In the related art, the latest android display device platform adopts an A/B seamless upgrading architecture; the A/B seamless upgrading architecture consists of the update _ engine and two independent systems of Slot A and Slot B. Assuming that the current system is running in the Slot A, when the system is upgraded, the Slot B system is updated based on the running Slot A system, and after the installation of the Slot B system upgrade package is completed, the system is automatically switched to the Slot B system only by once direct current or alternating current restart, so that the latest software can be enjoyed. After the mobile terminal is started, an OTA upgrading process is started, the OTA upgrading process interacts with a background server, an upgrading packet is detected, the upgrading packet is downloaded, the upgrading packet is verified, and the upgrading packet is installed. After the upgrade package is installed, the user is often forced to select a 'restart' button to enable the new version to take effect, so that the user is interrupted in watching television programs, and the user experience is influenced.

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 embodiments, the present embodiment further improves some functions of the display device. As shown in fig. 5, fig. 5 is a flowchart of the interaction between the user and the display device provided in the feasible embodiment.

The user performs step S501: inputting a starting-up instruction;

in some embodiments, as shown in fig. 6, fig. 6 is a schematic diagram of power state switching of a display device according to a possible embodiment. In fig. 6, the Power states of the display device include a normal operation state (on), a light sleep state (Active Standby), a Standby state (Suspend to RAM), a direct current Standby state (Power Off), and an alternating current Off state (AC Off). The system can be switched to a normal working state in a light sleep state, a standby state, a direct current standby state and an alternating current power-off state. Switching to a light sleep state may be done when there is a timed task in the standby state, for example: the user sets to perform the upgrade operation at two points in the morning, and the user enters a standby state after using the display device. When two points in the morning, the display device is switched from a standby state to a light sleep state, and upgrading operation is executed. The light sleep state may be switched to a standby state upon completion of the background task. For example, when the display apparatus performs the upgrade operation two points in the morning, the display apparatus is switched from the light sleep state to the standby state. The switch to the normal operation state can be based on the command of the application program in the light sleep state and the standby state.

The Active Standby also belongs to a sleep mode, and belongs to shallow sleep. In this mode, the CPU is not powered off, and can still receive and process certain events, and depending on the particular device, the CPU can return to the normal operating state faster than the standby state, but also consumes more power. For example: when the user enters sleep in a light sleep mode, the system can be awakened by clicking a keyboard subsequently; when the user enters sleep in a light sleep mode and sends a voice instruction, the display device can still respond to the user instruction and execute corresponding operation. Suspend to ram, commonly called standby and Sleep (Sleep), and enter this state, the main operations of the system are as follows: (1) storing data such as the current running state of the system in a memory, and supplying power to the RAM at the moment so as to ensure that the system is subsequently and quickly restored to a working state; (2) freezing a user-state process and a kernel-state task (a process entering a kernel state or a kernel-own task); (3) turning off peripheral equipment such as a display screen and a mouse, and interrupting and awakening peripheral equipment not to be turned off such as a power key; (4) and stopping the CPU. A direct current standby state (Power Off) which is a state in which the system is turned Off or the Power is turned Off; the AC Off state (AC Off) is a state in which an AC power supply is not turned on or Off, and is generally a state in which an AC power supply is cut Off or a power plug is unplugged.

In some embodiments, the user-entered power-on command is intended to cause the display device to enter a normal operating state. As shown in fig. 6, when the display device is in a light sleep state or a standby state, the user can input a power-on command by pressing a power key of the control device; a user can input a starting-up instruction by pressing a power key on the display device; the user can also input a power-on instruction by clicking a power key on an application program which is installed on a mobile device (such as a mobile phone and a tablet computer) matched with the display device and can control the functions of the display device. When the display device is in a light sleep state, the user can input a power-on instruction by speaking the voice information of 'turning on the display device'. When the display equipment is in a direct current standby state, a user can input a starting instruction by pressing a power key of the control device; the user may enter a power-on command by pressing a power key on the display device. When the display device is in an alternating current power-off state (the power plug is pulled out), a user can input a power-on instruction by inserting the power plug.

In response to the power-on command input by the user, the controller executes step S502: the display device is started.

