Background technique

For electronic devices, such as mobile phones, ambient light sensors are provided to detect ambient light; when the mobile phone is used in environments with different brightness, the ambient light sensor adjusts the brightness of the mobile phone screen according to the brightness of the external ambient light; when the ambient light sensor detects that the external brightness is high, the mobile phone increases the brightness of the screen, and when the ambient light sensor detects that the external brightness is low, the mobile phone reduces the brightness of the screen so that the user can see the screen more clearly. In addition, the ambient light sensor can also be used to assist the mobile phone in taking pictures. The ambient light sensor is generally set in the black border area outside the screen; however, as the screen ratio becomes larger and larger, and the black border area becomes smaller and smaller, it is no longer a market advantage to continue to retain the black border area for the ambient light sensor.

Summary of the invention

The present application provides an optical component and an electronic device to solve the problem that the screen ratio is getting larger and larger, the black border area is getting smaller and smaller, which is not conducive to the installation of an ambient light sensor.

The technical solution is as follows:

In a first aspect, the present application provides an optical component, wherein the optical component is used to be arranged below a display screen of an electronic device;

The optical assembly includes a light-guiding structure, a functional module and a light-shielding member;

The light guide structure has a first side surface and a second side surface opposite to each other, and the light guide structure is used to transmit the light emitted by the functional module or/and the light received by the functional module. The first side surface has a light-transmitting area, and the light-transmitting area is used to allow the light emitted by the functional module or/and the light received by the functional module to pass through. The light received by the functional module is the external light that passes through the display screen and the light guide structure in sequence and is emitted to the functional module.

The functional module is located at the side where the second side surface of the light guide structure is located, and the functional module includes a first sub-component and a second sub-component, and the first sub-component and the second sub-component are arranged side by side;

The light shielding member is arranged between the display screen and the light guiding structure.

By adopting the above-mentioned scheme, after the optical component is set under the display screen, the first sub-device and the second sub-device share a light-guiding structure, so that external light can be transmitted to the functional module through the light-guiding structure, or a sub-device in the functional module emits light and is emitted from the light-guiding structure, so that different sub-devices of the functional module can share the light-emitting area on the display screen, and the shading member can weaken or eliminate the impact of the light emitted by the functional module on the display screen, or the impact of the display screen on the functional module; and in actual application, when the first sub-device is a soft light and the second sub-device is an ambient light sensor, the same opening area on the display screen can be shared, which is conducive to transferring the position of the ambient light sensor from the black border area to other positions of the screen, so as to increase the screen-to-body ratio of the display screen by reducing the black border area on the periphery of the display screen.

In some implementations, the light shielding member is in contact with the first side surface, the light shielding member has a light through hole, and the light through hole corresponds to the light-transmitting area.

By adopting the above solution, the light through the light-shielding member is allowed to propagate, thereby reducing or eliminating the influence of the light emitted by the functional module on the display screen, or the influence of the display screen on the functional module.

In some implementations, the shading element is made of a deformable material.

By adopting the above solution, after the display screen and the light guide structure are installed, the deformation of the shielding member is beneficial to improving the sealing of the connection, thereby reducing the possibility of light leakage.

In some implementations, the deformable material is light-shielding foam.

By adopting the above scheme, the shading foam has the characteristics of shading, and is elastic and can be deformed; after it is installed between the display screen and the light-guiding structure, it not only achieves the effect of shading, but also has a shock-absorbing effect due to its elasticity, avoiding hard contact between the light-guiding structure and the display screen, thereby protecting the display screen and the light-guiding structure.

The center of the light-transmitting area, the center of the Fresnel fringe, and the center of the first sub-component are coaxially arranged;

By adopting the above scheme, Fresnel patterns are designed in the texture area to achieve the focusing effect; and the center of the light-transmitting area, the center of the Fresnel patterns and the center of the first sub-device are coaxially arranged, so that the effect of the Fresnel patterns can be maximized; because the center of the non-texture area and the light-transmitting area are offset in the thickness direction of the light-guiding structure, the second sub-device is arranged opposite to the non-texture area, so that more light entering from the light-transmitting area can reach the second sub-device.

In some implementations, the light guide structure includes a protruding portion, a supporting portion, and a main body portion, and from the first side surface to the second side surface, the protruding portion, the supporting portion, and the main body portion are connected in sequence;

The light-transmitting area is located on the protruding portion, the protruding portion protrudes in the direction where the display screen is located, and the supporting portion is used to be connected to the housing of the electronic device;

The main body has a first peripheral surface and a first light-transmitting surface, and the textured area and the non-textured area are located on the first light-transmitting surface.

