In the prior art, the proximity sensor of a mobile terminal is typically implemented using an infrared transmitter 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 mobile terminal is close to or far from the barrier according to the light intensity value of the reflected light.

Specifically, the panel 10 includes: the cover plate 11, and the first and second adhesive layers 170 and 18 provided on one side of the cover plate. 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. The second adhesion layer comprises a light transmission area and a shading area, the first adhesion layer covers the light transmission area of the second adhesion layer, so that the light transmission area is hidden from being visible on the appearance of the cover plate, a light reflection isolation plate is arranged on the periphery of the light transmission area, and the light reflection isolation plate is used for preventing light of the light transmission area from being diffracted internally in the first adhesion layer.
The color of the top end of the reflective isolation plate is the same as that of the first adhesion layer. The height of the light reflecting isolation plate is equal to the sum of the thicknesses of the first adhesion layer and the second adhesion layer. The reflective separator penetrates through the first adhesion layer and the second adhesion layer.
As an embodiment of the present invention, the top end of the reflective isolation plate is flush with the lower surface of the cover plate.

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. 2, the top non-display area 15 of the cover plate 11 is also provided with a front camera aperture 16, which front camera aperture 16 may be omitted or eliminated in some embodiments.
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. 7.
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.
To meet the requirements of receiving and transmitting light signals from the proximity sensor 20 and the ambient light sensor 30, the second adhesion layer 18 needs to be provided with two light-transmitting areas, namely, a first light-transmitting area 181 for the proximity sensor to transmit light signals and a second light-transmitting area 182 for the proximity sensor to receive light signals or for the ambient light sensor 30 to sense ambient light signals are provided on the second adhesion layer 18.
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 ambient light sensor 30 is located below the second light transmissive area.
As an embodiment of the present invention, the first light-transmitting area 181 and the second light-transmitting area 182 on the second adhesion layer 18 are hollowed out to form a through hole, i.e. the first light-transmitting area 181 and the second light-transmitting area 182 are through holes. Thus, the light signal emitted by the proximity sensor is emitted to the outside through one of the through holes, and the light signal is received by the proximity sensor or is sensed by the ambient light sensor 30 through the other through hole.
As another embodiment of the present invention, on the second adhesive layer 18, the areas other than the first light-transmitting area 181 and the second light-transmitting area 182 are coated with a light-shielding ink (such as black ink), that is, the areas other than the first light-transmitting area 181 and the second light-transmitting area 182 are light-shielding areas. The first and second light transmitting regions 181 and 182 are not coated with a light shielding ink (e.g., black ink). Therefore, the first light-transmitting region 181 and the second light-transmitting region 182 are transparent, so that transmission of the optical signal is not blocked.
The process flow for realizing that the first light transmission area 181 and the second light transmission area 182 are transparent is as follows:
the positions of the first light-transmitting area 181 and the second light-transmitting area 182 on the second adhesion layer 18 are covered by a shielding object, then black ink is coated on the surface of the second adhesion layer 18, finally, the shielding object is removed, so that black ink is formed in other areas except the first light-transmitting area 181 and the second light-transmitting area 182, and the first light-transmitting area 181 and the second light-transmitting area 182 are transparent.
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 around the periphery of 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 around the first light-transmitting region, and a second reflective spacer 184 is disposed around the second light-transmitting region; the first adhesive layer 170 covers and conceals the first light transmitting region 181 and the second light transmitting region 182, and the first reflective spacer 183 and the second reflective spacer 184; wherein the first reflective separator extends downwards from the periphery of the first light transmission area to the position of the signal emitter; the second reflective separator extends downward from the periphery of the second light transmission region to the position of the signal receiver. Namely, the height of the first reflective isolation plate is the distance between the signal emitter and the first adhesion layer group; the height of the second reflective isolation plate is the distance between the signal receiver and the first adhesion layer group.
As shown in fig. 4, as an embodiment of the present invention, when the first light-transmitting area 181 and the second light-transmitting area 182 are through holes, a first reflective spacer 183 having a cylindrical sleeve shape is sleeved over the signal emitter 21 and extends into the through holes of the first light-transmitting area of the second adhesion layer 18; and, in the absence of the ambient light sensor 30, a second reflective spacer 184 in the shape of a cylindrical sleeve is positioned over the signal receiver 22 and extends into the through hole of the second light transmissive region of the second attachment layer 18. It will be appreciated that with the ambient light sensor 30, a second reflective spacer 184 in the form of a cylindrical sleeve is positioned over the signal receiver 22 and the ambient light sensor 30 and extends into the through hole of the second light transmissive region of the second attachment layer 18. 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 and the ambient light sensor 30 to receive the light 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.
