Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] Photosensitive devices can detect ambient light intensity by capturing ambient light. The electronic devices in which they are located can adjust the screen brightness based on the detected ambient light intensity, providing convenient conditions for users to observe the information displayed on the screen and realizing automatic adjustment of screen brightness.

[0003] Among related technologies, polless screen technology is becoming increasingly popular. This is because the presence of color filters and black adhesive in polless screens blocks some incident light, resulting in a smaller field of view (FOV) for photosensitive devices.

[0004] A reduced field of view (FOV) can lead to problems such as abnormal ambient light detection at specific angles and abnormal brightness under spotlights during the use of electronic devices, resulting in a decrease in the practicality and reliability of electronic devices and affecting the user experience. Summary of the Invention

[0005] This application aims to provide an ambient light detection component and electronic device that at least solves the problem of misalignment between the optical axes of the camera and the laser focusing sensor.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] This application provides an electronic device, which includes a frame, a display screen, and a light sensing component. The frame and the display screen form a mounting cavity, and the light sensing component is disposed in the mounting cavity. The light sensing component includes a photosensitive sensor and a light guide. The photosensitive sensor faces the display screen, and the light guide is disposed between the display screen and the photosensitive sensor. The light guide includes a light guide post and a light-concentrating part. The light-concentrating part is disposed on the light guide post. External light passes through the display screen and the light-concentrating part in sequence and is received by the photosensitive sensor.

[0008] In the embodiments of this application, the light guide can change the propagation direction of ambient light through its own properties. The ambient light after the change of direction converges towards the inlet on the second side of the light guide, so as to concentrate the ambient light into the inlet.

[0009] This application incorporates a light guide component that converges ambient light in conjunction with a photosensor. This allows the light guide to redirect ambient light, preventing it from reaching the entrance port, thus increasing the maximum incident angle of the ambient light and expanding the field of view (FOV) of the photosensor. This enables the light sensing component to capture ambient light over a wider area without altering its external structure. This compensates for FOV losses caused by reduced electronic device thickness, the widespread adoption of flexible screens, limited display aperture sizes, and obstruction from polarized light technology. Consequently, it reduces issues such as abnormal ambient light detection at specific angles and abnormal brightness under spotlight conditions. Ultimately, this optimizes the structure of the light sensing component, expands its FOV, broadens its application scenarios, improves the practicality and reliability of corresponding electronic devices, and enhances the user experience.

[0038] The following is combined Figures 1 to 21 This application describes an electronic device according to an embodiment of the present application.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to some embodiments of this application, an electronic device 200 includes a frame 220, a display screen 210, and a light sensing component 100. The frame 220 and the display screen 210 form a mounting cavity 2202, and the light sensing component 100 is disposed in the mounting cavity 2202. The light sensing component 100 includes a photosensitive sensor 110 and a light guide 120. The photosensitive sensor 110 faces the display screen 210, and the light guide 120 is disposed between the display screen 210 and the photosensitive sensor 110. The light guide 120 includes a light guide post 124 and a light focusing part 121. The light focusing part 121 is disposed on the light guide post 124. External light passes through the display screen 210 and the light focusing part 121 in sequence and is received by the photosensitive sensor 110.

[0040] in, Figure 1 This is a schematic diagram of the structure of an electronic device 200 according to an embodiment of this application.

[0041] Figure 2 This is a schematic diagram of the structure of an electronic device 200 according to an embodiment of this application.

[0042] Figure 3 This is a schematic diagram of the structure of the optical sensing component 100 according to an embodiment of this application.

[0043] Figure 4 This is a schematic diagram of the structure of the optical sensing component 100 according to an embodiment of this application.

[0044] In this embodiment, an electronic device 200 is defined, which includes a light sensing component 100, a frame 220, and a display screen.

[0045] The frame 220 is the main frame structure of the electronic device 200, used to position and protect other working structures on the electronic device 200. The display screen 210 is mounted on the frame 220, specifically on the front of the frame 220. The display screen 210 and the frame 220 together enclose a mounting cavity 2202, which at least accommodates the light sensing component 100, used to detect the ambient light intensity outside the display screen 210. Specifically, the electronic device 200 also includes a circuit board 230, on which the light sensing component 100 is fixed. The circuit board 230 is connected to the display screen 210, and can control the display brightness of the display screen 210 based on the ambient light intensity detected by the light sensing component 100.

