Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, a schematic diagram of a folding screen terminal 01 to which a document page turning method provided by an embodiment of the present application is applied is shown. The folding screen terminal 01 can be a folding screen smart phone or a folding screen tablet computer and the like. As shown in fig. 1, the folder terminal may have two

display screens

011 and 012, each of which is capable of being rotated in a direction approaching or departing from the other display screen. For example, the display 012 in the folder terminal shown in fig. 1 may be rotated in a direction approaching the display 011.

Fig. 2 is a flowchart of a document page turning method according to an embodiment of the present application. The document page turning method may be applied to the folding screen terminal 01 shown in fig. 1, and as can be seen with reference to fig. 2, the document page turning method may include:

step 101, displaying a document in a target display screen of the two display screens.

In the embodiment of the application, a reading client can be installed in the folding screen terminal, and after the reading client is started, a document can be displayed through a target display screen in the two display screens so that a user can view the document conveniently. The target display screen may be one display screen or two display screens.

For example, assuming that the two display screens are both the target display screen, when the folder terminal displays a document in the two display screens, the contents of the document displayed in the two display screens may be different. For example, each display may display the content of one page of the document, and the two displays display the content of two adjacent pages.

And 102, acquiring the posture parameters of each display screen.

The folding screen terminal can acquire the attitude parameters of each display screen in real time, or can acquire the attitude parameters of each display screen once every time threshold. The gesture parameter of the display screen acquired by the folding screen terminal may be an angular velocity.

And 103, determining the rotation direction of the display screen according to the posture parameter of each display screen.

In the embodiment of the present application, the gesture parameter of each display screen may be a vector parameter. The folding screen terminal can determine the rotation direction of each display screen according to the direction of the vector parameter.

For example, when the direction of the posture parameter of one of the two display screens points to the other display screen, the rotation direction of the one display screen may be determined to be a direction close to the second display screen, and when the direction of the posture parameter of the first display screen faces away from the second display screen, the rotation direction of the first display screen may be determined to be a direction away from the second display screen.

And step 104, if the two display screens meet the page turning condition according to the rotation direction, performing page turning operation on the document displayed in the target display screen.

In this embodiment, the page turning condition may include: after one display screen rotates towards the direction close to the other display screen, the other display screen rotates towards the direction far away from the other display screen. The performing of the page turning operation on the document displayed in the target display screen may refer to displaying a previous page content of the current page or displaying a next page content of the current page on the target display screen in the folding screen terminal.

For example, assume that the target display is one of two displays. When the folding screen terminal detects that the target display screen rotates towards the direction close to the other display screen firstly and then rotates towards the direction far away from the other display screen, page turning operation is performed on the document displayed in the target display screen.

To sum up, the embodiment of the present application provides a document page turning method, which may obtain an attitude parameter of each display screen after a document is displayed in a target display screen of two display screens, determine a rotation direction of the display screen according to the attitude parameter of each display screen, and perform a page turning operation on the document displayed by the target display screen when it is determined that the two display screens satisfy a page turning condition according to the rotation direction. Because the folding screen terminal can automatically execute page turning operation on the document displayed in the target display screen according to the posture of the display screen, page turning can be realized without executing sliding operation or clicking operation on the display screen by a user, and the page turning reliability is better.

FIG. 3 is a flowchart of another document page turning method according to an embodiment of the present application. The document page turning method may be applied to the folding screen terminal 01 shown in fig. 1. As can be seen with reference to fig. 3, the method may comprise:

step 201, a document is displayed in a target display screen of the two display screens.

In the embodiment of the application, the folding screen terminal can be provided with a reading client, and after the reading client is started, a document can be displayed through a target display screen in the two display screens so as to be conveniently viewed by a user. The target display screen may be one display screen or two display screens.

For example, assuming that the two display screens are both the target display screen, when the folding screen terminal displays a document in the two display screens, the contents of the document displayed in the two display screens may be different. For example, each display screen may display the content of one page in the document, and the two display screens display the content of two adjacent pages.

Referring to fig. 4, assuming that a document displayed in a folder terminal includes P pages and that a first display 0111 and a second display 012 in the folder terminal are both target displays, P +1 page contents of the document can be displayed in the first display 0111 and P page contents of the document can be displayed in the second display 012. Wherein, P can be a positive integer greater than 1, and both P and P +1 are positive integers greater than or equal to 1 and less than or equal to P.

Step 202, acquiring a first axis angular velocity of each display screen through a sensor arranged in each display screen.

