Referring to FIG. 4, in some embodiments, the system is divided into four layers, from top to bottom, an application layer (referred to as an "application layer"), an application framework layer (Appl ication Framework layer) (referred to as a "framework layer"), a An Zhuoyun row (Android run) and a system library layer (referred to as a "system runtime layer"), and a kernel layer, respectively.

In some embodiments, at least one application program is running in the application program layer, and these application programs may be a Window (Window) program of an operating system, a system setting program, a clock program, or the like; or may be an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.

The framework layer provides an application programming interface (application programming interface, API) and programming framework for the application. The application framework layer includes a number of predefined functions. The application framework layer corresponds to a processing center that decides to let the applications in the application layer act. Through the API interface, the application program can access the resources in the system and acquire the services of the system in the execution.

As shown in fig. 4, the application framework layer in the embodiment of the present application includes a manager (manager), 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 to interact with all activities that are running in the system; a Location Manager (Location Manager) is used to provide system services or applications with access to system Location services; a Package Manager (Package Manager) for retrieving various information about an application Package currently installed on the device; a notification manager (Notification Manager) for controlling the display and clearing of notification messages; a Window Manager (Window Manager) is used to manage bracketing icons, windows, toolbars, wallpaper, and desktop components on the user interface.

In the related art, if the built-in video is stored in the standard Android data partition, since the partition is formatted (the built-in video is cleared) when the reset is performed in the upgrade, factory or user mode, a separate built-in video partition is separately created to store the built-in video file, and the built-in video file is formatted to avoid the reset. But the disadvantage of using independent built-in video independent partitions: firstly, the space occupied by the built-in video partition can only be deducted from the data partition available to the user, so that the available space of the user is reduced. Secondly, the built-in video partition can only be used by a market mode, and a user cannot select the market mode, so that the storage space occupied by the built-in video cannot be used by the user, and huge waste is caused for the user. Thirdly, the built-in video cannot break through the limitation of the size of the built-in video partition, and the compression quality and the demonstration effect of the built-in video of 4K or even 8K cannot be guaranteed.

In order to solve the above technical problems, embodiments of the present application provide a display device, and the structure and functions of each portion of the display device may refer to the above embodiments. In addition, on the basis of the display device shown in the above embodiment, the present embodiment further improves some functions of the display device.

In some embodiments, the preset file for market exhibition is stored in a standard Android data partition, where the preset file may be a built-in video, a built-in picture, a built-in audio, and the like. Taking the built-in video as an example, compared with storing the built-in video in a separate built-in video partition, the space occupied by the built-in video stored in the data partition is deducted from the data partition available to the user, but the space occupied by the built-in video stored in the standard Android data partition is available to the user. And the built-in video stored in the standard Android data partition can break through the limitation of the size of the built-in video partition. For example: the limitation on the independent built-in video partition is less than 1G, and the compression quality and the demonstration effect of built-in videos of 4K and even 8K cannot be ensured. If the built-in video is stored in a standard Android data partition, the user stores the data partition (the available space is generally required to be larger than 4G), but the memory space of the general data partition of the display device is 16GB or more, that is, the data partition is far larger than 4G, so that the built-in video file can break through the limit that the original built-in video partition is smaller than 1G, and a better demonstration effect is achieved.

It should be noted that, the Android System mainly has six partitions, which are Cache (Cache partition), MISC (MISC partition), recovery (Recovery partition), boot (start partition), system (System partition), and Data (Data partition), respectively. The cache data and instructions used by the program and the system are stored in the cache partition; the CPU will preferentially call the data here when the call and the execution command are; the MISC partition contains various system settings in on/off form, etc. These settings may include carrier or zone ID, USB configuration, and certain hardware settings, etc. This is an important partition and if it is damaged or lost, some of the functions of the device will not work properly. Also in the MISC partition is BCB (Bootloader Control Block, start control information Block), which is mainly the boot information for storing recovery patterns.

In the related art, when the preset file is stored in the standard Android data partition, if the user selects to restore the factory setting, the controller needs to execute the following steps, as shown in fig. 5, and fig. 5 is a flowchart of a method for restoring the factory setting according to a feasible embodiment.

Step S501: receiving an instruction of restoring factory settings input by a user;

Step S502: writing a command for formatting the data partition into a start control information block of the MISC partition;

specifically, main system writes into BCB Command ("boot-recovery-wipe_data");

step S503: restarting the display equipment, and entering a Recovery mode;

step S504: reading information in a starting control information block;

the method comprises the following steps: reading BCB Command of the MISC partition;

step S505: formatting data of the data partition;

step S506: formatting data of the cache partition;

step S507: erasing data of the MISC partition;

step S508: and restarting the display equipment and entering an android system.

When the preset file is stored in the standard Android data partition, the data of the data partition is formatted when the fifth step is executed, namely the preset file stored in the data partition is deleted. In the market mode and the factory mode, deleting the preset file can cause the file for market demonstration to disappear, and the purpose of market demonstration cannot be achieved.

In order to solve the above technical problems, embodiments of the present application provide a display device, and the structure and functions of each portion of the display device may refer to the above embodiments. In addition, on the basis of the display device shown in the above embodiment, the present embodiment further improves some functions of the display device.

