The panel assembly 100 of the embodiment of the invention can be applied to a mobile terminal 1000, and 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.
In practical applications, the proximity sensor can determine whether the mobile terminal 1000 is close to the face by monitoring infrared light emitted by the signal emitter 21 (such as IR LED) when the mobile terminal 1000 is in communication, and can turn off the backlight of the screen when the mobile terminal 1000 is close to the face, thereby playing a role in saving electricity and preventing malfunction.
The panel 10 may be a touch panel, a display panel, a touch display panel, or a mobile terminal panel having other functions, or the like. Specifically, the panel 10 includes: cover plate 11, first adhesion layer group 17 and second adhesion layer 18 that set up in cover plate one side. It will be appreciated that the cover plate 11 is the exterior surface of the panel assembly 100, facing the user. A user may perform a gesture operation, such as clicking or sliding, on the surface of cover 11 to control mobile terminal 1000 to perform a corresponding function.
Further, the cover plate 11 includes a display area 14 and a non-display area 15; generally, the middle area of the cover plate 11 serves as a display area 14, and a non-display area 15 is provided around the display area 14. For example, the non-display area 15 is disposed on the top side or the bottom side of the display area 14. Referring to fig. 1, the top non-display area 15 of the cover plate 11 is further provided with a front camera hole 16 and a receiver through hole 13, wherein the receiver through hole 13 penetrates through the cover plate, the first adhesion layer and the second adhesion layer, and the receiver through hole is used for a receiver to transmit sound. In some embodiments, the front camera aperture 16 may be omitted, or eliminated.
For example, holes are sequentially formed in the non-display region 15, the first adhesive layer group 17, and the second adhesive layer 18 to obtain the receiver through hole 13.
As shown in fig. 2, the panel further includes a dust cover 12 for dust prevention and for covering the internal structure of the mobile terminal 1000 to achieve the effect of beautifying the mobile terminal 1000; the dust cover 12 is embedded in the receiver through hole.
Since the panel 10 is made of a light-transmitting material, a user can view contents displayed on the screen of the mobile terminal 1000 through the display area 14.
To make the mobile terminal 1000 more aesthetically pleasing, ink may be sprayed under the non-display area 15. The ink not only can meet the requirements of users on the mobile terminal 1000 with different colors, but also can cover the internal structure of the mobile terminal 1000 so as to achieve the effect of beautifying the mobile terminal 1000.
In this embodiment, a first adhesive layer group 17 is disposed below the non-display area 15, and the first adhesive layer group 17 includes at least one first adhesive layer 170; a second adhesive layer 18 is provided below the first adhesive layer group 17, as shown in fig. 11. It is understood that the number of the first adhesive layers 170 included in the first adhesive layer group 17 may be set according to practical requirements, such as 2 layers, 3 layers, 4 layers, etc. The present embodiment describes the panel 10 of the present invention by taking the example that the first adhesive layer group 17 includes three first adhesive layers 170, as shown in fig. 3.
Wherein the transmittance of the first adhesion layer is greater than the transmittance of the second adhesion layer. For example, the first adhesive layer may be a light-transmitting ink layer and the second adhesive layer may be a light-shielding ink layer.
The first and second attachment layers 170, 18 may be formed using a spray process, such as an electrostatic spray, a powder spray process, or the like. The first adhesive layer 170 may be a flat or complete first adhesive layer, i.e., the surface of the first adhesive layer 170 is uniformly sprayed with the light-transmitting ink, so that a whole surface of the first adhesive layer 170 has the light-transmitting ink.
The second adhesive layer 18 can block external ambient light or light inside the mobile terminal 1000 to cover structures inside the mobile terminal 1000. The ink color of the second adhesive layer 18 may be black, gray, etc., and may be set according to practical requirements.
The first adhesive layer group 17 can protect the second adhesive layer 18 from damage, and can also meet the user's demands for different color terminals 1000. For example, the ink color of the first adhesive layer 170 may be white, blue, etc., and may be set according to actual requirements.
