This application claims the priority of the Chinese Patent Application filed on January 20, 2017, the Chinese Patent Office, Application No. 201710045481.1, entitled "A Method and Apparatus for Avoiding Double Screen Mis-Switching Through TP Sensing", the entire contents of which is incorporated herein by reference. This is incorporated herein by reference.

Technical field

The present application relates to the field of electronic device technologies, and in particular, to a screen switching method for a dual-screen electronic device and a dual-screen electronic device.

Background technique

With the development of electronic device technology, dual-screen display is increasingly used in various types of electronic devices, such as mobile phones, tablets, personal digital assistants (PDAs) and the like. The two screens of the dual-screen electronic device are respectively located on the front and back sides of the dual-screen electronic device, and the two screens can be independently displayed. That is, when the screen A of the dual screen electronic device is displayed, the screen B of the dual screen electronic device is turned off; when the screen B of the dual screen electronic device is displayed, the screen A is turned off. Dual-screen electronic devices can meet the different needs of users and bring a better user experience.

How to accurately switch between the two screens of a dual-screen electronic device according to user needs is an urgent problem to be solved. Generally, a dual-screen electronic device can sense the movement of an electronic device through a gravity sensor or through a gyroscope to determine whether it needs to perform screen switching. However, this kind of screen switching method is less accurate in some scenarios, which may cause mis-switching of the screen. Taking a dual-screen electronic device as a mobile phone, when the user is using the screen A, if the user needs to flip the screen A downward, to prevent others from seeing the content on the screen, or when the user browses the content displayed on the screen A, adjust the user. The posture will cause a large change in the position and angle of the dual-screen electronic device, causing the gravity sensor or the gyroscope to misjudge the action of flipping the mobile phone or adjusting the posture as the action of switching the screen, and using the mobile phone for display. The screen is switched from screen A to screen B, which in turn causes a false switch of the screen. The scene in which the user flips the mobile phone in order to prevent others from seeing the content on the screen, thereby causing the screen to switch incorrectly, can be as shown in FIG. 1 .

In summary, there is a need for a screen switching method for a highly accurate dual-screen electronic device.

Summary of the invention

The embodiment of the present application provides a screen switching method for a dual-screen electronic device and a dual-screen electronic device, which are used to improve the accuracy of the dual-screen electronic device when performing screen switching.

In a first aspect, an embodiment of the present application provides a screen switching method for a dual-screen electronic device, where the method includes the following steps:

The dual-screen electronic device detects the first touch area and the second touch area, and performs screen switching when the first touch area is greater than the second touch area.

The first touch area is used to indicate the contact area of the user with the first screen of the dual-screen electronic device, and the second touch area is used to indicate the contact area between the user and the second screen of the dual-screen electronic device. The first screen is The currently lit screen in the dual screen electronic device, and the second screen is the currently unlit screen in the dual screen electronic device.

It should be noted that, in the present application, the first screen and the second screen can be independently displayed. That is, when the first screen When the display is performed, the second screen is turned off; when the second screen is displayed, the first screen is turned off.

Generally, when the user operates the electronic device, the contact area with the screen being displayed in the electronic device is small, and the contact area with the reverse side of the screen being displayed (or the screen not used for display) is large. Therefore, the two-screen electronic device can determine which screen the user desires to display by judging which screen the user has with which screen of the dual-screen electronic device is small.

In the screen switching method of the dual-screen electronic device provided by the first aspect, the dual-screen electronic device detects the first touch area and the second touch area, and can compare the first touch area and the second touch area to determine Whether you need to switch screens. Since the user does not touch the screen to the desired display screen, that is, the user's finger (or palm) and the desired operation, regardless of the user's various operations such as adjusting the posture, flipping the mobile phone, or switching the screen. The touch area of the displayed screen is larger than the touch area of the other screen. Therefore, in the screen switching method of the dual-screen electronic device provided by the first aspect, the dual-screen electronic device determines whether a screen switching is required by comparing the first touch area and the second touch area, and the prior art passes gravity. Compared with the scheme in which the sensor or the gyroscope determines whether or not to perform screen switching, it is possible to make an accurate judgment on whether or not to perform screen switching in the case where the user is in various postures and various scenes.