In this embodiment of the application, a sensor may be disposed in each display screen, and the foldable screen terminal may acquire the first axis angular velocity of the display screen through the sensor. Wherein the first axis may be perpendicular to the display screen, and since the first axis of the display screen is perpendicular to the display screen, the first axis angular velocity of the display screen may also be perpendicular to the display screen.

As an alternative implementation, the sensor provided in each display screen may include: gravity acceleration sensor, referring to fig. 5, step 202 may comprise:

step 2021a, acquiring a first axis acceleration, a second axis acceleration and a third axis acceleration of the display screen through a gravity acceleration sensor arranged in each display screen.

In the embodiment of the present application, a first gravitational acceleration sensor may be disposed in the first display screen, and a second gravitational acceleration sensor may be disposed in the second display screen. The folding screen terminal can acquire the first axis acceleration, the second axis acceleration and the third axis acceleration of the first display screen through the first gravity acceleration sensor, and the folding screen terminal can acquire the first axis acceleration, the second axis acceleration and the third axis acceleration of the second display screen through the second gravity acceleration sensor.

Wherein, referring to fig. 6, the first axis (Z axis) is perpendicular to the display screen, both the second axis (X axis) and the third axis (Y axis) may be parallel to the display screen, and the second axis may be perpendicular to the third axis. For example, the second axis may be parallel to an axis of rotation between the first display screen and the second display screen, and the third axis may be perpendicular to the axis of rotation between the first display screen and the second display screen.

For each display screen, the first axis is perpendicular to the display screen, and the second and third axes are parallel to the display screen, independent of the other display screens. For example, in fig. 6, a first axis of the first display screen 011 is perpendicular to the first display screen 011, and a second axis and a third axis are parallel to the first display screen 011.

For example, when a display screen is parallel to a horizontal plane, the display plane is upward relative to the non-display plane (e.g., lying on a table in a forward direction), and the display screen is in a static state, the first axial acceleration of the display screen detected by the gravitational acceleration sensor in the display screen is the gravitational acceleration of the display screen, i.e., 9.8m/s ² (meters per second of square), the second axis acceleration and the third axis acceleration detected are both 0m/s ² 。

When a certain display screen is parallel to the horizontal plane, the display plane faces upwards relative to the non-display plane (for example, the display screen is horizontally placed on a table reversely), and the display screen is in a static state, the first-axis acceleration of the display screen detected by the gravity acceleration sensor in the display screen is the reverse gravity acceleration of the display screen, namely-9.8 m/s ² The detected second axis acceleration and the third axis acceleration are both 0m/s ² 。

The gravity acceleration sensor may also be referred to as a gravity sensor or an acceleration sensor.

Step 2022a, determining a first axis angular velocity of the display screen according to the first axis acceleration, the second axis acceleration and the third axis acceleration of the display screen.

In the embodiment of the application, the gravity acceleration sensor in each display screen can acquire the first axis acceleration, the second axis acceleration and the third axis acceleration of the display screen once every time threshold. The time threshold may be 50ms (milliseconds).

Taking the first display screen as an example, the process of determining the first axis angular velocity of the first display screen by the folding screen terminal according to the first axis acceleration, the second axis acceleration and the third axis acceleration of the first display screen is described, which includes:

(1) and determining a first angle of the first axis of the first display screen relative to the horizontal plane according to the first axis acceleration, the second axis acceleration and the third axis acceleration of the first display screen which are acquired for the first time.

(2) And determining a second angle of the first axis of the first display screen relative to the horizontal plane according to the first acceleration, the second axis acceleration and the third axis acceleration of the first display screen acquired for the second time.

(3) And determining the first axis angular velocity of the first display screen according to the interval time between the first acquisition and the second acquisition, the first angle and the second angle.

Optionally, the first axis angle of the first display screenSpeed omega _z Can satisfy the following conditions:

in the above formula (1), A1 _z May be a first angle, a2, of a first axis of the first display screen acquired for a first time relative to a horizontal plane _z The second angle of the first axis of the first display screen relative to the horizontal plane may be acquired a second time, and t may be an interval between the first acquisition and the second acquisition.

The acceleration of each axis of the first display screen acquired for the first time and the acceleration of each axis of the first display screen acquired for the second time may be the acceleration of each axis of the first display screen acquired by the first gravitational acceleration sensor in two adjacent times, or the acceleration of each axis of the first display screen acquired by the first gravitational acceleration sensor at multiple intervals.

