Description

Method, device, storage medium and electronic device for determining angle between screens

Cross-reference to related applications

The present application is filed on the basis of the Chinese Patent Application No. 201101403, 214, 141, filed on Apr. 28, 2008, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present application relates to the field of communications, but is not limited to the field of communications, and in particular, to a method, device, storage medium, and electronic device for determining an angle between screens.

Background technique

A multi-display terminal (for example, a dual-screen mobile phone or a folding mobile phone, as shown in FIG. 1 and FIG. 2, but not limited to the illustrated form) needs to perform mode switching when performing single-to-multi-display switching, and the following example illustrates : See Figure 3, where:

When the Hall sensor in the terminal detects that the folding angle between the dual display areas is 0°, it is determined that the current terminal is in the folded single display state;

When the Hall sensor in the terminal detects that the folding angle between the dual display areas is greater than 0° and less than 180°, determining that the current terminal is in a state of incompletely expanding the dual display area;

When the Hall sensor in the terminal detects that the folding angle between the dual display areas is 180°, it is determined that the current terminal is in the fully expanded dual display area state;

The mode in which the terminal is currently located can be judged by a Hall sensor (for example, a digital Hall sensor) mounted on a rotating shaft between the dual display areas of the terminal; when the terminal is shipped, the manufacturer will display the dual display area. The angle between the folds is calibrated at two angles of 30° and 150°, and the two angles are used as trigger thresholds of 0° and 180°, respectively. Corresponding to the mode of the three digital Hall (Hall Sensor) angles (ie, the mode corresponding to the detected angle), the dual display area item has four display modes: single A, large A, A|B, A|A. After detecting the angle mode of the digital hall, the terminal is allowed to switch to the corresponding display mode.

As shown in FIG. 1, when the folding angle between the dual display areas is 0°, only the terminal is allowed to work in the single A display mode; when (30°, 150°), the terminal is allowed to work in the A|A display mode; For (150°, 180°), the terminal is allowed to work in both A|B and Big A display modes.

It should be noted that during the use of the digital Hall sensor, high temperature degaussing may occur, or the change of the distance between the magnet and the digital Hall sensor due to the loose shaft and the light drop may cause the magnetic flux to change.

If the magnetic flux of 0° is less than the 30° calibration threshold of the production line, the state of the digital Hall sensor “CLOSE=0°” can no longer be triggered. The display of the dual display area cannot automatically switch the display in single A mode after folding. Causes the function to fail.

Similarly, if the magnetic flux of 180° is greater than the threshold of the 150° calibration of the production line, the state of the digital Hall sensor “OPEN=180°” can no longer be triggered. The double display area cannot automatically switch between the large A and A after folding. Displayed in B mode, causing the function to fail.

Among them, the normal magnetic flux diagram is shown in Figure 4, the magnetic flux data after high temperature degaussing is shown in Figure 5.

Once the digital Hall sensor fails, the display function is abnormal, the user must take the phone to the after-sales, and re-calibrate after the sale through the angle with the calibration angle (30°-150°). Refer to Figure 6 for the calibration method. However, the method of calibration after sale leads to a low user experience and high maintenance costs.

The method of calibrating the multi-screen folding angle of the multi-screen terminal in the related art leads to the problem of high maintenance cost and low user experience, and no effective solution has been proposed yet.

In this embodiment, it is used to implement calibration of the Hall sensor at a predetermined angle,

In one embodiment, after performing a predetermined angle calibration of the Hall sensor in the terminal, the method further includes storing calibration information. Among them, the calibration value of the Hall sensor can be stored in the calibration file.

The present application is described below in conjunction with specific embodiments:

In this embodiment, the dual display area expansion angle is measured using a single triaxial acceleration to facilitate calibration of the digital Hall sensor at a particular angle as a trigger threshold for folding 0° and expanding 180°, respectively.

The angle measuring method provided in this embodiment can be applied to a dual display area terminal including an acceleration sensor. When measuring, the double display area terminal can be folded horizontally on a horizontal desktop to obtain the three-axis acceleration of the acceleration sensor output. The value (x0, y0, z0), the unit is (m/s ² ), and the obtained (x0, y0, z0) acceleration value is compared with (0, 0, 9.8), within +/- 0.5, The desktop is level.

