[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0034] In the related art, a scattering film is arranged on the light-emitting surface of the optical lens, so that the light passing through the scattering film can be scattered, thereby expanding the range of light entering the optical sensor, thereby expanding the field of view. The maximum value of the field of view angle depends on the size of the lens and the angle between the lines connecting the edges of the optical sensor. However, the size of the lens cannot be infinite due to its structure and appearance, so the angle range is generally less than 90 degrees. If the field of view angle needs to be increased, the opening size of the lens needs to be forcibly increased.

[0035] In addition, the light scattered by the scattering film is randomly radial. Most of the light in the center of the lens can be received by the optical sensor, but most of the light at the edge is scattered outside the sensor, reducing the imaging effect of the edge of the photographic image.

[0036] In order to solve the above technical problems, according to an embodiment of the present disclosure, a lens assembly, a light emitting assembly, a sensor, a camera module and an electronic device are provided, wherein the lens assembly comprises: a lens, comprising a light-transmitting bottom surface and a side surface, wherein the bottom surface faces the light-incoming side, and the side surface intersects with the bottom surface, and the lens has a hollow portion formed by the bottom surface and the side surface, and the hollow portion contains a light-transmitting medium; a first electrode and a second electrode with opposite polarities, wherein the first electrode is arranged on the bottom surface of the lens, and the second electrode is arranged on the side surface of the lens, wherein an electric field is generated between the first electrode and the second electrode, and the light-transmitting medium is located in the electric field, and the electric field ionizes the light-transmitting medium so that the refractive index of the light-transmitting medium after ionization changes.

[0037] The present invention provides a light-transmitting medium in the lens, applies an electric field to the light-transmitting medium through a first electrode and a second electrode, thereby controlling the density distribution of the light-transmitting medium in the lens, so that light passing through the lens can be deflected, thereby achieving a change in the field of view angle.

[0038] It can be understood that the lens assembly involved in the present disclosure can be applicable to any terminal listed below.

[0039] It is understandable that the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (User Equipment, UE), a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal, MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: a smart phone (Mobile Phone), a pocket computer (Pocket Personal Computer, PPC), a handheld computer, a personal digital assistant (Personal Digital Assistant, PDA), a laptop computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0040] Figure 1 It is a schematic structural diagram of a lens assembly according to an exemplary embodiment. Figure 2 The figure is a schematic structural diagram of a lens assembly with electrodes removed according to an exemplary embodiment.

[0041] In some embodiments, Figure 1 and Figure 2 As shown, the lens assembly may include: a lens 10 , a light-transmitting medium 20 , a first electrode 31 and a second electrode 32 .

[0042] The lens 10 may be a light-transmitting component, and may include a light-transmitting bottom surface and a side surface 11, wherein the bottom surface may face the light-incoming side, and light may enter the lens 10 from the light-incoming side. The side surface 11 may intersect the bottom surface.

[0043] The lens 10 may have a hollow portion, which may be formed by the bottom surface and the side surface 11, and the hollow portion may contain a light-transmitting medium 20. The light-transmitting medium 20 may be a filling medium having light transmittance.

[0044] The first electrode 31 can be disposed on the bottom surface of the lens 10, and the second electrode 32 can be disposed on the side surface 11 of the lens 10. When the first electrode 31 and the second electrode 32 are energized, an electric field can be generated between the first electrode 31 and the second electrode 32, and the light-transmitting medium 20 can be located in the electric field.

[0045] The light-transmitting medium 20 can be ionized in the electric field to generate ions. Under the action of the electric field, the ions can gather to positions with high or low electric field strength according to the distribution of the electric field. Since the ions gather to specific positions under the action of the electric field, the macroscopic density of the light-transmitting medium 20 can change accordingly. The density of the light-transmitting medium 20 is high in the part with high ion density, and the density of the light-transmitting medium 20 is low in the part with low ion density.

[0046] By changing the density distribution of the light-transmitting medium 20, the refractive index of different parts of the light-transmitting medium 20 can be changed, so that the light path in the light-transmitting medium 20 is refracted, so that the lens 10 can converge a larger or smaller range of light through refraction, thereby expanding or reducing the field of view of the camera module, so that the camera module can change the field of view as needed.

[0047] In some embodiments, Figure 1 and Figure 2 As shown, the light-transmitting medium 20 may be a medium including gas.

[0048] The light-transmitting medium 20 can be ionized in the electric field to generate ions. Under the action of the electric field, the ions can gather to positions with high or low electric field strength according to the distribution of the electric field. Since the ions gather to specific positions under the action of the electric field, the macroscopic density of the light-transmitting medium 20 can change accordingly. The density of the light-transmitting medium 20 is high in the part with high ion density, and the density of the light-transmitting medium 20 is low in the part with low ion density.

