[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] In the related art, electronic devices such as smartphones can obtain the user's facial features by setting up structured light components, and then perform operations such as user authentication. Usually, the structured light component is set on the front of the electronic device for the convenience of users. The front of the electronic device is usually equipped with a display screen, and in order to pursue a larger screen-to-body ratio effect, the area of ​​the display screen is large, which creates a certain conflict with the setting of the structured light component. Some electronic devices use the method of digging holes under the display screen to set up the structured light component. This setting method may affect the viewing effect of the display screen due to the large opening area.

[0018] Based on this, the inventor of the present application proposes an electronic device 10 in order to improve the above technical problems. The following is a detailed description in conjunction with specific embodiments and drawings:

[0019] Figure 1 as well as Figure 2An electronic device 10 is shown, which includes a housing 20, a display screen assembly 30, a cover plate 60 and a structured light assembly 40, wherein the display screen assembly 30 and the cover plate 60 are arranged on the housing 20, and the structured light assembly 40 is used to collect facial feature information of the user.

[0020] Please also refer to and Figure 2 and Figure 3 The housing 20 includes a front housing 23, a middle frame 22 and a rear housing 21, wherein the front housing 23 and the rear housing 21 are respectively mounted on opposite sides of the middle frame 22, the front housing 23 is used to mount a display screen, and the accommodation space formed between the rear housing 21 and the middle frame 22 can be used to install various components of the electronic device 10, such as a motherboard 80, a battery 90, etc. In this embodiment, a fixing hole 24 is provided on the rear housing 21, and the fixing hole 24 can penetrate the rear housing 21. The fixing hole 24 can be used to set a rear camera, and the rear camera can be exposed from the fixing hole 24 to perform image acquisition.

[0021] The structured light component 40 is electrically connected to the mainboard 80 and the battery 90. The battery 90 can supply power to the mainboard 80 and the structured light component 40. The mainboard 80 is integrated with one or more processors and memories. The processor uses various interfaces and lines to connect various parts of the entire electronic device 10. By running or executing instructions, programs, code sets or instruction sets stored in the memory, and calling data stored in the memory, the processor performs various functions of the electronic device 10 and processes data. Optionally, the processor can use digital signal processing (DSP), field programmable gate array (FPGA), programmable logic array (FPGA), etc. The processor may be integrated with one or more of the following hardware forms: a central processing unit (CPU), a graphics processing unit (GPU), and a modem. The CPU mainly processes the operating system, user interface, and application programs; the GPU is responsible for rendering and drawing display content; and the modem is used to process wireless communications. It is understandable that the above-mentioned modem may not be integrated into the processor, but may be implemented separately through a communication chip.

[0022] The memory may include a random access memory (RAM) or a read-only memory (ROM). The memory may be used to store instructions, programs, codes, code sets or instruction sets. The memory may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as a touch function, a sound playback function, an image playback function, etc.), instructions for implementing the following various method embodiments, etc. The data storage area may also store data (such as a phone book, audio and video data, chat record data) created by the electronic device 10 during use.

[0023] The memory may store one or more control instructions for the structured light component 40 , and the processor may call the control instructions to control the structured light component 40 to work.

[0024] It is understandable that the front shell 23 and the rear shell 21 can be made of various materials such as metal, plastic, glass, ceramic, etc., and the front shell 23 and the rear shell 21 can be made of the same material or different materials, which is not limited here. The housing 20 has a first side and a second side opposite to each other, wherein the first side refers to the side of the front shell 23 of the housing 20, and the second side refers to the side of the housing 20 close to the rear shell 21.

[0025] See also Figure 4 The middle frame 22 includes a middle plate 222 and a frame 221. The frame 221 is arranged around the edge of the middle plate 222, and the frame 221 protrudes from the middle plate 222. The frame 221 protrudes from the middle plate 222 on both sides of the middle plate 222. The rear shell 21 is assembled on one side of the middle plate 222, and the rear shell 21 and the frame 221 are assembled and fixed. The rear shell 21 and the middle frame 22 jointly form a receiving cavity, and various components such as the mainboard 80, the battery 90, and the microphone can be arranged in the receiving cavity.

[0026] The battery 90 and the main board 80 are both disposed in the accommodating cavity and can be carried by the middle board 222 and covered and protected by the rear shell 21. The battery 90 is electrically connected to the main board 80 to control the battery 90 to supply power to other functional components or obtain information such as the power of the battery 90.

