Currently, functions of the display apparatus 200 are more and more diversified, and a user uses the display apparatus 200 for a longer time. When a user watches the display device 200, the user may be disturbed by external things and leave, and at this time, the display device 200 is in a normal display state where no one watches for a great probability; or the user is asleep unconsciously while watching the display device 200, the display device 200 may still be in a normal display state in which no one is watching.

It can be seen that after the display device 200 is used for a certain period of time, the display device 200 may be in an operating state even if the display device is not used by a person, and may not enter a sleep or standby state by itself, and although the display device may enter a screen saver state, the display device 200 may still be in a normal operating state, which not only greatly wastes power resources, but also accelerates the aging of the display device 200, and shortens the effective service life of the display device 200.

There are also methods to avoid the display device 200 being in an active state all the time, such as a timed power on/off function. However, after the function is turned on, once the timed time is up, the display device 200 will immediately become the standby state regardless of whether the user is using the display device 200, and if the user is using the display device 200, the standby-forcing manner inevitably causes the user to experience a poor experience. It can be seen that, although the function of timing on/off can prevent the display device 200 from being in the operating state for a long time, the user experience is greatly affected.

Based on this, the present embodiment provides a display device state control method, which can be applied to the display device 200 of the foregoing embodiment and executed by the controller 250 in the display device 200. As shown in fig. 5, the method may specifically include the following steps:

step S101, when the display device 200 is in the power-on state, determining whether the display device 200 receives an effective operation within a first preset time.

A timer is generally provided in the display apparatus 200, and starts counting time while the display apparatus 200 is turned on. The first preset time is a period of time after the timer starts to time.

The first preset time may be preset in the display apparatus 200 by a technician according to the general needs of the user, in which case the first preset time is not modifiable. Or, the display device 200 may also provide a plurality of options of the first preset time for the user, and when the user needs to set the first preset time, the user selects a certain first preset time according to his own requirements.

Referring to fig. 6, fig. 6 illustrates a schematic diagram of a time setting page on the display device 200 according to some embodiments. Several first preset time options may be displayed on the time setting page, such as 1 hour, 2 hours, 3 hours, etc. If the user selects the 1-hour option, it is necessary to determine whether the display apparatus 200 receives a valid operation within 1 hour; if the user selects the 2 hour option, it is necessary to determine whether the display device 200 receives a valid operation within 2 hours.

The user may temporarily leave the display device 200 due to some emergency or disturbance of some things while using the display device 200, and if the user does not return for a long time, the display device 200 may be left in an unattended operation state for a long time. In step S101, a first preset time may be used to determine whether the display device 200 is in an unattended state for a long time, and if the display device 200 receives a valid operation within the first preset time, it indicates that the user may return to continue using the display device 200, and at this time, the display device 200 is not in an unattended state for a long time; and if the display apparatus 200 does not receive a valid operation within the first preset time, it may indicate that the display apparatus 200 is in an unattended state for a long time.

When the display device 200 is in the power-on state or the running state, the content displayed on the display 250 may be video content, picture content, or a function page, a setting page, a screen saver page, or the like provided by the display device 200 itself. These content and pages may be displayed dynamically or statically.

In the embodiment of the present application, the effective operation may include, but is not limited to, an operation of the display device 200 by the user, a request sent by the external device received by the display device 200, and the like, and the effective operation may be an operation actively performed by the display device 200 according to the detected content or an operation passively performed by the display device 200 according to a control of the user, and the like.

The operation of the display device 200 by the user may be an operation of inputting a key instruction to the display device 200 by pressing a key of the control apparatus 100 such as a remote controller; or an operation of inputting the voice content to the display device 200 by the user, and the input of the voice content to the display device 200 by the user may be regarded as an input of a voice instruction to the display device 200; an operation of manually connecting an external device to the display device 200 by the user, or the like may be also possible.

In conjunction with the above, as shown in fig. 7, when determining whether the display device 200 receives a valid operation within the first preset time in step S101, step S201 may be executed first to determine whether the display device 200 receives a key instruction input by the user by pressing a key on the control apparatus 100 within the first preset time. In the case that the display apparatus 200 receives the key instruction within the first preset time, which indicates that the user needs to continue using the display apparatus 200 within the first preset time, in step S202, it may be determined that the display apparatus 200 has received the valid operation within the first preset time.

