Background
With rapid development of terminal technology, intelligent terminals are becoming more and more popular and become indispensable equipment in life. People can learn, entertain and the like through the intelligent terminal.
In the prior art, a proximity sensing module of an intelligent terminal is usually implemented by using an infrared emitter and an infrared receiver. The infrared emitter emits infrared light, the infrared light is reflected by the barrier to form reflected light, and the infrared receiver receives the reflected light and judges whether the intelligent terminal is close to or far from the barrier according to the light intensity value of the reflected light.
However, in actual use, if the infrared emitter is too far from the infrared receiver, reflected light cannot enter the infrared receiver when the barrier is close. When the distance between the infrared emitter and the infrared emitter is too short and the intelligent terminal is too far away from the barrier, part of infrared rays emitted by the infrared emitter directly enter the infrared receiver through reflection inside the intelligent terminal, so that the detected basic value of the infrared receiver is larger; the blocking object is far away from the infrared receiver, so that the reflected light rays of the blocking object after entering the infrared receiver cause the light intensity detected by the infrared receiver to change very little, and therefore, the sensitivity of the infrared receiver is very low, and misjudgment or missed judgment is easy to occur.
From the above, the detection sensitivity of the proximity sensor assembly of the conventional mobile terminal is low, and a judgment error or a judgment failure is likely to occur.

The first signal transmitter 311, the second signal transmitter 312, and the first signal receiver 313 are electrically connected to the circuit board structure 314. The distance between the first signal transmitter 311 and the first signal receiver 313 is smaller than the distance between the second signal transmitter 312 and the first signal receiver 313. It is understood that circuit board structure 314 may not be a component of sensor assembly 31, but rather may be a side-by-side structure with sensor assembly 31.
Wherein, the first signal emitter 311 is configured to emit invisible light with a wavelength greater than 850nm as a first signal, such as infrared light. The first signal transmitter 311 may be an infrared transmitter. The first signal emitted by the first signal emitter 311 is reflected by the barrier 70 to form a first reflected signal.
The second signal emitter 312 is configured to emit invisible light having a wavelength greater than 850nm as a second signal, such as infrared light. The second signal transmitter 312 may be an infrared transmitter. The second signal from the second signal transmitter 312 is reflected by the barrier 70 to form a second reflected signal
The first signal receiver 313 is configured to receive the first reflected signal and the second reflected signal, and convert the first reflected signal and the second reflected signal into electrical signals for analysis by the circuit board structure 314 to determine whether the mobile terminal 1 is approaching or moving away from the barrier 70.
The first ambient light sensor 315 is configured to detect the brightness of ambient light, and the mobile terminal 1 performs adaptive control or adjustment according to the brightness value, for example, adjusts the display brightness of the panel 20 according to the ambient brightness.
In some embodiments, the first signal transmitter 311 is disposed proximate to the first signal receiver 313, and the second signal transmitter 312 is disposed remote from the first signal receiver 313, for example, the first signal transmitter 311 and the first signal receiver 313 may be integrally packaged to form a first package a. The first package is spaced apart from the second signal emitter 312. The first ambient light sensor 315 and the second signal emitter 312 may be packaged together to form a second package B. Wherein the distance between the first package a and the second signal emitter 312 is between 2 mm and 12 mm, and the distance refers to the distance between the first package a and the center of the collection of the second signal emitters 312.
It will be appreciated that the first ambient light sensor 315 may also be packaged within the first package a together with the first signal transmitter 311 and the first signal receiver 313, as shown for example in fig. 3.
With continued reference to fig. 2, the cover plate 32 includes a cover plate body 321, a first adhesion layer 322 and a second adhesion layer 323. The non-display area 30a of the cover 32 covers the non-display portion of the panel 20, and the display area 30b of the cover 32 covers the display portion of the panel 20. The cover body 321 has an inner surface and an outer surface, the first adhesive layer 322 is disposed on the surface of the cover body 321 facing the sensor assembly 31 and located on the non-display area 30a, that is, the inner surface of the cover body 321, and the second adhesive layer 323 is disposed on the first adhesive layer 322.
The cover body 321 is made of a transparent material, for example, the cover body 321 is a glass cover. The cover body 321 may also be a glass cover made of a material such as sapphire. The first adhesive layer 322 completely covers the second adhesive layer 323. The first adhesive layer 322 and the second adhesive layer 323 are disposed to hide the internal structural members of the mobile terminal 1 and the second adhesive layer 323. That is, the user can see only the first adhesive layer 322 and not the second adhesive layer 323 when viewing the outside of the cover plate body 321.
The transmittance of the first adhesive layer 322 is greater than the transmittance of the second adhesive layer 323.
For example, the transmittance of the first adhesive layer 322 may be 80% or more, and the transmittance of the second adhesive layer 323 may be 10% or less. In practice, the first attachment layer 322 may be referred to as a transmissive layer for transmitting a substantial portion of the signal. The second adhesion layer 323 may be referred to as a shielding layer for shielding most of the signal.
In practical applications, the second adhesion layer 323 is used for hiding the internal structure of the mobile terminal 1, so that the internal structure of the mobile terminal 1 cannot be seen from the outer side of the cover plate body 321, thereby realizing the overall aesthetic effect of the mobile terminal 1.
