[0002] The present application relates to the field of electronic technology, and in particular to an electronic device, a screen brightness control method and a light guide structure. Background Art

[0003] At present, photosensitive devices such as ambient light sensors are widely used in electronic devices such as mobile phones and tablet computers. In addition, with the development of electronic device technology, users have higher and higher requirements for full-screen and thin electronic devices. In the related art, the structure of photosensitive devices inside electronic devices is partially not conducive to the full-screen and thin design of electronic devices, and further improvement is needed. Summary of the invention

[0004] The present application provides an electronic device, a screen brightness control method and a light-guiding structure. When the light-guiding structure is applied to the electronic device, the light-guiding performance of the light-guiding structure can be used to guide the ambient light in the external environment where the electronic device is located to the photosensitive surface of the photosensitive device. There is no need to open a light hole on the screen, nor is there a need to set the photosensitive device upright on the circuit board, which is beneficial to taking into account both the thinness and full-screen nature of the electronic device.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, the present application provides an electronic device, comprising: a frame, a screen, a photosensitive device and a light-guiding structure; the frame surrounds the screen, the frame has a through hole, and the through hole penetrates the frame in the direction from the inner peripheral surface of the frame to the outer peripheral surface of the frame; the photosensitive device includes a photosensitive surface, and the photosensitive surface faces the screen; the light-guiding structure includes a light-guiding column and a light-guiding member, and the light-guiding member is connected to the light-guiding column. The light-guiding column is arranged in the through hole, and the light-guiding column has a light-incident surface located at the through hole. Along the thickness direction of the screen, the light-guiding member is located at one end of the light-guiding column adjacent to the screen, and the light-guiding member includes a light-emitting surface, and in a plane parallel to the screen, the orthographic projection of the photosensitive surface and the orthographic projection of the light-emitting surface at least partially overlap.

[0007] According to the electronic device of the embodiment of the present application, on the one hand, the ambient light in the external environment where the electronic device is located can be incident on the light-guiding structure through the light-incident surface, and the ambient light can be emitted through the light-emitting surface under the guidance of the light-guiding structure. Since in a plane parallel to the screen, the orthographic projection of the photosensitive surface of the photosensitive device and the orthographic projection of the light-emitting surface of the light-guiding component at least partially overlap. Therefore, the ambient light emitted through the light-emitting surface can be directed toward the photosensitive surface and sensed by the photosensitive device, thereby realizing the detection of ambient light by the photosensitive device. In this way, there is no need to open a light hole on the screen, which is conducive to improving the structural strength of the screen and the full-screen design of the screen. On the other hand, although a light guide is provided between the screen and the photosensitive device, the thickness direction of the photosensitive device is consistent with the thickness direction of the screen because the photosensitive surface faces the screen, so the size of the light guide and the photosensitive device as a whole in the thickness direction of the screen is greatly reduced compared with the photosensitive device being provided vertically on the circuit board; further, since the light guide is located at one end of the light guide column adjacent to the screen along the thickness direction of the screen, that is, the position where the light guide is provided is close to the screen and the middle frame, more accommodation space can be created for the photosensitive device while the thickness of the electronic device remains unchanged, further making the layout of the electronic device more compact, thereby facilitating the reduction of the thickness of the electronic device and realizing the thin design of the electronic device. In addition, compared with not providing a light guide column, providing the light guide column through the through hole is conducive to smoothly guiding more light outside the electronic device to the light guide, increasing the field angle of the photosensitive device receiving external light, thereby improving the accuracy of the photosensitive device in detecting external ambient light.

[0008] In short, the electronic device in the embodiment of the present application can take into account both the thinness and full-screen nature of the electronic device, while improving the structural strength of the electronic device.

[0009] In some examples, the light guide is in sheet form, so that the light guide is stacked between the screen and the photosensitive device, thereby further reducing the thickness space occupied by the light guide and the photosensitive device as a whole, thereby facilitating the reduction of the thickness of the electronic device and achieving a thin design of the electronic device.

[0010] In some embodiments of the first aspect of the present application, the frame is connected to the screen, thereby improving the fixing strength of the screen.

[0011] In some embodiments of the first aspect of the present application, the electronic device further comprises a circuit board, which is located in the frame and fixed relative to the frame. The end of the photosensitive device in its thickness direction away from the screen is fixed to the surface of the circuit board facing the screen.

[0012] In some embodiments of the first aspect of the present application, since the photosensitive device is arranged on the circuit board and is located within the range surrounded by the outer edge of the circuit board, the distance between the photosensitive device and the through hole in the direction parallel to the screen is relatively far. In order to take into account the connection between the light guide column and the light guide plate, and at the same time prevent the light emitting surface on the light guide from being too close to the center of the middle plate in order to be opposite to the light sensitive surface, thereby causing the size of the light guide in the arrangement direction of the light guide column to be too large and occupying too much space inside the electronic device, in a plane parallel to the screen, a part of the orthographic projection of the photosensitive surface close to the light guide column is a first projection, and a part of the orthographic projection of the light emitting surface away from the light guide column is a second projection, and the first projection overlaps with the second projection to form an overlapping area.

[0013] Specifically, in order to facilitate the ambient light emitted from the light-emitting surface to cover the photosensitive surface as much as possible so as to be sensed by the photosensitive surface, thereby improving the reliability of the photosensitive device in detecting ambient light, in a plane F parallel to the screen, the ratio of the area of ​​the overlapping area to the area of ​​the orthographic projection of the light-emitting surface is in the range of greater than or equal to 0.6 and less than 1.

[0014] Specifically, in order to facilitate the ambient light emitted from the light-emitting surface to cover the photosensitive surface as much as possible so as to be sensed by the photosensitive surface, thereby improving the reliability of the photosensitive device in detecting the light intensity of the ambient light, in a plane parallel to the screen, the ratio of the area of ​​the overlapping area to the area of ​​the orthographic projection of the photosensitive surface is in the range of greater than or equal to 0.6 and less than 1.

[0015] In some embodiments of the first aspect of the present application, in order to facilitate the ambient light emitted from the light-emitting surface to cover the photosensitive surface as much as possible so as to be sensed by the photosensitive surface, thereby improving the reliability of the photosensitive device in detecting the light intensity of the ambient light, the orthographic projection of the photosensitive surface is located within the orthographic projection of the light-emitting surface in a plane parallel to the screen.

[0016] Specifically, in order to allow the ambient light emitted from the light-emitting surface to cover the photosensitive surface as much as possible so as to be sensed by the photosensitive surface, while preventing the light guide from occupying too much space inside the electronic device due to the light-emitting surface being designed to be too large, the distance between the edge of the orthographic projection of the photosensitive surface and the edge of the orthographic projection of the light-emitting surface in a plane parallel to the screen has a value range of greater than 0 and less than or equal to 1.5 mm.

[0017] Specifically, in order to facilitate as much ambient light emitted from the light-emitting surface as possible to be directed to the photosensitive surface so as to be sensed by the photosensitive surface, thereby improving the reliability of the photosensitive device in detecting the intensity of ambient light, in a plane F parallel to the screen, the center of the orthographic projection of the photosensitive surface coincides with the center of the orthographic projection of the light-emitting surface.

[0018] In some embodiments of the first aspect of the present application, in the direction from the light guide to the light guide column, the end of the light guide column away from the light guide is inclined toward the screen. In this way, the light incident surface can be closer to the display surface of the screen, so that the light intensity of the ambient light incident on the light incident surface is closer to the ambient light intensity between the user and the screen, thereby making the light intensity closer to the light intensity of the user's eyes, thereby improving the accuracy of the light intensity detection of the ambient light by the photosensitive device.

[0019] In some embodiments of the first aspect of the present application, the light emitting surface is arranged parallel to the screen, and the angle between the central axis of the light guide column and the light emitting surface is greater than or equal to 10°. In this way, the light incident surface can be closer to the display surface of the screen, so that the light intensity of the ambient light incident on the light incident surface is closer to the ambient light intensity between the user and the screen, thereby making the light intensity closer to the light intensity of the user's eyes, thereby improving the accuracy of the light intensity detection of the ambient light by the photosensitive device.

[0020] Taking into account the difficulty of processing the through hole and the overall structural layout of the electronic device, the angle between the central axis of the light guide column and the light emitting surface is in the range of greater than or equal to 10° and less than 45°.

[0021] In some embodiments of the first aspect of the present application, in order to facilitate the ambient light emitted from the light-emitting surface to cover the photosensitive surface as much as possible so as to be sensed by the photosensitive surface, while taking into account the thin design of the electronic device, the photosensitive surface is arranged parallel to the light-emitting surface.

[0022] In some embodiments of the first aspect of the present application, in order to facilitate the ambient light emitted from the light-emitting surface to cover the photosensitive surface as much as possible so as to be sensed by the photosensitive surface, while taking into account the thin design of the electronic device, the distance between the photosensitive surface and the light-emitting surface is in the range of 0.2 to 0.6 mm.

[0023] In some embodiments of the first aspect of the present application, the roughness of the light incident surface is smaller than the roughness of the light emitting surface. In this way, on the one hand, it is beneficial to set the roughness of the light incident surface to be smaller, thereby improving the appearance and touch feel of the light incident surface; on the other hand, it is beneficial to set the roughness of the light emitting surface to be larger, thereby improving the scattering effect of the ambient light when the ambient light is emitted through the light emitting surface, and then more ambient light is emitted to the photosensitive device, thereby improving the reliability of the photosensitive device in detecting ambient light.

[0024] For example, the light guide column and the light guide member can be connected into an integrally formed member by injection molding, which is beneficial to improving the structural strength of the light guide column and the light guide member, simplifying the processing technology of the light guide structure, and reducing the processing cost of the light guide structure.

[0025] In some embodiments of the first aspect of the present application, the thickness of the light guide at the light emitting surface is in the range of 0.2 to 0.6 mm. In this way, on the one hand, it can prevent the thickness of the light guide at the light emitting surface from being too large and causing interference with the photosensitive device, and on the other hand, it can also prevent the thickness of the light guide at the light emitting surface from being too small and affecting the light guiding effect of the light guide.

[0026] Exemplarily, the thickness of the light guide at the position of the light emitting surface is 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, or 0.55 mm.

[0027] In some embodiments of the first aspect of the present application, the photosensitive device is located at one end of the circuit board adjacent to the through hole. No other electronic components are arranged in the area between the photosensitive device and the through hole on the circuit board. This is conducive to reducing the size of the light guide in the arrangement direction of the photosensitive device and the through hole, thereby saving material costs and reducing the space occupied by the light guide inside the electronic device.

[0028] In some embodiments of the first aspect of the present application, the electronic device further comprises a protective member. The protective member is located at the periphery of the photosensitive device and is located on the same side of the circuit board as the photosensitive device, and the height of the protective member protruding from the circuit board is greater than the height of the photosensitive device protruding from the circuit board. Thus, the protective member can be used to protect the photosensitive device, and the setting of the protective member will not affect the photosensitive device receiving ambient light.

[0029] Exemplarily, the material of the protective element is metal or plastic.

[0030] In some embodiments of the first aspect of the present application, the surface of the light guide facing the photosensitive device has an escape groove for evading the protective member, and the escape groove is located at the periphery of the light-emitting surface. In this way, on the one hand, the escape groove can be used to evade the protective member, so that the end of the protective member adjacent to the screen can be accommodated in the escape groove, solving the problem of the protective member being thickened due to protruding from the photosensitive device. On the other hand, it is helpful to ensure the thickness of the light guide at the position corresponding to the light-emitting surface, thereby improving the light-guiding effect of the light guide and facilitating more ambient light to be directed to the photosensitive surface.

[0031] In some embodiments of the first aspect of the present application, the light guide comprises a light guide sheet and a protrusion, the protrusion is arranged on the surface of the light guide sheet facing the photosensitive device, an end surface of the protrusion away from the light guide sheet forms a light emitting surface, and a side surface of the protrusion and the surface of the light guide sheet facing the photosensitive device jointly define an avoidance groove. The structure is simple.

