The light guide column is arranged in the through hole in a penetrating mode, the light guide column is provided with a light incident surface exposed out of the through hole, the light guide piece is located at one end, adjacent to the screen, of the light guide column along the thickness direction of the screen, the light guide piece comprises a light emergent surface, and in a plane parallel to the screen, orthographic projection of the light sensitive surface and orthographic projection of the light emergent surface are at least partially overlapped.

According to the electronic device of the embodiment of the application, on one hand, ambient light in the external environment where the electronic device is located can be emitted into the light guide structure through the light incident surface, and the ambient light can be emitted through the light emergent surface under the guidance of the light guide structure. Therefore, the ambient light emitted from the light emitting surface can be emitted to the light sensing surface and perceived by the light sensing device, so that the light sensing device can detect the ambient light. Therefore, a light through hole is not required to be formed in the screen, and the structural strength of the screen and the full-screen design of the screen are improved. On the other hand, although the light guide member is additionally arranged 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 that the size of the light guide member and the photosensitive device in the thickness direction of the screen, which is occupied by the whole body, is greatly reduced compared with the size of the photosensitive device which is vertically arranged on the circuit board; further, as the light guide member is positioned 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 member is arranged is close to the screen and the middle frame, more accommodation spaces are created for the photosensitive devices under the condition that the thickness of the electronic equipment is kept unchanged, and the layout of the electronic equipment is further more compact, so that the thickness of the electronic equipment is reduced, and the thin design of the electronic equipment is realized. In addition, compare with not setting up the leaded light post, wear to locate the through-hole with the leaded light post, be favorable to leading the light guide piece smoothly with the outside more light of electronic equipment, increase the angle of view that the sensitization device received external light to improve the accuracy that the sensitization device detected external environment light.

In short, the electronic equipment in the embodiment of the application can be thinned and fulled at the same time, and the structural strength of the electronic equipment is improved.

Therefore, on one hand, the thickness of the light guide piece at the position of the light emitting surface is prevented from being too large to interfere with the photosensitive device, and on the other hand, the thickness of the light guide piece at the position of the light emitting surface is prevented from being too small to influence the light guide effect of the light guide piece.

In some embodiments of the fifth aspect of the present application, a side surface of the light guide in a thickness direction has a relief groove, and the relief groove surrounds the light exit surface. Therefore, on one hand, the avoidance groove can be utilized to avoid the protective piece, so that one end, adjacent to the screen, of the protective piece can be conveniently accommodated in the avoidance groove, the problem of thickness thickening of the protective piece caused by protruding of the protective piece on the photosensitive device is solved, and on the other hand, the thickness dimension of the position, corresponding to the light-emitting surface, on the light guide piece is guaranteed, the light guide effect of the light guide piece is improved, and more ambient light is emitted to the photosensitive surface.

In some embodiments of the fifth aspect of the present application, the light guide includes a light guide sheet and a protrusion, the protrusion is disposed on a surface of one side of the light guide sheet in a thickness direction, an end surface of the protrusion, which is far away from the light guide sheet, forms a light emitting surface, and a side surface of the protrusion and the surface of one side of the light guide sheet in the thickness direction together define an avoidance groove. The structure is simple.

In some embodiments of the fifth aspect of the present application, the light guide device further includes a light guide connecting member, the light guide pillar is disposed on one side surface of the light guide connecting member in the thickness direction, the one side surface of the light guide connecting member in the thickness direction has a sealing positioning area surrounding the light guide pillar, the light guide member is disposed on the other side surface of the light guide connecting member in the thickness direction, and along the thickness direction of the light guide member, the light guide member is disposed at one end of the light guide connecting member, and the other side surface of the light guide connecting member in the thickness direction is in contact with the light emitting surface. Therefore, the sealing part can be arranged between the sealing positioning area and the frame, so that the gap between the through hole and the light guide column is sealed by the sealing part, and the dustproof water draining effect of the electronic equipment is improved.

In some embodiments of the fifth aspect of the present application, the roughness of the other side surface of the light guiding connection member in the thickness direction is greater than the roughness of the light incident surface and equal to the roughness of the light emergent surface. Therefore, the roughness of one side surface of the light guide connecting piece, which is far away from the light guide column, is set relatively higher, so that when ambient light is transmitted to the light guide connecting piece through the light guide column, the scattering effect of the ambient light on the surface of the light guide connecting piece, which faces the electronic equipment, is improved, more ambient light can be guided to the light guide piece, and the intensity of the ambient light emitted from the light emitting surface of the light guide piece to the light sensing surface is improved.

In some embodiments of the fifth aspect of the present application, the roughness of the surface of the light guiding structure except for the light emitting surface and the other surface of the light guiding connecting member in the thickness direction is smaller than that of the light emitting surface. Therefore, when the external environment light is injected into the light guide structure through the light incidence surface, other surfaces except the light incidence surface in the other surfaces have certain reflection effect, and the emission of the environment light from the surfaces can be weakened, so that more environment light is favorably guided to the light incidence surface, and is emitted to the light sensitive surface from the light incidence surface, and the reliability of the light sensitive device for detecting the environment light is further improved.

In some embodiments of the fifth aspect of the application, the light guiding structure is an integral injection molded part.

In some embodiments of the fifth aspect of the present application, the light guiding structure includes a light transmissive matrix and diffusion particles, the diffusion particles being uniformly distributed within the light transmissive matrix. Therefore, when the ambient light is emitted into the light guide structure through the light incident surface, phenomena such as scattering, reflection and refraction can be generated when the ambient light is emitted to the diffusion particles, so that more ambient light can be favorably guided to the light emergent surface, the intensity of the ambient light emitted to the light sensitive surface from the light emergent surface can be further improved, and the overall field angle of the light sensitive device and the light guide structure can be improved.

Illustratively, the field angle has a value in the range of 34 to 50 °.

In some embodiments of the fifth aspect of the present application, the light guiding structure has a light transmittance in a range of 35% to 55% for light having a wavelength of 550 nm. Thus, the light guide effect of the light guide structure is improved.

Referring to fig. 1, fig. 2, and fig. 3, fig. 1 is a schematic structural diagram of an electronic device 100 according to some embodiments of the present disclosure; FIG. 2 is an exploded schematic view of the electronic device 100 shown in FIG. 1; fig. 3 is a schematic cross-sectional structure at line A-A of the electronic device 100 shown in fig. 1. The "A-A line" refers to the plane where the A-A line and the arrows at the two ends of the A-A line are located, and the description of the similar drawings should be understood in the same manner, and will not be repeated in the following. In this embodiment, the electronic device 100 is a mobile phone. The electronic device 100 may include a screen 10, a back case 20, a photosensitive device 30, a main circuit board 40, a sub circuit board 80, a battery 60, and a receiver 70.

It will be appreciated that fig. 1-3 only schematically illustrate some of the components included in the electronic device 100, the actual shape, actual size, actual location, and actual configuration of which are not limited by fig. 1, 2, and 3. In other examples, the electronic device 100 may not include at least one of the secondary circuit board 80 and the battery 60.

The screen 10 is used to display image information, video information, and the like. The screen 10 includes a light transmissive cover plate 11 and a display screen 12. The light-transmitting cover plate 11 is flat. The material of the light-transmitting cover plate 11 includes, but is not limited to, glass, plastic, and ceramic. The light-transmitting cover plate 11 is laminated with the display screen 12 and fixedly connected. The connection between the light-transmitting cover plate 11 and the display screen 12 includes, but is not limited to, gluing. The light-transmitting cover plate 11 is mainly used for protecting and preventing dust of the display screen 12.

