All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In order to better understand the dual-screen switching method disclosed by the embodiment of the present invention, a mobile terminal suitable for the embodiment of the present invention is described first. The mobile terminal described in the embodiment of the present invention may include any device having two display screens and communication and storage functions, for example: smart devices such as tablet computers and mobile phones, the mobile terminal can be installed with an operating system including: the mobile terminal may further install a plurality of application programs based on the installed operating system, where the application programs may be system applications pre-installed before the mobile terminal leaves a factory, such as mailbox applications, setup applications, music applications, browser applications, photographing applications, and the like, or may also be third-party applications installed by the user, such as QQ applications, wechat applications, pay applications, microblog applications, and the like, and specific details are not limited herein.
For convenience of understanding, a specific flow in the embodiment of the present invention is described below, and referring to fig. 1, an embodiment of a dual-screen switching method in the embodiment of the present invention includes:
101. acquiring the distance between a first screen and a first placed object;
in this embodiment, after the mobile terminal is started, a distance between the first screen and the first placing object may be acquired, where the mobile terminal may include the first screen and the second screen, and the first screen and the second screen may be located at front and back relative positions of the mobile terminal.
Specifically, the first screen and the second screen may be respectively located on the front side and the back side of the mobile terminal, wherein a front screen is provided on the front side (front side) of the mobile terminal. For example, the secondary screen is arranged on the back side (back side), if the first screen is located on the front side of the mobile terminal, the first screen is the main screen, the second screen is the secondary screen, and if the first screen is located on the back side of the mobile terminal, the first screen is the secondary screen, and the second screen is the main screen.
In practical application, the first screen is not limited to be the main screen or the sub-screen, that is, the obtained distance may be a distance between the main screen and the first object to be placed, or a distance between the sub-screen and the first object to be placed, and the corresponding setting may be specifically performed according to the requirement of the dual-screen switching, which is not limited herein.
In this embodiment, the first placing object is an object that supports the mobile terminal, and preferably, compared with the second screen, the first placing object may be an object that is relatively close to the first screen, for example, if the mobile terminal is placed on a desktop, at this time, the second screen is placed upward, then the first placing object is the desktop, the distance between the first screen and the desktop is obtained, and if the mobile terminal is assumed to be held by a user, at this time, the second screen faces the user, then the first placing object may be a palm of the user, and the obtained distance between the first screen and the palm is obtained.
102. Judging whether the distance is not greater than a preset threshold value, if so, executing a step 103, and if not, executing a step 104;
in this embodiment, after the distance between the first screen and the first placement object is obtained, whether the distance is not greater than a preset threshold value may be determined.
Specifically, a preset threshold may be preset in the mobile terminal to serve as a criterion for distance determination, and by comparing the distance with the preset threshold, the position state between the first screen and the first placed object may be estimated, so that the facing state between the first screen and the user may be determined, and the switching between the first screen and the second screen may be triggered when the distance satisfies the setting condition of the preset threshold.
In this embodiment, the preset threshold may be set by the user, or may be set by the mobile terminal based on data statistics of the server, or may be set by the mobile terminal before shipping, which is not limited herein.
103. Switching the content of the first screen to a second screen;
in this embodiment, if the distance is not greater than the preset threshold, the content of the first screen may be switched to the second screen.
Specifically, under the condition that the distance between the first screen and the first placement object is not greater than the preset threshold, which indicates that the display of the first screen on the mobile terminal is not convenient for the user to view, the content of the first screen can be switched to the second screen, so that the content of the first screen can be displayed on the second screen. For example, if a user holds the mobile terminal by hand, if the distance between the first screen and the palm center of the user is not greater than a preset threshold, it indicates that the second screen faces the user, the content of the first screen cannot be effectively displayed to the user or the user performs corresponding convenient operation, and the content of the first screen can be switched to the second screen under the condition that the distance satisfies the switching condition between the first screen and the second screen, so that the user can freely select the screen.
104. Other flows are performed.
In this embodiment, if it is determined that the distance between the first screen and the first placement object is greater than the preset threshold, which means that the content of the first screen is not required to be switched to only the second screen, other operations may not be performed, so that the mobile terminal maintains the current screen display state. In practical applications, other operations may also be performed, and are not limited herein.
In this embodiment, through the adoption of the distance perception mechanism, when the distance between the first screen and the first placed object is not greater than the preset threshold value, the content of the first screen is switched to the second screen, so that the convenience of user operation is improved, the triggering through the physical keys is not needed, the hardware development cost is favorably reduced, and the service life of the physical keys is prolonged.