After the display apparatus is started, the controller performs step S503: detecting whether an upgrade package exists;

in some embodiments, the OTA upgrade is divided into a display device side and a server side, and the server side is used to configure the display device upgrade package. After the display equipment is started, the OTA upgrading process actively interacts with the server side, and whether an upgrading package suitable for upgrading the display equipment exists or not is detected.

In some embodiments, the step of detecting whether there is an upgrade package suitable for the upgrade of the display device includes:

acquiring the version number/version code of the current display equipment;

acquiring the version number/version code of the display equipment at the server side;

comparing the version number or version code of the current display equipment with the version number/version code of the display equipment acquired from a server side;

if the version number or the version code of the current display equipment is the same as the version number/the version code of the display equipment acquired from the server, an upgrade package suitable for upgrading the display equipment does not exist;

if the version number or version code of the current display device is different from the version number/version code of the display device obtained from the server side, an upgrade package suitable for upgrading the display device exists.

If there is no upgrade package suitable for the upgrade of the display device, no operation is performed.

If there is an upgrade package suitable for the upgrade of the display device, the controller performs step S504: and controlling the OTA upgrading process to hold the wake-up lock.

In some embodiments, wake lock is a lock for display device power management that will control the display device to enter a light sleep (Active Standby) state after holding; and after the upgrading process holds the awakening lock, OTA upgrading operation can be carried out after the display equipment enters a light sleep state.

After the control upgrading process holds the wake-up lock, the controller executes step S505: reading the state of the attribute flag bit of the temporary power-off memoryless system, and judging whether the attribute flag bit of the temporary power-off memoryless system is in any unset state;

in some embodiments, the temporary power down memoryless system attribute flag bit is used to determine an upgrade progress status of the display device. When the display equipment does not detect the upgrade package, the temporary power-off non-memory system attribute flag bit is not set in any state; when the upgrading of the display equipment is in a state of finding a new version, temporarily powering off and not memorizing the attribute marking bit of the system to be 'found _ new _ version'; when the upgrading of the display equipment is in a downloading state, temporarily powering off and memorizing the attribute marking bit of the system to be 'downloading'; when the upgrading of the display equipment is in a downloading completion state, temporarily powering off and memorizing the attribute marking bit of the system to be 'down'; when the upgrading of the display equipment is in a checking state, temporarily powering off and memorizing the attribute marking bit of the system to be 'verifying'; when the upgrading of the display equipment is in a verification completion state, the attribute marking bit of the temporary power-off memoryless system is 'verified'; when the upgrading of the display equipment is in an installation state, temporarily powering off and memorizing the attribute marking bit of the system as 'installing'; when the upgrade of the display apparatus is in the in-installation state, the temporary power-off memoryless attribute flag bit is "installed".

The temporary power-off memoryless system attribute flag bit (sys. vt. ota. state) can keep memorializing in a normal operating state (on), a light sleep state and a standby state. I.e., the upgrade progress of the display device is not lost in the normal operation state (on), the light sleep state, and the standby state. The temporary power-down memoryless system attribute flag bit (sys. vt. ota. state) does not keep memorializing in both the dc standby state and the ac power-down state. That is, the upgrade progress of the display device is lost in the dc standby state and the ac power-off state. When the display device is in a DC standby state and an AC power-off state, the temporary power-off non-memory system attribute flag bit does not set any state.

If the temporary power-off non-memory system attribute flag bit is not set to any state, the controller executes step S506: and setting the temporary power-off memoryless system attribute flag bit to find a new version state.

In some embodiments, the fact that the status of the temporary power-off memoryless attribute flag bit is not set may be that an upgrade package suitable for the display device is detected to exist for the first time after the display device is powered on, and therefore, the upgrade progress status needs to be recorded in the temporary power-off memoryless attribute flag bit, that is, the temporary power-off memoryless attribute flag bit is set to a new version discovery status, which is specifically represented by setting the sys.

