The inner side (side facing the display panel 14) of the non-light-transmitting region 112 may be covered with black ink to be in a light-opaque state to cover the non-display region (such as a wiring region and a fitting region) of the outer periphery of the display region of the display panel 14. The lens 11 may have an electrical connection terminal. The electrical connection terminals may be electrically connected to the circuit board assembly 13 through, for example, wires of the display panel 14. Alternatively, the electrical connection terminals may be directly electrically connected to the circuit board assembly 13.

As shown in fig. 1-3, the functional units 112a in the lens 11 may be located in the opaque region 112, and there may be several functional units 112a, for example, these functional units 112a may be spaced apart. The specific shape of each functional body 112a may be designed according to actual needs, and is not limited to that shown in the drawings. The portion of the lens 11 other than the functional body 112a may be a substrate, the substrate may include a substrate 111b and a substrate 112b, the substrate 111b may be located in the light-transmitting region 111 (the substrate 111b may be fully covered with the light-transmitting region 111), and the substrate 112b may be located in a region other than the functional body 112a in the non-light-transmitting region 112. Fig. 1-3 depict the boundary of the functional body 112a with the substrate, which is merely a visual illustration.

For a single function 112 a: the surface of the functional body 112a facing the outside of the electronic device 10 may be exposed from the base and serve as the outer surface of the lens 11, or may be exposed from the base but covered with a conductive film (to be described later). The surface of the functional body 112a facing the inside of the electronic device 10 may be exposed from the base and serve as the inner surface of the lens 11, or may be exposed from the base and covered with a conductive film (to be described later).

In other embodiments, the number of functional bodies may be one, and the functional bodies may occupy only a partial area of the non-light-transmitting region 112, or may be distributed throughout the non-light-transmitting region 112. In other embodiments, the matrix may be distributed only in the light-transmitting region 111.

In the first embodiment, the conductivity of the substrate is poor (the substrate is an insulator), and the conductivity of the functional body 112a is good (the substrate is a conductor). The functional body 112a may be electrically connected to the circuit board assembly 13 through an electrical connection terminal of the lens 11 (wherein the functional body 112a may be electrically connected to the electrical connection terminal of the lens 11 through, for example, a conductive paste or a spring sheet, etc.), or may be electrically connected to the circuit board assembly 13 through a separate electrical connection site (for example, a conductive plating film).

In the first embodiment of the first embodiment, the electronic device 10 may include an electrocardiograph electrically connected to the circuit board assembly 13, and at least one of the plurality of functional bodies 112a may be electrically connected to the electrocardiograph to serve as an electrocardiographic detection electrode. When more than two functional bodies 112a are used as the electrocardiographic detection electrodes, the sampling area can be increased, which is beneficial to improving the detection precision of Electrocardiograph (ECG) signals. The area of the electrocardiograph detection electrode can be large enough to ensure good contact with the skin, and the detection accuracy of the ECG signal is improved. The electrocardiographic detection electrode is positioned in the non-light-transmitting area 112 on the front surface of the electronic device 10, and does not affect the screen display during detection, so that a user can watch the detection result while detecting.

In the first embodiment of the first embodiment, the surface of the functional body 112a, which is the electrocardiographic detection electrode, facing outward may be directly exposed for the user to touch. Alternatively, the outward facing surface of the functional body 112a may be formed with a conductive film, which may be formed by physical vapor deposition (physical vapor deposition, PVD) plating technique, for example, and which is exposed for user touch. The design of forming the conductive film on the outer surface of the functional body 112a facilitates increasing the detection area of the functional body 112a, and also facilitates manufacturing specific electrode surface patterns to accommodate different users' fingers. The inward facing surface of the functional body 112a as an electrocardiographic detection electrode may be exposed from the base and directly electrically connected to the electrocardiograph sensor, or the inward facing surface of the functional body 112a may be exposed from the base and covered with a conductive film through which the functional body 112a is electrically connected to the electrocardiograph sensor. The design of forming the conductive film on the inner surface of the functional body 112a facilitates increasing the electrical connection area of the functional body 112a to increase the electrical connection reliability.

