An embodiment of the present application provides an electronic device. The electronic device may be a smart phone, a tablet computer or the like. Referring to FIG. 1 , an electronic device 100 includes a cover plate 10 , a display panel assembly 20 , a circuit board 30 and a casing 40 .

The display screen assembly 20 serves as the front shell of the electronic device 100 and forms a closed space with the casing 40 for accommodating other electronic components of the electronic device 100 . Meanwhile, the display screen assembly 20 forms a display surface of the electronic device 100 for displaying information such as images and texts.

In some embodiments, the display screen 21 in the electronic device 100 can be displayed in full screen. That is, the display screen 21 only includes a display area and does not include a non-display area, as shown in FIG. 2 .

The circuit board 30 is installed inside the casing 40 to accommodate the circuit board 30 in the above-mentioned closed space. The circuit board 30 may be a main board of the electronic device 100 . A grounding point is provided on the circuit board 30 to realize the grounding of the circuit board 30 . Functional components such as a camera and a processor may be integrated on the circuit board 30 . Meanwhile, the display screen assembly 20 may be electrically connected to the circuit board 30 .

In some embodiments, a display control circuit is disposed on the circuit board 30 . The display control circuit outputs electrical signals to the display screen assembly 20 to control the display screen assembly 20 to display information.

The casing 40 is used to form the outer contour of the electronic device 100 . The material of the housing 40 can be plastic or metal. The housing 40 can be integrally formed.

In some embodiments, as shown in FIG. 3 , the display screen assembly 20 includes a display screen 21 and a sensor assembly 22 . Wherein, the sensor assembly 22 is arranged on one side of the display screen 21 .

It can be understood that the sensor assembly 23 is disposed inside the display screen 21 . Wherein, the inner side refers to the side where the display screen 21 is not visible when viewed from the outside of the electronic device 100 . That is, the sensor assembly 22 is located inside the electronic device 100 .

Wherein, the sensor component 22 may include a plurality of signal transmitters 221 and a signal receiver 222 . The detection signals emitted by each signal transmitter 221 have different wavelengths, and the signal transmitters 221 transmit detection signals A outward according to their signal transmission frequency intervals. The detection signals A are transmitted to the outside world through the display screen 21, and the detection signals A pass through external objects. After 200 (for example, the user's face), the reflected signal B is generated. The reflected signal B enters the signal receiver 222 through the display screen 21 .

In some embodiments, the signal transmitter 221 is an infrared transmitter for emitting infrared rays. The signal receiver 222 is an infrared receiver for receiving infrared rays.

Wherein, the wavelength of infrared rays is between 760 nanometers (nm) and 1 mm.

In some embodiments, when the signal transmitter 221 is an infrared transmitter, the wavelength of the signal emitted by the signal transmitter 221 may be a wavelength value between 760nm and 1mm. For example, 770nm, 780nm, 790nm, 800nm and so on.

For example, in some embodiments, when there are three signal transmitters 221 , the detection signals emitted by the three signal transmitters 221 have different signal wavelengths. Can be 770nm, 800nm, 890nm respectively.

In some embodiments, the signal wavelengths of the signals transmitted by the signal transmitters 221 are sequentially increasing, so that the signal receiver 222 can receive the detection signals of each signal transmitter 221 in sequence, and the detection signals of each signal transmitter 221 can not be received. Overlap can improve the accuracy of detection signal reception, improve the accuracy of proximity sensing or detection, and then improve the accuracy of display state control.

Wherein, the number of signal transmitters 221 can be set according to actual needs, for example, it can be 2, 3, 4 and so on.

In some embodiments, referring to FIG. 4 , a plurality of signal transmitters 221 are arranged around the signal receiver 222 at intervals; it can be understood that the signal transmitters 221 are arranged around the signal receiver 22 . Since the signal transmitters 221 are arranged at intervals around the signal receiver 222, the loss of detection signals can be reduced, the signal receiving effect of the signal receiver 222 can be improved, and the accuracy of proximity sensing or detection can be improved.