It can be understood that, in practical applications, in order to avoid causing unnecessary dual-screen switching, a limitation may be imposed on the prerequisite of dual-screen switching, please refer to fig. 2, and another embodiment of the dual-screen switching method in the embodiment of the present invention includes:
201. detecting whether the first screen is in a bright screen state, if so, executing step 202, and if not, executing step 206;
in this embodiment, the condition that the first screen may need to be used may be determined through the screen-up state of the first screen, and then, after the mobile terminal is started, whether the first screen is in the screen-up state may be detected.
Specifically, the display screen of the mobile terminal may be divided into a bright screen state and a black screen state, where the bright screen state and the black screen state are two completely opposite display states. In a general case, since the display screen is in a bright screen state during the use of the mobile terminal by the user, whether the first screen is expected to be used or not can be estimated through the detection of the bright screen state.
It can be understood that, in this embodiment, the first screen of the mobile terminal is in a bright screen state, which is not equivalent to that the mobile terminal is in a non-locked state, for example, if the mobile terminal is provided with an unlocking password, when a user inputs the unlocking password in the mobile terminal, the screen of the mobile terminal may be in a bright screen state, but in a case that the unlocking password is not completely input or is input incorrectly, the mobile terminal is still in a locked state.
202. Detecting whether the orientation of the first screen meets a preset condition, if so, executing step 203, and if not, executing step 206;
in this embodiment, if it is detected that the first screen is in the bright screen state, it may be further detected whether the orientation of the first screen meets the preset condition.
In this embodiment, a specific manner of detecting whether the orientation of the first screen meets the preset condition may be:
detecting whether the first screen is placed downwards by using a gravity sensor, and if so, determining that the orientation of the first screen meets a preset condition; or the like, or, alternatively,
whether the first screen faces the first placed object or not is detected by the camera, and if yes, the orientation of the first screen is determined to meet a preset condition.
Specifically, taking a mobile terminal held by a user as an example, if the first screen faces the user, the user can freely view the content of the first screen or perform corresponding operations on the first mobile terminal, the switching operation of the first screen may not be performed even when the first screen is in a bright screen state, and if the first screen does not face the user, the user cannot view the content of the first screen and cannot perform related operations, and the switching operation of the first screen may be performed when the first screen is in the bright screen state. Based on the above description, on one hand, whether the first screen is placed downwards, that is, whether the gravity direction points to the first screen, may be detected through the gravity sensor, and if the gravity direction points to the first screen, it is described that the first screen is placed downwards and the first screen does not face the user, otherwise, it is described that the first screen does not face the user. On the other hand, whether the first screen faces the first placing object or not can be detected through the camera, wherein the camera and the first screen can be located on the same physical surface of the mobile terminal, and when the camera is in an open state, if the camera area is detected to have the first placing object, the first screen can be considered to face the first placing object but not face the user, otherwise, the first screen is considered not to face the first placing object but faces the user.
It is understood that the present embodiment has described only the specific manner of detecting whether the orientation of the first screen satisfies the preset condition in the above two examples, and in practical applications, other manners may also be adopted as long as it can be determined whether the orientation of the first screen satisfies the preset condition, and the specific manner is not limited herein.
It should be noted that, in this embodiment, step 201 and step 202 may also be executed at the same time, or step 202 may be executed first and then step 201 is executed, which is not limited herein.
Step 203 in this embodiment is the same as step 101 in the embodiment shown in fig. 1, and is not described here again.
204. Judging whether the distance is not greater than a preset threshold value, if so, executing a step 205, and if not, executing a step 206;
206. Other flows are performed.
In this embodiment, if it is detected that the first screen is not in the bright screen state, which means that there is no need to switch the content of the first screen to the second screen, no other operation may be performed, so that the mobile terminal maintains the current screen display state. In practical applications, other operations may also be performed, and are not limited herein.
In this embodiment, if it is detected that the orientation of the first screen does not satisfy the preset condition, which means that there is no need to switch the content of the first screen to the second screen, no other operation may be performed, so that the mobile terminal maintains the current screen display state. In practical applications, other operations may also be performed, and are not limited herein.
In this embodiment, if it is determined that the distance between the first screen and the first placement object is greater than the preset threshold, which means that there is no need to switch the content of the first screen to the second screen, other operations may not be performed, so that the mobile terminal maintains the current screen display state. In practical applications, other operations may also be performed, and are not limited herein.
