The display screen 21 is mounted on the housing 40 to form a display surface of the electronic device 100. The display screen 21 serves as a front case of the electronic device 100 and forms a closed space with the housing 40 for accommodating other electronic components of the electronic device 100. At the same time, the display screen 21 forms a display surface of the electronic device 100 for displaying information such as images, texts, and the like.

In the description of the present application, it should be noted that the terms "installation", "connected", and "connected" are to be understood broadly, and may be fixed or detachable, for example, unless otherwise specifically defined and defined. Connected, or integrally connected; may be mechanically connected, may be electrically connected or may communicate with each other; may be directly connected, or may be indirectly connected through an intermediate medium, may be internal communication of two elements or interaction of two elements relationship. For those skilled in the art, the specific meanings of the above terms in the present application can be understood on a case-by-case basis.

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

The circuit board 30 is mounted inside the casing 40 to house the circuit board 30 in the enclosed space. Circuit board 30 can be the motherboard of electronic device 100. A grounding point is provided on the circuit board 30 to achieve grounding of the circuit board 30. Functional components such as a camera, a processor, and a sensor can be integrated on the circuit board 30. At the same time, the display 21 can be electrically connected to the circuit board 30.

In some embodiments, display control circuitry is provided on circuit board 30. The display control circuit outputs an electrical signal to the display screen 21 to control the display screen 21 to display information.

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

In some embodiments, as shown in FIG. 3, sensor assembly 22 is disposed on circuit board 30. The sensor assembly 22 is located on one side of the display screen 21.

It will be appreciated that the sensor assembly 23 is disposed on the inside of the display screen 21. Here, 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.

The sensor component 22 can include a plurality of signal transmitters 221 and a signal receiver 222. Each signal transmitter 221 corresponds to or sets a signal transmission frequency, and the signal transmitter 221 transmits a detection signal A according to its signal transmission frequency interval. The detection signal A is transmitted to the outside through the display screen 21, and the detection signal A passes through the external object 200. After (for example, the user's face), a reflected signal B is generated. The reflected signal B enters the signal receiver 222 through the display 21.

The signal transmission frequencies of the at least two signal transmitters 221 are different. For example, when there are five signal transmitters 221, two of the signal transmitters 221 have different transmission frequencies, and the other three signal transmitters 221 The transmission frequency is the same.

In some embodiments, the signal transmission frequencies of all of the signal transmitters 221 are different, for example, when there are three signal transmitters 221, wherein the signal transmission frequencies of the three signal transmitters 221 are different. Referring to FIG. 4, the signal transmission reference clocks of the three signal transmitters 221 (taking pulse signals as an example) are respectively T1 and T2 to T3. As can be seen from FIG. 4, the signal transmission reference clocks of the three signal transmitters 221 have different periods. That is, the signal transmission frequency is different, and the signal transmitter 221 sends a detection signal when it arrives at the rising edge of each pulse.

In some embodiments, the signal transmission frequency of the signal transmitter 221 is sequentially increased, so that the signal receiver 222 can sequentially receive the detection signals of the signal transmitters 221, and the detection signals of the respective signal transmitters 221 do not overlap. It can improve the accuracy of the detection signal reception, improve the accuracy of proximity sensing or detection, and thus improve the accuracy of the display state control.

The number of the 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. 5, a plurality of signal transmitters 221 are respectively disposed around the signal receiver 222; it is understood that the signal transmitter 221 is disposed around the signal receiver 22. Since the signal transmitters 221 are respectively disposed around the signal receiver 222, the loss of the detection signal can be reduced, and the signal receiving effect of the signal receiver 222 can be improved, thereby improving the accuracy of proximity sensing or detection.

When the signal transmission frequencies of at least two signal transmitters 221 are different, then the distance between the at least two signal transmitters 221 and the signal receiver 222 is also different.

In some embodiments, the greater the signal transmission frequency of the signal transmitter 221, the greater the distance between the signal transmitter 222 and the signal receiver 222; otherwise, the smaller the signal transmission frequency of the signal transmitter 221, between the signal receiver 222 and the signal receiver 222 The smaller the distance.

In this way, the detection signal delay of the signal transmitter 221 with a small signal transmission frequency can be reduced, the signal receiver 222 can receive the detection signal in time, and the interference of the detection signal of the other signal transmitter 221 can be prevented, and the signal reception can be improved. The signal receiving effect of the device 222, thereby improving the accuracy of proximity sensing or detection.

For example, referring to FIG. 6, the signal transmission frequency of the signal transmitter 221 on the left is greater than the signal transmission frequency of the signal transmitter 221 on the right, and the signal transmission frequency of the signal transmitter 221 on the top is greater than that of the signal transmitter 221 on the left. 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 signal transmitter 221 on the right and the signal receiver 22.