As shown in fig. 4, in the first embodiment, the electronic device 10 may further include an electrocardiographic detection electrode 16 and an electrocardiographic detection electrode 17 provided in the housing 15, and the electrocardiographic detection electrode 16 and the electrocardiographic detection electrode 17 are electrically connected to the electrocardiograph. The electrocardiographic detection electrode 16 and the electrocardiographic detection electrode 17 may be metal electrodes, for example. The functional body 112a serves as an electrocardiographic detection electrode, and the electrocardiographic detection electrode 16 and the electrocardiographic detection electrode 17 cooperate to realize ECG signal detection.

In the first embodiment of the first embodiment, both the electrocardiographic detection electrode 16 and the electrocardiographic detection electrode 17 may be used to collect signals of one hand of the user wearing the electronic device 10, and the electrocardiographic detection electrode served by the functional body 112a may be used to collect signals of the other hand of the user not wearing the electronic device 10.

In one implementation of this embodiment, one of the electrocardiographic detection electrode 16 and the electrocardiographic detection electrode 17 may be referred to as a signal input electrode, for example, and the other may be referred to as a noise cancellation electrode, for example.

In another implementation of this embodiment, the electrocardiographic detection electrodes served by the at least two functional bodies 112a may include a signal input electrode and a noise cancellation electrode. The electrocardiographic detection electrode 16 and the electrocardiographic detection electrode 17 are externally presented as two detection electrodes to increase the detection area, but both may be combined into one detection electrode by the internal circuit of the electronic device 10. According to the product requirement, a detection electrode can be arranged on the external form to replace the split electrocardiograph detection electrode 16 and the electrocardiograph detection electrode 17.

According to the scheme of the first embodiment, the lens 11 is used as the screen cover plate of the electronic device 10, and the electrocardiograph detection electrode is arranged in the non-light-transmitting area 112 of the screen cover plate, so that the ECG signal detection can be realized by effectively utilizing the non-light-transmitting area 112, the utilization rate of the structural space of the electronic device 10 can be improved, the occupation of the extra structural space is reduced, the finger placement of a user can be conveniently carried out for detection, and the user experience is improved. In addition, by designing the lens 11 with good local conductivity, the lens 11 is used as a screen cover plate and an electrocardiograph detection electrode, so that functions of the lens are enriched, and the product competitiveness is improved.

In other implementations of the first embodiment, the lens used as the electrocardiographic detection electrode may be provided at other locations of the electronic device.

For example, referring to fig. 1 and 2, the lens may be located on a peripheral side of the electronic device 10. For example, the lens may be mounted to the peripheral side of the housing 12; or at least the peripheral portion of the housing 12 may be made of the material of the lens, i.e., the peripheral portion of the housing 12 is the lens. In this embodiment, the functional body on the peripheral side of the electronic device 10 may replace the functional body 112a described above, and the functional body cooperates with the electrocardiographic detection electrode 16 and the electrocardiographic detection electrode 17 to realize ECG signal detection. Alternatively, the functional body is provided on the peripheral side surface of the electronic device 10, and the functional body 112a is provided on the front surface of the electronic device 10, and the functional body, the functional body 112a, the electrocardiographic detection electrode 16, and the electrocardiographic detection electrode 17 on the peripheral side surface of the electronic device 10 cooperate to realize ECG signal detection.

Alternatively, as shown with reference to fig. 1 and 2, the lens may be located on the back of the electronic device 10. For example, the lens may be mounted on the housing 15, or at least a portion of the housing 15 may be made from the material of the lens, at least a portion of the housing 15 being the lens. In this embodiment, the functional body on the back of the electronic device 10 may replace the above-mentioned electrocardiographic detection electrode 16 and electrocardiographic detection electrode 17, and the functional body may cooperate with the above-mentioned functional body 112a (or may also cooperate with a functional body on the peripheral side of the electronic device 10) to implement ECG signal detection.

