Embodiments of the present invention provide a cover plate assembly and a terminal, which will be described in detail below.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a terminal according to an embodiment of the present invention. The terminal 10 includes a cover assembly 11, a housing 12, a receiver 13, a fingerprint film assembly 14, and a control circuit (not shown). Wherein, the cover plate component 11 is installed on the casing 12, and the receiver 13 and the fingerprint module 14 are installed in the casing 12. The cover assembly 11 may be used to receive information input by a user and to display information provided to the user by the terminal 10. The cover plate assembly 11 may include a display area 110 and a non-display area 111. The housing 12 is used to form the outer contour of the terminal 10. The receiver 13 can be used to output an acoustic signal to the outside. Fingerprint module 14 can be used to gather user's fingerprint information. The control circuit may be a motherboard. The control circuit can be electrically connected with the cover assembly 11, the receiver 13 and the fingerprint module 14 to realize the overall monitoring of the terminal 10.

Refer to fig. 2 and 3. The cover assembly 11 may include a signal transmitter 112, a signal receiver 113, a camera 114, an ambient light sensor 115, a cover 116, an attachment layer 117 disposed on the cover 116, and a circuit board 118.

The signal transmitter 112, the signal receiver 113, the camera 114, and the ambient light sensor 115 are disposed on the side of the cover plate 116 having the adhesive layer 117. The signal transmitter 112, the signal receiver 113, the camera 114 and the ambient light sensor 115 are disposed on the circuit board 118 at intervals.

The signal transmitter 112 is used to transmit the probing signal 15. The signal receiver 113 is configured to receive a reflected signal 16 formed by the detection signal 15 being reflected by the external object 1000. The signal may be an optical signal, an acoustic signal, or other types of signals.

The terminal 10 may control the terminal 10 by determining whether the terminal 10 is in a close state or a distant state from the external object 1000 according to the signal intensity value received by the signal receiver 113. For example, when the terminal 10 is in a call state, the terminal 10 determines whether it is in a close state or a distant state with the face of the user. When the terminal is judged to be in a state of being close to the face of the user, the display screen of the terminal can be controlled to be turned off so as to prevent the user from carrying out misoperation on the terminal. And when the terminal is judged to be away from the face of the user, controlling the display screen of the terminal to be lightened.

The camera 114 may be used to capture external images. The ambient light sensor 115 may be used to detect ambient light intensity. The terminal 10 may adjust the display brightness based on the ambient light intensity detected by the ambient light sensor 115.

From outside the terminal 10, the signal transmitter 112, the signal receiver 113, the camera 114 and the ambient light sensor 115 are visible.

In some embodiments, the probe signal 15 emitted by the signal emitter 112 is infrared and the reflected signal 16 received by the signal receiver 113 is also infrared. In some embodiments, the probe signal 15 emitted by the signal emitter 112 is a laser and the reflected signal 16 received by the signal receiver 113 is also a laser. In some embodiments, the probe signal 15 emitted by the signal emitter 112 is an ultrasonic wave, and the reflected signal 16 received by the signal receiver 113 is also an ultrasonic wave.

The cover plate 116 may be a clear glass cover plate. In some embodiments, the cover plate 116 may be a glass cover plate made of a material such as sapphire. An adhesive layer 117 is disposed on the cover plate 116. The adhesion layer 117 includes a first adhesion layer 1171 disposed on one side of the cover plate 116, a second adhesion layer 1172 disposed on one side of the first adhesion layer 1171 away from the cover plate 116, and a through hole 1173 disposed on the adhesion layer 117.

The transmittance of the first adhesive layer 1171 is greater than the transmittance of the second adhesive layer 1172. For example, the transmittance of the first adhesive layer 1171 may be 80% or more than 80%, and the transmittance of the second adhesive layer 1172 may be 10% or less than 10%. In practical applications, the first adhesive layer 1171 can be a signal-transmitting layer for transmitting signals; the second adhesion layer 1172 may be a signal shielding layer for shielding signals. In practical applications, the first adhesion layer 1171 and the second adhesion layer 1172 are configured to conceal the internal structure of the terminal 10 and the second adhesion layer 1172. I.e., such that a user can only see the first attachment layer 1171 and not the second attachment layer 1172 when viewing on the outside of the cover plate 116.

