The kernel, shell, and file system together make up the basic operating system structure that allows users to manage files, run programs, and use the system. After power-on, the kernel is started, kernel space is activated, hardware is abstracted, hardware parameters are initialized, and virtual memory, a scheduler, signals and interprocess communication (IPC) are operated and maintained. And after the kernel is started, loading the Shell and the user application program. The application program is compiled into machine code after being started, and a process is formed.

Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.

In some embodiments, at least one application program runs in the application program layer, and the application programs can be Window (Window) programs carried by an operating system, system setting programs, clock programs, camera applications and the like; or may be an application developed by a third party developer such as a hi program, a karaoke program, a magic mirror program, or the like. In specific implementation, the application packages in the application layer are not limited to the above examples, and may actually include other application packages, which is not limited in this embodiment of the present application.

The 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. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is configured to manage all window processes, such as obtaining a display size, determining whether a status bar is available, locking a screen, intercepting a screen, controlling a display change (e.g., zooming out, dithering, distorting, etc.) and the like.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, the android operating system runs the C/C + + library included in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (such as fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and so on.

In some embodiments, the kernel layer further comprises a power driver module for power management.

In some embodiments, software programs and/or modules corresponding to the software architecture of fig. 4 are stored in the first memory or the second memory shown in fig. 2 or 3.

In some embodiments, taking the magic mirror application (photographing application) as an example, when the remote control receiving device receives a remote control input operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into an original input event (including information such as a value of the input operation, a timestamp of the input operation, etc.). The raw input events are stored at the kernel layer. The application program framework layer obtains an original input event from the kernel layer, identifies a control corresponding to the input event according to the current position of the focus and uses the input operation as a confirmation operation, the control corresponding to the confirmation operation is a control of a magic mirror application icon, the magic mirror application calls an interface of the application framework layer to start the magic mirror application, and then the kernel layer is called to start a camera driver, so that a static image or a video is captured through the camera.

In some embodiments, for a display device with a touch function, taking a split screen operation as an example, the display device receives an input operation (such as a split screen operation) that a user acts on a display screen, and the kernel layer may generate a corresponding input event according to the input operation and report the event to the application framework layer. The window mode (such as multi-window mode) corresponding to the input operation, the position and size of the window and the like are set by an activity manager of the application framework layer. And the window management of the application program framework layer draws a window according to the setting of the activity manager, then sends the drawn window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface in different display areas of the display screen.

In some embodiments, as shown in fig. 5, the application layer containing at least one application may display a corresponding icon control in the display, such as: the system comprises a live television application icon control, a video on demand application icon control, a media center application icon control, an application center icon control, a game application icon control and the like.

In some embodiments, the live television application may provide live television via different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

In some embodiments, a video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

In some embodiments, an application center may provide storage for various applications. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

The picture quality and the tone quality directly affect the sensory experience when the user uses the display device 200. With the rapid development of the display apparatus 200 and the media information, the functions of the display apparatus 200 are more and more diversified. Also, more and more excellent image pictures and sound effects can be provided on the display apparatus 200.

Nowadays, the speaker of the display device 200 is usually fixed at a specific position, which makes it difficult to improve the high tone quality and sound effect of the display device 200, thereby affecting the experience of the user in terms of hearing experience. Certainly, there are some sound boxes set behind the panel of the display device 200, and when the device is turned off, the sound boxes are hidden behind the panel of the display device 200; after the device is powered on, the speaker is ejected from the bottom of the display device 200.

However, although the sound quality of the sound box can be improved to a certain extent, the sound box can be only mechanically retracted or ejected under the influence of the on/off of the display device 200, and once the sound box is ejected or retracted abnormally, the sound box cannot be fed back to a user through the display device 200, so that the user cannot timely and comprehensively master the state of the sound box. In addition, although the sound box is hidden behind the panel of the display device 200, it occupies a certain space, so that the display device 200 may look thick and heavy as a whole.