In other implementations of the first embodiment, the lenses provided at the respective positions of the electronic device 10 may be used to detect other physiological parameters besides ECG signals, such as electromyographic signals, bioelectric signals such as human body impedance, and the like. The signals collected by the functional bodies in the lens are processed by a corresponding processing unit (including a bioelectric sensor) in the electronic device 10, and the bioelectric signals can be detected. Wherein lenses in different positions may be used to detect a certain physiological parameter, respectively, so that the electronic device 10 may implement detection of multiple physiological parameters.

The second embodiment is that the function body in the lens has good heat conduction performance and is used for detecting the ambient temperature or the body temperature

Unlike the first embodiment, in other embodiments, the thermal conductivity of the functional body in the lens may be better. The functional body may be arranged close to a temperature sensor (e.g. a thermistor) within the electronic device, to which the functional body conducts heat, so that the electronic device may realize ambient temperature detection or body temperature detection. Wherein, at least a part of the surface of the functional body can be exposed from the matrix, thus being convenient for the functional body to fully collect heat; or the functional body can be completely enclosed by the matrix.

Third embodiment the functional body in the lens is a conductor, used as an antenna

Unlike the above embodiments, the lens in the electronic device may be an antenna. The following description will exemplify the lens 11.

Fig. 5 (a) shows a top view of the outer surface side of the lens 11, and fig. 5 (b) shows a top view of the inner surface side of the lens 11. As shown in fig. 5, the outer surface of the opaque region 112 of the lens 11 may be covered with an electrically conductive film 113, and the electrically conductive film 113 may be formed by PVD plating, for example. The pattern shape of the conductive film 113 may be designed as needed, and the circular ring shape around the circumference shown in fig. 5 is merely an illustration. For example, the conductive films 113 may be provided in a plurality of spaced apart positions, and the pattern shape of each conductive film 113 may be non-uniform. The conductive film 113 covers the functional body 112a and is connected to the functional body 112 a. One side surface of the functional body 112a facing away from the conductive film 113 may be exposed from the base body.

As shown in connection with fig. 5 and 2, the functional body 112a may be electrically connected to a feed in the circuit board assembly 13. Thus, the functional body 112a and the conductive film 113 can function as an antenna, thereby realizing a signal transmitting/receiving function. Providing the conductive film 113 on the outer surface of the lens 11 facilitates the formation of a specific conductive pattern, which facilitates the satisfaction of antenna requirements. In other embodiments, a conductive film may be provided on the inner surface of the lens 11, and the functional body 112a may be electrically connected to the feed source through the conductive film. The conductive film is provided on the inner surface of the lens 11, so that the electrical connection area of the functional body 112a can be increased, and the electrical connection reliability can be improved. Or in other embodiments, the inner and outer surfaces of the lens 11 may be devoid of conductive films.

Referring to fig. 2, the antenna may be spaced as far from the display panel 14 and the housing 12 as possible to reduce electromagnetic interference between the display panel 14 and the housing 12 (the housing 12 may be made of metal). For example, the antenna may be near a position where a distance from the display panel 14 in the thickness direction of the display panel 14 is largest.

As shown in fig. 5, the lens 11 may have a plurality of spaced apart functional bodies 112a thereon, which allows a plurality of antennas to be formed on the lens 11. The number of antennas may include at least one of a mobile communication antenna (e.g., 5G antenna, 4G antenna, 3G antenna, 2G antenna), wiFi antenna, bluetooth antenna, near field communication (near field communication, NFC) antenna, global positioning system (global positioning system, GPS) antenna, beidou antenna, etc.

According to the scheme of the embodiment, the lens 11 is used as the screen cover plate of the electronic device 10, and the antenna is arranged in the non-light-transmitting area 112 of the screen cover plate, so that the antenna function can be realized by effectively utilizing the non-light-transmitting area 112, the utilization rate of the structural space of the electronic device 10 can be improved, and the occupation of additional structural space can be reduced. In addition, by designing the lens 11 with good local conductivity, the lens 11 is used as a screen cover plate and an antenna, so that functions of the lens are enriched, and the product competitiveness is improved.

In other implementations of the third embodiment, the lens as the antenna may be provided at other locations of the electronic device, such as the peripheral side of the electronic device. The antennas at the other positions and the antennas on the screen cover plate can exist at the same time; or the antenna may be provided only at the other position, and the antenna is not provided on the screen cover plate.