In this embodiment of the application, each time the angle of the first axis of the first display screen relative to the horizontal plane is determined, the radian of the first axis of the first display screen relative to the horizontal plane may be determined according to the first axis acceleration, the second axis acceleration, and the third axis acceleration of the first display screen. And determining the angle of the first axis of the first display screen relative to the horizontal plane according to a conversion formula of the radian and the angle. Wherein, the conversion formula of the radian theta and the angle beta satisfies the following conditions: β ═ θ × 180 °)/pi. Pi may typically take 3.14.

Optionally, the radian theta of the first axis of the first display screen relative to the horizontal plane _z Can satisfy the following conditions:

in the formula (2), az is a first axis acceleration of the first display screen detected by the gravitational acceleration sensor, ax is a second axis acceleration of the first display screen detected by the gravitational acceleration sensor, and ay is a third axis acceleration of the first display screen detected by the gravitational acceleration sensor.

According to the aboveThe conversion formula of radian and angle shows that the angle beta of the first axis of the first display screen relative to the horizontal plane _z Satisfies the following conditions: beta is a _z ＝(θ _z ×180)/π。

As another alternative implementation, the sensor provided in each display screen may include: gravity acceleration sensor and gyroscope, referring to fig. 7, step 202 may include:

step 2021b, acquiring a first axis acceleration, a second axis acceleration and a third axis acceleration of the display screen through a gravity acceleration sensor arranged in each display screen.

For example, when a display screen is parallel to a horizontal plane, the display plane is facing upward relative to the non-display plane (e.g., flat on a table in a forward direction), and the display screen is in a static state, the first axial acceleration of the display screen detected by the acceleration sensor in the display screen is the acceleration of gravity of the display screen, i.e., 9.8m/s ² The detected second axis acceleration and the third axis acceleration are both 0m/s ² 。

Step 2022b, determining the first axis angular velocity, the second axis angular velocity and the third axis angular velocity of the display screen according to the first axis acceleration, the second axis acceleration and the third axis acceleration of the display screen respectively.

In the embodiment of the application, the gravity acceleration sensor in each display screen can acquire the first axis acceleration, the second axis acceleration and the third axis acceleration of the display screen once every time threshold. The time threshold may be 50 ms.

Taking the first display screen as an example, introducing a process of determining a certain axis angular velocity of the first axis angular velocity, the second axis angular velocity and the third axis angular velocity of the first display screen according to the first axis acceleration, the second axis acceleration and the third axis acceleration of the first display screen by the folding screen terminal, including:

(1) and determining a first angle of a certain axis of the first display screen relative to a horizontal plane according to the first axis acceleration, the second axis acceleration and the third axis acceleration of the first display screen which are acquired for the first time.

(2) And determining a second angle of a certain axis of the first display screen relative to the horizontal plane according to the first acceleration, the second axis acceleration and the third axis acceleration of the first display screen acquired for the second time.

(3) And determining a certain axial angular velocity of the first display screen according to the interval time between the first acquisition and the second acquisition, the first angle and the second angle.

Alternatively, if a certain axis is the first axis of the first display screen, the equation (1) may be referred to for determining the first axis angular velocity of the first display screen. If a certain axis is the second axis of the first display screen, the second axis angular velocity ω of the first display screen _x Can satisfy the following conditions:

in the above formula (3), A1 _x May be a first angle, a2, of a first acquired second axis of the first display screen relative to the horizontal plane _x The second angle of the second axis of the first display screen relative to the horizontal plane may be acquired a second time.

If a certain axis is the firstA third axis of the display screen, the third axis angular velocity ω of the first display screen _y Can satisfy the following conditions:

in the above formula (4), A1 _y May be a first angle, a2, of the first axis of the first display screen relative to the horizontal plane acquired for the first time _y The second angle of the third axis of the first display screen relative to the horizontal plane may be acquired for the second time.

It should be noted that, each time the angle of the first axis of the first display screen relative to the horizontal plane, the angle of the second axis relative to the horizontal plane, and the angle of the third axis relative to the horizontal plane are determined, the radian of the first axis of the first display screen relative to the horizontal plane, the radian of the second axis relative to the horizontal plane, and the radian of the third axis relative to the horizontal plane may be determined according to the first axis acceleration, the second axis acceleration, and the third axis acceleration of the first display screen. And determining the angle of the first axis of the first display screen relative to the horizontal plane according to a conversion formula of the radian and the angle. Wherein, the conversion formula of the radian theta and the angle beta satisfies the following conditions: β ═ (θ × 180 °)/π. Pi may typically take 3.14.

