Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to an electronic device. Background Art

[0002] At present, ambient light sensors are installed in electronic devices such as smart wearable devices, mobile phones, tablets, laptops, large-screen display devices, etc. The ambient light sensors are used to sense the intensity of the ambient light around the electronic devices to perform corresponding optimization operations. For example, when the ambient light is detected to be weak, the backlight brightness of the screen is dimmed to avoid irritating the human eye, while also reducing power consumption.

[0003] The ambient light sensor is usually arranged inside the electronic device, and a light-transmitting window is provided on a surface component such as a screen, a back cover, etc., to introduce ambient light into the internal ambient light sensor.

[0004] On the basis of the above, the field of view (FOV) is a parameter to measure the field of view of the ambient light sensor. The larger the FOV, the larger the field of view, the greater the light efficiency of the received light (i.e., the ratio of the received light power to the incident light power), and the higher the detection accuracy. Usually, in order to obtain a larger FOV of the ambient light sensor, the ambient light sensor is usually set close to the light-transmitting window, and the ambient light sensor is electrically connected to the controller on the main circuit board with the help of a flexible circuit board, a printed circuit board, a spring, or other adapter structure. However, this inevitably increases the structural complexity and cost of the electronic device. Summary of the invention

[0005] The present application provides an electronic device for solving the problem of how to reduce the structural complexity and cost of the electronic device while ensuring the FOV of the ambient light sensor.

[0006] To achieve the above-mentioned purpose, the present application provides an electronic device, which includes a surface component, a circuit board, an ambient light sensor and a light equalizer. The first surface of the surface component forms a partial area of ​​the outer surface of the electronic device, and the surface component is provided with a light-transmitting window, and the ambient light outside the surface component can enter the inner side of the surface component through the light-transmitting window. The circuit board is located inside the electronic device, that is, the circuit board is located on the side of the surface component that is away from the first surface. The second surface of the circuit board faces the surface component. The ambient light sensor is provided on the second surface, and the light-sensitive surface of the ambient light sensor is opposite to the light-transmitting window. The light equalizer is provided in the light-transmitting window, or provided between the light-transmitting window and the light-sensitive surface.

[0007] In this way, the ambient light sensor is sunk onto the circuit board without the need for an adapter structure, which can reduce the structural complexity of the electronic device, save costs, and save the internal space of the electronic device, which is conducive to the thinning and miniaturization of the electronic device, and optimizes the internal space layout of the electronic device. Moreover, the ambient light sensor occupies a small area on the circuit board, and the utilization rate of the circuit board is high. At the same time, the light-distributing component plays a role in evenly dispersing the incident light, and can ensure the FOV and light efficiency of the ambient light sensor receiving light when the ambient light sensor is sunk to the circuit board.

[0008] In a possible implementation, when the light-distributing member is located between the light-transmitting window of the surface component and the photosensitive surface of the ambient light sensor, the light-distributing member is fixedly arranged on the third surface of the surface component and covers at least part of the light-transmitting window, and the light-distributing member is in contact with or spaced apart from the photosensitive surface of the ambient light sensor. In this way, on the first hand, it is convenient to set the light-distributing member on the surface component so that the light-distributing member can cover the entire light-transmitting window. On the second hand, the light-distributing member is bound together with the surface component, the distance between the light-distributing member and the light-transmitting window is small, and the light efficiency of receiving ambient light is large, which is conducive to increasing the light efficiency of ambient light received by the ambient light sensor. On the third hand, the light-distributing member maintains a certain distance from the display panel, which can reduce the visibility of the light-distributing member and ensure the appearance effect of the surface component. On the fourth hand, while the light-distributing member is bound together with the surface component, the ambient light sensor is bound together with the circuit board, and the light-distributing member and the ambient light sensor are independent of each other, which can realize the unbinding of the ambient light sensor and the surface component. Fifthly, the ambient light sensor is bound to the circuit board, and it is easier to set up a protective cover and other measures on the circuit board to protect the ambient light sensor, and the probability of damage to the ambient light sensor during process operation is lower.

[0009] In one possible implementation, when the light-distributing member is spaced apart from the photosensitive surface of the ambient light sensor, the electronic device further includes a light guide, which is located between the light-distributing member and the photosensitive surface, and is fixedly disposed on the photosensitive surface, and is in contact with or spaced apart from the light-distributing member. Alternatively, the light guide is fixedly disposed on the light-distributing member, and is in contact with or spaced apart from the photosensitive surface. In this way, on the one hand, the light leakage transmitted from the light-distributing member to the ambient light sensor can be avoided with the aid of the light guide, and the light efficiency of the ambient light sensor receiving light can be improved. On the other hand, since the light guide is fixed to the photosensitive surface, the light guide is in contact with or spaced apart from the light-distributing member; or, the light guide is fixed on the light-distributing member, and is in contact with or spaced apart from the photosensitive surface, the ambient light sensor and the surface component can also be untied.

[0010] In a possible implementation, when the light-evening element is separated from the light-sensitive surface of the ambient light sensor, the electronic device further includes a middle frame, and the middle frame is provided with a light-through hole. The surface component and the light-evening element are located on one side of the middle frame, the circuit board and the ambient light sensor are located on the other side of the middle frame, and the light-through hole is located between the light-transmitting window of the surface component and the light-sensitive surface of the ambient light sensor.

[0011] In a possible implementation, the electronic device further includes a light guide, which is located between the light equalizer and the photosensitive surface, and at least a portion of the light guide is accommodated in the light hole. The light guide is fixedly disposed on the photosensitive surface, and the light guide is in contact with or spaced apart from the light equalizer; or, the light guide is fixedly disposed on the light equalizer, and the light guide is in contact with or spaced apart from the photosensitive surface. In this way, under the premise of the existence of the middle frame, light leakage can still be avoided, and the ambient light sensor can be untied from the surface component.

[0012] In a possible implementation, the light homogenizer includes a light homogenizer body, and the color of the light homogenizer body is white, or the color of the light homogenizer body as a whole or in part is dark. When the color of the light homogenizer body is white, the light homogenizer has a better light homogenizing effect, and when the color of the light homogenizer body as a whole or in part is dark, the visibility of the light homogenizer is lower and the appearance is better.

[0013] In one possible implementation, the light homogenizer body is in the form of a film, and the thickness of the light homogenizer body is greater than or equal to 0.01 mm and less than or equal to 0.3 mm. When the thickness of the light homogenizer is within this range, the thickness of the light homogenizer is small, which is conducive to the thinning of the thickness of the electronic device. Moreover, the reflectivity of the light is low and the transmittance is high, which can reduce the visibility of the light homogenizer and improve the light efficiency and FOV of the ambient light sensor.

[0014] In a possible implementation, the light homogenizer includes a light homogenizer body and a light shielding member, and the light shielding member is located on a side of the light homogenizer body close to the first surface. In this way, the light homogenizer has lower visibility and better appearance.

[0015] In a possible implementation, the shading element includes a dark light-transmitting film or a polarizing film. This structure is simple and easy to form.

[0016] In a possible implementation, the shading member includes a dark layer, and the dark layer is provided with at least one first through hole. This structure is simple and convenient to manufacture.

[0017] In a possible implementation, the dark layer is a dark ink layer or a dark tape.

[0018] In a possible implementation, the light-distributing member body is in the shape of a rectangular film. There are multiple first through holes, and the multiple first through holes are arranged along an elliptical array. The long axis of the elliptical array trajectory of the multiple first through holes is parallel to the long side of the light-distributing member body, and the short axis of the elliptical array trajectory of the multiple first through holes is parallel to the short side of the light-distributing member body. With this design, the light-distributing member has low visibility and good appearance performance, and the FOV of the ambient light sensor is better.

[0019] In a possible implementation, the distance between the light-evening element body and the ambient light sensor is greater than or equal to 0 mm and less than or equal to 5 mm. In this way, the distance between the light-evening element body and the ambient light sensor is moderate, the central light intensity and optical power of the received light of the ambient light sensor are large, the detection accuracy of the ambient light sensor can be improved, and the thin design of the electronic device is also beneficial.

[0020] In a possible implementation manner, the surface component is a screen.

[0021] In a possible implementation, the screen includes a display panel, and the distance between the light-distributing member body and the display panel is greater than or equal to 0 mm and less than or equal to 1 mm. In this way, the distance between the light-distributing member body and the display panel is moderate, which can take into account the visibility of the light-distributing member and the optical power and FOV of the received light of the ambient light sensor.