Example IV functional body in lens has photovoltaic effect for photovoltaic Power Generation

Unlike the above embodiments, the lens in the electronic device may be used for photovoltaic power generation. The position of the lens may be the same as described above and will not be repeated here.

In this embodiment, the functional body of the lens may be manufactured from an optical fiber B having a photovoltaic effect. As shown in fig. 6, the optical fiber B may include a sheath B2 located at an outer layer and an inner core B1 located at an inner layer, the sheath B2 wrapping the inner core B1. The sheath B2 may also be referred to as a cladding, and the core B1 may also be referred to as a core. The material of the sheath B2 contains a conductive component, so that the sheath B2 has good conductive properties. The core B1 may be made of a photovoltaic material, such as monocrystalline silicon, polycrystalline silicon, amorphous silicon, etc., so that the core B1 has a photovoltaic effect. When the inner core B1 is irradiated by sunlight, an electric current is generated, and the electric current is transmitted to the skin layer B2.

In this embodiment, the skin layer B2 in the functional body may be electrically connected to a photovoltaic circuit in the electronic apparatus (the photovoltaic circuit may be disposed on a circuit board assembly in the electronic apparatus, for example) so that a current generated by the photovoltaic effect is transmitted to the photovoltaic circuit. The photovoltaic circuit may process the electrical signal including, but not limited to, voltage stabilization, storage (storage of electrical energy into a battery of the electronic device), and the like. Thus, the lens can realize photovoltaic power generation.

The key device of the traditional solar cell is a silicon crystal film with a photovoltaic effect, and a metal grid is generally printed on the silicon crystal film, and current is transmitted through the metal grid. Because the metal grid is of a planar structure, the conductive area is limited, and the transmitted current is smaller.

However, the optical fiber B of this embodiment uses the sheath layer B2 with the conductive function to replace the metal grid, and since the sheath layer B2 is a spatial three-dimensional structure and the metal grid is a planar structure, on the premise of a certain volume, the conductive area of the sheath layer B2 is larger than that of the metal grid, and the sheath layer B2 can guide more current into the photovoltaic circuit, thereby improving the photoelectric conversion efficiency.

In this embodiment, the lens may be provided in the electronic device in a position where it is easy to receive solar radiation. For example, referring to fig. 1, the lens may be used as a screen cover, and the functional body in the lens may be located in a non-light-transmitting region of the screen cover. Or, as shown with reference to fig. 1, the lens may be provided on a peripheral side of the electronic device, such as the lens may be mounted on a peripheral side of the housing 12; or at least the peripheral portion of the housing 12 may be made of the material of the lens, and the peripheral portion of the housing 12 is also the lens.

According to the scheme, through designing the lens with the photovoltaic effect, the electric energy storage can be realized by utilizing the lens, so that the functions of the lens are enriched, and the combination of photovoltaic power generation and conventional charging power storage schemes can be realized, so that the electric power endurance of the electronic equipment is improved, and the product competitiveness is improved. If the lens is used as a screen cover plate, the non-light-transmitting area can be effectively utilized to realize photovoltaic power generation, the utilization rate of the structural space of the electronic equipment is improved, and the occupation of additional structural space is reduced.

In other embodiments, all areas of the lens have a photovoltaic effect, i.e. the lens does not contain a matrix material, and the lens as a whole is manufactured from an optical fiber B having a photovoltaic effect.

Example five-lens with good light transmission properties for detecting physiological parameters

As shown in fig. 7, 8 and 9, the electronic device 20 of the fifth embodiment may be, for example, a smart watch. The electronic device 20 may include a display 21, a housing 23, keys 22, and a detection module 24.

The housing 23 may be, for example, an assembly formed by assembling a plurality of single housings, and the housing 23 encloses an installation space 23a having an opening. The case 23 is provided with a key hole 23b, the key hole 23b penetrating the case 23, and the key hole 23b may be provided on a side surface of the case 23, for example. The display screen 21 (which may include a screen cover and a display panel laminated and bonded) is mounted to the housing 23, and may cover an opening of the mounting space 23a.