[0032] In some embodiments of the first aspect of the present application, in order to seal the gap between the light guide column and the through hole to improve the dustproof and waterproof performance of the electronic device, a sealing structure is provided between the light guide column and the inner circumference of the through hole. The sealing structure can seal the gap between the light guide column and the inner circumference of the through hole, thereby improving the dustproof and waterproof effect of the electronic device.

[0033] Specifically, the sealing structure may be a sealant. Exemplarily, the sealant may be disposed between the light guide column and the inner peripheral surface of the through hole by a dispensing process. In other examples, the sealing structure may also be a rubber ring or a silicone ring.

[0034] In some embodiments of the first aspect of the present application, the light guide structure further includes a light guide connector, the light guide connector is laminated and fixed on the inner circumference of the frame, the light guide column is fixed on the surface of the light guide connector facing the frame, the light guide is fixed to one end of the light guide connector adjacent to the screen, the side surface of the light guide connector facing away from the light guide column is connected to the light emitting surface, and an annular sealing portion is provided between the light guide connector and the inner circumference of the frame, and the sealing portion is arranged around the light guide column. In this way, the sealing portion can be used to seal the gap between the through hole and the light guide column, thereby improving the dustproof and water-repellent effect of the electronic device.

[0035] Exemplarily, the light-guiding connecting member is in the form of a sheet.

[0036] On this basis, in order to prevent the light guide connector from occupying the space inside the electronic device, a clearance groove is provided on the inner circumference of the frame. The opening of one end of the through hole adjacent to the inside of the back shell is located at the bottom wall of the clearance groove. The light guide connector is located in the clearance groove.

[0037] In some embodiments of the first aspect of the present application, the roughness of the surface of the light-guiding connector facing away from the light-guiding column is greater than the roughness of the light-entering surface, and is equal to the roughness of the light-emitting surface. In this way, the roughness of the surface of the light-guiding connector facing away from the light-guiding column can be set relatively high, so when the ambient light is transmitted to the light-guiding connector via the light-guiding column, it is helpful to improve the scattering effect of the ambient light on the surface of the light-guiding connector facing the inside of the electronic device, so that more ambient light can be guided to the light-guiding component, thereby improving the intensity of the ambient light emitted from the light-emitting surface of the light-guiding component to the photosensitive surface.

[0038] Exemplarily, the sealing portion may be a sealant. Exemplarily, the sealant may be disposed between the sealing positioning area and the inner peripheral surface of the frame by a dispensing process. Another exemplary embodiment, the sealant may also be a backing adhesive. In other examples, the sealing portion may also be a rubber ring or a silicone ring.

[0039] In some embodiments of the first aspect of the present application, among the surfaces of the light-guiding structure, except for the light-emitting surface and the surface on one side of the light-guiding connector that faces away from the light-guiding column, the roughness of the remaining surfaces is less than the roughness of the light-emitting surface. In this way, when external ambient light enters the light-guiding structure through the light-entering surface, the remaining surfaces except the light-entering surface have a certain reflective effect, which can reduce the ambient light emitted from these surfaces, thereby facilitating more ambient light to be directed to the light-emitting surface, and then from the light-emitting surface to the photosensitive surface, thereby improving the reliability of the photosensitive device in detecting ambient light.

[0040] Exemplarily, the width of the sealing portion is 0.5 mm to 1.5 mm.

[0041] Exemplarily, the width of the sealing positioning area is 0.8 mm to 1.8 mm.

[0042] In some embodiments of the first aspect of the present application, the light guide structure is an integral injection molded part, so that the processing technology is simple.

[0043] In some embodiments of the first aspect of the present application, the light-guiding structure includes a light-transmitting matrix and diffusion particles, and the diffusion particles are evenly distributed in the light-transmitting matrix. In this way, the ambient light entering the light-guiding structure through the light-incident surface will produce scattering, reflection, and refraction when it is directed toward the diffusion particles, which is conducive to directing more ambient light to the light-emitting surface, thereby increasing the intensity of the ambient light emitted from the light-emitting surface to the photosensitive surface, and increasing the field of view of the photosensitive device and the light-guiding structure as a whole.

[0044] Exemplarily, the field of view angle ranges from 34° to 50°.

[0045] Exemplarily, the material of the light-transmitting substrate includes one or more of polycarbonate, polymethyl methacrylate, a blend of polystyrene and methyl methacrylate, and polystyrene. The material of the diffusion particles includes one or more of polycarbonate, polymethyl methacrylate, a blend of polystyrene and methyl methacrylate, polystyrene, silicon oxide, silicon, melamine, calcium carbonate, Teflon, titanium dioxide, and silicon dioxide.

[0046] For example, in 100 parts by weight of the light guide structure, the weight of the diffusion particles is 40 to 60 parts. In this way, the ambient light entering the light guide structure through the light incident surface will produce scattering, reflection, and refraction when it is directed to the diffusion particles, which is conducive to directing more ambient light to the light emitting surface, thereby increasing the intensity of the ambient light emitted from the light emitting surface to the photosensitive surface.

[0047] In some embodiments of the first aspect of the present application, the transmittance of the light guide structure to light with a wavelength of 550 nm ranges from 35% to 55%, which is beneficial to improving the light guiding effect of the light guide structure.

[0048] In some embodiments of the first aspect of the present application, the electronic device also includes a middle plate; the middle plate and the screen are stacked, and the frame is arranged around the middle plate and connected to the middle plate; the photosensitive device is located on the side of the middle plate away from the screen; the opening of one end of the through hole adjacent to the inside of the electronic device extends to the side of the middle plate away from the screen; and the light guide is stacked and fixed on the surface of the middle plate facing the photosensitive device.

[0049] In some embodiments of the first aspect of the present application, the surface of the middle plate facing the photosensitive device has a groove, the groove extends to the edge of the middle plate in the direction toward the through hole, and the light guide is positioned in the groove. In this way, on the one hand, positioning the light guide in the groove can facilitate reducing the overall thickness of the light guide, the middle plate and the photosensitive device, so as to further reduce the overall thickness of the electronic device, and facilitate the positioning and installation of the light guide; on the other hand, the groove extends to the edge of the middle plate in the direction toward the through hole, which can facilitate the connection between the light guide and the light guide column.

[0050] Exemplarily, the clearance slot is communicated with the groove, thereby facilitating the connection between the light guide member and the light guide connector.

[0051] In some embodiments of the first aspect of the present application, the electronic device further includes a posture detection device and a processor, the processor is electrically connected to the posture detection device, the photosensitive device and the screen; the posture detection device is used to output angle information, the angle information is used to indicate the angle between the current posture of the electronic device and the horizontal plane; the photosensitive device is used to output light intensity information, the light intensity information is used to indicate the ambient light intensity in the current environment where the electronic device is located; the processor is used to adjust the brightness of the screen according to the light intensity information and the angle information when the angle between the current posture of the electronic device and the horizontal plane is within a preset angle range. In this way, it is beneficial to use the angle information to compensate for the ambient light in the current environment where the electronic device 100 is located detected by the photosensitive device 30, which is beneficial to improve the accuracy of the processor in adjusting the brightness of the screen 10, and facilitate user use.

[0052] In some embodiments of the first aspect of the present application, the processor is used to generate compensation information based on the light intensity information and the angle information when the angle between the current posture of the electronic device and the horizontal plane is within a preset angle range; the processor is also used to generate correction information based on the compensation information and the light intensity information; the processor is also used to adjust the brightness of the screen based on the correction information; wherein the compensation information is used to indicate the ambient light intensity that needs to be compensated, and the correction information is used to indicate the corrected ambient light intensity. In this way, it is conducive to generating accurate compensation information based on the angle information and the light intensity information, and then generating accurate correction information based on the compensation information and the light intensity information, which is conducive to improving the accuracy of the processor in adjusting the screen brightness and facilitating the use of users.

[0053] In some embodiments of the first aspect of the present application, the ambient light intensity to be compensated satisfies the following formula:

[0054] L 补偿 =L0*(45-|A|)*(45-|A|)*C

[0055] Where A is the angle between the current posture of the electronic device and the horizontal plane, L 补偿 is the ambient light intensity that needs to be compensated, L0 is the ambient light intensity corresponding to the light intensity information; and C is a constant.

[0056] Therefore, the ambient light intensity that needs to be compensated and corresponds to the enhancement information generated by the above formula is more accurate, which is beneficial to improving the accuracy of the processor in adjusting the screen brightness and is convenient for users.

[0057] In some embodiments of the first aspect of the present application, the corrected ambient light intensity satisfies the following formula:

[0058] L 修正 =L0+L 补偿

[0059] Among them, L 补偿 is the ambient light intensity that needs to be compensated, L0 is the ambient light intensity corresponding to the light intensity information, and L 修正 is the corrected ambient light intensity.

[0060] As a result, the corrected ambient light intensity corresponding to the correction information generated by the above formula is more accurate, which is beneficial to improving the accuracy of the processor's adjustment of the screen brightness and is more convenient for users.

[0061] In some embodiments of the first aspect of the present application, the preset angle range is [-45°, 45°]. This is conducive to the processor generating accurate compensation information, thereby improving the accuracy of screen brightness adjustment.

[0062] In some embodiments of the first aspect of the present application, when the angle between the current posture of the electronic device and the horizontal plane is not within a preset angle range, the processor is used to adjust the brightness of the screen according to the light intensity information.

[0063] In some embodiments of the first aspect of the present application, the frame includes a first side edge and a third side edge arranged opposite to each other in a first direction, and a through hole is formed on the first side edge; wherein, one end of the electronic device having the first side edge has a sound outlet hole; the electronic device also includes a receiver, and the sound emitted by the receiver is transmitted to the outside of the electronic device through the sound outlet hole; the angle between the current posture of the electronic device and the horizontal plane is the angle between the first direction and the horizontal plane.

[0066] According to the screen brightness control method of the embodiment of the present application, when the angle between the current posture of the electronic device and the horizontal plane is within a preset angle range, first control information is generated based on the angle information and the light intensity information, and the brightness of the screen is adjusted using the first control information, thereby combining the ambient light intensity in the current environment in which the electronic device is located and the angle between the current posture of the electronic device and the horizontal plane. The angle information is used to compensate for the ambient light in the current environment in which the electronic device is located as detected by the photosensitive device, which is beneficial to improving the accuracy of the processor in adjusting the screen brightness and facilitating user use.

[0067] In some embodiments of the second aspect, when the angle between the current posture of the electronic device and the horizontal plane is within a preset angle range, generating the first control information according to the angle information and the light intensity information specifically includes: when the angle between the current posture of the electronic device and the horizontal plane is within the preset angle range, generating compensation information according to the light intensity information and the angle information; wherein the compensation information is used to indicate the ambient light intensity that needs to be compensated; generating correction information according to the compensation information and the light intensity information; wherein the correction information is used to indicate the corrected ambient light intensity; generating the first control information according to the correction information. In this way, it is conducive to generating accurate compensation information according to the angle information and the light intensity information, and then generating accurate correction information according to the compensation information and the light intensity information, which is conducive to improving the accuracy of the processor in adjusting the screen brightness and facilitating user use.

[0068] Specifically, the corrected ambient light intensity is greater than the ambient light intensity in the current environment where the electronic device is located.

[0069] In some embodiments of the second aspect, the ambient light intensity to be compensated satisfies the following formula: 补偿 =L0*(45-|A|)*(45-|A|)*C. Where A is the angle between the current posture of the electronic device and the horizontal plane, L 补偿is the ambient light intensity that needs to be compensated, L0 is the ambient light intensity corresponding to the light intensity information; and C is a constant.

[0071] In some embodiments of the second aspect, the preset angle range is [-45°, 45°]. This is conducive to the processor generating accurate compensation information, thereby improving the accuracy of screen brightness adjustment.

[0074] In a fourth aspect, the present application provides a computer-readable storage medium storing a computer program, wherein the computer program implements any of the above methods when executed by a processor.