[0022] In a possible implementation, the screen includes a light-transmitting cover plate, a display panel, and a protective layer, which are stacked in sequence. The surface of the light-transmitting cover plate facing away from the display panel forms a first surface. A second through hole is provided on the protective layer, and the portion of the display panel opposite to the second through hole is a first light-transmitting portion, and the portion of the light-transmitting cover plate opposite to the second through hole is a second light-transmitting portion. The second through hole, the first light-transmitting portion, and the second light-transmitting portion constitute at least part of the light-transmitting window. The second through hole forms a non-physical portion of the light-transmitting window, and the first light-transmitting portion and the second light-transmitting portion form a physical material portion of the light-transmitting window. In this way, a portion of the light-transmitting window is a physical material portion, which can prevent impurities such as water and dust from entering, while ensuring the integrity of the display panel and the display effect, and since the other portion of the light-transmitting window is a non-physical portion, it is possible to save material costs and reduce the difficulty of production.

[0023] In a possible implementation, the light-transmitting window is a rectangular window. The length of the rectangular window is greater than or equal to 0.5 mm and less than or equal to 10 mm. The width of the rectangular window is greater than or equal to 0.5 mm and less than or equal to 10 mm. When the size of the light-transmitting window is within this range, the optical power and FOV of the received light of the ambient light sensor are better, and can meet the detection requirements of the ambient light sensor.

[0024] In a possible implementation, an annular adhesive layer is provided between the third surface and the light-distributing member, and the annular adhesive layer is provided around a circumference of the light-transmitting window. At least one notch is provided on the annular extension path of the annular adhesive layer, and the notch connects the inner and outer sides of the annular adhesive layer. Since the notch connects the inner and outer sides of the annular adhesive layer, it is possible to prevent a closed space from being formed inside the annular adhesive layer, thereby preventing the inner space of the annular adhesive layer from generating air bubbles when heated, thereby squeezing the display panel, and thus preventing display defects.

[0025] In a possible implementation, the light-transmitting window is a rectangular window; the rectangular window includes a first edge and a second edge relative to each other, and a third edge and a fourth edge relative to each other. The annular adhesive layer includes a first adhesive segment and a second adhesive segment relative to each other, and a third adhesive segment and a fourth adhesive segment relative to each other. The first adhesive segment is located on a side of the first edge away from the second edge, and extends along the length direction of the first edge. The second adhesive segment is located on a side of the second edge away from the first edge, and extends along the length direction of the second edge. The third adhesive segment is located on a side of the third edge away from the fourth edge, and extends along the length direction of the third edge. The fourth adhesive segment is located on a side of the fourth edge away from the third edge, and extends along the length direction of the fourth edge. The first adhesive segment, the third adhesive segment, the second adhesive segment, and the fourth adhesive segment are connected end to end in sequence. At least one notch includes a first notch, a second notch, a third notch, and a fourth notch, the first notch is provided in the first adhesive segment, the second notch is provided in the second adhesive segment, the third notch is provided in the third adhesive segment, and the fourth notch is provided in the fourth adhesive segment. In this way, the four gaps achieve uniform connectivity between the inner and outer sides of the annular adhesive layer, which can effectively prevent the formation of a closed space inside the annular adhesive layer, thereby effectively preventing the inner space of the annular adhesive layer from generating air bubbles when heated, thereby squeezing the display panel and effectively avoiding display defects.

[0026] In a possible implementation, the projection area of ​​the photosensitive surface on the first surface is smaller than the projection area of ​​the light-transmitting window on the first surface, and the projection of the photosensitive surface on the first surface is located within the projection of the light-transmitting window on the first surface. In this way, the difficulty of aligning the ambient light sensor and the light-transmitting window can be reduced, the error tolerance rate can be improved, and the assembly efficiency can be improved.

[0027] In a possible implementation, the electronic device further includes a middle frame, the surface component is located on one side of the middle frame, the circuit board and the ambient light sensor are located on the other side of the middle frame, and a light hole is provided on the portion of the middle frame between the light-transmitting window and the light-sensitive surface, and the light-distributing member is provided on the middle frame, and the light-distributing member covers at least a portion of the light hole. In this way, the ambient light sensor and the surface component can also be untied.

[0028] In a possible implementation, the light-distributing member is disposed on the light-sensitive surface, and the light-distributing member is in contact with or spaced apart from the surface component. In this way, the ambient light sensor and the surface component can also be untied.

[0029] In a possible implementation, the electronic device is a smart watch or a mobile phone. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] See also Figure 1 and Figure 2 , Figure 1 A perspective view of an electronic device 100 provided in some embodiments of the present application, Figure 2 for Figure 1 The schematic diagram of the exploded structure of the main part of the electronic device 100 is shown. This embodiment is exemplified by taking the electronic device 100 as a smart watch. The electronic device 100 includes a surface component 10. The surface component 10 refers to a component on the electronic device 100 that can be viewed or touched by a user from the outside.

[0065] In some embodiments, see Figure 1 and Figure 2 , the surface component 10 is a screen.

[0066] On the basis of the above, in order to facilitate the description of each embodiment below, an XYZ coordinate system is established for the electronic device 100. Specifically, the plane parallel to the screen is defined as the XY plane, and the thickness direction of the screen is defined as the Z axis direction. It can be understood that the coordinate system setting of the electronic device 100 can be flexibly set according to actual needs, and no specific limitation is made here.

[0067] The surface component 10 includes a first surface S1, and the first surface S1 forms at least a portion of the outer surface of the electronic device 100. When the surface component 10 is a screen, please refer to Figure 1 and Figure 2 The first surface S1 may be a surface on a screen for presenting images and videos to a user.

[0068] A light-transmitting window 10a is provided on the surface component 10. The light-transmitting window 10a is used to achieve light communication between the inner and outer sides of the surface component 10, that is, ambient light outside the surface component 10 can enter the inner side of the surface component 10 through the light-transmitting window 10a.

[0069] See also Figure 1 and Figure 2 , the light-transmitting window 10a may be a rectangular window, the long side of the rectangular window is parallel to the X-axis, and the short side of the rectangular window is parallel to the Y-axis. It should be noted that the sides of the light-transmitting window 10a described in this embodiment and the following embodiments are described on the basis of ignoring the depth of the light-transmitting window 10a and treating the light-transmitting window 10a as a plane structure. The rectangle described in the present application includes a square with two adjacent sides of different lengths and a square with two adjacent sides of the same length.

[0070] In other embodiments, the light-transmitting window 10a may also be a substantially circular window, an elliptical window, a triangular window, a polygonal window, or the like.

[0071] This embodiment and the following embodiments are illustrative in that the light-transmitting window 10a is a rectangular window, which cannot be regarded as a special limitation to the present application.

[0072] The light-transmitting window 10a can be a non-physical opening, or a physical light-transmitting or semi-light-transmitting material, or a part of it can be a non-physical opening and a part of it can be a physical light-transmitting or semi-light-transmitting material, which is not specifically limited here. The light-transmitting or semi-light-transmitting material can be glass, sapphire, display panel, etc., which is not specifically limited here.

[0073] In some embodiments, see Figure 3 , Figure 3 for Figure 1 The cross-sectional structure diagram of the electronic device 100 at line AA is shown. The screen includes a light-transmitting cover plate 11, a display panel 12 and a protective layer 13 which are stacked in sequence.

[0074] The transparent cover plate 11 is used to protect the display panel 12 from water, dust and scratches. The surface of the transparent cover plate 11 facing away from the display panel 12 forms the first surface S1. The material of the transparent cover plate 11 includes but is not limited to acrylic, glass and sapphire. In other embodiments, the screen may not be provided with the transparent cover plate 11 but a polarizing film may be used to protect the display panel 12, which is not specifically limited here.

[0075] The display panel 12 may be a self-luminous display panel. For example, the display panel 12 may be an organic light-emitting diode (OLED) display panel, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display panel, a mini organic light-emitting diode (MIL-E) display panel, a micro organic light-emitting diode (MIL-E) display panel, a micro organic light-emitting diode (MIL-E) display panel, and a quantum dot light-emitting diode (QLED) display panel. In other embodiments, the display panel 12 may also be a display panel that is not self-luminous and needs to be provided with backlight by a backlight module. For example, the display panel 12 may be a liquid crystal display panel (LCD).

[0076] The protective layer 13 is used to support, buffer or protect the display panel 12 from static electricity. The protective layer 13 can be formed by stacking a plurality of layers of different materials. For example, the protective layer 13 can be formed by stacking a polyimide film (PI) layer, a foam layer and a metal layer. The PI layer is used to support the display panel 12, the foam layer is used to buffer, and the metal layer is used to protect from static electricity.

