Referring to fig. 1 and 2, an aperture structure 10 according to an embodiment of the present disclosure includes a first transparent substrate 11, a second transparent substrate 12, and a color-changing element 13. The first transparent substrate 11 is disposed opposite to the second transparent substrate 12. The color changing element 13 is disposed between the first transparent substrate 11 and the second transparent substrate 12, and the color changing element 13 is used for changing the degree of light transmission after a voltage is applied thereto to change the light transmittance of the aperture structure 10.

Further, the first transparent substrate 11 and the second transparent substrate 12 may be made of lanthanide glass. The lanthanide glass has high light transmittance and true color restoration. It is to be understood that the first transparent substrate 11 and the second transparent substrate 12 may be made of not only lanthanide glass, but also different materials for the first transparent substrate 11 and the second transparent substrate 12 according to different situations. For example, the first transparent substrate 11 and the second transparent substrate 12 may also be made of optical glass or resin lens. Specific materials of the first transparent substrate 11 and the second transparent substrate 12 are not limited herein.

In this embodiment, the same material may be selected for the first transparent substrate 11 and the second transparent substrate 12, but of course, in other embodiments, the first transparent substrate 11 and the second transparent substrate 12 may be made of different materials. It is not limited whether the first transparent substrate 11 and the second transparent substrate 12 are made of the same material.

Further, the first transparent substrate 11 and the second transparent substrate 12 are rectangular, and of course, the first transparent substrate 11 and the second transparent substrate 12 may not only be rectangular, but also the shape of the first transparent substrate 11 and the second transparent substrate 12 may be set according to different situations. For example, the first and second

transparent substrates

11 and 12 may also be circular. The specific shapes of the first transparent substrate 11 and the second transparent substrate 12 are not limited herein.

Referring to fig. 2 to 4, in some embodiments, the number of the color-changing elements 13 is multiple, the color-changing elements 13 are all annular, and the color-changing elements 13 are sleeved with each other.

The annular color-changing element 13 can realize faster electrochromic response, and the arrangement of the annular structure can enable the structure of the diaphragm structure 10 to be more compact, so that the miniature production of the diaphragm structure 10 is realized.

Further, the color-changing element 13 is an electrochromic material, and the electrochromic material generates a stable and reversible color change phenomenon under the action of an external electric field, and shows reversible changes of color and transparency in appearance. This enables the color changing element 13 to achieve a change in the degree of light transmission to change the light transmission of the aperture structure 10. Thereby achieving the purpose of varying the light transmittance of the aperture structure 10.

Specifically, the color changing element 13 is composed of an electrochromic layer, an electrolyte layer, and an ion storage layer.

The material of the electrochromic layer can be selected from one or more of tungsten oxide, molybdenum oxide, titanium oxide, prussian blue, polythiophene, viologen and the like, of course, the material of the electrochromic layer is not only a single choice or a combination of the materials, but also can be made of other materials under different conditions. The specific material of the electrochromic layer is not limited herein.

The electrolyte layer can be made of one or more materials selected from lithium tantalate, lithium zirconate, lithium niobate, gel electrolyte containing lithium perchlorate, and the like, and of course, the material of the electrolyte layer is not only a single choice or a combination of the above materials, but also can be made of other materials in different cases. The specific material of the electrolyte layer is not limited herein.

The ion storage layer comprises one or more of nickel oxide NiO, polyaniline and the like. It will be appreciated that the material of the ion storage layer is not only a single selection or a plurality of combinations of the above materials, but that other material compositions may be used for the ion storage layer in different cases. The specific material of the ion storage layer is not limited herein.

Wherein, electrochromic layer, electrolyte layer and ion storage layer set up from bottom to top in proper order. Of course, the electrochromic layer, the electrolyte layer and the ion storage layer may not only be sequentially disposed from bottom to top, but also may be disposed according to different situations. The specific locations of the electrochromic layer, the electrolyte layer, and the ion storage layer are not limited herein.