As another embodiment of the present invention, grooves are formed on the periphery of the first light-transmitting area 181 and the periphery of the second light-transmitting area 182, the first reflective spacer 183 is sleeved over the signal emitter 21 and extends into the groove formed on the periphery of the first light-transmitting area 181, and the second reflective spacer 184 is sleeved over the signal receiver 22 and extends into the groove formed on the periphery of the second light-transmitting area 182 without the ambient light sensor 30. The area of the first light-transmitting area 181 is greater than or equal to the area of the signal transmitter 21, and the area of the second light-transmitting area 182 is greater than or equal to the area of the signal receiver 22. It will be appreciated that in the case of an ambient light sensor 30, a second reflective spacer 184 is positioned over the signal receiver 22 and the ambient light sensor 30 and extends into a slot formed in the periphery of the second light transmissive region 182.
As a further embodiment of the invention, in addition to the reflective spacers at the second attachment layer 18, reflective spacers are also provided at the first attachment layer set 17 for a more concentrated transmission of the optical signals. The realization is as follows:
a third reflective isolation plate is arranged on the periphery of the first adhesion layer corresponding to the position of the first light transmission area, and a fourth reflective isolation plate is arranged on the periphery of the first adhesion layer corresponding to the position of the second light transmission area; wherein, the top of third reflection of light division board and fourth reflection of light division board all scribbles and is equipped with printing ink that transmits light, so that the colour on third reflection of light division board and fourth reflection of light division board top with the colour on first adhesion layer is the same, just so makes outward appearance colour unanimous, in order to reach pleasing to the eye effect. The third reflective isolation plate is formed by extending a first reflective isolation plate, and the fourth reflective isolation plate is formed by extending a second reflective isolation plate.
As shown in fig. 5, for example, a groove is formed at the periphery of the first adhesion layer at the position corresponding to the first light-transmitting region so that the third reflective separator extends into the groove, and a groove is formed at the periphery of the first adhesion layer at the position corresponding to the second light-transmitting region so that the fourth reflective separator extends into the groove.
As shown in fig. 10, however, it is understood that the first attaching layer group 17 includes three first attaching layers 170, that is, a first attaching layer, a second attaching layer, and a third attaching layer as an example. Preferably, the first adhesive layer is not treated, and only the second first adhesive layer and the third first adhesive layer are provided with grooves 171, so that the reflective spacers extend into the grooves, and thus, the top ends of the reflective spacers do not need to be coated with light-transmitting ink, thereby saving a process.
Alternatively, the first adhesive layer is left untreated, and only the second and third first adhesive layers are provided with through holes which communicate with the through holes of the second adhesive layer 18, as shown in fig. 6. Thus, the reflective isolation plate extends into the inner side wall of the through hole.
In addition, since the first adhesive layer 170 of the outermost layer is not treated, the first adhesive layer 170 of the outermost layer can cover the internal structure of the mobile terminal 1000, so as to achieve the effect of beautifying the mobile terminal 1000. Thus, there is no limitation on the opening of the appearance of the mobile terminal 1000, and therefore, the size and shape of the light-transmitting area on the second adhesive layer 18 are not limited, and the opening can be opened according to the actual light-receiving requirement of the sensing device (generally, the larger the hole is, the better), so that the flexibility of opening and the performances of the proximity sensor 20 and the ambient light sensor 30 are improved.
As shown in fig. 9, the proximity sensing process is as follows: the signal emitter 21 generates an optical signal, and the optical signal is transmitted to the outside through the first light-transmitting area 181 and the first adhesive layer 170, 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 first adhesive layer 170 and the second light-transmitting area 182 after being reflected by the shielding object 70 and the panel 10.
For ambient light sensor 30: ambient light passes through the first adhesive layer 170 and the second light-transmitting region 182, and the ambient light sensor 30 senses the ambient light.
In order to improve the sensing accuracy and performance of the proximity sensor 20, 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.