Optionally, the radian theta of the first axis of the first display screen relative to the horizontal plane _z Reference may be made to the above formula (2). Radian theta of second axis of first display screen relative to horizontal plane _x Can satisfy the following conditions:

radian theta of third axis of first display screen relative to horizontal plane _y Can satisfy the following conditions:

wherein, the conversion formula of the radian and the angle is usedIt can be seen that the first axis of the first display screen is at an angle β with respect to the horizontal plane _z Satisfies the following conditions: beta is a _z ＝(θ _z X 180)/π. Angle beta of second axis of first display screen relative to horizontal plane _x Satisfies the following conditions: beta is a _x ＝(θ _x X 180)/π. Angle beta of third axis of first display screen relative to horizontal plane _y Satisfies the following conditions: beta is a _y ＝(θ _y ×180)/π。

Step 2023b, if it is detected that the angular velocity of at least one axis of the display screen changes and the changed angular velocity is greater than the first angular velocity threshold, starting a gyroscope in the display screen, and obtaining the first axis angular velocity of the display screen through the gyroscope.

In this application embodiment, because the precision of each axle acceleration that the acceleration of gravity sensor detected is lower, and then influences the first axle angular velocity that determines according to this each axle acceleration, consequently folding screen terminal can set up first gyroscope in first display screen for the accuracy that improves the first axle angular velocity who acquires, sets up the second gyroscope in the second display screen. The first gyroscope may detect a first axis angular velocity of the first display screen. The second gyroscope may detect a first axis angular velocity of the second display screen.

Furthermore, because the power consumption of the gyroscope is relatively large, in order to reduce the power consumption, the gyroscope in the display screen may be turned off under the condition that the display screen is stationary, acceleration of each axis of the display screen may be obtained through a gravitational acceleration sensor in the display screen, and then each axis angular velocity may be determined according to the obtained acceleration of each axis.

For example, assuming that the folded screen terminal detects that the angular velocity of at least one axis of the first display screen changes, the changed angular velocity is greater than the first angular velocity threshold, and it detects that the angular velocities of the axes of the second display screen do not change, only the first gyroscope disposed in the first display screen may be started. That is, the gyroscope in the first display screen is used to detect the first axis angular velocity of the first display screen, and for the second display screen, the gravitational acceleration sensor in the second display screen is used to detect the acceleration of each axis of the second display screen, and then the first axis angular velocity of the second display screen is determined according to the acceleration of each axis.

When the angular velocity of at least one of the axis angular velocities of the display screen determined according to the gravity acceleration sensor is greater than the first angular velocity threshold value, in order to improve the accuracy of the first axis angular velocity of the display screen acquired by the folding screen terminal, the folding screen terminal may start a gyroscope in the display screen, and the first axis angular velocity of the display screen is acquired through the gyroscope. At this time, because the gravitational acceleration sensor in the display screen is still in the on state, the folding screen terminal can also determine each axial angular velocity according to each axial acceleration of the display screen obtained by the gravitational acceleration sensor, but the folding screen terminal can ignore each axial angular velocity determined according to each axial acceleration of the display screen obtained by the gravitational acceleration sensor, and determine the rotation direction of the display screen only according to the first axial angular velocity of the display screen obtained by the gyroscope.

It should be noted that the first angular velocity threshold may be preset for the folding screen terminal. Alternatively, the first angular velocity threshold may be 10 °/s (degrees/second). Assuming that the first axis angular velocity in a certain display screen determined according to the acceleration of each axis acquired by the gravity acceleration sensor in the display screen is greater than 10 DEG/s, the folded screen terminal can start the gyroscope arranged in the display screen.

Step 2024b, if each display screen is determined according to the first axis acceleration, the second axis acceleration and the third axis acceleration of each display screen, and the rotating shaft between the two display screens is perpendicular to the horizontal plane, starting a gyroscope in each display screen, and obtaining the first axis angular velocity of each display screen through the gyroscope.

In the embodiment of the present application, referring to fig. 8, when both the two display screens in the folding screen terminal are perpendicular to the horizontal plane and the rotating shaft between the two display screens is perpendicular to the horizontal plane, it may be determined that the gravitational acceleration sensor is in the detection blind area. At this time, the folding screen terminal may simultaneously start the first gyroscope disposed on the first display screen and the second gyroscope disposed on the second display screen.

