Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The technical scheme of the exemplary embodiment of the present disclosure may be applied to a terminal including a folding screen, and determine an application scene displayed by each of the folding screens of the terminal at the time of booting. In the exemplary embodiments described below, a terminal is sometimes also referred to as an intelligent terminal device, where the terminal may be a Mobile terminal, and may also be referred to as a User Equipment (UE), a Mobile Station (MS), and the like. A terminal is a device that provides voice and/or data connection to a user, or a chip disposed in the device, such as a handheld device, a vehicle-mounted device, etc. having a wireless connection function. Examples of terminals may include, for example: the Mobile terminal comprises a Mobile phone, a tablet computer, a notebook computer, a palm computer, Mobile Internet Devices (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote operation, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home and the like.
At present, a terminal including a folding screen has become a trend of the terminal. When a terminal including a folding screen operates, the attitude of the terminal is generally obtained according to a gyroscope sensor configured in the terminal, and then the content to be displayed on each screen in the folding screen is determined according to the attitude of the terminal.
However, at the moment of starting up the terminal, since the terminal operating system is not completely started, the module for controlling the display function in the terminal cannot work, and thus the present disclosure provides a terminal including a main screen, an auxiliary screen, a hall sensor, and a magnet. Wherein: the main screen is a folding screen, and the folding screen is folded along the bending area to form at least a first screen and a second screen; the auxiliary screen and the main screen deviate from each other; the Hall sensor is installed in the preset position of the first screen, and the magnet is installed in the second screen. The terminal that this disclosure provided, hall sensor and magnet based on in installation, in the start in the twinkling of an eye, through the output level that relies on hall sensor when the start, the perception start folding screen is located in the twinkling of an eye whether the state is expanded, still fold condition to according to folding screen state, control folding screen shows.
Fig. 1 is a schematic diagram of a trigger condition of the output level of the hall sensor. In fig. 1, Bnp represents the magnetic induction at the "on" threshold point, and BRP represents the magnetic induction at the "off" threshold point. When the applied magnetic induction exceeds the action point Bnp, the sensor outputs a low level, and when the magnetic induction drops below the threshold point Bnp, the sensor output level is unchanged, and the sensor jumps from the low level to the high level until the magnetic induction drops below the threshold BRP. Therefore, when the distance between the Hall sensor and the magnet is very close, the magnetic field intensity detected by the Hall sensor triggers the Hall sensor to output a low level, and when the distance between the Hall sensor and the magnet is very far, the magnetic field intensity detected by the Hall sensor triggers the Hall sensor to output a high level.
Fig. 2 is a schematic diagram showing the magnetic field intensity distribution of the magnet. In FIG. 2, let B be the magnetic flux density, ds be the unit area, and the magnetic flux be
Then the following formula:
it can be seen that the magnetic field of the magnet is most intense and concentrated at four positions shown in the N-and S-levels, and is most weak and discrete in the region between the N-and S-levels.
Furthermore, after the main screen is folded, if the hall sensor is located in the middle region of the magnetic field, that is, in the magnetic field region other than the 4 positions in fig. 2, since the magnetic property is weakest and discrete in the middle region between the N-level and the S-level, even if the main screen is folded, the hall sensor and the magnet are located very close to each other, the hall sensor may not detect a large change in the magnetic field, that is, the hall sensor may not be located in the middle region between the N-level and the S-level of the magnet.
In order to ensure that when the main screen is folded and unfolded, the magnetic field change reaches the triggering threshold of the Hall sensor, so that the output level of the Hall sensor is converted into high and low levels, when the main screen is folded, the preset position of the Hall sensor is met, the Hall sensor is positioned on one side of the direction of the first magnetic pole of the magnet, the first magnetic pole can be N-level or S-level, and the distance between the Hall sensor and the first magnetic pole is smaller than the set distance threshold. I.e. the hall sensors are at four positions of the magnet in fig. 2 when the main screen is in the folded state.
Fig. 3-5 are top views showing the position of the hall sensor and magnet after the main screen is folded according to an exemplary embodiment. In fig. 3, after the main screen is folded, from the top view, the hall sensor is located on one side of the direction of the N magnetic pole of the magnet, and is next to the N level, that is, the distance from the N magnetic pole is smaller than the set distance threshold. In fig. 4, the hall sensor is located on one side of the direction of the S-pole of the magnet, and the distance from the S-pole is smaller than the set distance threshold. In fig. 5, after the main screen is folded, from the top view, the hall sensor is located on one side of the direction of the N magnetic pole of the magnet, and is next to the N level, that is, the distance from the N magnetic pole is smaller than the set distance threshold.
Therefore, when the main screen is in a folded state, the distance between the Hall sensor and the first magnetic pole of the magnet is relatively short and is positioned at 4 positions shown in figure 2, and the Hall sensor detects the intensity of the magnetic field and outputs low level. When the main screen is in an unfolded state, the distance between the Hall sensor and the first magnetic pole of the magnet is very short, and the Hall sensor detects that the magnetic field is weak and outputs high level.
FIG. 6 is an exemplary diagram illustrating the position of a Hall sensor and magnet after the main screen is unfolded, according to one exemplary embodiment. In fig. 6, the main panel is a folded panel, which along the bending area may be folded to form, for example, a left panel, i.e. a first panel, and a right panel, i.e. a second panel. The hall sensor and the magnet may be mounted, for example, at the illustrated positions of the first screen and the second screen, respectively.

