Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

First embodiment

The first embodiment of the invention provides a double-sided screen switching method, which can be applied to a terminal with two display screens to realize effective switching of the two display screens.

Here, the terminal described above may be a fixed terminal having a display screen, or may be a mobile terminal having a display screen.

The above-mentioned fixed terminal may be a computer, and the above-mentioned mobile terminal includes but is not limited to a mobile phone, a notebook computer, a camera, a PDA, a PAD, a PMP, a navigation device, and the like. The terminal can be connected to the internet, wherein the connection mode can be through a mobile internet network provided by an operator, and can also be through accessing a wireless access point to perform network connection.

Here, if the mobile terminal has an operating system, the operating system may be UNIX, Linux, Windows, Android (Android), Windows Phone, or the like.

The type, shape, size, and the like of the display screen on the terminal are not limited, and the display screen on the terminal may be a liquid crystal display screen, for example.

In the first embodiment of the present invention, the display screen described above is used to provide a human-computer interaction interface for a user. As shown in fig. 3A, the first display screen is located on the front surface of the mobile terminal, and the first display screen can be used as the main display screen of the mobile terminal. As shown in fig. 3B, the second display screen is located on the back of the mobile terminal, and the first display screen and the second display screen are display screens with the same size, so that the same display effect can be achieved, and the display position is the same as that of the first display screen. As shown in fig. 3C, the second display screen is located on the back of the mobile terminal, the size of the second display screen is smaller than that of the first display screen, and the second display screen is used as a secondary display screen.

Fig. 4 is a flowchart of a first embodiment of a method for switching a dual-sided screen according to an embodiment of the present invention, as shown in fig. 4, the method includes:

step 401: recording the brightness parameter of the first display screen when the first display screen works; and acquiring the state parameters of the terminal when the first display screen works.

Here, the state parameter is used to indicate a position state or a grip state of the terminal. In practical implementation, the brightness parameter of the first display screen and the state parameter can be recorded by the mobile terminal with the double-sided screen.

Step 402: and acquiring the state parameters of the terminal at the current moment.

Here, the terminal is continuously in a state when the first display screen is operated, and whether the user performs a screen flipping operation on the terminal is determined by monitoring a state parameter of the terminal in real time.

Step 403: and generating a switching instruction when the state parameter of the first display screen during working and the state parameter of the current moment are determined to meet the switching condition.

In an optional implementation manner, the terminal further includes: a gravity sensor; the state parameters comprise Z-direction values output by the gravity sensor. Accordingly, the handover conditions include: when the first display screen works, the Z-direction numerical value output by the gravity sensor is greater than 0, and the Z-direction numerical value output by the gravity sensor at the current moment is less than 0; or the Z-direction numerical value output by the gravity sensor is smaller than 0 when the first display screen works, and the Z-direction numerical value output by the gravity sensor at the current moment is larger than 0.

It can be understood that the attitude parameters of the terminal can be detected by the gravity sensor, and the attitude parameters can be used to indicate the attitude of the terminal, such as: the terminal is placed horizontally, obliquely, etc. The gravity sensor detects the posture of the terminal and outputs three-dimensional coordinate values including an X-axis value, a Y-axis value and a Z-axis value, and when the terminal is turned, the Y-axis is unchanged, and the directions of the X-axis and the Z-axis are changed. And the Z-axis numerical value can reflect the posture of the terminal most, the Z-axis numerical value detected by the gravity sensor is larger than 0 when the front side of the terminal faces upwards, and the Z-axis numerical value detected by the gravity sensor is smaller than 0 when the back side of the terminal faces upwards. For example, when the terminal is placed on a desktop with the front side facing up, the three-dimensional coordinate values output by the gravity sensor are X ═ 0.7, Y ═ 0.7, and Z ═ 10, respectively; when the back of the terminal is placed on the desktop upwards, the three-dimensional coordinate values output by the gravity sensor are respectively-0.69 for X, 0.71 for Y and-10 for Z. Therefore, the embodiment of the invention takes the Z-axis numerical value output by the gravity sensor as the main judgment basis for terminal turnover.

In actual implementation, when a first display screen and a second display screen of the terminal are both in a closed state, monitoring state parameters of the terminal in real time; when the state parameters of the terminal are changed, if the Z-direction numerical value output by the gravity sensor at the current moment is less than 0, controlling a first display screen to be on; and if the Z-direction numerical value output by the gravity sensor at the current moment is greater than 0, controlling the second display screen to light. For example, a change in a state parameter of the terminal may be detected by a gravity sensor or an acceleration sensor, and the change is caused by the user effectively touching the mobile terminal and does not respond if it is unintentionally touched.

In another optional implementation, the terminal further includes: the first distance sensor is positioned on one side of the first display screen, and the second distance sensor is positioned on one side of the second display screen; the state parameters include: the first distance between the first display screen and the external obstacle is detected by the first distance sensor, and the second distance between the second display screen and the external obstacle is detected by the second distance sensor. Correspondingly, the preset switching conditions include: the first distance at the current moment is smaller than a first distance threshold value, and the second distance at the current moment is larger than a second distance threshold value; the first distance threshold is less than the second distance threshold.

It can be understood that when the terminal is held, the external obstacles are mostly the user's hand, face and other body parts that often operate the mobile phone. For example, the palm of the hand of the user is close to or even touches the back of the mobile phone, and the first display screen on the front of the mobile phone is the display screen being used by the user. After the user turns over the mobile phone, the palm of the hand of the user is close to or even contacts the front side of the mobile phone, at the moment, the second display screen on the back side of the mobile phone is the display screen being used by the user, and the first display screen needs to be closed and the second display screen needs to be opened. Therefore, the distance sensor can be arranged at a place which is frequently contacted by the user according to the holding mode of the user, the holding mode is determined by detecting the distance between the screen and the hand, and the screen switching control is carried out according to the holding mode.