In some embodiments, the fact that the status of the temporary power-off memoryless attribute flag bit is not set may be due to that, after the last time the display device is powered on and detects that the upgrade package of the display device exists, although the upgrade progress status may have been recorded in the temporary power-off memoryless attribute flag bit, the temporary power-off memoryless attribute flag bit is set to find the new version status. However, the user turns off the display device in a direct current standby or alternating current power off mode, and the upgrade progress state recorded by the temporary power off non-memory system attribute flag bit is lost, that is, the temporary power off non-memory system attribute flag bit is changed into a state without any setting. Therefore, after the display device is turned on, the upgrade progress state needs to be recorded in the temporary power-off memoryless system attribute flag bit again, that is, the temporary power-off memoryless system attribute flag bit is set to a new version discovery state, which is specifically represented by setting the sys.

After setting the temporary power-off memoryless system attribute flag bit to the found new version state, the controller performs step S507: and reading the mark value of the attribute mark bit of the permanent power-off memory system, and judging whether the mark value of the attribute mark bit of the permanent power-off memory system is greater than a first preset value and not greater than a second preset value.

In some embodiments, the flag value (persistence. vt. ac. checktimes) of the permanent power-off memory system attribute flag bit is used to record the number of times of dc standby and ac power-off of the user, and it should be noted that the flag value of the permanent power-off memory system attribute flag bit records the sum of the number of times of dc standby and the number of times of ac power-off of the user. If the attribute flag value of the read permanent power-off memory system is 6, it indicates that the user turns off the display device in a direct-current standby or alternating-current power-off mode for 6 times continuously, and detects the system upgrade package for the 7 th time.

If the flag value of the attribute flag bit of the permanent power-off memory system is not greater than the first predetermined value, the controller executes step S508: and performing 1 addition operation on the mark value of the attribute mark bit of the permanent power-off memory system.

In some embodiments, the first preset value is set to 6, and if the flag value of the read persistent power-off memory system attribute flag bit is 3, an operation of adding 1 is performed on the flag value of the read persistent power-off memory system attribute flag bit, that is, 3+1 is 4. The user turns off the display device continuously for 3 times in a direct current standby or alternating current power-off mode, and the user can continue to use the display device when detecting that the system upgrade package exists in the 4 th time. If the user turns off the display device next time in a DC standby or AC power-off mode, the flag value of the flag bit for reading the attribute of the permanent power-off memory system next time is 4.

If the flag value of the attribute flag bit of the permanently powered off memory system is greater than the first preset value and not greater than the second preset value, the controller executes step S509: and controlling the display to display a first system upgrade reminding page.

In some embodiments, the first preset value is set to 6, the second preset value is 8, and if the flag value of the flag bit of the permanent power-off memory system attribute is read to be 7, it indicates that the user turns off the display device continuously for 7 times in a dc standby or ac power-off manner, and this time, the presence of the system upgrade package is detected for the 8 th time. Based on the using habit of the user, the user can be judged that the user often directly cuts off the power or presses a power key of the control device for direct current Standby after watching the television program, so that the steps of downloading, checking, installing and the like of the OTA upgrade package can not be carried out in the Active Standby light sleep state, therefore, when the mark value of the attribute mark bit of the permanent power-off memory system is larger than a first preset value and not larger than a second preset value, the display is controlled to display a first system upgrade reminding page, and the user is guided to execute the zero-interference OTA upgrade process.

In some embodiments, as shown in fig. 7, fig. 7 is a schematic diagram of a first system upgrade reminder page provided by a feasible embodiment. The first system upgrade alert page shown in fig. 7 includes a prompt 71 and a confirmation control 72, and further includes a selector 73 indicating that the confirmation control 72 is selected. The prompt message comprises' finding a new system software version, and advising you to upgrade when the television is in standby in order not to disturb your normal use; after the television is watched, please not unplug the power plug ".

It should be noted that the selector is used to indicate that any control has been selected, such as the focus object. In one aspect, the control may be selected or controlled by controlling movement of a display focus object in the display device according to an input from a user through the control means. Such as: the user can select and control the controls by controlling the movement of the focus object between the controls through the directional keys on the control device. On the other hand, the movement of each control displayed in the display device may be controlled according to the input of the user through the control device to cause the focus object to select or control the control. Such as: the user can control all the controls to move left and right through the direction keys on the control device, so that the focus object can be selected and the controls can be controlled when the position of the focus object is kept unchanged.

