Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include, for example, "one or more" such forms of expression, unless the context clearly indicates to the contrary. It should also be understood that in embodiments of the present application, "one or more" refers to one or more than two (including two); "and/or", describes an association relationship of the association object, indicating that three relationships may exist; for example, a and/or B may represent: a alone, a and B together, and B alone, wherein A, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship.

Reference in the specification to "one embodiment" or "some embodiments" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise.

The plurality of the embodiments of the present application refers to greater than or equal to two. It should be noted that, in the description of the embodiments of the present application, the terms "first," "second," and the like are used for distinguishing between the descriptions and not necessarily for indicating or implying a relative importance, or alternatively, for indicating or implying a sequential order.

Furthermore, various aspects or features of the present application may be implemented as a method, apparatus, or article of manufacture using standard programming and/or engineering techniques. The term "article of manufacture" as used in the embodiments of the present application encompasses a computer program accessible from any computer-readable device, carrier, or media. For example, computer-readable media can include, but are not limited to, magnetic storage devices (e.g., hard disk, floppy disk, or magnetic strips, etc.), optical disks (e.g., compact disk, CD, digital versatile disk, digital versatile disc, DVD, etc.), smart cards, and flash memory devices (e.g., erasable programmable read-only memory, EPROM), cards, sticks, or key drives, etc. Additionally, various storage media described herein can represent one or more devices and/or other machine-readable media for storing information. The term "machine-readable medium" can include, without being limited to, wireless channels and various other media capable of storing, containing, and/or carrying instruction(s) and/or data.

With the development of internet technology, the screen projection technology is widely applied. The screen projection refers to projecting the interface content displayed on the first electronic device into the second electronic device, so that the second electronic device can synchronously display the interface content displayed by the first electronic device. The interface content of the equipment with smaller display screen (such as a mobile phone and a tablet personal computer) can be projected onto the large-screen display equipment (such as a television and a vehicle-mounted multimedia display screen) through the screen projection technology, so that a better watching effect is achieved, and a user can conveniently operate by using the operation equipment of the large-screen equipment.

It will be appreciated that before the first electronic device is screen-cast to the second electronic device, the first electronic device needs to establish a connection with the second electronic device, the user typically establishes a cooperative connection with the first electronic device by near field communication (Near Field Communication, NFC) on a touch pad located on the second electronic device, or close to a keyboard, and then screen-casts a window of the first electronic device onto an interface of the second electronic device.

In the following, a first electronic device is taken as a mobile phone, a second electronic device is taken as a notebook computer, and how to establish cooperative connection between the first electronic device and the second electronic device and how to screen a window of the first electronic device on an interface of the second electronic device in the related art is described.

For example, fig. 1 shows an interface schematic diagram of a first electronic device and a second electronic device in the related art to establish a cooperative connection. As shown in fig. 1 (a), before the notebook 110 and the mobile phone 120 establish a cooperative connection, the notebook 110 needs to click a "near found" button in a computer management home to trigger, while the bluetooth connection of the mobile phone 120 is in an open state, when the notebook 110 finds the mobile phone 120, a popup window appears on the display screen 1101 of the notebook, the popup window 1102 displays "whether to establish a connection with the first electronic device", and the user can select an "allow" button or a "reject" button on the popup window 1102 of the notebook according to actual requirements. When the user clicks the "allow" button, the connection is established between the notebook computer 110 and the mobile phone 120, and then the interface 1201 of the mobile phone 120 can be projected onto the display 1101 of the notebook computer, and as shown in fig. 1 (b), the mobile phone window is projected onto the main interface of the mobile phone 120 only on the display of the notebook computer. As can be seen from fig. 1 (a), although the mobile phone 120 runs in the background as a video application, the window that is the video application after the screen is thrown cannot be directly displayed on the display screen of the notebook computer 110.

Fig. 2 shows an interface schematic diagram of a first electronic device and a second electronic device in the related art. As shown in fig. 2 (a), the main interface 1201 of the mobile phone 120 is displayed on the display 1101 of the notebook computer 110, and although the background operation of the mobile phone 120 is a video application, the playback interface of the video is not directly displayed on the notebook computer. Therefore, when the user needs to watch the video on the notebook computer 110, the video application needs to be searched and opened. As shown in fig. 2 (b), after the user clicks on the video application, the screen-drop interface 1201 of the mobile phone displayed on the display 1101 of the notebook computer 110 is switched to 1202 the display interface.