In order to meet the requirement of receiving and transmitting optical signals of the proximity sensor, the second adhesion layer 18 is provided with a first light-transmitting area 181 and a second light-transmitting area 182, and the first adhesion layer covers the first light-transmitting area and the second light-transmitting area, so that the first light-transmitting area and the second light-transmitting area are hidden from view on the appearance of the cover plate, detection light emitted from the first light-transmitting area is emitted through the receiver through hole, and reflection light formed after being reflected by an external object enters the second light-transmitting area through the receiver through hole. The first light-transmitting area 181 is used for the proximity sensor to transmit light signals, and the second light-transmitting area 182 is used for the proximity sensor to receive light signals; wherein, the first light transmission area 181 and the second light transmission area 182 are both open to the receiver through hole 13.
In the embodiment of the invention, in order that the optical signal emitted by the proximity sensor is not emitted to the inside of the mobile terminal, the proximity sensor does not receive the optical signal diffracted from the inside. Therefore, by adding a reflective spacer in the channel for transmitting the optical signal from the proximity sensor, the optical signal is refracted inside the reflective spacer to the outside or enters the signal receiver 22. The implementation is as follows:
a first reflective spacer 183 is disposed on the inner side wall of the first light-transmitting region 181, and a second reflective spacer 184 is disposed on the inner side wall of the second light-transmitting region 182.
Wherein the signal emitter 21 is located below the first light-transmitting region 181, for emitting an optical signal to the outside through the first light-transmitting region; the signal receiver 22 is located below the second light-transmitting region 182, and is configured to receive the optical signal emitted by the signal emitter through the second light-transmitting region. The receiver 30 is located below the receiver through hole.
Wherein the first reflective spacer 183 extends downward from the first light transmissive region to the signal emitter location; the second reflective separator 184 extends downwardly from the second light transmissive region to the signal receiver location.
As shown in fig. 3 and 4, as an embodiment of the present invention, the first light-transmitting area 181, the second light-transmitting area 182, and the receiver through hole 13 are disposed at intervals. Thus, the signal transmitter 21, the signal receiver 22, and the receiver 30 are located on the same plane and are spaced apart. That is, the signal emitter 21 is located below the first light-transmitting region 181, for emitting an optical signal to the outside through the first light-transmitting region; the signal receiver 22 is located below the second light-transmitting region 182, and is configured to receive the optical signal emitted by the signal emitter through the second light-transmitting region. The receiver 30 is located below the receiver through hole.
As shown in fig. 5 and 6, as another embodiment of the present invention, in the case where the first light-transmitting region 181 and the second light-transmitting region 182 are both located in the receiver through-hole 13, then the proximity sensor is located above the receiver. That is, the first light-transmitting region, the second light-transmitting region and the receiver through-hole are integrally formed through-holes, so that the signal transmitter 21 is disposed above the receiver 30, then the first light-reflecting partition 183 having a cylindrical sleeve shape is sleeved above the signal transmitter 21, the signal receiver 22 is disposed above the receiver 30, and then the second light-reflecting partition 184 having a cylindrical sleeve shape is sleeved above the signal receiver 22, thereby refracting the optical signal inside the light-reflecting partition and transmitting it to the outside through the receiver through-hole 13 or into the signal receiver 22.
However, it is understood that the shape of the first and second reflective spacers 183 and 184 is not limited to a cylindrical shape, and may be other shapes.
It is understood that the shapes of the first light transmitting region 181 and the second light transmitting region 182 may be set according to actual requirements. For example, it may be formed in a circular shape, a rectangular shape, a rounded rectangular shape, or the like. The sizes of the first light-transmitting area 181 and the second light-transmitting area 182 may also be set according to practical needs, for example, when the holes may be circular holes, the aperture may be between 1.1mm and 1.3mm, or between 2mm and 3 mm. In order to improve the capability of the signal receiver 22 to receive the optical signal and improve the sensitivity of the sensor, the area of the second light-transmitting region 182 may be larger than that of the first light-transmitting region 181.
In addition, since the signal transmitter 21 and the signal receiver 22 transmit the optical signal through the receiver through hole and receive the reflected optical signal, the dust cover 12 can cover the internal structure of the mobile terminal 1000 to beautify the mobile terminal 1000. Thus, there is no limitation on the appearance opening of the mobile terminal 1000, so that the sizes and shapes of the first light-transmitting area 181 and the second light-transmitting area 182 are not limited, and the opening can be made according to the actual light receiving and emitting requirements of the sensing device (generally, the larger the hole is, the better the larger the hole is), so that the flexibility of opening and the performance of the proximity sensor are improved.