By adopting the above solution, the protrusion is conducive to reducing the distance between the light-transmitting area and the display screen, thereby reducing the light path propagation distance, thereby reducing the energy loss of light, and can better reduce light leakage. The support part is convenient to be installed on the housing of the electronic device; the main body side is convenient for light transmission.

In some implementations, the first light-transmitting surface includes a first sub-surface and a second sub-surface, a step structure is formed between the first sub-surface and the second sub-surface, and along the thickness direction of the light-guiding structure, the distance between the first sub-surface and the first sub-device is smaller than the distance between the second sub-surface and the first sub-device; the first sub-surface is opposite to the first sub-device, and the second sub-surface is opposite to the second sub-device.

By adopting the above solution, a height difference is formed between the first sub-surface and the second sub-surface by utilizing the step structure, so as to adapt to the height of the first sub-component and the second sub-component respectively.

In some implementations, the textured area is located on the first sub-surface, and the non-textured area is located on the second sub-surface.

By adopting the above solution, the functions of the first sub-device and the second sub-device are adapted respectively.

In some implementations, the first peripheral surface has a light-shielding layer.

By adopting the above solution, it is possible to prevent light from being transmitted through the first peripheral surface, thereby reducing light energy loss.

In some implementations, the protrusion has a second peripheral surface and a first surface, the light-transmitting area is located on the first surface; the second peripheral surface is a non-light-transmitting area; and the first side surface includes the first surface.

By adopting the above solution, light only passes through the light-transmitting area, thereby reducing light energy loss.

In some implementations, the support portion has a third sub-surface and a fourth sub-surface relative to each other, and the third sub-surface and the fourth sub-surface are non-light-transmitting areas; the support portion also has a third peripheral surface connecting the third sub-surface and the fourth sub-surface, and the third peripheral surface is a non-light-transmitting area; the first side surface includes the third sub-surface; and the second side surface includes the fourth sub-surface.

By adopting the above solution, light only passes through the light-transmitting area, thereby reducing light energy loss.

In some implementations, the first sub-device is a soft light, an ambient light sensor, a color temperature sensor, a laser focus sensor, or a distance sensor;

The second sub-device is an ambient light sensor, a color temperature sensor, a laser focus sensor, a distance sensor or a soft light.

In some implementations, the first sub-component is a soft light; the second sub-component is an ambient light sensor;

The ambient light sensor is used to detect the current external ambient light before the soft light is turned on to obtain a first ambient light brightness value;

Wherein, when the soft light is in the on state, the brightness value of the display screen of the electronic device is determined according to the first ambient light brightness value and a preset ambient light brightness compensation value.

By adopting the above solution, the soft light and the ambient light sensor do not work at the same time, thereby avoiding the influence of the soft light on the ambient light sensor.

In some implementations, a light path changing structure is provided in the light guiding structure, and the light path changing structure is configured to reflect external light entering the light guiding structure through the light-transmitting area to the second sub-device.

By adopting the above solution, more light from the outside can be transmitted to the second sub-device through the optical path changing structure. Of course, when the second sub-device is a light-emitting device, more light will also be transmitted to the outside through the optical path changing structure.

In some implementations, the optical path changing structure includes a first reflecting surface and a second reflecting surface, the first reflecting surface is used to reflect the external light entering the light guiding structure through the light-transmitting area to the second reflecting surface, and the second reflecting surface is used to reflect the external light reflected by the first reflecting surface to the second sub-device.

By adopting the above solution, the first reflection surface and the second reflection surface arranged in the light guide structure can better realize the change in light, and because the first reflection surface and the second reflection surface are arranged in the light guide structure, this is conducive to reducing the space occupied by the entire optical component.

A second aspect of the present application provides an electronic device, comprising a display screen and an optical component as described in any one of the above; the display screen comprises a display layer, the display layer has a first opening, and the light-transmitting area corresponds to the first opening.

By adopting the above solution, when the first sub-device is a soft light and the second sub-device is an ambient light sensor, the first opening on the display screen can be shared, thereby facilitating the transfer of the position of the ambient light sensor from the black border area to other positions of the screen, so as to increase the screen-to-body ratio of the display screen by reducing the black border area on the periphery of the display screen.

In some implementations, the electronic device also includes a camera, a second opening is opened on the display layer, the second opening is arranged side by side with the first opening, the first opening and the second opening are located on the top of the display screen; the camera is arranged corresponding to the second opening.

In the description of this application, unless otherwise specified, "/" means or, for example, A/B can mean A or B; "and/or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not limit them to be different.