[0049] The ion distribution interval of the ionized gas medium is relatively large, and it is easy to gather at a specific position under the action of the electric field and change the local ion density. Therefore, configuring the transparent medium 20 as a gas medium can make it easier for the electric field to change the density distribution of the transparent medium 20.

[0050] The first electrode 31 and the second electrode 32 can attract the ionized light-transmitting medium 20, thereby changing the density distribution of the light-transmitting medium 20 along the light-incoming direction, so that the refractive index of the light-transmitting medium 20 after ionization is changed compared with the refractive index of the light-transmitting medium 20 in the rest state.

[0051] By changing the density distribution of the light-transmitting medium 20, the refractive index of different parts of the light-transmitting medium 20 can be changed, so that the light path in the light-transmitting medium 20 is refracted, so that the lens 10 can converge a larger or smaller range of light through refraction, thereby expanding or reducing the field of view of the camera module, so that the camera module can change the field of view as needed.

[0052] In some embodiments, Figure 1 and Figure 2As shown, the lens 10 may include an upper bottom surface 121 facing the light-incoming side and a lower bottom surface 122 facing away from the light-incoming side, and the light-incoming direction of the lens assembly may be directed from the upper bottom surface 121 to the lower bottom surface 122 .

[0053] The second electrode 32 may be provided with a plurality of protrusions 33 facing the side surface 11 of the lens 10 . The protrusions 33 may be used to increase the electric field strength and attract particles generated by the ionization of the light-transmitting medium 20 .

[0054] When the charge of the conductor and its surrounding environment are the same, the sharper the tip of the conductor, the greater the curvature, the higher the surface charge density, and the stronger the field strength near it. Therefore, by providing a protrusion 33 on the surface of the second electrode 32, the electric field intensity distribution on the surface of the second electrode 32 can be controlled, so that the electric field intensity distribution can be changed by providing a protrusion 33 at different positions of the second electrode 32, thereby changing the aggregation position of the particles generated by the ionization of the light-transmitting medium 20, thereby changing the density distribution of the lens 10 in the light-incoming direction, so that the lens 10 can gather a larger or smaller range of light through refraction, expand or reduce the field angle of the camera module, and enable the camera module to change the field of view as needed.

[0055] In some embodiments, the arrangement density of the plurality of protrusions 33 may gradually increase along the light incident direction, so that the electric field strength of the second electrode 32 may gradually increase along the light incident direction and the density distribution of the light-transmitting medium 20 in the light incident direction may change accordingly.

[0056] Exemplarily, the ions generated by ionization of the light-transmitting medium 20 may be cations, the first electrode 31 may be an anode, the second electrode 32 may be a cathode, the cations may be attracted by the second electrode 32, and the cations may gather at locations with strong electric field strength.

[0057] By gradually increasing the arrangement density of the plurality of protrusions 33 along the light incident direction, the electric field strength of the second electrode 32 can be gradually increased along the light incident direction, and then the density of the cations of the light-transmitting medium 20 in the light incident direction gradually increases, which can increase the density of the light-transmitting medium 20 in the light incident direction on a macro scale.

[0058] Based on the same principle, the arrangement density of the plurality of protrusions 33 also gradually decreases along the light incident direction, so that the electric field strength of the second electrode 32 can gradually decrease along the light incident direction and the density distribution of the light-transmitting medium 20 in the light incident direction changes accordingly.

[0059] By changing the arrangement density of the protrusions 33 in the light-incoming direction, the density distribution of the light-transmitting medium 20 in the light-incoming direction can be changed accordingly, thereby controlling the density distribution of the light-transmitting medium 20 after the first electrode 31 and the second electrode 32 are energized, so that the lens 10 can converge a larger or smaller range of light through refraction, expand or reduce the field of view of the camera module, and enable the camera module to change the field of view as needed.

[0060] In some embodiments, the second electrode 32 may be provided with a plurality of protrusion groups arranged at intervals along the light incident direction, and the protrusion groups may include a plurality of protrusions 33 arranged at intervals along a direction perpendicular to the light incident direction.

[0061] By arranging the protrusions 33 in rows perpendicular to the light incident direction, the ions in the gas medium are evenly distributed on a plane perpendicular to the light incident direction, thereby unifying the field of view change effects in various directions perpendicular to the light incident direction.

[0062] In some embodiments, the protrusion 33 may be one or more of a cone-shaped protrusion, a columnar protrusion or a needle-shaped protrusion.