In some embodiments, the signal transmitters 221 with different signal transmission frequencies have different distances from the signal receiver 222 . When the signal transmission frequencies of at least two signal transmitters 221 are different, the distances between the at least two signal transmitters 221 and the signal receiver 222 are also different.

In some embodiments, under the condition of the same signal transmission speed, the larger the wavelength, the greater the signal energy, and the better the penetration. Therefore, in order to ensure that the detection signal with small signal energy can be received by the signal receiver 222, the signal transmission The longer the signal wavelength of the transmitter 221 is, the smaller the distance between it and the signal receiver 222 is;

In addition, setting different distances for signal transmitters with different signal wavelengths can also reduce the detection signal delay of the signal transmitter 221 with a larger signal wavelength, ensure that the signal receiver 222 can receive the detection signal in time, and prevent other signals from being transmitted. The interference of the detection signal of the detector 221 to the reception improves the signal reception effect of the signal receiver 222, thereby improving the accuracy of proximity sensing or detection.

For example, referring to FIG. 5 , the signal wavelength of the left signal transmitter 221 is greater than that of the right signal transmitter 221 , and the signal wavelength of the top signal transmitter 221 is greater than that of the left signal transmitter 221 . Therefore, the distance d1 between the top signal transmitter 221 and the signal receiver 222 is smaller than the distance d2 between the left signal transmitter 221 and the signal receiver 22, and the distance between the left signal transmitter 221 and the signal receiver 22 d2 is smaller than the distance d3 between the right signal transmitter 221 and the signal receiver 22 .

Since the signal transmitter 221 with a smaller transmission frequency is close to the signal transmitter 221, the delay in receiving the detection signal of the signal transmitter 221 by the signal transmitter 221 can be reduced, and the detection signal sent by the signal transmitter 221 can be received in time, It is avoided that the reception of the detection signals of other signal transmitters 221 interferes with the reception of the detection signals of the signal transmitter 221 due to reception delay, and the detection signals of the signal transmitter 221 interfere with the reception.

In some embodiments, the distance between the signal transmitter 221 and the signal receiver 222 is between 2 mm and 14 mm. Experiments show that within this distance range, a better proximity sensing effect can be achieved with high accuracy.

In some embodiments, the distance between the signal transmitter 221 and the signal receiver 222 may include: the distance between the geometric center of the signal transmitter 221 and the geometric center of the signal receiver 222 . The distance between the signal transmitter 221 and the signal receiver 222 can also improve the isolation between the signal transmitter 221 and the signal receiver 222 , and reduce the impact of the signal transmitted by the signal transmitter 221 on the signal receiver 222 .

It can be understood that the ambient light sensor 223 , the signal transmitter 221 and the signal receiver 222 are disposed inside the display screen 21 .

For example, when the ambient light sensor 223 detects that the external ambient light signal becomes weaker, the processor can increase the brightness of the display screen 21 , and when the ambient light sensor 223 detects that the external ambient light signal becomes stronger, the processor can reduce the brightness of the display screen 21 .

The influence caused by the signal receiver 222 and the ambient light sensor 233 .

In some embodiments, in order to reduce the interference or influence of the signal emitted by the signal transmitter 221 on the ambient light sensor 233, the distance between the ambient light sensor 223 and the signal receiver 222 may be greater than the distance between the signal transmitter 221 and the signal receiver 222 distance between. It can be understood that the distance between the ambient light sensor 223 and the signal receiver 222 is the distance between the geometric center of the ambient light sensor 223 and the geometric center of the signal receiver 222 .

An embodiment of the present application provides a method for controlling a display screen, which is suitable for electronic equipment. The electronic device includes the display screen component provided in any one of the embodiments of the present application. The display screen control method controls the state of the display screen according to the state of the distance between the electronic device and the external object. The distance state includes a far state and an approach state. The status of the display includes on and off. The display control method is described below.

In some embodiments, a method for controlling a display screen is also provided. Referring to FIG. 13 , the specific flow of the method is as follows:

S501. Obtain signal strength values corresponding to signal transmitters within a preset time period to obtain a set of strength values.

Wherein, the signal strength value is a signal strength value at which the signal receiver detects the detection signal transmitted by the signal transmitter. For example, the signal strength corresponding to the signal transmitter is the strength of the detection signal transmitted by the signal transmitter a detected by the signal receiver.

