Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a sensor module and a mobile terminal.
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 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 infrared emitter is too close to the infrared receiver 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 diffraction in the intelligent terminal, so that a basic value detected by the infrared receiver is larger; and the light intensity detected by the infrared receiver changes little after the reflected light enters the infrared receiver due to the fact that the blocking object is far away from the infrared receiver. Therefore, the sensitivity of the infrared receiver is very low, and erroneous judgment 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 sensor module in the embodiment of the invention receives the first signal and the second signal respectively through the first signal receiver and the second signal receiver; when the blocking object is far away from the mobile terminal, the second signal receiver is far away from the signal transmitter, at the moment, fewer signals directly enter the second signal receiver by diffraction in the mobile terminal, and more reflected signals enter the second signal receiver, so that the intensity change of the signals detected by the second signal receiver is larger, and the sensitivity is higher; when the blocking object is closer to the mobile terminal, the first signal receiver is closer to the signal transmitter, and reflected signals enter the first signal receiver more, so that the intensity of the signals detected by the first signal receiver is larger in change, and the sensitivity is higher; therefore, whether the barrier is close to or far from the mobile terminal, the sensor module has higher sensitivity, so that the detection accuracy of the sensor module can be improved.

Referring to fig. 1, fig. 1 is a schematic diagram of a mobile terminal 1000 according to an embodiment of the invention. The mobile terminal 1000 is an electronic device such as a mobile phone or a tablet computer. It is understood that mobile terminal 1000 includes, but is not limited to, examples of this embodiment.
The mobile terminal 1000 includes a panel assembly 100 and a housing 200. The panel assembly 100 is disposed on and coupled to the housing 200. It will be appreciated that the mobile terminal 1000 may also include a receiver. Correspondingly, the non-display area 100a of the panel assembly 100 is provided with an opening 300 for a receiver to emit sound, and the mobile terminal 1000 may further include a fingerprint recognition module 400, where the fingerprint recognition module 400 is disposed in the non-display area 100a of the panel assembly 100. The display area 100b of the panel assembly 100 may be used to display a picture or for a user to touch and manipulate or the like.
The panel assembly 100 may be a touch panel assembly, a panel assembly, or a mobile terminal panel assembly having other functions, or the like.
Referring to fig. 2, fig. 2 is a schematic diagram of a first structure of a panel assembly 100 according to an embodiment of the invention. The panel assembly 100 includes a sensor module 11, a cover plate assembly 12, and a control circuit 13. The sensor module 11 is disposed on one side of the inner surface of the cover assembly 12, and the sensor module 11 is spaced from the cover assembly 12. The control circuit 13 is in communication with the sensor module 11 and the cover assembly 12. In this embodiment, the control circuit 13 is a motherboard, and the sensor module 11 is fixedly disposed on the motherboard.
The sensor module 11 includes a first signal transmitter 111, a first signal receiver 112, and a second signal receiver 113.
The signal transmitter 111 is used to transmit signals outwards. The signal receiver 112 and the signal receiver 113 are used to receive signals reflected by external objects.
The signal may be an optical signal such as infrared light or laser light, or an acoustic signal such as ultrasonic wave. The following will exemplify only the optical signal, the optical transmitter, and the optical receiver.
In some embodiments, the first light emitter 111 is configured to emit detection light, such as infrared light, having a wavelength greater than 850nm, which is an infrared emitter. For example, the first light emitter 111 may be an LED (Light Emitting Diode ) emitting infrared rays.
Correspondingly, the first light receiver 112 may be an infrared light receiver for receiving a low beam signal formed after the detection light is reflected by the barrier 70. The barrier 70 is typically a human face and is used in a scene when the mobile terminal is near or far from the face during a call.
Correspondingly, the second light receiver 113 may be an infrared light receiver, for receiving a far-reaching signal formed after the detection light is reflected by the barrier 70.
The low beam signal indicates that the light receiver reflected by the blocking object is closer to the first light emitter 111, and the high beam signal indicates that the light receiver reflected by the blocking object is farther from the first light emitter 111.