[0075] It can be understood that the computer device described in the third aspect provided above and the computer-readable storage medium described in the fourth aspect are both used to execute the corresponding methods provided above. Therefore, the beneficial effects that can be achieved can refer to the beneficial effects in the corresponding methods provided above and will not be repeated here.

[0076] In a fifth aspect, the present application provides a light-guiding structure, comprising: a light-guiding column and a light-guiding member; the light-guiding column is located on one circumferential side of the light-guiding member and is connected to the light-guiding member, and an end of the light-guiding column away from the light-guiding member has a light-entering surface; a surface on one side in the thickness direction of the light-guiding member has a light-emitting surface, and along the thickness direction of the light-guiding member, the light-guiding member is located at one end of the light-guiding column.

[0077] According to the light-guiding structure of the embodiment of the present application, when the light-guiding structure is used in an electronic device, ambient light in the external environment where the electronic device is located can be incident on the light-guiding structure through the light incident surface, and the ambient light can be emitted through the light emitting surface under the guidance of the light-guiding structure. Since the orthographic projection of the photosensitive surface overlaps with the orthographic projection of the light emitting surface in a plane parallel to the screen. Therefore, the ambient light emitted through the light emitting surface can be directed toward the photosensitive surface and sensed by the photosensitive device, thereby realizing the detection of ambient light by the photosensitive device. In this way, there is no need to open a light-through hole on the screen, which is beneficial to improving the structural strength of the screen and the full-screen design of the screen. In addition, there is no need to set the photosensitive device upright on the circuit board, which is beneficial to reducing the thickness of the electronic device and realizing a thin design of the electronic device.

[0078] In some embodiments of the fifth aspect of the present application, in the direction from the light guide to the light guide column, the end of the light guide column away from the light guide is inclined toward the side of the light guide away from the light emitting surface. In this way, the light incident surface can be closer to the display surface of the screen, so that the light intensity of the ambient light incident on the light incident surface is closer to the ambient light intensity between the user and the screen, thereby making the light intensity closer to the light intensity of the user's eyes, thereby improving the accuracy of the light intensity detection of the ambient light by the photosensitive device.

[0079] In some embodiments of the fifth aspect of the present application, the angle between the central axis of the light guide column and the light emitting surface is in a range greater than or equal to 10°.

[0080] Taking into account the difficulty of processing the through hole and the overall structural layout of the electronic device, the angle α between the central axis of the light guide column and the light emitting surface is in the range of greater than or equal to 10° and less than 45°.

[0081] In some embodiments of the fifth aspect of the present application, the roughness of the light incident surface is smaller than the roughness of the light emitting surface. In this way, on the one hand, it is beneficial to set the roughness of the light incident surface to be smaller, thereby facilitating the improvement of the appearance and touch feel of the light incident surface; on the other hand, it is beneficial to set the roughness of the light emitting surface to be larger, thereby facilitating the improvement of the scattering effect of the ambient light when the ambient light is emitted through the light emitting surface, thereby facilitating more ambient light to be emitted to the photosensitive device, thereby improving the reliability of the photosensitive device in detecting ambient light.

[0082] For example, the light guide column and the light guide member can be connected into an integrally formed member by injection molding, which is beneficial to improving the structural strength of the light guide column and the light guide member, simplifying the processing technology of the light guide structure, and reducing the processing cost of the light guide structure.

[0083] In some embodiments of the fifth aspect of the present application, the thickness of the light guide at the light emitting surface is in the range of 0.2 to 0.6 mm. In this way, on the one hand, it can prevent the thickness of the light guide at the light emitting surface from being too large and causing interference with the photosensitive device, and on the other hand, it can also prevent the thickness of the light guide at the light emitting surface from being too small and affecting the light guiding effect of the light guide.

[0084] In some embodiments of the fifth aspect of the present application, a side surface of the light guide in the thickness direction has an avoidance groove, and the avoidance groove surrounds the light emitting surface. In this way, on the one hand, the avoidance groove can be used to avoid the protective member, so that the end of the protective member adjacent to the screen can be accommodated in the avoidance groove, solving the problem of the thickness increase of the protective member due to protrusion from the photosensitive device. On the other hand, it is conducive to ensuring the thickness dimension of the position on the light guide corresponding to the light emitting surface, thereby facilitating the light guiding effect of the light guide and facilitating more ambient light to be directed to the photosensitive surface.

[0085] In some embodiments of the fifth aspect of the present application, the light guide comprises a light guide sheet and a protrusion, the protrusion is arranged on a side surface of the light guide sheet in the thickness direction, an end surface of the protrusion away from the light guide sheet forms a light emitting surface, and a side surface of the protrusion and a side surface of the light guide sheet in the thickness direction jointly define an avoidance groove. The structure is simple.

[0086] In some embodiments of the fifth aspect of the present application, a light guide connector is further included, wherein a light guide column is disposed on one side surface of the light guide connector in the thickness direction, and one side surface of the light guide connector in the thickness direction has a sealing positioning area surrounding the light guide column, and the light guide is disposed on the other side surface of the light guide connector in the thickness direction, and along the thickness direction of the light guide, the light guide is at one end of the light guide connector, and the other side surface of the light guide connector in the thickness direction is connected to the light emitting surface. In this way, a sealing portion can be disposed between the sealing positioning area and the frame, so as to facilitate the use of the sealing portion to seal the gap between the through hole and the light guide column, thereby improving the dustproof and water-repellent effect of the electronic device.

[0087] In some embodiments of the fifth aspect of the present application, the roughness of the other side surface of the light-guiding connector in the thickness direction is greater than the roughness of the light-entering surface and is equal to the roughness of the light-emitting surface. In this way, the roughness of the side surface of the light-guiding connector facing away from the light-guiding column can be set relatively high. Therefore, when the ambient light is transmitted to the light-guiding connector via the light-guiding column, it is helpful to improve the scattering effect of the ambient light on the surface of the light-guiding connector facing the inside of the electronic device, so that more ambient light can be guided to the light-guiding connector, thereby improving the intensity of the ambient light emitted from the light-emitting surface of the light-guiding connector to the photosensitive surface.

[0088] In some embodiments of the fifth aspect of the present application, among the surfaces of the light-guiding structure, except for the light-emitting surface and the other side surface in the thickness direction of the light-guiding connector, the roughness of the remaining surfaces is less than the roughness of the light-emitting surface. In this way, when the external ambient light enters the light-guiding structure through the light-entering surface, the remaining surfaces except the light-entering surface have a certain reflective effect, which can reduce the ambient light emitted from these surfaces, thereby facilitating more ambient light to be directed to the light-emitting surface, and then from the light-emitting surface to the photosensitive surface, thereby improving the reliability of the photosensitive device in detecting ambient light.

[0089] In some embodiments of the fifth aspect of the present application, the light guide structure is an integral injection molded part.

[0090] In some embodiments of the fifth aspect of the present application, the light-guiding structure includes a light-transmitting matrix and diffusion particles, and the diffusion particles are evenly distributed in the light-transmitting matrix. In this way, the ambient light entering the light-guiding structure through the light-incident surface will produce scattering, reflection, and refraction when it is directed toward the diffusion particles, which is conducive to directing more ambient light to the light-emitting surface, thereby increasing the intensity of the ambient light emitted from the light-emitting surface to the photosensitive surface, and increasing the field of view of the photosensitive device and the light-guiding structure as a whole.

[0091] Exemplarily, the field of view angle ranges from 34° to 50°.

[0092] Exemplarily, the material of the light-transmitting substrate includes one or more of polycarbonate, polymethyl methacrylate, a blend of polystyrene and methyl methacrylate, and polystyrene. The material of the diffusion particles includes one or more of polycarbonate, polymethyl methacrylate, a blend of polystyrene and methyl methacrylate, polystyrene, silicon oxide, silicon, melamine, calcium carbonate, Teflon, titanium dioxide, and silicon dioxide.

[0093] For example, in 100 parts by weight of the light guide structure, the weight of the diffusion particles is 40 to 60 parts. In this way, the ambient light entering the light guide structure through the light incident surface will produce scattering, reflection, and refraction when it is directed to the diffusion particles, which is conducive to directing more ambient light to the light emitting surface, thereby increasing the intensity of the ambient light emitted from the light emitting surface to the photosensitive surface.

[0094] In some embodiments of the fifth aspect of the present application, the transmittance of the light guide structure to light with a wavelength of 550 nm is in the range of 35% to 55%, which is conducive to improving the light guiding effect of the light guide structure.

[0137] See also Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of an electronic device 100 according to some embodiments of the present application; Figure 2 Based on Figure 1 An exploded schematic diagram of the electronic device 100 is shown; Figure 3 Based on Figure 1 The cross-sectional structure diagram of the electronic device 100 shown is at the AA line. Wherein, "AA line" refers to the plane where the AA line and the arrows at both ends of the AA line are located. The description of similar figures in the following text should be understood in the same way and will not be repeated in the following text.

The electronic device 100 may include a screen 10, a back shell 20, a photosensitive device 30, a main circuit board 40, a sub-circuit board 80, a battery 60, and a receiver 70.

[0138] Understandably, Figure 1-Figure 3 Only some components of the electronic device 100 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 , Figure 2 and Figure 3 In some other examples, the electronic device 100 may not include at least one of the secondary circuit board 80 and the battery 60.

[0139] The screen 10 is used to display image information, video information, etc. The screen 10 includes a transparent cover plate 11 and a display screen 12. The transparent cover plate 11 is in a flat plate shape. The material of the transparent cover plate 11 includes but is not limited to glass, plastic and ceramic. The transparent cover plate 11 and the display screen 12 are stacked and fixedly connected. The connection method between the transparent cover plate 11 and the display screen 12 includes but is not limited to gluing. The transparent cover plate 11 is mainly used to protect the display screen 12 and prevent dust.

[0140] The display screen 12 can be a flexible display screen or a rigid display screen. For example, the display screen 12 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MIL-E) display screen, a micro organic light-emitting diode (MIL-E) display screen, a micro organic light-emitting diode (MIL-E) display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD), etc. The display surface of the display screen 12 faces the transparent cover plate 11, so that the image, video and other information displayed on the display screen 12 can be observed by the user through the transparent cover plate 11.

[0141] In order to facilitate the description of each embodiment below, an XYZ coordinate system is established for the electronic device 100. Specifically, the thickness direction of the electronic device 100 (that is, the stacking direction of the light-transmitting cover plate 11 and the display screen 12) is defined as the Z-axis direction, and the directions perpendicular to the Z-axis direction are the X-axis direction and the Y-axis direction, and the X-axis direction is perpendicular to the Y-axis direction. Specifically, in this embodiment, the electronic device 100 is in the shape of a rectangular flat plate, wherein the length direction of the electronic device 100 is the Y-axis direction, and the width direction of the electronic device 100 is the X-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 is not specifically limited here.

[0142] Please continue reading Figure 2 and Figure 3, the back shell 20 includes a middle frame 21 and a back cover 22. The middle frame 21 includes a middle plate 212 and a frame 211. The middle plate 212 is in the shape of a rectangular flat plate. The shape of the middle plate 212 is adapted to the shape of the light-transmitting cover plate 11. The middle plate 212 and the screen 10 are stacked in the Z-axis direction. Specifically, the middle plate 212 is stacked on the side of the display screen 12 away from the light-transmitting cover plate 11. The middle plate 212 is used as the structural "skeleton" of the electronic device 100, and the main circuit board 40, the auxiliary circuit board 80, the battery 60, etc. can be fixed on the middle plate 212. It can be understood that in other examples, the middle frame 21 may also not include the middle plate 212, but only include the frame 211. When the middle frame 21 does not include the middle plate 212, the main circuit board 40, the auxiliary circuit board 80, the battery 60, etc. can be fixed on the surface of the display screen 12 away from the light-transmitting cover plate 11, or fixed to the frame 211. In the following description, an example is taken in which the middle frame 21 includes the middle plate 212 .

[0143] The frame 211 is formed into a ring frame structure. Figure 2 The frame 211 includes a first side 2115, a second side 2116, a third side 2117 and a fourth side 2118 connected in sequence. The first side 2115 and the third side 2117 are arranged opposite to each other in a first direction (for example, the Y-axis direction). The second side 2116 and the fourth side 2118 are arranged opposite to each other in the X-axis direction.