In some embodiments, the first attachment layer 1171 can be a white ink layer and the second attachment layer 1172 can be a black ink layer. Of course, the white ink layer and the black ink layer are only examples, and the first adhesion layer 1171 and the second adhesion layer 1172 can be designed into other colors according to different aesthetic requirements as long as the transmittance of the first adhesion layer 1171 is greater than that of the second adhesion layer 1172. The white ink layer, the black ink layer or the ink layers with other colors can be manufactured through a spraying or printing process.

The transmittance may include one or more of transmittance for infrared rays, transmittance for laser light, transmittance for visible light, and transmittance for ultrasonic waves.

In some embodiments, the first attachment layer 1171 can be a single layer, and the second attachment layer 1172 can be a single layer or multiple layers; alternatively, the first attachment layer 1171 may be multi-layered and the second attachment layer 1172 may be single-layered or multi-layered.

The spacing between the camera head 114 and the cover plate 116 may be zero. The through hole 1173 is also located opposite to the signal transmitter 112, the signal receiver 113 and the ambient light sensor 115, so that the detection signal 15 transmitted by the signal transmitter 112 is not blocked by the adhesion layer 117 and can be transmitted to the outside through the cover plate 116, the reflected signal 16 formed by the detection signal 15 being reflected by the external object 1000 can enter the signal receiver 113 without being blocked by the adhesion layer 117 after being transmitted through the cover plate 116, and the ambient light can enter the ambient light sensor 115 without being blocked by the adhesion layer 117 after being transmitted through the cover plate 116.

In some embodiments, as shown in fig. 4, the ambient light sensor 115 is disposed opposite the second adhesive layer 1172, i.e., the location of the through hole 1173 is not opposite the location of the ambient light sensor 115. At this time, the ambient light sensor 115 is not visible from the outside of the terminal 10. The cover plate assembly 11 may also include a reflective structure 119.

The signal transmitter 212, the signal receiver 213, the camera 214 and the ambient light sensor 215 are disposed on the circuit board 218 at intervals.

The signal transmitter 212 is used to transmit the probing signal 25. The reflective structure 219 is disposed on the transmission path of the probe signal 25 to change the transmission path of the probe signal 25. Wherein the reflective structure 219 may be disposed on the circuit board 218. The signal receiver 213 is used for receiving a reflected signal 26 formed by the detection signal 25 reflected by the external object 2000. The signal may be an optical signal, an acoustic signal, or other types of signals.

The terminal 20 may control the terminal 20 by determining whether the terminal 20 is in a close state or a distant state from the external object 2000 based on the signal intensity value received by the signal receiver 213. For example, when the terminal 20 is in a call state, the terminal 20 determines whether it is in a close state or a distant state with the face of the user. When the terminal is judged to be in a close state with the face of the user, the display screen of the terminal can be controlled to be turned off so as to prevent the user from carrying out misoperation on the terminal. And when the terminal is judged to be away from the face of the user, controlling the display screen of the terminal to be lightened.

The camera 214 may be used to capture external images. The ambient light sensor 215 may be used to detect ambient light intensity. The terminal 20 may adjust the display screen brightness based on the ambient light intensity detected by the ambient light sensor 215.

From outside the terminal 20, the signal receiver 213, the camera 214 and the ambient light sensor 215 are all visible, and the signal transmitter 212 is not visible.

In some embodiments, the probe signal 25 emitted by the signal emitter 212 is infrared and the reflected signal 26 received by the signal receiver 213 is also infrared. In some embodiments, the probing signal 25 emitted by the signal emitter 212 is a laser, and the reflected signal 26 received by the signal receiver 213 is a laser. In some embodiments, the probe signal 25 transmitted by the signal transmitter 212 is an ultrasonic wave, and the reflected signal 26 received by the signal receiver 213 is also an ultrasonic wave.

The cover 216 may be a clear glass cover. In some embodiments, the cover plate 216 may be a glass cover plate made of a material such as sapphire. An adhesion layer 217 is disposed on the cover plate 216. The adhesion layer 217 includes a first adhesion layer 2171 disposed on one side of the cover plate 216, a second adhesion layer 2172 disposed on the first adhesion layer 2171 on a side away from the cover plate 216, and a through hole 2173 disposed on the adhesion layer 217.

The transmittance of the first adhesive layer 2171 is greater than the transmittance of the second adhesive layer 2172. For example, the transmittance of the first adhesive layer 2171 may be 80% or more, and the transmittance of the second adhesive layer 2172 may be 10% or less. In practical applications, the first adhesive layer 2171 may be a signal-transmitting layer for transmitting signals; the second adhesive layer 2172 may be a signal shielding layer for shielding signals. In practical applications, the first adhesive layer 2171 and the second adhesive layer 2172 are disposed to hide the internal structure of the terminal 20 and the second adhesive layer 2172. I.e., such that a user can see only the first adhesive layer 2171 and not the second adhesive layer 2172 when viewing outside the cover sheet 216.