[0077] On the basis of the above, please continue to refer to Figure 3, a second through hole 10a1 is provided on the protective layer 13. The portion of the display panel 12 opposite to the second through hole 10a1 is light-transmissive, and the portion of the display panel 12 opposite to the second through hole 10a1 is defined as a first light-transmissive portion 10a2. The portion of the light-transmissive cover plate 11 opposite to the second through hole 10a1 is defined as a second light-transmissive portion 10a3. The second through hole 10a1, the first light-transmissive portion 10a2 and the second light-transmissive portion 10a3 constitute at least part of the above-mentioned light-transmissive window 10a. Of course, when the screen also includes other structures, the light-transmissive window 10a also includes other parts. The second through hole 10a1 forms a non-substantial portion of the light-transmissive window 10a, and the first light-transmissive portion 10a2 and the second light-transmissive portion 10a3 form a substantial material portion of the light-transmissive window 10a. In this way, a part of the light-transmitting window 10a is a solid material part, which can prevent impurities such as water and dust from entering, while ensuring the integrity of the display panel 12 and the display effect. Moreover, since the other part of the light-transmitting window 10a is a non-solid part, it can save material costs and reduce production difficulty.

[0078] Please also read Figure 2 and Figure 3 The electronic device 100 further includes a circuit board 20 , an ambient light sensor 30 and a transfer structure 40 .

[0079] The circuit board 20 is located on a side of the surface component 10 that is away from the first surface S1 .

[0080] The circuit board 20 may be a hard circuit board, a flexible circuit board, or a hard-soft circuit board. This embodiment is exemplified by taking the circuit board 20 as a hard circuit board. Specifically, the circuit board 20 may be a hard printed circuit board (PCB). A first controller may be provided on the circuit board 20. The first controller includes but is not limited to a microcontroller unit (MCU). The first controller is used to control the ambient light sensor 30 to detect the ambient light brightness.

[0081] The circuit board 20 can be a main circuit board or other circuit boards, such as a sub-circuit board, etc. Among them, the main circuit board is also called the main board, and the main circuit board is the core circuit board in the electronic device 100. The main circuit board generally refers to a circuit board with a processor integrated in the electronic device 100. Among them, the processor may include one or more processing units, for example: the processor may include an application processor (application processor, AP), a modem processor, a graphics processor (graphics processing unit, GPU), an image signal processor (image signal processor, ISP), a controller, a video codec, a digital signal processor (digital signal processor, DSP), a baseband processor and / or a neural network processor (neural-network processing unit, NPU), etc. Different processing units can be independent devices or integrated in one or more processors.

[0082] The ambient light sensor 30 is located between the surface component 10 and the circuit board 20 . The ambient light sensor 30 includes a photosensitive surface 31 . The photosensitive surface 31 is opposite to the light-transmitting window 10 a . The ambient light from the light-transmitting window 10 a can enter the ambient light sensor 30 to detect the brightness of the ambient light.

[0083] The ambient light sensor 30 is fixed on the surface component 10. In this way, the ambient light sensor 30 is closer to the light-transmitting window 10a, which is conducive to increasing the FOV of the ambient light sensor 30, increasing the field of view of the ambient light sensor 30, and improving the light efficiency and detection accuracy of the ambient light sensor 30.

[0084] It should be noted that the FOV described in the embodiment of the present application refers to: taking the light intensity received by the sensor at 0°, i.e., the normal viewing angle, as the first light intensity, as the receiving angle increases, when the light intensity received by the sensor is reduced to half of the first light intensity, the corresponding total light receiving angle.

[0085] The adapter structure 40 is used to realize the electrical connection between the ambient light sensor 30 and the circuit board 20 , so as to output the detection result of the ambient light sensor 30 to the circuit board 20 .

[0086] In some embodiments, see Figure 2 and Figure 3 The transfer structure 40 may be a flexible printed circuit board (FPC). One end of the FPC is electrically connected to the ambient light sensor 30, and the other end is electrically connected to the circuit board 20 by means of a connection structure such as a board-to-board (BTB) connector.

[0087] In some other embodiments, see Figure 4 , Figure 4 The schematic diagram of the cross-sectional structure of the electronic device 100 provided in some embodiments of the present application, the adapter structure 40 may also include an adapter plate 41 and a plurality of metal springs 42, the ambient light sensor 30 is arranged on the adapter plate 41, and the adapter plate 41 is electrically connected to the circuit board 20 by means of the plurality of metal springs 42. In addition to the function of electrical connection, the metal springs 42 are also used to raise the adapter plate 41 to reduce the distance between the ambient light sensor 30 and the light-transmitting window 10a.

[0088] The above-mentioned method of electrically connecting the ambient light sensor 30 and the circuit board 20 by means of the adapter structure 40 is complex in structure and high in cost. Moreover, the adapter structure 40 occupies a large volume and area in the electronic device 100, which is not conducive to miniaturization and thinning of the electronic device 100.

[0089] At the same time, in order to control the overall thickness of the electronic device, a certain area needs to be reserved at the position on the circuit board 20 opposite to the adapter structure 40 to avoid the adapter structure 40. No electronic components are set in this area or only electronic components with a smaller height are set, resulting in reduced utilization of the circuit board 20 and limited layout of the circuit board 20.

[0090] Moreover, the ambient light sensor 30 is bound together with the surface component 10, and the ambient light sensor 30 protrudes from the inner surface of the surface component 10. After the ambient light sensor 30 is assembled on the surface component 10, it is easy to be bumped during transportation and further assembly, resulting in the ambient light sensor 30 and the adapter structure 40 being separated from the surface component 10, or causing damage to the ambient light sensor 30 and the adapter structure 40.

[0091] On the basis of the above, in order to reduce the structural complexity of the electronic device 100, please refer to Figure 5 , Figure 5 The cross-sectional structure diagram of the electronic device 100 provided in some embodiments of the present application is shown in FIG. 1. In this embodiment, the electronic device 100 includes a surface component 10, a circuit board 20 and an ambient light sensor 30.

[0092] The surface component 10 may be the surface component 10 described in any of the above embodiments.

[0093] The circuit board 20 is located inside the electronic device 100. Specifically, the circuit board 20 is disposed on the side of the surface component 10 that is opposite to the first surface S1. The structure of the circuit board 20 can be the circuit board 20 described in any of the above embodiments, and the circuit board 20 includes a second surface S2, and the second surface S2 faces the above surface component 10.

[0094] The ambient light sensor 30 is disposed on the second surface S2. In some embodiments, the second surface S2 is provided with a pad, and the ambient light sensor 30 can be soldered on the pad using surface mount technology (SMT). In other embodiments, the ambient light sensor 30 can also be soldered on the second surface S2 using plug-in technology, which is not specifically limited here.

[0095] On the basis of the above, the ambient light sensor 30 includes a light-sensitive surface 31 , and the light-sensitive surface 31 is opposite to the light-transmitting window 10 a .

[0096] In this way, the ambient light sensor 30 is sunk onto the circuit board 20, and no adapter structure is required for the adapter, which can reduce the structural complexity of the electronic device 100, save costs, and save the internal space of the electronic device, which is conducive to the thinning and miniaturization of the electronic device 100, and optimizes the internal space layout of the electronic device. In addition, the ambient light sensor 30 occupies a small area on the circuit board 20, and the utilization rate of the circuit board 20 is high.

[0097] On the basis of the above, in order to ensure the FOV of the ambient light sensor 30, in some embodiments, please continue to refer to Figure 5 The electronic device 100 further includes a light-distributing member 50 . The light-distributing member 50 is disposed in the light-transmitting window 10 a , or between the light-transmitting window 10 a and the photosensitive surface 31 . Figure 5 The light homogenizing member 50 is disposed between the light-transmitting window 10 a and the photosensitive surface 31 for exemplary description, which cannot be regarded as a special limitation to the present application.

[0098] The light homogenizing member 50 plays a role in uniformly dispersing the incident light, and can ensure the FOV and light efficiency of the ambient light sensor 30 receiving light when the ambient light sensor 30 is lowered to the circuit board 20 .

[0099] The following mainly introduces the light homogenizing element 50 from three aspects: the setting position, structural form, size, and the distance between the light homogenizing element 50 and the light-transmitting window 10 a and the photosensitive surface 31 .

[0100] First, the location of the light homogenizing member 50 will be described.

[0101] In some embodiments, the light homogenizing member 50 may be disposed in the light-transmitting window 10a. Figure 3 When the light-transmitting window 10a includes the second through hole 10a1, the first light-transmitting portion 10a2 and the second light-transmitting portion 10a3, the light-distributing member 50 can be disposed in the second through hole 10a1. In this way, the light-distributing member 50 and the surface component 10 can be prevented from overlapping in thickness, which is conducive to reducing the thickness of the electronic device 100.

[0102] In some other embodiments, see Figure 5 The light homogenizing member 50 may be disposed between the light-transmitting window 10 a and the photosensitive surface 31 .

[0103] On the basis of the above, optional, please continue to refer to Figure 5 The surface component 10 further includes a third surface S3, which is opposite to the first surface S1 and faces the second surface S2. The light homogenizing member 50 is fixed to the third surface S3 and covers at least a portion of the light-transmitting window 10a.

