As shown in fig. 1, fig. 1 is a flowchart illustrating a screen control method according to an exemplary embodiment, which may be used in an electronic device, and includes the following steps 101 to 103:

in step 101, when a hall potential change is detected by a hall sensor on an electronic device, it is determined whether the environment in which the electronic device is located is interfered by an interference magnetic field.

In step 102, when it is determined that the environment where the electronic device is located is interfered by an interference magnetic field, detecting a distance of a protective case worn by the electronic device relative to a screen of the electronic device through a distance sensor.

In step 103, it is determined whether to trigger a screen-on event or a screen-off event according to the detected distance, where the screen-on event is an event of lighting up a screen of the electronic device, and the screen-off event is an event of turning off the screen of the electronic device.

In the embodiment of the present disclosure, the electronic device may be an electronic product provided with a hall sensor, such as a smart phone, a tablet computer, a PDA (Personal digital assistant), an e-book reader, and a multimedia player. To protect the electronic device from damage, the electronic device may be provided with a protective case. The protective sleeve may include a movable component and a stationary component. The movable component, which may also be referred to as a protective cover, is a movably operable component. A magnet may be mounted on the movable component of the protective cover to cause a change in hall potential in the hall sensor during opening or closing of the protective cover.

The Hall sensor can be arranged on a mainboard of the electronic equipment, when the movable assembly on the protective sleeve is opened or closed, the Hall sensor can detect that Hall potential changes, and the electronic equipment can judge whether the protective sleeve is opened or closed according to the output result of the Hall sensor.

The distance sensor is used for detecting the distance between the movable component on the protective sleeve and the screen of the electronic equipment. The distance sensor may be a distance sensor that detects a distance by infrared emission, a distance sensor that detects a distance by ultrasonic waves, or the like. The distance sensor may be provided on the electronic device or on a fixed part of the protective cover. When the distance sensor is arranged on the electronic equipment, the arranged position is the position capable of detecting the distance between the movable assembly on the protective sleeve and the screen of the electronic equipment, and the movable assembly of the protective sleeve can be judged to be in a state of being far away from the screen or a state of being close to the screen according to the distance between the movable assembly and the screen of the electronic equipment. If the distance sensor is arranged on the fixing part of the protective sleeve, the distance sensor is connected with the electronic equipment in a wired or wireless mode, so that the electronic equipment can acquire the distance detected by the distance sensor, and can judge whether the movable assembly of the protective sleeve is in a state of being far away from the screen or a state of being close to the screen according to the acquired distance.

Because when the protective sheath that electronic equipment dressed is opened or closed, or receive external interference magnetic field interference, hall sensor on the electronic equipment all can detect hall electric potential and change, consequently only confirm whether trigger the bright screen event or go out the screen event through the data of hall sensor output, can lead to the erroneous judgement. Therefore, the Hall sensor and the distance sensor are combined for judgment, misjudgment can be avoided, and then a screen-on event or a screen-off event is prevented from being triggered by mistake.

The interference magnetic field is a magnetic field except a normal magnetic field such as a geomagnetic field and a magnetic field generated by a magnet on a protective sleeve worn by the electronic equipment, and whether the protective sleeve is opened or closed cannot be correctly judged only according to data output by the Hall sensor under the interference of the interference magnetic field. Therefore, when the Hall sensor on the electronic equipment detects the change of the Hall potential, whether the environment where the electronic equipment is located is interfered by an interference magnetic field or not is judged, and when the environment where the electronic equipment is located is determined to be interfered by the interference magnetic field, the distance of the protective sleeve worn by the electronic equipment relative to the screen of the electronic equipment is detected through the distance sensor. The distance of the protective case relative to the screen of the electronic device is the distance of the movable component of the protective case relative to the screen of the electronic device. By acquiring the distance, whether the movable assembly of the protective sleeve is in a state far away from the screen or in a state close to the screen can be judged, so that whether a screen-on event or a screen-off event is triggered or not is determined. Specifically, if the movable assembly of the protective sleeve is determined to be in a state far away from the screen according to the detected distance, a screen-on event is triggered, and if the movable assembly of the protective sleeve is determined to be in a state close to the screen according to the detected distance, a screen-off event is triggered.

In an optional implementation manner, when it is determined that the environment where the electronic device is located is not interfered by the interference magnetic field, whether a screen-on event or a screen-off event is triggered can be judged according to the output result of the hall sensor.