In fig. 7, the main screen is a folded screen, the folded screen includes a first bending region and a second bending region, and the folded screen is folded along the first bending region to form a first screen and a second screen. The hall sensor and the magnet may be mounted, for example, at the illustrated positions of the first screen and the second screen, respectively.

In fig. 8, the main screen is a folded screen, the folded screen includes a first bending region and a second bending region, and the folded screen is folded along the second bending region to form the first screen and the second screen. The hall sensor and the magnet may be mounted, for example, at the illustrated positions of the first screen and the second screen, respectively.

The hall sensor and the magnet may be mounted, for example, at the illustrated positions of the first screen and the second screen, respectively.
For example, fig. 10 to 12 of the present disclosure take a terminal main screen as a foldable screen including a bendable region, and the foldable screen can be folded along the bendable region to form a first screen and a second screen, as an example, a terminal display interface of the terminal main screen in different states is described.

In fig. 10, when the main screen is in a fully unfolded state, that is, an included angle between the first screen and the second screen is 180 °, at the instant of power-on start of the terminal, the main screen is determined to be in an unfolded state according to a high level output by the hall sensor, the main screen is controlled to display, and the auxiliary screen is kept in a screen-off state.

In addition, when the terminal main screen is a folding screen including two folding areas, and the folding screen is folded along one bending area to form two screens, the terminal display interface may be displayed in the following manner, for example, according to different states of the terminal main screen:
for example, for the main screen shown in fig. 7 and 8, when the main screen is in a fully unfolded state, that is, an included angle between the first screen and the second screen is 180 °, and an included angle between the second screen and the third screen is also 180 °, at the instant of power-on start of the terminal, the main screen is determined to be in an unfolded state according to a high level output by the hall sensor, the main screen, that is, the first screen, the second screen, and the third screen are controlled to display, and the auxiliary screen is kept in a screen-off state.
When the main screen is in a partially unfolded state, namely an included angle between the first screen and the second screen is larger than a preset angle, for example, 50 degrees, at the moment of electrifying and starting the terminal, the main screen is determined to be in an unfolded state according to the high level still output by the Hall sensor, the main screen, namely the first screen, the second screen and the third screen, is controlled to display, and the auxiliary screen is kept in a screen-off state.
When the main screen is in a folded state, namely an included angle between the first screen and the second screen is smaller than a preset angle, for example, 50 degrees, at the moment of power-on starting of the terminal, the main screen shown in fig. 7 is determined to be in a folded state according to a low level output by the hall sensor, the auxiliary screen deviating from the first screen is controlled to display, and the main screen is kept in a screen-off state. For the main screen shown in fig. 8, according to the low level output by the hall sensor, it is determined that the main screen is in a folded state, the sub-screen deviating from the second screen is controlled to display, and the main screen is kept in a screen-off state.
For another example, for the main screen shown in fig. 9, when the terminal main screen is a folding screen including two folding regions, and the folding screen is folded along the two bending regions simultaneously to form two screens, according to different states of the terminal main screen, the terminal display interface may be displayed in the following manner, for example:
when the main screen is in a completely unfolded state, namely the first bending area and the second bending area are folded simultaneously, the included angle between the first screen and the second screen formed according to the first bending area is 180 degrees, and the included angle between the first screen and the second screen formed according to the second bending area is also 180 degrees, at the moment of power-on starting of the terminal, the main screen is determined to be in an unfolded state according to the high level output by the Hall sensor, the main screen is controlled to be displayed by the first screen and the two second screens, and the auxiliary screen is kept in a screen-off state.