Taking the first preset time as 3 hours as an example, the timer starts timing when the user controls the display device 200 to play a certain video, and within 3 hours from the start of timing, if the user controls the display device 200 again through the remote controller, for example, the focus on the display page is moved to select the target content, etc., then it can be considered that the display device 200 has received a valid operation within 3 hours.

As shown in fig. 8, when determining whether the display apparatus 200 receives a valid operation within the first preset time in step S101, step S301 may be further performed first to determine whether the display apparatus 200 receives a voice instruction input by a user within the first preset time. In the case that the display apparatus 200 receives the voice instruction within the first preset time, which indicates that the user continues to use the display apparatus 200 within the first preset time, in step S302, it may be determined that the display apparatus 200 has received the valid operation within the first preset time.

Taking the first preset time as 3 hours as an example, the timer starts to count time from when the user controls the display device 200 to play a certain video, and within 3 hours of starting to count time, if the user inputs a voice instruction to the display device 200, such as "view today's weather", "watch movie" XXX ", etc., it can also be considered that the display device 200 receives valid operation within 3 hours.

As shown in fig. 9, when determining whether the display apparatus 200 receives a valid operation within the first preset time in step S101, step S401 of determining whether the display apparatus 200 is connected to an external apparatus within the first preset time may be first performed. In the case where the display apparatus 200 is connected to the external apparatus within the first preset time, which also indicates that the user continues to use the display apparatus 200 within the first preset time, it may also be determined that the display apparatus 200 has received a valid operation within the first preset time in step S402.

Taking the first preset time as 3 hours as an example, the timer starts to count time from when the user controls the display device 200 to play a certain video, and within 3 hours from the start of counting time, if the user inserts the usb disk into the usb port of the display device 200, it can be considered that the display device 200 has received valid operation within 3 hours.

In some cases, some external devices, such as bluetooth headsets, etc., may also actively detect the display device 200 and send a connection request or pairing request to the display device 200. If the display apparatus 200 receives a connection request or a pairing request transmitted from the external apparatuses within the first preset time, it may also be considered that the display apparatus 200 receives a valid operation within the first preset time.

Still taking the first preset time as 3 hours as an example, the timer starts timing when the user controls the display device 200 to play a certain video, and within 3 hours from the start of timing, if the bluetooth headset actively scans the display device 200 and sends a pairing request to the display device 200, it can be considered that the display device 200 receives valid operation within 3 hours. Also, the display apparatus 200 displays a pairing request page as shown in fig. 10 after receiving the pairing request.

In some cases, some applications or the like on the display apparatus 200 are automatically started or automatically run even if the display apparatus 200 is not operated by a person. In order to avoid the running of these applications or the starting of the applications affecting the timing of the timer, in the embodiment of the present application, an application white list may be configured for the display device 200, the applications that are easy to self-start are excluded from the application white list, and only the applications approved by the user or the technician are added to the application white list. Thus, only when an application in the application white list is launched or invoked will the display device 200 be deemed to have received valid operation, thereby eliminating interference from some useless or unimportant applications.

Furthermore, as shown in fig. 11, when determining whether the display device 200 receives a valid operation within the first preset time in step S101, step S501 may be executed first to determine whether the target application in the application white list of the display device 200 is called or started within the first preset time. In this case, if the target application is called, it may be considered that the display apparatus 200 has received a valid operation within the first preset time in step S502.

For example, after the user inputs a voice command to the display device 200, the user needs to call a voice service function on the display device 200 to implement specific control. Thus, voice assistant applications or programs or the like that implement voice service functionality may be added to the application white list. Thus, when the display apparatus 200 calls the voice assistant, it can be considered that the display apparatus 200 receives a valid operation.

As described above, when the user operates the display apparatus 200 within the first preset time, or the display apparatus 200 receives a request transmitted from an external apparatus within the first preset time, it may be considered that the display apparatus 200 receives a valid operation within the first preset time. On the contrary, if the user does not perform any operation on the display apparatus 200 and the display apparatus 200 does not receive any request from an external apparatus within the first preset time, it may be considered that the display apparatus 200 does not receive a valid operation within the first preset time.