The dual display area terminal is deployed on the horizontal desktop to obtain the three-axis acceleration value (x1, y1, z1) of the acceleration sensor output, and the unit is (m/s ² );

The y-axis acceleration value y1 is 0 +/- 0.5, and the expanded Y-axis and ground level are confirmed.

In the case where the above conditions are satisfied, the double display area expansion angle is calculated by the values x1, z1 of the x-axis and the z-axis.

Wherein, stationary acceleration level placed on a horizontal table, x and y-axis with the ground level, a value of 0m / s ^2; z-axis perpendicular to the ground, by the action of gravity, a value of 9.8m / s ^2.

In some embodiments, placing the dual display area terminal on a horizontal table top is also subject to gravity. Using this property, one side is calculated by measuring the component of the gravitational acceleration on the x and y axes of the acceleration sensor. The angle of inclination on the vertical plane, and then the angle of expansion of the dual display area is calculated by symmetry.

As shown in Figure 10,

Expansion angle of the dual display area

Wherein, when the acceleration sensor is on the left main screen, the values of the x and z axes are positive values; when the acceleration sensor is on the left main screen, the value of the x axis is a negative value; the value of the z axis is a positive value, at this time, Take the absolute value of the value of the x-axis.

When the desktop is not horizontal, the angle between the two screens can also be calculated by the acceleration acceleration sensor's three-axis acceleration value, but it is more complicated for the user, and the terminal is placed in a more posture, and is used less in practical applications.

When the terminal is placed on a tilted tabletop (corresponding to the aforementioned plane), there are many ways to place the terminal, but the vector sum of (x, y, z) is a gravitational acceleration of 9.8 m/s ² .

After folding the terminal horizontally on the inclined table top, as shown in Fig. 11, the tilt angle θ of the table top can be calculated by the value of the three-axis acceleration (x, y, z).

Wherein, when the Y axis of the mobile phone is parallel to the inclined surface of the desktop,

The expansion angle of the dual display area:

When the Y-axis of the phone is perpendicular to the cross-section of the inclined surface of the tabletop, the Y-axis is level with the ground and has a value of zero. Assume that the accelerometer is on the main screen on the left side of the terminal, as shown in Figure 12:

The expansion angle of the dual display area:

Where x and z are vector values with positive and negative signs.

When the mobile phone is fully deployed on the inclined surface, α=-θ+θ=0°, β=180°;

When the main screen of the mobile phone is level with the ground, α=θ, β=180°-2θ;

In particular, when the table top is not horizontal (for example, as shown in FIG. 13), the angle between the two screens can also be calculated by the three-axis acceleration value of the acceleration sensor, and then the three angles placed on the desktop are expanded at a certain angle. The axis acceleration value combined with the tilt angle of the desktop can also calculate the angle at which the dual display area is expanded.

The following is an example of calibrating a Hall sensor in a mobile phone to illustrate the overall calibration process on a horizontal desktop:

FIG. 14 is a calibration flow of a Hall sensor according to an embodiment of the present application. As shown in FIG. 14, the method includes the following steps:

S1404: Prompt the user to place the mobile phone on the desktop to check whether the desktop is level:

S1406: determining whether the desktop is horizontal, if the determination result is yes, go to S1408, otherwise go to S1416;

S1408: The prompt is used to deploy the dual display area of the mobile phone on the horizontal desktop, and calculate the angle between the two screens in real time;

S1410: If the angle measured in real time is less than the preset calibration angle, the user is prompted to slowly expand the dual display area; if the angle measured in real time is greater than the preset calibration angle, the user is prompted to slowly fold the double display area until the clip The angle is equal to the predetermined calibration angle;

S1412: receiving a calibration command (which may be an instruction triggered by a user pressing a calibration button), and writing a calibration value of the Hall sensor into the calibration file;

S1414: Entering the comprehensive test interface, prompting the user to perform 180° state detection. When detecting that the user expands the angle of the double display area from 150° to 180°, the prompt is completed;

S1416: Prompt the user to adjust the desktop of the mobile phone. If the desktop is still detected as a non-horizontal desktop, exit the calibration process.