[0046] The light sensing component 100 includes a photosensitive sensor 110. After capturing ambient light, the photosensitive sensor 110 can convert the light signal into an electrical signal. This electrical signal can reflect the ambient light intensity in the current environment. The electronic device 200 can adjust the brightness of the display screen 210 according to the electrical signal. For example, it can increase the brightness when the ambient light intensity is low to prevent the user from not being able to see the information on the display screen 210, or decrease the brightness when the ambient light intensity is high to prevent the glaring display screen 210 from causing visual fatigue to the user.

[0047] The maximum angle of ambient light captured by the photosensitive sensor 110 constitutes the field of view (FOV) of the photosensitive sensor 110. The FOV is not only affected by the size of the photosensitive sensor 110, but also by the structure in the area that the photosensitive sensor 110 faces. For example, the distance between the photosensitive sensor 110 and the front display screen 210, and whether there is any obstruction on the front side of the photosensitive sensor 110 will affect the size of the FOV.

[0048] Based on this, the optical sensing assembly 100 also includes a light guide 120, which includes a focusing section 121 and a light guide post 124. The focusing section 121 is disposed opposite to the photosensitive sensor 110. The side of the focusing section 121 facing away from the photosensitive sensor 110 is designated as the first side. The first side of the focusing section 121 is configured to accommodate structures such as the display screen 210. Ambient light needs to enter the focusing section 121 from the first side. The focusing section 121 can change the propagation direction of the ambient light through its own properties. The ambient light after changing direction converges towards the photosensitive sensor 110 on the second side of the focusing section 121, thereby converging the ambient light to the photosensitive sensor 110. The light guide post 124 is horizontally disposed between the photosensitive sensor 110 and the display screen 210. Ambient light is also refracted as it passes through the light guide post 124, which can also converge the ambient light to a certain extent, thereby expanding the field of view (FOV) of the photosensitive sensor 110.

[0049] The light guide column 124 can also support and position the light-concentrating part 121 to ensure that the light-concentrating part 121 can be accurately stopped at the predetermined working position, reducing the possibility of the light-concentrating part 121 being misaligned or even falling off during vibration and collision, thereby achieving the technical effect of improving the structural stability and reliability of the light-concentrating part 121 and reducing the failure rate of the optical sensing component 100.

[0050] Specifically, such as Figure 2 As shown, in a conventional display screen 210, the FOV (field of view) is determined by factors such as the size of the photosensitive sensor 110, the distance between the photosensitive sensor 110 and the display screen 210, and the transmittance of the display screen 210. However, the display screen 210 using polless technology replaces the PolPolarizer in the conventional display screen 210. Due to the presence of the BM color filter layer 2102 and the black adhesive blocking material, some incident light is blocked, resulting in a reduced FOV angle.

[0051] In the embodiments defined in this application, the field of view (FOV) can be increased by adding a light guide column 124 and a light focusing part 121.

[0052] Therefore, this application, by incorporating a light guide 120 that converges ambient light in conjunction with the photosensitive sensor 110, allows the light guide 120 to change the transmission direction of ambient light, enabling the photosensitive sensor 110 to successfully receive ambient light that would otherwise be unable to reach it. This increases the maximum incident angle of the ambient light and expands the field of view (FOV) of the photosensitive sensor 110, allowing the light sensing component 100 to capture ambient light over a wider range without altering its external structure. This compensates for FOV losses caused by reduced thickness of the electronic device 200, the widespread adoption of flexible screens, limited opening size of the display screen 210, and obstruction caused by polarized light technology. Consequently, it reduces problems such as abnormal ambient light detection at specific angles and abnormal brightness under spotlight conditions. Ultimately, this achieves the technical effects of optimizing the structure of the light sensing component 100, expanding its FOV, broadening its applicable scenarios, improving the practicality and reliability of the corresponding electronic device 200, and optimizing the user experience.