By analogy, when the main screen of the terminal is a folding screen comprising more than two folding areas and the folding screen is folded along one bending area to form two screens, at the moment of powering on and starting the terminal, the terminal can display according to different states of the main screen and the terminal display interface described above. The present disclosure is not described in detail herein.
Fig. 13 is a flowchart illustrating a display method according to an exemplary embodiment, where the display method is used in a terminal, as shown in fig. 13, and includes the following steps.
In step S11, at the instant of power-on start of the terminal, the output level of the hall sensor is acquired.
At the terminal start-up moment, because terminal operating system has not completely started yet, the module of control display function still can't work in the terminal, so, this disclosure is through the power supply state of the terminal when relying on the start-up, and the perception start-up is folding screen and is located the state of expanding in the twinkling of an eye, still is fold state to according to folding screen state, control folding screen shows.
In one embodiment, the power supply control method and device can acquire the output level of the Hall sensor through the universal input and output interface after the Hall sensor is powered on at the moment of starting, and can sense the state of the main screen through the output level of the Hall sensor.
The output level of the hall sensor is used for sensing the state of the main screen, and the sensing method can be realized by the following principle:
the Hall sensor can detect the intensity of a magnetic field around the Hall sensor, and when the magnetic flux density B per unit area is detected to be larger than the trigger threshold of the Hall sensor, the Hall sensor is triggered to carry out high-low level conversion. When the distance between the Hall sensor and the magnet is very close, the magnetic field intensity detected by the Hall sensor triggers the Hall sensor to output low level, and when the distance between the Hall sensor and the magnet is very far, the magnetic field intensity detected by the Hall sensor triggers the Hall sensor to output high level.
Therefore, the display method is applied to the terminal, and the terminal comprises the main screen, the auxiliary screen, the Hall sensor and the magnet. Wherein: the main screen is a folding screen, the folding screen can comprise a plurality of bending areas, and the folding screen is folded along one bending area to form a first screen and a second screen. The secondary screen and the main screen deviate from each other. The Hall sensor is installed in the preset position of the first screen, and the magnet is installed in the second screen.
For convenience of description, the screens formed by folding the folded screen along one bending region are referred to as a first screen and a second screen.
When the main screen is in fold condition, when the main screen is folded along a bending region to form an included angle between the first screen and the second screen and is smaller than a preset angle, the positions of the Hall sensor and the magnet can be very close, and the magnetic field intensity detected by the Hall sensor triggers the Hall sensor to output a low level.
When the main screen is in an unfolded state, namely the main screen is folded along a bending area to form an included angle between the first screen and the second screen, which is larger than a preset angle and smaller than 180 degrees, the positions of the Hall sensor and the magnet are far, the magnetic field detected by the Hall sensor is weak, and the Hall sensor is triggered to output a high level.
In step S12, a main screen state is determined based on the output level of the hall sensor, the main screen state including an unfolded state and a folded state.
According to the characteristics of the Hall sensor, after the level output by the Hall sensor is obtained at the moment of starting, whether the main screen is in an unfolded state or a folded state can be determined according to the level value output by the Hall sensor.
And then, based on the preset relation between the screen state and the screen display, the main screen or the auxiliary screen can be controlled to display at the moment of starting.
When the output level of the Hall sensor is low level, the state of the main screen is determined to be a folding state. And when the main screen is in a folded state, controlling the auxiliary screen to display and keeping the main screen in a screen-off state.
And when the output level of the Hall sensor is high level, determining that the main screen state is an unfolded state. And when the main screen is in an unfolded state, controlling the main screen to display, and keeping the auxiliary screen in a screen-off state.
In addition, based on the magnetic field intensity distribution characteristics of the magnet shown in fig. 2, in order to ensure that when the main screen is folded and unfolded, the magnetic field change reaches the trigger threshold of the hall sensor, so that the output level of the hall sensor is converted into high and low levels, when the main screen is in the folded state, the hall sensor is located on one side of the direction of the first magnetic pole of the magnet, the first magnetic pole can be N-level or S-level, and the distance between the hall sensor and the first magnetic pole is smaller than the set distance threshold. I.e. the hall sensors are at four positions of the magnet in fig. 2 when the main screen is in the folded state. When the main screen is in fold condition, hall sensor sets up in the preset position of first screen promptly, and the preset position satisfies when making the main screen be in fold condition, and hall sensor is located one side of the first magnetic pole place direction of magnet, and the distance of hall sensor and first magnetic pole is less than the settlement apart from the threshold value.
In addition, in order to ensure the detection accuracy of the hall sensor, the preset position of the hall sensor is a position where the distance between the hall sensor and the terminal magnetic device exceeds a set distance threshold, and the position representation has no hard magnetic interference to the hall sensor.
For example, the hall sensor is mounted at a position away from the microphone, and a magnetic device is required for vibration and the like.
In step S13, the main screen or the sub-screen is controlled to display according to the state of the main screen.
For example, for the main screen shown in fig. 6, when the main screen is in a fully unfolded state, that is, when an included angle between the first screen and the second screen is 180 °, at the instant of power-on start of the terminal, the main screen is determined to be in an unfolded state according to a high level output by the hall sensor, the main screen is controlled to display, and the auxiliary screen is kept in a screen-off state.

