Description

Cover plate and terminal

Technical Field

The present invention relates to the field of terminal technologies, and in particular, to a cover plate and a terminal.

Background

Currently, a terminal extinguishes a screen when detecting that a barrier is close to the screen. And lights up the screen when the obstacle is detected to be away from the screen. The entire detection process is mainly performed by a proximity sensor, which typically includes an infrared transmitter and an infrared receiver. The infrared transmitter emits infrared light, and the infrared light is reflected by the obstacle to form reflected light. And after the infrared receiver receives the reflected light, judging whether the obstacle is close to or far away from the terminal according to the received light intensity value.

The non-display area of the touch panel of the terminal is transparent, and in order to make the intelligent terminal more attractive, black infrared ink can be sprayed on the lower surface of the non-display area of a black machine type to cover the internal structure of the terminal.

In general, infrared inks have a relatively high transmittance to infrared light, for example, 85% or more. But the power of the infrared emitter is unchanged, so that the infrared ink of the black machine type has too strong transmittance. Therefore, when the distance between the shielding object and the screen is large, the light intensity value received by the light receiver is larger than the screen-off threshold value, for example, the distance between the shielding object and the screen is 10-15cm, and the accuracy of screen control is poor.

An embodiment of the present invention provides a cover plate, including: the light-emitting diode comprises a first area and a second area, wherein a first adhesion layer is arranged below a cover plate of the first area, a second adhesion layer and a third adhesion layer are arranged below the cover plate of the second area, the transmissivity of the third adhesion layer is smaller than that of the second adhesion layer, and the transmissivity of the first area is smaller than that of the second area.

The embodiment of the invention also provides a terminal, which comprises the cover plate and a sensor assembly arranged on one side of the cover plate, wherein the cover plate and the sensor assembly are arranged at intervals, and the sensor assembly comprises a transmitter and a receiver; the transmitter is used for transmitting a detection signal to the outside; the receiver is used for receiving a detection signal formed after the detection signal is reflected by the obstacle.

The number of the first regions of the cover plate of this embodiment may be 2 or more, and the number of the second regions may be 2 or more.

In one embodiment, the cover plate 10 is suitable for a black terminal, for example, when the housing 200 of the terminal is black, the color of the non-display area of the cover plate 10 is also black. It will be appreciated that the cover plate 10 described above is also suitable for use in terminals of other colours, such as gold, grey etc.

The cover plate of the embodiment is provided with another adhesion layer below the cover plate corresponding to the sensor assembly, and the transmissivity of the next adhesion layer is smaller than that of the previous adhesion layer, so that the transmissivity of the cover plate corresponding to the sensor assembly can be reduced, the screen is prevented from being extinguished when the distance between the shielding object and the screen is large, and the accuracy of terminal screen control is improved.

Referring to fig. 7 to 11, the sensor assembly 20 of the present embodiment is disposed on the circuit board 30, and the sensor assembly 20 includes a transmitter 21 and a first receiver 22, and may further include an ambient light sensor 23.

In one embodiment, the emitter 21 is used to emit infrared light. In some embodiments, the emitter 21 may also be used to emit laser light. In some embodiments, the transmitter 21 may also be used to transmit ultrasound. The emitter 21 is, for example, an infrared emitter or the like, such as an IR LED (infrared light emitting diode).

In one embodiment, the first receiver 22 is configured to receive infrared light. In some embodiments, the first receiver 22 may also be used to receive laser light. In some embodiments, the first receiver 22 may also be used to receive ultrasound.

As shown in fig. 9, the emitter 21 is located below the second area 13, and the first receiver 22 and the ambient light sensor 23 are both located below said second area 13. The detection signal from the transmitter 21 is reflected by the obstacle 40 to form a detection signal, and the first receiver 22 is used to receive the detection signal.