The distance between the first light receiver 112 and the first light emitter 111 is smaller than the distance between the second light receiver 113 and the first light emitter 111. Therefore, the second light receiver 113 is more sensitive to light intensity variation detection when the cover assembly 12 is farther from the barrier. The detection of the light intensity variation of the first light receiver 112 is more sensitive when the cover assembly 12 is closer to the barrier. Therefore, in a specific application, the mobile terminal can determine whether the mobile terminal is far away or near according to the light intensity values of the reflected light received by the first light receiver 112 and the second light receiver 113, so that the accuracy of the determination can be greatly improved, and the user experience can be improved.
In this embodiment, the first optical transmitter 111 and the first optical receiver 112 may be integrally disposed in a first integrated chip to form a two-in-one chip. Of course, it is also possible to provide two separate chips separately.
The cover assembly 12 includes a cover 121, a first adhesive layer 122 disposed on an inner surface of the cover 121, and a second adhesive layer 123 disposed on a surface of the first adhesive layer 122 away from the cover 121. The first adhesive layer 122 completely covers the second adhesive layer 123. Wherein the first adhesive layer 122 and the second adhesive layer 123 constitute an adhesive layer.
The first adhesive layer 122 and the second adhesive layer 123 are disposed to hide the internal structural components of the mobile terminal 1000 and the second adhesive layer 123. I.e. so that the user can see only the first adhesive layer 122 and not the second adhesive layer 123 when viewing on the outside of the cover plate 121.
Wherein the cover 121 may be a transparent glass cover. In some embodiments, the cover plate 121 may be a glass cover plate made of a material such as sapphire.
The adhesion layer may be an ink layer or a coating layer formed of other materials. The following will be exemplified by using the adhesive layer as an ink layer, the first adhesive layer as a light-transmitting ink layer, and the second adhesive layer as a light-shielding ink layer.
In this embodiment, the light-transmitting ink layer 122 is a light-transmitting ink layer for transmitting most of light. The transmittance of the ink layer may be set according to practical requirements, and the visible light (such as visible light with a wavelength of 550 nm) transmittance of the light-transmitting ink layer 122 is generally between 2% and 10%, and the light signal (such as infrared with a wavelength of 850 nm) transmittance of the proximity sensor is generally greater than or equal to 80%.
The clear ink layer 122 may include several clear ink sub-layers 1221. For example, in the present embodiment, the light-transmitting ink layer 122 has 3 light-transmitting ink sub-layers 1221, and each light-transmitting ink sub-layer 1221 is formed by spraying or printing white ink. Of course, white ink is only an example, and the light-transmitting ink layer 122 can be designed with other colors according to different aesthetic requirements.
The light-shielding ink layer 123 is an ink layer that can shield light, and is used for shielding most of light. The light shielding ink layer 123 may be formed by spraying or printing with black ink. The light shielding ink layer 123 includes a first region and a second region. The first region has a transmittance for light that is greater than a transmittance for light of the second region. The first region may be understood as a light-transmitting region for transmitting a substantial portion of the light. The second region may be understood as a light-shielding region for shielding a substantial part of the light.
Wherein the light-transmitting ink layer 122 covers the first region on the light-shielding ink layer 123.
Wherein, the transmittance of the light-transmitting ink layer 122 to light is greater than the transmittance of the light-shielding ink layer 123 to light.
The transmittance may include transmittance for infrared rays, transmittance for laser light, and transmittance for visible light.
In some embodiments, the light-shielding ink layer 123 is provided with a first light-passing hole 124 and a second light-passing hole 125. The first light-passing hole 124 and the second light-passing hole 125 are used for transmitting light. The first light-passing hole 124 and the second light-passing hole 125 form a first region, and the region of the light-shielding ink layer 123 outside the first light-passing hole 124 and the second light-passing hole 125 is a second region. It is understood that the first light-passing hole 124 and the second light-passing hole 125 may be filled with a light-transmitting material, and the color of the light-transmitting material may be the same as that of the light-transmitting ink layer 122. The first light passing hole 124 may include a first light emitting hole 1241 and a first light receiving hole 1242, which are separated. The first light emitter 111 is opposite to the first light emitting hole 1241, and emits the detection light outwards through the first light emitting hole 1241. The first light receiver 112 is opposite to the first light receiving hole 1242, and receives the reflected light of the detection light through the first light receiving hole 1242.