Therefore, when it is determined that the environment where the electronic device is located is not interfered by the interference magnetic field, the output result of the hall sensor can be used for judging whether to trigger a screen-on event or a screen-off event, so that the method is easy to implement, and can avoid misjudgment caused by judging only by the distance sensor under any condition.

In another alternative implementation manner, when it is determined that the environment where the electronic device is located is not interfered by the interference magnetic field, whether a screen-on event or a screen-off event is triggered is determined simultaneously according to the output result of the hall sensor and the detected distance.

According to the embodiment, whether the screen-on event or the screen-off event is triggered or not can be judged simultaneously through the output result and the detected distance of the Hall sensor, the event is triggered when the same event is judged to be triggered according to the output result and the detected distance, and otherwise, the event is not processed.

Therefore, when it is determined that the environment where the electronic device is located is not interfered by the interference magnetic field, whether the screen-on event or the screen-off event is triggered or not can be judged simultaneously through the output result of the hall sensor and the detected distance, so that the judgment accuracy is improved, the user experience is improved, and the trouble brought to the user by misjudgment is avoided.

It can be seen from the above embodiments that, according to the present disclosure, when detecting a change in hall potential through a hall sensor on an electronic device, it is determined whether an environment in which the electronic device is located is interfered by an interference magnetic field, when it is determined that the environment in which the electronic device is located is interfered by the interference magnetic field, a distance of a protective cover worn by the electronic device with respect to a screen of the electronic device is detected through a distance sensor, and whether a screen-on event or a screen-off event is triggered is determined according to the detected distance. Through combining hall sensor and distance sensor to can avoid only judging the erroneous judgement that leads to through hall sensor's output result when receiving interference magnetic field interference, and then avoid the erroneous judgement to bring not good user experience for the user.

There are many ways to determine whether the environment of the electronic device is interfered by the interference magnetic field, and several ways are listed below for description.

In an optional implementation manner, when the interference instruction is received, whether the environment where the electronic equipment is located is interfered by an interference magnetic field or not is judged. The interference instruction may be an instruction generated by triggering by the user through a triggering key or a button, and the interference instruction indicates that the current environment is interfered by the interference magnetic field.

Therefore, the judgment of the interference magnetic field is realized in an interference instruction mode, and the judgment is easy to realize.

In another optional implementation manner, whether the environment where the electronic device is located is interfered by an interference magnetic field is determined according to the magnetic field intensity detected by a magnetic field sensor arranged on the protective sleeve, wherein the relative position of the magnetic field sensor and a magnet on the protective sleeve is fixed in the process of closing or opening the protective sleeve.

In this embodiment, the magnetic field sensor may be disposed on the protective cover, and the relative position between the magnetic field sensor and the magnet on the protective cover is fixed, so that the magnetic field strength detected by the magnetic field sensor is not affected by the closing process and the opening process of the protective cover, i.e. the magnetic field strength detected by the magnetic field sensor during the closing process and the opening process of the protective cover is the same or within a range of magnetic field strengths with little difference.

In one example, a threshold range of magnetic field strength can be set based on the strength of the magnetic field detected by the magnetic field sensor during closure and opening of the protective sleeve. If the magnetic field intensity detected by the magnetic field sensor is within the magnetic field intensity threshold range, determining that the environment where the electronic equipment is located is not interfered by an interference magnetic field; and if the magnetic field intensity detected by the magnetic field sensor is not within the range of the magnetic field intensity threshold value, determining that the environment where the electronic equipment is located is interfered by the interference magnetic field.

In addition, since the magnetic field sensor is disposed on the protective cover, in order to obtain the magnetic field intensity from the magnetic field sensor disposed on the protective cover, the electronic device may be connected to the magnetic field sensor in a wired or wireless manner so as to obtain the magnetic field intensity detected by the magnetic field sensor.

Therefore, in the embodiment, the magnetic field intensity can be acquired from the magnetic field sensor arranged on the protective sleeve, and whether the environment where the electronic equipment is located is interfered by the interference magnetic field is judged through the acquired magnetic field intensity, so that whether the electronic equipment is interfered by the interference magnetic field is automatically judged, and manual participation is not needed.