The form of identification of the selector is generally diversified. For example, the position of the focus object may be implemented or identified by enlarging the control, by setting a background color of the control, or by changing a border line, a size, a color, a transparency, an outline, and/or a font of a text or an image of the focus control.

After controlling the display to display the first system upgrade reminder page, the user performs step S510: the input instruction is used for closing the first system upgrading reminding page;

after receiving the instruction of closing the first system upgrade reminding page input by the user, the controller executes step S511 to control the display to cancel displaying the first system upgrade reminding page.

In some embodiments, in fig. 7, the currently indicated confirmation control 72 is selected, the user presses the confirmation key of the control device after reading the prompt message, and the display is controlled to cancel the display of the first system upgrade alert page in response to an instruction input by the user.

In some embodiments, after a first preset time (e.g., 2s) interval from the control display displaying the first system upgrade reminder page, the control display cancels the first display system upgrade reminder page without receiving any instruction input by the user.

After waiting for the user to use up the display device, the user performs step S512: inputting a command for turning off the power supply;

in some embodiments, the user enters a Power Off command by long pressing a Power key on the control device.

After receiving the instruction of turning off the power input by the user, the controller performs step S513: and controlling the display to display a second system upgrading reminding page.

In some embodiments, the first system upgrade alert page may be the same as the second system upgrade alert page, and the first system upgrade alert page may also be different from the second system upgrade alert page.

In some embodiments, as shown in fig. 8, fig. 8 is a schematic diagram of a second system upgrade reminder page provided by a feasible embodiment. The second system upgrade alert page shown in fig. 8 includes a prompt message 81 and a confirmation control 82, and further includes a selector 83 indicating that the confirmation control 82 is selected. The prompt message comprises that the system upgrading task is required to be executed when the television is in standby, and the television executes the standby operation at this time.

After controlling the display to display the second system upgrade reminder page, the user performs step S514: an input standby instruction;

in some embodiments, the user may input the standby instruction by pressing a power key of the control device for a short time.

In some embodiments, in fig. 8, the currently indicated confirmation control 82 is selected, and the user presses the confirmation key of the control device to input the standby instruction after reading the prompt.

After receiving the standby instruction input by the user, the controller executes step S515: controlling the display device to enter a light sleep state.

In some embodiments, after receiving a standby instruction input by a user, the controller may further control the display device to enter a standby state and then enter a light sleep state after a preset time.

In some embodiments, after the display is controlled to display the second system upgrade alert page, no instruction input by the user is received after a first preset time interval from the display to display the system upgrade alert page, and the display device is controlled to enter the light sleep state.

In some embodiments, after the display is controlled to display the second system upgrade alert page, after a first preset time interval from the display to display the system upgrade alert page, no instruction input by the user is received, and the display device is controlled to enter the standby state and then enter the light sleep state after the preset time interval.

In some embodiments, after the display is controlled to cancel the display of the first system upgrade reminder page, the user directly inputs a standby instruction by pressing a power key of the control device for a short time, so that the display device is controlled to directly enter the light sleep state, or the display device is controlled to enter the standby state and then enter the light sleep state after a preset time.

In some embodiments, the upgrade operation is performed immediately after the display device enters the light sleep state.

In some embodiments, after the display device enters the light sleep state, in order to prevent the display device from being turned off to enter the standby state or the light sleep state due to the user mistakenly pressing a power key of the control device or the local device, the upgrade operation is performed after the start-up instruction is not received after a second preset time interval from the time when the display device enters the light sleep state.

If the permanently powered-off memory system attribute flag bit is greater than the second predetermined value, the controller executes step S516: and executing upgrading operation.