Based on the above problems, the embodiment of the application provides a display device loudspeaker state detection method and a display device, and in the process of starting up a display device 200, whether a loudspeaker is normally folded in the last shutdown process can be known through an environment variable, and whether the loudspeaker is normally lifted in the current startup process can be known through a status register flag bit. When the high tone quality and the sound effect of the display device 200 are improved, the user can know the lifting condition of the loudspeaker of the display device more comprehensively, and the user is prompted to process in time. Fig. 6 is a schematic diagram illustrating a position of a speaker 201 on a display device 200 according to an embodiment of the present disclosure, where the speaker 201 in the embodiment of the present disclosure may be disposed on a surface of a bezel of the display device 200, and may be retracted into the display device 200 when not in use, and may extend out of the display device 200 when in use.

Fig. 7 is a flowchart of a display device horn state detection method according to an embodiment of the present application, and as shown in fig. 7, the display device horn state detection method includes the following steps:

step S101, during the boot process of the display device 200, the environment variables and the flag bits of the status register in the display device 200 are read.

The environment variable is used for storing the retracting state of the loudspeaker in the previous shutdown process of the display device 200; the flag bit of the status register is used to store the rising state of the speaker in the current power-on process of the display device 200.

The state register is used for storing some device states of the display device 200, in this application, the state of the speaker is usually written into a flag bit of the state register, and in the shutdown process, after the speaker is retracted, the display device 200 reads the final state of the speaker retraction and writes the state into the flag bit; in the process of starting up, after the loudspeaker is lifted up, the display device 200 will read the last state of the loudspeaker, and write the state into the flag bit, at this time, only the loudspeaker state in the process of starting up is stored in the flag bit, and the state in the last shutdown process is deleted. If the state register flag bit is only used for storing the loudspeaker state, the problem that a user cannot know that the loudspeaker is folded abnormally in the last shutdown process in the current startup process can be caused.

Therefore, in the embodiment of the present application, in order to avoid using the flag bit of the status register to store the speaker status during power on and the speaker status during power off, an environment variable is additionally set to store the speaker status during power off. The environment variable is not rewritten in the process of starting up the display device 200, and the previous state of the speaker is still stored, so that the state of the speaker in the last shutdown process and the state of the speaker in the current startup process are read simultaneously in the process of starting up the display device 200.

Step S102, according to the environment variable and the flag bit of the status register, determining whether the speaker is abnormally lifted in the power-on process of the display device 200 and/or abnormally retracted in the last power-off process.

Whether the loudspeaker is normally folded in the last shutdown process can be judged according to the content of the environment variable, and if the loudspeaker is abnormal, a user needs to be prompted when the loudspeaker is started; or judging whether the loudspeaker is normally lifted in the starting process of the display device 200 according to the flag bit of the status register, and if the loudspeaker is abnormal, prompting a user when the display device is started.

The detection results of the horn state in the startup and shutdown process include the following steps:

lift up exception and stow away exception, lift up exception and stow away normal, lift up normal and stow away normal, and lift up normal and stow away exception.

In step S103, in the case where there is a lifting abnormality and/or a retraction abnormality of the horn, a prompt pops up on the display device 200.

In the test result of the horn state, once the horn is abnormally lifted or the horn is abnormally retracted, a prompt needs to be sent to a user. Fig. 8 is a schematic view of one kind of prompt content shown in the embodiment of the present application, and fig. 9 is a schematic view of another kind of prompt content shown in the embodiment of the present application, and in some embodiments, the prompt may be divided into two types, one type is a prompt for abnormal loudspeaker lifting, as shown in fig. 8, and the other type is a prompt for abnormal loudspeaker retraction, as shown in fig. 9. In the case where there is a lifting abnormality of the horn, a notice of the horn lifting abnormality, for example, a case where the lifting abnormality and the stowage abnormality, the lifting abnormality and the stowage normality, and the like are popped up on the display device 200. In the case where there is only a stowage abnormality for the horn, a notice of the horn stowage abnormality, such as a case of lifting normal and stowage abnormality, pops up on the display device 200.