The display 12 may be a flexible display or a rigid display. For example, the display 12 may be an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a mini-led (mini organic light-emitting diode) display, a micro-led (micro organic light-emitting diode) display, a micro-organic led (micro organic light-emitting diode) display, a quantum dot led (quantum dot light emitting diodes, QLED) display, or a liquid crystal display (liquid crystal display, LCD), among others. The display surface of the display screen 12 faces the transparent cover plate 11, so that information such as images, videos and the like displayed on the display screen 12 can be observed by a user through the transparent cover plate 11.

For convenience of description of the embodiments below, an XYZ coordinate system is established for the electronic device 100. Specifically, the thickness direction of the electronic device 100 (i.e., the lamination direction of the light-transmitting cover plate 11 and the display screen 12) is defined as the Z-axis direction, the directions perpendicular to the Z-axis direction are the X-axis direction and the Y-axis direction, respectively, and the X-axis direction and the Y-axis direction are perpendicular. Specifically, in this embodiment, the electronic device 100 has a rectangular flat plate shape, 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 is to be understood that the coordinate system of the electronic device 100 may be flexibly set according to actual needs, which is not specifically limited herein.

With continued reference to fig. 2 and 3, the back shell 20 includes a center frame 21 and a back cover 22. Middle frame 21 includes middle plate 212 and rim 211. The middle plate 212 has a rectangular flat plate shape. The shape of the middle plate 212 is adapted to the shape of the light-transmitting cover plate 11. The middle plate 212 is stacked on the screen 10 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 midplane 212 serves as a structural "backbone" for the electronic device 100 and the primary circuit board 40, secondary circuit board 80, battery 60, etc. may be secured to the midplane 212. It will be appreciated that in other examples, middle frame 21 may not include middle plate 212, but only frame 211. When the middle frame 21 does not include the middle plate 212, the main circuit board 40, the sub circuit board 80, the battery 60, etc. may be fixed on the surface of the display screen 12 remote from the light-transmitting cover plate 11, or fixed to the frame 211. In the following description, the middle frame 21 is described as including the middle plate 212 as an example.

The rim 211 is formed as a ring-shaped frame structure. Specifically, with continued reference to fig. 2, the frame 211 includes a first side 2115, a second side 2116, a third side 2117, and a fourth side 2118, which are connected in sequence. Wherein the first side 2115 and the third side 2117 are oppositely disposed in a first direction (e.g., Y-axis direction). The second side 2116 and the fourth side 2118 are opposite to each other in the X-axis direction.

The frame 211 is disposed around a circumference of the middle plate 212 and the screen 10, and is connected to the middle plate 212 and the screen 10. Specifically, referring to fig. 3, a first step 2111 recessed toward a direction away from a central axis of the bezel 211 is formed on a portion of an inner peripheral surface of the bezel 211 near 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 positionally mounted by the first step 2111, and the mounting efficiency can be improved. Of course, it is understood that in other examples, the first step 2111 may not be provided on the bezel 211. The outer circumferential surface of the light-transmitting cover plate 11 is connected to the inner circumferential surface of the bezel 211. The connection between the transparent cover plate 11 and the frame 211 includes, but is not limited to, gluing, welding or clamping.

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 advantageous in improving the structural strength of the middle frame 21, simplifying the processing process of the middle frame 21, and reducing the production cost of the middle frame 21. Of course, the present application is not limited thereto, and in other examples, the middle frame 21 may be assembled by the frame 211 and the middle plate 212, and the connection between the frame 211 and the middle plate 212 may include, but is not limited to, gluing, clamping, screwing, welding, and the like.

With continued reference to fig. 2 and 3, the back cover 22 is located on a side of the middle plate 212 away from the screen 10, and the back cover 22 is stacked and spaced from the middle plate 212. The back cover 22 has a flat plate shape. The material of the back cover 22 includes, but is not limited to, glass, plastic, metal, and ceramic. The frame 211 is disposed around a circumference of the back cover 22 and is fixed to the back cover 22. Illustratively, the frame 211 may 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 may be assembled together. For example, a second step recessed toward a direction away from the central axis of the bezel 211 is formed on a portion of the inner peripheral surface of the bezel 211 near the back cover 22. The edge of the back cover 22 is supported on the second step. Thus, the back cover 22 can be positioned and mounted by the second step, and the mounting efficiency can be improved. Of course, it is understood that in other examples, the frame 211 may not have a second step, and the outer peripheral surface of the back cover 22 is connected to the inner peripheral surface of the frame 211. Also, for example, when the frame 211 and the middle plate 212 are not in a single structure, or when the middle plate 212 is not disposed in the middle frame 21, the frame 211 and the back cover 22 may be in a single structure, i.e. the frame 211 and the back cover 22 are in a single structure.

The main circuit board 40 is used for integrating the control chip. The control chip includes a processor (which may be, for example, an application processor (application processor, AP)), a memory (e.g., double data rate, DDR, universal memory (universal flash storage, UFS)) and a controller, etc. in some embodiments, the main circuit board 40 is electrically connected to the display 12, and the main circuit board 40 is used to control the display 12 to display images or video.

The main circuit board 40 may be a hard circuit board, a flexible circuit board, or a combination of a hard and soft circuit board. For example, the main circuit board 40 may employ an FR-4 dielectric board, a Rogers dielectric board, a mixed dielectric board of FR-4 and Rogers, and so forth. Here, FR-4 is a code of a flame resistant material grade, and the Rogers dielectric board is a high frequency board.

The main circuit board 40 is located in the frame 211 and is fixed relative to the frame 211.

Illustratively, the main circuit board 40 may be secured to the surface of the midplane 212 remote from the screen 10 by screwing, clamping, gluing, or welding.

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 interference between the electronic components on the surface of the main circuit board 40 facing the middle board 212 and the middle board 212, the electronic components on the surface of the main circuit board 40 facing the screen 10 and the middle board 212 have a back-off gap M therebetween. Illustratively, to facilitate forming the relief gap M, a surface of the midplane 212 facing the back cover 22 is provided with a protrusion. The main circuit board 40 is fixed to the convex portion. In other examples, the protrusions may also be provided on the main circuit board 40. For example, the boss may be a screw post. Of course, it is to be understood that, in other examples, the formation of the escape gap M is not limited to this, and holes, grooves, or the like for escaping may be provided at positions of the midplane 212 corresponding to the electronic components. So long as the electronic components on the surface of the main circuit board 40 facing the screen 10 are kept spaced from the midplane 212.

As shown in fig. 2, a socket 211a is disposed on the frame 211 corresponding to the USB device 80b, and accessories such as a charger and a data line can be electrically connected with the USB device 80b through the socket 211a to realize power, signal and data transmission.

The secondary circuit board 80 may be a hard circuit board, a flexible circuit board, or a combination of a hard and soft circuit board. The secondary circuit board 80 may be an FR-4 dielectric board, a Rogers dielectric board, a hybrid dielectric board of FR-4 and Rogers, or the like.

The secondary circuit board 80 is located in the frame 211 and is fixed relative to the frame 211. Specifically, the sub-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 secondary circuit board 80 may be fastened to the surface of the middle plate 212 remote from the screen 10 by screwing, clamping, gluing, welding, or the like. The sub-circuit board 80 is arranged in the Y-axis direction with the main circuit board 40. It will be appreciated that when the electronic components are disposed on the surface of the sub-circuit board 80 facing the screen 10, in order to prevent interference between the electronic components on the surface of the sub-circuit board 80 facing the screen 10 and the middle plate 212, a clearance gap (not shown) may be provided between the electronic components on the surface of the sub-circuit board 80 facing the screen 10 and the middle plate 212.

The secondary circuit board 80 is electrically connected with the main circuit board 40 through a connection structure 80a to realize data and signal transmission between the secondary circuit board 80 and the main circuit board 40. The connection structure 80a may be a flexible circuit board (flexible printed circuit, FPC), among others. In other embodiments, the connection structure 80a may also be a wire or an enameled wire.