For example, when the user is using the screen A, if the user needs to flip the screen A downward to prevent others from seeing the content on the screen, the user touches the first touch area of the screen A after the action of flipping the mobile phone. Compared with the second touch area of the user and the screen B, the screen switching method of the dual-screen electronic device provided by the first aspect does not misjudge the action of the user flipping the mobile phone as the action of switching the screen as in the prior art. Instead, it will accurately determine that the dual-screen electronic device does not need to switch screens.

For another example, when the user is using the screen A, if the user adjusts his or her posture while browsing the content displayed on the screen A, since the manner in which the user operates the mobile phone does not change, the first touch area is still smaller than the second touch. Controlling the area, then the screen switching method of the dual-screen electronic device provided by the first aspect does not mistake the user's action of adjusting his posture as the action of switching the screen as in the prior art, but accurately determines the dual screen. The electronic device does not need to switch screens.

In a possible design, the dual-screen electronic device detects the first touch area and the second touch area, which can be implemented by: the dual-screen electronic device detecting the quantity of the first node capacitor on the first screen, and The number of the second node capacitors on the two screens, and determining the first touch area according to the number of the first node capacitors, and determining the second touch area according to the number of the second node capacitors.

The first node capacitance is a node capacitance in which a sense current changes in a plurality of node capacitances of the first screen, and the second node capacitance is a node capacitance in which a sense current changes in a plurality of node capacitances of the second screen.

With the above solution, an implementation for detecting the first touch area and the second touch area is provided.

In a possible design, when the dual-screen electronic device detects the first touch area and the second touch area, specifically: when the gravity sensor in the dual-screen electronic device indicates the tilt angle of the dual-screen electronic device relative to the horizontal plane When the first preset angle is greater than the first preset angle, the dual-screen electronic device detects the first touch area and the second touch area.

The dual-screen electronic device can sense its own movement mode through the gravity sensor, and then initially determine whether the screen switching is needed: the gravity sensor is internally provided with a crystal, and when the gravity acceleration of the dual-screen electronic device changes, the crystal is deformed. The gravity sensor converts the deformation of the crystal into a voltage signal, which reflects the deformation of the crystal, thereby reflecting the change in the gravitational acceleration of the dual-screen electronic device. By analyzing the change of gravity acceleration, the dual-screen electronic device can know its own movement mode (such as the tilt angle of the dual-screen electronic device with respect to the horizontal plane, etc.), and then determine whether it is necessary to perform screen switching by analyzing its own movement mode. For example, when the gravity sensor indicates that the angle of the dual-screen electronic device flipped relative to the horizontal plane is greater than the first predetermined angle by 90°, the dual-screen electronic device can pass gravity The indication of the sensor initially determines that a screen switch is required. Then, the dual-screen electronic device detects the first touch area and the second touch area, and finally determines to perform screen switching on the dual-screen electronic device when the first touch area is greater than the second touch area.

With the above solution, when the dual-screen electronic device initially determines that the screen switching needs to be performed by the indication of the gravity sensor, the first touch area and the second touch area are finally detected to determine whether to perform the screen switching action. When the screen is switched by the indication of the gravity sensor and the first touch area is larger than the second touch area, the screen switching of the dual-screen electronic device can improve the accuracy of the screen switching method.

In a possible design, the dual-screen electronic device detects the first touch area and the second touch area, and specifically includes: when the gyroscope in the dual-screen electronic device indicates that the rotational angular velocity of the dual-screen electronic device is greater than the preset angular velocity, Or when the rotation angle of the dual-screen electronic device is greater than the second preset angle, the dual-screen electronic device detects the first touch area and the second touch area. The gyroscope is used to indicate the rotational angular velocity or the rotational angle of the dual-screen electronic device.

The dual-screen electronic device can sense its own movement mode through the gyroscope, and then initially determine whether screen switching is required: when the gyroscope (such as the silicon microgyroscope) is in normal operation, if the dual-screen electronic device rotates, the rotating motion A displacement is generated in the orthogonal direction that is proportional to the rotational angular velocity or angle of rotation of the dual-screen electronic device. The gyroscope converts this displacement into a change in capacitance. The dual-screen electronic device can know its own rotational angular velocity or rotational angle by analyzing the amount of change in capacitance. When the gyroscope indicates that the rotational angular velocity of the dual-screen electronic device is greater than the preset angular velocity, or indicates that the rotational angle of the dual-screen electronic device is greater than the second predetermined angle, the dual-screen electronic device initially determines that screen switching is required. Then, the dual-screen electronic device detects the first touch area and the second touch area, and finally determines to perform screen switching on the dual-screen electronic device when the first touch area is greater than the second touch area.