[0104] The light homogenizer 50 covers at least a portion of the light-transmitting window 10 a , which means that the projection of the light homogenizer 50 on the third surface S3 overlaps with the projection of the light-transmitting window 10 a on the third surface S3 .

[0105] In some embodiments, please refer to Figure 5 and Figure 6 , Figure 6 for Figure 5 The schematic diagram of the inner surface of the assembly structure of part of the surface component 10 in the electronic device 100 and the light uniformizer 50 is shown, and the light uniformizer 50 covers the entire light-transmitting window 10a, that is, the projection of the light-transmitting window 10a on the third surface S3 is located within the projection of the light uniformizer 50 on the third surface S3.

[0106] In this way, firstly, it is convenient to set the light-distributing member 50 on the surface component 10, so that the light-distributing member 50 can cover the entire light-transmitting window 10a. Secondly, the light-distributing member 50 is bound to the surface component 10, and the distance between the light-distributing member 50 and the light-transmitting window 10a is small, and the light efficiency of receiving ambient light is large, which is conducive to increasing the light efficiency of ambient light received by the ambient light sensor 30. Thirdly, the light-distributing member 50 is kept at a certain distance from the display panel 12, which can reduce the possibility of the user seeing the light-distributing member 50 through the light-transmitting window 10a from the side facing the surface S1, that is, reduce the visibility of the light-distributing member 50, and ensure the appearance effect of the surface component 10.

[0107] In the above embodiment, the light homogenizing member 50 can be glued and fixed to the third surface S3. Figure 5 An annular adhesive layer 60 is disposed between the third surface S3 and the light-distributing member 50. The material of the annular adhesive layer 60 includes but is not limited to ultraviolet rays (UV) curing adhesive, epoxy AB adhesive and quick-drying adhesive.

[0108] See also Figure 7 , Figure 7 for Figure 5The schematic diagram of the relative position of the surface component 10 and the annular adhesive layer 60 in the electronic device 100 is shown. The annular adhesive layer 60 is arranged around the light-transmitting window 10a. At least one notch is arranged on the annular extension path of the annular adhesive layer 60, and the notch connects the inner and outer sides of the annular adhesive layer 60.

[0109] The inner side of the annular adhesive layer 60 refers to a space surrounded by the annular adhesive layer 60 , which is connected to the second through hole 10 a 1 of the light-transmitting window 10 a . The outer side of the annular adhesive layer 60 refers to a space located outside the annular adhesive layer 60 .

[0110] Since the gap connects the inner and outer sides of the annular adhesive layer 60 , a closed space can be prevented from being formed inside the annular adhesive layer 60 , thereby preventing air bubbles from being generated inside the annular adhesive layer 60 when heated, thereby preventing the display panel from being squeezed and display defects from being generated.

[0111] In the above embodiment, the number of the notches may be one or more, which is not specifically limited herein.

[0112] In some embodiments, please refer to Figure 7 The light-transmitting window 10a includes an opposite first edge b1 and a second edge b2, and an opposite third edge b3 and a fourth edge b4.

[0113] The annular adhesive layer 60 includes a first adhesive segment 61 and a second adhesive segment 62 that are opposite to each other, and a third adhesive segment 63 and a fourth adhesive segment 64 that are opposite to each other.

[0114] The first adhesive material section 61 is located on a side of the first edge b1 away from the second edge b2, and extends along the length direction of the first edge b1. The second adhesive material section 62 is located on a side of the second edge b2 away from the first edge b1, and extends along the length direction of the second edge b2. The third adhesive material section 63 is located on a side of the third edge b3 away from the fourth edge b4, and extends along the length direction of the third edge b3. The fourth adhesive material section 64 is located on a side of the fourth edge b4 away from the third edge b3, and extends along the length direction of the fourth edge b4.

[0115] The first glue material section 61, the third glue material section 63, the second glue material section 62, and the fourth glue material section 64 are connected end to end in sequence. The at least one notch includes a first notch 60a, a second notch 60b, a third notch 60c, and a fourth notch 60d. The first notch 60a is provided in the first glue material section 61. In some embodiments, the first notch 60a is provided at the midpoint of the length direction of the first glue material section 61. The second notch 60b is provided in the second glue material section 62. In some embodiments, the second notch 60b is provided at the midpoint of the length direction of the second glue material section 62. The third notch 60c is provided in the third glue material section 63. In some embodiments, the third notch 60c is provided at the midpoint of the length direction of the third glue material section 63. The fourth notch 60d is provided in the fourth glue material section 64. In some embodiments, the fourth notch 60d is provided at the midpoint of the length direction of the fourth glue material section 64.

[0116] In this way, the four gaps achieve uniform communication between the inner and outer sides of the annular adhesive layer 60, which can effectively prevent the formation of a closed space inside the annular adhesive layer 60, thereby effectively preventing the inner space of the annular adhesive layer 60 from generating air bubbles when heated, thereby squeezing the display panel and effectively avoiding poor display.

[0117] Based on the above, please refer back to Figure 5 , the light homogenizer 50 is spaced apart from the ambient light sensor 30 , that is, there is a gap between the light homogenizer 50 and the ambient light sensor 30 .

[0118] In this way, while the light-distributing member 50 is bound to the surface member 10, the ambient light sensor 30 is bound to the circuit board 20. The light-distributing member 50 and the ambient light sensor 30 are independent of each other, and the ambient light sensor 30 can be untied from the surface member 10. At the same time, the ambient light sensor 30 is bound to the circuit board 20, and it is easier to set a protective cover or other measures on the circuit board 20 to protect the ambient light sensor 30, and the ambient light sensor 30 is less likely to be damaged during the process operation.

[0119] In some other embodiments, the light homogenizing member 50 and the ambient light sensor 30 may also be in contact with each other. The "contact" described in this embodiment and the following embodiments means that the two touch each other, but there is no fixing structure such as glue between the two. This can also achieve the unbinding of the ambient light sensor 30 and the surface component 10.

[0120] In some embodiments, see Figure 8 , Figure 8 for Figure 5 The top view of the assembly structure of the circuit board 20 and the ambient light sensor 30 in the electronic device 100 is shown, and the light-sensitive surface 31 of the ambient light sensor 30 is located on the surface of the ambient light sensor 30 facing away from the circuit board 20. Fig. 9 , Fig. 9 for Figure 5 The schematic diagram of the relative position of the ambient light sensor 30 and the light-transmitting window 10a in the electronic device 100 is shown. The projection area of ​​the photosensitive surface 31 on the first surface S1 is smaller than the projection area of ​​the light-transmitting window 10a on the first surface S1, and the projection of the photosensitive surface 31 on the first surface S1 is located within the projection of the light-transmitting window 10a on the first surface S1. In this way, the difficulty of aligning the ambient light sensor 30 and the light-transmitting window 10a can be reduced, the error tolerance rate can be improved, and the assembly efficiency can be improved.

[0121] When the ambient light sensor 30 is spaced apart from the light homogenizing member 50, optionally, see Fig.10 , Fig.10 Schematic diagram of the cross-sectional structure of the electronic device 100 provided in some embodiments of the present application. In this embodiment, the electronic device 100 further includes a light guide 70, and the light guide 70 is located between the light homogenizing member 50 and the light-sensitive surface 31 of the ambient light sensor 30. Fig.11 , Fig.11 for Fig.10 The schematic diagram of the assembly structure of the circuit board 20, the ambient light sensor 30 and the light guide 70 in the electronic device 100 is shown. The light guide 70 is fixed to the light sensitive surface 31. Fig.12 , Fig.12 for Fig.10 The schematic diagram of the relative positions of the inner surface component 10, the light equalizing member 50, the light guide 70 and the ambient light sensor 30 of the electronic device 100 is shown, and the light guide 70 is in contact with or separated from the light equalizing member 50. Alternatively, the light guide 70 is fixed on the light equalizing member 50, and the light guide 70 is in contact with or separated from the light sensitive surface 31.

[0122] In this way, on the one hand, the light guide 70 can prevent the light transmitted from the light equalizer 50 to the ambient light sensor 30 from leaking, and can improve the light efficiency of the ambient light sensor 30 receiving light. On the other hand, since the light guide 70 is fixed to the light sensitive surface 31, the light guide 70 is in contact with or spaced apart from the light equalizer 50; or the light guide 70 is fixed to the light equalizer 50, the light guide 70 is in contact with or spaced apart from the light sensitive surface 31, the ambient light sensor 30 can also be untied from the surface component 10.

[0123] In the above embodiment, the light guide 70 may be in a columnar shape, a block shape, a sheet shape, etc. This embodiment is exemplified by taking the light guide 70 in a columnar shape. The material of the light guide 70 includes but is not limited to acrylic or polycarbonate (PC) with light guide points.