In summary, when the first electronic device establishes a connection to the second electronic device, the interface operation steps are relatively more, and when the first electronic device throws a screen to the second electronic device, only the main interface of the first electronic device is displayed on the second electronic device, so that the user needs to open the applications of the first electronic device on the interface of the second electronic device one by one.

In view of this, the present application provides a method for projecting a screen of an electronic device, where the method is applied to a first electronic device, where the first electronic device has a touch screen, and a second electronic device is placed on the touch screen of the first electronic device, and the first electronic device acquires a first parameter, where the first parameter includes at least one of the following: the dielectric constant variation of the touch screen of the first electronic device, the dielectric constant variation area of the touch screen of the first electronic device, or the weight of the second electronic device; and when the first parameter meets the preset condition, displaying an application program running on the second electronic device on the first electronic device. According to the method, the second electronic equipment can rapidly throw the screen to the first electronic equipment, and user experience is further improved.

Before introducing the method for projecting the screen of the electronic equipment, the electronic equipment provided by the application is specifically described. The embodiment of the application provides an electronic device, which is used for executing the method for projecting the screen of the electronic device, and the electronic device can refer to the electronic device with a larger display screen. For example, the electronic device in the embodiments of the present application may be a smart television, a projection device that can project on a wall, a computer, various portable notebooks, various tablet computers, and other electronic devices with display screens, and the like. Optionally, the electronic device may also be a personal digital assistant (personal digital assistant, PDA) with a larger display screen, a handheld device with a larger display screen, a computing device, a vehicle-mounted device, a wearable device, an electronic device in a 5G network or an electronic device in an evolved public land mobile network (public land mobile network, PLMN), etc., which the embodiments of the present application are not limited to.

In another possible application scenario, a user wants to rapidly screen a plurality of application programs running on a mobile phone onto a large-screen device, and the method for screen projection of the electronic device provided by the application can be used.

The first electronic device provided by the embodiment of the application may be an electronic device with a larger display screen, for example, a large-screen device, a tablet computer, a PC, a car machine, a smart screen, a folding screen device, and the like, and the electronic device with the larger display screen includes a touch screen.

The method for projecting the screen of the electronic device provided by the application is specifically described by taking the first electronic device as a folding screen device and the second electronic device as a mobile phone, wherein the folding screen device comprises: the mobile phone comprises a first screen area, a folding area and a second screen area, wherein the first screen area and the second screen area are touch screen areas, and the mobile phone can be placed in the first screen area or the second screen area.

Fig. 5 is a schematic diagram illustrating an example of a display interface of an electronic device according to an embodiment of the present application, where, as shown in fig. 5 (a), a mobile phone is placed in a first area on a second screen area of a folding screen device. And assume that application a, application B, and application C are running on the handset. When the mobile phone is placed on the second screen area of the folding screen device, the first electronic device obtains at least one of the following parameters: the change amount of the dielectric constant of the first area of the touch screen of the first electronic device, the area of the first area or the weight range of the second electronic device; when the variation of the dielectric constant of the first area of the touch screen of the first electronic device meets a preset first condition, the area of the first area meets a preset second condition, or the weight range of the second electronic device meets a preset third condition, the application a, the application B and the application C running on the second electronic device can be automatically screen-thrown onto the first electronic device, that is, as shown by an interface in the (B) diagram in fig. 5, the second screen area of the first electronic device can display the application a, the application B and the application C running on the second electronic device. The user may operate an application running on the second electronic device within the second screen region of the first electronic device.

The following describes how the first electronic device obtains the first parameter, and how the first electronic device determines whether the first parameter meets the preset condition.

Optionally, when the first parameter is at least one of the following: when the change amount of the dielectric constant of the first area of the touch screen of the first electronic device, the area of the first area or the weight range of the second electronic device, the first electronic device determines whether the change amount of the dielectric constant of the first area of the touch screen meets a preset first condition, whether the area of the first area meets a preset second condition and whether the weight of the second electronic device meets a preset third condition.

Firstly, when the second electronic device is placed on the second screen area of the first electronic device (folding screen device), the touch screen in the second screen area can sense current transmission change, the touch IC on the touch screen can detect signals of dielectric constants in the second screen area, and when the variation of the dielectric constants of the first area of the touch screen detected by the first electronic device meets a preset first condition, the object placed in the second screen area at the moment is the electronic device.