Wherein, the set of strength values includes a signal strength value corresponding to each signal transmitter.

Wherein, the preset time period may be set according to actual needs, for example, 10s, 5s and so on. In order to improve the accuracy of intensity acquisition, the preset time period may be determined based on the signal transmission period T of the signal transmitter, for example, 2T, 3T and so on.

Taking three signal transmitters as an example, the signal strength value c1 corresponding to signal transmitter a, the signal strength value c2 corresponding to signal transmitter b, and the signal strength value c3 corresponding to signal transmitter c can be obtained respectively.

In some embodiments, multiple signal strength values corresponding to the signal transmitter can be obtained within a preset time period, that is, multiple actual signal strengths. In order to facilitate the control of the display screen state, the average signal strength corresponding to the signal transmitter can be calculated. Take the average signal strength as the signal strength corresponding to the signal transmitter. For example, the step of "obtaining the signal strength value corresponding to the signal transmitter within the preset time period" may include:

Acquiring a plurality of actual signal strength values corresponding to the signal transmitter within a preset time period;

Obtain an average signal strength value corresponding to the signal transmitter according to the plurality of signal strength values;

The average signal strength value is used as the signal strength value corresponding to the signal transmitter.

For example, taking the signal transmitter a as an example, the signal transmitter a transmits detection signals at regular intervals, and the signal receiver detects the detection signals transmitted by the signal transmitter a, so that multiple actual signals corresponding to the signal transmitter a can be obtained Strength values, such as n actual signal strength values c11, c12, ... c1n, where n is a positive integer greater than 2. At this time, the average signal strength value c'=(c11+c12+...+c1n)/n of the signal transmitter a can be obtained, and the average signal strength value c' of the signal transmitter a is the corresponding signal strength of the signal transmitter a value c1.

S502. Obtain the signal wavelength of the signal transmitted by the signal transmitter.

Wherein, the signal wavelength of the signal transmitted by the signal transmitter is the wavelength of the detection signal transmitted by the signal transmitter.

For example, the signal wavelength of the signal transmitter a is λ1, the signal wavelength of the signal transmitter b is λ2, and the signal wavelength of the signal transmitter c is λ3.

S503. Process the strength value set according to the signal wavelength to obtain a target signal strength value.

In some embodiments, the signal strength values of the set of strength values may be summed based on the signal wavelength.

For example, based on the signal wavelength of signal transmitter a being λ1, the signal wavelength of signal transmitter b being λ2, and the signal wavelength of signal transmitter c being λ3, the signal strength value c1 corresponding to signal transmitter a and the signal strength value c1 of signal transmitter b The corresponding signal strength value c2 and the signal strength value c3 corresponding to the signal transmitter c are summed to obtain a target signal strength value c.

In some embodiments, in order to improve the accuracy of the state control of the display screen, weighted summation processing may be performed on the signal strength values, wherein the signal wavelength of the signal transmitter may correspond to the weight value. The step of "processing the intensity value set according to the signal wavelength to obtain a target signal intensity value" may include:

Acquiring a weight value corresponding to the signal wavelength;

performing weighted summation on the signal strength values in the strength value set according to the weight value to obtain a weighted sum value;

A corresponding target signal strength value is obtained according to the weighted sum value.

For example, obtain the weight value q1 corresponding to the signal wavelength λ1 of signal transmitter a, the weight value q2 corresponding to the signal wavelength λ2 of signal transmitter b, and the weight value q3 corresponding to the signal wavelength λ3 of signal transmitter c; then, calculate the signal strength Weighted sum Q=c1*q1+c2*q2+c3*q3; finally, the required target signal strength value is obtained based on the weighted sum Q of signal strength. For example, the signal strength weighted sum Q may be used as the required target signal strength value.

In some embodiments, the mapping relationship between the signal wavelength and the weight value can be preset, so that after acquiring the signal wavelength of the signal transmitter, the corresponding weight value can be obtained based on the mapping relationship.