With the above solution, when the dual-screen electronic device initially determines that the screen switching is required by the indication of the gyroscope, the first touch area and the second touch area are detected to finally determine whether to perform the screen switching action. When the screen is switched by the indication of the gyroscope and the first touch area is larger than the second touch area, the screen switching of the dual-screen electronic device can improve the accuracy of the screen switching method.

In a second aspect, the present application provides a dual screen electronic device including a first screen, a second screen, and a processor.

The processor is configured to detect the first touch area and the second touch area; and perform screen switching when the first touch area is greater than the second touch area.

The first touch area is used to indicate a contact area between the user and the currently lit screen in the first screen and the second screen, and the second touch area is used to indicate that the user and the first screen and the second screen are not currently in the point. The contact area of the bright screen.

Generally, when the user operates the electronic device, the contact area with the screen being displayed in the electronic device is small, and the contact area with the reverse side of the screen being displayed (or the screen not used for display) is large. Therefore, the processor 503 can determine which screen the user desires to use for display by determining which screen of the dual screen electronic device the user has a small contact area.

In the dual-screen electronic device provided in the second aspect, the processor detects the first touch area and the second touch area, and compares the first touch area and the second touch area to determine whether screen switching is required. Since the user does not touch the screen to the desired display screen, that is, the user's finger (or palm) and the desired operation, regardless of the user's various operations such as adjusting the posture, flipping the mobile phone, or switching the screen. The touch area of the displayed screen is larger than the touch area of the other screen. Therefore, in the dual-screen electronic device provided by the second aspect, the processor determines whether a screen switching is required by comparing the first touch area and the second touch area, and the prior art uses a gravity sensor or a gyroscope. Determining whether to perform screen switching compared to the scenario where the user is in various poses and various scenarios In the case of any, it is possible to make an accurate judgment on whether or not to perform screen switching.

For example, when the user is using the screen A, if the user needs to flip the screen A downward to prevent others from seeing the content on the screen, the user touches the first touch area of the screen A after the action of flipping the mobile phone. The second touch area of the user and the screen B is smaller than the second touch area provided by the second aspect. In this case, when the dual screen electronic device provided by the second aspect is used to detect whether the screen switching is required, the user's motion of flipping the mobile phone is not misjudged as in the prior art. Switching the action of the screen, but accurately determining that the dual-screen electronic device does not need to switch screens.

For another example, when the user is using the screen A, if the user adjusts his or her posture while browsing the content displayed on the screen A, since the manner in which the user operates the mobile phone does not change, the first touch area is still smaller than the second touch. If the dual-screen electronic device provided by the second aspect is used to detect whether screen switching is required, the user does not mistake the action of adjusting the user's posture as the action of switching the screen, but is accurate. It is judged that the dual screen electronic device does not need to perform screen switching.

In one possible design, the first screen and the second screen are both screens with multi-touch functionality.

When the first screen and the second screen have multi-touch functions, the first touch area and the second touch area may be detected by the processor.

In a possible design, when detecting the first touch area and the second touch area, the method may be implemented by: detecting the first node capacitance on the currently lit screen in the first screen and the second screen. The number, and the number of second node capacitances on the currently unlit screens in the first screen and the second screen; determining the first touch area according to the number of first node capacitances, and determining the number according to the number of second node capacitances Two touch areas.

The first node capacitance is a node capacitance of a plurality of node capacitances of the currently lit screen in the first screen and the second screen, and the second node capacitance is currently not in the first screen and the second screen. A node capacitance in which a sensed current changes in a plurality of node capacitances of a bright screen.

With the above solution, an implementation manner of detecting the first touch area and the second touch area by the processor is provided.

In a possible design, the dual-screen electronic device further includes a gravity sensor, and the processor is further configured to: when the gravity sensor indicates that the tilt angle of the dual-screen electronic device relative to the horizontal plane is greater than the first preset angle, the processor detects the first touch Control area and second touch area.