In one embodiment, the detecting light emitted from the transmitter 21 is reflected by a barrier to form an optical signal, and the first receiver 22 is used for receiving the optical signal. The optical signal generated by the transmitter 21 is transmitted to the outside through the second area 13, reflected to the cover 10 after hitting the barrier 40, and then reflected to the barrier 40 by the cover 10, so that after being reflected by the barrier 40 and the cover 10, the optical signal passes through the second adhesion layer 131 and the third adhesion layer 132 and is received by the first receiver 22. Such as a human face, for example.

As shown in fig. 10, for the ambient light sensor 23: the ambient light passes through the second adhesive layer 131 and the third adhesive layer 132, and the ambient light sensor 23 senses the ambient light.

The first receiver 22 and the ambient light sensor 23 may be integrated in one and the same module. In one embodiment, the receiving end of the integrated module can receive both the invisible light emitted by the transmitter 21 and the visible light sensed by the external environment. For example, the integrated module may receive an optical signal such as an infrared signal emitted by the emitter 21, and may sense an ambient light signal.

The sensor module 20 can determine whether the terminal 1000 is close to the face by monitoring the signal emitted by the emitter 21 when the terminal 1000 is in a call, and can turn off the backlight of the screen when the terminal 1000 is determined to be close to the face, thereby saving power and preventing malfunction.

In an embodiment, in practical applications, the sensor assembly 20 can determine whether the terminal 1000 is close to the face by monitoring infrared light emitted from the emitter 21 (e.g., IR LED) when the terminal 1000 is in a call, and can turn off the backlight of the screen when the terminal 1000 is determined to be close to the face, thereby saving power and preventing malfunction. In one embodiment, terminal 1000 can obtain a light intensity value of the first receiver 22, then compare the light intensity value with a preset proximity threshold and a preset distance threshold, respectively, and if the light intensity value is greater than the preset proximity threshold, the terminal extinguishes the screen. And if the light intensity value is smaller than the preset far threshold value, the terminal lights the screen.

In one embodiment, the distance between the transmitter 21 and the first receiver 22 is between 6mm and 14 mm. Preferably, the distance between the transmitter 21 and the first receiver 22 is between 10 mm and 12 mm. The distance between the transmitter 21 and the first receiver 22 is the distance between the geometric center of the transmitter 21 and the geometric center of the first receiver 22.

As shown in fig. 11, the sensor assembly 20 further includes a second receiver 24, the detection signal from the transmitter 21 is reflected by the obstacle 40 to form a near distance signal and a far distance signal, the first receiver 22 is used for receiving the far distance signal, and the second receiver 24 is used for receiving the near distance signal. The second receiver 24 is also located below the second region 13.

In one embodiment, the first receiver 22 and the second receiver 24 are configured to receive infrared light. In some embodiments, the first receiver 22 and the second receiver 24 may also be used to receive laser light. In some embodiments, the first receiver 22 and the second receiver 24 may also be used to receive ultrasound.

In one embodiment, the detecting light emitted from the emitter 21 is reflected by the obstruction 40 to form a low beam signal and a high beam signal, the first receiver 22 is used for receiving the high beam signal, and the second receiver 24 is used for receiving the low beam signal.

When the first receiver 22 is a receiving chip, the range corresponding to the receiving chip is determined by the number of bits of the receiving chip. For example, the ranges of the receiving chips of 8 bits (i.e. 8bit), 10 bits (i.e. 10bit) and 12 bits (i.e. 12bit) are 256, 1024 and 4096, respectively. The first receiver 22 in this embodiment is a receiving chip with a bit number less than or equal to 12 bits, for example, a 10-bit receiving chip may be selected, and at this time, the range corresponding to the receiving chip is 1024. It will be appreciated that the range of the second receiver 24 may not be equal to the range of the first receiver 22.

In practical applications, in an embodiment, terminal 1000 can obtain a first light intensity value of first receiver 22 and a second light intensity value of second receiver 24, then calculate an average value of the first light intensity value and the second light intensity value, compare the average value with a preset approaching threshold and a preset departing threshold, respectively, and if the average value is greater than the preset approaching threshold, turn off the screen. And if the average value is smaller than the preset far threshold value, the terminal lights the screen.