The battery 60 is fixed to the surface of the middle plate 212 facing away from the screen 10, i.e., the surface facing the back cover 22, and is located between the main circuit board 40 and the sub circuit board 80. In some embodiments, a mounting slot 212a is provided on the surface of the middle plate 212 facing the back cover 22, and the battery 60 is secured within the mounting slot 212 a. It will be appreciated that in other examples, the middle plate 212 may not be provided with a mounting groove 212a, but a mounting groove for placing the battery 60 may be defined by the side of the main circuit board 40, the side of the sub circuit board 80, the surface of the middle plate 212 facing the back cover 22, and the frame 211. The battery 60 is used to supply power to the main circuit board 40, the sub circuit board 80, the screen 10, the photosensitive device 30, and the like.

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

A receiver 70, also called a "earpiece", is used to convert the audio electrical signal into a sound signal. The receiver 70 may be fixed to the main circuit board 40 or to the sub-circuit board 80. Alternatively, in other examples, when other circuit boards than the main circuit board 40 and the sub circuit board 80 are also included in the electronic apparatus 100, the receiver 70 may be fixed to the other circuit boards as long as the receiver 70 is secured to the circuit boards.

The first side 2115 has an acoustic exit hole 211b extending through the first side 2115. The sound emitted from the receiver 70 is transmitted to the outside of the electronic device 100 through the sound output hole 211b. When the electronic device 100 receives a telephone call or voice message, the voice can be received by placing the sound outlet 211b close to the human ear. In other examples, the sound outlet 211b may also be disposed between the screen 10 and the first side 2115. It will be appreciated that in other examples, the sound outlet hole 211b may be formed at an end of the light-transmitting cover plate 11 of the screen 10 adjacent to the first side 2115. As long as it is ensured, the end of the electronic device 100 having the first side 2115 is provided with the sound outlet hole 211b.

The light sensing device 30 may be used to detect the light intensity of ambient light in the external environment in which the electronic apparatus 100 is located. Specifically, the photosensitive device 30 may be an ambient light sensor. Ambient light sensors typically include a photosensitive element and logic circuitry. The photosensitive element is used to detect ambient light and generate an electrical 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 optical input. The electronic device 100 may implement a function of automatically adjusting screen brightness using the intensity of the current ambient light in the environment in which the electronic device 100 is located, as measured by the ambient light sensor. For example, when the ambient light sensor detects that the intensity of the current ambient light in the environment in which the electronic device 100 is located is dark, the brightness of the screen 10 may be reduced, preventing glare; when the ambient light sensor detects that the intensity of the current ambient light in the environment in which the electronic device 100 is located is brighter, the screen 10 brightness is increased, which may make the screen 10 display clearer. Of course, it will be appreciated that in other examples, the photosensitive device 30 may also be a proximity/ambient light sensor that integrates the functionality of an ambient light sensor and the functionality of a proximity light sensor. As long as it is ensured that the light sensing device 30 has the function of detecting the light intensity of the ambient light of the external environment in which the electronic apparatus 100 is located.

The photosensitive device 30 has a first end 30A1 and a second end 30A2 opposite in the thickness direction thereof. The photosensitive device 30 is fixed to a 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 disposed on a surface of the sub-circuit board 80 facing the screen 10 and electrically connected to the sub-circuit board 80. Alternatively, in other examples, when other circuit boards than the main circuit board 40 and the sub circuit board 80 are further included in the electronic apparatus 100, the photosensitive device 30 may be fixed to the surface of the other circuit boards facing the screen 10, as long as the photosensitive device 30 is secured to the surface of the circuit boards facing the screen 10. In the following description, an example is described in which the photosensitive device 30 is fixed to the main circuit board 40.

For example, the photosensitive device 30 may be disposed on the main circuit board 40 using a surface mount (Surface Mounted 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 being beneficial to reducing the overall thickness of the electronic apparatus 100.

To enhance reliable detection of the intensity of ambient light by the light sensing device 30, the second end 30A2 of the light sensing device 30 is directed towards the screen 10, and the second end 30A2 of the light sensing device 30 has a light sensing surface 301. In order to realize the sensitization of the sensitization device 30, the screen 10 and the middle plate 212 are prevented from shielding the ambient light, please continue to refer to fig. 2 and 3, the region of the display screen 12 opposite to the photosurface 301 is provided with a light-transmitting hole 121 penetrating the display screen 12, and the region of the middle plate 212 opposite to the light-transmitting hole 121 is provided with a light-transmitting hole 212b penetrating the middle plate 212. In this way, the ambient light in the external environment where the electronic device 100 is located can sequentially pass through the transparent cover plate 11, the light-transmitting hole 121 and the light-transmitting hole 212b to emit to the photosensitive surface 301, so as to facilitate the receiving of the ambient light by the photosensitive device 30. However, the light-passing hole 121 formed on the screen 10 affects the structural strength of the screen 10, so that the integrity of the screen 10 is poor, and the full-screen design of the screen 10 is not facilitated. And the light holes 212b formed in the middle plate 212 may also affect the structural strength of the middle plate 212.

To increase the structural strength of screen 10, as well as the full-screen design, the structural strength of midplane 212 is increased. Referring to fig. 4 and 5, fig. 4 is a schematic structural diagram of an electronic device 100 according to another embodiment of the present application, and fig. 5 is a schematic structural diagram of a portion of a cross section of the electronic device 100 shown in fig. 4 at a line B-B, specifically, a cross section facing the positive direction of the X-axis. This embodiment differs from the embodiment shown in fig. 1-3 in that: the arrangement of the light-passing holes 121 on the screen 10 and the light-transmitting holes 212b on the middle plate 212 is omitted. The frame 211 is provided with a through hole 211c. The through hole 211c penetrates the frame 211 in a direction from an inner circumferential surface of the frame 211 to an outer circumferential surface 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 injected into the inside of the electronic apparatus 100 via the through hole 211c. The first end 30A1 of the photosensitive device 30 is located on the side of the photosensitive device 30 facing away from the through hole 211c, that is, the thickness direction of the photosensitive device 30 is consistent with the extending direction of the through hole 211c, so that the entire photosensitive device 30 is vertically disposed on the main circuit board 40. This makes it necessary to additionally provide the adapter 90 at the first end 30A1 of the photosensitive device 30 to be electrically connected to the main circuit board 40. In this way, on the one hand, the photosensitive device 30 erected on the main circuit board 40 occupies the dimension between the middle plate 212 and the main circuit board 40 in the Z-axis direction, so that the dimension of the avoidance gap M in the Z-axis direction becomes larger, and the thickness of the whole electronic device 100 is further increased, which is not beneficial to the thin design of the electronic device 100; on the other hand, the vertical arrangement of the photosensitive device 30 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 fixing is not firm, and the arrangement of the adapter 90 results in a complicated assembly process, which results in an increase in the overall manufacturing cost of the electronic apparatus 100.

In order to solve the technical problems in the two solutions shown in fig. 1-5, so as to achieve the problem that the electronic device 100 can achieve the thinning and the cost non-increasing of the electronic device 100 on the basis of improving the structural strength of the screen 10 and the middle plate 212 and realizing the full-screen design of the screen 10, please refer to fig. 6 and 7, fig. 6 is a schematic structural diagram of the electronic device 100 according to still other embodiments of the present application, and fig. 7 is a schematic structural diagram of a cross section of the electronic device 100 at the C-C line shown in fig. 6, specifically, a cross section facing the positive direction of the X-axis. In the present embodiment, the photosensitive device 30 has a first end 30A1 and a second end 30A2 opposite in the thickness direction thereof. The photosensitive device 30 is fixed to a 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 is directed toward the screen 10. The second end 30A2 of the photosensitive device 30 has a photosensitive surface 301 facing the screen 10.