Since the signal transmitter 221 with a small transmission frequency is brought close to the signal transmitter 221, the delay of the signal transmitter 221 receiving the detection signal of the signal transmitter 221 can be reduced, and the detection signal sent by the signal transmitter 221 can be received in time. The reception of the detection signal to the other signal transmitter 221 due to the reception delay is prevented from interfering with the detection signal reception of the signal transmitter 221, and the interference of the detection signal of the signal transmitter 221 is received.

In some embodiments, the distance between the signal emitter 221 and the signal receiver 222 is between 2 and 14 millimeters. Experiments have shown that this range of distances can have a better proximity sensing effect with high accuracy.

The signal transmitter 221 and the signal receiver 222 are spaced apart from each other to also improve the isolation between the signal transmitter 221 and the signal receiver 222, and reduce the influence of the signal transmitted by the signal transmitter 221 on the signal receiver 222.

For example, when the ambient light sensor 223 detects that the ambient light signal is weak, the processor can increase the brightness of the display screen 21. When the ambient light sensor 223 detects that the ambient light signal becomes strong, the processor can reduce the brightness of the display screen 21.

In some embodiments, signal transmitter 221, signal receiver 222, and ambient light sensor 223 are spaced apart from one another. The distance between the signal transmitter 221 and the signal receiver 222 is between 2 and 14 millimeters. It will be appreciated that the above distance is the distance between the geometric center of the signal transmitter 221 and the geometric center of the signal receiver 222. The signal transmitter 221, the signal receiver 222, and the ambient light sensor 223 are spaced apart from each other to improve the isolation between the signal transmitter 221, the signal receiver 222, and the ambient light sensor 223, and reduce the signal pair transmitted by the signal transmitter 221. The effects 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 transmitted 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 that of the signal transmitter 221 and the signal receiver 222. The distance between them. It will be appreciated that the distance between ambient light sensor 223 and signal receiver 222 is the distance between the geometric center of ambient light sensor 223 and the geometric center of signal receiver 222.

The distance state includes a distant state and a proximity state. The status of the display includes lighting and extinguishing. The display control method will be described below.

The embodiment of the present application further provides a display control method, which is applicable to the electronic device introduced above, and includes:

Obtaining a signal transmission frequency of the signal transmitter;

In some embodiments, the signal strength value corresponding to the signal transmitter is processed according to a signal transmission frequency of the signal transmitter to obtain a target signal strength value, including:

Obtaining a weight value corresponding to a signal transmission frequency of the signal transmitter;

And weighting and summing the signal strength values corresponding to the signal transmitter 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.

In some embodiments, taking a signal strength value corresponding to the signal transmitter in a preset time period, including:

Obtaining a plurality of actual signal strength values corresponding to the signal transmitters in the preset time period;

Obtaining 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 a signal strength value corresponding to the signal transmitter.

In some embodiments, controlling the state of the display screen based on the target signal strength value and the signal strength threshold includes:

Obtaining a signal strength interval in which the target signal strength value is located;

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

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

In some embodiments, the signal strength threshold comprises a first threshold, and the step of controlling the state of the display screen according to the target signal strength value and the signal strength threshold comprises:

Determining whether the target signal strength value is greater than the first threshold when the display screen is in a bright screen state;

And if the target signal strength value is greater than the first threshold, controlling the display to be extinguished. According to the above description, in some embodiments, a display screen control method is also provided. Referring to FIG. 14, the specific process of the method is as follows:

S501. Acquire a signal strength value corresponding to the signal transmitter in the preset time period.

The signal strength value is a signal strength value of the detection signal detected by the signal receiver by the signal receiver.

For example, the signal strength corresponding to the signal transmitter is the strength of the detection signal emitted by the signal transmitter a detected by the signal receiver.

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

Taking three signal transmitters as an example, the signal strength value c1 corresponding to the signal transmitter a, the signal strength value c2 corresponding to the signal transmitter b2, and the signal strength value c3 corresponding to the signal transmitter c can be respectively obtained.

In some embodiments, multiple signal strength values corresponding to the signal transmitters, that is, multiple actual signal strengths, may be acquired within a preset time period. To facilitate control of the display state, the average signal strength corresponding to the signal transmitter may be calculated. The average signal strength is taken as the signal strength corresponding to the signal transmitter. For example, the step of “acquiring the signal strength value corresponding to the signal transmitter in the preset time period” may include:

For example, taking the signal transmitter a as an example, the signal transmitter a transmits the detection signal at regular intervals, and the signal receiver detects the detection signal transmitted by the signal transmitter a, so that a plurality of actual signals corresponding to the signal transmitter a can be obtained. The intensity values, such as n actual signal strength values c11, c12, ... c1n, n are positive integers greater than two. 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 signal strength corresponding to the signal transmitter a. The value c1.