The dual-screen electronic device can sense its own movement mode through the gravity sensor, and then initially determine whether the screen switching is needed: the gravity sensor is internally provided with a crystal, and when the gravity acceleration of the dual-screen electronic device changes, the crystal is deformed. The gravity sensor converts the deformation of the crystal into a voltage signal, which reflects the deformation of the crystal, thereby reflecting the change in the gravitational acceleration of the dual-screen electronic device. By collecting the voltage signal, the processor can know the movement mode of the dual-screen electronic device (such as the tilt angle of the dual-screen electronic device relative to the horizontal plane) by analyzing the change of the gravity acceleration, and then analyze the movement mode of the dual-screen electronic device. Determine if a screen switch is required. For example, when the processor determines that the angle of the dual-screen electronic device with respect to the horizontal plane is greater than the first preset angle by 90° according to the collected voltage signal, it is initially determined that the dual-screen electronic device needs to perform screen switching. Then, the processor detects the first touch area and the second touch area, and finally determines to perform screen switching on the dual-screen electronic device when the first touch area is greater than the second touch area.

According to the above solution, after the processor initially determines that the screen switching needs to be performed by the indication of the gravity sensor, the processor further determines whether to perform the screen switching action by detecting the first touch area and the second touch area. When the processor initially determines that the screen is to be switched through the indication of the gravity sensor, and the first touch area is greater than the second touch area, the processor performs screen switching on the dual-screen electronic device, thereby improving the accuracy of the screen switching method.

In one possible design, the dual screen electronic device also includes a gyroscope, and the processor is also used to indicate dual screen when the gyroscope is instructed The first touch area and the second touch area are detected when the rotational angular velocity of the electronic device is greater than the preset angular velocity or when the rotational angle of the dual-screen electronic device is greater than the second predetermined angle.

The gyroscope is used to indicate the rotational angular velocity or the rotational angle of the dual-screen electronic device.

The dual-screen electronic device can sense its own movement mode through the gyroscope, and then initially determine whether screen switching is required: when the gyroscope (such as the silicon microgyroscope) is in normal operation, if the dual-screen electronic device rotates, the rotating motion A displacement is generated in the orthogonal direction that is proportional to the rotational angular velocity of the dual-screen electronic device. The gyroscope converts this displacement into a change in capacitance. By analyzing the amount of change in capacitance, the processor can know the rotational angular velocity or angle of rotation of the dual-screen electronic device. For example, when the gyroscope indicates that the rotational angular velocity of the dual-screen electronic device is greater than the preset angular velocity, or indicates that the rotational angle of the dual-screen electronic device is greater than the second predetermined angle, the processor initially determines that the dual-screen electronic device needs to perform screen switching. Then, the processor detects the first touch area and the second touch area, and finally determines to perform screen switching on the dual-screen electronic device when the first touch area is greater than the second touch area.

With the above solution, after the processor initially determines that the screen switching needs to be performed by the indication of the gyroscope, the processor further determines whether to perform the screen switching action by detecting the first touch area and the second touch area. When the processor initially determines that the screen is to be switched through the indication of the gyroscope, and the first touch area is greater than the second touch area, the processor performs screen switching on the dual-screen electronic device, thereby improving the accuracy of the screen switching method.

detailed description

The present application relates to how a dual screen electronic device determines whether a screen switch is required. Generally, a dual-screen electronic device can sense its own movement mode through a gravity sensor or through a gyroscope to determine whether it needs to perform screen switching.

The dual-screen electronic device senses its own movement mode through the gravity sensor, and then determines whether it needs to perform screen switching. The gravity sensor in the dual-screen electronic device is internally provided with a crystal, and when the gravity acceleration of the dual-screen electronic device changes. Will cause the crystal to deform. The gravity sensor converts the deformation of the crystal into a voltage signal that reflects the deformation of the crystal, thereby reflecting the change in the gravitational acceleration of the dual-screen electronic device. Pass After analyzing the change of gravity acceleration, the moving mode of the dual-screen electronic device (such as the tilt angle of the dual-screen electronic device with respect to the horizontal plane) can be known, and then by analyzing the moving mode of the dual-screen electronic device, it can be determined whether the screen switching is needed. For example, when the angle of the dual-screen electronic device flipped relative to the horizontal plane is 180°, the dual-screen electronic device determines that it needs to perform screen switching.

The dual-screen electronic device senses its own movement mode through the gyroscope, and then determines whether it needs to switch the screen. The gyroscope (such as a silicon microgyroscope) can rotate when the electronic device rotates during normal operation. The action produces a displacement in the orthogonal direction that is proportional to the rotational angular velocity or angle of rotation of the dual-screen electronic device. The gyroscope converts this displacement into a change in capacitance. By analyzing the amount of change in capacitance, the rotational angular velocity or angle of rotation of the dual-screen electronic device can be known. For example, when the rotational angular velocity of the dual-screen electronic device is greater than a preset value, or when the rotational angle of the dual-screen electronic device is greater than a preset value, the dual-screen electronic device determines that it needs to perform screen switching.