The detection module 24 may be located in the installation space 23 a. The detection module 24 has electrical connection terminals 241, which electrical connection terminals 241 may include, for example, a flexible circuit board and connectors disposed thereon. The electrical connection terminals 241 may be electrically connected to a circuit board assembly (not shown) within the mounting space 23a to enable the operation of the detection module 24. The detection module 24 may be an optical sensor that functions as a physiological parameter detection including, but not limited to, heart rate detection, blood glucose detection, finger vein detection, fingerprint detection, etc.

The key 22 may be fitted into the key hole 23b, one end of the key 22 may be exposed to the outside of the housing 23, and the other end of the key 22 may be located in the installation space 23 a. The key 22 is movable, for example, along the axis of the key hole 23b and rotatable about the axis of the key hole 23b, such a key 22 may also be referred to as a crown. Alternatively, the keys 22 may be movable in a direction parallel to the outer surface of the housing 23, such keys 22 may serve as other functional keys, such as volume keys, power keys, etc.

As shown in fig. 10, 11 and 12, the key 22 may include a key case 222, a lens 223 and a stopper 221.

As shown in fig. 11 and 12, the key case 222 may have a substantially cylindrical structure with both ends open. The key case 222 may include a first case portion 222a and a second case portion 222b connected to each other, and the first case portion 222a and the second case portion 222b may each have a cylindrical structure. The diameter of the first housing portion 222a may be smaller than the diameter of the second housing portion 222 b. Along the centerline of the key case 222, the projection of the first housing portion 222a may fall within the boundaries of the second housing portion 222 b. The key case 222 may be made of a non-light conductive material, including but not limited to a metallic material. In other embodiments, the structure of the key case may be designed according to need, and is not limited to the above.

As shown in fig. 11 and 12, the lens 223 may include a first lens portion 223a and a second lens portion 223b, the first lens portion 223a may be a cylindrical structure, and the second lens portion 223b may be a generally truncated cone structure having a smaller diameter end connected to the first lens portion 223a, and a smaller end of the truncated cone structure may have a diameter substantially corresponding to the diameter of the first lens portion 223 a.

In this embodiment, the lens 223 may be made of optical fibers, so that the lens 223 has good light transmission performance. In other embodiments, the lens 223 may be made of other materials that are highly optically conductive.

As shown in fig. 10-12, the lens 223 may be received and secured within the key case 222. Wherein the first lens portion 223a may be located within the first housing portion 222a, the first lens portion 223a may be mated with the first housing portion 222a, and a surface of the first lens portion 223a facing away from the second lens portion 223b may be exposed from an opening of the first housing portion 222 a. The second lens portion 223b may be located within the second housing portion 222b, the second lens portion 223b may be mated with the second housing portion 222b, and a surface of the second lens portion 223b facing away from the first lens portion 223a may be exposed from an opening of the second housing portion 222 b.

As shown in fig. 11, the stopper 221 may be, for example, a semi-ring structure with a notch. The limiting member 221 may be, for example, a snap spring. As shown in fig. 10 to 12, the stopper 221 is adapted to be mounted on the outer periphery of the first housing portion 222a of the key housing 222 to function as a stopper for the key housing 222 (to be described later).

Fig. 13 is a top view of the structure shown in fig. 8, and fig. 14 is a partially enlarged schematic view of the structure at B in fig. 13. As shown in fig. 14, after the key 22 is mounted to the housing 23, the second housing portion 222b of the key housing 222 may be exposed outside the housing 23, the first housing portion 222a of the key housing 222 may be engaged with the key hole 23b, and an end of the first housing portion 222a facing away from the second housing portion 222b may be located in the mounting space 23a of the housing 23. The limiting piece 221 can be abutted against the inner wall of the casing 23, so as to prevent the key casing 222 from falling off from the casing 23.

As shown in fig. 14, the first lens portion 223a may be opposite the detection module 24, and the specific position and size of the two may be set as desired.

