Description
Technical Field

Background
The filter is an additional lens which is arranged in front of the camera and is used for filtering natural light entering the camera. In the photographic creation process, the use frequency of two filters is very high, namely a light-reducing lens and a gradual-change lens.

Detailed Description
For the purposes of clarity, technical solutions and advantages of the present disclosure, the following further details the embodiments of the present disclosure with reference to the accompanying drawings.
The filter is an additional lens which is arranged in front of the camera and is used for filtering natural light entering the camera. In the photographic creation process, the use frequency of two filters is very high, namely a light-reducing lens and a gradual-change lens.
The light-reducing lens has lower overall light transmittance, so that the light incoming quantity of the camera can be reduced overall. Dimming mirrors are typically used in the following scenarios: 1. overexposure is prevented in a strong light environment; 2. the light quantity is reduced in a bright light environment, so that the dynamic effect can be shot at a lower shutter speed; 3. stray light is reduced, and color saturation is improved.
The light transmittance of the partial area of the gradual change mirror gradually decreases along a certain direction, so that the light entering quantity of the camera can be gradually reduced in the partial area. Progressive mirrors are commonly used in the following scenarios: when shooting scenery, the light intensity difference between the sky part and the ground part is larger, the partial area with gradually reduced light transmittance of the gradual change mirror is aligned to the sky, so that the light incoming quantity of the sky part is reduced, and the partial area with normal light transmittance of the gradual change mirror is aligned to the ground, so that the light incoming quantity of the ground part is kept unchanged. In this way, the light intensity difference between the sky part and the ground part is reduced, so that a better picture is taken.
In the related art, the light reducing lens and the progressive lens are two independent filters, which can be detachably mounted on the camera, respectively. When the dimming mirror is needed, the dimming mirror is mounted on the camera, and when the gradual change mirror is needed, the dimming mirror is dismounted, and then the gradual change mirror is mounted on the camera.
However, the above-mentioned disassembly and assembly process is complicated, and the disassembled filter is inconvenient to preserve.
In order to solve the above technical problems, an embodiment of the present disclosure provides a filter, fig. 1 is a perspective sectional view of the filter, and fig. 1 is a cut-out half of the filter so as to show an internal structure of the filter. Referring to fig. 1, the filter comprises a first light-transmitting plate 1, and a color-changing interlayer 2 and a second light-transmitting plate 3 which are sequentially stacked on the first light-transmitting plate 1. The color-changing interlayer 2 has a plurality of electrochromic regions 2a, and each electrochromic region 2a is arranged at intervals in sequence along a direction parallel to the surface of the first light-transmitting plate 1.
When photographing is assisted by the filter provided by the embodiment of the present disclosure, if the filter needs to be used as a light-reducing lens, the same voltage and current are output to all electrochromic regions 2 a. Based on the characteristics of the electrochromic material, the voltage and current are directly proportional to the degree to which the transmittance of the electrochromic regions 2a is reduced. Therefore, the light transmittance of each electrochromic region 2a will decrease to the same extent, thereby reducing the overall light entering amount of the camera.
If the filter is required to be used as a progressive mirror, the partial electrochromic regions 2a are electrified according to the requirement, and the electrified voltage and current are gradually increased or decreased along the arrangement direction of each electrochromic region 2a, so that the light transmittance of the partial electrochromic regions 2a is gradually reduced or increased along the arrangement direction, and the light inlet amount of the camera can be gradually reduced in the partial regions.
If a filter is not required, it is only necessary to keep all electrochromic regions 2a unpowered.
Therefore, the filter provided by the embodiment of the disclosure has the functions of both the light-reducing lens and the gradual change lens. In addition, when the function is switched, the disassembly and assembly are not needed, and only the voltage and the current of the electrochromic region 2a are needed to be changed, so that the use is simple and convenient.
With continued reference to fig. 1, in this embodiment, the color-changing interlayer 2 includes a first color-changing layer 21, an intermediate light-transmitting plate 22, and a second color-changing layer 23 stacked in this order on the first light-transmitting plate 1.
The first color-changing layer 21 includes n first electrochromic modules 211, n is equal to or greater than 2, and n is an integer. The second electrochromic layer 23 comprises m second electrochromic modules 231, m is more than or equal to 2, m is an integer, m-n is less than or equal to 1, and n first electrochromic modules 211 and m second electrochromic modules 231 are alternately and adjacently arranged in sequence along the direction parallel to the surface of the first light-transmitting plate 1.