[0124] In some other embodiments, the light guide 70 is fixed to the light sensitive surface 31, and the light guide 70 is also fixed to the light equalizer 50. In this way, the surface component 10, the light equalizer 50, the light guide 70, the ambient light sensor 30 and the circuit board 20 are connected as a whole, which is conducive to improving the structural stability of the electronic device.

[0125] In some other embodiments, the light guide 70 may not be provided between the light equalizer 50 and the ambient light sensor 30. On this basis, the ambient light sensor 30 and the light equalizer 50 are directly fixed together by means of adhesive. In this way, the surface component 10, the light equalizer 50, the ambient light sensor 30 and the circuit board 20 are connected as a whole, which is conducive to improving the structural stability of the electronic device.

[0126] When the light-distributing member 50 is disposed between the light-transmitting window 10a and the photosensitive surface 31, the light-distributing member 50 may optionally be disposed on other structures between the light-transmitting window and the ambient light sensor. For example, when the electronic device 100 is a mobile phone, the electronic device 100 may further include a middle frame, and the middle frame is located between the light-transmitting window 10a and the photosensitive surface 31. On this basis, the light-distributing member 50 may be disposed on the middle frame.

[0127] Specifically, a portion of the middle frame between the light-transmitting window 10a and the photosensitive surface 31 is provided with a light-through hole, and a light-distributing member 50 is provided on the middle frame, and the light-distributing member 50 covers at least a portion of the light-through hole. The light-distributing member 50 may be provided on the surface of the middle frame facing the surface component 10, or on the surface of the middle frame facing the circuit board, or at other locations, which are not specifically limited here.

[0128] When the light-distributing member 50 is disposed between the light-transmitting window 10a and the photosensitive surface 31, the light-distributing member 50 can also be disposed on the photosensitive surface 31 of the ambient light sensor 30. Specifically, the light-distributing member 50 can be bonded to the photosensitive surface 31 by means of adhesive. On this basis, the light-distributing member 50 can be in contact with the surface component 10 or can be spaced apart. In this way, the ambient light sensor 30 and the surface component 10 can also be untied.

[0129] Next, the structure of the light homogenizing member 50 will be described below.

[0130] See also Fig.13 , Fig.13 The light homogenizer 50 is a schematic structural diagram of some embodiments of the present application. The light homogenizer 50 may include a light homogenizer body 51.

[0131] The color of the light homogenizer body 51 may be white. The shape of the light homogenizer body 51 includes but is not limited to a film, a sheet, a plate or a block. Fig.13The following embodiments are exemplified by the light homogenizer body 51 being in the form of a film, which cannot be considered as a special limitation of the present application. When the light homogenizer body 51 is in the form of a film, the thickness of the light homogenizer body 51 is small, which is conducive to the thinning of the electronic device 100.

[0132] The light homogenizer body 51 may include a substrate 511 and diffusion particles 512 .

[0133] The substrate 511 may be made of a material with high transmittance (light transmittance greater than or equal to 85%), such as polyethylene terephthalate, polymethyl methacrylate, and the like.

[0134] The diffusion particles 512 may be selected to have a particle size greater than or equal to 50 nanometers (nm) and less than or equal to 100 micrometers (um). Specifically, the particle size of the diffusion particles 512 may be 50nm, 100nm, 200nm, 500nm, 1um, 10um, 20um, 30um, 40um, 50um, 70um, 80um, 90um or 100um.

[0135] The material of the diffusion particles 512 includes but is not limited to acrylic microspheres (such as polymethyl methacrylate, etc.), polystyrene microspheres, silicone microspheres (such as silicon dioxide, etc.), calcium carbonate microspheres, titanium oxide and metal particles, etc.

[0136] There are many ways to dispose the diffusion particles 512 on the substrate 511 .

[0137] For examples, see Fig.13 , the diffusion particles 512 are evenly dispersed in the substrate 511. This structure can prevent the diffusion particles 512 from falling off by wrapping the diffusion particles 512 with the help of the substrate 511, so that the structural stability of the light-homogenizing element body 51 is relatively high.

[0138] The processing process of the above-mentioned light homogenizing element body 51 can be: firstly, the base material 511 is melted at high temperature; then, the powdery diffusion particles 512 are added thereto, and after the two are mixed evenly, they are stretched at a certain temperature to form a film.

[0139] For another example, see Fig.14 , Fig.14 The structure diagram of the light-distributing member 50 provided in some other embodiments of the present application is shown in FIG. In this embodiment, the diffusion particles 512 are disposed on one surface of the substrate 511. This structure can be formed by coating the diffusion particles 512 on one surface of the substrate 511 using a coating process, and the processing difficulty of the light-distributing member body 51 is relatively low.

[0140] For more examples, see Fig.15 , Fig.15The schematic diagram of the structure of the light-distributing member 50 provided in some other embodiments of the present application. In this embodiment, the diffusion particles 512 are arranged on two opposite surfaces of the substrate 511. This structure can be formed by coating the diffusion particles 512 on two opposite surfaces of the substrate 511 using a coating process. The amount of the diffusion particles 512 in the light-distributing member body 51 is large, and the light-distributing effect is better.

[0141] After the ambient light a is incident on the light-distributing member 50 provided in any of the above embodiments through the light-transmitting window 10a, the ambient light a is incident on the light-distributing member 50 provided in any of the above embodiments. Fig.13 Under the action of the diffusion particles 512 in the light homogenizer body 51 of the light homogenizer 50, countless reflections, refractions and scatterings occur, thereby forming a more uniform surface light source in the light homogenizer body 51. The light emission angle of the surface light source after emitting from the light homogenizer body 51 will be significantly reduced, and will be emitted roughly directly below the light homogenizer body 51. In this way, the FOV of the ambient light sensor 30 located directly below can be increased.

[0142] The light averaging element 50 is Fig.13 Taking the light-distributing element 50 as an example, the above technical effect is verified by experiment. Fig.16 , Fig.16 for Figure 5 The graph of the light power of the light received by the ambient light sensor 30 changes with the incident angle of the light when the electronic device 100 has the light homogenizing element 50 and when the light homogenizing element 50 is not provided. The power of the incident light is maintained at 1 watt (W). It should be noted that in this embodiment and the following embodiments, when the incident angle is 0°, it means that the light is incident in a direction perpendicular to the photosensitive surface 31. Fig.16 It can be seen that the FOV of the ambient light sensor 30 is increased from about 60° to about 100° in the solution with the light homogenizer 50 compared to the solution without the light homogenizer 50. Because of the light homogenizer 50, even if the ambient light sensor 30 is sunk to the circuit board 20, it can still smoothly receive ambient light incident at a large angle from the outside. This ensures the light efficiency of the ambient light sensor 30 in receiving light, meets the detection requirements, and improves the detection accuracy.

[0143] In addition, based on the solution that the light-transmitting window 10a includes the first light-transmitting portion 10a2 of the display panel 12, the first light-transmitting portion 10a2 can emit light together with other portions of the display panel 12 to display images or videos when the screen is working.

[0144] On the basis of the above, the light incident on the light-evening element body 51 includes not only ambient light but also self-luminescence from the first light-transmitting part 10a2. This part of the self-luminescence will become more uniform after passing through the light-evening element body 51. Therefore, the ambient light sensor 30 will be more accurate in detecting the overall intensity of the self-luminescence of each pixel at different positions and different brightness on the first light-transmitting part 10a2, which is more conducive to the subsequent precise subtraction of the self-luminous part of the screen in the cutout algorithm, and is conducive to improving the accuracy of collecting external ambient light.

[0145] Furthermore, please see Fig.17 , Fig.17 for Figure 5 The graphs of the optical power of the three colors of received light of the ambient light sensor 30 versus the wavelength of the received light when the electronic device 100 has the light homogenizer 50 and does not have the light homogenizer 50 are shown. Among them, the red light R1, green light G1, and blue light B1 are three colors of light that have not been processed by the light homogenizer 50, and the red light R2, green light G2, and blue light B2 are three colors of light that have been processed by the light homogenizer 50. Fig.17 It can be seen that for the three colors of received light, the light homogenizer body 51 in the light homogenizer 50 has the function of reducing the atomic spectrum oscillation effect. This characteristic of the light homogenizer body 51 can effectively eliminate the peak oscillation burrs in the spectrum, which is conducive to the accurate detection of the ambient light color temperature by the ambient light sensor 30.

[0146] Furthermore, the light homogenizing element body 51 in the light homogenizing element 50 can also eliminate the light red shift or blue shift phenomenon caused by the difference in the angle of light received by the ambient light sensor 30, which is beneficial to improve the accuracy of ambient light detection.