In the related art, as shown in FIG1 , the ambient light sensor 11 is generally arranged in the black border area 10 on the periphery of the screen of an electronic device, such as a mobile phone; however, as the screen ratio becomes larger and larger, and the black border area becomes smaller and smaller, it is no longer advantageous to keep the black border area for the ambient light sensor 11. In some OLED screens (Organic Light-Emitting Diode, Chinese: Organic Light Emitting Diode), the ambient light sensor is the way of under-screen ambient light, and a hole is opened on the display layer of the screen, and the light transmittance of the OLED screen cover is used to realize the under-screen ambient light function. In addition, in the context of users' increasingly high requirements for the quality of mobile phone photography, a solution of setting a front soft light has emerged to enhance the user's front-facing photography experience; as shown in FIG2 , some soft lights 12 are also arranged in the black border area 10 on the periphery of the screen, and when the black border area 10 becomes smaller and smaller, it is no longer advantageous to set the soft light in the black border area; in the case of both the soft light 12 and the ambient light sensor 11, the two devices are arranged in different positions, which occupies a large space, and due to the existence of the black border area 10, it is not conducive to improving the screen ratio. To this end, the present application provides an optical component and an electronic device to solve the above problems.

The optical component and the electronic device 100 provided in the embodiments of the present application are explained in detail below.

In combination with Figures 3, 4 and 7, the first aspect of the present application provides an optical component, which is used to be arranged below the display screen 101 of the electronic device 100, and the optical component includes a light-guiding structure 201, a functional module 202 and a shading member 203; the light-guiding structure 201 has a first side surface 204 and a second side surface 205 opposite to each other, the light-guiding structure 201 is used to transmit the light emitted or/and the light received by the functional module 202, the first side surface 204 has a light-transmitting area 206, the light-transmitting area 206 is used to allow the light emitted and received by the functional module 202 to pass through, the light received by the functional module 202 is the external light that passes through the display screen 101 and the light-guiding structure 201 in sequence and is emitted to the functional module 202; the functional module 202 is located on the side where the second side surface 205 of the light-guiding structure 201 is located, the functional module 202 includes a first sub-device 207 and a second sub-device 208, the first sub-device 207 and the second sub-device 208 are arranged side by side; the shading member 203 is arranged between the display screen 101 and the light-guiding structure 201.

At least one embodiment of the present application provides an optical assembly, after the optical assembly is set under the display screen 101, so that the first sub-device 207 and the second sub-device 208 share a light-guiding structure 201, so that external light can be transmitted to the functional module 202 through the light-guiding structure 201, or a sub-device in the functional module 202 emits light and is emitted from the light-guiding structure 201, so that different sub-devices of the functional module 202 can share the light-emitting area on the display screen 101. When the functional module 202 emits light, if the light shielding member 203 is not set, the light may enter the display screen 101, so that a local bright spot problem will appear on the display screen 101. In addition, when the display screen 101 emits light, the light generated by the display screen 101 may also be received by the functional module 202 through the light-guiding structure 201, interfering with the normal operation of the functional module 202. Therefore, in the embodiment of the present application, the light shielding member 203 is set to reduce or eliminate the influence of the light emitted by the functional module 202 on the display screen 101, or the influence of the display screen 101 on the functional module 202. In addition, the light shielding member 203 can also ensure that the camera 106 is not affected by the functional module The light emitted by block 202 is affected; in actual application, after the optical component is arranged under the display screen 101, when the first sub-device 207 is a soft light and the second sub-device 208 is an ambient light sensor, the same opening area on the display screen 101 can be shared, thereby facilitating the transfer of the position of the ambient light sensor from the black border area to other positions of the screen, so as to increase the screen-to-body ratio of the display screen 101 by reducing the black border area on the periphery of the display screen 101, wherein the screen-to-body ratio is the ratio of the area of the display area in the display screen 101 to the projection area of the cover plate of the display screen 101, and the larger the screen-to-body ratio, the better the effect of the electronic device 100 in displaying images.

In some embodiments, the shading member 203 guides the light propagating between the outside world and the light-guiding structure 201, thereby preventing the light generated by the display screen 101 itself from affecting the light-guiding structure 201, or preventing the light emitted by the functional module from affecting the light generated by the display screen 101 itself after being emitted from the light-transmitting area 206.

As shown in Figures 3 and 4, the display screen 101 of the electronic device 100 is located on the side where the first side 204 of the light guide structure 201 is located, and the shading member 203 is located on the side where the first side 204 of the light guide structure 201 is located; in this way, the functional module and the display screen 101 are respectively located on the opposite sides of the light guide structure 201, thereby realizing the transmission of light between the outside world and the functional module assembly. After the outside light enters the light guide structure 201 through the display screen 101 and is emitted from the light guide structure 201, it is directly transmitted to the functional module 202 for reception, and the light emitted by the functional module 202 directly enters the light guide structure 201 and is then emitted to the outside world through the display screen 101.

In some embodiments, the first sub-device 207 and the second sub-device 208 are close to each other, that is, the distance between the two sub-devices is relatively short, so that they can share the same opening area.