By way of example, the arrangement of the first electrochromic module 211 and the second electrochromic module 231 will be described below:
For example, if n is 4, then m is 3,4, or 5. When n is 4 and m is 3, the first electrochromic module 211 and the second electrochromic module 231 are arranged as shown in fig. 2. When n is 4 and m is 4, the first electrochromic module 211 and the second electrochromic module 231 are arranged as shown in fig. 3. When n is 4 and m is 5, the first electrochromic module 211 and the second electrochromic module 231 are arranged as shown in fig. 4.
When photographing is assisted by the filter provided by the embodiment of the present disclosure, if the filter needs to be used as a light-reducing lens, the same voltage and current are output to all the first electrochromic module 211 and the second electrochromic module 231. Since the voltage and current are directly proportional to the degree to which the light transmittance of the first and second electrochromic modules 211 and 231 is reduced, the light transmittance of the first and second electrochromic modules 211 and 231 will be reduced by the same degree, thereby reducing the overall light input amount of the camera.
If the filter is required to be used as a progressive mirror, the first electrochromic module 211 and the second electrochromic module 231 in the partial area are electrified according to the requirement, and the electrified voltage and current are gradually increased or decreased along the arrangement direction of the first electrochromic module 211 and the second electrochromic module 231, so that the light transmittance of the first electrochromic module 211 and the second electrochromic module 231 in the partial area is gradually reduced or increased along the arrangement direction, and the light input amount of the camera can be gradually reduced in the partial area.
If a filter is not required, all of the first electrochromic module 211 and the second electrochromic module 231 need only be kept unpowered.
Therefore, the filter provided by the embodiment of the disclosure has the functions of both the light-reducing lens and the gradual change lens. In addition, during function switching, the first electrochromic module 211 and the second electrochromic module 231 only need to be changed in voltage and current without disassembly and assembly, and the use is simple and convenient.
Also, since the first electrochromic module 211 is located between the first light-transmitting plate 1 and the intermediate light-transmitting plate 22 and the second electrochromic module 231 is located between the second light-transmitting plate 3 and the intermediate light-transmitting plate 22, the first electrochromic module 211 and the second electrochromic module 231 are independent from each other, and thus, a problem of mutual influence does not occur.
Of course, in other embodiments, the number of the color-changing layers and the light-transmitting plates included in the color-changing interlayer 2 can be adjusted according to the requirement, for example, the color-changing interlayer comprises three color-changing layers and two light-transmitting plates, and the two light-transmitting plates are respectively sandwiched between two adjacent color-changing layers. The application is not limited in this regard.
As can be seen from the foregoing, the first electrochromic module 211 and the second electrochromic module 231 play a key role, and the first electrochromic module 211 and the second electrochromic module 231 are described below.
Fig. 5 is a view in a direction a of fig. 1, and in combination with fig. 5, in the present embodiment, each of the first electrochromic module 211 and the second electrochromic module 231 includes a first transparent conductive layer 51, an electrochromic layer 52, an electrolyte layer 53, an ion storage layer 54, and a second transparent conductive layer 55.
The first transparent conductive layer 51 of the first electrochromic module 211 is attached to the first transparent plate 1, and the electrochromic layer 52, the electrolyte layer 53, the ion storage layer 54 and the second transparent conductive layer 55 of the first electrochromic module 211 are sequentially stacked on the first transparent conductive layer 51 of the first electrochromic module 211, and the second transparent conductive layer 55 of the first electrochromic module 211 is attached to the intermediate transparent plate 22.
The first transparent conductive layer 51 of the second electrochromic module 231 is attached to the intermediate light-transmitting plate 22, and the electrochromic layer 52, the electrolyte layer 53, the ion storage layer 54 and the second transparent conductive layer 55 of the second electrochromic module 231 are sequentially stacked on the first transparent conductive layer 51 of the second electrochromic module 231, and the second transparent conductive layer 55 of the second electrochromic module 231 is attached to the second light-transmitting plate 3.
In the following description, the first electrochromic module 211 is taken as an example, and the electrochromic layer 52 has an electrochromic material therein, which can change its light transmittance by the action of an external electric field during the color change process. The electrolyte layer 53 serves to conduct ions during the color change process while insulating electrons. The ion storage layer 54 is used to balance ions, provide and store ions required for color change. When the transmittance of the first electrochromic module 211 needs to be changed, a certain voltage is applied between the first transparent conductive layer 51 and the second transparent conductive layer 55, and the electrochromic layer 52 undergoes an oxidation-reduction reaction under the action of the voltage, so that the transmittance of the first electrochromic module 211 changes.