[0027] The display screen assembly 30 is mounted on the frame 221, and the display screen assembly 30 is opposite to the middle plate 222, and the display screen assembly 30 is located on the side of the middle plate 222 away from the rear housing 21. The area of ​​the display screen assembly 30 can be roughly equivalent to the area of ​​the middle plate 222. The display screen assembly 30 can use an LCD (Liquid Crystal Display) screen to display information, and the LCD screen can be a TFT (Thin Film Transistor) screen or an IPS (In-Plane Switching) screen or an SLCD (Splice Liquid Crystal Display) screen. In other embodiments, the display screen assembly 30 can use an OLED (Organic Light-Emitting Diode) screen to display information. The OLED screen can be an AMOLED (Active Matrix Organic Light Emitting Diode) screen or a Super AMOLED (Super Active Matrix Organic Light Emitting Diode) screen or a SuperAMOLED Plus (SuperActive Matrix Organic Light Emitting Diode Plus, Magic Screen) screen, which will not be repeated here.

[0028] Please continue reading Figure 4 The cover plate 60 is arranged above the display screen assembly 30, that is, the cover plate 60 is located on the surface of the display screen assembly 30 away from the middle plate 222, and is used to protect the display screen assembly 30. The area of ​​the cover plate 60 can be larger than the area of ​​the display screen assembly 30 to provide better protection for the display screen assembly 30.

[0029] Specifically, the cover plate 60 includes a light incident surface 62 and a light emitting surface 61 facing each other. The light incident surface 62 is the surface of the cover plate 60 facing the display screen assembly 30, and the light emitting surface 61 is the surface of the cover plate 60 away from the display screen assembly 30. The light incident surface 62 includes a display area 63 and a non-display area 63 surrounding the display area 63, wherein the display area 63 corresponds to the display screen assembly 30, and the non-display area 63 surrounds the display area 63 and is staggered from the display screen assembly 30. When the display screen assembly 30 is stimulated to work, the image light formed is projected outward through the display area 63, and the user can watch the image formed in the display area 63, and can also interact with the display screen assembly 30 by touching and pressing the light emitting surface 61 of the cover plate 60. The non-display area 63 can be assembled on the frame 221 to fix the cover plate 60. The cover plate 60 is made of a light-transmitting material, such as glass or light-transmitting plastic, which is not limited in this embodiment.

[0030] In this embodiment, please continue to refer to Figure 4 A mounting step 223 is provided on one side of the frame 221 close to the middle plate 222. The mounting step 223 is substantially flush with the display screen assembly 30. The display area 63 of the cover plate 60 covers the display screen assembly 30. At least a portion of the non-display area 63 overlaps the mounting step 223 to form a fixed portion. Glue can be dispensed on the mounting step 223 to bond and fix the cover plate 60 and the frame 221. There is a gap 71 between the display screen assembly 30 and the mounting step 223, wherein the width of the gap 71 can be, for example, 1.0 mm to 1.5 mm.

[0031] Please combine Figure 2 and Figure 4 The structured light component 40 includes a transmitting component 41 and a receiving component 42. The transmitting component 41 is used to transmit a light beam. When the light beam encounters an obstacle, it is reflected. The reflected light beam can be received by the receiving component 42. Then, according to the time difference between the emission and reception of the light beam and the intensity change, the characteristic information of the obstacle is obtained, and the depth image information of the obstacle is generated. Specifically, in this embodiment, the light beam emitted by the transmitting component 41 can be an infrared laser, and the receiving component 42 receives the reflected infrared laser.

[0032] The transmitting assembly 41 includes an emitter 411 and a light guide 412. The light guide 412 is attached to the non-display area 63. The emitter 411 is used to emit a light beam toward the light guide 412, that is, the light beam emitted by the transmitting assembly 41 is projected outward from the non-display area 63 of the cover plate 60. Specifically, the light guide 412 can be bonded to the non-display area 63 by a light-transmitting adhesive, wherein the size of the light guide 412 is smaller than the size of the non-display area 63, and the light guide 412 is arranged in the gap 71. This embodiment does not increase the space requirement in the electronic device 10, nor does it need to open a through hole corresponding to the light guide 412 on the display screen assembly 30, thereby increasing the screen-to-body ratio.

[0033] In one embodiment, the light incident surface 62 of the cover plate 60 may be a complete plane, and the light guide 412 is directly attached to a predetermined position of the light incident surface 62. The emitter 411 may be disposed below the light guide 412, for example, corresponding to the light guide 412. At this time, the optical axis direction of the light beam emitted by the emitter 411 is perpendicular to the cover plate 60, that is, the light beam emitted by the emitter 411 is directly incident on the light guide 412 in a direction perpendicular to the cover plate 60. The light guide 412 may diffuse and shape the light beam emitted by the emitter 411, and adjust the light spot (optical extension) of the light beam and the brightness of each point on the light spot. The light guide 412 may be, for example, a diffuser for diffusing light. The field of view of the light beam is adjusted, thereby improving the image quality of the emitted light beam when acquiring a depth image.

