The display device 200 may have various functions such as browsing web pages, playing media assets, entertainment games, projecting screens, etc., thereby providing a wide variety of services to users. The user may control the display device 200 to launch a related application program to thereby launch a corresponding function.

In some embodiments, after the user controls the display device 200 to turn on, the display device 200 may start a system program, and the display device system may be an Android system. The display device system may run various applications to provide corresponding functionality to the user.

After the display device is turned on, the controller 250 may control a user interface to be displayed in the display 260. The user interface may be a specific target image, for example, various media materials obtained from a network signal source, including video, pictures and the like. The user interface may also be some UI interface of the display device 200, such as a system recommendation page or the like.

In some embodiments, a "My applications" control may be included in the user interface. The user may trigger entry into the corresponding application panel by clicking on the My application control to enter a display instruction for the application panel page. It should be noted that, the user may also input the selection operation of the function control in other manners to trigger entering into the application panel. For example, control is entered into the application panel page using a voice control function, a search function, or the like.

The user can view an application program that the display device 200 has installed, i.e., functions supported by the display device 200, through the application panel. It should be noted that, the application installed in the display device 200 may be a system application or a third party application. Fig. 5 shows a schematic diagram of an application panel in some embodiments. As shown in fig. 5, the application panel includes three controls, namely a "player", "game", and "video chat".

Some of the functions of the display device 200 can be implemented without connecting to a network, and some of the functions can be implemented after connecting to a network. When the user instructs the display device 200 to play the locally stored media content, since the play data corresponding to the media content is also stored in the display device 200, the controller 250 may directly control the display device 200 to play the media content according to the play data. For example, the display device 200 may store therein media assets such as movies, television shows, and the like, including video data and audio data corresponding to the media assets. The controller 250 may control the display device 200 to play the corresponding video data and audio data so that the user views the local assets.

However, when the user wants the display device 200 to play various media assets in the network, since the display device 200 does not store the play data of the network media assets, the display device 200 cannot directly play the network media assets, and the user needs to acquire the play data of the network media assets after connecting the network, thereby playing the network media assets. The display device 200 may be connected to an electronic device that provides a network, such as a router, to connect to the network provided by these electronic devices.

The display device 200 and the router device may be connected by a wired manner, thereby connecting a network. A wired network interface may be provided in the display device 200, through which one end of a network cable may be connected, and the other end of the network cable may be connected to a router device, so as to implement wired connection between the display device 200 and the router device.

The display device 200 and the router device may also be connected by wireless means. The router device may provide WiFi to which the display device 200 may connect to the network.

The display device 200 may be provided with a communicator, which may enable the display device 200 to be connected with other electronic devices in a communication manner, so as to implement operations such as data interaction. A bluetooth module may be included in the communicator for controlling the display device 200 to turn on and off bluetooth functions. The communicator may also include a wireless network module for WiFi connection, an infrared receiving module for receiving infrared signals, etc. Based on the communicator, the display device 200 may be in various forms of communication connection with an electronic device, including Bluetooth communication connection, infrared connection, wiFi connection, and the like.

FIG. 6 illustrates a schematic diagram of a function panel page in some embodiments. As shown in fig. 6, the function panel page may include various functions supported by the display device 200, such as a bluetooth function, a WiFi function, an infrared function. Each function may correspond to a mode, and the display device 200 may turn on a certain mode to implement the function corresponding to the mode, or turn off a certain mode to disable the function corresponding to the mode. The user may control the display device 200 to turn on or off either function.

In some embodiments, the display device 200 may be provided with a communication mode in consideration of communication security of the display device 200. When the communication mode is off, the display device 200 does not receive a communication connection request transmitted by the other electronic device. At this time, the display device 200 does not allow the electronic device to perform communication connection, and at this time, the display device 200 does not perform information interaction with any electronic device. When the communication mode is on, the display device 200 receives a communication connection request sent by the electronic device. At this time, the display device 200 may allow the electronic device and the display device 200 to be communicatively connected, thereby achieving information interaction.

In some embodiments, when the display apparatus 200 is in the communication mode, an authentication mode may be further set in consideration of security. When the authentication mode is off, the display device 200 does not authenticate the electronic device, and the electronic device can directly perform communication connection with the display device 200.