[0053] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 The dashed arrows in the diagram show the propagation path of the ambient light. It can be observed that the ambient light is deflected as it passes through the focusing section 121, converging towards the photosensor 110 compared to its original direction of propagation.

[0054] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the light-concentrating part is a convex lens 122, which can focus external light onto the photosensitive sensor 110.

[0055] In this embodiment, the light-concentrating part 121 is a convex lens 122, which is disposed in front of the photosensitive sensor 110, and a gap is left between the convex lens 122 and the photosensitive sensor 110. The convex lens 122 faces the photosensitive sensor 110, meaning that the principal optical axis of the convex lens 122, passing through the optical center, can pass through the photosensitive sensor 110. The optical center of the convex lens 122 is opposite to the photosensitive sensor 110. After two refractions by the convex lens 122, the ambient light converges towards the focal point on the principal optical axis. Positioning the optical center relative to the photosensitive sensor 110 ensures the focusing effect of the ambient light and reduces the possibility of the ambient light being deflected to the outside of the photosensitive sensor 110.

[0056] in, Figure 2The dashed lines C1 and C2 show the principal optical axes of the two convex lenses 122. The center of the two elliptical convex lenses 122 in the figure corresponds to the optical center of the convex lens 122. In the longitudinal direction of the figure, the optical center is opposite to the photosensitive sensor 110. The intersection point where the ambient light passing through the convex lens 122 converges corresponds to the focal point of the convex lens 122.

[0057] By setting a convex lens 122, the light-gathering effect of the light-gathering part 121 can be enhanced through the light-gathering effect of the convex lens 122, so as to ensure that the ambient light can converge towards the photosensitive sensor 110. Compared with the outward light-gathering structure such as the light-gathering plate, the convex lens 122 has a smaller size in the thickness direction, which can be used in the thinner arrangement space in the electronic device 200. On the other hand, the convex lens 122 itself is transparent and will not form obvious obstruction marks on the display screen 210, which is conducive to maintaining the display effect of the display screen 210.

[0058] like Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments, optionally, there are multiple convex lenses 122; the multiple convex lenses 122 are distributed around the centerline of the photosensitive sensor 110.

[0059] Figure 7 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application.

[0060] Figure 8 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application.

[0061] Figure 9 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application.

[0062] Figure 10 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application.

[0063] Figure 11 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application.

[0064] In this embodiment, a plurality of convex lenses 122 are provided on the light-concentrating part 121. The plurality of convex lenses 122 are distributed on the same plane on the front side of the photosensitive sensor 110, and the plurality of convex lenses 122 are distributed around the center line of the photosensitive sensor 110 to form an annular array of convex lenses 122 on the front side of the photosensitive sensor 110.

[0065] By setting up an array of multiple convex lenses 122, a full-angle light-gathering effect can be formed in front of the photosensitive sensor 110, avoiding the occurrence of light-gathering dead angles in front of the photosensitive sensor 110, and ensuring that the FOV of the light sensing component 100 can be expanded, so as to ensure the accuracy and effectiveness of the ambient light intensity detected by the light sensing component 100.

[0066] Meanwhile, compared to focusing ambient light from multiple directions using a single large convex lens 122, an array of convex lenses 122 composed of multiple small convex lenses 122 can reduce the thickness of the light-gathering part 121, ensuring that the light sensing component 100 can be applied to electronic devices 200 with gradually decreasing thickness, thus providing convenient conditions for miniaturization and lightweight design of electronic devices 200.

[0067] like Figure 3 , Figure 12 , Figure 13 and Figure 20 As shown, in some embodiments, optionally, there is an angle between the principal optical axis of the convex lens 122 and the center line of the light guide post 124; the principal optical axes of multiple convex lenses 122 intersect on the center line of the light guide post 124.

[0068] Figure 12 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application.

[0069] Figure 13 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application, wherein... Figure 13 Arrow a indicates the axial direction of the mounting hole 1242, and arrow b indicates the radial direction of the light guide post 124.

[0070] Figure 20 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application.