[0034] In order to ensure that the light guide 412 and the emitter 411 are not easily damaged during the installation process, and to ensure that the light beam emitted by the light guide 412 has a suitable viewing angle when the light guide 412 is working, the gap 71 between the light guide 412 and the display screen assembly 30 can be greater than or equal to 0.4 mm, which can prevent interference or collision with the display screen assembly 30 during the assembly of the light guide 412 to avoid damage, and the light beam emitted from the light guide 412 has a suitable viewing angle. At the same time, the gap 71 between the light guide 412 and the installation step 223 can be greater than or equal to 0.2 mm. Since the structured light component 40 is usually arranged on the top of the electronic device 10, in this arrangement, the gap 71 between the light guide 412 and the display screen component 30 is larger than the gap 71 between the light guide 412 and the mounting step 223. Therefore, when the light guide 412 emits a light beam, it can have a larger field of view angle on the side close to the display screen component 30. When the user uses the electronic device 10, the user's eyes usually look at the top of the electronic device 10 (such as the front camera area). At this time, the light guide 412 has a larger field of view angle on the side close to the display screen component 30, and the light beam emitted by the emitting component 41 can cover more areas of the user's face, thereby improving the quality of the collected depth image.

[0035] In order to further reduce the space occupied by the launch assembly 41, in one embodiment, refer to Figure 5 , a surface of the light guide 412 away from the cover plate 60 is provided with a groove 415, the groove 415 corresponds to the emitter 411, and the width of the groove 415 is larger than the size of the emitter 411, and the emitter 411 is at least partially located in the groove 415, so that the size of the entire emitting component 41 in the thickness direction can be compressed, thereby reducing the space occupied. Preferably, the emitter 411 is integrally embedded in the groove 415 and connected to the main board 80 via a flexible circuit board. The groove 415 can be pre-processed by the light guide 412, and the groove 415 can be a rectangular groove, a cylindrical groove, etc. In this embodiment, refer to Figure 6 The light guide 412 includes a bottom wall 4123 and a side wall 4124 that form a groove 415. The bottom wall 4123 is substantially parallel to the light incident surface 62 of the cover plate 60. The side wall 4124 is connected to the bottom wall 4123. The side wall 4124 can be in a rectangular, circular or other shape, which is not limited in this embodiment. Since the light guide 412 is mostly made of glass, during the processing, the bottom wall 4123 and the side wall 4124 in the groove 415 need to be as smooth as possible to prevent the light beam from being deflected on the side wall 4124 or the bottom wall 4123.

[0036] For ease of installation, the size of the groove 415 should be appropriately larger than the size of the emitter 411. In the process of the emitter 411 emitting a light beam, since the light beam may have a collimation problem, most of the light in the light beam is emitted toward the bottom wall 4123 and passes through the light guide 412, while part of the light in the light beam may be emitted toward the side wall 4124. After entering the light guide 412, this part of the light may be emitted from the side of the light guide 412, forming a light leakage phenomenon, causing light loss, and may affect the acquired depth image effect. Therefore, in one embodiment, a reflective layer 416 can be provided on the side wall 4124. The reflective layer 416 can be a metal plating layer or film layer formed by a metal such as silver (Ag). In this way, when the light in the light beam is incident on the side wall 4124, it will be reflected by the reflective layer 416. Since the light has a certain incident angle when it is incident on the reflective layer 416, it will be reflected toward the bottom wall 4123 when it is reflected, and then emitted from the bottom wall 4123, and then used.

[0037] In another embodiment, please refer to Figure 6The bottom wall 4123 includes a first area 4125 and a second area 4126, wherein the second area 4126 surrounds the first area 4125 and is adjacent to the side wall 4124, and the second area 4126 is also provided with a reflective layer 416, wherein a radial dimension R1 of the first area 4125 is 120%-130% of a radial dimension of the emitter 411, wherein the radial dimension refers to a radial dimension with the center of the bottom wall 4123 as the center of the circle, and the optical axis center of the emitter 411 coincides with the center of the first area 4125 when assembled. The advantage of this arrangement is that the groove 415 can be opened larger than the emitter 411, which is beneficial to the processing of the light guide 412 and easy to assemble; at the same time, among the light beams emitted by the emitter 411, when part of the light beam is incident on the side wall 4124 or the second area 4126, or is reflected to the second area 4126 by the reflective layer 416 arranged in the second area 4126, it will be reflected again by the reflective layer 416 arranged in the second area 4126, and the reflected light is reflected multiple times by the reflective layer 416 in the groove 415, and finally emitted from the first area 4125. When the light beam entering the light guide 412 from the first area 4125 passes through the light guide 412, the field of view angle can be controlled by the light guide 412, thereby controlling the field of view angle of the light beam after passing through the light guide 412, so that the light beam emitted by the emitting component 41 is emitted with a better field of view angle, which is beneficial to obtaining a better quality depth image.