In step S102, if the display device 200 receives an effective operation within the first preset time, the timer counts again, and further accumulates the first preset time again.

In this embodiment, if the display device 200 receives a valid operation within the first preset time, it indicates that the user is continuing to use the display device 200. In this case, in order to avoid that the automatic standby operation affects the normal use of the display apparatus 200 by the user, when the display apparatus 200 receives the valid operation, the standby operation is postponed and the timer is reset, the first preset time is accumulated again, and it is further necessary to continuously determine whether the display apparatus 200 receives the valid operation within the next first preset time.

Taking the first preset time as 3 hours as an example, if the user presses a key of the remote controller within 3 hours from the start of timing to input a key instruction to the display device 200, the display device 200 may respond to the key instruction to display a corresponding page or perform a corresponding operation. The display device 200 does not stand by at the end of the 3 hour counting, and the timer will restart counting at the time of receiving the key instruction, and accumulate the next 3 hours.

Alternatively, if the user inputs a voice command "view today's weather" to the display device 200 within 3 hours of starting the timer, the display device 200 displays the weather information of today on the display 260 in response to the voice command. Meanwhile, the timer also restarts timing at the moment of receiving the voice command, and accumulates the next 3 hours.

Alternatively, if the user inserts the usb disk into the U port of the display device 200 within 3 hours of starting the timing, the display device 200 will start to detect the usb disk, and the timer will start timing again at the time when the display device 200 connects to the usb disk, and accumulate the next 3 hours.

Or, within 3 hours from the start of the timing, the bluetooth headset actively scans the display device 200 and sends a pairing request to the display device 200, and the display device 200 displays a pairing request page, and meanwhile, the timer restarts the timing at the moment that the display device 200 receives the pairing request, and accumulates the next 3 hours.

Step S103, if the display apparatus 200 does not receive a valid operation within the first preset time, controlling the display apparatus 200 to be in a standby state when the first preset time is over.

In the embodiment of the present application, if the display device 200 does not receive the valid operation within the first preset time, it is considered that the display device 200 may be in an unviewed or unused state for a long time, and at this time, the display device 200 needs to be controlled to be in a standby state, so as to save power resources and prolong the service life of the display device 200.

In some embodiments, the display device 200 may also configure the power saving mode based on the above-mentioned control of the on state and the standby state, and provide a setting page with a power saving mode switch for a user, and the like. Referring to fig. 12, fig. 12 illustrates a schematic diagram of a mode setting page on the display device 200 according to some embodiments. The mode setting page can display options such as a power saving mode switch, the power saving mode switch is displayed in a control mode, when the control button moves rightwards, the power saving mode switch is turned on, and when the control button moves leftwards, the power saving mode switch is turned off.

When the power saving mode switch is turned off, the display apparatus 200 is always in a normal operation state regardless of whether the display apparatus 200 is watched by a user; when the power saving mode switch is turned on, the display device 200 may be controlled to be in the standby state only when the display device 200 is in the operation state where no one watches for a long time.

Further, in step S101, it may also be determined whether the power saving mode switch of the display apparatus 200 is turned on. If the power saving mode switch is turned on, it may be continuously determined whether the display apparatus 200 receives a valid operation within a first preset time. If the power saving mode switch is turned off, it is not necessary to determine whether the display apparatus 200 receives a valid operation within the first preset time.

In some embodiments, the display device 200 may further have a function of reserving to watch a program, that is, a user may set a reserved time to play a specific content at a fixed time according to his or her own needs or according to the time of playing the program. Then, as shown in fig. 13, when determining whether the display device 200 receives a valid operation within the first preset time in step S101, step S601 may be executed first to determine whether the display device 200 has the reserved content within the first preset time, and if the reserved content exists, then in step S602, it may be considered that the display device 200 has received the valid operation, and the display device 200 may automatically play the reserved content at the reserved time.