Meanwhile, the frame 211 has a through hole 211c. The through hole 211c penetrates the frame 211 in a direction from an inner circumferential surface of the frame 211 to an outer circumferential surface of the frame 211. One end of the through hole 211c adjacent to the inside of the electronic device 100 is opened to extend to a side of the middle plate 212 away from the screen 10, that is, between the middle plate 212 and the back cover 22. Ambient light in the external environment in which the electronic device 100 is located may be injected into the interior of the electronic device 100 via the through hole 211c. It will be appreciated that when the middle frame 21 does not include the middle plate 212, an end opening 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.

On the basis of this, in order to guide the ambient light at the through hole 211c to the photosensitive surface 301, please continue to refer to fig. 7, the electronic device 100 further includes a light guiding structure 50.

The light guide structure 50 includes a light guide pillar 501 and a light guide 502.

The light guide pillar 501 is disposed through the through hole 211c. The light guide pillar 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 guiding column 501 includes, but is not limited to, a cylindrical shape, a regular prism shape, a truncated cone shape, or a column shape with a deformed cross section.

Illustratively, the equivalent diameter of the cross section of the light guiding column 501 ranges from 1mm to 2mm. For example, the equivalent diameter of the cross section of the light guiding column 501 is 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, or 1.9mm. It should be noted that, the equivalent diameter of the cross section refers to the diameter of a circle equal to the area of the cross section, and when the cross section of the light guiding column 501 is circular, the equivalent diameter is the diameter of the light guiding column 501.

Specifically, the light guide 502 may be sheet-shaped. By way of example, the light guide 502 may be formed in a rectangular sheet, a trapezoidal sheet, a circular sheet, a triangular sheet, or a shaped sheet. Of course, it is understood that, in other examples, the light guide 502 may be shaped like a block, a column, a special shape, or the like, instead of being shaped like a sheet, as long as the light guide 502 is disposed between the middle plate 212 and the photosensitive device 30.

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. Exemplary ways of connection between light guide 502 and midplane 212 include, but are not limited to, gluing, clamping, screwing, or welding. For example, as shown in fig. 7, the light guide 502 is connected to the middle plate 212 by an adhesive structure 212 n. On this basis, in order to reduce the space occupied by the adhesive structure 212n, the middle plate 212 is provided with a recess 212m. The escape recess 212m may not be provided.

It will be appreciated that when the middle frame 21 does not include the middle plate 212, the light guide 502 is laminated and fixed to the surface of the screen 10 facing the photosensitive device 30. As long as it is ensured that the light guide 502 is disposed between the screen 10 and the photosensitive device 30 in a stacked manner. One end of the light guide 502 in the circumferential direction is connected to the light guide column 501. That is, the light guide pillar 501 is located at one side of the light guide 502 in the circumferential direction, and one end of the light guide pillar 501 adjacent to the inside of the electronic device 100 is connected to the light guide 502.

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

Referring to fig. 8, fig. 8 is a schematic diagram illustrating a relative positional relationship between the light guide 502 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 electronic device 100 shown in fig. 6 and 7. In a plane F parallel to the screen 10, the front projection of the photosurface 301 overlaps the front projection of the light-emitting surface 5021.

It should be noted that, "in the plane F parallel to the screen 10, the front projection of the light sensing surface 301 overlaps with the front projection of the light emitting surface 5021" means that in the plane F parallel to the screen 10, the front projection of the light sensing surface 301 completely overlaps with the front projection of the light emitting surface 5021; in a plane F parallel to the screen 10, the orthographic projection of the photosurface 301 is located in the orthographic projection of the light-emitting surface 5021; in the plane F parallel to the screen 10, the orthographic projection of the light-emitting surface 5021 is located in the orthographic projection of the light-sensing surface 301, or in the plane F parallel to the screen 10, a portion of the orthographic projection of the light-sensing surface 301 coincides with a portion of the orthographic projection of the light-emitting surface 5021.

Illustratively, the plane F may be a display surface of the display screen 12, a plate surface of the middle plate 212, or a plate surface of the light-transmitting cover plate 11, etc.

In this way, on the one hand, the ambient light in the external environment where the electronic device 100 is located can be injected into the light guiding structure 50 through the light incident surface 5011 of the light guiding column 501, and the ambient light can be injected through the light emergent surface 5021 under the guidance of the light guiding structure 50, and the front projection of the light sensitive surface 301 overlaps with the front projection of the light emergent surface 5021 in the plane parallel to the screen 10. Therefore, the ambient light emitted through the light emitting surface 5021 can be emitted to the photosensitive surface 301 and perceived by the photosensitive device 30, so as to realize the detection of the ambient light by the photosensitive device 30. Thus, the light through holes 121 and the light holes 212b are not required to be formed in the screen 10 and the middle plate 212, so that the structural strength of the middle plate 212 and the screen 10 is improved, and the full-screen design of the screen 10 is realized. On the other hand, although the 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 identical to the thickness direction of the screen 10, the size of the entire light guide 502 and the photosensitive device 30 in the thickness direction of the screen 10 is greatly reduced compared with the size of the photosensitive device 30 vertically arranged on the main circuit board 40, thereby being beneficial to reducing the thickness of the electronic device 100 and realizing the thin design of the electronic device 100. In addition, compared with the situation that the light guide column 501 is not arranged, the light guide column 501 is arranged in the through hole 211c in a penetrating mode, so that more light outside the electronic equipment 100 can be smoothly guided to the light guide 502, the angle of view of the light sensing device 30 for receiving external light is increased, and therefore the accuracy of the light sensing device 30 for detecting the external light is improved.

In short, the electronic device 100 in the embodiment of the present application can achieve both thinning and full-screen of the electronic device 100, and simultaneously improve the structural strength of the electronic device 100.

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 peripheral 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 long, in order to allow for the connection between the light guiding post 501 and the light guiding plate 5022, and at the same time, to prevent the light guiding member 502 from being too close to the center of the middle plate 212 in order to be opposite to the light guiding surface 301, the size of the light guiding member 502 in the arrangement direction of the light guiding member 502 and the light guiding post 501 is too large, so that the space inside the electronic device 100 is excessively occupied, and in conjunction with fig. 7, in the plane F parallel to the screen 10, a portion of the orthographic projection of the light guiding post 501 close to the orthographic projection of the light emitting surface 5021 overlaps a portion of the orthographic projection of the light guiding post 501, so as to form an overlapping region, such as the filling region in fig. 8 is an overlapping region of both.

On this basis, specifically, in order to facilitate that the ambient light emitted from the light-emitting surface 5021 can cover the light-sensing surface 301 as much as possible, so as to be perceived by the light-sensing surface 301, the reliability of the detection of the ambient light by the light-sensing device 30 is improved, and in the plane F parallel to the screen 10, the value range of 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 a plane F parallel to the screen 10, the ratio of the area S1 of the overlap 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 can also be a value of less than 0.6.

Specifically, in order to facilitate that the ambient light emitted from the light-emitting surface 5021 can cover the light-sensing surface 301 as much as possible, so as to be perceived by the light-sensing surface 301, and improve the reliability of detecting the light intensity of the ambient light by the light-sensing device 30, in the plane F parallel to the screen 10, the value range of the ratio S1/S3 of the area S1 of the overlapping region to the area S3 of the orthographic projection of the light-sensing surface 301 is greater than or equal to 0.6 and less than 1. For example, in a plane F parallel to the screen 10, the ratio of the area S1 of the overlapping region to the area of 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 overlap region to the area S3 of the photosensitive surface 301 may also be a value smaller than 0.6.