The second light-passing hole 125 is opposite to the second light receiver 113, and the second light receiver 113 receives the reflected light of the detection light through the second light-passing hole 125.
The shapes of the first light emitting holes 1241, the first light receiving holes 1242, and the second light passing holes 125 may be set according to actual requirements. For example, the shape may be circular, rectangular, rounded rectangle, or the like. In order to improve the capability of the first light receiver 112 and the second light receiver 113 to receive the light signal and improve the sensitivity of the sensor, the opening areas of the first light receiving hole 1242 and the second light transmitting hole 125 may be larger than the opening area of the first light emitting hole 1241.
It will be appreciated that in other embodiments, as shown in fig. 3, the first light-passing aperture 124 may also be a larger aperture that is used by both the first light emitter 111 and the first light receiver 112.
In the present embodiment, the control circuit 13 is communicatively connected to the first optical transmitter 111, the first optical receiver 112 and the second optical receiver 113, and the first optical transmitter 111, the first optical receiver 112 and the second optical receiver 113 are all fixedly disposed on the motherboard.
For example, when the panel assembly 100 is applied to a mobile phone, the first light receiver 112 is closer to the first light emitter 111 because the first light receiver 112 and the second light receiver 113 are at different distances from the first light emitter 111, and when the panel assembly 100 is closer to the blocking object, the second light receiver 113 receives less light because the second light receiver 113 is farther from the first light emitter 111, and the light intensity variation value varies little with distance. When the panel assembly 100 is far from the blocking object, the reflected light is weak, and the light emitted by the first light emitter 111 directly enters the first light receiver 112 by internal reflection, the base value of the light intensity value received by the first light receiver 112 is large, and the cover plate is far from the blocking object, and the light intensity value of the reflected light is small, so that the reflected light received by the first light receiver is not obvious for the detected light intensity change. The second light receiver 113 is farther from the first light receiver 111 than the first light receiver 112, so that the portion of the light emitted from the first light receiver 111 that enters the second light receiver 113 through internal reflection is smaller, the basic light intensity value is smaller, and the light intensity variation after the reflected light enters the second light receiver 113 is relatively larger.
During the call of the mobile terminal, the control circuit 13 controls the first light emitter 111 to emit the detection light, and determines whether the mobile terminal mounted with the panel assembly 100 is close to or far from the face according to the light intensity values of the reflection light received by the first light receiver 112 and the second light receiver 113. The cover plate assembly 12 is controlled to lighten when the face is away from the face, and the cover plate assembly 12 is controlled to quench when the face is close to the face.
When the light intensity value received by the first light receiver 113 reaches a first proximity threshold or the light intensity value received by the second light receiver 113 reaches a second proximity threshold, the mobile terminal is determined to be close to the face. When the light intensity value received by the first light receiver 113 reaches a first far-away threshold and the light intensity value received by the second light receiver 113 reaches a second far-away threshold, the mobile terminal is judged to be far away from the face.
Referring to fig. 4, fig. 4 is another structural schematic diagram of a panel assembly 100 in an embodiment of the present invention. The panel assembly 100 includes a sensor module 21, a cover plate assembly 22, and a control circuit 23. The sensor module 21 is disposed on one side of the inner surface of the cover assembly 22, and the sensor module 21 is spaced from the cover assembly 22. The control circuit 23 is in communication with the sensor module 21 and the cover assembly 22. In this embodiment, the control circuit 23 is a motherboard, and the sensor module 21 is fixedly disposed on the motherboard.
The sensor module 21 includes a first light emitter 211, a first light receiver 212, a second light receiver 213, a second light emitter 214, a first ambient brightness sensor 215, and a second ambient brightness sensor 216.
It will be appreciated that in some embodiments, the sensor module 21 may also include a circuit board. The first light emitter 211, the first light receiver 212, the second light receiver 213, the second light emitter 214, the first ambient brightness sensor 215, and the second ambient brightness sensor 216 may be disposed on the circuit board.