As shown in FIG. 4 and FIG. 7 , in some embodiments, the shading member 203 contacts the first side surface 204, and the shading member 203 has a light hole 209, and the light hole 209 corresponds to the light-transmitting area 206. In this way, the light passing through the light hole 209 can reduce or eliminate the influence of the light emitted by the functional module 202 on the display screen 101, or the influence of the display screen 101 on the functional module 202. In one embodiment, the shading member 203 can be an annular structure, and the light hole 209 can be a circular hole or a hole of other shapes, such as a polygonal hole, that is, a hole with a polygonal outline, such as a quadrilateral, hexagon or octagon; the light-transmitting area 206 can be circular, which is conducive to the light hole 209 and The light-transmitting area 206 are adapted; one side of the shading member 203 contacts the display screen 101, and the other side of the shading member 203 opposite to the first side surface 204 contacts; and the shading member 203 can be directly arranged between the display screen 101 and the light-guiding structure 201 by interference fit.

It should be noted that, in some other possible implementations, in order to facilitate installation and stability after installation, at least one of the two opposite side surfaces of the shading member 203 has an adhesive backing, which facilitates installation. For example, the shading member 203 is bonded to the display screen 101 via the adhesive backing; of course, the shading member 203 can also be bonded to the light-guiding structure 201 via the adhesive backing.

In some embodiments, the material of the shading member 203 is a deformable material, so that after the display screen 101 and the light guide structure 201 are installed, the deformation of the shading member is conducive to improving the sealing of the connection, thereby reducing the possibility of light leakage. In one embodiment, the deformable material is an elastic material, so the use of an elastic material can ensure that the shading member 203 is not easy to shake between the display screen 101 and the light guide structure 201.

In some embodiments, the deformable material is light-shielding foam. The light-shielding foam has the characteristics of light shielding, elasticity, and deformation; after being installed between the display screen 101 and the light guide structure 201, it not only achieves the effect of light shielding, but also has a shock-absorbing effect due to its elasticity, avoiding hard contact between the light guide structure 201 and the display screen 101, thereby protecting the display screen 101 and the light guide structure 201.

It should be noted that, in some other embodiments, the hole wall of the light hole 209 may have a light-shielding coating, such as ink, which can have a good light-proof effect and ensure that light can only enter and exit from the hole of the light hole 209. In addition, the deformable material is not limited to light-shielding foam, and other elastic materials, such as silicone, can also be used.

As shown in FIG. 4 and FIG. 7 , in some embodiments, the second side surface 205 has a textured area for light transmission and a non-textured area for light transmission, and the textured area has a Fresnel pattern 210; the center of the light-transmitting area 206 and the center of the Fresnel pattern 210 are coaxially arranged with the center of the first sub-component 207; the second sub-component 208 is arranged opposite to the non-textured area; the Fresnel pattern 210 is mainly composed of a plurality of concentric circular grooves from small to large, and the cross section of the Fresnel pattern 210 is sawtooth-shaped. In this way, the Fresnel pattern 210 is designed in the textured area to achieve the effect of focusing; and the center of the light-transmitting area 206 and the center of the Fresnel pattern 210 are coaxially arranged with the center of the first sub-component 207, so that the effect of the Fresnel pattern 210 can be maximized; because in the thickness direction of the light-guiding structure 201, the non-textured area is offset from the center of the light-transmitting area 206, so the second sub-component 208 is arranged opposite to the non-textured area, so that the light entering from the light-transmitting area 206 can reach the second sub-component 208 more. In one embodiment, when the light-transmitting area 206 is circular, the center of the light-transmitting area 206 is the center of the circle, when the first sub-component 207 is a soft light lamp, the center of the first sub-component 207 is the center of the light-emitting area of the soft light lamp, and when the first sub-component 207 is a soft light lamp, the center of the light-transmitting area 206 and the center of the Fresnel fringe 210 are coaxially arranged with the center of the first sub-component 207, so that more light emitted by the soft light lamp can be transmitted from the light-transmitting area 206. When the first sub-component 207 is a sensor, the center of the first sub-component 207 is the center of the photosensitive area of the sensor. It should be noted that the Fresnel fringe 210 is not shown in FIG. 6, and the structure of the Fresnel fringe 210 can refer to FIG. 9.