However, this way of judging whether or not to perform screen switching may result in a judgment error in some scenarios.

For example, when the user uses the screen A of the dual-screen electronic device for display, if the user needs to turn the screen A down for some reason, the others are prevented from seeing the content on the screen A. At this time, by analyzing the voltage signal output by the gravity sensor, the dual-screen electronic device can know that it has turned 180° with respect to the horizontal plane, thereby determining that it is necessary to switch the screen to itself. In this case, the judgment result of the screen switching is different from the original intention of the user, which may cause a wrong switching of the screen.

For another example, when the user performs display using the screen A of the dual-screen electronic device, if the user browses the content displayed in the screen A, the user's posture is adjusted, for example, the posture of the standing is adjusted to the posture of lying flat. At this time, by analyzing the amount of change in the capacitance outputted by the gyroscope, the dual-screen electronic device can know that its own rotational angular velocity is greater than a preset value, thereby determining that it is necessary to perform screen switching on itself, as shown in FIG. In this case, the judgment result of the screen switching is different from the original intention of the user, which may cause a wrong switching of the screen.

In order to improve the accuracy of the screen switching of the dual-screen electronic device. The application provides a screen switching method for a dual-screen electronic device and a dual-screen electronic device. The method and the dual-screen electronic device are based on the same inventive concept.

It will be understood by those skilled in the art that the internal structure of the electronic device shown in FIG. 2 does not constitute a limitation on the electronic device, and may include more or less components than those illustrated, or combine some components, or different components. Arrangement.

The embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

Referring to FIG. 3, a screen switching method of a dual-screen electronic device provided by the present application is provided. The method can be applied to an electronic device having two screens, that is, applied to a dual screen electronic device. When the first screen of the two screens of the dual-screen electronic device is currently in the lighting state and the second screen is in the unlit state, the method shown in FIG. 3 can be used to determine whether the dual-screen electronic device needs to perform screen switching. The method comprises the following steps:

S301: The dual-screen electronic device detects the first touch area and the second touch area.

It should be noted that, in the present application, the schematic diagram of the dual-screen electronic device may be as shown in FIG. 2, but is not limited to the dual-screen electronic device shown in FIG. 2.

The first touch area is used to indicate the contact area of the user with the first screen of the dual-screen electronic device, and the second touch area is used to indicate the contact area of the user with the second screen of the dual-screen electronic device. There are two screens that the dual-screen electronic device can use for display, namely the first screen and the second screen. The first screen is a screen that is currently lit by the dual-screen electronic device, and the second screen is a screen that the dual-screen electronic device is currently not lit.

In the present application, the first screen and the second screen may be touch screens having multi-touch functions. When the first screen and the second screen have multi-touch functions, the dual-screen electronic device can detect the first touch area and the second touch area.

Taking the multi-touch function of the first screen as an example, when the user performs multi-touch or click on the first screen, multi-touch or click operation generates multiple signals, and multi-touch technology can simultaneously Multiple signals are collected and each signal is identified, so that the first screen can realize multi-touch and click of the user. Then, when the first screen has a multi-touch function, the dual-screen electronic device can detect the first touch area of the user and the first screen.

It should be noted that the type of the first screen and the type of the second screen are not limited in the embodiment of the present application. For example, the first screen may be a capacitive screen or a resistive screen, and the second screen may be a capacitive screen or a resistive screen. For example, the first screen can support multi-touch or single-touch, and the second screen can support multi-touch or single-touch. In the present application, the dual-screen electronic device only needs to enable the dual-screen electronic device to detect the first touch area enclosed by the plurality of touch points in the first screen, and enable the dual-screen electronic device to detect multiple touches in the second screen. The second touch area enclosed by the control points can be.

A pattern diagram of the first screen can be as shown in FIG. In FIG. 4, a plurality of driving channels are arranged vertically in parallel, and a plurality of sensing channels are arranged in parallel in the lateral direction. The first screen works as follows: the drive channel and the sense channel are coupled to each other to form a node capacitance at the intersection of each of the drive channel and the sense channel. When the user's finger (or palm) touches the screen, the sensing circuit of the node capacitance of the user's finger (or palm) coverage area changes, and the touch function of the first screen can be realized by detecting the amount of change. The working principle of the second screen is similar to that of the first screen, and will not be described here.