[0144] The frame 211 is arranged around the middle plate 212 and the screen 10, and is connected to the middle plate 212 and the screen 10. For details, please refer to Figure 3 A first step 2111 that is recessed in a direction away from the central axis of the frame 211 is formed on a portion of the inner circumference of the frame 211 that is close to the light-transmitting cover plate 11. The edge of the light-transmitting cover plate 11 is supported and fixed on the first step 2111. In this way, the screen 10 can be positioned and installed using the first step 2111, which can improve the installation efficiency. Of course, it is understandable that in other examples, the first step 2111 may not be provided on the frame 211. The outer circumference of the light-transmitting cover plate 11 is connected to the inner circumference of the frame 211. The connection method between the light-transmitting cover plate 11 and the frame 211 includes, but is not limited to, gluing, welding or clamping.

[0145] The middle frame 21 may be an integrally formed structure, that is, the middle plate 212 and the frame 211 are an integral structure. This is conducive to improving the structural strength of the middle frame 21, simplifying the processing technology of the middle frame 21, and reducing the production cost of the middle frame 21. Of course, the present application is not limited to this. In other examples, the middle frame 21 may also be formed by assembling the frame 211 and the middle plate 212. The connection method between the frame 211 and the middle plate 212 includes but is not limited to gluing, clamping, screw connection, welding, etc.

[0146] Please continue reading Figure 2 and Figure 3 , the back cover 22 is located on the side of the middle plate 212 away from the screen 10, and the back cover 22 is stacked and spaced with the middle plate 212. The back cover 22 is in the shape of a flat plate. The material of the back cover 22 includes but is not limited to glass, plastic, metal and ceramic. The frame 211 is arranged around the back cover 22 and is fixed to the back cover 22. Exemplarily, the frame 211 can be fixedly connected to the back cover 22 by means of adhesive, welding or clamping, that is, the frame 211 and the back cover 22 can be assembled together. For example, a second step is formed on the inner circumference of the frame 211 near the back cover 22, which is concave in the direction away from the central axis of the frame 211. The edge of the back cover 22 is supported on the second step. In this way, the second step can be used to position and install the back cover 22, which can improve the installation efficiency. Of course, it can be understood that in other examples, the second step can also be not provided on the frame 211, and the outer circumference of the back cover 22 is connected to the inner circumference of the frame 211. As another example, when the frame 211 and the middle plate 212 are not an integral structure, or the middle plate 212 is not provided in the middle frame 21, the frame 211 can be an integrally formed structure with the back cover 22, that is, the frame 211 and the back cover 22 are an integral structure.

[0147] The main circuit board 40 is used to integrate a control chip. The control chip includes a processor (for example, an application processor (AP), a memory (for example, a double data rate synchronous dynamic random access memory (double data rate, DDR, universal flash storage, UFS)), and a controller. In some embodiments, the main circuit board 40 is electrically connected to the display screen 12, and the main circuit board 40 is used to control the display screen 12 to display images or videos.

[0148] The main circuit board 40 can be a hard circuit board, a flexible circuit board, or a hard-soft circuit board. For example, the main circuit board 40 can be a FR-4 dielectric board, a Rogers dielectric board, or a mixed dielectric board of FR-4 and Rogers, etc. Here, FR-4 is a code for a flame retardant material grade, and Rogers dielectric board is a high-frequency board.

[0149] The main circuit board 40 is located in the frame 211 and fixed relative to the frame 211. Specifically, the main circuit board 40 is fixed to the surface of the middle plate 212 away from the screen 10, that is, the surface facing the back cover 22. Exemplarily, the main circuit board 40 can be fixed to the surface of the middle plate 212 away from the screen 10 by means of threaded connection, clamping, gluing or welding.

[0150] In order to increase the layout area of ​​the main circuit board 40, electronic components are arranged on the surface of the main circuit board 40 facing the screen 10. On this basis, in order to prevent the electronic components on the surface of the main circuit board 40 facing the middle plate 212 from interfering with the middle plate 212, there is an avoidance gap M between the electronic components on the surface of the main circuit board 40 facing the screen 10 and the middle plate 212. Exemplarily, in order to facilitate the formation of the avoidance gap M, a convex portion is provided on the surface of the middle plate 212 facing the back cover 22. The main circuit board 40 is fixed to the convex portion. In other examples, the convex portion may also be provided on the main circuit board 40. For example, the convex portion may be a screw column. Of course, it is understood that in other examples, the formation method of the avoidance gap M is not limited to this, and it may also be that holes or grooves for avoidance are provided at positions corresponding to the electronic components of the middle plate 212. It is sufficient to ensure that the electronic components on the surface of the main circuit board 40 facing the screen 10 and the middle plate 212 are kept at a distance.

[0151] The auxiliary circuit board 80 is used to integrate a universal serial bus (USB) device 80b. The USB device 80b can be a USB type-C interface device, a USB type-A interface device, a USB type Micro-B interface device, or a USB type-B interface device. Figure 2 As shown, a socket 211a is provided on the frame 211 at a position corresponding to the USB device 80b, and accessories such as a charger and a data cable can be electrically connected to the USB device 80b via the socket 211a to achieve transmission of power, signals and data.

[0152] The auxiliary circuit board 80 can be a hard circuit board, a flexible circuit board, or a hard-soft combination circuit board. The auxiliary circuit board 80 can be a FR-4 dielectric board, a Rogers dielectric board, a mixed dielectric board of FR-4 and Rogers, and so on.

[0153] The auxiliary circuit board 80 is located in the frame 211 and is relatively fixed to the frame 211. Specifically, the auxiliary circuit board 80 is fixed to the surface of the middle plate 212 away from the screen 10, that is, the surface facing the back cover 22. Specifically, the auxiliary circuit board 80 can be fixed to the surface of the middle plate 212 away from the screen 10 by means of threaded connection, clamping, gluing or welding. The auxiliary circuit board 80 and the main circuit board 40 are arranged in the Y-axis direction. It can be understood that when electronic components are arranged on the surface of the auxiliary circuit board 80 facing the screen 10, in order to prevent the electronic components on the surface of the auxiliary circuit board 80 facing the screen 10 from interfering with the middle plate 212, there may also be an avoidance gap between the electronic components on the surface of the auxiliary circuit board 80 facing the screen 10 and the middle plate 212 (not shown in the figure).

[0154] The auxiliary circuit board 80 is electrically connected to the main circuit board 40 through the connection structure 80a to achieve data and signal transmission between the auxiliary circuit board 80 and the main circuit board 40. The connection structure 80a can be a flexible printed circuit (FPC). In other embodiments, the connection structure 80a can also be a wire or an enameled wire.

[0155] The battery 60 is fixed on the surface of the middle plate 212 away from the screen 10, that is, the surface facing the back cover 22, and is located between the main circuit board 40 and the auxiliary circuit board 80. In some embodiments, a mounting groove 212a is provided on the surface of the middle plate 212 facing the back cover 22, and the battery 60 is fixed in the mounting groove 212a. It can be understood that in other examples, the mounting groove 212a may not be provided on the middle plate 212, but the side of the main circuit board 40, the side of the auxiliary circuit board 80, the surface of the middle plate 212 facing the back cover 22 and the frame 211 are used to form a mounting groove for placing the battery 60. The battery 60 is used to provide power to the main circuit board 40, the auxiliary circuit board 80, the screen 10 and the photosensitive device 30.

[0156] The battery 60 may include but is not limited to a nickel-cadmium battery, a nickel-metal hydride battery, a lithium battery or other types of batteries. In addition, the number of the battery 60 in the embodiment of the present application may be multiple or one, and the specific number and arrangement of the battery 60 in the embodiment of the present application may be set according to actual needs.

[0157] The receiver 70, also called a "earpiece", is used to convert audio electrical signals into sound signals. The receiver 70 is fixed on the main circuit board 40, and can also be fixed on the auxiliary circuit board 80. Alternatively, in other examples, when the electronic device 100 also includes other circuit boards in addition to the main circuit board 40 and the auxiliary circuit board 80, the receiver 70 can also be fixed on the other circuit boards, as long as the receiver 70 is fixed on the circuit board.

[0158] The first side 2115 has a sound outlet 211b that runs through the first side 2115. The sound emitted by the receiver 70 is transmitted to the outside of the electronic device 100 through the sound outlet 211b. When the electronic device 100 answers a call or voice message, the voice can be answered by placing the sound outlet 211b close to the human ear. In other examples, the sound outlet 211b can also be arranged between the screen 10 and the first side 2115. It is understandable that in other examples, the sound outlet 211b can also be formed at one end of the light-transmitting cover plate 11 of the screen 10 adjacent to the first side 2115. It is sufficient to ensure that the end of the electronic device 100 having the first side 2115 is provided with the sound outlet 211b.

[0159] The photosensitive device 30 can be used to detect the light intensity of the ambient light in the external environment where the electronic device 100 is located. Specifically, the photosensitive device 30 can be an ambient light sensor. The ambient light sensor generally includes a photosensitive element and a logic circuit. The photosensitive element is used to detect ambient light and generate current. The logic circuit includes a current amplifier and a passive low-pass filter to detect and process the output voltage signal caused by the light input. Using the light intensity of the current ambient light in the environment where the electronic device 100 is located measured by the ambient light sensor, the electronic device 100 can realize the function of automatically adjusting the screen brightness. For example, when the ambient light sensor detects that the light intensity of the current ambient light in the environment where the electronic device 100 is located is dark, the brightness of the screen 10 can be reduced to prevent glare; when the ambient light sensor detects that the light intensity of the current ambient light in the environment where the electronic device 100 is located is bright, the brightness of the screen 10 is increased, so that the screen 10 can be displayed more clearly. Of course, it can be understood that in other examples, the photosensitive device 30 can also be a proximity / ambient light sensor that integrates the functions of an ambient light sensor and a proximity light sensor. It is sufficient as long as the photosensitive device 30 has the function of detecting the light intensity of the ambient light in the external environment where the electronic device 100 is located.

[0160] The photosensitive device 30 has a first end 30A1 and a second end 30A2 that are opposite to each other along the thickness direction thereof. The photosensitive device 30 is fixed to the surface of the main circuit board 40 facing the screen 10 by means of the first end 30A1, and is electrically connected to the main circuit board 40. In other examples, the photosensitive device 30 may also be arranged on the surface of the auxiliary circuit board 80 facing the screen 10, and is electrically connected to the auxiliary circuit board 80. Alternatively, in other examples, when the electronic device 100 further includes other circuit boards in addition to the main circuit board 40 and the auxiliary circuit board 80, the photosensitive device 30 may also be fixed to the surface of the other circuit boards facing the screen 10, as long as the photosensitive device 30 is fixed to the surface of the circuit board facing the screen 10. In the following description, the photosensitive device 30 is fixed to the main circuit board 40 as an example for explanation.

[0161] For example, the photosensitive device 30 can be disposed on the main circuit board 40 by using a surface mount device (SMD) process. In this way, the height of the photosensitive device 30 protruding from the main circuit board 40 can be reduced, and the overall thickness of the main circuit board 40 and the photosensitive device 30 can be reduced, thereby facilitating the reduction of the overall thickness of the electronic device 100.

[0162] In order to improve the reliable detection of the light intensity of the ambient light by the photosensitive device 30, the second end 30A2 of the photosensitive device 30 faces the screen 10, and the second end 30A2 of the photosensitive device 30 has a photosensitive surface 301. In order to realize the light sensing of the photosensitive device 30 and prevent the screen 10 and the middle plate 212 from blocking the ambient light, please continue to refer to Figure 2 and Figure 3 A light hole 121 penetrating the display screen 12 is provided in the area directly opposite to the photosensitive surface 301 on the display screen 12, and a light-transmitting hole 212b penetrating the middle plate 212 is provided in the area directly opposite to the light-transmitting hole 121 on the middle plate 212. In this way, ambient light in the external environment where the electronic device 100 is located can be emitted toward the photosensitive surface 301 through the transparent cover plate 11, the light-transmitting hole 121 and the light-transmitting hole 212b in sequence, so as to facilitate the photosensitive device 30 to receive the ambient light. However, the provision of the light-transmitting hole 121 on the screen 10 will, on the one hand, affect the structural strength of the screen 10, and the integrity of the screen 10 is poor; on the other hand, it is not conducive to the full-screen design of the screen 10. In addition, the provision of the light-transmitting hole 212b on the middle plate 212 will also affect the structural strength of the middle plate 212.