It is understood that the sensor assembly 20 of the present embodiment may be used in combination with any of the cover plates described above.

Referring to fig. 9 to 11, the panel assembly 100 of the present embodiment includes a cover plate 10 and a sensor assembly 20; the transmitter 21 and the first receiver 22 are both located below the second area 13, that is, the transmitter 21 and the first receiver 22 correspond to the location of the second area 13, and the transmitter 21 is configured to transmit a detection signal to the outside through the second area 13. The first receiver 22 is used for receiving a detection signal formed by the reflection of the detection signal emitted by the emitter 21 through the obstacle 40 through the second area 13.

When the sensor assembly 20 includes the ambient light sensor 23, the ambient light sensor 23 is also located below the second region 13, i.e., the ambient light sensor 23 corresponds to the location of the second region 13. The ambient light sensor 23 is used to detect the intensity of ambient light through the second area 13.

When the sensor assembly 20 includes a second receiver 24, the second receiver 24 is also located below the second region 13. The detection signal from the transmitter 21 is reflected by the obstacle 40 to form a near distance signal and a far distance signal, the first receiver 22 is used for receiving the far distance signal, and the second receiver 24 is used for receiving the near distance signal.

It will be appreciated that the cover plate 10 of the panel assembly may be any of the cover plates described above and the sensor assembly 20 of the panel assembly may be any of the sensor assemblies described above. The panel assembly 100 may be a touch panel assembly, a touch panel assembly, a terminal panel assembly with other functions, or the like.

Because the third adhesion layer is arranged below the second adhesion layer of the second area, and the transmissivity of the third adhesion layer is smaller than that of the second adhesion layer, the intensity of a detection signal penetrating through the second area can be reduced, and the detection value of the receiver reaches a preset threshold value when the distance between the obstacle and the receiver is large. When the distance between the obstacle and the receiver is small, the detection value of the receiver reaches the preset threshold value, and the accuracy of screen control is improved.

In an embodiment, because the third adhesion layer is arranged below the second adhesion layer of the second area, because the light transmittance of the third adhesion layer is less than that of the second adhesion layer, therefore, the intensity of the detection light passing through the second area can be reduced, when the distance between the obstacle and the receiver is large, the light intensity value of the receiver reaches the preset threshold value, that is, when the distance between the obstacle and the receiver is small, the light intensity value of the receiver reaches the preset threshold value, the terminal misoperation is avoided, and the accuracy of screen control is improved.

The panel component of this embodiment sets up another adhesion layer again under the adhesion layer through the apron below that corresponds with sensor assembly, because the transmissivity of the later adhesion layer is less than the transmissivity of preceding adhesion layer to can reduce the transmissivity of the apron that corresponds with sensor assembly, avoid sheltering from and extinguish the screen when the interval between thing and the screen is great, improve the accuracy of terminal screen control.

With reference to fig. 1 to 11, the present embodiment further provides a terminal 1000 including: the circuit board 30 is mounted inside the housing 200, and the cover plate 10 is connected to the housing 200.

With reference to fig. 1 to 11, the present embodiment further provides a terminal 1000 including: the sensor assembly comprises a shell 200, a circuit board 30 and a cover plate 10, wherein the circuit board 30 is installed inside the shell 200, the cover plate 10 is connected with the shell 200, and the circuit board 30 comprises any one of the sensor assemblies 20. The sensor assembly 20 is electrically connected to the circuit board 30.

With reference to fig. 1 to 11, the present embodiment further provides a terminal 1000 including: the panel assembly 100 is connected to the housing 200, and the sensor assembly 20 in the panel assembly 100 is electrically connected to the circuit board 30.

The terminal of this embodiment through set up another adhesion layer again under the adhesion layer of the apron below that corresponds with sensor assembly, because the transmissivity of the last adhesion layer is less than the transmissivity of preceding adhesion layer to can reduce the transmissivity of the apron that corresponds with sensor assembly, avoid sheltering from and extinguish the screen when the interval between thing and the screen is great, improve the accuracy of terminal screen control.