Alternatively, the ion storage layer 54 is an electrochromic material having a color change property opposite to that of the electrochromic material of the electrochromic layer 52, which can function as a color overlay or complement. For example: the electrochromic material of electrochromic layer 52 is an anodized color-changing material, and the electrochromic material of ion storage layer 54 is a cathodically reduced color-changing material.
Since the structure of the second electrochromic module 231 is substantially the same as that of the first electrochromic module 211, the working principle is also substantially the same, and the difference is only the position in the filter, which is not described herein.
With continued reference to fig. 5, in the present embodiment, the first color-changing layer 21 further includes a first transparent optical paste 212, and the first transparent optical paste 212 is filled in the gaps between the n first electrochromic modules 211. The second color-changing layer 23 further includes a second transparent optical paste 232, and the second transparent optical paste 232 is filled in gaps between the m second electrochromic modules 231.
In the above implementation manner, the first transparent optical adhesive 212 is filled in the gaps between the n first electrochromic modules 211, so that the first light-transmitting plate 1 and the middle light-transmitting plate 22 can be more firmly connected, and unnecessary displacement of the first electrochromic modules 211 is avoided. The second transparent optical adhesive 232 is filled in the gaps among the m second electrochromic modules 231, so that the second light-transmitting plates 3 and the middle light-transmitting plates 22 can be more firmly connected, and unnecessary displacement of the second electrochromic modules 231 is avoided. Therefore, the structural stability of the filter can be effectively improved by filling the first transparent optical cement 212 and the second transparent optical cement 232.
Since the first light-transmitting plate 1 and the intermediate light-transmitting plate 22 are spaced apart from each other, a first accommodating space 61 is provided therebetween, and n first electrochromic modules 211 are disposed in the first accommodating space 61. The first transparent optical cement 212 is filled in the first accommodating space 61. For the same reason, there is a second accommodation space 62 between the second light-transmitting plate 3 and the intermediate light-transmitting plate 22, and m second electrochromic modules 231 are located in the second accommodation space 62. The second transparent optical cement 232 is filled in the second accommodating space 62.
It should be noted that the first transparent optical adhesive 212 does not exceed the outer edges of the first light-transmitting plate 1 and the intermediate light-transmitting plate 22, and the second transparent optical adhesive 232 does not exceed the outer edges of the second light-transmitting plate 3 and the intermediate light-transmitting plate 22. In addition, since the first transparent optical cement 212 and the second transparent optical cement 232 are both high-transmittance optical cement, the transmission of light is not affected.
Fig. 6 is an exploded view of the first light-transmitting plate 1, the intermediate light-transmitting plate 22, and the second light-transmitting plate 3, and the first color-changing layer 21 and the second color-changing layer 23 are omitted in fig. 6 for better showing the first light-transmitting plate 1, the intermediate light-transmitting plate 22, and the second light-transmitting plate 3. Referring to fig. 6, in the present embodiment, each of the first light-transmitting plate 1, the second light-transmitting plate 3, and the intermediate light-transmitting plate 22 has a light-transmitting region 4, and the orthographic projections of the light-transmitting region 4 of the intermediate light-transmitting plate 22 and the light-transmitting region 4 of the second light-transmitting plate 3 on the first light-transmitting plate 1 coincide with the light-transmitting region 4 of the first light-transmitting plate 1. The orthographic projections of the n first electrochromic modules 211 and the m second electrochromic modules 231 on the first light-transmitting plate 1 coincide with the light-transmitting areas 4 of the first light-transmitting plate 1 (see fig. 1).
In the above implementation manner, the light-transmitting area 4 is an area where light can enter the camera through the filter, and since the orthographic projections of the n first electrochromic modules 211 and the m second electrochromic modules 231 on the first light-transmitting plate 1 overlap with the light-transmitting area 4 of the first light-transmitting plate 1, all the light entering the camera through the filter will pass through the first electrochromic modules 211 or the second electrochromic modules 231. In this way, the first electrochromic module 211 and the second electrochromic module 231 can sufficiently filter all the light entering the camera, so as to improve the use effect of the filter.
Fig. 7 is a top view of the filter, referring to fig. 7, the first light-transmitting plate 1, the intermediate light-transmitting plate 22, and the second light-transmitting plate 3 are exemplarily circular plate members having the same area and are coaxial with each other. The light-transmitting area 4 is circular, and the light-transmitting area 4 is coaxial with the first light-transmitting plate 1.