[0163] In order to improve the structural strength of the screen 10 and the full-screen design, the structural strength of the middle plate 212 is also improved. Figure 4 and Figure 5 , Figure 4 The schematic diagram of the structure of the electronic device 100 provided in some other embodiments of the present application is as follows: Figure 5 Based on Figure 4 The schematic diagram of the partial cross-sectional structure of the electronic device 100 shown is taken along the BB line, specifically, a cross-sectional view along the positive direction of the X-axis. Figure 1-Figure 3The difference of the embodiment shown is that the light hole 121 on the screen 10 and the light-transmitting hole 212b on the middle plate 212 are omitted. A through hole 211c is provided on the frame 211. The through hole 211c penetrates the frame 211 in the direction from the inner circumference of the frame 211 to the outer circumference of the frame 211. The second end 30A2 of the photosensitive device 30 faces the through hole 211c, so that the photosensitive surface 301 can face the through hole 211c and receive the ambient light emitted into the electronic device 100 through the through hole 211c. The first end 30A1 of the photosensitive device 30 is located on the side of the photosensitive device 30 away from the through hole 211c, that is, the thickness direction of the photosensitive device 30 is consistent with the extension direction of the through hole 211c, resulting in the entire photosensitive device 30 being vertically arranged on the main circuit board 40. This requires that the first end 30A1 of the photosensitive device 30 needs to be provided with an adapter 90 to be electrically connected to the main circuit board 40. In this way, on the one hand, the photosensitive device 30 disposed upright on the main circuit board 40 will occupy the dimension between the middle plate 212 and the main circuit board 40 in the Z-axis direction, resulting in a larger dimension of the avoidance gap M in the Z-axis direction, which in turn results in an increase in the thickness of the entire electronic device 100, which is not conducive to the thin design of the electronic device 100; on the other hand, the photosensitive device 30 disposed upright on the main circuit board 40 results in a smaller contact area between the photosensitive device 30 and the main circuit board 40, and the fixation is not secure. In addition, the provision of the adapter 90 will complicate the assembly process, resulting in an increase in the overall manufacturing cost of the electronic device 100.

[0164] In order to solve the above Figure 1-Figure 5 The technical problems existing in the two solutions shown in the figure are to achieve the problem that the electronic device 100 can improve the structural strength of the screen 10 and the middle plate 212, realize the full-screen design of the screen 10, and take into account the problem of thinning the electronic device 100 and not increasing the cost. Please refer to Figure 6 and Figure 7 , Figure 6 Schematic diagram of the structure of the electronic device 100 according to some other embodiments of the present application. Figure 7 Based on Figure 6 The schematic diagram of the cross-sectional structure of the electronic device 100 shown at the CC line is, specifically, a cross-sectional view toward the positive direction of the X-axis. In this embodiment, the photosensitive device 30 has a first end 30A1 and a second end 30A2 that are opposite to each other along the thickness direction thereof. The photosensitive device 30 is fixed to the surface of the main circuit board 40 facing the screen 10 by means of the first end 30A1, and is electrically connected to the main circuit board 40. The second end 30A2 of the photosensitive device 30 faces the screen 10. The second end 30A2 of the photosensitive device 30 has a photosensitive surface 301 facing the screen 10.

[0165] At the same time, the frame 211 has a through hole 211c. The through hole 211c penetrates the frame 211 in the direction from the inner circumference of the frame 211 to the outer circumference of the frame 211. The opening at one end of the through hole 211c adjacent to the inside of the electronic device 100 extends to the side of the middle plate 212 away from the screen 10, that is, it is located between the middle plate 212 and the back cover 22. Ambient light in the external environment where the electronic device 100 is located can be emitted into the interior of the electronic device 100 through the through hole 211c. It can be understood that when the middle frame 21 does not include the middle plate 212, the opening at one end of the through hole 211c adjacent to the inside of the electronic device 100 is located between the screen 10 and the back cover 22.

[0166] On this basis, in order to guide the ambient light at the through hole 211c to the photosensitive surface 301, please continue to refer to Figure 7 , the electronic device 100 also includes a light guide structure 50 .

[0167] The light guide structure 50 includes a light guide column 501 and a light guide member 502 .

[0168] The light guide column 501 is inserted into the through hole 211c. The light guide column 501 has a light incident surface 5011. The light incident surface 5011 is exposed at the opening of the through hole 211c. The shape of the light guide column 501 includes but is not limited to a cylindrical shape, a regular prism shape, a truncated cone shape, or a column with a special cross section.

[0169] Exemplarily, the equivalent diameter of the cross section of the light guide column 501 ranges from 1 mm to 2 mm. For example, the equivalent diameter of the cross section of the light guide column 501 is 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, or 1.9 mm. It is worth noting that the equivalent diameter of the cross section refers to the diameter of a circle having the same area as the cross section. When the cross section of the light guide column 501 is circular, the equivalent diameter is the diameter of the light guide column 501.

[0170] Specifically, the light guide 502 may be in the form of a sheet. Exemplarily, the light guide 502 may be formed in the form of a rectangular sheet, a trapezoidal sheet, a circular sheet, a triangular sheet, or a special-shaped sheet. Of course, it is understood that in other examples, the light guide 502 may not be in the form of a sheet, but may be in the form of a block, a column, or a special shape, as long as the light guide 502 is disposed between the middle plate 212 and the photosensitive device 30.

[0171] The light guide 502 is located between the middle plate 212 and the photosensitive device 30, and the light guide 502 is laminated and fixed on the surface of the middle plate 212 facing the photosensitive device 30. Exemplarily, the connection between the light guide 502 and the middle plate 212 includes but is not limited to gluing, clamping, screw connection or welding. Figure 7As shown, the light guide 502 is connected to the middle plate 212 via an adhesive structure 212n. On this basis, in order to reduce the space occupied by the adhesive structure 212n, an escape groove 212m is provided on the middle plate 212. The escape groove 212m may also not be provided.

[0172] It is understandable that when the middle frame 21 does not include the middle plate 212, the light guide 502 is laminated and fixed on the surface of the screen 10 facing the photosensitive device 30. It is sufficient to ensure that the light guide 502 is laminated and arranged between the screen 10 and the photosensitive device 30. One circumferential end of the light guide 502 is connected to the light guide column 501. In other words, the light guide column 501 is located on one circumferential side of the light guide 502, and one end of the light guide column 501 adjacent to the inside of the electronic device 100 is connected to the light guide 502.

[0173] The surface of the light guide 502 facing the photosensitive device 30 has a light emitting surface 5021 , that is, one side surface of the light guide 502 in the thickness direction faces the photosensitive device 30 , and the surface has the light emitting surface 5021 .

[0174] See also Figure 8 , Figure 8 Based on Figure 6 and Figure 7 The diagram shows a relative position relationship between the light guide 502 in the electronic device 100 and the vertical projection of the photosensitive surface 301 of the photosensitive device 30 in the plane F parallel to the screen 10. In the plane F parallel to the screen 10, the orthographic projection of the photosensitive surface 301 overlaps with the orthographic projection of the light emitting surface 5021.

[0175] It should be noted that “in plane F parallel to the screen 10, the orthographic projection of the photosensitive surface 301 overlaps with the orthographic projection of the light-emitting surface 5021” means that in plane F parallel to the screen 10, the orthographic projection of the photosensitive surface 301 completely coincides with the orthographic projection of the light-emitting surface 5021; in plane F parallel to the screen 10, the orthographic projection of the photosensitive surface 301 is located within the orthographic projection of the light-emitting surface 5021; in plane F parallel to the screen 10, the orthographic projection of the light-emitting surface 5021 is located within the orthographic projection of the photosensitive surface 301, or, in plane F parallel to the screen 10, a portion of the orthographic projection of the photosensitive surface 301 coincides with a portion of the orthographic projection of the light-emitting surface 5021.

[0176] Exemplarily, the plane F may be a display surface of the display screen 12 , a board surface of the middle plate 212 , or a board surface of the light-transmitting cover plate 11 , etc.

[0177] In this way, on the one hand, the ambient light in the external environment where the electronic device 100 is located can be incident on the light guide structure 50 through the light entrance surface 5011 of the light guide column 501, and the ambient light can be emitted through the light exit surface 5021 under the guidance of the light guide structure 50. Since the orthographic projection of the photosensitive surface 301 overlaps with the orthographic projection of the light exit surface 5021 in the plane parallel to the screen 10. Therefore, the ambient light emitted through the light exit surface 5021 can be directed to the photosensitive surface 301 and sensed by the photosensitive device 30, thereby realizing the detection of the ambient light by the photosensitive device 30. In this way, there is no need to open the light through hole 121 on the screen 10, nor is there a light through hole 212b on the middle plate 212, which is conducive to improving the structural strength of the middle plate 212 and the screen 10, and realizing the full-screen design of the screen 10. On the other hand, although a light guide 502 is additionally provided between the middle plate 212 and the photosensitive device 30, since the light guide 502 is stacked between the middle plate 212 and the photosensitive device 30, and the thickness direction of the photosensitive device 30 is consistent with the thickness direction of the screen 10, the size of the light guide 502 and the photosensitive device 30 as a whole in the thickness direction of the screen 10 is greatly reduced compared with the case where the photosensitive device 30 is vertically provided on the main circuit board 40, which is conducive to reducing the thickness of the electronic device 100 and realizing a thin design of the electronic device 100. In addition, compared with not providing the light guide column 501, providing the light guide column 501 through the through hole 211c is conducive to smoothly guiding more light outside the electronic device 100 to the light guide 502, increasing the field angle of the photosensitive device 30 receiving external light, thereby improving the accuracy of the photosensitive device 30 in detecting external ambient light.

[0178] In short, the electronic device 100 in the embodiment of the present application can take into account both the thinness and full-screen nature of the electronic device 100 , while improving the structural strength of the electronic device 100 .

[0179] In some embodiments of the present application, since the photosensitive device 30 is disposed on the main circuit board 40 and is located within the range surrounded by the outer edge of the main circuit board 40, the distance between the photosensitive device 30 and the through hole 211c in the XY direction is relatively far. In order to take into account the connection between the light guide column 501 and the light guide sheet 5022, and to prevent the light guide 502 from being too close to the center of the middle plate 212 in order to be opposite to the photosensitive surface 301, resulting in the light guide 502 being too large in the arrangement direction of the light guide 502 and the light guide column 501, thereby occupying too much space inside the electronic device 100, please continue to refer to Figure 8 , and combined with Figure 7 In the plane F parallel to the screen 10, a part of the orthographic projection of the photosensitive surface 301 close to the light guide column 501 overlaps with a part of the orthographic projection of the light emitting surface 5021 away from the light guide column 501, thereby forming an overlapping area, such as Figure 8 The filled area is the overlapping area of ​​the two.

[0180] On this basis, specifically, in order to facilitate the ambient light emitted from the light-emitting surface 5021 to cover the photosensitive surface 301 as much as possible so as to be sensed by the photosensitive surface 301, and to improve the reliability of the photosensitive device 30 in detecting the ambient light, in the plane F parallel to the screen 10, the ratio S1 / S2 of the area S1 of the overlapping region to the area S2 of the orthographic projection of the light-emitting surface 5021 is greater than or equal to 0.6 and less than 1. For example, in the plane F parallel to the screen 10, the ratio of the area S1 of the overlapping region to the area S2 of the orthographic projection of the light-emitting surface 5021 is 0.65, 0.7, 075, 0.8, 0.85, 0.9 or 0.95. In other examples, the ratio of the area S1 of the overlapping region to the area S2 of the orthographic projection of the light-emitting surface 5021 may also be a value less than 0.6.

