It should be understood that the solution of the present application can be applied in the field of control of display screens, and in particular in the context of managing a plurality of display screens by a central control system. In such a scenario, the multiple display screens are typically located at different physical addresses, and the content they play is typically determined by an external system. The display screen plays according to the acquired video or data, or displays the corresponding picture according to the operation of the user of the display screen.

With the rapid development of the LED display technology, the application scene of the LED display screen is wider and wider. The attention to energy conservation and consumption reduction of the display screen is gradually increased, and many application scenes have the requirement of low power consumption through dormancy and awakening. In the related art, a display screen generally determines whether it can enter a sleep state according to a state in which it plays a video, and when there is no operation instruction or no video to be played for a certain period of time, the display screen enters the sleep state and is awakened by a play instruction when the video is to be played. However, in such schemes, the sleep and wake-up operation generally requires manual configuration of the display screen terminal, so as to allow the display screen to sleep or wake up according to the sleep and wake-up conditions set manually, and when the play content is greatly changed, manual adjustment is required frequently, so that the flexibility and adaptability of the scheme are low, and the maintenance cost is high.

Based on the above, the technical scheme of the embodiment of the application provides a display screen control scheme. The scheme can be applied to a scene that a central control system corresponds to a display screen in a plurality of display points, the display screen in the scheme can automatically enter a low-power consumption black screen for dormancy, and a program list arranged on the display screen can be automatically awakened, so that the scheme can be applied to an LED display screen system with long dormancy time, such as an advertisement screen, a conference screen, a home theater and the like. Referring to fig. 1, fig. 1 is an exemplary system architecture of a display control scheme applied to a display control system according to an embodiment of the present application. As shown in fig. 1, the system architecture mainly includes a central control management system 100, a broadcast control system 110, a video transmission system 120, a video receiving system 130, a transmission card 140 and a display screen 150. The central control management system 100 at site 1 communicates with various broadcast control systems 110 via a local area network or wide area network connection. The central control management system 100 is used to manage the display 150 of multiple display sites to play content and to schedule video programs to be played and to set up the play control system. The broadcast control system 110 communicates with the sender card 140 for transmitting video data to the sender card 140.

In addition, one of the play control systems 110 may manage one or more of the display screens 150. The broadcast control system 110 sends video data to the display screen 150 for playback via the sending card 140. The transmitting card 140 is used for transmitting the converted display instruction and data to the display screen 150.

Referring to fig. 2, fig. 2 is a schematic flowchart of an overall flow of display control in an embodiment of the present application. As shown in fig. 2, in step S10, the central control system sets sleep and wake-up trigger conditions of each display screen according to application environments of different display screens through a local area network or a wide area network. Subsequently, in step S20, the transmitting card monitors the data of the video played on the display screen, and transmits a sleep or wake-up instruction when the sleep and wake-up trigger conditions are met. In step S30, the display screen turns off the display module driving and the row tube chip of the display screen according to the sleep or wake-up instruction, and turns off the switching power chip voltage output, which is used to supply power to the display module and the row tube chip. Subsequently, in step S40, in response to the display screen receiving the sleep wakeup command, the display screen controls the switching power chip to start outputting voltage, so as to turn on the LED chip, the driving chip, the row tube chip, and the like of the display screen.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a display screen according to an embodiment of the present application. As shown in fig. 3, the display 150 includes a plurality of display cases 151. Each display housing contains a power supply 152, a switching power chip 153, a control card 154, a driver chip 155, and a row die 156. The control card 154, also called a receiving card or a driving card, is used for receiving data (including control command data and image data) transmitted by the transmitting card, processing and driving the display module, and monitoring the operation state of the whole display box. The LED display array, the driving chip circuit, the line chip circuit and the DC switch power chip circuit form a display module of the display screen, and the display module is used for displaying video images. Each display unit (box) is formed by splicing a plurality of display modules. The ADC switch power supply is a power supply of the whole display unit (box body) and supplies power to the control card and the display module.

The implementation details of the technical scheme of the embodiment of the application are described in detail below: referring to fig. 4, fig. 4 schematically illustrates a block diagram of a control system for a display screen, for example, a terminal or a server where the control system for a display screen may be located in an embodiment of the present application. Referring to fig. 4, the display control system at least includes a central control module 410, a plurality of transmitting cards 420 and a plurality of display screens 430, wherein each transmitting card corresponds to one display screen, and the following details are described below:

the central control module 410 sends control condition data corresponding to the display screen to each sending card.