The first light-transmitting plate 1, the second light-transmitting plate 3, the middle light-transmitting plate 22 and the light-transmitting region 4 are designed to be circular, and circular characteristics can be utilized, so that the area of the light-transmitting region 4 is large enough in a limited space to be designed according to actual requirements. In addition, the areas of the first light-transmitting plate 1, the second light-transmitting plate 3 and the middle light-transmitting plate 22 are the same and coaxial, so that the outer edges of the first light-transmitting plate 1, the second light-transmitting plate 3 and the middle light-transmitting plate 22 are flush, the structure is more compact, and the required installation space is reduced.
Illustratively, the first light-transmitting plate 1, the second light-transmitting plate 3 and the intermediate light-transmitting plate 22 are all glass plates. So designed, the light transmittance of the first light-transmitting plate 1, the second light-transmitting plate 3 and the middle light-transmitting plate 22 can be ensured, and the structural strength of the first light-transmitting plate 1, the second light-transmitting plate 3 and the middle light-transmitting plate 22 can be ensured, so that the first electrochromic module 211 and the second electrochromic module 231 are stably supported, and the stability of the filter is ensured.
The disclosed embodiment provides a mobile terminal, fig. 5 is a front view of the mobile terminal, fig. 9 is a B-B cross-sectional view of fig. 5, and the mobile terminal includes a housing 100, a camera 200, and a filter 300 in combination with fig. 5.
The wall of the housing 100 has a through hole 110, the camera 200 is located in the housing 100 and is opposite to the through hole 110, the camera 200 is connected to the inner side of the wall, the filter 300 is the filter shown in fig. 1-7, and the filter 300 is located in the through hole 110.
When shooting is performed by the mobile terminal provided by the embodiment of the present disclosure, light enters the camera 200 through the filter 300 in the through hole 110. If it is necessary to use the filter 300 as a light reducing mirror, the same voltage and current are output to all the first and second electrochromic modules 211 and 231. Since the voltage and current are directly proportional to the degree to which the light transmittance of the first and second electrochromic modules 211 and 231 is reduced, the light transmittance of the first and second electrochromic modules 211 and 231 will be reduced by the same degree, thereby reducing the overall light input amount of the camera 200.
If the filter 300 is required to be used as a progressive mirror, the first electrochromic module 211 and the second electrochromic module 231 in the partial areas are electrified according to the requirement, and the electrified voltage and current are gradually increased or decreased along the arrangement direction of the first electrochromic module 211 and the second electrochromic module 231, so that the light transmittance of the first electrochromic module 211 and the second electrochromic module 231 in the partial areas is gradually reduced or increased along the arrangement direction, and the light input amount of the camera 200 can be gradually reduced in the partial areas.
If the filter 300 is not used, it is only necessary to keep all the first electrochromic modules 211 and the second electrochromic modules 231 from being powered.
It can be seen that the mobile terminal provided in the embodiments of the present disclosure has the function of both the light-reducing lens and the progressive lens of the filter 300. In addition, during function switching, the first electrochromic module 211 and the second electrochromic module 231 only need to be changed in voltage and current without disassembly and assembly, and the use is simple and convenient.
In this embodiment, the inner peripheral wall of the through hole 110 has an annular clamping groove 120, the clamping groove 120 extends along the circumferential direction of the through hole 110, and the outer edge of the filter 300 is inserted into the clamping groove 120. By such a design, the filter 300 can be stably mounted on the housing 100 through the clamping groove 120. When the filter 300 is inserted into the clamping groove 120, the first light-transmitting plate 1 and the second light-transmitting plate 3 of the filter 300 respectively abut against the inner groove wall of the clamping groove 120.
In other embodiments, the filter 300 can be mounted in the through hole 110 in other ways, for example, referring to fig. 10, the view of fig. 10 is the same as fig. 9, and the inner peripheral wall of the through hole 110 is bonded to the outer edge of the filter 300. By such design, the processing difficulty can be simplified without providing the annular clamping groove 120 on the inner peripheral wall of the through hole 110.
Optionally, one side of the filter 300 contacts with the camera 200, that is, the first light-transmitting plate 1 contacts with the camera 200, so that the filter 300 and the camera 200 are more compact in structure, which is beneficial to the light and thin design of the mobile terminal.
The foregoing description of the preferred embodiments of the present disclosure is provided for the purpose of illustration only, and is not intended to limit the disclosure to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, alternatives, and alternatives falling within the spirit and principles of the disclosure.