[0181] Specifically, in order to facilitate the ambient light emitted from the light-emitting surface 5021 to cover the photosensitive surface 301 as much as possible so as to be sensed by the photosensitive surface 301, and to improve the reliability of the photosensitive device 30 in detecting the light intensity of the ambient light, in the plane F parallel to the screen 10, the ratio S1 / S3 of the area S1 of the overlapping region to the area S3 of the orthographic projection of the photosensitive surface 301 is greater than or equal to 0.6 and less than 1. For example, in the plane F parallel to the screen 10, the ratio of the area S1 of the overlapping region to the area S3 of the orthographic projection of the photosensitive surface 301 is 0.65, 0.7, 075, 0.8, 0.85, 0.9 or 0.95. In other examples, the ratio of the area S1 of the overlapping region to the area S3 of the photosensitive surface 301 may also be a value less than 0.6.

[0182] Of course, it is understandable that in other embodiments, in order to facilitate the ambient light emitted from the light-emitting surface 5021 to cover the photosensitive surface 301 as much as possible so as to be sensed by the photosensitive surface 301, and to improve the reliability of the photosensitive device 30 in detecting the light intensity of the ambient light, please refer to Fig. 9 , Fig. 9 A schematic diagram of another relative position relationship between the light guide 502 provided in the embodiment of the present application and the vertical projection of the photosensitive surface 301 of the photosensitive device 30 in the plane F parallel to the screen 10. In the plane F parallel to the screen 10, the orthographic projection of the photosensitive surface 301 is located within the orthographic projection of the light emitting surface 5021.

[0183] On this basis, please continue to refer to Fig. 9In order to allow the ambient light emitted from the light-emitting surface 5021 to cover the photosensitive surface 301 as much as possible so as to be sensed by the photosensitive surface 301, while preventing the light guide 502 from occupying too much space inside the electronic device 100 due to the excessive size of the light-emitting surface 5021, in the plane F parallel to the screen 10, the distance d1 between the edge of the orthographic projection of the photosensitive surface 301 and the edge of the orthographic projection of the light-emitting surface 5021 has a value range of greater than 0 and less than or equal to 1.5 mm. Exemplarily, d1 can be 0.2 mm, 0.3 mm, 0.5 mm, 0.8 mm, 1 mm, or 1.2 mm. In other examples, d1 can also be a value greater than 1.5 mm.

[0184] On this basis, please continue to refer to Fig. 9 In order to facilitate the ambient light emitted from the light-emitting surface 5021 to be emitted to the photosensitive surface 301 as much as possible so as to be sensed by the photosensitive surface 301 and to improve the reliability of the photosensitive device 30 in detecting the light intensity of the ambient light, the center of the orthographic projection of the photosensitive surface 301 coincides with the center of the orthographic projection of the light-emitting surface 5021 in the plane F parallel to the screen 10. Of course, it can be understood that in other examples, in the plane parallel to the screen 10, the center of the orthographic projection of the photosensitive surface 301 may not coincide with the center of the orthographic projection of the light-emitting surface 5021.

[0185] On the basis of any of the above embodiments, in some embodiments of the present application, in order to facilitate the ambient light emitted from the light-emitting surface 5021 to cover the photosensitive surface 301 as much as possible so as to be sensed by the photosensitive surface 301, while taking into account the thin design of the electronic device 100, the photosensitive surface 301 and the light-emitting surface 5021 are arranged in parallel, for example, both are parallel to the screen 10. Of course, in other examples, the photosensitive surface 301 and the light-emitting surface 5021 may also be non-parallel, for example, there is an angle of less than 20° between the two.

[0186] On this basis, in some embodiments, in order to facilitate the ambient light emitted from the light-emitting surface 5021 to cover the photosensitive surface 301 as much as possible so as to be sensed by the photosensitive surface 301, while taking into account the thin design of the electronic device 100, and preventing the photosensitive device 30 from colliding with the light guide 502 during the assembly process, please return to refer to Figure 7 The distance d2 between the photosensitive surface 301 and the light emitting surface 5021 has a value ranging from 0.2 to 0.6 mm. For example, the distance d2 between the photosensitive surface 301 and the light emitting surface 5021 is 0.3 mm, 0.4 mm, 0.5 mm or 0.55 mm.

[0187] Based on any of the above embodiments, in some embodiments of the present application, please continue to refer to Figure 7A groove 212c is provided on the surface of the middle plate 212 facing the photosensitive device 30. The groove 212c extends in the direction toward the through hole 211c to the edge of one end of the middle plate 212 adjacent to the through hole 211c. The light guide 502 is positioned in the groove 212c. In this way, on the one hand, positioning the light guide 502 in the groove 212c can reduce the overall thickness of the light guide 502, the middle plate 212 and the photosensitive device 30, so as to further reduce the overall thickness of the electronic device 100, and facilitate the positioning and installation of the light guide 502; on the other hand, the groove 212c extends in the direction toward the through hole 211c to the edge of one end of the middle plate 212 adjacent to the through hole 211c, and an opening can be formed, so that the connection between the light guide 502 and the light guide column 501 is located at the opening without affecting the connection between the two. When the middle plate 212 has the above-mentioned avoidance groove 212m, the avoidance groove 212m is located on the groove bottom wall of the groove 212c. Of course, it can be understood that in other examples, the groove 212c may not be provided.

[0188] Based on any of the above embodiments, please refer to Fig.10 , Fig.10 is the relationship between ambient brightness and screen brightness. Fig.10 The side of the middle dotted line that is far from the safe brightness range is the unsafe range. Fig.10 According to the relationship between the ambient brightness and the screen brightness, the brightness range generally includes a safe brightness range, an acceptable brightness range and a comfortable brightness range. In different brightness ranges, the impact or stimulation felt by the user's eyes is different. Considering that the ambient light intensity between the user's face and the display surface of the electronic device 100 is closer to the ambient light intensity actually felt by the user's eyes, if the light intensity of the ambient light detected by the photosensitive device 30 is closer to the light intensity of the ambient light actually felt by the user's eyes, the brightness of the screen 10 can be adjusted in combination with the light intensity. It is possible to adjust the brightness of the screen 10 to a comfortable brightness range or an acceptable brightness range for the user using the electronic device 100, thereby improving the reliability of the brightness adjustment of the screen 10.

[0189] Based on this, see Fig.11 and Fig.12 , Fig.11 is a schematic diagram of the structure of an electronic device 100 according to some other embodiments of the present application, Fig.12 Based on Fig.11The schematic diagram of the cross-sectional structure of the electronic device 100 shown is at the DD line. In the direction from the light guide 502 to the light guide column 501, the light guide column 501 is inclined toward the side of the light guide 502 away from the light emitting surface 5021, that is, in the direction from the light guide 502 to the light guide column 501, the light guide column 501 is inclined toward the direction close to the screen 10. In this way, it is convenient for the light incident surface 5011 to be closer to the display surface of the screen 10, so that the light intensity of the ambient light incident on the light incident surface 5011 is closer to the ambient light intensity between the user and the screen 10, so that the light intensity is closer to the light intensity of the user's eyes, and the accuracy of the light intensity detection of the ambient light by the photosensitive device 30 is improved.

[0190] On this basis, please continue to refer to Fig.12 In order to facilitate the light incident surface 5011 to be closer to the display surface of the screen 10, so that the light intensity of the ambient light incident on the light incident surface 5011 is closer to the light intensity of the ambient light between the user and the screen 10, the value range of the angle α between the central axis L1 of the light guide column 501 and the screen 10 is greater than or equal to 10°. In other words, the value range of the angle α between the central axis L1 of the light guide column 501 and the screen 10 is greater than or equal to 10° and less than 90°. Exemplarily, when the light emitting surface 5021 is parallel to the screen 10, the angle between the central axis L1 of the light guide column 501 and the light emitting surface 5021 is also α.

[0191] Exemplarily, the angle α between the central axis L1 of the light guide 501 and the screen 10 is 12°, 14°, 15°, 16°, 18°, 20°, 22°, 24°, 25°, 28°, 32°, 35°, 37°, 40°, 45°, 48°, 50°, 55°, 60°, 62°, 65°, 70°, 72°, 75°, 78°, 80°, 82°, 85° or 88°.

[0192] On this basis, considering the difficulty of processing the through hole 211c and the overall structural layout of the electronic device 100, the angle α between the central axis L1 of the light guide column 501 and the screen 10 is greater than or equal to 10° and less than 45°.

[0193] On the basis of any of the above embodiments, in some embodiments of the present application, the roughness of the light incident surface 5011 is less than the roughness of the light emitting surface 5021. In this way, on the one hand, it is beneficial to set the roughness of the light incident surface 5011 to be smaller, thereby facilitating the improvement of the appearance effect and touch feeling of the light incident surface 5011; on the other hand, it is beneficial to set the roughness of the light emitting surface 5021 to be larger, thereby facilitating the improvement of the scattering effect of the ambient light when the ambient light is emitted through the light emitting surface 5021, thereby facilitating more ambient light to be emitted to the photosensitive device 30, thereby improving the reliability of the photosensitive device 30 in detecting the ambient light.

[0194] For example, the light guide column 501 and the light guide member 502 can be connected to form an integral part by injection molding, for example, the entire light guide structure 50 is processed into an integral part by injection molding. In this way, it is beneficial to improve the structural strength of the light guide column 501 and the light guide member 502, simplify the processing technology of the light guide structure 50, and reduce the processing cost of the light guide structure 50.

[0195] Exemplarily, when the light guide structure 50 is processed by injection molding, the inner surface of the mold cavity has a first surface and a second surface. The first surface is used to mold the light incident surface 5011, and the second surface is used to mold the light emitting surface 5021. In order to make the roughness of the light incident surface 5011 smaller than the roughness of the light emitting surface 5021, the first surface can be polished (for example, the roughness of the first surface is Ra0.01), and the second surface is not polished, or the second surface is frosted (for example, the roughness of the second surface is Ra0.55 or Ra0.56) so that the roughness of the first surface is smaller than the roughness of the second surface. In this way, the roughness of the light incident surface 5011 after molding will be smaller than the roughness of the light emitting surface 5021.

[0196] As another example, the first surface may not be polished, nor the second surface may be frosted, but the light emitting surface 5021 of the formed light guide structure 50 may be frosted and the light incident surface 5011 may be polished, as long as the roughness of the light incident surface 5011 is smaller than that of the light emitting surface 5021.

[0197] Of course, it can be understood that the present application is not limited to this. In other examples, the roughness of the light incident surface 5011 may be equal to the roughness of the light emitting surface 5021 , or the roughness of the light incident surface 5011 may be greater than the roughness of the light emitting surface 5021 .

[0198] On the basis of any of the above embodiments, in some embodiments of the present application, the thickness d3 of the light guide 502 at the light exit surface 5021 is in the range of 0.2 to 0.6 mm. In this way, on the one hand, it can prevent the thickness of the light guide 502 at the light exit surface 5021 from being too large and causing interference with the photosensitive device 30, and on the other hand, it can also prevent the thickness of the light guide 502 at the light exit surface 5021 from being too small and affecting the light guiding effect of the light guide 502.

[0199] Exemplarily, the thickness d3 of the light guide 502 at the light emitting surface 5021 is 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, or 0.55 mm.

[0200] On the basis of any of the above embodiments, in order to seal the gap between the light guide column 501 and the through hole 211c to improve the dustproof and waterproof performance of the electronic device 100, in some embodiments of the present application, please continue to refer to Fig.11 A sealing structure 30a is provided between the light guide column 501 and the inner circumference of the through hole 211c. The sealing structure 30a can seal the gap between the light guide column 501 and the inner circumference of the through hole 211c, thereby improving the dustproof and water-repellent effect of the electronic device 100.