The present embodiment further provides a method for adjusting screen brightness, as shown in fig. 12, the method includes:

s101, acquiring a first detection value of a first receiver and a second detection value of a second receiver.

For example, in one embodiment, the detection value is a light intensity value. The terminal may obtain a first light intensity value for the first receiver 22 and a second light intensity value for the second receiver 24. It is understood that the first receiver and the second receiver may have the same structure as those of the above-described embodiment, or may have an existing structure.

S102, calculating an average value of the first detection value and the second detection value.

For example, the terminal calculates an average of the first light intensity value and the second light intensity value.

And S103, comparing the average value with a preset threshold value to obtain a comparison result.

For example, the terminal compares the average value with a preset threshold value to judge whether the obstacle is close to or far from the terminal. The preset threshold may include a preset approach threshold and a preset departure threshold, the preset approach threshold being greater than the preset departure threshold. Wherein step S103 may include:

and S1031, judging whether the average value is larger than a preset approach threshold value.

For example, the terminal determines whether there is an obstacle close to the screen of the terminal. Because the light emitted by the emitter is reflected back to the cover plate by the obstacle when the obstacle approaches, the light intensity value received by the receiver is larger than the preset approaching threshold value. I.e. the average of the light intensity values received by the first receiver or the second receiver is larger than the preset approach threshold. If the terminal determines that the average value is greater than the preset approach threshold, the terminal performs S1032. If the terminal determines that the average value is less than or equal to the preset proximity threshold, the terminal may perform step S1033.

And S1032, if the average value is judged to be larger than the preset approach threshold, determining that the obstacle approaches to the screen of the terminal.

S1033, if the average value is smaller than or equal to the preset approach threshold, determining whether the average value is smaller than a preset departure threshold.

For example, when the terminal determines that no obstacle is close to the terminal, the terminal continues to determine whether the obstacle is far from the screen. Since the light emitted by the emitter is not blocked by the obstacle when the obstacle is far away, the receiver can only receive little light, that is, the light intensity value is less than the preset far away threshold value. If the terminal determines that the average value is smaller than the preset distance threshold, the terminal performs S1034, and if the terminal determines that the average value is greater than or equal to the preset distance threshold, the terminal may return to step S1033.

And S1034, if the average value is smaller than the preset away threshold, determining that the obstacle is away from the screen of the terminal.

And S104, controlling the screen brightness of the terminal according to the comparison result.

For example, the terminal controls the brightness of the screen, such as the turning-off or turning-on operation, according to the comparison result of step S103. Specifically, the step S104 may include:

and S1041, when the terminal judges that an obstacle is close to the screen of the terminal, the terminal extinguishes the screen.

For example, when the terminal determines that an obstacle is close to the terminal, the terminal extinguishes the screen, that is, the luminance value of the screen is minimum.

S1042, when the terminal determines that the barrier is far away from the screen of the terminal, lighting the screen.

For example, when the terminal determines that there is an obstacle far away from the screen, the terminal lights up the screen, that is, the terminal adjusts the brightness value of the screen from the minimum value to the preset display brightness.

Although the above method is exemplified by an optical signal, the present embodiment is not limited thereto. The method of the present embodiment is equally applicable to other types of signals.

Because the existing detection method for detecting whether the obstacle approaches the screen is mainly used for judging through data of a single receiver, the situation of misjudgment is easy to occur.

In the method for adjusting the screen brightness of the embodiment, the first detection value of the first receiver and the second detection value of the second receiver are obtained; calculating an average value of the first detection value and the second detection value; comparing the average value with a preset threshold value to obtain a comparison result; and controlling the screen brightness of the terminal according to the comparison result. Since the average value of the detection values of the two receivers is compared with the preset approaching threshold and the preset departing threshold respectively, the accuracy of judgment is improved.