It should be noted that, in the following description,two display screens are all perpendicular to the horizontal plane, and when the pivot perpendicular to horizontal plane between two display screens, the reason that acceleration of gravity sensor is in the blind area lies in: when the two display screens are perpendicular to the horizontal plane and the rotating shaft between the two display screens is perpendicular to the horizontal plane, the first shaft of each display screen in the two display screens is parallel to the horizontal plane, the second shaft is perpendicular to the horizontal plane, and the third shaft is parallel to the horizontal plane. Therefore, the first axial acceleration of the display screen detected by the gravity acceleration sensor arranged in each display screen is always 0m/s ² The second axis acceleration is always 9.8m/s ² The third axis acceleration is always 0m/s ² . At this time, according to the acceleration of each axis detected by the gravity acceleration sensor, it can be determined that the angle of the first axis of the display screen with respect to the horizontal plane is always 0 degree, the angle of the second axis with respect to the horizontal plane is always 90 degrees, and the angle of the third axis with respect to the horizontal plane is always 0 degree. That is, no matter what state the two display screens in the folding screen terminal are, the angular speed of each axis cannot be determined according to the change of the angle of each axis and the angle acquisition time interval. The folding screen terminal cannot determine the rotation state of the display screen according to the detection result of the gravity acceleration sensor. Therefore, when the two display screens are both vertical to the horizontal plane and the rotating shaft between the two display screens is vertical to the horizontal plane, the gravity acceleration sensor is in a detection blind area.

And step 203, acquiring a second axis angular velocity and a third axis angular velocity of the display screen.

The second axis acceleration and the third axis acceleration of each display screen can also be obtained by the folding screen terminal, and the process of obtaining the second axis acceleration and the third axis acceleration of each display screen can refer to the process of obtaining the first axis acceleration in step 202, which is not described herein again in this embodiment of the application.

And 204, if the target shaft angular speed with the largest angular speed value among the first shaft angular speed, the second shaft angular speed and the third shaft angular speed is greater than a second angular speed threshold value, adjusting the detection frequency of the sensor according to the target shaft angular speed.

In this embodiment of the application, if the angular velocity of each axis of the display screen acquired by the folding screen terminal according to the sensor in a certain display screen is small, it indicates that the display screen does not rotate significantly in a short time, and therefore the folding screen terminal can reduce the detection frequency of the sensor arranged in the display screen, so as to reduce power consumption. If the angular velocity of at least one axis of the angular velocities of the axes of the display screen, which is acquired by the folding screen terminal according to the sensor in a certain display screen, is large, it is indicated that the display screen may rotate obviously in a short time, and therefore the folding screen terminal can improve the detection frequency of the sensor arranged in the display screen, so that the folding screen terminal can acquire the first axis angular velocity of the display screen more accurately. Wherein, the adjusted detection frequency of the sensor can be positively correlated with the target shaft angular speed.

As a possible situation, if neither of the two display screens in the folding screen terminal is provided with a gyroscope or the gyroscopes in the two display screens are not turned on, the folding screen terminal detects each axis acceleration of the display screen by using a gravity acceleration sensor arranged in the display screen, and determines each axis angular velocity of the display screen according to the each axis acceleration, and when a target axis angular velocity with a maximum angular velocity value among the axis angular velocities is greater than a second angular velocity threshold value, the folding screen terminal may adjust a detection frequency of the gravity acceleration sensor arranged in the display screen according to the target axis angular velocity.

As another possible situation, if two display screens in the folding screen terminal are both provided with gyroscopes, and the gyroscopes in a certain display screen are in an on state. At this time, when a target axis angular velocity with the largest angular velocity value among the first axis angular velocity, the second axis angular velocity, and the third axis angular velocity of the display screen is greater than a second angular velocity threshold, the foldable screen terminal may adjust the detection frequency of the gyroscope disposed in the display screen according to the target axis angular velocity. The first axis angular velocity, the second axis angular velocity and the third axis angular velocity of the display screen can be determined by the folding screen terminal according to the acceleration of each axis detected by a gravity acceleration sensor arranged in the display screen. Alternatively, the first axis angular velocity, the second axis angular velocity, and the third axis angular velocity of the display screen may also be detected by the folding screen terminal according to a gyroscope provided in the display screen.

