The housing 20 has a receiving cavity 22, and the receiving cavity 22 is used for receiving the light guide 30.
The light guide 30 is disposed in the accommodating cavity 22 and is used for transmitting light outside the display screen 10 to the sensor assembly 40, or transmitting light emitted by the sensor assembly 40 to the outside of the display screen 10 through the light guide 30. Alternatively, the light guide 30 is made of a material having light guiding or total reflection, such as polymethyl methacrylate or polycarbonate material, which is not particularly limited.

Specifically, in an embodiment, the electronic device 100 includes a sound emitting portion 90, and the sound emitting portion 90 is used for transmitting sound emitted from the inside of the electronic device 100 to the outside of the electronic device 100. The light inlet 32 of the light guide 30 is disposed adjacent to the sound outlet 90 of the electronic device 100, in this embodiment, the sound outlet 90 is formed in two parts, one part includes a plurality of sound outlet holes, the other part includes only one sound outlet hole, the light guide 30 is located on one side with a smaller number of sound outlet holes, so that the light guide 30, the sound outlet 90 and the camera assembly 60 are integrated more highly, and the space is saved, thereby providing possibility for further increasing the screen occupation ratio. In another embodiment, the entire sound emitting portion 90 may also include only one sound emitting hole, which is not limited to this, as shown in fig. 6, and fig. 6 is a schematic partial enlarged structure view of an electronic device in another embodiment of the present disclosure.
With continued reference to fig. 5, optionally, in an embodiment, an end surface of the light guide 30 near the glass cover plate 11 is coated with an ink layer 50, or a position of the glass cover plate 11 facing the light guide 30 is coated with the ink layer 50. It is understood that in the embodiment of coating the ink layer 50 on the glass cover plate 11, the ink layer 50 is located on the inner side of the glass cover plate 11, that is, the side of the glass cover plate 11 close to the light guide member 30. Specifically, in various embodiments, the transmittance of the ink layer 50 is in a range of 12% to 18%. With such a structure and the light-transmitting range of the ink layer 50, the user cannot see the arrangement of the light-transmitting hole from the outside of the glass cover plate 11, so that the whole display screen of the electronic device 100 can be better seen.
It can be understood that in the embodiment where the glass cover plate 11 is close to the light guide member 30 or the ink layer 50 is coated on the light guide member 30, the brightness of the light emitted from the glass cover plate 11 is lost or attenuated. The present application compensates the portion of the loss in light brightness received by the sensor assembly 40 due to the light brightness passing through the ink layer 50 back through a software algorithm.
The sensor assembly 40 is fixed inside the electronic device 100, and is abutted or disposed adjacent to one end of the light guide member 30 far away from the display screen 10, so that light rays outside the display screen 10 can be transmitted to the sensor assembly 40 by at least one total reflection in the light guide member 30. Specifically, the sensor assembly 40 may only include the light sensing element or the proximity device, or may include a two-in-one or three-in-one integrated assembly including the proximity device and the light sensing element, which is not limited in particular.
In an embodiment, when the sensor assembly 40 includes a proximity device, the following explains the operation principle of the electronic device 100 using the above technical solution. The functions realized by the scheme at least comprise: in the using process of the electronic device 100, the screen and the using situation of the user are matched, so that the user can turn off the screen when answering a call, the light emitted by the sensor assembly 40 is emitted onto the light guide member 30 after the screen is turned off, the light is transmitted by the light guide member 30 and finally emitted out of the display screen 10, and whether the electronic device is in a non-answering call state or not and whether the screen needs to be lightened or not are judged according to the received reflected light. It can be understood that the light emitted by the sensor assembly in this embodiment is an infrared light, and the infrared light is invisible light and cannot be detected by the user, and other light may be used in other embodiments, which is not limited in this respect.
Specifically, when the user uses the electronic device 100 to place the electronic device 100 at the ear for a call, the screen of the electronic device 100 is close to or contacts the ear or the face, so that the capacitance value in the display screen 20 changes, and when the capacitance value is within the preset range, it indicates that the user is using the electronic device 100 for a call to perform a screen-off operation. It can be understood that when the electronic device 100 is close to the ear and the face, the area of the whole screen close to the face or the ear is relatively large, and when the user is listening to a phone call with an earphone or hands-free, if the user only uses a finger to approach or touch the screen to perform other operations besides a call, since the area of the finger approaching or touching the screen is significantly smaller than the area of the face or the ear approaching or touching the display screen when the user holds the electronic device 100 to talk at the ear, the capacitance value in the display screen is in different ranges in the above two cases. Therefore, the screen can be actively turned off only when the user answers the phone by holding the electronic device 100, and the screen can not be turned off when the user touches the screen to perform other operations in other states, such as answering the phone as described above.
And after the screen of putting out appears in the display screen, sensor module 40 can constantly send light under the time interval that predetermines, this light is infrared light, infrared light passes leaded light spare 30 and glass apron 11 in proper order, when the user is using electronic device 100 to carry out the conversation, infrared light that sensor module 40 sent is beaten on user's ear, perhaps face, perhaps on the head, then infrared light reflection loops through glass apron 11 again, leaded light spare 60 beats on sensor module 40, sensor module 40 judges whether present user handheld electronic device 100 carries out the conversation in the ear according to the SNR of the infrared light that receives. Because the display screen is in close proximity to the user's face or ear while the user is holding the electronic device 100 in the ear, the signal-to-noise ratio of the infrared light reflected back is different from the signal-to-noise ratio of the infrared light received when the electronic device 100 has moved away from the user's ear or face. Therefore, on the premise of implementing the screen-off according to the change of the capacitance value of the display screen, the operation of turning on the screen is performed by continuously emitting infrared rays and judging whether the electronic device 100 has left the ear or the face of the user according to the signal-to-noise ratio formed by the infrared rays received after the emission.
In the embodiment where the sensor assembly 40 includes the light sensing element, the light sensing element receives the ambient light brightness outside the glass cover 11, so that the display screen can adjust the brightness of the display screen according to the ambient light brightness sensed by the light sensing element. When the user uses the electronic device 100, the situation that the display screen is dark, the user cannot see the picture on the display screen clearly, or the user needs to feel hard to see the picture on the display screen clearly under the condition that the ambient light is bright is avoided; and the condition that the display screen is abnormally bright to make a user feel dazzling when the ambient light is dark is avoided.
With continued reference to FIG. 4, in a further embodiment, the electronic device 100 further includes a camera assembly 60, the sensor assembly 40 is disposed adjacent to the camera assembly 60, and a projection of at least a portion of the light-incoming portion 32 and the transmitting portion 34 of the light-guiding member 30 in a direction perpendicular to the display screen 10 coincides with the camera assembly 60.