The preset first condition may be, for example, 1.5ε -2.2ε. Of course, the preset first condition may also be other value ranges, which is not limited in the embodiment of the present application.

The principle of the dielectric constant change when the second electronic device is placed on the touch screen of the first electronic device will be described below.

Fig. 6 shows a schematic diagram of a change in dielectric constant of a capacitive touch panel, as shown in fig. 6, when a user touches a capacitive screen, a coupling capacitor is formed between a finger of the user and a working surface due to an electric field of the human body, and because a high-frequency signal is connected to the working surface, the finger absorbs a small current, the current flows from electrodes at four corners of the screen respectively, and theoretically, the current flowing through the four electrodes is proportional to the distance from the finger to four corners, and a specific position of the user touching the capacitive screen can be obtained by precisely calculating the ratio of the four currents.

Similarly, the dielectric constant of any article is just non-insulator as long as the dielectric constant is greater than zero, and when any non-insulator is placed on the touch screen, the electric field of the capacitive touch screen can change, i.e. when any non-insulator is placed on the touch screen, the dielectric constant on the touch screen can change. When the mobile phone, the earphone or the plastic shell and other articles are placed on the screen, the capacitive screen can sense the current transmission change, so that the change of the dielectric constant on the touch screen is caused, and the object placed on the touch screen can be judged by utilizing the change of the dielectric constant on the touch screen.

Therefore, in the embodiment of the application, when the mobile phone is directly placed on the second screen area, the change amount of the dielectric constant of the first area of the touch screen of the first electronic device can be obtained through the touch IC, and according to the change amount of the dielectric constant of the first area of the touch screen of the first electronic device, the object placed on the second screen area is determined to be the electronic device.

For example, since the mobile phone contacts with the touch screen, the mobile phone is a mobile phone housing, and the mobile phone housing is usually made of glass, metal, plastic, or the like. When the touch IC obtains that the change amount of the dielectric constant of the first area of the touch screen of the first electronic device is the dielectric constant of the material such as glass, metal or plastic, whether the object placed in the second screen area is the electronic device can be judged according to the change amount of the dielectric constant.

Based on the principle of the change of the dielectric constant, in the embodiment of the present application, the size of the second electronic device may be determined by using the area of the first area of the touch screen of the first electronic device, and then whether the object is an electronic device may be determined according to the size.

The change area of the dielectric constant of the touch screen of the first electronic device is the size of the second electronic device placed on the first electronic device. And then further judging whether the object is an electronic device according to the size of the object. And when the change area of the dielectric constant of the touch screen of the first electronic device meets a preset second condition, indicating that the object is the electronic device.

The preset second condition may be, for example, 82.28cm ² -300cm ² . Of course, the preset second condition may also be other value ranges, which is not limited in the embodiment of the present application.

In the embodiment of the application, the first electronic device may further determine whether the object is an electronic device by measuring the weight of the second electronic device placed in the second screen area. I.e. when the weight of the object meets a preset third condition, it is indicated that the object is an electronic device.

Specifically, the touch screen of the first electronic device includes a gravity sensor, the gravity sensor can detect the weight of the object, and the first electronic device judges whether the object is the electronic device according to the weight detected by the gravity sensor.

The preset third condition may be, for example, 175g-2000g. Of course, the preset third condition may also be other value ranges, which are not limited in the embodiment of the present application.

In summary, when the amount of change of the dielectric constant of the first area of the touch screen of the first electronic device satisfies the preset first condition, the area of the first area satisfies the preset second condition, and the weight of the second electronic device satisfies at least one of the preset third condition, the first electronic device may switch from the interface in the diagram (a) shown in fig. 5 to the interface in the diagram (b) shown in fig. 5. At least one application running on the second electronic device, such as application a, application B, and application C, is displayed within the second screen area of the first electronic device.

In some embodiments, in order to improve the accuracy of screen projection and protect the privacy of the user, when the variation of the dielectric constant of the first area of the touch screen of the first electronic device meets at least one of the preset first condition, the area of the first area meets the preset second condition, and the weight of the second electronic device meets the preset third condition, the first electronic device sends an authorization request to the second electronic device, and when the second electronic device agrees to the authorization, at least one application running on the second electronic device can be displayed on the first electronic device.