The central control module contains control condition data of each display screen. The control condition data may be preconfigured data or data determined by the central control system according to the condition of the display screen. The control condition data is used to define conditions that trigger a state switch of the display screen. It will be appreciated that the display may be switched between a plurality of states and the central control module may set corresponding switching conditions for each state, for example, the states of the display may include a sleep state, an awake state, a high performance state, an emergency state, and the like. The control condition data may include trigger conditions or end conditions or both of one or more states. For example, a condition for triggering sleep and a condition for ending sleep may be included for the sleep state, a condition for triggering wake may be included for the wake state, and the like.

The transmitting card 420 monitors video playing data of the corresponding display screen.

The transmitting card monitors the video play data of the display screen. Video play data of a display screen refers to data related to a video currently being played by the display screen. Such as the content of the video being played, the picture, the audio, the duration, the brightness, the refresh rate, etc. It can be understood that the video played by the display screen may be provided to the display screen by the transmitting card, so that the video playing data of the display screen may be monitored by analyzing the video data to be transmitted to obtain the video playing data before transcoding the video data to the display screen, or collecting the content played by the display screen and analyzing the content to obtain the video playing data in the playing process of the display screen. In some embodiments, the sending card may also be replaced with a video processing module.

If the sending card 420 determines that the video playing data meets the control condition data, the sending card controls the corresponding display screen to be converted into a specified state according to a control instruction corresponding to the control condition data;

The display screen 430 executes the control instruction of the transmitting card to transition to the specified state.

If the video playing data meet the control condition data, the display screen is required to be switched to a specified state currently, and therefore the display screen can be controlled to be switched to the specified state according to a control instruction corresponding to the control condition data. It is understood that there is a correspondence between the control condition data and the specified state, that is, the control condition data is used to determine whether to switch to the specified state. The control condition data, the control instruction and the appointed state have a corresponding relation, the control condition data is used for detecting whether to switch to the appointed state, the control instruction is used for enabling the display screen to switch to the appointed state, and the appointed state can be one of running states of the display screen, including a dormant state, a wake-up state and the like.

Specifically, the display screen may enter a sleep state by controlling the display screen to display a sleep screen and powering down the display-related module. Specifically, please refer to fig. 5. Fig. 5 is a schematic flow chart of a sleep entering process in an embodiment of the application. As shown in fig. 5, the central control system sets the condition that each display triggers sleep. Then, the sending card monitors the data of the video played by the display screen. The trigger condition may be whether the black image time exceeds a threshold. If yes, the sending card issues a sleep instruction. The display screen enters a black picture according to the sleep instruction, and signals of the driving module and the row tube (the metal semiconductor field effect transistor in the embodiment) are turned off, and then, the output of the switching power chip is turned off. The display screen judges whether the display screen enters dormancy or not through whether the driving chip can read back the register or not. The sleep screen is a black screen in this embodiment, and in some embodiments, the sleep screen may be a predetermined cyclic play of one image or a plurality of images, or directly extinguish the screen.

Specifically, in the embodiment of the present application, the transmitting card may determine whether the control condition data is satisfied according to the state of the display screen. Specifically, the sending card judges the state of the display screen by the time when the display screen displays the black image, whether the display screen has a signal source, the chromaticity of the display screen and the refresh rate of the display screen. If the duration of displaying the black image by the display screen exceeds the duration threshold, the display screen does not have a video signal source, the chromaticity value is lower than the chromaticity threshold or the refresh rate is lower than the refresh rate threshold, the display screen shows that the current display screen does not display effective content, and therefore the video playing data are judged to meet the control condition data. It will be appreciated that in this embodiment, the control condition data is a sleep condition of the display screen.

In this embodiment, the display screen further includes an ac relay. The display screen can thoroughly close the current of the display box body when in dormancy, thereby realizing lower dormancy power consumption. Referring to fig. 6, fig. 6 is another schematic structural diagram of a display screen according to an embodiment of the present application. An ac relay is added to each display case as shown in fig. 6. After the display screen turns off the output of the switch power chip, the alternating current relay is further informed to turn off the power module, so that the display module, the control card and the power module stop working, and the display module, the control card and the power module enter a dormant state. Specifically, referring to fig. 7, fig. 7 is another schematic flow chart of a sleep entering process in an embodiment of the present application. As shown in fig. 7, after the sending card reads back the register through the driving chip, the power module is turned off through the ac relay, so that the display module, the control card and the power module stop working.