In some embodiments, the first adhesive layer 2171 can be a white ink layer and the second adhesive layer 2172 can be a black ink layer. Of course, the white ink layer and the black ink layer are only examples, and the first adhesive layer 2171 and the second adhesive layer 2172 can be designed into other colors according to different aesthetic requirements as long as the transmittance of the first adhesive layer 2171 is greater than that of the second adhesive layer 2172. The white ink layer, the black ink layer or the ink layers with other colors can be manufactured through a spraying or printing process.

In some embodiments, the first adhesive layer 2171 may be a single layer, the second adhesive layer 2172 is a single layer or multiple layers; alternatively, the first adhesive layer 2171 may be a plurality of layers, and the second adhesive layer 2172 may be a single layer or a plurality of layers.

One end of the camera 214 is disposed in the through hole 2173, so that the camera 214 can capture an external image through the cover 216. The spacing between the camera 214 and the cover 216 may be zero. The through hole 2173 is also located opposite to the signal receiver 213 and the ambient light sensor 215, so that the reflected signal 26 formed by the reflection of the detection signal 25 emitted by the signal emitter 212 by the external object 2000 can enter the signal receiver 213 without being blocked by the adhesive layer 217 after passing through the cover plate 216, and the ambient light can enter the ambient light sensor 215 without being blocked by the adhesive layer 217 after passing through the cover plate 216.

At this time, the signal transmitter 212 is not visible from the outside of the terminal 20. The reflecting structure 219 is disposed on the transmission path of the detection signal 25. After the detection signal 25 emitted from the signal emitter 212 reaches the reflection structure 219, the reflection structure 219 changes the transmission path of the detection signal 25, so that the detection signal 25 is emitted to the outside through the through hole 2173 and through the cover 216. The detection signal 25 is reflected by the external object 2000 to form a reflected signal 26, and the reflected signal 26 passes through the cover plate 216 and enters the signal receiver 213 through the through hole 2173. In some embodiments, the reflective structure 219 may be a flat mirror.

Wherein the signal emitter 312 and the signal receiver 313 are disposed at positions opposite to the second adhesive layer 3172, i.e., the positions of the through holes 3173 are not opposite to the positions of the signal emitter 312 and the signal receiver 313. At this time, the signal transmitter 312 and the signal receiver 313 are not visible from the outside of the terminal 30. The reflective structure 319 is disposed on the transmission path of the detection signal 35. After the detection signal 35 emitted from the signal emitter 312 reaches the reflection structure 319, the reflection structure 319 changes the transmission path of the detection signal 35, so that the detection signal 35 is emitted to the outside through the through hole 3173 and through the cover plate 316. The detection signal 35 is reflected by an external object 3000 to form a reflected signal 36. The reflective structure 320 is disposed on a transmission path of the reflected signal 36. After the reflected signal 36 reaches the reflective structure 320 through the cover plate 316, the reflective structure 320 changes the transmission path of the reflected signal 36, so that the reflected signal 36 enters the signal receiver 313. In some embodiments,

reflective structures

319 and 320 may be flat mirrors.

In some embodiments, an ambient light sensor 315 may also be disposed opposite the second adhesive layer 3172. A reflective structure may be disposed on the transmission path of the ambient light, so that the ambient light enters the ambient light sensor 315 after changing the transmission path.

In practical application, the method for the terminal to judge whether the terminal is in a close state or a far state with an external object is as follows:

the signal transmitter transmits a detection signal, the detection signal forms a reflection signal after being reflected by an external object, and the reflection signal enters the signal receiver. The terminal judges whether the terminal is in a close state or a distant state with respect to an external object according to the signal intensity detected by the signal receiver. When the signal intensity value detected by the signal receiver is greater than a preset threshold value, the terminal and an external object are judged to be in a close state; and when the signal intensity value detected by the signal receiver is smaller than or equal to a preset threshold value, judging that the terminal and the external object are in a far state. Wherein, the preset threshold value may be a signal strength value preset in advance. For example, the preset threshold is 500, and it may be determined that the terminal is in the close state when the detected signal strength value is 600, and it may be determined that the terminal is in the far state when the detected value is 400.