It can be understood that, in this embodiment, when the orientation of the first screen does not satisfy the preset condition, it may be stated that the orientation of the second screen satisfies the preset condition in a reverse manner, and since the first screen is defined as a display screen of a side of the mobile terminal that does not face the user in this embodiment, if the orientation of the first screen does not satisfy the preset condition, the second screen may be correspondingly detected, and at this time, the second screen is the first screen.
Based on the beneficial effects of the embodiment shown in fig. 1, in this embodiment, the switching condition from the content of the first screen to the second screen is limited, that is, under the condition that the distance between the first screen and the first placed object is not greater than the preset threshold, the first screen should be in a bright screen state and not face the user, so that whether the first screen needs to be switched can be estimated, and the phenomenon that the user experience is not good due to the fact that the screen is switched when the user does not need to switch the screen is avoided.
On the basis of the embodiment shown in fig. 2, if the first screen and the second screen are fixed display screens of the mobile terminal, that is, have specific physical locations, that is, the main screen or the sub screen described in step 101 in the embodiment shown in fig. 1, in an actual using process, when the first screen does not satisfy the switching operation, the second screen may be correspondingly detected to realize that the content of the second screen is switched to the first screen, which is described by taking the first screen as the main screen and the second screen as the sub screen as an example, please refer to fig. 3, where another embodiment of the dual-screen switching method in the embodiment of the present invention includes:

based on the contents described in steps 201 to 205 in the embodiment shown in fig. 2, the contents of steps 301 to 305 in this embodiment are the same except that the first screen is defined as the main screen, and are not repeated here.
306. Detecting whether the auxiliary screen is in a bright screen state, if so, executing a step 307, and if not, executing a step 310;
in this embodiment, if the orientation of the main screen does not satisfy the preset condition, it is indicated that the main screen faces the user, and the sub screen does not face the user, and it may be detected whether the sub screen is in a bright screen state.
307. Acquiring the distance between the auxiliary screen and a first placed object;

in this embodiment, if the orientation of the main screen does not satisfy the preset condition, it is indicated that the main screen faces the user, and the sub screen does not face the user, and it may be detected whether the sub screen is in a bright screen state.
Based on the contents described in steps 201 to 205 in the embodiment shown in fig. 2, in steps 306 to 308 in this embodiment, the contents of the other parts are the same except that the first screen is defined as the main screen, the second screen is defined as the sub-screen, and the orientation of the second screen satisfies the preset condition, and are not repeated here.
310. Other flows are performed.
In this embodiment, if the orientation of the main screen is not in the bright screen state when the preset condition is met, which means that there is no need to switch the content of the main screen to the sub-screen, other operations may not be performed, so that the mobile terminal maintains the current screen display state. In practical applications, other operations may also be performed, and are not limited herein.
In this embodiment, if it is determined that the distance between the main screen and the first placement object is greater than the preset threshold, which means that there is no need to switch the content of the main screen to the sub-screen, other operations may not be performed, so that the mobile terminal maintains the current screen display state. In practical applications, other operations may also be performed, and are not limited herein.

403. If the first screen is positioned on the front side of the mobile terminal, acquiring a statistical distance between the first screen and a first placed object, which is acquired by a distance sensor at a preset time interval, within a preset time length;
in this embodiment, when it is detected that the first screen is in a bright screen state and the orientation of the first screen meets the preset condition, if the first screen is located on the front side of the mobile terminal, the statistical distance between the first screen and the first placed object, which is acquired by the distance sensor at preset time intervals, may be obtained within a preset time period.
Specifically, it can set up in advance to predetermine length of time and predetermine the time interval, in order to acquire effectual statistics distance, and carry out effectual two-screen switching operation to mobile terminal, in practical application, when first screen is located mobile terminal's front, in order to be favorable to acquiring the statistics distance between first screen and the first thing of placing, can be equipped with distance sensor in mobile terminal's front, thereby when first screen is in bright screen state and its orientation satisfies the preset condition, can be in predetermineeing for a long time, utilize distance sensor to gather the statistics distance between first screen and the first thing of placing with predetermineeing the time interval, and can acquire the statistics distance after gathering the end. For example, the statistical distance between the first screen and the first placed object is collected at a preset time interval of 0.01 second within a preset time period of 1 second, whereby 10 statistical distances can be obtained.
Specifically, the distance sensor may estimate the distance between the first screen and the first placed object by emitting a particularly short light pulse and acquiring the measured time from the emission of this light pulse to the reflection of this light pulse by the first placed object, and then by measuring the time interval.
It should be noted that, the preset duration and the preset time interval in this embodiment may be set by a user, or may be set by the mobile terminal based on data statistics of the server, or may be set by the mobile terminal before shipping, which is not limited herein.
