Fig. 2 is a block diagram of a software configuration of the terminal device 100 according to the embodiment of the present application.

The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system may be divided into four layers, an application layer, an application framework layer, an Android runtime (Android runtime) and system library, and a kernel layer, from top to bottom, respectively.

The application layer may include a series of application packages.

As shown in fig. 2, the application package may include applications such as camera, gallery, calendar, phone call, map, navigation, WLAN, bluetooth, music, video, short message, etc.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 2, the application framework layers may include a window manager, content provider, view system, phone manager, resource manager, notification manager, and the like.

The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, dialed and answered calls, browsing history and bookmarks, phone books, short messages, etc.

The view system includes visual controls such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying a picture.

The phone manager is used to provide the communication function of the terminal device 100. Such as management of call status (including on, off, etc.).

The resource manager provides various resources, such as localized strings, icons, pictures, layout files, video files, etc., to the application.

The notification manager allows the application to display notification information (e.g., message digest of short message, message content) in the status bar, can be used to convey notification-type messages, and can automatically disappear after a short dwell without user interaction. Such as a notification manager used to inform download completion, message alerts, etc. The notification manager may also be a notification that appears in the form of a chart or scroll bar text at the top status bar of the system, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, text information is prompted in the status bar, a prompt tone is given, the terminal device vibrates, an indicator light flickers, and the like.

The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system.

The core library comprises two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. And executing java files of the application program layer and the application program framework layer into a binary file by the virtual machine. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface managers (surface managers), Media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), and the like.

The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

The media library supports a variety of commonly used audio, video format playback and recording, and still image files, among others. The media library may support a variety of audio-video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

A 2D (an animation mode) graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The following exemplifies the workflow of the terminal device 100 software and hardware in conjunction with the user operation event.

When the touch screen 131 receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. The application framework layer obtains the original input event from the kernel layer, identifies the input event, and then triggers control of the terminal device. When the touch screen is damaged, the touch function of the local damaged area is invalid, so that a user cannot trigger a touch event through touch operation in the area. Therefore, in the embodiment of the application, the touch function can be checked, and then a suitable area is determined to display the page content of the terminal device, so that the user can perform touch operation in the area and can trigger a touch event.

The terminal 100 in the embodiment of the present application may be an electronic device including, but not limited to, a smart phone, a tablet computer, a wearable electronic device (e.g., a smart watch), a notebook computer, and a television.

In order to facilitate understanding of the control method of the terminal device provided in the embodiment of the present application, the following further describes the control method with reference to the accompanying drawings. It should be noted that the method provided by the embodiment of the present application is suitable for controlling the terminal device after the screen of the terminal device is damaged.

Fig. 3 is a flowchart illustrating a control method for a terminal device according to an embodiment of the present application. As shown in fig. 3, the method comprises the steps of:

step 301: after the screen is damaged, if first user operation on a first entity key is detected, the touch function of the screen is detected, and a closed area with a normal touch function is determined.

In some embodiments, after the screen of the terminal device is damaged, the user may enter a screen emergency mode through a first user operation of a first entity key. In order to protect the normal operation of the screen, before entering the screen emergency mode, it is necessary to determine whether an emergency mode identifier exists, and the specific steps are as shown in fig. 4:

in step 401, a first user operation on a first entity key is detected, and a screen emergency mode is triggered. Then, in step 402, it is determined whether an emergency mode identifier exists, if no emergency mode identifier exists, in step 403, the emergency mode identifier is written, finally, in step 404, a screen emergency mode is entered, and if an emergency mode identifier exists, step 404 is directly executed.

In the embodiment of the present application, the first physical key may be set as one or more key combinations as needed.

In another embodiment, determining whether the terminal enters the screen emergency mode or the screen normal mode after being powered on also needs to determine whether the emergency mode identifier exists. The method can be specifically implemented as the steps shown in fig. 5:

in step 501, after detecting a first user operation on a first entity key, recording an emergency mode identifier; in step 502, a power-on indication is received. Then, in step 503, checking whether the emergency mode flag exists, if the emergency mode flag is detected, then in step 504, entering the screen emergency mode, and executing the following operations, and if the emergency mode flag is not detected, then in step 505, entering the screen normal mode.

Therefore, the screen emergency mode is entered after the terminal screen is damaged through the first user operation of the first entity key.

In some embodiments, after entering the emergency mode, the touch function of the screen is detected, but it is unclear how to detect the touch function of the screen for the new user, so an operation demonstration of detecting the touch function of the screen is displayed in the embodiment of the present application. Fig. 6 shows how to detect the touch function in the form of animation to the user after entering the emergency mode. In order to facilitate the user operation, in the embodiment of the present application, an operation mode of an animation showing a cancel operation demonstration is also presented to the user. As shown in fig. 7, it is prompted in the screen whether to exit the screen power check operation by "clicking the volume entity key three times" during the playing of the animation, so that the user can exit the screen power check demonstration at any time.

In some embodiments, in order to determine the largest touchable area of the damaged screen, the touch function of the screen needs to be detected, and a closed area with a normal touch function is determined, which may be specifically implemented as the steps shown in fig. 8:

in step 801, a plurality of lines drawn in a screen by a user are acquired.