As shown in FIG. 4 and FIG. 7 , in some embodiments, the light guide structure 201 includes a protruding portion 211, a supporting portion 212 and a main body 213. From the first side surface 204 to the second side surface 205, the protruding portion 211, the supporting portion 212 and the main body 213 are connected in sequence; the light-transmitting area 206 is located on the protruding portion 211, the protruding portion 211 protrudes in the direction where the display screen 101 is located, and the supporting portion 212 is used to connect with the housing 105 of the electronic device 100; the main body 213 has a first peripheral surface 214 and a first light-transmitting surface 215, and the texture area and the non-texture area are located on the first light-transmitting surface 215. In this way, the protruding portion 211 is conducive to reducing the distance between the light-transmitting area 206 and the display screen 101, thereby helping to reduce the light path propagation distance, thereby reducing the energy loss of light, and can better reduce the light leakage phenomenon. The supporting portion 212 is convenient to be installed on the housing 105 of the electronic device 100; the main body 213 side is convenient for light transmission. In one embodiment, the thickness direction of the light guide structure 201 is perpendicular to the surface of the display screen 101, and the direction from the first side surface 204 to the second side surface 205 is parallel to the thickness direction of the light guide structure 201; in the thickness direction of the light guide structure 201, the cross-section of the protrusion 211 is circular, and the cross-section of the protrusion 211 is perpendicular to the thickness direction of the light guide structure 201; as shown in Figures 5 and 8, the protrusion 211 has a second peripheral surface 216 and a first surface 217, the light-transmitting area 206 is located on the first surface 217, and the light-transmitting area 206 is a plane; the other areas of the first surface 217 are non-light-transmitting areas, and the non-light-transmitting areas of the first surface 217 can be achieved by a shading layer; the second peripheral surface 216 has a shading layer, which prevents light from leaking from the second peripheral surface 216. In combination with FIG. 5 and FIG. 6, and FIG. 8 and FIG. 9, the support portion 212 has a third sub-surface 218 and a fourth sub-surface 219 opposite to each other, the third sub-surface 218 faces the display screen 101, the fourth sub-surface 219 faces away from the display screen 101, and the fourth sub-surface 219 is connected to the housing 105 of the electronic device 100. Exemplarily, the fourth sub-surface 219 is connected to the housing 105 by bonding, for example, by using adhesive to fix the housing 105. The protrusion 211, the support portion 212 and the main body 213 are an integral structure. The material of the light guide structure 201 can be glass or resin, and the use of resin is conducive to reducing the weight of the light guide structure 201. The support portion 212 also has a third circumferential surface 220, a third sub-surface 218 and a fourth sub-surface 219, and the non-light-transmitting area can be shielded by a light-shielding layer; the third circumferential surface 220 is a non-light-transmitting area, and a light-shielding layer is set on the third circumferential surface 220 to prevent light from leaking from the third circumferential surface 220, that is, in the outer surface of the light-guiding structure 201, the light-transmitting part includes the light-transmitting area 206, the texture area and the non-texture area, and the rest of the light-guiding structure 201 is a non-light-transmitting surface. The first side surface 204 includes a first surface 217 and a third sub-surface 218; the second side surface 205 includes a first light-transmitting surface 215 and a fourth sub-surface 219.

As shown in combination with FIG. 6 and FIG. 9 , in some embodiments, the first light-transmitting surface 215 includes a first sub-surface 221 and a second sub-surface 222, and a step structure is formed between the first sub-surface 221 and the second sub-surface 222. In the thickness direction of the light-guiding structure 201, the distance between the first sub-surface 221 and the first sub-component 207 is smaller than the distance between the second sub-surface 222 and the first sub-component 207; the first sub-surface 221 is opposite to the first sub-component 207, and the second sub-surface 222 is opposite to the second sub-component 208. In this way, a height difference is formed between the first sub-surface 221 and the second sub-surface 222 by using the step structure to adapt to the height of the first sub-component 207 and the second sub-component 208 respectively. Specifically, in the thickness direction of the light-guiding structure 201, the first sub-surface 221 and the second sub-surface 222 have a height difference, thereby forming a step structure, and the first sub-surface 221 and the second sub-surface 222 are connected by a step surface 223, and the step surface 223 can be a non-light-transmitting area, that is, the step surface 223 also has a light-shielding layer.

In some embodiments, the textured area is located on the first sub-surface 221 and the non-textured area is located on the second sub-surface 222, so as to respectively adapt the functions of the first sub-device 207 and the second sub-device 208; the non-textured area is a plane.

In some embodiments, the first peripheral surface 214 has a light shielding layer, which can prevent light from penetrating from the first peripheral surface 214, thereby reducing light energy loss.

In some embodiments, the first sub-device 207 is a soft light, an ambient light sensor, a color temperature sensor, a laser focus sensor, or a distance sensor; the second sub-device 208 is an ambient light sensor, a color temperature sensor, a laser focus sensor, a distance sensor, or a soft light. In this way, the light-guiding structure 201 can be adapted to different application scenarios. It should be noted that, in some other possible implementations, the functional module 202 may also include a third sub-device, or the functional module 202 may also include a third sub-device and a fourth sub-device, that is, the functional module 202 includes multiple sub-devices, and the number of sub-devices may be 2, 3, 4, or 5, etc. The type of the sub-device may be any one of an ambient light sensor, a color temperature sensor, a laser focus sensor, a distance sensor, or a soft light, and of course, it may also be other devices.

