In some embodiments, please refer to fig. 8, and fig. 8 is a fifth structural diagram of an electronic device according to an embodiment of the present disclosure.

The electronic device includes two electrode assemblies 60, which are respectively disposed on the top of the electronic device. Specifically, the electrode body group 60 of the electronic device is provided on a top middle frame of the electronic apparatus, and the electronic device in fig. 6 can be realized by providing a multi-segment middle frame. For convenience of description, details of the electronic device may refer to those in fig. 6, and are not repeated herein.

The electronic device comprises two electronic devices, wherein a distance is arranged between the two electronic devices and is placed close to an earphone of the electronic device, and when a human face needs to use the earphone and is close to the electronic devices, the electric charges of equivalent capacitors formed by the electronic devices can be changed. By setting a distance between the electronic devices, it is possible to determine whether the human face is close or only the user touches by mistake by detecting the amount of change in the resulting electric charges for the two sets of electrode bodies 60.

For example, when the amount of change in charge of one of the electrode body groups 60 is large and larger than a preset value and the amount of change in charge of the other electrode body group 60 is small and smaller than the preset value, it may be determined that the detected object of the group having the large amount of change in charge is small, and the approaching object is not a human face and the electronic device does not respond thereto. When the charge variation of one of the electrode body groups 60 is larger than a preset value and the charge variation of the other electrode body group 60 is also larger than the preset value, it can be determined that the approaching object is likely to be a human face, and at this time, the electronic device performs corresponding operation when the human face approaches the approaching object. The specific value of the distance may be set according to actual conditions.

The arrangement mode of the two electrode body groups 60 in the electronic equipment can more accurately judge the position condition of the face when the face needs to use the receiver to be close to or far away from the electronic device, and can effectively avoid misjudgment generated when other objects are close to or far away from the electronic device.

For convenience of description, details of the electronic device may refer to those in fig. 6, and are not repeated herein.

Similarly, the two sets of electrode assemblies 60 in the electronic device can be arranged in a manner that the position of the human face can be more accurately determined when the human face needs to use the receiver to approach or leave the electronic device, and the erroneous determination caused by approaching or leaving other objects can be effectively avoided.

In some embodiments, please refer to fig. 10, where fig. 10 is a schematic diagram illustrating a seventh structure of an electronic device according to an embodiment of the present disclosure.

Compared with fig. 8 or 9, this embodiment is different in that the electronic device includes two sets of electrode body groups 60, and is respectively provided behind the display screen 40 of the electronic apparatus, that is, on the other side of the display screen 40 with respect to the display direction.

Of course, the same can be placed near the receiver of the electronic device, so that when a human face needs to use the receiver to be close to the electronic device, the more reliable charge variation can be detected.

In some embodiments, please refer to fig. 11, and fig. 11 is an eighth structural schematic diagram of an electronic device according to an embodiment of the present application.

For example, when the electronic device detects that a human body approaches, the detecting chip 603 sends an electrical signal corresponding to the approach of the human body, and the processor 31 performs a screen-off operation on the display screen 40 according to the electrical signal.

Or, when the electronic device detects that the human body is far away, and the display screen 40 is in a screen-off state that the human body enters after approaching, the detection chip 603 sends a corresponding electric signal when the human body is far away, and the processor 31 performs a screen-on operation on the display screen 40 according to the electric signal.

This electronic equipment can be through the equivalent capacitance that sensing structure formed, and whether can confirm the object and be approaching according to the capacitance change when the object is close, need not to set up alone and is close the condition that approaches that sensing assembly comes perception object, need not trompil on electronic equipment's panel, and then reduce electronic equipment's manufacturing cost.

In some embodiments, please refer to fig. 12, and fig. 12 is a flow chart illustrating an implementation of a display screen control method according to an embodiment of the present disclosure.

The display screen control method can be applied to the electronic equipment with the electronic device, which is described in fig. 1-11, and the method comprises the following steps:

201. and acquiring a first charge variation of the first electrode body group and a second charge variation of the second electrode group.

When a human body part approaches the electronic device, the equivalent capacitance formed by the electrode body group can change the charge quantity under the influence of the human body part. Therefore, the first charge variation of the first electrode group and the second charge variation of the second electrode group are obtained, and whether the human body part approaches can be judged according to the charge variations of the two positions.

Specifically, the measurement can be performed by a detection chip in the electronic device, the detection chip can be of a type that can be used in the prior art, and the connection relationship between the detection chip and the first electrode body and the connection relationship between the detection chip and the second electrode body can be set according to actual conditions. For example, the detection end of the detection chip is connected between the first electrode body and the second electrode body, or the detection chip can form a coupling relationship with an equivalent capacitor formed between the first electrode body and the second electrode body through other connection methods, and at this time, a change in charge generated between the first electrode body and the second electrode body can be detected through the detection chip.