Wherein, the closed area is determined to show the page content conveniently and accurately. The screen damage type can be determined before acquiring a plurality of lines drawn in the screen by the user. One possible implementation is that a plurality of different screen damage types are displayed in the screen for the user to select, and since the touch function may be abnormal, the user is prompted to select the screen damage type by physical keys. May be implemented as the steps shown in fig. 9:

upon entering the screen contingency mode, the user is prompted to select a screen damage type, and several typical screen damage types are provided in step 901.

In step 902, the user is prompted to select a type of screen damage.

In step 903, a user operation for a third entity key operation is detected.

In step 904, if a user operation for a third physical key operation is detected, the selected screen damage type data is recorded and marked.

In step 905, if the user operation for the third physical key operation is not detected, the screen damage type data is not recorded.

As shown in fig. 10, the left diagram in fig. 10 shows several possible screen damage types for the user to select, and the user can select the screen damage type by the third physical key. For example, the user can move the focus by the physical keys for increasing and decreasing the volume, and on which option the focus is located, surround the option with a frame to facilitate the user to know the focus position, and then select the screen damage type of the corresponding focus position by the switch keys. The user can select one or more screen damage types according to actual conditions. As shown in the right panel of FIG. 10, the two screen impairment types selected by the user are "lower left corner impairment" and "middle impairment", respectively.

In some embodiments, if the provided option is appropriate, the user may also deselect the screen damage type, so in this embodiment of the application, at the stage when the user selects the screen damage type, the user may be prompted how to deselect the operation mode of the screen damage type. Such as prompting the user through which physical keys or combinations of physical keys to operate the cancel as shown in fig. 11 a. When the user does not need to select the screen damage type, the screen damage type selection can be quitted according to the prompt key, and the screen damage type is not recorded.

If the user selects the screen damage type, a recommended line can be displayed in the screen based on the selected screen damage type, and therefore the user can draw a plurality of lines on the screen based on the recommended line. For example, as shown in fig. 11b, if the screen damage type is a lower left corner damage, several horizontal lines and several vertical lines are displayed at the sitting position in the screen, so as to perform a detailed inspection on the touch function in the lower left corner region.

In implementation, the recommended line can be set according to the screen damage type and the actual situation, which is not limited in the embodiment of the present application. For example: the recommended lines of the full-screen drawing line can be set to be 11 horizontal lines and 5 vertical lines. If the user does not select the screen damage type, then the area of screen damage is not clear before the user draws the line. At this time, suggesting that the user draw a line in a full screen; if the user selects a screen corner, the user may be advised to draw a line at the selected screen corner, with other screen damage types being handled in a similar manner.

Step 802: and determining the position of the damaged touch point according to the touch points of the lines drawn by the user.

In the process of drawing the line, if the user draws the line at a substantially uniform speed, the obtained distances between the coordinates of the touch points are substantially equal, and at this time, if the distances between the touch points are larger and/or the touch points of the line have larger deviation, if the sudden change of the line direction can be understood as the deviation of the touch points, the line is indicated to have a line breaking point and a drifting point, so that the position of the damaged touch point can be determined. As shown in fig. 12, touch point disconnection or drift occurs at the position where the crack occurs, and the position of the damaged touch point can be detected by the above features.

Step 803: and determining a closed area based on the position of the damaged touch point.

In some embodiments, a maximum rectangular area may be found based on the location of the damaged touch point, where the damaged touch point location is not contained within the maximum rectangular area.

In some embodiments, if the user selects the screen damage type, the closed area with normal touch function can be determined according to the determined position of the damaged touch point and the recorded at least one screen damage type. For example: if the user selects the damage to the lower left corner when selecting the screen damage type, and meanwhile, more damaged touch points on the lower left corner are determined in the user screen function detection, the reliability of the damaged area of the screen on the lower left corner is high, and the determined closed area with normal touch screen function can avoid the area on the lower left corner of the screen.

The lines drawn by the user can be horizontal lines, vertical lines, oblique lines, diagonal lines, square lines or a combination of several lines, and are all suitable for the embodiment of the application. The process of determining the closed region will be further described below with reference to the steps shown in fig. 13, taking the example of drawing horizontal and vertical lines.

In step 1301, the user draws a line laterally.

In step 1302, the coordinates of the touch point with the damaged horizontal line are recorded.

In step 1303, it is determined whether the horizontal scribing is completed, if not, the process returns to step 1301, and if yes, the user performs the vertical scribing in step 1304.

If the user can press keys to select the line drawing completion, the judgment can be carried out according to whether the number of the drawn lines reaches the recommended number of the lines. If the number of the recommended lines is reached, marking is finished, otherwise, judging that marking is not finished.

In step 1305, the coordinates of the touch point with the damaged vertical line are recorded.

In step 1306, it is determined whether the vertical scribing is completed, if not, the process returns to step 1304, and if so, the closed region is determined in step 1307.