[0201] Specifically, the sealing structure 30a can be a sealant. Exemplarily, the sealant can be disposed between the light guide column 501 and the inner circumference of the through hole 211c by a dispensing process. In other examples, the sealing structure 30a can also be a rubber ring or a silicone ring.

[0202] On the basis of any of the above embodiments, in order to seal the gap between the light guide column 501 and the through hole 211c to improve the dust and water resistance of the electronic device 100, in other embodiments of the present application, refer to Fig.13 , Fig.14 and Fig.15 , Fig.13 The structural diagram of the electronic device 100 of some other embodiments of the present application, Fig.14 Based on Fig.13 The cross-sectional structure diagram of the electronic device 100 at line EE is shown. Fig.15 Based on Fig.14The three-dimensional diagram of the light guide structure 50 shown in FIG. The light guide structure 50 also includes a light guide connector 503. Exemplarily, the light guide connector 503 is in the form of a sheet. It can also be in the form of a plate or a block. The light guide connector 503 is located on the side to which the inner circumference of the frame 211 faces, and is stacked and fixed on the inner circumference of the frame 211. The thickness direction of the light guide connector 503 is consistent with the arrangement direction of the light guide 502 and the light guide column 501. The light guide 502 and the light guide column 501 are respectively located at the two ends of the thickness direction of the light guide connector 503. Specifically, the light guide column 501 is fixed on the surface of the light guide connector 503 facing the frame 211. Along the thickness direction of the light guide 502 (that is, the Z-axis direction), the light guide 502 is fixed to one end of the light guide connector 503 adjacent to the middle plate 212, and the surface of the light guide connector 503 facing the inside of the electronic device 100 is connected to the light emitting surface 5021.

[0203] The light guide connector 503 has a sealing positioning area 5031 on its surface facing the frame 211. The sealing positioning area surrounds the light guide column 501. An annular sealing portion 30b is provided between the sealing positioning area 5031 and the inner circumference of the frame 211. The sealing portion 30b is provided around the circumference of the light guide column 501. In this way, the sealing portion 30b can be used to seal the gap between the through hole 211c and the light guide column 501, thereby improving the dust and water resistance of the electronic device 100.

[0204] Exemplarily, the sealing portion 30b can be a sealant. Exemplarily, the sealant can be disposed between the sealing positioning area 5031 and the inner peripheral surface of the frame 211 by a dispensing process. Another exemplary embodiment, the sealant can also be a backing adhesive. In other examples, the sealing portion 30b can also be a rubber ring or a silicone ring.

[0205] For example, please refer to Fig.14 The width d4 of the sealing portion 30b is 0.5 mm to 1.5 mm. For example, the width d4 of the sealing portion 30b is 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, or 1.4 mm.

[0206] Exemplarily, the width d5 ​​of the sealing positioning area 5031 is 0.8 mm to 1.8 mm. Exemplarily, the width d5 ​​of the sealing portion 30b is 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, or 1.7 mm.

[0207] On this basis, in order to prevent the light guide connector 503 from occupying the space inside the electronic device 100, a clearance groove 211d is provided on the inner circumferential surface of the frame 211. The opening of one end of the through hole 211c adjacent to the inside of the back shell 20 is located at the bottom wall of the clearance groove 211d. The light guide connector 503 is located in the clearance groove 211d.

[0208] On this basis, illustratively, when a groove 212 c is provided on the middle plate 212 , the relief groove 211 d is communicated with the groove 212 c , thereby facilitating the connection between the light guide 502 and the light guide connector 503 .

[0209] In some embodiments where the light guide structure 50 has a light guide connector 503, the roughness of the surface of the light guide connector 503 facing away from the light guide column 501 is greater than the roughness of the light incident surface 5011. In this way, the roughness of the surface of the light guide connector 503 facing the inside of the electronic device 100 can be set relatively high. Therefore, when the ambient light is transmitted to the light guide connector 503 via the light guide column 501, it is helpful to improve the scattering effect of the ambient light on the surface of the light guide connector 503 facing the inside of the electronic device 100, so that more ambient light can be guided to the light guide 502, thereby improving the intensity of the ambient light emitted from the light exit surface 5021 of the light guide 502 to the photosensitive surface 301.

[0210] Exemplarily, when the roughness of the light emitting surface 5021 is greater than the roughness of the light incident surface 5011, the roughness of the surface of the light guide connector 503 that is away from the light guide column 501 can be set to be the same as the roughness of the light emitting surface 5021. Exemplarily, when the light guide structure 50 is processed by injection molding, the inner surface of the mold cavity has a first surface, a second surface and a third surface. The first surface is used to mold the light incident surface 5011, the second surface is used to mold the light emitting surface 5021, and the third surface is used to mold the surface of the light guide connector 503 that is away from the light guide column 501. In order to make the roughness of the light incident surface 5011 smaller than the light emitting surface 5021 and smaller than the roughness of the surface of the light guide connector 503 away from the light guide column 501, the first surface may be polished, and the second surface and the surface of the light guide connector 503 away from the light guide column 501 may not be processed, or the second surface and the surface of the light guide connector 503 away from the light guide column 501 may be frosted. In this way, the roughness of the light incident surface 5011 after molding will be smaller than the roughness of the light emitting surface 5021 and smaller than the surface of the light guide connector 503 away from the light guide column 501. As another example, the first surface may not be polished, but the light emitting surface 5021 of the light guide 502 and the surface of the light guide connector 503 away from the light guide column 501 after molding may be frosted, or the light incident surface 5011 of the light guide column 501 may be polished after molding.

[0211] On this basis, among the surfaces of the light-guiding structure 50, except for the light-emitting surface 5021 and the surface of the light-guiding connector 503 facing away from the light-guiding column 501, the roughness of the remaining surfaces is smaller than the roughness of the light-emitting surface 5021, and smaller than the roughness of the surface of the light-guiding connector 503 facing away from the light-guiding column 501. It can be understood that the remaining surfaces include the light-entering surface 5011. In this way, when the external ambient light enters the light-guiding structure 50 through the light-entering surface 5011, the remaining surfaces except the light-entering surface 5011 (for example, the surface of the light-guiding component 502 facing the screen 10, the surface of the light-guiding connector 503 facing the inner circumference of the frame 211, etc.) have a certain reflective effect, which can reduce the ambient light emitted from these surfaces, thereby facilitating more ambient light to be directed to the light-emitting surface 5021, and from the light-emitting surface 5021 to the photosensitive surface 301, thereby improving the reliability of the photosensitive device 30 in detecting ambient light.

[0212] Based on any of the above embodiments, in some embodiments of the present application, please refer to Fig.16 , and combined with Fig.14 ,in, Fig.16 Based on Fig.14 The schematic diagram of the partial cooperation between the main circuit board 40 and the light-guiding structure 50 is shown. In order to prevent the photosensitive device 30 from being damaged due to collision with other structures during transportation or assembly, the electronic device 100 also includes a protective member 40a. The protective member 40a is fixed on the surface of the main circuit board 40 facing the screen 10 and is located on the periphery of the photosensitive device 30. The height of the protective member 40a protruding from the main circuit board 40 is greater than the height of the photosensitive device 30 protruding from the main circuit board 40. In this way, the protective member 40a can be used to protect the photosensitive device 30, and at the same time, the setting of the protective member 40a will not affect the photosensitive device 30 from receiving ambient light.

[0213] On this basis, since the height of the protective member 40a protruding from the main circuit board 40 is greater than the height of the photosensitive device 30 protruding from the main circuit board 40, the overall thickness of the light guide 5022, the protective member 40a and the main circuit board 40 is thickened. In order to reduce the thickness and realize the thinning of the entire electronic device 100, please refer to Fig.17 , Fig.17 Based on Fig.14A three-dimensional view of the light guide structure 50 from another perspective is shown. The surface of the light guide 502 facing the photosensitive device 30 has an avoidance groove 5024. The avoidance groove 5024 surrounds the light emitting surface 5021. The avoidance groove 5024 is used to avoid the protective member 40a. In this way, on the one hand, the avoidance groove 5024 can be used to avoid the protective member 40a, so that the end of the protective member 40a adjacent to the screen 10 can be accommodated in the avoidance groove 5024, solving the problem of the thickness increase of the protective member 40a due to protrusion from the photosensitive device 30. On the other hand, it is helpful to ensure that the thickness dimension at the position corresponding to the light emitting surface 5021 on the light guide sheet 5022 is not too small, so as to improve the light guiding effect of the light guide sheet 5022 and facilitate more ambient light to be emitted to the photosensitive surface 301.

[0214] For details, please continue to refer to Fig.17 , the light guide 502 includes a light guide sheet 5022 and a protrusion 5023. The protrusion 5023 is arranged on the surface of the light guide sheet 5022 facing the photosensitive device 30, and the protrusion 5023 protrudes from the surface of the light guide sheet 5022 facing the photosensitive device 30. An end surface of the protrusion 5023 away from the light guide sheet 5022 (that is, an end surface of the protrusion 5023 facing the photosensitive device 30) forms a light emitting surface 5021. The side surface of the protrusion 5023 and the surface of the light guide sheet 5022 facing the photosensitive device 30 define an avoidance groove 5024. As a result, the structure is simple and easy to process and manufacture.

[0215] Specifically, the shape of the avoidance groove 5024 is adapted to the shape of the protective member 40a. Fig.16 and Fig.17 , the protective member 40a is formed in a U shape, and the avoidance groove 5024 is also in a U shape. Of course, it can be understood that in other examples, the protective member 40a can also be formed in a closed ring shape, and the avoidance groove 5024 is also in a closed ring shape, as long as the shape of the avoidance groove 5024 is compatible with the shape of the protective member 40a.

[0216] Based on any of the above embodiments, in some embodiments of the present application, please continue to refer to Fig.16 , and combined with Fig.14 , the photosensitive device 30 is located in the adjacent through hole 211c of the main circuit board 40 ( Fig.16 The main circuit board 40 is provided with one end of the light guide column 501 (where the light guide column 501 is located). No other electronic components are arranged in the area between the light sensing device 30 and the through hole 211c on the main circuit board 40. In this way, it is advantageous to arrange the light sensing device 30 closer to the through hole 211c, reduce the size of the light guide 502 in the arrangement direction of the light sensing device 30 and the through hole 211c, thereby saving material costs and reducing the space occupied by the light guide 502 inside the electronic device 100.

[0217] Based on any of the above embodiments, in some embodiments of the present application, please refer to Fig.18 , Fig.18 Based on Fig.14 Schematic diagram of components of the light guide structure 50 shown. The light guide structure 50 includes a light-transmitting matrix 50a and diffusion particles 50b. The diffusion particles 50b are evenly distributed in the light-transmitting matrix 50a. In this way, the ambient light entering the light guide structure 50 through the light incident surface 5011 will produce scattering, reflection and refraction when it is directed to the diffusion particles 50b, which is conducive to guiding more ambient light to the light exit surface 5021, thereby increasing the intensity of the ambient light emitted from the light exit surface 5021 to the photosensitive surface 301, and improving the overall field of view of the photosensitive device 30 and the light guide structure 50.

[0218] In addition, different weights of diffusion particles 50b can be added to the light guide structure 50 according to the actual needs of different products to adjust the transmittance and diffusion effect according to different product requirements. For example, when the size of the light incident surface in the light guide structure 50 is relatively small, more diffusion particles 50b can be appropriately added to improve the transmittance and diffusion effect of the entire light guide structure 50. When the size of the light incident surface in the light guide structure 50 is relatively large, less diffusion particles 50b can be appropriately added.

[0219] It is worth noting that when the light source located on the central axis L1 of the light guide column 501 is set to irradiate the light guide structure 50, the light intensity of the ambient light collected by the photosensitive device 30 is V1. The light source is moved along the circumference of the light incident surface 5011 and parallel to the side (for example, the first side) where the through hole 211c is located, or parallel to the direction of the light incident surface 5011, or perpendicular to the central axis L1 of the light guide column 501. When the light source moves to a position where the light intensity of the ambient light collected by the photosensitive device 30 is 0.5V1, the angle between the line connecting the position of the light source and the center of the light incident surface 5011 and the central axis L1 of the light guide column 501 is the field of view angle. Among them, the vertical distance between the light source and the light incident surface is 50cm.