[0038] In another embodiment, see Figure 7 , the emitter 411 can be arranged below the light guide 412, for example, corresponding to the light guide 412. At this time, the optical axis direction of the light beam emitted by the emitter 411 is arranged perpendicular to the cover plate 60, that is, the light beam emitted by the emitter 411 is directly incident on the light guide 412 in a direction perpendicular to the cover plate 60. The light guide 412 includes a diffuser 4122 and a collimator 4121 that are integrated. The collimator 4121 is configured into a roughly hemispherical structure. The diffuser 4122 is attached to the light incident surface 62. The lens portion faces the emitter 411 and is used to collimate the light beam emitted by the emitter 411. The collimated light beam enters the diffuser 4122. The diffuser 4122 diffuses and shapes the light beam, and adjusts the light spot (optical etendue) of the light beam and the light brightness of each point on the light spot. Due to the pre-collimation, the light beam emitted by the emitter 411 can be emitted at a better field of view, which is conducive to obtaining a better depth image.

[0039] In another embodiment, the light guide 412 can also be a micro lens array (Micro Lens Array, MLA), and is integrally mounted on the non-display area 63. The micro lens array is an array composed of lenses with a light aperture and a relief depth of micrometer level. It not only has the basic functions of traditional lenses such as focusing and imaging, but also has the characteristics of small unit size and high integration, so that it can complete functions that traditional optical components cannot complete.

[0040] In another embodiment, see Figure 8 , the light beam emitted by the emitter 411 can be roughly parallel to the light incident surface 62 of the cover plate 60, and the emitting assembly 41 also includes a reflector 413, which is arranged on the optical path of the light beam emitted by the emitter 411 and is used to reflect the light beam into the light guide 412. At this time, the emitter 411 can use an edge-emitting laser, and the reflector 413 can be a right-angle prism, a reflector, etc., which is not specifically limited in this embodiment. The reflecting surface of the reflector 413 can be 45° relative to the light beam emitted from the emitter 411. The light beam reflected by the reflector 413 is incident on the light guide 412 in a direction perpendicular to the light incident surface 62 of the cover plate 60, and then passes through the light guide 412 and the cover plate 60 and then exits.

[0041] Please also read Figure 4-Figure 8 In each embodiment of the present invention, the ink layer 70 covers the non-display area 63 except the light guide 412. The ink layer 70 can shield the non-display area 63 to prevent the image light of the display screen assembly 30 from being exposed from the non-display area 63 and causing light leakage. At the same time, the ink layer 70 can produce a certain shielding effect on the infrared laser emitted by the emitting assembly 41 to prevent the light beam emitted by the emitting assembly 41 from being emitted from other non-display areas 63. In this embodiment, the light guide 412 is attached to the non-display area 63 of the light incident surface 62, and the ink layer 70 is not set in the area where the light guide 412 is set. Therefore, the light beam emitted by the emitting assembly 41 will not be affected by the ink layer 70, which can improve the utilization rate and light efficiency of the light beam.

[0042] Please refer again Figure 1The display screen assembly 30 is also provided with a through hole, and the position of the through hole is adjacent to the frame 221, wherein the through hole can be a circular hole, a rectangular hole, a bar hole, a waist-shaped hole, etc., which is not limited in this embodiment. The receiving component 42 is arranged below the display screen assembly 30 and is carried on the middle plate 222, and the receiving component 42 corresponds to the through hole to receive the light beam reflected by the external object entering the through hole, and the light beam is emitted by the transmitting component 41. In this embodiment, since the through hole only needs to correspond to the receiving component 42, the opening area of ​​the through hole can be smaller, thereby making the actual display area of ​​the display screen larger and improving the screen-to-body ratio. The electronic device 10 can also be provided with a front camera, and the through hole can also correspond to the front camera, and the front camera can capture images through the through hole.

[0043] The working principle of the structured light component 40 provided in this embodiment is: the emitter 411 in the transmitting component 41 emits an infrared laser, and the light beam is shaped and diffused through the light guide 412 to be adjusted into a detection beam with a suitable field of view angle and light intensity. When the detection beam is irradiated to the user's face or eyes, it is reflected, and the reflected detection beam is received by the receiving component 42, thereby obtaining the user's facial depth image.

[0044] The electronic device 10 provided in this embodiment arranges the light guide 412 in the emitting component 41 of the structured light component 40 below the non-display area 63 of the cover plate 60 so that the light beam emitted by the emitting component 41 is emitted from the non-display area 63 of the cover plate 60. Therefore, there is no need to punch a hole in the display area of ​​the cover plate 60 corresponding to the emitting component 41. Therefore, the punching area of ​​the display screen component 30 can be reduced, thereby improving the display effect of the display screen component 30.