Further, the color changing element 13 may include not only an electrochromic layer, an electrolyte layer, an ion storage layer. Different structures can be added to the color change element 13 in different situations. The specific composition of the color changing element 13 is not limited herein.

In this embodiment, the number of the color changing elements 13 is 3, but in other embodiments, the number of the color changing elements 13 may be set not only to 3, but also to the extent that the number of the color changing elements 13 is set in accordance with the circumstances. For example, the number of color-changing elements 13 may also be 1, 2, 4, or 6, etc. The specific number of color-changing elements 13 is not limited herein.

In some embodiments, a gap 14 is formed between two adjacent color changing elements 13.

A gap 14 is formed between two adjacent color-changing elements 13, so that the abnormal change of the light transmission degree of the color-changing elements 13 caused by the exchange of the electric quantity between two adjacent color-changing elements 13 in the electrifying process can be prevented. Thereby improving the operational stability of the aperture structure 10.

In some embodiments, two adjacent color change elements 13 are disposed in an insulating manner.

The insulating arrangement between two adjacent color-changing elements 13 can further prevent the abnormal situation that the change of the light transmission degree of the color-changing elements 13 is caused by the exchange of the electric quantity between two adjacent color-changing elements 13 in the electrifying process. Thereby improving the operational stability of the aperture structure 10.

In some embodiments, the first transparent substrate 11 is provided with a first conductive electrode 15 connected to the color changing element 13, the second transparent substrate 12 is provided with a second conductive electrode 16 connected to the color changing element 13, and the first conductive electrode 15 and the second conductive electrode 16 are used for applying a voltage to the color changing element 13 in cooperation.

The first conductive electrode 15 and the second conductive electrode 16 are electrified to enable the color-changing element 13 to generate stable and reversible color changes, so that the light transmission degree of the color-changing element 13 changes.

In other embodiments, the first conductive electrode 15 may be omitted, i.e. the aperture structure 10 comprises only the second conductive electrode 16.

In some embodiments, the number of color-changing elements 13 is the same as the number of second conductive electrodes 16, one end of each color-changing element 13 is connected to the first conductive electrode 15, and the other end of each color-changing element 13 is connected to a corresponding one of the second conductive electrodes 16.

So set up, conveniently control the printing opacity degree of color-changing element 13. Since one end of each color changing element 13 is connected to the first conductive electrode 15 and the other end of each color changing element 13 is connected to only one second conductive electrode 16, the color changing element 13 will have a change in the degree of light transmission only when the first conductive electrode 15 and the second conductive electrode 16 are energized. That is, one color changing element 13 is required to change the degree of light transmission, and only the first conductive electrode 15 and the second conductive electrode 16 corresponding to the color changing element 13 need to be energized. Two color change elements 13 are required to change the degree of light transmission, and only the first conductive electrode 15 and the second conductive electrode 16 corresponding to the color change elements 13 need to be energized. Therefore, the user can adjust the light transmittance of the color-changing element 13 according to the requirement, and the controllability of the change of the aperture structure 10 is improved.

Further, the first conductive electrode 15 and the second conductive electrode 16 may be made of indium tin oxide. The indium tin oxide has high light transmittance and good conductivity, so that the working efficiency of the first conductive electrode 15 and the second conductive electrode 16 can be improved. It is understood that the first conductive electrode 15 and the second conductive electrode 16 may be made of not only indium tin oxide. The materials of the first conductive electrode 15 and the second conductive electrode 16 may be set according to different situations, for example, the first conductive electrode 15 and the second conductive electrode 16 may also be formed by doping tin oxide with fluorine, doping zinc oxide with aluminum, and the like. The specific material of the first conductive electrode 15 and the second conductive electrode 16 is not limited herein.

Specifically, the material of the first conductive electrode 15 and the second conductive electrode 16 may be the same. Of course, in other embodiments, the materials of the first and second

conductive electrodes

15 and 16 may not be the same. No limitation is made to whether the materials of the first conductive electrode 15 and the second conductive electrode 16 are the same.