When it is desired to detect a physiological parameter, a user's finger may be placed at the end face of the second lens portion 223 b. At this time, the detection module 24 may emit invisible light, which may enter the lens 223 from the first lens portion 223a, exit from the second lens portion 223b, and then enter the finger skin. The finger can reflect, refract, scatter and the like the incident light, and the light signal processed by the finger is folded back, and the folded back light signal can be called an external light signal. The external optical signal is transmitted to the detection module 24 through the lens 223. After the external optical signal collected by the detection module 24 is processed, the electronic device 20 can detect physiological parameters, such as heart rate, blood sugar, finger veins, fingerprints, and the like.

The scheme of the embodiment uses the lens 223 made of the optical fiber to transmit light, and the optical signal can be transmitted from the input surface to the output surface of the optical fiber with high fidelity due to the large beam value, strong light collecting capability and high resolution of the optical fiber, so that the optical signal acquisition precision of the detection module 24 is ensured, and the detection precision of the physiological parameter is ensured. And, by making the second lens portion 223b into a truncated cone shape, the area of the second lens portion 223b for placing the finger is larger, so that the light can irradiate more human body area, and more external light signals can be collected, thereby enhancing the physiological parameter detection precision. When an external light signal is transmitted in the second lens portion 223b, the second lens portion 223b can concentrate the external light signal so that it can be transmitted in the first lens portion 223a with limited space.

From the above analysis, it can be seen that the lens is formed with a flared structure (e.g., a truncated cone structure) at the end thereof remote from the detection module 24, which can guide the light signal emitted from the detection module 24 along the divergent path. Thus, in other embodiments, the lens is not limited to the structural form of the lens 223 described above. For example, the lens as a whole may be of a truncated cone configuration, without a cylindrical portion. Alternatively, the lens may include a first lens portion (corresponding to the first lens portion 223 a) and a second lens portion (corresponding to the second lens portion 223 b), with the projection of the first lens portion falling within the boundary of the second lens portion along the optical axis direction of the lens (the direction perpendicular to the light exit surface of the detection module 24). The first lens portion and the second lens portion can each have any suitable configuration, e.g., the second lens portion can have a generally racetrack, cylindrical, rounded rectangular configuration, etc., and the second lens portion can have a generally racetrack, cylindrical, etc., configuration, depending on the product requirements.

In the present embodiment, since the assembling reliability of the first housing portion 222a and the key hole 23b is good (cylindrical structure fitting circular hole), by making the first lens portion 223a cylindrical, the first lens portion 223a can be fitted with the first housing portion 222a, thereby enhancing the assembling reliability of the lens 223 and the key case 222.

According to the scheme, the optical signals are transmitted through the optical fiber lens to achieve physiological parameter detection, so that functions and application scenes of the lens are enriched. By integrating the optical fiber lens in the key 22, the key space can be effectively utilized to realize the physiological parameter detection function, the structural space utilization rate of the electronic equipment is improved, the occupation of additional structural space is reduced, and the product competitiveness is improved.

Example six-lens with specific microstructure exhibiting set texture effect

As shown in fig. 15, the electronic device 30 of the sixth embodiment may be, for example, a smart watch. The electronic device 30 comprises a lens 31, which lens 31 may be, for example, a screen cover for attaching to a display panel. The lens 31 may be made of, for example, optical fibers, the lens 31 comprising a plurality of optical fibers fused together.

In one embodiment, the outer surface (the surface facing the user) and/or the inner surface (the surface facing away from the outer surface) of the lens 31 may be provided with a plurality of micro-holes, the number of micro-holes may be determined as desired, the aperture of the micro-holes may be small, and the array of micro-holes may not be visible to the naked eye. The micropores may be arranged according to a set rule. Illustratively, the micro-holes can be machined on the lens 31 by using laser, and the laser perforation process can ensure the forming precision of the micro-holes and has good mass production.

When the electronic device 30 is off-screen, the array of micro-holes reflects ambient light (including sunlight and light from other light sources) to form a texture pattern, such as a character, character or scene image, logo, motif, etc. (the shaded texture pattern in fig. 15 is merely one illustration). The depth of the micropores of each region may be substantially uniform such that the texture pattern formed is substantially a planar texture pattern. Alternatively, the depth of the micropores of each region may not be the same so that the formed texture pattern may have a stereoscopic relief effect.