As shown in fig. 7 and 8, the proximity sensing process is as follows: the signal transmitter 21 generates an optical signal, and the optical signal is transmitted to the outside through the first light-transmitting area 181 and the receiver through hole 13, is reflected to the panel 10 after hitting the shielding object 70, and is reflected to the shielding object 70 by the panel 10, so that the optical signal is received by the signal receiver 22 through the receiver through hole 13 and the second light-transmitting area 182 after being reflected by the shielding object 70 and the panel 10.
In order to improve the sensing accuracy and performance of the proximity sensor, the present embodiment may further extend the distance between the signal transmitter 21 and the signal receiver 22. Preferably, the distance between the signal emitter 21 and the signal receiver 22 may be between 6 mm and 14 mm, and the distance between the signal emitter 21 and the signal receiver 22 may be a center-to-center distance (i.e., center distance), i.e., a distance between the center of the signal emitter 21 and the center of the signal receiver 22. Accordingly, the distance between the first light transmitting region 181 and the second light transmitting region 182 may be between 6 mm and 14 mm, and the distance between the first light transmitting region 181 and the second light transmitting region 182 may be a center distance, i.e., a distance between the center of the first light transmitting region 181 and the center of the second light transmitting region 182.
Preferably, the distance between the signal transmitter 21 and the signal receiver 22 may be between 10 mm and 12 mm. Such as a center-to-center distance between the signal transmitter 21 and the signal receiver 22 of between 10 mm and 12 mm.
Accordingly, the distance between the first light transmitting region 181 and the second light transmitting region 182 may be between 10 mm and 12 mm. For example, the center-to-center distance between the first light-transmitting region 181 and the second light-transmitting region 182 is between 10 mm and 12 mm.
In order to better realize proximity sensing, further improve sensing accuracy and performance of the proximity sensor, the embodiment may further increase the range corresponding to the signal receiver 22, that is, the range of proximity values that can be realized by the signal receiver 22, on the basis of increasing the distance between the signal transmitter 21 and the signal receiver 22.
For ease of assembly, the sensor assembly may be manufactured separately and then assembled with the panel. Therefore, the embodiment of the invention also provides a sensor assembly, which comprises a proximity sensor and a receiver; the proximity sensor includes a signal transmitter and a signal receiver; the signal transmitter is used for transmitting optical signals to the outside; the signal receiver is used for receiving the optical signal transmitted by the signal transmitter; wherein, a first reflective isolation plate is arranged above the periphery of the signal emitter; a second reflective isolation plate is arranged above the periphery of the signal receiver; the first reflective isolation plate is used for reflecting the optical signals emitted by the signal emitter to the outside, and the second reflective isolation plate is used for reflecting the optical signals emitted by the signal emitter back to the signal receiver for receiving.
As shown in fig. 9, as an embodiment of the present invention, the signal transmitter 21, the signal receiver 22, and the receiver 30 are located on the same plane and are spaced apart.
As another embodiment of the present invention, as shown in fig. 10, the proximity sensor is located above the receiver. I.e. the signal transmitter 21 and the signal receiver 22 are both located above the receiver 30, the signal transmitter 21 and the signal receiver 22 being located in the same plane and spaced apart.
In this way, the signal transmitter with the first reflective spacer and the signal receiver with the second reflective spacer can be assembled with the panel.
The embodiment of the invention also provides a mobile terminal, which comprises a shell, a panel and a printed circuit board, wherein the shell and the panel enclose a space, and the printed circuit board is positioned in the space; wherein the panel is the panel described above.

In summary, the panel assembly, the sensor assembly and the mobile terminal provided by the embodiment of the invention can simplify the manufacturing process of the mobile terminal because the proximity sensor is provided with the through hole of the receiver to transmit and receive the optical signal. In addition, as the light reflecting isolation plate is additionally arranged in the channel for transmitting the light signal by the proximity sensor, the light signal emitted by the proximity sensor is refracted to the outside in the light reflecting isolation plate and cannot be emitted to the inside of the mobile terminal, and the proximity sensor does not receive the light signal diffracted in the inside. Therefore, the detection sensitivity of the proximity sensor is improved, and the situation of judgment errors or judgment failures is effectively avoided.