Wherein the first adhesion layer 322 may be a white ink layer and the second adhesion layer 323 may be a black ink layer. Of course, the white ink layer and the black ink layer are only examples, and the first attaching layer 322 and the second attaching layer 323 can be designed with other colors according to different aesthetic requirements, as long as the transmittance of the first attaching layer 322 is greater than the transmittance of the second attaching layer 323. Wherein the white ink layer, the black ink layer or the ink layers of other colors can be manufactured by spraying or printing process. The first adhesive layer 322 may be an ink layer with blue, gold, red, pink, etc.
The first adhesive layer 322 is a plurality of layers, and the second adhesive layer 323 is a single layer or a plurality of layers. For example, the first attachment layer 322 includes three sublayers 3221, the three sublayers 3221 overlapping in sequence.
Alternatively, for example, as shown in fig. 4, the first adhesive layer 322 may be a single layer and the second adhesive layer 323 may be a single layer.
With continued reference to fig. 2, the second adhesive layer 323 and the first adhesive layer 321 together define a functional area, so that the functional area is hidden on the appearance surface of the cover body 321. The functional area may be an image acquisition aperture, a receiver aperture, a proximity sensor aperture, or an iris recognition aperture that supplies the camera element. Alternatively, in the present embodiment, the second adhesion layer 323 may include a first region 323A and a second region 323B, and the first region 323A is also the functional region. The first region 323A may be understood as a portion where the second adhesive layer 323 and the first adhesive layer 322 overlap each other, and the second region 323B may be understood as a portion where the second adhesive layer 323 and the first adhesive layer 321 do not overlap each other. The transmittance of the first region 323A is greater than the transmittance of the second region 323B, so that the signal can sequentially pass through the first region 323A, the first adhesive layer 322, the cover body 321, and the first region 323A after being reflected by the external barrier 70.
Wherein the first adhesive layer 32 covers the first area 323A of the second adhesive layer 323 such that the first area 323A is not visible from outside the mobile terminal 1.
In some embodiments, when the second adhesion layer 323 is a black ink layer, the black ink of the first region 323A may be treated so that the transmittance of the region is greater than that of the second region 323B.
In some embodiments, the first region 323A may be provided as a through hole, where the transmittance of the region is 100%, and the first adhesive layer 322 covers the through hole. In some embodiments, the via holes of the first region 323A may be filled with a material that is permeable to signals.
In some embodiments, the first region 323A includes a first sub-region 3231A and a second sub-region 3232A. The first sub-region 3231A is opposite the first signal transmitter 311 and the first signal receiver 313, and the second sub-region 3232A is opposite the second signal transmitter 312 and the first ambient light sensor 315. The first sub-region 3231A and the second sub-region 3232A are through holes defined by the boundary of the second region 323B.
Referring to fig. 5, the embodiment of the present invention also provides a terminal control method, which is implemented by using the mobile terminal in the above embodiment, and the method includes the following steps:
s101, circuit board structure 314 controls the first signal emitter 311 to emit a first signal, and the first signal is reflected by the barrier 70 to form a first reflected signal.
S102, circuit board structure 314 controls second signal emitter 312 to emit a second signal that is reflected by barrier 70 to form a second reflected signal.
S103, circuit board structure 314 acquires a photoelectric conversion value generated by first signal receiver 313 according to the detected first signal and second signal.
S104, the circuit board structure 314 judges the approaching state of the mobile terminal 1 and the barrier 70 according to the photoelectric conversion value, and responds according to the judging result.
In the step S104, the photoelectric conversion value is a result of the first reflected signal and the second reflected signal acting together on the first signal receiver 313. When the photoelectric conversion value is located in the first interval, judging that the mobile terminal 1 is close to the barrier 70; when the photoelectric conversion value is located in the second interval, the mobile terminal is determined to be far away from the barrier 70. The first section and the second section are empirical values obtained by detecting a plurality of times in advance.
In practical applications, the step S104 may further include: circuit board structure 314 obtains in advance a base value corresponding to the intensity of light entering the first light receiver after the signals emitted by the first light emitter and the second light emitter are diffracted in the first adhesion layer. Circuit board structure 314 then determines the proximity of terminal 1 to barrier 70 based on the base value and the photoelectric conversion value. In practice, the circuit board structure 314 subtracts the base value from the photoelectric conversion value to obtain an actual conversion value corresponding to reflection, and determines the approaching state of the mobile terminal 1 and the barrier 70 according to the actual conversion value. When the actual conversion value is located in the third interval, determining that the mobile terminal 1 is close to the barrier 70; when the actual conversion value is in the fourth interval, it is determined that the mobile terminal is far away from the barrier 70. The third section and the fourth section are empirical values obtained by detecting a plurality of times in advance.
According to the embodiment of the invention, the first signal emitter and the second signal emitter are arranged to emit the detection signals, and the first reflection signals and the second reflection signals formed by the detection signals reflected by the barrier are received through the first signal receiver, so that the condition that the reflection signals cannot be detected under the condition that the detection signals are close to or far from the barrier is avoided, and the detection sensitivity of the sensor assembly can be improved.

The distance between the second signal receiver 316 and the second signal transmitter 312 is smaller than the distance between the second signal receiver 316 and the first optical signal transmitter 311.