Based on the working principle of the touch screen described above, the dual-screen electronic device in S301 detects the first touch area and the second touch area, which can be implemented by: the dual-screen electronic device detecting the number of the first node capacitors on the first screen. And the number of second node capacitors on the second screen. Wherein, the first node capacitance is a node capacitance of a plurality of node capacitances of the first screen that changes in induced current, and the second node capacitance is a node capacitance of a plurality of node capacitances of the second screen that changes in induced current; the dual-screen electronic device The first touch area is determined according to the number of first node capacitances, and the second touch area is determined according to the number of second node capacitances.

As described above, when the user's finger (or palm) touches the first screen, among the plurality of node capacitances on the first screen, the node capacitance (ie, the first capacitance) covered by the user's finger (or palm) The induced current changes, and after the dual-screen electronic device detects the number of the first capacitors, the first touch area can be determined according to the number of the first capacitors. For example, the first touch area can be estimated according to the pattern of the first screen, the size of the screen, and the number of first capacitors.

Similarly, as described above, when the user's finger (or palm) touches the second screen, among the plurality of node capacitances on the second screen, the node capacitance (ie, the second) covered by the user's finger (or palm) The induced current of the capacitor changes, and after the dual-screen electronic device detects the second capacitor, the second touch area can be determined according to the number of the second capacitor. For example, the second touch area can be estimated according to the pattern of the second screen, the size of the screen, and the number of second capacitors.

It should be noted that, in the embodiment of the present application, the operations of detecting the first touch area and the second touch area in S301 may be triggered by a certain condition, such as in a dual-screen electronic device by other means (such as by a gravity sensor or a gyroscope). The device determines that the preliminary determination may need to be performed when the screen is switched, or when detecting that the dual-screen electronic device moves or rotates; or the operation of detecting the first touch area and the second touch area in S301 may be performed from time to time. That is, the dual-screen electronic device detects the first touch area and the second touch area from time to time. The execution timing of S301 is not limited in the present application.

When the dual-screen electronic device detects the first touch area and the second touch area from time to time, the dual-screen electronic device can perform the operation of comparing the first touch area and the second touch area under the trigger of a certain condition, thereby determining whether Switch the screen. For example, the dual-screen electronic device detects the first touch area and the second touch area from time to time. When the dual-screen electronic device judges that the screen switch may be required by other means (such as by gravity sensor or gyroscope), the first comparison is made. The size of the touch area and the second touch area are performed, and the screen is switched when the first touch area is larger than the second touch area.

S302: The dual-screen electronic device performs screen switching when the first touch area is greater than the second touch area.

Since the currently lit screen in the dual-screen electronic device is the first screen, the dual-screen electronic device in S302 performs the screen. The meaning of the screen switching is that when the screen for display in the dual screen electronic device is switched from the first screen to the second screen. At this time, the first screen is in an unlit state, and the second screen is in a lit state.

In addition, if the first touch area detected by the dual-screen electronic device is smaller than the second touch area, the dual-screen electronic device does not perform screen switching.

In the screen switching method of the dual-screen electronic device shown in FIG. 3, the dual-screen electronic device detects the first touch area and the second touch area, and can compare the first touch area and the second touch area to determine Whether you need to switch screens. Since the user does not touch the screen to the desired display screen, that is, the user's finger (or palm) and the desired operation, regardless of the user's various operations such as adjusting the posture, flipping the mobile phone, or switching the screen. The touch area of the displayed screen is larger than the touch area of the other screen. Therefore, in the screen switching method of the dual-screen electronic device shown in FIG. 3, the dual-screen electronic device determines whether a screen switching is required by comparing the first touch area and the second touch area, and the prior art passes gravity. Compared with the scheme in which the sensor or the gyroscope determines whether or not to perform screen switching, it is possible to make an accurate judgment on whether or not to perform screen switching in the case where the user is in various postures and various scenes.

For example, when the user is using the screen A, if the user needs to flip the screen A downward to prevent others from seeing the content on the screen, the user touches the first touch area of the screen A after the action of flipping the mobile phone. It is smaller than the second touch area of the user and the screen B. At this time, the method shown in FIG. 3 is used, and the action of the user flipping the mobile phone is not mistakenly determined as the action of switching the screen, but is accurately determined. Dual screen electronic devices do not require screen switching.