The lens assembly 66 has a smallest cross-sectional width in a direction parallel to the display screen 10 compared to the base 62 and base 64. With such a structure, the light guide member 30 is long, the light inlet portion 32 is arranged side by side with the lens assembly 66, the transmission portion 34 is curved along the shape of the base portion 64 and extends to be close to the sensor assembly 40, and the light inlet portion 32 directly abuts against the sensor assembly 40 or is arranged opposite to the sensor assembly 40.

In various embodiments, the light rays may be reflected within the light guide 30 two or more times. It can be understood that the total reflection of the brightness of the light in the light guide 30 may cause a certain degree of attenuation or loss to the brightness of the light, and in order to avoid the brightness distortion of the light, the present application compensates the part of the brightness loss of the light received by the sensor assembly 40 due to the total reflection of the light in the light guide 30 for a large number of times through a software algorithm.
Further, in another embodiment, the sensor assembly 40 includes at least one of a light receiving portion 42 or a light emitting portion (not shown), and the light receiving portion 42 or the light emitting portion is disposed near one side of the camera assembly 60, that is, the light receiving portion 42 or the light emitting portion is disposed toward the camera assembly 60 relative to the center of the sensor assembly 40, so that the light receiving portion 42 or the light emitting portion is disposed opposite to the light emitting portion 36 of the light guide 30.