Fig. 7 is an exemplary schematic diagram of an interface display of a first electronic device provided in the embodiment of the present application, where when a second electronic device is placed in a first area of a second screen area of the first electronic device and it is assumed that an application a, an application B, and an application C are running on the second electronic device, and when a first parameter acquired by the first electronic device meets a preset condition, as shown in fig. 7 (B), a multi-screen authorization popup window is displayed on the second electronic device, and after a prompt user "confirms the permission, the folding screen device displays an application interface in the mobile phone", and when the user clicks agrees, the interface of the first electronic device is switched from the interface shown in fig. 7 (a) to the interface shown in fig. 7 (B), that is, the application a, the application B, and the application C running on the second electronic device are displayed in the second screen area of the first electronic device.

In other embodiments, when the amount of change of the dielectric constant of the first area of the touch screen of the first electronic device meets at least one of a preset first condition, an area of the first area meets a preset second condition, and a weight of the second electronic device meets at least one of a preset third condition, in order to further improve accuracy of screen projection, the first electronic device may further obtain time for placing the second electronic device, and when the time for placing the second electronic device on the touch screen of the first electronic device is greater than or equal to a preset first threshold, at least one application running on the second electronic device is displayed on the first electronic device.

It should be understood that the preset first threshold may be set according to a specific situation, and embodiments of the present application are not limited.

Specifically, the gravity of the second electronic device may be obtained in real time by using a gravity sensor integrated on the touch screen of the first electronic device, and when the value of the gravity sensor in a certain time period is kept at a certain fixed value, it indicates that the second electronic device is placed on the first electronic device in the time period. The time period can be compared with a preset first threshold value, and whether the time period meets the preset first threshold value or not is judged.

Optionally, as a possible implementation manner, when the first electronic device determines that the time for which the second electronic device is placed is greater than or equal to a preset first threshold, the first electronic device actively sends an authorization request to the second electronic device, and when the second electronic device agrees to the authorization, an application running on the second electronic device may be displayed on the first electronic device.

In some embodiments, when a plurality of applications are run on the second electronic device and displayed on the second screen area of the first electronic device, the user may open any one of the applications on the second screen area so that it may be displayed in an enlarged manner. Fig. 8 is a schematic diagram illustrating an interface display of a first electronic device according to an embodiment of the present application, where, as shown in fig. 8 (a), when an application a, an application B, and an application C are displayed on the first electronic device, it is assumed that the application a is a WeChat application, the application B is a video application, and the application C is a photo application, when a user wants to view the enlarged view on the first electronic device, the user may click on the application B, and after clicking on the application B, a second screen area of the first electronic device is switched from the interface shown in fig. 8 (a) to the interface shown in fig. 8 (B). I.e. the video may be enlarged in the second screen area for viewing by the user.

It will be appreciated that, since the second electronic device is placed on the second screen area of the first electronic device, when the user views the enlarged window as a video in the second screen area, the window is obscured when the window is enlarged to a certain size, and that displaying the enlarged window on the second screen area affects the user experience to a certain extent since other applications are also displayed in the second screen area.

Therefore, in other embodiments of the present application, when a plurality of application programs running on the second electronic device are displayed in the second screen area of the first electronic device, the user may display any one of the opened application programs in the first screen area, so as to implement a multi-screen collaboration function, and finally, when the user views a certain application program, the user does not affect the display of other application programs, thereby improving user experience. As an example, fig. 9 shows a schematic diagram of an interface display of a first electronic device provided in an embodiment of the present application, where, as shown in fig. 9 (a), when an application a, an application B, and an application C are displayed on the first electronic device, and assuming that the application a is a WeChat application, the application B is a video application, and the application C is a photo application, when a user wants to view an enlarged WeChat application and does not want to affect the WeChat application, the user may drag the application B upward when clicking the application B, and when the application B drags to the first screen area, the interface of the first electronic device is switched from the interface shown in fig. 9 (a) to the interface shown in fig. 9 (B), that is, the interface of the application B is displayed on the first screen area of the first electronic device.