[0063] When the charge of the conductor and its surrounding environment are the same, the sharper the tip of the conductor, the greater the curvature, the higher the surface charge density, and the stronger the field strength near it. Therefore, by configuring the protrusion 33 on the surface of the second electrode 32 as a cone-shaped protrusion, a columnar protrusion or a needle-shaped protrusion, the electric field intensity distribution on the surface of the second electrode 32 can be controlled, so that the electric field intensity distribution can be changed by providing the protrusion 33 at different positions of the second electrode 32, thereby changing the aggregation position of the particles generated by the ionization of the light-transmitting medium 20, so that the density distribution of the lens 10 in the light-incoming direction can be changed, so that the lens 10 can gather a larger or smaller range of light through refraction, expand or reduce the field angle of the camera module, and enable the camera module to change the field of view as needed.

[0064] In some embodiments, the lens assembly may include an adhesive layer, and the first electrode 31 is connected to the lower bottom surface 122 through the adhesive layer. The adhesive layer may cover the side of the first electrode 31 facing the lower bottom surface 122, so that the adhesive layer can replace the surface of the first electrode 31 facing the light-incoming side, reduce the reflection of the surface of the first electrode 31 on the incident light, and thus increase the amount of light entering the lens 10.

[0065] In some other embodiments, the first electrode 31 may also be disposed on the upper bottom surface 121 .

[0066] In some embodiments, Figure 1 As shown, there may be a plurality of second electrodes 32 , and the plurality of second electrodes 32 may be disposed around the side surface 11 of the lens 10 .

[0067] By arranging multiple second electrodes 32 on the side surface 11 of the lens 10, the electric field distribution in the direction perpendicular to the light incident direction can be made close, and the gas distribution in the direction perpendicular to the light incident direction can be made close, so that the field of view change effects in various directions perpendicular to the light incident direction can be made close, thereby improving the field of view consistency of the photographic image in various directions.

[0068] Exemplarily, the second electrode 32 may include a first sub-electrode 321 and a second sub-electrode 322 , and the first sub-electrode 321 and the second sub-electrode 322 may be disposed opposite to each other on the side surface 11 of the lens 10 .

[0069] In some embodiments, the second electrode 32 may be a ring-shaped member, and the second electrode 32 may surround the lens 10 .

[0070] By arranging the annular second electrode 32 on the side surface 11 of the lens 10, the gas distribution in the direction perpendicular to the light incident direction can be uniform, thereby unifying the field of view change effects in various directions perpendicular to the light incident direction and improving the field of view consistency of the photographic image in various directions.

[0071] In some embodiments, Figure 1 As shown, the first electrode 31 may be an anode, and the second electrode 32 may be a cathode.

[0072] After the light-transmitting medium 20 is ionized, cations may be generated, and the second electrode 32 may attract the cations generated by the ionized light-transmitting medium 20. The cations may be attracted by the second electrode 32, and the cations may be gathered at a location with a strong electric field strength.

[0073] The arrangement density of the plurality of protrusions 33 gradually increases along the light-incoming direction, so that the density of the light-transmitting medium 20 gradually increases along the light-incoming direction. By gradually increasing the arrangement density of the plurality of protrusions 33 along the light-incoming direction, the electric field strength of the second electrode 32 can gradually increase along the light-incoming direction, and then the density of the cations of the light-transmitting medium 20 in the light-incoming direction gradually increases, and the density of the light-transmitting medium 20 in the light-incoming direction can be increased accordingly on a macro scale.

[0074] The incident light L entering the lens 10 can undergo greater refraction when passing through the part of the transparent medium 20 with a higher density, so that the optical path of the incident light L can be deflected in the direction away from the optical axis, so that the lens 10 can converge a larger range of light through refraction, expand the field of view half angle A, expand the field of view angle of the camera module, and enable the camera module to change the field of view as needed.

[0075] By changing the arrangement density of the protrusions 33 in the light-incoming direction, the density distribution of the light-transmitting medium 20 in the light-incoming direction can be changed accordingly, thereby controlling the density distribution of the light-transmitting medium 20 after the first electrode 31 and the second electrode 32 are energized, so that the lens 10 can converge a larger range of light through refraction, expand the field of view half angle A, expand the field of view angle of the camera module, and enable the camera module to change the field of view as needed.

[0076] In some embodiments, the first electrode 31 may be a transparent member, so that the light incident on the lens 10 can pass through the electrode disposed on the bottom surface. Exemplarily, the first electrode 31 may be an electrode composed of indium tin oxide.