In some embodiments, the first preset value is set to 6, the second preset value is 8, if the flag value of the flag bit of the permanent power-off memory system attribute is read to be 9, this indicates that the user turns off the display device by means of dc standby or ac power-off for 9 consecutive times, and this time, the presence of the system upgrade package is detected for 10 th time, and the user has been prompted to have the upgrade task currently for at least 2 times and does not turn off the power supply or ac power, but the user continues to turn off the display device by means of dc standby or ac power-off. Based on the using habit of the user, the steps of downloading, verifying, installing and the like of the OTA upgrade package can be judged to be impossible in the Active Standby light sleep state, so that when the attribute mark bit of the permanent power-off memory system is larger than the second preset value, the first system upgrade reminding page is not displayed, and the system is directly upgraded in the background in an A/B seamless upgrade mode.

In some embodiments, after the step of reading the flag value of the permanently powered off memory system attribute flag bit, the following steps may be performed:

judging whether the mark value of the attribute mark bit of the permanent power-off memory system is greater than a first preset value or not;

and if the mark value of the permanent power-off memory system attribute mark bit is not greater than the first preset value, performing an operation of adding 1 to the mark value of the permanent power-off memory system attribute mark bit.

If the mark value of the attribute mark bit of the permanent power-off memory system is larger than a first preset value, judging whether the display frequency of the first system upgrade reminding page is larger than a third preset value or not;

if the display frequency of the first system upgrade reminding page is not more than a third preset value, controlling the display to display the first system upgrade reminding page, and executing an operation of adding 1 to the display frequency of the first system upgrade reminding page;

and if the display times of the first system upgrade reminding page are larger than a third preset value, executing upgrade operation.

OTA upgrade architecture figure 9 is shown, and figure 9 is a schematic diagram of an OTA architecture provided by a possible embodiment. As shown in fig. 9, the server is used to make and manage the upgrade package, the display device sends a data request to the server after detecting that there is an upgrade package suitable for the local device, and the server and the display device perform data transmission and information interaction through a network. The whole process of OTA upgrading is as follows: (1) and (3) detection: the display equipment end is responsible for detecting that the server end has an upgrade package (2) suitable for the display equipment to download: the display equipment terminal downloads the upgrade package (3) from the server terminal for verification: and checking the validity of the downloaded upgrade package. (4) Installation: and erasing the upgrade package into the system partition.

In some embodiments, after the display device enters the light sleep state, the upgrade step is as shown in fig. 10, and fig. 10 is a flowchart of an upgrade method in the light sleep state provided by a feasible embodiment.

Step S101: monitoring the power state of the display equipment in real time;

in some embodiments, after the display device enters the light sleep state, the OTA upgrade process creates a new working thread, which is used to monitor the power state of the display device. Once the user inputs a power-on command, such as pressing a power key of the control device, the controller receives a screen on broadcast; when the user inputs a standby command, for example, presses the power key of the control device again, the controller receives a screen off broadcast.

Step S102: reading the state information of the attribute mark bit of the temporary power-off memoryless system;

the state information of the attribute flag bit of the system is not memorized in the current temporary power-off mode, namely the state of finding a new version;

step S103: downloading an upgrade package from a server side;

after the downloading is completed, step S104 is executed: verifying the validity of the upgrade package;

if the upgrade package is valid, executing step S105;

after the verification is completed, step S105 is executed: installing the upgrade package;

after the installation is completed, step S106 is executed: silent restart.

After the silent restart is successful, step S107 is executed: acquiring a current version number;

step S108 is executed: and if the current version number is a new version number, setting the mark value of the attribute mark bit of the permanent power-off memory system to be 0, and controlling the display equipment to enter a light sleep state.

In some embodiments, after the upgrade package is successfully installed, executing a quiesce Reboot logic of android native, completing switching of the new version, when the new version is successfully started, setting a flag value of a flag bit of the attribute of the permanent power-off memory system to 0, and controlling the display device to enter a light sleep state or a standby state, waiting for the user to use the display device again.

The above steps are performed in the case where the user does not use the display device during the upgrade process, but once the user turns on the display device during the upgrade process, the upgrade process needs to be stopped immediately.

In some embodiments, in the upgrading process, if a display screen starting broadcast is received, the upgrading operation is immediately stopped, and the current upgrading progress state is recorded to the attribute mark bit of the temporary power-off non-memory system;

in some embodiments, the status information of the temporary power down memoryless system attribute flag bit includes found new version (found _ new _ version), downloaded (downloading), downloaded (downloaded), verified (verifying), verified (verified), installed (installing), and installed (installed).