In the embodiment of the present application, the adjusted detection frequency of the sensor may be linearly and positively correlated with the target shaft angular velocity. Alternatively, as shown in table 1, the folding screen terminal may store in advance a plurality of correspondence relationships between angular velocity ranges and detection frequencies. When a target shaft angular velocity with the largest angular velocity value among the first shaft angular velocity, the second shaft angular velocity and the third shaft angular velocity of a certain display screen is greater than a second angular velocity threshold, the folding screen terminal may first determine an angular velocity range in which the target shaft angular velocity is located, and determine a target detection frequency corresponding to the angular velocity range in which the target shaft angular velocity is located according to a corresponding relationship between the angular velocity range and the detection frequency shown in table 1. And then, the folding screen terminal can adjust the detection frequency of the sensor to the target detection frequency.

TABLE 1

Angular velocity range	Detecting frequency
		(10°/s，15°/s]	20Hz
(15°/s，30°/s]	30Hz
		(30°/s，40°/s]	50Hz
(40°/s，+∞]	100Hz

For example, assuming that the second angular velocity threshold value is 10 °/s, when a target shaft angular velocity having a maximum angular velocity value among shaft angular velocities of a certain display screen is greater than 10 °/s and equal to or less than 15 °/s, the folding screen terminal may adjust a detection frequency of a sensor provided in the display screen to 20Hz (hertz). When the target axial angular velocity with the largest angular velocity value among the axial angular velocities of a certain display screen is greater than 15 °/s and less than or equal to 30 °/s, the folding screen terminal may adjust the detection frequency of the sensor disposed in the display screen to 30 Hz. When the target axial angular velocity with the largest angular velocity value among the axial angular velocities of a certain display screen is greater than 30 °/s and equal to or less than 40 °/s, the folding screen terminal may adjust the detection frequency of the sensor provided in the display screen to 50 Hz. When the target axis angular velocity with the largest angular velocity value among the axis angular velocities of a certain display screen is greater than 40 °/s, the folding screen terminal may adjust the detection frequency of the sensor disposed in the display screen to 100 Hz.

Step 205, if the direction of the first axis angular velocity of the first display screen is detected to point to the second display screen of the two display screens, determining that the rotation direction of the first display screen is a direction close to the second display screen.

In this embodiment, the folding screen terminal may determine the rotation direction of the first display screen by detecting the direction of the first axis of the first display screen.

Because the first axis of the first display screen is perpendicular to the first display screen, when the first display screen rotates towards the direction close to the second display screen, the first axis of the first display screen perpendicular to the first display screen can also rotate towards the direction close to the second display screen, and the first axis of the first display screen can point to the second display screen. Therefore, the folding screen terminal can determine that the rotation direction of the first display screen is a direction close to the second display screen when detecting that the direction of the first axis angular velocity of the first display screen points to the second display screen.

Step 206, if the direction of the first axis angular velocity of the first display screen is detected to be back to the second display screen, determining that the rotation direction of the first display screen is a direction far away from the second display screen.

In this embodiment, when the first display screen rotates in a direction away from the second display screen, a first axis of the first display screen perpendicular to the first display screen may also rotate in a direction away from the second display screen, and the first axis of the first display screen may face away from the second display screen. Therefore, when the folding screen terminal detects that the direction of the first axis angular velocity of the first display screen is opposite to the second display screen, the folding screen terminal can determine that the rotating direction of the first display screen is away from the second display screen.

And step 207, if the first display screen is close to the second display screen and then is far away from the second display screen, displaying the next page content of the current page on the target display screen.

In this embodiment, the first display screen may be a primary screen, and the second display screen may be a secondary screen. When a user views a document through the folding screen terminal, the first display screen may be located on the right side of the rotating shaft between the two display screens, and the second display screen may be located on the left side of the rotating shaft between the two display screens.

If the direction of the first axis angular velocity of the first display screen detected by the folding screen terminal points to the second display screen, namely the first display screen rotates towards the second display screen, and then the direction of the first axis angular velocity of the first display screen is detected to be back to the second display screen, namely the first display screen rotates away from the second display screen, the folding screen terminal can determine that the first display screen and the second display screen meet page turning conditions according to the rotation direction of the first display screen, and at the moment, next page content of a current page can be displayed on a target display screen.

Referring to fig. 9, it is assumed that a document displayed in the folder terminal includes P pages, the first display and the second display are both target displays, and the content displayed in the first display is a content next to the content displayed in the second display. If the first display screen 011 first approaches the second display screen 012 in the counterclockwise direction m and then leaves the second display screen 012 in the clockwise direction n, the next page of the content displayed on the first display screen 011 at present is displayed on the second display screen 012, and the next page of the content displayed on the second display screen 012 is displayed on the first display screen 011. For example, if the second display screen 012 currently displays p pages and the first display screen 011 currently displays p +1 pages, when the first display screen 011 first approaches the second display screen 012 and then moves away from the second display screen 012, p +2 pages are displayed on the second display screen 012 and p +3 pages are displayed on the first display screen 011. Wherein P may be a positive integer greater than 1. P, P +1, P +2, and P +3 are positive integers greater than or equal to 1 and less than or equal to P.