[0077] In some embodiments, the light-transmitting medium 20 may include a rare gas, which has stable chemical properties and can be stably restored to the state before ionization after repeated ionization, thereby increasing the service life of the lens 10. Exemplarily, the light-transmitting medium 20 may include helium or argon.

[0078] In some embodiments, the light-transmitting medium 20 is a medium with a condensation temperature lower than -20° C., thereby preventing the light-transmitting medium 20 from condensing and converting into a solid or liquid state, thereby improving the reliability of the lens 10 in different temperature environments.

[0079] Figure 3 is a circuit connection diagram of a lens assembly according to an exemplary embodiment.

[0080] In some embodiments, Figure 3 As shown, the lens assembly may further include a power supply 50, the positive pole of the power supply 50 may be connected to the first electrode 31, so that the first electrode 31 may serve as an anode, and the negative pole of the power supply 50 may be connected to the second electrode 32, so that the second electrode 32 may serve as a cathode.

[0081] If the power source 50 does not apply voltage to the first electrode 31 and the second electrode 32 , the light-transmitting medium 20 is evenly distributed in the lens 10 . At this time, when light passes through the lens 10 , the light path will not be twisted in the lens 10 .

[0082] When the power supply 50 applies voltage to the first electrode 31 and the second electrode 32, an electric field is generated between the cathode and the anode. When the electric field strength reaches a level that can excite and ionize the light-transmitting medium 20 in the middle as a gas phase medium, the gas phase medium will distribute its gas ionized molecules according to the direction of the electric field distribution strength. For example, the ionized molecules are densely distributed where the electric field strength is strong, and the molecules are sparsely distributed where the electric field strength is weak.

[0083] The specific distribution pattern can be determined by the polarity of the gas phase medium. The distribution of positive gas phase molecules is positively correlated with the electric field strength, while the distribution of negative gas phase molecules is negatively correlated with the electric field strength.

[0084] After the gas phase medium is ionized by the electrode, the density of the electric field distribution changes, so the overall performance is that the medium density in the lens 10 is different at different positions. When the light passes through the transparent medium, it will pass through areas with different densities. The density difference of the transparent medium 20 will distort the direction of light propagation, so that the lens 10 can gather a larger range of light, expand the field of view of the camera module, and enable the camera module to change the field of view as needed.

[0085] Figure 4 The figure is a schematic diagram of a control flow of a lens assembly according to an exemplary embodiment.

[0086] In some embodiments, Figure 4 As shown, the lens assembly may further include a control module, which may be a central processing unit or an integrated circuit. The control module may be connected to the first electrode 31 and the second electrode 32 respectively, and adjust the electrical signals input to the first electrode 31 and the second electrode 32.

[0087] The control module can be used to control the voltage value of the power supply 50 on the first electrode 31 and the second electrode 32 to achieve control of the field of view size. The control module can increase the electric field strength between the first electrode 31 and the second electrode 32 by causing the power supply 50 to output a larger voltage, thereby enhancing the trend of the distribution of ions in the light-transmitting medium 20 with the electric field strength, strengthening the optical path distortion of the incident light L, and increasing the influence of the lens 10 on the field of view.

[0088] The control module can also reduce the electric field strength of the first electrode 31 and the second electrode 32 by making the power supply 50 output a smaller voltage, thereby weakening the trend of the ions in the transparent medium 20 distributed along the electric field strength, weakening the optical path distortion of the incident light L, and reducing the influence of the lens 10 on the field of view.

[0089] In some embodiments, Figure 1 and Figure 4 As shown, the lens assembly may further include a photosensitive element 40, which may be connected to the control module. The photosensitive element 40 may transmit a light signal to the control module, and the control module may adjust the electrical signal input to the first electrode 31 and the second electrode 32 according to the received light signal.

[0090] Exemplarily, when the field of view size needs to be changed to the target field of view size, the photosensitive element 40 can receive the light signal irradiated to the photosensitive element 40 through the lens 10, and send the parameters of the light signal to the control module. The control module can analyze the parameter characteristics of the light signal and determine the current field of view size. Exemplarily, the control module can analyze the image distortion parameters of the optical image formed by the photosensitive element 40 and determine the current field of view size. The control module compares the current field of view size with the target field of view size and derives the direction of field of view change. When the field of view needs to be further increased, the control module can control the power supply 50 to output a higher voltage to the first electrode 31 and the second electrode 32, so that a stronger electric field is generated between the first electrode 31 and the second electrode 32, so that the density difference inside the light-transmitting medium 20 is further increased, so that the optical path distortion of the incident light L is enhanced, so that the lens 10 can gather a wider range of light, and expand the field of view of the camera module.