In some embodiments, the wavelength can also be divided into several wavelength ranges, and then each wavelength range corresponds to a weight value, so that after obtaining the signal wavelength, determine the wavelength range in which the signal wavelength falls, and then obtain the wavelength The weight value corresponding to the range.

For example, the signal wavelength of the signal transmitter a is λ1=800nm. At this time, λ1 falls within the wavelength range (780nm, 820nm), and the weight value q1=0.3 corresponding to the wavelength range (780nm, 820nm) can be obtained. Similarly, the signal wavelength λ2=900 of the signal transmitter b falls into the wavelength range (880nm, 930nm), and the weight value q2=0.4 corresponding to the wavelength range. The signal wavelength λ3=950 of the signal transmitter c falls into the wavelength range (940nm, 990nm), and the weight value q3=0.3 corresponding to the wavelength range.

In some embodiments, in order to improve the accuracy of the state control of the display screen, the signal strength value of the corresponding wavelength may be compensated, and then the target signal strength value may be obtained based on the compensated strength value. For example, the step "processing the intensity value set according to the signal wavelength to obtain a target signal intensity value" may include:

Selecting a target signal wavelength whose wavelength is greater than a preset wavelength threshold from the signal wavelengths transmitted by the signal transmitter;

Compensating the signal strength value corresponding to the target signal wavelength in the strength value set to obtain a compensated strength value set;

A summation operation is performed on the signal strength values in the compensated strength value set to obtain the target signal strength value.

Since the signal with a larger wavelength has less energy and weaker penetrating power, the signal received by the signal receiver is weaker and the intensity value is smaller, which will affect the calculation accuracy of approach or distance. The embodiment of the present application can compensate the received signal value with a relatively large wavelength, so that the calculation accuracy of approach or distance can be improved, thereby improving the control accuracy of the status of the display screen.

Wherein, the preset wavelength threshold λ' can be set according to time requirements, for example, when an infrared signal is emitted, the predicted wavelength threshold can be 900nm, 990nm and so on.

For example, the signal wavelength of signal transmitter a is λ1, the signal wavelength of signal transmitter b is λ2, and the signal wavelength of signal transmitter c is λ3; if λ1 is greater than λ', at this time, the signal corresponding to signal transmitter a can be The strength value c1 is compensated, and then the summed c1, the strength value c2 of the signal transmitter b, and the strength value c3 of the signal transmitter c are summed to obtain the sum of the strength values, and the target is obtained based on the sum of the strength values For the signal strength value, for example, the sum of the strength values may be used as the target signal strength value.

In some embodiments, the manner of compensating the signal strength may include: increasing the signal strength value by a preset ratio, or by a preset amount. For example, the signal strength value c1 may be increased by 40 percent and so on.

S504. Control the state of the display screen according to the target signal strength value and the signal strength threshold.

Wherein, the state of the display screen includes on and off.

For example, the target signal strength value may be compared with a signal strength threshold, and the state of the display screen may be controlled based on the comparison result.

In practical applications, when the electronic device needs to control the state of the display screen, it can control the state of the display screen according to the target signal strength value and the signal strength threshold. For example, when the electronic device is in a voice call state, the state of the display screen is controlled. At this time, when the user's face is close to the display screen, the display screen can be controlled to turn off, so as to prevent the user from causing misoperation on the display screen. When the user's face is away from the display screen, the control display screen lights up to restore the normal display of the display screen.

In some embodiments, considering that the detection signal will attenuate during the transmission process, if the signal strength threshold is fixed, such as using a preset signal strength value, then it will lead to inaccurate judgment of approach or distance, which will cause the display Screen state control is less accurate. Therefore, in order to improve the accuracy of approach or distance judgment, the threshold can be changed based on the threshold subtraction coefficient corresponding to the current signal strength value, so as to adapt to the proximity detection under the current signal strength value.

Wherein, the step "controlling the state of the display screen according to the target signal strength value and the signal strength threshold" may include:

Acquiring the signal strength interval where the target signal strength value is located;

Acquiring a threshold attenuation coefficient corresponding to the signal strength interval;

Acquiring a corresponding signal strength threshold according to the initial signal strength threshold and the threshold attenuation coefficient;

The state of the display screen is controlled according to the target signal strength value and the signal strength threshold.