Specifically, the display screen may enter the awake state by controlling the power up of the display module of the display screen. Specifically, referring to fig. 8, fig. 8 is a schematic flow chart of entering a wake-up process in an embodiment of the present application. The central control system can set the condition that each display screen triggers awakening. Then, the sending card monitors the data of the video played by the display screen. The trigger condition may be whether the white image time exceeds a threshold. If yes, the sending card issues a wake-up instruction. The display screen starts the switch power chip to output direct-current voltage according to the wake-up instruction, and sends a drive channel closing instruction. Then, the display screen judges whether the driving chip can read back the register. If yes, the display screen sends a driving chip channel opening instruction, an image picture is output, and the display screen is completed to enter an awake state.

The display screen detects the voltage of the control card;

Specifically, in the wake-up process, the transmitting card turns on the power module through the ac relay. Specifically, referring to fig. 9, fig. 9 is a schematic flow chart of entering a wake-up process in an embodiment of the present application. After the display screen issues a wake-up instruction through the sending card, the alternating current relay is informed to start the ADC power supply. The display screen then checks whether the control card voltage is normal. If the control card is normal, the control card is started normally, and the control card and the switch power chip of the display screen are started to output direct-current voltage.

Acquiring video information to be played of a plurality of display screens;

And sending corresponding control condition data to each display screen.

The video information to be played is a play content designated for a display screen, which generally includes a plurality of video segments. The to-be-played video information comprises a time period for which the video needs to be played and a time period for which the video does not need to be played, and the central control module determines control condition data corresponding to the display screen according to which time in the to-be-played video information the video needs to be played, which time the video does not need to be played and the specific content of the video needing to be played.

The broadcast control module is typically between the central control module and the transmitting card. The playing control module processes the source video signal and the playing configuration issued by the central control module, programs the content to be played for the display screen, sends the video content to the sending card according to the arranging sequence, and the sending card forwards the received content to the display screen. Specifically, the central control system sends source data to the broadcast control module. The broadcast control module sends the source data to the sending card, and the sending card converts the source data into data which can be identified by the display screen and provides the data for the display screen.

The implementation details of the technical scheme of the embodiment of the application are described in detail below: referring to fig. 10, fig. 10 is a flowchart illustrating a display control method according to an embodiment of the present application, which may be specifically performed by a display control system, for example, a terminal or a server where the display control system is located. Referring to fig. 1, the display control includes at least steps S1010 to S1030, and is described in detail as follows:

Step S1010, determining control condition data corresponding to the display screen according to the video information to be played corresponding to the display screen.

The video information to be played is the play content specified by the control system of the display screen for the display screen, and typically includes a plurality of video segments. The to-be-played video information comprises a time period for which the video needs to be played and a time period for which the video does not need to be played, and the control system determines control condition data corresponding to the display screen according to which time for which the video needs to be played and which time for which the video does not need to be played and the specific content of the video which needs to be played in the to-be-played video information. The control condition data is used to define conditions that trigger a state switch of the display screen. It will be appreciated that the display may be switched between a plurality of states and the control system may set corresponding switching conditions for each state, for example, the states of the display may include a sleep state, an awake state, a high performance state, an emergency state, and the like. The control condition data may include trigger conditions or end conditions or both of one or more states. For example, a condition for triggering sleep and a condition for ending sleep may be included for the sleep state, a condition for triggering wake may be included for the wake state, and the like.

Step S1020, monitoring video playing data of the display screen.

The control system monitors the video play data of the display screen. Video play data of a display screen refers to data related to a video currently being played by the display screen. Such as the content of the video being played, the picture, the audio, the duration, the brightness, the refresh rate, etc. It can be understood that the video played by the display screen may be provided to the display screen by the control system, so that the video playing data of the display screen may be monitored by analyzing the video data to be sent to obtain the video playing data before transcoding the video data to be sent to the display screen, or collecting the content played by the display screen and analyzing the content to obtain the video playing data in the playing process of the display screen.

Step S1030, if the video playing data meets the control condition data, controlling the display screen to switch to the specified state according to the control instruction corresponding to the control condition data.

If the video playing data meets the control condition data, the display screen is required to be converted to a specified state currently, and therefore the control system controls the display screen to be converted to the specified state according to a control instruction corresponding to the control condition data. It is understood that there is a correspondence between the control condition data and the specified state, that is, the control condition data is used to determine whether to switch to the specified state. The control condition data, the control instruction and the appointed state have a corresponding relation, the control condition data is used for detecting whether to switch to the appointed state, the control instruction is used for enabling the display screen to switch to the appointed state, and the appointed state can be one of running states of the display screen, including a dormant state, a wake-up state and the like.