In one embodiment, the first sub-component 207 is a soft light; the second sub-component 208 is an ambient light sensor; the ambient light sensor is used to detect the current external ambient light before the soft light is turned on to obtain a first ambient light brightness value; wherein, when the soft light is turned on, the brightness value of the display screen 101 of the electronic device 100 is determined according to the first ambient light brightness value and a preset ambient light brightness compensation value, so that the soft light and the ambient light sensor do not work at the same time, thereby avoiding the influence of the soft light on the ambient light sensor; since the brightness of the external environment will increase after the soft light is turned on, in order to increase the user experience, the brightness of the display screen 101 can be increased, so the brightness of the display screen after the soft light is turned on is determined according to the first ambient light brightness value and the preset ambient light brightness compensation value to increase the brightness of the display screen; The preset ambient light brightness compensation value can be a constant value, that is, the same compensation value is used during the day or at night. Of course, the preset ambient light brightness compensation value can also be a non-constant value as needed, that is, the preset ambient light brightness compensation value is in the form of a set, that is, including different sub-compensation values, to respectively deal with different environmental scenes, such as sunny days, cloudy days, nights, etc.; of course, the brightness value of the external ambient light before turning on the soft light can also be divided into different intervals, for example, into multiple sub-brightness value intervals, each sub-brightness value interval corresponds to a sub-compensation value, when the first ambient light brightness value is in the corresponding sub-brightness value interval, when the soft light is in the on state, the brightness value of the display screen 101 of the electronic device 100 is determined according to the first ambient light brightness value and the sub-compensation value corresponding to the first ambient light brightness value. The soft light has an on state and an off state. When the soft light is in the on state, the soft light emits light, and when the soft light is in the off state, the soft light does not emit light; when the soft light is in the on state, the brightness value of the display screen 101 is determined by the brightness value of the ambient light before the soft light is turned on, that is, by the first ambient light brightness value.

It should be noted that when one of the first sub-device 207 and the second sub-device 208 is a soft light and the other is a sensor (the other device is not limited to the ambient light sensor), the soft light and the sensor do not work at the same time, which can reduce the impact of the soft light on the sensor.

In some embodiments, a light path changing structure is provided in the light guide structure 201, and the light path changing structure is configured to reflect the external light entering the light guide structure 201 through the light-transmitting area 206 to the second sub-device 208. In this way, through the light path changing structure, more external light can be transmitted to the second sub-device 208. Of course, when the second sub-device 208 is a light-emitting device, more light will also be transmitted to the outside through the light path changing structure. Exemplarily, when the second sub-device 208 is an ambient light sensor, more external light is transmitted to the ambient light sensor through the light-transmitting area, thereby improving the detection sensitivity of the ambient light sensor.

It should be noted that, in some other possible implementations, scattering particles are arranged in the setting part of the main body 213, and the scattering performance is improved by the scattering particles, so that when the second sub-device 208 is an ambient light sensor, the external light is transmitted to the ambient light sensor through the light-transmitting area more, thereby improving the detection sensitivity of the ambient light sensor; in the thickness direction of the light guide structure 201, the area of the orthographic projection of the setting part is less than or equal to the area located at the second sub-surface 222. The material diameter of the scattering particles can be 0.3μm~0.8μm, and the scattering particles can be at least one of aluminum oxide powder, titanium oxide powder, and zirconium oxide powder.

In some embodiments, the optical path changing structure includes a first reflecting surface 224 and a second reflecting surface 225, wherein the first reflecting surface 224 is used to reflect the external light that enters the light guide structure 201 through the light-transmitting area 206 to the second reflecting surface 225, and the second reflecting surface 225 is used to reflect the external light reflected by the first reflecting surface 224 to the second sub-device 208. In this way, the first reflecting surface 224 and the second reflecting surface 225 provided in the light guide structure 201 can better realize the change in the light, and since the first reflecting surface 224 and the second reflecting surface 225 are provided in the light guide structure 201, it is beneficial to reduce the space occupied by the entire optical component.