[0147] In other embodiments, the light-distributing member body 51 may also be dark in color as a whole or in part. The dark color described in this embodiment and the following embodiments refers to a color with a light intensity (L value) less than 0. Specifically, the light-distributing member body 51 may be gray, dark gray, dark blue, dark brown, etc. The dark part has a lower light transmittance, which can reduce the visibility of the light-distributing member body 51 and improve the appearance of the surface component 10.

[0148] In order to obtain a light-homogenizing member body 51 that is dark in color in whole or in part, dark pigment particles may be added to the substrate 511 in whole or in part, or dark diffused ions may be provided to modulate the color of the light-homogenizing member body 51 in whole or in part to a dark color.

[0149] When the color of the light-homogenizing element body 51 is partially dark, please refer to Fig.18 , Fig.18The top view of the light homogenizer 50 provided in some embodiments of the present application, the light homogenizer body 51 includes a plurality of dark portions A, and the plurality of dark portions A are evenly distributed. When the color of a part of the light homogenizer body 51 is dark, the dark color may also be black. In this way, the visibility of the light homogenizer body 51 can also be reduced, and the appearance of the surface component 10 can be improved.

[0150] In order to reduce the visibility of the light homogenizing member body 51 and ensure the appearance of the surface component 10, other methods may be used.

[0151] For examples, see Fig.19 , Fig.19 The structure diagram of the light homogenizer 50 provided in some embodiments of the present application. In addition to the light homogenizer body 51, the light homogenizer 50 also includes a light shielding member 52. The light homogenizer body 51 can be the light homogenizer body 51 provided in any of the above embodiments. Fig.19 The light averaging element body 51 is Fig.13 The light-distributing member body 51 in the light-distributing member 50 is illustrated as an example, which cannot be considered as a special limitation of the present application. The light-shielding member 52 is arranged on the light-incident side of the light-distributing member body 51. Figure 5 In the electronic device 100 shown, the shading member 52 is disposed on a side of the light homogenizing member body 51 close to the first surface S1, that is, the shading member 52 and the first surface S1 are located on the same side of the light homogenizing member body 51. The shading member 52 can be disposed on a partial area of ​​the light incident surface of the light homogenizing member body 51, specifically, on a partial area of ​​the light incident surface of the light homogenizing member body 51 opposite to the light transmission window 10a, or on the entire area of ​​the light incident surface of the light homogenizing member body 51, which is not specifically limited herein.

[0152] The shading member 52 can reduce the visibility of the light-homogenizing member body 51 , thereby ensuring the appearance of the surface member 10 .

[0153] In some embodiments, the shading member 52 may include a dark light-transmitting film or a polarizing film. The dark light-transmitting film may be gray, dark blue, etc. The polarizing film includes but is not limited to a linear polarizing film and a circular polarizing film. This structure is simple, easy to manufacture, and has a better shading effect.

[0154] In some other embodiments, the light shielding member 52 may include a dark layer. The dark layer may be an ink layer or a dark tape, which is not specifically limited here. When the dark layer is ink, the dark layer may be provided on the light-distributing member body 51 by screen printing. The color of the dark layer may be black. At least one first through hole is provided on the dark layer. This structure is simple and convenient to manufacture.

[0155] Among them, the first through hole can be a circular hole, an elliptical hole, a square hole, a triangular hole, an elliptical hole, a rectangular hole, a polygonal hole, etc.

[0156] When the first through hole is a circular hole, the diameter of the first through hole may be greater than or equal to 10μm and less than or equal to 1mm. Specifically, the diameter of the first through hole may be 10μm, 20μm, 30μm, 40μm, 100μm, 200μm, 300μm, 400μm, 500μm, 600μm, 700μm, 800μm, 900μm or 1mm. When the first through hole is a square hole or a rectangular hole, the side length of the first through hole may be greater than or equal to 10μm and less than or equal to 1mm. Specifically, the side length of the first through hole may be 10μm, 20μm, 30μm, 40μm, 100μm, 200μm, 300μm, 400μm, 500μm, 600μm, 700μm, 800μm, 900μm or 1mm. In this way, the size of the first through hole is moderate, which can effectively reduce the visibility of the light homogenizing member 50 .

[0157] The number of the first through holes on the dark layer may be one or more. In some embodiments, the number of the first through holes is more than one, and the plurality of first through holes may be arrayed on the light shielding member 52. Specifically, the array of the plurality of first through holes on the light shielding member 52 includes but is not limited to a rectangular array, a circular array, or an elliptical array.

[0158] In order to verify the influence of different first through hole design modes on the FOV and light efficiency of the received light of the ambient light sensor 30, please refer to Fig. 20 , Fig. 20 The six light-distributing members 50 provided in some embodiments of the present application are top views. The six light-distributing members 50 are all in the shape of rectangular films, which include roughly rectangular films and absolutely rectangular films. The six light-distributing members 50 have the same long side size and the same short side size. The differences between the six light-distributing members 50 include: Fig. 20 The light homogenizing member 50 shown in (a) only includes a light homogenizing member body 51, and the color of the light homogenizing member body 51 is white; Fig. 20 The light-distributing member 50 shown in (b), (c), (d), (e), and (f) includes, in addition to a white light-distributing member body 51, a light-shielding member 52. The light-shielding member 52 includes a dark layer, and a plurality of first through holes 52a are arrayed on the dark layer.

[0159] Fig. 20 The first through holes 52a in the light-distributing member 50 shown in (b) and (c) are both rectangular holes, the long side extension direction of the rectangular hole is roughly consistent with the long side extension direction of the light-distributing member 50, and the short side extension direction of the rectangular hole is roughly consistent with the short side extension direction of the light-distributing member 50.

[0160] Fig. 20 The array of the first through holes 52a in the light averaging member 50 shown in (b) and (c) is a rectangular array, but Fig. 20 The arrangement density of the first through holes 52a in the light averaging member 50 shown in (b) is less than Fig. 20 (c) shows the arrangement density of the first through holes 52a in the light homogenizing member 50.

[0161] Fig. 20 In the light homogenizing member 50 shown in (d), the first through holes 52a are square holes, and the array of the first through holes 52a is a rectangular array.

[0162] Fig. 20 The first through holes 52a in the light-distributing member 50 shown in (e) and (f) are both circular holes, except that: Fig. 20 The array of the first through holes 52a in the light-distributing member 50 shown in (e) is a rectangular array. Fig. 20 The array of the first through holes 52a in the light-distributing member 50 shown in (f) is an elliptical array. Specifically, Fig. 20 As shown in (f) in FIG. 1 , the long axis of the elliptical array trajectory of the first through hole 52a in the light homogenizer 50 is parallel to the long side of the light homogenizer 50, and the short axis of the elliptical array trajectory is parallel to the short side of the light homogenizer 50. The long side of the light homogenizer 50 refers to the longer side of the two adjacent sides of the light homogenizer 50, and the short side of the light homogenizer 50 refers to the shorter side of the two adjacent sides of the light homogenizer 50. Fig. 20 In (f) of the diagram, the density of the first through holes 52a arranged on the dark layer of the light equalizer 50 opposite to the middle part of the light equalizer body 51 is relatively small, while the density of the first through holes 52a arranged on the dark layer of the light equalizer body 51 opposite to the edge part of the light equalizer body 51 is relatively large.

[0163] The length of the light-transmitting window 10a is 5 mm and the width is 1 mm. Figure 5 When in the electronic device 100 shown, the light homogenizer 50 completely covers the light-transmitting window 10a, and the long side extension direction of the light homogenizer 50 is consistent with the long side extension direction of the light-transmitting window 10a, and the short side extension direction of the light homogenizer 50 is consistent with the short side extension direction of the light-transmitting window 10a. The distance H1 from the light homogenizer 50 to the ambient light sensor 30 is 0.845 mm, and the distance H2 from the light homogenizer 50 to the display panel 12 is 0.3 mm. The power of the incident light is maintained at 1 (in W).

[0164] The received light power (in W), light efficiency (in %), central light intensity (in W / sr), and FOV (in °) of the ambient light sensor 30 in the electronic device 100 obtained from the experiment are recorded in Table 1 below.

[0165] Table 1

[0166]

[0167] Among them, it should be noted that in Table 1 and the following tables, "H" represents the horizontal direction, that is, the X-axis direction; "V" represents the vertical direction, that is, the Y-axis direction; "H+" represents the direction inclined to the +X-axis direction (that is, the direction of the arrow of the X-axis) relative to the 0° direction; "H-" represents the direction inclined to the -X-axis direction (that is, the opposite direction of the arrow of the X-axis) relative to the 0° direction; "V+" represents the direction inclined to the +Y-axis direction (that is, the direction of the arrow of the Y-axis) relative to the 0° direction; "V-" represents the direction inclined to the -Y-axis direction (that is, the opposite direction of the arrow of the Y-axis) relative to the 0° direction.

