Referring to fig. 2 and 3, the output module 10 is a single package structure, and the output module 10 includes a package housing 11, a structured light projector 12 and a proximity infrared lamp 13.

The package housing 11 is used to package the structured light projector 12 and the proximity infrared lamp 13 at the same time, or the structured light projector 12 and the proximity infrared lamp 13 are packaged in the package housing 11 at the same time. The package housing 11 includes a package substrate 111, a package sidewall 112, and a package top 113. The package housing 11 may be made of an Electromagnetic Interference (EMI) shielding material to prevent external EMI from affecting the output module 10.

The package substrate 111 is used to carry the structural light projector 12 and the proximity infrared lamp 13. In manufacturing the output module 10, the structured light projector 12 and the proximity infrared lamp 13 may be formed on one chip 14, and then the structured light projector 12, the proximity infrared lamp 13, and the chip 14 may be provided together on the package substrate 111, specifically, the chip 14 may be bonded on the package substrate 111. Meanwhile, the package substrate 111 may also be used to connect with other components of the electronic device 100 (e.g., the housing 20 and the motherboard of the electronic device 100), so as to fix the output module 10 in the electronic device 100.

An encapsulation sidewall 112 may be disposed around the structured light projector 12 and the proximity infrared lamp 13, the encapsulation sidewall 112 extending from the encapsulation substrate 111, the encapsulation sidewall 112 may be bonded with the encapsulation substrate 111. Preferably, the package side walls 112 are detachably connected to the package substrate 111 to facilitate maintenance of the structured light projector 12 and the proximity infrared lamp 13 after removal of the package side walls 112. The package side walls 112 may be made of an infrared opaque material to prevent infrared light emitted by the structured light projector 12 or the proximity infrared lamp 13 from passing through the package side walls 112.

The package top 113 is opposite to the package substrate 111, and the package top 113 is connected to the package sidewall 112. The package top 113 is formed with a structured light window 1131 and a proximity window 1132, the structured light window 1131 corresponds to the structured light projector 12, and structured light (infrared light) emitted by the structured light projector 12 passes through the structured light window 1131; the proximity window 1132 corresponds to the proximity infrared lamp 13, and infrared light emitted from the proximity infrared lamp 13 passes out of the proximity window 1132. The package top 113 and the package side wall 112 may be formed integrally or separately. In one example, the structured light window 1131 and the proximity window 1132 are through holes and the package top 113 is made of an infrared opaque material. In another example, the package top 113 is made of an infrared opaque material and an infrared opaque material, specifically, the structured light window 1131 and the proximity window 1132 are made of an infrared opaque material, and the rest of the package top is made of an infrared opaque material, further, the structured light window 1131 and the proximity window 1132 may be formed with a lens structure to improve the emission angle of infrared light emitted from the structured light window 1131 and the proximity window 1132, for example, the structured light window 1131 is formed with a concave lens structure to make light passing through the structured light window 1131 diverge and emit outwards; the proximity window 1132 is formed with a convex lens structure to focus light passing through the proximity window 1132 to be emitted outward.

The structured light projector 12 and the proximity infrared lamp 13 can be formed on a chip 14, the volume of the structured light projector 12 and the proximity infrared lamp 13 after integration is further reduced, and the manufacturing process is simple. The structured light projector 12 can emit structured light outwards, the structured light can form an infrared laser speckle pattern, the structured light is projected onto the surface of the target object, the structured light pattern modulated by the target object is collected by the infrared camera 62 (as shown in fig. 1), and a depth image of the target object is obtained by analyzing and calculating the modulated structured light pattern (at this time, the structured light projector 12 is used for stereo imaging). In an embodiment of the present invention, the structured light projector 12 includes a projector light source 121, a frame 122, a projector lens 123, and a Diffractive Optical Elements (DOE) 124. The light beam emitted from the projector light source 121 is collimated or converged by the projector lens 123, expanded by the diffractive optical element 124, and emitted outward in a certain beam pattern. Specifically, the projector light source 121 may be formed on the chip 14, and the projector lens 123 and the diffractive optical element 124 may be fixed to the frame 122, for example, by gluing to the frame 122. The proximity infrared lamp 13 may emit infrared light, which passes through the proximity window 1132 and reaches the surface of the object, and the proximity sensor 51 (shown in fig. 7) of the electronic device 100 receives the infrared light reflected by the object to detect the distance of the object to the electronic device 100 (at this time, the proximity infrared lamp 13 is used for infrared ranging).

