[0059] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0060] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” used herein refers to and includes any and all possible combinations of one or more of the associated listed items.
[0061] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if," as used herein, may be interpreted as "when," "when," or "in response to determination."
[0062] After configuring a protective cover, the user wants to control the screen's on / off state by moving the cover closer to or further away from the screen. A Hall sensor can be pre-installed on the terminal screen; by default, the Hall sensor uses an edge-triggered interrupt mode to trigger event processing.
[0063] Edge-triggered methods, for example Figure 1 As shown, in a Hall sensor, electrons in the vertical direction generate a transverse potential difference under the influence of the Lorentz force of a magnetic field, and the voltage changes with the magnetic field strength. The switch-type Hall sensor sets two threshold values, B1 and B2, based on the change in the magnetic field. When the magnetic field strength is greater than B2, a corresponding voltage level is generated. When the magnetic field strength is less than B1, a corresponding voltage level is generated. When the magnetic field strength is between B1 and B2, the voltage level remains unchanged.
[0064] When a magnet is placed inside the protective cover, and the cover is closed, the magnet approaches the Hall sensor, at which point the magnetic field strength reaches B2. The Hall sensor uses edge triggering as its interrupt triggering method; at the instant the voltage level changes, the Hall sensor reports the corresponding event and triggers screen off.
[0065] When the cover is opened, the magnet inside the cover moves away from the Hall sensor. When the magnet moves away from the Hall sensor to a certain position, the magnetic field strength decreases to B1, and the corresponding level value also changes, triggering the screen to light up.
[0066] However, because edge-triggered sensors are easily disturbed by electromagnetic interference, Hall sensors are prone to misjudgment due to other electromagnetic interference in the terminal environment, resulting in incorrect screen lighting or turning off.
[0067] To address the aforementioned problems, this disclosure provides a screen state switching method that can be used in terminals such as smartphones, tablets, and personal digital assistants (PDAs). Figure 2 As shown, Figure 2 This is a screen state switching method according to an exemplary embodiment, comprising the following steps:
[0068] In step 101, it is determined whether the level value generated by the target sensor has changed.
[0069] In this embodiment of the disclosure, the target sensor may be a Hall sensor mounted on the terminal screen. The target sensor determines whether the corresponding generated voltage level has changed based on the magnetic field strength. For example, the voltage level was previously low and the changed voltage level is high, or the voltage level was previously high and the changed voltage level is low.
[0070] In step 102, if the level value changes, the screen state is switched.
[0071] In this embodiment of the disclosure, after determining that the level value generated by the target sensor has changed, the screen state can be switched to the corresponding target screen state according to the changed target level value.
[0072] In the above embodiments, a level-triggered method is adopted to switch the screen state after the level value of the target sensor changes. This avoids misjudgment caused by electromagnetic interference from the surrounding environment when the target sensor uses an edge-triggered method, thus improving the accuracy of screen state switching and increasing its usability.
[0073] In an alternative embodiment, such as Figure 3 As shown, Figure 3 In the aforementioned Figure 2Based on the illustrated embodiment, another screen state switching method is shown, which may further include:
[0074] In step 103, multiple newly generated level values of the target sensor are continuously determined.
[0075] In this embodiment of the disclosure, the number of multiple level values can be a preset number. For example, the preset number is 5. After the terminal determines that the level value has changed, it can determine 5 new level values generated by the target sensor 5 times consecutively.
[0076] In step 104, based on the target level value changed by the target sensor and the plurality of level values, it is determined whether the screen state needs to be switched.
[0077] In this embodiment of the disclosure, if multiple consecutively determined level values are the same and all are the target level value, it is determined that the screen state needs to be switched; otherwise, it is determined that the screen state does not need to be switched. The target level value is the level value after the target sensor has changed.
[0078] After determining that the screen state needs to be switched, step 102 is executed to switch the screen state.
[0079] In the above embodiments, after the level value of the target sensor changes, multiple newly generated level values of the target sensor can be continuously determined. If the multiple level values are the same and the same as the target level value, it is determined that the screen state needs to be switched; otherwise, it is determined that the screen state does not need to be switched. This further reduces the possibility of false judgments from the target sensor, improves the accuracy of screen state switching, and has high usability.
[0080] In an alternative embodiment, such as Figure 4 As shown, Figure 4 In the aforementioned Figure 2 Based on the illustrated embodiment, another screen state switching method is shown, which may further include:
[0081] In step 105, the target event corresponding to the target level value after the target sensor changes is determined according to the preset correspondence between the level value and the event.
[0082] In this embodiment of the disclosure, the target level value is the level value changed by the target sensor, and the target event may include the target object moving away from the screen or the target object moving closer to the screen. Here, the target object may refer to the protective cover of the terminal.
[0083] Optionally, after the target sensor's voltage level changes to the target voltage level, the corresponding target event can be determined based on a preset correspondence between voltage level and events. Alternatively, after the target sensor's voltage level changes to the target voltage level, multiple newly generated voltage levels from the target sensor can be determined consecutively. If multiple voltage levels are identical to the target voltage level, the target event corresponding to the target voltage level can be determined based on the preset correspondence between voltage level and events.
[0084] For example, when the target level is high, the corresponding target event is that the target object is approaching the screen; when the target level is low, the corresponding target event is that the target object is moving away from the screen.
[0085] In step 106, the target event is reported through the target sensor.
[0086] The target sensor can report identified target events to the terminal's central processing unit.
[0087] Accordingly, step 102 may include:
[0088] In step 102-1, based on the preset correspondence between events and screen states, the screen state corresponding to the reported target event is taken as the target screen state.
[0089] For example, if the target event is that the target object approaches the screen, the target screen state is off. If the target event is that the target object moves away from the screen, the target screen state is on.
[0090] In step 102-2, the screen state is switched to the target screen state.
[0091] In this embodiment of the disclosure, the terminal's central processing unit can directly switch the screen state to the target screen state.
[0092] In the above embodiments, the target event corresponding to the target level value can be determined based on the correspondence between the level value and the event, and the target sensor reports the target event. Subsequently, based on the correspondence between the event and the screen state, the screen state is switched to the target screen state corresponding to the reported target event, which is simple to implement and highly usable.

The target event includes the target object moving away from the screen or the target object moving closer to the screen. The target sensor reports the target event to the central processing unit. The switching of the screen state includes: Based on the preset correspondence between events and screen states, the screen state corresponding to the reported target event is taken as the target screen state. The central processing unit switches the screen state to the target screen state.