Before determining the page turning condition, in order to simulate the page turning state of the user during reading, gesture recognition and extraction may be performed on the page turning action of the paper book, and a page turning flow is determined. The first display screen in the folding screen terminal can be equivalent to the first surface of a paper book, and the second display screen can be equivalent to the second surface of the paper book.

Taking an example of turning a page of a paper book backward, assuming that the paper book includes H pages, when a user views the paper book, a second side (left side) of the paper book may be H pages, and a first side (right side) of the paper book may be H +1 pages. When a user needs to turn pages, the first surface of the paper book can be lifted, and the first surface is rotated to be close to the second surface. In the process that the first surface rotates towards the second surface, the first surface can accelerate and rotate along the anticlockwise direction, and then decelerate and rotate along the anticlockwise direction. After page turning is completed, the second surface of the paper book is h +2 pages, and the first surface of the paper book is h +3 pages. Wherein the second side of the paper book remains stationary during the page turning process. Wherein, H can be a positive integer greater than 1, and H, H +1, H +2, and H +3 are all positive integers greater than or equal to 1 and less than or equal to H.

Through the analysis of the page turning process of the paper book, it can be determined that when the page of the folding screen terminal is turned, the first display screen and the second display screen need to be in an open state, and the included angle between the first display screen and the second display screen is larger than the angle threshold value. For example, the angle threshold is 120 degrees. Before page turning is carried out, the first display screen and the second display screen are in a relatively stable state, or the folding screen terminal is shaken in a small amplitude mode because a user holds the folding screen terminal, but the first display screen and the second display screen do not rotate relatively. In the page turning process, when the angular velocity of at least one axis of a certain display screen changes, the certain display screen can be accelerated to approach another display screen, then decelerated to approach another display screen, and then still when the certain display screen has a certain angle with the another display screen. At this time, the included angle between the two display screens is small, which is not beneficial to viewing documents, so that the display screen needs to be rotated away from the other display screen. In the process that the display screen is far away from the other display screen, the display screen is accelerated to be far away from the other display screen, and then is decelerated to be far away from the other display screen. After the page is turned, the display screen may be in a position before the page is turned.

According to the analysis, after one display screen rotates towards the direction close to the other display screen, the display screen rotates towards the direction far away from the other display screen, and the folding screen terminal can perform page turning operation on the document displayed in the target display screen. In addition, when the first display screen on the right side of the two display screens is close to the second display screen and is far away from the second display screen, the next page of content of the current page can be displayed on the target display screen, the reading habit of paper books of a user is met, and the user experience is good.

And 208, if the direction of the first-axis angular speed of the second display screen is detected to point to the first display screen of the two display screens, determining the rotating direction of the second display screen to be the direction close to the first display screen.

In this embodiment, the folding screen terminal may determine the rotation direction of the second display screen by detecting the direction of the first axis of the second display screen.

Because the first axis of the second display screen is perpendicular to the second display screen, when the second display screen rotates towards the direction close to the first display screen, the first axis of the second display screen perpendicular to the second display screen can also rotate towards the direction close to the first display screen, and the first axis of the second display screen can point to the first display screen. Therefore, the folding screen terminal can determine that the rotation direction of the second display screen is a direction close to the first display screen when detecting that the direction of the first axis angular velocity of the second display screen points to the first display screen.

Step 209, if the direction of the first axis angular velocity of the second display screen is detected to be back to the first display screen, determining that the rotation direction of the second display screen is a direction far away from the first display screen.

In this embodiment of the application, when the second display screen rotates towards the direction away from the first display screen, the first axis of the second display screen perpendicular to the second display screen may also rotate towards the direction away from the first display screen, and the first axis of the second display screen may face away from the first display screen. Therefore, when the folding screen terminal detects that the direction of the first axis angular velocity of the second display screen faces away from the first display screen, it may be determined that the rotation direction of the second display screen is a direction away from the first display screen.

And step 210, if the second display screen is close to the first display screen and then is far away from the first display screen, displaying the previous page content of the current page on the target display screen.