Wherein, the threshold attenuation coefficient is an attenuation ratio of the signal strength threshold, for example, it may be 30 percent or the like.

For example, to obtain the signal strength region (ci, cj] where the target signal strength value c is located, the threshold attenuation coefficient corresponding to the signal strength region (ci, cj] is p, assuming that the initial signal strength threshold is y, at this time, the final The signal strength threshold of Y=y-y*p.

For example, if the target signal strength value acquired by the electronic device is 100, the signal strength interval of the target signal strength value is (43, 159]. Then, the electronic device can obtain the signal strength interval (43, 159] corresponding to The threshold attenuation coefficient is 30%. The initial signal strength threshold is 300. At this time, the signal strength threshold is 300-300*30%=210.

In some embodiments, the signal strength threshold may include a first threshold; at this time, the step of "controlling the state of the display screen according to the target signal strength value and the signal strength threshold" may include:

When the display screen is in a bright screen state, judging whether the target signal strength value is greater than the first threshold;

If the target signal strength value is greater than the first threshold, the display screen is controlled to turn off.

Wherein, the signal strength threshold includes a first threshold. The first threshold may be a high threshold. The high threshold is used to trigger and control the display screen to turn off when the display screen is in a bright screen state.

When the display screen of the electronic device is in the bright screen state, after the electronic device obtains the target signal strength value, it compares the target signal strength value with the first threshold value to determine whether the target signal strength value is greater than the first threshold value. a threshold. When it is determined that the target signal strength value is greater than the first threshold, it indicates that the electronic device is in a close state to an external object (for example, the user's face), and at this time, the control display screen is turned off. When it is determined that the target signal strength value is less than or equal to the first threshold, it means that the electronic device is not in a close state to an external object (for example, the user's face), and at this time, the electronic device maintains the display screen in a bright state .

For example, if the first threshold value is 243.9, and the second signal strength value acquired by the terminal is 400, then the target signal strength value is greater than the first threshold value at this time, and the terminal controls the display screen to turn off.

In some embodiments, the signal strength threshold may include a second threshold; the step of "controlling the state of the display screen according to the target signal strength value and the signal strength threshold" may include:

When the display screen is in a screen-off state, judging whether the target signal strength value is less than a second threshold;

If the target signal strength value is less than the second threshold, the display screen is controlled to be turned on.

Wherein, the signal strength threshold includes a second threshold. The second threshold may be a low threshold. The low threshold is used to trigger and control the display screen to turn on when the display screen is in the off state. For the same electronic device in the same external environment, the low threshold is smaller than the above high threshold.

When the display screen of the electronic device is in the off-screen state, after the electronic device obtains the target signal strength value, it compares the target signal strength value with the second threshold value to determine whether the target signal strength value is smaller than the first threshold value. Two thresholds. When it is determined that the target signal strength value is less than the second threshold, it means that the electronic device is in a state of being far away from the external object (for example, the user's face), and at this time, the control display screen is turned on. When it is determined that the target signal strength value is greater than or equal to the second threshold, it means that the electronic device is not far away from the external object (for example, the user's face), and at this time, the electronic device maintains the display screen in the off-screen state .

For example, if the second threshold value is 200, and the target signal strength value obtained by the electronic device is 180, then at this time, the target signal strength value is smaller than the second threshold value, and the electronic device controls the display screen to light up.

During specific implementation, the present application is not limited by the execution order of the described steps, and some steps may be performed in other orders or simultaneously in the case of no conflict.

Considering that the proximity sensor is currently installed under the display screen, but due to the obstruction of the display screen and the weak penetration ability of the detection signal, the signal strength received by the signal receiver will be weak, and the electronic device cannot accurately identify the approaching or away status. , which in turn leads to lower accuracy in controlling the state of the display screen.

In addition, the method provided by the embodiment of the present application can also obtain the corresponding signal strength threshold based on the signal strength of multiple signal transmitters, so that the signal strength threshold can be associated with the external environment, which can reduce the impact caused by the detection of the proximity sensor by the external environment. Therefore, the accuracy of proximity or distance detection can be further improved.