The structured light projector 12 and the proximity infrared lamp 13 can emit infrared light to the outside of the packaging shell 11 at different powers, specifically, the structured light projector 12 and the proximity infrared lamp 13 can emit infrared light at the same time, and the output module 10 is used for three-dimensional imaging and infrared distance measurement at the same time; or the structured light projector 12 can emit light rays but not emit light rays near the infrared lamp 13, and the output module 10 is only used for stereo imaging; alternatively, the structured light projector 12 may not emit light and emit light near the infrared lamp 13, and the output module 10 is only used for infrared distance measurement. Referring to fig. 4, in the embodiment of the invention, the output module 10 is formed with a ground pin 15, a structured light pin 16 and a proximity light pin 17. A ground pin 15, a structured light pin 16, and a proximity lamp pin 17 may be formed on the package substrate 111, and the structured light projector 12 emits infrared light when the ground pin 15 and the structured light pin 16 are enabled (i.e., when the ground pin 15 and the structured light pin 16 are connected into a circuit and turned on); when the ground pin 15 and the proximity lamp pin 17 are enabled (i.e., when the ground pin 15 and the proximity lamp pin 17 access circuit are on), the proximity infrared lamp 13 emits infrared light; when the ground pin 15, the structured light pin 16, and the proximity lamp pin 17 are enabled (i.e., when the ground pin 15, the structured light pin 16, and the proximity lamp pin 17 access circuit are on), the structured light projector 12 emits infrared light, and the proximity infrared lamp 13 emits infrared light.

Referring to fig. 1 and 5, the housing 20 may serve as a mounting carrier for the output module 10, or the output module 10 may be disposed in the housing 20. The housing 20 includes a top portion 21 and a bottom portion 22, the top portion 21 is located above the bottom portion 22 in a state that the user normally uses the electronic device 100, and the output module 10 is disposed between the top portion 21 and the bottom portion 22 as shown in fig. 1. Referring to fig. 6, the housing 20 is provided with a mounting groove 25, and the mounting groove 25 is formed between the top 21 and the bottom 22. The chassis 20 may be a middle or outer shell of the electronic device 100.

Referring to fig. 6, the display screen 90 is disposed on the housing 20 and closes the mounting groove 25 to form a closed mounting space. The display panel 90 is formed with a transparent solid area 91 and a non-transparent area 94, the transparent solid area 91 does not include image pixels and is surrounded by a plurality of image pixels, the image pixels are distributed in the non-transparent area 94, in other words, the non-transparent area 94 is a display area of the display panel 90, and the non-transparent area 94 is used for realizing the display function of the display panel 90. The material of the light-transmissive solid region 91 includes, but is not limited to, glass. Light outside the electronic device 100 can enter the electronic device 100 through the light-transmissive solid region 91 without destroying the integrity of the display screen 90. The display screen 90 includes a front surface 92 capable of displaying a picture and a rear surface 93 opposite to the front surface 92. Specifically, when the display screen 90 emits light and displays a picture, the light emitted from the display screen 90 exits the display screen 90 from the front surface 92; when the display screen 90 is mounted to the housing 20, the mounting slot 25 and the front 92 are located on opposite sides of the back 93 (i.e., the back 93 is located between the front 92 and the mounting slot 25). In the embodiment of the present invention, the output module 10 may be disposed between the edge of the display screen 90 and the top 21, and since the output module 10 according to the embodiment of the present invention may occupy a smaller volume, the volume for disposing the display screen 90 in the housing 20 may be correspondingly increased to increase the screen occupation ratio of the electronic device 100. In other embodiments, the display screen 90 may be a full screen with a gap, the display screen 90 surrounds the output module 10, and the output module 10 is exposed from the gap of the display screen 90. In some embodiments, the light transmissive solid region 91 is equal in thickness and continuous with the surrounding non-light transmissive region 94.