[0168] It can be seen from Table 1 above that, compared with the light-distributing member 50 shown in (a), the other five light-distributing members 50 provided with the light-shielding member 52 significantly reduce the light efficiency of the ambient light sensor 30, reduce the visibility, and the front appearance of the surface component 10 is better. At the same time, the light-distributing members 50 shown in (b), (c), (d), (e), and (f) also make the FOV of the ambient light sensor 30 better, meeting the use requirements.

[0169] The size of the light homogenizing member 50 and the distance between the light homogenizing member 50 and the light-transmitting window 10 a and the photosensitive surface 31 are described below.

[0170] In some embodiments, the thickness of the light-distributing member body 51 in the light-distributing member 50 may be greater than or equal to 0.01 mm, and less than or equal to 0.3 mm. Specifically, the thickness of the light-distributing member 50 may be 0.01 mm, 0.07 mm, 0.1 mm, 0.12 mm, 0.2 mm or 0.3 mm. When the thickness of the light-distributing member 50 is within this range, the thickness of the light-distributing member 50 is relatively small, which is conducive to the thinning of the thickness of the electronic device 100. Moreover, the reflectivity of the light is low and the transmittance is high, which can reduce the visibility of the light-distributing member 50 and improve the light efficiency and FOV of the received light of the ambient light sensor 30.

[0171] In order to verify the above conclusion, four types of light homogenizers 50 are selected for experiments. The thickness of the light homogenizer body 51 in the four types of light homogenizers 50 is within the above thickness range.

[0172] For details, please refer to Fig.21 , Fig.21 For the simulation experiment, four types of light averaging components 50 are respectively used in Figure 5 The light transmittance (T) and reflectance (R) of the electronic device shown in the figure change with the incident angle of the light. Specifically, Fig.21 (a) is the light averaging element 50 of model 1 when applied to Figure 5The graph of light transmittance and reflectivity of the electronic device shown in FIG. 1 varies with the incident angle of the light. Fig.21 (b) is the light averaging element 50 of model 2 when applied to Figure 5 The graph of light transmittance and reflectivity of the electronic device shown in FIG. 1 varies with the incident angle of the light. Fig.21 (c) is the light averaging element 50 of model 3 when applied to Figure 5 The curve of light transmittance and reflectivity of the electronic device shown in the figure changes with the incident angle of the light. Fig.21 (d) is the light averaging element 50 of model 4 when applied to Figure 5 The graph of light transmittance and reflectivity of the electronic device shown in FIG. 1 varies with the incident angle of the light.

[0173] The above four types of light averaging components 50 are all Fig.13 The structures of the light homogenizer 50 shown are the same, the thickness of the light homogenizer body 51 in the light homogenizer 50 of model 1 is 0.12 mm, the thickness of the light homogenizer body 51 in the light homogenizer 50 of model 2 is 0.1 mm, the thickness of the light homogenizer body 51 in the light homogenizer 50 of model 3 is 0.07 mm, and the thickness of the light homogenizer body 51 in the light homogenizer 50 of model 4 is 0.1 mm. The density of the diffusion particles 512 in the light homogenizer 50 of model 4 is different from the density of the diffusion particles 512 in the light homogenizer 50 of model 2.

[0174] Experimental parameters: The length of the light-transmitting window 10a is 5 mm, and the width is 1 mm. The light-distributing member 50 completely covers the light-transmitting window 10a. The distance H1 from the light-distributing member 50 to the ambient light sensor 30 is 0.845 mm, and the distance H2 from the light-distributing member 50 to the display panel 12 is 0.3 mm. The power of the incident light is kept at 1 (in W).

[0175] from Fig.21 It can be seen that when light is incident from various angles, the reflectivity of the light homogenizer 50 described in Model 1 to Model 4 is lower than the transmittance, thereby reducing the visibility of the light homogenizer 50 and improving the light efficiency and FOV of the ambient light sensor 30 receiving light.

[0176] Meanwhile, the received light power (in W), light efficiency (in %), central light intensity (in W / sr) and FOV (in °) of the ambient light sensors 30 in the four electronic devices obtained by the simulation experiment are recorded in the following Table 2. The four electronic devices are the electronic devices respectively including the four types of light averaging elements 50 mentioned above.

[0177] Table 2

[0178]

[0179] It can be seen from Table 2 that the light efficiency and FOV of the ambient light sensors 30 in the four electronic devices 100 are relatively good, which can improve the detection accuracy of the ambient light sensors 30. At the same time, the thickness of the light equalizer body 51 is relatively small, which is conducive to the thickness reduction of the electronic device 100.

[0180] In some embodiments, please refer back to Figure 5 , the distance H1 from the light-distributing member body 51 in the light-distributing member 50 to the ambient light sensor 30 can be greater than or equal to 0 mm, and less than or equal to 5 mm. Specifically, the distance H1 can be 0 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.845 mm, 1 mm, 2 mm, 3 mm, 4 mm or 5 mm. In this way, the distance H1 from the light-distributing member body 51 to the ambient light sensor 30 is moderate, and the central light intensity and optical power of the received light of the ambient light sensor 30 are large, which can improve the detection accuracy of the ambient light sensor 30 and is conducive to the thin design of the electronic device 100.

[0181] In order to verify the above conclusion, the range of 0 to 0.845 mm within the range of the above distance H1 is selected for experiment.

[0182] For details, please refer to Fig. 22 and Fig.23 , Fig. 22 The simulation results are obtained Figure 5 The central light intensity of the received light of the ambient light sensor 30 in the electronic device 100 changes with the moving distance. Fig.23 The simulation results are obtained Figure 5 The graph shows how the optical power of the received light of the ambient light sensor 30 in the electronic device 100 changes with the moving distance.

[0183] The moving distance refers to the distance that the light homogenizer 50 moves toward the ambient light sensor 30 from the initial position of distance H1=0.845 mm (i.e., the moving distance is 0 mm). When the moving distance is 0.845 mm, the light homogenizer 50 contacts the ambient light sensor 30. In other words, the moving distance is the difference between 0.845 mm and the distance H1.

[0184] Experimental parameters: The length of the light-transmitting window 10a is 5 mm, and the width is 1 mm. The light-distributing member 50 completely covers the light-transmitting window 10a. The light-distributing member 50 is the light-distributing member 50 described in the above-mentioned model 3, and the distance H2 from the light-distributing member 50 to the display panel 12 is maintained at 0.3 mm. The power of the incident light is maintained at 1 (in W).

[0185] Depend on Fig. 22 and Fig.23It can be seen that as the moving distance increases, the distance H1 gradually decreases, and the central light intensity and optical power of the received light of the ambient light sensor 30 gradually increase. When the distance H1 is in the range of 0 to 0.845 mm, the central light intensity of the received light of the ambient light sensor 30 is between 0.0003 W / sr and 0.0006 W / sr, and the optical power of the received light of the ambient light sensor 30 is between 0.0006 W and 0.0013 W. Therefore, the central light intensity and optical power are relatively large, which is conducive to improving the detection accuracy of the ambient light sensor 30.

[0186] When the moving distance is 0.845mm, the distance H1 is 0mm. At this time, the received light power (in W), light efficiency (in %), central light intensity (in W / sr) and FOV (in °) of the ambient light sensor 30 in the electronic device 100 obtained from the experiment are recorded in Table 3 below.

[0187] Table 3

[0188]

[0189] It can be seen from Table 3 above that, compared with the solution with a distance H1 of 0.845 mm (as shown in the column of Model 3 in Table 2 above), when the distance H1 is 0 mm, the center intensity and light efficiency are both increased by 1 times. However, the FOV of the ambient light sensor 30 does not change significantly. It can be seen that, when the ambient light sensor 30 is arranged on the circuit board 20, although the distance H1 between the ambient light sensor 30 and the light homogenizing member 50 is increased, due to the effect of the light homogenizing member 50, the FOV of the ambient light sensor 30 receiving light can still be maintained in a larger range.

[0190] In some embodiments, please refer back to Figure 5 , the distance H2 from the light-distributing member body 51 in the light-distributing member 50 to the display panel 12 can be greater than or equal to 0 mm, and less than or equal to 1 mm. Specifically, the distance H2 can be 0 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm. In this way, the distance H2 from the light-distributing member body 51 to the display panel 12 is moderate, which can take into account the visibility of the light-distributing member 50 and the optical power and FOV of the received light of the ambient light sensor 30.

[0191] In order to verify the above conclusion, the range of 0 to 0.5 mm within the range of the above distance H2 is selected for experiment.