202. And determining whether a target object is close to or far away from the electronic equipment in the detection range according to the first charge variation and the second charge variation, and obtaining a determination result.

The target object is mainly a human body part, such as a human face.

When the first charge variation and the second charge variation are obtained, whether a face is close to or away from the face can be judged according to the relationship between the first charge variation and the second charge variation.

The determining process may be to determine the magnitude of the charge variation of the two electrode body groups, or to determine the magnitude relationship between the charge variations of the two electrode body groups.

For example, whether the values of the first charge variation and the second charge variation are larger than a preset value or not is determined respectively, or whether the human face or only the finger with a larger area is determined by combining the difference between the values of the first charge variation and the second charge variation.

203. And controlling the on-off of the display screen according to the determined result.

For example, when the charge variation of one of the electrode body groups is larger than a preset value and the charge variation of the other electrode body group is smaller than the preset value due to the larger area of the human face, it may be determined that the detected object of the group with the larger charge variation is smaller, the approaching object is not a human face, and the electronic device does not respond thereto. When the charge variation of one electrode body group is larger than a preset value, and the charge variation of the other electrode body group is also larger than the preset value, it can be determined that the approaching object is likely to be a human face, and at the moment, the electronic device performs corresponding operation when the human face approaches the approaching object. The specific value of the distance may be set according to actual conditions.

It should be noted that, in the embodiment of the present application, only a detection and determination manner between two sets of electrode body groups is provided, and similarly, the detection and determination manner can be applied as a unit to an electronic device having more than two sets of electrode body groups and an electronic apparatus having the structure, and details of the detection and determination manner are not repeated herein.

When the electronic device detects that a human body is close to, the detection chip can send an electric signal corresponding to the human body when the human body is close to, and the processor of the electronic equipment can perform screen extinguishing operation on the display screen according to the electric signal.

Or, when the electronic device detects that the human body is far away from, and the display screen is in the screen extinguishing state that just gets into after being close to because of the human body this moment, detect the signal of telecommunication that corresponds when the chip can send the human body to keep away from this moment, the treater can carry out the bright screen operation to the display screen according to this signal of telecommunication.

Therefore, the display screen control method can judge the situation of an object close to or far away from the electronic equipment by acquiring the charge variation of the two groups of electrode bodies and according to the two groups of charge variation, can judge the position situation of the face more accurately when the face needs to use the receiver and is close to or far away from the electronic device, does not need to separately set a proximity sensing component to sense the approaching situation of the object, does not need to open holes on a panel of the electronic equipment, further reduces the manufacturing cost of the electronic equipment, and effectively avoids misjudgment generated when other objects are close to or far away.

In some embodiments, please refer to fig. 13, and fig. 13 is an implementation flow for determining whether a target object is close to or far away according to the embodiment of the present disclosure. The process comprises the following steps:

301. and when the first charge variation and the second charge variation are both larger than a preset value, acquiring a difference value of the two groups of charge variations.

In order to reduce the erroneous determination, the triggering limitation may be performed by setting a lowest charge variation as a threshold, that is, the preset value, and the action may be triggered only when both the first charge variation and the second charge variation are greater than the preset value.

Then, after the first charge variation and the second charge variation are both larger than the preset value and the judging step is triggered, the difference of the numerical value variation amplitude of the two groups of charge variations can be determined by obtaining the difference value of the two groups of charge variations.

302. And determining whether a target object is close to or far away from the electronic equipment in the detection range according to the difference value to obtain a determination result.

The area of the object close to or far away from the electronic equipment can be determined according to the difference value, and therefore mistaken touch is avoided.

Specifically, the method may include:

judging whether the difference value is smaller than a preset threshold value or not;

if yes, determining that the target object is close to or far away from the electronic equipment in the detection range;

and if not, determining that no target object is close to or far away from the electronic equipment in the detection range.

For example, when a finger is close to an electronic device having two sets of electrode body groups and is closer to one of the electrode body groups, the amount of charge change detected by the electrode body group closer to the finger is larger, and the amount of charge change of the other electrode body group is smaller due to the distance relationship, a human body part with a smaller volume can be easily determined, such as the finger. On the contrary, if the difference of the charge variation of the two electrode body groups is small, a human body part with a large volume, such as a human face, can be determined. Therefore, the judgment result is more accurate under the condition that the operation is only executed when the human face is close to or far away from the human face.

Therefore, when the first charge variation and the second charge variation are both larger than the preset value, the difference value of the two sets of charge variations is obtained, whether the target object is close to or far away from the electronic equipment is judged by utilizing the difference value, the condition of mistaken touch or misjudgment can be effectively avoided, and the judgment result is more accurate and reliable.