As shown in combination with FIG. 7, FIG. 8 and FIG. 9, in some embodiments, the first reflection surface 224 is arranged at the connection between the first peripheral surface 214 of the main body 213 and the first sub-surface 221, the second reflection surface 225 is located at the third sub-surface 218 of the support portion 212, and the second reflection surface 225 is located above the second sub-surface 222; the first reflection surface 224 and the second reflection surface 225 are both planes, the first reflection surface 224 and the light-transmitting area 206 are arranged at an angle, and the second reflection surface 225 and the light-transmitting area 206 are parallel, because light will be scattered in the light-guiding structure 201, so that the light can be transmitted to the second sub-device 208 more efficiently. The first reflection surface 224 and the second reflection surface 225 are coated with a reflective coating, and the reflection of light is achieved by the reflective coating. The material of the reflective coating can be silver or aluminum.

As shown in Figures 8 and 9, in one embodiment, a portion of the edge of the first circumferential surface 214 is connected to a portion of the edge of the first sub-surface 221 through the first reflective surface 224, the second reflective surface 225 is a portion of the third sub-surface 218, and the second reflective surface 225 has a reflective coating facing the second sub-surface 222.

It should be noted that the number of reflective surfaces in the optical path changing structure is not limited to two, but can also be three, etc., and can be specifically designed according to actual conditions. In addition, in some other embodiments, the first reflective surface 224 is set at an angle to the light-transmitting area 206, and the second reflective surface 225 is also set at an angle to the light-transmitting area 206.

In combination with FIG. 3 , FIG. 4 and FIG. 7 , in one or more embodiments, the present application further provides an electronic device 100, which includes a display screen 101 and an optical component in any embodiment; the display screen 101 includes a display layer 102, the display layer 102 has a first opening 107, and the light-transmitting area 206 corresponds to the first opening 107. In this way, when the first sub-component 207 is a soft light lamp and the second sub-component 208 is an ambient light sensor, the distance between the flexible light and the ambient light sensor is small, so that the first opening 107 on the display screen 101 can be shared, thereby facilitating the transfer of the position of the ambient light sensor from the black border area to other positions of the screen, so as to improve the screen-to-body ratio of the display screen 101 by reducing the black border area on the periphery of the display screen 101; the first opening 107 is a stepped through hole; the hole wall of the first opening 107 also has a light shielding layer, so that in combination with the light shielding member 203, it is further ensured that the display layer 102 of the display screen 101 and the light guide structure 201 will not affect each other. In one embodiment, the first opening 107 is located at the top of the display screen 101.

As shown in FIG. 3 , FIG. 4 and FIG. 7 , the first opening 107 and the second opening 108 marked in FIG. 3 are only for indicating the positions of the first opening 107 and the second opening 108 when viewed from the appearance of the display screen, and do not indicate that the first opening 107 and the second opening 108 are opened on the cover layer 103 of the display screen 101. In some embodiments, the electronic device 100 further includes a housing 105, the display screen 101 is connected to the housing 105, the display screen 101 is supported by the housing 105, and an installation cavity is formed between the display screen 101 and the housing 105 to install other parts of the electronic device 100, such as the camera 106, the battery or the main board 104. The light guide structure 201 is installed on the housing 105, and the main board 104 is fixed on the housing 105, for example, a bracket is fixed in the housing 105, and the main board 104 is fixed on the bracket. The display layer 102 is also provided with a second opening 108, and the electronic device 100 also includes a camera 106, which is electrically connected to the mainboard 104; the camera 106 is located in the installation cavity, and the camera 106 corresponds to the second opening 108; the first opening 107 and the second opening 108 are arranged side by side, and the second opening 108 is located at the top of the display screen 101, so that the soft light can be called a front soft light, and the camera 106 can be called a front camera, and after the camera 106 and the light-guiding structure are arranged side by side, it is beneficial to make the functional coordination between the functional module 202 and the camera 106. The first opening 107 and the second opening 108 are located at the top of the display screen 101, and the midpoint of the line connecting the center of the first opening 107 and the center of the second opening 108 is located at the center line of the display screen 101. The center line of the display screen 101 is parallel to the length direction of the display screen 101, that is, from the top to the bottom of the display screen 101, the openings of the first opening 107 and the second opening 108 correspond to the cover layer 103, that is, only the display layer 102 is opened, and no hole is opened on the cover layer 103. It should be noted that only a partial structure of the main board 104 is shown in Figures 4 and 7.

In some embodiments, the electronic device 100 may be a mobile phone, a tablet computer, a laptop computer, or a desktop computer. The specific form of the electronic device 100 is not particularly limited in the embodiments of the present application. For the convenience of description and understanding, the electronic device 100 is described as a mobile phone. The electronic device 100 is a mobile phone, and the mobile phone is a straight-screen mobile phone. The housing 105 of the electronic device 100 is a middle frame. It should be noted that in some other embodiments, the mobile phone may also be a foldable mobile phone or other forms of mobile phones.