In some embodiments, the plurality of second conductive electrodes 16 are elongated, each second conductive electrode 16 includes a first pole segment 161 and a second pole segment 162 that are disposed at an interval, and the first pole segment 161 and the second pole segment 162 are respectively connected to two opposite sides of the corresponding color changing element 13.

Because the color changing element 13 is annular, the light transmission hole 17 is formed in the middle of the color changing element 13, and the arrangement of the first pole segment 161 and the second pole segment 162 not only enables the second conductive electrode 16 to be connected with the color changing element 13, but also reduces the usage amount of the second conductive electrode 16, that is, if the second conductive electrode 16 is in a complete strip shape, the second conductive electrode 16 can pass through the light transmission hole 17 of the color changing element 13, and because the color changing element 13 is not arranged at the light transmission hole 17 of the color changing element 13, the second conductive electrode 16 at the light transmission hole 17 can not be utilized, thereby reducing the utilization rate of resources. The second conductive electrode 16 adopts the first pole segment 161 and the second pole segment 162 to effectively improve the utilization rate of resources, reduce the manufacturing cost of the aperture structure 10, and facilitate the mass production of the aperture structure 10.

The arrangement of the first pole segment 161 and the second pole segment 162 can also improve the response time of the color changing element 13, thereby improving the working efficiency of the aperture structure 10.

Further, the first pole segment 161 and the second pole segment 162 are rotationally symmetric.

As shown in fig. 3, assuming that the number of the second conductive electrodes 16 is 3, the number of the color-changing elements 13 is 3, and the first pole segment 161 and the second pole segment 162 of each second conductive electrode 16 are oppositely disposed, it can be seen from the figure that, taking the innermost color-changing element 13 as an example, the innermost color-changing element 13 is a, and the color-changing element a is corresponding to the second conductive electrode 16, in which case, the first pole segment 161 corresponding to the second conductive electrode 16 is a1, and the second pole segment 162 is a2, and the color-changing element a is in a ring shape, if the first pole segment a1 and the second pole segment a2 are oppositely disposed, the arc length b1 and the arc length b2 of the color-changing element a may be different, and when the first pole segment a1 and the second pole segment a2 are energized, the rate of electrons in the color-changing element a from the first pole segment a1 to the second pole segment a2 may be different, and the color-changing response of the color-changing element 13 may be slow.

As shown in fig. 4, assuming that the number of the second conductive electrodes 16 is 3, the number of the color change elements 13 is 3, and the first pole segment 161 and the second pole segment 162 of each second conductive electrode 16 are rotationally symmetrically arranged, it can be seen from the figure that, assuming that the innermost color change element 13 is B, and the color change element B corresponds to the second conductive electrode 16, at this time, the first pole segment 161 corresponding to the second conductive electrode 16B is B1, and the second pole segment 162 is B2, and the color change element B is annular, if the first pole segment B1 and the second pole segment B2 are rotationally symmetrically arranged, the arc length c1 and the arc length c2 of the color change element B can be made the same, and when the first pole segment B1 and the second pole segment B2 are energized, electrons will have the same speed from the first pole segment B1 to the second pole segment B2, so that the color change response of the color change element 13 can be accelerated.

It is understood that the first pole segment 161 and the second pole segment 162 may not only be arranged in a rotational symmetry or in an opposite arrangement, but the positions of the first pole segment 161 and the second pole segment 162 may be arranged according to different situations. The specific positions of the first pole segment 161 and the second pole segment 162 are not limited herein.

Referring to fig. 1 and 2, in some embodiments, the aperture structure 10 further includes an insulating film 18 disposed on the second transparent substrate 12 and covering the second conductive electrode 16, and the plurality of color-changing elements 13 are disposed through the insulating film 18 and contact the second conductive electrode 16.