From the above, it can be seen that the display device horn state detection method in the technical scheme of the application can read the environment variable and the status register flag bit in the display device 200 in the startup process of the display device 200; judging whether the loudspeaker is abnormally lifted in the starting-up process of the display equipment 200 and/or whether the loudspeaker is abnormally folded in the last shutdown process according to the environment variable and the flag bit of the state register; finally, in the case of a lifting abnormality and/or a retraction abnormality of the horn, a prompt pops up on the display device 200. Since the environment variable in the present application stores the retracted state of the speaker in the previous shutdown process of the display device 200; therefore, in the process of starting up the computer at this time, whether the loudspeaker is folded abnormally or not can be known through the environment variable, and whether the loudspeaker is lifted abnormally or not can be known through the flag bit of the state register when starting up the computer at this time. When the high tone quality and the sound effect of the display device 200 are improved, the user can know the lifting condition of the loudspeaker of the display device 200 more comprehensively, and the user is prompted to process in time.

In addition, the loudspeaker box used at present is replaced by a loudspeaker, so that the space occupied by the loudspeaker can be reduced, and the display device 200 is lighter and thinner.

The content in the foregoing embodiment may be based on the detection of the speaker state by the controller 250 of the display device 200, and certainly, may also be based on the lifting control of the speaker of the display device 200 by the controller 250, and further, in some embodiments, before the step of reading the environment variable and the status register flag bit in the display device 200 in the power-on process of the display device 200, the method further includes:

step S201, in the shutdown process of the display device 200, detecting the retracted state of the speaker.

The display device 200 is provided with some middleware, after the display device 200 starts to perform a shutdown operation, the middleware actively sends a speaker retraction instruction to the controller 250 through the I2C bus, and the controller 250 controls the speaker retraction to detect the retraction state of the speaker after a time delay (for example, 5 s). The time delay is to give the sufficient retracting time of the loudspeaker, and the problem that the state of the loudspeaker is detected under the condition that the loudspeaker is not completely retracted, and further the detection result is inaccurate is avoided.

When the horn is retracted, there may be cases such as complete retraction, retraction timeout, and the like, and the state can be roughly classified into two types, normal retraction and abnormal retraction.

Step S202, writing the retraction state into the environment variable.

Since the flag bit of the status register has only one status at the same time, the detection can only be obtained from the flag bit in the boot process when the display device 200 is booted; the loudspeaker is in a lifting state, and the retracting state of the loudspeaker in the last shutdown process cannot be obtained. In order to solve the problem, in the embodiment of the present application, an environment variable is further used to store the retracting state of the loudspeaker in the last shutdown process, after the loudspeaker retracting operation is completed, the retracting state of the loudspeaker is obtained by reading the flag bit of the state register, and then the read state is written into a specific environment variable. Since the value of the environment variable can still be read after the display device 200 is rebooted, when the power-on detection is performed, whether the retracting state of the horn is abnormal in the last power-off process can be judged by reading the value of the environment variable, and whether the lifting state of the horn is abnormal in the current power-on process can also be judged by the flag bit of the state register.

Fig. 10 is a schematic diagram illustrating a shutdown process of the display device 200 according to an embodiment of the present application. As shown in fig. 10, in some embodiments, the above scheme of controlling the retraction of the horn by the controller 250 further includes, after writing the retraction state into the environment variable: the network of the display apparatus 200 is turned off. However, the shutdown process can be roughly divided into four links, namely, shutdown animation, speaker retraction control, network shutdown, and a shutdown process, and the speaker retraction control link needs to consume about 5 seconds of time, so that the time consumed by the system shutdown process of the whole display device 200 is too long, and the most intuitive display is that the main screen and the small screen of the display device 200 are not shutdown synchronously, thereby affecting the user experience.

Fig. 11 is a schematic diagram illustrating a shutdown process of another display device 200 according to an embodiment of the present application. As shown in fig. 11, in order to avoid the problem that the system of the display device 200 is shut down for too long, in some embodiments, the network of the display device 200 may be turned off before the stowed state of the speaker is detected. The middleware sends a horn retraction command to the controller 250 through the I2C bus, and the controller 250 controls the horn retraction. And detects the stowed state of the speaker when the controller 250 turns off the network operation of the display apparatus 200 to cause the display apparatus 200 to perform a real power-off procedure. In this embodiment, there may be a time of about 7 seconds between the beginning of the control of the horn retraction and the reading of the horn retraction state, sufficient for the horn to complete the retraction operation and update the flag bit of the horn state register. By the mode, the problem that the whole optical machine process is prolonged due to delayed operation can be avoided while the condition that the folded state of the loudspeaker is correctly stored.