In some embodiments of the present application, based on the above technical solution, the control condition data includes a duration threshold, a chrominance threshold, and a refresh rate threshold; after monitoring the video playing data of the display screen, the scheme of the application further comprises the following steps:

Specifically, in an embodiment of the present application, the control system may determine whether the control condition data is satisfied according to the state of the display screen. Specifically, the control system judges the state of the display screen through the duration of displaying the black image on the display screen, whether the display screen has a signal source, the chromaticity of the display screen and the refresh rate of the display screen. If the duration of displaying the black image by the display screen exceeds the duration threshold, the display screen does not have a video signal source, the chromaticity value is lower than the chromaticity threshold or the refresh rate is lower than the refresh rate threshold, the display screen shows that the current display screen does not display effective content, and therefore the video playing data are judged to meet the control condition data. It will be appreciated that in this embodiment, the control condition data is a sleep condition of the display screen.

In some embodiments of the present application, based on the above technical solution, the step of controlling the display screen to switch to the specified state according to the control instruction corresponding to the control condition data specifically includes the following steps:

Specifically, the control system may enter a sleep state by controlling the display screen to display a sleep screen and powering down the display-related module. Specifically, the control system sets the condition that each display screen triggers dormancy. The display screen is then monitored for data of the video. The trigger condition may be whether the black image time exceeds a threshold. If so, issuing a sleep instruction. The display screen enters a black picture according to the sleep instruction, and turns off signals of the driving module and the row transistor chip (the metal semiconductor field effect transistor in this embodiment), and then turns off the output of the switching power chip. The control system judges whether the display screen enters dormancy or not through whether the driving chip can read back the register or not. The sleep screen is a black screen in this embodiment, and in some embodiments, the sleep screen may be a predetermined cyclic play of one image or a plurality of images, or directly extinguish the screen.

In some embodiments of the present application, based on the above technical solutions, the solution of the present application further includes the following steps:

In this embodiment, the display screen further includes an ac relay. The display screen can thoroughly close the current of the display box body when in dormancy, thereby realizing lower dormancy power consumption. An alternating current relay is added in each display box body. After the display screen turns off the output of the switch power chip, the power control module is further informed to turn off the power module, so that the display module, the control card and the power module stop working, and the display module, the control card and the power module enter a dormant state. Specifically, after the control system can read back the register through the driving chip, the power supply module is turned off through the power supply control module, so that the display module, the control card and the power supply module stop working. Then, in the corresponding wake-up process, the control system turns on the power module through the ac relay. Specifically, after the wake-up instruction is issued by the sending card, the control system notifies the alternating current relay to start the ADC power supply. And then checks whether the control card voltage is normal. If the power chip is normal, the control card is started normally, and finally the switch power chip is started through the control card to output direct-current voltage.

In some embodiments of the present application, based on the above technical solutions, after monitoring the video playing data of the display screen, the method further includes the following steps:

In this embodiment, the control condition data is a wake-up condition of the display screen. Specifically, the wake-up condition specifically includes display data containing a non-black image in the video playing data or the video playing data indicates that a video signal source exists on the display screen. In some embodiments, the length of time that a white image is displayed may be used as a criterion for determining a wake-up condition. Similar to the sleep flow, the wake-up conditions may also include conditions such as luminance values, chrominance values, and refresh rates.

Specifically, the control system may enter the wake-up state by controlling the display module of the display screen to power up. Specifically, the control system sets the conditions for each display to trigger wakeup. The display screen is then monitored for data of the video. The trigger condition may be whether the white image time exceeds a threshold. If yes, a wake-up instruction is issued. The display screen starts the switch power chip to output direct-current voltage according to the wake-up instruction, and sends a drive channel closing instruction. Then, it is determined whether the driver chip can read back the register. If yes, a driving chip channel opening instruction is sent, an image picture is output, and the display screen is completed to enter an awake state.

In some embodiments of the present application, based on the above technical solutions, the steps described above determine control condition data corresponding to a display screen according to video information to be played corresponding to the display screen, and specifically include the following steps:

Acquiring video information to be played of a plurality of display screens;

And sending corresponding control condition data to each display screen.

In this embodiment, the control system may acquire video information to be played on a plurality of display screens. Video information to be played typically one or more videos that each display screen needs to play over a period of time. The video information to be played may be different for different display screens. And the control system generates dormancy condition data and wake-up condition data corresponding to each display screen according to the video information to be played of each display screen, and obtains control condition data of each display screen. And finally, the control system sends corresponding control condition data to each display screen, so that the dormancy and awakening conditions of each display screen are configured.