It should be understood that, in other embodiments, in order to facilitate that the ambient light emitted from the light-emitting surface 5021 can cover the light-sensing surface 301 as much as possible, so as to be sensed by the light-sensing surface 301, to improve the reliability of detecting the light intensity of the ambient light by the light-sensing device 30, referring to fig. 9, fig. 9 is a schematic diagram of another relative positional relationship between the light-guiding member 502 and the vertical projection of the light-sensing surface 301 of the light-sensing device 30 in the plane F parallel to the screen 10 according to the embodiment of the present application. In a plane F parallel to the screen 10, the orthographic projection of the photosurface 301 is located within the orthographic projection of the light-emitting surface 5021.

On this basis, in particular, please continue to refer to fig. 9, in order to cover the photosurface 301 as much as possible with the ambient light emitted from the light-emitting surface 5021, so as to be perceived by the photosurface 301, and prevent the light guide 502 from occupying too much space inside the electronic device 100 due to the oversized size of the light-emitting surface 5021, in the plane F parallel to the screen 10, the value range of the distance d1 between the edge of the orthographic projection of the photosurface 301 and the edge of the orthographic projection of the light-emitting surface 5021 is greater than 0 and less than or equal to 1.5mm. Illustratively, d1 may be 0.2mm, 0.3mm, 0.5mm, 0.8mm, 1mm, or 1.2mm. In other examples, d1 may also be a value greater than 1.5mm.

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

On the basis of any of the above embodiments, in some embodiments of the present application, in order to facilitate that the ambient light emitted from the light-emitting surface 5021 can cover the light-sensing surface 301 as much as possible to be sensed by the light-sensing surface 301, and at the same time, the thin design of the electronic device 100 can be considered, the light-sensing surface 301 and the light-emitting surface 5021 are parallel, for example, both are parallel to the screen 10. Of course, in other examples, the light-sensing surface 301 and the light-emitting surface 5021 may not be parallel, for example, have an included angle within 20 °.

On the basis, in some embodiments, in order to facilitate that the ambient light emitted from the light-emitting surface 5021 can cover the light-sensing surface 301 as much as possible to be sensed by the light-sensing surface 301, and also to allow for the thin design of the electronic device 100, the light-sensing device 30 and the light-guiding member 502 are prevented from collision during the assembly process, and referring back to fig. 7, the distance d2 between the light-sensing surface 301 and the light-emitting surface 5021 is in the range of 0.2-0.6 mm. Illustratively, the distance d2 between the light-sensing surface 301 and the light-emitting surface 5021 is 0.3mm, 0.4mm, 0.5mm, or 0.55mm.

Based on any of the above embodiments, in some embodiments of the present application, please continue to refer to fig. 7, a groove 212c is provided on a surface of the middle plate 212 facing the photosensitive device 30. The groove 212c extends to an end edge of the middle plate 212 adjacent to the through hole 211c in a direction toward the through hole 211 c. The light guide 502 is positioned within the recess 212c. In this way, on the one hand, positioning the light guide 502 in the groove 212c can facilitate reducing 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 simultaneously facilitate positioning and mounting of the light guide 502; on the other hand, the groove 212c extends to an end edge of the middle plate 212 adjacent to the through hole 211c in a direction toward the through hole 211c, and may form an opening, so that a connection between the light guide 502 and the light guide pillar 501 is located at the opening without affecting the connection therebetween. When the middle plate 212 has the above-mentioned escape groove 212m, the escape groove 212m is located on the bottom wall of the groove 212c. Of course, it will be appreciated that in other examples, the recess 212c may not be provided.

On the basis of any of the above embodiments, referring to fig. 10, fig. 10 is a graph showing a relationship between ambient brightness and screen brightness, and a side of a broken line far from a safe brightness range in fig. 10 is an unsafe range. Referring to fig. 10, it can be seen that the luminance range generally includes a safe luminance range, an acceptable luminance range, and a comfortable luminance range according to the relationship between the ambient luminance and the screen luminance. The perceived impact or stimulus of the user's eyes is different in different brightness ranges. Considering that the intensity of the ambient light between the face of the user and the display surface of the electronic device 100 is closer to the intensity of the ambient light actually sensed by the eyes of the user, if the intensity of the ambient light detected by the light sensing device 30 is closer to the intensity of the ambient light actually sensed by the eyes of the user, the brightness of the screen 10 can be adjusted by combining the intensities of the ambient light to adjust the brightness of the screen 10 to a comfortable brightness range or an acceptable brightness range of the user using the electronic device 100, so that the reliability of adjusting the brightness of the screen 10 is improved.

Referring to fig. 11 and 12, fig. 11 is a schematic structural diagram of an electronic device 100 according to some other embodiments of the present application, and fig. 12 is a schematic sectional structural diagram of the electronic device 100 at line D-D shown in fig. 11. The light guide pillar 501 is inclined toward a side facing away from the light exit surface 5021 near the light guide member 502 in a direction from the light guide member 502 to the light guide pillar 501, that is, the light guide pillar 501 is inclined toward a side facing toward the screen 10 in a direction from the light guide member 502 to the light guide pillar 501. Therefore, the light incident surface 5011 can be more close 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 more close to the ambient light intensity between the user and the screen 10, the light intensity is more close to the light intensity of eyes of the user, and the accuracy of detecting the light intensity of the ambient light by the photosensitive device 30 is improved.

On this basis, in particular, 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, and the value range of the included angle α between the central axis L1 of the light guiding post 501 and the screen 10 is greater than or equal to 10 °. That is, the included angle α between the central axis L1 of the light guiding column 501 and the screen 10 has a value ranging from 10 ° or more to 90 °. For example, when the light-emitting surface 5021 is parallel to the screen 10, the included angle between the central axis L1 of the light guiding pillar 501 and the light-emitting surface 5021 is also α.

Illustratively, the included angle α between the central axis L1 of the light guiding column 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 °.

On this basis, in consideration of the processing difficulty of the through hole 211c and the overall structural layout of the electronic device 100, the value range of the included angle α between the central axis L1 of the light guide column 501 and the screen 10 is 10 ° or more and 45 ° or less.

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 smaller than the roughness of the light emergent surface 5021. In this way, on one hand, the roughness of the light incident surface 5011 is set smaller, so that the appearance effect and touch feel of the light incident surface 5011 are improved; on the other hand, the roughness of the light-emitting surface 5021 is better to be larger, so that when the ambient light is emitted through the light-emitting surface 5021, the scattering effect on the ambient light is better to be improved, more ambient light is better to be directed to the photosensitive device 30, and the reliability of the photosensitive device 30 on the ambient light detection is improved.

Illustratively, the light guide post 501 and the light guide 502 may be connected as an integral piece by an injection molding process, e.g., the entire light guide structure 50 is machined as an integral piece by an injection molding process. In this way, the structural strength of the light guide post 501 and the light guide member 502 is improved, the processing technology of the light guide structure 50 is simplified, and the processing cost of the light guide structure 50 is reduced.

Illustratively, when the light guide structure 50 is manufactured using an injection molding process, the inner surface of the mold cavity has a first surface and a second surface. The first surface is used for forming the light incident surface 5011, the second surface is used for forming the light emergent surface 5021, in order to make the roughness of the light incident surface 5011 smaller than the roughness of the light emergent surface 5021, the first surface may be polished (for example, the roughness of the first surface is ra 0.01), the second surface may not be polished, or the second surface may be frosted (for example, the roughness of the second surface is ra0.55 or ra 0.56) so that the roughness of the first surface is smaller than the roughness of the second surface, and thus, the roughness of the light incident surface 5011 after forming is smaller than the roughness of the light emergent surface 5021.

Also, for example, the light emitting surface 5021 of the molded light guiding structure 50 may be frosted and the light entering surface 5011 may be polished without polishing the first surface and the second surface. As long as the roughness of the light incident surface 5011 can be made smaller than the roughness of the light emergent surface 5021.

Of course, it is understood that the present application is not limited thereto, and in other examples, the roughness of the light incident surface 5011 and the roughness of the light emergent surface 5021 may be equal, or the roughness of the light incident surface 5011 may be greater than the roughness of the light emergent surface 5021.