In some embodiments, the raising control of the speaker of the display device 200 may be further performed based on the controller 250 of the display device 200, and further before the step of reading the environment variable and the status register flag bit in the display device 200 during the power-on process of the display device 200, the method further includes:

in step S301, during the power-on process of the display device 200, the rising state of the speaker is detected.

The display device 200 is provided with some middleware, which actively sends a horn lifting command to the controller 250 through the I2C bus after the display device 200 starts to perform a power-on operation, and the controller 250 controls the horn to lift, and detects the lifting state of the horn after a time delay (e.g. 5 s). The time delay is used for giving enough rising time to the loudspeaker, and the problem that the detection result is inaccurate due to the fact that the state of the loudspeaker is detected under the condition that the loudspeaker is not completely raised is avoided.

When the horn is lifted, there may be cases of complete lifting, overtime lifting, and the like, and the two states are roughly classified into a lifting normal state and a lifting abnormal state.

Step S302, write the raised status into the status register flag bit.

In the embodiment of the application, the rising state of the loudspeaker is obtained only by using the status register flag bit, the retracting state of the loudspeaker is obtained through the environmental variable, the status register flag bit and the environmental variable are not affected with each other, the state of the loudspeaker in the power on and power off process can be obtained after the display device 200 is powered on, more comprehensive judgment is given, and then an abnormal prompt is given.

In some embodiments, after the prompt pops up on the display device 200, it is also necessary to detect a feedback operation of the user on the prompt. As shown in fig. 8, the feedback operation given by the user for the prompt of the horn retraction abnormality may click the determination button. As shown in fig. 9, the feedback operation given by the user to the prompt for the horn lift abnormality may be clicking the ignore button or clicking the retry button. Then, in a case where the feedback operation is detected, the prompt is turned off.

Also, as shown in FIG. 9, the feedback operation includes ignore or retry, i.e., the user can click to determine or click to retry. In the case where it is detected that the feedback operation is a retry, the display apparatus 200 may control the horn to be raised again, and then continue to detect whether the raised state of the horn is normal. At this time, if the user has removed the obstacle, the horn-raised state detected again may become normal.

With reference to the content of the foregoing embodiments, the scheme provided by the embodiments of the present application can be further divided into a horn lifting control portion and a horn state detection portion. Fig. 12 is a schematic diagram illustrating a horn control process and a horn state detection process according to an embodiment of the present disclosure. As shown in fig. 12, the horn control process is divided into a power-on control process and a power-off control process, and in the power-on control process, processes of obtaining a horn lifting instruction, controlling the horn to lift, detecting a horn lifting state, and updating a flag bit of a state register are sequentially performed; and in the shutdown control process, sequentially acquiring a loudspeaker retraction instruction, controlling the loudspeaker retraction, detecting the loudspeaker retraction state and writing the retraction state into an environment variable.

In fig. 12, after the display device 200 is turned on, the state register flag and the environment variable need to be read respectively in the horn state detection process, so as to determine the rising state of the horn in the current turning-on process and the retracting state of the horn in the last turning-off process. And then, different prompts are respectively given according to the state of the loudspeaker.

In addition, the display apparatus 200 shown in fig. 6 may also control the speaker 201 to automatically raise or retract when the display apparatus 200 is normally used according to an instruction of a remote controller, for example, a remote controller key (such as a live broadcast key) is pressed for a long time, and if the current speaker is in a raised state, the speaker automatically retracts once; if the loudspeaker is in the retracting state, the loudspeaker is automatically lifted once. Therefore, the lifting of the horn can be manually controlled. For example, when a certain key of the remote controller is pressed for a long time to reach a specified duration, the horn automatically and frequently carries out lifting operation; and then a certain key of the remote controller is pressed for a long time to reach the specified time, and the loudspeaker stops lifting operation.

Alternatively, some options may be configured in the display device 200, such as [ the horn is kept in a descending state ] or [ the horn is kept in an ascending state ], and after the user selects the corresponding option, the horn is not automatically lifted when the device is turned on or turned off. This also gives the user more options.

The controller 250 is further configured to: in the case that there is a horn lift abnormality, popping up a horn lift abnormality prompt on the display device 200; and when the horn is only abnormally retracted, popping up a horn retraction abnormity prompt on the display device 200.