Referring to fig. 1 and 5, the housing 20 further has a housing access through hole 23 and a housing structure optical through hole 24. When the output module 10 is disposed in the housing 20, the proximity infrared lamp 13 corresponds to the housing proximity through hole 23, and the structured light projector 12 corresponds to the housing structured light through hole 24. The light emitted by the near infrared lamp 13 corresponding to the case near through hole 23 can pass through the case near through hole 23, specifically, the near infrared lamp 13 is opposite to the case near through hole 23, or the light emitted by the near infrared lamp 13 passes through the case near through hole 23 after being acted by the light guide element. The structured light projector 12 corresponds to the housing structured light through hole 24, and the description thereof is omitted here. In the embodiment shown in fig. 5, the chassis access opening 23 and the chassis structure optical opening 24 may be spaced apart from each other, but of course, in other embodiments, the chassis access opening 23 and the chassis structure optical opening 24 may be in communication with each other.

The cover plate 30 may be light-transmissive, and the material of the cover plate 30 may be light-transmissive glass, resin, plastic, or the like. The cover plate 30 is disposed on the chassis 20, the cover plate 30 includes an inner surface 32 combined with the chassis 20, and an outer surface 31 opposite to the inner surface 32, and the light emitted from the output module 10 sequentially passes through the inner surface 32 and the outer surface 31 and then passes through the cover plate 30. In the embodiment shown in fig. 5, the cover plate 30 covers the chassis structure light through hole 24 and the chassis approach through hole 23, the inner surface 32 of the cover plate 30 is coated with the infrared transmissive ink 40, and the infrared transmissive ink 40 has a high transmittance to infrared light, for example, 85% or more, and a high attenuation to visible light, for example, 70% or more, so that a user can hardly see the area of the electronic device 100 covered by the infrared transmissive ink 40 with naked eyes in normal use. Specifically, infrared-transmissive ink 40 may cover areas of inner surface 32 that do not correspond to display 90.

The ir-transparent ink 40 can also cover at least one of the chassis access through hole 23 and the chassis structured light through hole 24, i.e. the ir-transparent ink 40 can cover both the chassis access through hole 23 and the chassis structured light through hole 24 (as shown in fig. 5), so that it is difficult for a user to see the internal structure of the electronic device 100 through the chassis access through hole 23 and the chassis structured light through hole 24, and the electronic device 100 has a beautiful appearance; the IR transmissive ink 40 may also cover the chassis access opening 23 and uncover the chassis structured light opening 24; alternatively, the IR transmissive ink 40 may cover the chassis structure light through aperture 24 and uncover the chassis access through aperture 23.

Referring to FIG. 6, the optical sensor 52 is a single package structure. The light sensor 52 is installed in the installation groove 25 and located on the side of the back 93 of the display 90, in other words, the light sensor 52 is located below the display 90. The light sensor 52 corresponds to the light-transmissive solid region 91, and specifically, visible light outside the electronic device 100 can pass through the light-transmissive solid region 91 and be transmitted onto the light sensor 52. The light sensor 52 receives the visible light in the ambient light and detects the intensity of the visible light as a basis for controlling the display brightness of the display 90. In this embodiment, the light sensor 52 is first installed in the installation groove 25, and then the display 90 is installed on the housing 20, and the light sensor 52 may be in contact with or spaced apart from the display 90. In other embodiments, the light sensor 52 may be mounted on the display 90 such that the light sensor 52 corresponds to the transparent solid area 91, and then the display 90 and the light sensor 52 are mounted on the housing 20.

Referring to fig. 3 and 7, the proximity sensor 51 is a single package structure. The infrared light emitted from the proximity infrared lamp 13 is reflected by the external object and then received by the proximity sensor 51, and the proximity sensor 51 determines the distance between the external object and the electronic device 100 according to the received reflected infrared light.