If the display apparatus 200 has the reserved content but the appointed playing time of the reserved content is not within the current first preset time, in order to ensure that the reserved content can be played normally, even if the display apparatus 200 does not receive the valid operation within the current first preset time, the display apparatus 200 is not controlled to stand by, but the display apparatus 200 is controlled to continue to wait until the appointed playing time, and the reserved content is played.

If the display apparatus 200 does not have the reserved contents and the display apparatus 200 does not receive any valid operation within the first preset time, the display apparatus 200 may be controlled to be in the standby state, thereby saving power resources.

In addition, when the display apparatus 200 plays the scheduled content according to the appointed play time, it is also necessary to restart the time counting, thereby newly accumulating the first preset time. And, it is also necessary to continuously determine whether the display apparatus 200 receives a valid operation within a new first preset time.

As described above, after the power saving mode switch of the display device 200 is turned on, the display device 200 can automatically switch to the standby state or maintain the on/off state according to the current operation condition. However, once the display apparatus 200 has the reserved content that the user has already reserved, the display apparatus 200 needs to play the reserved content at the appointed play time first even if the power saving mode switch is turned on. If the display device 200 still has the reserved content, the display device 200 still needs to play the reserved content according to the appointed playing time, and only when the last reserved content starts to be played, the display device continues to count again, so as to accumulate the first preset time again. And then continues to determine whether the display apparatus 200 has received a valid operation for the next first preset time. If the display apparatus 200 does not receive any valid operation within the next first preset time, the display apparatus 200 may be controlled to stand by.

It can be seen that, in the embodiment of the present application, the display device 200 with the reserved content is not affected by the power saving mode switch. If the display device 200 has the reserved content in different time periods in the power-on state, the display device 200 is not limited by the power saving mode even if the power saving mode switch is turned on in the current whole power-on state, but plays different reserved content in the whole course according to the appointed playing time.

To facilitate prompting the user that the display device 200 is about to enter a standby state when the display device 200 does not receive a valid operation, in some embodiments, the display device 200 may also display a standby countdown prompt page for the user. As shown in fig. 14, a standby countdown prompting page displays prompts such as "the display device is about to stand by, and if necessary, the user continues to press any button of the remote controller" and a standby countdown time display.

In this embodiment of the present application, a second preset time may be set to determine the display time of the standby countdown prompting page, that is, in a second preset time before the end of the first preset time, if the display device 200 still does not receive an effective operation, the display 260 is controlled to display the standby countdown prompting page in the second preset time.

Meanwhile, within the second preset time, if the display apparatus 200 receives a valid operation, the display apparatus 200 needs to respond to the operation, defer standby, and restart timing, thereby newly accumulating the first preset time.

For example, the first preset time is 3 hours, the second preset time is 1 minute, and if the display device 200 does not receive an effective operation within the first 2 hours and 59 minutes of the normal operation, the display device 200 displays a standby countdown prompting page at 2 hours and 59 minutes, and starts the countdown for 1 minute. Meanwhile, it is continuously determined whether the display apparatus 200 receives a valid operation within 1 minute of the countdown. If the display apparatus 200 receives a valid operation within the countdown time of 1 minute, it is necessary to postpone standby, respond to the operation, and start a countdown at the time when the valid operation is received. And if the display apparatus 200 has not received a valid operation within the time counted down by 1 minute, the display apparatus 200 is directly controlled to stand by at the end of the count down.

As can be seen from the foregoing, the display device state control method provided in the embodiment of the present application can be applied to the display device 200 of the foregoing embodiment, and is implemented by the controller 250 of the display device 200. The method may determine whether the display apparatus 200 has received a valid operation within a first preset time while the display apparatus 200 is in a power-on state. If the display apparatus 200 receives a valid operation within the first preset time, it may be determined that the display apparatus 200 needs to be continuously used, and at this time, the power-on state of the display apparatus 200 needs to be maintained. And if the display apparatus 200 does not receive a valid operation within the first preset time, it may be determined that the display apparatus 200 does not need to be continuously used, and it is necessary to control the display apparatus 200 to be in a standby state. The method in the embodiment of the application can automatically stand by when the display device 200 is not used for a long time, so that the power resource is saved, and the service life of the display device 200 is prolonged.