In another alternative implementation manner, a magnetic field strength value and/or a magnetic field strength direction may be obtained from a magnetic field sensor disposed on the electronic device, and whether the environment where the electronic device is located is interfered by the disturbing magnetic field may be determined according to the obtained magnetic field strength value and/or magnetic field strength direction. As shown in fig. 2, fig. 2 is a flowchart illustrating another screen control method according to an exemplary embodiment of the present disclosure, which may be used in an electronic device, and the method includes the following steps 201 to 204:

in step 201, when a hall potential change is detected by a hall sensor on the electronic device, a magnetic field strength value and/or a magnetic field strength direction is obtained from a magnetic field sensor provided on the electronic device.

In step 202, it is determined whether the environment where the electronic device is located is interfered by an interfering magnetic field according to the obtained magnetic field strength value and/or magnetic field strength direction.

In step 203, when it is determined that the environment where the electronic device is located is interfered by an interference magnetic field, detecting a distance of a protective case worn by the electronic device relative to a screen of the electronic device through a distance sensor.

In step 204, it is determined whether to trigger a screen-on event or a screen-off event according to the detected distance, where the screen-on event is an event of lighting up a screen of the electronic device, and the screen-off event is an event of turning off the screen of the electronic device.

In this embodiment, since the magnetic field sensor is provided on the electronic device, the magnetic field strength detected by the magnetic field sensor is affected by the opening and closing processes of the protective cover. When the hall potential change is detected by the hall sensor on the electronic device, the magnetic field strength value and/or the magnetic field strength direction detected by the magnetic field sensor provided on the electronic device can be acquired.

Aiming at the magnetic field intensity direction, the magnetic field intensity directions in the opening process and the closing process of the protective sleeve can be collected under the condition that an interference magnetic field does not exist, and a preset magnetic field intensity direction is obtained. If the obtained magnetic field intensity direction is different from the preset magnetic field intensity direction in the process that the Hall sensor detects that the Hall potential changes, it is judged that the environment where the electronic equipment is located is interfered by the interference magnetic field, and the preset magnetic field intensity direction is the magnetic field direction detected by the magnetic field sensor under the influence of the interference magnetic field. The magnetic field sensor can detect the directions of the three-axis magnetic field, and if one of the detected directions of the three-axis magnetic field is different from the preset magnetic field strength direction, the electronic equipment can be judged to be interfered by an interference magnetic field in the environment.

Therefore, whether the environment where the electronic equipment is located is interfered by the interference magnetic field or not is judged according to the magnetic field intensity direction, and the method is easy to realize.

And when the acquired magnetic field strength value is larger than a preset magnetic field strength threshold value according to the magnetic field strength value, judging that the environment where the electronic equipment is located is interfered by an interference magnetic field.

In this embodiment, a threshold magnetic field strength value may be preset, where the threshold magnetic field strength value is greater than the magnetic field strength value detected by the magnetic field sensor under the influence of the interference magnetic field. Therefore, when the obtained magnetic field strength value is larger than the preset magnetic field strength threshold value, the environment where the electronic equipment is located can be judged to be interfered by the interference magnetic field.

In one example, the predetermined threshold magnetic field strength value is determined from a maximum magnetic field strength value that is a magnetic field strength value that the magnetic field sensor detects when the protective casing is in the closed state when not under the influence of an interfering magnetic field.

When the protective cover is closed without being affected by the disturbing magnetic field, the magnetic field intensity detected by the magnetic field sensor is maximum, and this intensity value can be determined as the maximum magnetic field intensity value.

In one aspect, the preset magnetic field strength threshold may be the same as the maximum magnetic field strength value. And at the moment, when the acquired magnetic field strength value is greater than the maximum magnetic field strength value, judging that the environment where the electronic equipment is located is interfered by the interference magnetic field.

On the other hand, the preset magnetic field strength threshold value may be a value slightly larger or smaller than the maximum magnetic field strength value in order to avoid an influence caused by a detection error. Since the preset magnetic field intensity threshold is slightly larger or smaller than the maximum magnetic field intensity value, erroneous judgment caused by detection errors can be avoided.

In another example, in some cases, although the interference magnetic field is interfered, if the interference magnetic field is not large enough to affect the output result of the hall sensor, the output result of the hall sensor may still be used to determine whether to trigger the screen-on event, based on which the preset threshold of the magnetic field strength is determined according to the threshold of the magnetic field strength, which is the strength of the magnetic field strength detected by the magnetic field sensor when the hall sensor triggers the screen-on event/the screen-off event without being influenced by the interference magnetic field.