S502. Acquire a signal transmission frequency of the signal transmitter.

The signal transmitting frequency of the signal transmitter is the number or the number of detecting signals transmitted by the signal transmitter in a unit time.

For example, the signal transmission frequency f1 of the signal transmitter a, the signal transmission frequency f2 of the signal transmitter b, and the signal transmission frequency f3 of the signal transmitter c can be obtained.

S503. Process a signal strength value corresponding to the signal transmitter according to a signal transmission frequency of the signal transmitter, to obtain a target signal strength value.

For example, based on the signal transmission frequency f1 of the signal transmitter a1, the signal transmission frequency f2 of the signal transmitter b2, the signal transmission frequency f3 of the signal transmitter c, the signal strength value c1 corresponding to the signal transmitter a1, and the 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 display state control, the signal strength value may be subjected to a weighted summation process, wherein the signal transmission frequency of the signal transmitter may correspond to the weight value. The step of “processing the signal strength value corresponding to the signal transmitter according to the signal transmission frequency of the signal transmitter to obtain the target signal strength value” may include:

For example, the weight value q1 corresponding to the signal transmission frequency f1 of the signal transmitter a1, the weight value q2 corresponding to the signal transmission frequency f2 of the signal transmitter b2, and the weight value q3 corresponding to the signal transmission frequency f3 of the signal transmitter c; The signal strength weighting sum is calculated as Q = c1 * q1 + c2 * q2 + c3 * q3; finally, the desired target signal strength value is obtained based on the signal strength weighted sum Q. For example, the signal strength can be weighted and Q to obtain the desired target signal strength value.

In some embodiments, the mapping relationship between the signal transmission frequency and the weight value may be preset, such that after acquiring the signal transmission frequency of the signal transmitter, the corresponding weight value may be acquired based on the mapping relationship.

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

Among them, the status of the display includes lighting and extinguishing.

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

In practical applications, the electronic device may control the state of the display screen according to the target signal strength value and the signal strength threshold according to the state of the display screen when it is required to control the state of the display screen. 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, the display can be turned off to prevent the user from causing a malfunction to the display. When the user's face is away from the display, the control display lights up to restore the normal display of the display.

In some embodiments, considering that the detection signal is attenuated during transmission, if the signal strength threshold is fixed, such as using a preset signal strength value, the proximity or distance determination may be inaccurate, thereby causing display. Screen state control is less accurate. Therefore, in order to improve the accuracy of the approach or the distance, the threshold may be varied based on the threshold subtraction coefficient corresponding to the current signal strength value to adapt to the proximity detection under the current signal strength value.

The step of “controlling the state of the display screen according to the target signal strength value and the signal strength threshold” may include:

The threshold attenuation coefficient is a attenuation ratio of the signal strength threshold, for example, may be 30 percent or the like.

For example, the signal intensity region (ci, cj) where the target signal strength value c is located is obtained, and the threshold attenuation coefficient corresponding to the signal strength region (ci, cj) is p, and the initial signal strength threshold is assumed to be y. The signal strength threshold Y = yy * p.

For example, if the target signal strength value obtained by the electronic device is 100, the signal strength interval in which the target signal strength value is located is (43, 159). Subsequently, the electronic device can obtain the signal intensity interval (43, 159) corresponding to The threshold attenuation coefficient is 30%. The initial signal strength threshold is 300. At this time, the signal strong threshold is 300-300*30%=210.

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

And if the target signal strength value is greater than the first threshold, controlling the display to be extinguished.

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

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

For example, if the first threshold is 243.9 and the second signal strength obtained by the terminal is 400, then the target signal strength value is greater than the first threshold, and the terminal controls the display to go out.

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 the off-screen state, determining whether the target signal strength value is less than a second threshold;

And if the target signal strength value is less than the second threshold, controlling the display to light.

Wherein, the signal strength threshold comprises a second threshold. The second threshold may be a low threshold. The low threshold is used to trigger the control display to illuminate when the display is in the off state. For the same electronic device in the same external environment, the low threshold is less than the high threshold described above.

After the display screen of the electronic device is in the off-screen state, after the electronic device acquires the target signal strength value, the electronic device compares the target signal strength value with the second threshold to determine whether the target signal strength value is smaller than the first Two thresholds. When it is determined that the target signal strength value is smaller than the second threshold, it indicates that the electronic device is in a distant state from an external object (for example, a user's face), and the control display is lit at this time. When it is determined that the target signal strength value is greater than or equal to the second threshold, it indicates that the electronic device is not in a distant state from an external object (for example, a user's face), and the electronic device maintains the display screen in a blank state. .

For example, if the second threshold is 200 and the target signal strength value obtained by the electronic device is 180, then the target signal strength value is less than the second threshold, and the electronic device controls the display to light.