Wherein the first light emitter 211 and the second light emitter 214 are each adapted to emit invisible light, e.g. infrared light, having a wavelength of more than 850 nm.
The first light emitter 211 and the second light emitter 214 are both infrared light emitters. The first light receiver 212 and the second light receiver 213 may be infrared light receivers. The first light receiver 212 is used for receiving a low beam signal formed after the detection light is reflected by the blocking object. The second light receiver 214 is configured to receive a high beam signal formed after the detection light is reflected by the blocking object. The distance between the first light receiver 212 and the first light emitter 211 is smaller than the distance between the second light receiver 213 and the first light emitter 211. Wherein, the low beam signal indicates that the light receiver reflected by the blocking object is closer to the first light emitter 211, and the high beam signal indicates that the light receiver reflected by the blocking object is farther from the first light emitter 211.
The distance between the first light receiver 212 and the first light emitter 211 is smaller than the distance between the second light receiver 213 and the first light emitter 211. Therefore, when the first light emitter 211 is used as a detecting light emitter, and when the panel assembly 100 is far from the blocking object, the light intensity variation detection of the second light receiver is more sensitive; the first light receiver is more sensitive to light intensity variation detection when the panel assembly 100 is closer to the barrier. When the second light emitter 214 is used as a detecting light emitter, and when the panel assembly 100 is far from a blocking object, the light intensity variation detection of the second light receiver 214 is more sensitive; when the panel assembly 100 is closer to the barrier, the light intensity variation detection of the first light receiver 212 is more sensitive.
In this embodiment, the control circuit 23 may select one of the first light emitter 211 and the second light emitter 214 as the emitter of the detection light, and typically, the first light emitter 211 is used as the emitter of the detection light, and when the control circuit 23 detects that the first light emitter 211 is abnormal or damaged, the second light emitter 214 is used as the emitter of the detection light.
In some embodiments, the first light emitter 211, the first light receiver 212, and the first ambient brightness sensor 215 may be integrally disposed on an integrated chip to form a three-in-one chip. The second light emitter 214, the second light receiver 213, and the second ambient brightness sensor 216 may be integrally disposed on another integrated chip to form another three-in-one chip.
In some embodiments, as shown in fig. 5, the sensor module 21 may include only the light emitter 211, the first light receiver 212, the second light receiver 213, and the ambient brightness sensor 216. The light emitter 211, the first light receiver 212, the second light receiver 213, and the ambient brightness sensor 216 may be disposed on a circuit board.

The second light receiver 213 and the ambient brightness sensor 216 may be integrally disposed on another integrated chip to form another two-in-one chip. The two-in-one chips can be arranged on the circuit board at intervals.
The distance between the two-in-one chips is between 2 mm and 12 mm. The distance is the distance between the geometric centers of the two-in-one chips.
The cover plate assembly 22 includes a cover plate 221, a light-transmissive ink layer 222 disposed on an inner surface of the cover plate 221, and a light-blocking ink layer 223 disposed on a side of the light-transmissive ink layer 222 remote from the cover plate 221. Wherein the light-transmitting ink layer 122 and the light-shielding ink layer 123 constitute an ink layer.
The light-transmitting ink layer 222 may include a plurality of light-transmitting ink sub-layers 2221, for example, in the present embodiment, the light-transmitting ink layer 222 has three light-transmitting ink sub-layers 2221, and each light-transmitting ink sub-layer 2221 is formed by spraying or printing white ink. Of course, white ink is only an example, and the light-transmitting ink layer 222 can be designed with other colors according to different aesthetic requirements.
The light shielding ink layer 223 may be formed by spraying or printing with black ink. The light-shielding ink layer 223 is provided with a first light-passing hole 224 and a second light-passing hole 225.
The light-transmitting ink layer 222 that may be positioned on the light-shielding ink layer 223 in this embodiment is a light-transmitting ink layer. The transmittance of the ink layer may be set according to practical requirements, and the visible light (such as visible light with a wavelength of 550 nm) transmittance of the light-transmitting ink layer 222 is generally between 2% and 10%, and the light signal (such as infrared with a wavelength of 850 nm) transmittance of the proximity sensor is generally greater than or equal to 80%.
