle when the light enters the lens. The light passing through the effective portion 3421a can be used for effective optical imaging of the camera module 30, the light passing through the non-effective portion 3421b can generate reflection and scattering phenomena at the non-effective portion 3421b, and the reflected and scattered stray light finally reaches the photosensitive chip 31 of the camera module 30, so that the optical imaging effect of the camera module 30 can be affected, and the use experience of a user is reduced.

In fig. 11, the incident angle of the light is about 10 degrees, and when the incident angle of the light is greater than 0 degrees, less than or equal to 70 degrees, and greater than or equal to 130 degrees, and less than 180 degrees, the incident angle of the light may generate stray light, which further affects the imaging effect of the camera module 30.

In order to solve the above-mentioned problem and improve the shooting effect of the camera module 30, the present application further provides a lens, please refer to fig. 12, fig. 12 is a schematic view of a further structure of the lens 34 shown in fig. 6 along A-A line. The lens includes a lens barrel 341 and a lens group 342 disposed in the lens barrel 341.

The second lens 3422 is located on the object-side of the first lens 3421, and the third lens 3423 is located on the image-side of the first lens 3421.

In the present embodiment, the lens group 342 including the first lens 3421, the second lens 3422, and the third lens 3423 is described as an example, but this is not meant to be a particular limitation of the present application. In other embodiments, the lens group 342 may include only one or two of the first, second, and third lenses 3421, 3422, 3423, and the lens group 342 may include multiple sets of the first, second, and third lenses 3421, 3422, 3423.

In order to develop miniaturization and miniaturization of the camera module 30, the volume of the camera module 30 is smaller and smaller. Therefore, the space occupied by the lens group 342 can be reduced by performing a trimming process on the non-effective portion 3421b of the lens. In practical use, the trimming process is performed on a part of the lenses of the lens group 342 having a larger diameter, and the number of lenses subjected to the trimming process is not limited to one, two, three, or the like. The first lens 3421 is described as an example, but this is not a specific limitation of the present application.

Referring to fig. 18 and 19 together, fig. 19 is a schematic structural diagram of the first lens 3421 shown in fig. 18 when viewed from the F1 angle. After the first lens 3421 is subjected to the trimming process, an outer peripheral edge 342c of the first lens 3421 forms an arc-shaped edge Y1 and a flattened edge Y2. The arcuate edge Y1 is a portion of the outer peripheral edge 342c of the first lens 3421 which is not trimmed, and the flat edge Y2 is a portion of the outer peripheral edge 342c of the first lens 3421 which is trimmed.

Referring to fig. 23, fig. 23 is a schematic structural diagram of the lens barrel 341 shown in fig. 21 applied to the electronic device 100. The second carbon nanotube layer 392 has an effect of improving the appearance of the electronic device 100 in addition to the effect of avoiding the generation of stray light as described above. Specifically, after the lens barrel 341 is disposed in the housing of the electronic device 100, the housing has a light-transmitting window 51 for communicating with the light-entering opening 341a of the lens barrel, and the diameter of the light-transmitting window 51 is slightly larger than the light-entering opening 341a of the lens barrel 341, so that the first end surface 341d and at least a portion of the outer peripheral surface of the lens barrel 341 are also exposed to the light-transmitting window 51. The second carbon nanotube layer 392 is disposed on the first end surface 341d and at least a portion of the outer peripheral surface, so that the electronic device 100 can be ensured to exhibit a high-level black effect at the position of the camera module 30, and the aesthetic property of the electronic device 100 is improved. And the second carbon nanotube layer 392 can also ensure that the effect of high-grade black can be presented when observed at any angle, and color change can not occur due to different observation angles, such as red, purple, gold and the like, which is a further effect compared with the ink coating.

In some embodiments, the lens further includes a third carbon nanotube layer 393, and the third carbon nanotube layer 393 is disposed at least on a portion of the inner wall 341e of the lens barrel 341. In this way, when the light irradiates the inner wall 341e of the lens cone 341, the third carbon nanotube layer 393 absorbs the light, so as to avoid the phenomenon that the light irradiated to the inner wall 341e of the lens cone 341 is reflected or scattered, further avoid the generation of stray light, improve the shooting effect of the camera module 30, and further improve the use experience of the user.

Specifically, the first spacer abuts against the second surface area M12 of the first lens 3421, and the second spacer abuts against the third surface area M13 of the first lens 3421. Referring to fig. 26, fig. 26 is a schematic diagram of another structure of a barrier 344 in the lens shown in fig. 24. The spacer thickness is smaller and the spacing between adjacent lenses is smaller than would be possible with the spacer spacing. When the distance between the adjacent lenses is larger, the baffle part can be a spacer ring, and the spacer ring has larger thickness compared with the spacer, so that the adjacent two lenses with larger distance can be conveniently spaced.

In the shooting process of the camera module 30, a part of light may also irradiate the baffle 344, so as to avoid the problem that stray light is generated due to reflection or scattering of the part of light on the baffle 344, the lens barrel 341 further includes a fourth carbon nanotube layer 394, and the fourth carbon nanotube layer 394 is disposed on the surface of the baffle 344, so that when the light irradiates the baffle 344, the fourth carbon nanotube layer 394 absorbs the light irradiated on the baffle 344, thereby avoiding the generation of stray light, improving the shooting effect of the camera module 30, and further improving the use experience of a user.

The filter 311 may be, but is not limited to, a blue glass filter. For example, the filter 311 may be a reflective infrared filter, or a dual-pass filter (the dual-pass filter may transmit both visible light and infrared light in the ambient light, or transmit both visible light and light of other specific wavelengths (such as ultraviolet light), or transmit both infrared light and light of other specific wavelengths (such as ultraviolet light).

With continued reference to fig. 5, and with reference to fig. 28, fig. 28 is a schematic structural diagram of the filter holder 312 in the camera module 30 shown in fig. 5.

Alternatively, the lens 34 may not be provided with the lens barrel 341, and the lens group 342 of the lens 34 may be mounted and fixed in the lens mounting hole 321 of the carrier 32. The lens set 342 is thereby fixed and protected by the carrier 32 to integrate the carrier 32 with the lens 34, which is beneficial to reduce the volume of the camera module 30.

Referring to fig. 27, fig. 27 is an assembly diagram of the lens 34 and the carrier 32 in the camera module 30 shown in fig. 5.

The base includes a receiving space for supporting and fixing other components in the camera module 30, and the receiving space may be enclosed by a wall plate or a column. The base can be cuboid, cube, cylinder etc.

During the use of the camera module 30, a part of light will be reflected and scattered on the outer surface and the inner surface of the base, and a part of the reflected and scattered light will enter the lens cone 341, thereby generating stray light. Therefore, in order to avoid the occurrence of this problem, set up the carbon nanotube layer on the surface and the internal surface of base, absorb light through the carbon nanotube layer, avoid the emergence reflection or the scattering of light on the surface and the internal surface of base, and then promote the shooting effect of camera module 30, promote user's use experience.
