When the infrared lamp 12 is turned on and used as a proximity infrared lamp to emit infrared light to the outside of the package housing 11, infrared light passes through the light emitting window 1131 and reaches the surface of the object, and the proximity sensor 50 (shown in fig. 8) of the electronic device 100 receives the infrared light reflected by the object to detect the distance from the object to the electronic device 100 (at this time, the infrared lamp 12 is used for infrared ranging).

The infrared lamp 12 can emit infrared light to the outside of the package case 11 at different powers when used as an infrared fill light and when used as a near infrared lamp. Specifically, the infrared lamp 12 emits infrared light to the outside of the package housing 11 at a first power when serving as a proximity infrared lamp, and the infrared lamp 12 emits infrared light to the outside of the package housing 11 at a second power when serving as an infrared fill light, where the first power may be smaller than the second power.

Referring to fig. 1 and 8, the housing 20 may serve as a mounting carrier for the input/output module 10, or the input/output module 10 may be disposed in the housing 20. The housing 20 may be a housing of the electronic device 100, in the embodiment of the present invention, the housing 20 may further be used to set the display screen 90 of the electronic device 100, and since the volume occupied by the input/output module 10 according to the embodiment of the present invention is smaller, the volume occupied by the housing 20 to set the display screen 90 may be correspondingly increased, so as to increase the screen occupation ratio of the electronic device 100. Specifically, the housing 20 includes a top 21 and a bottom 22, the display 90 and the input/output module 10 are disposed between the top 21 and the bottom 22, and the top 21 is located above the bottom 22 in a state that the user normally uses the electronic device 100, as shown in fig. 1, the input/output module 10 may be disposed between the display 90 and the top 21.

When the input/output module 10 is disposed in the housing 20, the infrared lamp 12 corresponds to the housing light source through hole 23, and the optical sensor 1a corresponds to the housing light sensor through hole 24. The correspondence between the infrared lamp 12 and the casing light source through hole 23 means that light emitted by the infrared lamp 12 can pass through the casing light source through hole 23, specifically, the infrared lamp 12 is opposite to the casing light source through hole 23, or the light emitted by the infrared lamp 12 passes through the casing light source through hole 23 after being acted by the light guide element 13. The light sensor 1a and the case light sensing through hole 24 correspond to each other, and the visible light can pass through the case light sensing through hole 24 and be incident on the light sensor 1a, specifically, the light sensor 1a and the case light sensing through hole 24 are opposite, or the incident light of the visible light passes through the case light sensing through hole 24 and is incident on the light sensor 1a after being acted by the light guide element. The case light through hole 23 and the case light through hole 24 may be spaced apart from each other, but in other embodiments, the case light through hole 23 and the case light through hole 24 may be connected to 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 by the input/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. 8, the cover plate 30 covers the chassis light source through hole 23 and the chassis light sensing through hole 24, 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 an 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 infrared transmissive ink 40 can also block the chassis light source through hole 23 (as shown in fig. 8), so that it is difficult for a user to see the internal structure of the electronic device 100 through the chassis light source through hole 23, and the electronic device 100 has a beautiful appearance.

Referring to fig. 9, the proximity sensor 50 is a single package. The infrared lamp 12 emits infrared light when approaching the infrared lamp, and after the infrared light is reflected by an external object, the infrared light is received by the proximity sensor 50, and the proximity sensor 50 determines the distance between the external object and the electronic device 100 according to the received infrared light reflected by the object.

Referring to fig. 1 and 9, the imaging module 60 may be one or both of a visible light camera 61 and an infrared camera 62.