Referring to fig. 1 and 7, the imaging module 60 may be one or both of a visible light camera 61 and an infrared camera 62. The imaging module 60 includes a lens mount 63, a lens barrel 64, and an image sensor 65. The lens barrel 64 is mounted on the lens holder 63, and the image sensor 65 is housed in the lens holder 63. The mirror base 63 includes a mounting surface 631, and the mounting surface 631 is located between the lens barrel 64 and the image sensor 65. In the embodiment shown in fig. 7, the proximity sensor 51 is disposed on the mounting surface 631, and specifically, the proximity sensor 51 at least partially falls on the mounting surface 631 in the orthographic projection of the plane where the mounting surface 631 is located, so that the proximity sensor 51 and the imaging module 60 are disposed compactly, and the lateral space occupied by the two together is small.

Referring to fig. 1, the receiver 70 is used for sending out an acoustic signal when being excited by a power supply, and a user can talk through the receiver 70. The infrared fill-in light 80 is used for emitting infrared light, and after the infrared light is reflected by the surface of an external object, the infrared camera 62 of the electronic device 100 receives the infrared light reflected by the object to obtain image information of the object.

In the embodiment shown in fig. 1, the imaging module 60 includes a visible light camera 61 and an infrared light camera 62, and the centers of the output module 10, the visible light camera 61, the infrared light camera 62, the receiver 70 and the infrared supplementary lighting lamp 80 are located on the same line segment. Specifically, the output module 10, the infrared fill light 80, the receiver 70, the infrared camera 62, and the visible light camera 61 (as shown in fig. 8) are sequentially arranged from one end to the other end of the line segment; or the output module 10, the visible light camera 61, the receiver 70, the infrared camera 62 and the infrared light supplement lamp 80 (as shown in fig. 1) are sequentially arranged from one end of the line segment to the other end; or the infrared camera 62, the infrared light supplement lamp 80, the receiver 70, the visible light camera 61 and the output module 10 are arranged in sequence from one end to the other end of the line segment; or the infrared camera 62, the visible light camera 61, the receiver 70, the output module 10 and the infrared light supplement lamp 80 are arranged from one end of the line segment to the other end of the line segment in sequence. Of course, the arrangement of the output module 10, the infrared camera, the receiver 70, the visible light camera 61, and the infrared fill-in lamp 80 is not limited to the above example, and may be other shapes, such as a circular arc shape with the center of each electronic component and a rectangular shape with the center.

Further, referring to fig. 7, the proximity sensor 51 may be disposed on the mounting surface 631 of the infrared camera 62, or may be disposed on the mounting surface 631 of the visible light camera 61, of course, the proximity sensor 51 may not be disposed on the mounting surface 631, and the proximity sensor 51 may be disposed adjacent to the output module 10 to easily receive the infrared light emitted by the proximity infrared lamp 13 and reflected by the external object; the proximity sensor 51 may also be located adjacent to the receiver 70, and when the user answers the call, the proximity sensor 51 easily detects that the user's ear is close to the receiver 70.

In summary, in the electronic device 100 according to the embodiment of the invention, the output module 10 integrates the structured light projector 12 and the proximity infrared lamp 13 into a single package structure, and integrates the functions of emitting infrared light for infrared distance measurement and stereo imaging, so that the integration level of the output module 10 is higher, the volume is smaller, and the output module 10 saves the space for realizing the functions of stereo imaging and infrared distance measurement. In addition, since the structured light projector 12 and the proximity infrared lamp 13 are carried on the same package substrate 111, compared with the structured light projector 12 and the proximity infrared lamp 13 in the conventional process, which need to be manufactured by different wafers and then assembled on a PCB substrate for packaging, the packaging efficiency is improved. Meanwhile, the light sensor 52 is disposed on the side of the back 93 of the display 90, so that the light sensor 52 does not occupy the space between the edge of the display 90 and the edge of the casing 20, and the gap between the edge of the display 90 and the edge of the casing 20 can be made smaller, that is, the display area of the display 90 can be increased to improve the screen occupation ratio of the electronic device 100.

Referring to fig. 3, in some embodiments, the output module 10 further includes a proximity lamp lens 19. The proximity lamp lens 19 is provided inside the package case 11 and corresponds to the proximity infrared lamp 13. The infrared light emitted from the proximity infrared lamp 13 is focused by the proximity lamp lens 19 into the proximity window 1132 and exits, reducing the amount of light emitted to other areas of the package sidewall 112 and package top 113.