Based on any of the above embodiments, in some embodiments of the present application, the thickness d3 of the light guide 502 at the position of the light exit surface 5021 is in the range of 0.2-0.6 mm. Thus, on the one hand, the thickness of the light guide 502 at the position of the light-emitting surface 5021 is prevented from being too large to interfere with the photosensitive device 30, and on the other hand, the thickness of the light guide 502 at the position of the light-emitting surface 5021 is prevented from being too small to influence the light guiding effect of the light guide 502.

Illustratively, the thickness d3 of the light guide 502 at the position of the light-emitting surface 5021 has a value of 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, or 0.55mm.

In order to seal the gap between the light guide pillar 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, referring to fig. 11, a sealing structure 30a is disposed between the light guide pillar 501 and the inner peripheral surface of the through hole 211 c. The sealing structure 30a may seal a gap between the light guide pillar 501 and the inner circumferential surface of the through hole 211c, thereby improving the dust-proof drainage effect of the electronic device 100.

Specifically, the sealing structure 30a may be a sealant. Illustratively, a sealant may be disposed between the light guide post 501 and the inner circumferential surface of the through hole 211c by a dispensing process. In other examples, the sealing structure 30a may also be a rubber ring or a silicone ring.

In order to seal the gap between the light guide post 501 and the through hole 211c to improve the dustproof performance of the electronic device 100, in other embodiments of the present application, please refer to fig. 13, 14 and 15, fig. 13 is a schematic structural diagram of the electronic device 100 according to other embodiments of the present application, fig. 14 is a schematic sectional structural diagram of the electronic device 100 at line E-E shown in fig. 13, and fig. 15 is a perspective view of the light guide structure 50 shown in fig. 14. The light guiding structure 50 further comprises a light guiding connection 503. Illustratively, the light guide connector 503 is sheet-like. Or may be plate-shaped or block-shaped. The light guide connector 503 is positioned on the side facing the inner peripheral surface of the frame 211, and is laminated and fixed on the inner peripheral surface of the frame 211. The thickness direction of the light guide connection member 503 is the alignment direction of the light guide 502 and the light guide pillar 501. The light guide 502 and the light guide pillar 501 are located at both ends of the light guide connection 503 in the thickness direction. Specifically, the light guiding columns 501 are fixed on the surface of the light guiding connection member 503 facing the frame 211. Along the thickness direction (i.e., the Z-axis direction) of the light guide 502, the light guide 502 is fixed to an end of the light guide connector 503 adjacent to the middle plate 212, and a surface of the light guide connector 503 facing the inside of the electronic device 100 is in contact with the light emitting surface 5021.

The surface of the light guide connection member 503 facing the frame 211 has a seal positioning area 5031 thereon. The seal positioning area surrounds the light guiding column 501. An annular seal portion 30b is provided between the seal positioning region 5031 and the inner peripheral surface of the frame 211. The sealing portion 30b is provided around the circumference of the light guiding column 501. In this way, the gap between the through hole 211c and the light guide column 501 can be sealed by the sealing portion 30b, thereby improving the dust-proof water discharge effect of the electronic device 100.

The sealing portion 30b may be, for example, a sealant. Illustratively, the sealant may be disposed between the seal positioning area 5031 and the inner peripheral surface of the bezel 211 by a dispensing process. Also, as an example, a back adhesive may be used as the sealant. In other examples, the sealing portion 30b may also be a rubber ring or a silicone ring.

For example, with continued reference to fig. 14, the width d4 of the sealing portion 30b is 0.5mm to 1.5mm. Illustratively, the width d4 of the seal 30b is 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, or 1.4mm.

Illustratively, the seal positioning area 5031 has a width d5 of 0.8mm to 1.8mm. Illustratively, the width d5 of the seal 30b is 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, or 1.7mm.

In order to prevent the light guide connector 503 from occupying the space inside the electronic device 100, the inner peripheral surface of the frame 211 is provided with a relief groove 211d. One end of the through hole 211c adjacent to the inside of the back case 20 is open at the groove bottom wall of the relief groove 211d. The light guide connection 503 is located in the relief groove 211d.

On this basis, when the groove 212c is provided on the middle plate 212, the relief groove 211d communicates with the groove 212c, so that the connection between the light guide 502 and the light guide connection 503 can be facilitated.

In some embodiments in which the light guiding structure 50 has a light guiding connection 503, a surface of the light guiding connection 503 facing away from the light guiding pillar 501 has a roughness greater than that of the light incident surface 5011. In this way, the roughness of the surface of the light guide connection member 503 facing the interior of the electronic device 100 can be set relatively high, so that when the ambient light is transmitted to the light guide connection member 503 via the light guide pillar 501, the scattering effect of the ambient light at the surface of the light guide connection member 503 facing the interior of the electronic device 100 is advantageously improved, so that more ambient light can be guided to the light guide member 502, and the intensity of the ambient light emitted from the light emitting surface 5021 of the light guide member 502 to the light sensing surface 301 is advantageously improved.

For example, when the roughness of the light-emitting surface 5021 is greater than the roughness of the light-entering surface 5011, the roughness of the surface of the light guide connector 503 facing away from the light guide pillar 501 may be set to be the same as the roughness of the light-emitting surface 5021. Illustratively, when the light guide structure 50 is manufactured using an injection molding process, the inner surface of the mold cavity has a first surface, a second surface, and a third surface. The first surface is used for forming the light incident surface 5011, the second surface is used for forming the light emergent surface 5021, and the third surface is used for forming the surface of the light guide connecting piece 503, which faces away from the light guide column 501. In order to make the roughness of the light incident surface 5011 smaller than the roughness of the light emergent surface 5021 and smaller than the roughness of the surface of the light guide connecting piece 503 facing away from the light guide column 501, the first surface may be polished, the second surface and the surface of the light guide connecting piece 503 facing away from the light guide column 501 may not be subjected to any treatment, or the second surface and the surface of the light guide connecting piece 503 facing away from the light guide column 501 may be subjected to a frosting treatment. In this way, the roughness of the light incident surface 5011 after molding is smaller than the roughness of the light emergent surface 5021, and smaller than the surface of the light guide connector 503 facing away from the light guide column 501. Also, for example, the first surface may not be polished, but the light-emitting surface 5021 of the molded light guide member 502 and the surface of the light guide connector 503 facing away from the light guide column 501 may be frosted, or the light-entering surface 5011 of the molded light guide column 501 may be polished.

On this basis, the roughness of the surfaces of the light guiding structure 50 except the light-emitting surface 5021 and the surface of the light guiding connecting piece 503 facing away from the light guiding column 501 is smaller than the roughness of the light-emitting surface 5021 and smaller than the roughness of the surface of the light guiding connecting piece 503 facing away from the light guiding column 501. It can be appreciated that the remaining surfaces include a light incident surface 5011. In this way, when the external ambient light enters the light guiding structure 50 through the light incident surface 5011, other surfaces (for example, the surface of the light guiding member 502 facing the screen 10, the surface of the light guiding connecting member 503 facing the inner peripheral surface of the frame 211, etc.) except the light incident surface 5011 have a certain reflection effect, so that the emission of the ambient light from these surfaces can be reduced, thereby being beneficial for more ambient light to be guided to the light emergent surface 5021, and be emitted from the light emergent surface 5021 to the light sensitive surface 301, and further improving the reliability of the light sensing device 30 for detecting the ambient light.