[0220] Exemplarily, the field of view angle ranges from 34° to 50°.

[0221] Exemplarily, the material of the light-transmitting substrate 50a includes one or more of polycarbonate, polymethyl methacrylate, a blend of polystyrene and methyl methacrylate, and polystyrene. The material of the diffusion particles 50b includes one or more of polycarbonate, polymethyl methacrylate, a blend of polystyrene and methyl methacrylate, polystyrene, silicon oxide, silicon, melamine, calcium carbonate, Teflon, titanium dioxide, and silicon dioxide.

[0222] For example, when the light-transmitting matrix 50a is made of polycarbonate, the gray-white polycarbonate has a good diffusion effect on visible light, a larger field of view, relatively continuous reporting at different angles, and no problem of sudden changes in reporting. It can accept the front light source of the screen 10 as much as possible, which is in line with the human eye sight design.

[0223] For example, in 100 parts by weight of the light guide structure 50, the weight of the diffusion particles 50b is 40 to 60 parts. In this way, the ambient light entering the light guide structure 50 through the light incident surface 5011 will produce scattering, reflection, and refraction when it is directed to the diffusion particles 50b, which is conducive to guiding more ambient light to the light emitting surface 5021, thereby increasing the intensity of the ambient light emitted from the light emitting surface 5021 to the photosensitive surface 301.

[0224] In any of the above embodiments where the light guide structure 50 includes a transparent matrix 50a and diffusion particles 50b, the light transmittance of the light guide structure 50 to light with a wavelength of 550nm ranges from 35% to 55%, for example, the light transmittance is 45%, thereby achieving a good light guide effect.

[0225] It is worth mentioning that transmittance refers to the ratio of the light intensity passing through the material to the original light intensity.

[0226] Based on any of the above embodiments, please refer to Fig.13 and Fig.14 , through hole 211c is formed on the first side 2115. For details, please refer to Fig.19 , Fig.19 A scene diagram of a user using the electronic device 100. Fig.19 As shown, when the user uses the electronic device 100, the user is often facing the display surface of the display screen 12, and the end of the frame 211 with the sound outlet 211b is facing upward. By setting the through hole 211c on the first side 2115, the through hole 211c can be set close to the sound outlet 211b. In this way, when the user uses the electronic device 100, the through hole 211c will face upward, and the light source is generally above the user, closer to the light intensity that the user's eyes are exposed to, so that more ambient light located above the user can be directed to the position where the through hole 211c is located, which is conducive to improving the accuracy of the photosensitive device 30 for ambient light detection. In addition, the through hole 211c and the sound outlet 211b are arranged together, with a simple structure, beautiful appearance, and not easy to be blocked. Of course, it can be understood that in other examples, the through hole 211c can also be formed on the second side 2116 and the fourth side 2118 adjacent to the first side 2115.

[0227] Based on any of the above embodiments, please continue to refer to Fig.19When the user uses the electronic device 100, in order to facilitate viewing, the user often tilts the electronic device 100 relative to the user's face in the direction from the user's chest to the user's head toward the direction away from the user's face at a certain angle β. As mentioned above, the impact or stimulation felt by the user's eyes is different in different brightness ranges. Considering that the ambient light intensity between the user's face and the display surface of the electronic device 100 is closer to the ambient light intensity actually felt by the user's eyes, if the ambient light intensity detected by the ambient light sensor is consistent with the ambient light intensity actually felt by the user's eyes, the brightness of the screen 10 can be adjusted in combination with the ambient light intensity. It is possible to adjust the brightness of the screen 10 to a comfortable brightness range or an acceptable brightness range for the user to use the electronic device 100, thereby improving the reliability of the brightness adjustment of the screen 10. However, in combination with Fig.19 When the electronic device 100 is tilted at a certain angle β relative to the user's face in the direction from the user's chest to the user's head in a direction away from the user's face, the through hole 211c on the first side 2115 will be further away from the user, causing the ambient light intensity detected by the photosensitive device to deviate from the ambient light intensity between the user's face and the display surface of the electronic device 100, and therefore, deviate from the ambient light intensity actually felt by the user's eyes, resulting in inaccurate (possibly low) readings from the ambient light sensor.

[0228] Based on this, in order to solve this technical problem, in this embodiment, the current posture of the electronic device 100 is included as a consideration for adjusting the brightness of the screen 10. Fig. 20 and Fig.21 , Fig. 20 Based on Fig.13 and Fig.14 The schematic diagram of electrical connection of the processor, screen 10, gesture detection device and photosensitive device 30 in the electronic device 100 shown in FIG. Fig.21 Based on Fig. 20 A control schematic diagram of the processor in the electronic device 100 shown in the figure adjusts the brightness of the screen 10. The electronic device 100 also includes a posture detection device. The processor, the posture detection device, the photosensitive device 30 and the screen 10 are all electrically connected. Exemplarily, the posture detection device is fixed on the main circuit board 40 so as to be electrically connected to the processor located on the main circuit board 40 through the main circuit board 40. Of course, the posture detection device can also be fixed on the auxiliary circuit board 80.

[0229] Please continue reading Fig.21 The attitude detection device is used to output angle information, and the angle information is used to indicate the angle A between the current attitude of the electronic device 100 and the horizontal plane (combined with Fig.19Specifically, since users use the electronic device 100 most frequently in a sitting position, and users often use the electronic device 100 in portrait orientation more frequently than in landscape orientation, in order to improve the accuracy of adjusting the brightness of the screen 10 and to simplify the control logic of the electronic device 100, the angle A between the current posture of the electronic device 100 and the horizontal plane is determined to be the angle between the arrangement direction (i.e., the Y-axis direction) of the first side 2115 and the third side 2117 and the horizontal plane.

[0230] Exemplarily, the attitude detection device may include an acceleration sensor and / or a gyroscope sensor. Among them, the acceleration sensor can detect the magnitude of the acceleration of the electronic device 100 in various directions (generally three axes). When the attitude of the electronic device 100 is different, the gravity acceleration detected in each coordinate axis of the acceleration sensor itself is different. Using the measurement results in each direction, according to the principle of force decomposition, the angle between each coordinate axis and the gravity direction can be calculated. Therefore, by measuring the angle between each axis of the acceleration sensor coordinate system in the electronic device 100 and the gravity direction, the angular rotation relationship between it and the geographic coordinate system can be obtained, thereby knowing the attitude of the electronic device 100. The gyroscope sensor can determine the angular velocity of the electronic device 100 around three axes. Just as the distance can be obtained by integrating the speed over time, the "angle" rotated by the electronic device can be calculated by integrating the angular velocity over time, which can be used to determine the motion attitude of the electronic device 100. It can be understood that the three-axis coordinates in the attitude detection device can be the same as or different from the XYZ three-axis coordinate system defined in this article for the thickness and length and width of the electronic device 100.

[0231] The photosensitive device 30 is used to output light intensity information, and the light intensity information is used to indicate the ambient light intensity in the current environment where the electronic device 100 is located.

[0232] The processor can receive light intensity information and angle information. The processor judges the received angle information. When the processor determines that the angle A between the current posture of the electronic device 100 and the horizontal plane is within a preset angle range, the processor generates first control information according to the light intensity information and the angle information, and outputs the first control information to the screen 10 for adjusting the brightness of the screen 10.

[0233] In this way, the intensity of ambient light in the current environment where the electronic device 100 is located and the angle A between the current posture of the electronic device 100 and the horizontal plane can be combined, and the angle information can be used to compensate for the ambient light in the current environment where the electronic device 100 is located detected by the photosensitive device 30, which is beneficial to improve the accuracy of the processor's adjustment of the brightness of the screen 10 and facilitate user use.

[0234] In some embodiments, see Fig. 22 , Fig. 22 Based on Fig. 20 Another control schematic diagram of the processor in the electronic device 100 shown in the figure adjusts the brightness of the screen 10. The processor is used to generate the first control information according to the light intensity information and the angle information when the angle A between the current posture of the electronic device 100 and the horizontal plane is within the preset angle range. Specifically, the processor is used to generate compensation information according to the light intensity information and the angle information when the angle A between the current posture of the electronic device 100 and the horizontal plane is within the preset angle range. The compensation information is used to indicate the ambient light intensity that needs to be compensated. The processor is also used to generate correction information according to the compensation information and the light intensity information. The correction information is used to indicate the corrected ambient light intensity. The processor generates the first control information according to the correction information, so that the processor can adjust the brightness of the screen 10 according to the correction information.

[0235] It can be understood that the corrected ambient light intensity is greater than the ambient light intensity in the current environment where the electronic device 100 is located.

[0236] This is helpful for generating accurate compensation information based on the angle information and the light intensity information, and then generating accurate correction information based on the compensation information and the light intensity information, which is helpful for improving the accuracy of the processor's adjustment of the brightness of the screen 10 and facilitating user use.

[0237] For example, please refer to Fig.19 , when the electronic device 100 is tilted at a certain angle β relative to the user's face in the direction from the user's chest to the user's head toward the direction away from the user's face, in order to facilitate observation, the β value is generally not too large. At this time, the angle A between the current posture of the electronic device 100 and the horizontal plane will not be too large. Considering the accuracy of adjusting the brightness of the screen 10, the preset angle range is [-45°, 45°]. This is conducive to the processor generating accurate compensation information, thereby improving the accuracy of adjusting the brightness of the screen 10.

[0238] For details, please refer to Fig.23 , Fig.23 Based on Fig. 20 The processor in the electronic device 100 shown in the figure controls the brightness of the screen 10. The ambient light intensity L that needs to be compensated 补偿 Satisfies the following formula:

[0239] L 补偿 =L0*(45-|A|)*(45-|A|)*C.

[0240] Wherein, L0 is the ambient light intensity corresponding to the light intensity information. A is the angle between the current posture of the electronic device 100 and the horizontal plane. C is a constant. That is, C is a preset compensation coefficient. The C value can be a preset value before the electronic device 100 leaves the factory. It can also be a value set by the user according to actual needs. Exemplarily, the value of C is 0.001, 0.002, 0.003, 0.004, 0.005 or 0.006.

[0241] In this way, the ambient light intensity that needs to be compensated corresponding to the enhancement information generated by the above formula is more accurate, which is beneficial to improving the accuracy of the processor's adjustment of the brightness of the screen 10 and is more convenient for users.

[0242] Specifically, the corrected ambient light intensity L 修 Satisfies the following formula:

[0243] L 修正 =L0+L 补偿 .

[0244] It can be seen from this that the corrected ambient light intensity is the sum of the ambient light intensity that needs to be compensated and the ambient light intensity corresponding to the light intensity information.

[0245] In this way, the correction information generated by the above formula is more accurate, which is beneficial to improving the accuracy of the processor's adjustment of the brightness of the screen 10 and is more convenient for users.

[0246] Based on any of the above embodiments, in some embodiments, when the processor determines that the angle A between the current posture of the electronic device 100 and the horizontal plane is not within a preset angle range, the processor generates second control information based on the light intensity information and outputs the second control information to the screen 10 for adjusting the brightness of the screen 10.

[0247] Exemplarily, when the processor determines that the angle A between the current posture of the electronic device 100 and the horizontal plane is not within a preset angle range, the processor directly generates second control information based on the light intensity information, and outputs the second control information to the screen 10 for adjusting the brightness of the screen 10.

[0248] For example, in order to simplify the screen brightness control method, please continue to refer to Fig.23 When the processor determines that the angle A between the current posture of the electronic device 100 and the horizontal plane is not within the preset angle range, the processor generates the second control information according to the light intensity information, specifically including: when the processor determines that the angle A between the current posture of the electronic device 100 and the horizontal plane is not within the preset angle range, the processor determines the ambient light intensity to be compensated, that is, the above-mentioned L 补偿is 0. The processor then generates second control information according to the light intensity information, and outputs the second control information to the screen 10 for adjusting the brightness of the screen 10.