When the authentication mode is turned on, the display device 200 authenticates the electronic device. For example, when the display device 200 receives a communication connection request sent by the electronic device, the communication connection request is verified, and when the verification is passed, the communication connection request is allowed, so that a communication connection is made with the electronic device. Fig. 7 is a schematic diagram of setting an authentication mode in a display device in some embodiments. As shown in fig. 7, when the user selects the on communication mode, the on authentication mode or the off authentication mode may be further selected.

When the display device 200 is connected to a network, a user may control the display device 200 to implement a networking function, for example, may obtain network resources from a server for viewing.

In some embodiments, when a new version of the display device system exists, the server may push a system upgrade message to the display device 200 to inform the display device 200 to upgrade the system.

The controller 250 may control the display 260 to display a system upgrade prompt interface to query whether to upgrade the display device system. When the user instructs to upgrade the display device system, the controller 250 may download a system upgrade file from the server and perform an upgrade operation on the display device system according to the system upgrade file.

When upgrading the system, the display apparatus 200 may first enter a Recovery mode and perform a system upgrade operation in the Recovery mode. The recovery mode is an emergency state of the Android system, and can be used for recovery and repair operations when a problem occurs in the system. In the restore mode, the user may perform some advanced operations such as backing up the system, restoring factory settings, flashing, system upgrades, etc. The resume mode may also be entered when the display device 200 fails to properly run the system program. In the restore mode, the display device 200 may restore factory settings, thereby enabling system restoration.

The control program corresponding to the recovery mode is a separate program for upgrading or recovering the display device system. When the display device 200 is in the resume mode, the display device system is in an off state and does not operate. However, the networking function of the display device 200 is controlled by the display device system, i.e., the connection of the display device 200 to the network requires a state in which the display device system remains operational. Accordingly, the display apparatus 200 cannot connect to a network when the display apparatus is in the resume mode.

The display device 200 may not be normally updated when performing a system upgrade, for example, a downloaded system upgrade file is incomplete or a version error, etc. At this time, since the display device 200 is in the recovery mode, it is unable to connect to the network, and thus it is unable to detect the reason that the normal upgrade is unable to be performed at present through the network, and it is unable to re-download the system upgrade file by using the network, resulting in failure of the system upgrade.

When the display apparatus 200 operates the system, the system may not operate normally due to some program malfunctions. Alternatively, the display device 200 may have some failure, resulting in a failure to operate the system at power-on. At this time, the display apparatus 200 may enter a restoration mode, and the user may select to restore factory settings so that the system can operate normally. However, restoring factory settings may not repair the failure of the display device 200. Because the network cannot be connected, the display device 200 cannot detect the current failure cause by using the network, so that the display device 200 cannot work normally, and the use experience for the user is poor.

In some embodiments, the display device 200 may be connected to an external device and utilize the external device for system upgrade or system repair. The display device 200 may be provided with an external device interface 240, where the external device interface 240 is used to connect to an external device, so as to implement connection of the display device 200 to the external device, and the external device may be a set-top box, a data storage device, and the like. Based on the external device interface 240, data transmission between the display apparatus 200 and the external device is possible. The external device may transmit the external data stored by itself to the display device 200.

The display device 200 and the external device are provided with data interfaces with the same interface specifications and functions. Fig. 8 illustrates a schematic diagram of the connection of a display device and an external device in some embodiments. As shown in fig. 8, USB (universal serial bus) interfaces are provided on both the display device 200 and the external device. The user can insert two ends of the data line of the USB interface on the display device 200 and the external device respectively, and after the external device and the display device 200 are started, set the signal source of the display device 200 as the USB interface, so as to realize data transmission between the display device 200 and the external device. The external device may be a storage device such as a usb disk, or may be directly plugged into the external device interface 240, and the display device 200 may read data in the storage device.

The external equipment can store a system upgrade file and a system repair file. The controller 250 may obtain various files stored in the external device, perform a system upgrade operation on the display device system by using the system upgrade file, and repair the display device system by using the system repair file.

It should be noted that, although the display device 200 may perform a system upgrade or a system repair through an external device, the external device cannot help the display device 200 connect to a network. The mode of using external equipment is comparatively complicated. Meanwhile, the use of files provided by external equipment cannot guarantee certain success of the system upgrading and system repairing processes. When the system upgrade fails or the repair fails, the display apparatus 200 still cannot detect the current failure cause using the network.