When the main screen is in a folded state, namely an included angle between the first screen and the second screen is smaller than a preset angle, for example, 50 degrees, the main screen is determined to be in a folded state according to a low level output by the Hall sensor at the moment of power-on starting of the terminal, the auxiliary screen is controlled to display, and the main screen is kept in a screen-off state.
For another example, referring to the main screen shown in fig. 7, when the main screen is in a fully unfolded state, that is, an included angle between the first screen and the second screen is 180 degrees, and an included angle between the second screen and the third screen is also 180 degrees, at the instant of power-on start of the terminal, the main screen is determined to be in an unfolded state according to a high level output by the hall sensor, the main screen, that is, the first screen, the second screen and the third screen, is controlled to display, and the auxiliary screen is kept in a screen-off state. When the main screen is in a partially unfolded state, namely an included angle between the first screen and the second screen is larger than a preset angle, for example, 50 degrees, at the moment of electrifying and starting the terminal, the main screen is determined to be in an unfolded state according to the high level still output by the Hall sensor, the main screen, namely the first screen, the second screen and the third screen, is controlled to display, and the auxiliary screen is kept in a screen-off state. When the main screen is in a folded state, namely an included angle between the first screen and the second screen is smaller than a preset angle, for example, 50 degrees, the main screen is determined to be in a folded state according to a low level output by the Hall sensor at the moment of power-on starting of the terminal, the auxiliary screen deviating from the first screen is controlled to display, and the main screen is kept in a screen-off state.
In the exemplary embodiment of the disclosure, at the moment of powering on and starting the terminal, the state of the main screen of the folding screen is determined by acquiring the output level of the hall sensor, that is, it is determined whether the main screen of the folding screen is in the folded state or the unfolded state, and then the main screen and the auxiliary screen are controlled to display according to the state of the main screen and based on the display mode corresponding to the state of the main screen. Therefore, the state of the terminal screen at the moment of starting up can be sensed through the state of the terminal circuit when the terminal is started up, and the display of each screen in the terminal folding screen can be accurately controlled.