[0192] See also Fig.24 and Fig.25 , Fig.24 The simulation results are obtained Figure 5The electronic device 100 is shown as a curve diagram showing a change in the reflected light power of the light averaging element 50 with respect to the distance H2 when the incident angle of the light is 0°. Fig.25 The simulation results are obtained Figure 5 The electronic device 100 is shown as a curve diagram showing a change in the reflected light power of the light homogenizing element 50 as a function of the distance H2 when the incident angle of the light is 20°.

[0193] Experimental parameters: The length of the light-transmitting window 10a is 5 mm, and the width is 1 mm. The light-distributing member 50 completely covers the light-transmitting window 10a. The light-distributing member 50 is the light-distributing member 50 described in the above-mentioned model 3, and the distance H1 between the light-distributing member 50 and the ambient light sensor 30 is 0.845 mm. The power of the incident light is kept at 1 (in W).

[0194] Depend on Fig.24 and Fig.25 It can be seen that as the distance H2 gradually increases, the reflected light power gradually decreases and the visibility gradually decreases. When the distance H2 is within the range of 0 to 0.5 mm, the reflected light power basically meets the use requirements.

[0195] When the distance H2 is 0.5 mm, the received light power (in W), light efficiency (in %), central light intensity (in W / sr) and FOV (in °) of the ambient light sensor 30 in the electronic device 100 are recorded in Table 4 below.

[0196] Table 4

[0197]

[0198] It can be seen from Table 4 that, compared with the solution where the distance H2 is 0.3 mm (as shown in the column of Model 3 in Table 2 above), when the distance H2 is 0.5 mm, the optical efficiency and FOV of the received light of the ambient light sensor 30 are reduced, but still meet the detection requirements of the ambient light sensor 30. Therefore, when the distance H2 is within the range of 0 to 0.5 mm, the visibility of the light homogenizing member 50 and the optical power and FOV of the received light of the ambient light sensor 30 can be taken into account at the same time.

[0199] Factors that affect the optical power and FOV of the received light of the ambient light sensor 30 include not only the thickness of the light homogenizer body 51 in the light homogenizer 50 , the distance H1 , and the distance H2 , but also the size of the light-transmitting window 10 a .

[0200] In some embodiments, the length of the light-transmitting window 10a is greater than or equal to 0.5 mm and less than or equal to 10 mm, and the width is greater than or equal to 0.5 mm and less than or equal to 10 mm. Specifically, the length of the light-transmitting window 10a can be 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, and the width can be 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm. When the size of the light-transmitting window 10a is within this range, the optical power and FOV of the received light of the ambient light sensor 30 are better, and can meet the detection requirements of the ambient light sensor 30.

[0201] In order to verify the above conclusion, the following experiment is conducted on the width of the light-transmitting window 10a, which is within the above width range of 1 mm to 2 mm.

[0202] For details, please refer to Fig.26 , Fig.26 The simulation results are obtained Figure 5 The FOV of the ambient light sensor 30 in the electronic device 100 shown in FIG. 1 varies with the width of the light-transmitting window 10a. Specifically, Fig.26 (a) is a curve diagram showing the change of the FOV of the ambient light sensor 30 in the V+ direction with the width of the light-transmitting window 10a. Fig.26 (b) is a curve diagram showing the change of the FOV of the received light of the ambient light sensor 30 in the V-direction with the width of the light-transmitting window 10a. Fig.26 (c) is a curve diagram showing the change of the FOV full angle of the received light of the ambient light sensor 30 in the horizontal direction (ie, the V direction) with the width of the light-transmitting window 10a. Fig.26 (d) is a curve diagram showing the variation of the FOV full angle of the received light of the ambient light sensor 30 in the vertical direction (ie, the H direction) with the width of the light-transmitting window 10a.

[0203] Experimental parameters: The length of the light-transmitting window 10a is 5 mm. The light-distributing member 50 completely covers the light-transmitting window 10a. The light-distributing member 50 is the light-distributing member 50 described in the above-mentioned model 3. The distance H1 from the light-distributing member 50 to the ambient light sensor 30 is 0.845 mm, and the distance H2 from the light-distributing member 50 to the display panel 12 is maintained at 0.3 mm. The power of the incident light is maintained at 1 (in W).

[0204] Depend on Fig.26 It can be seen that when the wide side length of the light-transmitting window 10 a is in the range of 1 mm to 2 mm, the FOV of the received light of the ambient light sensor 30 in the V direction and the H direction are both better, meeting the detection requirements of the ambient light sensor 30 .

[0205] When the width of the light-transmitting window 10a is 2 mm, the received light power (in W), light efficiency (in %) and central light intensity (in W / sr) of the ambient light sensor 30 in the electronic device 100 are recorded in Table 5 below.

[0206] Table 5

[0207] Incident light power 1 Received optical power 0.001211158 Light Efficiency 0.1211158 Central light intensity 0.0005635683

[0208] It can be seen from Table 5 that, compared with the solution in which the wide side length of the light-transmitting window 10a is 1 mm (as shown in the column of Model 3 in Table 2 above), when the wide side length of the light-transmitting window 10a is 2 mm, the optical efficiency of the received light of the ambient light sensor 30 increases. Therefore, when the wide side length of the light-transmitting window 10a is within the range of 1 mm-2 mm, the optical power of the received light of the ambient light sensor 30 can be maintained at a relatively good level.

[0209] The other structural components of the electronic device 100 are introduced below.

[0210] Please return to Figure 1 The smart watch includes a watch body and a watch strap 8. The watch body is also Figure 2 The main body shown, in addition to the above-mentioned structure, also includes a shell 90, which can include a watch body 91, an upper watch case 92, a lower watch case 93 and a battery (not shown in the figure), etc.

[0211] The watch body 91 is the support frame of the watch body. The material of the watch body 91 can be stainless steel to ensure the structural strength of the watch body 91 and the support strength for other components.

[0212] The upper case 92 is connected to one end of the body 91 along the Z axis, and the lower case 93 is connected to the other end of the body 91 along the Z axis. The materials of the upper case 92 and the lower case 93 include but are not limited to metal materials such as stainless steel and plastics such as polycarbonate (PC), PC+glass fiber, and ABS plastic (acrylonitrile butadiene styrene plastic).

[0213] The upper case 92 , the body 91 and the lower case 93 form a receiving cavity, and the receiving cavity receives the circuit board 20 , the ambient light sensor 30 and the light equalizing member 50 .

[0214] Please continue reading Figure 1The watchband 8 may include a first watchband portion 81 and a second watchband portion 82. One end of the first watchband portion 81 and one end of the second watchband portion 82 are connected to opposite ends of the watch body. A first locking portion 811 is provided at the other end of the first watchband portion 81, and a second locking portion 821 is provided at the other end of the second watchband portion 82. The first locking portion 811 and the second locking portion 821 are detachably locked to each other so that the watch body can be worn on a human wrist.

[0215] Among them, the matching structure composed of the first locking part 811 and the second locking part 821 can be a buckle structure such as a hook buckle, a concealed buckle, a butterfly buckle, a belt snap buckle, a folding safety buckle, a folding buckle or a pin buckle, and the present application does not make specific limitations on this.

[0216] The above embodiments are exemplified by taking the electronic device 100 as a smart watch. In some other embodiments, the electronic device 100 may also be other devices.

[0217] For examples, see Fig. 27 and Fig.28 , Fig. 27 This is a front view of an electronic device 100 provided in some embodiments of the present application. Fig.28 for Fig. 27 Schematic diagram of the cross-sectional structure at line BB.

[0218] The surface component 10 in the electronic device 100 is still a screen. In addition to the screen, the electronic device 100 also includes a middle frame 101 and a back cover 102. The screen, the middle frame 101 and the back cover 102 are connected in sequence. A receiving cavity is provided between the middle frame 101 and the back cover 102, and the circuit board 20 and the ambient light sensor 30 are received in the receiving cavity. On this basis, the screen and the light-distributing member 50 are located on the side of the middle frame 101 that is opposite to the receiving cavity. In other words, the screen and the light-distributing member 50 are located on one side of the middle frame 101, and the circuit board 20 and the ambient light sensor 30 are located on the other side of the middle frame 101.

[0219] On the basis of the above, a light hole 101 a is provided in the portion of the middle frame 101 between the light homogenizing member 50 and the photosensitive surface 31 , so that light from the light homogenizing member 50 can be transmitted to the photosensitive surface 31 .

[0220] In this way, the ambient light sensor 30 is sunk onto the circuit board 20 without the need for an adapter structure to transfer, which can reduce the structural complexity of the electronic device 100, save costs, and save the internal space of the electronic device, which is conducive to the thinning and miniaturization of the electronic device 100, and optimizes the internal space layout of the electronic device. Moreover, the ambient light sensor 30 occupies a small area on the circuit board 20, and the utilization rate of the circuit board 20 is high.