In order to solve the above-mentioned problems, the display device 200 provided in the embodiment of the present application may have a function of being able to connect to a network in a recovery mode. After the display apparatus 200 enters the resume mode, the controller may control the display apparatus 200 to connect to the network such that the display apparatus 200 maintains the network connection state in the resume mode. When the system upgrade fails or the system repair fails, the display apparatus 200 may determine the failure cause using the network and re-perform the system upgrade or the system repair.

In some embodiments, the user may send a resume mode instruction to the display device 200 by operating a designated key of the remote control. And pre-binding the corresponding relation between the recovery mode instruction and the remote controller key in the actual application process. For example, a recovery mode key is provided on the remote controller, and when the user touches the key, the remote controller transmits a recovery mode command to the controller 250, and at this time, the controller 250 controls the display device 200 to enter the recovery mode.

In some embodiments, the user may send a resume mode instruction to the display device 200 by way of voice input using a sound collector of the display device 200, such as a microphone, to control the display device 200 to enter a resume mode. The display device 200 may be provided therein with an intelligent voice system that can recognize a user's voice to extract instruction contents inputted by the user.

In some embodiments, the resume mode instruction may also be sent to the display device 200 when the user controls the display device 200 using a smart device, such as using a cell phone. In the actual application process, a control may be set in the mobile phone operation interface, and whether to enter the recovery mode may be selected by the control, so that a recovery mode instruction is sent to the controller 250, where the controller 250 may control the display device 200 to enter the recovery mode.

A resume mode option may also be set in the system UI interface of the display apparatus 200, and when the user clicks the option, the display apparatus 200 may be controlled to enter or exit the resume mode.

In some embodiments, to prevent the user from false triggering the recovery mode, when the controller 250 receives the recovery mode instruction, the display 260 may be controlled to display recovery mode confirmation information, so that the user performs a secondary confirmation as to whether to control the display apparatus 200 to enter the recovery mode. Fig. 9 illustrates a schematic diagram of recovery pattern confirmation information in some embodiments.

FIG. 10 shows an interactive flow diagram of components of display device 200 in some embodiments, including the steps of:

s101, restarting the display device and controlling the display device to enter a recovery mode in response to an instruction for instructing the display device to enter the recovery mode;

s102, acquiring network driving data stored in a network file database;

s103, acquiring a target network driving file of the display equipment based on the network driving data;

s104, obtaining network connection information to be connected, wherein the network connection information to be connected comprises network information of a network to be connected and a network connection password;

s105, connecting the network to be connected based on the target network driving file and the network connection information to be connected.

In some embodiments, when an input instruction is received that instructs the display device to enter the resume mode, referred to herein as a resume mode instruction, the controller 250 may control the display device to enter the resume mode.

It should be noted that, during the operation of using the display device, the display device may run the system program to implement various functions. Since the resume mode and the display device system cannot be operated simultaneously, the controller 250 may restart the display device first. After the display device is started, the controller 250 controls the display device not to run the system program, and may control the display device to enter the resume mode.

In some embodiments, after the display device is powered on, the BootLoader may be used to control the display device to run the display device system or to control the display device to enter a resume mode. After receiving an instruction for instructing the display device to enter the recovery mode, the BootLoader can control the display device to enter the recovery mode after the next power-on.

In some embodiments, the display device may be provided with a resume mode instruction detection module for detecting whether the display device receives a resume mode instruction, i.e. whether an instruction instructing the display device to enter a resume mode is received.

The user may directly input a resume mode instruction to the display device, for example, by means of a control device or a system setting of the display device, to instruct the display device to enter a resume mode. Upon detecting a user instruction, the recovery mode instruction detection module may notify the controller 250. The controller 250 may instruct the BootLoader to enter the resume mode after the display device is next powered on. At the same time, the controller 250 may restart the display device. After the display device is restarted, the BootLoader controls the display device to enter a recovery mode.

In some embodiments, the resume mode instruction detection module may directly generate resume mode instructions when certain specific events are detected.

During the operation of the display device, the system may not operate normally due to some reasons, for example, more programs running in the display device cause the system to be blocked and not operate, or some components in the system fail to cause the system to crash.

When it is detected that the display device system cannot normally operate, the resume mode instruction detection module may generate a resume mode instruction, and the controller 250 may control the display device to enter the resume mode.

In some embodiments, the user may restart the display device when the display device system fails to function properly. A time threshold may be preset, and when the system is not operated for a time exceeding the time threshold, the controller 250 controls the display device to restart so as to normally operate the display device system.

It should be noted that, after the display device is restarted, the above problem may not be solved, so that the display device system still cannot operate normally.