According to the method, whether the change amount of the dielectric constant on the touch screen of the first electronic device, the area of the first area or the weight of the second electronic device meets the preset condition is judged, and when the preset condition is met, the first electronic device and the second electronic device are quickly connected, so that the problem of complicated connection steps in the related art is solved, and after the first electronic device and the second electronic device are connected, at least one application program running on the second electronic device can be directly displayed on the first electronic device, the problem of long interaction path caused by the fact that the application program running on the second electronic device needs to be re-opened on the first electronic device in the related art is further solved, and therefore user experience is improved.

The application also provides another method for projecting the screen of the electronic equipment, when the second electronic equipment is placed on the touch screen of the first electronic equipment, the camera of the second electronic equipment is used for detecting the first electronic equipment, when the surface of the object at the opposite end is detected to be the electronic screen, a connection request is sent to the first electronic equipment, and after the first electronic equipment agrees to the connection request, the connection between the first electronic equipment and the second electronic equipment is established. The application running on the second electronic equipment can be automatically screen-thrown to the first electronic equipment, so that the problem of complicated connection steps in the related art is reduced, and after the first electronic equipment and the second electronic equipment are connected, at least one application running on the second electronic equipment can be directly displayed on the first electronic equipment, and the problem of long interaction path caused by the fact that the application running on the second electronic equipment needs to be re-opened on the first electronic equipment in the related art is further solved, so that user experience is improved.

Fig. 5 to fig. 9 describe a specific process of establishing a screen-throwing connection between the first electronic device and the second electronic device, and after the first electronic device and the second electronic device establish a connection, at least one application program on the second electronic device is thrown onto the first electronic device and then displayed in the following various forms.

As shown in fig. 12 (b), the user may also click on any of the functions in the secondary interface, and the tertiary interface under the window is displayed on the same screen. I.e. the user can click any one of the functions in the secondary interface in window 7 and the tertiary interface under window 7 is displayed on the same screen.

In some possible implementations, to facilitate comparison of different content of the same page, a plurality of windows of the same application may be displayed on the first electronic device. Fig. 13 is a schematic diagram of a display interface of another electronic device according to an embodiment of the present application, where, as shown in fig. 13 (a), when a plurality of application programs running on a second electronic device are displayed on a first electronic device in an overlapping manner, a user may display a plurality of identical windows on a screen by opening the window again. For example, when the second screen area of the first electronic device displays window 1, window 2, and window 3, the user may click on window 3 again, and the primary interfaces of two windows 3 are co-screen. As shown in fig. 13 (b), when a plurality of applications running on the second electronic device are displayed on the first electronic device in a tiled manner, the user can display a plurality of identical windows on the same screen by opening the window again. I.e. the user can click on window 7 again, co-screen the primary interface of two windows 7.

In some possible implementations, to facilitate comparison analysis of different windows, one-screen comparison may be performed on sub-pages of more than one window, or different sub-page comparisons of the same window may also be performed.

It should be understood that the steps shown in fig. 15 may be implemented by the first electronic device or a chip configured in the first electronic device. Specifically, the method 1500 includes: step S1510 to step S1520.

S1510, the first electronic device obtains a first parameter, where the first parameter includes at least one of: the change amount of the dielectric constant of the first area of the touch screen of the first electronic device, the area of the first area, or the weight of the second electronic device.

S1520, when the first parameter meets the preset condition, at least one application program running on the second electronic device is displayed on the first electronic device.

In one possible implementation, the preset condition may be: whether the variation of the dielectric constant of a first area of the touch screen of the first electronic device meets a preset first condition, whether the area of the first area meets a preset second condition, and whether the weight of the second electronic device meets at least one of a preset third condition.

It should be understood that the infrared camera detects and recognizes the content of the photographed picture through ISO sensitivity and focal length. When the second electronic device is placed on a non-electronic screen, the ISO sensitivity may be zero due to no light entering. Therefore, the infrared camera can be used for judging whether the contact surface is an electronic screen or not.

Optionally, in one possible implementation manner, when the second electronic device determines that the contact surface is an electronic screen, the second electronic device first sends a connection request to the first electronic device, after the first electronic device receives the connection request sent by the second electronic device, sends a connection establishment message to the second electronic device, and after the second electronic device based on the connection establishment message sent by the first electronic device, the second electronic device displays the running at least one application program on the first electronic device. In the implementation manner, through the authorization confirmation of the first electronic equipment and the second electronic equipment, the screen can be projected again under the condition that the user wants to project the screen, so that the privacy of the user and the accuracy of the screen projection are further protected.