[0071] In this embodiment, the convex lens 122 is tilted relative to the reference plane on the front side of the photosensitive sensor 110, specifically tilted towards the center of the photosensitive sensor 110. This reference plane is perpendicular to the centerline of the light guide post 124. After the convex lens 122 is assembled, there is an angle between the principal optical axis of the convex lens 122 and the centerline of the light guide post 124, which corresponds to the tilt angle.

[0072] like Figure 3 and Figure 4 As shown, compared to the tiled convex lens 122 Figure 4 plan, Figure 3 The tilted convex lens 122 can expand the maximum angle of ambient light incidence, as indicated by the dashed arrow in the figure, thereby effectively increasing the field of view (FOV) of the photosensor 110. Meanwhile, compared to... Figure 4In the flat arrangement, the tilted convex lens 122 can deflect the converged ambient light toward the center of the photosensitive sensor 110, thereby reducing the size of the photosensitive sensor 110 without changing other structures, so as to reduce the impact of the light sensing component 100 on the front display screen 210 and thus improve the display effect of the electronic device 200.

[0073] Specifically, when the tilt angle is a first angle value, compared with the flatly arranged convex lens 122, the FOV of the photosensitive sensor 110 can be increased by twice the first angle value.

[0074] like Figure 11 and Figure 12 As shown, in some embodiments, the number of convex lenses 122 is optionally even; the plurality of convex lenses 122 are evenly distributed around the centerline of the light guide post 124.

[0075] In this embodiment, the number of convex lenses 122 is even, specifically, a light-concentrating array can be formed by 12 convex lenses 122.

[0076] Based on this, multiple convex lenses 122 are evenly distributed around the centerline of the light guide post 124. By evenly distributing multiple convex lenses 122, multiple equally divided light-gathering areas can be formed on the light-gathering part 121. The multiple light-gathering areas are symmetrical in pairs. Finally, the optical path combination of multiple evenly distributed convex lenses 122 expands the field of view (FOV) of the light-gathering part 121 itself, thereby expanding the FOV of the photosensitive sensor 110, and thus improving the accuracy and effectiveness of the ambient light intensity detected by the photosensitive sensor 110.

[0077] Meanwhile, the uniform distribution of multiple convex lenses 122 can improve the uniformity of ambient light convergence, avoid the occurrence of ambient light convergence dead zones, and thus improve the practicality and reliability of the light-concentrating part 121.

[0078] like Figure 5 and Figure 6 As shown, in some embodiments, optionally, in the direction of the principal optical axis of the convex lens 122, the distance between the convex lens 122 and the photosensitive sensor 110 is a first spacing, and the focal length of the convex lens 122 is f; the range of the first spacing is: greater than or equal to f and less than or equal to 2f.

[0079] Figure 5 This is a schematic diagram of the structure of the convex lens 122 according to an embodiment of this application, wherein... Figure 5 In the diagram, Axis is the principal optical axis of convex lens 122, Focal point is the focal point of convex lens 122, and d is the thickness of convex lens 122.

[0080] Figure 6In the figure, F is the first distance between the convex lens 122 and the photosensitive sensor 110, and t is the thickness of the convex lens 122.

[0081] Figure 6 This is a schematic diagram of the structure of an electronic device 200 according to an embodiment of this application.

[0082] In this embodiment, ambient light passing through the convex lens 122 is first converged to the focal point of the convex lens 122 by the converging action of the convex lens 122. After passing the focal point, the ambient light diffuses relative to the focal point to generate an image. The greater the distance away from the focal point, the greater the diffusion amplitude of the ambient light.

[0083] Based on this, the focal length of the convex lens 122 is f. Along the principal optical axis of the convex lens 122, the distance between the convex lens 122 and the photosensor 110 is a first spacing, which must be greater than or equal to f and less than or equal to 2f. By limiting the first spacing to be greater than or equal to f, it ensures that ambient light can converge into the photosensor 110, preventing ambient light that has not converged to the focal point from being blocked to the outside of the photosensor 110. By limiting the second spacing to less than or equal to 2f, it prevents excessive diffusion of ambient light after passing through the focal point, preventing ambient light from diffusing to the outside of the photosensor 110. Therefore, by limiting the range of the first spacing, the focusing effect of the convex lens 122 on ambient light can be guaranteed, thereby effectively improving the field of view (FOV) of the photosensor 110.