In some embodiments, in order to better sell products, the market displays the display effects of products of different models, such as HDR, a highlight screen and the like, the display requirements of the display content of the built-in video and the models are consistent, the display effect is ensured, and therefore, the software requiring mass production needs to preset the built-in video. During mass production, the built-in video presetting step for market demonstration comprises the following steps: version compilation, version installation, restarting and entry into the android system.

The method comprises the steps of compiling versions, namely constructing a data partition mirror image file, wherein the data partition mirror image file is a data partition mirror image of a preset built-in video file;

packaging the data partition image file into an installation file, and deleting a command of starting a control information block in the MISC partition; and outputting a system installation file.

In some embodiments, after installation with the installation file, the recovery mode is not entered and entry into the android system may be restarted if the factory mode is not entered; if the factory mode is entered, the controller executes the step of restoring the factory setting, and specifically referring to fig. 6, fig. 6 is a flowchart of a method for restoring the factory setting according to a feasible embodiment.

Step S601: receiving a first instruction input by a user;

in some embodiments, the first instruction entered by the user includes an instruction to save the preset video and restore the factory settings.

Step S602: writing a delete data command into the start control information block;

in some embodiments, the MISC partition file holding the BCB control commands is exemplified as follows:

bootloader reads the boot control information block located in the MISC partition. The start control information block is a structure body storing a start command. According to different commands, the system can enter three different starting modes: mainSystem, recovery, bootloader. And executing different subcommands according to different recovery parameters.

In some embodiments, the Main System writes a delete data command ("boot-recovery-clear_data") to the boot control information block;

step S603: restarting the display device and entering a recovery mode;

step S604: reading the data deleting command in the starting control information block;

step S605: deleting all files except the preset file in the data partition;

in some embodiments, when the read start control information block contains a delete data command, deleting all files in the data partition except the preset file is performed. The preset file is often stored under a fixed path, and when the file is deleted, the operation of deleting the file may not be performed when the file is recognized as the file under the fixed path.

Step S606: formatting data of the cache partition;

in some embodiments, the cache partition stores log files and the like. The step of formatting the cache partition may be performed for a display device of conventional upgrade architecture; the step of formatting the cache partition may optionally not be performed for a display device employing an a/B seamless upgrade architecture.

Step S607: erasing data of the MISC partition;

in some embodiments, erasing the data of the MISC partition is mainly a command to erase the start control information block, avoiding the step of re-entering the resume mode after restarting the display device.

Step S608: restarting the display equipment and entering an android system.

In the embodiment of the application, a start control information block control command, namely a clear_data command, is newly added, if the clear_data command is detected after the recovery mode is started, the original operation of formatting the data partition is not executed any more, and the step of deleting all files and folders except the preset file in the data partition corresponding to the clear_data is executed, so that the same function of recovering the factory setting is realized, and meanwhile, the preset file is not deleted.

In the related art, a default system upgrade program packages a MISC partition pre-fabricated with a default start control information block control command into an upgrade file, while a data partition is generally an unformatted bare partition without a file system, so after the upgrade of the upgrade program is completed, the system enters a recovery mode after restarting, performs a wipe_data operation, formats the data partition, and enables the data partition to mount, read and write. That is, the display device in the mall mode may cause the preset file to be deleted during the system upgrade.

In order to solve the above technical problems, embodiments of the present application provide a display device, and the structure and functions of each portion of the display device may refer to the above embodiments. In addition, on the basis of the display device shown in the above embodiment, the present embodiment further improves some functions of the display device.

In some embodiments, when an upgrade file is manufactured, a start control information block command of a MISC partition in the original upgrade file is erased, and a partition image file (userdata. Img) of a corresponding data partition generated by system compiling is packed into the upgrade file. The partition image file of the data partition is a partition image file of the data partition of the preset file. The preset file may be the same preset file as before the upgrade, or may be a different preset file as before the upgrade.

When the display device detects that an upgrade file for upgrading the display device is available, the display device downloads the upgrade file from the server, and after checking the validity of the upgrade file, the display device selects to write the upgrade file into the system partition.

In some embodiments, the user may choose to default to allow the display device to automatically download and install when an upgrade file is detected. The idle time selected after the user runs out of the display device is downloaded and installed, and if the display device adopts an A/B seamless upgrade architecture, one system can be upgraded while the other system is running.

In some embodiments. The user does not select default to allow the display device to automatically download and install when the display device detects the upgrade file, and the upgrade file downloading reminding page is popped up when the display device detects the upgrade file; the upgrade file may be downloaded only after the user allows the download. When the upgrade file downloading is completed, the upgrade file installation reminding page is popped up. The upgrade file may be installed when the user allows installation.

Since the MISC partition of the control information block (wipe_data) command is not started in the upgrade file, the operation of formatting the data partition is not performed in the upgrade process, but a data partition image file (userdata. Img) of the preset file is written into the data partition, so that the preset file is stored in the data partition after the upgrade is completed. If the preset file of the partition image file arranged in the data partition is different from the preset file before upgrading, the preset file stored in the data partition before upgrading is replaced by a new preset file.