When receiving a display screen closing broadcast, controlling the display equipment to enter a light sleep state;

in some embodiments, after the display device enters the light sleep state, the state information of the attribute flag bit of the temporary power-off non-memory system is read immediately, and the upgrading operation is continuously executed according to the state information.

In some embodiments, after the display device enters the light sleep state, a power-on instruction of a user is not received within a second preset time period, the state information of the attribute flag bit of the temporary power-off non-memory system is read, and the upgrade operation is continuously executed according to the state information.

In some embodiments, if the state information of the attribute flag bit of the temporary power-off memoryless system is read as a new version, the step of downloading the upgrade package from the server side is executed; and if the state information of the attribute mark bit of the temporary power-off memorability-free system is read to be downloaded, executing a step of breakpoint continuous transmission, namely continuously downloading the upgrade package from the server side. The breakpoint resume function is a function of the server, and since the file names are the same, downloading is started from the breakpoint. For example, when the last upgrade package is downloaded to 45% of the interruption, when the upgrade package is requested again from the server, the download will be continued from 45% without re-downloading from 0%. If the status information of the attribute flag bit of the temporary power-off non-memory system is read as the completion of downloading, executing a step of checking the upgrade package; if the state information of the attribute mark bit of the temporary power-off non-memory system is read as the verification, continuing to execute the step of verifying the upgrade package; if the state information of the attribute mark bit of the temporary power-off non-memory system is read as the verification completion, executing the step of installing the upgrade package; if the state information of the attribute mark bit of the temporary power-off memoryless system is read as being installed, executing the step of recovering installation at the breakpoint; and if the status information of the attribute mark bit of the temporary power-off non-memory system is read as the installation completion, executing the step of silent restart.

In some embodiments, after the display device enters the light sleep state, the upgrade step is as shown in fig. 11, and fig. 11 is a flowchart of an upgrade method in the light sleep state provided by a feasible embodiment.

Step S111: judging whether the upgrade patch is installed;

if the upgrade package is installed, go to step S112;

step S112: silent restart;

if the upgrade package is not installed, executing step S113;

step S113: judging whether the upgrade package is in a state of installation stop;

if the upgrade package is in a state of installation stop, executing step S114;

step S114: continuing breakpoint restoration installation;

if the upgrade package is not in the installation-stopped state, executing step S115;

step S115: judging whether the installation package is in a state of completing downloading and verification;

if the upgrade package is in a state of completion of downloading and verification, go to step S116;

step S116: starting to install the upgrade package;

if the upgrade package is not in a state of completion of the download and verification, performing step S117;

step S117: judging whether the installation package is in a downloading stop state or not;

if the upgrade package is in a state of download stop, go to step S118;

step S118: continuing breakpoint transmission;

if the upgrade package is not in a download stopped state, go to step S119;

step S119: and starting to download the upgrade package.

In some embodiments, during a system upgrade, particularly when an upgrade operation has been started but not completed in a state where the display device is in a shallow sleep, the display device is turned off if the user finishes using the display device. But the display equipment is turned off directly by pulling out the power plug of the display equipment; or the display device is turned off by pressing the power key of the control device for a long time after the use is finished, and at this time, the display device still needs to control the display to display the first system upgrade prompt page shown in fig. 8. If the user still wants to turn off the power of the display device regardless of the page information or the user directly turns off the display device by unplugging the power plug of the display device. Both of the above two ways of turning off the display device may result in the system upgrade progress being lost. After the display device is turned back on, a re-upgrade is required in a light sleep state. Specifically, the OTA process is started, the upgrading package is detected to exist, the attribute marking position of the temporary power-off memoryless system is not set in any state, the attribute marking position of the temporary power-off memoryless system is set in a new version finding state, and in the process of upgrading in the light sleep state of the display equipment, if the upgrading package is found to be downloaded completely, the step of downloading the upgrading package can be directly skipped, the step of checking the upgrading package is directly carried out, and if the upgrading package is found to be checked completely, the step of installing the upgrading package can be directly entered. If the upgrade package is found to be installed, the step of silent restart can be directly entered.