As shown in combination with FIG. 4 and FIG. 7 , in some embodiments, the display screen 101 further includes a cover layer 103, and the cover layer 103 covers the display layer 102; the area of the cover layer 103 opposite to the first opening 107 has a coating, and the light transmittance of the light-transmitting structure formed by the coating and the cover layer 103 is 12% to 18%, and the light transmittance can be 14%, 15% or 16%. In this way, the cover layer 103 is used to protect the display screen 101, and the coating is conducive to hiding the light-guiding structure 201 in appearance. Since the first opening 107 is a stepped through hole, the protrusion 211 of the light-guiding structure 201 can extend toward the first opening 107, which is conducive to reducing the distance between the light-transmitting area 206 and the cover. At least part of the structure of the shading member 203 extends into the first opening 107, so that after the shading member 203 is sandwiched between the cover layer 103 and the light-guiding structure 201, it is beneficial to reduce the influence of the optical components on the thickness of the electronic device after the optical components are installed in the electronic device; when the light passes through the display screen 101, it only passes through the cover layer 103 of the display screen 101, and does not pass through the physical area of the display layer 102 of the display screen 101, that is, the propagation path of the light at the display screen 101 is the cover layer 103 and the first opening 107. Specifically, the external light enters through the cover layer 103, and then enters the light-through hole 209 of the shading member 203 extending into the first opening 107, and then enters the light-guiding structure 201; and the light emitted by the functional module passes through the light-guiding structure 201, then through the light-through hole 209, and then through the cover layer 103 to be emitted.

In one embodiment, the first sub-device 207 and the second sub-device 208 are electrically connected to the mainboard 104 of the mobile phone, and the first sub-device 207 and the second sub-device 208 can be supported by the mainboard 104, and the first sub-device 207 and the second sub-device 208 are arranged side by side; and the coating includes two ink layers, from the cover layer 103 to the display layer 102, the two ink layers respectively include a semi-transparent black layer and a semi-transparent gray layer, and the semi-transparent gray layer is located between the semi-transparent black layer and the cover layer 103. For the semi-transparent black layer and the semi-transparent gray layer, the formulation of their respective components can be matched as needed, as long as the light transmittance of the light-transmitting structure formed by the coating and the cover layer 103 is 12% to 18%, so compared with the transmittance of the ambient light opening under the screen of 3% in the related art, the light transmittance of the present application is increased by about 5 times.

In some embodiments, the electronic device 100 further includes a processor (not shown), which can be integrated on the mainboard 104; the first sub-component 207 is a soft light, and the second sub-component 208 is an ambient light sensor; the ambient light sensor is used to detect the current external ambient light before the soft light is turned on to obtain a first ambient light brightness value; the processor is used to obtain a second ambient light brightness value according to the first ambient light brightness value and a preset ambient light brightness compensation value, and determine a target display screen brightness value according to the second ambient light brightness value, and turn on the soft light after determining the target display screen brightness value; wherein, when the soft light is turned on, the brightness value of the display screen 101 is the target display screen brightness value. Since the light of the soft light will be transmitted to the ambient light sensor through the light guide structure 201 during the turning on of the soft light, it will interfere with the ambient light sensor's detection of the external ambient light, so that the brightness value of the display screen 101 cannot be accurately determined; therefore, in the embodiment of the present application, before turning on the soft light, the ambient light is first detected, and when the soft light is turned on, the brightness value of the display screen 101 is the target display screen brightness value, thereby achieving a reasonable brightness value of the display screen 101. Referring to FIG. 10 , exemplarily, the working process of the soft light and the ambient light sensor is as follows: when the soft light is in the off state, the ambient light sensor detects the current ambient light, and the brightness value of the display screen 101 is adjusted according to the ambient light brightness value detected by the ambient light sensor; after the user issues a soft light turn-on instruction, the ambient light sensor detects the current external ambient light before the soft light is turned on, and obtains a first ambient light brightness value, and the processor then obtains a second ambient light brightness value based on the first ambient light brightness value and a preset ambient light brightness compensation value, and determines a target display screen brightness value based on the second ambient light brightness value. After the processor determines the target display screen brightness value, the soft light is turned on and kept on. At this time, the soft light is emitting light, and the brightness value of the display screen 101 during the soft light turning-on process is the target display screen brightness value, that is, when the soft light is emitting light, the brightness value of the display screen 101 is locked to the target display screen brightness value. After the user issues a soft light off command, the processor turns off the front soft light; when the soft light is off, the brightness value of the display screen 101 is unlocked, and then the ambient light sensor re-detects the current ambient light in real time, and the brightness value of the display screen 101 is adjusted according to the ambient light brightness value re-detected by the ambient light sensor, that is: when the soft light is off, the ambient light sensor detects the current ambient light, and the processor adjusts the brightness value of the display screen 101 according to the current ambient light brightness value.