The first light passing hole 224 may include a first light emitting hole 2241 and a first light receiving hole 2242, which are separated. The first light emitter 211 is opposite to the first light emitting hole 2241, and emits the detection light outwards through the first light emitting hole 2241. The first light receiver 212 and the first ambient brightness sensor 215 are opposite to the first light receiving hole 2242, the first light receiver 212 receives the reflected light of the detection light through the first light receiving hole 2242, and the first ambient brightness sensor 215 detects the intensity of the ambient light through the first light receiving hole 2242.
The second light passing hole 225 may include a separate second light emitting hole 2251 and a second light receiving hole 2252. The second light emitter 214 is opposite to the second light emitting hole 2251, and emits detection light outwards through the second light emitting hole 2251. The second light receiving hole 2252 is opposite to the second light receiver 213 and the second ambient light sensor 216, the second light receiver 213 receives the reflected light of the detection light through the second light receiving hole 2252, and the second ambient light sensor 216 detects the intensity of the ambient light through the second light receiving hole 2252.
It will be appreciated that in other embodiments, as shown in fig. 6, the first light-passing aperture 224 may also be a larger aperture that is used by the first light emitter 211, the first light receiver 212, and the first ambient brightness sensor 215 simultaneously.
The second light passing hole 225 may also be a larger hole that is used by the second light emitter 214, the second light receiver 213, and the second ambient brightness sensor 216 simultaneously.
In describing the application of the panel assembly 100 to a mobile phone, the control circuit 23 normally selects the first light emitter 211 as the emitter of the detection light, and the second light emitter 214 does not operate.
In some embodiments, as shown in fig. 7, the cover plate assembly 22 may include only the cover plate 221 and the light-transmissive ink layer 222 disposed on the inner surface of the cover plate 221.
The light-transmitting ink layer 222 may be formed by spraying or printing a special ink. For example, the special ink may be an infrared ink (IR ink). The IR ink has a transmittance of 80% or more with respect to infrared rays, and thus can transmit most of infrared rays. The appearance of the IR ink appears as a black ink.
A functional area may be disposed on the light-transmitting ink layer 222 at a position corresponding to the ambient brightness sensor 216, and ink that is transparent to ambient light may be sprayed or printed on the functional area. The functional area is for passing ambient light such that the ambient brightness sensor 216 detects ambient brightness.
Referring back to fig. 6, the first light receiver 212 is closer to the first light emitter 211 due to the different distances of the first light receiver 212 and the second light receiver 213 from the first light emitter 211. As the panel assembly 100 is closer to the barrier 70, the second light receiver 213 receives little or no reflected light due to the greater distance from the first light emitter 211, and the light intensity variation value varies little with distance. When the panel assembly 100 is far from the barrier 70, the light emitted by the first light emitter 211 directly enters the first light receiver 212 by internal reflection, the base value of the light intensity value received by the first light receiver 212 is larger, and the light intensity value of the reflected light is smaller when the cover assembly 23 is far from the barrier 70, so that the change of the light intensity value detected by the reflected light received by the first light receiver 212 is smaller and less obvious; at this time, the second light receiver 113 is farther from the first light receiver 111 than the first light receiver 112, so that the portion of the light emitted from the first light receiver 211 that is internally reflected into the second light receiver 213 has smaller base light intensity value, and the reflected light after being reflected enters the second light receiver 213 has relatively larger light intensity variation.
During the call, the control circuit 23 controls the first light emitter 211 to emit detection light, and determines whether the mobile terminal mounted with the panel assembly 100 is close to or far from the face according to the light intensity values of the reflected light received by the first light receiver 212 and the second light receiver 213, and controls the cover assembly 22 to turn on when the mobile terminal is far from the face, and controls the cover assembly 22 to turn off when the mobile terminal is close to the face. When the light intensity value received by the first light receiver 213 reaches a first proximity threshold or the light intensity value received by the second light receiver 213 reaches a second proximity threshold, the mobile terminal is determined to be close to the face. When the light intensity value received by the first light receiver 213 reaches the first far-away threshold and the light intensity value received by the second light receiver 213 reaches the second far-away threshold, the mobile terminal is judged to be far away from the face.