Because the Hall sensor outputs the output result which can trigger the screen-on event/screen-off event when detecting that the Hall potential changes to the critical value, the magnetic field intensity critical value detected by the magnetic field sensor is obtained when the Hall potential reaches the critical value. For example, the hall sensor outputs 1 when detecting that the hall potential changes to the first critical value, and 1 may indicate that a screen-lighting event is triggered, and a first magnetic field strength critical value detected by the magnetic field sensor when the hall potential changes to the first critical value is obtained; the Hall sensor outputs 0 when detecting that the Hall electric potential changes to a second critical value, wherein 0 can indicate that a screen-off event is triggered, and the second magnetic field intensity critical value detected by the magnetic field sensor when the Hall electric potential changes to the second critical value is obtained. The first critical value and the second critical value may be the same or different, and are specifically set according to requirements.

In an optional implementation manner, the preset magnetic field strength threshold is determined according to a sum of a maximum magnetic field strength value and a first magnetic field strength critical value, where the maximum magnetic field strength value is a magnetic field strength value detected by the magnetic field sensor in the closed state of the protective sleeve under the influence of an interference magnetic field, and the first magnetic field strength critical value is a magnetic field strength value detected by the magnetic field sensor when the hall sensor triggers a screen-on event under the influence of the interference magnetic field.

As one of the abnormal conditions, the screen is not lighted when the protective cover is opened, which may be because the hall potential cannot reach the first threshold value, there may be a magnetic field strength which is in the same direction as the first magnetic field strength threshold value and is greater than or equal to the first magnetic field strength threshold value. Therefore, the preset magnetic field strength threshold value may be a value greater than or equal to the sum value or a value slightly smaller than the sum value. The sum is the sum of a maximum magnetic field strength value and a first magnetic field strength critical value, the maximum magnetic field strength value is the magnetic field strength value detected by the magnetic field sensor when the protective sleeve is in the closed state under the influence of an interference magnetic field, and the first magnetic field strength critical value is the magnetic field strength value detected by the magnetic field sensor when the Hall sensor triggers a screen-lighting event under the influence of the interference magnetic field.

Based on the method, the maximum value monitored by the magnetic field sensor in the opening process can be obtained from the magnetic field sensor arranged on the electronic equipment, and when the obtained maximum value is larger than the preset magnetic field intensity threshold value, the environment where the electronic equipment is located is judged to be interfered by the interference magnetic field. This embodiment can avoid an abnormal situation where the protective cover is opened without lighting the screen.

In another optional implementation manner, the preset magnetic field strength threshold is determined according to a second magnetic field strength critical value, the direction of the preset magnetic field strength is opposite to that of the second magnetic field strength critical value, and the second magnetic field strength critical value is a magnetic field strength value detected by the magnetic field sensor when the hall sensor triggers a screen-out event under the influence of an undisturbed magnetic field.

As one of the abnormal conditions, the protective cover is closed without shielding, which may be because the hall potential cannot reach the second threshold, and there may be a magnetic field strength opposite to the second threshold and greater than or equal to the second threshold. Thus, the preset magnetic field strength threshold value may be a value greater than or equal to the second magnetic field strength threshold value, or a value slightly less than the second magnetic field strength threshold value.

Based on the method, a magnetic field strength value and a magnetic field strength direction are obtained from a magnetic field sensor arranged on the electronic equipment, and when the obtained magnetic field strength is larger than or equal to a preset magnetic field strength threshold value and the obtained magnetic field strength direction is opposite to the direction of a second magnetic field strength critical value, the environment where the electronic equipment is located is judged to be interfered by an interference magnetic field. This embodiment can avoid closed protective sheath but not extinguish the abnormal conditions of screen, and then avoids the electric quantity waste that the bright screen leads to.

Therefore, whether the environment where the electronic equipment is located is interfered by the interference magnetic field can be judged alone according to the magnetic field strength value or the magnetic field strength direction, and whether the environment where the electronic equipment is located is interfered by the interference magnetic field can also be judged by combining the magnetic field strength value and the magnetic field strength direction.

In addition, the synchronization steps 102 and 103 in

steps