[0084] Specifically, due to the limited internal space of the electronic device 200, the distance between the convex lens 122 and the photosensitive sensor 110 is restricted to the area between the circuit board 230 and the display screen 210. Therefore, we need to design a corresponding focal length convex lens 122, where the formula for the focal length is as follows:

[0085]

[0086] Where f represents the focal length of convex lens 122, n represents the refractive index of the medium, R1 and R2 represent the radii of curvature of the two surfaces of convex lens 122 respectively, and d represents the thickness of convex lens 122.

[0087] Suppose that in the following design, a lens with a diameter of f = 1.5mm is required, and given n = 1.5, d = 0.5, and R1 = -R2.

[0088] Substituting the formula, we find that when R1 = 1.5mm and R2 = -1.5mm, the focal length f ≈ 1.58mm. This meets the design requirements.

[0089] like Figure 1 , Figure 2 and Figure 12As shown, in some embodiments, optionally, the light guide post 124 includes a mounting hole 1242, and the convex lens 122 is embedded in the mounting hole 1242. The mounting hole 1242 can be a through hole penetrating the light guide post 124, or it can be a blind hole formed on both sides of the light guide post 124.

[0090] Figure 2 The ambient light detection design and optical path are shown. A1 and A2 combine to form an optical FOV angle. Within the same opening requirements and structural dimensions, the angle between A1 and A2 can be increased by the light guide post 124 and the convex lens 122.

[0091] The display 210 features a foam opening design on the back, with the opening size larger than that of the photosensitive sensor 110, to provide a larger space for light transmission.

[0092] A reflective ink coating 140 is sprayed onto the convex lens 122 to prevent internal reflected light from penetrating outward and thus avoid affecting the display effect.

[0093] Without the convex lens 122, the ambient light indicated by B1 and B2 would be blocked by the shielding material, resulting in a reduced field of view (FOV). With the addition of the convex lens 122, the light reaches the convex lens design, and through refraction, the light path is kept within A1 and A2, which constitute the FOV, ensuring that it reaches the photosensor 110.

[0094] like Figure 14 , Figure 15 and Figure 16 As shown, in some embodiments, optionally, the light guide 120 further includes: a positioning member 126 disposed on the inner wall of the mounting hole 1242, the positioning member 126 including a slot 1262, the periphery of the convex lens 122 engaging with the slot 1262; and a support member 128 disposed on the inner wall of the mounting hole 1242, the support member 128 located inside the positioning member 126 in the radial direction of the light guide post 124, the side of the support member 128 facing away from the photosensitive sensor 110 including a support surface 1282, the slot 1262 located between the support surface 1282 and the photosensitive sensor 110 in the axial direction of the mounting hole 1242, and the convex lens 122 abutting against the support surface 1282.

[0095] Figure 14 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application.

[0096] Figure 15 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application.

[0097] Figure 16 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application.

[0098] In this embodiment, a positioning element 126 and a support element 128 are provided in the mounting hole 1242, and specifically the positioning element 126 and the support element 128 are provided on the inner wall surface of the mounting hole 1242.

[0099] The positioning component 126 is provided with a slot 1262. The size of the slot 1262 is adapted to the size of the contour of the convex lens 122. After the assembly is completed, the outer side of the convex lens 122 is inserted into the slot 1262 so as to limit the convex lens 122 in the axial direction of the light guide post 124 through the slot 1262, and prevent the convex lens 122 from moving up and down.

[0100] Correspondingly, a support member 128 is provided on the side of the mounting hole 1242 near the center line of the light guide post 124. The side of the support member 128 facing away from the photosensitive sensor 110 forms a support surface 1282. The support surface 1282 is an inclined curved surface. The shape of the support surface 1282 is adapted to the shape of the curved surface of the convex lens 122 facing the photosensitive sensor 110. After assembly, the convex lens 122 can abut against the support surface 1282, thereby providing effective support for the convex lens 122 through the support member 128 and the support surface 1282, and preventing the convex lens 122 from settling in the mounting hole 1242.