Based on any of the above embodiments, in some embodiments of the present application, please refer to fig. 16 in combination with fig. 14, wherein fig. 16 is a schematic diagram illustrating partial cooperation between the main circuit board 40 and the light guiding structure 50 according to fig. 14. In order to prevent the photosensitive device 30 from being damaged by collision with other structures during transportation or assembly, the electronic apparatus 100 further includes a shielding member 40a. The guard 40a is fixed to the surface of the main circuit board 40 facing the screen 10 and is located at the outer periphery of the photosensitive device 30. The height of the guard 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 protection member 40a can be used to protect the photosensitive device 30, and the arrangement of the protection member 40a does not affect the reception of ambient light by the photosensitive device 30.

On this basis, since the height of the protecting 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 guiding plate 5022, the protecting member 40a and the main circuit board 40 is thickened, and in order to reduce the thickness, the thickness of the whole electronic device 100 is thinned, please refer to fig. 17, and fig. 17 is a perspective view of another view angle of the light guiding structure 50 shown in fig. 14. The surface of the light guide 502 facing the photosensitive device 30 has a relief groove 5024. The avoiding groove 5024 surrounds the light-emitting surface 5021. The escape groove 5024 is provided for escaping the guard 40a. In this way, the avoiding groove 5024 can be utilized to avoid the protecting member 40a, so that one end, adjacent to the screen 10, of the protecting member 40a can be conveniently accommodated in the avoiding groove 5024, the problem of thickness thickening of the protecting member 40a caused by protruding from the photosensitive device 30 is solved, and on the other hand, the thickness dimension of the position, corresponding to the light emitting surface 5021, on the light guide plate 5022 is not too small, so that the light guide effect of the light guide plate 5022 is improved, and more ambient light is facilitated to be emitted to the photosensitive surface 301.

Specifically, with continued reference to fig. 17, the light guide 502 includes a light guide 5022 and a protrusion 5023. The protruding portion 5023 is disposed on a surface of the light guide plate 5022 facing the photosensitive device 30, and the protruding portion 5023 protrudes from the surface of the light guide plate 5022 facing the photosensitive device 30. An end surface of the protruding portion 5023 away from the light guide plate 5022 (i.e., an end surface of the protruding portion 5023 facing the light sensing device 30) forms a light emitting surface 5021. The sides of the protrusions 5023 and the surface of the light guide plate 5022 facing the photosensitive device 30 define the escape grooves 5024. Therefore, the structure is simple, and the processing and the manufacturing are convenient.

Specifically, the shape of the relief groove 5024 is adapted to the shape of the shield 40a, and the shield 40a is formed in a U shape, and the relief groove 5024 is also formed in a U shape, as shown in fig. 16 and 17. Of course, it is understood that, in other examples, the guard 40a may be formed in a closed loop shape, and the avoiding groove 5024 may also be formed in a closed loop shape, so long as the shape of the avoiding groove 5024 is adapted to the shape of the guard 40 a.

Based on any of the above embodiments, in some embodiments of the present application, please continue to refer to fig. 16, and referring to fig. 14, the photosensitive device 30 is located at one end of the main circuit board 40 adjacent to the through hole 211c (where the light guiding pillar 501 is located in fig. 16). And no other electronic components are disposed on the main circuit board 40 in the region between the photosensitive device 30 and the through hole 211 c. In this way, the photosensitive device 30 is advantageously disposed closer to the through hole 211c, and the size of the light guide 502 in the arrangement direction of the photosensitive device 30 and the through hole 211c is reduced, so that the material cost can be saved, and the space occupied by the light guide 502 in the electronic device 100 can be reduced.

With reference to fig. 18, fig. 18 is a schematic diagram illustrating components of the light guiding structure 50 according to fig. 14 in some embodiments of the application. The light guiding structure 50 includes a light transmissive matrix 50a and diffusing particles 50b. The diffusion particles 50b are uniformly distributed in the light-transmitting substrate 50 a. In this way, when the ambient light entering the light guide structure 50 through the light incident surface 5011 is directed to the diffusion particles 50b, scattering, reflection, refraction, and the like are generated, so that more ambient light is advantageously directed to the light emitting surface 5021, the intensity of the ambient light directed from the light emitting surface 5021 to the light sensing surface 301 is further improved, and the viewing angle of the entire light sensing device 30 and the light guide structure 50 is improved.

In addition, according to the actual needs of different products, different parts by weight of diffusion particles 50b can be added into the light guide structure 50 to adjust the transmittance and diffusion effect according to the needs of different products. For example, when the size of the light incident surface in the light guide structure 50 is relatively small, the diffusion particles 50b may be added more appropriately to improve the transmittance and the adjustment of the 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, the diffusion particles 50b may be appropriately added less.

When the light source located on the central axis L1 of the light guiding column 501 is set to emit to the light guiding structure 50, the light intensity of the ambient light collected by the light sensing device 30 is set to V1. The light source is moved in the direction along the circumferential direction of the light incident surface 5011 and parallel to the side (e.g., the first side) where the through hole 211c is located, or in the direction parallel to the light incident surface 5011, or in the direction perpendicular to the central axis L1 of the light guide pillar 501, and when the light source is moved to a position where the light intensity of the ambient light collected by the light sensing device 30 is 0.5V1, an angle between a 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 pillar 501 is an angle of view. Wherein, the vertical distance between the light source and the light incident surface is 50cm.

Illustratively, the field angle has a value in the range of 34 to 50 °.

Illustratively, 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.

For example, when the light-transmitting substrate 50a is made of polycarbonate, the off-white polycarbonate has good diffusion effect on visible light, the angle of view is larger, the reporting values of different angles are continuous, the problem of abrupt change of the reporting values is avoided, the front light source of the screen 10 can be accepted as far as possible, and the design accords with the design of human eyes.

Illustratively, in 100 parts by weight of the light guide structure 50, the diffusion particles 50b are 40 to 60 parts by weight. In this way, the ambient light entering the light guide structure 50 through the light incident surface 5011 is scattered, reflected, refracted, and the like when it is directed to the diffusion particles 50b, so that more ambient light is advantageously directed to the light emergent surface 5021, and the intensity of the ambient light directed from the light emergent surface 5021 to the light sensitive surface 301 is improved.

In the embodiment in which any of the light guide structures 50 includes the light-transmitting matrix 50a and the diffusion particles 50b, the light guide structure 50 has a value of the light transmittance of light having a wavelength of 550nm in a range of 35% to 55%. For example, the light transmittance is 45%. Therefore, the light guide effect is good.

It should be noted that the light transmittance refers to the ratio of the light intensity transmitted through the material to the original light intensity.

On the basis of any of the above embodiments, referring back to fig. 13 and 14, a through hole 211c is formed on the first side 2115. In particular, referring to fig. 19, fig. 19 is a scene diagram of a user using the electronic device 100. As shown in fig. 19, when the user uses the electronic device 100, the user is often faced to the display surface of the display screen 12, and one end of the bezel 211 having the sound emitting hole 211b faces upward. By providing the through hole 211c on the first side 2115, the through hole 211c can be provided close to the sound outlet hole 211b. In this way, when the user uses the electronic device 100, the through hole 211c faces upward, and the light source is generally located above the user, so as to be closer to the light intensity contacted by the eyes of the user, so that more ambient light above the user can be conveniently directed to the position of the through hole 211c, which is beneficial to improving the accuracy of detecting the ambient light by the photosensitive device 30. In addition, the through holes 211c and the sound outlet holes 211b are arranged together, so that the structure is simple, attractive, and not easy to be shielded. Of course, it is understood that in other examples, the through-holes 211c may also be formed on portions of the second side 2116 and the fourth side 2118 adjacent the first side 2115.