In this embodiment of the application, if the foldable screen terminal detects that the direction of the first axial angular velocity of the second display screen points to the first display screen first, that is, the second display screen rotates toward the first display screen first, and then detects that the direction of the first axial angular velocity of the second display screen faces away from the first display screen, that is, the second display screen rotates away from the first display screen, the foldable screen terminal may determine that the first display screen and the second display screen meet the page turning condition according to the rotation direction of the second display screen, and at this time, may display the previous page content of the current page on the target display screen.

Referring to fig. 10, it is assumed that a document displayed in the folder terminal includes P pages, the first display and the second display are both target displays, and the content displayed in the first display 011 is the content of the next page of the content displayed in the second display 012. If the second display screen approaches the first display screen in the clockwise direction m and then leaves the first display screen 011 in the counterclockwise direction n, the previous page of the content displayed on the second display screen 012 is displayed on the first display screen 011, and the previous page of the content displayed on the first display screen 011 is displayed on the second display screen 012. For example, if the second display screen 012 displays p pages currently and the first display screen 011 displays p +1 pages currently, when the second display screen 012 approaches the first display screen 011 first and then moves away from the first display screen 011, the first display screen 011 displays p-1 pages and the second display screen 012 displays p-2 pages. Wherein P may be a positive integer greater than 1. P, P +1, P-1, and P-2 are positive integers greater than or equal to 1 and less than or equal to P.

Because the second display screen positioned on the left sides of the two display screens is close to the first display screen firstly and then far away from the first display screen, the previous page content of the current page is displayed on the target display screen, the reading habit of paper books of a user is met, and the user experience is better.

In the embodiment of the application, when a user closes the folding screen terminal, one of the first display screen and the second display screen does not rotate away from the other display screen after rotating towards the other display screen. At this time, if the target display screen still displays the document, the one display screen may be rotated away from the other display screen for the next time the user unfolds the folding screen terminal. The folding screen terminal can determine that the two display screens meet page turning conditions according to the rotation direction of the display screens, and performs page turning operation on the document displayed by the target display screen. Therefore, in order to enable the folding screen terminal not to perform a page turning operation under such a condition and improve user experience, the page turning condition may further include: after one of the first display screen and the second display screen rotates towards the direction close to the other display screen, the display screen rotates towards the direction far away from the other display screen within the duration threshold value. Alternatively, the duration threshold may be 30 s.

When the first axis angular velocity, the second axis angular velocity and the third axis angular velocity detected by the sensor arranged in the first display screen are respectively equal to the first axis angular velocity, the second axis angular velocity and the third axis angular velocity detected by the sensor arranged in the second display screen, and the directions of the second axis angular velocity and the third axis angular velocity are the same, it can be determined that the first display screen and the second display screen rotate towards the same direction, namely, the whole inclination of the folding screen terminal is caused by the body inclination when a user holds the folding screen terminal by hand. At this time, because each of the two display screens in the folding screen terminal does not rotate towards the direction close to or away from the other display screen, the folding screen terminal may determine that the two display screens do not satisfy the page turning condition, and may not perform the page turning operation on the document displayed on the target display screen. The document page turning method provided by the embodiment of the application can determine whether the two display screens meet the page turning condition according to the rotation directions of the two display screens, and the page turning reliability is better because the rotation directions of the two display screens are not independently judged.

It should be noted that, after the folding screen terminal performs a page turning operation on a document displayed in the target display screen, in order to reduce power consumption, the turned-on gyroscope may be turned off, and only the acceleration of the display screen is detected by using the gravitational acceleration sensor.

It should be further noted that the sequence of the steps of the document page turning method provided in the embodiment of the present application may be appropriately adjusted, and the steps may also be increased or decreased according to the situation. For example, step 205 to step 210 may be performed before step 203, step 203 and step 204 may be deleted according to the circumstances, and any method that can be easily conceived by those skilled in the art within the technical scope disclosed herein shall be covered by the protection scope of the present application, and thus, the description thereof shall not be repeated.

To sum up, the embodiment of the present application provides a document page turning method, which may include obtaining a posture parameter of each display screen after a document is displayed in a target display screen of two display screens, determining a rotation direction of the display screen according to the posture parameter of each display screen, and performing a page turning operation on the document displayed on the target display screen when the two display screens satisfy a page turning condition according to the rotation direction and the posture of the first display screen and the second display screen at a relative position. Because the folding screen terminal can automatically execute page turning operation on the document displayed in the target display screen according to the posture of the display screen, page turning can be realized without executing sliding operation or clicking operation on the display screen by a user, and the page turning reliability is better.