The arrangement of the insulating film layer 18 can prevent different color-changing elements 13 from being connected with the same second conductive electrode 16, thereby improving the controllability of the color-changing elements 13.

Further, referring to fig. 1, a plurality of contact holes 181 are formed on the insulating film 18, and the color-changing elements 13 at different positions are connected to the corresponding second conductive electrodes 16 through the contact holes 181.

Specifically, the contact hole 181 may be circular. It is understood that the contact hole 181 may not be only circular. The shape of the contact hole 181 may be set according to various situations. For example, the contact hole 181 may also be triangular, square, or the like, and the specific shape of the contact hole 181 is not limited herein.

Referring to fig. 2, in some embodiments, the insulating film 18 is formed with a through hole 182, the color-changing element 13 of the innermost layer is formed with a light hole 17, and the light hole 17 is aligned with the through hole 182.

The alignment of the light-transmissive holes 17 and the through holes 182 enables the aperture structure 10 to perform a light-feeding function when not energized.

In some embodiments, the aperture structure 10 further comprises an encapsulation element 19, the encapsulation element 19 surrounding the plurality of color changing elements 13 to encapsulate the plurality of color changing elements 13.

The encapsulation element 19 can encapsulate the color-changing element 13, so that the color-changing element 13 is isolated from substances such as external moisture, and the substances such as external moisture are prevented from being attached to the color-changing element 13, so that the color-changing element 13 is prevented from being damaged, and the service life of the aperture structure 10 is prolonged.

Further, the encapsulation element 19 may be an encapsulation glue. It is understood that the encapsulation element 19 is not limited to the encapsulation glue, and the material of the encapsulation element 19 may be set according to different situations, and the specific type of the encapsulation element 19 is not limited herein.

The diaphragm structure 10 operates according to the principle that in the initial state the color change element 13 is in the open transparent state, in which the diaphragm is at its maximum. When a smaller aperture is needed, the first conductive electrode 15 and the second conductive electrode 16 are conducted, the same negative voltage is applied to the second conductive circuit which controls the same color-changing element 13, at this time, the color-changing element 13 has an electrochromic effect, the light transmittance is reduced, the light is blocked, and the aperture is reduced. Since each color-changing element 13 is independently connected with the second conductive electrode 16, the color-changing elements can be independently controlled, and different aperture sizes can be controlled and selected from the outside to the inside. When a smaller aperture is needed, the first conductive electrode 15 and the second conductive electrode 16 are conducted, the same positive voltage is applied to the second conductive circuit which controls the same color-changing element 13, at this time, the light transmittance of the color-changing element 13 is enhanced due to the electrochromic effect, and light can pass through, so that the aperture becomes larger.

Referring to fig. 5, a camera 100 according to an embodiment of the present disclosure includes a lens barrel 101 and the aperture structure 10, where the aperture structure 10 is disposed on the lens barrel 101.

The aperture structure 10 in the camera 100 of the embodiment of the present application can change the state of the color changing element 13 through circuit control, so as to change the structure of the aperture, and change the size of the aperture, which is beneficial to the miniaturization of the aperture structure 10 and the enhancement of the controllability of the aperture structure 10, and facilitates the setting of the aperture on consumer electronics such as mobile phones and notebook computers.

Further, an accommodating space 102 is provided in the lens barrel 101, and the aperture structure 10 is disposed in the accommodating space 102.

Further, the lens barrel 101 is provided with a light inlet hole 103, and the diameter of the light inlet hole 103 is similar to the diameter of the outermost color-changing element 13 of the aperture structure 10.

Specifically, the lens barrel 101 may be made of plastic. The plastic is more flexible and cheaper, and the lens barrel 101 is made of plastic, which is beneficial to mass production of the camera 100. It is to be understood that the lens barrel 101 may be made of plastic, and the material of the lens barrel 101 may be set according to different situations. For example, the lens barrel 101 may be made of a metal material such as stainless steel. The specific material of the lens barrel 101 is not limited herein.