With continued reference to fig. 19, in addition to any of the above embodiments, when the user uses the electronic device 100, the user may tilt the electronic device 100 with respect to the user's face by an angle β in a direction from the user's chest to the user's head toward a direction away from the user's face for ease of viewing. As previously described, the perceived impact or stimulus of the user's eyes is different over different brightness ranges. Considering that the ambient light intensity between the face of the user and the display surface of the electronic device 100 is closer to the ambient light intensity actually sensed by the eyes of the user, if the ambient light intensity detected by the ambient light sensor is consistent with the ambient light intensity actually sensed by the eyes of the user, the brightness of the screen 10 can be adjusted by combining the ambient light intensities to adjust the brightness of the screen 10 to a comfortable brightness range or an acceptable brightness range of the user using the electronic device 100, so that the reliability of adjusting the brightness of the screen 10 is improved. However, when the electronic device 100 is inclined by a certain angle β relative to the face of the user in a direction from the chest of the user to the head of the user toward a direction away from the face of the user, the through hole 211c on the first side 2115 is further away from the user, resulting in that the ambient light intensity detected by the photosensitive device deviates from the ambient light intensity between the face of the user and the display surface of the electronic device 100, and thus, the light intensity of the ambient light actually perceived by the eyes of the user deviates, and there is a case where the ambient light sensor reading is inaccurate (may be low).

Based on this, in order to solve the technical problem, in this embodiment, the current posture of the electronic device 100 is taken into consideration as one factor for adjusting the brightness of the screen 10. Referring to fig. 20 and 21, fig. 20 is a schematic diagram showing electrical connection among the processor, the screen 10, the gesture detection device and the photosensitive device 30 in the electronic apparatus 100 shown in fig. 13 and 14, and fig. 21 is a schematic diagram showing control of brightness adjustment of the screen 10 by the processor in the electronic apparatus 100 shown in fig. 20. The electronic device 100 further comprises a gesture detection means. The processor, the posture detecting device, the photosensitive device 30 and the screen 10 are all electrically connected. Illustratively, the gesture detection device is secured to the main circuit board 40 so as to be electrically connected to a processor located on the main circuit board 40 through the main circuit board 40. Of course, the posture detecting device may be fixed to the sub-circuit board 80.

With continued reference to fig. 21, the gesture detection device is configured to output angle information, where the angle information is used to indicate an angle a between the current gesture of the electronic device 100 and the horizontal plane (in conjunction with fig. 19). Specifically, since the frequency of using the electronic device 100 in the sitting position of the user is highest, and the frequency of using the electronic device 100 in the vertical screen of the user is often higher than that of using the electronic device 100 in the horizontal screen of the user, in order to improve the accuracy of adjusting the brightness of the screen 10, and in order to simplify the control logic of the electronic device 100, determining the angle a between the current posture of the electronic device 100 and the horizontal plane refers to 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.

For example, the gesture detection device may comprise an acceleration sensor and/or a gyro sensor. The acceleration sensor may detect the magnitude of acceleration of the electronic device 100 in various directions (typically three axes). When the gesture of the electronic device 100 is different, the gravity accelerations detected on the coordinate axes of the acceleration sensor are different, and the included angle between the coordinate axes and the gravity direction can be obtained according to the force decomposition principle by using the measurement results of the directions. Therefore, the angular rotation relationship between the acceleration sensor coordinate system and the geographic coordinate system can be obtained by measuring the included angles between each axis and the gravity direction in the acceleration sensor coordinate system in the electronic equipment 100, so that the gesture of the electronic equipment 100 is known. The gyroscopic sensor may determine the angular velocity of the electronic device 100 about three axes. As the path can be calculated by integrating the velocity with respect to time, the "angle" rotated by the electronic device can be calculated by integrating the angular velocity with respect to time and can be used to determine the motion gesture of the electronic device 100. It is understood that the three-axis coordinates in the gesture detection device may be the same as or different from the XYZ three-axis coordinate system defined herein for the thickness and length and width of the electronic device 100.

The light sensing device 30 is configured to output light intensity information indicating the intensity of ambient light in the current environment in which the electronic apparatus 100 is located.

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

In this way, the ambient light intensity in the current environment where the electronic device 100 is located and the included angle a between the current gesture and the horizontal plane of the electronic device 100 can be combined, the ambient light in the current environment where the electronic device 100 is located detected by the photosensitive device 30 is compensated by using the included angle information, which is beneficial to improving the accuracy of the processor for adjusting the brightness of the screen 10 and is convenient for the user to use.

In some embodiments, referring to fig. 22, fig. 22 is another control schematic diagram of the brightness adjustment of the screen 10 according to the processor in the electronic device 100 shown in fig. 20. The processor is configured to generate, when an included angle a between a current gesture of the electronic device 100 and a horizontal plane is within a preset included angle range, first control information according to the light intensity information and the included angle information specifically includes: the processor is configured to generate compensation information according to the light intensity information and the angle information when the angle a between the current gesture of the electronic device 100 and the horizontal plane is within a preset angle range. The compensation information is used to indicate the intensity of the ambient light that needs to be compensated. The processor is further configured to generate correction information based on the compensation information and the light intensity information. The correction information is used to indicate a corrected ambient light intensity. The processor generates first control information according to the correction information so that the processor adjusts the brightness of the screen 10 according to the correction information.

It is understood that the modified ambient light intensity is greater than the ambient light intensity in the current environment in which the electronic device 100 is located.

In this way, accurate compensation information is generated according to the included angle information and the light intensity information, and further accurate correction information is generated according to the compensation information and the light intensity information, so that accuracy of brightness adjustment of the screen 10 by the processor is improved, and convenience is brought to users.

For example, referring back to fig. 19, when the electronic device 100 is tilted at an angle β with respect to the face of the user in a direction from the chest of the user to the head of the user toward a direction away from the face of the user, the β value is generally not too large for ease of viewing. At this time, the angle a between the current posture of the electronic device 100 and the horizontal plane is not too large. The preset included angle range is [ -45 deg., 45 deg. ] in consideration of the accuracy of the brightness adjustment of the screen 10. Thus, the processor is beneficial to generating accurate compensation information, and the accuracy of adjusting the brightness of the screen 10 is further improved.

Specifically, referring to fig. 23, fig. 23 is a schematic diagram illustrating still another control of the brightness adjustment of the screen 10 according to the processor in the electronic device 100 shown in fig. 20. Ambient light intensity L to be compensated _Compensation The following formula is satisfied:

L _compensation ＝L ₀ *(45-|A|)*(45-|A|)*C。

Wherein L is ₀ Is the ambient light intensity corresponding to the light intensity information. A is the angle between the current pose of the electronic device 100 and the horizontal plane. C is a constant. That is, C is a preset compensation coefficient. The C value may be a value preset before shipping the electronic device 100. The value may be set by the user according to actual needs. Illustratively, C has a value of 0.001, 0.002, 0.003, 0.004, 0.005 or 0.006.

In this way, the ambient light intensity to be compensated corresponding to the reinforcement information generated by the formula is more accurate, which is beneficial to improving the accuracy of the processor in adjusting the brightness of the screen 10 and is convenient for users to use.

Specifically, the corrected ambient light intensity L _{Repair tool} The following formula is satisfied:

L _correction ＝L ₀ +L _Compensation 。

The corrected ambient light intensity is the sum of the ambient light intensity to be compensated and the ambient light intensity corresponding to the light intensity information.

In this way, the correction information generated by the formula is more accurate, which is beneficial to improving the accuracy of the processor for adjusting the brightness of the screen 10 and is convenient for users to use.

On the basis of any of the above embodiments, in some embodiments, when the processor determines that the included angle a between the current posture of the electronic device 100 and the horizontal plane is not within the preset included angle range, the processor generates the 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.

For example, when the processor determines that the angle a between the current gesture of the electronic device 100 and the horizontal plane is not within the preset angle range, the processor directly generates the 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.

For further example, for facilitating simplification of the screen brightness control method, referring to fig. 23, when the processor determines that the included angle a between the current gesture of the electronic device 100 and the horizontal plane is not within the preset included angle range, the processor generates the second control information according to the light intensity information specifically includes: 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, i.e. L as described above _Compensation Is 0.