[0101] Therefore, by setting the positioning member 126 and the support member 128 in the mounting hole 1242, the double-end positioning of the convex lens 122 can be achieved by means of the positioning groove and the support surface 1282, so as to ensure that the convex lens 122 can be accurately positioned in the predetermined working position and reduce the possibility of the convex lens 122 being misaligned or even falling off.

[0102] Meanwhile, in the axial direction of the mounting hole 1242, the height of the support surface 1282 is higher than the height of the slot 1262, so that the assembled convex lens 122 can be tilted toward the direction of the photosensitive sensor 110, thereby meeting the tilting installation requirements of the convex lens 122 in the aforementioned embodiment.

[0103] In some embodiments, the optical sensing assembly 100 may optionally include: an adhesive layer for bonding the convex lens 122 and the positioning member 126, and / or for bonding the convex lens 122 and the support member 128.

[0104] In this embodiment, the ambient light also includes an adhesive layer for this component. After the convex lens 122 is installed into the slot 1262 and the support surface 1282, the convex lens 122 can be fixed in the mounting hole 1242 by the adhesive layer. Specifically, the adhesive layer can be bonded between the convex lens 122 and the positioning member 126, and the adhesive layer can also be bonded between the convex lens 122 and the support member 128. The specific location of the adhesive filling can be determined according to the assembly and processing requirements, and this embodiment does not impose any rigid limitations.

[0105] In one embodiment of this application, the assembly process of the convex lens 122 is as follows:

[0106] Figure 17 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application. Figure 17 Corresponding to the first step of assembling the convex lens 122, in this assembly step, one side of the convex lens 122 is first inserted into the slot 1262 in the positioning member 126.

[0107] Figure 18 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application. Figure 18 Corresponding to the second step of assembling the convex lens 122, in this assembly step, the convex lens 122 is pressed down so that the convex lens 122 abuts against the support surface 1282 of the support member 128.

[0108] Figure 19 This is a schematic diagram of the structure of the light-concentrating part 121 according to an embodiment of this application. Figure 19 Corresponding to the third step of the assembly of the convex lens 122, after the convex lens 122 is compacted, an adhesive is filled between the convex lens 122 and the support member 128. After solidification, the adhesive forms an adhesive layer to complete the entire assembly process.

[0109] like Figure 1 As shown, in some embodiments, optionally, a reflective coating 140 is disposed on the peripheral side 1244 of the light guide post 124, and / or the light guide post 124 faces the first end face 1246 of the photosensitive sensor 110; wherein the reflective coating 140 avoids the area on the first end face 1246 opposite to the photosensitive sensor 110.

[0110] In this embodiment, a reflective coating 140 is also sprayed on the light guide column 124, which can prevent ambient light inside the light guide column 124 from being transmitted outward.

[0111] Specifically, the reflective coating 140 can cover the peripheral side 1244 of the light guide post 124. After contacting the reflective coating 140, ambient light is transmitted towards the side where the photosensitive sensor 110 is located, thus preventing ambient light from escaping from all sides of the light guide post 124. The reflective coating 140 can also be sprayed on the first end face 1246 of the light guide post 124 facing the photosensitive sensor 110. In this case, the reflective coating 140 avoids the area on the first end face 1246 opposite to the photosensitive sensor 110, thereby reducing the ambient light scattered to the outside of the photosensitive sensor 110 without affecting the photosensitive sensor 110's ability to capture ambient light.

[0112] Therefore, by setting the reflective coating 140, the loss of ambient light during the convergence process can be reduced, so that the ambient light intensity detected by the photosensor 110 is close to the actual ambient light intensity in the scene. At the same time, the reflective coating 140 can also prevent ambient light from scattering onto the display screen 210, thus preventing ambient light from affecting the display effect of the display screen 210.

Figure 21 This is a schematic diagram of the structure of an electronic device 200 according to an embodiment of this application.

[0114] Specifically, the electronic device 200 can be a terminal or other devices besides a terminal.