In step 1308, it is determined whether the enclosed area satisfies a predetermined condition. If the preset condition is not met, in step 1309, it is determined whether to trigger the user operation on the fourth entity key, if the user operation is triggered on the fourth entity key, the step 1301 is returned to, and if the user operation is not triggered on the fourth entity key, the position of the closed area is stored in step 1310. If the predetermined condition is satisfied, go to step 1310.

And continuously drawing the line on the screen by triggering the fourth entity key.

The preset condition can be judged by whether the closed area is generally matched with the display ratio of the horizontal screen or the vertical screen of the screen. And if the aspect ratio of the closed region is determined to be similar to the aspect ratio of the screen, determining that the preset condition is met, otherwise, determining that the preset condition is not met.

Therefore, the closed area with the normal touch function can be determined through detecting the touch function of the screen.

In some embodiments, after the closed region with the normal touch function is automatically determined, the closed region may be displayed, so that the closed region may be adjusted according to a user requirement, for example, the user may be prompted to adjust the displayed closed region by operating the second entity key.

One possible implementation manner is to use the displayed closed region as a region to be adjusted, when the area of the displayed closed region is too small or the aspect ratio is not reasonable, a user operates an entity key to adjust a line on a screen to a proper position, adjust a proper closed region, and store the closed region modified by the user as a finally determined closed region. Fig. 14 is a diagram showing the effect of the closed region after correction. Wherein, the displayed closed area has a sideline at the edge of the screen without adjustment. Embodiments of adjusting the enclosed area may include the steps shown in fig. 15:

in step 1501, the user is prompted to press a key to exit the manner of the correction area.

In step 1502, a user action on a second physical key is detected, and a bar on the screen is adjusted to an appropriate position and identified.

In step 1503, it is determined whether or not the closed region has been adjusted, and if the closed region has been adjusted, the key operation is confirmed in step 1504, and if the closed region has not been adjusted, the process proceeds to step 1502.

And if the corrected closed area is adjusted to be in a proper size, finishing the adjustment, otherwise, continuing the adjustment.

In step 1505, the corrected closed region position is stored.

Therefore, the user can enlarge or reduce the area range or adjust a more reasonable display aspect ratio through the physical key operation under the condition of not influencing the actual touch operation, and finally determine a more suitable closed area.

Step 302: and mapping the page content to be displayed in the finally determined closed area.

In some embodiments, the page content may be scaled to the size of the closed area for presentation, and the scaling may be performed according to the aspect ratio of the page in order to keep the page from being stretched.

In another embodiment, the page may not be zoomed, and a scroll bar is added when the page is displayed, so that the user can view the content of the page through the scroll bar.

Of course, when the closed area is small, the page content can be also scaled to a certain extent and a scroll bar is also added to help the user view the page content.

In some examples, after mapping the page content to the closed region presentation, the user may use the controls in the page in the closed region again, with the specific effect as shown in fig. 16. The screen area outside the closed area may be a black screen, may also be content that the user sets for display by himself, and may also be a default screen, such as a home screen, which is not limited in the embodiment of the present application.

In some embodiments, the emergency mode identifier is recorded if a first user action on a first physical key is detected. And if the closed area is not stored in advance, after the closed area is determined by touch function inspection, displaying page content by adopting the closed area and storing the closed area. After the next startup, if a startup instruction is received, after the emergency mode identification is checked, the pre-stored closed area display page content is directly read.

Of course, after the computer is turned on, if the emergency mode identifier is checked, the operation mode of canceling the emergency mode can be prompted. For example, a page such as that shown in FIG. 17 may be displayed prompting the manner of operation to exit the limp-home mode. If the user selects to quit the emergency mode, the emergency mode identifier can be deleted, the pre-stored closed area can be deleted, and then the normal mode is entered for displaying. The normal mode in the application refers to a mode for displaying page content based on a screen size according to a normal screen touch function. The emergency mode refers to displaying page content according to a predetermined closed area.

The timing for prompting to exit the emergency mode may be determined according to a requirement, for example, after a first user operates a first key, for example, when an enclosed area is displayed, for example, when a page is mapped to a determined enclosed area for display. In short, the user can exit the emergency mode at any time.

In the embodiment of the present application, each entity key may be the same or different, and may include one or more key combinations, as long as different operations can be distinguished, which are all applicable to the embodiment of the present application. For example, the volume up key may be used as a first physical key, the volume down key may be used as a second physical key, and the volume up key and the volume down key may be combined to be used as a third physical key.

Of course, the user can control the terminal device by using a voice instruction or by using machine vision before the closed region is not determined in the case of screen damage through not only the physical key operation. For example, the emergency mode is started by voice control, the screen damage type is selected by voice control, the emergency mode is exited by voice control, the operation demonstration is exited by voice control, the screen damage type is deselected, and the like.

Based on the foregoing description, in the embodiment of the application, by detecting the touch function of the screen, determining the closed region with the normal touch function, and mapping the content of the terminal screen into the closed region with the normal touch function for display, the problems that after the screen of the touch screen is damaged, the terminal equipment cannot be controlled, the life cycle of the terminal may be abnormally ended, and normal services cannot be timely developed are finally solved.