In this embodiment, at least a part of the inner walls of the micropores may have an optical material layer for performing a treatment such as reflection and/or absorption of ambient light. The reflectivity of the optical material layer may not be the same for each region. The reflection of ambient light is enhanced in the area with high reflectivity, so that the brightness of the texture pattern formed by the area is high; the area of low reflectivity has reduced reflection of ambient light and therefore the area forms a texture pattern of less brightness. The optical material layer may also be used to absorb harmful light (e.g., blue-violet light) emitted by the display panel to reduce the damage of the screen to the eyes. Illustratively, the layer of optical material may be formed by an electroplating process. It will be appreciated that a layer of optical material is not required.

When the electronic device 30 is on, the lens 31 with micropores can transmit light normally, and the display effect is not affected, because the lens 31 is made of optical fibers with good light guiding performance. In addition, the lens 31 can also be internally provided with a touch trace, and the touch performance is not affected by the provision of micropores through reasonable practice.

In another embodiment, instead of the micro-hole arrangement described above, the optical fibers of different lengths may be fused together during the manufacture of the lens 31 to form a micro-hole array-like structure. By arranging the long and short fibers according to a certain rule, the lens 31 can also form a texture pattern when reflecting ambient light. In addition, the lens 31 of the present embodiment does not affect the normal display and touch functions.

In another embodiment, unlike the above-described micro-hole-forming scheme, the optical fibers in the lens 31 are not all the same in reflectivity, and one portion of the optical fibers has a higher reflectivity and the other portion has a lower reflectivity. The optical fibers with different reflectivities can be arranged according to a set rule. The transmittance of all the fibers in the lens 31 may be uniform. When the electronic device 30 is off the screen, the areas with high reflectivity have larger brightness and the areas with low reflectivity have smaller brightness, so that the different areas of the lens 31 form light and shade changes, thereby forming a texture pattern. The lens 31 of the present embodiment does not affect the normal display and touch functions.

Alternatively, in another embodiment, the optical fibers in some areas of the lens 31 may be broken, such that a single fiber is broken into at least two portions, wherein at least a portion of the cross-section may be curved, such as convex or concave. That is, the lens 31 includes a first optical fiber including a broken first portion and a broken second portion, and at least one of a cross section of the first portion and a cross section of the second portion (the two cross sections are disposed opposite to each other) is a curved surface. The positions at which the cross sections are formed may be arranged according to a certain rule. Illustratively, the breaking process may be accomplished using a laser engraving process.

When the electronic device 30 is off-screen, the area with the section will form a textured pattern due to the reflection of ambient light by the section. If the surface of the lens 31 includes a cambered surface region, the three-dimensional effect of the texture pattern is stronger. The lens 31 of the present embodiment does not affect the normal display and touch functions.

According to the product requirement, the solutions of the above embodiments of the present embodiment may be combined, so that the lens 31 presents a texture pattern when the electronic device 30 is off the screen, and the display and touch functions are not affected when the electronic device 30 is on the screen.

In the solution of the present embodiment, the lens 31 with a special microstructure is designed, so that the lens 31 can reflect ambient light to present a set texture pattern, thereby enriching the functions of the lens. By using the lens 31 as a screen cover plate, the front surface of the electronic device can be effectively utilized to display texture patterns, so that the user experience of the product is enhanced, and the competitiveness of the product is improved.

In other embodiments, lenses capable of reflecting ambient light and exhibiting a textured pattern may also be provided at other locations of the electronic device, such as the peripheral side of the electronic device. For example, the lens may be mounted to a peripheral side of a center of the electronic device, or the lens may be mounted to a key of the electronic device. Alternatively, a lens capable of reflecting ambient light and exhibiting a textured pattern may also be used in devices that do not require electrical actuation, such as mechanical watches, wall clocks, etc., where the lens may be, for example, a glass panel of a mechanical watch or wall clock.

In the embodiment of the application, the lens in the electronic equipment can have at least one of the functions according to the product requirement.

The foregoing is merely illustrative of the present application, and the present application is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