For another example, when the user is using the screen A, if the user adjusts his or her posture while browsing the content displayed on the screen A, since the manner in which the user operates the mobile phone does not change, the first touch area is still smaller than the second touch. Control the area, then adopt the method shown in FIG. 3, and do not mistake the user's action of adjusting his posture as the action of switching the screen as in the prior art, but accurately determine that the dual-screen electronic device does not need to perform screen switching. .

In addition, the specific implementation manners for detecting the first touch area and the second touch area by the dual-screen electronic device include but are not limited to the following two types:

The first

The dual-screen electronic device detects the first touch area and the second touch area when the gravity sensor in the dual-screen electronic device indicates that the tilt angle of the dual-screen electronic device relative to the horizontal plane is greater than the first predetermined angle.

According to the introduction of the gravity sensor sensing the movement mode of the dual-screen electronic device, when the gravity sensor indicates that the tilt angle of the dual-screen electronic device relative to the horizontal plane is greater than the first preset angle, the dual-screen electronic device can be initially indicated by the gravity sensor. It is judged that a screen switch is required. Therefore, in the first implementation manner, when the dual-screen electronic device initially determines that the screen switching is required by the indication of the gravity sensor, the first touch area and the second touch area are detected to finally determine whether to perform the screen switching action. . When the screen is switched by the indication of the gravity sensor and the first touch area is larger than the second touch area, the screen switching of the dual-screen electronic device can improve the accuracy of the screen switching method.

Second

When the gyroscope in the dual-screen electronic device indicates that the rotational angular velocity of the dual-screen electronic device is greater than the preset angular velocity, or indicates that the rotational angle of the dual-screen electronic device is greater than the second predetermined angle, the dual-screen electronic device detects the first touched area and The second touch area.

According to the introduction of the gyroscope sensing the movement mode of the dual-screen electronic device, when the gyroscope in the dual-screen electronic device indicates that the rotational angular velocity of the dual-screen electronic device is greater than the preset angular velocity, or indicates that the rotation angle of the dual-screen electronic device is greater than the first When the preset angle is two, the dual-screen electronic device can initially judge that the screen needs to be switched through the indication of the gyroscope. Therefore, the second implementation manner can be used to determine whether to perform the screen switching action by detecting the first touch area and the second touch area when the dual-screen electronic device initially determines that the screen needs to be switched through the indication of the gyroscope. When the screen is switched by the indication of the gyroscope and the first touch area is larger than the second touch area, the screen switching of the dual-screen electronic device can improve the accuracy of the screen switching method.

It should be noted that the first preset angle in the present application may be the same as or different from the second preset angle. The specific values of the first preset angle and the second preset angle are not limited in this application.

When the gravity sensor indicates that the tilt angle of the dual-screen electronic device relative to the horizontal plane is greater than the first preset angle, it means that the dual-screen electronic device initially determines that screen switching is required.

The first preset angle may be preset, for example, the first preset angle is 90°.

2. The dual-screen electronic device detects the first touch area and the second touch area.

The first touch area is used to indicate the contact area of the user with the first screen of the dual-screen electronic device, and the second touch area is used to indicate the contact area between the user and the second screen of the dual-screen electronic device. The first screen is The screen on which the dual-screen electronic device is currently lit, and the second screen is the screen on which the dual-screen electronic device is currently not lit.

3. The dual-screen electronic device determines whether the first touch area is greater than the second touch area. If yes, step 4 is performed, and if not, step 5 is performed.

4, dual-screen electronic devices for screen switching.

The dual screen electronic device performs screen switching, that is, the first screen is turned off and the second screen is lit. When the first touch area is larger than the second touch area, the contact area of the user with the first screen is greater than the contact area between the user and the second screen. In this case, according to the behavior of the user using the electronic device, the user currently desires to perform. The displayed screen is the second screen, so it is necessary to perform screen switching on the dual-screen electronic device at this time.

5. The dual-screen electronic device remains on the first screen without switching.

When the first touch area is smaller than the second touch area, the contact area between the user and the first screen is smaller than the contact area between the user and the second screen. In this case, according to the behavior of the user using the electronic device, the user currently desires to perform. The displayed screen is the first screen, so there is no need to perform screen switching on the dual-screen electronic device at this time, and the dual-screen electronic device remains on the first screen without switching.