Here, the processor of the terminal may determine the state parameter when the first display screen operates and the state parameter at the current time, and generate the switching instruction when the state parameter satisfies the switching condition.

Step 404: and controlling the first display screen to be closed according to the switching instruction, and controlling the second display screen to be bright according to the brightness parameter of the first display screen.

Here, the processor of the terminal may control the first display screen to be turned off according to the generated switching instruction, and control the second display screen to be turned on according to the brightness parameter of the first display screen.

In actual implementation, when the second display screen is in a screen locking state, controlling the second display screen to be bright according to the switching instruction, wherein the bright screen parameter is the bright screen parameter of the first display screen, and the user performs unlocking operation on the second display screen; when the second display screen is in a power-saving display state (the screen can be directly lightened without unlocking), the second display screen is controlled to be lightened by the lightening parameter of the first display screen according to the switching instruction.

In this embodiment of the present invention, any one of steps 401 to 404 may be executed by a processor of the dual-screen terminal.

In order to further embody the object of the present invention, the above-mentioned scheme is further exemplified on the basis of the first embodiment of the present invention.

Second embodiment

Fig. 5 is a flowchart of a second embodiment of a method for switching a dual-sided screen according to an embodiment of the present invention, where as shown in fig. 5, the flowchart includes:

step 501: recording the brightness parameter of the first display screen when the first display screen works; and acquiring the state parameters of the terminal when the first display screen works.

In this step, the state parameter of the terminal when the first display screen works includes a first Z-direction value, and the first Z-direction value is a Z-direction value output by the gravity sensor when the first display screen works.

Step 502: and acquiring the state parameters of the terminal at the current moment.

The state parameters of the terminal at the current moment also comprise holding information, and the holding information is first kind of holding information or second kind of holding information; the terminal further includes: a first side and a second side; wherein,

the first type of holding information comprises M contact positions formed on the first side when the terminal is held by a single hand; the second type of holding information comprises M contact positions formed on the second side surface when the terminal is held by a single hand; m is an integer greater than 2; correspondingly, the preset switching condition further includes: the holding information of the first display screen during working is first-type holding information, and the holding information at the current moment is second-type holding information; or the holding information of the first display screen during working is the second type of holding information, and the holding information at the current moment is the first type of holding information.

The 1 st contact position 701, the 2 nd contact position 702, the 3 rd contact position 703 and the 4 th contact position are formed by pressing the left side 601 by the little finger, the ring finger, the middle finger and the index finger of the right hand respectively, and the 5 th contact position 705 is formed by pressing the right side 602 of the mobile phone by the root of the right palm.

Therefore, the state parameters obtained in this step specifically include: acquiring a Z-direction numerical value output by a gravity sensor at the current moment; p contact positions formed on the first side face when the terminal is held by a single hand and Q contact positions formed on the second side face are obtained, wherein P and Q are positive integers.

Here, the handover conditions include: the state parameter when the first display screen works and the state parameter at the current moment meet the first switching sub-condition and the second switching sub-condition.

Wherein the first switching sub-condition comprises: when the first display screen works, the Z-direction numerical value output by the gravity sensor is greater than 0, and the Z-direction numerical value output by the gravity sensor at the current moment is less than 0; or the Z-direction numerical value output by the gravity sensor is smaller than 0 when the first display screen works, and the Z-direction numerical value output by the gravity sensor at the current moment is larger than 0.

Specifically, the first switching sub-condition is as follows: the first Z-direction value is less than 0 and the second Z-direction value is greater than 0. When the Z-direction numerical value is subjected to symbol exchange, the terminal is turned over, and the terminal needs to execute screen switching operation.

As can be seen from fig. 8, the second display is operated when the terminal is held in the right hand, resulting in 4 smaller contact positions on the second side (i.e. the right side) and 1 larger contact position on the first side (i.e. the left side).

In this step, the holding information specifically includes: p contact locations are formed on the first side of the terminal when the terminal is held in one hand, and Q contact locations are formed on the second side of the terminal when the terminal is held in one hand. Therefore, when P is greater than 2, the grip information is determined to be the first type of grip information, and when Q is greater than 2, the grip information is determined to be the second type of grip information.

Specifically, when the terminal is held by the right hand, the second switching sub-condition includes: when the first display screen works, the number P of contact positions on the first side surface is more than 2, and the number Q of contact positions on the second side surface at the current moment is more than 2; when the left hand holds the terminal, the second switching sub-condition comprises: when the first display screen works, the number Q of the contact positions on the second side surface is larger than 2, and the number P of the contact positions on the first side surface at the current moment is larger than 2.

In practical implementation, when the mobile phone is operated by the holding gesture shown in fig. 6, the palm is close to the second display screen and the face or other body parts are far away from the first display screen when the first display screen is working, so the first distance threshold may be 2 cm or 1 cm, the second distance threshold may be 20 cm or 40 cm, and the second distance threshold should be much larger than the first distance threshold.

Step 902: and acquiring a first distance output by a first sensor at the current moment of the terminal and a second distance output by a second sensor.

Step 903: and judging whether the first distance and the second distance at the current moment meet the switching condition, if so, executing the step 904, otherwise, returning to the step 902.

Here, the switching condition is that the first distance is smaller than the first distance threshold value and the second distance is larger than the second distance threshold value at the present time. The switching condition is used to determine the state of the terminal at the current time, for example: when the mobile phone is held by the holding gesture shown in fig. 6, the mobile phone is turned over and then continues to be held by the holding gesture shown in fig. 6, or the first display screen is contacted with an external support after the mobile phone is turned over; if the states are the same, the screen switching operation is required at the current moment.
